Research on the Control Method of Installation Deviation of Prefabricated Exterior Wall Panels

The size deviation of the prefabricated external wall panel is affected by various factors, which causes the wall panel to be reworked during on-site installation. In order to achieve the smooth installation and small local cumulative deviation of prefabricated external wall panels with splicing requirements, the method of optimizing the installation sequence of wall panels based on the secondary development of Revit is an effective way to solve the above problems. After explaining the working principle of the method in detail, an example was used to verify the effectiveness of the method, and the results of the algorithm operation were compared with the results of hand calculations. The results show that the method can generate the best assembly plan effectively, which is beneficial to reduce the difficulty of assembling prefabricated external wall panels.
