PROBLEM TO BE SOLVED: To provide a floor slab connection structure capable of preventing a buried joint from being damaged on a bridge having the buried joint.SOLUTION: A pair of floor slab ends 13a, 14a of a bridge forms: a first joint gap S1 between girder ends 10a, 11a or between the girder end and a bridge abutment; and a second joint gap S2, which is narrower than the first joint gap S1 and located above the first joint gap and faces the first joint gap. A bridge comprises: the pair of floor slab ends; a pavement 22, which is consecutively installed on the floor slab ends 13a, 14a; and a buried joint 21, which is formed as a part of the pavement 22 in predetermined length range across the second joint gap S2. The floor ends 13a, 14a are connected by a hinge structure 20 that allows vertical rotation of the floor slab ends.SELECTED DRAWING: Figure 1
【課題】埋設ジョイントを有する橋梁において、埋設ジョイントの損傷を防止することができる床版連結構造を提供する。【解決手段】桁端部１０ａ，１１ａ間又は桁端部と橋台との間に形成される第１遊間Ｓ1の上方に、互いに対向して第１遊間Ｓ1よりも小さい第２遊間Ｓ2を形成する１対の床版端部１３ａ，１４ａと、床版端部１３ａ，１４ａ上に連続して敷設される舗装２２と、第２遊間Ｓ2を跨いだ所定長さ範囲にわたり舗装２２の一部として形成される埋込みジョイント２１とを有する橋梁において、床版端部１３ａ，１４ａ間を該床版端部の鉛直方向回転を許容するヒンジ構造２０で連結したことを特徴とする。【選択図】図１
