Turnover type steel supporting joint installation method

The invention discloses a turnover type steel supporting node installation method, and particularly relates to the technical field of supporting node installation, and the method comprises the following specific steps: S1, prefabricated member processing, S2, prefabricated member size verification, S3, prefabricated member repair verification, S4, supporting node installation, S5, supporting node graph scanning comparison, S6, supporting node stress verification, and S7, supporting node image verification. According to the method, the length, width and height of each structure of the prefabricated part are measured through a measuring instrument, the problem that a component needing to be repaired is scratched on the prefabricated part is marked, the scratches are evenly smeared with a filling agent, it is ensured that the whole groove is filled with the filling agent, and when the turnover type steel supporting node is installed, detection fulcrums are constructed in real time; after the turnover type steel
