Description

Technical Field

[0001] The utility model relates to a safety protection device for high-rise steel structure construction. Background Art

[0002] Most common steel structure construction requires on-site high-altitude operations. Therefore, in order to ensure the safety of on-site workers, safety protection measures must be set up. Most common on-site protection measures rely on the steel beams that have been hoisted, and the protection measures are directly connected to the existing holes of the steel beams or rely on the combination of clamps and vertical poles. The former has a small range of activities for workers due to the fixed position of the openings of the steel beams themselves, which is not convenient for construction; the latter has a too cumbersome installation process, involves on-site welding, and is not easy to disassemble after the construction is completed, and the protective device is difficult to reuse. To solve the above problems, the patent application number is CN202223583204.1, and the name is a steel structure operation protection device, which relies on the mechanical bite of the U-shaped fixing clamp and the connecting plate to achieve rapid assembly, relies on the vertical extrusion of bolts to achieve lossless connection with the steel beam, and forms an overall protection with the vertical pole and safety guardrail to provide safety for steel structure operations. The various components are connected by mechanical bite, without the need for additional welding or opening, and are easy to install.

[0003] Although the safety guardrails, poles, connecting plates and U-shaped clamps are dismantled in sequence after the steel structure construction is completed, and the disassembly is convenient, the overall protection formed by the poles and safety guardrails alone is too simple and the protection is too weak for the safety of the workers.
