Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated cover plate for advanced sealing of a post-cast zone of a basement structure. Background Art

[0002] The post-cast joint of the basement structure is a temporary construction joint set up to prevent harmful cracks in the cast-in-place reinforced concrete structure due to uneven shrinkage and settlement. The post-cast joint needs to be closed some time after the main structure construction is completed, and this period can be as long as several months. The prefabricated cover plate for pre-sealing the post-cast joint of the basement structure is a specially designed prefabricated component used to close the post-cast joint in advance during the construction of the main structure, so as to shorten the construction period and improve construction efficiency.

[0003] At present, in construction projects, especially basement construction, post-cast joints are used to ensure the integrity and stability of the structure. However, the post-cast joint treatment method requires a long time to be completely closed, which directly affects the subsequent construction process, backfill and garden landscaping projects. Although this method effectively guarantees the quality of the building, it has limitations in construction efficiency.

[0004] After searching, the Chinese patent announcement number: CN218779533U discloses a prefabricated cover plate for pre-sealing the post-cast strip of the basement top plate settlement, including a post-cast strip and a cast-in-place plate. The outer surface of the cast-in-place plate is provided with a connecting structure for the post-cast strip. The connecting structure includes a bottom cover plate and a top cover plate movably arranged on the outer surface of the cast-in-place plate. The upper surface of the bottom cover plate is provided with an adjustment structure for fixing the top cover plate. The upper surface of the bottom cover plate is provided with a sealing structure for sealing the post-cast strip. The prefabricated cover plate for sealing the post-cast strip of the basement top slab settlement in advance is installed and fixed by fixing the bottom cover plate, then fitting the top cover plate with the upper surface of the cast-in-place slab, and then rotating the support rod. At this time, the clamping block is displaced and extended to the inside of the second installation groove, thereby fixing the top cover plate, and being able to seal post-cast strips of different thicknesses, achieving the advantages of good practicality and being able to seal post-cast strips of different thicknesses. However, the existing technology has high maintenance costs and cumbersome supporting structures, which increases construction difficulty and safety hazards, and a long curing time, which delays the overall project progress. The existing technology has the problems of long sealing cycle, limited material selection and difficulty in adapting to rapid construction needs. When rushing to meet deadlines, the defects are particularly prominent, which seriously affects the progress of the entire project. Utility Model Content
