[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] See Figure 1-5As shown, a high-strength sandwich color steel plate includes a lower plate 1, an upper plate 2, and a core plate 3 disposed between the lower plate 1 and the upper plate 2. The core plate 3 is made of rock wool, and the core plate 3 is glued to the lower plate 1 and the upper plate 2 respectively. A side plate 4 is disposed on a pair of long sides of the core plate 3 located between the lower plate 1 and the upper plate 2, and a sealing plate 5 is disposed on a pair of short sides of the core plate 3 respectively. The side plates 4 and the sealing plates 5 are glued to the core plate 3 around its perimeter, and the side plates 4 and the sealing plates 5 are fixedly connected to the lower plate 1 and the upper plate 2 respectively, thereby forming an integral structure and improving the strength of the sandwich color steel plate.

[0033] The materials of the lower plate 1, the upper plate 2, the side plate 4, and the sealing plate 5 are preferably galvanized steel plates or stainless steel plates. In this embodiment, the lower plate 1, the side plate 4, and the sealing plate 5 are made of stainless steel plates, while the upper plate 2 is made of galvanized steel plates. Furthermore, it should be noted that the connection between the side plate 4 and the sealing plate 5 and the lower plate 1 and the upper plate 2 can be achieved by screws or by welding or other methods. In this embodiment, the side plate 4 and the sealing plate 5 are connected to the lower plate 1 by screws, and the side plate 4 and the sealing plate 5 are connected to the upper plate 2 by welding.

[0034] See Figure 1-4 As shown, in this embodiment, one set of the two sets of side plates 4 is provided with a mounting groove 41, while the other set of side plates 4 is provided with a mounting block 42. During assembly, refer to... Figure 6-9 As shown, the mounting groove 41 and the mounting block 42 cooperate to achieve quick docking of two adjacent sets of color steel plates of this application; wherein, in this embodiment, the mounting groove 41 is a conical groove, and the shape and size of the mounting block 42, as well as the fact that when the mounting block 42 is inserted into the mounting groove 41, the upper and lower side walls of the mounting block 42 should fit against the groove wall of the mounting groove 41, and the front end of the mounting block 42 should have a gap with the bottom of the mounting groove 41.

[0035] Further, see Figure 2-3 As shown, in this embodiment, two sets of positioning pins 6 are provided on the bottom surface of the mounting groove 41, and two sets of positioning holes 421 are provided on the mounting block 42; the two sets of positioning holes 421 are opposite to the two sets of positioning pins 6 one-to-one, that is, the axial center line of each set of positioning holes 421 coincides with the axial center line of its opposite positioning pin 6. During assembly, refer to... Figure 9 As shown, the cooperation between the positioning pin 6 and the positioning hole 421 can effectively prevent misalignment when two adjacent sets of color steel plates of this application are joined, thus affecting subsequent assembly and aesthetics.

[0036] Further, see Figure 9 As shown, in this embodiment, a limiting groove 61 is formed around the outer surface of the positioning pin 6 along the circumferential direction; see also Figure 1-5 and Figure 9 As shown, the mounting block 42 has threaded holes 422 that correspond one-to-one with the positioning holes 421. The threaded holes 422 and their corresponding positioning holes 421 are perpendicular to each other and are connected. When two adjacent sets of color steel plates of this application are joined together, see [reference to previous section]. Figure 9 As shown, after the positioning pin 6 is inserted into the positioning hole 421, a headless screw is screwed into the threaded hole 422 and the front end of the headless screw is pushed into the limiting groove 61, thereby restricting the positioning pin 6 in the positioning hole 421, thus connecting the two sets of color steel plates of this application together and improving the connection strength.

[0037] Further, see Figure 1-2 and Figure 5 As shown, in this embodiment, two sets of resin openers / closers 7 are provided on the inner bottom surface of the mounting groove 41. Of course, the above is only one implementation method and is not intended to limit the scope of this application. In actual installation, other numbers of sets can be used, as long as there is at least one set. See also... Figure 1 , Figure 3 and Figure 5 As shown, the mounting block 42 has a number of mounting holes 423 equal to the number of resin openers / closers 7, i.e., two sets of mounting holes 423 are provided. The two sets of mounting holes 423 are also aligned one-to-one with the two sets of resin openers / closers 7, meaning that the axial center line of each set of mounting holes 423 coincides with the axial center line of the resin opener / closer 7 opposite to it. During assembly, refer to... Figure 10 As shown, the cooperation between the resin opener / closer 7 and the mounting hole 423 ensures the tightness of the connection when two adjacent sets of color steel plates are joined together. This improves the connection strength between the color steel plates and effectively prevents relative movement between adjacent sets of color steel plates during connection, which would affect subsequent connection operations. For example, it would affect the insertion of the headless screw into the limiting groove 61 as described above, thus affecting construction efficiency.

[0038] Further, see Figure 1-4 As shown, in this embodiment, a groove 424 is provided on the upper end surface of the mounting block 42. The main function of the groove 424 is, see... Figure 8 As shown, the sealing ring 8 is used for installation. By setting the sealing ring 8, it can effectively prevent rainwater and other water from seeping downward through the connection between the two sets of color steel plates after the two sets of adjacent color steel plates are connected through the mounting groove 41 and the mounting block 42, which would lead to water leakage and other problems.

[0039] Further, see Figure 3 and 5 As shown, in this embodiment, the core plate 3 located between the lower plate 1 and the upper plate 2 is provided with two sets of reinforcing plates 9, but it is not limited to two sets; other sets can also be provided, depending on actual needs. The two sets of reinforcing plates 9 are evenly distributed between the core plates 3. By providing the reinforcing plates 9, the load-bearing strength of the middle part of the color steel plate of this application is improved, thereby improving the overall load-bearing strength and meeting the requirements of bearing a large weight.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
