Description

Building Lifting Fence

technical field

The utility model relates to the related field of building construction safety guardrails, in particular to building lifting guardrails.

Background technique

Guardrail is a common protective equipment, especially for building construction. As a kind of isolation device during building construction, it can isolate the construction site from the surrounding area to prevent outsiders from accidentally entering. During building construction, ensuring the safety of construction workers is a must. Setting up construction fences is one of the important links in building construction.

The existing building guardrails are very cumbersome to assemble, which leads to cumbersome disassembly in the later stage. At the same time, the height adjustment of the existing guardrails is inconvenient. Most of them use positioning plug-ins and positioning holes of the guardrail support frame to adjust the height of the guardrail. There is a lot of labor, and the practicability of the protective height adjustment of the guardrail is poor; in addition, the existing guardrail is not easy to move, which increases the labor input, and the wind and other conditions are likely to cause safety hazards.

The Chinese utility model patent with the application number 202011503791.1 discloses an easy-to-lift building construction guardrail and its installation method. The above-mentioned patent records that when in use, the guardrail needs to be raised by a lifting mechanism, but the upper part is the guardrail, and the lower part is the guardrail. It is a lifting device, so the lower part cannot be protected, which has great limitations and reduces work efficiency.
