Description

Technical Field

[0001] The present application relates to an exterior wall system, in particular to an exterior wall system of thermal insulation decorative panels. Background Art

[0002] Insulated decorative composite panels are a new green building material that combines decoration and energy conservation, and are widely used in building exterior wall insulation. Traditional thermal insulation decorative panels are typically installed primarily with adhesive mortar, supplemented by anchors. Traditional anchoring methods for thermal insulation decorative panels include slotted insert anchors and milled edge clip anchors. Slotted insert anchors have an effective anchoring width of approximately 20mm to 30mm and a limited anchoring depth of approximately 3mm to 10mm. Milled edge clip anchors have an effective anchoring width of approximately 30mm to 50mm and an effective anchoring depth of approximately 2mm to 4mm. Slotted anchors require slotting on at least two opposite sides of the plate. After slotting, the thickness of the plate at the anchoring force-bearing part is less than half of the thickness of the original plate. In addition, in order to prevent the finishing layer at the slotted part from collapsing, the slot center will be offset to the insulation layer side, resulting in the plate thickness at the anchoring force-bearing part being less than 1 / 3 of the original plate thickness. In addition, for ease of installation, the installers will open the slot very wide. Affected by the slot position and the effective anchoring area, the anchoring strength of this slotted anchor is very low, and may even fail to meet the minimum anchoring force requirements specified in the standard. Milling edge anchors require milling the upper and lower opposite sides of the plate, and the process is cumbersome. In addition, due to the influence of processing size deviation, wall deviation and other aspects at the construction site, the problem of virtual anchoring of the anchor often occurs, thus causing safety hazards.

[0003] Traditionally, insulation decorative panel systems use point anchoring, with anchors installed in the panel seams and distributed in a dotted pattern, typically with 6 to 8 anchors per square meter. This method offers limited anchoring force and limited holding power for the insulation decorative panels. In extreme situations, such as when the bonding mortar becomes loose, fails, or a fire completely destroys the insulation layer, this anchoring method can no longer effectively secure the panels, causing them to fall off the wall or fall off the wall in a fire, posing a significant threat to property and personal safety. Summary of the Invention

[0004] In view of this, the present application provides an insulation decorative panel exterior wall system. This system changes the traditional installation method of insulation decorative panel exterior wall systems, which mainly relies on bonding mortar and supplemented by anchoring with anchors. It creatively proposes a new installation method that emphasizes both anchoring with anchors and bonding with adhesives. This double-safety design can avoid detachment accidents caused by mortar adhesion or failure, greatly improving the application safety of the system. In addition, the system's panel seams are equipped with two waterproof structures, greatly improving the system's waterproof performance. The lower end of the bayonet is designed with intermittent gluing, which not only ensures that the insulation decorative panel and the fixing fastener are integrated, but also provides a waterproof exhaust function, ensuring that moisture in the wall can be effectively discharged, solving the problem of condensation inside the insulation decorative panel system and indoors, and improving living comfort. The bayonet is a single-piece structure, ensuring that the panel seams are straight, uniform, and of uniform width, improving the decorative aesthetics.

[0005] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0006] 18. The thermal insulation decorative panel exterior wall system of claim 17, wherein the fixing buckle assembly comprises an L-shaped load-bearing member fixedly mounted on the base layer and a clip fixedly mounted on the L-shaped load-bearing member, the clip comprising a second connecting plate, a first clip portion and a second clip portion, the first clip portion and the second clip portion being located at a front end of the second connecting plate, the first clip portion protruding downward, the second clip portion protruding upward, and the second clip portion being located behind the first clip portion; a side groove opening downward and forward is provided at the lower end of the decorative panel of the thermal insulation decorative panel; the first clip portion is buckled on the upper outer wall of the decorative panel of the lower thermal insulation decorative panel, the second clip portion is buckled on the vertical side wall of the side groove of the upper thermal insulation decorative panel, and the upper and lower layers of fixing buckle assemblies can clamp the thermal insulation decorative panels; the side groove is also filled with a first sealing layer, and the thermal insulation decorative panels and the base layer are bonded by an adhesive material.

[0007] Insulation decorative panels consist of a decorative panel and an insulation layer. The decorative panel can be made of a man-made inorganic sheet with a decorative surface, metal, ceramic, or natural stone. The insulation material can be organic or inorganic, and the decorative panel and insulation material are bonded with a high-strength adhesive. Some other insulation decorative panels also have a backing plate. The decorative panel and backing plate are made of hard materials and are heavier, while the insulation material is made of soft materials and is lighter. Generally, the decorative panel is thicker and heavier than the backing plate.

[0008] The base layer can be a new concrete wall, a masonry wall, an old wall with a decorative surface, etc.

[0009] The above-mentioned insulation decorative panel exterior wall system of the present application only requires milling a groove on one side of the insulation decorative panel to form a side groove. The process is simple, the clip is a whole strip, the effective anchoring length is the same length as the panel edge, and the effective anchoring depth is 4mm to 6mm. The contact area with the panel can be maximized. Compared with the traditional slotted anchoring and milled edge anchoring methods, it can effectively improve the anchoring strength; and it also retains the thickness of the insulation decorative panel to the greatest extent, ensuring the firmness of the anchoring. In addition, the first clip part and the second clip part of the clip in the present application adopt a front-to-back staggered design. The second clip part is clamped inside the side groove to avoid vertical upward seams that cause system leakage, and the first sealing layer ensures the waterproof safety of the system.

[0010] In some embodiments, the clip is further fixedly provided with a first vertical fixing member located behind the second clip portion. The first vertical fixing member extends upward and protrudes and is inserted into the insulation layer of the upper insulation decorative plate, which is close to the inner side of the decorative panel. The second clip portion, the first vertical fixing member, and the second connecting plate form an upper U-shaped structure that clamps the lower end of the decorative panel. The width of the above-mentioned U-shaped groove matches the thickness of the lower end of the decorative panel with the side groove, which can firmly clamp the decorative panel, preventing the decorative panel from shifting and causing the waterproof sealing material between the decorative panel and the clip to peel off, causing a potential water leakage. In addition, it can also improve the flatness of the wall surface, enhance the decorative effect of the entire exterior wall, and also clamp the panel to prevent it from falling off.

[0011] In some embodiments, the L-shaped load-bearing member includes a vertical connecting member that is in contact with the base layer and a load-bearing plate that is integrally connected to the vertical connecting member and perpendicular to the base layer. The vertical connecting member is fixedly connected to the base layer through a first fixed connecting member, and a first connecting plate that sinks downward is provided at the front end of the load-bearing plate; the second connecting plate is buckled on the first connecting plate and fixedly connected through a second fixed connecting member, and the upper surface of the second connecting plate is flush with the upper surface of the load-bearing plate.

[0012] The second connecting plate, first connecting plate, and load-bearing plate collectively support the bottom of the upper insulation decorative panel. Aligning the upper surface of the second connecting plate with the upper surface of the load-bearing plate ensures uniform force distribution. The second connecting plate and the first connecting plate can be offset by a certain distance. This ensures that insulation decorative panels of varying thicknesses within a certain range can be installed using the same fixing buckle assembly, effectively reducing production costs and addressing the issue of varying distances between the wall and the decorative panel caused by uneven wall surfaces. The second connecting plate and the first connecting plate are directly anchored and locked together via fixed connectors, preventing displacement of the second and first connecting plates.

[0013] In some embodiments, the snap fastener is also fixed with a limiting fixing block for supporting the decorative panel above the lower insulation decorative panel, and the lower surface of the limiting fixing block is 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 distance between the second connecting plate and the first connecting plate, there will be a gap between the front end of the second connecting plate and the lower insulation decorative plate. The center of gravity of the upper insulation decorative plate will be biased towards the decorative panel due to the heavy weight of the panel. When the gap width is large, during the construction and installation process, the upper insulation decorative plate will be compressed by the torque and its own weight, causing the front end of the second connecting plate to bend downward, resulting in the upper insulation decorative plate tilting forward, affecting the installation flatness, or the lower part of the decorative panel cantilevering and posing a risk of falling. The above-mentioned limiting fixing block is located above the decorative panel of the lower insulation decorative plate, and its thickness is consistent with that of the first connecting plate. In this way, the front, middle and rear thicknesses of the fixing buckle assembly are consistent, and the weight of the upper insulation decorative plate will be evenly transferred to the lower insulation decorative plate through the combination of the second connecting plate + limiting fixing block, the second connecting plate + the first connecting plate, and the load-bearing plate, thereby ensuring that the entire insulation decorative panel system is evenly stressed and improving the stability and safety of the overall anchoring of the system.

[0015] The cross section of the limiting fixing block can be square, inverted T-shaped, or hollow. When the inverted T-shaped or hollow shape is adopted, the material consumption can be reduced and the cost can be saved.

[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 serrated or frosted. The cross-sectional widths of the first and second connecting plates are identical. The roughened surface structure increases friction at the connection point, ensuring a stronger connection between the clip and the L-shaped load-bearing member. The identical cross-sectional widths of the first and second connecting plates maximize the maximum distance of misalignment and conserve materials.

[0017] In some embodiments, a second sealing layer is provided at the gap between the second snap portion and the thermal insulation decorative panel. A second sealing layer is also provided inside the second snap portion, creating a double waterproof seal, further enhancing the waterproof security of the entire system. Silicone sealant can be used for the first and second sealing layers. The second sealing layer can also be provided within the upper U-shaped structural groove formed by the second snap portion, the first vertical fixing member, and the second connecting plate, making installation more convenient and quicker.

[0018] In some embodiments, sealing material is intermittently applied at the points of contact between the first clip and the insulation decorative panel, and between the retaining block and the insulation decorative panel. This sealing material exhibits excellent bonding properties, and the areas where it is applied seamlessly connect the front end of the clip to the underlying insulation decorative panel, enhancing the safety of the entire system. Areas where sealing material is not applied form waterproof vents, ensuring the effective discharge of moisture from the wall. This eliminates condensation within the insulation decorative panel system and indoors, improving living comfort.

[0019] In some embodiments, the first fixing member is a fixing anchor bolt, and the second fixing member is a screw. The fixing anchor bolt can be an expansion bolt, a chemical bolt, a knotted anchor bolt, etc., and the screw is preferably a self-tapping screw made of stainless steel or galvanized iron.

[0020] The bonding material can be a mortar-type adhesive, an organic glue-type adhesive, etc.

[0021] In some embodiments, the fastener is also fixed with a second vertical fixing member located behind the first fastening portion, and the second vertical fixing member extends downward and protrudes and is inserted into the insulation layer of the lower insulation decorative plate close to the inner side of the decorative panel. The first fastening 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 layers of the fixing buckle assembly can clamp the decorative panel of the insulation decorative plate through the upper U-shaped structure and the lower U-shaped structure.

[0022] The insulation layer of thermal insulation decorative panels is typically made of organic or inorganic materials. Organic materials have a combustion performance rating of B1 and may burn away in a fire, resulting in 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 above and below, preventing it from falling and causing safety accidents.

[0023] In some embodiments, the L-shaped load-bearing member and the snap fastener are both integrally formed, the L-shaped load-bearing member is a full-length structure or a discontinuous structure, and the snap fastener is a full-length structure.

[0024] Its one-piece molding can ensure accurate material precision, easy processing, and stable strength. The clip is a full-length structure, which can multiply the anchoring force of the insulation decorative panel. The single-point anchoring force test conducted by the national testing agency shows that for 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 fixed buckle assembly described in this solution is 1000N~1500N. The full-length structure of the L-shaped load-bearing component can improve the supporting force of the insulation decorative panel. It is suitable for heavier insulation decorative panel systems or coastal typhoon areas, improving the safety of system application. The discontinuous structure of the L-shaped load-bearing component can save material usage and reduce costs.

[0025] It can be seen from the above technical solution that this application has at least the following advantages and positive effects:

[0026] This application discloses an insulation decorative panel exterior wall system that only requires milling a groove on one side of the insulation decorative panel to form a side groove. This maximizes the contact area between the fastener and the panel, improving anchoring strength compared to traditional point anchoring methods such as slotted anchors and milled edge anchors. This improves the safety of the insulation decorative panel system and maximizes the thickness of the insulation decorative panel, ensuring anchoring security. Furthermore, the first and second clipping parts of the clip in this application are designed with a front-to-back offset, with the second clipping part mounted inside the side, preventing vertical upward seams from causing system leakage. Furthermore, the first sealing layer ensures the waterproof safety of the system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The terms used in the implementation methods of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0033] See also Figures 1 to 3 , an insulation decorative panel 2 exterior wall system, comprising a base layer 1, an insulation decorative panel 2 and two or more fixing buckle assemblies; the fixing buckle assembly comprises an L-shaped load-bearing member 3 fixedly mounted on the base layer 1 and a fastener 4 fixedly mounted on the L-shaped load-bearing member 3, the fastener 4 comprises a second connecting plate 44, a first fastener portion 41 and a second fastener portion 42, the first fastener portion 41 and the second fastener portion 42 are located at the front end of the second connecting plate 44, the first fastener portion 41 protrudes downward, the second fastener portion 42 protrudes upward, and the second fastener portion 4 2 is located behind the first buckle portion 41; the lower end of the decorative panel 21 of the thermal insulation decorative board 2 is provided with a side groove 23 open downward and forward; the first buckle portion 41 is buckled on the upper end outer wall of the decorative panel 21 of the lower thermal insulation decorative board 2, and the second buckle portion 42 is buckled on the vertical side wall of the side groove 23 of the upper thermal insulation decorative board 2, and the upper and lower layers of the fixing buckle assembly can clamp the thermal insulation decorative board 2; the side groove 23 is also filled with a first sealing layer 5, and the thermal insulation decorative board 2 and the base layer 1 are also bonded 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 a man-made inorganic sheet with a decorative surface, a metal plate, a ceramic plate, or natural stone. The insulation material can be organic or inorganic. The decorative panel 21 and the insulation material are bonded together using a high-strength adhesive. Some other thermal insulation decorative panels 2 also have a backboard. The decorative panel 21 and backboard are made of hard materials and are relatively heavy, while the insulation material is made of soft materials and is relatively light. Generally, the decorative panel 21 is thicker than the backboard and is therefore heavier.

[0035] The base layer 1 can be a newly built concrete wall, a masonry wall, an old wall with a decorative surface, etc.

[0036] The exterior wall system of the thermal insulation decorative panel 2 only requires milling a groove on one side of the thermal insulation decorative panel 2 to form a side groove 23. The process is simple, the clip 4 is a whole strip, the effective anchoring length is the same length as the panel edge, and the effective anchoring depth is 4mm to 6mm. The contact area with the panel can be maximized. Compared with the traditional slotted anchoring and milled edge anchoring methods, it can effectively improve the anchoring strength; and it also retains the thickness of the thermal insulation decorative panel 2 to the greatest extent, ensuring the firmness of the anchoring. In addition, the first clip part 41 and the second clip part 42 of the clip 4 in this application adopt a front-to-back staggered design. The second clip part 42 is clamped inside the side groove 23 to avoid vertical upward seams that cause system leakage, and the first sealing layer 5 ensures the waterproof safety of the system.

[0037] The clip 4 is also fixedly provided with a first vertical fixing member 43 located behind the second fixing portion 42. The first vertical fixing member 43 extends upward and is inserted into the insulation layer 22 of the upper insulation decorative board 2, which is close to the inner side of the decorative panel 21. The second fixing portion 42, the first vertical fixing member 43, and the second connecting plate 44 form an upper U-shaped structure that clamps the lower end of the decorative panel 21. The width of the U-shaped groove matches the thickness of the lower end of the decorative panel 21 with the side groove 23. This can firmly clamp the decorative panel 21, preventing the decorative panel 21 from shifting and causing the waterproof sealing material between the decorative panel 21 and the clip 4 to peel off, causing a potential water leakage. It also improves the wall surface flatness, enhances the decorative effect of the entire exterior wall, and can also clamp the panel to prevent it from falling off.

[0038] The L-shaped load-bearing member 3 includes a vertical connecting member 31 that fits with the base layer 1 and a load-bearing plate 32 that is integrally connected to the vertical connecting member 31 and perpendicular to it. The vertical connecting member 31 is fixedly connected to the base layer 1 through a first fixed connecting member 9. A first connecting plate 33 that sinks downward is provided at the front end of the load-bearing plate 32; the second connecting plate 44 is buckled on the first connecting plate 33 and fixedly connected through the second fixed connecting member 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 bearing plate 32 collectively support the bottom of the upper insulating decorative panel 2. The upper surface of the second connecting plate 44 is flush with the upper surface of the bearing plate 32 to ensure uniform force distribution. The second connecting plate 44 and the first connecting plate 33 can be offset by a certain distance. This ensures that insulating decorative panels 2 of varying thicknesses within a certain range can be installed using the same fixing buckle assembly, effectively saving production costs and addressing the issue 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 together via fixed connectors, preventing them from shifting.

[0040] The clip 4 is also fixed with a limiting fixing block 45 for resting against the decorative panel 21 of the lower thermal insulation decorative panel 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 distance between the second connecting plate 44 and the first connecting plate 33, there will be a suspension between the front end of the second connecting plate 44 and the lower insulation decorative panel 2. The center of gravity of the upper insulation decorative panel 2 will be biased toward the decorative panel 21 due to the heavy weight of the panel. When the suspension width is large, during the construction and installation process, the upper insulation decorative panel 2 will be compressed and bent downward under the action of the torque and its own weight, causing the upper insulation decorative panel 2 to tilt forward and affect the installation flatness, or the lower part of the decorative panel 21 to be cantilevered and there is a risk of falling. The above-mentioned limiting fixing block 45 is located above the decorative panel 21 of the lower insulation decorative panel 2, and its thickness is consistent with the thickness of the first connecting plate 33. In this way, the front, middle and rear of the fixing buckle assembly maintain consistent thickness. The weight of the upper insulation decorative panel 2 will be evenly transferred to the lower insulation decorative panel 2 through the combination of the second connecting plate 44 + limiting fixing block 45, the second connecting plate 44 + the first connecting plate 33, and the load-bearing plate 32, thereby ensuring that the entire insulation decorative panel 2 system is evenly stressed and improving the stability and safety of the overall anchoring of the system.

[0042] The cross section of the position limiting fixing block 45 can be square, inverted T-shaped, or hollow. When the inverted T-shaped or hollow shape is adopted, the amount of material used can be reduced, thus saving 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 have a serrated or frosted finish. The cross-sectional widths of the first connecting plate 33 and the second connecting plate 44 are identical. The roughened surface increases friction at the connection, ensuring a stronger connection between the latch 4 and the L-shaped load-bearing member 3. The identical cross-sectional widths of the first connecting plate 33 and the second connecting plate 44 maximize the distance of misalignment and conserve material.

[0044] A second sealing layer 7 is positioned at the gap between the second snap portion 42 and the thermal insulation decorative panel 2. The second sealing layer 7 is also positioned inside the second snap portion 42, creating a double waterproof seal that further enhances the overall system's waterproof security. Silicone sealant can be used for the first and second sealing layers 5 and 7. The second sealing layer 7 can also be positioned within the upper U-shaped structural groove formed by the second snap portion 42, the first vertical fixing member 43, and the second connecting plate 44, making installation more convenient and quick.

[0045] Sealing material is intermittently applied at the points of contact between the first clip 41 and the insulation decorative panel 2, and between the stopper 45 and the insulation decorative panel 2. This sealing material exhibits excellent bonding properties. The areas where the sealing material is applied seamlessly connect the front end of the clip 4 to the underlying insulation decorative panel 2, enhancing the safety of the entire system. Areas where the sealing material is not applied form waterproof venting channels, ensuring that moisture within the wall can be effectively discharged. This eliminates condensation within the insulation decorative panel 2 system and indoors, improving living comfort.

[0046] The first fixing connector 9 is a fixing anchor bolt, and the second fixing connector 10 is a screw. The fixing anchor bolt can be an expansion bolt, a chemical bolt, a knotted anchor bolt, etc., and the screw is preferably a self-tapping screw made of stainless steel or galvanized iron.

[0047] The bonding material 6 can be a mortar-type bonding agent, an organic glue-type bonding agent, etc.

[0048] The L-shaped load-bearing member 3 and the snap-fit member 4 are both integrally formed. The L-shaped load-bearing member 3 is a full-length structure or a discontinuous structure, and the snap-fit member 4 is a full-length structure.

[0049] Its one-piece molding can ensure accurate material precision, easy processing and stable strength. The clip 4 is a full-length structure, which can multiply the anchoring force of the thermal insulation decorative panel 2. The single-point anchoring force test conducted by the national testing agency shows that when using an 8mm decorative panel 21, 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 fixed buckle assembly of this scheme is 1000N~1500N. The full-length structure of the L-shaped load-bearing component 3 can increase the supporting force of the thermal insulation decorative panel 2, and is suitable for heavier thermal insulation decorative panel 2 systems or coastal typhoon areas, thereby improving the safety of system application. The intermittent structure of the L-shaped load-bearing component 3 can save material usage and reduce costs.

[0050] See also Figure 4 , represents another embodiment of the present application, which differs from the above embodiment in that: in some embodiments, a second vertical fixing member 46 located behind the first fixing portion 41 is fixedly provided on the fastener 4, and 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 close to the inner side of the decorative panel 21. The first fixing portion 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 layers of the fixing buckle components 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 insulation decorative panel 2 is typically made of organic or inorganic materials. Organic materials have a combustion performance of B1 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 of the present application can stably clamp the decorative panel 21 from above and below, preventing the decorative panel 21 from falling and causing safety accidents.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them. Although the embodiments of the present application have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
