Description

Technical Field

[0001] This application relates to the field of building materials technology, and more specifically, to a prefabricated insulated wall panel. Background Technology

[0002] With the development of the construction industry, the requirements for building energy conservation and environmental protection are becoming increasingly stringent. Precast insulated wall panels, as a new type of building material, have been widely used in the construction field due to their excellent thermal insulation performance and convenient construction. However, existing precast insulated wall panels still have some shortcomings in terms of structural design, thermal insulation performance, and connection methods. For example, the bonding between the insulation layer and the main wall panel is not firm, leading to a decrease in insulation effect; the connection between wall panels is not stable enough, affecting the overall integrity of the building structure; and some wall panels have poor fire resistance, posing safety hazards. Therefore, this paper proposes a precast insulated wall panel with a firm connection and good fire resistance. Utility Model Content
