Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and in particular to a composite rock panel and a composite rock panel wall installation structure. Background Technology

[0002] As a new type of decorative material, sintered stone has been increasingly widely used in the construction and home decoration fields in recent years. Its rich textures, wear and stain resistance, and environmental friendliness and non-toxicity have gradually gained market favor. However, in the actual application of sintered stone, especially in wall installation, there are still many technical bottlenecks that need to be overcome.

[0003] Currently, the installation of sintered stone slabs on walls mostly employs the traditional wet-laying method. This method requires on-site pretreatment of the sintered stone slabs and the substrate, applying cement mortar or special adhesive before laying. The process is cumbersome, demands high technical skills from construction workers, and is inefficient. Furthermore, sintered stone slabs are inherently brittle and prone to cracking, easily resulting in chipping, breakage, and other damage during transportation and on-site installation, leading to material waste and increased costs. Wet-laying operations also generate a large amount of construction waste, such as waste adhesive and cutting debris, burdening the environment and failing to meet green construction requirements.

[0004] In addition, to improve the strength of sintered stone panels and reduce the breakage rate, prefabricated installation materials such as aluminum honeycomb composite sintered stone panels have emerged in the industry. Although these materials have achieved dry construction and breakage control to a certain extent, they still have problems such as high cost, large self-weight, and complex processes. They usually require a multi-layer adhesive composite structure, the production process is cumbersome, and the final product is heavy, increasing the load on the wall and the difficulty of installation, which restricts their large-scale promotion and application.

[0005] Therefore, how to overcome the limitations of existing slab installation technology and provide a lighter, more economical, more convenient and environmentally friendly prefabricated installation solution has become an urgent technical problem to be solved in this field. Utility Model Content

[0006] In response to the problems raised in the background art, the purpose of this utility model is to propose a composite rock slab and a composite rock slab wall installation structure, which has the advantages of improving installation efficiency, reducing damage rate, enhancing connection reliability, and achieving environmentally friendly construction.

[0007] To achieve this objective, the present invention adopts the following technical solution: A composite slab includes a slab layer, two alloy connecting strips, a polyurethane adhesive layer, and a fiber cloth layer; Two alloy connecting strips are respectively disposed on both sides of the rear surface of the rock slab layer, and the alloy connecting strips extend along the length direction of the rock slab layer; The polyurethane adhesive layer fills the space between the two alloy connecting strips and covers the rear surface of the two alloy connecting strips; The fiber cloth layer covers the side of the polyurethane adhesive layer away from the rock slab layer.

[0008] Preferably, the alloy connecting strip includes a first side plate, a connecting plate, and a second side plate; The first side plate and the second side plate are parallel to each other, and the connecting plate is disposed between the first side plate and the second side plate, and is perpendicular to the first side plate and the second side plate respectively; The second side plate is connected to the rock slab layer; The polyurethane adhesive layer fills the space between the two connecting plates and covers the two first side plates.

[0009] Preferably, the first side plate, one side of the connecting plate, and the second side plate form a filling groove, and the first side plate, the other side of the connecting plate, and the second side plate form a mounting groove. The filling groove is used to fill the polyurethane adhesive layer, and the mounting groove is used to assemble the composite rock panel wall.

[0010] Preferably, the filling groove is provided with protruding teeth, which extend along the length direction of the alloy connecting strip.

[0011] Preferably, the alloy connecting strip is connected to the rock slab layer by double-sided adhesive tape.

[0012] Preferably, the thickness of the rock slab layer is 3mm to 6mm; The thickness of the thickest part of the polyurethane adhesive layer is 10mm to 20mm; The alloy connecting strip is an aluminum alloy connecting strip.

[0013] A composite rock panel wall installation structure includes several keels, several columns, and the aforementioned composite rock panels; The keel extends horizontally and is installed on the wall by a first mounting member; several keels are arranged at intervals in the vertical direction. The columns extend vertically and are installed on the keel via a second mounting component. Several columns are spaced apart horizontally. The mounting grooves on both sides of the composite rock slab are respectively connected to the two adjacent columns.

[0014] Preferably, the column includes a first column plate, a column plate connecting plate, and a second column plate; The first column plate and the second column plate are parallel to each other, and the column plate connecting plate is vertically disposed between the first column plate and the second column plate; The horizontal cross-section of the column is I-shaped, and the first column plate, the column plate connecting plate and the second column plate form two left-right symmetrical mounting slots; When the composite rock slab is assembled with the column, the clamping groove is clamped to the mounting groove.

[0015] Preferably, one end of the first column plate is provided with an extension plate, the extension plate is integrally formed with the first column plate, and the side of the extension plate near the column plate connecting plate is provided with a second groove, the second groove extending along the length direction of the column; The second mounting component is a fixing screw. When the column and the keel are connected by the fixing screw, the nut of the fixing screw is located in the second groove and the nut does not protrude from the plane of the first column plate.

[0016] Preferably, a first groove is provided on the side where the keel connects to the column, and the first groove extends along the length direction of the keel; The first mounting component is an anchor bolt. When the keel and the wall are connected by the anchor bolt, the bolt cap is located in the first groove and does not protrude from the keel.

[0017] Compared with the prior art, one of the above technical solutions has the following beneficial effects: 1. By using two alloy connecting strips to replace the traditional heavy aluminum honeycomb or cement base layer, a "linear skeleton" structure is formed. While ensuring the core mechanical strength of the composite rock panel, the overall weight of the composite rock panel is greatly reduced, the load on the wall is reduced, and the installation operation is more convenient. 2. The alloy connecting strip has excellent bending resistance, and the polyurethane adhesive layer has superior structural strength, which can effectively absorb and disperse impact stress, preventing breakage, chipping, and the generation of hidden cracks due to deformation during handling and transportation, and greatly improving the toughness and durability of the material. 3. The composite rock slabs are directly connected to adjacent columns through prefabricated installation grooves on both sides, eliminating the need for on-site adhesive application or complex positioning. This reduces reliance on traditional masonry techniques and significantly speeds up installation compared to wet-laying and traditional composite panel processes, truly achieving fast and convenient prefabricated construction.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The following is in conjunction with the appendix Figures 1 to 6 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0025] A composite slab includes a slab layer 11, two alloy connecting strips 12, a polyurethane adhesive layer 13, and a fiber cloth layer 14. Two alloy connecting strips 12 are respectively disposed on both sides of the rear surface of the rock slab layer 11, and the alloy connecting strips 12 extend along the length direction of the rock slab layer 11; The polyurethane adhesive layer 13 fills the space between the two alloy connecting strips 12 and covers the rear surface of the two alloy connecting strips 12; The fiber cloth layer 14 covers the polyurethane adhesive layer 13 on the side away from the rock slab layer 11.

[0026] Alloy connecting strips 12 are arranged along the length of the slab layer 11, forming an anti-bending structure on both sides of the slab layer 11 through the high rigidity of the alloy connecting strips 12. A polyurethane adhesive layer 13 fills the space between the two alloy connecting strips 12 and completely covers the surface of the two alloy connecting strips 12. Specifically, the polyurethane adhesive layer 13 can be formed by on-site foaming of a two-component polyurethane adhesive, filling the space between the two alloy connecting strips 12 through its foaming properties. The polyurethane adhesive itself has structural bonding properties, eliminating the need for multiple layers (two or more) of adhesive application required in the existing fiberglass honeycomb composite slab production process. It bonds with the slab layer 11, alloy connecting strips 12, and fiber cloth layer 14 using its own adhesive properties. Simultaneously, the hardened polyurethane adhesive has micro-elasticity, which can absorb external impact energy through its elastic deformation capacity, providing a certain buffering effect when subjected to collisions. The polyurethane adhesive layer 13, placed on the surface of the slab layer 11, gives the composite slab higher strength and toughness. The fiber cloth layer 14 covers the surface of the polyurethane adhesive layer 13, which is equivalent to the protective layer and reinforcing layer of the bottom layer of the composite rock slab. Specifically, it can be made of glass fiber or carbon fiber woven cloth combined with epoxy resin. The high tensile strength of the fiber constrains the deformation of the polyurethane adhesive layer 13.

[0027] Specifically, the slab layer 11 serves as a decorative surface layer, while the alloy connecting strips 12 on both sides form a rigid support structure, bearing the main bending loads during handling and installation. A polyurethane adhesive layer 13 fills the spaces between the alloy connecting strips 12 and bonds to the surface of the slab layer 11. When subjected to external impact, the polyurethane adhesive layer 13 undergoes elastic deformation to disperse stress, preventing stress concentration that could lead to cracking of the composite slab layer 1. The fiber cloth layer 14 and the polyurethane adhesive layer 13 form a composite structure through interfacial adhesion. When the polyurethane adhesive layer 13 is compressed, the fiber tension of the fiber cloth layer 14 resists deformation, forming a two-way mechanical constraint. After the surface of the alloy connecting strips 12 is covered with the adhesive layer, it together with the fiber cloth layer 14 forms a flexible transition interface, reducing the internal stress caused by the difference in thermal expansion coefficients between the metal and the slab layer 11.

[0028] Compared with existing technologies, this utility model uses two alloy connecting strips 12 to replace the traditional heavy aluminum honeycomb or cement base layer, forming a "linear skeleton". Combined with a lightweight polyurethane adhesive layer 13, the overall weight of the composite rock slab 1 is reduced. The composite structure of the polyurethane adhesive layer 13 and the fiber cloth layer 14 replaces the traditional multi-layer adhesive process, simplifying the production process while improving impact resistance.

[0029] Furthermore, the alloy connecting strip 12 includes a first side plate 121, a connecting plate 122, and a second side plate 123; The first side plate 121 and the second side plate 123 are parallel to each other, and the connecting plate 122 is disposed between the first side plate 121 and the second side plate 123, and is perpendicular to the first side plate 121 and the second side plate 123 respectively. The second side plate 123 is connected to the rock slab layer 11; The polyurethane adhesive layer 13 fills the space between the two connecting plates 122 and covers the two first side plates 121.

[0030] The parallel first side plate 121 and second side plate 123 are connected by a vertical connecting plate 122 to form an I-shaped cross-section, creating a three-dimensional frame with torsional stiffness. The polyurethane adhesive layer 13 filling between the two connecting plates 122 refers to the adhesive material forming a continuous bonding interface inside the alloy connecting strip 12. This can be achieved using a two-component polyurethane foam injection process, and its encapsulating filling can form a three-dimensional adhesive network. Furthermore, the upward wrapping of the polyurethane adhesive layer 13 around the first side plate 121 can also form a mechanical interlocking mechanism similar to mortise and tenon joints.

[0031] Furthermore, the first side plate 121, one side of the connecting plate 122 and the second side plate 123 form a filling groove 1201, and the other side of the first side plate 121, the connecting plate 122 and the second side plate 123 form a mounting groove 1202. The filling groove 1201 is used to fill the polyurethane adhesive layer 13, and the mounting groove 1202 is used to cooperate in the installation to form a composite rock slab wall.

[0032] The filling groove 1201 refers to a U-shaped opening structure formed by a portion of the inner wall surface of the first side plate 121, a single side wall surface of the connecting plate 122, and a portion of the inner wall surface of the second side plate 123. Its opening direction faces the center of the slab layer 11, and it is used to accommodate and restrict the flow range of the polyurethane adhesive layer 13 before curing. The mounting groove 1202 refers to a U-shaped opening structure formed by another portion of the inner wall surface of the first side plate 121, another side wall surface of the connecting plate 122, and another portion of the inner wall surface of the second side plate 123. Its opening direction faces away from the center of the slab layer 11, and it is used to form a mechanical interlock with the column during the installation of the composite slab wall.

[0033] Specifically, after the alloy connecting strip 12 is fixed to the surface of the slab layer 11, the polyurethane adhesive layer 13 is injected into the interior of the filling groove 1201. The sidewalls of the filling groove 1201 constrain the adhesive to diffuse outward, ensuring that the polyurethane adhesive forms a uniform thickness adhesive layer after curing. The two mounting grooves 1202 of the alloy connecting strips on both sides have symmetrical outward openings, forming a complementary interlocking connection with the column during the installation of the composite slab 1. The lateral positioning of the composite slab is achieved through the limiting walls on both sides of the column. The connecting plate 122 serves as a separating structure, with its two side walls forming the boundaries between the filling groove 1201 and the mounting groove 1202, thus physically separating the adhesive filling operation from the slab assembly operation.

[0034] Furthermore, the filling groove 1201 is provided with protruding teeth 124, which extend along the length direction of the alloy connecting strip 12.

[0035] The protruding teeth 124 refer to regular or irregular shaped protrusions, such as triangles, trapezoids, or waves, provided on the inner wall surface of the filling groove 1201, with a height of 0.5mm to 2mm. The protruding teeth 124 increase the contact area between the polyurethane adhesive layer 13 and the filling groove 1201, thereby creating a mechanical interlocking effect.

[0036] Specifically, when the polyurethane adhesive layer 13 cures within the filling groove 1201, the adhesive material encapsulates the three-dimensional structure of the protrusions 124, forming an interlocking interface. When the composite rock slab 1 is subjected to external force, the interlocking effect between the protrusions 124 and the polyurethane adhesive layer 13 can disperse shear stress.

[0037] Furthermore, the alloy connecting strip 12 is connected to the rock slab layer 11 by double-sided adhesive tape 15.

[0038] After positioning alloy connecting strips 12 on both sides of the surface of the slab layer 11, they are directly pressed onto the surface of the slab layer 11 by applying double-sided adhesive tape 15 pre-attached to the bottom surface of the alloy connecting strips 12. The pressure-sensitive properties of the double-sided adhesive tape 15 enable it to generate adhesive force immediately under contact pressure, eliminating the need for the coating, spreading, and curing processes of traditional adhesives.

[0039] Furthermore, the thickness of the rock slab layer 11 is 3mm to 6mm; The thickness of the thickest part of the polyurethane adhesive layer 13 is 10mm to 20mm; The alloy connecting strip 12 is an aluminum alloy connecting strip.

[0040] The thickness of the slab layer 11 is limited to a range of 3 mm to 6 mm, allowing the slab layer 11 to meet bending resistance requirements while reducing material usage. Because the polyurethane adhesive layer 13 is partially embedded within the filling groove 1201 and needs to cover the first side plate 121 of the alloy connecting strip, the polyurethane adhesive layer 13 exhibits inconsistent thickness. The portion bonded to the surface of the slab layer 11 is the thickest. By limiting the thickness of the thickest portion of the polyurethane adhesive layer 13, the cured polyurethane adhesive layer 13 can be ensured to possess elasticity, support, and cushioning capabilities. The alloy connecting strip 12 can specifically be made of 6063-T5 aluminum alloy profile, a material that reduces component weight while ensuring tensile strength.

[0041] A composite rock panel wall installation structure includes several keels 2, several columns 3 and the aforementioned composite rock panel 1; The keel 2 extends horizontally and is installed on the wall via the first mounting member 41. Several keels 2 are spaced apart vertically. The column 3 extends vertically and is installed on the keel 2 via the second mounting member 42. Several columns 3 are spaced apart horizontally. The mounting grooves 1202 on both sides of the composite rock slab 1 are respectively connected to the two adjacent columns 3.

[0042] The keel 2 refers to the horizontal support component arranged along the building wall, which can be made of metal profiles and is fixed to the wall by the first mounting piece 41 to form the foundation bearing surface. The column 3 refers to the vertical support component set perpendicular to the keel 2 and is connected to the keel 2 by the second mounting piece 42 to form a grid support system; its horizontally spaced arrangement forms standardized installation nodes.

[0043] Specifically, the horizontal keel 2 is fixed to the building wall via the first mounting piece 41, forming multiple parallel support bands. The vertical column 3 is vertically fixed to the keel 2 via the second mounting piece 42. The composite slab 1 is directly fitted into the adjacent column 3 via prefabricated mounting grooves 1202 on both sides, achieving rapid positioning and installation of the slab unit. The grid support system formed by the keel 2 and the column 3 replaces the adhesive layer of the traditional wet-laying process, eliminating the need for on-site glue application or cutting during installation. The composite slab 1 is fixed by mechanical snap-fit, avoiding the waiting time for adhesive curing and eliminating stress concentration problems caused by uneven adhesive layer thickness.

[0044] Furthermore, the column 3 includes a first column plate 31, a column plate connecting plate 32, and a second column plate 33; The first column plate 31 and the second column plate 33 are parallel to each other, and the column plate connecting plate 32 is vertically disposed between the first column plate 31 and the second column plate 33. The horizontal cross-section of the column 3 is in the shape of an "I". The first column plate 31, the column plate connecting plate 32 and the second column plate 33 form two left-right symmetrical mounting slots 30. When the composite rock slab 1 is assembled with the column 3, the clamping groove 30 is clamped and connected to the mounting groove 1202.

[0045] The I-shaped cross-section of column 3 refers to a cross-sectional shape with a symmetrical support structure formed by two parallel first column plates 31 and second column plates 33 connected by a vertical column plate connecting plate 32. This structure reduces material usage while ensuring bending strength. The mounting groove 30 is a recessed space enclosed by the first column plate 31, the column plate connecting plate 32, and the second column plate 33. This groove forms a geometric interlocking relationship with the mounting groove 1202 of the composite rock slab to restrict displacement.

[0046] The first column plate 31 and the second column plate 33 are arranged in parallel to form the front and rear support surfaces of the column. The column plate connecting plate 32 connects the two vertically to form an I-shaped cross-section. This cross-sectional shape allows the column 3 to form symmetrically distributed mounting slots 30 in the horizontal direction. The two symmetrical mounting slots 30 allow two composite rock panels 1 to be inserted simultaneously from the left and right sides of the column 3 without the need to adjust the direction or use auxiliary positioning tools during installation. The geometric fit between the mounting slots 30 and the mounting grooves 1202, through the combined action of friction and structural restraint, prevents the composite rock panels 1 from falling off under vibration or external impact.

[0047] Furthermore, one end of the first column plate 31 is provided with an extension plate, which is integrally formed with the first column plate 31. The extension plate is provided with a second groove 311 on the side near the column plate connecting plate 32, and the second groove 311 extends along the length direction of the column 3. The second mounting component 41 is a fixing screw. When the column 3 and the keel 2 are connected by the fixing screw, the nut of the fixing screw is located in the second groove 311, and the nut does not protrude from the plane where the first column plate 31 is located.

[0048] The extension plate refers to a plate-like structure that extends outward from the end of the first column plate. Specifically, it can be integrally formed with the first column plate 31 through stamping or extrusion molding processes, and is used to provide additional support area when installing fixing screws. The second groove 311 is formed in the extension plate, which is opened along the length of the column 3, and its depth is set to accommodate the nut height of the fixing screw.

[0049] Specifically, during the assembly of the column 3 and the keel 2, the fixing screw passes through the column 3 and the keel 2 in sequence in front of the wall. When the fixing screw is fully tightened, its nut is restricted within the depth space of the second groove 311, so that the top of the nut is flush with the outer surface of the first column plate 31.

[0050] Due to the different requirements of decorative wall panels, the specific number and installation position of the required keel 2 are not the same. Therefore, the second groove 311 is opened along the length of the column 3, which allows the fixing screws to be effectively hidden in the second groove 311 when the column 3 is installed with the keel 2 at different positions.

[0051] In some specific embodiments, the cross-sectional shape of the second groove 311 can be trapezoidal or rectangular, and its bottom can be provided with anti-slip texture to increase the friction of the head of the fixing screw. The thickness of the extension plate can be consistent with that of the first column plate 31. The countersunk angle of the fixing screw can be matched with the inclination angle of the side wall of the second groove 311, for example, a 45-degree countersunk screw can be used to mate with the trapezoidal second groove 311.

[0052] Furthermore, a first groove 21 is provided on the side where the keel 2 is connected to the column 3, and the first groove 21 extends along the length direction of the keel 2; The first mounting component 41 is an anchor bolt. When the keel 2 is connected to the wall through the anchor bolt, the bolt cap is located in the first groove 21 and the bolt cap does not protrude from the keel 2.

[0053] The first groove 21 is a continuous groove-shaped structure formed on the connecting side of the keel 2. Its depth matches the thickness of the anchor head and is used to accommodate the anchor head and limit its exposure.

[0054] Specifically, during the installation of the keel 2, the anchor bolt passes through the keel 2 and is driven into the wall, with the bolt cap pressed into the first groove 21. Because the depth of the first groove 21 matches the thickness of the bolt cap, the top surface of the bolt cap remains flush with (or does not exceed) the outer surface of the keel 2, preventing unevenness on the installation surface of the keel 2 due to the bolt cap protruding outwards. The continuous extension of the first groove 21 along the length of the keel 2 allows the anchor bolt to be fixed at any position without pre-setting installation points, improving construction flexibility.

[0055] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
