[0028] The prefabricated electrical box assembly, the wall system and the installation method of the wall system according to the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0029] Figure 1 is a structural schematic diagram of a prefabricated electrical box assembly provided by an embodiment of the present disclosure; Figure 2 It is a schematic diagram of an electrical box body and a connection angle bracket after installation provided by an embodiment of the present disclosure; Figure 3 is a top view of a prefabricated electrical box trough and a wall provided by an embodiment of the present disclosure; Figure 4 is a side view of a prefabricated electrical box trough and a wall provided in an embodiment of the present disclosure; Figure 5 is a schematic diagram of a wall system provided by an embodiment of the present disclosure; Figure 6 It is a flowchart of the installation method of the wall system provided in the embodiment of the present disclosure.

[0030] Figure 1 and Figure 2As shown, an embodiment of the present disclosure provides a prefabricated electrical box assembly, including: a prefabricated electrical box slot 101, prefabricated in a wall 400; an electrical box body 201, arranged in the prefabricated electrical box slot; a connecting angle code 301, one end of the connecting angle code is fixedly connected to one side of an end of the electrical box body away from the outside of the wall, and the other end of the connecting angle code is fixedly connected to the wall; a sound insulation cotton layer 202, wrapping the embedded surface of the electrical box body, and the embedded surface refers to the surface of the electrical box body embedded in the wall.

[0031] Specifically, the prefabricated electrical box slot is a prefabricated electrical box installation slot, which is an iron square slot with the slot opening facing the outside of the wall.

[0032] Sound insulation cotton, also known as sound insulation cotton, is a kind of fiber porous sound insulation material. There are a large number of tiny interconnected pores inside the sound insulation cotton material, so that the external sound waves will penetrate into the material along the pores, thereby rubbing against the material, converting the sound energy into heat energy, gradually consuming the energy, and achieving a sound insulation effect. Filling with sound insulation cotton can further enhance the sound insulation effect of partition wall products.

[0033] In the related art, electrical boxes, switch boxes, electrical pipes and other equipment need to be installed on the left and right sides of the partition wall, which will reduce the sound insulation performance of the partition wall. The prefabricated electrical box assembly in the embodiment of the present disclosure can improve the sound insulation performance of the partition wall. By adopting the technical solution of the embodiment of the present disclosure, the electrical box installation groove can be prefabricated in the factory that produces the wall according to industrial standards. In this way, there is no need to make grooves on site during the subsequent installation of the electrical box. In addition, by providing a sound insulation cotton layer, sound insulation measures are taken at the grooved part to ensure that the sound insulation of the partition wall meets the regulatory requirements. The prefabricated product can make the installation of the electrical box more convenient, and the sound insulation measures make the partition wall have a better sound insulation effect at the grooved part.

[0034] The prefabricated partition wall, the electrical box body and the connecting angle bracket with prefabricated electrical box installation slots can be prefabricated by the factory. Each component can be quickly assembled on site, and the components are convenient to transport. They can be assembled according to the on-site dimensions, which can avoid the problem that the factory customized dimensions do not match the on-site dimensions. It has the advantages of factory production standardization and flexibility, which is conducive to the production and installation of partition products. In addition, the use of sound insulation cotton layers can enhance the sound insulation performance of partition products.

[0035] like Figure 2 As shown, one end of the connecting angle code is fixedly connected to the electrical box body through a rivet 501, and the other end of the connecting angle code is fixedly connected to the wall through an expansion bolt 502.

[0036] A rivet is a nail-shaped object used to connect two parts or components with through holes. During the riveting process, the rivet uses its own deformation or interference to connect the riveted parts to form a whole. Rivets are widely used in connecting and riveting various objects, especially in situations where high-strength connections are required. In the construction field, rivets are often used to connect steel structures. In the disclosed embodiment, rivets are used to connect the angle bracket and the electrical box body with high strength.

[0037] Expansion bolts are usually composed of countersunk bolts, expansion tubes, flat washers, spring washers and hexagonal nuts. Expansion bolts can use the wedge-shaped slope to promote expansion to generate friction and grip force to achieve a fixing effect. When the bolt is tightened, the expansion tube is squeezed and stretched open, causing friction between it and the fixed body, thereby fixing the bolt to the wall. In the embodiment of the present disclosure, the expansion bolt can be used to firmly fix the connecting angle code on the wall.

[0038] Furthermore, if Figure 1 As shown, an aerogel cushion layer 102 and a protective layer 103 for protecting the aerogel cushion layer are sequentially stacked on the bottom and inner side of the wall of the prefabricated electrical box slot. Aerogel is a very light, high-porosity porous material, and its microstructure can be described as honeycomb, grid, etc. This material has the characteristics of low density, high porosity and extremely small pore size, so it has a unique sound insulation effect in sound wave propagation. During the propagation of sound waves, the microscopic pores of aerogel can act as obstacles, sound absorption and reflection. When sound waves hit the microscopic pores of aerogel, multiple reflections and refractions will occur, causing the sound wave energy to dissipate and absorb. In addition, the high porosity and extremely small pore size of aerogel can also play a role similar to a low-pass filter, absorbing high-frequency sound waves and reducing the frequency and intensity of noise. The provision of an aerogel cushion layer and a protective layer can further enhance the sound insulation performance of the partition wall at the slotted portion.

[0039] The protective layer may be a foamed polyvinyl chloride layer. The foamed polyvinyl chloride layer may be formed by a PVC (PolyVinylchloride) foam board. The PVC foam board is a fireproof material with excellent impact resistance and heat insulation properties, which can protect the aerogel cushion layer, thereby helping to enhance the sound insulation performance of the partition wall product.

[0040] like Figure 3 As shown, the prefabricated electrical box slot 101 is prefabricated in the wall 400 in the wall production factory. When the prefabricated electrical box slot is prefabricated, considering the household division of the partition wall, the following can be done: Figure 3 The offset design shown. Figure 4As shown, mounting holes are provided on the wall on both sides of the center line of the prefabricated electrical box slot 101. When installing the electrical box body, the electrical box body is first connected to the connecting angle bracket by rivets, and then the expansion bolts are inserted into the mounting holes to fix the connecting angle bracket to the wall. The installation process is fast, convenient and efficient.

[0041] The prefabricated electrical box assembly provided by the embodiment of the present disclosure can reduce the damage to the sound insulation performance of the partition wall caused by the grooving construction through the prefabricated electrical box installation groove in the wall and wrap the sound insulation cotton layer on the outside of the electrical box body, and can further enhance the sound insulation performance at the groove position of the electrical box by providing the sound insulation cotton layer.

[0042] like Figure 5 As shown, an embodiment of the present disclosure provides a wall system, which includes a partition wall, i.e., a wall 400, a decorative panel 700, and a prefabricated electrical box assembly in the above technical solution; wherein, a prefabricated electrical box slot 101 of the prefabricated electrical box assembly is prefabricated in the partition wall; and the decorative panel is arranged on the surface of the partition wall and is located on the side of the prefabricated electrical box assembly.

[0043] Specifically, the partition wall may be an ALC (Autoclaved Lightweight Concrete) wall. ALC is a lightweight concrete material made of raw materials such as cement, lime, gypsum, sand and aluminum powder. This material has the advantages of light weight, high strength, heat insulation, sound insulation, fire resistance and waterproofness, and is therefore widely used in the fields of construction, decoration, partitions, sound insulation, heat insulation and fire prevention. ALC has the advantages of light bulk density, good sound insulation and heat preservation effects, low cost and simple installation process, and is easy to transport and install during construction, with a low material loss rate and can greatly shorten the construction period. Prefabricating the electrical box installation groove in the ALC wall can make the installation of the prefabricated wall system simpler and have better sound insulation performance.

[0044] In the related art, electrical boxes, switch boxes, electrical pipes and other equipment need to be installed on the left and right sides of the partition wall, which will reduce the sound insulation performance of the partition wall. The use of the prefabricated electrical box assembly in the embodiment of the present disclosure can improve the sound insulation performance of the wall system.

[0045] like Figure 5 As shown, the outer surface of the electric box body of the prefabricated electric box assembly is flush with the outer surface of the decorative panel, and the notch of the prefabricated electric box slot is flush with the outer surface of the partition wall. The surface of the electric box body adjacent to the decorative panel is wrapped with a sound insulation cotton layer.

[0046] The outer surface of the prefabricated electric box assembly is flush with the outer surface of the decorative panel, and the notch of the prefabricated electric box slot is flush with the outer surface of the partition wall, which can make the junction between the electric box body and the wall more neat and improve the aesthetics of the electric box installation.

[0047] Part of the surface adjacent to the electrical box body and the decorative panel is wrapped with a sound insulation cotton layer, which can further enhance the sound insulation performance of the electrical box installation location.

[0048] The wall system provided in the embodiment of the present disclosure includes a prefabricated electrical box assembly. By prefabricating an electrical box installation groove in the wall and wrapping a sound insulation cotton layer on the outside of the electrical box body, the damage to the sound insulation performance of the partition wall caused by the grooving construction can be reduced through the prefabricated electrical box installation groove, and the sound insulation performance at the groove position of the electrical box can be further enhanced by providing a sound insulation cotton layer.

[0049] Figure 6 FIG. 1 is a flow chart of the installation method of the wall system provided by the embodiment of the present disclosure. Figure 6 As shown, the embodiment of the present disclosure provides an installation method of the wall system applied to the above technical solution, and the installation method includes:

[0050] Step S601, installing a partition wall with a prefabricated electrical box trough.

[0051] Specifically, the partition wall may be an ALC autoclaved lightweight concrete wall.

[0052] Step S602, installing the electrical box body connected to the connection angle bracket into the prefabricated electrical box slot.

[0053] Specifically, rivets can be used to fix the electrical box body and the connecting angle brackets.

[0054] Step S603, fixedly connecting the connecting angle bracket to the partition wall.

[0055] Specifically, expansion bolts can be used to fix the connection angle brackets to the partition wall. Figure 2 As shown, one end of the connecting angle code is fixedly connected to the electrical box body through a rivet 501, and the other end of the connecting angle code is fixedly connected to the wall through an expansion bolt 502.

[0056] By adopting the technical solution of the disclosed embodiment, since the installation groove of the electric box is prefabricated in the factory producing the wall according to industrial standards, there is no need to make grooves on site during the installation of the electric box. In addition, a sound insulation cotton layer is provided on the electric box body, and sound insulation measures can be taken at the grooved part to ensure that the sound insulation of the partition wall meets the regulatory requirements. The prefabricated product can make the installation of the electric box more convenient, and the sound insulation measures make the partition wall have a better sound insulation effect at the grooved part.

[0057] When installing the electrical box body, first connect the electrical box body and the connecting angle code through rivets, then insert the expansion bolts into the installation holes on the wall on both sides of the prefabricated electrical box slot, and fix the connecting angle code to the wall. The installation process is fast, convenient and efficient.

[0058] According to the installation method of the wall system provided by the embodiment of the present disclosure, the prefabricated electrical box assembly in the above technical solution is used. Since the electrical box installation groove is prefabricated in the wall and a sound insulation cotton layer is wrapped on the outside of the electrical box body, the damage to the sound insulation performance of the partition wall caused by the grooving construction can be reduced, and the sound insulation performance at the grooved position of the electrical box can be further enhanced.
