Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a sound insulation wall of a residential building. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the acoustics of their living environment. The traditional residential wall structure has obvious deficiencies in sound insulation and cannot meet the sound insulation needs of modern houses. Therefore, in order to reduce the negative impact of noise on the surrounding environment and human life, most of the existing methods are to install a keel system on the base wall, and then fill the sound insulation material between the keels. Usually, a layer of sound insulation cotton is filled first, and then a layer of sound insulation board or sound insulation felt is covered, thus forming a multi-layered sound insulation structure. Although the above-mentioned sound insulation structure can isolate external noise to a certain extent and make the indoor space more quiet and comfortable, in the long-term use process, the sound insulation cotton, sound insulation board or sound insulation felt will inevitably be affected by the external air or water seepage in the wall and become damp. Once damp, it will not only reduce its service life, but also have a negative impact on their sound insulation and sound absorption effects, thereby affecting the acoustic performance of the entire wall. Summary of the invention

[0003] The utility model aims to provide a sound insulation wall for residential buildings in view of the defects of the prior art.

[0004] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0005] The soundproof wall of a residential building described in the utility model comprises a wall body, wherein two thin soundproof cavities filled with soundproof cotton are arranged in parallel in the thickness direction of the wall body, a thin sound-absorbing cavity filled with sound-absorbing cotton is sandwiched in the wall body between the two thin soundproof cavities, slots are opened on the thin soundproof cavity and the outer wall of the wall below the thin sound-absorbing cavity, a first connecting hole is arranged between the slot and the two thin soundproof cavities, a second connecting hole is arranged between the slot and the thin sound-absorbing cavity, a drying box is sealed and inserted in the slot, and a desiccant is filled in the drying box.

[0006] Furthermore, the slot opening is expanded outward to form a step groove of an annular structure. At this time, a connecting end plate covering the step groove is provided on the outer end surface of the drying box. The connecting end plate can be snapped into the step groove, and of course, it can also be fixed in the step groove by bolts. In addition, in order to ensure the sealing performance, an annular sealing groove should be opened in the circumferential direction in the step groove, and an annular sealing ring adapted to be connected with the annular sealing groove is provided on the connecting end plate.

[0007] Furthermore, sound-absorbing holes are evenly distributed on the wall between the thin sound-absorbing cavity and the thin sound-isolating cavity on both sides, which can further improve the sound insulation effect.

[0008] Furthermore, a plurality of reinforcing support columns are horizontally arranged between the two thin sound insulation cavities, so as to further enhance the service strength of the entire wall.

[0009] The utility model has the advantage that the sound insulation effect of the wall is effectively improved by the thin sound insulation cavity filled with sound insulation cotton and the thin sound absorption cavity filled with sound absorption cotton; at the same time, a drying box is sealed and inserted in the slot below the thin sound insulation cavity and the thin sound absorption cavity, and the slot is connected with the thin sound insulation cavity and the thin sound absorption cavity, so that the desiccant filled in the drying box can continuously dry the sound insulation cotton and the sound absorption cotton, thereby greatly improving the service life and performance of the sound insulation cotton and the sound absorption cotton; in addition, the drying box is sealed and inserted in the slot, which not only makes it easy to disassemble and replace the desiccant, but also effectively reduces the oxidation of the desiccant by air, thereby extending the service life of the desiccant.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] like Figure 1 , 2As shown, the residential building soundproof wall described in the utility model includes a wall 1, in which two thin soundproof cavities 2 filled with soundproof cotton are arranged in parallel along the thickness direction of the wall 1 (the soundproof cotton is a commercial product that can be directly purchased on the market, so it is not shown in the figure), and a thin sound-absorbing cavity 3 filled with sound-absorbing cotton is sandwiched in the wall 1 between the two thin soundproof cavities 2 (the sound-absorbing cotton is also a commercial product that can be directly purchased on the market, so it is not shown in the figure); the soundproof effect of the wall 1 can be effectively improved by the thin soundproof cavity 2 filled with soundproof cotton and the thin sound-absorbing cavity 3 filled with sound-absorbing cotton arranged in the wall 1. Of course, in order to further improve the soundproof effect of the wall 1, silencer holes 4 can also be evenly distributed on the wall 1 between the thin sound-absorbing cavity 3 and the thin soundproof cavities 2 on both sides, and the sound waves can be blocked and dispersed during the propagation process through the silencer holes 4, thereby achieving the purpose of further reducing noise. In order to further enhance the service strength of the entire wall 1, a plurality of reinforcing support columns 5 may be evenly distributed between the two thin sound insulation cavities 2. The axial direction of the reinforcing support columns 5 is consistent with the thickness direction of the wall 1. Each reinforcing support column 5 passes through the thin sound absorption cavity 3 and the two thin sound insulation cavities 2, thereby forming a multi-point internal support for the outer walls on both sides of the wall 1, thereby improving the supporting strength of the outer wall of the wall 1.

[0014] In addition, a slot 6 is provided on the outer wall of the wall 1 below the thin sound insulation cavity 2 and the thin sound absorption cavity 3. The slot 6 is opened inward from the outer wall of one side of the wall 1. A first connecting hole 7 is provided in the wall between the slot 6 and the two thin sound insulation cavities 2. A second connecting hole 8 is provided in the wall 1 between the slot 6 and the thin sound absorption cavity 3. The slot 6 can be connected with the thin sound insulation cavity 2 and the thin sound absorption cavity 3 through the first connecting hole 7 and the second connecting hole 8. At this time, a drying box 9 is sealed and inserted in the slot 6, and a desiccant 10 is filled in the drying box 9. The desiccant 10 can be one of iron powder, activated carbon, alkaline alumina, starch-based desiccant, cellulose-based desiccant and calcium chloride. While being practical and easy to purchase, the desiccant 10 can be used to continuously dry the sound insulation cotton in the thin sound insulation cavity 2 and the sound absorption cotton in the thin sound absorption cavity 3, thereby greatly improving the service life and performance of the sound insulation cotton and the sound absorption cotton, and extending the time for which the sound insulation effect of the wall 1 is maintained. Furthermore, in order to ensure the sealed insertion between the drying box 9 and the slot 6, a step groove 11 of an annular structure can be expanded outward at the notch of the slot 6. At this time, a connecting end plate 12 covering the step groove 11 is provided on the outer end surface of the drying box 9. The connecting end plate 12 can be adapted to be snapped into the step groove 11, and of course, it can also be fixed in the step groove 11 by bolts; in order to ensure the sealing performance, an annular sealing groove 13 should also be opened in the circumferential direction in the step groove 11, and an annular sealing ring 14 adapted to be connected with the annular sealing groove 13 is provided on the connecting end plate 12, which not only facilitates the disassembly of the drying box 9 to replace the desiccant 10, but also effectively reduces the oxidation of the desiccant 10 caused by the air entering the slot 6, thereby extending the service life of the desiccant 10.
