Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a reinforced ALC wall panel structure and an assembled installation method. Background Art

[0002] ALC (Autoclaved Lightweight Concrete) wall is a prefabricated building material known for its light weight but high strength; ALC wall panels have the following characteristics: light weight, good thermal insulation, good sound insulation, high fire resistance, low moisture resistance, environmentally friendly production process and materials, ALC panels are commonly used for exterior walls, interior partitions, floors and roofs of various building types, including residential, commercial and industrial structures.

[0003] ALC wall panels are a type of building material in prefabricated buildings. Their greatest feature is that they are light and easy to install. ALC panels can be prefabricated into specific sizes and shapes, making them easy to install and reducing construction time. Although ALC (autoclaved lightweight concrete) wall panels have many advantages, they also have some disadvantages in strength and structure. The disadvantages in strength are:

[0004] (1) Low tensile strength: ALC wall panels have relatively low tensile strength, so they are prone to cracking when subjected to tensile stress.

[0005] (2) Brittleness: ALC wall panels are relatively brittle and easily cracked or shattered when impacted or collided.

[0006] (3) Limited local load-bearing capacity: Although ALC wall panels have high overall strength, their local load-bearing capacity is relatively limited and requires additional structural support in applications requiring high load-bearing capacity.

[0007] Structural disadvantages:

[0008] (1) Requires special connectors and construction technology: Due to the characteristics of ALC wall panels, specially designed connectors and construction methods are required during installation. This increases the complexity and cost of construction and requires skilled workers to ensure the quality of installation.

[0009] (2) Contraction and expansion: ALC wall panels will shrink and expand to a certain extent when the ambient humidity and temperature change. This change may cause cracks in the wall or instability in the joints. During construction, it is necessary to reserve expansion joints or use elastic sealing materials to reduce this effect.

[0010] (3) High requirements for surface treatment: The surface of ALC wall panels usually requires secondary treatment, such as plastering or coating, to improve aesthetics and waterproof performance. This increases construction time and cost.

[0011] How to further improve the convenience of installation of ALC wall panels and improve the strength of ALC wall panels so as to reduce the load on the building and maintain the stability of the frame of high-rise buildings without reducing the strength of the wall; thereby achieving the effect of reducing construction costs and enhancing building strength, is one of the methods that the current construction industry needs to explore in the direction of cost reduction, efficiency improvement and sustainable development.

[0012] In summary, it is found that the prior art has at least the following technical problems:

[0035] The reinforced ALC wall panel structure, through its unique structural design, realizes the internal support formed by the lightweight concrete filler and the steel skeleton being embedded in one body, and can have higher mechanical properties, which is greatly improved compared with the stress-bearing performance of existing ALC wall panels.

[0036] (1) Improved strength and stability: The reinforced ALC wall panels have a unique shape and a steel frame structure with very little steel, which greatly improves the strength and stability of the wall panels, while further strengthening the lightweight index. The central cage frame, as the core supporting structure, adopts a circular design, providing strong tensile and compressive resistance. The first vertical and transverse tension bars are arranged on the vertical and transverse radial sides of the central cage frame, respectively, and are perpendicular to each other. This design ensures the stability of the steel frame in all directions and transfers the force connecting the outer frame to the central cage frame at the center of the steel frame, making the force more uniform. The introduction of the second vertical tension bar further enhances the transverse shear resistance and vertical compressive resistance of the wall panels.

[0037] (2) Construction simplicity and efficiency: This design continues the fast and convenient construction of prefabricated buildings and simplifies the construction process of existing ALC wall panels through structural optimization. The steel skeleton is pre-welded and formed in the factory, and then installed and welded in the connecting frame; under the autoclaving and aeration treatment in the factory, the lightweight concrete filler is poured into the connecting frame and pressed into shape with the steel skeleton; this prefabricated wall panel method can ensure the high-precision installation of the steel skeleton and ensure uniform force, and also greatly shorten the on-site construction time and improve construction efficiency; the standardized steel skeleton and connecting frame design make the production and installation of wall panels more modular, which is convenient for large-scale promotion and application.

[0038] (3) Durability and earthquake resistance: This reinforced ALC wall panel design makes the wall panel have excellent durability and earthquake resistance. The steel skeleton provides reliable tensile and compressive support, and can evenly bear the force of the four sides of the wall panel connected to the outer frame, and distribute the force of each side to the center of the steel skeleton, ensuring that the wall panel is evenly stressed and not easy to deform during long-term use, and the lightweight concrete filler is also not easy to deform and crack. At the same time, the lightweight concrete filler is tightly fitted with the steel skeleton to form an integral internal support structure, which effectively disperses and absorbs external shocks and vibrations, and improves the earthquake resistance of the wall panel. This structure is particularly suitable for earthquake-prone areas and high-rise buildings. It can achieve a higher lightweight static load and provide reliable force support, which can significantly improve the safety of the building.

[0039] (4) Economic benefits: First, the prefabrication of the steel skeleton and the prefabrication of lightweight concrete reduce material waste and construction costs. Second, the modular production, transportation and installation methods improve construction efficiency, shorten the construction period and reduce labor costs. In addition, the high strength and durability of the reinforced ALC wall panels reduce maintenance and repair costs, extend the service life of the building, and further reduce long-term use or operation costs.

[0040] In summary, this reinforced ALC wall panel structure, through the combination of steel skeleton and lightweight concrete filler, provides excellent tensile, compressive and seismic performance, while having a simple installation process and significant economic benefits. It is suitable for various prefabricated buildings or high-rise buildings that require lightweight, especially buildings that require high strength and high stability.

[0059] (1) Improved strength and stability: The reinforced ALC wall panel has a unique shape and a steel frame 1 structure with very little steel material, which greatly improves the strength and stability of the wall panel and further strengthens the lightweight index. The central cage 11, as the core supporting structure, adopts a circular design and provides strong tensile and compressive resistance. The first vertical tie bars 12 and the transverse tie bars 14 are arranged on the vertical and transverse radial sides of the central cage 11 respectively, and are perpendicular to each other. This design ensures the stability of the steel frame 1 in all directions and transfers the force connecting the outer frame 2 around to the central cage 11 at the center of the steel frame 1, making the force more uniform. The introduction of the second vertical tie bars 13 further enhances the transverse shear resistance and vertical compressive resistance of the wall panel. This multi-level steel bar arrangement gives the reinforced ALC wall panel excellent overall strength and stability, and can effectively resist external loads and impacts.

[0060] (2) Construction simplicity and efficiency: This design continues the fast and convenient construction of prefabricated buildings and simplifies the construction process of existing ALC wall panels through structural optimization.

[0061] (3) Durability and earthquake resistance: This reinforced ALC wall panel design makes the wall panel have excellent durability and earthquake resistance. The steel skeleton 1 provides reliable tensile and compressive support inside, and can evenly bear the force of the four sides of the wall panel's connecting frame 2, and distribute the force of each side to the center of the steel skeleton 1, ensuring that the wall panel is evenly stressed and not easily deformed during long-term use, and the filled lightweight concrete filler 3 is also not easy to deform and crack. At the same time, the lightweight concrete filler 3 is tightly fitted with the steel skeleton 1 to form an integral internal support structure, which effectively disperses and absorbs external shocks and vibrations, and improves the earthquake resistance of the wall panel. This structure is particularly suitable for earthquake-prone areas and high-rise buildings. It can achieve a higher lightweight static load and provide reliable force support, which can significantly improve the safety of the building.

[0062] (4) Economic benefits: First, the prefabrication of the steel skeleton 1 and the prefabrication of the lightweight concrete reduce material waste and construction costs. Second, the modular production, transportation and installation methods improve construction efficiency, shorten the construction period and reduce labor costs. In addition, the high strength and durability of the reinforced ALC wall panels reduce maintenance and repair costs, extend the service life of the building, and further reduce long-term use or operation costs.

It is suitable for various prefabricated buildings or high-rise buildings that require lightweight, especially buildings that require high strength and high stability.

[0064] As one optional implementation,

[0065] Regarding the connection structure and connection method of the above-mentioned connection outer frame 2 and the side columns, upper beams, and floor slabs, as well as the splicing connection structure of two connection outer frames 2, this embodiment is as follows: Figure 1 and Figure 2 As shown, one of the vertical sides of the connecting outer frame 2 is set as the wall splicing side 21, and the other vertical side and two horizontal sides are set as the fixed side 22; a plurality of semicircular hole sleeves 211 are arranged in sequence on the wall splicing side 21; and a connecting bolt 4 is also included; the wall panels are assembled on two sides to be spliced ​​and connected, and the wall splicing sides 21 of the two connecting outer frames 2 are arranged oppositely, and the connecting bolt 4 is inserted into the two aligned semicircular hole sleeves 211, and the wall splicing sides 21 of the two connecting outer frames 2 are locked, so as to assemble and splice to form a wall; both sides of the fixed side 22 are set There is a connecting cavity 221; the side of the connecting cavity 221 facing the outside of the single-body assembled wall panel is an open side, and at least three connecting cavities 221 are arranged, and the three connecting cavities 221 are respectively located at the center of the length direction of the side and near the two ends; a connecting hole 222 is arranged at the position corresponding to the connecting cavity 221 on the connecting outer frame 2, and the connecting hole 222 is a semicircular hole; the connecting cavities 221 and the connecting holes 222 of the three fixed sides 22 are respectively used to connect and fix with the side columns, or the upper beams, or the floor slabs, by driving expansion bolts into the reserved holes, or by screws and the holes of the semi-embedded parts.

[0066] Regarding the specific structure of the central cage 11, this embodiment Figure 2 As shown, the central cage 11 is composed of at least two annular ribs 111 and a plurality of connecting ribs 112 to form a circular cage; the two annular ribs 111 are coaxially stacked, the plurality of connecting ribs 112 are evenly arranged along the circumference of the annular ribs 111, and the two ends of the connecting ribs 112 are respectively welded to the two annular ribs 111.

[0067] Specifically, the first vertical tie bars 12 and the transverse tie bars 14 are connected to the corresponding connecting bars 112 .

[0068] When applied, the steel skeleton 1 adopts a central cage 11 as the central core structural member, which serves as a support and withstands the tension or pressure applied by the four sides of the connected outer frame 2. The central cage 11 is a circular cage, and each relatively arranged first vertical tie 12 or transverse tie 14 is connected with a semicircular arch as a load-bearing seat, so that it can withstand a large tension or pressure (refer to the stress form of the arch bridge), so that the ALC wall panel still has a strong stress-bearing performance when using very few steel bars as a skeleton for reinforcement. The second vertical tie 13 attached to the transverse tie 14 on both sides is superimposed. Under the premise of ensuring lightweight, the stress-bearing performance of the ALC wall panel can still be improved, thereby forming a reinforced ALC wall panel.

[0073] Specifically, the surface reinforcement mesh 5 is a nylon fiber mesh or a steel wire mesh.

[0074] When in use, a surface reinforcement mesh 5 is embedded in the wrapping layer of the lightweight concrete filler 3. The mesh reinforces the lightweight concrete with relatively loose material and dense pores, so that when the lightweight concrete filler 3 is used or transported, it is possible to reduce cracks on the wall surface and increase the overall rigidity of the lightweight concrete.

[0075] The second embodiment of the reinforced ALC wall panel structure is as follows Figure 3 As shown, the difference between this embodiment and the first embodiment is that two of the opposite vertical sides of the connecting outer frame 2 are set as wall splicing sides 21, and the other two opposite horizontal sides are set as fixed sides 22; a plurality of semicircular hole sleeves 211 are arranged in sequence on the wall splicing side 21; it also includes a connecting bolt 4; the multi-faceted monomer assembly wall panels are continuously spliced ​​and connected, and the wall splicing sides 21 of the plurality of connecting outer frames 2 are arranged relatively, and the connecting bolt 4 is inserted into the two aligned semicircular hole sleeves 211, and the wall splicing sides 21 of the two adjacent connecting outer frames 2 are locked for assembling and splicing to form a continuous wall; connecting cavities 221 are set on both sides of the wall splicing side 21, and the connecting cavity 221 is set in the connecting interval 23 composed of two adjacent semicircular hole sleeves 211, and the connecting cavity 2 is arranged in at least three connecting intervals 23. 21; both sides of the fixed edge 22 are provided with connecting cavities 221, and there are at least three connecting cavities 221, which are respectively located at the center of the length direction of the fixed edge 22 and the vicinity of the two ends; the side of the connecting cavity 221 facing the outside of the single-body assembled wall panel is an open side, and a connecting hole 222 is provided at the position corresponding to the connecting cavity 221 on the connecting outer frame 2, and the connecting hole 222 is a semicircular hole; the connecting cavities 221 and the connecting holes 222 of the two fixed edges 22 are respectively used to connect and fix with the upper side beam or floor slab by driving expansion bolts into the reserved holes, or by screws and holes of semi-embedded parts; the connecting cavity 221 and the connecting holes 222 of the wall splicing side 21 close to the side column are used to connect and fix with the reserved holes on the side column by driving expansion bolts into the holes, or by screws and holes of semi-embedded parts on the side column.

[0076] During application, when three-sided single-body assembled wall panels are continuously spliced ​​and connected, the two adjacent wall splicing sides 21 are connected by connecting bolts 4 and semicircular hole sleeves 211, and when the single-body assembled wall panels at one end and one end are connected to the side columns of the building, they can be connected through the connecting cavity 221 and the connecting hole 222 between the semicircular hole sleeves 211, thereby realizing two connection forms of the wall splicing sides 21 of the single-body assembled wall panels.
