[0036] In order to more clearly explain the overall concept of the present invention, the following will be further described in detail by way of examples in combination with the drawings of the specification.

[0037] It should be noted that many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0038] Such asFigures 1-4 As shown in the figure, the present application discloses a novel assembled thermal insulation board joint water-stop structure, which mainly includes a board edge connection structure, a board edge strengthening structure, and a strengthening connecting piece. Among them, the board edge connection structure includes a groove 11 penetrating through the side of the thermal insulation board 1 along the length direction of the thermal insulation board 1, a casting groove 2 formed by corresponding grooves 11 of two adjacent thermal insulation boards 1, and a strengthening connection part 13 arranged outside the side wall 12 of the groove 11; the strengthening connecting piece includes a welding part 7 arranged on the side wall 12 of the groove 11, and a plurality of welding parts 7 are arranged along the extending direction of the groove 11, and the welding parts 7 of two adjacent thermal insulation boards 1 correspond to each other one by one; the board edge strengthening structure includes a first filling layer 21 arranged inside the casting groove 2, a second filling layer 31 arranged between two adjacent grooves 11, a mesh cloth 4 layer, a strengthening layer 5 arranged on the strengthening connection part 13, and a finishing layer 6 arranged outside the board surface of the thermal insulation board 1 and the mesh cloth 4 layer and the strengthening layer 5.

[0039] By adopting the above structure, the stability of the connection structure between the assembled thermal insulation boards 1 can be effectively improved, thereby avoiding the problem of water leakage caused by joint cracking and failure of the joint water-stop structure, ensuring the construction quality, and the above-mentioned board edge connection structure, board edge strengthening structure, and strengthening connecting piece have a simple structure and are convenient to use in combination, which is beneficial to improving the construction efficiency while ensuring the construction quality.

[0040] As a preferred embodiment of the present application, the width of the groove 11 in the direction perpendicular to the board surface of the thermal insulation board 1 does not exceed one-third of the thickness of the thermal insulation board 1; the width of the strengthening connection part 13 in the width direction of the board surface of the thermal insulation board 1 is not less than the depth of the groove 11. Preferably, the width range of the strengthening connection part 13 is set to 50-100 mm. Adopting this setting method can facilitate the setting of the strengthening connection part 13 and avoid the adverse impact of the too large sizes of the strengthening connection part 13 and the groove 11 on the structural strength of the thermal insulation board 1 body.

[0041] Furthermore, referring to Figure 1 As shown in the figure, the thermal insulation board 1 includes a metal support part 14 and a casting layer coated outside the metal support part 14, and the welding part 7 is integrally formed with the metal support part 14 or the welding part 7 is welded and fixed to the metal support part 14. As a preferred embodiment of the present application, when the board width is less than 1.2 meters or the board height is less than 3 meters, the metal support part 14 is a wire mesh, and when the board width is more than 1.2 meters or the board height is more than 3 meters, the metal support part 14 is a wire mesh and a steel skeleton. Preferably, the steel skeleton is made by processing C-shaped steel. At the same time, the welding part 7 is preferably made of angle steel. Angle steel, as a common material, has the advantages of wide source, low cost, convenient processing and use, etc., and the shape of the angle steel can also directly adapt to the board edge structure of the thermal insulation board 1, which is convenient for the processing and forming of the thermal insulation board 1.

[0042] In the above solution, the setting of the metal support part 14 can effectively improve the structural strength of the insulation board 1, and the setting of the metal support part 14 makes it more convenient to set the welding parts, so that the insulation board 1 in the present application can improve the stability of the inter-board connection structure while effectively exerting the heat preservation effect, which is conducive to avoiding the failure of the water stop structure caused by the cracking of the inter-board seam. At the same time, it can also improve the seismic resistance of the external wall insulation layer structure and reduce the safety risk caused by the rupture and shedding of the external wall insulation layer structure.

[0043] Further, referring to Figure 4 As shown, there is a joint gap surrounded by the side wall 12 of the groove 11 of two adjacent insulation boards 1 and the welding part 7, and the second filling layer 31 is arranged in the joint gap. Preferably, the second filling layer 31 is a waterproof grease layer. Due to the setting of the welding part 7, there must be a joint gap at the joint between the two insulation boards 1. The setting of the first filling layer 21 and the second filling layer 31 (especially the second filling layer 31) can effectively block the joint gap, thereby improving the stability of the inter-board joint structure. At the same time, using waterproof grease as the material of the second filling layer 31 can also improve the waterproof ability at the joint gap and avoid the corrosion of the welding part 7, the first filling layer 21, etc. caused by water seepage at the joint gap during long-term use, resulting in the failure of the inter-board connection structure.

[0044] In the above solution, the welding connection between the boards is realized by setting the welding part 7, so as to ensure the stability of the inter-board connection structure of the assembled insulation board 1 and avoid the failure of the joint water stop structure caused by joint cracking.

[0045] Further, referring to Figure 3 As shown, along the direction perpendicular to the board surface of the insulation board 1, the new assembled insulation board joint water stop structure in the present application is, from inside to outside, the first filling layer 21, the side wall 12 of the groove 11 and the second filling layer 31, the strengthening connecting piece, the mesh cloth 4, the strengthening layer 5 and the decorative layer 6. During the actual construction process, first, the grooves 11 of the two insulation boards 1 are aligned and spliced to form a casting groove 2, then the corresponding welding parts 7 of the two insulation boards 1 are welded to achieve stable connection between the adjacent two insulation boards 1. After welding, the casting groove 2 is cast to form the first filling layer 21, then the waterproof grease is applied to the aforementioned joint gap between the two insulation boards 1 to form the second filling layer 31, and then the mesh cloth 4 is laid on the strengthening connecting part 13 and the strengthening layer 5 and the decorative layer 6 are applied in sequence. Preferably, the first filling layer 21 is a slightly expanded waterproof mortar layer, and cellulose is added to improve its crack resistance and further improve its waterproof and water stop performance. Further, referring to Figure 3 As shown, the strengthening layer 5 includes a crack-resistant mortar layer 51 and a waterproof layer 52 arranged between the crack-resistant mortar layer 51 and the decorative layer 6.

It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art.
