PRECAST FLOOR SLAB AND BRIDGE
PROBLEM TO BE SOLVED: To provide a precast floor slab and a bridge of using the same, capable of removing foam, while sufficiently filling a secular curable material buried to be joined with a main girder.SOLUTION: A precast floor slab 40 of applying the present invention comprises a lower end surface 41 provided above a main girder 30 and oppositely provided to an upper flange 31 of the main girder 30 and an insertion hole 42 penetratingly formed upward from the lower end surface, and the lower end surface 41 comprises a taper part 45 inclined so that a height becomes higher as approaching the insertion hole 42 toward the bridge axial direction X of the main girder 30, and the taper part 45 is provided in a plurality in the bridge width direction Z.SELECTED DRAWING: Figure 8
【課題】主桁と接合するために埋め込まれる経時硬化性材の十分な充填が可能であり、気泡の除去が可能であるプレキャスト床版及びこれが用いられる橋梁を提供する。【解決手段】本発明を適用したプレキャスト床版４０は、主桁３０の上方に設けられるものであって、主桁３０の上フランジ３１と対向させて設けられる下端面４１と、下端面から上方に向けて貫通させて形成される挿入孔４２とを有し、下端面４１は、主桁３０の橋軸方向Ｘに向けて挿入孔４２に近づくにつれて高さが高くなるように傾斜したテーパー部４５を有し、テーパー部４５は、橋幅方向Ｚに複数に設けられる。【選択図】図８
