Safety anti-falling device for building engineering

Abstract

The invention discloses a safety anti-falling device for building engineering, and relates to the technical field of foundation pit barriers. The safety anti-falling device solves the problems that anexisting foundation pit anti-falling device cannot flexibly shrink and deform, the overall volume of the device is large, and transportation and storage are not convenient. The safety anti-falling device for the building engineering comprises a center supporting pipe, a positioning ring and an ejecting pressing ring, wherein three external threads are arranged on the outer wall of the circumference of the central supporting pipe in an upper and middle and lower interval mode, thirty clamping plates in a circle is supported by and welded to the bottom section of the central supporting pipe ina ring array, and a base ring is welded and fixed to the periphery of the circle of the clamping plate; and a sliding ring is welded and fixed to the center of the positioning ring, and the positioning ring is arranged on the central supporting pipe in a sleeving and sliding mode through a sliding ring. According to the safety anti-falling device for the building engineering, the positioning ringcan be conveniently lifted to open and close a rain-shielding umbrella through an inserting frame, and the inserting frame can be inserted into the positioning ring through the selective insertion ofthe upper and lower groups of inserting holes, so that the rain-shielding umbrella is kept in an open or contracted state.

Description

technical field [0001] The invention relates to the technical field of foundation pit barriers and building protection, in particular to a safety anti-drop device for construction engineering. Background technique [0002] As a safety measure tool for the construction site of the construction project, the safety fence of the foundation pit of the construction project is an indispensable tool for the entire construction activity. It is mainly responsible for isolating the construction site of the foundation pit from the outside world, ensuring the safety of the outside world, and preventing non-staff from entering the site. Thereby played the role of safety protection. [0003] For example, the patent No. CN201620909454.5 discloses a construction engineering foundation pit safety fence, including a first bracket, a cross brace, a second bracket, a third bracket, a composite plate, a connecting groove, a connecting rod, and a left clip. Buckle, right buckle, window, window be...
