Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load-bearing wall panel, and more particularly, to a load-bearing wall panel which is easy to construct a building and has sufficient strength.

[0002]

2. Description of the Related Art There are various construction methods for building buildings such as wooden houses. And shorten the construction period,
In order to reduce the cost required for construction, a so-called prefabricated house construction method is known. According to these methods, pillars, girders,
Since other building materials are prepared (precast) and assembled at the building site, the construction period can be shortened.

[0003] That is, in these construction methods, pillars,
Girder (beam), bracing, wall panels, etc. are standardized, so assemble this standardized framework of pillars, girders, studs, bases, etc., and beat or fit the wall panels on this Since the construction is performed, a building such as a predetermined house is easily formed and the construction period is shortened.

[0004]

However, in the case of the above-mentioned conventional method, the following problems remain regarding the construction. In other words, the number of parts such as columns, girders (beams), studs, braces, and the like as building materials for assembling the framework of the building increases. Therefore, it is necessary to find necessary parts at a construction site, and it is necessary to assemble each one of them. In addition, it is difficult to position the wall panel at the time of striking or fitting. Furthermore, it takes time and effort to determine the parallelism, direction, and squareness with the base. Therefore, although it depends on the structure and form of the building, there is a limit to shortening the construction period, and it is difficult to reduce the building cost. And other issues.

[0005] In view of the above, the present inventor has dealt with such a problem. And, between the upper frame material and the lower frame material of the rectangular frame, there are a plurality of studs having a strength connecting the upper frame material and the lower frame material, and the upper frame material of the rectangular frame body A wall panel for a building having a "mortise" engaging with the spar on the upper surface of the spar and a "mortise" engaging with the base on the lower surface of the lower frame material of the rectangular frame. Since this building wall panel is a panel body incorporating pillars such as studs, it is possible to reduce the number of parts at the time of building construction, so that the number of steps required for building construction can be reduced, and the upper frame material of the rectangular frame body The upper surface of the lower frame has a tenon that engages with the spar, and the lower surface of the lower frame member has a tenon that engages with the base. Since it can be performed accurately, there is an advantage that good parallel and right-angle accuracy can be easily obtained.

However, in the case of this building wall panel, a "tenon" for engaging a girder and a base is provided in a rectangular frame,
Since the "tenon" protrudes from the outer periphery of the panel body, there is also a problem in that handling requires caution in terms of transportation and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and an object thereof is to provide a load-bearing wall panel capable of improving handleability and construction workability and improving strength thereof. Is to provide the body.

[0008]

According to another aspect of the present invention, there is provided a load-bearing wall panel according to a first aspect of the present invention, comprising a frame formed by left and right columns and upper and lower horizontal members. A load-bearing wall panel body attached to the rectangular frame body, and a streak that connects between upper and lower corners of the internal space of the rectangular frame body, and one side of the rectangular frame body A heat insulating material held between the structural rigid plate stretched, the rectangular frame, the braces, and the structural rigid plate, and formed between the other surface of the rectangular frame and the heat insulating material. The rectangular frame has a hold-down metal binding hole at a position near the corner of the rectangular frame, and the side of the brace where the structural rigid plate is not provided. Attach hardware to attach the hold-down hardware at the location facing the hold-down hardware binding hole provided on the body Characterized in that it forms a. Further, the load-bearing wall panel body of claim 2 is the above-mentioned claim 1.
In the invention, the hold-down hardware is attached to the hardware attachment portion of the bracing. The load-bearing wall panel body according to claim 3 is the above-described claim 1.
In the invention of the second aspect, the positions near the corners of the rectangular frame are the left and right corners of an upper frame member and the left and right corners of a lower frame member constituting the rectangular frame.

Here, the left and right columns refer to columns such as through columns and pipe columns, and the horizontal members refer to horizontal members such as bases, girders or beams. The structural rigid plate is also called a structural plywood, and the side on which the rigid plate is stretched is usually the indoor side in a building. Then, an interior finishing sheet such as a cloth can be stuck on this surface. However, this may be the outdoor side depending on the construction form of the building. As the heat insulating material, for example, urethane foam, glass wool, or the like can be used. Further, the hold-down metal means a metal used for directly or indirectly connecting columns and structures arranged vertically with a bolt and a bolt holding metal via a horizontal member.

The load-bearing wall panel body of the present invention can be mounted, for example, in a frame formed by through columns and tube columns constituting left and right columns, and a base and girder constituting upper and lower horizontal members. That is, the panel body is fitted into the frame, and the hardware main body of the hold-down metal fitting is attached to the hold-down metal fitting mounting part of the brace, or the metal is attached to the hold-down metal fitting mounting part of the brace in advance. The panel body to which the hardware main body of the hold-down hardware is attached is fitted into the frame, and a bolt is inserted into a hold-down hardware fastening hole formed in the rectangular frame body to directly or directly hold the hardware. By indirectly tying, it can be mounted and fixed in the frame. In the case of indirect binding, for example, a pull-in hardware is used in addition to the hold-down hardware. A bracing is pre-installed in the load-bearing wall panel, and is mounted in the frame with a hold-down hardware through the bracing, so that it is inferior to the conventional framing method using a conventional method. Can maintain the strength without cracks.

[0011]

As is apparent from the above description, according to the load-bearing wall panel of the present invention, a brace is provided between the upper and lower corners of the internal space of the rectangular frame, and one side of the rectangular frame is provided. Since the panel is made of a panel having a structural rigid plate and a heat insulating material layer and a void provided in the internal space of the rectangular frame, its strength can be improved. Further, in the case of the panel body in which the hardware main body of the hold-down hardware is mounted on the hold-down hardware mounting portion of the bracing, a panel body having the strength can be obtained in advance. Further, a hole for holding down hardware is provided at a position near a corner of the rectangular frame, and the side of the brace where the structural rigid plate is not provided is provided for holding down hardware provided on the rectangular frame. Since the hardware attachment part for attaching the hold-down hardware is formed at the location facing the hole, the number of parts at the time of building construction can be reduced, so the number of steps required for building construction can be reduced and the alignment can be accurately performed. It can be carried out.
