The spacing node C between the steel upright post and the supporting upright post 211 of the steel structure 10 is the bidirectional spacing of the T-shaped spacing groove 122 of the spacing plate 121 to the spacing track 231 on the supporting upright post 211, namely, the bidirectional spacing in the X-axis direction and the Y-axis direction is realized, the structural stability of the supporting upright post 211 is further enhanced, and the supporting upright post 211 can be firmly and stably attached to the steel upright post of the steel structure 10. The Y-axis direction is the setting direction of the sliding rail 31, the X-axis direction is the direction perpendicular to the sliding rail 31, and the Z-axis direction is the vertical direction, that is, the climbing direction of the supporting upright post 211. The articulated joint D at the bottom of the hydraulic lifting mechanism 22 is a spherical base omni-directional articulation.
As shown in fig. 2, preferably, the design height of the climbing frame structure 21 in the climbing system of the invention can be determined according to the design characteristics of the steel structure in actual construction, the height of the supporting upright post 211 can be selected and adapted according to the construction characteristics of members in the steel structure, for example, the height of the supporting upright post 211 can be designed to be seven-layer building height for construction of four layers of running water, the supporting upright post 211 at the bottom two-layer height is used as a support and is connected with the steel upright post of the steel structure through a limit track and a limit piece, the middle four layers are used as steel structure installation layers, namely the construction layer, the top layer is the operation space layer of the truss crane system, the supporting upright post 211 of the climbing frame structure 21 in the invention is connected with the steel upright post of the steel structure through a hydraulic jacking mechanism and a limit track, and inclined supporting rods are arranged between the supporting upright posts to be tied and fixed, so that the stability and reliability of the climbing system can be ensured.
The present invention has been described in detail with reference to the embodiments of the drawings, and those skilled in the art can make various modifications to the invention based on the above description. Accordingly, certain details of the illustrated embodiments are not to be taken as limiting the invention, which is defined by the appended claims.
