Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, specifically a metal composite wall panel. Background Technology

[0002] Metal composite wall panels are wall decoration panels that combine multiple metal materials. They typically consist of one layer of metal covered with another, aiming to save resources and reduce costs without compromising performance. However, current metal composite wall panels have some shortcomings. Assembly is mostly done by welding, which, while providing a relatively stable connection, makes disassembly inconvenient. After long-term use, if the thermal insulation and sound insulation performance deteriorates due to aging, it becomes difficult to replace the internal insulation and sound insulation materials. Furthermore, they are heavy, and when installing pipelines, additional pipe trenches or exposed pipe installations are required. The former is cumbersome, while the latter affects aesthetics. To address these issues, the inventor has proposed a metal composite wall panel to solve these problems. Utility Model Content

[0003] To address the problems of existing metal composite wall panels, such as their large overall weight, difficulty in replacing internal insulation and soundproofing materials, and inconvenience in pipeline installation, the purpose of this utility model is to provide a metal composite wall panel.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a metal composite wall panel, comprising an outer metal panel and an inner metal panel, wherein an intermediate functional layer is provided between the outer metal panel and the inner metal panel, the intermediate functional layer comprising a thermal insulation material layer and a sound insulation material layer, decorative panels being detachably provided on the sidewalls of both the outer metal panel and the inner metal panel, a transverse connector being fixedly connected to the side of the outer metal panel facing the inner metal panel, an external thread being provided at one end of the sidewall of the transverse connector, the transverse connector penetrating through the thermal insulation material layer and the sound insulation material layer, a stepped groove being provided on the side of the inner metal panel facing away from the outer metal panel, one end of the transverse connector extending into the stepped groove, and a threaded cap being provided on one side of the inner metal panel, the threaded cap corresponding to and cooperating with the external thread, and the threaded cap cooperating with the large opening of the stepped groove.

[0005] Preferably, the side of the thermal insulation material layer facing the sound insulation material layer is coated with an adhesive, and the side of the adhesive facing away from the thermal insulation material layer is bonded and fixed to the sound insulation material layer. The thermal insulation material layer can be made of rock wool, and the sound insulation material layer can be made of damping felt. The two are bonded and fixed together by the adhesive. Polyurethane adhesive can be used as the adhesive. The adhesive is an existing, mature, and common product, and is not the focus of this device, so it is directly selected here without further explanation. The thermal insulation material layer can improve the thermal insulation effect, and the sound insulation material layer can improve the sound insulation effect. To improve the sound insulation performance of the wall panel, a clamping plate is fixedly connected to the side wall of the decorative panel. Trapezoidal grooves are provided on the side walls of both the outer and inner metal panels. The clamping plate corresponds to and engages with the trapezoidal grooves. Decorative panels are provided on the side walls of both the outer and inner metal panels to cover them, thereby improving the aesthetic appearance of the wall panel. During installation, the clamping plate is aligned with the trapezoidal groove and inserted into it to complete the installation.

[0006] Preferably, the sidewall of the thermal insulation material layer has a first through-hole, and the sidewall of the sound insulation material layer has a second through-hole. The first and second through-holes correspond to each other and have the same diameter. The transverse connector is a hollow metal tube, and its outer diameter matches the diameters of the first and second through-holes. When assembling the outer metal plate, inner metal plate, and intermediate functional layer, the thermal insulation material layer and sound insulation material layer are first bonded and fixed together, with the first and second through-holes corresponding. Then, the bonded and fixed thermal insulation material layer and sound insulation material layer are aligned with the outer metal plate, with the transverse connector passing through the first and second through-holes. Finally, the inner metal plate is assembled... The plate corresponds to the intermediate functional layer, and the tube end of the transverse connector extends to the large opening of the stepped groove. Then, the threaded cap corresponds to the transverse connector. By turning the threaded cap with the protruding handle, the threaded cap engages with the external thread to limit and fix the transverse connector. This allows the outer metal plate, inner metal plate, and intermediate functional layer to be assembled and fixed. It is important to note that when installing the threaded cap, it must be fully screwed into the large opening of the stepped groove so that the end face of the threaded cap is flush with the side wall of the inner metal plate to avoid affecting the installation of the subsequent decorative panels. The transverse connector is a hollow metal tube to reduce weight and allow for the installation of pipelines. The transverse connector improves the stability of the device.

[0007] Preferably, the thickness of the threaded cap is the same as the depth of the large groove of the stepped groove. The end face of the threaded cap is provided with a notch, and a protruding handle is fixedly connected to the inner wall of the notch. The end face of the protruding handle is flush with the end face of the threaded cap to avoid the protruding handle affecting the installation of the decorative panel. A first vertical plate is embedded and fixedly connected to one side of the outer metal plate and the inner metal plate. A slot is provided on the side wall of the first vertical plate. A second vertical plate is embedded and fixedly connected to the other side of the outer metal plate and the inner metal plate. A protruding plate is fixedly connected to the side wall of the second vertical plate. The slot and the protruding plate correspond to and cooperate with each other. After the assembly of the outer metal plate, the inner metal plate, the intermediate functional layer and the decorative panel are completed, when multiple of this device need to be spliced, multiple wall panels are placed side by side, and the protruding plates on two adjacent wall panels are inserted into the slots to complete the splicing of multiple wall panels.

[0009] 1. This utility model improves the thermal insulation and sound insulation performance of the wall panel by setting an intermediate functional layer. The outer metal plate, inner metal plate and intermediate functional layer can be disassembled and assembled. After long-term use, the intermediate functional layer can be disassembled to replace the thermal insulation material layer and the sound insulation material layer, so as to avoid the thermal insulation material layer and the sound insulation material layer aging and affecting the performance after long-term use.

[0010] 2. This utility model is easy to assemble and does not require welding. The horizontal connecting parts can improve the compressive strength. The horizontal connecting parts are hollow metal tubes, which can reduce the weight and allow pipelines to be run through them without the need to chisel pipeline grooves. Furthermore, the cooperation between the protruding plate and the slot facilitates the splicing of multiple wall panels. Attached Figure Description
