Description

Technical Field

[0001] The utility model relates to a high-strength vacuum heat-insulating wallboard, belonging to the technical field of building materials. Background Art

[0002] Prefabricated wall panels are prefabricated in factories through mechanized and automated production lines and then transported to the site for installation and use. This offers significant advantages in on-site construction efficiency. To improve the thermal insulation and lightweight properties of prefabricated wall panels, some technologies use vacuum insulation panels as the insulation core material. However, if the vacuum level of the vacuum insulation panel is disrupted during installation, such as by drilling and fixing operations, this can cause bulging of the panel, resulting in loss of vacuum insulation performance and failure. To address this issue, some technologies divide the vacuum insulation panel into small vacuum cells to reduce the impact of drilling on the panel's overall insulation performance. However, vacuum insulation panels composed of vacuum cells have poor rigidity, and their direct application in prefabricated wall panels can result in insufficient panel strength.

[0014] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0015] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways other than those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figure 1 As shown in the figure, the high-strength vacuum insulation wall panel provided by the utility model includes a bearing plate 100, an interface agent layer 200, a bonding mortar layer 300, a vacuum insulation core board 400, a thermal insulation mortar layer 500 and a finishing mortar layer 600 arranged in sequence, and a steel mesh 700 is embedded in the bonding mortar layer and the thermal insulation mortar layer respectively.

[0017] The vacuum insulation core panel 400 is formed by arranging a plurality of vacuum core panel units. The specific structure may adopt the vacuum insulation panel structure provided in the patents CN221567512U, CN221372539U, and CN220704808U filed by the present applicant. The purpose of using a vacuum insulation core panel is to reduce the insulation thickness. Furthermore, the combined structure of the vacuum core panel units ensures that only a small area of ​​the vacuum insulation core panel is destroyed during drilling, thereby ensuring the overall vacuum insulation performance of the vacuum insulation core panel. Typically, the side length of the vacuum core panel unit is 5-10 cm.

[0018] The vacuum insulation core panel formed by arranging vacuum core panel units is easy to bend and deform at the joints. For this reason, the utility model arranges steel wire meshes on both sides of the vacuum insulation core panel, sandwiches the vacuum insulation core panel between the steel wire meshes, and adds a rigid bearing plate on the basis of arranging each mortar layer, thereby improving the strength of the insulation wall panel.

[0019] Typically, the load-bearing board is a cement-based fiberboard or a calcium silicate board.

[0020] In one specific embodiment, the thicknesses of the bearing board, the bonding mortar layer, the vacuum insulation core board, the thermal insulation mortar layer and the plastering mortar layer are 4-5 mm, 3-4 mm, 20-30 mm, 20-30 mm and 3-4 mm respectively.

[0021] Among them, each mortar layer forms a composite connection with the corresponding functional layer through slurry coating and solidification.

[0022] During production, the following steps can be followed: first, lay the calcium silicate board and spray the interface agent on the top of the calcium silicate board; then, roll-coat the bonding mortar; thereafter, lay the insulation board sandwiched between two steel wire meshes on the top of the bonding mortar; then roll-coat the insulation mortar and the finishing mortar, solidify the slurry into shape, and maintain it to form the high-strength vacuum insulation wall panel.

[0023] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the utility model.
