As another technique, for example, Japanese Patent Laid-Open No. 2000-129848
As is known in the art described in the publication, there is also a construction in which a corrugated steel plate called a deck plate is laid on a beam member and light concrete is poured.

[0003]

By the way, it is a labor-intensive work to insert a joist between the beams or between the joists and the joists and to weld a steel plate to the joists. Further, when laying the deck plates, there is a problem that a gap is created on the surfaces where the deck plates are abutted. Therefore,
In the technique described in 2000-129848, an adhesive waterproof tape is adhered to the joint surface between the deck plate and the deck plate to fill the gap formed in the abutting surface. In addition, when installing and fixing the deck plate to the beam, the deck plate may be fixed to the beam with bolts or the like, which may require work from below the floor. In that case, scaffolding had to be provided under the floor, which was troublesome. An object of the present invention is to save the welding work of the floor slab,
To provide a floor slab joint structure and a floor slab joint method that can be easily joined, have no gaps on the abutting surface of the floor slab, and can be easily waterproofed.
