Description

Technical Field

[0001] The utility model relates to the technical field of post-cast strips, in particular to a waterproof structure of a post-cast strip of a basement. Background Art

[0002] The post-cast joint is a concrete strip with a certain width reserved in the structure and poured after a certain period of time to adapt to the influence of factors such as environmental temperature changes, concrete shrinkage, and uneven structural settlement. After the concrete on both sides of the post-cast joint in the basement is poured, the post-cast joint has a placement period. During the placement period, the post-cast joint needs to be protected to prevent debris and sewage from entering the post-cast joint and affecting the later pouring of the post-cast joint.

[0003] After searching the Chinese patent with the announcement number CN214994117U, a basement post-cast joint waterproof structure is disclosed, which includes a waterproof cover plate and an inner formwork of the post-cast joint. The waterproof cover plate and the inner formwork of the post-cast joint are respectively attached to the outer side and the inner side of the outer wall. The side wall of the waterproof cover plate is provided with a threaded screw, which passes through the outer wall and is fixed to the inner formwork of the post-cast joint by a nut. The side wall of the waterproof cover plate facing the inner formwork of the post-cast joint is provided with a positioning component, and the positioning component is configured as a plurality of positioning rods. The outer wall is preset with a plurality of positioning slots corresponding to the positioning rods one by one, and the positioning rods are plugged into the positioning slots.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing concrete surface after forming is not very flat, resulting in gaps between the waterproof cover plate and the concrete on both sides of the post-casting strip, which makes it easy for sewage to enter the post-casting strip through the gaps, affecting the later pouring of the post-casting strip.
