Expansion joint capable of being locally and rapidly replaced

Abstract

The utility model relates to the field of expansion joints, and discloses an expansion joint capable of being locally and rapidly replaced, which comprises connecting section bars, concentric-square-shaped steel bars and an expansion joint water-stop belt, a plurality of concentric-square-shaped steel bars distributed at equal intervals are welded on the outward sides of the connecting section bars, the connecting section bars are oppositely designed and sequentially spliced end to end, and the expansion joint water-stop belt is connected with the expansion joint water-stop belt. An expansion joint waterstop is arranged between every two opposite connecting profiles, the expansion joint is divided into the multiple connecting profiles and the expansion joint waterstops, when the expansion joint needs to be replaced, only the connecting profiles and the expansion joint waterstops at the corresponding positions need to be detached, overall detachment is not needed, normal passing of a road or a bridge cannot be affected, and the expansion joint is convenient to use and high in practicability. The expansion joint is connected with the fixing steel bars and the L-shaped steel bars, and the fixing steel bars and the L-shaped steel bars are fixed to the road or the bridge in a pouring mode, so that the fixing effect of the expansion joint is better, only the local road or bridge needs to be cleaned during disassembly, and the replacement efficiency is improved.
