[0039] The exterior wall includes an L-shaped corner plate 1 and two exterior wall panels 2, wherein the two exterior wall panels 2 are connected to both ends of the L-shaped corner plate 1 via a first connecting assembly;

[0040] The interior wall includes two vertically arranged interior wall panels 3, the ends of the two interior wall panels 3 are connected by a second connecting component, the two interior wall panels 3 are respectively arranged opposite to the two exterior walls, and the space between the exterior wall and the interior wall is filled with thermal insulation material or cast-in-place concrete.

[0041] A third connecting component is disposed between the outer wall and the inner wall, and is connected to the outer wall and the inner wall respectively.

[0042] In this embodiment, two exterior wall panels 2 are respectively arranged parallel to the two vertical parts of the L-shaped corner panel 1 and connected by a first connecting component to form an L-shaped exterior wall; two interior wall panels 3 are arranged vertically, with their adjacent ends connected by a second connecting component to form an L-shaped interior wall. The exterior and interior walls are then connected by a third connecting component, ensuring a stable connection between them. Insulation material or cast-in-place concrete is then filled between the exterior and interior walls to form a precast double-skin composite wall corner structure.

[0043] Preferably, in another embodiment of the present invention, the first connecting component includes:

[0044] Multiple first connecting plates 4 are arranged at intervals, and the first connecting plates 4 are attached to the outer side of the outer wall panel 2 and the L-shaped corner plate 1 and are fixedly connected to them.

[0045] In this embodiment, the two ends of the first connecting plate 4 are respectively attached to the outer sides of the outer wall panel 2 and the L-shaped corner plate 1, and then bolts are driven in. The first connecting plate 4 is fixed to the outer wall panel 2 and the L-shaped corner plate 1 by the bolts. Multiple first connecting plates 4 are distributed vertically to connect and fix the outer wall panel 2 and the L-shaped corner plate 1.

[0046] Preferably, in another embodiment of the present invention, the second connecting component includes:

[0047] Multiple L-shaped second connecting plates 5 are arranged at intervals, and the second connecting plates 5 are respectively attached to the outer side of the two inner wall panels 3 and fixedly connected to them.

[0048] In this embodiment, two inner wall panels 3 are vertically arranged, with one end close to each other to form a right angle of the inner wall. The second connecting plate 5 is L-shaped, with its two horizontal parts respectively attached to the outer sides of the two inner wall panels 3. Bolts are then driven in, and the second connecting plate 5 is connected and fixed to the two inner wall panels 3 by the bolts. Multiple second connecting plates 5 are distributed vertically to connect and fix the two inner wall panels 3.

[0049] Preferably, in another embodiment of the present invention, the third connecting component includes two sets of connecting units, and the inner wall panel 3 and the outer wall are connected to each other via the connecting units.

[0050] In this embodiment, two inner wall panels 3 and two outer wall panels 2 are arranged opposite to each other. Normally, the inner wall panel 3 is connected to its opposite outer wall panel 2. However, in this application, the inner wall panel 3 is connected to its outer wall and its perpendicular side through a connecting unit.
