Background

The building expansion joint is also called an expansion joint, and is a structural joint arranged along a proper position in the direction of a building or a construction joint of the building to prevent the structure from cracking or damaging due to thermal expansion and cold contraction caused by climate and temperature change of the building components. The expansion joint divides building components above a foundation, such as a wall body, a floor slab, a roof and the like into two independent parts, so that the building or the structure can horizontally expand and contract in the extension direction. In the building wall, a waterproof structure is required to be arranged at the corresponding position of the expansion joint of the building wall to prevent water leakage and water seepage.

At the present stage, only a waterproof gasket is usually installed for waterproofing the expansion joint to prevent the expansion joint from being waterproofed, but water still flows into the expansion joint along the gap at the bottom of the waterproof backing plate, and the waterproof gasket is easy to separate from the top of the expansion joint, so that a good waterproof effect cannot be achieved.
