Description

Technical Field

[0001] This utility model relates to the field of soundproof wall technology, and in particular to a soundproof wall for building construction. Background Technology

[0002] However, in the existing technology, the installation of soundproof walls usually involves lightweight keel and sound insulation cotton on the wall. The keel is used to support the sound insulation cotton. After installation, foam glue is used to fix the sponge, and the keel is fixed with bolts. Then, cement is laid on the outside of the sound insulation cotton.

[0003] However, bolts are rigid connectors. When they directly penetrate the keel and are fixed to the wall, they form a continuous rigid path that creates a sound bridge. This allows sound waves to propagate efficiently through the bolts and keel, causing noise to bypass the sound insulation material and reducing the overall sound insulation effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem of acoustic bridging that easily occurs when bolts are used to fix the keel in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a soundproof wall for building construction, comprising a wall body, a keel, and sound insulation cotton, wherein the keel is set on the wall body by a first bolt, the sound insulation cotton is laid on the wall body between adjacent keels, and the side of the sound insulation cotton away from the wall body is provided with a cement layer, characterized in that an inner sound insulation board and an outer sound insulation board are respectively provided on both sides of the keel, the end face of the sound insulation cotton is located between the inner sound insulation board, the outer sound insulation board and one side of the keel, the outer sound insulation board is assembled and connected to the keel by a second bolt, and the end of the second bolt away from the keel is provided with a sound insulation cap.

[0006] In a preferred embodiment, the keel is arranged in an I-shape, and the inner sound insulation panel and the outer sound insulation panel have the same structure and are symmetrically arranged on both sides of the keel.

[0007] In a preferred embodiment, the inner and outer sound insulation panels are provided with retaining strips on both sides facing the sound insulation cotton, and the sound insulation cotton is provided with slots on both sides that are adapted to the retaining strips. The cooperation between the retaining strips and the slots ensures that the sound insulation cotton is installed more stably.

[0008] In a preferred embodiment, the outer sound insulation plate is provided with a threaded hole for the second bolt to pass through, and a limiting sleeve is provided outside the outer sound insulation plate at the threaded hole. The sound insulation cap is threadedly sleeved outside the limiting sleeve. After the second bolt is installed, the second bolt can be protected by threading the sound insulation cap onto the limiting sleeve.

[0009] In a preferred embodiment, the inner sound insulation panel has a hollow structure.

[0010] In a preferred embodiment, the inner sound insulation panel has multiple sound-absorbing blocks on both sides, and the surface of the sound-absorbing blocks has multiple sound-absorbing holes. When some sound enters the outer or inner sound insulation panel, the sound can be reflected multiple times on the sound-absorbing blocks and continuously weakened, thereby reducing noise.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This utility model uses the cooperation of the first bolt and the second bolt to ensure that the two bolts do not come into contact with each other, which can prevent sound from being directly transmitted to the wall through the bolts via the sound bridge effect. In addition, inner sound insulation boards and outer sound insulation boards are laid on both sides of the keel, and the sides are filled with sound insulation cotton, so that the keel is completely wrapped inside, which can effectively reduce the possibility of sound propagation on the keel. The sound insulation cap is set to further prevent sound from being transmitted through the exposed part of the second bolt. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a soundproof wall for building construction, including a wall body 1, a keel 2 and sound insulation cotton 3. The keel 2 is set on the wall body 1 by a first bolt 4. The sound insulation cotton 3 is laid on the wall body 1 between adjacent keels 2. The side of the sound insulation cotton 3 away from the wall body 1 is provided with a cement layer 5. The two sides of the keel 2 are respectively provided with an inner sound insulation board 6 and an outer sound insulation board 7. The end face of the sound insulation cotton 3 is located between the inner sound insulation board 6, the outer sound insulation board 7 and one side of the keel 2. The outer sound insulation board 7 is assembled and connected to the keel 2 by a second bolt 8. The end of the second bolt 8 away from the keel 2 is provided with a sound insulation cap 9.

[0020] like Figure 1-3 As shown, the keel 2 is arranged in an I-shape, and the inner sound insulation panel 6 and the outer sound insulation panel 7 have the same structure and are symmetrically arranged on both sides of the keel 2.

[0021] like Figure 1-3 As shown, the inner sound insulation panel 6 and the outer sound insulation panel 7 are respectively provided with a retaining strip 10 on both sides facing the sound insulation cotton 3. The sound insulation cotton 3 is provided with a slot 11 on both sides that is compatible with the retaining strip 10. The cooperation between the retaining strip 10 and the slot 11 ensures that the sound insulation cotton 3 is installed more stably.

[0022] like Figure 1-3 As shown, the outer sound insulation plate 7 is provided with a threaded hole 12 for the second bolt 8 to pass through. A limiting sleeve 13 is provided on the outside of the outer sound insulation plate 7 at the threaded hole 12. The sound insulation cap 9 is threaded on the outside of the limiting sleeve 13. After the second bolt 8 is installed, the second bolt 8 can be protected by threading the sound insulation cap 9 on the limiting sleeve 13.

[0023] like Figure 1-3 As shown, the inner sound insulation panel 6 has a hollow structure.

[0024] like Figure 1-3 As shown, the inner sound insulation panel 6 has multiple sound-absorbing blocks 14 on both sides, and multiple sound-absorbing holes 15 on the surface of the sound-absorbing blocks 14.

[0025] Working principle: During the installation of the soundproof wall, the inner soundproof panel 6 and the keel 2 are fixed to the wall 1 by the first bolt 4. Then, the soundproof cotton 3 is laid on the wall 1, with its end face filling between the inner soundproof panel 6 and one side of the keel 2, and fixed with foam adhesive. The outer soundproof panel 7 is placed on the side wall of the keel 2, with both ends overlapping the soundproof cotton 3 on both sides of the keel 2. The soundproof cotton 3 and the outer soundproof panel 7 are also fixed with foam adhesive. Then, the outer soundproof panel 7 is fixed to the keel 2 by the second bolt 8, and a soundproofing sleeve is fitted on the outer end of the second bolt 8. The cap 9 prevents the second bolt 8 from being exposed. The use of the first bolt 4 and the second bolt 8 together ensures that the two bolts do not contact each other, preventing sound from being directly transmitted to the wall 1 through the bolts via the sound bridge effect. In addition, inner sound insulation board 6 and outer sound insulation board 7 are laid on both sides of the keel 2, and the sides are filled with sound insulation cotton 3, so that the keel 2 is completely wrapped inside, which can effectively reduce the possibility of sound propagation on the keel 2. The setting of the sound insulation cap 9 further prevents sound from being transmitted through the exposed part of the second bolt 8.
