In addition, because the beam column connecting piece between the constructional column 8 and the upper floor 14 does not need the transverse connection ring beam 9, so can choose the beam column connecting piece that the side connecting plate 3 only has two through-holes two 5 for use, and the level height of these two through-holes two 5 is the same, so, can change the height of beam column connecting piece, thereby can finely tune the height of whole wall in a flexible way, for example, the height that the side connecting plate 3 has the beam column connecting piece of four through-holes two 5 is 200mm usually, the height that the side connecting plate 3 has the beam column connecting piece of two through-holes two 5 can be as low as 100mm, and then can effectively adjust the height of wall in 0 ~ 100 mm's scope during the construction, do benefit to the installation leveling of wall.

Step B, in order to ensure the stability of the wall framework, the wall boards 16 need to be assembled according to a first-to-last assembly principle, namely, after the wall boards 16 on the lower layer need to be assembled during assembly, the wall boards 16 on the corresponding upper layer can be assembled;

assembling the top wallboard 16 after assembling all the wallboards 16 at the bottom layer, when prefabricating the ring beam 9, eliminating the arrangement of convex ribs on the part of the connecting surface of the ring beam 9 corresponding to the rightmost wallboard 16 in advance, wherein the ring beam 9 is also the ring beam 9 transversely connected with the top constructional column 8, and when prefabricating the wallboard 16, correspondingly reducing the size of the rightmost wallboard 16 of the wall body in the length direction to ensure that the rightmost wallboard 16 of the wall body and the ring beam 9 form enough gaps, thereby facilitating the operation and construction of filling mortar, and the connecting surface of the wallboard 16 is correspondingly not provided with a groove;

the rib-free area of the ring beam 9 is removed, the wall boards 16 (the wall boards 16 without size reduction) at other positions of the wall body can be directly placed in the wall body framework, when the wall body is assembled, the wall board 16 at the leftmost position of the wall body is firstly directly placed in the rightmost area of the bottom layer, then the wall board 16 is horizontally pushed to the left side of the ring beam 9, when the wall body is horizontally pushed, the groove at the top end of the wall board 16 at the leftmost position of the wall body can be clamped with the rib of the ring beam 9, similarly, the wall boards 16 at other positions are sequentially assembled until the wall board 16 at the rightmost position of the bottom layer is placed and fixed through the pipe clamp 11, wherein before the wall board 16 is assembled, the pipe clamp 11 is nailed at the position which is about 100mm away from the right side surface at the upper end face and the lower end face of the wall board 16, after each wall board 16 is pushed to the preset area, the pipe clamp 11 is connected with the ring beam 9 or the ground beam 17 through the gun nail, the fixing of each wall board 16 is completed, as shown in figure 12, the pipe strap 11 is a connecting piece of a single flat plate fixed with a cylindrical column; after the bottom layer is filled with the five wall boards 16, the five wall boards 16 on the top layer are assembled according to the wall board 16 on the bottom layer, and only when the difference is that the upper end of the wall board 16 is fixedly connected with the upper floor 14, the connecting surface of the ring beam 9 without the convex rib corresponds to the lower end of the wall board 16.

The size of the wall board 16 at the rightmost side of the wall body is reduced, the whole length of the wall board 16 can be shortened, and a local notch can be designed at the connecting end of the wall board 16, as shown in fig. 13, for example, a rectangular notch is formed at the top end of the wall board 16 to form an L-shaped end;

if the wall plate 16 at the rightmost side of the wall body is designed to be shortened in overall length, and the overall length of the wall plate 16 is reduced by 100mm, a gap with the distance of 100mm is formed between the wall plate 16 and the ring beam 9, the top end of the wall plate 16 is connected and fixed with a beam-column connecting piece through a bent pipe clamp 12, as shown in fig. 14, the bent pipe clamp 12 is formed by adding a bent section at the flat tail end of a common pipe clamp 11, so that the wall plate 16 is conveniently fixed with the beam-column connecting piece or the constructional column 8;

if the wall plate 16 at the rightmost side of the wall body is a rectangular notch designed at the top section, the gap between the wall plate 16 and the ring beam 9 corresponds to the size of the notch, and the top end of the wall plate 16 can be connected and fixed with the ring beam 9 through the common pipe clamp 11.

After the wall boards 16 are assembled, gaps between the rightmost wall board 16 and the ring beam 9 and between the rightmost wall board and the floor slab are filled with ALC mortar, gaps between all beam-column connectors are filled with the ALC mortar, and a layer of ALC mortar is coated on the outer surfaces of all the beam-column connectors to wrap the outer surfaces of all the beam-column connectors, so that the surfaces of the beam-column connectors and the surface of the ring beam 9 or the ground beam 17 are kept flat.

In addition, the ring beam 9 can also select a part corresponding to any section of the wall panel 16 to cancel the arrangement of the convex rib, and can also complete the installation of the whole wall panel 16, for example, the ring beam 9 connecting surface corresponding to one wall panel 16 in the middle is selected, after the convex rib of the ring beam 9 is cancelled, the wall panels 16 at other positions can be transversely pushed from the middle to both sides to be clamped into the wall framework, and finally, the wall panel 16 with the reduced size is installed in the middle to complete the installation of the wall framework layer of the wall panel 16.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
