The method comprises the following steps:

referring to fig. 1, it is a block flow diagram of a method for processing a wall surface on the back of an embedded box in a wall according to an embodiment of the present invention. As shown in the figure, the method for processing the wall surface on the back surface of the embedded box body in the wall body comprises the following steps:

step S1, when the wall is built, the box body is positioned, leveled and fixed so as to be concealed in the wall body, and the gap between the periphery of the box body and the masonry of the wall body is filled with mortar to be compact; wherein, a vacant gap is arranged between the back of the box body and the outer surface of the wall body of the base layer filling plate 5.

Specifically, when the wall body 2 is built, along with the building of the wall body 2, namely the building of the wall body 2 to a preset height, the box body 1 can be positioned, adjusted, leveled and fixed; then, the wall body 2 is built continuously, so that the box body 1 is arranged in the wall body 2 in a concealed mode; finally, after the wall 2 is built or built to the upper side of the box body 1, the gap between the periphery of the box body 1 and the masonry of the wall 2 can be tightly filled with mortar, that is, a mortar layer (not shown in the figure) is formed in the gap between the periphery of the box body 1 and the masonry of the wall 2, so as to fill the gap between the periphery of the box body 1 and the masonry of the wall 2. The preset position may be determined according to actual conditions, and is not limited in this embodiment. Both the inner surface (the lower surface as shown in fig. 2) and the outer surface (the upper surface as shown in fig. 2) of the wall body 2 can be provided with a plastering layer 3, and the surface of the plastering layer 3, which is back to the wall body 2 (the upper surface of the plastering layer 3 at the upper side as shown in fig. 2 and the lower surface of the plastering layer 3 at the lower side) can be provided with a decorative surface layer 4; the decorative finish 4 may be a paint finish or a tile finish. In this embodiment, after the box body 1 is positioned, the front surface of the box body 1 may be flush with the outer surface of the decorative surface layer 4 disposed at the innermost layer of the inner surface of the wall body 2 (such as the lower surface of the lower decorative surface layer 4 shown in fig. 2), of course, the front surface of the box body 1 may also be protruded outside the decorative surface layer 4 disposed at the innermost layer of the inner surface of the wall body 2, which is not limited in this embodiment; a free gap is formed between the back surface of the box body 1 and the outer surface of the wall body 2, namely, the back surface of the box body 1 is concavely arranged in the wall body 2, so that the influence of the box body 1 on the aesthetic property of the wall body 2 is avoided, the thickness of the free gap can be determined according to the actual situation, and the thickness of the free gap is not limited in the embodiment. The box body 1 can be a metal box body such as a fire box, a distribution box and the like, and can also be other box bodies, and no limitation is made on the box body in the embodiment.

And a filling vacancy step S2, selecting a base layer filling plate to be bonded on the back surface of the box body according to the gap thickness of a vacancy gap between the back surface of the box body and the outer surface of the wall body, so that the outer surface of the base layer filling plate, which is opposite to the box body, is flush with the outer surface of the wall body, and fixing the connecting surface plate, the base layer filling plate and the box body firmly by using fixing rivets.

Specifically, first, a fiber cement pressure plate with a suitable thickness, that is, a thickness adapted to a gap thickness of a vacant gap between a back surface (an upper surface as shown in fig. 2) of the box 1 and an outer surface of the wall 2, is selected as the base layer reinforcing plate 5, the fiber cement pressure plate may be one layer or a plurality of layers, which is not limited in this embodiment, and the fiber cement pressure plate may be integrated and have a thickness adapted to the gap thickness, wherein the plurality of layers of fiber cement pressure plates may be bonded by the structural adhesive 10, or may be fixedly connected by other means, which is not limited in this embodiment; then, the base layer filling plate 5 can be firmly bonded with the box body 1 by using the structural adhesive 10, that is, a structural adhesive layer is arranged between the base layer filling plate 5 and the box body 1, so that the base layer filling plate 5 and the box body 1 are connected and fixed, that is, a vacant gap between the back surface of the box body 1 and the wall body 2 is filled by the base layer filling plate 5, and the outer surface (the upper surface shown in fig. 2) of the base layer filling plate 5 and the outer surface of the wall body 2 are arranged in parallel and level, so as to ensure the overall stability of the wall body; and finally, filling the gap between the base layer filling plate 5 and the wall body 2 tightly by adopting caulking paste 6. Wherein, adopt multilayer panel filling to connect fixedly, and each material joint gap adopts the sealant 6 caulking joint to fill tightly sealed promptly to overcome the poor problem of box back thin wall body sound insulation effect.
