Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of construction safety protection, and particularly relates to a folding protection net bag with a turning plate. BACKGROUND

[0002] At present, the safety protection of the outer wall construction of the building industry in China is facing severe challenges. Due to the structural compatibility defects in the design of the traditional scaffold system, most projects are difficult to simultaneously set up the anti-falling net bag of the building outer wall in the main construction stage. This contradiction is mainly caused by the low matching degree of the scaffold vertical rod spacing, the horizontal rod arrangement and the anti-falling net fixing node, the insufficient bearing capacity of the outer end of the cantilever scaffold, and the space conflict between the climbing scaffold system and the anti-falling net installation, and other technical bottlenecks.

[0003] Due to this restriction, the construction unit has to adopt the passive scheme of “first dismantling the scaffold body and then installing the protection”, which leads to a significant increase in construction cost. More seriously, the lagging installation makes the suspended operation surface lose the falling buffer protection, causing the disconnection between the safety protection and the construction progress, and bringing about the hidden danger of construction operation.
