To provide means allowing workability for work including relative position determination upon joining bridge floor slabs to each other to be improved by means of a simple structure.SOLUTION: A joint for bridge floor slabs is provided with: a pair of fitted parts arranged on a pair of floor slabs of a bridge adjacent to each other, respectively; a pair of fitting parts fittable in the fitted parts; and a joint member having a cross-link part connecting between the pair of fitting parts, wherein the cross-link part has a through hole penetrating along a fitting direction of the fitting parts, being provided with a shaft part inserted into the hole and an abutting body rotatable with the shaft, and a positioning mechanism is formed between the fitted part and the fitting part such that the fitting part is positioned corresponding to the fitted part when the fitting part is fitted into the fitted part as rotation of the abutting body is limited through engaging the fitted part in a circumferential direction after the abutting body rotates with the shaft part to a predetermined angle.SELECTED DRAWING: Figure 1
【課題】簡易な構造によって、橋梁の床版同士を接合させるときの相対的な位置決めを含めた作業性を向上させる手段を提供する。【解決手段】橋梁の隣接する一対の床版にそれぞれ設けられる一対の被嵌入部と、上記被嵌入部に嵌入し得る一対の係合部及び該一対の係合部間を繋ぐ架橋部を有する連結部材と、を具える橋梁床版継手であって、上記架橋部は、上記係合部の嵌入方向に沿って貫通する孔を有し、上記孔に挿通する軸部と、上記軸部と共に回転可能な当接体とを具え、上記当接体は、所定角度まで上記軸部と共に回転した後、上記被嵌入部と周方向に係合して回転が規制され、上記被嵌入部に上記係合部が嵌入するとき、上記係合部が上記被嵌入部に対して位置決めされるように、上記被嵌入部と上記係合部との間に、位置決め機構が形成される。【選択図】図１
