After searching, the patent with application number 202120988910.0 discloses a safety anti-fall device for building construction, which includes at least three support columns, and a connecting rod is provided between two of the support columns. The connecting rod includes a sliding end and a rotating end. The rotating end of the connecting rod is rotatably connected to one of the support columns, and the sliding end of the connecting rod is slidably connected to another support column. The top walls of the support columns are commonly connected with an anti-fall net.

[0003] However, during actual use, the applicant found that in the process of catching falling objects through the anti-fall net, some of the falling objects that fell on the anti-fall net were easy to bounce upwards and bounce around in no direction, which could easily cause certain injuries to people around the anti-fall net. In view of this, we proposed a safety anti-fall device for building construction. Utility Model Content
