BEARING MEMBER AND BEARING STRUCTURE FOR PRECAST CONCRETE FLOOR SLAB OF STEEL BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a bearing member for concrete floor slabs of a steel bridge, with which the durability of the floor slabs can be enhanced and which ensures the vibration control effect and sound isolating effect. SOLUTION: A bearing member 7 is installed between steel girders 10 and floor slabs 13 of precast concrete to be laid on the girders. The bearing member 7 is composed of a soft rubber piece 7a for flatness adjustment to be contacted with the oversurface of steel girder 10 and a hard rubber piece 7b for adjusting girder deflection which is joined with the soft rubber member and in which a curved surface convex upward is formed on the contacting surface with floor slab 13.
