の提供にある。In the conventional method of constructing a steel frame structure, concrete is cast on a deck to form a floor, so that the weight is large. In addition, since concrete is cast, it cannot be used as a scaffold until the concrete is hardened, so that there is a problem that the construction period becomes longer.
For example, in the case of a 10-story steel structure having a total area of 1,000 tsubo, the floor slab's own weight is 990 tons, and it takes about 10 months to complete the construction. The problem to be solved by the present invention is to solve the conventional problems and to provide a construction method for a steel structure having a new concept of being lightweight, capable of shortening the construction period, being inexpensive, and having good workability.

火性もある。According to the present invention, after a steel frame is constructed, a lightweight floor slab is erected on a lightweight floor slab receiving frame mounted on a beam steel frame to temporarily establish a floor. This floor is temporarily installed from the lower floor, and it can be used as a scaffolding floor, so that temporary light floor slabs on the upper floor can be temporarily installed, thereby improving workability. A lightweight floor slab is temporarily installed, the end faces of the lightweight floor slab are connected by a connecting member, and the gap is repaired with a fireproof board or the like. After these repairs, a refractory material such as rock wool is sprayed on the exposed surface of the lower part of the steel frame and the lower end surface of the lightweight slab to perform fireproof coating.
In this way, the floor and frame are constructed. In addition, since the lightweight floor slab is filled with hard foam resin, it can be made much lighter than conventional reinforced concrete only floors, and the strength burden on steel frames, foundations and piles is reduced, and it is small and lightweight. And the weight and construction cost of the entire building can be greatly reduced. Moreover, since the surface is a fire-resistant board, there is also fire resistance.
