Treating the leakage of roof deformation joints has become an important aspect of improving the quality of roof waterproofing projects.
[0003] Since the roof deformation joint will produce deformation and is a part prone to leakage, it is necessary to strengthen the waterproof measures at this position. At the same time, the existing water isolation belts for waterproofing will age after being used for a certain period of time. If they cannot be replaced in time, it may affect the waterproof effect of the deformation joint. The installation of the traditional leakage prevention mechanism for the water isolation belt makes it more complicated to replace the water isolation belt, and it is not convenient to quickly remove the water isolation belt.

[0006] With the above structural design, the pressing plate can prevent the cam from directly contacting the water isolation belt, prevent the cam from scratching the water isolation belt and damaging the surface of the water isolation belt during rotation, and the return spring can prevent the pressing plate from detaching. The return spring can also make the pressing plate and the U-shaped clamping plate clamp the water isolation belt. The loading and unloading of the water isolation belt are more convenient, and at the same time, the sealing of the deformation joint is ensured.
