[0002] Building insulation refers to a method that starts from the building's surrounding enclosure structure and reduces the heat loss inside the building. It is of great significance for creating a good indoor thermal environment and energy saving. The commonly used method is to use a passive anchor assembly to combine the insulation material with the building's exterior wall. The current passive anchor assembly consists of a screw and an expansion tube. When the screw is tightened, the expansion strip of the expansion tube will expand outward, thereby exerting pressure on the anchor, thereby fixing the anchor in the fixing hole.
