By reducing the number of anchor bolts,
Foundation work can also be speeded up. Further, since the floor panel is not bolted to the side surface of the base, but is installed on the floor panel receiving member protruding to the side surface of the long base, it can be easily installed even if a large floor panel is used. That is, at the time of construction, the floor panel and the floor panel receiving metal fitting can be joined together by bolts or the like with the floor panel placed on the floor panel receiving metal fitting. Therefore, it is not necessary to perform bolting work while the floor panel is hung by a crane, and even a large and heavy floor panel can be easily and safely constructed. By using such a large floor panel, the number of floor construction steps can be reduced. In addition, since the floor panel is installed on the floor panel support that projects to the side of the long base, it does not hinder the construction of outer walls or columns on the base. Since the floor panel itself is constructed with a floor panel in which a joist is installed between floor beams made of parallel shaped steel and a face material is stretched,

In the floor / outer wall structure , the long base is grooved steel that is open to the outside, and the floor panel has a received product at the corner between the floor beam and joist on the outer periphery. When the received hardware of the panel is received and bolted, it is possible to support the floor panel by the received hardware with a small number of received hardware, reducing the joining work such as bolting and floor assembly. Work time can be shortened. The floor
In the outer wall structure , the long base is made of H-shaped steel, the receiving step portion is provided at the middle height position of the floor panel support, and the joist at the outer peripheral portion of the floor panel is a member having a lower vertical width than the floor beam. It is assumed that the floor girder is assembled so that the lower surface position is higher than the lower surface position of the floor girder, and the joists of the outer peripheral part are placed on the receiving step part of the floor panel bracket. If you do so, by placing the floor joists on the outer periphery of the floor panel on the receiving step of the floor panel bracket, place the floor panel on a long base in a stool-like manner and attach it safely and quickly. You can In the floor / outer wall structure using the long base, when the outdoor surface of the long base is covered with a base cover having a heat insulating material, the base part can be heat-treated at the same time as the base part is insulated.
