BACKGROUND OF THE INVENTION In order to attach a slab of a steel building, a corrugated deck plate having a desired strength is usually laid.
Furthermore, concrete is poured on top of it.
At this time, the deck plate is approximately 60 cm in width × several meters in length and 1.6 mm in thickness, and is fixed by welding or the like with its lower surface placed on the upper flange of the beam. By the way, as shown in FIG. 7 (a), the beam 10 'of the steel building is connected by bolting via a splice plate 11a' at a joint or a column in the middle of the beam 10 '. At the splice portion 11 ', the splice plate 11a' and the bolt 11b 'further protrude from the torsion surface of the upper flange 10a' of the beam 10 '. Therefore, when laying the deck plate 12 ', the deck plate 12' is cut off at the splice portion 11 ', and the support plate 2' is separately welded only to that portion as shown in FIG. The plate 12 'was to be supported.

[0003] This work is mostly performed on site, and is extremely troublesome because the support plate 2 'is welded while being kept horizontal. This was a factor in cost increase. Of course, it is possible to weld such a support plate 2 'at the stage of steel frame processing in advance, but it is difficult to perform the splicing work by overworking and unnecessary overhang from the flange at the time of splicing work. Most of the work was done on site.

Further, as shown in FIG. 7 (b), when driving concrete 14 'onto deck plate 12', deck plate 12 'cut at splice portion 11' has a large opening 13. The concrete 14 'leaks from here to the downstairs. Conventionally, a cloth adhesive tape 16 or the like is applied to the opening 13 as shown in FIG. 7 (a), and concrete 14 'is poured after the opening 13 is closed, so to speak, and this is an improvement. There was room.
