Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to an anti-seepage structure of a post-cast belt of a basement. Background Art

[0002] The post-cast strip is a concrete strip left at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications to prevent harmful cracks that may be caused by uneven shrinkage or settlement of the structure during construction. However, the connection area between the post-cast strip and the outer wall of the basement is limited, and the anti-seepage structure is simple, which greatly reduces the anti-seepage effect. Moreover, after backfilling, the compressive strength of the post-cast strip connection may be insufficient, thereby failing to ensure the stability of the anti-seepage structure of the post-cast strip.

[0003] For example, announcement No. CN217078875U discloses a basement post-cast strip anti-seepage structure, which includes an outer wall and a reinforcement member, wherein the outer wall is vertically arranged on the ground, the reinforcement member is arranged in the outer wall, a casting cavity is left on the outer wall, one end of the reinforcement member extends into the casting cavity, and a post-cast strip is cast in the casting cavity; a reinforcement part is provided on the side of the outer wall away from the basement; a caulking joint connected to the casting cavity is left on the reinforcement part, and an anti-seepage member is installed on the side of the caulking joint away from the basement.

[0004] It can be seen from the above-mentioned public scheme that the connection between the post-cast strip and the outer wall is sealed and waterproofed by the set reinforcement part and the anti-seepage piece. Its structure is simple and the anti-seepage effect may not be good. In addition, the post-cast strip is supported by the reinforcement piece and the reinforcement part, and its supporting strength may be insufficient, thereby failing to ensure the stability of the anti-seepage structure of the post-cast strip.
