[0001] This utility model relates to the field of passive and prefabricated energy-saving building technology, specifically a slotted threaded point assembly connector for buildings with built-in insulation panels. Background Technology
[0002] In passive building design, the external wall insulation system is a key component of the building envelope, and its thermal performance directly affects the overall energy consumption level and indoor thermal comfort of the building. Currently, mainstream external wall insulation structures generally use graphite polystyrene boards as the insulation layer, with structural connections achieved through a steel wire mesh system, resulting in a relatively large insulation thickness.

The steel wire mesh frame is not firmly locked, and cumulative displacement deviation is easy to occur during concrete pouring, resulting in the destruction of the continuity of the insulation layer and the formation of thermal bridge effect.
