Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a protective device for a settlement post-casting belt. Background Art

[0002] In building construction, post-settlement joints are set up to solve the problem of difference in settlement between the main building and the podium of a high-rise building. The post-settlement joints can only be poured after the main structure construction is completed and the settlement is basically stable.

[0003] However, at the construction site, the settlement post-casting strip is generally exposed for a long time. The steel bars in the post-casting strip are often damaged due to long-term exposure and the movement of construction workers. The steel bars in the post-casting strip are seriously rusted and even disconnected, which seriously weakens the structure. Most of the existing technologies use formwork to seal the settlement post-casting strip. However, the use of formwork sealing method not only makes it difficult to splice the formwork, but also has the risk of collapse during waterproofing and vehicle passing during construction. If construction is carried out in the rainy season, it is also very easy to affect the basement waterproofing project, affect subsequent construction, and cause construction delays.
