In addition, the PC plates are arranged in the width direction over multiple spans,
A technique of a floor slab in which a PC plate is tensioned and integrated in a width direction by a steel wire to form a bidirectional plate has been already disclosed in Japanese Patent Application No. 6128855. Since the PC plate is tensioned and integrated in the width direction, the vertical load acting on the floor slab is transmitted to the girders on the four circumferences, and the in-plane rigidity of the floor surface required during an earthquake is guaranteed.

が、従来の技術では次のような問題点があった。In the case of constructing a floor made of PC plates in which the longitudinal direction of a rectangular PC plate is passed between the beams, and a large number of spans are lined up in the width direction, the floor of the PC plates is placed above the beams. There is a gap where the PC plate cannot be placed. Concrete is placed in this gap to integrate the PC plate and the beam, but the conventional technique has the following problems.

い鉄筋コンクリート梁の場合に大きい。(A) When the concrete with a gap formed on the upper part of the beam is first cast and the PC steel wire penetrating in the width direction of the PC plate is tensioned after the strength of the concrete is generated, the PC plate and the beam are integrated. Since the tension is applied to the places, the tension is transmitted to the beams on the four circumferences, and as a result, in order to obtain a certain tension compression force on the PC plate, a large tension considering the force transmitted to the beams is required. . This effect is particularly great in the case of reinforced concrete beams with a large cross section.

煩雑になる。(B) After tensioning the PC plate with the PC steel wire penetrating in the width direction, when attempting to place concrete in the gap formed in the upper part of the beam, the PC plate is continuously stretched before the PC steel wire is tensioned. A block or the like for fixing is required, and the work becomes complicated.

By placing concrete in the gap between the matching PC plates and making the PC steel wire penetrate through the sleeve embedded in the PC plate over the above-mentioned several spans, the PC steel wire is tensioned and integrated to form the PC plate. The floor slab structure will consist of a PC plate that can withstand the load in both the longitudinal and width directions.

The PC plate is laid across the longitudinal direction of the C plate and spans several spans in the width direction of the PC plate, and the steel frame beam and the embedding plate embedded in the PC plate are welded to each other at the upper part of the steel frame beam and adjacent to each other. A stud bolt was welded onto the steel beam in order to secure the anchoring of the concrete placed between the PC plate and the PC plate, and was embedded inside the PC plate so as to penetrate the width direction of the PC plate over several spans. Tensioned PC steel wire is wired to the sleeve, concrete is placed in the gap between the adjacent PC plates on the upper part of the steel beam, and after the strength of the concrete is generated, the PC steel wire of the PC plate over the several spans at once. Tension, adjust the level of the upper surface of the PC plate as necessary, and process the tension end with filling mortar or the like.

版への圧縮力の導入が容易である。[Function] In a floor slab made of a PC plate that is a bidirectional plate applied to a steel-framed beam, the PC plate that is placed over multiple spans in the width direction of the PC plate is placed in the gap above the beam after concrete placement. Since the PC plate and the beam are integrated because they are tense at a time, there is no need for a block or the like for continuously and fixing the PC plate members. Part of the tension force is also transmitted to the reinforced concrete beam, but the cross-sectional area of the beam is smaller than that of the reinforced concrete beam, so the force transmitted to the beam is also small and PC
Easy to introduce compressive force to the plate.
