<p>PROBLEM TO BE SOLVED: To provide a floor slab which is more lightweight than a conventional floor slab and construction using the lightweight floor slab, to improve work efficiency, and to solve problems of conventional floor slab construction.SOLUTION: A lightweight floor slab has a plurality of pipes arranged in concrete of the floor slab in a connection direction of floor slabs, and the pipes are arranged at intervals in a direction crossing the connection direction of the floor slabs, and united with the concrete in the presence of a design load. A pipe has, at its axial end, a connection part which can be connected to a pipe of another floor slab which is arrayed in the connection direction. In a lightweight floor slab construction method, two or more lightweight floor slabs are arranged side by side in the connection direction of the lightweight floor slab such that pipes of the lightweight floor slabs communicate with each other, pipes of adjacent lightweight floor slabs are connected to each other so as to connect the two or more lightweight floor slabs to each other. Here, two or more floor slab units which have two or more lightweight floor slabs connected together in the connection direction can be arranged and connected to each other.</p> |
