The expansion joint of a building, namely an expansion joint, is a structural joint which is arranged at a proper position along the direction of a building or a construction joint of a structure in order to prevent the structure from generating cracks or damages due to the change of climate temperature (thermal expansion and cold contraction). The expansion joint divides building components such as wall, floor, roof (except wood roof) above foundation into two independent parts, so that the building or structure can horizontally expand and contract along the length direction.

The roof of the house is usually provided with expansion joints for preventing the roof from generating cracks due to climate change, and the roof is positioned at the top of the house and can drop into the house once water leakage occurs. In order to prevent the roof expansion joint from leaking, the prior art generally embeds or pastes the waterstop in the expansion joint, but can play a waterproof role, but because the roof expansion joint is positioned on the roof, the roof expansion joint is subjected to sun-drying rain and thermal expansion and contraction for a long time, the waterstop is easy to age and leak at the junction of the waterstop and the roof concrete, so that the roof is water-permeable and water-permeable.
