It can be understood that the first horizontal direction, the second horizontal direction and the vertical direction mentioned in the text refer to the first horizontal direction, the second horizontal direction and the vertical direction in FIG. 1, the first horizontal direction, the second horizontal direction and the vertical direction are perpendicular to each other, and the first horizontal direction and the second horizontal direction are located on the same horizontal plane.

[0036] The structure of the climbing ladder in the embodiment is provided with a first threaded hole at a position corresponding to the hook portion 21 on the upper end side wall of the climbing ladder body in the vertical direction, and a first locking bolt 31 is screwed in the first threaded hole. During the use of the structure of the climbing ladder in the embodiment assembled on the steel column 1, the hook portion 21 is first hung on the top of the steel column 1, and then the first locking bolt 31 is driven to rotate forward in the first threaded hole, so that the first locking bolt 31 moves along the first horizontal direction to approach the steel column 1, so that the first locking bolt 31 is switched to the locked state, so that the climbing ladder body is stably connected to the steel column 1 under the friction between the outer side wall of the steel column 1 and the first locking bolt 31 and the friction between the inner side wall of the steel column 1 and the hook portion 21, thereby realizing the firm installation of the structure of the climbing ladder in the embodiment on the steel column 1 without damaging the steel column 1, ensuring the safety of the climbers, and meeting the safety and reliability requirements of the climbing operation of the climbers. When it is necessary to disassemble the structure of the climbing ladder in the embodiment from the steel column 1, the first locking bolt 31 is only driven to rotate reversely in the first threaded hole, so that the first locking bolt 31 moves along the first horizontal direction away from the steel column 1, so that the first locking bolt 31 is switched to the unlocked state, and the structure of the climbing ladder in the embodiment can be disassembled from the steel column 1 as a whole.

More specifically, the cross-sectional area of the anti-skid portion 311 perpendicular to the first horizontal direction is greater than the cross-sectional area of the rod portion of the first locking bolt 31 perpendicular to the first horizontal direction.

[0039] As shown in FIGS. 1 and 3, in some embodiments of the present application, the climbing ladder body includes at least two climbing members 41 which are sequentially detachably connected in the vertical direction. The corresponding number of climbing members 41 can be flexibly selected according to the actual height dimension of the steel column 1 in the vertical direction to adapt to the climbing ladder body with a corresponding height dimension, meet different climbing height use requirements, and have stronger applicability. It should be noted that the height dimensions of the climbing members 41 located at different vertical positions can be the same or different, meeting more climbing height use requirements.

Second, by arranging the connecting portions 2 on the climbing ladder body in the second horizontal direction, the distance between the two connecting portions 2 in the second horizontal direction can be flexibly adjusted according to the actual size of the steel column 1 in the second horizontal direction, so that the climbing ladder structure of the embodiment can be installed on the steel column 1 with different sizes in the second horizontal direction, and the applicability is stronger.

[0041] In order to facilitate the arrangement of the first threaded holes on the connecting portions 2, as shown in FIGS. 2 and 4, specifically, a first through hole 23 is formed on the connecting portion 2 in the first horizontal direction, a first nut 35 is fixedly connected to the connecting portion 2 at a position corresponding to the first through hole 23, and a threaded hole in the first nut 35 is arranged as the first threaded hole.

[0042] As shown in FIGS. 1 and 3, in some embodiments of the present application, the climbing member 41 includes two side plates 411 arranged in the second horizontal direction at intervals, a plurality of ladder step cross bars 412 are arranged between the two side plates 411, and the plurality of ladder step cross bars 412 are arranged at equal intervals in the vertical direction. The equally spaced ladder step cross bars 412 provide uniform foot space for the construction personnel, thereby facilitating the construction personnel to climb up and down along the climbing ladder structure of the embodiment, and achieving convenient construction on different height work surfaces.

[0043] As shown in FIG. 2 and FIG. 4, in some embodiments of the present application, a first through hole 22 is formed through the connecting part 2 along the second horizontal direction, which is adapted for the uppermost ladder step cross rod 412 to move through along the second horizontal direction; a second threaded hole is formed through the outer side wall of the connecting part 2, which is in communication with the first through hole 22; the second locking assembly comprises a second locking bolt 32 matched with the second threaded hole; when it is needed to adjust the movement of the connecting part 2 relative to the ladder along the second horizontal direction, the second locking bolt 32 is only needed to be reversely rotated in the second threaded hole, so that the second locking bolt 32 moves away from the ladder step cross rod 412, and the locking force between the connecting part 2 and the uppermost ladder step cross rod 412 is removed; when the connecting part 2 is locked after being adjusted to the required position, the second locking bolt 32 is only needed to be forwardly rotated in the second threaded hole, so that the second locking bolt 32 moves close to the ladder step cross rod 412 to abut against and tightly abut against the outer side wall of the uppermost ladder step cross rod 412, so that the locking and fixing are realized, and the whole adjustment process is convenient to operate.

[0044] In order to facilitate the arrangement of the second threaded hole in the connecting part 2, as shown in FIG. 4, specifically, a second through hole 24 is formed through the connecting part 2, which is in communication with the first through hole 22, and a second nut 36 is fixedly connected to the position of the outer side wall of the connecting part 2 corresponding to the second through hole 24, and the threaded hole in the second nut 36 is arranged as the second threaded hole.

The reinforcing part 42 with the first hook arm 421 and the second hook arm 422 provides another connecting line between the two adjacent ladder parts 41, which ensures that even if the detachable connection between the two adjacent ladder parts 41 is loose, the two ladder parts 41 will not be separated from each other due to the gravity generated by the climbing of the construction personnel, and the safety of the construction personnel climbing the ladder is ensured.

[0046] As shown in FIG. 1 and FIG. 2, in some embodiments of the present application, the climbing member 41 further comprises two support members 413, which are respectively arranged on one side of the side plates 411 along the first horizontal direction; the support members 413 are adapted to abut against the outer side wall of the steel column 1 on the side away from the side plates 411 along the first horizontal direction. The side plates 411 and the ladder step cross bars 412 are spaced apart from the outer side wall of the steel column 1 along the first horizontal direction by the support members 413, so that the construction personnel can step on the ladder step cross bars 412 to climb up and down. Specifically, the support members 413 are connected with the steel column 1 by a hoop, which connects the climbing ladder body with the steel column 1 more firmly and effectively prevents the climbing ladder body from sliding or losing stability.

[0047] As shown in FIG. 5 and FIG. 6, in some embodiments of the present application, the lower end of the side plates 411 along the vertical direction overlaps with the projection of the upper end of the vertically adjacent side plates 411 along the vertical direction along the second horizontal direction; the overlapping portions of the adjacent two side plates 411 are detachably connected by a third locking assembly. The lower end of the side plates 411 of the upper climbing member 41 overlaps with the upper end of the side plates 411 of the adjacent and lower climbing member 41, and they are integrally connected by the third locking assembly, which makes the connection more firm.
