For example, the use of prefabricated building panels as building wall materials is becoming more and more widespread. The traditional polyurethane thermal insulation construction method usually adopts the spraying construction method after the steel structure house frame and exterior wall panels are built and installed, and then the interior wall panels are installed after the polyurethane rigid structure to form prefabricated building panels. In order to save installation time and improve installation efficiency, the industry has developed the direct use of prefabricated environmentally friendly building panels as walls, such as environmentally friendly building panels prefabricated from the outside to the inside using aluminum alloy panels, polyurethane layers, and insulation layers. This type of panel has thermal insulation and high self-strength, which conforms to the concept of prefabricated green buildings. Usually, a wall requires a combination of multiple environmentally friendly building panels to cover the entire area. The environmentally friendly building panels at the outermost end of the wall and the environmentally friendly building panels on the ground need to be fixed to another wall or the ground. Especially for long walls, special connectors are required to ensure the overall stability and aesthetics during the installation and laying process.
