PRECAST FLOOR SLAB CONNECTION PART STRUCTURE AND CONNECTION PART CONSTRUCTION METHOD
To provide a precast floor slab connection part structure capable of improving work efficiency and significantly shortening a construction period as compared with a conventional precast floor slab connection structure.SOLUTION: A connection part structure that connects a plurality of precast floor slabs 1 installed on a bridge girder, in which connection ends 10 of the precast floor slabs 1 which face each other comprise, at the least, joint reinforcements 3, and a notch recess 11 having a prescribed height at a top end of the connection end 10. A connection top member 2, having substantially the same thickness as the prescribed height and having strength to withstand a wheel load of a vehicle, is bridged to the notch recesses 11 of the precast floor slabs 1 facing each other. A main pavement 5 is paved over the connection top member 2.SELECTED DRAWING: Figure 6
【課題】従来のプレキャスト床版の接続構造に比べて作業効率を向上させるとともに、工期を大幅に短縮することが可能な、プレキャスト床版の接続部構造を提供する。【解決手段】橋桁上に設置される複数のプレキャスト床版１を接続する接続部構造であって、互いに対向する前記プレキャスト床版１の接続端部１０は、継手鉄筋３と、該接続端部１０の天端部に所定の高さを有する切欠き凹部１１とを、少なくとも備え、互いに対向する前記プレキャスト床版１の前記切欠き凹部１１には、前記所定の高さと略同じ厚さを有するとともに、車両の輪荷重に耐える強度を有する接続天端部材２が架け渡され、前記接続天端部材２の上方には本設舗装５が舗設されることを特徴とする。【選択図】図６
