ていた。"Problems to be Solved by the Invention" However, in the method of constructing slab B using the composite slab structure 1, the bottom plate 4 forming the bottom plate of slab B, the steel frame 2 serving as the slab structure, and the reinforcing steel 3 are integrated to form the composite slab component 1, however, the upper end reinforcement 12 is not integrated with the composite slab component 1 due to the simplicity of the work, and the on-site arrangement is difficult. It was left to muscle. Therefore, in the slab B construction work, the construction period required for the upper end reinforcement 12 reinforcement work becomes a factor that influences the length of the entire construction period, and also
There was an additional point that needed to be taken into consideration, which was that the efficiency of +R construction work was not promoted. In particular, when the multi-slab structure 1 is enlarged, the entire construction period becomes longer due to the upper end = 12 reinforcement work, and when openings are provided in the slab to be constructed, this The work of reinforcing bars to be placed around the openings must also be done manually on site, resulting in a longer construction period. Therefore, the realization of a composite slab structure that is integrated including the upper end reinforcement 12 has been awaited.

。A plurality of upper end reinforcements 12 are provided between the upper ends of each of the spacers 13 so as to extend substantially parallel to the lower end reinforcements 3a, and these upper end reinforcements 12 are temporarily attached to the spacer 13 by welding, wire, etc. It's stopped. In addition, these upper end muscles 1
2, a plurality of intersecting reinforcing bars 14 are arranged at intervals in the length direction of the upper end UJ 12 in the same way as the lower end reinforcement 3a.
Moreover, it is arranged so as to intersect with these upper end reinforcements 12. Each intersection of the upper end reinforcing bars 12 and the cross reinforcing bars 14 is temporarily fixed by wire, welding, or the like. Here, the distance between the upper end reinforcements 12 and the steel frame 2 may be appropriately determined in advance according to construction conditions such as the thickness of the slab to be constructed.

ブの構築方法。(2) A plurality of steel frames made of section steel are arranged in parallel with each other with their flanges facing downward, and a spacer extending in the length direction of these steel frames is attached to the upper end of each of the steel frames. A bottom plate is installed between the flange parts of the lower part of the steel frame to cover these gaps, and a plurality of lower end reinforcements are installed above these bottom plates by passing through the web parts of each of the steel frames, and these lower end A plurality of crossed reinforcing bars are attached to intersect with the reinforcing bars, and the plurality of upper end reinforcing bars and the plurality of crossed reinforcing bars crossing these are assembled together to form a lattice-shaped reinforcing bar, and the upper end is attached between the upper ends of the spacer. A composite slab structure is formed by arranging the lattice reinforcing bars so that the reinforcing bars extend substantially parallel to the lower end reinforcements, and this composite slab structure is mounted on the upper part of the preceding frame that has been constructed in advance. 1. A method for constructing a slab, which comprises constructing a slab on top of the preceding framework by placing concrete so as to cover the composite slab structure.
