Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, and in particular to a UHPC double-sided one-time formed thermal insulation and decorative integrated wall 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] Currently, most of the ultra-high performance concrete (UHPC) decorative panels on the market are single-sided panels with embedded insulation materials, so the indoor part still needs secondary decoration to cover the exposed part. The limitations of existing technologies are mainly manifested in:

[0004] 1. Using UHPC panels with embedded insulation materials to make wall panels can only achieve a single-sided molding effect. The insulation material on the back of the product is exposed, and the indoor part still needs secondary decoration, which increases material usage and on-site construction time.

[0005] 2. The UHPC wall panels in modular house construction need to be formed in one step, but the existing prefabricated single panels have certain weaknesses in various indicators such as weight, strength, sound insulation, and thermal insulation. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a UHPC double-sided one-time formed thermal insulation and decorative integrated wall panel, which overcomes the shortcomings of the prior art and has a reasonable design. A sealed film is used to seal and coat the outer surface of the thermal insulation and sound insulation cotton to prevent the thermal insulation and sound insulation cotton from absorbing moisture in the UHPC premix; thereby ensuring the strength and surface texture of the UHPC board.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A UHPC double-sided one-time formed thermal insulation and decorative integrated wall panel comprises an upper UHPC panel and a lower UHPC panel cast in upper and lower layers, wherein the upper UHPC panel and the lower UHPC panel are fixedly connected, and a closed cavity is formed between the upper UHPC panel and the lower UHPC panel, wherein thermal insulation and sound insulation cotton is arranged in the cavity, and the outer surface of the thermal insulation and sound insulation cotton is covered with a closed film.

[0009] Preferably, the thickness of the upper UHPC board and the lower UHPC board are both 20-30 mm, and the total thickness of the wallboard is 100-240 mm.

[0010] Preferably, a plurality of reinforcing ribs are provided between the upper UHPC panel and the lower UHPC panel, and the reinforcing ribs are connected to the upper UHPC panel and the lower UHPC panel.

[0011] Preferably, the reinforcing ribs are arranged in a grid shape, and the reinforcing ribs divide the cavity into a plurality of small cavities. A plurality of thermal insulation and sound insulation cottons are provided, and each thermal insulation and sound insulation cotton is filled in a small cavity respectively.

[0012] Preferably, a plurality of pre-embedded connectors are evenly embedded around the outer edges between the upper UHPC board and the lower UHPC board.

[0013] The utility model provides a UHPC double-sided one-time formed thermal insulation and decorative integrated wall panel. It has the following beneficial effects: the thermal insulation and sound insulation cotton can be completely buried between the upper UHPC board and the lower UHPC board by pouring. It meets the requirements of the building for thermal insulation and sound insulation. At the same time, it also avoids the secondary decoration of the indoor wall panels and reduces the project cost. In addition, by using a sealed film to seal and coat the outer surface of the thermal insulation and sound insulation cotton, the thermal insulation and sound insulation cotton itself is separated from the upper UHPC board and the lower UHPC board, thereby effectively preventing the thermal insulation and sound insulation cotton from absorbing moisture in the UHPC premix; thereby ensuring the strength and surface texture of the UHPC board. This also reduces the waste of materials during the construction process. BRIEF DESCRIPTION OF THE DRAWINGS
