Description

Technical Field

[0001] The utility model relates to the technical field of temporary protective railings for safe construction, in particular to temporary protective railings for prefabricated curved stand panels in comprehensive sports stadiums. Background Art

[0002] The comprehensive sports stadium's grandstand panels utilize prefabricated curved slabs. The standard area of these prefabricated curved stands primarily encompasses the spectator seating area, allowing for standardized design techniques to facilitate production and reduce costs. The prefabricated bare concrete stands rely on the main structure for load transmission, with bolts providing a secure connection between the main structure and the prefabricated stands. Four shear connectors are installed between the upper and lower adjacent slabs, along with grouting holes spaced 2 meters apart. These are anchored by pins to these holes, enhancing the coordinated load-bearing performance of adjacent slabs.

[0003] During the hoisting process, due to the non-construction of the upper row, edges appeared on the site, which did not meet the on-site safety protection requirements. With the traditional protective enclosure construction, it was necessary to fix the curved prefabricated stand panels with expansion screws, which damaged the finished curved prefabricated stand panels. In the process of transporting the finished protective enclosure, the curved prefabricated stand panels were also easily damaged, resulting in a large workload for repairing the bare concrete in the later stage. In addition, the extensive use of finished protective enclosures also increased the cost of safe and civilized construction. Utility Model Content
