[0060] like Figures 2 to 4 As shown, in this embodiment, the first corner gusset plate 1114 frame 1110 includes a first corner gusset plate rod 1111 fixedly connected to the first corner horizontal frame 1106 and the first corner straight support frame 1109, and a first corner upper fixing rod 1112 and a first corner lower fixing rod 1113 respectively fixedly connected to the upper and lower ends of the first corner gusset plate rod 1111, and the second corner gusset plate 1214 frame 1210 includes a second corner gusset plate rod 1211 fixedly connected to the second corner horizontal frame 1206 and the second corner straight support frame 1209, and a second corner upper fixing rod 1212 and a second corner lower fixing rod 1213 respectively fixedly connected to the upper and lower ends of the second corner gusset plate rod 1211, wherein the first corner lower fixing rod 1113 is hinged to the second corner lower fixing rod 1213.

[0061] Specifically, first corner gusset 1114 is made of thick steel plate and is fixedly connected to first corner gusset rod 1111, first corner upper fixing rod 1112, and first corner lower fixing rod 1113 by welding. First corner gusset 1114 provides an additional support surface for corner device 1001, increasing the load-bearing capacity and protection range of the structure, and can effectively prevent people and objects from falling.

[0062] The second corner gusset plate 1214 is made of the same material and manufactured using the same process as the first corner gusset plate 1114, and is fixedly connected to the second corner gusset plate rod 1211, the second corner upper fixing rod 1212 and the second corner lower fixing rod 1213, and cooperates with the first corner gusset plate 1114 to form the protective surface of the corner device 1001.

[0065] Among them, at least one corner fixing hole 1303 for passing the corner steel cable 1301 and multiple corner limiting holes 1304 for passing the elastic corner limiting rope 1302 are provided on the first corner gusset plate 1114 and the second corner gusset plate 1214.

[0066] Specifically, the corner connection device 1300 is interposed between the first and second gussets 1114, 1214, providing both connection and cushioning. Corner cables 1301 are constructed from high-strength steel wire rope, offering superior strength and wear resistance. Connecting the first and second gussets 1114, 1214, via specialized rigging, the cables provide the primary connecting force, ensuring the two corner components maintain a relatively stable positional relationship while articulating.

[0067] Elastic corner retaining cords 1302, made of natural or synthetic rubber, are threaded through multiple corner retaining holes 1304 on the first and second gussets 1114, 1214. When the structure is subjected to external impact, the elastic corner retaining cords 1302 elastically deform, absorbing some of the energy and acting as a buffer, minimizing damage to the structure. Furthermore, the elastic corner retaining cords 1302 limit excessive displacement of the corner assembly, ensuring the overall stability of the structure.

[0068] like Figures 5 to 7 As shown, in this embodiment, the support plate frame 1409 includes a support plate rod 1410, a support upper fixed rod 1411 and a support lower fixed rod 1412 fixedly connected to the support horizontal frame 1405 and the support straight frame 1408, and the support plate 1415 is fixedly connected to the support plate rod 1410, the support upper fixed rod 1411 and the support lower fixed rod 1412.

[0069] Specifically, support plate 1415 is made of thick steel plate and is fixedly connected to support plate rod 1410, support upper fixing rod 1411, and support lower fixing rod 1412 by welding. Support plate 1415 provides a large support surface for the fall prevention structure, increasing the structure's load-bearing capacity and protection range, and can effectively prevent people and objects from falling.

[0070] like Figures 1 to 7 As shown, in this embodiment, at least one support fixing hole 1413 for passing the fixing steel cable 2001 and multiple support limiting holes 1414 for passing the elastic limiting rope 2002 are provided at the relatively distant end of the first gusset plate 1114 and the second gusset plate 1214 and at both ends of the support plate 1415.

[0071] Specifically, the connecting unit 2000 is responsible for connecting adjacent corner devices 1001 and support devices 1002, as well as adjacent support devices 1002, to form a complete protection system. The fixing cables 2001 are made of high-strength steel wire rope, which has high strength and rigidity. Using specialized rigging, the fixing cables 2001 connect adjacent corner devices 1001 and support devices 1002, as well as adjacent support devices 1002. These cables can withstand significant tensile forces, ensuring the integrity and stability of the entire structure.

[0072] Elastic limiter ropes 2002, made of natural or synthetic rubber, are threaded through support and limiter holes 1414 in the first gusset plate 1114, the second gusset plate 1214, and the support plate 1415. When the structure is subjected to external forces, the elastic limiter ropes 2002 elastically deform, providing a buffer and position-limiting effect, preventing damage from excessive deformation. Furthermore, the elastic limiter ropes 2002 can adjust the structure's position to varying degrees, adapting to varying operating conditions.

[0073] In some embodiments (not shown in the figures), the support fixing holes and the support limiting holes are not directly set on the first gusset plate and the second gusset plate, and the support plate. The support fixing holes and the support limiting holes can be set on the external sleeve, and the external sleeve can be sleeved on the first gusset plate and the second gusset plate, and the support plate.
