る。(Function) As described above, in the present invention, a PC floor slab, which protrudes above the entire upper part of the lattice assembly reinforcement embedded in the concrete slab and has a cotter on the outer peripheral surface of the intaglio slab, is installed between the girders. The concrete is placed on the upper part of the lattice-like assembly bars, and the same PC slab is also used as a grading frame, and the concrete is poured between the PC slab and adjacent PC slabs on the beam. The cotter 1 is integrated with the PC floor slab through the protruding part, and is arranged on the outer peripheral surface of the PC floor slab when it is on a 9-beam beam.
- Integrate with poured concrete, PC floor slab, and girder through.
