Description

Technical Field

[0002] In the field of modern construction, energy conservation and environmental protection have become important factors that cannot be ignored. Although traditional wall materials, such as brick walls and concrete walls, have excellent structural strength, they are obviously insufficient in thermal insulation performance. In recent years, with the development of material science and the popularization of environmental protection concepts, prefabricated sandwich insulation wall panels have gradually attracted people's attention as a new type of building material. This wall panel adopts a structure in which the insulation layer is sandwiched between two layers of concrete wall panels inside and outside. It not only has excellent thermal insulation performance, but also can effectively isolate noise and moisture penetration. At the same time, prefabricated sandwich insulation wall panels are prefabricated in the factory, which can greatly reduce construction waste and noise pollution at the construction site, meeting the requirements of modern buildings for environmental protection and energy conservation.

[0003] However, there are still some problems in the design and manufacturing process of existing prefabricated sandwich insulation wall panels. For example, the connection between the insulation layer and the inner and outer wall panels is not tight enough, which easily leads to reduced insulation effect and water seepage; the structural strength of the inner and outer wall panels is not high enough to meet the needs of high-rise buildings; the connection and installation between wall panels are not convenient, which increases the difficulty and cost of construction.

[0004] Therefore, developing a prefabricated sandwich insulation wall panel with reasonable structure, excellent thermal insulation performance and convenient installation is of great significance for improving the thermal insulation performance of buildings, reducing energy consumption and reducing environmental pollution.
