The steel house (SH) construction method described above is
Is a method for constructing a wall frame panel of a building by joining a frame material of thin-sheet lightweight shaped steel with a drill screw, and constructing a frame with a bearing wall panel in which a structural face material 6 is attached to this wall frame. ,
As its merit, the thin sheet light-weight steel does not require welding work, is easy to cut and drill, has light members, and can be carried manually, resulting in high work efficiency and low manufacturing cost. As for the wall, the load-bearing wall panel is easy to secure stable product precision, the panel is prefabricated, and therefore the construction period is shortened and the panel precision is secured, so construction is easy.
If the scale is about tsubos, it will take 2.0 days to build. Therefore, it is an economical structure in the structural field of low-rise buildings on the second and third floors.

[0010]

On the other hand, a steel house mainly composed of thin and lightweight section steel has the following drawbacks.

The opening formed on the wall surface such as a doorway or a window has insufficient strength to support a vertical load from the upper floor. Therefore, the above-mentioned lintel is provided above the opening, and the lintel is inserted through this lintel. The vertical load that is applied to the opening from above is sent to the vertical frame of the load-bearing wall panels on both sides. However, it is necessary for the lintel to have sufficient strength to withstand the vertical load from the upper floors, such as the roof and floor, so it is necessary to use a combination of multiple thin sheet lightweight shaped steels. The structure of the lintel is complicated, and both ends of the lintel are attached to the side edges of the load-bearing wall panels located on both sides of the opening. However, there was a problem that the height of the opening (shown by h in FIG. 11) was restricted by the presence of the lintel.
