It is well known that a deck plate 1 which is a corrugated steel sheet as shown in FIGS. 6 and 7 is used. This deck plate 1 is laid between beams, and slab reinforcing bars 2 are arranged on it,
When the concrete 3 is cast, a concrete slab can be constructed, and the concrete slab is a discarded formwork. Since a support or the like for supporting the slab formwork is not required, temporary materials can be largely omitted.

[0003] By the way, it is very difficult to attach a sleeve to the deck plate 1 because the bottom surface of the deck plate 1 is corrugated. In the case of a paper round sleeve for a pipe called a so-called void, the paper cylinder is set in a vertical position, and its lower end is cut or deformed into a corrugated shape according to the bottom corrugated shape of the deck plate 1 and attached. In the case of a rectangular shape such as a duct, the lower end of a formwork veneer plate, a thin iron plate or the like is cut into a wave shape and attached.

[0004]

As described above, conventionally, when a sleeve is conventionally attached to a deck plate,
It is necessary to cut the sleeve component into a corrugated shape and to assemble a plate-shaped member, which is very troublesome.
