Description

Technical Field

[0001] This invention relates to a protective railing for the edge of a building construction floor. Background Technology

[0002] The increasing number of falls from heights during construction each year underscores the growing importance of safety precautions. Effective protection measures for openings and edges can significantly reduce the occurrence of such accidents. Therefore, we must emphasize the role of safety equipment in protecting the lives of construction workers. However, current edge protection components, such as temporary steel pipe railings erected on construction sites, suffer from drawbacks such as long installation times and poor safety, leaving the safety of on-site workers unsecured.

[0003] Chinese patent application CN201720017702.X describes an adjustable, novel, stable edge protection fence assembly, comprising several support rods and a protective net, with the protective net positioned between any two support rods. Each support rod includes an upper tube, a lower tube, and a fixing pin. The upper tube is fitted inside the lower tube. The upper tube has several first adjustment holes distributed on its side wall, and the lower tube has a second adjustment hole on its upper side wall. The fixing pin is inserted into both the second and first adjustment holes of the lower tube. Several hanging rings are fixed to the side wall of the lower tube. Several hooks are fixed to both sides of the protective net at positions corresponding to the hanging rings on the lower tube, and these hooks engage with the hanging rings on the support rods on either side. This patent uses an adjusting nut and a fixing pin to finely adjust the relative length between the upper and lower tubes. However, the adjusting nut can only be manually rotated, which is inconvenient. The adjustment range of the nut is limited, and the nut is prone to loosening after prolonged use, potentially posing a safety hazard. Summary of the Invention
