Description

Technical Field

[0001] This application relates to the technical field of building sound insulation, and in particular to a sound insulation wall keel member. Background Art

[0002] In the construction field, in order to improve the sound environment quality inside buildings, the application of sound insulation walls has gradually become popular.

[0003] Most of the existing sound insulation walls use light steel keels to build a basic fixing frame, fix materials such as fireproof boards, foamed cement boards, and gypsum boards on the light steel keels, then set wall panels outside the keels, and hang or apply decorative layers outside the wall panels. Although some sound insulation wall keel members on the market play a certain role in support and sound insulation, due to design limitations such as unreasonable structures, the sound insulation effect is not ideal and cannot meet the requirements of modern buildings for high-quality sound environments. Utility Model Content

[0004] In order to improve the sound insulation effect, the present utility model provides a sound insulation wall keel member.

[0005] The sound insulation wall keel member provided by the present utility model adopts the following technical solutions:

[0006] A sound insulation wall keel member includes a first placement groove, a second placement groove, and a middle placement groove. The first placement groove and the second placement groove are respectively arranged on both sides of the middle placement groove. The opening directions of the first placement groove, the second placement groove, and the middle placement groove are the same. A first sound insulation pad is connected to the outer edge side of the first placement groove far from the middle placement groove, and a second sound insulation pad is connected to the outer edge side of the second placement groove far from the middle placement groove.

[0007] By adopting the above technical solutions, when using this keel, both the first sound insulation pad and the second sound insulation pad are arranged between the keel and the wall panel. The first sound insulation pad and the second sound insulation pad can make the keel and the wall panel closely abut. When sound propagates, when it is transmitted from the wall panel to the keel, it first passes through the first sound insulation pad, and the first sound insulation pad reduces the resonance between the wall panel and the keel to attenuate the sound wave and improve the sound insulation effect. The sound continues to propagate and successively passes through the first placement groove, the middle placement groove, and the second placement groove. The first placement groove, the middle placement groove, and the second placement groove extend the sound propagation path, and further reduce the sound again to weaken it, improving the sound insulation effect. The sound continues to propagate. When it is transmitted from the keel to the wall panel, the second sound insulation pad attenuates the sound wave again and improves the sound insulation effect again.

[0008] Preferably, the first placement groove, the middle placement groove, and the second placement groove are integrally formed by folding a metal plate.

[0009] By adopting the above technical solutions, the production efficiency of the keel is improved. At the same time, the structural stability and sound insulation performance of the keel components are enhanced.

[0010] Preferably, the structures of the first placement groove and the second placement groove are symmetrical. The first placement groove includes a first inner plate, a first bottom plate, and a first outer plate. The first inner plate, the first bottom plate, and the first outer plate are sequentially and continuously arranged and are continuously and perpendicularly arranged. The first inner plate is connected to the middle placement groove.

[0011] By adopting the above technical solutions, the first inner plate, the first bottom plate, and the first outer plate form a rectangular groove, which is convenient for placing sound insulation materials subsequently.

[0012] Preferably, a first groove is provided on the first outer plate. The first groove is used for placing the first sound insulation pad, and the top of the first sound insulation pad protrudes from the side wall of the first outer plate.

[0013] By adopting the above technical solutions, the first groove facilitates positioning the installation position of the first sound insulation pad. And when the wall panel abuts against the first sound insulation pad, the first sound insulation pad is slightly deformed, which can enable the wall panel to abut against the keel, improve the stability of the sound insulation wall, and at the same time increase the sealing performance between the keel and the wall panel, enhancing the sound insulation effect.

[0014] Preferably, a plurality of groups of sound insulation holes are formed on the first bottom plate. The plurality of groups of sound insulation holes are arranged in sequence along the length direction of the first bottom plate. The sound insulation holes include a first hole, a second hole, and a third hole, and the first hole, the second hole, and the third hole are distributed in a triangular shape.

[0015] By adopting the above technical solutions, when sound passes through the holes, some sound waves will scatter, thus achieving an excellent sound insulation effect. The sound insulation holes are arranged in a triangular layout, which not only ensures the structural strength of the component but also further enhances the sound insulation performance.

[0016] Preferably, the first placement groove further includes a first bending plate. The first bending plate includes a horizontal portion and a vertical portion. The horizontal portion and the vertical portion are integrally formed. The horizontal portion is connected to the first outer plate and is perpendicularly arranged with respect to the first outer plate. The vertical portion extends from the horizontal portion towards the direction close to the first bottom plate.

[0017] By adopting the above technical solutions, the bending plate can position the filling material filled into the keel gap subsequently. In this way, when the keel is used in cooperation with other material plates, the bending plate can serve as the fixed edge of these plates.

[0018] Preferably, the middle placement groove includes a first partition board, a middle bottom board, and a second partition board. The first partition board, the middle bottom board, and the second partition board are arranged continuously in sequence and are continuously and vertically arranged.

[0019] By adopting the above technical solution, the first partition board, the middle bottom board, and the second partition board form a rectangular groove, and the sound wave will not directly transmit from the first bottom board to the second bottom board. The first partition board and the second bottom board increase the propagation path of the sound wave and improve the sound insulation effect.

[0020] Preferably, a first groove is provided on the first bottom board. The second placement groove includes a second bottom board, and a second groove is formed on the second bottom board. The bottom of the first groove and the bottom of the second groove are both flush with the outer side wall of the middle bottom board. An installation groove is formed by the first groove, the second groove, and the middle bottom board. A sealing gasket is provided in the installation groove. The sealing gasket is connected to the first bottom board, the second bottom board, and the middle bottom board, and the sealing gasket protrudes from the first bottom board and the second bottom board.

[0021] By adopting the above technical solution, if there is no sealing gasket, there may be a gap between the keel and the wall panel, and the sound may directly pass through the gap bypassing the keel. The sealing gasket seals the gap between the keel and the wall panel, thereby improving the sound insulation effect.

[0022] In summary, the utility model has the following beneficial effects:

[0023] When using this keel, the first sound insulation pad and the second sound insulation pad are both arranged between the keel and the wall panel. The first sound insulation pad and the second sound insulation pad can make the keel and the wall panel closely abut. When the sound propagates, when it is transmitted from the wall panel to the keel, it first passes through the first sound insulation pad. The first sound insulation pad reduces the resonance between the wall panel and the keel to attenuate the sound wave and improve the sound insulation effect. The sound continues to propagate and passes through the first placement groove, the middle placement groove, and the second placement groove in sequence. The first placement groove, the middle placement groove, and the second placement groove extend the sound propagation path, and the sound is further attenuated again, improving the sound insulation effect. The sound continues to propagate. When it is transmitted from the keel to the wall panel, the second sound insulation pad attenuates the sound wave again and improves the sound insulation effect again.

[0033] A sound insulation wall keel member, referring to Figure 1 and Figure 2, including a first placement groove 1, a second placement groove 2, and a middle placement groove 3. The first placement groove 1 and the second placement groove 2 are respectively arranged on both sides of the middle placement groove 3. The opening directions of the first placement groove 1, the second placement groove 2, and the middle placement groove 3 are the same. A first sound insulation pad 4 is fixedly connected to the outer edge side of the first placement groove 1 away from the middle placement groove 3, and a second sound insulation pad 5 is fixedly connected to the outer edge side of the second placement groove 2 away from the middle placement groove 3.

[0034] During use, the first sound insulation pad 4 and the second sound insulation pad 5 can make the keel and the wall panel closely abut. When sound propagates, when it is transmitted from the wall panel to the keel, it first passes through the first sound insulation pad 4. The first sound insulation pad reduces the resonance between the wall panel and the keel to attenuate the sound wave and improve the sound insulation effect. The sound continues to propagate and passes through the first placement groove 1, the middle placement groove 3, and the second placement groove 2 in sequence. The first placement groove 1, the middle placement groove 3, and the second placement groove 2 extend the sound wave path, further reducing the sound again and improving the sound insulation effect. The sound continues to propagate. When it is transmitted from the keel to the wall panel, the second sound insulation pad 5 attenuates the sound wave again and improves the sound insulation effect again.

[0035] Refer to Figure 2 , the first placement groove 1, the middle placement groove 3, and the second placement groove 2 are integrally formed by folding a metal plate, which improves the structural stability and sound insulation performance of the keel member.

[0036] Refer to Figure 2 , in this embodiment, the structures of the second placement groove 2 and the first placement groove 1 are symmetrically arranged. Therefore, only the structure of the first placement groove 1 will be described in detail in this embodiment.

[0037] Refer to Figure 2 , the first placement groove 1 includes a first inner side plate 11, a first bottom plate 12, a first outer side, and a first bending plate 14. The first inner side plate 11, the first bottom plate 12, and the first outer side are sequentially and continuously connected, and are sequentially and continuously vertically arranged and have vertical folding angles in the same direction. The height of the first inner side plate 11 is less than the height of the first outer side plate 13. One end of the first inner side plate 11 away from the first bottom plate 12 is fixedly connected to the middle placement groove 3.

[0038] The first inner side plate 11, the first bottom plate 12, and the first outer side plate 13 form a rectangular groove, which is convenient for placing subsequent sound insulation materials.

[0039] Refer to Figure 2 , the first bending plate 14 includes a horizontal portion and a vertical portion, and the horizontal portion and the vertical portion are integrally formed. One end of the horizontal portion is fixedly connected to the end of the first outer side plate 13 away from the first bottom plate 12, and the horizontal portion is perpendicular to the first outer side plate 13. The vertical portion extends from the horizontal portion towards the direction close to the first bottom plate 12.

[0040] Refer to Figure 1, sound insulation holes 6 are formed in the first bottom plate 12. There are multiple groups of sound insulation holes 6, and the multiple groups of sound insulation holes 6 are arranged at equal intervals along the length direction of the first bottom plate 12. The sound insulation holes 6 include a first hole 61, a second hole 62, and a third hole 63, and the first hole 61, the second hole 62, and the third hole 63 are distributed in a triangular shape. Moreover, the length direction of the third hole 63 is parallel to the length direction of the first bottom plate 12 and is arranged close to the first inner side plate 11.

[0041] When sound propagates on the first bottom plate 12, when sound waves encounter the first hole 61, the second hole 62, and the third hole 63 during the propagation process, some sound waves will undergo a scattering phenomenon. Scattering causes the propagation direction of the sound waves to change, thereby weakening the energy of the sound waves in the original direction and achieving the purpose of sound insulation.

[0042] Refer to Figure 2 , a first groove 131 is provided on the first outer side plate 13, and the opening of the first groove 131 faces away from the first inner side plate 11. There are two first sound insulation pads 4 arranged in parallel, and the two sound insulation pads are arranged along the vertical direction and are both provided in the first groove 131. The first sound insulation pad 4 protrudes from the first outer side plate 13.

[0043] The first groove 131 facilitates positioning the installation position of the first sound insulation pad 4. And when the wall panel abuts against the first sound insulation pad 4, the first sound insulation pad 4 undergoes slight deformation, which can make the wall panel abut against the keel, improving the stability of the sound insulation wall, and at the same time increasing the sealing performance between the keel and the wall panel and enhancing the sound insulation effect.

[0044] Refer to Figure 2 , a first middle wire groove is provided inside the first groove 131, and the first middle wire groove is arranged between the two first sound insulation pads 4. The depth of the first middle wire groove is the same as the width of the horizontal section of the first bending plate 14. The first middle wire groove and the first bending plate 14 cooperate to limit the sound insulation material 9.

[0045] Refer to Figure 2 , the middle placement groove 3 includes a first partition 31, a middle bottom plate 32, and a second partition 33. The first partition 31, the middle bottom plate 32, and the second partition 33 are arranged continuously in sequence, and are continuously vertically arranged and have vertical folding angles in the same direction. One end of the first partition 31 away from the middle bottom plate 32 is fixedly connected to the first inner side plate 11, and one bottom end of the second partition 33 away from the middle bottom plate 32 is fixedly connected to the second inner side plate 21. The first partition 31 and the second partition 33 have the same height.

[0046] The first partition 31, the middle bottom plate 32, and the second partition 33 form a rectangular groove, and sound will not directly travel from the first bottom plate 12 to the second bottom plate 22. The first partition 31 and the second bottom plate 22 increase the sound propagation path and improve the sound insulation effect.

[0047] Refer to Figure 3, one end of the first bottom plate 12 close to the middle bottom plate 32 is provided with a first groove 71, and the surface of the first groove 71 close to the first inner side plate 11 is the bottom of the first groove 71. The second placement groove 2 includes a second bottom plate 22. One end of the second bottom plate 22 close to the middle bottom plate 32 is provided with a second groove 72, and the surface of the second groove 72 close to the second inner side plate 21 is the bottom of the second groove 72. The bottom of the first groove 71, the outer side wall of the middle bottom plate 32, and the bottom of the second groove 72 are all flush, and the first groove 71, the middle bottom plate 32, and the second groove 72 form an installation groove 7.

[0048] Refer to Figure 3 , a gasket 8 is provided in the installation groove 7, and the gasket 8 is fixedly connected to the first bottom plate 12, the second bottom plate 22, and the middle bottom plate 32. And the gasket 8 protrudes from the bottoms of the first bottom plate 12 and the second bottom plate 22.

[0049] If there is no gasket 8, there may be a gap between the keel and the wall panel, and then the air directly bypasses the keel. The gasket 8 seals the gap between the keel and the wall panel, thereby improving the sound insulation effect.

[0050] Refer to Figure 4 , sound insulation materials 9 are filled in both the first placement groove 1 and the second placement groove 2. The sound insulation materials 9 are made of glass wool or rock wool, etc.

[0051] The working principle of this application is as follows: When in use, sound propagates from one side of the keel member to the other side. The first sound insulation pad 4, the sound insulation holes 6, the first partition 31, the second partition 33, and the second sound insulation pad 5 weaken the sound wave in sequence, so that the keel plays a role in sound insulation. At the same time, the sound insulation materials 9 in the first placement groove 1 and the second placement groove 2 further improve the sound insulation effect.

[0052] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
