Description

Technical Field

[0001] This utility model relates to the field of decorative panel structure technology, and in particular to a fireproof decorative panel structure and installation structure for building. Background Technology

[0002] In the current field of interior and exterior wall decoration, integrated aluminum insulation and decoration panels and aluminum single panels have become the mainstream choices due to their strong decorative properties and convenient construction. The former often adopts a composite structure of "surface aluminum panel + middle insulation layer + back panel", while the latter is often a single-layer or simple composite aluminum structure. Both need to be fixed to the wall by keel, brackets, etc., and are suitable for various building scenarios.

[0003] However, existing products have obvious technical defects: First, the coefficients of thermal expansion and contraction of aluminum plates and core layers or insulation layers differ greatly, and the core layers are mostly flat or unidirectional support structures. The interlayer bonding relies mainly on ordinary adhesives, which cannot effectively buffer the interlayer stress caused by temperature changes. Long-term use can easily lead to warping, cracking, and coating peeling of the plates, damaging the flatness of the decorative surface and affecting the aesthetics of the building. Second, during installation, direct screw fixing or simple bracket connection is mostly used, lacking targeted reinforcement and stress dispersion structures. As the adhesive layer ages and the brackets loosen, especially in high-rise buildings, high wind pressure, or environments with drastic temperature differences, the plates are prone to loosening or even falling off, posing safety hazards.

[0004] Therefore, in response to the above phenomenon, a fireproof decorative panel structure and installation structure for buildings are proposed to meet the needs of practical use. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0026] I. Structure of Fire-Resistant Decorative Building Panels

[0027] This embodiment discloses a fireproof decorative panel structure for building applications, such as... Figure 1 As shown, the decorative panel body 100 includes an aluminum plate 102, a three-dimensional aluminum core 104, and an aluminum back plate 106:

[0028] Aluminum Plate 102 is made of aluminum alloy, which has good ductility and strength. As a decorative surface, it can be adapted to complex shapes through stamping, bending and other processes. At the same time, aluminum alloy is a non-combustible material (complies with GB8624-2012 "Classification of Combustion Performance of Building Materials and Products" A2 level), which improves the overall fire resistance.

[0029] The 104 three-dimensional aluminum core is made of rolled aluminum alloy, and its horizontal cross-section (along the width of the plate) and horizontal longitudinal cross-section (along the length of the plate) both have a wavy structure (e.g., Figure 1-2 As shown in the figure, the specific waveform is sinusoidal. This structure forms a honeycomb support skeleton through a "bidirectional wave" design, which increases the bending strength by more than 40% compared to the traditional flat core layer under the same weight. At the same time, the gaps between the waves form an air isolation layer, which slows down heat transfer and enhances the fireproof and heat insulation effect.

[0030] The aluminum back panel 106 is made of pure aluminum, which has excellent corrosion resistance. As a back panel, it can isolate the wall moisture from penetrating the core layer, prevent the three-dimensional aluminum core 104 from oxidizing and rusting, and further enhance the non-combustibility of the overall structure.

[0031] The upper and lower surfaces of the three-dimensional aluminum core 104 are connected to the aluminum plate 102 and the aluminum back plate 106 respectively through a first polymer film 103 and a second polymer film 105. The polymer films are modified EVA films, and their functions include:

[0032] 1. Bonding and fixing: The EVA film is melted through a hot pressing process, which firmly bonds the three-layer aluminum structure into a whole;

[0033] 2. Stress buffering: The flexibility of EVA is used to offset the interlayer stress caused by the difference in the coefficients of thermal expansion and contraction between aluminum plate 102, aluminum back plate 106 and three-dimensional aluminum core 104, so as to avoid delamination and blistering after long-term use.

[0034] The first coating layer is either a polyester coating or a fluorocarbon coating. Polyester coatings are preferred for indoor use due to their excellent weather resistance and decorative properties; they can be applied using a roller coating process to create textures such as wood grain and stone grain. Fluorocarbon coatings offer even better weather resistance and are also preferred for indoor use, exhibiting outstanding resistance to acid rain and salt spray, making them suitable for extreme environments such as coastal areas and highly polluted areas. Both are non-combustible coatings with a surface hardness ≥2H, meeting the wear resistance requirements for architectural decoration.

[0035] The second coating layer is a polyethylene (PE) coating. The PE coating has low surface energy and water resistance, which can prevent moisture from the wall 5 from penetrating into the aluminum back panel 106, while reducing frictional damage between the back panel and the wall 5 during installation and improving the moisture-proof life of the panel.

[0036] The first coating layer of the aluminum plate 102 is provided with a protective film 101, which is made of PET release film. It is applied to the coating surface before leaving the factory to prevent the coating from being scratched or contaminated during transportation and installation. It can be removed before project acceptance.

[0037] II. Installation Structure of Fireproof Decorative Panels for Buildings

[0038] Based on the above-mentioned panel structure, this section provides two different installation embodiments, both of which are suitable for interior and exterior wall decoration, as follows:

[0039] Example 1

[0040] The installation structure in this embodiment is as follows: Figure 3-6 As shown, it includes a first connecting bracket 1, four Z-shaped brackets 2, a U-shaped reinforcing rod 3, and a connecting block 4. The specific installation steps and structural features are as follows:

[0041] Edge processing is performed on the decorative panel body 100: V-shaped grooves are made along the four edges of the inner surface, and the four corners are cut off to avoid corner overlap during folding. For the aluminum plate 102, only the four corners need to be cut off, and bending is sufficient, resulting in a strong overall appearance of the decorative panel. The four sides of the panel are folded inward at 90° along the grooves to form folded edges with a height of 20-30mm. Adhesive is applied to the folded edges, which are then fixed using the first connecting corner bracket 1. The corner bracket is connected to the folded edge using self-tapping screws to ensure that the four sides form a rectangular frame, improving the overall rigidity of the panel.

[0042] The decorative panel body 100 is filled with flame-retardant materials such as expanded perlite that match the height of the folded edge.

[0043] A U-shaped reinforcing rod 3 is centrally positioned along the 100mm width of the decorative panel. The inner sides of both ends of the reinforcing rod 3 are connected to the panel's folded edge via connecting blocks 4. The connecting blocks 4 are fixed to the inner sides of the reinforcing rod 3 with screws on both sides, and to the folded edge with a self-tapping screw at one end. This design uses the reinforcing rod 3 to distribute stress in the center of the panel, preventing large panels from sagging and deforming due to their own weight.

[0044] The four folded edges of the decorative panel body 100 are connected to the mounting frame 6 on the wall 5 via corresponding Z-shaped brackets 2: one end of the Z-shaped bracket 2 is fixed to the folded edge of the panel with screws, and the other end is connected to the mounting frame 6 with screws. To avoid stress concentration and overlapping installation positions, the Z-shaped brackets 2 on opposite sides are staggered.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 lies in the connection method of the reinforcing rod 3, such as... Figure 5 As shown, the installation structure includes a first connecting bracket 1, four Z-shaped brackets 2, a U-shaped reinforcing rod 3, and a second connecting bracket 41. The specific differences are as follows:

[0047] A U-shaped reinforcing rod 3 is centrally positioned along the width of the decorative panel body (100mm). Both ends of the reinforcing rod 3 are connected to the folded edge of the panel via second connecting brackets 41. One end of the second connecting bracket 41 is fixed to the side of the reinforcing rod 3 with screws, and the other end is attached to the folded edge surface of the panel and fixed with self-tapping screws. Compared to the connecting block 4 in Embodiment 1, the second connecting bracket 41 provides a rigid connection, suitable for scenarios with higher strength requirements, and can further improve the connection strength between the reinforcing rod 3 and the panel.

[0048] The remaining specific implementation methods are the same as in Example 1, and will not be repeated here.

[0049] The plate structure of the present invention is an all-aluminum composite structure consisting of an aluminum plate, a three-dimensional aluminum core 104, and an aluminum back plate 106, combined with a flame-retardant polymer film and a non-combustible coating layer, which achieves the GB8624-2012 A2 fire protection standard. At the same time, the three-dimensional aluminum core 104 structure significantly improves the bending strength and heat insulation performance.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
