Because the overall panel is installed in a matched mode, the vertical and flat quality of the whole wall surface is high. The aluminum membrane plate 2 and the aluminum back edge 4 form an integral aluminum plate reinforcing system, the application range is improved, and if concrete structures such as constructional columns and the like are arranged between the ALC prefabricated plates, namely the ALC plates 1, only a counter-pull screw rod needs to be additionally arranged in a concrete area for reinforcement, so that the construction is convenient; for example, the aluminum diaphragm plates 2 on both sides of the ALC plate 1 are reinforced by the through-wall tie 201, and further, the aluminum diaphragm plates 2 on both sides of the ALC plate 1 are reinforced by the through-wall tie 201 passing through the rivet sheet 202. Furthermore, it is possible to further arrange the through-wall tension rod 201 between the upper and lower structural beams 3. Further, the ALC board 1 is arranged in the primary structure to be a structure for penetrating construction, so that the installation time of the secondary structure is saved, and the working efficiency is improved. A seamless structure is formed between the top of the ALC board 1 and the main body structure, namely the top of the ALC board 1 and the main body structure are poured into a whole, so that the cohesiveness between the top of the ALC board 1 and the main body structure is improved; namely, the construction structure is finished by one-time pouring, no gap exists at the top of the ALC plate 1, and the bonding property is good, so that the crack between different materials can be well controlled. When concrete structures such as constructional columns are arranged between the ALC boards 1, the ALC boards are reinforced and connected in the concrete area through the opposite-pulling screw rods.

In particular, the ALC board 1 can be hoisted in place through a vertical transportation tool.
It can also be specific that the vertical transportation means adopts a tower crane.
Specifically, when the aluminum laminates 2 on the two sides of the ALC board 1 are subjected to tie reinforcement, the aluminum laminates 2 on the two sides are subjected to tie reinforcement through the wall-through tie rods 201.
Specifically, when the aluminum laminates 2 on the two sides of the ALC board 1 are subjected to tie reinforcement through the wall-through tie 201, the wall-through tie 201 penetrates through the rivet sheet 202 to perform tie reinforcement on the aluminum laminates 2 on the two sides.
