[0023] The following is in conjunction with the appendix Figure 1-8 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0024] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Steel wire rope is made of multiple strands of high-strength steel wires twisted together. Its tensile strength is far higher than that of fiber ropes or chains of the same diameter. It has the advantages of high strength, large load-bearing capacity, good toughness, strong impact resistance, high reliability, relatively long service life, and compact size. The multi-strand, multi-wire structure gives it good flexibility and elasticity, enabling it to withstand certain impact loads and vibrations. It is not prone to sudden breakage. The redundant design allows the overall structure to continue bearing loads for a period of time even if a few internal steel wires break (but timely inspection and replacement are required). Breakage is usually gradual and has a warning effect. As an important load-bearing component, steel wire rope is widely used in engineering, transportation, lifting, construction and other fields. It can withstand huge tensile loads and is particularly suitable for heavy-duty applications (such as cranes, elevators, cableways, ship mooring, etc.).

[0027] Reference Figures 1-8 As shown, this utility model provides a fall-prevention structure for a steel structure connecting corridor.

[0028] Example 1 Applied to steel structure corridors, the steel structure corridor includes a main structure 1, supports 2 and a corridor body 3, the supports are fixed on the main structure, and the two ends of the corridor body are placed on the supports on both sides. On both sides of the main body of the corridor, there are first connecting structures 4, steel wire ropes 5 and second connecting structures 6. The first connecting structure is fixed to the main structure, the second connecting structure is fixed to the side of the main body of the corridor, and the two ends of the steel wire rope are fixedly connected to the first connecting structure and the second connecting structure respectively.

[0029] Second connecting structures are fixedly installed on both sides of the main structure of the connecting corridor, serving as the first fixing points for connecting the steel wire ropes to the main structure of the corridor. A first connecting structure corresponding to the positions of the second connecting structures is also provided on the main structure, serving as the second fixing point for connecting the steel wire ropes to the main structure. Using the first and second fixing points, the two ends of the main structure of the connecting corridor are connected to the main structures on both sides by steel wire ropes.

[0030] Steel wire rope is used as a key component for fall protection. The multi-strand, multi-wire structure of steel wire rope gives it good flexibility and elasticity, enabling it to withstand certain impact loads and vibrations. It is not prone to sudden breakage.
