Abstract

In response to the demand for improving tensile strength and construction quality in the construction of prefabricated steel structure wall panel connection nodes, this study optimizes the construction technology of connection nodes based on actual engineering projects and proposes a phased construction process. The process flow is to carry out dust removal, chip removal and other impurity cleaning on the surface of the wall panel during construction based on the specific conditions of the project, and complete on-site measurement and layout as well as board configuration; Then, based on the consideration of wind load parameters, design the node connection scheme between the exterior wall panel and the main structure (columns, floors), and develop targeted construction technology processes; Finally, the effectiveness of the proposed technology was verified through experiments. Research has shown that this technical system performs well in practical applications, not only ensuring that the construction quality of nodes meets acceptance standards, but also significantly improving the tensile performance of connecting nodes, effectively controlling residual deformation of wall panels, and providing a reference technical solution for similar projects.
