[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Reference Figure 1 and Figure 2 As shown, in the first aspect of the present invention, a building exterior wall structure is provided, comprising: a keel bracket 1, a metal insulation layer 2 and a perforated aluminum plate 3 arranged in sequence from the inside to the outside, and a conversion component 4, wherein the conversion component 4 is perpendicular to the keel bracket 1 and one end is fixedly connected to the keel bracket 1, the conversion component 4 is penetrated through the metal insulation layer 2, and the other end is fixedly connected to the perforated aluminum plate 3.

[0032] Specifically, the metal insulation layer 2 is fixed on the keel bracket 1, and the conversion component 4 is penetrated by the metal insulation layer 2, one end of which is fixedly connected to the keel bracket 1, and the other end is used to connect to the perforated aluminum plate 3, so that the metal insulation layer 2 and the perforated aluminum plate 3 share a set of keel brackets 1, thereby ensuring the compactness of the structure, while reducing the cost of the exterior wall and improving economic benefits.

[0033] It is understandable that the keel bracket 1 and the metal insulation layer 2 are both prefabricated finished parts, thereby improving the degree of assembly, shortening the construction period, and reducing the construction cost.

[0034] In the first aspect of the embodiment of the present invention, the keel bracket 1 includes a plurality of first keel members 11 and a plurality of second keel members 12 connected to each other, the length direction of the first keel member 11 is arranged along the vertical direction, and the plurality of first keel members 11 are arranged at intervals along the horizontal direction, the length direction of the second keel member 12 is arranged along the horizontal direction, and the plurality of second keel members 12 are arranged at intervals along the vertical direction, and the second keel members 12 and the first keel members 11 are staggered in a grid distribution.

[0035] In the first embodiment of the present invention, the distance between two adjacent first keel members 11 is 3m.

[0036] Specifically, the second keel members 12 and the first keel members 11 are staggered and arranged in a grid distribution, thereby ensuring the structural connection strength.

[0037] In the first aspect of the embodiment of the present invention, the metal insulation layer 2 includes a first metal layer, an insulation layer and a second metal layer arranged in sequence from the inside to the outside, the first metal layer, the insulation layer and the second metal layer are arranged integrally, the first metal layer is fixedly connected to the second keel member 12 by a first fastener, and the first metal layer is abutted against the first keel member 11.

[0038] Specifically, the metal insulation layer 2 is an integrated prefabricated structure. The arrangement of the first metal layer and the second metal layer ensures the structural strength. The insulation layer is an insulating rock wool material. The three-layer arrangement improves the insulation performance and effectively insulates. In addition, the first metal layer and the second metal layer are located on both sides of the insulation layer to improve the stability of the connection. The first metal layer is fixedly connected to the second keel member 12 by a first fastener.

[0039] It can be understood that the metal insulation layer 2 is provided with multiple pieces, and a vertical joint is formed between two adjacent metal insulation layers 2. The conversion component 4 is arranged in the vertical joint to be located between the two metal insulation layers 2, thereby avoiding damage to the metal insulation layer 2 and affecting the insulation performance. In addition, the vertical joint setting can effectively achieve waterproof and water-stopping performance. After installing the metal insulation layer 2, waterproof parts can be installed between the vertical joints. The waterproof part is a rubber strip, and the rubber strip has good elasticity. The size of the waterproof glue can be larger than the size of the vertical joint, thereby ensuring that the rubber strip is in a compressed state in the vertical joint to achieve sealing of the circumference of the vertical joint.

[0040] It is understandable that in order to ensure waterproof performance, waterproof glue can be applied on the outer periphery of the vertical joint, and there is a horizontal joint between the two metal insulation layers 2 along the vertical direction. The horizontal joint adopts a finished splicing node to improve the water-stopping effect.

[0041] In the first aspect of the embodiment of the present invention, the conversion component 4 includes a cantilevered corbel 41, and the cantilevered corbel 41 is provided in plurality, and the plurality of cantilevered corbels 41 are distributed in an array. Along the vertical direction, the spacing between two adjacent cantilevered corbels 41 is 1.25m, and along the horizontal direction, the spacing between two adjacent cantilevered corbels 41 is 3m.

[0042] In the first aspect embodiment of the present invention, one end of the cantilevered corbel 41 is fixedly connected to the outer side of the first keel member 11, and the conversion assembly 4 also includes an adapter 42, which is arranged at the other end of the cantilevered corbel 41, and the perforated aluminum plate 3 is fixedly connected to the cantilevered corbel 41 through the adapter 42.

[0043] In the first aspect of the embodiment of the present invention, the adapter 42 is a galvanized square tube, one side of the galvanized square tube is fixedly connected to the side of the other end of the cantilevered corbel 41 through a second fastener, and the other side of the galvanized square tube is fixedly connected to the perforated aluminum plate 3 through a third fastener.

[0044] Specifically, by setting the conversion component 4, the metal insulation layer 2 and the perforated aluminum plate 3 share a set of keel brackets 1, which reduces the use of the keel brackets 1 while ensuring the connection strength, reduces the cost, and ensures lightweight.

[0045] In the first embodiment of the present invention, a gasket is provided between the galvanized square tube and the perforated aluminum plate 3. Specifically, the provision of the gasket can ensure the stability of the connection, while avoiding damage caused by wear and tear, and effectively reducing costs.

[0046] In the first embodiment of the present invention, there is a spacing space between the inner side of the perforated aluminum plate 3 and the second metal plate.

[0047] Specifically, a spacing space is provided between the perforated aluminum plate 3 and the metal insulation layer 2, and the provision of the spacing space can effectively improve the thermal insulation performance.

[0048] In a second aspect, the present invention further provides a construction method for a building exterior wall structure, comprising the following steps:

[0049] On the main structure, embedded parts are installed every 3m in the horizontal direction;

[0050] Assembling the keel bracket 1, hoisting the keel bracket 1 to weld and install the first keel member 11 and the embedded member correspondingly;

[0051] According to the module of the perforated aluminum plate 3, the conversion assembly 4 is installed on the first keel member 11;
