Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a construction safety belt hanging platform. Background Art

[0002] When working at height during bridge construction, construction workers often need to work near the edge, facing a greater risk of falling. At the same time, in the absence of necessary protective measures, working at height will cause workers to have a certain fear, which will have an adverse impact on the quality and progress of the project. Therefore, providing construction workers with better safety protection measures is a good way to promote high-altitude construction of bridge projects.

[0003] Safety belts are safety devices used to prevent falls from heights. Currently, after wearing safety belts, construction workers tie them to a secure tie-down point to ensure their safety. However, during bridge construction, it is often difficult to find a convenient and secure tie-down point on the bridge deck, and when construction workers move to the next construction site, they need to find a new tie-down point, which reduces construction efficiency.
