Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a protective structure for post-pouring strips. Background Technology

[0002] Post-cast strips are concrete strips left at corresponding positions in foundation slabs, walls, and beams during building construction to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven shrinkage or settlement, in accordance with design or construction specifications. Post-cast strips are widely used in concurrent construction, which involves multiple tasks being carried out simultaneously, with one sub-project being carried out in an overlapping manner with another. For example, during the main structure concrete construction, the masonry work of the secondary structure is inserted. This construction method makes full use of space and time, minimizing or even completely eliminating construction interruptions, thereby accelerating the construction progress and reducing costs.

[0003] When pouring existing basement floors, a post-pouring strip is required. However, because the post-pouring strip exists for a long time, a large amount of construction waste may fall into it during overlapping construction. Moreover, the construction waste that falls into the post-pouring strip is difficult to remove, requiring a lot of manpower for cleaning, which reduces the construction speed and increases the construction cost. In addition, the existing basement floors have poor waterproof performance, which may cause water seepage during actual use, resulting in a damp basement. Utility Model Content
