Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a waterproof structure of a top plate deformation joint. Background Art

[0002] At present, buildings often deform under the influence of external factors, resulting in cracks or even damage. The structural joints reserved for this situation are called deformation joints. Deformation joints are often reserved during the construction process. Deformation joints can absorb or buffer the stress caused by factors such as temperature difference, settlement and vibration, and reduce the deformation and cracking of buildings. The setting of deformation joints must meet the dual requirements of conforming to the deformation of the structure and sealing and waterproofing. According to different design concepts, deformation joints are divided into three types: expansion joints, settlement joints and seismic joints.

[0003] There are many existing methods for dealing with expansion joints. In most designs and constructions, waterstops are often embedded or finished expansion joint waterproof structures are used. After the embedded waterstop is constructed, the rubber waterstop is prone to lose its waterproof function due to excessive shear or axial deformation, poor protection, long-term use and aging, and because most cases are embedded in advance during construction and cannot be replaced, there is a lack of effective repair methods in the later stage; therefore, finished expansion joint waterproof structures are gradually widely used. Finished expansion joint waterproof structures are usually directly installed in the expansion joints, and can be replaced in time if they are damaged.

[0004] The above-mentioned existing technical solutions have the following defects: the finished expansion joint cover plates basically have fixed specifications, and due to construction errors during the construction of the expansion joints, the expansion joint structures of fixed specifications need to be processed twice before they can be used at the construction site, which prolongs the construction period of the expansion joint waterproof structure.
