Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a load-bearing wall panel that forms a load-bearing wall by fixing a plywood having a large plate thickness, which is called structural plywood, to a column and a horizontal member such as a base, a girder, or a beam.

[0002]

[Prior art]

 As a conventional construction method using this type of load-bearing wall panel, load-bearing wall panel building was constructed in which the load-bearing wall panels were formed by fixing the four edges of the above-mentioned structural plywood to columns and horizontal members with long nails. The construction method is known.

[0003]

[Problems to be solved by the device]

 In such a load-bearing wall panel construction method, not only the plywood with a large thickness protrudes inward from the wall, but it is also necessary to form a decorative wall on this plywood for the sake of aesthetics of the room. There is a drawback that the indoor area of a building with a constant space is reduced.

Further, even if a plaster board having a strong refraction resistance is stretched on a structural plywood as a base of a decorative wall, this plaster board does not increase the strength as a strength wall, and the strength as a strength wall panel construction method. In order to raise the level, structural plywood or plasterboard had to be struck on the side of the pillar where structural plywood was not attached.

Further, in this load-bearing wall panel construction method, structural plywood is attached to one surface or both surfaces between the pillars. Therefore, in the case of only one surface, the work of installing the indoor piping and wiring does not depend on the space between the pillars. It was limited to one side, and there was a problem that work could not be performed in the case of both sides.

The present invention solves the above-mentioned problems in the conventional load-bearing wall panel construction method, does not reduce the indoor area, and increases the strength of the load-bearing wall panel by using plasterboard as the wall foundation. The purpose is to provide a bearing wall panel that enables piping and wiring work from any surface between columns.

[0007]

[Means for solving the problem]

 The load-bearing wall panel of the present invention is intended to achieve the above-mentioned object, and the means for achieving it is as follows. The front and back sides of thick plywood whose horizontal width is between columns and vertical width is between horizontal members such as base, girder and beam. It is characterized by driving four sapwood to be struck on pillars and horizontal materials such as foundations, girders, and beams on the four edges on both sides.

[0008]

[Action]

 In the load-bearing wall panel of the present invention, the load-bearing wall panel is constructed by fixing four sapwood to the four sides of the front and back sides of the thick plywood with the width between the columns and the width between the horizontal members. A load-bearing wall panel can be inserted between columns and between horizontal members, and fixed by striking four columns on the columns and horizontal members to prevent the columns from tilting with respect to the horizontal members. The earthquake resistance of can be improved.

Since the thickness obtained by adding the thick plywood and the four side materials fastened to both surfaces thereof is the same as the thickness of the pillar, the four side materials do not project to the inside or the outside of the pillar, so that the pillar Since the surface is the backside of the interior wall foundation, thick plywood does not protrude to the interior side, and the interior area is wider than the conventional load-bearing wall panel building structure. The nature is further enhanced.

Furthermore, since the thick plywood is located at the center of the pillar, a space for piping and wiring is formed on any surface of the thick plywood, and therefore piping and wiring work can be performed from any surface between the pillars. Therefore, the difficulty of the work due to the limitation of the work surface is eliminated.

Further, by fixing the corner metal fittings to the four corners of the load-bearing wall panel with fastening materials such as nails and screws that reach the pillars and lateral members, it is possible to more reliably maintain the four corners of the load-bearing wall panel at right angles. The earthquake resistance is further enhanced.

【Example】

 An example of the present invention shown in FIGS. 1 to 3 will be described below. FIG. 1 is a perspective view of a construction method in which a load bearing wall panel A is attached. For example, the lateral width of a structural plywood 1 having a thickness of 9 mm, which forms the load bearing wall panel A, is a dimension between columns 2, for example, Japan. If the pitch of the pillars 2 often used in construction is 91.0 cm and the cross-sectional dimension of the pillars 1 is 10.5 cm, it is 80.5 cm.

The vertical dimension of the structural plywood 1 is the same as the dimension from the base wood 3 to the horizontal members 4 such as girders and beams, that is, 270 cm. Is fixed by nailing four side materials 5 and an intermediate material 6 each having a thickness of 48 mm and a width of 45 mm with a nail.

Therefore, the lateral dimension of the load-bearing wall panel A corresponds to the dimension between the columns 2 of 80.5 cm, and the vertical dimension corresponds to the dimension of the base material 3 and the horizontal member 4 of 270 cm. Also, it can be inserted without creating a gap between the wooden piece 3 serving as the base and the horizontal member 4.

The surface of the four side bars 5 of this load-bearing wall panel A and one surface of the pillar 2 are made to coincide with each other, and the load-bearing wall panel A inserted between the pillars 2 and the base wood 3 and the horizontal member 4 is inserted. The sapwood 5 is struck by N50 nails at intervals of 15 cm or less to the pillar 2, the wooden piece 3 of the base, and the horizontal member 4 to fix them.

Then, the thickness of the load-bearing wall panel A, which is the sum of the thicknesses of the four-sided wood 5 on both sides and the structural plywood 1, is equal to the cross-sectional width of the pillar 2 of 10.5 cm. Both the front and back surfaces of 6 are flush with the surface of the pillar 2, and a wall base material such as plasterboard or an outer wall material can be placed on this surface.

As described above, the structural plywood 1 of the load bearing wall panel A in which the load bearing wall panel A is fixed between the pillar 2, the base wood 3 and the horizontal member 4 has the thickness and the reinforcement of the four side members 5. Will prevent the right angle between the pillar 2 and the base wood 3 and between the pillar 2 and the cross member 4 from changing, and it is possible to prevent the pillar 2 from tilting due to an earthquake or the like and the building collapse. .

Then, a wall base such as a wall base plywood or plaster board is attached to the indoor side surfaces of the pillars 2 and the four side members 3 and the intermediate members 5 of the load bearing wall panel A, and an indoor wall can be formed by applying wallpaper or the like. Also, the outer wall can be formed by hammering the outer wall material.

Next, another embodiment shown in FIGS. 4 to 6 will be described below. In this embodiment, the load-bearing wall panel A of the previous embodiment is fixed by nailing it between the pillars 2 on the left and right and between the timber 3 of the base and the cross member 5 on the upper and lower sides in the same manner as in the previous embodiment. However, the following corner fittings B are brought into contact with the insides of the four corners of the four side members 5 of the load bearing wall panel A.

In this corner fitting B, a bent piece 7 having a plurality of insertion holes 8 is formed at the same height as the four side members 5 with respect to two orthogonal sides of a right triangle. The bent piece 7 of the corner fitting B is brought into contact with the four side members 5 at the four corners.

Then, a nail 9 or a screw is driven into the pillar 2, the base wood 3, and the horizontal member 4 from the insertion hole 8 of the bent piece 7 through the four side members 5 to attach the load bearing wall panel A and the corner metal fitting B. It is fixed to the pillar 2, the base material 3 and the horizontal member 4, and this corner metal fitting B ensures that the pillar 2 and the base wood 3 and the pillar 2 and the horizontal member 4 are maintained at right angles together with the structural plywood 1. It is possible to obtain the earthquake resistance of 2.5 times stronger than the conventional one.

As described above, in each of these examples, since the structural plywood is located at the center position of the pillar, any of the surfaces can be used as the piping and wiring side, and the bearing wall of the outer wall surface can be used. In the case of panel A, it is possible to put a heat insulating material on the outer structural plywood surface, while if a plaster board with a thickness of 12 mm is used as the wall foundation, double on one side and double on both sides, a total of 4. 5 times greater earthquake resistance can be obtained.

The present invention can be applied widely to the two-by-four construction method and the metal fitting construction method other than the conventional wooden constructions exemplified above, and can be widely used.

[0024]

[Effect of device]

 As mentioned above, the present invention surely prevents the tilting of the pillars, can obtain a load-bearing wall that is stronger than the conventional load-bearing wall panel and its construction method, and uses a thicker plaster board as the wall foundation. As a result, the earthquake resistance of the building is further enhanced, and since the structural plywood does not project to the indoor side, the indoor area does not decrease and the indoor space can be expanded.

Since the structural plywood is located at the center position of the pillar, a space that serves as a piping and wiring space is formed on any side of the structural plywood, and the construction is performed from any surface of the structural plywood. Not only can it be used for wiring work, but it can be used not only as a wall that separates interior spaces, but also as a boundary wall between the interior and exterior by putting an insulating material on one side and applying an exterior plate. .

Further, since this load bearing wall panel can be produced in a factory without requiring a special construction method or work, it can be supplied at a low cost and in large quantities without the need for capital investment. Since it does not require skill or special tools, it has the effect that it can be easily installed.
