[0002] Steel structures are often used in high-rise and super high-rise buildings to enhance the safety and stability of the structure or for gorgeous shapes, such as steel trusses, steel corridors, etc. Steel structures are also used in some special buildings. In actual construction sites, workers often encounter situations where the safety belt has no suspension belt, the suspension point is not firm, it is not convenient to tie the safety belt, or only one-side wire rope is installed for workers to tie. This leads to great safety hazards for steel structure installation workers during the construction process, which not only increases the safety hazards at the construction site, but also puts great pressure on the project management team.

[0003] The Chinese patent application with publication number CN113187258A discloses an assembled portable double-buckle safety railing assembly and its assembly method, including a guardrail column, a first horizontal U-shaped clip, a first fastening mechanism, a second horizontal U-shaped clip and a second fastening mechanism. The assembly method is to install the guardrail column on the first horizontal U-shaped clip and then install it to the upper flange on one side of the H-shaped steel beam through the first fastening mechanism, and then fix the second horizontal U-shaped clip between the guardrail column and the upper flange on the other side of the H-shaped steel beam through the second fastening mechanism. Although this prior art can effectively reduce the difficulty of installing and constructing high-altitude guardrail columns, improve the efficiency of installing and constructing guardrail columns, reduce the difficulty and workload of later disassembly operations, and improve the overall construction efficiency, it still only installs a single-side wire rope for operators to hang, which poses a safety hazard, and its railing lacks flexibility and cannot be moved, and cannot meet the needs of different construction site passage directions. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a movable safety guardrail and construction method which has a simple structure, is easy to assemble and disassemble, is flexible to move, can form a complete safety passage, provides double-sided steel wire ropes for workers to hang on, reduces safety hazards, is reusable, and has a wide range of applications.
