[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0023] The embodiments of this application provide a new type of ALC composite wallboard, which can solve the problem in the related art that the current ALC wallboard is a large integral wallboard and requires the use of a large autoclave for operation during production and manufacturing, resulting in high production costs.

[0024] See Figure 1 and Figure 2 As shown, the embodiments of this application provide a new type of ALC composite wallboard, including a wallboard body. The wallboard body includes a multi-chambered enclosure 2, and a plurality of ALC core blocks 1 are embedded in the multi-chambered enclosure 2 at intervals. In actual use, since the ALC composite wallboard of this application includes a wallboard body, and the wallboard body includes a multi-chambered enclosure 2 and a plurality of ALC core blocks 1 embedded in the multi-chambered enclosure 2 at intervals. Since the ALC core blocks 1 are multiple small block-shaped ALC boards, it is possible to meet the ALC characteristics of the wallboard while not requiring the use of a large autoclave to produce the entire large ALC board at one time. Instead, a smaller autoclave of a suitable model can be used to manufacture the ALC core blocks 1, which can improve the production flexibility and reduce the production cost while ensuring that the wallboard has the characteristics of an ALC board.

[0025] In some alternative embodiments, the multi-chambered enclosure 2 is made of fine aggregate concrete. The multi-chambered enclosure 2 made of fine aggregate concrete can be well-connected and fixed with the ALC core blocks 1, and can ensure the structural strength without affecting the performance of the ALC core blocks 1.

[0026] In some alternative embodiments, the ALC core blocks 1 are triangular or hexagonal in structure. The setting of the ALC core blocks 1 being triangular or hexagonal in structure can facilitate docking, matching, and fixing with the cavities opened in the multi-chambered enclosure 2, ensuring the structural strength and stability.

[0027] As Figure 1 shown, in some alternative embodiments, the ALC core blocks 1 are arranged at equal distances at intervals in both the horizontal and vertical directions. Being arranged at equal distances at intervals in both the horizontal and vertical directions can ensure the regularity and balance of the arrangement of the ALC core blocks 1 in the multi-chambered enclosure 2 to ensure the structural strength and stability.

[0028] As Figure 2As shown, in some embodiments, a reinforcement protective layer is provided on the side wall of the wall panel body. The current ALC wall panel is made of autoclaved lightweight concrete, which has the inherent material characteristics of being porous and loose. Its absolute strength is relatively low, its impact resistance is poor, and its dry shrinkage property is poor, resulting in easy cracking and water seepage. By providing a reinforcement protective layer on the side wall of the wall panel body, the deficiencies of the ALC wall panel can be supplemented and strengthened.

[0029] Specifically, in some alternative embodiments, the reinforcement protective layer includes a cold-drawn low-carbon steel wire mesh 3 disposed on the side close to the side wall of the wall panel body, and a concrete composite panel 4 disposed on the outer wall of the cold-drawn low-carbon steel wire mesh 3. The cold-drawn low-carbon steel wire mesh 3 is disposed close to the wall panel body, which can enhance the absolute strength of the structure, while the concrete composite panel 4 is disposed on the outer wall of the cold-drawn low-carbon steel wire mesh 3, that is, it is disposed on the outermost layer, which can improve the impact resistance and crack and water seepage resistance of the composite wall panel. In some alternative embodiments, the concrete composite panel 4 is made of a mixture of glass fiber and fine aggregate concrete, with easy cost control and relatively high structural strength, capable of having strong impact resistance, and being crack-resistant and water-seepage-proof. The setting of the reinforcement protective layer can improve the overall strength and heat insulation and sound insulation performance of the wall panel, reduce cracking, and improve the water leakage resistance.

[0030] In some alternative embodiments, the cold-drawn low-carbon steel wire mesh 3 is made of Q235B steel, which has good strength and toughness.

[0031] In some embodiments, the thickness of the ALC core block 1 is 20 - 900 mm, and the thickness of the multi-chambered enclosure 2 is 50 - 300 mm. In some embodiments, the thickness of the concrete composite panel 4 is 50 - 300 mm. In actual use, the ALC core block 1, multi-chambered enclosure 2, and concrete composite panel 4 with appropriate thicknesses can be selected according to specific circumstances for use.

[0032] In summary, the novel ALC composite wall panel of the present application includes a wall panel body, and the wall panel body includes a multi-chambered enclosure 2, and a plurality of spaced ALC core blocks 1 are embedded in the multi-chambered enclosure 2. In actual use, since the ALC composite wall panel of this application includes a wall panel body, which includes a multi-chambered enclosure 2 and a plurality of spaced ALC core blocks 1 embedded in the multi-chambered enclosure 2, and since the ALC core blocks 1 are multiple small block-shaped ALC boards, it is possible to satisfy the ALC characteristics of the wall panel without using a large autoclave to produce the entire large ALC board at one time. Instead, a relatively small autoclave of a suitable model can be used to manufacture the ALC core blocks 1, which can improve the production flexibility and reduce the production cost while ensuring that the wall panel has the characteristics of an ALC board.

[0033] Reinforcing protective layers are provided on the side walls of the wall panel body. At present, due to its material being autoclaved lightweight concrete, the existing ALC wall panels have the inherent material characteristics of being porous and loose, with relatively low absolute strength, poor impact resistance, and poor dry shrinkage resistance, resulting in easy cracking and water seepage. By providing reinforcing protective layers on the side walls of the wall panel body, the deficiencies of the ALC wall panels can be supplemented and strengthened. Specifically, the reinforcing protective layer includes a cold-drawn low-carbon steel wire mesh 3 disposed on the side closer to the side wall of the wall panel body, and a concrete composite panel 4 disposed on the outer wall of the cold-drawn low-carbon steel wire mesh 3. The cold-drawn low-carbon steel wire mesh 3 is disposed closer to the wall panel body, which can enhance the absolute strength of the structure, while the concrete composite panel 4 is disposed on the outer wall of the cold-drawn low-carbon steel wire mesh 3, that is, it is disposed on the outermost layer, which can improve the impact resistance and anti-cracking and water-seepage performance of the composite wall panel. In some alternative embodiments, the concrete composite panel 4 is made of a mixture of glass fiber and fine aggregate concrete, with easy cost control and relatively high structural strength, capable of having strong impact resistance, and being crack-resistant and water-seepage-proof.

[0034] This technical solution provides a new type of ALC composite wall panel. This new type of wall panel is light in weight, being 1 / 4 of ordinary concrete and 1 / 3 of clay bricks, and has relatively high strength. It has good heat insulation performance. The microstructure of the new type of wall panel consists of countless non-connected and uniform tiny air holes, giving it good heat insulation performance, which is about 10 times that of ordinary concrete and 7 times that of clay bricks, making it a building material with excellent heat insulation performance. It has good flame retardancy and fire resistance. The new type of wall panel uses non-combustible silicate materials, with a high thermal resistance coefficient and good thermal stability, having very high fire resistance and not generating harmful gases under high temperature and open fire. It has good sound absorption and sound insulation performance. The uniform and non-connected tiny air holes of the new type of wall panel have dual performance of sound insulation and sound absorption, which can create a more airtight and quieter indoor atmosphere. It has good anti-leakage and anti-freezing and cracking performance. Most of the air holes of the new type of wall panel are tiny closed holes, having good anti-leakage and anti-freezing and cracking performance, and better adaptability to environmental temperature and humidity. The production process is simple. The new type of wall panel has standard product dimensions and is light in weight. The production and installation processes of the wall panels are simple and efficient, which can effectively shorten the construction period. And the cost is relatively low.

[0035] The ALC composite wall panel of the present application has the following advantages: low production cost; simple process; guaranteed physical properties such as self-weight, flexural resistance, flexural strength, sound insulation, and anti-seepage. Through the innovative improvement of the wall panel performance, the use efficiency of precast components is ensured, and the construction convenience is improved. At the same time, it can save costs and reduce the pollution sources of project construction.

[0036] It has certain economic efficiency; since prefabricated components such as wall panels are completed in the factory, the on-site actual workload is correspondingly reduced, and the construction is less affected by seasonal and weather changes, which is beneficial to the improvement of construction efficiency and the control of construction costs.

[0037] It can ensure the project quality; the prefabricated new wall panels have strong quality advantages, solving the later maintenance problems caused by construction quality from the source. The prefabricated components are produced in a factory and standardized manner, which can avoid construction defects caused by human factors.

[0038] The environmental cost is controllable; due to the reduction of the amount of on-site pouring and a large amount of plastering work, the on-site wet operations are reduced, and correspondingly, a large amount of non-renewable construction waste, sewage and dust are reduced. At the same time, the noise pollution during construction is reduced.

[0039] Therefore, the development of green buildings, the use of green building materials, and the adoption of green construction methods are the general trend of future project construction. This solution conforms to the current situation, provides reliable technical support for the promotion of prefabricated buildings, has a broad market prospect, and is also a sustainable technical guarantee for building industrialization, with certain economic value and social value.
