Description

Technical Field

[0001] This utility model relates to external wall insulation systems, and more particularly to a modular repair structure and the repaired external wall insulation system. Background Technology

[0002] External wall insulation system is a type of insulation system fixed to the exterior walls of a building, which has the advantages of heat preservation, heat insulation, energy saving and protection of the exterior walls.

[0003] After long-term use, the external wall insulation system is prone to quality defects. Generally, it is necessary to connect the insulation layer and the finishing layer on site for repair. Moreover, the next layer can only be connected after the previous layer has reached a certain strength, which can easily lead to low repair efficiency. Utility Model Content

[0018] Specifically, during the repair process, firstly, infrared thermal imaging combined with manual tapping is used to identify and mark the defective area 8.
