Description

Technical Field

[0001] The utility model relates to the technical field of building floor protection, in particular to a temporary protection fence for a horizontal opening of a building floor. Background Art

[0002] In the construction of civil buildings, when the reinforced concrete main frame of each floor is completed, the horizontal openings of the floors have no structural enclosure, and accidents such as people and objects falling are prone to occur at the horizontal openings of the floors, so temporary protection must be provided for the horizontal openings of the floors. However, during the construction of civil buildings, the demand for guardrails is very large, and guardrails need to be frequently installed and disassembled, which is very time-consuming; and the existing guardrails are fixed by welding and other methods, so they need to be dismantled by destructive means, which is not conducive to repeated use.

[0003] A temporary guardrail for horizontal openings on floors of civil buildings disclosed in the Chinese utility model patent application disclosure CN206539046U is designed and manufactured using steel sections and has a latch-type movable rod that allows for easy and convenient installation and removal of the guardrail, which can be reused after removal, thereby effectively reducing construction measures and investment costs. The guardrail is uniformly sized according to the size of each horizontal opening on each floor, thereby reducing the number of guardrail specifications and facilitating use. The guardrail has uniform specifications, is beautiful, neat, and safe, and improves the effect of civilized construction. However, the temporary guardrail for horizontal openings on floors of civil buildings has the disadvantages of being inconvenient to carry, install, and use, and its height is not easy to adjust during use.
