DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a load-bearing wall structure of a wooden building such as a house.

[0002]

2. Description of the Related Art Conventionally, a wall structure of a wooden building is constructed by arranging a plurality of narrow reinforcing bones referred to as rafters in a row between a pair of left and right structural columns, and applying a plywood to the reinforcing bones and performing a cross finish. The wall structure which forms a wall surface is adopted.

[0003]

However, since the cross-sectional area of the reinforcing bone is small in the above-mentioned wall structure, the strength of the structure against vertical load cannot be sufficiently obtained, and the wall structure has a problem of lack of earthquake resistance and durability. In addition, since the space between the structural column and the reinforcing bone is merely filled with glass wool or the like, the airtightness and the sound insulation are impaired.

Further, these wall structures must be constructed on site, and the work is complicated, and the construction period and construction cost are increased.

[0005]

According to the present invention, as a means for solving the above-mentioned problems, burying grooves are formed in four corners of a wooden prism in the longitudinal direction, and longitudinally extending on two right and left sides of the wooden prism. A prism material having a joining groove formed in the direction is used as a bearing wall forming material.

The plurality of wooden prisms are in contact with each other on the two left and right sides where the joint groove is formed, and the embedment receiving grooves of the adjacent wooden prisms are formed on the longitudinal side of the contact surface by the contact. The two front and rear sides of the wooden prism are aligned with each other, and the joining grooves of the adjacent wooden prisms are aligned with the abutting surface.

[0007] A burying tree is inserted into the matching grooving receiving groove, and a nut for connecting each wooden prism material is press-fitted into the matching grooving groove to form a bearing wall block. This load-bearing wall block is erected in a wall-forming space defined by a pair of left and right structural columns arranged at intervals and a pair of upper and lower horizontal members laid on the structural columns, and on the side surfaces of the structural columns. The outer surfaces of the left and right wooden prism members forming the load-bearing wall block are abutted, and the respective end surfaces of each wooden prism material forming the load-bearing wall block are affixed to the inner surface of the horizontal member. The structure was configured such that a bearing wall was formed by fastening to the above-mentioned structural column and the horizontal member with a fastening hardware.

[0008]

According to the present invention, a load-bearing wall block formed by closely arranging and connecting wooden prisms in a wall-forming space formed by structural columns and horizontal members is built up and integrated into a wall. The structure has a wide sectional area, and the seismic resistance and durability of a wooden building such as a house can be dramatically improved with a simple configuration.
In addition, excellent airtightness, sound insulation effect, and heat insulation effect can be obtained.

The airtightness and the sound insulation effect can be further improved by the employment and burial that are press-fitted between the wooden prisms, and the strength as a bearing wall can be improved.

Furthermore, it is possible to fully enjoy the advantages of wood such as the self-regulating function of humidity and to reproduce the warm appearance of wood in a building, thereby improving the quality of the building in terms of both ease of living and appearance. .

In addition, this load-bearing wall structure can form a load-bearing wall by a simple construction in which a load-bearing wall block manufactured in advance is inserted and fastened to a frame of a building (between a structural column and a horizontal member), thereby shortening the construction period and reducing construction cost. Contributes to savings.
