PROBLEM TO BE SOLVED: To provide a sealant between a bridge girder connection part and a slab which hardly causes lateral falling and positional displacement even if a force is added to the sealant in the lateral direction during positioning of a slab performed when mounting the slab on the sealant on the top surface of a bridge girder, and can obtain excellent sealability in a bridge girder connection part, simplify application work of a caulking agent, and reduce the used amount of the caulking agent when concrete or mortar is placed.SOLUTION: A sealant 10, which is installed between a bridge girder connection part and a slab arranged above a bridge girder and along the lengthwise direction of the bridge girder, is formed by laminating a lower foam 11 on an upper foam 21. The lower foam 11 has a hollow 18, which accommodates the end part 611 of a fastening member 61 projecting on a bridge girder connection part 53, under the undersurface, and the end part 611 of the fastening member 61 abuts against the undersurface of the hollow 18. |
