Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a leak-proof structure for a deformation joint between a corridor and a main building. Background Art

[0002] Since the main building usually has a large single-layer area, and corridors are often set up to connect different single-body areas, when the building length exceeds a certain limit, the building plane changes frequently, or the single-layer area is large, deformation joints are often set at the structural change parts to disconnect the building. Therefore, the deformation joints in the corridor part are very common. And the corridor is often set as a covered corridor or an open-air form, and there will be different degrees of water accumulation in the corridor, and the accumulated rainwater will gather towards the deformation joint. Usually, the indoor floor deformation joint practice here is the water-blocking principle to prevent water from leaking down. Over time, the rainwater accumulates here and damages the water stop belt, resulting in leakage, which affects the space under the corridor. Summary of the Invention
