Description

Basement outer wall post-pouring strip waterproof structure Technical Field The utility model relates to the technical field of building walls, in particular to a basement outer wall post-pouring strip waterproof structure. Background The post-cast strip refers to a temporary strip-shaped gap reserved in a concrete structure in building engineering, and is mainly used for releasing stress through staged construction, preventing the structure from cracking and ensuring the integrity. When in construction, the main structures at two sides are poured firstly, the appointed width is reserved, and after deformation is stable, micro-expansion concrete is used for secondary pouring and sealing, and maintenance is enhanced. Since the structure and use of the basement determine the importance of waterproofing the basement, how to make the basement waterproof is a very important issue. In particular to a post-cast strip position, as a construction joint exists between the post-cast strip and the shear wall, and waterproof concrete is adopted for the basement and the post-cast strip, water can permeate preferentially from the construction joint between the post-cast strip and the shear wall during permeation, and the construction joint is a waterproof difficulty for the basement outer wall. In the prior art, the gap position of the post-pouring strip is subjected to waterproof treatment, and a water stop steel plate is additionally arranged to increase the water penetration path, so that the water stop steel plate is difficult to construct, is required to be welded with outer wall steel bars, is extremely easy to damage the outer wall steel bars, is difficult to seal, and is required to be cleaned for the second time after slurry leakage, so that the construction amount and the construction difficulty are increased. In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed. Disclosure of utility model In view of the above-mentioned drawbacks, the present utility model aims to provide a waterproof structure for a post-cast strip of an external wall of a basement, which can contact and seal a gap position of the post-cast strip by providing a sealing surface, and simultaneously provide a fixing piece, and fix and seal the post-cast strip and the sealing surface by the fixing piece, so as to ensure a waterproof effect of the gap of the post-cast strip. In order to achieve the aim, the utility model provides a basement outer wall post-pouring strip waterproof structure which comprises a wall body, a fixing assembly and a cover plate, wherein the post-pouring strip is arranged in the wall body, one side of the post-pouring strip protrudes out of the wall body, the fixing assembly is fixedly arranged on one side of the wall body, protruding out of the wall body, of the post-pouring strip, the cover plate comprises a cover plate fixedly arranged on the wall body, a groove is formed in the cover plate, the part, protruding out of the wall body, of the post-pouring strip is arranged in the groove, a side sealing piece is slidably arranged in the groove, and the cover plate and the side sealing piece are matched to seal the side wall of the part, protruding out of the wall body, of the post-pouring strip.
