Description

Technical Field

[0001] The utility model relates to a reusable edge protection fixing device. Background Art

[0002] The protection of openings and edges among the three treasures, four openings, and five edges has always been the focus of safety protection on construction sites. In traditional protection schemes, due to changes in construction procedures, opening size and position and other conditions, the protection forms are diverse and the installation and disassembly workload is large; untimely and unstable recovery is also the cause of the high incidence of safety accidents of falling from heights. First, the guardrail fixing device is installed on the front of the wall and should not be disassembled and assembled at any time, resulting in many items being skipped in the later processes and more finishing work; second, the guardrail fixing device is installed on the side of the opening, and the later processes need to be repeatedly disassembled and installed, which is cumbersome to operate. Third, during the construction process of mobile protection, the elevator shaft safety guardrail is moved arbitrarily by humans, which is easy to cause protection loss. Utility Model Content
