It is possible for this overhanging portion to play a role as a substitute member for the bottom slab that was conventionally made of cast-in-place concrete. As a result, there is no need for bottom slab formwork or concrete placing work at the site, making it possible to shorten the construction period and gradually reduce construction costs. Since the side wall on the side where the overhanging portion is provided has an opening, the space formed inside the tubular member and the space between the tubular members formed on the overhanging portion are different from each other. The communication is established via the opening.
