JOINT STRUCTURE BETWEEN CORRUGATED STEEL WEB AND SUBFLOOR PLATE IN CORRUGATED STEEL WEB BRIDGE
To provide a suitable joint structure between a corrugated steel web and a subfloor slab including a precast subfloor slab member in a corrugated steel web bridge.SOLUTION: A joint structure 18 between a corrugated steel web 5 and a subfloor slab 6 includes: a lower flange 6 of the corrugated steel web 5; a precast subfloor slab member 11 placed on the lower flange 6; a flat steel plate 21b fixed on the upper surface of the lower flange 6; a first reinforcing bar protruding from a corrugated steel plate 8 of the corrugated steel web 5; a second reinforcing bar 23 protruding from the precast subfloor slab member 11; third reinforcing bars 23 and 24 placed above the second reinforcing bar 23 and protruding from the precast subfloor slab member 11; and a cast-in-place concrete part 12 burying the flat steel plate 21b and the reinforcing bars. The second reinforcing bar 23 includes a loop portion 23b that at least partially overlaps the flat steel plate 21b when viewed from the bridge axis direction. The first reinforcing bar and the third reinforcing bar 24 form a lap joint.SELECTED DRAWING: Figure 6
【課題】波形鋼板ウェブ橋における波形鋼板ウェブとプレキャスト下床版部材を含む下床版との好適な接合構造を提供する。【解決手段】波形鋼板ウェブ５と下床版６との接合構造１８は、波形鋼板ウェブ５の下フランジ６と、下フランジ６に載置されたプレキャスト下床版部材１１と、下フランジ６の上面に固定された平鋼板部２１ｂと、波形鋼板ウェブ５の波形鋼板部８から突出する第１鉄筋と、プレキャスト下床版部材１１から突出する第２鉄筋２３と、第２鉄筋２３よりも上方に配置されてプレキャスト下床版部材１１から突出する第３鉄筋２３，２４と、平鋼板部２１ｂ及びこれらの鉄筋を埋設する場所打ちコンクリート部１２とを備える。第２鉄筋２３は、橋軸方向から見て少なくとも部分的に平鋼板部２１ｂに重なるループ部２３ｂを含む。第１鉄筋と第３鉄筋２４は、重ね継手を形成する。【選択図】図６
