Description

Technical Field

[0001] The present application relates to the technical field of building construction, and more specifically, to a thermal insulation decorative board assembly. Background Art

[0002] In recent years, large-area cracks, peeling, etc. often occur on the exterior wall surface of buildings, posing potential safety hazards and causing property losses.

[0003] Existing renovation methods require removing the exterior thermal insulation decorative layer and then installing a new thermal insulation decorative board, resulting in low renovation construction efficiency; during the process of removing the exterior thermal insulation decorative layer, a large amount of construction waste is generated, and potential safety hazards are easily caused during the construction process.

[0004] During the installation of the new thermal insulation decorative board, it needs to be fixed by ordinary plastic expansion bolts (which can also be called thermal insulation nails). To ensure the reinforcement effect, the number of thermal insulation nails is greater than 20 per square meter 2 , resulting in low construction efficiency and an increase in the number of thermal bridges; since holes need to be drilled for installing the thermal insulation nails, the construction process is noisy and continuous.

[0005] To meet the existing building energy-saving standards, the thickness of the thermal insulation layer is at least 150 mm, resulting in a relatively long length of the above-mentioned plastic expansion bolts and a relatively long overhanging distance. Due to the low stiffness of the plastic expansion bolts, the plastic expansion bolts are relatively easy to deform, resulting in a relatively easy occurrence of sliding of the overall thermal insulation layer, posing a great potential safety hazard to the exterior wall.

[0006] In summary, how to renovate the exterior wall surface to improve construction efficiency, reduce construction waste, and reduce potential safety hazards during the construction process is an urgent problem to be solved by those skilled in the art at present. Utility Model Content

[0049] Currently, in the face of problems such as cracks and peeling of building exterior walls, it is usually solved by removing the original external thermal insulation decorative layer and then installing a new thermal insulation decorative board. However, the existing renovation methods will generate a large amount of construction waste and also pose safety hazards during the construction process; when installing the new thermal insulation decorative board, it is usually fixed by ordinary plastic expansion bolts (also known as thermal insulation nails). To ensure the reinforcement effect, the number of thermal insulation nails needs to be greater than 20 per square meter. 2 This results in low construction efficiency and an increase in the number of thermal bridges. Since holes need to be drilled to install the thermal insulation nails, the installation process of a relatively large number of thermal insulation nails will continuously generate construction noise, affecting the living environment of residents; moreover, to meet the existing building energy efficiency standards, the thickness of the thermal insulation layer is at least 150 mm, resulting in a relatively long length of the above-mentioned plastic expansion bolts and a relatively far overhanging distance. Due to the low stiffness of the plastic expansion bolts, the plastic expansion bolts are relatively easy to deform, resulting in a relatively easy occurrence of a sliding phenomenon in the overall thermal insulation layer, posing a great safety hazard to the exterior wall.

[0050] To solve the above technical problems, the embodiments of the present application provide a thermal insulation decorative board assembly to renovate the exterior wall surface, so as to improve construction efficiency, reduce construction waste, and reduce safety hazards during the construction process.

[0051] Such as Figures 1 - 13As shown in the figure, the thermal insulation and decoration board assembly provided in this embodiment is fixed on the outer side of the base layer 300. The base layer 300 includes a wall body 302 and a thermal insulation and decoration layer 301 provided on the outer side of the wall body 302. Among them, the thermal insulation and decoration layer 301 is the original thermal insulation and decoration layer 301 that needs to be renovated. The thermal insulation and decoration board assembly covers the outer side of the original thermal insulation and decoration layer 301. On the basis of retaining the thermal insulation and decoration layer 301 that needs to be renovated, the exterior wall surface is renovated, that is, the exterior wall surface can be renovated without demolishing the thermal insulation and decoration layer 301 that needs to be renovated. In this way, the construction steps are reduced, the work efficiency is improved, the generation of construction waste is also reduced, and the potential safety hazards during the construction process are reduced.

[0052] As Figure 1 , Figure 7 and Figure 11 As shown in the figure, the thermal insulation and decoration board assembly provided in this embodiment includes a thermal insulation and decoration board 10 and a connection assembly 200. Among them, the thermal insulation and decoration board 10 includes a thermal insulation and decoration board main body 100 and a first connecting member 110 that are fixedly connected. The first connecting member 110 is fixed to the thermal insulation and decoration layer 301 and the wall body 302 through the connection assembly 200, so that the wall body 302, the thermal insulation and decoration layer 301, and the thermal insulation and decoration board 10 are distributed in sequence from the inside to the outside. In this way, through the connection of the first connecting member 110 and the connection assembly 200, the thermal insulation and decoration board 10 can be fixed on the outer side of the original thermal insulation and decoration layer 301, reducing the installation steps of the thermal insulation and decoration board 10 and improving the construction efficiency.

[0053] It should be noted that the thermal insulation and decoration board 10 further includes a second connecting member 120 fixedly connected to the thermal insulation and decoration board main body 100. The thermal insulation and decoration board main body 100, the first connecting member 110, and the second connecting member 120 constitute a thermal insulation and decoration board 10. In the vertical direction as shown in Figure 1 the figure, the first connecting member 110 is located above the thermal insulation and decoration board main body 100, and the second connecting member 120 is located below the thermal insulation and decoration board main body 100.

[0054] The thermal insulation and decoration board main body 100 includes a decoration layer 102 and a thermal insulation layer 101. The decoration layer 102 is provided with an embedded back groove type fixing connecting member. Both the first connecting member 110 and the second connecting member 120 are fixedly connected to the thermal insulation layer 101 and the decoration layer 102 through the embedded back groove type fixing connecting member, constituting a thermal insulation and decoration board 10. In this way, the thermal insulation and decoration board 10 can be connected to the original thermal insulation and decoration layer 301 through the first connecting member 110 and the connection assembly 200, improving the construction efficiency.

[0055] As Figure 1 , Figure 4 , Figure 7 and Figure 11As shown, the first connecting member 110 has a first outer connecting portion 1101 and a first inner connecting portion 1102, and the first outer connecting portion 1101 is perpendicular to the first inner connecting portion 1102, or the included angle between the first outer connecting portion 1101 and the first inner connecting portion 1102 is an acute angle or an obtuse angle. To improve the connection stability, the first outer connecting portion 1101 and the first inner connecting portion 1102 can be selected to be perpendicular to each other. A first connecting plate hole 11011 is formed in the first outer connecting portion 1101, and the built-in back groove type fixing connecting member on the decorative layer 102 is fixedly connected to the first connecting member 110 through the first connecting plate hole 11011, and there is an insertion gap between the first connecting plate 110 and the decorative layer 102.

[0056] As Figure 5 shown, a second connecting plate hole 1201 is formed at one end of the second connecting member 120, and the built-in back groove type fixing connecting member on the decorative layer 102 is fixedly connected to the second connecting member 120 through the second connecting plate hole 1201, and the other end of the second connecting member 120 away from the second connecting plate hole 1201 extends out of the thermal insulation decorative board main body 100 to form an extension portion. As Figure 1 、 Figure 7 and Figure 11 shown, during the installation process of two adjacent thermal insulation decorative boards 10, in the vertical direction, the extension portion of the second connecting member 120 in the upper thermal insulation decorative board 10 is fitted with the insertion gap between the first connecting member 110 and the decorative layer 102 in the lower thermal insulation decorative board 10, so that the adjacent thermal insulation decorative boards 10 are positioned relative to each other during the installation process, further improving the construction efficiency.

[0057] In actual situations, to ensure the sealing of the overall installation, two adjacent thermal insulation decorative boards 10 are hermetically connected through a sealing member 103. Specifically, the sealing member 103 includes a polyethylene foam strip 1031 filled in the splicing gap between the two thermal insulation decorative boards 10 and a silicone sealant 1032 for sealing the gap, which can form a good sealing and waterproof effect, and at the same time can reduce the edge chipping and damage at the connection position between adjacent thermal insulation decorative boards 10 after freeze-thaw cycles.

[0058] As Figure 4 shown, a connecting member hole 11021 is formed in the first inner connecting portion 1102, and the first connecting member 110 is fixedly connected to the connecting component 200 through the connecting member hole 11021. In this way, the connection between the first connecting member 110 and the connecting component 200, through the extension and fixation of each connecting member in the vertical and horizontal directions, reduces the number of bolts that need to be drilled and fixed, reduces the number of holes drilled in the thermal insulation decorative board 10, and thus reduces the noise during the construction process.

[0059] To ensure a fixed connection with the base layer 300, the connection assembly 200 includes a wall-embedded member 204, and the wall-embedded member 204 is fixedly connected to the thermal insulation decorative layer 301 and the wall 302 through expansion bolts 207. As Figure 1 shown, the expansion bolts 207 pass through the wall-embedded member 204, the thermal insulation decorative layer 301, and the wall 302, which can increase the connection strength between the wall-embedded member 204 and the base layer 300.

[0060] Exemplarily, as Figure 1 、 Figure 7 、 Figure 11 shown, the wall-embedded member 204 is located inside the thermal insulation decorative layer 301. A groove for placing the wall-embedded member 204 can be opened on the thermal insulation decorative layer 301, so that the wall-embedded member 204 can be embedded in the thermal insulation decorative layer 301, further strengthening the connection strength of the wall-embedded member 204. Or, the wall-embedded member 204 can be directly fixedly connected to the outer surface of the thermal insulation decorative layer 301, reducing the construction steps and improving the construction efficiency.

[0061] As Figure 1 、 Figure 6 、 Figure 7 and Figure 11 shown, the connection assembly 200 further includes a wall connection member 203 connecting the first connection member 110 and the wall-embedded member 204. The wall connection member 203 has an inner wall connection portion 2032 and an outer wall connection portion 2031. The inner wall connection portion 2032 and the outer wall connection portion 2031 are perpendicular to each other, or the included angle between the inner wall connection portion 2032 and the outer wall connection portion 2031 is an acute angle or an obtuse angle. To improve the connection stability, the inner wall connection portion 2032 and the outer wall connection portion 2031 can be selected to be perpendicular to each other. A second wall connection hole 20321 is opened on the inner wall connection portion 2032, and the first threaded fastener 205 can fixedly connect the wall connection member 203 and the wall-embedded member 204 through the second wall connection hole 20321; a first wall connection hole 20311 is opened on the outer wall connection portion 2031, and the second threaded fastener 206 can fixedly connect the wall connection member 203 and the first connection member 110 through the first wall connection hole 20311 and the connection hole 11021. In this way, the wall-embedded member 204 and the first connection member 110 are fixedly connected through the wall connection member 203, realizing the fixed connection between the thermal insulation decorative panel 10 and the original thermal insulation decorative layer 301.

[0062] Due to installation errors in the actual installation process, for the convenience of installation, as Figure 6As shown, the first wall connection hole 20311 and the second wall connection hole 20321 are both strip-shaped holes, specifically, they can be waist-shaped holes or rectangular holes, etc. In this way, it is convenient for the first connector 110, the wall connector 203 and the wall-embedded part 204 to be connected, and reduces the probability that the first connector 110, the wall connector 203 and the wall-embedded part 204 cannot be assembled due to processing errors, installation errors, etc.

[0063] In some embodiments, such as Figure 6 As shown, the length directions of the first wall connection hole 20311 and the second wall connection hole 20321 are perpendicular to each other. In this way, during the connection process of the wall connector 203 with the first connector 110 and the wall-embedded part 204, adjustment can be carried out in both the horizontal and vertical directions, further reducing the probability that the first connector 110, the wall connector 203 and the wall-embedded part 204 cannot be assembled.

[0064] In other embodiments, the length directions of the first wall connection hole 20311 and the second wall connection hole 20321 are the same. In this way, during the connection process of the wall connector 203 with the first connector 110 and the wall-embedded part 204, the adjustment distance is further increased in the horizontal or vertical direction, further reducing the probability that the first connector 110, the wall connector 203 and the wall-embedded part 204 cannot be assembled.

[0065] During the actual installation process, the insulation decorative board 10 and the insulation decorative layer 301 are first bonded by polyurethane foam adhesive 104 or other adhesives, and then fixedly connected to the first connector 110 through the connection assembly 200, ensuring the installation stability of the insulation decorative board 10 and reducing the sliding phenomenon of the insulation decorative board 10 after installation.

[0066] Due to the reduced stiffness of the ordinary plastic expansion bolts in the traditional installation method, in order to increase the connection strength, the wall-embedded part 204, the wall connector 203, the expansion bolt 207, the first threaded fastener 205, and the second threaded fastener 206 in the embodiments of the present application are all metal parts, which can increase the connection stiffness of the connection assembly 200, reduce the probability of the insulation decorative board 10 sliding down, reduce the potential safety hazards of the exterior wall, and improve the safety of the insulation decorative board 10 after installation; the number of expansion bolts 207 can be reduced, the construction efficiency can be improved, and the number of drilled holes can also be reduced, reducing the duration of construction noise.

[0067] Since metal parts are more prone to heat conduction, in order to reduce the heat bridge effect, an adiabatic gasket is provided at the connection part to isolate heat conduction. Specifically, such as Figures 1 - 13As shown in the figure, first heat insulation gaskets 208 are arranged on both sides of the wall embedding member 204, and the expansion bolt 207 passes through the first heat insulation gaskets 208, which can isolate the heat conduction at the connection part between the expansion bolt 207 and the wall embedding member 204; in the wall connecting member 203, second heat insulation gaskets 209 are arranged on both sides of the inner wall connecting part 2032, and the first threaded fastener 205 passes through the second heat insulation gaskets 209, which can isolate the heat conduction at the connection part between the first threaded fastener 205 and the wall connecting member 203. Third heat insulation gaskets 210 are arranged on both sides of the outer wall connecting member 2031, and the second threaded fastener 206 passes through the third heat insulation gaskets 210, which can isolate the heat conduction at the connection part between the second threaded fastener 206 and the wall connecting member 203. By arranging the first heat insulation gaskets 208, the second heat insulation gaskets 209, and the third heat insulation gaskets 210, the number of heat bridges is reduced, thereby reducing the heat bridge effect of the thermal insulation decorative board 10 when the indoor temperature difference is large and prolonging the service life of the thermal insulation decorative board 10.

[0068] In the wall embedding member 204 provided in the embodiment of the present application, a first connection hole 2041 through which the expansion bolt 207 can pass is provided, and a second connection hole 2042 corresponding to the second wall connection hole 20321 in the wall connecting member 203, so that the first threaded fastener 205 can be fixedly connected to the second wall connection hole 20321 through the second connection hole 2042 to fix the wall embedding member 204 and the wall connecting member 203.

[0069] During the installation process of the thermal insulation decorative board assembly provided in the embodiment of the present application, first, the wall embedding member 204 is fixedly connected to the thermal insulation decorative layer 301 and the wall 302 through the expansion bolt 207. Then, the thermal insulation decorative board main body 10 is bonded to the thermal insulation decorative layer 301 through the polyurethane foam adhesive 104. Then, the wall connecting member 203 is fixedly connected to the wall embedding member 204 and the first connecting member 110 through the first threaded fastener 205 and the second threaded fastener 206 respectively to complete the installation and fixation of one thermal insulation decorative board 10. Then, the second connecting member 120 in the vertically adjacent thermal insulation decorative boards 10 is fitted and positioned with the insertion gap between the first connecting member 110 and the thermal insulation decorative board main body 100 in the already installed and fixed thermal insulation decorative board 10. Then, continue the above installation steps to complete the installation of all the thermal insulation decorative boards 10. In this way, on the basis of retaining the original thermal insulation decorative layer 301, new thermal insulation decorative boards 10 are installed, reducing the generation of construction waste, improving the construction efficiency, and also reducing the potential safety hazards during the construction process.

[0070] To adapt to different installation situations, the wall embedding member 204 has different structures, which will be specifically described through three embodiments.

[0071] Embodiment 1

[0072] As Figures 1 - 3As shown, in a connection component 200, an expansion bolt 207 is connected to the base layer 300. In order for the expansion bolt 207 to pass through, the number of first connection holes 2041 opened in the wall embedded part 204 is one.

[0073] As Figure 3 shown, the first connection hole 2041 and the second connection hole 2042 are arranged in sequence along the vertical direction as Figure 1 shown, ensuring the force balance of the expansion bolt 207. Due to installation errors during the actual installation process, both the first connection hole 2041 and the second connection hole 2042 are elongated holes. Exemplarily, as Figure 3 shown, the elongated hole can be an oval hole; or the elongated hole is a rectangular hole. In this way, it is convenient for the expansion bolt 207 and the first fastener 205 to be connected to the wall embedded part 204, reducing the probability that the expansion bolt 207 and the first fastener 205 cannot be assembled due to processing errors, installation errors, etc.

[0074] As Figure 3 shown, the length directions of the first connection hole 2041 and the second connection hole 2042 are perpendicular to each other, capable of accommodating installation errors in two directions (the length direction of the first connection hole 2041 and the length direction of the second connection hole 2042).

[0075] During the actual installation process, to ensure the stability of the installation, in a thermal insulation decorative board component, there can be multiple connection components 200. As Figure 2 shown, in a thermal insulation decorative board component, there are two connection components 200. There is a certain installation distance between the two connection components 200. Each connection component 200 has an expansion bolt 207, further improving the connection strength and the installation stability of the thermal insulation decorative board 10.

[0076] Embodiment 2

[0077] As Figures 7 - 10 shown, in a connection component 200, two expansion bolts 207 are connected to the base layer 300. In order for the expansion bolts 207 to pass through, the number of first connection holes 2041 opened in the wall embedded part 204 is two.

[0078] As Figure 9 and Figure 10As shown, to ensure the force balance of the expansion bolt 207, the first connection hole 2041 and the second connection hole 2042 are distributed horizontally, and the second connection hole 2042 is located between the two first connection holes 2041. Due to installation errors in the actual installation process, both the first connection hole 2041 and the second connection hole 2042 are strip-shaped holes, specifically, they can be waist-shaped holes or rectangular holes, etc. In this way, it is convenient to connect the expansion bolt 207, the first fastener 205 and the wall-embedded member 204, and reduces the probability that the expansion bolt 207, the first fastener 205 and the wall-embedded member 204 cannot be assembled due to processing errors, installation errors, etc.

[0079] In some embodiments, as Figure 9 shown, the length directions of the two first connection holes 2041 and the second connection hole 2042 are the same, so that during the installation process, the distance between the two expansion bolts 207 can be finely adjusted to provide installation space.

[0080] In some other embodiments, as Figure 10 shown, the length directions of the two first connection holes 2041 are perpendicular to each other, so that one of the expansion bolts 207 can be positioned, ensuring the installation distance between the two expansion bolts 207 and further ensuring the force balance of the two expansion bolts 207.

[0081] In some other embodiments, the length directions of the two first connection holes 2041 are the same, and the length direction of the second connection hole 2042 is perpendicular to the length directions of the two first connection holes 2041, which can be adjusted in two directions (the length direction of the first connection hole 2041 and the length direction of the second connection hole 2042), further reducing the probability that the expansion bolt 207, the first fastener 205 and the wall-embedded member 204 cannot be assembled due to processing errors, installation errors, etc.

[0082] During the actual installation process, to ensure the stability of the installation, in a thermal insulation decorative board assembly, there can be multiple connection assemblies 200, as Figure 8 shown, there are two connection assemblies 200 in a thermal insulation decorative board assembly, and there is a certain installation distance between the two connection assemblies 200. Each connection assembly 200 has two expansion bolts 207, which further improves the connection strength and the installation stability of the thermal insulation decorative board 10.

[0083] Embodiment III

[0084] As Figures 11 - 13As shown, in a connection component 200, a plurality of expansion bolts 207 are connected to the base layer 300. In order to allow the expansion bolts 207 to pass through, the number of first connection holes 2041 opened in the wall embedded member 204 corresponds to the number of expansion bolts 207. Since the plurality of first connection holes 2041 will make the wall embedded member 204 longer, in order to ensure the force balance of the plurality of expansion bolts 207, in a connection component 200, there are two wall connection members 203. Two second connection holes 2042 are opened in the wall embedded member 204 for connecting with the two wall connection members 203, and the first connection holes 2041 corresponding to the number of expansion bolts 207 are located between the two second connection holes 2042. The first connection holes 2041 and the two second connection holes 2042 are arranged in sequence along the Figure 12 horizontal direction as shown.

[0085] For example, the number of expansion bolts 207 can be one, two or more than three, and the corresponding number of first connection holes 2041 can be one, two or more than three. The embodiments of the present application do not limit this.

[0086] Exemplarily, as Figures 12 - 13 shown, the wall embedded member 204 is provided with three first connection holes 2041 and two second connection holes 2042. All three first connection holes 2041 are located between the two second connection holes 2042, so that the three expansion bolts 207 can be balanced in force, and both sides of the wall embedded member 204 are connected to the wall connection member 203, further improving the connection strength and stability.

[0087] When the number of first connection holes 2041 is more than three, in order to ensure the plate strength of the wall embedded member 204 itself, as Figure 13 shown, the first connection holes 2041 are circular holes, and the second connection holes 2042 are long strip-shaped and form open holes. The length direction of the second connection holes 2042 is the same as the length direction of the wall embedded member 204, so that an installation error space can be provided while ensuring the plate strength of the wall embedded member 204 itself, which is convenient for installation with the wall connection member 203.

[0088] As Figure 12 shown, since the three expansion bolts 207 can provide good connection strength and the wall embedded member 204 is longer when three first connection holes 2041 are opened, in a thermal insulation decorative board assembly, only one connection component 200 can be provided. One connection component 200 has two wall connection members 203 connected to the wall embedded member 204, ensuring the connection strength and the installation stability of the thermal insulation decorative board 10.

[0089] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
