Hereinafter, embodiments of the present invention will be described.

The functional material construction structure 1 in the present embodiment includes a functional material 20, a decorative material 10 facing the functional material 20, and a plurality of fasteners 80. The fastener 80 is arranged between the functional material 20 and the decorative material 10 so as to overlap the functional material 20 and holds the decorative material 10.

As shown in FIGS. 1 and 2, the functional material 20 is composed of a plurality of sheet members 27, and the functional material 20 is a thick portion 21 formed by stacking two or more sheet members 27. Has. Each of the plurality of fasteners 80 is arranged so that the arrangement height in the direction in which the functional material 20 and the decorative material 10 face each other (front-rear direction) is within 2 mm from the reference plane. Alternatively, each of the plurality of fasteners 80 is arranged so as not to overlap the thick portion 21.

The reference plane is a virtual plane including a region on the plane on which the fastener 80 is installed that does not overlap with the thick portion 21. For example, when the fastener 80 is directly installed on the functional material 20, the surface of the functional material 20 facing the decorative material 10 is the surface on which the fastener 80 is installed, and the surface of the functional material 20. The reference plane is a virtual plane including a region without the thick portion 21. Further, when the moisture permeable waterproof sheets 65 and 271 are interposed between the functional material 20 and the fastener 80 as described later, the surface of the moisture permeable waterproof sheets 65 and 271 facing the decorative material 10 is the fastener. The surface on which 80 is installed, and the virtual plane including the region of the surfaces of the moisture permeable waterproof sheets 65 and 271 that does not overlap with the thick portion 21, is the reference surface. The same applies when an appropriate member other than the moisture permeable waterproof sheets 65 and 271 is interposed between the functional material 20 and the fastener 80. It can be said that the arrangement height is the distance between the reference surface and the fastener 80 in the front-rear direction.

Note that FIGS. 1 and 2 show the positional relationship between the support member 50 (detailed later), the seat member 27, and the fastener 80, and other elements are not shown.

According to this embodiment, the functional material 20 can improve the functions such as the fire resistance of the functional material construction structure 1. Further, the position of each fastener 80 in the front-rear direction is less likely to be excessively lifted forward by the thick portion 21. Therefore, the displacement in the front-rear direction between the plurality of fasteners is less likely to occur. Further, the position shift in the front-rear direction due to the thick portion 21 is unlikely to occur between the fasteners 80, so that the fastener 80 is likely to hold the decorative material 10 and the decorative material 10 is also unlikely to be displaced. .. Therefore, the workability of the functional material construction structure 1 is good, and the finish of the decorative material 10 is not impaired.

The thick portion 21 includes, for example, a portion formed by overlapping two sheet members 27 (two overlapping portion 212) and a portion formed by overlapping three sheet members 27 (three overlapping portion 213). , At least one of a portion (four-sheet stacking portion 214) formed by overlapping the four sheet members 27 may be provided. The double-layered portion 212 is a portion formed by overlapping the edge edges of the two sheet members 27, as shown in FIGS. 1 and 2, for example. As shown in FIG. 1, for example, the four-layered portion 214 is a portion formed by overlapping the corners of the four sheet members 27. As shown in FIG. 2, for example, the three-sheet stacking portion 213 is a portion formed by overlapping the edge of one sheet member 27 and each corner of the two sheet members 27.

The thickness of one sheet member 27 is, for example, 0.1 mm or more and 5 mm or less, more preferably 0.3 mm or more and 3 mm or less, and further preferably 0.4 mm or more and 1 mm or less.

It is preferable that none of the plurality of fasteners 80 overlaps the thick portion 21.

When the fastener 80 overlaps the thick portion 21, it is preferable that the arrangement height of the fastener 80 is within 2 mm as described above. For that purpose, it is preferable that the fastener 80 overlaps only the arrangement portion in the thick portion 21. The arrangement portion is a portion where the difference in thickness from one sheet member 27 is within 2 mm. In this case, it is easy to realize that the arrangement height is within 2 mm. For example, if the thickness of one sheet member 27 is larger than 2/3 mm and 1 mm or less, it is possible to use the two-sheet stacking portion 212 and the three-sheet stacking portion 213 as placement sites, and the thickness of one sheet member 27 is 1 mm. If it is larger and 2 mm or less, it is possible to use the double-layered portion 212 as the arrangement portion. The difference between the thickness of the arrangement portion and the thickness of one sheet member 27 is preferably 2 mm or less, more preferably 1.8 mm or less, and even more preferably 1 mm or less.

In constructing the sheet member 27, it is preferable that a long portion of the thick portion 21 along the longitudinal direction of the support member 50 (particularly, the fastener support member 501 described later) does not overlap with the support member 50. This portion is formed by overlapping the edge edges (for example, the side edges) of the seat member 27 along the support member 50. Further, it is preferable that the portion of the thick portion 21 that is long in the direction intersecting the longitudinal direction of the support member 50 does not overlap with the position of the fastener 80. This portion is formed by overlapping the edge edges (for example, the upper end and the lower end) of the seat member 27 along the direction intersecting the longitudinal direction of the support member 50. In this case, the fastener 80 supported by the fastener support member 501 is likely to be arranged so as not to overlap the thick portion 21.

A more specific example of the functional material construction structure of the present embodiment is shown.

(Embodiment 1)
(1) Schematic FIGS. 3, 4 and 5 show an outer wall structure 2 as a functional material construction structure 1 of the present embodiment. The outer wall structure 2 includes a decorative material 10, a functional material 20, a base material 30, a heat insulating material 40, and a support material 50. The decorative material 10, the functional material 20, the base material 30, the heat insulating material 40, and the supporting material 50 are arranged in this order in the front-rear direction. That is, the base material 30 is arranged in front of the heat insulating material 40 and the support material 50. Further, the functional material 20 is arranged in front of the base material 30. Further, the decorative material 10 is arranged in front of the functional material 20. In the present specification, the front-rear direction is the direction in which the functional material 20 and the decorative material 10 face each other, and is the thickness direction of the outer wall structure 2, which is the same as the indoor / outdoor direction. The front side is the side from the functional material 20 to the decorative material 10 in the front-rear direction, and the rear side is the opposite side of the front side. The left-right direction and the up-down direction are defined with reference to the front-back direction.

(2) Cosmetic material 10
The decorative material 10 is an exterior material of the functional material construction structure 1, and the functional material construction structure 1 is decorated with the decorative material 10. In the case of the outer wall structure 2, the decorative material 10 is an outer wall material, for example, a ceramic siding. Ceramic siding is a cured product of a hydraulic material containing cement. Although the decorative material 10 is formed in a substantially flat plate shape, it is preferable that the decorative material 10 has an uneven pattern or a coating film on the surface thereof and has a design property. The thickness of the decorative material 10 is formed to be, for example, 10 mm or more and 50 mm or less, but is not limited thereto. The shape of the decorative material 10 is also arbitrary, but for example, it is formed in the shape of a rectangular plate when viewed from the front (when viewed from the rear). The decorative material 10 has fruits. An actual recess 101 is provided at the upper end of the decorative material 10. A real convex portion 102 is provided at the lower end portion of the decorative material 10. The decorative material 10 to be installed adjacent to the top and bottom is connected by fitting the actual concave portion 101 and the actual convex portion 102. The decorative material 10 may be a metal-based siding material obtained by molding a metal plate.

(3) Functional material 20
The functional material 20 improves the function of the functional material construction structure 1. The functional material 20 is, for example, a sound insulating material, a waterproof material, or a refractory material, but is not limited thereto. When the functional material 20 is a refractory material, the functional material 20 improves the fire resistance of the functional material construction structure 1. Therefore, for example, the functional material 20 foams due to the heat of the fire to increase the volume from the initial state before the fire. Here, fire resistance means suppressing heat transfer.

The functional material 20 can be formed of a plurality of sheet members 27. When the functional material 20 is a refractory material, the sheet member 27 can be formed of, for example, a rectangular effervescent refractory sheet in front view, in which case a synthetic resin, a polyhydric alcohol, and a flame-retardant foam. Those containing an agent or the like are preferable.

Examples of the synthetic resin include melamine resin, acrylic resin, alkyd resin, vinyl chloride resin, vinyl acetate resin, urethane resin, epoxy resin, silicone resin, polyester resin, polyolefin / vinyl acetate resin, and vinyl acetate / vinyl acetate resin. Examples thereof include a polymer resin, a vinyl acetate / polyolefin resin, a vinyl acetate / versatic acid / acrylic resin, a vinyl acetate / acrylic copolymer resin, an acrylic / styrene copolymer resin, and a polybutadiene resin. Examples of the polyolefin include polyethylene and the like.

Examples of the polyhydric alcohol include pentaerythritol, dipentaerythritol, tripentaerythritol, polypentaerythritol and the like.

As the flame-retardant effervescent agent, phosphates such as ammonium phosphate, ammonium polyphosphate, melamine phosphate, melamine polyphosphate, aluminum polyphosphate, magnesium polyphosphate and the like are preferably used, but sulfamate (sulfamic acid) (Sulfamine ammonium, etc.), borate (ammonium borate, etc.), expansive graphite, etc. can be exemplified.

The content ratio of the synthetic resin, polyhydric alcohol, and flame-retardant foaming agent in the functional material 20 is as follows: polyhydric alcohol is 10 parts by mass or more and 50 parts by mass or less, and the flame-retardant foaming agent is 100 parts by mass. It is preferably 50 parts by mass or more and 200 parts by mass or less.
The thickness of the sheet member 27 is preferably 0.1 mm or more and 5 mm or less, more preferably 0.3 mm or more and 3 mm or less, and further preferably 0.4 mm or more and 1 mm or less.

In order to enhance the heat-shielding property of the functional material 20 after foaming, it is preferable that the volume ratio after foaming (foaming ratio) of the functional material 20 is 10 to 30 times as compared with the volume before foaming. For example, by using a sheet-like functional material 20 having a thickness of 0.6 mm for a 15 mm ventilation layer formed between the decorative material 10 and the base material 30, the foaming ratio becomes 25 times, and fire resistance is relatively inexpensive. You can improve your sex. Further, for the portion where the fire resistance is enhanced, for example, when a 1.2 mm sheet-shaped functional material 20 is used and the foaming ratio is 12.5 times, the fire resistance is further enhanced.

(4) Base material 30
The functional material construction structure 1 preferably includes a base material 30. The base material 30 is nonflammable, has a flat plate shape, and is formed harder than the functional material 20. The base material 30 is formed of a plurality of base members 35. As the base member 35, for example, a gypsum board, a calcium silicate board, or the like, which is rectangular in front view, is used. The thickness of the base member 35 can be, for example, 5 mm or more and 30 mm or less, preferably 9 mm or more and 21 mm or less, but is not limited thereto. The base member 35 conforms to the provisions of Article 68-26, Paragraph 1 of the Building Standards Act, Article 2-9 of the same Act, and Article 108-2 (non-combustible material) of the Enforcement Ordinance of the same Act. It is preferable that the product is certified by the Minister of Land, Infrastructure, Transport and Tourism.

(5) Insulation material 40
The functional material construction structure 1 preferably includes a heat insulating material 40. The heat insulating material 40 improves the heat insulating property of the functional material construction structure 1. That is. This is for reducing the amount of heat passing through the functional material construction structure 1 in the front-rear direction. Here, the heat insulating property means the performance of reducing the inflow and outflow of heat.

The heat insulating material 40 is preferably made of a material having high fire resistance and nonflammability. For example, the heat insulating material 40 is formed by using a fiber-based heat insulating material such as an artificial mineral fiber-based heat insulating material (for example, rock wool or glass wool) as a material. The form of the heat insulating material 40 is, but is not limited to, board or cotton. The density of the heat insulating material 40 is 10 kg / m ³ or more and 32 kg / m ³ or less, preferably 15 kg / m ³ or more and 25 kg / m ³ or less, and the thickness is 50 mm or more and 150 mm or less, preferably 80 mm or more and 120 mm or less. When the density and thickness of the heat insulating material 40 are within the above-mentioned predetermined ranges, the heat insulating performance is not easily impaired, and heat retention can be reduced.

(6) Support material 50
The functional material construction structure 1 preferably includes a plurality of support materials 50. As shown in FIG. 4, the support material 50 is attached with the decorative material 10 and the base material 30 to support them. The support member 50 is a member long in the vertical direction, and is formed as, for example, a furring strip. The support member 50 is made of metal and is made of, for example, C-shaped steel (grooved steel with a lip). In addition to this, the support member 50 is made of shaped steel having various cross-sectional shapes, and is made of, for example, a square steel pipe, a channel steel, or the like.

The support member 50 has a mounting portion 51. The mounting portion 51 is formed in a flat plate shape that is long in the vertical direction. The base material 30 is attached to the attachment portion 51. The support member 50 has an opposing portion 52. The facing portion 52 is formed on a flat plate that is long in the vertical direction. The facing portion 52 is located behind the mounting portion 51 and faces the mounting portion 51. The support member 50 has a joint portion 53. The connecting portion 53 is formed on a flat plate that is long in the vertical direction. One end of the connecting portion 53 in the short side (width) direction is connected to one end of the mounting portion 51 in the short side (width) direction over the entire length. The other end of the connecting portion 53 in the short side (width) direction is connected to one end of the facing portion 52 in the short side (width) direction over the entire length. Reinforcing portions 55 are provided over the entire length of the support member 50 in the vertical direction at the end portion of the mounting portion 51 opposite to the joint portion 53 side and the end portion of the facing portion 52 opposite to the joint portion 53 side. ing.

(7) Overall Structure The outer wall structure 2 formed as the functional material construction structure 1 is configured as follows.

As shown in FIG. 6, a plurality of support members 50 are provided on the upper side of the foundation 63 via the base 64. The plurality of support members 50 are arranged one by one in the left-right direction with a predetermined interval. Further, two or more support members 50 may be arranged in combination. When two support members 50 are combined, the outer surfaces of the joint portions 53 can be joined to each other.

A plurality of base members 35 are attached to the front of the plurality of support members 50. The plurality of base members 35 are arranged side by side in the vertical direction and the horizontal direction. The base member 35 adjacent in the vertical direction is attached so that the lower end of the upper base member 35 and the upper end of the lower base member 35 abut against each other. Further, the base member 35 adjacent in the left-right direction is attached so that the left end of the base member 35 on the right side and the right end of the base member 35 on the left side abut against each other. That is, the base members 35 arranged vertically are adjacent to each other via the adjacent portion 31, and the base members 35 arranged in the left-right direction are adjacent to each other via the adjacent portion 32. Each base member 35 is attached and fixed to the attachment portion 51 of the support member 50 with a fixture 33 such as a screw or a nail.

It is desirable that the adjacent portion 32 of the base member 35 arranged in the left-right direction is positioned in front of the mounting portion 51 of the support member 50. As a result, even if the base member 35 is deformed in the event of a fire and a gap is formed in the adjacent portion 32, the fire resistance performance is not easily impaired because the mounting portion 51 closes the base member 35. Further, in the present embodiment, the rectangular base member 35 is constructed in a horizontally long shape, but it may be constructed in a vertically long shape.

The heat insulating material 40 is arranged on a surface (rear surface) facing the rear of the base material 30. The plurality of heat insulating materials 40 are arranged between adjacent support members 50. The heat insulating material 40 may be fixed to the rear surface of the base material 30 with an adhesive or the like. In addition to bonding, the heat insulating material 40 can also be fixed to the base material 30 with an adhesive tape. The heat insulating material 40 is preferably in close contact with the rear surface of the base material 30. As a result, a space that communicates vertically is not formed between the base material 30 and the heat insulating material 40, and the heat transferred from the base material 30 is suppressed from moving in the vertical direction between the base material 30 and the heat insulating material 40. can do. When the support material 50 is made of wood, it may be fixed to the support material 50 with a tacker stopper or the like. Further, the heat insulating material 40 can be fixed to the support material 50 with an adhesive tape.

As shown in FIGS. 7, 8A and 8B, the functional material 20 is arranged on the front side of the base material 30. Since the functional material 20 is formed of a plurality of sheet members 27, the plurality of sheet members 27 are arranged side by side in the vertical and horizontal directions. The sheet member 27 is fixed to the base material 30 by a fixture 23 such as a tacker.

The seat member 27 is constructed so that the ends 26 of the adjacent seat members 27 in the functional material 20 overlap each other. Therefore, the functional material 20 has a thick portion 21 formed by overlapping the end portions 26 of the sheet member 27 with each other. In the present embodiment, the thick portion 21 has a double-layered portion 212 formed by overlapping the upper end portion 26a of the sheet members 27 that are vertically adjacent to each other and the lower end portion 26b of the seat member 27.

After the functional material 20 is installed, a plurality of fasteners 80 are arranged so as to overlap the front surface of the functional material 20 as described later. At this time, in the present embodiment, as described above, each of the plurality of fasteners 80 is arranged so that the arrangement height is within 2 mm, or is arranged so as not to overlap the thick portion 21.

Here, as shown in FIGS. 8A and 8B, a mark portion 22 is provided on the surface of the sheet member 27. The mark portion 22 serves as a guide when attaching the sheet member 27 to the base material 30. For example, the mark portion 22 is formed in a long linear shape in the left-right direction, and the operator fixes the seat member 27 with the fixture 23 while aligning the mark portion 22 and the adjacent portion 31. It is also possible to adjust the overlapping dimension of the adjacent sheet members 27 with the mark portion 22 as a guide. Further, the mark portions 22 can be formed by broken lines, and the intervals between the broken lines can be made equal, for example, at a pitch of 100 mm. In this case, the sheet member 27 can be constructed with the interval of the broken lines as a guide. Further, a broken line of the mark portion 22 is formed at a position that is line-symmetrical about the center of the sheet member 27 in the width direction so as to coincide with the broken line of the other mark portion 22 in the width direction, and the mark portion 22 is line-symmetrical. It is also possible to match the broken lines with each other and use it as a guide when cutting the sheet member 27 at a right angle.

For example, as shown in FIG. 11A, the thick portion 21 is formed at a position corresponding to the adjacent portion 31 of the vertically adjacent base member 35. The thick portion 21 is formed by overlapping the end portions 26 of the sheet member 27 with each other. Further, the present invention is not limited to this, and for example, as shown in FIG. 11B, by folding back the end portion 26 of the seat member 27, a portion where the seat member 27 is doubly overlapped can be formed as a thick portion 21. The doubly overlapped portion in FIG. 11B constitutes the double-layered portion 212. That is, a portion where the sheet members 27 are doubly overlapped by folding back one sheet member 27 is regarded as a portion where the two sheet members 27 are overlapped. Further, as shown in FIG. 11C, another short piece-shaped functional material (fireproof sheet member) 25 is superposed on the surface of the functional material 20, and the portion where the two sheet-shaped functional materials 20 overlap is a thick portion. It can be formed as 21. The portion where the two sheet-shaped functional materials 20 overlap in FIG. 11C also constitutes the double-layered portion 212. The thick portion 21 is preferably formed in a portion of the functional material 20 corresponding to the boundary between adjacent base members 35, and is provided at least in a portion not facing the support member 50.

The roll-shaped long sheet has been described as an example of the functional material 20 (seat member 27), but the present invention is not limited to this, and the functional material 20 (seat member 27) having a size slightly larger than that of the base member 35 is used. There may be. For example, as shown in FIG. 8B, a case will be described in which the base member 35 is composed of a rectangular base member 35 and a rectangular sheet member 27, and the base member 35 is installed in a horizontally long shape. The rectangular base member 35 and the rectangular sheet member 27 have substantially the same dimensions on the long side, and the rectangular seat member 27 is longer than the base member 35 having a rectangular short side. As an example, the rectangular base member 35 is 1820 mm (long side) × 606 mm (short side), and the rectangular sheet member 27 is 1820 mm (long side) × 700 mm (short side). The construction using the rectangular base member 35 and the rectangular sheet member 27 will be described. The construction of the rectangular base member 35 and the moisture-permeable waterproof sheet 65 described below will be omitted because they are the same.

A plurality of rectangular base members 35 are vertically and horizontally abutted and attached to the front of the support member 50, and the adjacent portions 32 of the base members 35 arranged in the left-right direction may be positioned in front of the attachment portion 51 of the support member 50. desirable. Then, the rectangular sheet member 27 is fixed in front of the rectangular base member 35 with a tacker. At that time, the short side of the rectangular base member 35 and the short side of the rectangular sheet member 27 are substantially matched. On the other hand, the long side of the rectangular base member 35 and the long side of the rectangular sheet member 27 do not match, and the upper and lower long sides of the rectangular sheet member 27 are each of the rectangular base member 35. Approximately the same dimensions protrude from the top and bottom long sides to the top and bottom. That is, the upper end portion 26a of the rectangular sheet member 27 is located above the upper long side of the rectangular base member 35, and the lower end portion 26b of the rectangular sheet member 27 is below the rectangular base member 35. It is located below the long side of the side. When constructing the lowermost rectangular sheet member 27, the lower long side of the rectangular base member 35 is matched with the lower long side of the rectangular sheet member 27 to form a rectangular shape. The sheet member 27 may protrude only above the long side on the upper side of the rectangular base member 35. When constructing the rectangular sheet member 27 on the surface of the rectangular base member 35 in this way, a guideline for attaching the mark portion 22 provided on the rectangular sheet member 27 to the base material 30 in the same manner as described above. Can be. As shown in FIG. 9, the adjacent position (boundary) 29 of the sheet members 27 arranged in the left-right direction may be laterally displaced from the adjacent portion 32 of the support member 50 and the base member 35 arranged in the left-right direction.

By constructing the rectangular sheet member 27 from the lower stage to the upper side, two protruding portions can be overlapped on the front side (front side). This overlapping portion is formed as a thick portion 21. When the thick portion 21 is located in front of the adjacent portion 31 of the rectangular base member 35, the fire resistance can be improved. Further, in the present embodiment, the abutting portion of the short side of the rectangular base member 35 and the abutting portion of the short side of the rectangular sheet member 27 are substantially matched in the front-rear direction, but the present invention is not limited to this. The abutting portion may be displaced in the left-right direction.

By making the sizes of the base member 35 and the sheet member 27 close to each other in this way, construction, packaging, transportation, and the like can be improved. In the present embodiment, the case where the rectangular base member 35 is installed horizontally has been described, but the rectangular base member 35 may be installed vertically. In this case, the rectangular sheet member 27 has a short side having substantially the same dimensions as the short side of the rectangular base member 35, and the long side is longer than the long side of the rectangular base member 35.

In the present embodiment, after the functional material 20 is attached to the base material 30 over the entire surface, the moisture permeable waterproof sheet 65 is attached to the front surface of the functional material 20 before the fastener 80 is installed. The moisture permeable waterproof sheet 65 is a sheet that allows moisture to pass through and does not allow water droplets to pass through. The moisture permeable waterproof sheet 65 is also attached with a fixture such as a tacker. The moisture permeable waterproof sheet 65 is attached over the entire surface of the functional material 20. A waterproof sheet that does not allow moisture to pass through may be provided instead of the moisture permeable waterproof sheet 65.

Next, the plurality of fasteners 80 are arranged so as to overlap the functional material 20. In the present embodiment, a plurality of fasteners 80 are arranged in front of the moisture permeable waterproof sheet 65. The fastener 80 is arranged in front of the breathable waterproof sheet 65. In the present embodiment, the support member 50 includes the fastener support member 501, and the fastener 80 is fixed to the fastener support member 501 by a fixture 86 such as a screw. As a result, the plurality of fasteners 80 are superposed on the functional material 20 via the moisture permeable waterproof sheet 65.

In constructing the fastener 80, as described above in the present embodiment, each of the plurality of fasteners 80 is arranged so that the arrangement height is within 2 mm, or is arranged so as not to overlap the thick portion 21. Will be done. Therefore, it is unlikely that the position of each fastener 80 in the front-rear direction is excessively lifted forward by the thick portion 21, and therefore, the position shift in the front-rear direction between the plurality of fasteners 80 is less likely to occur. ..

As shown in FIG. 10, the decorative material 10 is held in front of the moisture permeable waterproof sheet 65 by being held by the fastener 80. A plurality of decorative materials 10 are arranged, and each decorative material 10 is held by a plurality of fasteners 80. That is, the upper end of the decorative material 10 is hooked and held by the fastener 80 arranged on the upper side of the decorative material 10, and the lower end of the decorative material 10 is hooked on the fastener 80 arranged on the lower side of the decorative material 10. Be held. Further, the decorative materials 10 adjacent to the top and bottom are connected by the actual joining of the actual convex portion 102 and the actual concave portion 101. Further, as shown in FIGS. 4 and 10, a joint material 81 is arranged between the decorative materials 10 adjacent to each other in the left-right direction. A sealing material 83 is provided on the front side of the joint material 81. A drainer 84 is provided below the lowermost decorative material 10. A ventilation layer 85 is formed behind the decorative material 10. That is, the ventilation layer 85 is formed between the rear surface of the decorative material 10 and the front surface of the moisture permeable waterproof sheet 65.

In the present embodiment, as described above, the plurality of fasteners 80 are unlikely to be displaced from each other in the front-rear direction. Therefore, since the decorative material 10 is less likely to be displaced in the front-rear direction, the appearance is less likely to be deteriorated due to the displacement and the waterproof property between the adjacent decorative materials 10 is less likely to be deteriorated. Further, the workability is good when the decorative material 10 is held by the fastener 80 for construction.

The thick portion 21 is also provided as a high fireproof portion 24. The high fireproof portion 24 is a portion of the heat foamable sheet 240 that has higher fire resistance than other portions, which is arranged at a portion corresponding to an adjacent portion of the outer fireproof board 230. That is, the thick portion 21 may be arranged at a position corresponding to the adjacent portion of the outer fireproof board 230 in the heat-foamable sheet 240.

It is preferable that the joints of the adjacent decorative material 10 and the joints of the adjacent base member 35 are shifted so as not to overlap each other in the front view. That is, it is preferable that the position of the sealing material 83 between the decorative materials 10 adjacent in the left-right direction and the position of the adjacent portion 32 of the base member 35 adjacent in the left-right direction are shifted so as not to overlap each other in the front view. Further, it is preferable that the position of the adjacent portion 11 of the decorative material 10 adjacent in the vertical direction and the position of the adjacent portion 31 of the base member 35 adjacent in the vertical direction are shifted so as not to overlap in the front view. In this case, even if a flame invades the joint and the adjacent portion 11 of the adjacent decorative material 10 from the front, it becomes difficult for the flame to directly invade the joint and the adjacent portion 31 of the adjacent base member 35, and the fire resistance is improved. Can be made to. However, if the joints of the decorative material 10 adjacent to each other in the left-right direction and the joints of the base member 35 adjacent to each other in the left-right direction coincide with the support material 50 in the front view, it is not necessary to shift both joints.

In the functional material construction structure 1 (outer wall structure 2) formed as described above, in particular, when the sheet member 27 is a heat-foamable sheet 240 and the functional material 20 has foamability, in the event of a fire, , The functional material 20 is heated from the outdoor side of the decorative material 10 and expands by foaming and expanding in the ventilation layer 85. That is, the ventilation layer 85 is formed as a foamed space 88 for the functional material 20 to foam and expand. As a result, the heat-shielding effect and the flame-shielding effect of the foamed and expanded functional material 20 can reduce the invasion of flames and heat from the outside to the inside, and therefore, the fire resistance can be improved. At the same time, the foamed and expanded functional material 20 does not form a space that communicates vertically between the decorative material 10 and the base material 30, and heat is transferred in the vertical direction between the decorative material 10 and the base material 30. Can be suppressed. Further, by providing the functional material 20 behind the decorative material 10, the functional material 20 is not required to have high weather resistance and water resistance, and the fire resistance can be improved. Further, since the functional material 20 is a thin material if there is no fire, it does not normally hinder the ventilation layer 85, and the dimensions of the functional material construction structure 1 in the front-rear direction (dimensions from the decorative material 10 to the base material 30). ) Is less likely to increase than the conventional one. Further, by providing the heat insulating material 40, heat is less likely to be transferred to the rear (indoor side) of the base material 30, which can further improve the fire resistance.

(Embodiment 2)
The functional material construction structure 1 of the present embodiment shown in FIG. 12 is a support material 50 provided with a filler 54. Hereinafter, the same configurations as those in the first embodiment will be designated by a common reference numeral and description thereof will be omitted as appropriate. The configuration described in the second embodiment can be applied in combination with the configuration described in the first embodiment as appropriate.

By filling the hollow portion 56, which is the space inside the support member 50, with the filler 54, the hollow portion 56 is closed with the filler 54. That is, the filling material 54 closes the vertical communication of the hollow portion 56, which is a space surrounded by the mounting portion 51 of the support member 50, the facing portion 52, the connecting portion 53, and the reinforcing portion 55. By filling the hollow portion 56 of the support member 50 with the filler 54 and closing the support member 50 in this way, heat is less likely to be transferred through the hollow portion 56, and fire resistance can be improved.

The filler 54 can be formed by extending the heat insulating material 40. That is, the filler 54 is formed of a fibrous heat insulating material such as rock wool or glass wool, which is the same material as the heat insulating material 40. In this case, the heat at the time of the fire is insulated by the filler 54 and is difficult to be transmitted, the heat transfer to the indoor side is reduced, and the fire resistance can be improved. Further, the filler 54 can also be installed by the work of attaching the heat insulating material 40 to the base material 30 and a series of operations, and the cost can be reduced by standardizing the members and simplifying the work.

(Embodiment 3)
The functional material construction structure 1 according to the present embodiment is different from the functional material construction structure 1 according to the first or second embodiment in the configuration on the indoor side (indoor side) of the base material 30. Hereinafter, the same configurations as those of the first and second embodiments will be designated by common reference numerals and description thereof will be omitted as appropriate. The configuration described in the third embodiment can be applied in appropriate combination with the configuration (including a modification) described in the first or second embodiment.

The material 20, the foam space 88, and the decorative material 260 are sequentially arranged.

In the present embodiment, the base material 30 is composed of the outer fireproof board 230. As the inner refractory board 210, the same one as the "base member 35" in the first and second embodiments can be used.

Here, the "indoor side" and the "outdoor side" in the present embodiment correspond to the "indoor side" and the "outdoor side" in the first and second embodiments, respectively.

The metal support member 50 includes a vertical support member 221, a runner 222, and an inner vertical support member (stud) 223. In FIG. 15, the support member 50 is U-shaped when viewed in the longitudinal direction thereof, but the support member 50 is not limited to this and may be square-shaped.

The runner 222 is located on the indoor side of the vertical support member 221. The runner 222 includes an upper runner (not shown) and a lower runner 225. The upper runner is placed on the ceiling surface. The lower runner 225 is arranged on the floor. The upper runner is formed of a channel material (rail material) having a substantially U-shaped cross section that opens downward. The lower runner 225 is formed of a channel material (rail material) having a substantially U-shaped cross section that opens upward. Each runner 222 is formed long in the left-right direction (substantially horizontal direction) when the indoor side surface or the outdoor side surface of the functional material construction structure 1 is viewed from the front. The upper runner may be fixed to the ceiling surface or may be fixed to the vertical support member 221. The lower runner may be fixed to the floor surface or may be fixed to the vertical support member 221.

There are a plurality of inner vertical support members 223, and each inner vertical support member 223 is formed of a channel material (rail material) having a substantially U-shaped cross section that opens laterally. Each inner vertical support member 223 is formed long in the vertical direction (substantially vertical direction). The ends of each inner vertical support member 223 are held by the runner 222. The upper end of each inner vertical support member 223 is inserted into and held by the upper runner. The lower end of each inner vertical support member 223 is inserted and held in the lower runner 225. The inner vertical support member 223 may have a substantially square cross section.

The outer refractory board 230 (base member 35) is preferably a gypsum board having a thickness of 15 mm or more.

Similar to the first and second embodiments, the functional material 20 is composed of a sheet member 27 and has a thick portion 21. The size of the sheet member 27 may be one size larger than the external dimensions of the outer fireproof board 230, and the vertical and horizontal sides may be superposed.

The functional material construction structure 1 of the present embodiment has a configuration in which the heat insulating material 40 located on the indoor side (indoor side) of the base material 30 is removed from the structures of the first and second embodiments, and has a runner 222 and an inner vertical length. It is a configuration in which a support material 223 is added. In other configurations, the functional material construction structure 1 of the present embodiment and the functional material construction structure 1 of the first and second embodiments are substantially the same.

In the functional material construction structure 1 of the present embodiment, a plurality of vertical support members 221 are provided on the upper side of the foundation 63 via a base 64. The plurality of vertical support members 221 are arranged one by one in the left-right direction with a predetermined interval. A plurality of outer refractory boards 230 are attached to the front (outdoor side) of the plurality of vertical support members 221. The plurality of outer fireproof boards 230 are arranged side by side in the vertical direction and the horizontal direction. The outer fireproof board 230 adjacent in the vertical direction is attached so that the lower end of the upper outer fireproof board 230 and the upper end of the lower outer fireproof board 230 abut against each other. Further, the outer fireproof boards 230 adjacent to each other in the left-right direction are attached so that the left end of the outer fireproof board 230 on the right side and the right end of the outer fireproof board 230 on the left side abut each other. Each outer refractory board 230 is attached and fixed to the attachment portion 51 of the vertical support member 221 with a fixture such as a screw or a nail. The plurality of outer refractory boards 230 form a base material 30 similar to the case shown in FIG.

The outer fireproof boards 230 arranged in the left-right direction abut the vertical sides 231 to each other to form the vertical side abutting portion 234. It is desirable that the vertical side abutting portion 234 is positioned in front of the mounting portion 51 of the vertical support member 221. As a result, even if the outer fireproof board 230 is deformed in the event of a fire and a gap is formed in the vertical side abutting portion 234, the fireproof performance is not impaired because the mounting portion 51 is closed. In the present embodiment, the rectangular outer fireproof board 230 is installed horizontally, but it may be installed vertically.

A sheet member 27 is arranged on the outdoor side of the outer refractory board 230 fixed to the vertical support member 221 in the same manner as in the case shown in FIG. The sheet member 27 is, for example, a heat-foamable sheet 240. The seat members 27 are arranged side by side in the vertical and horizontal directions. The seat member 27 is fixed to the outer refractory board 230 with a fixture such as a tacker. Here, it is preferable that the surface of the sheet member 27 is provided with a mark portion similar to the mark portion 22 shown in FIGS. 8 and 9. This serves as a guide when attaching the seat member 27 to the outer refractory board 230.

At a position corresponding to the side abutting portion 233 of the outer fireproof board 230 adjacent to the top and bottom, the side end portions 241 of the sheet members 27 located above and below are overlapped with each other. As a result, the thick portion 21 is formed. The vertical dimension of the thick portion 21 (the dimension in which the lateral side end portions 241 are overlapped with each other) L1 can be 50 mm or more. The thick portion 21 may be formed not only in a portion corresponding to an adjacent portion of the outer fireproof board 230 adjacent to the top and bottom, but also in a portion corresponding to an adjacent portion of the outer fireproof board 230 adjacent in the left-right direction. The thick portion 21 may be formed in a portion corresponding to a boundary (butting portion) between the outer fireproof boards 230 adjacent to each other in the left-right direction as well as in the vertical direction.

The long side of the rectangular outer fireproof board 230 and the long side of the rectangular sheet member 27 do not match, and the upper and lower long sides of the rectangular sheet member 27 are each of the rectangular outer fireproof board 230. Approximately the same dimensions can be projected from the upper and lower long sides to the upper and lower sides. In this case, the upper end of the rectangular sheet member 27 is located above the upper long side of the rectangular outer fireproof board 230, and the lower end of the rectangular sheet member 27 is the rectangular outer fireproof board 230. It is located below the lower long side.

When constructing the lowermost rectangular sheet member 27, the lower long side of the rectangular outer fireproof board 230 is made to match the lower long side of the rectangular sheet member 27, and is rectangular. The shaped sheet member 27 may protrude only above the long side on the upper side of the rectangular outer fireproof board 230. Further, a base drainer 84 is arranged on the outdoor side of the lowermost sheet member 27, and a lower end portion of the waterproof layer 270 is located on the outdoor side of the upper part of the base drainer 84. The waterproof layer 270 is arranged by fixing the moisture permeable waterproof sheet 271 to the outdoor side of the sheet member 27 with a fixture such as a tacker.

The short side of the rectangular outer fireproof board 230 may be substantially aligned with the short side of the rectangular sheet member 27, but the vertical side ends 242 of the sheet members 27 adjacent to each other in the left-right direction may be overlapped with each other. Good. In this case, the thick portion 21 is formed at the overlapping portion of the vertical side end portions 242 of the sheet member 27. The dimension L2 of the thick portion 21 in the left-right direction (dimension in which the vertical side end portions 242 are overlapped with each other) can be 50 mm or more. As a result, when foaming occurs in the event of a fire or the like, gaps are less likely to occur between the left and right foaming layers, and fire resistance can be improved.

When the rectangular sheet member 27 is installed on the surface of the rectangular outer refractory board 230 in this way, the mark portion 22 provided on the rectangular sheet member 27 is attached to the outer refractory board 230 in the same manner as described above. Can be used as a guide. The adjacent positions of the sheet members 27 arranged in the left-right direction may be shifted to the left and right from the adjacent portions of the vertical support member 221 and the outer fireproof board 230 arranged in the left-right direction.

By constructing the rectangular sheet member 27 from the lower stage to the upper side, two protruding portions can be overlapped on the front side (front side). This overlapping portion is formed as a thick portion 21, and is located on the outdoor side of an adjacent portion of the rectangular outer fireproof board 230, so that the fire resistance can be improved. Further, the abutting portion of the short side of the rectangular outer fireproof board 230 and the abutting portion of the short side of the rectangular sheet member 27 may be substantially aligned in the front-rear direction, and the abutting portions may be aligned in the left-right direction. It may be misaligned.

In the above, the thick portion 21 is arranged as the high fire resistant portion 24 having higher fire resistance than the other portions at the portion corresponding to the adjacent portion of the outer fire resistant board 230 in the sheet member 27, but elements other than the thick portion 21 are arranged. May be provided as the high refractory portion 24. For example, the high fire resistance portion 24 may be a part of the seat member 27 and has higher fire resistance than the other parts. Therefore, it is sufficient that the portion corresponding to the adjacent portion of the sheet member 27 has a lower thermal conductivity than, for example, the other portion, and the portion corresponding to the adjacent portion of the sheet member 27 has a higher thermal conductivity than the other portion. A portion provided with a functional material made of a low material and provided with a functional material made of a material having a low thermal conductivity may be formed as a high fireproof portion 24. Alternatively, when the sheet member 27 is a foamed sheet material, the portion corresponding to the adjacent portion of the sheet member 27 does not have to be thicker than the other portions, and for example, it corresponds to the adjacent portion of the sheet member 27 during foaming. By configuring the ratio of the closed cells in the portion to be higher than the proportion of the closed cells in the other portions, the portion corresponding to the adjacent portion of the sheet member 27 can be formed as the highly refractory portion 24. Further, for example, the foaming ratio at a portion corresponding to the adjacent portion of the sheet member 27 may be configured to be higher than the foaming ratio at other locations.

After the functional material 20 composed of the sheet member 27 is attached to the entire surface of the base material 30, the moisture permeable waterproof sheet 65 is attached to the outdoor side of the functional material 20 in the same manner as in FIG. The moisture permeable waterproof sheet 65 is a sheet that allows moisture to pass through and does not allow water droplets to pass through. The moisture permeable waterproof sheet 65 is also attached with a fixture such as a tacker. The moisture permeable waterproof sheet 65 is attached over the entire surface of the functional material 20. A waterproof sheet that does not allow moisture or water droplets to pass through may be used.

A plurality of fasteners 80 are arranged on the outdoor side of the moisture permeable waterproof sheet 65. The fastener 80 is arranged on the outdoor side of the moisture permeable waterproof sheet 65. As a result, the plurality of fasteners 80 are arranged so as to be overlapped with the functional material 20 via the moisture permeable waterproof sheet 65. Also in the present embodiment, the support member 50 includes the fastener support member 501, and the fastener 80 is fixed to the fastener support member 501 by a fixture 86 such as a screw. Therefore, the plurality of fasteners 80 are superposed on the functional material 20 via the moisture permeable waterproof sheet 65.

Also in the present embodiment, when constructing the fastener 80, each of the plurality of fasteners 80 is arranged so that the arrangement height is within 2 mm, or is arranged so as not to overlap the thick portion 21. Therefore, the plurality of fasteners 80 are less likely to be displaced from each other in the front-rear direction.

The decorative material 10 is attached to the outdoor side of the moisture permeable waterproof sheet 65 by the fastener 80. A plurality of decorative materials 10 are arranged, and each decorative material 10 is held by a plurality of fasteners 80. The upper end of the decorative material 10 is hooked and held by the fastener 80 arranged on the upper side of the decorative material 10, and the lower end of the decorative material 10 is hooked on the fastener 80 arranged on the lower side of the decorative material 10. Be retained. Further, the decorative materials 10 adjacent to the top and bottom are connected by actual joining of the actual convex portion and the actual concave portion. Further, as in the case shown in FIGS. 4 and 10, the joint material 81 is arranged between the decorative materials 10 adjacent to each other in the left-right direction. A sealing material 83 is provided on the outdoor side of the joint material 81. A drainer 84 is provided below the lowermost decorative material 10. A ventilation layer 85 is formed on the indoor side of the decorative material 10. A ventilation layer 85 is formed between the rear surface (indoor side surface) of the decorative material 10 and the front surface (outdoor outer surface) of the moisture permeable waterproof sheet 65. Also in this embodiment, since the plurality of fasteners 80 are less likely to be displaced in the front-rear direction from each other, the decorative material 10 is also less likely to be displaced in the front-rear direction. The decrease in waterproofness between the materials 10 is unlikely to occur. Further, the workability is good when the decorative material 10 is held by the fastener 80 for construction.

It is preferable that the position of the adjacent portion of the decorative material 10 adjacent in the vertical direction and the position of the adjacent portion of the outer fireproof board 230 adjacent in the vertical direction are shifted so as not to overlap in the front view. Further, it is preferable that the joints of the adjacent decorative material 10 and the joints of the adjacent outer fireproof board 230 are shifted so as not to overlap each other in the front view. That is, it is preferable that the position of the sealing material 83 between the decorative materials 10 adjacent in the left-right direction and the position of the adjacent portion of the outer fireproof board 230 adjacent in the left-right direction are shifted so as not to overlap each other in the front view. In this case, even if a flame invades the joint and the adjacent portion of the adjacent decorative material 10 from the outdoor side, it becomes difficult for the flame to directly invade the joint and the adjacent portion of the adjacent outer fireproof board 230, and the fire resistance is improved. Can be made to. It is preferable that the joints of the decorative material 10 adjacent to each other in the left-right direction and the vertical side abutting portion of the outer fireproof board 230 adjacent to the left-right direction coincide with the vertical support material 221 in the front view. The vertical side abutting portion may be matched with the same vertical support member 221, or the joint and the vertical side abutting portion may be matched with a different vertical support member 221.

A runner 222 and a plurality of inner vertical support members 223 are arranged on the indoor side of the vertical support member 221. Of the runners 222, the upper runner is arranged on the ceiling surface and the lower runner 225 is arranged on the floor surface. The upper end of each inner vertical support member 223 is inserted into and held by the upper runner. The lower end of each inner vertical support member 223 is inserted and held in the lower runner 225. Then, a plurality of inner refractory boards 210 are fixed to at least one of the runner 222 and the plurality of inner vertical support members 223 by fixing tools 224 such as screws or nails. The plurality of inner refractory boards 210 are arranged side by side in the vertical direction and the horizontal direction. The ends of the inner refractory boards 210 adjacent to each other in the vertical direction and the horizontal direction are arranged so as to abut each other. The upper runner may be fixed to the ceiling surface or may be fixed to the vertical support member 221. The lower runner may be fixed to the floor surface or may be fixed to the vertical support member 221.

In the functional material construction structure 1 formed as described above, the same effects as those in the first and second embodiments can be obtained. That is, in the functional material construction structure 1, if the functional material 20 is a particularly refractory material and the sheet member 27 is a particularly heat-foamable sheet 240, it is heated from the outdoor side of the decorative material 10 in the event of a fire. Then, the heat-foamable sheet 240 foams and expands to form a foam layer in the ventilation layer 85. The ventilation layer 85 is used as a foaming space 88 for the heat-foamable sheet 240 to foam and expand. Thereby, due to the heat-shielding effect and the flame-shielding effect of the foamed and expanded heat-foamable sheet 240, it is possible to reduce the invasion of flame and heat from the outside to the inside, and therefore, the fire resistance can be improved. At the same time, the foamed and expanded heat-foamable sheet 240 does not form a space that communicates vertically between the decorative material 10 and the outer fireproof board 230, and heat is generated in the vertical direction between the decorative material 10 and the outer fireproof board 230. It can be suppressed to move to. Further, by providing the heat-foamable sheet 240 behind the decorative material 10, high weather resistance and water resistance are not required for the heat-foamable sheet 240, and fire resistance can be improved. Further, since the heat-foamable sheet 240 is a thin material if there is no fire, it does not normally hinder the ventilation layer 85, and the dimensions of the functional material construction structure 1 in the front-rear direction (from the decorative material 10 to the outer fireproof board 230). Dimension) is unlikely to be larger than the conventional one. Further, since the heat-foamable sheet 240 is relatively lighter than the outer fireproof board 230, the burden during construction can be reduced. Further, in the functional material construction structure 1, by providing the heat-foamable sheet 240, in the event of a fire, the heat-foamable sheet 240 is heated from the indoor side of the inner refractory board 210, and the heat-foamable sheet 240 foams and expands. A foam layer is formed in the ventilation layer 85. As a result, it is possible to reduce the release of flames and heat from indoors to outdoors due to the heat-shielding effect and the flame-shielding effect of the foamed and expanded heat-foamable sheet 240, and therefore, it is possible to improve the fire resistance. it can.

Further, in the third embodiment, the heat insulating material 40 is not provided, but the present invention is not limited to this, and the heat insulating material 40 may be provided.

Further, in the first to third embodiments, as shown in FIG. 6, for example, the adjacent portion 32 in the left-right direction of the base member 35 coincides with the support member 50, but the adjacent portion 32 is not limited to this. It does not have to match the support material 50. In this case, the portion of the functional material 20 corresponding to the adjacent portion 32 may be formed thicker than the other portion of the functional material 20.

Further, in the first to third embodiments, the "horizontal" structure is provided so that the longitudinal direction of the decorative material 10 is horizontal, but the present invention is not limited to this, and the longitudinal direction of the decorative material 10 is vertical. It may be a "vertical" structure provided so as to be. When the above embodiment has a roof structure, the decorative material may be a roofing material and may have either a horizontal roofing structure or a vertical roofing structure.

Further, in the first to third embodiments, after the plurality of base members 35 are constructed to form the base material 30, the plurality of sheet members 27 are constructed to form the functional material 20, but the present invention is not limited to this. After the base member 35 and the sheet member 27 are integrated in advance (before construction) to form the base member 36 with a sheet, a plurality of base members 36 with a sheet may be constructed.

13A and 13B show an example of the base member 36 with a sheet. The base member 36 with a sheet is provided with a horizontally long rectangular sheet member 27 similar to the above on one side (surface) of the horizontally long rectangular base member 35 similar to the above. The left-right dimension of the base member 35 and the left-right dimension of the sheet member 27 are the same. In the front view, the left end of the base member 35 and the left end of the sheet member 27 coincide with each other, and the right end of the base member 35 and the sheet member. It coincides with the right end of 27. The vertical dimension of the sheet member 27 is formed longer than the vertical dimension of the base member 35. The tip of the upper end portion 26a of the sheet member 27 projects upward from the upper end surface of the base member 35. The tip of the lower end portion 26b of the sheet member 27 projects below the lower end surface of the base member 35. The surface of the base member 35 and the sheet member 27 are adhered to each other over almost the entire surface, but as shown in FIG. 13A, the lower portion of the surface of the base member 35 and the lower end portion 26b of the sheet member 27 are formed so as to be peelable. ing.

The base material 30 and the functional material 20 similar to the above are formed by arranging a plurality of base members 36 with sheets in the vertical direction and the horizontal direction and attaching them to the support material 50 as shown in FIG. 13C. That is, the base material 30 is formed by the plurality of base members 35, and the functional material 20 is formed by the plurality of sheet members 27. A thick portion 21 of the functional material 20 is formed corresponding to the adjacent portion 31 of the base member 35 adjacent in the vertical direction. The thick portion 21 is formed by overlapping the upper end portion 26a of the sheet member 27 of the lower sheet-attached base member 36 and the lower end portion 26b of the sheet member 27 of the upper sheet-attached base member 36. That is, after the upper end of the lower base member 35 and the lower end of the upper base member 35 are abutted against each other, the lower end portion 26b of the upper sheet member 27 is peeled off from the surface of the upper base member 35, and then next. The upper end portion 26a of the lower sheet member 27 is inserted between the lower portion of the upper base member 35 and the lower end portion 26b of the upper sheet member 27. After that, the lower end portion 26b of the upper sheet member 27 is overlapped with the upper end portion 26a of the lower sheet member 27. In this way, the thick portion 21 is formed by overlapping the upper end portion 26a and the lower end portion 26b of the two sheet members 27. In the portion corresponding to the adjacent portion 32 of the base member 35 adjacent in the left-right direction, the side end portions of the sheet members 27 adjacent in the left-right direction are adjacent to each other.

In this example, the thick portion 21 has only the double-layered portion 212 due to the overlap of the upper end portion 26a and the lower end portion 26b. In this example, the horizontal dimension of the sheet member 27 may be larger than the horizontal dimension of the base member 35. In this case, the side ends of the sheet members 27 adjacent to each other in the left-right direction overlap each other, so that the thick portion 21 is also formed corresponding to the adjacent portion 31 of the base member 35 adjacent to the left-right direction. The meat portion 21 has a double-layered portion 212 and a four-layered portion 214, as in the case shown in FIG. When attaching the plurality of fasteners 80, each of the fasteners 80 is arranged so that the arrangement height is within 2 mm, or is arranged so as not to overlap the thick portion 21.

FIG. 14A shows another example of the base member 36 with a sheet. Compared with those in FIGS. 13A and 13B, the sheet member 27 is displaced in one of the left-right directions with respect to the base member 35. That is, for example, the right end portion of the sheet member 27 projects laterally (outside) from the right end surface of the base member 35 as a covering portion 28. Therefore, the left end portion of the surface of the base member 35 is formed as a covering portion 37 that is not covered with the sheet member 27. On the contrary, the left end portion of the sheet member 27 protrudes laterally (outside) from the left end surface of the base member 35 as a covering portion 28, and the right end portion of the surface of the base member 35 is not covered with the sheet member 27. It may be formed as a portion 37.

As shown in FIG. 14B, such a base member 36 with a sheet is installed by arranging them in the vertical direction and the horizontal direction and attaching them to the support member 50 in the same manner as described above. Then, similarly to the above, the upper end portion 26a of the sheet member 27 of the lower sheet-attached base member 36 and the lower end portion 26b of the sheet member 27 of the upper sheet-attached base member 36 are overlapped with each other so as to be adjacent in the vertical direction. A thick portion 21 of the functional material 20 is formed corresponding to the adjacent portion 31 of the base member 35 to be formed.

Further, the base member 36 with a sheet adjacent in the left-right direction is constructed by abutting the side ends of the base member 35 with each other. At this time, one base member 35 is constructed with the side end of the covering portion 28 protruding. The other base member 35 is a side end portion on the covering portion 37 side. Then, after the side ends of the base member 35 are abutted against each other, the covering portion 28 of the base member 36 with a sheet is arranged on the surface of the covering portion 37 of the base member 36 with a sheet of the other. In this case, the adjacent position (boundary) 29 of the seat member 27 adjacent in the left-right direction and the adjacent portion 32 do not match in the front view, and the two are displaced in the left-right direction. Therefore, the portion corresponding to the adjacent portion 32 of the base member 35 adjacent in the left-right direction is covered with the covering portion 28 of the sheet member 27, and flames and heat are less likely to enter through the gap of the adjacent portion 32.

Also in this example, the thick portion 21 has only the double-layered portion 212 due to the overlap of the upper end portion 26a and the lower end portion 26b. In this example as well, the horizontal dimension of the sheet member 27 may be larger than the horizontal dimension of the base member 35. In this case, the thick portion 21 is also formed by overlapping the side ends of the sheet members 27 adjacent to each other in the left-right direction. Therefore, the thick portion 21 is formed with the double-layered portion 212 as in the case shown in FIG. It has a four-layered portion 214. When attaching the plurality of fasteners 80, each of the fasteners 80 is arranged so that the arrangement height is within 2 mm, or is arranged so as not to overlap the thick portion 21.

When the base member 36 with a sheet is used, the base member 35 and the sheet member 27 can be constructed at the same time in one operation, and the workability is improved. Further, it is not necessary to separately pack and transport the base member 35 and the sheet member 27, which improves workability.

(2) Functional Material In each of the above embodiments, the thick portion 21 of the functional material 20 is the upper end portion and the upper sheet of the lower sheet member 27 of the two sheet members 27 adjacent in the vertical direction. It may be formed only by overlapping with the lower end portion of the member 27, and in this case, as shown in FIG. 8B, for example, the sheet members 27 adjacent to each other in the left-right direction may be abutted at an adjacent position (boundary) 29. .. Further, the thick portion 21 may be formed only by overlapping the side end portions of the two sheet members 27 adjacent to each other in the left-right direction, and in that case, the sheet members 27 adjacent to each other in the vertical direction may be formed at adjacent positions (in this case). They may be butted at the boundary). In any of the above cases, the thick portion 21 has a double-layered portion 212. Further, as shown in FIGS. 1, 2 and 15, the thick portion 21 is the upper end portion of the lower sheet member 27 and the upper sheet member 27 of the two sheet members 27 adjacent to each other in the vertical direction. By being formed by both the overlap with the upper end portion of the sheet and the overlap between the side ends of the two sheet members 27 adjacent to each other in the left-right direction, the double-layered portion 212 and the triple-layered portion 213 or four sheets are formed. It may have an overlapping portion 214. The sheet members 27 may be overlapped in various modes other than the above. In any case, when attaching the plurality of fasteners 80, each of the fasteners 80 is arranged so that the arrangement height is within 2 mm, or is arranged so as not to overlap the thick portion 21. ..

The thick portion 21 can have both an arrangement portion and a portion having a thickness larger than the arrangement portion. Further, the thick portion 21 may have only the arrangement portion, that is, the thick portion 21 may have a thickness equal to or less than the thickness defining the arrangement portion as a whole. For that purpose, when constructing the sheet member 27 and forming the thick portion 21 by stacking the sheet members 27, the upper limit of the number of sheets to be stacked is the upper limit of the number of sheets to be stacked, and the thickness of the thick portion 21 is arranged as a whole. It may be regulated so that the thickness is less than or equal to the specified thickness of the portion. In this case, the plurality of fasteners 80 may be arranged at positions overlapping any portion of the functional material 20. Further, the thick portion 21 does not have to have an arrangement portion. That is, the thick portion 21 may have a thickness larger than the thickness defining the arrangement portion as a whole. In this case, all of the plurality of fasteners 80 are arranged so as not to overlap the thick portion 21.

Further, on the sheet member 27, not only the mark portion 22 formed long and linearly in the left-right direction to indicate the horizontal position, but also the mark formed long linearly in the vertical direction so as to indicate the vertical position. A part may be provided.

In the present embodiment, a fireproof sheet (heat foamable sheet) having fire resistance is described as the sheet member 27 constituting the functional material 20, but the present invention is not limited to this, and for example, a ventilation waterproof sheet, etc. It may be a functional sheet other than the fireproof sheet, such as a waterproof sheet, a heat shield sheet, or a sound insulation sheet.

(3) Support Material The support material 50 may have a vertical furring strip that is long in the vertical direction or a horizontal furring strip that is long in the horizontal direction.

In the present embodiment, the support member 50 includes the fastener support member 501 that supports the fastener 80, but may not include the fastener support member 501. That is, the fastener 80 may be supported by a member other than the support member 50. Further, the support member 50 may include only the fastener support member 501.
