To provide means for improving positioning workability for road bridge floor slabs to greatly absorb errors of dimensions and relative positions inherent in the road bridge floor slabs and on-site errors at joint sites, thus enabling a reduction of working time for joining the road bridge floor slabs while achieving good workability and good working efficiency to actualize manpower saving.SOLUTION: A joint for connecting a pair of road bridge floor slabs includes receiving members arranged on the road bridge floor slabs, and erection members for connecting the receiving members, respectively, the receiving member each having a bottomed storage part, and an engaging part for engaging with the erection member inserted into the storage part, the erection members each having a pair of insertion parts to be inserted into the storage part, and a bridge part for bridging the insertion parts. The insertion part has a cylindrical shape of which the cross section is approximately uniform, and the outer diameter of the insertion part is smaller than the inner diameter of the storage part.SELECTED DRAWING: Figure 12 【課題】道路橋床版同士の位置決め作業性を向上させ、また道路橋床版に内在する寸法、相対位置等の誤差や接合現場における現場誤差等を大きく吸収することが可能で、施工性が良好で且つ作業効率が良く、よって省人化を図ることを可能としながらも、道路橋床版同士の接合の作業時間を短縮可能とする手段を提供する。【解決手段】道路橋床版に配される受部材と、受部材同士を連結する架設部材とを有して一対の上記道路橋床版を連結する継手であって、受部材は、有底の収容部と、収容部に挿設される架設部材に係合する係合部とを有し、架設部材は、収容部に挿設される一対の挿設部と、該挿設部間を繋ぐ架橋部とを有し、挿設部は、横断面形状が略一様の筒形状を有し、挿設部の外径が、上記収容部の内径未満である。【選択図】図１２
