[0031] This utility model proposes an autoclaved lightweight aerated concrete panel 10.
[0032] Please see Figures 1 to 3 , Figure 6 In one embodiment of the present invention, the autoclaved aerated concrete (AAC) panel 10 includes a panel body 100 and a wedge block 200. The panel body 100 has two opposing first side surfaces 110 and two opposing second side surfaces 120. The second side surfaces 120 are connected between the two first side surfaces 110. The first side surfaces 110 are provided with wedge grooves 130, which extend along the length direction of the first side surfaces 110 and penetrate through the second side surfaces 120. The wedge block 200 is separately disposed from the panel body 100, and two adjacent panel bodies 100 are assembled into one unit by means of the wedge block 200. The wedge block 200 includes two opposing wedge portions 210 in the groove depth direction of the wedge groove 130. The small ends of the two wedge portions 210 are connected, and the wedge portions 210 can be inserted into the wedge groove 130 along the extension direction of the wedge groove 130.
[0033] Specifically, Autoclaved Lightweight Aerated Concrete Panels (ALC panels) are a new type of building material. ALC panels are made by adding gas-generating materials such as aluminum powder to concrete and curing them under high temperature and high pressure to form a porous structure, thereby achieving lightweight and excellent thermal insulation effects.
[0034] The autoclaved aerated concrete (AAC) panel 10 includes a panel body 100 and wedge-shaped blocks 200. The wedge-shaped blocks 200 are separately disposed from the panel body 100, and two adjacent panel bodies 100 are assembled into one unit by means of the wedge-shaped blocks 200. A first side surface 110 and a second side surface 120 are formed on the periphery of the panel body 100 and connect the two surfaces of the panel body 100. The second side surface 120 connects between the two first side surfaces 110. The thickness of the panel body 100 is equal to the width of the first side surface 110 and the second side surface 120.
[0035] A wedge-shaped groove 130 is provided on the first side surface 110 of the plate body 100. The wedge-shaped groove 130 extends along the length direction of the first side surface 110 and penetrates the second side surface 120, so that the wedge-shaped block 200 can be inserted into the wedge-shaped groove 130 from the second side surface 120 and be limitedly engaged with the wedge-shaped groove 130. The wedge-shaped block 200 is manufactured separately from the plate body 100. The wedge-shaped block 200 is composed of two opposing wedge-shaped portions 210. The wedge-shaped portions 210 are trapezoidal in shape. The wider end of the wedge-shaped portion 210 is the large end of the wedge-shaped portion 210, corresponding to the upper base of the trapezoid; the smaller end of the wedge-shaped portion 210 is the small end of the wedge-shaped portion 210, corresponding to the lower base of the trapezoid. The small ends of the two wedge-shaped portions 210 are connected, meaning that the entire wedge block 200 is narrowest in the middle and gradually widens towards both ends, making it easier for the wedge block 200 to be inserted into the wedge groove 130 on the plate body 100. Once inserted, the wedge-shaped portion 210 and the wedge groove 130 engage in a wedge-shaped fit, providing a secure locking effect. Thus, the two wedge-shaped portions 210 of the wedge block 200 can connect two adjacent plate bodies 100 together.
[0036] During installation, adjacent panel bodies 100 can be quickly joined using wedge blocks 200 and wedge grooves 130. Adjacent panel bodies 100 are arranged in parallel, with their two adjacent first side faces 110 pressed together. The two wedge grooves 130 are aligned and extend in parallel. The wedge block 200 is pushed in from the second side face 120 (the face where the end face of the wedge groove 130 is located) along the length of the wedge groove 130, so that the two wedge-shaped portions 210 of the wedge block 200 are correspondingly inserted into the wedge grooves 130 of the two adjacent panel bodies 100. This achieves the initial connection of the adjacent panel bodies 100. This connection method is simple, quick, and tight, effectively preventing relative displacement of the two panel bodies 100 during subsequent construction. The connection of the wedge blocks 200 and wedge grooves 130 has already provided initial positioning for the panel bodies 100, making it easier and faster for installers to perform further fixing and installation, greatly improving installation efficiency.
[0037] The individual wedge block 200 is small in length and volume, occupying little space and making installation more convenient and quick, even in confined spaces, thus improving the installation flexibility of the autoclaved lightweight aerated concrete (AAC) panel 10. Furthermore, the wedge block 200 and the panel body 100 are separate components; if one is damaged, it can be replaced directly, rather than the entire panel being replaced, thereby reducing resource waste and maintenance costs. In addition, the combined use of the wedge groove 130 and the wedge block 200 helps reduce leakage at the joint between the two panel bodies 100, improving the building's waterproofing and moisture-proofing performance.
[0038] The technical solution of this utility model allows the wedge-shaped part 210 to be inserted into the wedge-shaped groove 130 along the extension direction of the wedge-shaped groove 130, so that two adjacent plate bodies 100 can be assembled into one by the wedge-shaped block 200, thereby realizing the pre-installation of two adjacent plate bodies 100 and improving the installation efficiency of autoclaved lightweight aerated concrete panels 10.
[0039] In one implementation, please refer to Figure 2 At least two wedge blocks 200 are distributed along the extension direction of the wedge groove 130.
[0040] Multiple wedge blocks 200 can be spaced apart or connected to each other. By arranging multiple wedge blocks 200 in the wedge grooves 130, sufficient support force can be provided to cope with larger loads or stresses, and these loads or stresses can be distributed more evenly, significantly increasing the connection strength and stability between adjacent plate bodies 100. Multiple wedge blocks 200 help ensure precise alignment between plates, reduce the risk of misalignment between plates due to manufacturing errors or installation deviations, and ensure the integrity and flatness of the structure.
[0041] In other embodiments, two adjacent plate bodies 100 may also be initially connected by a single wedge block 200.
[0042] In one implementation, please refer to Figure 2 and Figure 7 Two adjacent wedge blocks 200 are connected by a threaded structure.
[0043] Adjacent wedge blocks 200 are connected by a threaded structure, further enhancing the stability and integrity of the plate body 100. Specifically, each wedge block 200 has a threaded post 230 at one end along the length of the wedge groove 130, and a matching threaded hole 220 at the opposite end. During installation, adjacent wedge blocks 200 can be screwed together using the threaded post 230 and the threaded hole 220 to form a continuous and robust whole. The threaded connection allows adjacent wedge blocks 200 to fit tightly, greatly improving the stability and load-bearing capacity of the entire structure, reducing the risk of loosening due to external factors, and providing greater stability and safety for the building. Of course, the threaded structure can also take other forms, such as having holes in both adjacent wedge blocks 200, through which a double-ended bolt is passed and secured with a nut.
[0044] In other embodiments, two adjacent wedge blocks 200 are snapped together or connected by magnetic attraction.
[0045] In one implementation, please refer to Figures 3 to 5 The autoclaved lightweight aerated concrete panel 10 also includes a sealing structure, which is located at both ends of the first side 110 in the width direction.
[0046] By setting sealing structures at both ends of the first side 110 in the width direction, moisture can be effectively prevented from seeping through the gaps between two adjacent panel bodies 100, thereby improving the waterproofness and durability of the building. The gaps between two adjacent panel bodies 100 are filled with sealing structures, reducing the sound propagation path and thus improving the sound insulation performance of the wall. Simultaneously, it helps reduce heat loss through the gaps, improving the building's thermal insulation effect and thus reducing energy consumption. Furthermore, the wedge-shaped groove 130 is located between the two sealing structures, which effectively prevent moisture from seeping into the wedge-shaped groove 130, reducing the risk of damage to the wedge-shaped block 200 due to water immersion.
[0047] In one implementation, please refer to Figures 3 to 5 The sealing structure includes a sealing groove 140 and a sealing element 300. The sealing groove 140 is located on the first side 110, and the sealing element 300 is located inside the sealing groove 140.
[0048] Each plate body 100 has two sealing grooves 140 on its first side surface 110 for placing the sealing element 300. The two sealing grooves 140 are distributed along the width direction of the first side surface 110 and extend along the length direction of the first side surface 110. The sealing grooves 140 provide a fixed installation position for the sealing element 300, preventing misalignment, damage, or deformation of the sealing element 300; at the same time, they also prevent the sealing element 300 from being too large, resulting in a large gap at the joint of the two plate bodies 100. The sealing element 300 has excellent waterproofness, weather resistance, and a certain degree of elasticity. The sealing element 300 can be configured as a waterproof adhesive or a sealing strip, and the sealing strip can be made of polyurethane foam, silicone sealant, butyl rubber, etc. These materials can maintain good physical properties under different temperature conditions and adapt to the slight displacement of the plate body 100 due to temperature changes or other factors.
[0049] In other embodiments, the sealing groove 140 may be omitted, and waterproof adhesive may be applied directly to the joint of the two plate bodies 100.
[0050] In one implementation, please refer to Figures 1 to 5 The plate body 100 is provided with mounting holes 150 that penetrate its surface.
[0051] The mounting holes 150 allow for the secure fixing of the ALC panels to the wall frame or other supporting structures using various types of fasteners. Prefabricated mounting holes 150 simplify on-site operations, reduce measurement and drilling time, and improve overall construction speed. Furthermore, compared to on-site drilling, prefabricated mounting holes 150 provide more precise positioning, preventing breakage or damage to the panel body 100 due to improper operation and extending the material's lifespan. The location and distribution of mounting holes 150 are typically determined based on specific project requirements and the dimensions of the panel body 100. Mounting holes 150 can be evenly distributed across the panel surface or concentrated in specific areas, such as near the edge of the panel body 100 or the center of the panel surface. When mounting holes 150 are distributed near the edge of the panel body 100, they should be staggered from the wedge grooves 130 and sealing grooves 140.
[0052] In one implementation, please refer to Figure 3 and Figure 4 The mounting hole 150 includes a countersunk section 151 and a threaded section 152, with the diameter of the countersunk section 151 being larger than the diameter of the threaded section 152.
[0053] The countersunk section 151 has a larger diameter and is used to accommodate the head of the fastener (such as the head of a countersunk bolt) so that the head of the fastener is fully embedded in the plate. This ensures that the surface of the ALC plate is smooth and free of protrusions after installation, which is not only aesthetically pleasing but also avoids safety hazards caused by protrusions. The threaded section 152 has a smaller diameter and matches the threaded portion of the fastener. It is used to connect the fastener and ensures the stability of the connection through the friction between the threads.
[0054] In other embodiments, the mounting hole 150 is a straight hole with a uniform diameter.
[0055] In one implementation, please refer to Figure 4 The mounting hole 150 includes two countersunk sections 151 and one threaded section 152. The two countersunk sections 151 are respectively located close to the two surfaces of the plate body 100, and the threaded section 152 is located between the two countersunk sections 151.
[0056] The design of the two countersunk sections 151 allows countersunk bolts to be used on both sides of the plate body 100, and can be installed and fixed from either side of the plate body 100, thereby improving the flexibility of installation.
[0057] In one implementation, please refer to Figures 2 to 4 The plate body 100 has internal reinforcing ribs.
[0058] The reinforcing ribs can be made of various materials, such as steel bars or wire mesh. Alternatively, other high-strength materials, such as glass fiber reinforced plastic (GFRP), may be used to meet different engineering requirements. By incorporating reinforcing ribs within the slab body 100, the bending resistance of the slab body 100 can be effectively improved, reducing bending deformation caused by external loads; it helps resist shear forces, protecting the slab body 100 from lateral forces; the presence of the reinforcing ribs makes the slab body 100 more robust, improving the overall integrity and stability of the structure.
[0059] In one implementation, please refer to Figures 2 to 4 The reinforcing ribs include intersecting and connected first reinforcing ribs 410 and second reinforcing ribs 420. The first reinforcing ribs 410 are arranged in a mesh and have at least two layers. Adjacent layers of first reinforcing ribs 410 are connected by second reinforcing ribs 420.
[0060] The first reinforcing ribs 410 are arranged in a mesh pattern, forming one or more mesh structures within the plate body 100. This mesh layout effectively disperses forces and improves the tensile and compressive strength of the plate body 100 in multiple directions. The first reinforcing ribs 410 are configured in at least two layers, meaning there are multiple mesh structures along the thickness direction of the plate body 100. This not only increases the stability of the plate body 100 but also provides stronger load-bearing capacity. The second reinforcing ribs 420 connect adjacent layers of the first reinforcing ribs 410, typically intersecting the first reinforcing ribs 410 at right angles or a certain angle. They can transfer loads between different layers, further enhancing the three-dimensional stability and overall rigidity of the plate body 100.
[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
