Only by reasonably setting the lifeline and firmly fastening the safety belt to the lifeline can the lifeline's fall prevention function be brought into play. The current technology includes the method of welding steel sections on steel beams to set lifelines. Welding causes damage to the steel structure, and the steel sections need to be cut later, which cannot be used in a turnover manner. The economy and aesthetics are poor. There is also a method of welding the lifeline column to the U-shaped base and fastening the U-shaped base and the steel structure with bolts. This method has the risk of the bolts being easily loosened and the U-shaped base and the steel structure falling off, and the reliability is low. There is also a method of drilling holes in the flange of the main beam of the steel structure and connecting the column base to the steel structure with bolts. However, drilling holes in the steel structure has an adverse effect on the stress of the structure, which requires the consent of the designer.

In view of this, it is necessary to invent an adjustable and detachable lifeline setting method for steel structure roofs, improve the safe use factor, turnover rate and construction efficiency of the lifeline, save costs, and solve the above problems. The utility model lifeline fixing device provides an adjustable and detachable lifeline setting method for steel structure roofs, which aims to improve the safety, economy and applicability of steel structure lifeline devices, reduce the risk of high-altitude falling accidents during steel structure high-altitude operations, and ensure the safety of high-altitude operations.
