[0002] In the field of building reinforcement engineering, there are many reinforcement methods, the most common ones are pasting carbon fiber cloth, increasing the cross-section method, external steel method, replacement concrete method, etc. Before reinforcing the vertical components, it is often necessary to effectively support them to ensure that the load transfer path of the original structure is unobstructed and prevent the original structure from being affected during the construction project. In the support system, there are various forms of vertical support, which plays a key role in transferring the vertical load of the reinforced components to the next layer. In the actual construction process, the vertical support is often directly installed on the horizontal support or located on the original structural member. Due to the processing error of the vertical support end face, the horizontal error of the horizontal support installation and the unequal force surface of the original structure, and considering the manual installation deviation, the vertical support center and the horizontal support are often not completely aligned.
