Abstract
Description
Technical Field
[0001] This utility model relates to the field of exterior wall composite panel technology, and in particular to an integrated exterior wall insulation and decoration composite panel. Background Technology
[0002] Exterior wall insulation and decoration integrated composite panels, also known as exterior wall insulation boards or composite exterior wall panels, are exterior wall insulation and decoration panels made by combining a coated and printed decorative panel with an insulation substrate. Compared to traditional building decorative surfaces, exterior wall insulation and decoration integrated composite panels add an insulation layer, reducing secondary construction costs, and are therefore widely used in the field of exterior wall decoration.
[0003] However, existing integrated exterior wall insulation and decoration composite panels often use two methods to handle the external corners of buildings: one is to use a chamfered corner method, such as... Figure 1 As shown, one method involves cutting 45-degree inner bevels along the opposite edges of two integrated exterior wall insulation and decorative composite panels at the external corner. The decorative panel 1', adhesive layer 2', and insulation board 3' are all ground or cut, and the inner bevels of the two panels are joined to form a right angle at the external corner. Another method uses an interlocking mechanism, where a section of insulation board 3' is removed from the edge of one panel, the width of which is equal to the thickness of the opposite panel. The exposed decorative panel 1' is then interlocked with the side wall of the other panel. Although both methods of treating external corners are widely used, they inevitably result in seams. Furthermore, the seams are only sealed with sealant on the outer side, leading to discontinuities in the insulation layer and creating thermal bridge defects at the seams, thus reducing thermal insulation performance.
[0004] Therefore, it is necessary to develop a new type of integrated composite panel for exterior wall insulation and decoration to address the above-mentioned shortcomings, which has become an urgent problem for those skilled in the art. Summary of the Invention
[0005] The purpose of this utility model is to provide an integrated composite panel for exterior wall insulation and decoration, which is applied to the external corner of a building and is seamlessly treated to ensure the integrity of the insulation layer at the external corner of the building.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This utility model discloses an integrated composite panel for exterior wall insulation and decoration, which is applied to the external corner of a building. It includes an external corner decorative panel and an external corner insulation panel. Both the external corner decorative panel and the external corner insulation panel are integrally formed right-angled shapes. The external corner insulation panel is bonded to the inner side wall of the external corner decorative panel through an adhesive layer.
[0008] Furthermore, the corner decorative panel is specifically made of ceramic, metal plate or fiber cement board.
[0009] Furthermore, the external corner insulation board is specifically made of polystyrene foam board, extruded polystyrene board, polyurethane foam board, or rock wool board.
[0010] Furthermore, a clearance groove is provided at the inner corner vertex of the external corner insulation board, and the clearance groove is an arc groove.
[0011] Furthermore, it also includes a corner support plate, which is bonded to the inner corner of the external corner decorative panel by the second adhesive layer. The corner support plate is embedded in the external corner insulation board, and the external corner insulation board has a recessed groove in the corner support plate to allow for clearance.
[0012] Furthermore, the multiple corner support plates are evenly spaced along the height direction of the external corner decorative plate.
[0013] Furthermore, a rubber strip is adhered to the edge of the external corner insulation board facing the adjacent straight composite board on the wall sidewall. The thickness of the rubber strip is the same as that of the external corner insulation board, and the width of the rubber strip protrudes from the edge of the external corner decorative board. The edge of the straight composite board decorative board can overlap the rubber strip.
[0014] Furthermore, the rubber strip is a hollow rectangular column shape, and the rubber strip is made of EPDM rubber material.
[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0016] This utility model discloses an integrated composite panel for exterior wall insulation and decoration. By designing both the corner decorative panel and the corner insulation panel as a single, integrally formed right-angle shape, it avoids the need for seams at the directly opposite corner, ensuring the integrity of the insulation and decorative layers at the building's corner. This results in a more aesthetically pleasing appearance and improved insulation performance. When applied to building corners, this integrated composite panel for exterior wall insulation and decoration employs a seamless design, guaranteeing the integrity of the insulation layer at the corners.
[0017] Furthermore, by creating a clearance groove at the inner corner apex of the external corner insulation board, it can prevent unevenness or burrs at the external corner of the building wall from hindering the smooth application of this utility model of integrated external wall insulation and decoration composite board; on the other hand, it can accommodate excess adhesive mortar, ensuring a uniform bonding effect. Adding corner support plates at the inner corner of the external corner decorative board supports the two side walls of the board, increasing the structural strength of the brittle ceramic or cement board and preventing breakage during transportation or on-site construction. The embedded installation of the corner support plates reduces the impact on the insulation layer. By setting rubber strips at the edge of the external corner insulation board facing the wall sidewall, the rubber strips, which are more compressible than the insulation board material, can withstand thermal stress deformation of the wall panel without causing the integrated external wall insulation and decoration composite board to be pushed off at the external corner; the hollow rectangular structure of the rubber strips further increases their compressive deformation capacity.

Detailed Implementation
[0025] The core of this utility model is to provide an integrated composite panel for exterior wall insulation and decoration, which is applied to the external corner of a building and is seamlessly treated to ensure the integrity of the insulation layer at the external corner of the building.
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In the following detailed description of the accompanying drawings, the descriptions of top, bottom, left, and right are all relative to the accompanying drawings and should not be construed as limiting the present utility model.
[0027] Refer to the attached diagram. Figure 1 This is a schematic diagram of the external corner structure of an exterior wall insulation and decoration composite panel in the prior art; Figure 2 This is a schematic diagram of another type of external wall insulation and decorative composite panel corner structure in the prior art; Figure 3 This is a three-dimensional structural diagram of the integrated composite panel for exterior wall insulation and decoration of this utility model; Figure 4 This is a schematic diagram of the main structure of the integrated composite panel for exterior wall insulation and decoration of this utility model; Figure 5 This is a schematic diagram of the main sectional view of the integrated composite panel for exterior wall insulation and decoration of this utility model.
[0028] In one specific implementation, such as Figures 3-5 As shown, an integrated composite panel for exterior wall insulation and decoration is used at the external corner of a building. It includes a corner decorative panel 1 and a corner insulation panel 3, both of which are integrally formed right-angled shapes, meaning there are no seams between the corner decorative panel 1 and the corner insulation panel 3 at the directly opposite positions of the external corner. The corner insulation panel 3 is bonded to the inner wall of the corner decorative panel 1 via an adhesive layer 2.
[0029] By designing both the external corner decorative panel 1 and the external corner insulation panel 3 as integrally formed right-angled shapes, seams can be avoided at the directly opposite positions of the external corners, ensuring the integrity of the insulation and decorative layers at the building's external corners. This results in a more aesthetically pleasing appearance and improved insulation performance. This utility model of an integrated composite panel for external wall insulation and decoration, applied to building external corners, employs a seamless design to guarantee the integrity of the insulation layer at the building's external corners.
[0030] Specifically, the exterior wall insulation and decoration integrated composite panel of this utility model, like existing technologies, is fixed using a combination of mortar bonding and anchoring. The anchors are fixed to the exterior wall of the building, and the upper and lower side walls of the corner decorative panel 1 have grooves that mate with the anchors. These grooves are not shown in the accompanying drawings and should not be considered a limitation of this utility model.
[0031] Specifically, such as Figures 3-5 As shown, the external corner decorative panel 1 is specifically made of ceramic, metal plate or fiber cement board.
[0032] Specifically, such as Figures 3-5 As shown, the external corner insulation board 3 is specifically made of polystyrene foam board, extruded polystyrene board, polyurethane foam board, or rock wool board. When rock wool board is used to make the external corner insulation board 3, cement fiber board needs to be laminated on the inner wall of the external corner insulation board 3 as a base material.
[0033] In one specific embodiment of this utility model, such as Figures 3-5 As shown, a relief groove 5 is provided at the inner corner vertex of the external corner insulation board 3. The relief groove 5 is an arc-shaped groove. The relief groove 5 is provided along the entire length of the external corner insulation board 3.
[0034] By opening a relief groove 5 at the inner corner vertex of the external corner insulation board 3, on the one hand, it can avoid the inability to smoothly adhere the integrated composite board of external wall insulation and decoration when the external corner of the building is uneven or has foreign objects or burrs; on the other hand, it can accommodate excess adhesive mortar and ensure uniform bonding effect.
[0035] In one specific embodiment of this utility model, such as Figures 3-5 As shown, the integrated composite panel for exterior wall insulation and decoration of this utility model also includes a corner support plate 6. The corner support plate 6 is made of the same material as the external corner decorative panel 1, and the corner support plate 6 is a right-angled triangle. The corner support plate 6 is bonded to the inner corner of the external corner decorative panel 1 by an adhesive layer 2. The corner support plate 6 is embedded in the external corner insulation board 3, and the external corner insulation board 3 has a recessed groove for clearance in the corner support plate 6.
[0036] Specifically, such as Figure 5 As shown, multiple corner support plates 6 are evenly spaced along the height direction of the external corner decorative plate 1.
[0037] By adding corner support plates 6 at the inner corners of the external corner decorative panel 1 to support the two side walls of the external corner decorative panel 1, the structural strength of the brittle ceramic or cement board is increased, preventing breakage during transportation or on-site construction. The recessed installation of the corner support plates 6 also reduces the impact on the insulation layer.
[0038] In one specific embodiment of this utility model, such as Figures 3-5 As shown, a rubber strip 4 is adhered to the edge of the adjacent straight composite panel facing the wall side of the external corner insulation board 3. The rubber strip 4 runs the length of the composite panel along its height, and its thickness is the same as that of the external corner insulation board 3. The rubber strip 4 partially protrudes from the edge of the external corner decorative panel 1 in the width direction. The edge of the decorative panel 1' of the straight composite panel can overlap the rubber strip 4. In other words, the joint between the external corner composite panel and the adjacent straight composite panel is on the rubber strip 4. After assembly, weather-resistant sealant is used to grout the joint.
[0039] Specifically, such as Figures 3-5As shown, rubber strip 4 is a hollow rectangular column shape and is made of EPDM rubber.
[0040] By setting a rubber strip 4 at the edge of the external corner insulation board 3 facing the side wall, the rubber strip 4 has stronger compressibility than the insulation board material, and can be squeezed and deformed under thermal stress deformation of the wall panel, so that the external wall insulation and decoration integrated composite board of this utility model will not be pushed off at the external corner; by setting the rubber strip 4 to a hollow rectangular structure, its pressure-bearing deformation capacity is increased.
[0041] The construction process of this embodiment of the integrated exterior wall insulation and decoration composite panel is as follows: During the construction of the exterior wall cladding and insulation, the corner composite panel and straight composite panel of this utility model are bonded and anchored layer by layer with mortar. First, the integrated exterior wall insulation and decoration composite panel of this utility model is installed at the external corner of the building. Anchors are set at the top and bottom ends, and adhesive mortar is used to bond the large surface for a firm connection. Then, the straight composite panel is bonded and anchored from the external corner to both sides. Note that for the straight composite panel spliced with the rubber strip 4, a tool is needed to remove one strip of the insulation board 3' on the side of the straight composite panel facing the joint, so that the remaining decorative board 1' overlaps the rubber strip 4, and is about 5 mm away from the edge of the external corner decorative board 1 of this utility model. All joints are then grouted with sealant.
[0042] In summary, by designing both the corner decorative panel 1 and the corner insulation panel 3 as integrally formed right-angled shapes, seams can be avoided at the directly opposite corners, ensuring the integrity of the insulation and decorative layers at the building's corners. This results in a more aesthetically pleasing appearance and improved insulation performance. This utility model of an integrated exterior wall insulation and decoration composite panel, applied to building corners, employs a seamless design to ensure the integrity of the insulation layer at the corners. Furthermore, by creating a clearance groove 5 at the inner corner apex of the corner insulation panel 3, it prevents unevenness or burrs at the exterior wall corners from hindering smooth adhesion of the integrated exterior wall insulation and decoration composite panel; it also accommodates excess adhesive mortar, ensuring a uniform bonding effect. Adding a corner support plate 6 at the inner corner of the corner decorative panel 1 supports the two side walls of the corner decorative panel 1, increasing the structural strength of the brittle ceramic or cement board and preventing breakage during transportation or on-site construction. The embedded installation of the corner support plate 6 reduces the impact on the insulation layer. By setting a rubber strip 4 at the edge of the external corner insulation board 3 facing the side wall, the rubber strip 4 has stronger compressibility than the insulation board material, and can be squeezed and deformed under thermal stress deformation of the wall panel, so that the external wall insulation and decoration integrated composite board of this utility model will not be pushed off at the external corner; by setting the rubber strip 4 to a hollow rectangular structure, its pressure-bearing deformation capacity is increased.
[0043] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
