Description

Technical Field

[0001] This invention relates to the field of environmental engineering, specifically to a method for assembling a junction box inside a pre-drilled hole in a wall. Background Technology

[0002] Holes and gaps in walls significantly impact sound insulation performance. The better the wall's sound insulation, the more pronounced the effect of these gaps. For example, gaps in doors and windows, or pipes penetrating the wall, all contribute to a decrease in sound insulation. According to sound insulation theory, the larger the area of ​​a hole or gap, the greater its impact on the wall's sound insulation. Even if the original wall's sound insulation exceeds 60 dB, the presence of even 1‰ of porosity will reduce the wall's sound insulation to no more than 30 dB. Therefore, porosity can significantly reduce the sound insulation of a soundproof structure, especially for high-insulation walls (greater than 55 dB), where any gap can cause a sharp drop in sound insulation. For ease of use, walls often need to accommodate both high-voltage and low-voltage electrical wires. This is achieved by pre-installing a conduit within the wall, through which the wires are run. When a high level of sound insulation is required in a wall, gaps will remain between the through-holes of these pipes and the wall, thus reducing the wall's sound insulation. Currently, there is a lack of effective solutions. Summary of the Invention

[0003] The purpose of this invention is to provide a method for assembling a wiring box inside a pre-drilled hole in a wall, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for assembling a junction box within a pre-drilled hole in a wall, comprising the following specific steps:

[0005] S1: A rectangular junction box with open ends is formed by welding steel plates. The first conduit is welded to the inner wall of the top of the box. Rubber positioning strips are symmetrically pasted at the center of the top and bottom surfaces of the box.

[0006] S2: Reserve a hole in the wall for the box to be embedded, and embed a second conduit in the wall at the position corresponding to the bottom inner wall of the box, which is staggered from the first conduit;

[0007] S3: Push the box into the pre-drilled hole in the wall. Due to the presence of the rubber positioning strip, the upper and lower sides of the box form a gap cavity with the inner wall of the pre-drilled hole. Fill the gap cavity with sealant to form a sealed structure.

[0008] S4: Prepare a soundproofing plug, cut a first clearance groove on the top surface of the soundproofing plug for the first conduit to be inserted, and cut a second clearance groove on the side of the soundproofing plug facing the wall for the power supply line to pass through.

[0009] S5: After the wires are installed through the first conduit and the second conduit, fill the first conduit and the second conduit with expanding foam, and then embed the sound insulation plug into the box.

[0010] S6: Cover the exposed surface of the box with a cover plate and secure it with bolts.

[0011] Preferably, in step S1, the rubber positioning strip is cut at the corner facing the reserved hole to form a guide slope.

[0012] Preferably, the outer end of the first conduit is flush with the exposed surface of the box, and the inner end of the conduit is spaced with the inner wall of the pre-reserved hole in the wall to form a cavity for the power supply line.

[0016] S43: A third sound-absorbing layer is pasted on both sides of the above composite sound-absorbing block to form a sound-insulating plug that fits the internal cavity space of the box.

[0017] Preferably, the first sound-absorbing layer is made of glass wool, the second sound-absorbing layer is made of polyester fiber sound-absorbing cotton, and the third sound-absorbing layer is made of melamine foam.

[0022] 2. Rubber positioning strips are attached to the top and bottom surfaces of the box to form a gap cavity between the box and the pre-drilled hole in the wall, which facilitates the filling of sealant and ensures a good seal between the box and the pre-drilled hole.

Rubber positioning strips 4 are symmetrically pasted at the center of the upper and lower sides of the box 1. The corner of the rubber positioning strips 4 facing the reserved hole is cut to form a guide slope 5.

[0034] The outer end of the first conduit 2 is flush with the exposed surface of the box 1, and its inner end is spaced with the inner wall of the reserved hole in the wall to form a cavity for the power supply line.

[0035] S2: A reserved hole is reserved in the wall for the box 1 to be embedded, and a second conduit 3 is embedded in the wall at the position corresponding to the bottom inner wall of the box 2, which is staggered from the first conduit 2.

[0036] S3: Push the box 1 into the reserved hole in the wall. Due to the presence of the rubber positioning strip 4, the upper and lower sides of the box 1 form a gap cavity 6 with the inner wall of the reserved hole. Fill the gap cavity 6 with sealant to form a sealed structure.

[0037] S4: Prepare the sound-insulating plug 7. The specific preparation method of the sound-insulating plug 7 is as follows:

[0038] S41: Fold the first sound-absorbing layer 8 times to form multiple "V" shaped structures;

[0039] S42: Fill the "V"-shaped cavity of the first sound-absorbing layer 8 with the second sound-absorbing layer 9 and bond it together with adhesive to form a composite sound-absorbing block;

[0040] S43: A third sound-absorbing layer 10 is attached to both sides of the above composite sound-absorbing block to form a sound-insulating plug 7 that is adapted to the inner cavity space of the box 1.

[0041] The first sound-absorbing layer 8 is made of glass wool, the second sound-absorbing layer 9 is made of polyester fiber sound-absorbing cotton, and the third sound-absorbing layer 10 is made of melamine foam.

[0042] A first clearance groove 11 for the first conduit 2 to be embedded is cut on the top surface of the sound insulation block 7, and a second clearance groove 12 for the power supply line to pass through is cut on the side of the sound insulation block 7 facing the wall.

[0043] S5: After the wires are threaded through the first conduit 2 and the second conduit 3, foaming agent is filled into the first conduit 2 and the second conduit 3, and then the sound insulation plug 7 is embedded into the box 1.

[0044] S6: Cover the exposed surface of the box 1 with a cover plate 13 and fix it with bolts. The cover plate 13 has a through hole that is aligned with the first conduit 2.
