Most of the existing temporary bracket structures are constructed by embedding steel plates in pier (tower) columns and then welding the steel plates. The bracket structure has great welding work amount and more overhead operations. However, due to manual operation, the influence of human factors is large, and the overall quality of field construction cannot meet the structural requirements easily. The temporary engineering, particularly the temporary engineering required by large-scale structures such as 0# blocks and the like, has higher construction requirements. In actual construction, operation workers often have unsatisfactory welding, field processing and blanking accuracy. The construction quality of the temporary structure is difficult to ensure the construction safety, and a large number of temporary structures need to be processed on site, and high-altitude and suspended operation and the like are more, so that the safety risk is very high in construction.
