Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation walls, and more specifically, to a thin sound insulation wall. Background Art

[0002] As people's living standards improve, their requirements for entertainment are getting higher and higher. Many families set up DJ rooms and karaoke rooms at home. However, DJ rooms and karaoke rooms often generate a lot of noise. If these entertainment systems are used at night, the sound noise will affect the rest of family members and even neighbors, causing disputes and even legal problems. Therefore, higher sound insulation requirements are required for rooms such as DJ rooms and karaoke rooms. However, the sound insulation requirements of the walls of existing houses during construction cannot meet the sound insulation requirements of DJ rooms and karaoke rooms.

[0003] Patent document CN221372554U discloses a soundproof wall for house construction, which belongs to the field of house sound insulation. It includes two groups of columns fixed to the roof and the floor. The two groups of columns are symmetrically arranged, and each group of columns is located in the same plane. A connecting frame is fixed between the columns, and gypsum boards are fixed on the sides of the two groups of columns respectively. A sound insulation layer is installed in the middle of the two groups of columns. The application has a novel design and a clever structure. The sound insulation layer is firmly fixed in the position between the two groups of columns through a fixing device, effectively preventing the sound insulation layer from falling in the wall, thereby greatly improving the service life of the sound insulation layer. At the same time, by providing the sound insulation layer, the transmission of sound is greatly weakened, greatly protecting personal privacy.

[0040] Furthermore, the acoustic black hole sound insulation board 1 is made of wood or high molecular polymer material.

[0041] The working principle of the above technical solution is:

[0042] Installing a thin soundproof wall on the inner wall of an existing house can greatly improve the sound insulation effect while occupying a smaller space. The following is an example of installing a thin soundproof wall on an indoor wall. Support beams are installed at a certain distance from the wall. Multiple support beams are arranged parallel to each other and in a vertical plane, so that the installed thin soundproof wall can remain vertical.

[0043] When installing support beams, the number of support beams is determined according to the height of the house, and 3-5 is generally selected. When the number of support beams is an even number, the support beams are symmetrically arranged up and down with the horizontal plane at the center position of the house height as the reference. When fixing the support beams on the ground and ceiling, leave a certain distance between the support beams and the wall. The cavity formed between the acoustic black hole sound insulation board 1 and the wall can also act as a sound insulation cavity. Drill holes at positions corresponding to the connection holes 9 on the bottom surface of the U-shaped beam 8 on the ground and ceiling, and fix them with expansion bolts. The U-shaped beam of the support beam is located on the side of the H-shaped beam away from the wall. When fixing the middle support beam, after determining the position of the support beam, it is opposite to the connection holes on the connecting plate on the wall adjacent to the wall. Drill holes at the corresponding positions and fix them with expansion bolts. During installation, start installing the support beam from the ground. After installation, insert the lower end of the acoustic black hole sound insulation board 1 into the groove of the H-beam 7 and fix it. The end face of the acoustic black hole sound insulation board 1 with the sound-absorbing hole 5 opened on the board body 4 is away from the wall. You can use adhesive to bond the acoustic black hole sound insulation board 1 to the H-beam 7, and then fill centrifugal glass wool between the U-beams. The centrifugal glass wool can be a centrifugal glass wool board or a centrifugal glass wool roll felt. Bond the centrifugal glass wool to the side of the black hole sound insulation board 1 away from the wall, and then fix the damping vibration reduction pad 11 to one side of the damping sound insulation board 2, and bond the damping sound insulation board 2 to the outer wall of the U-beam 8 away from the H-beam. When installing four thin sound insulation walls, columns are set between the ceiling and the floor near the corners, and the supporting beams are fixed on the columns. The thin sound insulation walls installed on each wall are the same as those on one wall. When the span of the house is large, one or more columns can be set at a certain distance from the wall surface to reduce the span of the supporting beam and improve the strength of the supporting beam.

[0044] The thickness of the acoustic black hole sound insulation board 1 is set to 16 mm, the thickness of the damping vibration damping pad is 3 mm, and the thickness of the damping sound insulation board is set to 16 mm. The damping sound insulation board is located on the side of the acoustic black hole sound insulation board 1 away from the wall. The damping vibration damping pad and the damping sound insulation board are existing technologies. You can choose the damping vibration damping pad and the damping sound insulation board in the existing technology with the thickness meeting the requirements and good sound insulation effect. The damping vibration damping pad is such as the environmentally friendly damping vibration damping pad disclosed in CN212889329U, and the damping sound insulation board is such as the damping sound insulation board that is easy to disassemble and assemble disclosed in CN218814901U.

[0045] The acoustic black hole sound insulation board 1 includes a board body 4. An array of sound-absorbing holes 5 are provided on one end surface of the board body 4. The sound-absorbing holes 5 are provided on the side wall of the acoustic black hole sound insulation board 1 away from the wall. The depth of the sound-absorbing holes 5 is less than the thickness of the board body 4. The sound-absorbing holes 5 are conical holes. The diameter of the conical holes gradually decreases from the surface of the board body 4 where the sound-absorbing holes 5 are provided to the inside of the board body 4. A plurality of wedge-shaped rings 6 are fixedly provided on the conical surface of the sound-absorbing hole 5 along the axial direction of the conical surface. The diameter of the inner hole of the wedge-shaped ring 6 gradually decreases from the outside to the inside of the sound-absorbing hole 5 as the wedge-shaped ring is positioned. The wedge-shaped structure is used to absorb sound.

[0046] The thickness of the wedge is from the outside to the inside, with the power function h = Ax m (where A is a non-zero constant, m≥2) decreases in form, the wave velocity of the bending wave will gradually decrease with the decrease of thickness. Under ideal circumstances, the wave velocity can be reduced to 0, that is, zero reflection of the wave can be achieved. The specific values ​​of A and m can be set according to the sound insulation requirements.

[0047] The wedge ring 6 is a circular ring with a central opening. The cross section of the wedge ring 6 is wedge-shaped. The thickness of the side of the wedge ring 6 away from the center is greater than the thickness of the side close to the center.

[0048] Beneficial effects of the above technical solution:

[0049] The thin sound insulation wall described in the utility model, compared with traditional bricks and gypsum boards, uses acoustic black hole sound insulation boards and damping sound insulation boards, which can achieve better sound insulation with a thinner thickness, and can achieve better sound insulation effect while occupying a smaller space. The centrifugal glass wool is lighter in weight, so that the sound insulation wall can adapt to more house structures.
