[0040] One reinforcing layer 2 and the foamed ceramic layer 1 are attached, and the other reinforcing layer 2 and the ALC layer 3 are attached.

[0041] Specifically, foamed ceramic layer 1 adopts high-porosity closed-cell ceramic material formed by high-temperature firing, which has low thermal conductivity and can effectively prevent heat transfer, improving the thermal insulation performance of the wall.

[0042] The reinforcing layer 2 is generally composed of high-strength fiber material, metal mesh or other reinforcing material, and is respectively attached to the foamed ceramic layer 1 and the ALC layer 3, so as to increase the rigidity of the wall structure, improve the load-bearing capacity of the wall structure, and improve the ductility of the wall structure, avoid brittle failure of the wall structure under stress, and improve the safety and reliability of the wall structure.

[0043] Preferably, the reinforcing layer 2 is a reinforced mortar.

[0044] The reinforced mortar contains a large amount of cement and fine aggregate, which can significantly improve the compressive strength and shear strength of the wall structure, and enhance the overall rigidity of the wall. In addition, the reinforced mortar has good impermeability and corrosion resistance, which can effectively prevent the penetration of water and harmful substances and prolong the service life of the wall.

[0045] The reinforced mortar also has strong adhesion, and the adhesion between the reinforced mortar and the foamed ceramic wallboard and the ALC wallboard is strong, which ensures the close combination of each layer of material and improves the overall stability and reliability.

[0046] Preferably, the reinforcing layer 2 is a ductile mortar.

[0047] The ductile mortar contains fibers or other reinforcing materials, which can significantly improve the ductility and toughness of the mortar, allowing it to better absorb energy under stress and reduce the risk of brittle failure. In addition, the high ductility of the ductile mortar allows it to exhibit better seismic performance under dynamic loads such as earthquakes, effectively absorbing and dispersing seismic energy and reducing damage to the wall.

[0048] The ALC layer 3, i.e., the autoclaved lightweight concrete layer, can withstand large bending stress and enhance the overall structural strength of the wall. It also has the characteristics of lightweight and high strength, making it easy to transport and install, and reducing the self-weight of the building.

[0049] The insulation layer 4 includes polystyrene foam, rock wool, polyurethane foam, glass wool, etc. The thermal conductivity of the insulation layer 4 is negatively correlated with the thickness of the insulation layer 4.

[0050] The prefabricated foamed ceramic composite ALC sandwich insulation wall provided in the embodiment includes a plurality of insulation wall structures. The foamed ceramic wall layer has low thermal conductivity and good thermal insulation performance, effectively blocking heat transfer caused by internal and external temperature differences, thereby reducing the occurrence of thermal bridge effect. The combination of the foamed ceramic wall layer and the ALC layer 3 provides support for the wall structure while effectively insulating, ensuring the overall stability and durability of the wall.

[0051] A sandwich - thermal insulation layer 4 is arranged between the foamed ceramic wall layer and the ALC layer 3, and its thickness can be adjusted according to actual requirements to meet different thermal insulation requirements, further reducing the heat bridge phenomenon.

[0052] The utility model discloses a composite foamed ceramic wall layer and ALC layer 3 and sets up the thermal insulation layer 4 between the both, makes the thermal insulation wall structure not only can keep the efficient thermal insulation performance, and avoids the space occupation problem caused by internal thermal insulation.

[0055] A plurality of first reinforcing steel bars 5 are arranged in parallel in the first direction, which can strengthen the strength of the wall structure. When the wall structure is subjected to external load (such as wind load, earthquake load, etc.), the load will generate bending stress in the wall, and the first reinforcing steel bar 5 is located in the foamed ceramic layer 1 and close to one side of the reinforcing layer 2, which can effectively disperse the concentrated stress and prevent stress concentration in a certain point, thereby reducing the local deformation of the wall.

[0056] The first reinforcing steel bar 5 with a diameter greater than 6mm has higher tensile strength, can bear greater load, and has better corrosion resistance, which can improve the durability of the wall and prolong the service life of the wall.

[0057] In an embodiment, the first reinforcing steel bar 5 and the foamed ceramic layer 1 are integrated, and when the thermal insulation wall structure is manufactured, the first reinforcing steel bar 5 is placed with the length direction parallel to the first direction, and then the foamed ceramic slurry is covered on the first reinforcing steel bar 5, and after the foamed ceramic slurry is fired and solidified, the first reinforcing steel bar 5 is embedded in the foamed ceramic layer 1.

[0059] Preferably, the two reinforcing layers 2 are connected by a connecting layer 6 and the thermal insulation layer 4 respectively.

[0060] By arranging the connecting layer 6 on both sides of the thermal insulation layer 4 and connecting the two reinforcing layers 2 with the thermal insulation layer 4 through the connecting layer 6, the overall performance of the wall can be significantly improved.

[0061] Preferably, one of the reinforcing layers 2 and one of the connecting layers 6 are integrally arranged.

[0062] Preferably, the reinforcement layer 2 and the connection layer 6 are provided independently.

This significantly improves the overall stiffness and load-bearing capacity of the wall. Furthermore, the use of the connecting layers 6 not only enhances the connection strength between the layers but also ensures the integrity and stability of the composite insulation wall structure, preventing the layers from separating or falling apart when subjected to external forces.

Meanwhile, the number of the first reinforcing steel bars 5 also needs to take the weight of the thermal insulation wall structure into consideration.

[0066] Preferably, the number of the first reinforcing steel bars 5 is 2.

[0067] In one embodiment, the thermal insulation wall structure includes: at least one layer of steel mesh, and the steel mesh is embedded in the ALC layer 3.

[0076] Preferably, the diameter of the second reinforcing steel bars 7 is greater than 6 mm.

[0077] The third reinforcing steel bars and the second reinforcing steel bars 7 form a multi-layer reinforcing structure, which significantly improves the bending strength of the wall body. The reinforcing mesh can uniformly distribute stress, prevent local stress concentration, and provide additional support at key positions, thereby improving the bending performance of the wall body. At the same time, the reinforcing mesh improves the ductility of the wall body, so that the wall body can better absorb and disperse energy when subjected to dynamic loads such as earthquakes, thereby reducing the risk of damage.
