[0030] In response to the above problems, an embodiment of the present application provides a steel structure ladder for crossing a retaining wall. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 A steel structure ladder for crossing a retaining wall is shown, comprising:

[0032] The side support 1 comprises a triangular frame 11, a stand 12 and a connecting rod 16. The triangular frame 11 is welded into a right-angled triangular frame by a square tube, and two of the right-angled sides of the triangular frame 11 are symmetrically arranged and connected by the connecting rod 16. The whole side support connected together is shown in Figure 2 The middle part is left as a reversed U-shaped groove, which is buckled on the retaining wall during use to play a positioning role, so that the whole side support 1 is horizontally arranged on the retaining wall. The application further comprises a protective fence 2 and a non-slip steel plate 3.

[0033] The side support 1 and the protective fence 2 are symmetrically arranged as two, each connecting column 22 is connected with the hypotenuse of the triangular frame 11 of the side support 1, the non-slip steel plate 3 is arranged on the top and hypotenuse of the two side supports 1, and the connecting rod 17 is detachably connected and arranged between the right-angled sides of the two triangular frames 11 by screws to fix the two side supports 1.

[0034] In this way, the non-slip steel plate 3 is arranged and fixed between the two side supports 1 to form a ladder, and then the ladder is buckled on the retaining wall, so that the workers on both sides can climb over the retaining wall through the ladder. The height of the whole ladder can be designed according to specific needs. The two sides of the ladder are also provided with the protective fence 2, which is safer. The device has simple structure, is easy to assemble and disassemble, can be stored for a long time, can be recycled, and is suitable for temporary surrounding support in various situations.

[0035] In one embodiment, as shown in Figure 2 In order to facilitate disassembly and assembly, recycling and reuse after use, the top and hypotenuse of the triangular frame 11 of the application are provided with connecting column ears 13, and the connecting column 22 is inserted or sleeved on the connecting column ears 13. In this way, the protective fence 2 can be disassembled and stored when not in use. It can be installed and used conveniently and recycled.

[0036] In one embodiment, as shown in Figure 2 In order to facilitate the installation and disassembly of the non-slip steel plate 3, the bottom side of the triangular frame 11 is provided with the stand 12 to support the non-slip steel plate 3, and the inner side of the hypotenuse of the triangular frame 11 is provided with the positioning ear 15 to facilitate the positioning and placement of the non-slip steel plate 3. The non-slip steel plate 3 is connected and arranged on the positioning ear 15 and the stand 12.

[0037] In the application, in order to facilitate the placement and disassembly of the non-slip steel plate 3, and also facilitate the disassembly of the two side supports 1 for storage, the non-slip steel plate 3 is arranged according to specific needs, as shown in Figure 4As shown, it is a top steel plate 31 arranged at the top of the side support 1, and the top steel plate 31 is provided with through holes at four corners, and the top steel plate 31 is sleeved on the top connecting lug 13 of the tripod 11. In this way, the anti-skid pattern steel plate 3 is arranged, and the two side supports 1 are also positioned and connected through the anti-skid pattern steel plate 3, which is convenient for disassembly and recovery.

[0038] In the present application, other anti-skid pattern steel plates 3 are not installed like the top steel plate 31, and thus the other anti-skid pattern steel plates 3 are also arranged according to specific installation, such as Figure 5 As shown, the second steel plate 32 is provided with notches at two corners, and the notches of the second steel plate 32 are clamped below the inclined edge of the side support 1 on one side of the positioning lug 15, and one side of the second steel plate 32 is connected to the stand column 12. The stand column 12 is provided with a positioning clamp 14 for clamping the second steel plate 32 as shown. Figure 3 When installed, the notched side is clamped below the inclined edge of the side support 1, limiting the left and right movement and rear movement of the second steel plate 32, and then the other side is clamped on the positioning clamp 14 of the stand column 12 to limit the forward movement on the step. In this way, the positioning and placement movement is completed, and the installation is stable and convenient for disassembly and recovery.

[0039] Finally, it should be noted that in this document, relationships such as first and second, and the like, are merely used to distinguish one entity or action from another, and do not require or imply that these entities or actions are in any way mutually exclusive or mutually related. In addition, the term includes, includes or any other variant is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
