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 structure of a building that forms a wooden house by a frame construction method.

[0002]

2. Description of the Related Art Conventionally, in a wooden house by a frame construction method, a foundation is provided on a cloth foundation, a pillar which is a shaft member is erected on the foundation, and a horizontal member such as a girder or a beam is arranged on the pillar. However, diagonal braces are provided between the columns to strengthen horizontal bearing capacity.

Further, as a wooden house in which the wall surface has a high horizontal proof performance, a wooden panel construction method in which a panel material such as plywood is fitted or attached between the shaft members of the wooden framework is also used.

Further, as disclosed in Japanese Patent Application Laid-Open No. 11-22004, there is also proposed a construction method in which a steel frame is fitted into the opening of a wooden frame and connected to a base or a beam. In this case, the frame is made of a steel frame with braces fixed to increase horizontal bearing capacity and improve seismic performance.

[0005]

In the conventional shaft construction method in which the wooden shaft members are assembled in the above-mentioned conventional technique, the horizontal proof stress of the wall surface is limited to the strength of the wood even if braces are provided, and the wooden house construction There was a limit to the layout of large spaces and the flexible design of spaces by changing partitions.

Also, in the panel construction method using plywood, the shaft member has a limit in the strength of the plywood, and the seismic performance capable of forming a sufficiently large space cannot be obtained.

Further, in the case where the steel frame is fitted to the shaft member, only the steel material is fitted to the opening portion of the shaft member, so that only the horizontal proof performance which is not much different from the panel construction method can be obtained. It was a thing.

The present invention has been made in view of the problems of the above-mentioned conventional techniques, and can significantly improve the horizontal rigidity of a house having a wooden frame structure, and has a good workability in a building. It is intended to provide a wall structure.

[0009]

According to the present invention, there is provided a vertical structure formed by a column which is a vertical shaft member of a building and a horizontal shaft member such as a base, a girder, or a cross member. A rectangular frame member that is in contact with the shaft member is fitted in the space of the direction, and diagonal members such as braces are provided in the frame member. A lower fixing member that is made of a steel material such as a letter and that fixes the frame member to the cloth foundation in the vertical direction, and an upper fixing member that fixes the frame member to a horizontal member such as a girder or a beam, and further in the vertical direction. Is a load-bearing wall structure of a building in which a stabilizing member fixed to each of the cloth foundation and the horizontal member is provided on the opposite side of the frame member with the shaft member sandwiched therebetween. The stabilizing member mainly contributes to stabilizing the building structure against horizontal force. Both ends of the diagonal member are welded and fixed to the frame member.

Further, the frame member and the stabilizing member are connected to each other with bolts and nuts or the like, with a pillar interposed therebetween. Further, the frame member on the upper floor is connected and fixed to the frame member provided on the base by sandwiching the horizontal member with the upper fixing member.

The load-bearing wall structure of a building according to the present invention is intended to greatly improve the horizontal bearing capacity of a wooden house by the wooden frame construction method by fitting between the shaft members of the wooden frame structure.

The upper fixing member 36 is fixed to the floor beam 16 with the nut 40 or the like with the floor beam 16 interposed therebetween. As will be described later, when there is the frame member 22 on the upper floor, the connecting bolt 38 is provided on the upper floor. It is also used as a fixing member for the frame member 22.

Further, the cloth foundation 11 and the base 1 are provided on the opposite side of the frame member 22 with the pillar 14 which is a vertical shaft member interposed therebetween.
A stabilizing member 44, which is fixed to 3, is provided. The stabilizing member 44 is intended to stabilize against a horizontal force, and is made of an angle member having an L-shaped cross section or a steel member having a square shape,
A lower fixing member 46 having the same structure as the lower fixing member 26 is formed at the lower end portion, and the anchor bolt 28 is used to form the cloth foundation 1
It is fixed at 1. An upper fixing member 48 having the same structure as the upper fixing member 36 is provided on the upper end portion of the stabilizing member 44, and is connected and fixed to the floor beam 16 by the upper fixing member 48. In addition, the frame member 22 and the stabilizing member 44 are the pillar 1
4 are connected to each other by bolts 50 and nuts 52 and fixed to the pillar 14.

The frame member 22 provided on the base 13 is sandwiched by the floor beams 16 which are horizontal members, and the frame member 22 on the upper floor is connected and fixed by the other end of the upper fixing member 36. ing. The other end of the connecting bolt 38 of the upper fixing member 36 is attached to the holding portion 55 of the fixing member 54 of the frame member 22 on the upper floor.
It is connected and fixed by a nut 40. Frame member 2 on the upper floor
The upper end of 2 is connected and fixed to the shed beam 20 by a fixing member 54 having the same structure. In addition, the stabilizing member 4 on the upper floor
Similarly, 4 is a fixing member 5 at the other end of the upper fixing member 48.
6 is connected and fixed to the beam 16 and the upper end is also fixed by the fixing member 5.
