[0021] Embodiment:

[0022] As shown in the accompanying drawings, a specific implementation mode of an ultra-low energy consumption prefabricated thermal insulation wall of the present utility model mainly includes a wall body, which is composed of a plurality of prefabricated wall panels stacked together. Each prefabricated wall panel includes a wall plate body 1. The wall plate bodies 1 of two adjacent prefabricated wall panels on the left and right are connected through a plug-in mechanism. The plug-in mechanism includes a lower connecting seat 2 connected to the wall plate body 1 of one of the prefabricated wall panels, and an upper connecting head 3 connected to the wall plate body 1 of the other prefabricated wall panel and adapted to the lower connecting seat 2. The lower connecting seat 2 is provided with a steel bar 2a, and the upper connecting head 3 is provided with a perforation 3a penetrating up and down. The steel bar 2a is inserted into the perforation 3a to realize the connection of the two prefabricated wall panels.

[0023] In this embodiment, taking Figure 1 the shown thermal insulation wall structure as an example, there are two layers of prefabricated wall panels, with four in each layer. The structure of the leftmost prefabricated wall panel is as shown in Figure 2 . A lower connecting seat 2 is integrally formed at the lower right end of the wall plate body 1, and the lower connecting seat 2 is provided with a steel bar 2a. The structures of the middle two prefabricated wall panels are as shown in Figure 3 . An upper connecting head 3 is integrally formed at the upper left end of the wall plate body 1, the upper connecting head 3 is provided with a perforation 3a, a lower connecting seat 2 is integrally formed at the lower right end of the wall plate body 1, and the lower connecting seat 2 is provided with a steel bar 2a. The structure of the rightmost prefabricated wall panel is as shown in Figure 4 . An upper connecting head 3 is integrally formed at the upper left end of the wall plate body 1, and the upper connecting head 3 is provided with a perforation 3a.

[0024] The four precast wall panels on each layer can be quickly connected by means of up-and-down insertion. After the lower connecting seat 2 is inserted into the upper connecting head 3, a cuboid structure is formed, and the outer surface of the cuboid structure is flush with the outer surface of the wall panel body 1 of the two inserted precast wall panels. Further, the size of the steel bar 2a on the lower connecting seat 2 is smaller than the size of the through hole 3a in the upper connecting head 3, so as to avoid excessive friction and make the insertion smoother. The length of the steel bar 2a is not higher than the height of the through hole 3a, and the through hole 3a is filled with concrete wrapping the steel bar 2a, which can ensure a more firm connection between the two precast wall panels.

[0025] In this embodiment, two heat insulation cavities 4 penetrating up and down are formed in the wall panel body 1 of each precast wall panel. The length of each heat insulation cavity 4 extends along the length direction of the wall panel body 1, and the two heat insulation cavities 4 are arranged side by side along the width direction of the wall panel body 1, as Figure 5 shown.

[0026] A partition device 5 is installed in each heat insulation cavity 4.

The five transverse connecting pieces 52 are respectively penetrated and fixed in the five-layer partition sheets 51, and the two ends of the transverse connecting pieces 52 are flush with the two ends of the partition sheets 51 respectively; the six longitudinal connecting pieces 53 are arranged at equal intervals, and each longitudinal connecting piece 53 passes through each layer of partition sheet 51 in turn and is connected to each transverse connecting piece 52. The top end of the longitudinal connecting piece 53 is flush with the top surface of the top-layer partition sheet 51, and the bottom end is flush with the bottom surface of the bottom-layer partition sheet 51.

[0027] The specific structure of the partition sheet 51 is that the partition sheet 51 includes seven soft sheet bodies 51a arranged at equal intervals in the transverse direction and six soft connecting strips 51b respectively connecting two adjacent soft sheet bodies 51a. The six longitudinal connecting pieces 53 correspond to the six soft connecting strips 51b one by one and respectively pass through the soft connecting strips 51b of each layer in turn.

[0028] In this embodiment, the outer contour of the partition sheet 51 is consistent with the inner contour of the heat insulation cavity 4, and the five-layer partition sheet 51 can divide the heat insulation cavity 4 into four non-communicating chambers. After the whole partition device 5 is placed into the heat insulation cavity 4, the top surface of the top-layer partition sheet 51 is flush with the top surface of the wall panel body 1 of the precast wall panel, and the bottom surface of the bottom-layer partition sheet 51 is flush with the bottom surface of the wall panel body 1 of the precast wall panel. The partition device 5 can isolate the flow of air, and the non-flowing air is a poor conductor of heat, ensuring that the insulation wall has better heat insulation performance and lower energy consumption.
