DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0029] As Figures 1-3 shown, the present invention discloses an integrated thermal insulation and decorative panel, which includes three layers of structures: a decorative surface layer 100, a substrate layer 200, and a thermal insulation layer 300, and N riveting parts 400. It also includes an adhesive layer (not shown) provided between each layer to provide adhesion. Among them, the decorative surface layer 100, the substrate layer 200, and the thermal insulation layer 300 are stacked in sequence from top to bottom, and are bonded and compounded into one body through the corresponding adhesive layers. Each adhesive layer used is independently made of commonly used polyurethane glue or PUR glue or other glue materials in the art.

[0030] There are M first accommodating through-holes 210 vertically formed on the substrate layer 200. Each of the first accommodating through-holes 210 is evenly arranged and penetrates through the upper and lower surfaces of the substrate layer 200. There are N second accommodating through-holes 310 vertically formed on the heat insulation layer 300. Both M and N are positive integers, and M≥N. The second accommodating through-holes 310 are arranged directly below the first accommodating through-holes 210 and are in one-to-one communication with the first accommodating through-holes 210 directly above them. The provided first accommodating through-holes 210 have the functions of glue discharging and exhaust / gas discharging, and in combination with the second accommodating through-holes 310, they can assist the riveting member 400 in riveting.

[0031] In terms of glue discharging, by utilizing the internal space of the first accommodating through-holes 210, when the decorative surface layer 100 and the substrate layer 200 are adhesively bonded and compounded, the excess glue between the layers can be led out and accommodated, avoiding the phenomenon of uneven accumulation of the glue layer between the layers, ensuring that the glue layer between the layers is flat and uniform, effectively improving defects such as incomplete curing due to excessive glue layer thickness in some areas, voids due to insufficient glue in some areas, and local stress concentration after the glue layer is cured, thereby avoiding the occurrence of hollowing and delamination of the decorative surface layer 100 after adhesive bonding and compounding, and ensuring the firm adhesion of the decorative surface layer 100. Moreover, the glue discharged into the first accommodating through-holes 210 can further enhance the adhesive strength between the decorative surface layer 100 and the substrate layer 200 after curing, further improving the mechanical properties and use safety of the thermal insulation decorative integrated board.

[0032] Similarly, in terms of exhaust / gas discharging, by utilizing the internal space of the first accommodating through-holes 210, the gas generated during the drying of the glue layer can be led out, avoiding the gas remaining between the interfaces of the decorative surface layer 100 and the substrate layer 200, which may cause bulging after adhesive bonding and compounding. It can also discharge the moisture between the layers, solving the problem of warping deformation of the board caused by inconsistent moisture content of the contact surface and open surface between the decorative surface layer 100 and the substrate layer 200 during compounding.

[0033] In terms of assisting riveting, the above-mentioned riveting member 400 does not need to be additionally drilled and can be directly inserted into the upper and lower paired and communicating first accommodating through-holes 210 and second accommodating through-holes 310, thereby riveting and fixing the substrate layer 200 and the heat insulation layer 300 together, effectively improving the connection strength between the substrate layer 200 and the heat insulation layer 300 and enhancing the structural stability of the thermal insulation decorative integrated board.

[0034] The riveting member 400 is a press riveting connector or a blind riveting connector. It is made of a non-metallic material, has high connection strength, is easy to install, and has a low thermal conductivity coefficient, having little impact on the overall thermal insulation performance. In this embodiment, the riveting member 400 can be made of PP material, which is resistant to strong acids and alkalis, has a low cost, and is beneficial to the lightweight of the board, or made of nylon material, which has higher strength and better high and low temperature performance.

[0035] The riveting part 400 includes a sleeve 410 and an inner bolt 420. The sleeve 410 is vertically inserted into the first accommodation through-hole 210 and the second accommodation through-hole 310. The upper part of the sleeve 410 is a valve flap structure 411. The inner bolt 420 is inserted into the sleeve 410. The upper part of the inner bolt 420 presses against the valve flap structure 111, thereby expanding and expanding the valve flap structure 111 and expanding it in the first accommodation through-hole 210 to achieve the purpose of riveting and fixing.

[0036] In this embodiment, the outer diameter of the sleeve 410 is about 6 mm. In one case, the sleeve 410 is internally threaded. The inner bolt 420 can be a self-tapping screw. When locking with the sleeve 410, the upper part of the inner bolt 420 expands the valve flap structure 111, and the lower part of the inner bolt 420 abuts against the lower end orifice of the second accommodation through-hole 210.

[0037] To match the riveting part 400, the first accommodation through-hole 210 is a tapered hole, and the second accommodation through-hole 310 is vertically connected directly below the first accommodation through-hole 210. The aperture of the large-hole end of the first accommodation through-hole 210 is 7 - 8 mm, and the aperture of the small-hole end is 6 - 7 mm. Moreover, the large-hole end of the first accommodation through-hole 210 faces the decorative surface layer 100, which can accelerate the glue discharge speed at the interface of the decorative surface layer 100.

[0038] In another case, as Figures 4-5 shown, the riveting part 400 further includes a plurality of sliding pieces 440. The sliding pieces 440 are vertically fixed on the side wall of the inner bolt 420, and a part of the sliding pieces 440 extends to the outside of the sleeve 410 through the gap of the valve flap structure 111. By using the extended sliding pieces 440, the friction force between the riveting part 400 and the thermal insulation layer 300 can be enhanced, playing a role in enhancing the fixation.

[0039] At this time, the upper part of the inner bolt 420 is in a conical shape with a larger upper part and a smaller lower part. The lower part of the inner bolt 420 is provided with a threaded hole, and a matching bolt fastener 430 is provided below. After the fastener 430 is locked into the inner bolt 420, it can pull the inner bolt 420 downward, thereby expanding the valve flap structure 111 and ensuring the flatness of the lower side of the thermal insulation layer 300.

[0040] In addition, to improve the overall strength of the board, the integrated thermal insulation and decoration board is further provided with a back plate layer 500. The back plate layer 500 is adhesively bonded and compounded on the lower side of the thermal insulation layer 300. Correspondingly, the riveting part 400 is vertically arranged between the decorative surface layer 100 and the back plate layer 500. A plurality of back holes 510 are formed on the lower side surface of the back plate layer 500. By using the back holes 510, adhesives and mortar can be squeezed in during the installation of the integrated board, enhancing the bonding strength between the back side of the integrated board and the installation surface, and exhausting steam during the curing of the adhesives and mortar to avoid water vapor accumulation.

[0041] The back hole 510 is preferably a tapered hole. The aperture of the large-hole end is 8-10 mm, and the aperture of the small-hole end is 6-8 mm. The large-hole end of the back hole 510 faces the thermal insulation layer 300, and a barb structure can be formed after the adhesive and mortar are cured, resulting in a better bonding effect. The position of the back hole 510 is staggered up and down with the position of the second accommodation through hole 310, which can avoid stress concentration and make the stress more evenly distributed in the entire integrated board structure.

[0042] When preparing the thermal insulation and decoration integrated board, the decorative surface layer 100 and the substrate layer 200 are usually compounded first, and then the thermal insulation layer 300 and the back plate layer 500 are compounded. Among the various layer structures, the decorative surface layer 100 is preferably an aluminum color layer, which has rich colors and good color brightness. It can also be an aluminum-plastic board layer, which has strong decoration and light weight, or a stainless steel layer, which has strong weather resistance and good impact resistance. The thickness T1 of the decorative surface layer 100 is 0.3-0.6 mm. An electrostatic film layer 600 is attached to the upper side of the decorative surface layer 100, which can reduce the scratches and abrasions of the decorative surface layer 100 during production, transportation, processing, and installation, and avoid the risk of residual glue on the board surface.

[0043] The substrate layer 200 is selected as a steam-pressed calcium silicate board layer, which has higher flexural and tensile strength and durability compared with ordinary calcium silicate boards, and can compensate for the influence of the internal porous structure on the strength and wind pressure resistance of the integrated board. The thickness T2 of the substrate layer 200 is about 8-10 mm.

[0044] The thickness T3 of the thermal insulation layer 300 is 30-120 mm. In the case where the back plate layer 500 is provided, the thermal insulation layer 300 can be selected as a rock wool thermal insulation layer to make the integrated board meet the energy-saving and insulation requirements and A-level fire protection requirements of different buildings. In the case where the back plate layer 500 is not provided, the thermal insulation layer 300 is preferably an A2-level thermosetting board layer or an EPS (polystyrene board) layer.

[0045] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in form and detail without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the protection scope of the present invention.
