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 mainly composed of a thin steel plate, which constitutes an internal structure of a building wall.

[0002]

2. Description of the Related Art A conventional load-bearing wall structure has been constructed by attaching a load-bearing surface material made of plywood or the like to one surface of an outer peripheral frame formed by combining channel steel in a rectangular shape.

[0003]

When the same structure as the conventional load-bearing wall structure is formed of a thin steel plate, the outer peripheral frame has a groove shape, that is, a shape in which one side is opened, so that the outer peripheral frame has a large axial compression force. On the other hand, buckling is likely to occur, and it is difficult to secure the required proof stress. In the conventional structure, the entire load-bearing wall structure cannot be made of a thin steel plate. Accordingly, an object of the present invention is to provide a load-bearing wall structure having a structure that can be entirely formed of thin steel plates.

[0004]

In order to solve the above problems, according to the present invention, a load-bearing wall structure is attached to at least one surface of a face plate made of a thin steel plate and is abutted and fixed. The reinforcing member is formed by molding a thin steel plate so as to form a vertically continuous convex portion, and both sides of the convex portion are fixed and attached to a face material.
The face material made of a thin steel plate has a predetermined proof strength in the tensile direction, but when a compressive load is applied, it tends to buckle, and can hardly resist the compressive load. In the present invention, since a reinforcing material having a vertically continuous convex portion is attached to the face material, the reinforcing material can withstand a load in the vertical direction, and is combined with a face material acting as a brace against a tensile load. A load-bearing wall structure having a reasonable structure can be constructed. Further, since the reinforcing member has a cylindrical shape with both side portions of the convex portion fixed to the face material, buckling due to a vertical load hardly occurs, and the reinforcing member can also be formed of a thin steel plate. In addition, face materials,
Since the reinforcing material is also made of thin steel plate, the fixing of both is not limited to penetrating fixtures such as tapping screws, riveting, etc.
It can also be performed by welding or swaging.

The reinforcing member may be formed by molding a thin steel plate so that a plurality of convex portions are formed in parallel, and the reinforcing member may be fixed to the face material between the convex portions. According to this configuration, it is possible to further reinforce the face material.

Further, a horizontal reinforcing member may be provided on at least one of the upper end and the lower end of the face member, and the end surface of the reinforcing member may be brought into contact with the horizontal reinforcing member. According to this configuration, the vertical load applied to the horizontal reinforcing member is reliably transmitted to the reinforcing member, and the vertical load can be distributed to and borne by each reinforcing member. improves.

Further, a horizontal reinforcing member may be formed by bending a face member extending above or below the reinforcing member end into a prismatic shape. According to this configuration, since the horizontal reinforcing member and the face material are integrally formed, the connection between them is strong, and the step of joining the two is not required, so that the number of manufacturing steps can be reduced.

On the other hand, the upper end and / or lower end of the face material may be extended. According to this configuration, the beam to which the load-bearing wall structure is attached using the extension of the face material,
Since it can be directly joined to a foundation or the like, the joining is easy, and since the face materials are directly joined, the joining can be performed firmly and reliably.

[0019]

The present invention is as described above, and the face material made of a thin steel plate has a predetermined strength in the tensile direction.
When a compressive load is applied, buckling is likely to occur, and the compressive load can hardly be counteracted. In the present invention, since a reinforcing material having a vertically continuous convex portion is attached to the face material, the reinforcing material can withstand a load in the vertical direction, and is combined with a face material acting as a brace against a tensile load. A load-bearing wall structure having a reasonable structure can be constructed. Also,
Since the reinforcing material has a cylindrical shape with both sides of the convex portion fixed to the face material, buckling due to a vertical load is unlikely to occur, and the reinforcing material can also be made of a thin steel plate, so that both the face material and the reinforcing material are thin. It can be made of steel plate. Further, since both the face material and the reinforcing material are made of a thin steel plate, the fixing of the both can be performed not only by tapping screws or rivets, but also by welding.

In the case where the reinforcing member is formed by molding a thin steel plate so as to form a plurality of convex portions in parallel, and the reinforcing member is fixed to the surface material between the convex portions, The material can be reinforced more strongly, and a load-bearing wall structure having higher strength can be formed.

Further, when a horizontal reinforcing member is provided on at least one of the upper end and the lower end of the face member, and the end surface of the reinforcing member is brought into contact with the horizontal reinforcing member, the vertical load applied to the horizontal reinforcing member is increased by the reinforcing member. , And the vertical load can be distributed to each reinforcing member to bear the load, thereby improving the strength of the load-bearing wall structure against the vertical load.

Further, when the horizontal reinforcing material is formed by bending the vertically extending face material into a prismatic shape, the horizontal reinforcing material and the face material are integrally formed, so that the connection between the two is strong, and Since the step of joining them is not required, the number of manufacturing steps can be reduced, and a bearing wall structure having high yield strength and high productivity can be configured.

On the other hand, by extending the upper end and / or the lower end of the face material, it is possible to directly connect to the beam, foundation, etc. on which the load-bearing wall structure is attached by using the extended part of the face material. In addition, since the face materials are directly joined, the joining can be performed firmly and reliably.
