Description

  The present invention relates to a wooden or steel frame construction method, an architectural panel capable of covering the entire indoor space of a building and constructing a wall surface, a ceiling surface, a floor surface, and a roof surface, and a shaft using the same. The present invention relates to a method for constructing a set structure.

  Conventionally, among building panels to be inserted between columns in a wooden frame construction method, a building panel that is easily standardized and a construction method for a wooden house using the panel have been proposed (Patent Document 1). In addition, the construction period of the frame building is shortened, the waste on the construction site is reduced, and the walls of strength, durability, heat insulation, airtightness, design, etc. are required without the need for penetration, streaking, and waistline. A laminated wall true wall panel structure of a framed building that can function and use thinned wood has been proposed (Patent Document 2).

JP 2003-313941 A JP 2002-256636 A

  However, the building panel described in Patent Document 1 incorporates a frame material on one surface side of the structural plywood and, if necessary, a stud or a trunk edge inside the frame material, fills the frame material with a heat insulating material, and It is a structural panel for wall ceiling characterized in that it is entirely covered with an interior base plate, and the edge of the structural plywood protrudes or retracts from the outer peripheral surface of the frame material in accordance with a predetermined installation location. . In addition, the construction method of a wooden house using this building panel is that the projecting edge of the building panel is a structure such as a pillar or beam, an adjustment square attached to the structure, or the receding edge of an adjacent panel. This is a construction method of a wooden house, characterized in that the roof assembly and the interior partition wall are constructed by appropriate means. For this reason, the building panel uses a relatively expensive frame material, a pillar, and a body edge, which are usually used, and there is a problem that the cost is high, and the pillar and the body edge are incorporated. Therefore, there is a tendency to be weak against the compressive force in the thickness direction of the panel applied to the part without the studs and torso, and the resistance of the building panel to shear deformation may not be sufficient. There is a problem that the seismic performance may not be sufficiently improved.

  Moreover, the laminated wall true wall panel structure of the frame building described in Patent Document 2 is made by joining the plate members in the vertical direction and in the direction perpendicular to the horizontal landscape, and incorporating them between the frame frames of the frame building. Because of the laminated wall structure of the laminated timber that constitutes the wall, the amount of plate material used is very large, which increases the weight of the panel and requires excessive labor for transportation and integration between columns. is there.

  In addition, the construction method of the building panel and the wooden house described in Patent Document 1 covers the entire indoor space of the building except the roof and the back of the hut with the building panel (described in paragraph 0007 of the specification). Because the laminated wall structure of a laminated building of a framed building described in 2 relates to the walled wall panel structure incorporated between the framed frames of the framed building, there is a problem that they cannot be applied to the roof part or the back of the shed. There is a problem that it is impossible to effectively prevent contamination of the building from the radioactive material leaked from the nuclear accident or the like by constructing the building panel or the true wall panel on the roof portion.

  The problem to be solved by the present invention is not only in-plane compressive force but also sufficient resistance to shear deformation of the panel, and as a result, the seismic performance of the frame building is sufficiently improved. In addition to providing a construction panel that can be manufactured at low cost by using low-priced thinned wood and a method for constructing a frame structure using the panel, the entire frame structure also has a roof part. Since it can be covered with the building panel, it can effectively prevent radioactive contamination inside the building due to radioactive material leaked due to a nuclear accident, etc., and a frame structure using the same It is to provide a construction method.

  The invention according to claim 1 is a building panel in which a rectangular frame is formed by a vertical frame material and a horizontal frame material, and both sides of the rectangular frame are covered with a surface material, and an edge of the surface material on one surface is formed. Protruding from the outer peripheral surface of the rectangular frame, the edge of the face material on the other surface is formed so as to be flush with or receding from the outer peripheral surface of the rectangular frame, and a plurality of plates are crossed inside the rectangular frame to form an oblique lattice The crossing part of the plate material is fixed to the end face of the plate material in contact with the face material as a staggered contact, and the end of the plate material in the rectangular frame direction is contacted with the inner peripheral surface of the rectangular frame. Provided is a building panel characterized in that it is fixed and a space formed by a rectangular frame and a plate material is filled with a heat insulating material, and the vertical frame material, the horizontal frame material and the plate material are made of thinned wood.

  The invention according to claim 2 is characterized in that the radiation shielding sheet is adhered to the surface of the one face member formed by protruding the edge from the outer peripheral surface of the rectangular frame. provide.

  The invention according to claim 3 fixes the protruding edge of one face material of the building panel according to claim 1 or claim 2 to the outer surface of the structural material or non-structural material of the frame structure, There is provided a construction method of a frame structure characterized in that an outer peripheral surface of a rectangular frame of the building panel is fixed to an inner peripheral surface of a frame formed of the structural material or non-structural material.

  Since the building panel according to claim 1 or 2 according to the present invention forms a diagonal lattice by crossing a plurality of plate materials inside each other inside a rectangular frame formed of a vertical frame material and a horizontal frame material. , It has sufficient resistance against the shear deformation of the panel, and as a result, it is possible to sufficiently improve the seismic performance of the wooden or steel frame structure. In particular, the width of the vertical frame material, the horizontal frame material, and the plate material should be about 30 to 150 mm as will be described later, so that there is an effect of reducing the weight of the entire construction panel. Since the lattice is formed, the entire panel has an effect that the resistance to shear deformation is remarkably increased.

In addition, since the strength variation and strain level of each material are absorbed by the slanted grid and uniform, a single material is not required to have uniform strength or low strain. There is an effect that thinned timber having a diameter of 100 mm to 300 mm, which has little practical use at present, is inexpensive and can be used for wood, horizontal frame material and plate material. For this reason, as a result, there is an effect that a high-strength building panel can be provided at a much lower price than a conventional building panel. The term “thinned wood” as used herein refers to timber generated during thinning to thin out standing trees that become dense during the growth of the forest.

Moreover, it is not formed by the board | plate material with which the whole panel was laminated | stacked like patent document 2, but since it has moderate space by an oblique lattice, there exists an effect that it is lightweight. Furthermore, since the present invention makes effective use of thinned wood, it has the effect of promoting forest maintenance.

  In addition, the construction panel according to claim 1 or claim 2 can be continuously produced at a factory, and compared with a case where a stud, a brace, and a torso are provided between pillars at a construction site. There is an effect that a frame building can be constructed in a short construction period.

In addition, since the space formed by the rectangular frame and the plate material in the lattice of the building panel is filled with a heat insulating material, there is an effect of good heat insulation, and further, including the roof portion of the building. In addition, since the entire wall surface, ceiling surface, floor surface, and roof surface can be covered with the building panel according to the present invention, there is an effect that the entire building can be a highly insulated house. When the heat insulating material is a material having resistance to deformation such as foamed urethane foam, the heat insulating material is filled in the space formed by the rectangular frame and the plate material in the lattice, thereby resisting the deformation of the heat insulating material. There is also an effect of increasing resistance to the shear deformation of the building panel by force.

  Further, the building panel according to claim 1 or 2 is such that the edge of the face material on one surface of the rectangular frame protrudes from the outer peripheral surface of the rectangular frame. In addition, the outer surface of the beam can be covered entirely from the left and right or both the upper and lower sides, and if the design is applied to the surface of the face material, it can be used as it is as the siding of the outer wall.

  In addition to the above effects, the building panel according to claim 2 has a radiation shielding sheet adhered to the surface of one face member formed by protruding an edge from the outer peripheral surface of the rectangular frame. Pillars, foundations, and rafters can be covered from both sides with protruding edges of the face material to which the sheet is attached, and the building panel, including the roof portion of the building, wall surface, ceiling surface, floor surface, By covering the entire roof surface with the building panel, there is an effect that it is possible to effectively prevent contamination inside the building of radioactive materials leaked due to a nuclear accident or the like.

  According to a third aspect of the present invention, there is provided a method for constructing a frame structure, wherein the protruding edge of one face material of the building panel according to claim 1 or 2 is made of a structure material or a non-structure material of the frame structure. It is fixed to the outer surface of a pillar, beam, foundation, large draw, joist, rafter, or girder, and the outer peripheral surface of the rectangular frame of the building panel is attached to the column, beam, foundation, In addition to the effects obtained by the construction panel according to claim 1 and claim 2 by adhering to the inner peripheral surface of the frame formed by large drawing, joists, rafters, girders, etc., this application claim produced at the factory By using the building panel according to item 1 or claim 2, there is an effect that a house having excellent earthquake resistance can be constructed in a short construction period and at a low price.

1 is an overall perspective view of a building panel according to the present invention. It is a building panel which concerns on this invention, and is a perspective view which shows the state which took the face material of the one side. It is a partial section state perspective view of the building panel of the present invention. 1 is an overall perspective view showing a state in which a radiation shielding sheet is attached to the surface of one face member formed by protruding an edge from an outer peripheral surface of a rectangular frame, which is a building panel according to the present invention. It is a top view showing the state where the building panel concerning the present invention was inserted and fixed between pillars. It is a front view which shows the state which inserted and fixed the building panel which concerns on this invention between pillars.

  Next, the form for implementing the building panel which concerns on this invention is demonstrated.

  FIG. 1 is an overall perspective view of a building panel 10 according to the first aspect of the present invention, wherein 1a and 1b are vertical frame members, 2a and 2b are horizontal frame members, and ends of the vertical frame members 1a and 1b. The rectangular frame 3 is formed by adhering the end portions to the end portions of the horizontal frame members 2a and 2b. Both sides of the rectangular frame 3 are covered with the face materials 4 and 5, and the edge 4 a of the face material 4 on one surface is formed so as to protrude from the outer peripheral surface 3 a of the rectangular frame 3. In FIG. 1, the edge 5 a of the face material 5 on the other surface is formed flush with the outer peripheral surface 3 a of the rectangular frame 3, but if it covers one surface of the rectangular frame, it is retracted from the outer peripheral surface 3 a. It may be formed.

  As shown in FIG. 4 or FIG. 5, the edge 4a is an outer surface of a structural or non-structural material such as a pillar, beam, foundation, large draw, joist, rafter, or girder of a framed building (FIGS. 5 and 5). 6, the length that can be fixed to the outer surface 30 a, 40 a, 50 a) of the pillar 30, the base 40, and the beam 50 suffices to protrude from the outer peripheral surface 3 a of the rectangular frame 3. The width of the outer surface (outer surfaces 30a, 40a, 50a) of the frame (frame 60 in FIGS. 5 and 6) formed of the structural material or non-structural material of the frame building is sufficient.

The column size of a normal framed building is 105 to 120 mm in width and 210 mm at maximum in areas with a lot of snow. For example, when sticking to the outer surface of a column with a width of 120 mm, the protruding length of the edge 4a is In the case of a column with a width of 210 mm in a region with a maximum of 120 mm and a large amount of snow, the protrusion length of the edge 4a may be 210 mm at the maximum.

As shown in FIG. 6, for example, when the building panels 10, 10 of the present invention are inserted into the left and right frames 60, 60 of the central pillar 30, all of the outer side surfaces 30 a of the pillar 30 are left and right. If the edges 4a, 4a of the building panel 10 on both sides are covered, the outer surface of such a structural material or non-structural material can be covered with the edge 4a of the building panel 10 of the present invention. The aesthetics of the group building will be good.

  As shown in FIG. 2, an oblique lattice 8 is formed inside the rectangular frame 3 by intersecting a plurality of plate members 6, 7, and the intersecting portions of the plate members 6, 7 are in contact with each other. In FIG. 2, the face material 4 side of the plate material 6 is cut out at the intersection of the plate materials 6 and 7, and the plate material 7 is cut out on the face material 5 side not shown. The vertical frame members 1a and 1b, the horizontal frame members 2a and 2b, and the plate members 6 and 7 are all made of thinned wood.

  The length of one side of the diagonal lattice 8 formed of the plate materials 6 and 7 is preferably 200 mm to 300 mm, and more preferably 250 to 300 mm. If it is less than 200 mm, the ratio of the notches of the plate materials 6 and 7 forming the diagonal lattice 8 increases, and the resistance to shear deformation of the panel decreases, and if it exceeds 300 mm, the plate material used for one building panel 10. Since the number of sheets 6 and 7 is reduced, the resistance to shear deformation of the panel is reduced. If it is less than 250 mm, the ratio of the notched portions of the plate members 6 and 7 forming the oblique lattice 8 increases, and the resistance to shear deformation of the panel tends to decrease. The thinning material used for the vertical frame materials 1a and 1b, the horizontal frame materials 2a and 2b, and the plate materials 6 and 7 is suitable for thinning Japanese trees that are durable to changes in humidity and temperature in Japan. Especially, thinned cedar, cypress and pine are more suitable.

  Further, one of the diagonal lattices 8 formed of the plate materials 6 and 7 may be rectangular, and the lengths of adjacent sides may be different. The joint angle between the plate member 6 or 7 and the vertical frame member 1a or 1b is preferably 30 to 60 degrees. In this case, the resistance to shear deformation of the entire building panel is increased, and the seismic resistance of the frame building is increased. It can be improved efficiently. 2 and 3, the joint angle between the plate members 6 and 7 and the vertical frame member 1a or 1b is formed to be approximately 45 degrees, and the resistance force against the shear deformation of the panel is maximized at this angle.

  Further, since the plate members 6 and 7 form the diagonal lattice 8 as the staggered contact as described above, the end portion 6a of the plate member 6 in the direction of the face member 5 is in contact with the face member 5, and the face member 4 of the plate member 7 is contacted. An end portion (not shown) of the direction is in contact with the face material 4 and is fixed to the face material 5 or the face material 4 in the present invention. By using the phase contact, the distortion of each of the plate members 6 and 7 is canceled or restrained, and the entire building panel 10 is hardly warped.

Further, the end 6 b of the plate 6 in the direction of the rectangular frame 3 and the end 7 b of the plate 7 in the direction of the rectangular frame 3 are in contact with and fixed to the inner peripheral surface 3 b of the rectangular frame 3. In the building panel 10 of the present invention, the end portions of the plate materials 6 and 7 in the direction of the face material 4 or 5 are fixed to the face materials 4 or 5, and the end portions of the plate materials 6 and 7 in the direction of the rectangular frame 3 are The rigidity of the panel is enhanced by being fixed to the inner peripheral surface 3b of the rectangular frame 3, and the resistance to shear deformation of the panel is high.

The thickness of the vertical frame members 1a and 1b, the horizontal frame members 2a and 2b, and the plate members 6 and 7 in the direction of the rectangular frame 3 is preferably 10 mm to 50 mm, and more preferably 20 to 40 mm. If it is less than 10 mm, sufficient resistance to shear deformation of the panel cannot be obtained, and if it exceeds 50 mm, the weight of the entire building panel 10 increases and handling becomes inconvenient. If it is less than 20 mm, there is a tendency that sufficient resistance to shear deformation of the panel cannot be obtained, and if it exceeds 40 mm, the weight of the building panel 10 as a whole increases and the handling tends to be inconvenient.

The widths of the vertical frame members 1a and 1b, the horizontal frame members 2a and 2b, the plate members 6 and 7 in the direction of the face members 4 and 5 are the columns, beams, foundations, It has only to have a dimension that can be fixed to a frame formed of a pull, joist, rafter, or girder, and is preferably at least 30 mm and at most 150 mm, more preferably 45 to 100 mm. If it is less than 30 mm, the seismic performance of the frame building is insufficiently improved, and if it exceeds 150 mm, the weight of the building panel 10 as a whole increases and the handling becomes inconvenient. If it is less than 45 mm, the seismic performance of the frame building tends to be insufficient, and if it exceeds 100 mm, the overall weight of the building panel 10 tends to increase and the handling tends to be inconvenient.

As shown in FIGS. 5 and 6, the width of the vertical frame members 1a and 1b, the horizontal frame members 2a and 2b, the plate members 6 and 7 in the direction of the face material 4 and 5 in the direction of the column dimensions is as follows. When inserted between the columns 30, 30, it is preferable that the width is 30 mm to 40 mm smaller than the width of the columns 30. For example, when the column 30 is 105 mm square, the width of the vertical frame members 1a and 1b, the horizontal frame members 2a and 2b, and the plate members 6 and 7 in the direction of the face members 4 and 5 is preferably about 60 mm. , 5 is preferably 9 mm. Accordingly, a space of 30 mm to 40 mm is formed inside the pillar 30, and electrical wiring and piping can be provided in the space.

In addition, as for the face materials 4 and 5, the thickness of 6-40 mm of the common plywood generally used is preferable, More preferably, it is 9-20 mm in thickness. Use is preferable from the viewpoint of effective use of thinned wood. If the thickness is less than 6 mm, the deformation (warp) in the thickness direction of the building panel 10 becomes large, and if it exceeds 40 mm, the weight of the building panel 10 as a whole increases and the handling becomes inconvenient. If it is less than 9 mm, deformation (warp) in the thickness direction of the building panel 10 tends to increase, and if it exceeds 20 mm, the overall weight of the building panel 10 tends to increase and handling tends to be inconvenient.

It should be noted that 12 mm normal plywood is used for the face materials 4 and 5, the vertical frame materials 1 a and 1 b, the horizontal frame materials 2 a and 2 b, and the plate materials 6 and 7 having a thickness of 30 mm and a width of 60 mm are used. Is 45 degrees, the length of one side of the diagonal lattice 8 is 250 mm, and the size of the rectangular frame 3 is 900 mm wide and 2000 mm long, the weight is about 20 kg or less, and it can be transported sufficiently by one person.

As shown in FIGS. 2 and 3, a space formed by the rectangular frame 3 and the plate members 6 and 7 is filled with a heat insulating material 9 made of urethane foam. The heat insulating material 9 may be glass wool other than urethane foam.

For joining the vertical frame members 1a and 1b and the horizontal frame members 2a and 2b and fixing the plate members 6 and 7, the rectangular frame 3, and the face members 4 and 5 to each other, it is common to use nails, staples, adhesives, etc. Although an adhering method can be used, it is preferable to use an adhesive and a wood screw together because stable bonding can be obtained.

FIG. 4 is an overall perspective view of the building panel 20 according to the second aspect of the present invention. A radiation shielding sheet 12 made of lead or high-density tungsten is attached to the surface of the face material 4.
