Description

Technical Field

[0001] The utility model relates to a composite wall structure. Background Art

[0002] Composite wall is a composite building structure that has been widely used in modern buildings. It not only provides excellent thermal insulation, but also has multiple functions such as fireproofing, waterproofing and sound insulation. Composite insulation wall is composed of several different materials. The inner layer is reinforced concrete wall or masonry structure wall, the middle layer is insulation material, and the outer layer is decorative material. This multi-layer structure wall has excellent thermal insulation performance, can effectively isolate the temperature difference between indoor and outdoor, prevent heat transfer, maintain indoor temperature stability, and improve energy efficiency. It also has high strength. The composite insulation wall uses concrete or masonry as the inner layer structure, which has high seismic resistance and bearing capacity.

[0003] The sudden drop in temperature in winter causes the exterior walls of buildings to shrink. During this shrinkage, the structural layer of the exterior walls of buildings will tear during this shrinkage process, which is manifested as the insulation layer sticking point detaching. Under greater wind pressure, the exterior walls of buildings vibrate and lose adhesion, which in turn causes the structural layer to be damaged or hollowed out. At the same time, due to the poor ability of the insulation layer of the exterior walls of buildings to bear vertical loads, after years of use, the structural layer of the exterior walls of buildings will be damaged under vertical loads, which will also cause hollowing and falling off, reducing the service life of the structural layer of the exterior walls of buildings. The existing structural layer of the exterior walls of buildings has poor ability to resist hollowing and falling off. For example, the exterior wall insulation structure of buildings disclosed in patent CN103669621A is composed of an adhesive layer, a thermal insulation layer and a protective layer. The adhesive layer is bonded to the outside of the exterior wall of the building, the thermal insulation layer is located outside the adhesive layer, and the protective layer with an anti-corrosion effect is located outside the thermal insulation layer; wherein the thermal insulation layer is a foam board made of foam material; and the specific material of the protective layer is anti-cracking mortar. Similar to the exterior wall system in patent CN103669621A, it lacks a transverse reinforcement structure and neglects the prevention of hollowing and falling problems, so the safety is poor.
