[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please refer to the following: Figures 1 to 5 The present invention provides a structurally stable external wall insulation board. The structurally stable external wall insulation board includes an insulation layer 1, a fireproof layer 2, positioning strips 3, and a supporting mesh 4. The length direction of the insulation layer 1 is defined as the first direction; the fireproof layer 2 is disposed on both sides of the insulation layer 1 along its thickness direction, and a guide rib 11 protrudes from one side of the insulation layer 1 along the first direction, while a guide groove is recessed on the other side; the positioning strip 3 is installed inside the guide groove along its length direction, and a positioning groove is recessed on the positioning strip 3; positioning ribs for sliding into the positioning groove protrude from the side of the guide rib 11; the supporting mesh 4 is entirely located inside the insulation layer 1, and is located on the side of the insulation layer 1.

[0027] The structurally stable external wall insulation board provided in this embodiment, compared with the prior art, features an insulation layer 1 with a fireproof layer 2 fixedly connected to both sides. Guide ribs 11 and guide grooves are respectively provided on both sides along the length of the insulation layer 1, enabling the positioning of two adjacent insulation boards during assembly. In this application, a positioning strip 3 is provided inside the guide groove. The positioning strip 3 has a stable structure and a positioning groove with an opening facing the same direction as the guide groove. On the other side of the fireproof layer 2, a positioning rib protrudes from the side of the guide rib 11 for sliding into the positioning groove. Furthermore, a support mesh 4 is installed inside the insulation layer 1 to enhance the side strength of the insulation layer 1. This application utilizes the support mesh 4 to enhance the overall strength of the insulation layer 1, and the stable positioning strip 3 ensures the stability of the relative position of the positioning groove on the insulation board, thereby guaranteeing the accuracy of the splicing positioning and the stability of the connection between the two insulation boards during splicing.

[0028] Specifically, in this embodiment, when two adjacent insulation boards are spliced ​​together, the guide protrusion on one insulation board slides into the guide groove on the other insulation board, and the fireproof layer 2 on the two adjacent insulation boards abuts against each other.

[0029] Preferably, in this embodiment, the spacing between the two sides of the guide rib 11 along the thickness direction of the insulation layer 1 gradually decreases in the direction away from the insulation layer 1. The width of the guide groove gradually increases in the direction away from the insulation layer 1.

[0030] In some embodiments, the aforementioned support mesh 4 can be adopted as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 The structure shown. See also Figure 2 The supporting mesh 4 includes a first mesh 41 and a second mesh 42 arranged adjacent to each other along a first direction. The first mesh 41 has a tail-end support piece 411 adapted to the shape of the inner wall of the guide groove, and the second mesh 42 has a head-end support piece 421 adapted to the shape of the guide rib 11. Both the tail-end support piece 411 and the head-end support piece 421 include multiple mesh pieces that are bent and connected to each other. The multiple mesh pieces on the tail-end support piece 411 are arranged parallel to each other at intervals along the inner wall of the guide groove. The multiple mesh pieces on the head-end support piece 421 are arranged parallel to each other at intervals along the outer wall of the guide rib. This provides support for the guide ribs 11 and the guide groove on both sides of the insulation layer 1 along the first direction, ensuring the strength of the guide ribs 11 and the guide groove, and preventing breakage of the guide ribs 11 or the guide groove, which would affect the normal use of the insulation layer 1.

[0031] Preferably, in this embodiment, the supporting mesh 4 adopts a split structure of the first mesh 41 and the second mesh 42, which makes it convenient to place the first mesh 41 and the second mesh 42 when processing the wall panel, and at the same time reduces the deformation of the supporting mesh 4 itself.

[0032] In some embodiments, the first mesh 41 and the second mesh 42 described above can be adopted as follows: Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4 The first mesh panel 41 is further provided with two first side support pieces 412 arranged parallel to the side of the insulation layer 1 at intervals. The second mesh panel 42 is further provided with two second side support pieces 422 arranged parallel to the side of the insulation layer 1 at intervals. The first side support pieces 412 and the second side support pieces 422 are stacked on top of each other at the connection points. The first side support pieces 412 and the second side support pieces 422 can be connected together by welding or binding. At the same time, it can ensure that the perimeter of the insulation layer 1 can be supported by the mesh panels, effectively improving the support strength of the insulation layer 1.

[0033] Specifically, in this embodiment, the first side support piece 412 and the second side support piece 422 are stacked on top of each other, which can enhance the strength of the insulation layer 1 at the connection between the first side support piece 412 and the second side support piece 422.

[0034] In some embodiments, the second side support piece 422 described above can be adopted as follows: Figure 4 The structure shown. See also Figure 4 The end of the second side support piece 422 is bent inward into the insulation layer 1 and has an overlap portion 423. The overlap portion 423 is superimposed on the first side support piece 412 on the first mesh piece 41. The overlap portion 423 is bent at one side of the second side support piece 422 near the first side support piece 412. When the first side support piece 412 and the second side support piece 422 are connected together, the overlap portion 423 is parallel to the first side support piece 412. Furthermore, the side of the first side support piece 412 can abut against the bend of the first side support piece 412 and the overlap portion 423, which serves to position the first mesh piece 41 and the second mesh piece 42 relative to each other.

[0035] In some embodiments, the second side support piece 422 and the first end support piece 421 described above can be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The second side support plate 422 and the first end support plate 421 are separate structures connected together. The second support plate and the first end support plate 421 can be made of mesh of different specifications. The support strength of the first end support plate 421 is greater than that of the second side support plate 422. When processing the insulation board, the first end support plate 421 can be fixed first, and then the second side support plate 422 can be connected to it. This facilitates the stability of the positions of the second side support plate 422 and the first end support plate 421 during the production and processing of the insulation board. The first end support plate 421 is formed by bending and is made of high-strength mesh, which effectively strengthens the guide rib 11 and prevents deformation or breakage of the guide rib 11.

[0036] In some embodiments, the second side support piece 422 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The second side support piece 422 has a first connecting portion 424 bent along its side, and the first end support piece 421 has a second connecting portion 425 bent along its side, connecting to the first connecting portion 424. The first connecting portion 424 is perpendicular to the second side support piece 422 and is bent inwards towards the insulation layer 1. The second connecting portion 425 is bent along two sides of the first end support piece 421 along the thickness direction of the insulation layer 1. The first connecting portion 424 and the second connecting portion 425 can be connected by binding or welding. Through the connection between the first connecting portion 424 and the second connecting portion 425, the first end support piece 421 can be connected to the two second side support pieces 422 together. At the same time, the first connecting portion 424 and the second connecting portion 425 are bent onto the second side support piece 422 and the first end support piece 421 respectively, which can enhance the strength of the second side support piece 422 and the first end support piece 421.

[0037] In some embodiments, the aforementioned head support piece 421 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The first end support plate 421 has a bent reinforcing part 426 for strengthening the positioning rib. The reinforcing part 426 is located inside the positioning rib and is adapted to the shape of the positioning rib. The reinforcing part 426 is bent in the middle of the first end support plate 421 and protrudes outward from the first end support plate 421 to support the positioning rib on the insulation layer 1, thereby strengthening the positioning rib and ensuring its stability.

[0038] In some embodiments, the positioning bar 3 may be adopted as follows: Figure 2 , Figure 5 The structure shown. See also... Figure 2 , Figure 5The positioning strip 3 is fixedly installed on the end face of the support mesh 4. The side of the positioning strip 3 is provided with a slot for engaging the reinforcing bars on the support mesh 4. The positioning strip 3 is fixedly installed on the support mesh 4. Multiple slots are recessed on the side of the positioning strip 3 away from the positioning groove. The cross-section of the slot is an arc-shaped structure, and the opening width on one side of the slot is smaller than the inner diameter of the slot. This allows the steel wires on the support mesh 4 to be engaged into the slots, thus fixing the positioning strip 3 to the support mesh 4.

[0039] Preferably, in this embodiment, multiple slot groups are provided on the positioning strip 3. The multiple slot groups are arranged sequentially at intervals along the length direction of the positioning strip 3, and each slot group contains multiple slots. The appropriate slots can be selected for connection according to the spacing of the steel wires on the support mesh 4.

[0040] In some embodiments, the positioning bar 3 may be adopted as follows: Figure 2 , Figure 5 The structure shown. See also... Figure 2 , Figure 5 The positioning strip 3 has multiple protruding teeth 31 on both sides along the thickness direction of the insulation layer 1 to prevent it from detaching from the insulation layer 1. Multiple teeth 31 extend outward from both sides of the positioning strip 3 along the thickness direction of the insulation layer 1, and are arranged at intervals along the thickness direction of the positioning strip 3. This ensures that after the insulation board is manufactured, the teeth 31 are located inside the insulation layer 1, thereby improving the connection strength between the positioning strip 3 and the insulation layer 1 and preventing the positioning strip 3 from detaching from the insulation layer 1.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
