Description

Technical Field

[0001] The invention belongs to the technical field of aluminum composite panels, and in particular relates to a high-strength glass decorative surface aluminum composite panel. Background Art

[0002] Aluminum-based composite panels are new types of panels with an aluminum honeycomb core or aluminum foam composite sheet as the base material, and a PVC film, wood veneer, stone, cloth texture, leather, and other finishes on the aluminum surface. These panels offer high overall and local toughness, are flat and large, and resist warping and deformation. They are also lightweight, corrosion-resistant, flame-retardant, and environmentally friendly. The thin film layer itself has no effect on the panel's weight or performance (including fire resistance), and the material itself contains no harmful volatiles such as formaldehyde.

[0003] Aluminum composite panels are often used as ceilings, and a decorative surface is often composited on the lower surface of the panel, but the decorative effect is simple. In order to improve the decorative effect, a glass decorative surface with better decorative effect can be set under the aluminum composite panel. However, the existing glass and aluminum composite panels have different thermal expansion coefficients. After experiencing multiple thermal expansion and contraction, debonding and cracking are prone to occur, resulting in lower strength of the aluminum composite panel with glass decorative surface. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-strength glass decorative aluminum composite panel with adaptive thermal expansion and contraction in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A high-strength glass-decorative aluminum composite panel includes a ceiling assembly and a frame assembly for installing the ceiling assembly. The ceiling assembly includes, from top to bottom, an aluminum base plate, a honeycomb panel, and an aluminum panel. The honeycomb panel is provided with an active cavity inside, and the surface of the aluminum panel is provided with an active groove corresponding to the active cavity. Several connecting pieces with horizontal freedom are provided through the interior of the active cavity and the active groove. The bottom ends of several of the connecting pieces are provided with patterned decorative panels, and the bottom end surfaces of several of the patterned decorative panels are adhered to glass decorative panels by colloid.

[0007] As a further optimization scheme of the present invention, the frame assembly includes a hanger for hanging at the lower end of the roof, a frame arranged at the bottom end of the hanger, and a hanger for connecting the frame and the hanger. The hanger, hanger and frame are common ceiling installation methods in this field.

[0008] As a further optimization solution of the present invention, the difference between the thermal expansion coefficient of the patterned decorative plate and the thermal expansion coefficient of the glass decorative plate is less than 10%, which can effectively protect the colloid at the adhesion point between the patterned decorative plate and the glass decorative plate.

[0009] As a further optimization solution of the present invention, the material of the patterned decorative plate is wood. The thermal expansion coefficient of wood is slightly different from that of glass, and the surface of the wood has a good decorative effect. The aesthetics can be greatly improved by bonding.

[0010] As a further optimization scheme of the present invention, the connecting part includes a clamping block located inside the movable cavity, a threaded rod threadedly connected to the clamping block and passing through the movable groove, and a connecting base fixedly connected to the bottom end of the threaded rod. The connecting base is fixedly connected to the patterned decorative plate. The purpose of setting the clamping block is to tightly fix the patterned decorative plate under the aluminum panel. During thermal expansion and contraction, due to the different thermal expansion coefficients of the aluminum-based ceiling assembly and the glass decorative panel, their thermal expansion amplitudes are also different. In order to prevent debonding, bending, cracking and other problems caused by thermal expansion and cooling, the connecting base and the clamping block move horizontally along the movable groove and the movable cavity respectively.

[0011] As a further optimization scheme of the present invention, the surfaces of the clamping block and the connecting base in contact with the aluminum panel are all provided with ball holes, and spherical balls in contact with the aluminum panel are provided in the ball holes. The spherical balls are provided to reduce the friction of the connecting base and the clamping block when they move horizontally along the movable groove and the movable cavity respectively.

[0012] As a further optimization solution of the present invention, a groove is provided on the surface of the patterned decorative plate, and the connecting base and the groove are fixed by bonding with a first connecting glue. This fixing method does not require perforation under the patterned decorative plate and has a good aesthetic effect.

[0013] As a further optimization solution of the present invention, the upper surface of the clamping block is provided with a cross groove for easy disassembly and assembly, and the surface of the aluminum substrate is provided with a top hole for disassembly and assembly of the clamping block. The provision of the cross groove can facilitate the disassembly and assembly of the clamping block.

[0014] As a further optimization solution of the present invention, the patterned decorative plate and the glass decorative plate are bonded to each other without bubbles by a second connecting glue, and the second connecting glue is a colorless and transparent thermal colloid, which improves the aesthetics.

[0015] The beneficial effects of the present invention are:

[0016] The present invention provides a connector with lateral freedom and a patterned decorative plate with a thermal expansion coefficient similar to that of the glass decorative panel, so that a glass decorative panel with a better decorative effect can be combined with an aluminum-based ceiling. When thermal expansion and contraction occur, the connector slides along a movable cavity and a movable groove provided inside the aluminum-based ceiling, so that the stress generated by thermal expansion disappears, which can prevent debonding and cracking. The glass decorative panel has good strength while being beautiful. In addition, the entire surface of the glass decorative panel is bonded by a second connecting adhesive, which further improves the strength of the glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figure 1-7As shown, a high-strength glass-decorative aluminum composite panel includes a ceiling component 2 and a frame component 1 for installing the ceiling component 2. The ceiling component 2 includes an aluminum base plate 21, a honeycomb panel 22 and an aluminum panel 23 from top to bottom. Four groups of sixteen active cavities 25 are opened inside the honeycomb panel 22. Active grooves 26 corresponding to the active cavities 25 are opened on the surface of the aluminum panel 23. Connectors 3 with horizontal freedom are arranged through the active cavities 25 and the active grooves 26. A patterned decorative plate 41 is provided at the bottom end of every four connectors 3. The bottom end surface of every four patterned decorative plates 41 is bonded to a glass decorative plate 45 by a colloid. The patterned decorative plate 41 and the glass decorative plate 45 are bonded to each other without bubbles by a second connecting glue 44. The second connecting glue 44 is a colorless and transparent thermal glue.

[0029] When thermal expansion and contraction occur, since the thermal expansion coefficient of the aluminum ceiling assembly 2 is greater than that of the glass decorative panel 45, in order to solve the problems of debonding and cracking caused by different thermal expansion amplitudes, the glass decorative panel 45 is connected to the ceiling 2 assembly through a connector 3 with horizontal freedom, wherein the directions of the movable cavity 25 and the movable groove 26 are set according to the trajectory of relative thermal expansion, so that when the aluminum-based ceiling assembly 2 expands, the connector 3 moves horizontally along the movable cavity 25 and the movable groove 26 to reduce the impact of thermal expansion and contraction on the patterned decorative panel 41 and the glass decorative panel 45.

[0030] The frame assembly 1 includes a hanger 11 for hanging at the lower end of the roof, a frame 13 arranged at the bottom end of the hanger 11, and a hanger 12 for connecting the frame 13 and the hanger 11. The frame assembly 1 is a common ceiling suspension method. The width of the aluminum substrate 21 is larger than the size of the frame 13 to achieve the purpose of installing the ceiling assembly 2.

[0031] In order to prevent the second connecting glue 44 from debonding, the difference in thermal expansion coefficient between the patterned decorative plate 41 and the glass decorative plate 45 is less than 10%. The two materials with the same thermal expansion coefficient are bonded together through the transparent second connecting glue 44, which can effectively improve the strength of the glass decorative plate 45 and will not cause debonding and cracking.

[0032] As a preferred solution, the material of the patterned decorative plate 41 is wood.

[0033] In order to further improve the production and installation of the connection 3, the connection part 3 is configured to be detachable. The connection part 3 includes a clamping block 33 located inside the movable cavity 25, a threaded rod 32 threadedly connected to the clamping block 33 and passing through the movable groove 26, and a connecting base 31 fixedly connected to the bottom end of the threaded rod 32. The connecting base 31 is fixedly connected to the patterned decorative plate 41. The upper surface of the clamping block 33 is provided with a cross groove 35 for easy disassembly and assembly, and the surface of the aluminum substrate 21 is provided with a top hole 24 for disassembling and assembling the clamping block 33.

[0034] During use, the clamping block 33 is tightened so that the clamping block 33 and the connecting base 31 clamp the aluminum panel 23 to each other, so as to achieve the purpose of stabilizing the patterned decorative plate 41. However, this mutually clamping installation method makes the connecting part 3 have a low degree of freedom to slide along the movable cavity 25 and the movable groove 26 during thermal expansion and contraction. In order to solve this problem, the surfaces of the clamping block 33 and the connecting base 31 that contact the aluminum panel 23 are all provided with ball holes 36, and the ball holes 36 are each provided with spherical balls 37 that contact the aluminum panel 23.

[0035] A groove 42 is provided on the surface of the patterned decorative plate 41, and the connecting base 31 and the groove 42 are bonded and fixed by a first connecting glue 43. This connection method between the patterned decorative plate 41 and the connecting base 31 keeps the lower surface of the patterned decorative plate 41 intact, thereby improving the aesthetics.

[0036] Example 2

[0037] like Figure 8 As shown, unlike Example 1, the patterned decorative panels 41 are provided in nine pieces, and the bottom ends of the nine patterned decorative panels 41 are simultaneously adhered to a glass decorative panel 45 through a second connecting glue 44. In Example 1, each patterned decorative panel 41 is connected to the ceiling assembly 2 through four connecting members 3, while in Example 2, each patterned decorative panel 41 can be provided with only one or two connecting members 3. It should be noted that the positions of the connecting members 3 are different, and the directions of the corresponding active cavities 25 and active grooves 26 are also different, which needs to be obtained by modeling and calculating the movement trajectory of the connecting members 3 relative to the ceiling assembly 2 during thermal expansion and cooling.

[0038] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
