Box-type portable edge protection fence for construction site safety management

Abstract

The invention discloses a box-type portable temporary edge guardrail for construction site safety management. The box-type portable temporary edge guardrail has the following two structures: (1) the box-type portable temporary edge guardrail is composed of at least one temporary edge guardrail; if a plurality of temporary edge guardrail units need to be connected, the temporary edge guardrail units are sequentially connected through columns; each temporary edge guardrail unit is composed of a box body and a telescopic net assembly connected with the box body; the telescopic net assembly can be unfolded in a lifting manner and can also be contracted and stored in the box body in a pressing manner; (2) the box-type portable temporary edge guardrail is composed of at least one temporary edge guardrail; if a plurality of temporary edge guardrail units need to be connected, the temporary edge guardrail units are sequentially connected; each temporary edge guardrail unit is composed of a box body and a telescopic net assembly connected with the box body; the telescopic net assembly can be unfolded in a lifting manner and can also be contracted and stored in the box body in a pressing manner. The box-type portable temporary edge guardrail provided by the invention is convenient to mount and dismount, and can be conveniently applied to the construction site to ensure the safety.

Description

technical field [0001] The invention belongs to the technical field of protective devices for building construction, and relates to a protective fence, in particular to a box-type portable border protective fence for safety management on a construction site. Background technique [0002] As we all know, the field of construction engineering is a high-risk industry, and various safety accidents occur from time to time; those shocking scenes remind people all the time that safe production is the guarantee of happiness. In many accidents (such as: electric shock, mechanical injury, object strike, collapse, high-altitude fall and other accidents), the incidence of high-altitude fall accidents accounts for about 40% to 50%. It can be seen that high-altitude fall is the most important cause of safety accidents. one of the reasons. [0003] During the construction process, every construction worker is faced with the safety problem of "four ports and five borders". The so-called "...

AI Technical Summary

Problems solved by technology

There are two main types of traditional guardrails at the edge of openings: the first one is the guardrail built with fasteners of construction steel pipes. The bar and the cross bar are connected by fasteners, which consume a large amount of steel; the specification of the steel pipe is 3.85kg / m, and the specification of the fastener is 1.25kg / piece; and the cross bar as a border protection, its bearing capacity requires It is not high. According to the JGJ80-91 safety technical specification for building construction work at heights, the length of the border protection cross bar is 2m, and the load-bearing requirement is 1000N. However, the steel pipe with a diameter of 48*3.5MM currently used has a strength far exceeding Use requirements lead to waste of materials, and the cost of steel structure guardrails is high, the transportation cost is high, and the temporary construction is unsightly in appearance, which cannot achieve standardization, standardization, and batch production.

The second type of guardrail is to use square steel pipes and safety nets together, and it can also be used as diagonal braces or fixed with short steel pipes; due to the different sizes of the openings of doors and windows, it will cause troubles in the selection of material sizes, and the installation and disassembly are more complicated and cannot be disassembled Recombination and assembly for recycling, resulting in waste of resources

Different processes, different time, the installation and removal of the protective railings are not only time-consuming and labor-intensive, but sometimes the protective railings are not restored after being dismantled at will, which will cause the edge openings to lose their protection and bury hidden dangers for safe construction

[0005] Generally speaking, the above two traditional border fences have the characteristics of cumbersome process steps, high cost, poor versatility and low recovery rate, which are far from the goals of energy saving, emission reduction, cost reduction and efficiency increase advocated by the current state.
