Description

Technical Field

[0002] When working at heights on construction sites, safety belts must be worn to ensure the safety of construction workers. Safety belts are generally hung and fixed on fixing devices or lifelines. In the actual construction process of high-altitude operations on the top of bridge piers, there is often a lack of fixing points or the fixing points are difficult to set up, resulting in many times that workers wear safety belts but do not wear them for high-altitude operations. They are not used correctly, which brings serious safety hazards to workers. Therefore, the safety belt fixing device used for high-altitude operations on the top of bridge piers is an important construction product. In the existing safety belt fixing devices used for high-altitude operations on the top of bridge piers, pre-embedded pad stone steel bars are used as safety belt fixing points to solve the problem of missing safety belt fixing points. Although this solves the problem of safety belt fixing, there is still no hanging position after the pad stone is poured, which cannot meet the safety belt fixing needs.
