る。 This rib forming member 10 is installed in a formwork in a factory or construction site with a reinforcing bar truss (Mitsuko truss) 11 and a PC for introducing prestress.
After arranging the steel materials 12 at appropriate positions, concrete is placed at the bottom of the reinforcing bar truss 11, and prestress is introduced by the prestressing steel materials 12 using the bond construction method. Here, the reinforcing bar truss 11 is formed by combining a corrugated reinforcing bar 13, two long reinforcing bars 14, and a large number of short reinforcing bars 15, as shown in FIG.

Stirrup reinforcements 1 surrounding these beam main reinforcements 17
8 and a beam component 20 consisting of hairpins 19
After horizontally installing the beam forming member 20 and fixing the beam formwork 21 around the beam forming member 20, a large number of rib forming members 10 are placed between the beam forming members 21 at appropriate intervals (for example,
Hang them at 50cm intervals.

ブの構築作業が完了する。 Next, between these rib forming members 10, an intervening member 22 such as wood is placed in the missing portion 10b of the rib forming member 10, and a flat floor forming form 23 is installed on the upper surface of this intervening member 22. A welded wire mesh 24 is laid on the upper surface and concrete C is poured to construct a floor beam surface. Further, after the concrete hardens and develops concrete strength, the intervening member 22 and the floor forming form 23 are removed to complete the construction work of the ribbed slab.

In this case, the rib forming member 10 supported by the beam formwork 21 passes the floor forming formwork 23 through the intervening member 22.
Since this construction method supports the rib forming member 10 and the floor forming formwork 23, no shoring is required.
Furthermore, since the rib forming member 10 is manufactured using a bond method, a long rib forming member 10 may be manufactured and then cut to a predetermined size as appropriate for use.

素化等を計ることができる。"Effects of the Invention" As explained above, the present invention manufactures a concrete rib forming member equipped with a reinforcing bar truss in advance, and after supporting a floor forming formwork with this rib forming member via an intervening member, Since the ribbed slab is constructed by pouring concrete and removing the intervening members and floor forming formwork after the concrete has hardened, the intervening members and floor forming formwork, which have a simple structure, are installed and removed on site. Ribbed slabs can be easily constructed by simply constructing a ribbed slab, and the rib-forming members supported by the beam formwork support the floor-forming formwork through intervening members, so shoring for the rib-forming members and the floor-forming formwork is not required. It is possible to streamline work at the site, save labor, and simplify the management of parts without the need for additional equipment.
