Description

Technical Field

[0001] This application relates to the field of composite panel technology, and more specifically, to an exterior wall composite panel with built-in connectors. Background Technology

[0002] With the promotion of green building concepts, exterior wall composite panels, as an important building material integrating insulation, decoration, and protection functions, have been widely used in construction projects. Exterior wall composite panels are typically made by extruding and bonding insulation materials and decorative panels, and are fixed to the building's exterior walls using dry-hanging or adhesive techniques, providing thermal insulation, decorative aesthetics, and weather protection. The application of composite panels simplifies the exterior wall construction process and reduces subsequent maintenance costs, making it an important choice for modern building exterior wall systems.

[0003] However, existing exterior wall composite panels face the following problems during long-term use: The insulation material is typically polyurethane, which is prone to insufficient filling during foaming, resulting in incomplete adhesion between the insulation layer and the decorative panel, leading to cracks after a period of use. Simultaneously, the insulation layer and decorative panel are bonded together with adhesive, and the aforementioned cracks accelerate adhesive aging, causing it to fail and resulting in delamination and detachment of the panels on both sides of the insulation layer, severely affecting structural stability and posing safety hazards. Furthermore, the installation of existing exterior wall composite panels is difficult due to their height, requiring highly specialized lifting operations. The current common practice on construction sites is to install external anchors for vertical lifting; however, this method damages the panel finish, affecting the overall aesthetic appearance of the building's exterior. Utility Model Content

[0004] To address the aforementioned problems, the present invention provides an exterior wall composite panel with built-in connectors, thus solving the problem of poor structural stability in existing exterior wall composite panels. The panel comprises an inner panel, an insulation layer, and an outer panel connected sequentially. Multiple connectors are provided within the insulation layer. Each connector includes a connecting section and contact sections symmetrically arranged at both ends of the connecting section. The contact sections are conical, and the connecting sections are cylindrical; the diameter of the contact sections gradually decreases towards the connecting section. The end faces of the two contact sections of the connector are respectively connected to the outer panel and the inner panel using adhesive.

[0005] Preferably, the angle between the outer surface of the contact section and the outer surface of the connecting section is α, where 90°<α≤170°.

[0006] Preferably, at least one fixing rod is provided inside the insulation layer, the fixing rod is perpendicular to the bottom end of the insulation layer, and one end of the fixing rod is provided with a lifting ring.

[0007] Preferably, the length of the fixing rod is the same as the length of the insulation layer.

[0008] Preferably, positioning elements and overlapping elements are symmetrically provided on both sides of the insulation layer; the positioning element cooperates with the overlapping element of one of its adjacent panels, and the overlapping element cooperates with the positioning element of another adjacent panel.

[0009] Preferably, both the positioning component and the overlapping component are hollow boxes with one side open; the positioning component has a positioning post inside, and the overlapping component has a rotating shaft inside, with an overlapping handle connected to the positioning post of the adjacent plate; the outer plate has an operating hole corresponding to the rotating shaft.

[0010] Preferably, the insulation layer is made of polyurethane, the inner panel is made of solid wood or fiber cement board, and the outer panel is made of marble, ceramic tile or fiber cement board.

[0011] Preferably, the connector is made of PC material.

[0012] Preferably, the multiple connectors are evenly spaced.

[0013] The beneficial effects of this utility model are as follows: The insulation layer of the exterior wall composite panel is equipped with multiple connectors. These connectors and adhesives tightly connect the insulation layer to the outer and inner panels, reducing the risk of detachment and improving the overall structural stability of the exterior wall composite panel. Each connector includes a connecting section and a contact section, with the contact section being a cone. When the exterior wall composite panel is subjected to external impact, the force is evenly distributed along the inclined surface of the contact section, preventing the force from concentrating in a localized area and ensuring the structural integrity and safety of the exterior wall composite panel. Through the cooperation of fixing rods, lifting rings, and a hoist, the exterior wall composite panel can be quickly and vertically lifted. The lifting operation is convenient, reducing the number of adjustments during vertical installation, improving construction efficiency, and resulting in a high degree of appearance integrity and aesthetics for the exterior wall composite panel. Through the cooperation of positioning and overlapping components, adjacent panels can be quickly connected. The number of panels can be flexibly adjusted according to the needs of different exterior wall sizes, making it widely applicable. Attached Figure Description

[0023] The present application will now describe an exterior wall composite panel with built-in connectors provided in an embodiment.

[0024] Please see Figure 1 and Figure 2This is a schematic diagram of the structure of the present invention. The exterior wall composite panel with built-in connectors includes an inner panel 1, an insulation layer 2, and an outer panel 3 connected in sequence. Multiple connectors 4 are provided within the insulation layer 2. Each connector 4 includes a connecting section 401 and contact sections 402 symmetrically arranged at both ends of the connecting section 401. The contact section 402 is conical, and the connecting section 401 is cylindrical. The diameter of the contact section 402 gradually decreases along the direction approaching the connecting section 401. The end faces of the two contact sections 402 of the connector 4 are connected to the outer panel 3 and the inner panel 1 respectively by adhesive. Specifically, the insulation layer 2 is tightly connected to the outer panel 3 and the inner panel 1 by the connectors 4 and adhesive. Even if gaps exist during polyurethane filling, the connectors 4 and adhesive ensure a tight fit between the outer panel 3, the inner panel 1, and the insulation layer 2, reducing the risk of detachment of the outer panel 3 and the inner panel 1 and improving the overall structural stability of the exterior wall composite panel. When the exterior wall composite panel is subjected to external impact, the external force will be evenly distributed along the inclined surface due to the conical structure of the contact surface, avoiding the concentration of external force in a local area. This ensures that the outer panel 3 and the inner panel 1 can still maintain a stable connection when subjected to large tensile forces, thus ensuring the integrity and safety of the exterior wall composite panel structure.

[0025] Furthermore, the angle between the outer surface of the contact section 402 and the outer surface of the connecting section 401 is α, where 90° < α ≤ 170°. In this embodiment, the angle between the outer surface of the contact section 402 and the outer surface of the connecting section 401 is 120°. Specifically, when 90° < α ≤ 170°, the contact section 402 can quickly disperse the load when the exterior wall composite panel is subjected to external force, avoiding stress concentration and ensuring the structural stability of the entire connector 4.

[0026] Furthermore, at least one fixing rod 8 is provided inside the insulation layer 2. The fixing rod 8 is perpendicular to the bottom end of the insulation layer 2, and one end of the fixing rod 8 is provided with a hanging ring 5. Please refer to [link / reference]. Figure 4 This is a structural diagram of the fixing rod 8 and the outer panel 3. In this embodiment, there are two fixing rods 8, symmetrically arranged within the insulation layer 2. The fixing rods 8 are specifically angle steel, and are connected to the outer panel 3 using special adhesive according to the material of the outer panel 3. In use, the steel wire is passed through the lifting ring 5, and the hoist vertically lifts the entire exterior wall composite panel using the steel wire. The lifting operation is convenient, reducing the number of adjustments during vertical installation and improving construction efficiency. After vertical installation is completed, the corresponding lifting ring 5 is cut off to ensure the integrity and aesthetics of the exterior wall composite panel.

[0027] Furthermore, the length of the fixing rod 8 is the same as the length of the insulation layer 2, ensuring that the entire insulation layer 2 is evenly stressed during lifting, thus achieving stable lifting. In addition, when using small pieces (such as stone, tiles, etc.) that need to be spliced ​​together, the insufficient strength of the polyurethane in the middle layer of the exterior wall composite panel leads to insufficient panel strength. The use of the fixing rod 8 successfully solves the problem of insufficient strength of the exterior wall composite panel.

[0028] Please see Figure 3 This is a structural diagram showing the interaction between the positioning element 6 and the overlapping element 7. Furthermore, the insulation layer 2 is symmetrically provided with positioning elements 6 and overlapping elements 7 on both sides. The positioning element 6 engages with the overlapping element 7 of one adjacent panel, and the overlapping element 7 engages with the positioning element 6 of another adjacent panel. Through the interaction of the positioning element 6 and the overlapping element 7, adjacent panels can be quickly connected. The number of panels can be flexibly adjusted according to the needs of different sized exterior walls, making it widely applicable.

[0029] Furthermore, both the positioning component 6 and the overlapping component 7 are hollow boxes with one open side. The positioning component 6 contains a positioning post 601, and the overlapping component 7 has a rotatably connected shaft 701. The shaft 701 is connected to an overlapping handle 702 that mates with the positioning post 601 of the adjacent board. The outer panel 3 has an operating hole corresponding to the shaft 701. Specifically, when installing adjacent boards, first align the two boards, ensuring that the positioning component 6 of one board aligns with the overlapping component 7 of the other board. Then, the worker inserts a wrench or other rotating tool into the operating hole, engaging the rotating tool with the shaft 701 to rotate the overlapping handle 702. This causes the free end of the overlapping handle 702 to rotate into the inner cavity of the corresponding positioning component 6 of the adjacent board, mates with the positioning post 601, and thus fixes the two adjacent boards together. This design can adapt to different construction environments and working conditions, has a wide range of applications, and the fixing operation is simple and convenient, improving construction efficiency. After the adjacent panels are installed, only the operation hole is left on the surface of the outer panel 3. Compared with the traditional connection method, this ensures the integrity of the appearance and improves the aesthetics of the exterior wall composite panels.

[0030] Furthermore, the insulation layer 2 is made of polyurethane or other insulation materials, the inner panel 1 is made of solid wood or fiber cement board, and the outer panel 3 is made of marble, ceramic tile, or fiber cement board. Different adhesives are selected according to the different materials of the outer panel 3 and the inner panel 1 to ensure the stability of the connection between the connector 4 and the outer panel 3 and the inner panel 1.

[0031] In one embodiment, the exterior wall composite panel includes an inner panel 1, an insulation layer 2, and an outer panel 3 connected in sequence. The insulation layer 2 is made of polyurethane, the inner panel 1 is made of solid wood, and the outer panel 3 is made of marble.

[0032] In one embodiment, the exterior wall composite panel includes an inner panel 1, an insulation layer 2, and an outer panel 3 connected in sequence. The insulation layer 2 is made of polyurethane, the inner panel 1 is made of solid wood, and the outer panel 3 is made of ceramic tile.

[0033] In one embodiment, the exterior wall composite panel includes an inner panel 1, an insulation layer 2, and an outer panel 3 connected in sequence. The insulation layer 2 is made of polyurethane, the inner panel 1 is made of fiber cement board, and the outer panel 3 is made of fiber cement board.

[0034] Furthermore, connector 4 is made of PC material. PC material has stable performance and a certain degree of elasticity. When subjected to external impact, it can buffer the impact through its own elastic deformation, reducing the risk of structural damage caused by external impact.

[0035] Specifically, multiple connectors are evenly distributed at 4 intervals to ensure that the load borne by the exterior wall composite panel is evenly distributed to various parts, avoiding excessive local stress and extending the service life of the panel.

[0036] The processing procedure of this utility model is as follows: First, the inner panel 1 is placed on the lower mold platform, and then the outer panel 3 is placed on top of the frame. Aluminum alloy mold strips are provided around the lower mold platform to prevent polyurethane leakage. At this time, a cavity for injecting insulation material is formed between the outer panel 3, the inner panel 1, and the mold strips. Multiple connectors 4 are placed sequentially into the cavity. Based on the material characteristics of the outer panel 3 and the inner panel 1, a special adhesive is selected to firmly bond the connectors 4 to the outer panel 3 and the inner panel 1 respectively. Polyurethane is then injected from the side of the cavity to fill it completely. Then, the upper mold platform is pressed down to perform a pressing operation. After the polyurethane has cured, the mold is opened, completing the initial processing of the exterior wall composite panel.

[0037] In this invention, the insulation layer 2 of the exterior wall composite panel is equipped with multiple connectors 4. These connectors 4 and adhesive tightly connect the insulation layer 2 to the outer panel 3 and inner panel 1, reducing the risk of detachment of the outer panel 3 and inner panel 1 and improving the overall structural stability of the exterior wall composite panel. Each connector 4 includes a connecting section 401 and a contact section 402, with the contact section 402 being a cone. When the exterior wall composite panel is subjected to external impact, the force is evenly distributed along the inclined surface of the contact section 402, preventing the force from concentrating in a localized area and ensuring the integrity and safety of the exterior wall composite panel structure. Through the cooperation of the fixing rod 8, lifting ring 5, and hoist, the exterior wall composite panel can be quickly and vertically lifted. The lifting operation is convenient, reducing the number of adjustments during vertical installation, improving construction efficiency, and resulting in a high degree of appearance integrity and aesthetics for the exterior wall composite panel. Through the cooperation of the positioning component 6 and the overlapping component 7, adjacent panels can be quickly connected. The number of panels can be flexibly adjusted according to the needs of different sized exterior walls, making it widely applicable.
