[0034] Embodiment 1

[0035] The utility model embodiment provides a kind of prefabricated foamed ceramic composite ALC light wallboard 200, including several wall units 100, the wall unit 100 includes: foamed ceramic structure 1, ALC structure 2;

[0036] The foamed ceramic structure 1 is located at the outer layer of the wall unit 100, and the ALC structure 2 is located at the inner layer of the wall unit 100.

[0037] Specifically, the foamed ceramic structure 11 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 unit.

[0038] The ALC structure 23, i.e., the autoclaved lightweight concrete layer, can withstand large bending stress and enhance the overall structural strength of the wall, and has the characteristics of lightweight and high strength, facilitating transportation and installation, and reducing the self-weight of the building.

[0039] By arranging the foamed ceramic structure 1 on the outer layer of the wall unit 100, the foamed ceramic material has low thermal conductivity, good thermal insulation performance, and strong waterproof and moisture-proof properties, which can effectively prevent the transmission of external temperature and avoid moisture and water penetration, thereby maintaining the stability of the internal environment of the wall and realizing the thermal insulation, waterproof and moisture-proof properties of the wall unit 100.

[0040] The ALC (autoclaved lightweight concrete) material has high compressive strength and bending resistance, and is arranged on the inner layer of the wall unit 100 to ensure that the wall unit 100 has sufficient structural strength and meets the requirements of prefabricated buildings on the load-bearing capacity of the wall.

[0041] Meanwhile, by combining the foamed ceramic structure 1 with the ALC structure 2, the waterproof and moisture-proof performance of the foamed ceramic structure 1 effectively avoids the problems of moisture absorption and steel bar corrosion of the ALC structure 2, and improves the durability and service life of the wall body. The compression and bending resistance of the ALC structure 2 ensures the structural stability of the wall body in long-term use, and reduces the risk of stress deformation of the wall body.

[0042] Preferably, the wall body unit 100 further comprises an adhesive layer 3 arranged between the foamed ceramic structure 1 and the ALC structure 2.

[0043] The adhesive layer is one of foamed ceramic polymer adhesive mortar and ALC adhesive mortar, which ensures the structural stability and long-term use performance of the composite material.

[0044] The adhesive layer 3 can ensure the close combination of the foamed ceramic structure 1 and the ALC structure 2 after the combination, and prevent them from separating or cracking due to stress or temperature change in long-term use. The adhesive layer 3 can enhance the structural integrity between the foamed ceramic structure 1 and the ALC structure 2, and ensure that the physical performance of the entire wall body unit 100 is not damaged; at the same time, it can also avoid damaging the original performance of foamed ceramic and ALC due to strong connection, and the high-strength and flexible adhesive material helps to maintain the performance characteristics of the two materials, so that the wallboard can be moderately bent when bearing external force, preventing brittle fracture.

[0045] In an embodiment, the wall body unit 100 comprises a plurality of first reinforcing steel bars 4 arranged and installed on one side of the foamed ceramic structure 1 close to the adhesive layer 3.

[0046] By arranging and installing a plurality of first reinforcing steel bars 4 in parallel in the first direction, the strength of the wall body unit 100 is strengthened. When the wall body unit 100 is subjected to external loads (such as wind load, earthquake load, etc.), bending stress will be generated in the wall body unit 100, and the first reinforcing steel bars 4 located on the side of the foamed ceramic structure 1 close to the adhesive layer 3 can effectively disperse these concentrated stresses, preventing stress concentration at a certain point, thereby reducing the local deformation of the wall body.

[0047] The first reinforcing steel bars 4 with a diameter greater than 4 mm have higher tensile strength, can bear greater load, and have better corrosion resistance, which can improve the durability of the wall body and prolong the service life of the wall body.

[0048] In an embodiment, a plurality of installation grooves 11 are arranged on the side of the foamed ceramic structure 1 close to the adhesive layer 3 along the first direction, and the first reinforcing steel bars 4 are fixed in the installation grooves 11 by adhesion.

[0049] The first direction is the length direction of the wall unit 100, and the mounting groove 11 is linear or rectangular in the first direction. The mounting groove 11 provides an oriented mounting space, so that the first reinforcing steel bars 4 can be arranged and fixed along the first direction, ensuring the correct position and direction of the steel bars, avoiding the deviation or dislocation of the first reinforcing steel bars 4 during installation, and effectively sharing the load with the foamed ceramic structure 1 in the mounting groove 11 during the stress process of the wall, improving the tensile and bending resistance. The bonding and fixing technology makes the connection between the steel bars and the foamed ceramic structure 1 more firm, ensuring that the mechanical properties of the two are not damaged.

[0050] Preferably, the first reinforcing steel bars 4 are installed and fixed in the mounting groove 11 by epoxy resin, polyurethane glue or cement-based adhesive. Bonding and fixing can avoid the slip between the first reinforcing steel bars 4 and the foamed ceramic structure 1 due to temperature difference or long-term load, reduce the risk of structure damage, and prolong the service life of the wall.

[0051] Preferably, the width and depth of the mounting groove 11 are not less than the diameter length of the first reinforcing steel bars 4, which can ensure that the first reinforcing steel bars 4 are completely fixed and installed in the mounting groove 11, and can effectively share the load with the foamed ceramic structure 1, improving the tensile and bending resistance.

[0052] In another embodiment, the first reinforcing steel bars 4 and the foamed ceramic structure 1 are integrated structures. When manufacturing the wall unit 100, the length direction of the first reinforcing steel bars 4 is parallel to the first direction, and then the foamed ceramic slurry is covered on the first reinforcing steel bars 4. After the foamed ceramic slurry is fired and solidified, the first reinforcing steel bars 4 are embedded in the foamed ceramic structure 1. The number of first reinforcing steel bars 4 in the foamed ceramic structure corresponding to one wall unit 100 is not less than 2.

[0053] Preferably, two first reinforcing steel bars 4 are fixed and installed in the foamed ceramic structure 1 of one wall unit 100.

[0054] In an embodiment, the wall unit 100 comprises at least one layer of steel mesh 5, and the steel mesh 5 is embedded in the ALC structure 2.

[0055] The steel mesh 5 can significantly improve the tensile strength and overall stiffness of the ALC structure 2, preventing the ALC structure 2 from cracking or deforming when subjected to external load. The grid structure of the steel mesh 5 can uniformly distribute stress, improving the overall stability and load-bearing capacity of the wall.

[0056] Preferably, as shown in Figure 2 When the ALC structure 2 is embedded with a single layer of steel mesh 5, the steel mesh 5 is located at the center of the ALC structure 2.

[0057] Preferably, as shown in the drawings, when the ALC structure 2 is embedded with a double-layer steel mesh 5, the two layers of steel mesh 5 are arranged at a certain distance to ensure the overall structural strength and stress uniformity of the ALC structure 2. Figure 4

[0058] Preferably, the steel mesh 5 comprises a plurality of second reinforcing steel bars 51 and a plurality of third reinforcing steel bars 52.

[0062] The second reinforcing steel bars 51 and the third reinforcing steel bars 52 are arranged vertically to ensure uniform distribution of the steel bars in the wall body, improve the overall stability and uniformity of the wall body, further enhance the bending strength and load-bearing capacity of the ALC structure 2, and improve the overall performance of the wall body.

[0063] Preferably, the diameter of the second reinforcing steel bars 51 is greater than 4mm.

[0064] The arrangement of the third reinforcing steel bars 52 and the second reinforcing steel bars 51 in this embodiment forms a multi-layer reinforcing structure, which significantly improves the bending strength of the wall body unit 100. The steel mesh 5 can uniformly distribute stress, prevent local stress concentration, and provide additional support at key positions to improve the bending performance of the wall body. At the same time, the steel mesh 5 improves the ductility of the wall body, so that it can better absorb and disperse energy when subjected to dynamic loads such as earthquakes, reducing the risk of damage.
