The connector 6 is connected to the first mesh reinforcement 21, the second mesh reinforcement 41, and the third mesh reinforcement 51.
Specifically, referring to fig. 3a to 3c, the vertical reinforcing bars 211 of the first reinforcing mesh 21 are disposed at a side close to the exterior sheathing panel 1, and the horizontal reinforcing bars 212 thereof are disposed at a side close to the insulating layer 3, so as to increase the anchoring depth of the connecting member 6 in the outer leaf panel 2 as much as possible.
Referring to fig. 4a and 4b, one end of the connecting member 6 extends into the outer blade 2 and is fixedly connected to the vertical steel bars 211 in the first steel bar mesh 21 through the nylon casting 7, one end of the connecting member 6 is wrapped by the nylon casting 7 and fixed by the nylon rods 8, and the wrapped length of the nylon casting 7 covers the length of the connecting member 6 extending into the outer blade 2, so as to block the cold and hot bridges and fix the connecting member 6 to the first steel bar mesh 21. Referring to fig. 5a to 5c, the nylon casting 7 includes a nylon outer frame 71 and a nylon inner core 72, the nylon outer frame 71 has a U-shaped groove 711, and the nylon inner core is embedded in the U-shaped groove 711 and forms a gap 73 with the bottom of the U-shaped groove 711 for embedding the short steel bar 9. First mounting holes 712 for mounting the nylon stick 8 are formed in two side walls of the U-shaped groove 711, an embedding groove 721 for embedding the connecting piece 6 is formed in one side, facing the inner wall of the U-shaped groove 711, of the nylon inner core 72, second mounting holes 722 for mounting the nylon stick 8 are formed in the position, corresponding to the first mounting holes 712, of the nylon inner core 72, and the nylon stick 8 penetrates into the first mounting holes 712 and the second mounting holes 722. Because the nylon casting 7 is made of nylon material, the elasticity is good, and the outer blade plate 2 can be allowed to deform at a certain temperature, so that the influence on the weather resistance of the wall body caused by too large restriction on the wall body and easy cracking can be avoided.
The connecting piece 6 is bound and connected with the second reinforcing mesh 41 in the post-cast concrete plate 4, and a certain distance is reserved between the second reinforcing mesh 41 and the heat insulation layer 3 so as to ensure that the second reinforcing mesh 41 is wrapped by concrete slurry on one side of the heat insulation layer 3 and increase the interface bonding force.
Further, the connector 6 is made of steel, preferably galvanized steel, and has different steel plate thicknesses, heights and lengths designed according to stress requirements, and the two ends thereof are respectively provided with reserved holes for anchoring connection with the first reinforcing mesh 21 and the third reinforcing mesh 41.

In practical engineering applications, the top and two sides of the outer blade 2 will have a larger size than the inner blade for horizontal and vertical joint connection, and the distance between the connecting members 6 should take this difference into account.
The thickness of the heat preservation layer 3 is suitable for thermal performance requirements of cold and severe cold areas, preferably, the thickness of the heat preservation layer 3 is 80-150 mm, and the concrete in the post-cast concrete plate 5 is self-compacting concrete not lower than C30 grade.
