Description

Technical Field

[0001] This utility model relates to a combined thermal insulation rock wool board. Background Technology

[0002] Common materials used for the surface layer of sandwich panels include plywood, fiberboard, plastic sheets, and thin metal sheets. Core materials include balsa wood, rubber, cellulose acetate, plastics, resin-impregnated paper or fabric, and metal honeycomb structures. Rock wool is also a common core material.

[0003] Existing thermal insulation rock wool boards still have the following problems in practical use: the splicing structure of existing thermal insulation rock wool boards is complex to manufacture, costly, and time-consuming, which affects production efficiency and costs. Therefore, it is necessary to design corresponding technical solutions to solve the above problems. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a combined thermal insulation rock wool board to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a combined thermal insulation rock wool board, comprising two metal panels and a core board disposed between the two metal panels. The two metal panels are respectively fixedly connected to the core board, and the core board is made of rock wool. The feature is that each of the metal panels has vertically bent edges at both ends. One of the two vertically bent edges is connected to an outward protrusion, and the other vertically bent edge is connected to an inward concave portion. The outward protrusions of the two metal panels approach each other to form a splicing strip, and the inward concave portions of the two metal panels approach each other to form a splicing slot. The splicing strip is used to engage with the splicing slot.

[0006] Preferably, the outer wall of the vertically bent edge is provided with a filling groove.

[0007] Preferably, the metal panel is fixedly connected to the core board via an adhesive layer.

[0008] Preferably, the adhesive layer is an epoxy resin adhesive.

[0009] Preferably, the metal panel is an aluminum alloy plate or a stainless steel plate.

[0010] The combined thermal insulation rock wool board provided by this utility model has at least the following advantages compared with the prior art:

[0011] This invention features vertically bent edges at both ends of a metal panel. One of the bent edges is connected to an outward protrusion, and the other is connected to an inward concave portion. The outward protrusions of the two metal panels form a splicing strip, and the inward concave portions form a splicing slot. Two insulating rock wool boards can be spliced ​​together by interlocking the splicing strip and the splicing slot. The splicing operation is simple and convenient. Furthermore, the vertical bent edges, outward protrusions, and inward concave portions can all be formed by bending processes, making manufacturing simple and convenient, improving production efficiency, and reducing processing costs.

[0012] This invention provides a filling groove on the outer wall of the vertically bent edge. After two thermal insulation rock wool boards are spliced ​​together, sealant can be injected into the joint between the two boards. The sealant fills the filling groove and, after curing, it can tighten the two thermal insulation rock wool boards, making them more firmly connected together. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] The specific technical solution of this utility model is as follows:

[0018] In one specific embodiment, such as Figure 1 and Figure 2As shown, this utility model provides a combined thermal insulation rock wool board, including two metal panels 1 and a core board 2 disposed between the two metal panels 1. The two metal panels 1 are fixedly connected to the core board 2, and the core board 2 is made of rock wool. Each metal panel 1 has a vertical bending edge 11 at both ends. One of the two vertical bending edges 11 is connected to an outward protrusion 12, and the other vertical bending edge 11 is connected to an inward concave portion 13. The outward protrusions 12 of the two metal panels 1 approach each other to form a splicing insert 14, and the inward concave portions 13 of the two metal panels 1 approach each other to form a splicing slot 15. The splicing insert 14 is used to engage with the splicing slot 15.

[0019] The above solution involves setting vertical bending edges 11 at both ends of the metal panel 1, with one bending edge 11 connected to an outward protrusion 12 and the other bending edge 11 connected to an inward concave portion 13. When the two metal panels 1 are connected to the core board 2, the outward protrusions 12 of the two metal panels 1 will come together to form a splicing strip 14, and the inward concave portions 13 of the two metal panels 1 will come together to form a splicing slot 15. Therefore, the splicing combination of two thermal insulation rock wool boards can be achieved through the insertion and cooperation of the splicing strip 14 and the splicing slot 15, making the splicing operation simple and convenient. Furthermore, the vertical bending edges 11, the outward protrusions 12, and the inward concave portions 13 can all be formed by bending processes, making manufacturing simple and convenient, improving manufacturing efficiency, and reducing processing costs, making it suitable for widespread application.

[0020] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the outer wall of the vertical bending edge 11 is provided with a glue filling groove 16.

[0021] The above solution is adopted: by setting a filling groove 16 on the outer wall of the vertical bending edge 11, after the two thermal insulation rock wool boards are spliced, sealant 5 can be injected into the splice seam 4 of the two thermal insulation rock wool boards. The sealant 5 can fill the filling groove. After the sealant 5 is cured, it can tighten the two thermal insulation rock wool boards, so that the two thermal insulation rock wool boards are more firmly connected together.

[0022] In another specific embodiment, such as Figure 1 As shown, the metal panel 1 is fixedly connected to the core board 2 through the adhesive layer 3.

[0023] The above solution is adopted to fix the metal panel 1 to the core board 2 by adhesive bonding.

[0024] In another specific embodiment, the adhesive layer 3 is an epoxy resin adhesive.

[0025] In another specific embodiment, the metal panel 1 is an aluminum alloy plate or a stainless steel plate.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
