Description

  The present invention relates to a seal structure in which two members forming an exterior part of a building are connected by a combination of a dry sealing material and a wet sealing material.

  Two members that form the exterior part of a building, for example, a wet structure by a wet construction method in which a wet sealing material is placed on a joint part as a seal structure applied to a joint region between two exterior panel members arranged opposite to each other A seal structure and a dry seal structure by a dry construction method in which a dry sealant (for example, a dry gasket) is attached to a joint portion are generally known. However, the wet method depends on the weather and takes a long period of time. On the other hand, the dry method is difficult to ensure complete waterproofing with only the dry sealant. Therefore, it is necessary to consider a double waterproof structure by putting a waterproof sheet on the base, which is expensive and has a drawback that it is difficult to replace an aged waterproof sheet.

  Therefore, in order to solve the disadvantages of the above methods, for example, as described in Patent Document 1, a seal structure formed by a mixed method using a wet sealing material and a dry sealing material in combination is known.

  Since the dry sealant is likely to have lower sealability and deformation followability than the wet sealant, the conventional seal structure in which the dry sealant is exposed from the surface makes it difficult to stably maintain the sealability. The design properties were also easily lowered by the exposed dry sealant.

  An object of this invention is to provide the sealing structure which can maintain a sealing performance stably and can improve the designability.

  One embodiment of the present invention is a seal structure in which two members forming an exterior part of a building are connected by a combination of a dry sealant and a wet sealant, and the dry sealant is between two members. It is arranged in the gap area to be formed and is fixed to at least one of the two members, and the wet sealing material is fixed to the dry sealing material in the gap area and the surface side of the exterior part In Fig. 1, the dry sealing material is covered and reaches the bottom of the dry sealing material in the depth direction of the gap region.

  In this seal structure, the wet sealing material fixed to the dry sealing material covers the dry sealing material on the surface side of the exterior portion, so that intrusion of rainwater and the like from the outside can be effectively prevented. Furthermore, the wet sealant reaches the bottom of the dry sealant in the depth direction of the gap region. Therefore, the combined seal area produced by the cooperation of the dry sealant and the wet sealant is wider in the depth direction than when the wet sealant does not reach the bottom, and the sealing performance is stabilized. It is advantageous to maintain. Furthermore, since the wet sealant covers the dry sealant, the dry sealant fixed to one member is substantially blinded, which is advantageous in improving the design.

  Moreover, in the said aspect, two members are exterior panel materials, A clearance gap area | region can be made into the joint area formed by opposing arrangement | positioning of two exterior panels. In this aspect, the sealability in the joint area can be stably maintained, and the design property can be improved.

  Further, in the above aspect, one member to which the dry sealing material is fixed is an exterior panel material, the other member is an incidental member disposed in an opening provided in the exterior panel material, and the gap region is defined by the exterior panel. It can be a gap space formed between the opening and the incidental member. In this aspect, the sealing property in the gap space can be stably maintained, and the design property can be improved.

  Furthermore, the modulus of the dry sealing material and that of the wet sealing material are preferably in the same category, and are preferably the same material. In this aspect, the load such as compression or tension caused by the relative displacement between the two members can be equalized between the dry sealing material and the wet sealing material, and the followability to the relative displacement can be improved.

  In addition, by making the wet sealant and one member to which the dry sealant is fixed the same color, it is possible to produce a sense of unity between the dry sealant and the one member, It is difficult to recognize the difference in fine patterns, which is advantageous for improving the design.

  In addition, the wet sealing material has a surface layer portion that covers the surface side of the dry sealing material, and a depth portion that reaches the bottom of the dry sealing material along the side surface of the dry sealing material, and the depth of the depth portion is It is preferable that the length is larger than the length corresponding to the thickness of the surface layer portion. The combined seal area produced by the cooperation of the depth portion and the dry sealant can be widened, which is advantageous in stably maintaining the sealing performance.

  Further, the dry sealing material has an inclined surface inclined from the surface side of the exterior part to the bottom of the dry sealing material, and the wet sealing material is fixed to the inclined surface and is wide on the surface side of the exterior part, and on the bottom side. It is preferable that the diameter is gradually reduced so as to be narrow. For example, when the wet sealing material is filled from the surface side of the exterior portion and disposed in the gap region, the wet sealing material smoothly reaches the bottom while being guided by the inclined surface of the dry sealing material. As a result, it is difficult to produce a poorly fixed portion between the wet sealing material and the dry sealing material, which is advantageous in maintaining the stability of the sealing performance.

  In particular, if the inclined surface of the dry sealant has a convex shape, when placing the wet sealant, it becomes easier for the wet sealant to reach the bottom of the dry sealant, which improves the stability of the sealing performance. It is advantageous to maintain.

  In addition, it is preferable that the dry sealing material has a fixing surface that is fixed to the wet sealing material and the fixing surface has an uneven shape because the surface area fixed to the wet sealing material can be increased.

  Each of the two exterior panel members has a joint groove that forms a joint region by opposing arrangement, and an air vent gap is formed between the bottoms of the joint grooves arranged opposite to each other. It is preferable that the air gap is reached. The fact that the wet sealant reaches the air gap means that the air is smoothly removed from the gap when the wet sealant is placed, and therefore the wet sealant due to residual air. Inadequate adhesion between the sealant and the dry sealant is unlikely to occur, which is advantageous in maintaining the stability of the sealing performance.

  According to the present invention, the sealing property can be stably maintained and the design property can be improved.

In the following description, the same reference numerals are used for the same elements or elements having the same functions, and repeated descriptions are appropriately omitted.

  The outer wall W (see FIG. 1) includes a plurality of outer wall panels 1A arranged side by side, or the outer wall panel 1A is provided vertically and horizontally adjacent to a window frame 1B (see FIG. 8) such as an open sash frame. Formed with. The planar members that form the outer wall W such as the outer wall panel 1A and the window frame 1B correspond to exterior panel materials. Here, as the outer wall panel 1A, a precast reinforced concrete (PC) plate, a lightweight cellular concrete (ALC) plate, a metal curtain wall, or the like can be used. In the following embodiments, an outer wall panel assuming an ALC panel is used. 1A will be described as an example.

[First Embodiment]
As shown in FIG. 1 and FIG. 2, a joint region A is formed between a pair of (two) adjacent outer wall panels 1 </ b> A by arranging a plurality of outer wall panels 1 </ b> A in a standing manner. The Specifically, joint grooves 2A are formed in the side end face 1a of the outer wall panel 1A along the longitudinal direction of the side end face 1a. The joint grooves 2A are formed so as to cut out the corners on the outdoor side of the side end face 1a, and the joint grooves 2A are arranged opposite to each other by the opposing arrangement of the side end faces 1a, and between the joint grooves 2A facing each other A joint region A is formed at the end. In the following description, the “surface side” is assumed to be the side of the outer wall W facing the outdoors (the surface side of the exterior part), and particularly the side where the joint region A is formed.

  The joint groove 2 </ b> A includes a side surface portion 21 </ b> A and a bottom surface portion 22, and a region formed by the pair of opposing side surface portions 21 </ b> A and the pair of bottom surface portions 22 becomes the joint region A. The pair of side surface portions 21 </ b> A has a symmetrical shape with the pair of bottom surface portions 22 sandwiched therebetween, and a vertical surface 21 b that rises substantially perpendicular to the bottom surface portion 22, and a joint area from the vertical surface 21 b to the surface Sf of the outer wall W. And an inclined surface 21a inclined so as to increase the width of A. Of the joint area A, the area sandwiched between the pair of vertical surfaces 21b is the joint water stop area Aa, and the area sandwiched between the pair of inclined surfaces 21a is the joint design area Ab.

  The seal structure 10A according to the present embodiment is a structure in which a dry sealing material 3A and a wet sealing material 5A are used in combination for water stoppage of the joint region A, and a pair of outer wall panels 1A arranged in parallel are used in combination. The dry sealant 3A and the wet sealant 5A are connected. The combined use of the dry sealant 3A and the wet sealant 5A will be described in more detail.

  In the joint water stoppage area Aa, a dry sealing material 3A having a rectangular cross section is fixed (fixed) to the vertical surface 21b and the bottom surface portion 22 of the joint groove 2A. Specifically, primer treatment is applied to the vertical surface 21b and the bottom surface portion 22 of the joint groove 2A, and an adhesive is further applied. The dry sealant 3 </ b> A is a long member formed in accordance with the longitudinal dimension of the joint region A, and is bonded to the vertical surface 21 b and the bottom surface portion 22 to which an adhesive is applied. The construction of the dry sealing material 3A is not performed at the site where the outer wall W is provided, but at a site other than the site, such as a factory. By constructing the dry sealing material 3A in advance at a place other than the site, it is possible to improve the adhesion reliability as compared with the case of construction at the site.

  In the joint water stoppage area Aa, there is a slight gap (for example, about 1 mm in width) between the pair of bottom surface portions 22, and the pair of dry sealing materials 3 </ b> A are arranged to face each other with the gap S interposed therebetween. ing. The wet sealant 5 </ b> A is filled between the pair of dry sealants 3 </ b> A, and the air in the joint water stop area Aa is pushed out from the gap S between the bottom portions 22. As a result, the wet sealant 5A smoothly reaches the bottom 3a of the dry sealant 3A. Further, the wet sealing material 5A covers the surface layer Sa of the joint water-stopping region Aa and covers the dry sealing material 3A. The wet sealing material 5A filled in the joint water stop region Aa is finished to a smooth surface while being pressurized with a spatula or the like.

  The dry sealing material 3A includes a fixing surface 30 that is fixed to the wet sealing material 5A. The fixing surface 30 includes a surface-side fixing surface 3b that is fixed to the surface layer portion 5a of the wet sealing material 5A, and a depth-side fixing surface 3c that corresponds to the side surfaces facing each other. The surface-side fixing surface 3b and the depth-side fixing surface 3c are substantially flat surfaces in consideration of easy escape of air when filling the wet sealing material 5A.

  The wet sealant 5A cures in a state where the space in the joint water stop area Aa is filled, and connects the opposite dry sealants 3A. The cured wet sealing material 5A is substantially T-shaped in a cross-sectional view and includes a surface layer portion 5a and a depth portion 5b. The surface layer portion 5a is fixed to the surface layer side fixing surface 3b while covering the surface layer side fixing surface (surface) 3b of the dry sealant 3A. Further, the depth portion 5b reaches the bottom portion 3a of the dry sealing material 3A along the depth side fixing surface (side surface) 3c of the dry sealing material 3A, and is fixed to the depth side fixing surface 3c in a wide range.

  The surface side fixing surface 3b of the dry sealing material 3A according to the present embodiment is along the virtual surface layer Sa of the joint water-stopping region Aa, and as a result, wet sealing that covers the surface layer Sa of the joint water-stopping region Aa. The thickness of the surface layer portion 5a of the material 5A is substantially constant. And length Db used as the depth of the depth part 5b of 5 A of wet sealing materials is larger than length Da used as the thickness of the surface layer part 5a. Specifically, the length Db that is the depth of the depth portion 5b is, for example, preferably not less than twice the length Da that is the thickness of the surface layer portion 5a, and is preferably not more than 5 times.

  The surface Sf on which the outer wall panel 1A is coated and the wet sealant 5A are preferably the same color. The system color is a color name that allows the object colors to be systematically classified and expressed, for example, three types of white, gray, and black for an achromatic color, and red, yellow, green, for a chromatic color, It is classified into blue, purple, and 10 kinds such as yellow-red, yellow-green, blue-green, blue-violet, and red-purple, which are intermediate colors.

  That is, if the surface Sf on which the outer wall panel 1A is coated is a single color finish, the wet sealant 5A is preferably a single color similar to the outer wall panel 1A (same system color). In addition, if the surface Sf on which the outer wall panel 1A is coated has a colorful pattern, the wet sealant 5A is preferably a multicolored sealant (various sealing material) similar to the outer wall panel 1A. By making the surface Sf of the outer wall panel 1A and the wet sealing material 5A the same color, and making the same multicolored pattern, the wet sealing material 5A can be made inconspicuous with respect to the outer wall panel 1A. It is advantageous for improvement.

  FIG. 3 shows an example of the outer wall panel 1A having a colorful pattern. The multicolored pattern is a pattern in which two or more colors are used, and a pattern form in which each color is irregularly arranged is particularly preferable. In FIG. 3, a black or blackish gray portion and a gray portion indicate colored mixed particles of the multicolored paint, and a white portion indicates an uncolored region. As described above, the colored mixed grains are randomly sprayed on the surface Sf of the outer wall panel 1A. The multicolored paint is obtained by dispersing several kinds of colored paints having different colors as liquids or gel-like mixed liquids (colored mixed grains) of various sizes in a dispersion medium in a state where they are not dissolved in each other. As such a colorful pattern paint, an oil-in-water type and water-in-oil type colorful pattern paint in which one of the colored mixed particles and the dispersion medium is an oily system and the other is an aqueous system, and an underwater system in which both are the same system There are water-type and oil-in-oil type colorful paints. The coating for making the surface Sf of the outer wall panel 1A into a colorful pattern is formed, for example, by spraying a colorful pattern paint using a spray gun in a factory.

  As the wet sealant 5A, a generally circulating sealant can be appropriately selected and used according to the material of the outer wall panel 1A. Here, when the outer wall panel 1A is an ALC panel as in the present embodiment, the modified silicone type, acrylic urethane type, polyurethane type, which are rich in flexibility and hardly cause destruction of the base material when deformed by an external force such as an earthquake. A sealing material such as is preferable. On the other hand, as the dry sealing material 3A, a material obtained by curing a modified silicone type, acrylic urethane type, polyurethane type sealing material or the like can be used. In particular, the wet sealing material 5A and the dry sealing material 3A are the same material. can do. Further, the dry sealing material 3A can be formed of rubber such as EPDM rubber or urethane rubber, which is completely different from the wet sealing material 5A, and a foam thereof.

Further, the dry sealing material 3A and the wet sealing material 5A preferably have the same modulus. Modulus and is the stress that acts when given a constant strain in the elastic body, segment modulus is less than 0.2 N / mm ² is low modulus, 0.2 N / mm ² or more, 0.4 N Less than / mm ² is a medium modulus, and 0.4 N / mm ² or more is a high modulus. It is preferable that both the dry sealing material 3A and the wet sealing material 5A according to the present embodiment have a low modulus.

  In addition, as FIG. 4 shows, it is also possible to set it as the seal structure 10A which concerns on a 1st modification. In the seal structure 10A according to the first modified example, the fixing surface 30 of the dry sealing material 3A has an uneven shape R, and the surface area in close contact with the wet sealing material 5A is increased to increase the adhesion. In the seal structure 10A according to the first modified example, in consideration of the ease of air removal when filling the wet sealing material 5A, only the surface-side fixing surface 3b has an uneven shape R, but the depth-side fixing surface It is also possible to make the uneven shape R 3c. In addition, when the surface layer side fixed surface 3b is uneven | corrugated shape R, the thickness of the surface layer part 5a of 5A of wet sealing materials may change with places. In this case, it is preferable that the length Db (see FIG. 2) which is the depth of the depth portion 5b is larger than the length Da of the thickest portion of the surface layer portion 5a.

  In the case of the seal structure 10A according to the first modification, it is also possible to dispose the top of the concavo-convex shape R formed on the surface layer-side fixing surface 3b so as to overlap the surface layer surface Sa of the joint water stop region Aa. is there. If it is this aspect, since the wet sealing material 5A can be filled with the top part of the uneven | corrugated shape R as a standard, the finishing process of the surface layer surface Sa of the joint water stop area | region Aa becomes easy, and the design property improves. In the state where the top of the uneven shape R of the dry sealing material overlaps the surface layer Sa of the joint water-stopping region Aa, the wet sealing material 5A is substantially dry-sealed on the surface Sf side of the outer wall panel 1A. In this state, the material 3A is covered.

It is also possible to make the thickness of the surface layer portion 5a of the wet sealing material 5A fixed to the inside deeper at the inner side connected to the depth portion 5b and shallower at the outer side. In the seal structure 10A according to the second modified example, when the wet sealing material 5A is filled, it is guided by the inclination of the surface-layer-side fixing surface 3b and smoothly enters between the dry sealing materials 3A to form the depth portion 5b. . In addition, it is also possible to reverse the height of the inclination of the surface side fixing surface 3b so that it is deep on the outside and shallow on the inside.

  In addition, when the building has two or more levels and the outer wall panel 1A is continuously provided in the vertical direction, the vertical joint area A and the horizontal joint are formed in a cross shape or a T shape. At the intersection of the region A (including the connection portion in the case of T-shape), one or both of the dry sealants 3A are stopped before the intersection so that the dry sealants 3A do not cross each other. preferable. The shape of the end portion of the dry sealing material 3A stopped before the intersection can be arbitrarily determined, but it is preferable to process it diagonally so that the thickness gradually decreases.

  In the seal structures 10A to 10F according to each of the above embodiments, the wet sealing materials 5A to 5F cover the dry sealing materials 3A to 3F on the surface Sf side of the outer wall panel 1A or the window frame 1B. Intrusion can be effectively prevented. Further, the wet sealing materials 5A to 5F reach the bottom 3a of the dry sealing materials 3A to 3F in the depth direction of the joint region A and the gap space B. Therefore, the combined seal region produced by the cooperation of the dry sealing materials 3A to 3F and the wet sealing materials 5A to 5F is directed in the depth direction as compared with the case where the wet sealing materials 5A to 5F do not reach the bottom 3a. This is advantageous in stably maintaining the sealing performance of the joint region A and the gap space B. Furthermore, the wet sealing materials 5A to 5F cover the dry sealing material 3F, thereby substantially concealing the dry sealing material 3F, which is advantageous in improving the design.

  Furthermore, by making the modulus of the dry sealing materials 3A to 3F and the wet sealing materials 5A to 5F into the same section or the same material, the outer wall panels 1A, the outer wall panel 1A and the window frame 1B, or the outer wall panel The load such as compression or tension caused by the relative displacement between 1A and the pipe (attachment member) 9 can be equalized between the dry sealing materials 3A to 3F and the wet sealing materials 5A to 5F, and the followability to the relative displacement is improved. be able to. As a result, an excessive load is applied to any one of the dry sealing materials 3A to 3F and the wet sealing materials 5A to 5F, and as a result, it is possible to prevent damage and the like from being deteriorated in sealing performance. Moreover, it becomes easy to improve the adhesiveness of dry type sealing materials 3A-3F and wet sealing materials 5A-5F by using the same material.

  Also, the wet sealing material 5A to 5F and the outer wall panel (one member) 1A to which the dry sealing materials 3A to 3F are fixed have the same color so that the dry sealing material 3F and the outer wall panel 1A have a sense of unity. It is possible to produce a variety of patterns, and it is difficult to recognize fine pattern differences, which is advantageous for improving the design.

  Further, the wet sealing materials 5A, 5C, and 5D according to the first embodiment, the third embodiment, and the fourth embodiment include the surface layer portion 5a and the depth portion 5b, and the length Db that is the depth of the depth portion 5b is The length Da is the thickness of the surface layer portion 5a. As a result, it is possible to widen the combined seal region produced by the cooperation of the depth portion 5b and the dry sealants 3A, 3C, and 3D, which is advantageous in stably maintaining the sealing performance.

  Further, the dry sealing materials 3B and 3E according to the second embodiment and the fifth embodiment have a fixing surface 31 inclined from the surface layer surface Sa side to the bottom portion 3a of the joint water-stopping region Aa, and the wet sealing material 5B, 5E is gradually reduced in diameter so that it is wide on the surface layer Sa side and narrows on the bottom 3a side of the dry sealing materials 3B and 3E. In these forms, for example, when the wet sealing materials 5B and 5E are filled from the surface layer Sa side and arranged in the joint region A, the wet sealing materials 5B and 5E are fixed surfaces 31 of the dry sealing materials 3B and 3E. Smoothly reach the bottom while being guided by. As a result, it is difficult to produce a poorly fixed portion between the wet sealing materials 5B and 5E and the dry sealing materials 3B and 3E, which is advantageous in maintaining the stability of the sealing performance.

  Further, in the seal structures 10A, 10B, and 10C according to the first to third embodiments, joint grooves 2A that form joint regions A are formed in the opposing outer wall panels 1A, respectively, and between the bottom portions 3a of the joint grooves 2A. Is formed with an air vent gap S. The wet sealing materials 5A, 5B, and 5C reach the air vent gap S. Further, in the seal structures 10D and 10E according to the fourth and fifth embodiments, joint grooves 2A and 2B that form joint regions A are formed in the facing outer wall panel 1A and the window frame 1B, and the joint grooves 2A and 2B are formed. An air vent gap S is formed between the bottoms 3a. The wet sealing materials 5D and 5E reach the air vent gap S. Here, the fact that the wet sealing materials 5A to 5E have reached the clearance S of the air vent means that air is smoothly removed from the clearance S when the wet sealing materials 5A to 5E are arranged. Therefore, poor adhesion between the wet sealing materials 5A to 5E and the dry sealing materials 3A to 3E due to residual air hardly occurs, which is advantageous in maintaining the stability of the sealing performance.
