[0002] Faced with the current increasingly rapid urbanization, people have also put forward new requirements for the quality of building structures. As a construction company, we must strengthen technological development and continuously improve the construction technology of building structures. In particular, we must focus on researching and developing the key construction technology points of exterior wall structures to improve the quality of construction projects.

[0003] The construction of the existing technology has the following shortcomings: 1) The existing keels used for the installation of aluminum alloy curtain walls are mostly cumbersome to position when installed with the aluminum alloy curtain walls, which is time-consuming and has low installation efficiency; 2) The installation structure of the building exterior wall steel plate in the existing technology is simple, and the exterior wall steel plates are mostly connected by direct welding or right-angle edges, which will expose the steel cross-section to the outside, and the internal substrate is easily corroded. At the same time, the joint surface between the steel plates has poor sealing, which is prone to leakage, poor practicality, and short service life; 3) The curtain wall lofting of three-dimensional coordinates has always been a major problem in construction. In the construction of heterogeneous curtain walls, in order to ensure the accuracy of the installation quality, it is often necessary to install the curtain wall keels while positioning and lofting, which slows the construction speed and causes serious idleness of the installers.
