Description

Technical Field

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

[0002] Post-poured joints are temporary construction joints at corresponding positions of foundation slabs, walls or beams during construction to prevent harmful cracks that may be caused by uneven temperature and shrinkage in reinforced concrete structures. The structure is temporarily divided into several parts. After a certain period of internal shrinkage of the components, concrete is poured into the construction joints to connect the structure into a whole.

[0003] After searching, a Chinese patent discloses a basement post-cast strip structure (authorization announcement number CN110090120A), which includes an outer wall and a post-cast strip arranged on the outer wall; it also includes a plurality of mounting plates installed at intervals on the outer side of the outer wall and located at the position of the post-cast strip, and a protective plate is connected between two adjacent mounting plates through a sliding connection structure. The mounting plates and the protective plates together constitute the protective structure of the post-cast strip. Although this patented technology can form the protective structure of the post-cast strip with the mounting plates and the protective plates through modular assembly, not only is the construction more convenient and labor-saving; the mounting plates and the protective plates can be reused, which can reduce construction costs and is more environmentally friendly.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that a large number of fastening screws and fastening nuts are required in the above basement post-cast strip structure, but this connection method is relatively cumbersome to operate. There is a lack of a mechanism in the post-cast strip structure that can quickly connect with the protective plate, resulting in the existing connection method requiring the screwing of multiple fastening nuts, which is very inconvenient and prone to the fastening nuts falling off and being lost.

[0010] As a preferred embodiment, a spring is fixedly connected to the middle of the inner wall of the U-shaped mounting frame, circular grooves are equidistantly provided inside the protective plate, and one end of the spring contacts the inner wall of the circular groove.
