Hole protection safety supporting device for civil engineering construction

Abstract

The hole protection safety supporting device for civil engineering construction comprises a first protection plate and a second protection plate, a sliding plate is fixedly connected to the second protection plate, an elastic cushion is fixedly connected to the upper surface of the sliding plate, and the sliding plate is slidably connected with the first protection plate; the first protection plate is provided with an installation cavity used for being connected with the sliding plate, and the lower surface of the first protection plate and the lower surface of the second protection plate are both fixedly connected with supporting columns which are vertically arranged. And a rotating shaft is rotationally installed on the first protection plate, a gear is fixedly connected to the rotating shaft, and a rack plate used in cooperation with the gear is fixedly connected to one side of the sliding plate. According to the device, the common protection area of the first protection plate and the sliding plate can be rapidly and accurately adjusted, holes of different sizes can be protected according to actual conditions, the protection effect on the holes of different sizes is good, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a hole protection safety support device for civil engineering construction. Background technique [0002] In the process of civil engineering construction, there are often some openings in the construction. The horizontal opening is a major source of danger. Whether its protection is in place directly affects the safety management of the project and the personal safety of workers. Therefore, it is necessary to use the opening protection safety support device Protect it. [0003] Due to the currently used hole protection safety support device, it is inconvenient to quickly and accurately adjust the area of ​​the protective plate, so it is impossible to protect the holes of different sizes according to the actual situation, resulting in the protection effect of the holes of different sizes. Poor, low practicality. SUMMARY OF THE INVENTION [0004] The purpose o...

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. Due to the currently used hole protection safety support device, it is inconvenient to quickly and accurately adjust the area of ​​the protection plate, so that it cannot be well adjusted according to the actual situation. The protection of large and small openings leads to poor protection effect and low practicability for different sizes of openings, and a kind of opening protection safety support device for civil engineering construction is proposed
