Description

Technical Field

[0001] The utility model relates to the technical field of building anti-leakage, in particular to an anti-leakage structure for expansion joints on roofs of public buildings. Background Art

[0002] A roof expansion joint refers to 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 changes in climate and temperature. The expansion joint divides the building components above the foundation, such as walls, floor slabs, and roofs, into two independent parts, so that the building or structure can expand and contract horizontally along the long direction to prevent cracks in the house due to climate change. On rainy days, rainwater often leaks into the expansion joints of the roofs of public buildings, which has become a common quality problem with a high incidence rate, seriously affecting the use function. The subsequent maintenance workload is large and difficult to repair, and the repeated maintenance rate is high.

[0003] At present, public buildings are prone to leakage at the base of the retaining walls on both sides of the roof expansion joints and at the expansion joint cover plates of the retaining walls on rainy days. When there is water accumulation on the roof, the accumulated water is easy to penetrate into the room through the expansion joints, affecting the living function. At the same time, affected by temperature stress, the retaining walls are prone to shrinkage and deformation, resulting in adjacent roof panels not being on the same horizontal line, so that rainwater can more easily leak into the expansion joints, seriously affecting the residents' living. In addition, most of the existing expansion joint covers are fixed, and it is not easy to replace them when they are damaged, which easily causes the roof to expand and contract, thereby reducing the practicality of the device. Summary of the invention

[0004] The utility model aims to provide an anti-leakage structure for expansion joints on the roof of a public building, so as to solve the problems raised in the above-mentioned background technology.
