Description

Technical Field

[0001] This utility model relates to the field of color steel composite panel technology, and in particular to a self-cleaning color steel composite panel. Background Technology

[0002] Color-coated steel composite panels are building maintenance panels made of color-coated steel sheets or other metal sheets as the surface layer and thermal insulation core material as the sandwich layer, and are bonded together by adhesives or foaming processes. They are mainly used in industrial plants, cold storage, prefabricated houses and other scenarios. They have high strength and can be used as maintenance structures and load-bearing structures. Their performance optimization is of great significance to improving the overall quality of buildings and the user experience.

[0003] The existing technology has the following shortcomings: Because traditional color steel composite panels only have a surface layer on one side, and the surface layer is mostly a common coating, it does not have the ability to repel dirt and clean itself. As a result, it is easy to attract dust, rainwater residue, and industrial oil stains during long-term use. This not only affects the cleanliness of the appearance, but also reduces the durability of the panels due to the accumulation of dirt. At the same time, the existing equipment does not have a dedicated splicing and connection structure. Splicing often relies on simple bolt fixing, which is not only inefficient in installation, but also has poor sealing at the splice joints, making it easy for rainwater to seep in. In addition, there is no directional flow guidance structure, so natural rainwater cannot effectively wash away surface stains, requiring frequent manual cleaning, increasing maintenance costs and safety hazards. Utility Model Content

[0004] This utility model proposes a self-cleaning color steel composite panel, which has the beneficial effects of double-sided self-cleaning and anti-fouling, convenient splicing and reliable sealing, and no need for frequent manual cleaning, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-cleaning color steel composite panel, comprising two square metal edging frames, wherein the color steel composite panel body is fixedly connected to the inner side of the square metal edging frames, and a connecting component is provided on the opposite sides of the two square metal edging frames.

[0006] The color steel composite panel body includes a bottom substrate, which is fixedly connected to the inner center of a square metal edging frame. Insulation core layers are fixedly connected to both the upper and lower sides of the bottom substrate. An outer color steel surface layer is fixedly connected to the side of the insulation core layer away from the bottom substrate. Several arc-shaped flow-guiding protrusions are provided on the side of the outer color steel surface layer away from the insulation core layer. A bottom adhesion coating is provided on the side of the outer color steel surface layer away from the insulation core layer. A superhydrophobic self-cleaning surface coating is provided on the side of the bottom adhesion coating away from the outer color steel surface layer. The bottom adhesion coating uses an epoxy zinc-rich primer, and the superhydrophobic self-cleaning surface coating uses a modified polytetrafluoroethylene and silica composite coating.

[0007] Preferably, the bottom substrate is made of galvanized steel sheet, and the insulation core layer is made of high-density rock wool core material.

[0008] Preferably, waterproof sealing strips are fixedly connected to both the upper and lower sides of the inner surface of the square metal edging frame, and connecting grooves are provided on both the left and right sides of the outer surface of the square metal edging frame. Three positioning holes are provided on both the upper and lower sides of the inner wall of the connecting groove.

[0009] Preferably, the connecting assembly includes a connecting post, the outer surface of which is slidably engaged with the inner surface of the connecting groove, and three connecting grooves are provided in the middle of the connecting post.

[0010] Preferably, a bidirectional screw is rotatably connected to the middle of the connecting groove, and the upper and lower ends of the bidirectional screw pass through the upper and lower sides of the connecting column respectively and are fixedly connected to knobs.

[0011] Preferably, the outer surface of the bidirectional screw is threaded with threaded sliding plates on both the upper and lower sides. The outer surface of the threaded sliding plates is slidably connected to the inner surface of the connecting groove. The left and right ends of the threaded sliding plates are fixedly connected with positioning pins. The end of the positioning pin away from the threaded sliding plate extends through to the inner surface of the positioning hole.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, through the cooperation between the outer color steel surface layer, the arc-shaped guide ridge, the bottom adhesion coating and the surface superhydrophobic self-cleaning coating, the bottom adhesion coating enhances the bonding stability between the outer color steel surface layer and the surface superhydrophobic self-cleaning coating, preventing the coating from peeling off. The surface superhydrophobic self-cleaning coating uses its superhydrophobicity to make it difficult for rainwater and oil stains to adhere. The arc-shaped guide ridge guides rainwater to flow along a fixed path, forming a directional scouring force. On the one hand, the superhydrophobic coating can reduce the adhesion of dust and stains, and on the other hand, the arc-shaped guide ridge enhances the scouring effect of rainwater, achieving double-sided self-cleaning. Frequent manual cleaning is not required, which reduces maintenance costs and avoids the safety hazards of high-altitude cleaning. At the same time, the bottom adhesion coating improves the durability of the coating and extends the overall service life of the board.

[0013] 2. In this utility model, through the cooperation between the square metal edging frame, the connecting components, and the waterproof sealing strip, the connecting post is inserted into the connecting groove of the two square metal edging frames during splicing. Turning the knob drives the bidirectional screw to rotate, and the bidirectional screw drives the upper and lower threaded slide plates to slide in opposite directions, so that the positioning pin is inserted into the positioning hole for fixation. At the same time, the waterproof sealing strip in the square metal edging frame seals the gap between the frame and the color steel composite panel body. On the one hand, through the combination structure of the connecting post, the bidirectional screw, and the positioning pin, the adjacent panels can be spliced ​​quickly and accurately without the need for additional connecting parts, thus improving installation efficiency. On the other hand, the waterproof sealing strip, in conjunction with the splicing structure, effectively prevents rainwater from seeping in from the gaps in the frame and the splicing points, avoiding the insulation core layer from getting damp and moldy, and ensuring the insulation performance and structural stability of the panel.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order 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 present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: it includes two square metal edging frames 1, with a color steel composite panel body 2 fixedly connected to the inner side of the square metal edging frames 1. A connecting component 3 is provided on the opposite sides of the two square metal edging frames 1. The color steel composite panel body 2 includes a bottom substrate 21, which is fixedly connected to the inner center of the square metal edging frames 1. Insulation core layers 22 are fixedly connected to both the upper and lower sides of the bottom substrate 21. An outer color steel surface layer 23 is fixedly connected to the side of the insulation core layer 22 away from the bottom substrate 21. The outer side of the color steel surface layer 23 away from the insulation core layer 22 is provided with several arc-shaped flow guiding ridges 231. The outer side of the color steel surface layer 23 away from the insulation core layer 22 is provided with a bottom adhesion coating 232. The outer side of the bottom adhesion coating 232 away from the outer side of the color steel surface layer 23 is provided with a surface superhydrophobic self-cleaning coating 233. The bottom adhesion coating 232 is made of epoxy zinc-rich primer, and the surface superhydrophobic self-cleaning coating 233 is made of modified polytetrafluoroethylene and silicon dioxide composite coating. The bottom substrate 21 is made of galvanized steel plate, and the insulation core layer 22 is made of high-density rock wool core material. The overall effect achieved by Embodiment 1 is as follows: the bottom substrate 21 is made of galvanized steel plate, which can significantly improve the overall structural strength and corrosion resistance of the color steel composite panel body 2, and avoid damage to the substrate caused by moisture erosion inside the building; the insulation core layer 22 is made of high-density rock wool core material, which can not only ensure excellent thermal insulation performance and reduce heat exchange between the inside and outside of the building, but also has good fire resistance, which can meet the use needs of industrial plants and other scenarios with high fire protection requirements; the bottom adhesion coating 232 on the surface of the outer color steel surface layer 23 can tightly bond the outer color steel. The surface layer 23 and the superhydrophobic self-cleaning coating 233 effectively prevent coating peeling during long-term use and ensure stable self-cleaning function. The superhydrophobic self-cleaning coating 233, with its own superhydrophobicity, makes it difficult for rainwater and industrial oil to adhere to the surface of the outer color steel surface layer 23. Combined with the arc-shaped guide ridge 231, it guides rainwater to flow along a fixed path, forming a directional scouring force that can quickly remove surface dust and light stains, achieving a double-sided self-cleaning effect for the color steel composite panel body 2. This significantly reduces the frequency of manual cleaning, lowers maintenance costs, and reduces safety hazards associated with high-altitude operations.

[0019] Example 2: Figure 2 and Figure 4As shown, this utility model provides a technical solution: waterproof sealing strips 11 are fixedly connected to the upper and lower sides of the inner surface of the square metal edging frame 1, and connecting grooves 12 are opened on the left and right sides of the outer surface of the square metal edging frame 1. Three positioning holes 13 are opened on the upper and lower sides of the inner wall of the connecting groove 12. The connecting component 3 includes a connecting post 31. The outer surface of the connecting post 31 is slidably engaged with the inner surface of the connecting groove 12. Three connecting grooves 32 are opened in the middle of the connecting post 31. A bidirectional screw 33 is rotatably connected to the middle of the connecting groove 32. The upper and lower ends of the bidirectional screw 33 pass through to the upper and lower sides of the connecting post 31 respectively and are fixedly connected to knobs 34. Threaded sliding plates 35 are threadedly connected to the upper and lower sides of the outer surface of the bidirectional screw 33. The outer surface of the threaded sliding plate 35 is slidably connected to the inner surface of the connecting groove 32. Positioning pins 36 are fixedly connected to the left and right ends of the threaded sliding plate 35. The end of the positioning pin 36 away from the threaded sliding plate 35 passes through to the inner surface of the positioning hole 13. The overall effect achieved by Embodiment 2 is as follows: the waterproof sealing strip 11 on the inner surface of the square metal edging frame 1 can tightly adhere to the outer color steel surface layer 23, effectively sealing the gap between the square metal edging frame 1 and the color steel composite panel body 2, preventing rainwater and moisture from seeping into the insulation core layer 22 from the edge, avoiding the insulation core layer 22 from getting damp and moldy, and ensuring its long-term stable insulation performance; during splicing, the connecting post 31 of the connecting component 3 is inserted into the connecting groove 12 of two adjacent square metal edging frames 1, and the knob 34 is turned to drive the bidirectional screw 33 to rotate. 3. The upper and lower threads rotate in opposite directions, which can drive the upper and lower threaded slide plates 35 to slide in opposite directions along the connecting slide groove 32, thereby driving the positioning pins 36 at both ends of the threaded slide plates 35 to insert into the positioning holes 13 on the inner wall of the connecting groove 12, realizing the rapid fixing of adjacent color steel composite panels without the need for additional connectors, significantly improving installation efficiency; at the same time, the tight fit between the positioning pins 36 and the positioning holes 13 can ensure the structural stability after splicing, and avoid loosening due to vibration and other factors during long-term use. Combined with the waterproof sealing strip 11, it further improves the sealing performance of the splice.

[0020] The working principle of the entire device is as follows: During daily use, the outer color steel surface layer 23 on both sides of the color steel composite panel body 2 prevents rainwater and oil stains from adhering to its surface through the superhydrophobic self-cleaning coating 233. Rainwater falling on the outer color steel surface layer 23 will flow along a fixed path under the guidance of the arc-shaped guide ridge 231, forming a directional scouring force to wash away surface dust and minor stains, thus achieving a self-cleaning function. The bottom adhesion coating 232 ensures the connection stability between the superhydrophobic self-cleaning coating 233 and the outer color steel surface layer 23, preventing the coating from falling off and affecting the self-cleaning effect. The bottom substrate 21 provides structural support for the entire color steel composite panel body 2, and the thermal insulation core layer 22 achieves thermal insulation inside and outside the building, reducing energy loss. When multiple color steel composite panels need to be spliced, first align the square metal edging frames 1 of the panels to be spliced, insert the connecting post 31 of the connecting component 3 into the connecting groove 12 of the two square metal edging frames 1, turn the knob 34 to rotate the bidirectional screw 33, the bidirectional screw 33 drives the threaded slide plate 35 to slide along the connecting slide groove 32, causing the positioning pin 36 to be inserted into the positioning hole 13, thus completing the fixation of the two panels; during this process, the waterproof sealing strip 11 inside the square metal edging frame 1 seals the gap between the frame and the color steel composite panel body 2, and the connecting post 31 at the splicing point cooperates with the connecting groove 12 to form a double sealing structure, effectively preventing rainwater from seeping in from the gap, ensuring the sealing and stability of the entire composite panel structure, and meeting the needs of long-term use.
