Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a temporary protective device for a reserved opening in a floor slab. Background Art

[0002] During the construction process, it is usually necessary to reserve openings in the floor slabs. In order to ensure the safety of construction workers and pedestrians, temporary protective devices are needed to cover the openings before installing cover plates and other components. Currently, most of the openings are covered with wooden boards, steel plates and other panels. However, the pressure-bearing capacity of wooden boards is insufficient. They are easily deformed or even broken after being compressed, and their safety performance is poor. Generally, they can only be used for smaller openings. Steel plates have a greater pressure-bearing capacity and can be used for larger openings, but the size of steel plates is fixed and cannot be flexibly applied to openings of different sizes.

[0003] The existing application number is 202222257410.7, which is a floor reserved hole protection device, including a protection plate, a fixing bolt movably connected to the top of the protection plate, a reserved hole is provided on the top of the protection plate, a rolling bearing is fixedly connected to the top of the protection plate, two rolling bearings are movably connected to the rotating shaft, a cover plate is fixedly connected to the surface of the rotating shaft, a handle is fixedly connected to one end of the cover plate, a baffle is fixedly connected to the side of the reserved hole, and a handle groove is provided on the top of the protection plate. The floor reserved hole protection device has the following deficiencies:

[0004] 1) The size of the protective plate is fixed. For reserved openings of different sizes, protective plates of corresponding sizes need to be set, which has poor adaptability and high cost;

[0005] 2) The protective plate needs to be fixed to the floor slab by bolts. On the one hand, it is convenient to disassemble and assemble. On the other hand, it is necessary to open installation holes on the floor slab for the bolts to penetrate, which destroys the structure of the floor slab. Utility Model Content
