Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an S-shaped buckle for closing a reserved hole. Background Art

[0002] In the process of modern building construction, the management of reserved openings is an important part of ensuring site safety and construction efficiency. Reserved openings are mainly used to meet the installation requirements of facilities such as smoke exhaust passages, ventilation shafts, electrical lines, and water supply and drainage pipes inside the building. These openings are pre-designed and reserved when the main structure is poured or built, so that subsequent professional subcontracting teams can access the corresponding systems. However, if the reserved openings are not closed in a timely and effective manner when not in use, it will pose a serious threat to the safety of the construction site.

[0003] Traditionally, temporary closure measures for reserved openings usually use wooden plywood, steel mesh or simple plastic sheeting. Although these materials are easy to obtain and install, they have significant safety hazards and shortcomings. First, due to the lack of a reliable fixing mechanism, this type of temporary closure material is easily displaced or fallen off due to external forces such as wind, people walking or material handling, causing the opening to be exposed again, increasing the risk of accidental falls for workers at heights, and objects may also fall from the opening, causing object impact injuries to workers below. Secondly, non-fixed closure materials are easily overlooked or forgotten to be restored, especially in frequent cross-operation environments, which greatly increases the difficulty of safety management. Therefore, the market is in urgent need of a safer, more stable and easy-to-manage reserved opening closure solution. Utility Model Content
