AI Technical Summary
In the existing technology, the welding process of vertical shaft steel bar grid requires multiple people to work together. The positioning of the main reinforcement bars and the calibration of the stirrups need to be adjusted repeatedly, resulting in poor frame stability and easy displacement during the welding process.
The rigid frame is constructed by cutting and shaping the bottom steel plate, top plate, and irregular steel plate as a whole. Combined with the double support components, it forms a triangular reinforcement system. The irregular steel plate has a built-in symmetrical placement groove design to accurately position the main steel bars. The modular pre-assembly design allows a single person to complete the positioning and welding independently.
It improves the stability and positioning accuracy of the steel frame, reduces the need for manual coordination, simplifies the operation process, and reduces the risk of welding misalignment.

[0002] Subway construction often involves pipeline relocation, and pipe jacking is particularly important in pipeline relocation. Pipe jacking involves the fabrication of steel gratings in vertical shaft construction. Therefore, the fabrication of steel gratings that meet design requirements and is carried out quickly is an important part of improving the quality of engineering construction.
[0003] Existing steel grating welding technology employs a step-by-step assembly method: first, the four main reinforcing bars are inserted one by one into the corresponding number of stirrup holes to form a preliminary frame structure; then, the intersections of some stirrups and main reinforcing bars are fixed by manual spot welding, ultimately completing the welding of the overall frame. This process has significant drawbacks: the operation requires multiple workers to work together, and the positioning of the main reinforcing bars and the alignment of the stirrups need repeated adjustments, resulting in poor overall frame stability; during the welding process, the components are prone to displacement due to being suspended in the air, requiring multiple stops for correction, making the assembly of individual steel grating pieces time-consuming and labor-intensive.
