Description

Technical Field

[0001] The utility model relates to the technical field of box panels, in particular to a cold bridge-proof stepped box panel. Background Art

[0002] Anti-cold bridge stepped box panels are a structural design used in buildings or projects to prevent heat conduction. Cold bridges refer to areas in buildings or structures that easily conduct heat, resulting in energy loss and poor temperature regulation. The design of the box panels is intended to reduce or eliminate this cold bridge effect.

[0003] For example, the Chinese patent announcement number (CN201731597U) discloses an air conditioner anti-cold bridge box panel with a simpler structure and better heat insulation effect, which includes an inner panel and an outer panel, and the connection between the inner panel and the outer panel is sealed together by an insulating strip, and the inner panel and the outer panel are filled with insulation material, wherein the inner panel and the outer panel are made of steel plates, the insulating strip can cover the side of the connection between the inner panel and the outer panel, and the strip has a special cross-section, and its shape can be embedded in the gap between the inner panel, the strip and the outer panel, which can ensure the sealing between the inner panel, the strip and the outer panel to prevent air leakage, and the insulation material adopts fluorine-free environmentally friendly hard polyurethane or glass fiber composite board, which can achieve a certain heat insulation and sound insulation effect. The box panel of the utility model is adhered with an insulating strip at the connection between the inner panel and the outer panel, which can effectively solve the local cold bridge phenomenon.

[0004] However, the above-mentioned patent still has the problem of poor effect in eliminating cold bridges for box panels. For example, in the above-mentioned patent, insulation strips are adhered at the connection between the inner panel and the outer panel to solve the local cold bridge phenomenon. However, the box panels in this method are straight panels, which have a poor effect in interrupting the conduction of heat and are inconvenient to effectively isolate or slow down heat conduction, resulting in poor effect in eliminating the cold bridge phenomenon for the box panels.

[0006] To achieve the above object, the utility model provides the following technical solutions: an anti-cold bridge stepped box panel, comprising an anti-cold bridge aluminum alloy frame, an anti-cold bridge component is provided on the outer side of the anti-cold bridge aluminum alloy frame;

[0007] The anti-cold bridge component includes a stepped outer panel, a stepped inner panel, a connecting material strip, a foam layer, a self-tapping screw and a sealing strip.

The stepped structure is used to prevent heat conduction, which can effectively interrupt the heat conduction path, slow down the loss of hot and cold energy, and provide thermal insulation and heat preservation effects. The foaming material usually has a low thermal conductivity and can effectively slow down the conduction of heat. By forming a layer of insulating material between the stepped outer panel 21 and the stepped inner panel 22, the heat conduction path is blocked, which can effectively prevent or slow down the occurrence of the cold bridge effect. The stepped outer panel 21 and the stepped inner panel 22 are combined and installed using the anti-cold bridge aluminum alloy frame 1 and the self-tapping screws 25. The support ribs 28 coated with insulating material are used at key positions in the foaming layer 24 to slow down heat conduction and provide structural strength and support to the foaming layer 24. At the same time, the foaming layer 24 is wrapped to reduce the cold bridge effect. The sealing strip 26 and the connecting material strip 23 are arranged between the frames to form an effective insulation layer during installation. Sealing and connection are very critical, which can reduce the penetration of air and moisture, thereby improving insulation performance.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0029] If this patent discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection can also be replaced by an integrated structure (for example, manufactured by a casting process) (except where it is obviously impossible to use an integrated forming process).
