Abstract
Description
Technical Field
[0001] This application relates to exterior wall systems, and more particularly to an insulated decorative panel exterior wall system. Background Technology
[0002] Thermal insulation and decorative composite panels are a new type of green building material that integrates decoration and energy saving, and are widely used in the field of building exterior wall insulation. Traditional thermal insulation and decorative panels are generally installed and fixed using an installation method that primarily relies on adhesive mortar bonding, supplemented by anchor fixing. Traditional anchoring methods for thermal insulation and decorative panels mainly include slotted anchors and milled edge anchors. The effective anchoring width of slotted anchors is approximately 20mm–30mm, and the effective anchoring depth is approximately 3mm–10mm. The effective anchoring width of milled edge anchors is approximately 30mm–50mm, and the effective anchoring depth is approximately 2mm–4mm. Grooving anchors require grooving at least two opposite sides of the board. After grooving, the thickness of the board at the anchoring stress point is less than half the original thickness. Moreover, to prevent edge chipping of the decorative layer at the grooved area, the center of the grooving is often offset towards the insulation layer, resulting in the board thickness at the anchoring stress point being less than 1 / 3 of the original thickness. Furthermore, to facilitate installation, installers often make the grooves very wide. Due to the influence of the grooving position and effective anchoring area, the anchoring strength of this type of grooving anchor is very low, and may even fail to meet the minimum anchoring force requirements specified in the standard. Milling anchors require milling the top and bottom opposite sides of the board, which is a complicated process. In addition, due to the influence of processing dimensional deviations and wall deviations on the construction site, the anchor often experiences problems with loose anchoring, thus creating safety hazards.
[0003] Traditional thermal insulation decorative panel systems use point anchoring, with anchors installed at the panel seams and distributed in a point-like pattern, typically 6 to 8 per square meter. This anchoring method has relatively low anchoring force and limited fixation for the thermal insulation decorative panels. In extreme situations such as incomplete adhesion of the bonding mortar, failure of the bonding mortar, or complete burning of the insulation layer in a fire, this anchoring method cannot effectively fix the panels, causing the thermal insulation decorative panels to detach from the wall or fall off during a fire, posing a significant threat to people's property and personal safety. Summary of the Invention
[0004] In view of this, this application provides an insulated decorative panel exterior wall system. This system changes the traditional installation method of insulated decorative panel exterior wall systems, which mainly relies on adhesive mortar bonding and secondarily on anchor fasteners. It creatively proposes a new installation method that emphasizes both anchor fasteners and adhesive bonding. This double-insurance design avoids detachment accidents caused by incomplete or ineffective mortar bonding, greatly improving the system's application safety. Furthermore, the system's panel joints utilize a double-layer waterproof structure, significantly enhancing its waterproof performance. The intermittent caulking design at the bottom of the snap-fit not only ensures the insulated decorative panel and the fasteners form a unified whole but also provides waterproofing and ventilation functions, ensuring effective drainage of moisture from within the wall. This solves the condensation problem inside the insulated decorative panel system and within the room, improving living comfort. The snap-fit is a single-piece structure, ensuring straight, uniform, and consistent width joints, improving the aesthetic appeal.
[0005] To achieve the above objectives, this application employs the following technical solution:
[0006] A thermal insulation decorative panel exterior wall system, characterized in that it includes a base layer, thermal insulation decorative panels, and two or more fixing fastener assemblies; the fixing fastener assembly includes an L-shaped load-bearing member fixedly installed on the base layer and a snap fastener fixedly installed on the L-shaped load-bearing member, the snap fastener including a second connecting plate, a first snap fastener and a second snap fastener, the first snap fastener and the second snap fastener being located at the front end of the second connecting plate, the first snap fastener protruding downwards, the second snap fastener protruding upwards, and the second snap fastener being located behind the first snap fastener; the lower end of the decorative panel of the thermal insulation decorative panel is provided with a downward and forward-opening side groove; the first snap fastener is pressed against the upper outer side wall of the decorative panel of the lower thermal insulation decorative panel, the second snap fastener is pressed against the vertical side wall of the side groove of the upper thermal insulation decorative panel, and the upper and lower fixing fastener assemblies can clamp the thermal insulation decorative panel; the side groove is also filled with a first sealing layer, and the thermal insulation decorative panel is also bonded to the base layer by an adhesive material.
[0007] Thermal insulation decorative panels consist of a decorative panel and an insulation layer. The decorative panel can be made of artificial inorganic boards with a decorative surface, or it can be metal, ceramic, natural stone, etc. The insulation material can be organic or inorganic. The decorative panel and the insulation material are bonded together with a high-strength adhesive. Some thermal insulation decorative panels also have a back panel. The decorative panel and back panel are rigid materials and are relatively heavy, while the insulation material is a flexible material and is relatively lightweight. Generally, the decorative panel is thicker than the back panel and is therefore heavier.
[0008] The base layer can be a newly built concrete wall, a masonry wall, or an old wall with a decorative finish.
[0009] The aforementioned thermal insulation decorative panel exterior wall system only requires milling a groove on one side of the thermal insulation decorative panel to form a side groove, simplifying the process. The fastener is a single strip with an effective anchoring length equal to the panel edge and an effective anchoring depth of 4mm to 6mm, maximizing the contact area with the panel. Compared to traditional slotted anchoring and milled edge anchoring methods, this effectively improves anchoring strength and preserves the thickness of the thermal insulation decorative panel to the maximum extent, ensuring anchoring firmness. Furthermore, the first and second fastening parts of the fastener in this application are designed with a staggered front-to-back alignment. The second fastening part is fitted inside the side groove, preventing vertical upward gaps that could cause system leakage. The first sealing layer further ensures the system's waterproof safety.
[0010] In some embodiments, the fastener is further fixedly provided with a first vertical fastener located behind the second fastener portion. The first vertical fastener extends upward and protrudes into the insulation layer of the upper insulation decorative panel, which is tightly attached to the inner side of the decorative panel. The second fastener portion, the first vertical fastener, and the second connecting plate form an upper U-shaped structure, which locks the lower end of the decorative panel. The width of the U-shaped groove matches the thickness of the lower opening of the decorative panel with the side groove, which can firmly lock the decorative panel, preventing the decorative panel from shifting and causing the waterproof sealant between the decorative panel and the fastener to peel off, resulting in a risk of water leakage. In addition, it can also improve the flatness of the wall surface, enhance the overall decorative effect of the exterior wall, and also lock the panel to prevent it from falling off.
[0011] In some embodiments, the L-shaped load-bearing component includes a vertical connector that fits into the base layer and a load-bearing plate integrally connected to and perpendicular to the vertical connector. The vertical connector is fixedly connected to the base layer through a first fixing connector. The front end of the load-bearing plate is provided with a downward-sloping first connecting plate. The second connecting plate is fastened to the first connecting plate and fixedly connected to it through a second fixing connector. The upper surface of the second connecting plate is flush with the upper surface of the load-bearing plate.
[0012] The second connecting plate, the first connecting plate, and the load-bearing plate work together to support the bottom of the upper insulation and decorative panel. Placing the upper surface of the second connecting plate flush with the upper surface of the load-bearing plate ensures even stress distribution. The second and first connecting plates can be offset by a certain distance, allowing insulation and decorative panels of different thicknesses within a certain range to be installed using the same fixing fastener assembly. This effectively saves production costs and solves the problem of varying distances between the wall and the decorative panel caused by uneven wall surfaces. The second and first connecting plates are directly anchored and locked together using fixing connectors to prevent displacement.
[0013] In some embodiments, the fastener is further fixedly provided with a limiting fixing block for abutting against the decorative panel above the lower insulation decorative panel, the lower surface of the limiting fixing block being flush with the lower surface of the load-bearing plate; the cross-sectional width of the limiting fixing block is not greater than the thickness of the decorative panel.
[0014] When there is a certain misalignment between the second connecting plate and the first connecting plate, the front end of the second connecting plate will be suspended between itself and the lower insulation decorative panel. Due to the greater weight of the upper insulation decorative panel, its center of gravity will be biased towards the decorative panel. When the gap is large, during construction and installation, the upper insulation decorative panel will bend downwards under pressure due to torque and its own weight. This can cause the upper insulation decorative panel to tilt forward, affecting the flatness of the installation, or the lower part of the decorative panel to be overhanging, posing a risk of sagging. The aforementioned limiting and fixing block is located above the decorative panel of the lower insulation decorative panel and has the same thickness as the first connecting plate. This ensures that the front, middle, and rear of the fixing fastener assembly have a consistent thickness. The weight of the upper insulation decorative panel will be evenly transferred to the lower insulation decorative panel through the combination of the second connecting plate + limiting and fixing block, the second connecting plate + first connecting plate, and the load-bearing plate, thereby ensuring uniform stress on the entire insulation decorative panel system and improving the overall stability and safety of the system's anchoring.
[0015] The cross-section of the limiting and fixing block can be square, inverted T-shaped, or hollow. Using an inverted T-shaped or hollow block can reduce material usage and save costs.
[0016] In some embodiments, the upper surface of the first connecting plate is a first roughened surface, and the lower surface of the second connecting plate is a second roughened surface; the first and second roughened surfaces are toothed or abrasive; the cross-sectional widths of the first and second connecting plates are the same. The roughened surface structure increases the friction at the connection points, ensuring a stronger connection between the fastener and the L-shaped load-bearing component. The consistent cross-sectional widths of the first and second connecting plates maximize the misalignment distance, saving material.
[0017] In some embodiments, a second sealing layer is provided at the seam between the second snap-fit part and the thermal insulation decorative panel. The second sealing layer is also provided on the inner side of the second snap-fit part, employing a double waterproof sealing structure to further enhance the waterproof safety of the entire system. Both the first and second sealing layers can be made of silicone sealant. The second sealing layer can also be located within the upper U-shaped groove formed by the second snap-fit part, the first vertical fixing member, and the second connecting plate, making construction and installation more convenient and faster.
[0018] In some implementations, sealing material is intermittently applied at the contact points between the first snap-fit part and the insulation decorative panel, and between the limiting fixing block and the insulation decorative panel. The sealing material used has excellent adhesion properties, allowing the snap-fit parts to be seamlessly connected to the lower insulation decorative panel, thus improving the overall system's safety. Areas without sealing material can form waterproof ventilation channels, ensuring effective drainage of moisture from within the wall, solving the condensation problem inside the insulation decorative panel system and within the room, and improving living comfort.
[0019] In some embodiments, the first fixing member is a fixing anchor, and the second fixing member is a screw. The fixing anchor can be an expansion bolt, chemical anchor, knotted anchor, etc., and the screw should preferably be a self-tapping screw made of stainless steel or galvanized iron.
[0020] The bonding material can be mortar-based adhesive, organic adhesive, etc.
[0021] In some embodiments, the buckle is further fixedly provided with a second vertical fixing member located behind the first buckle portion. The second vertical fixing member extends downward and protrudes into the insulation layer of the lower insulation decorative panel, which is close to the inner side of the decorative panel. The first buckle portion and the second vertical fixing member form a downward U-shaped structure, which clamps the upper end of the decorative panel. The upper and lower fixing buckle assemblies can clamp the decorative panel of the insulation decorative panel through the upper U-shaped structure and the lower U-shaped structure.
[0022] The insulation layer of thermally insulated decorative panels is usually made of organic or inorganic materials. Organic materials have a B1 fire rating, which means they may burn away in a fire, leaving a hollow space between the outer decorative panel and the base layer. The upper and lower U-shaped structures in this application can stably clamp the decorative panel from both ends, preventing it from falling and causing a safety accident.
[0023] In some embodiments, the L-shaped load-bearing component and the fastener are integrally formed, the L-shaped load-bearing component is a continuous structure or an intermittent structure, and the fastener is a continuous structure.
[0024] Its one-piece molding ensures accurate material precision, convenient processing, and stable strength. The continuous structure of the fastener significantly increases the anchoring force on the insulated decorative panel. Single-point anchoring force tests conducted by a national testing institution show that, using an 8mm decorative panel, the single-point anchoring force of the slotted anchor is 250N–400N, the single-point anchoring force of the milled edge anchor is 500N–700N, and the single-point anchoring force of the fixing fastener assembly described in this solution is 1000N–1500N. The continuous L-shaped load-bearing component improves the support capacity for the insulated decorative panel, making it suitable for heavy-duty insulated decorative panel systems or coastal typhoon areas, thus improving system application safety. The intermittent L-shaped load-bearing component saves material and reduces costs.
[0025] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:
[0026] This application discloses an insulated decorative panel exterior wall system. It only requires milling a groove on one side of the insulated decorative panel to form a side groove, maximizing the contact area between the fastener and the panel. Compared to traditional point anchoring methods such as slotted anchoring and milled edge anchoring, this improves anchoring strength and enhances the safety performance of the insulated decorative panel system. Furthermore, it preserves the thickness of the insulated decorative panel to the maximum extent, ensuring the firmness of the anchoring. In addition, the first and second fastening parts of the fastener in this application are designed with a staggered front-to-back alignment. The second fastening part is fitted inside the side, preventing vertical upward gaps that could cause system leakage. The first sealing layer further ensures the system's waterproof safety.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.
[0033] See Figures 1 to 3 An exterior wall system with an insulated decorative panel 2 includes a base layer 1, an insulated decorative panel 2, and two or more fixing fastener assemblies. Each fixing fastener assembly includes an L-shaped load-bearing member 3 fixedly installed on the base layer 1 and a fastener 4 fixedly installed on the L-shaped load-bearing member 3. The fastener 4 includes a second connecting plate 44, a first fastening part 41, and a second fastening part 42. The first fastening part 41 and the second fastening part 42 are located at the front end of the second connecting plate 44. The first fastening part 41 protrudes downwards, and the second fastening part 42 protrudes upwards. 2 is located behind the first buckle part 41; the lower end of the decorative panel 21 of the thermal insulation decorative panel 2 is provided with a downward and forward-opening side groove 23; the first buckle part 41 is fastened to the upper outer wall of the decorative panel 21 of the lower thermal insulation decorative panel 2, and the second buckle part 42 is fastened to the vertical side wall of the side groove 23 of the upper thermal insulation decorative panel 2. The upper and lower fixing buckle components can clamp the thermal insulation decorative panel 2; the side groove 23 is also filled with a first sealing layer 5, and the thermal insulation decorative panel 2 and the base layer 1 are also bonded together by an adhesive material 6.
[0034] The thermal insulation decorative panel 2 includes a decorative panel 21 and an insulation layer 22. The decorative panel 21 can be made of artificial inorganic board with a decorative surface, or it can be a metal plate, ceramic plate, natural stone, etc. The insulation material can be an organic insulation material or an inorganic insulation material. The decorative panel 21 and the insulation material are bonded together with a high-strength adhesive. Some other thermal insulation decorative panels 2 also have a back panel. The decorative panel 21 and the back panel are rigid materials and are relatively heavy, while the insulation material is a soft material and is relatively light. Generally, the decorative panel 21 is thicker than the back panel and is heavier.
[0035] Base layer 1 can be a newly built concrete wall, a masonry wall, or an old wall with a decorative finish, etc.
[0036] This thermal insulation decorative panel 2 exterior wall system only requires milling a groove 23 on one side of the thermal insulation decorative panel 2 material, simplifying the process. The fastener 4 is a single strip, with an effective anchoring length the same as the panel edge and an effective anchoring depth of 4mm to 6mm, maximizing the contact area with the panel. Compared to traditional grooved anchoring and milled edge anchoring methods, this effectively improves anchoring strength and preserves the thickness of the thermal insulation decorative panel 2 to the maximum extent, ensuring anchoring firmness. In addition, the first fastening part 41 and the second fastening part 42 of the fastener 4 in this application adopt a staggered design, with the second fastening part 42 snapped inside the side groove 23, preventing vertical upward gaps that could cause system leakage. Furthermore, the first sealing layer 5 ensures the waterproof safety of the system.
[0037] The fastener 4 is also fixedly provided with a first vertical fastener 43 located behind the second fastener part 42. The first vertical fastener 43 extends upward and protrudes into the insulation layer 22 inside the upper insulation decorative panel 2, which is close to the inside of the decorative panel 21. The second fastener part 42, the first vertical fastener 43, and the second connecting plate 44 form an upper U-shaped structure, which locks the lower end of the decorative panel 21. The width of the U-shaped groove matches the thickness of the lower opening of the decorative panel 21 with the side groove 23, which can firmly lock the decorative panel 21 and prevent the decorative panel 21 from shifting and causing the waterproof sealant between the decorative panel 21 and the fastener 4 to peel off, resulting in a water leakage risk. In addition, it can also improve the flatness of the wall surface, enhance the overall decorative effect of the exterior wall, and lock the panel to prevent it from falling off.
[0038] The L-shaped load-bearing component 3 includes a vertical connector 31 that fits into the base layer 1 and a load-bearing plate 32 integrally connected to and perpendicular to the vertical connector 31. The vertical connector 31 is fixedly connected to the base layer 1 through a first fixed connector 9. A downward-sloping first connecting plate 33 is provided at the front end of the load-bearing plate 32. A second connecting plate 44 is fastened to the first connecting plate 33 and fixedly connected through a second fixed connector 10. The upper surface of the second connecting plate 44 is flush with the upper surface of the load-bearing plate 32.
[0039] The second connecting plate 44, the first connecting plate 33, and the load-bearing plate 32 work together to support the bottom of the upper insulation decorative panel 2. Placing the upper surface of the second connecting plate 44 flush with the upper surface of the load-bearing plate 32 ensures even stress distribution. The second connecting plate 44 and the first connecting plate 33 can be staggered by a certain distance, ensuring that insulation decorative panels 2 of different thicknesses within a certain range can be installed using the same fixing fastener assembly. This effectively saves production costs and solves the problem of varying distances between the wall and the decorative panel 21 caused by uneven wall surfaces. The second connecting plate 44 and the first connecting plate 33 are directly anchored and locked using fixing connectors to prevent displacement of the second connecting plate 44 and the first connecting plate 33.
[0040] The fastener 4 is also fixedly provided with a limiting fixing block 45 for abutting against the decorative panel 21 of the lower insulation decorative board 2. The lower surface of the limiting fixing block 45 is flush with the lower surface of the load-bearing plate 32. The cross-sectional width of the limiting fixing block 45 is not greater than the thickness of the decorative panel 21.
[0041] When there is a certain misalignment between the second connecting plate 44 and the first connecting plate 33, the front end of the second connecting plate 44 will be suspended from the lower insulation decorative panel 2. Due to the large weight of the upper insulation decorative panel 2, its center of gravity will be biased towards the decorative panel 21. When the gap is large, during the construction and installation process, the upper insulation decorative panel 2 will be subjected to torque and its own weight, causing the front end of the second connecting plate 44 to be compressed and bent downwards. This may result in the upper insulation decorative panel 2 tilting forward, affecting the flatness of the installation, or the lower part of the decorative panel 21 being overhanging, posing a risk of falling. The aforementioned limiting and fixing block 45 is located above the decorative panel 21 of the lower insulation and decorative panel 2, and its thickness is the same as that of the first connecting plate 33. In this way, the front, middle and rear of the fixing buckle assembly maintain the same thickness. The weight of the upper insulation and decorative panel 2 will be evenly transferred to the lower insulation and decorative panel 2 through the combination of the second connecting plate 44 + limiting and fixing block 45, the second connecting plate 44 + first connecting plate 33 and load-bearing plate 32, thereby ensuring that the entire insulation and decorative panel 2 system is subjected to uniform force and improving the stability and safety of the overall anchoring of the system.
[0042] The cross-section of the limiting and fixing block 45 can be square, inverted T-shaped, or hollow. Using an inverted T-shaped or hollow block can reduce material usage and save costs.
[0043] The upper surface of the first connecting plate 33 is a first roughened surface 331, and the lower surface of the second connecting plate 44 is a second roughened surface 441. Both the first roughened surface 331 and the second roughened surface 441 are toothed or abrasive. The cross-sectional widths of the first connecting plate 33 and the second connecting plate 44 are the same. The roughened surface structure increases the friction at the connection point, ensuring a stronger connection between the fastener 4 and the L-shaped load-bearing component 3. The consistent cross-sectional widths of the first connecting plate 33 and the second connecting plate 44 maximize the misalignment distance and save material.
[0044] A second sealing layer 7 is provided at the seam between the second snap-fit part 42 and the thermal insulation decorative panel 2. The second sealing layer 7 is also provided on the inner side of the second snap-fit part 42, employing a double waterproof sealing structure to further enhance the waterproof safety of the entire system. The first sealing layer 5 and the second sealing layer 7 can be made of silicone sealant. The second sealing layer 7 can also be located within the upper U-shaped groove formed by the second snap-fit part 42, the first vertical fixing member 43, and the second connecting plate 44, making construction and installation more convenient and faster.
[0045] Sealing material is intermittently applied at the contact points between the first snap-fit part 41 and the thermal insulation decorative panel 2, and between the limiting fixing block 45 and the thermal insulation decorative panel 2. The sealing material used has excellent adhesion properties, allowing the snap-fit part 4 to be seamlessly connected to the lower thermal insulation decorative panel 2, thus improving the overall system's safety. Areas without sealing material form waterproof ventilation channels, ensuring effective drainage of moisture from the wall, solving the condensation problem inside the thermal insulation decorative panel 2 system and within the room, and improving living comfort.
[0046] The first fixing connector 9 is a fixing anchor, and the second fixing connector 10 is a screw. The fixing anchor can be an expansion bolt, chemical anchor, knotted anchor, etc., and the screw should preferably be a self-tapping screw made of stainless steel or galvanized iron.
[0047] The bonding material 6 can be a mortar-type adhesive, an organic adhesive, etc.
[0048] Both the L-shaped load-bearing component 3 and the fastener 4 are integrally formed. The L-shaped load-bearing component 3 is either a continuous or intermittent structure, while the fastener 4 is a continuous structure.
[0049] Its one-piece molding ensures accurate material precision, convenient processing, and stable strength. The continuous structure of the fastener 4 significantly increases the anchoring force on the insulation decorative panel 2. Single-point anchoring force tests conducted by a national testing institution show that, using an 8mm decorative panel 21, the single-point anchoring force for slotted anchors is 250N–400N, and for milled edge anchors it is 500N–700N. The single-point anchoring force of the fixing fastener assembly in this solution is 1000N–1500N. The continuous structure of the L-shaped load-bearing component 3 enhances the support force on the insulation decorative panel 2, making it suitable for heavier insulation decorative panel 2 systems or coastal typhoon areas, thus improving system safety. The intermittent structure of the L-shaped load-bearing component 3 saves material and reduces costs.
[0050] See Figure 4 This illustrates another embodiment of the present application, which differs from the above embodiment in that: in some embodiments, a second vertical fixing member 46 is also fixedly provided on the buckle 4 behind the first buckle part 41. The second vertical fixing member 46 extends downward and protrudes and is inserted into the insulation layer 22 of the lower insulation decorative panel 2, which is close to the inner side of the decorative panel 21. The first buckle part 41 and the second vertical fixing member 46 form a downward U-shaped structure, which clamps the upper end of the decorative panel 21. The upper and lower fixing buckle assemblies can clamp the decorative panel 21 of the insulation decorative panel 2 through the upper U-shaped structure and the lower U-shaped structure.
[0051] The insulation layer 22 of the insulated decorative panel 2 is usually made of organic or inorganic materials. Organic materials have a B1 fire rating and may burn away in a fire, resulting in a hollow space between the outer decorative panel 21 and the base layer 1. The upper and lower U-shaped structures in this application can stably clamp the decorative panel 21 from both above and below, preventing the decorative panel 21 from falling and causing a safety accident.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
