Description

Technical Field

[0001] This utility model relates to the field of safety rope installation technology in building construction, and more specifically, to a lifeline fixing bracket. Background Technology

[0002] The main dangers of working at heights for construction workers include falls from heights, being struck by objects, electric shock, and fire. These hazards can lead to serious bodily injury or even death, therefore strict safety measures must be taken when working at heights. Falls from heights are one of the most significant hazards in working at heights. Common causes of falls from heights include: falls from openings (if there are no safety measures at the opening or the measures are not secure), falls from scaffolding (if the scaffolding is not fully laid, the guardrails are damaged, or the distance from the wall is too great), falls from ladders (if a faulty ladder is used, the ladder is overloaded and breaks, or the ladder feet lack anti-slip measures), and falls from lightweight roofs (if workers are not wearing safety belts or accidentally step on a broken roof while working on a lightweight roof).

[0003] To prevent workers from falling from heights, life safety ropes are often used for safety protection. However, the commonly used fixing methods have problems such as insufficient stability and complicated installation. To improve the safety of workers on precast roof trusses, a life rope fixing bracket with a simple structure, easy installation, and stable and reliable stability is needed. Summary of the Invention

The first end of the two second support rods is perpendicularly connected to the first support rod, and the second end is provided with a connecting hole. The two ends of the adjusting screw are respectively connected to the connecting holes, forming a ring structure with the first support rod and the second support rod, which can clamp the building frame or beam in the form of a clamp. The first support rod is provided with a lifeline fixing ring for fixing the lifeline.

[0005] Preferably, both the first support rod and the second support rod are L-shaped angle steel.

[0006] Preferably, the second support rod is welded to the first support rod.

[0007] Preferably, the adjusting screw is provided with an adjusting nut and a double nut corresponding to the connecting hole. The adjusting screw passes through the connecting hole, and the double nut and the adjusting nut are screwed onto both ends of the adjusting screw and are located on both sides of the second support rod.

[0008] Preferably, an anti-slip pad is provided between the adjusting nut and the second support rod, and an anti-slip pad is also provided between the double nut and the second support rod.

[0009] Preferably, multiple lifeline fixing rings are arranged sequentially along the length of the first support rod to meet construction needs.

[0010] Preferably, the length of the first support rod is greater than the length of the second support rod.

[0011] Preferably, the fillet weld height at the weld joint between the second support rod and the first support rod is 5mm.
