DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel, a plurality of floor panels each for a floor, a wall, and a roof.
The invention relates to a steel basement comprising wall panels and roof panels and constructed with a relatively large living room or opening.

[0002]

2. Description of the Related Art Recently, basements are often provided in ordinary houses, and this kind of basement has a shortened construction period,
It is constructed by connecting a plurality of floor panels, wall panels, and roof panels, each of which is configured for a floor, a wall, and a roof, with a plurality of joining bolts or the like in order to save labor and the like.

[0003] When a ground building is constructed on such a steel basement, the steel basement also serves as the foundation of the ground building, and not only its own weight but also the pillars of the ground building at the time of an earthquake or a storm. And external force acting on the wall, for example, FIG.
As shown in (a), it is better for the steel basement wall 16 to be vertically connected to the pillars and walls 17 of the ground building.
There is no particular problem since the external force acting on 17 is directly transmitted to the wall 16 of the steel basement.

[0004]

However, due to the layout of the basement, for example, as shown in FIG. In some cases, it may not be desirable to provide the wall 16 underneath, and in such a case, excessive force (force for pushing and pulling the steel basement by rotating the wall of the ground building) is applied to the roof of the steel basement. The roof of the basement is deformed as shown in FIG. 8 (c), which may cause the ground building to be distorted, which is extremely dangerous.

[0005] In particular, a steel basement is different from a conventional basement with a reinforced concrete structure which is integrally constructed, and is susceptible to a large external force such as seismic force because it is weak in rigidity and mechanical continuity due to its assembly type. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a steel basement that enables effective reinforcement when a large living room is provided in the steel basement.

[0007]

SUMMARY OF THE INVENTION A steel basement according to claim 1 includes a plurality of floor panels, wall panels, and roof panels respectively configured for floors, walls, and roofs, and includes a ground building.
