Technical Field

[0001] The invention belongs to the technical field of building wall decoration installation, and particularly relates to an installation structure of a heat-insulating, moisture-proof and sound-absorbing decorative panel for a building wall and a construction method thereof. Background Art

[0002] In the field of building wall decoration and functional improvement, as people's requirements for the quality of living environment continue to increase, traditional wall decoration materials can no longer meet the comprehensive needs of modern buildings for integrated insulation, moisture-proofing, sound absorption and decoration. In recent years, with the rapid development of materials science and construction technology, a variety of new wall decoration materials have emerged on the market. These materials use advanced composite technology to organically combine material layers with different functions, in order to achieve multiple performance improvements in a single product.

[0003] Specifically, in terms of thermal insulation performance, high-efficiency thermal insulation materials such as extruded boards and polyurethane foam are widely used in wall insulation systems, effectively reducing the energy consumption of buildings; in terms of moisture-proof performance, the development and application of waterproof fiber tile adhesive layers and waterproof coatings have significantly improved the wall's ability to resist moisture erosion; and in terms of sound absorption performance, the introduction of porous materials such as mineral wool boards and sound-absorbing cotton has effectively improved the indoor acoustic environment. However, although these single-function materials have achieved remarkable results in their respective fields, in actual engineering applications, how to effectively integrate these functional materials into the same wall decoration system and ensure their installation accuracy and structural stability is still a problem that needs to be solved, so staff need to improve it. Summary of the Invention

[0004] The object of the present invention is to provide an installation structure and a construction method of a thermal insulation, moisture-proof and sound-absorbing decorative panel for a building wall, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The installation structure of the building wall thermal insulation, moisture-proof and sound-absorbing decorative panels includes:

[0007] Decorative panel assembly;

The first waterproof fiber tile adhesive layer is bonded to the metal decorative panel and the first alkali-resistant high-strength fiber layer. The first alkali-resistant high-strength fiber layer is fixed to the outer surface of the aluminum honeycomb core and the extruded board composite layer by a hot-pressing composite method. The second alkali-resistant high-strength fiber layer is bonded to the inner surface of the aluminum honeycomb core and the extruded board composite layer by a hot-pressing composite method. The second waterproof fiber tile adhesive layer is bonded to the outer surface of the second alkali-resistant high-strength fiber layer.

[0009] The back of the decorative component is overlapped with an adjustable metal keel, and an adjustable fixing code is installed on the back of the adjustable metal keel. The inner wall of the adjustable metal keel is threaded with a fixing screw, and the surface of the decorative component is threaded with a self-drilling screw. A filling hole is opened on the surface of the decorative component, and the inner wall of the filling hole is sleeved on the surface of the self-drilling screw.

[0010] Preferably, the back side of the adjustable metal keel is threadedly connected with an expansion screw, and the surface of the expansion screw is provided with a wall.

Keel installation and positioning: Mark the installation position of the adjustable metal keel on the wall surface, drill holes and install expansion screws, fix the adjustable fixing brackets to the wall with the expansion screws, adjust the level of the adjustable metal keel, and lock it with the fixing screws;

[0013] S2. Pre-assembly of decorative panel components: Hot-press the aluminum honeycomb core and the extruded board composite layer to form a first alkali-resistant high-strength fiber layer and a second alkali-resistant high-strength fiber layer, apply a first waterproof fiber tile adhesive layer to the outer surface of the first alkali-resistant high-strength fiber layer and adhere the metal decorative panel to the layer, and apply a second waterproof fiber tile adhesive layer to the outer surface of the second alkali-resistant high-strength fiber layer;

[0014] S3. Fix the decorative panel assembly: Overlap the back of the decorative panel assembly on the adjustable metal keel. Use self-drilling screws to penetrate the decorative panel assembly from the outer surface of the metal decorative panel. Ensure that the heads of the self-drilling screws are embedded in the filling holes and flush with the surface of the metal decorative panel.

[0015] S4. Sealing treatment of joints: Fill the joints of adjacent decorative panel components with weather-resistant glue.

[0018] Preferably, in step S4, the filling depth of the front-fed glue is ≥5 mm, and forms an angled seam of 45° to 60° with the edge of the metal decorative panel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The precise positioning and stable installation of the decorative panel components are achieved through the coordinated arrangement of the adjustable metal keel, the adjustable fixing code and the self-drilling screws. The adjustable metal keel can flexibly adjust the horizontal position according to the flatness of the wall. The self-drilling screws penetrate the decorative panel and overlap with the fixing screws to form a double fixation, thereby achieving the effect of improving the installation accuracy and enhancing the structural stability, while avoiding the deformation or loosening of the panel commonly encountered in traditional installation methods.

[0021] (2) Through the setting of multi-layer composite materials, including metal decorative panels, waterproof fiber tile adhesive layers, alkali-resistant high-strength fiber layers, and aluminum honeycomb core and extruded board composite layers, the decorative panel components have the functions of heat preservation, moisture resistance, sound absorption and decoration. The various layers of materials are tightly combined through hot pressing and gluing processes, thereby achieving the effect of improving the overall performance of the wall, which not only meets the energy-saving requirements of the building, but also enhances the durability and environmental adaptability of the structure.

[0042] Example 2:

[0046] Structure Description:

[0047] Compared with the first embodiment, the present embodiment omits the adjustable metal keel system and adopts a simplified structure in which the decorative panel assembly is directly fixed to the wall.

[0048] The functional layers are tightly combined by hot pressing and gluing to form an integral composite panel structure.

[0049] The matching design of the self-drilling screw 11 and the filling hole 12 ensures the surface flatness after installation.

[0050] The expansion screws 13 pass directly through the decorative panel assembly 1 and are fixed to the wall 14, simplifying the installation process.

[0051] Application examples:

[0052] A high-rise commercial office building is located in a coastal area with a humid and rainy climate and high surrounding traffic noise. To meet the insulation, moisture-proofing, sound absorption and aesthetic requirements of the building's exterior walls, the owner decided to adopt the installation structure of the building wall insulation, moisture-proofing and sound-absorbing decorative panels described in the present invention. This decorative panel system must not only have excellent thermal insulation performance to reduce energy consumption, but also effectively prevent moisture to cope with high humidity environments. At the same time, it must have a sound-absorbing function to reduce the impact of traffic noise on the indoor environment. In addition, the exterior finish must meet the aesthetic requirements of modern commercial buildings to ensure an overall high-end appearance.

[0053] Carry out a comprehensive inspection of the building's exterior walls to ensure that the base wall (concrete structure) is flat and free of cracks, and complete waterproofing treatment.

[0054] According to the design drawings, mark the installation position of the adjustable metal keel on the wall surface with a spacing of 600mm to ensure that the horizontality and verticality meet the requirements.

[0055] Use an electric drill to drill holes at the marked locations to a depth of 50 mm and a diameter that matches the expansion screw.

[0056] Insert the expansion screws into the holes and fix the adjustable metal keel to the wall through the adjustable fixing code.

[0057] Use a spirit level to adjust the level of the keel and tighten it with the fixing screws to ensure that the keel system is stable and flat.

[0058] The first alkali-resistant high-strength fiber layer and the second alkali-resistant high-strength fiber layer are hot-pressed on both sides of the aluminum honeycomb core and the extruded board composite layer to form a core functional layer.

[0059] A 2mm thick first waterproof fiber tile adhesive layer is coated on the outer surface of the first alkali-resistant high-strength fiber layer, and a metal decorative panel (a fluorocarbon-coated aluminum plate with a silver-gray color) is bonded thereto.

[0060] A 2mm thick second waterproof fiber tile adhesive layer is coated on the outer surface of the second alkali-resistant high-strength fiber layer for bonding with the wall.

[0061] After prefabrication is completed, it is transported to the construction site to avoid bumps and humid environments.

[0062] Overlap the back of the prefabricated decorative panel assembly on the adjustable metal keel and install it piece by piece from bottom to top.

[0063] Use self-drilling screws to penetrate the decorative panel assembly from the outer surface of the metal decorative panel. The screw spacing is 400mm and the tightening torque is 2N·m. Make sure that the screw head is embedded in the filling hole and flush with the surface of the decorative panel.

[0064] During the installation process, check the flatness of the board surface and the uniformity of the joints at any time, and adjust the tightness of the screws to fine-tune the position.

[0065] Fill the joints of adjacent decorative panel components with weather-resistant glue (silicone weather-resistant glue is selected) with a filling depth of 5mm, and form a 50° bevel joint with the edge of the metal decorative panel to ensure waterproofness and aesthetics.

[0066] Use a scraper to trim the glue seam to make it smooth and even.

[0067] After the installation is completed, the entire exterior wall is inspected to check the thermal insulation performance (detected by a thermal imager), moisture-proof effect (observe whether there are signs of water seepage) and sound absorption performance (through decibel testing).

[0068] During regular maintenance, focus on checking the aging of the weather-resistant glue and perform glue repair if necessary.

[0069] Working Principle: From the outside in, the decorative panel assembly consists of a metal veneer, a first waterproof fiber tile adhesive layer, a first alkali-resistant high-strength fiber layer, an aluminum honeycomb core and extruded board composite layer, a second alkali-resistant high-strength fiber layer, and a second waterproof fiber tile adhesive layer. Each layer is tightly bonded together through a hot-pressing and gluing process: the metal veneer provides aesthetics and protection, the waterproof fiber tile adhesive layer ensures moisture resistance and bond strength, the alkali-resistant high-strength fiber layer enhances overall tensile strength, and the aluminum honeycomb core and extruded board composite layer serves as the core functional layer. The aluminum honeycomb core imparts lightweight, high strength, and sound absorption properties to the structure, while the extruded board provides efficient thermal insulation. The decorative panel assembly is secured to the wall via an adjustable metal keel system on the back (or directly via expansion screws). The adjustable metal keel and adjustable fixing brackets allow for precise leveling. Self-drilling screws penetrate the decorative panel and overlap with the fixing screws, creating a mechanical lock that ensures a secure installation and a smooth surface. The filler holes ensure that the screw heads are flush with the decorative panel to maintain aesthetics. The joints are filled with weather-resistant adhesive for a waterproof seal. During construction, through layered assembly, precise fixing and sealing, a wall system that is both functional, durable and decorative is finally formed.
