Adjustable elevator shaft opening anti-falling platform

Abstract

The invention discloses an adjustable elevator shaft opening anti-falling platform, the length of a plurality of square steel main keels is adjustable, one end of each square steel main keel is connected with an L-shaped embedded part, the L-shaped embedded parts are embedded before opening concrete pouring, and the other ends of the square steel main keels abut against a wall and are obliquely arranged; a plurality of secondary keel battens are connected to the square steel main keel in a clamped mode, a surface layer formwork is arranged on the top faces of the secondary keel battens, the square steel main keel and an L-shaped embedded part can be rotationally installed through a locking bolt, and after the square steel main keel and the L-shaped embedded part are rotationally installed in place, gaskets on the two sides are added for bolt connection. The ends, close to the wall, of the square steel main keels are wrapped and nested through end anti-skid rubber pads, end friction can be increased, damage to the wall can be reduced, the included angle between the whole anti-falling platform and a floor ranges from 5 degrees to 10 degrees, the ends of the square steel main keels make contact with the wall, an angle is formed, large friction force is generated, and the anti-falling effect is improved. Therefore, the friction force and the anchoring section are jointly stressed to maintain the stability of the whole anti-falling platform.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an adjustable anti-falling platform at the entrance of an elevator shaft. Background technique [0002] In the process of building construction, some temporary elevator shaft openings are easily generated during the structural construction process, causing safety hazards, and the original protection method requires the use of unfinished anti-fall platforms for high-altitude operations when operating, which is very prone to safety accidents . [0003] Moreover, the traditional anti-fall platform at the entrance of the elevator shaft is erected in the way of steel pipe and wood, which has the problem of waste of erection materials, and at the same time, there are problems such as difficulty in later recovery and low construction efficiency. Contents of the invention [0004] The purpose of the present invention is to provide an adjustable anti-fall platform at the ...

Problems solved by technology

[0002] In the process of building construction, some temporary elevator shaft openings are easily generated during the structural construction process, causing safety hazards, and the original protection method requires the use of unfinished anti-fall platforms for high-altitude operations when operating, which is very prone to safety accidents

[0003] In addition, the traditional anti-fall platform at the entrance of the elevator shaft is erected in the way of steel tube and wood, which has the problem of waste of erection materials. At the same time, there are problems such as difficulty in later recovery and low construction efficiency.
