[Problems to be solved by the device]

 In the above-mentioned conventional deck plate, due to the shape of the joints provided on both side edges, it is possible to oppose the force applied in the horizontal direction, but to the force applied in the vertical direction. Couldn't face enough. That is, these deck plates have a left-right length of about 60 cm to about 100 cm in FIG. 5, a length of about 10 m in the longitudinal direction (direction orthogonal to the paper surface in the figure), and their own weight. Also, there was a problem that the weight of the concrete placed on the top surface causes the deck plate to be separated up and down at the side edge. It is also conceivable that construction workers are working on this deck plate, and the side edges of the deck plate may separate during concrete pouring due to the weight of the worker. In order to solve this problem, after joining the side edges of these deck plates to each other, the fitting receiving portion 31 having an inverted V-shaped cross section and the fitting receiving portion 33 having an inverted U-shaped cross section are mounted on a tool. The edges of both sides were fixed by caulking. However, there remains a problem that the caulking work itself is very troublesome. Therefore, the present invention provides a deck plate that can sufficiently resist the force applied in the vertical direction at the side edges of the deck plates, which are the joints between the deck plates, and the caulking work described above. The issue is to eliminate the need for the.
