Description

Technical Field

[0001] This utility model relates to the field of lightweight building wall materials, and in particular to a sandwich color steel wall panel structure with integrated cable routing function. Background Technology

[0002] Traditional sandwich panel wall systems are widely used in lightweight buildings, prefabricated houses, and factory buildings, favored for their advantages such as lightweight yet high strength, convenient construction, and thermal insulation. However, in practical use, it is usually impossible to directly pre-install cables inside the wall. If wiring is required, additional grooves must be cut and exposed conduits laid after installation, leading to extended construction time, compromised wall sealing, and significant aesthetic impact. Furthermore, improper electrical wiring can easily cause safety hazards. Therefore, there is an urgent need for a sandwich panel structure that can integrate wiring functionality into the wall panel structure, enabling concealed cable routing, thereby improving construction efficiency and overall wall performance.

[0003] The purpose of this utility model is to provide a sandwich color steel wall panel structure with integrated cable routing function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A sandwich-type color steel wall panel structure with integrated cable routing function includes an outer color steel plate, an inner color steel plate, a sandwich filling layer, and a cable trough layer. The outer and inner color steel plates are arranged opposite each other and connected and fixed by a frame skeleton. The sandwich filling layer fills the space between the outer and inner color steel plates. The cable trough layer is embedded in the middle of the sandwich filling layer and is arranged along the length or width of the wall panel structure. One or more cable duct channels are formed inside the cable trough layer for the passage of cables.

[0006] Preferably, the cable tray layer is made of polyethylene or flame-retardant plastic material and has pressure-resistant and moisture-proof functions.

[0007] Preferably, the diameter of the cable conduit channel is in the range of 20mm–50mm, and can be customized according to the predetermined cable harness specifications.

[0008] Preferably, the trough pipe layer and the sandwich filling layer are fixed by snap-fit ​​connection or adhesive bonding.

[0009] Preferably, the core filling layer is made of polyurethane foam, rock wool, or polystyrene foam.

[0012] Preferably, the cable tray layer has a reserved outlet along the length of the wall panel for connecting indoor sockets, switches or junction boxes.

[0013] Preferably, after the wall panels are installed, cables can be directly passed through the cable tray layer through multiple wall panels to achieve continuous wiring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This sandwich color steel wall panel structure with integrated cable routing function allows for cable pre-embedding during wall panel installation, significantly shortening the construction cycle, reducing subsequent grooving and repair procedures, and improving overall construction efficiency.

[0016] 2.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a sandwich color steel wall panel structure with integrated cable routing function, which includes an outer color steel plate (1), an inner color steel plate (2), a sandwich filling layer (3), a cable tray pipe layer (4) and a frame frame (5). The outer color steel plate (1) and the inner color steel plate (2) are arranged opposite to each other and are connected and supported by the frame frame (5) to form an overall frame closed wall panel unit.

[0025] The sandwich filling layer (3) is located between the outer color steel plate (1) and the inner color steel plate (2). It is made of high-density polyurethane foam, rock wool or polystyrene foam to provide good thermal insulation, sound insulation and flame retardant performance, while filling and supporting the overall structural strength of the wall panel.

[0026] The cable tray layer (4) is embedded inside the sandwich filling layer (3), preferably in the middle area near the inner color steel plate (2). The cable tray layer (4) is laid through the wall panel along its length, forming at least one cable duct channel (41) inside. The channel diameter ranges from 20mm to 50mm, and the specific size can be set according to the wiring requirements to accommodate different specifications of power lines, low-voltage lines, network cables, etc.

[0027] The cable duct channel (41) is made of flame-retardant polyethylene or flame-retardant modified PVC material, which has good pressure resistance, moisture resistance and flame retardant properties, ensuring the safety and reliability of the cable after laying.

[0028] In order to further improve the environmental durability of sandwich color steel wall panels, this utility model provides anti-corrosion coatings on the outer surfaces of both the outer color steel plate (1) and the inner color steel plate (2). The anti-corrosion coating adopts an epoxy zinc-rich primer + fluorocarbon topcoat composite system, and the total thickness of the coating is controlled between 80 and 120 micrometers. The coating method adopts a spraying process to ensure that the coating is uniform and firmly adhered, effectively resisting salt spray corrosion, acid and alkali erosion and outdoor ultraviolet aging, adapting to various complex climatic environments, and extending the service life of the wall.

[0029] The frame frame (5) is made of aluminum alloy profile or galvanized steel profile and is equipped with a reinforcing rib structure to improve the bending and impact resistance of the overall wall panel unit and facilitate on-site wall panel assembly and fixing.

[0030] The installation and usage steps are as follows:

[0031] First, during the factory production stage, the outer color steel plate (1), the sandwich filling layer (3), the inner color steel plate (2) and the trough pipe layer (4) are integrally formed, and the edge sealing is assembled through the frame skeleton (5) to form a prefabricated wall panel unit.

[0032] During on-site construction, each wall panel unit is positioned sequentially according to the architectural design drawings and connected and fixed to structural components such as keel and cross braces through the frame frame (5). The wall panels can be installed by bolt connection, self-tapping screw fixing or slot-type snap-fit ​​to ensure that the overall wall is continuous and firm.

[0033] After the wall panels are in place, cables are introduced into the conduit through the reserved outlet (42) of the cable tray layer (4). When introducing cables, construction workers can use a cable puller to smoothly pass power lines, lighting lines, low voltage network lines, etc. through the cable conduit channel (41), through multiple adjacent wall panel units, and finally connect to the indoor socket box, distribution box or network panel.

[0034] The wiring route is as follows: The cable first enters the cable tray layer (4) from the power supply point or distribution box through the reserved outlet (42), runs horizontally along the length of the wall panel, and is led out through the preset opening or connecting flexible tube at the location where it needs to be led out (such as switch, socket, low voltage port), and the end connection is completed. The cable is completely hidden inside the wall, without the need for additional grooves or exposed pipes, ensuring that the wall surface is continuous, intact and beautiful.

[0035] Once the wall is fully assembled, the overall wall surface is smooth and flat, with no visible traces of cable routing. Because all cables are enclosed inside the cable tray layer (4), external mechanical damage, moisture erosion, and rodent infestation are effectively prevented. At the same time, it facilitates later maintenance and expansion, greatly improving electrical safety and engineering durability.

[0036] Compared to the traditional method of grooving and laying pipes in the later stage of wall panel construction, the overall construction process can save at least 30% of the construction period, reduce labor and material costs by about 20%, and improve the overall finished product rate and appearance standardization of the project. It is suitable for large-scale application in various scenarios such as industrial plants, office buildings, temporary buildings, and light steel mobile houses.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
