Description

Technical Field

[0001] The utility model relates to the technical field of decorative panels, in particular to a UHPC honeycomb aluminum plate composite decorative panel. Background Art

[0002] As the most widely used building material, concrete is closely related to people's daily life. As people's requirements for concrete performance become higher and higher, a new type of ultra-high performance concrete (UHPC) has been developed, which has ultra-high strength and excellent durability. With its excellent performance, ultra-high performance concrete has been widely used in engineering projects with harsh construction and service environments such as marine and nuclear power in the past 20 years. UHPC decorative panels have received widespread attention and application in the field of building assembly technology.

[0003] In the current existing technology, pure UHPC boards are usually used as decorative panels. In addition to meeting the mechanical performance indicators such as compression and flexural strength, low water absorption, and stain and corrosion resistance required by the specifications, it is generally required that the thickness of the UHPC board should not be too thick or too heavy, usually with a thickness of 20mm-50mm, and the board width should be as large as possible.

[0004] However, since UHPC panels are relatively thick and heavy, more raw materials are needed during production and maintenance, and the maintenance cycle is long. Excessively thick panels directly lead to heavier weight, large consumption of raw materials, and inconvenient on-site construction due to the thickness of the panels. It is also relatively limited when used as a suspended ceiling. In addition, due to material and production process reasons, UHPC usually has certain shrinkage and warping deformation. When the thickness of the panel is certain, the flatness is not high, resulting in limited panel size. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0024] Embodiment 1, as Figure 1-4As shown, a UHPC honeycomb aluminum composite decorative panel includes a UHPC decorative panel 1 and a honeycomb aluminum panel 2, wherein the UHPC decorative panel 1 and the honeycomb aluminum panel 2 are bonded and fixed to each other via a bonding layer 3; in this embodiment, the thickness of the UHPC decorative panel 1 is set to 8 mm, and the thickness of the honeycomb aluminum panel 2 is set to 20 mm. The bonding layer 3 is polyurethane glue.

[0025] The honeycomb aluminum panel 2 includes a panel 21, an aluminum honeycomb core 22 and a bottom plate 23. The panel 21 and the bottom plate 23 are respectively fixedly connected to the upper surface and the lower surface of the aluminum honeycomb core 22.

The outer edges of the panel 21 and the bottom plate 23 are both provided with a 90-degree folded edge 24. The panel 21 and the bottom plate 23 are formed with the edge 24 to form a closed box structure.

[0026] Working principle:

[0027] By using the bonding layer 3 to bond the UHPC decorative panel 1 and the honeycomb aluminum panel 2 to each other, compared with the UHPC panels or stones of the same thickness, the dead weight of the panels can be greatly reduced, the use, production and maintenance of cement-based raw materials can be reduced, energy conservation and emission reduction can be achieved, and environmental protection can be achieved; and the honeycomb aluminum panel 2 itself is connected through the panel 21, the aluminum honeycomb core 22 and the bottom plate 23, and the outer circumference is wrapped 24 to form a closed box structure, so that the high flatness of the honeycomb aluminum panel 2 can be fully utilized to effectively solve the impact of shrinkage and warping deformation of the UHPC decorative panel 1, while retaining the decorativeness and durability of the original texture of the UHPC decorative panel 1, and under the same thickness, the panel width can be made larger. In addition, the entire decorative panel is lighter, which greatly reduces the load on the main structure of the building, and at the same time reduces and optimizes the use of the main structure keel, saving costs, and also brings convenience to transportation and on-site construction.

[0028] In addition, since a layer of honeycomb aluminum plate 2 is compounded on the back of the UHPC decorative plate 1, the honeycomb aluminum plate 2 can also be used as a template for marking and positioning during the production process, which can greatly improve production efficiency, especially when the specifications of the plates are different.

After the UHPC decorative panel 1 is cured and solidified, the bent section of the L-shaped metal connecting piece 4 can be fastened and connected to the honeycomb aluminum panel 2 by self-tapping screws 5, thereby further ensuring the reliability of the connection between the UHPC decorative panel 1 and the honeycomb aluminum panel 2, thereby expanding the application range of the panel.

The upper plate 72 is used to realize the connection and fixation between the sleeve 7 and the UHPC decorative plate 1, and the limiting ring 73 is arranged at the outer edge of the lower surface of the upper plate 72, so that the limiting ring 73 can be buried in the silicone structural adhesive 8, thereby effectively ensuring the overall stability of the sleeve 7, and preventing the sleeve 7 from directly sliding out of the honeycomb aluminum plate 2 during use.
