Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a safety rope fixing device for a steel structure box beam. Background Art

[0002] Steel structures are particularly common in construction projects, especially high-rise steel structures. During their construction, there are many operations at heights and high safety risks. Installers need to walk on steel beams, and there is nowhere to hang safety belts, which poses a safety hazard. Most of the commonly used devices are H-shaped steel beam safety rope fixing devices. When encountering steel structure box girders, the safety rope is directly tied to the steel beam, and the safety belt cannot play the role of high hanging and low use. The fixed bracket is welded on the steel beam, and welding and cutting cause damage to the steel structure. In addition, installation and disassembly are not convenient. Therefore, in order to solve such problems, we proposed a steel structure box girder safety rope fixing device. Utility Model Content
