Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to an anti-falling net used for a building scaffold. Background Art
[0002] When carrying out building construction, scaffolding is usually used. When workers stand on the scaffolding to carry out construction, in order to prevent workers from falling and other objects from falling and injuring people, an anti-fall net is often fixed on the outside of the scaffolding. The existing anti-fall net mainly includes two parts: an external bracket and a protective net. Since the existing anti-fall net will become loose and not tight after long-term use, which will reduce the protective effect, the anti-fall net needs to be tightened regularly. Since no reminder mechanism is set on the outside of the existing anti-fall net, when the protective net in the anti-fall net becomes loose, it is not convenient for workers to find out in time and tighten it. Therefore, in view of the above problems, an anti-fall net for building scaffolding is proposed. Utility Model Content
