[0038] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. The specific structure of the utility model is as follows Figure 1-Figure 5 as shown in .

[0040] The entire exterior wall insulation repair structure system uses metal-faced sandwich panels 4 as decorative surface layers and metal anchoring components as point-hanging supports. Without removing the original wall insulation layer 2, the metal anchoring components are used to achieve multi-point anchoring with the base wall 1 to form an insulation decorative exterior wall system.

[0041] In any of the above schemes, it is preferred that the anchor assembly 6 is a metal anchor assembly; the inner end of the metal anchor assembly is fixed to the base wall 1 by an expansion bolt 7, and the outer end of the metal anchor assembly is fixed to the metal surface sandwich panel 4 by a self-tapping screw 10.

[0042] In any of the above solutions, it is preferred that an open tongue-and-groove structure is provided at the longitudinal seams of the adjacent metal-faced sandwich panels 4 .

[0043] The open tongue-and-groove structure can achieve a self-sealing effect and effectively solve the impact of cold bridges.

[0044] The metal-faced sandwich panel 4 tongue and groove adopts an open structure and a metal-faced sandwich panel 4 opening edge finishing method, which effectively solves the edge pressure cold bridge problem and improves the overall thermal insulation performance of the exterior wall.

[0045] In any of the above schemes, it is preferred that each of the self-tapping screws 10 cooperates to seamlessly reinforce the corresponding wall insulation layer 2 and the finishing layer 3 against the base wall 1 and simultaneously forms a new insulation structure with the insulation layer in the corresponding metal-faced sandwich panel 4.

[0046] Under the installation pressure of each self-tapping screw 10, the insulation layer of the existing building is tightly fitted so that the entire system forms a cavity-free structural system; after installation, the original insulation system of the wall is protected and reinforced, and a new insulation layer structure is added at the same time.

[0047] The construction steps of removing the insulation layer and the finishing layer are saved. At the same time, the original insulation layer is sealed inside the metal-faced sandwich panel 4 under the action of the new insulation system, and the insulation effect can still be achieved. The installed system realizes the double-layer insulation effect, which increases the insulation effect compared with the original insulation system, while reducing the tedious operation of repairing the original insulation layer.

[0048] In any of the above schemes, it is preferred that the open tongue and groove structure is arranged at the longitudinal seam of two adjacent metal-faced sandwich panels 4; the open tongue and groove structure is composed of a female structure 8 arranged on one side of the metal-faced sandwich panel 4 and a male structure 9 arranged on the corresponding side of the adjacent metal-faced sandwich panel 4, the female structure 8 and the male structure 9 cooperate with each other and both are arranged to penetrate the corresponding metal-faced sandwich panel 4 in the thickness direction, the female structure 8 and the male structure 9 successively pass through the inner metal panel 401, the insulation material layer 402, and the outer metal panel 403 thereon along the thickness direction of the metal-faced sandwich panel 4; the two mutually cooperating inner metal panels 401 and the two mutually cooperating outer metal panels 403 at the end face positions of the female structure 8 and the male structure 9 are close to overlap and disconnected.

[0049] The outer metal panel of the female structure 8 extends outward for a certain distance to form a cantilevered cover plate (outer concave curled cover plate section 805), and then curls inward to the insulation material layer 402; this cantilevered cover plate overlaps the outer stepped metal panel (outer convex curled section 903) of the male structure 9, which can hide the inner mounting screws and achieve a better appearance effect.

[0050] A male port structure 9 is provided on one side of the metal-surface sandwich panel 4 , and a female port structure 8 is provided on the other opposite side.

[0051] The ends of the inner metal panel 401 and the outer metal panel 403 of the thermal insulation tongue and groove structure of the present invention are composited with the internal thermal insulation material layer 402 in a disconnected and discontinuous manner, which can block the heat flow from being transferred inward through the metal panel.

[0052] The female structure 8 includes an inner notch portion 801 opened on the inner side of the thermal insulation material layer 402 of the metal-faced sandwich panel 4, an outer notch portion 802 is provided on the thermal insulation material layer 402 outside the inner notch portion 801, and the thermal insulation material layer 402 outside the outer notch portion 802 protrudes toward one side of the male structure 9 and forms a protrusion 803.

[0053] The end of the inner metal panel 401 located at the inner notch portion 801 of the metal-faced sandwich panel 4 is curled and extends to the inside of the inner notch portion 801 to form an inner concave curling section 804 .

[0054] The end of the outer metal panel 403 located at the outer notch portion 802 of the metal-faced sandwich panel 4 is curled around the protrusion 803 and extends to the inside of the outer notch portion 802 to form an outer concave curled cover plate section 805 .

[0055] The male opening structure 9 includes a male opening extension portion 901 which is opened on the inner side of the thermal insulation material layer 402 of the metal-surface sandwich panel 4 and is matched with the inner notch portion 801 .

[0056] The end of the inner metal panel 401 located on the inner side of the male extension portion 901 is curled and extends toward the female structure 8 and to the interior of the inner notch portion 801 to form an inner convex curled section 902 that overlaps and engages with the inner concave curled section 804 .

[0057] The end of the inner metal panel 401 located outside the male extension portion 901 is curled and extends toward the female structure 8 and to the inside of the outer notch portion 802 to form an outer convex curled section 903 that overlaps and fits with the outer concave curled cover plate section 805.

[0058] The overlapping portion of the end surfaces of the inner layer concave curling section 804 and the inner layer convex curling section 902 forms a “((”-shaped arc structure.

[0059] The overlapping portion between the end surfaces of the outer concave curled cover plate section 805 and the outer convex curled section 903 forms a "Σ"-shaped structure.

[0060] In any of the above solutions, it is preferred that the flat seams 11 of the metal-surface sandwich panels 4 are filled with thermal insulation material and sealed with sealant before metal fasteners 12 are installed.

[0061] After filling each flat seam with insulation material (such as glass wool), apply sealant and then install the metal fasteners 12.

[0062] In any of the above solutions, preferably, the heat-insulating material 14 filled in the flat seam 11 includes but is not limited to glass wool.

[0063] The heat-insulating material 14 filled in the groove 5 includes but is not limited to rock wool and glass wool.

[0064] In any of the above schemes, it is preferred that the anchor assembly 6 is a metal anchor assembly; the anchor assembly 6 includes a wall connection part 601 and a plate connection part 602, the wall connection part 601 is fixedly connected to the base wall 1 by an expansion bolt 7 passing through a through hole thereon, and the plate connection part 602 is fixedly connected to the metal-faced sandwich panel 4 by a self-tapping screw 10 passing through a through hole thereon.

[0065] In any of the above solutions, preferably, the end of the wall connecting portion 601 is bent to form a rectangular closed structure.

[0066] From the above, it can be seen that the system is composed of a base wall 1, a wall insulation layer 2, a finishing layer 3, a metal anchoring assembly, and an open metal-surface sandwich panel 4 from the inside to the outside.

[0067] According to the installation requirements, a part of the insulation layer of the existing building is removed until the base wall 1. The metal anchor assembly is fixed to the base wall 1 with expansion bolts 7, and the metal surface sandwich panel 4 is fixed to the metal anchor assembly 6 with self-tapping screws. The metal surface sandwich panel 4 directly has an open tongue and groove structure, which can achieve the self-sealing effect and effectively solve the influence of cold bridges. The rear part is tightly fitted with the insulation layer of the existing building under the installation pressure of the self-tapping screws 10, so that the entire system can achieve a cavity-free structural system.

[0068] After installation, the original insulation system was reinforced and a new insulation layer structure was added.

[0069] The construction steps such as removing the insulation layer are saved. At the same time, the original insulation layer is sealed inside the metal-surface sandwich panel 4 under the action of the new insulation system, which can also achieve the insulation effect. The installed system realizes the double-layer insulation effect, which increases the insulation effect of the original insulation system while reducing the effect of re-repair.

[0070] The metal face sandwich panel 4-point hanging exterior wall insulation system uses the metal face sandwich panel 4 as the decorative surface layer and the metal anchoring assembly as the point hanging support. Without removing the original wall decoration layer, the rear anchoring assembly 6 is used to anchor the wall at multiple points to form an insulation decorative exterior wall system.

[0071] The metal face sandwich panel 4 tongue and groove adopts an open structure, and the metal face sandwich panel 4 open edge closing method effectively solves the edge pressure cold bridge problem and improves the overall thermal insulation performance of the exterior wall.

[0072] The size of the installation hole opened on the surface of the insulation layer is larger than the size of the metal anchor component. After installation, other insulation materials (such as rock wool, glass wool) can be used to fill the gap.

[0073] After the whole system is installed, the metal face sandwich panel 4 is sealed with metal fasteners and sealant at the transverse seams, and the vertical seams are self-sealed with a tongue-and-groove structure to achieve a sealed structure of the whole system. In addition, the metal face sandwich panel 4 fixed with a metal anchor assembly can be installed vertically or horizontally.

[0074] In any of the above schemes, it is preferred that the plate structure adopted by the metal-faced sandwich panel 4 includes but is not limited to a double-sided tongue-and-groove metal-faced sandwich panel, a four-sided tongue-and-groove metal-faced sandwich panel, and a box-shaped metal-faced sandwich panel.

[0075] The double-sided tongue-and-groove metal-faced sandwich panels, the four-sided tongue-and-groove metal-faced sandwich panels, and the box-shaped metal-faced sandwich panels adopt the plate structure of the metal-faced sandwich panels recorded in the patent application previously applied by the applicant, which is named: a metal-faced sandwich panel point-hung exterior wall system.
