Abstract

The invention discloses a scaffold fastener slipping alarm device comprising a limiting device and a warning device; the limiting device comprises an E-shaped sleeve fixed on an end of a cross bar through a first buckle; the limiting device comprises an U-shaped sleeve fixed on a side surface of a vertical rod through a second buckle; the warning device comprises a first warning device and a second warning device which are in parallel connection with a power supply; two sets of touch control switches are in parallel and are in series connection with the power supply and a second warning device; four sets of pressure switches are in parallel and are in series connection with the power supply and the first warning device; The invention also discloses an installation method for the scaffold fastener slipping alarm device. Glass beads of the installation method effectively protect the relative position of the E-shaped sleeve and the U-shaped sleeve; the invention provides a step alarming scheme, which effectively solves the problem that there is no warning device for the scaffold fastener slipping. The installation method of the invention has the advantages of clear steps and easy operation. The invention effectively solves the problem that there is no warning device for the scaffold fastener slipping.

Description

technical field [0001] The invention belongs to the field of construction engineering safety devices, in particular to a sliding alarm device for scaffold fasteners. Background technique [0002] At present, scaffolding is widely used in building construction, but there are currently overloaded frames, unqualified frame tubes or fasteners, irregular erection, etc., and the level of external frame construction is uneven. [0003] On October 8, 2011, at the construction site of Kaixuan Building in the northern suburbs of Xi'an, a cantilevered scaffolding of a 30-story high-rise under construction collapsed. Buried pressure, 7 of them died on the spot and 5 were injured. [0004] On November 19, 2012, Jiangsu Fengyi Construction and Installation Engineering Co., Ltd. had a local scaffolding collapse accident during the concrete pouring construction of the two-story building in Xingbing Town, Qianchaohu City. 9 workers were buried, and 6 workers died and 3 were injured on the ...
