Description

Technical Field

[0001] This utility model relates to a composite wall panel with a vacuum insulation board covered by sealing mortar, belonging to the technical field of thermal insulation wall panels. Background Technology

[0002] Prefabricated wall panels can be prefabricated in a factory and transported to the site for installation, significantly improving on-site construction efficiency. Using vacuum insulation panels as the insulation core material in prefabricated wall panels achieves excellent insulation performance and significantly reduces the overall thickness and weight of the panels, thus simplifying transportation and installation. However, drilling holes in the wall panels during installation is necessary to secure them to the building structure with bolts. This drilling disrupts the vacuum seal of the insulation panels, leading to bulging and loss of their vacuum insulation properties. While some technologies divide the vacuum insulation panels into smaller vacuum units to reduce the impact of drilling on the overall insulation performance, their structure still needs improvement to ensure the overall sealing and insulation performance of the wall panels. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a composite wall panel with a vacuum insulation board covered by sealing mortar. The panel has a small thickness, and the vacuum degree of the vacuum insulation board can be effectively protected.

[0004] This utility model achieves the above objectives by adopting the following technical solutions:

[0005] A composite wall panel with a vacuum insulation board covered by sealing mortar includes a core board and a sealing mortar layer covering the six sides of the core board.

[0006] The core board is composed of a wire mesh and multiple vacuum insulation panels arranged on one side of the wire mesh, with insulation strips filling the gaps between adjacent vacuum insulation panels.

[0007] Fiberglass mesh is embedded in the sealing mortar layer on both sides parallel to the composite wall panel.

[0008] Optionally, the sealing mortar layer is formed by curing polymer cement waterproof mortar or airtight mortar.

[0009] Optionally, the insulation strip is formed by curing insulation mortar applied to the gap.

[0010] Optionally, the insulation strip is made of Class A fireproof insulation material, which is selected from any one of rock wool board, inorganic plasticized microporous insulation board, and thermosetting modified polystyrene board.

[0018] The beneficial effects of this application include, but are not limited to:

[0019] This utility model provides a composite wall panel with a sealed mortar-coated vacuum insulation panel. The core panel, formed by assembling vacuum insulation panels, serves as the intermediate insulation layer, reducing the overall thickness of the composite wall panel. The six sides of the core panel are protected by a sealed mortar layer, preventing damage to the vacuum level of the vacuum insulation panels. Since the core panel is composed of multiple vacuum insulation panels, even if the vacuum level of a single panel is damaged, only a small area is affected, minimizing the impact on the overall insulation performance of the core panel. The perforations on the composite wall panel are located at the seams, further minimizing any significant impact on the overall vacuum level of the vacuum insulation panels.

[0030] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0031] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, the composite wall panel with a vacuum insulation board covered by sealing mortar provided by this utility model includes a core board 100 and a sealing mortar layer 200 covering the six sides of the core board 100. Fiberglass mesh 300 is embedded in the sealing mortar layer 200 on both sides parallel to the wall surface of the composite wall panel. The fiberglass mesh 300 can prevent the sealing mortar layer 200 from cracking. The wall surface of the composite wall panel refers to the wall surface formed during the installation of the wall panel. Figure 1 The direction parallel to the paper is the wall direction.

[0033] The core board 100 is composed of a wire mesh 110 and multiple vacuum insulation panels 120 arranged on one side of the wire mesh 110. The gaps between adjacent vacuum insulation panels 120 are filled with insulation strips 130.

[0034] The composite wall panel provided by this utility model uses a core panel 100, formed by assembling vacuum insulation panels 120, as the intermediate insulation layer, thus reducing the overall thickness of the composite wall panel. The six sides of the core panel 100 are protected by sealing mortar to prevent damage to the vacuum level of the vacuum insulation panels 120. Since the core panel 100 is composed of multiple vacuum insulation panels 120, even if the vacuum level of a single vacuum insulation panel 120 is damaged, only a small area is affected, resulting in minimal impact on the overall insulation performance of the core panel 100.

[0035] Typically, the size of vacuum insulation panels 120 is 10cm-60cm, and the thickness is 2-4cm. For example, vacuum insulation panels 120 with dimensions of 30cm×40cm, 20cm×40cm, 20cm×30cm, 58cm×20cm, and 58cm×30cm can be used.

[0036] Specifically, the sealing mortar layer 200 is formed by curing polymer cement waterproof mortar or airtight mortar. The polymer cement waterproof mortar or airtight mortar is a commercially available product. The principle of airtightness in airtight mortar is the same as that in airtight concrete, which is made by adding an airtight agent to the substrate.

[0037] The spacer joints can be filled with insulating mortar, which cures to form insulating strips 130. Alternatively, Class A fireproof insulation material cut into strips can be filled into the spacer joints. Class A fireproof insulation material can be selected from any one of rock wool board, inorganic plasticized microporous insulation board, or thermosetting modified polystyrene board.

[0038] In one embodiment, the various vacuum insulation panels 120 on the core board 100 are bonded to the wire mesh 110 by adhesive.

[0039] In another embodiment, each vacuum insulation panel 120 is connected to a wire mesh 110 via a connector 140, preferably a galvanized wire mesh 110.

[0040] Specifically, such as Figures 3-5 As shown, the connector 140 is an L-shaped component, a T-shaped component, a cross-shaped component, or a long strip component, preferably a steel component.

[0041] like Figure 6 and Figure 7 As shown, when using L-shaped, T-shaped, or cross-shaped components, one right-angled side of the component is welded to the wire mesh 110, and the other right-angled side presses against the surface of the vacuum insulation panel 120 away from the wire mesh 110. When using a T-shaped component, the two ends of its right-angled side can press against two adjacent vacuum insulation panels.

[0042] like Figure 8As shown, when a long strip component is used, one end of the component is welded to the wire mesh 110, and the other end is inclined and pressed against the surface of the vacuum insulation plate 120 away from the wire mesh 110.

[0043] The production method of the composite wall panel with sealed mortar-coated vacuum insulation board provided by this utility model is as follows:

[0044] (1) Determine the size and quantity of the vacuum insulation panel 120 according to the size of the composite wall panel, fix the vacuum insulation panel 120 on the wire mesh 110 to make the core panel 100.

[0045] (2) Apply a layer of waterproof and airtight mortar to the bottom of the mold, and press a 300mm fiberglass mesh into the waterproof and airtight mortar.

[0046] (3) Lay the core board 100 on the waterproof and airtight mortar layer inside the mold;

[0047] (4) Apply waterproof and airtight mortar to the top of the core board 100 and press fiberglass mesh 300 into the waterproof and airtight mortar layer.

[0048] (5) Curing and solidification to form the composite wall panel of the vacuum insulation board covered by the sealing mortar provided by this utility model.

[0049] To fill the gap between adjacent vacuum insulation panels 120, insulation strips 130 can be filled into the gap in step (1); or insulation slurry can be brushed into the gap in step (3) to form insulation strips 130.

[0050] Furthermore, pre-drilled holes can be formed at the joint areas; alternatively, markings can be placed on the composite wall panel surface at the corresponding joint areas to facilitate later identification of the joints for drilling. This way, the drilling positions are placed within the joints, avoiding disruption of the vacuum insulation panel's vacuum level.

[0051] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] Any aspects of this utility model not described in detail are known to those skilled in the art.
