Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to a repairable and replaceable expansion joint. Background Art

[0002] A building expansion joint is a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion and contraction). The expansion joint divides the building components above the foundation, such as walls, floor slabs, and roofs (except wooden roofs), into two independent parts, so that the building or structure can expand and contract horizontally along the long direction.

[0003] When using traditional expansion joints, the steel bars are usually welded to the expansion joint body. During installation, the steel bars are installed and fixed on the bridge deck, wall and floor slab in combination with concrete. However, the expansion joints will deform or be damaged after long-term use and need to be replaced.
