Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an anti-climbing fence for a construction site. Background Art

[0002] Construction fencing refers to the measures taken to isolate the construction site from the external environment and make the construction site a relatively closed space, including walls built with various masonry materials, maintenance bodies made of various molded plates, etc. In construction projects, it is usually necessary to build fencing to enclose the construction area to isolate the road and ensure the safety of pedestrians and vehicles.

[0003] After searching, the patent publication number CN209339726U discloses a patent named an anti-climbing guardrail for buildings. The technical problem to be solved is that due to the integrated installation, it cannot be conveniently folded and stored and the placement location cannot be changed. It is not suitable for construction that needs to be moved and placed with the change of location. This guardrail can be folded and stored manually. Compared with the integrated guardrail with a fixed installation, it is more suitable for use in buildings and construction processes. It can be moved and placed according to the location of the construction and the placement location can be changed; but there are still the following drawbacks that need to be solved: the fence outside the building cannot effectively prevent people from climbing, which can easily cause losses to the construction site.
