Description

Technical Field

[0001] The present application relates to the technical field of building exterior wall insulation, and in particular to a passive building exterior wall insulation system. Background Art

[0002] Passive building exterior wall insulation is a building energy-saving technology designed to reduce energy consumption and improve indoor comfort by improving the thermal insulation performance of building exterior walls. This system typically involves laying insulation panels on the walls to enhance the building's thermal insulation. Existing insulation panels are typically installed by drilling holes in the wall, inserting rebar, and then laying the insulation panels, or by drilling holes through the insulation panels and then securing them with bolts.

[0003] The patent document with the published announcement number CN112012476B provides a prefabricated structure of a green building insulation wall. This published patent document fixes the fixing bracket and the template frame through a fixing bolt. When the fixing bolt is twisted, the threaded sleeve is threadedly connected to the threaded head. After continuing to twist the fixing bolt, the slider is pushed into the base wall around the end of the threaded sleeve, thereby squeezing the connecting rod, so that the protrusions between the connecting rods are rotated, preventing the screws from loosening due to external vibrations, making the template frame not easy to fall off; however, the insulation board used in the above-mentioned published patent document is fixed to the wall by screws, but each insulation board lacks connection and connectivity, and the falling force cannot be evenly dispersed. Therefore, it is easy to fall off after use. Utility Model Content
