Description

Technical Field

[0001] The invention belongs to the technical field of building energy conservation, relates to a thermal insulation board, and particularly relates to a hanging thermal insulation board for building exterior walls. Background Art

[0002] In the field of building energy conservation, exterior wall insulation technology is a key means of improving building energy efficiency, reducing energy consumption, and alleviating environmental impact. Despite significant progress in exterior wall insulation technology, existing solutions still face challenges, such as complex construction processes, low efficiency, and insufficient durability of insulation systems. Currently, exterior wall insulation primarily consists of three types: internal wall insulation, external wall insulation, and sandwich insulation. However, many older buildings in my country lack exterior wall insulation, severely impacting residents' quality of life and resulting in significant energy waste. Therefore, it is recommended that insulation panels be installed on the exterior surface of exterior walls. External insulation systems installed on the exterior of building walls not only avoid occupying indoor space but also effectively protect the walls from the adverse effects of temperature fluctuations and rainwater erosion. For example, in areas with significant temperature fluctuations, external insulation can mitigate the thermal expansion and contraction effects of temperature fluctuations, significantly reducing cracks in the walls and thus extending their service life. Furthermore, external insulation effectively prevents rainwater from directly eroding the walls, protects the interior of the walls from moisture, and prevents corrosion and expansion of the wall structure caused by prolonged moisture. In contrast, since the insulation layer of internally insulated buildings is located inside the wall, it cannot effectively prevent the erosion of the wall by external rainwater. The inside of the wall is more susceptible to moisture, which in turn affects the durability of the building structure.

[0003] The Chinese patent with publication number CN211899011U discloses a new type of magnetic insulation board, which includes an insulation board main body and a protective frame arranged on the periphery of the insulation board. The interior of the protective frame includes ferrite magnetic material, wire mesh polystyrene board, anti-cracking mortar, alkali-resistant mesh cloth, insulation layer, and waterproof layer from left to right. The wire mesh polystyrene board and the anti-cracking mortar are bonded together, the alkali-resistant mesh cloth is arranged between the anti-cracking mortar and the insulation layer, the insulation layer and the waterproof layer are bonded together, and a finishing layer is provided on the right side of the protective frame. Although the insulation board of this structure uses ferrite magnetic material to make the connection between different board layers tighter and less prone to warping, its installation method is still relatively complicated, and during long-term use, due to the lack of an effective connection structure, the insulation board may still fall off. Summary of the Invention
