Claims

[Claims for Utility Model Registration] 1. In forming an expansion joint by interposing a watertight sealing member between floor slabs and holding both sides of the sealing member with fitting members provided on the floor slab side, the said fitting The member is characterized in that it is formed by a shell member consisting of a top plate and a support plate joined to the lower surface of the top plate, and a holding member attached to the shell member and having opposing bent portions for receiving end portions of the seal member above and below. Expansion joint for bridges. 2. The expansion joint for a bridge according to claim 1, wherein a shell member is formed by attaching a J-shaped support plate to the lower surface of the top plate. 3 Extensions are provided on the lower end side of the support plate, and cuts formed in these extensions expand on both sides and form engagement parts with the concrete. The expansion joint for bridges according to any of Item 2. 4. The expansion joint for a bridge according to claim 1 of the utility model registration, in which a connecting plate that engages with concrete is attached to the intermediate portion of the supporting plate. 5. The bridge according to claim 1 of the utility model registration claim, in which a shell member consisting of a vertical support plate attached to the center of the top plate and a bottom plate attached to the lower end of the support plate is used between the seal members. expansion joints.
