Description

Technical Field

[0001] The utility model relates to the technical field of safety fences, in particular to a base structure of a safety fence in a construction area. Background Art

[0002] Steel structure has the characteristics of light weight, high strength, easy manufacturing, short installation period, etc., so it has been widely used in various fields. However, it also has great safety hazards. When carrying out floor construction, the construction period is long and the number of construction workers is large. If there is no safety protection on the edge, it is very easy to cause construction workers to fall and get injured.

[0003] In the actual construction process, due to the simple steel structure frame, the edge safety fence is not easy to fix. Some construction sites temporarily tie it to the steel structure, and the structural effect is poor. Some construction sites cast the fence into the building when pouring the edge, but it cannot provide protection for the entire floor construction process, and it is time-consuming and labor-intensive to remove it later, and the remaining voids require additional processing. Due to the above factors, most construction sites do not provide edge safety protection or only provide simple temporary protection.

[0004] To this end, we propose a base structure for a safety fence in a construction area. Utility Model Content
