Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a sound insulation and sound absorption wall structure and a construction method thereof. Background Art

[0002] With the rapid development of social economy and the continuous improvement of people's material living standards, noise pollution has received more and more attention. According to relevant medical research, many invisible chronic diseases are related to noise that people ignore.

[0003] Existing walls are usually of fixed thickness. In cities, sound insulation layers can usually be set on walls to improve the sound insulation effect. However, when the noise is loud, the sound insulation effect cannot be enhanced. When used in the wild, the wall thickness is fixed, and the external volume is different at different times during the day and night. For example, near a stream, you may want to hear the sound of flowing water during the day, but at night you need to reduce noise for rest. However, the sound insulation effect of the wall is fixed and cannot be adjusted, which reduces the comfort of use. Summary of the invention

[0004] In order to facilitate the adjustment of the sound insulation effect of the wall, the present application provides a sound insulation and sound absorption wall structure and a construction method thereof.

[0005] The first method is that a sound insulation and sound absorption wall structure provided in this application adopts the following technical solution: A soundproof and sound-absorbing wall structure comprises a wall, an adjustment component and a plurality of soundproof components. A cavity is opened in the middle of the wall, an adjustment plate is slidably installed in the cavity, and the adjustment plate divides the cavity into an adjustment cavity and a soundproof cavity; all the soundproof components are arranged at intervals along the height direction of the partition wall cavity, and the two ends of the soundproof components are respectively hinged to the opposite sides of the partition wall cavity; the adjustment component is used to adjust the position of the adjustment plate in the cavity.

[0006] By adopting the above technical solution, at night, the adjustment component is used to change the position of the adjustment plate in the cavity, so that the distance between the two opposite sides of the sound insulation cavity can be reduced. At this time, the two ends of the sound insulation component are respectively rotated at the two opposite side walls of the sound insulation cavity, and the middle part of the sound insulation component is bent; when the external noise passes through the wall, the situation where the noise directly enters the room through the gap between two adjacent sound insulation components is reduced, that is, the obstacle of noise entering the room through the wall is increased, which plays a role in improving the sound insulation effect of the wall.

[0007] During the day, the adjustment component is used to change the position of the adjustment plate in the cavity, which can increase the distance between the two opposite sides of the sound insulation cavity; at this time, the extension directions of the two adjacent sound insulation components are in the same direction, which can allow external noise to enter the room directly through the gap between the two adjacent sound insulation components, that is, it has the effect of weakening the sound insulation of the wall, so as to facilitate the transmission of external noise into the room. Changing the position of the adjustment plate in the cavity by adjusting the component facilitates the adjustment of the sound insulation effect of the wall.

[0008] Optionally, the sound insulation assembly includes a first plate, a second plate and two sound insulation cottons, the first plate and the second plate are respectively hinged to the opposite sides of the sound insulation cavity, and the first plate and the second plate are rotationally connected on the sides close to each other; two sound insulation cottons are respectively installed on the first plate and the second plate; when the distance between the opposite sides of the sound insulation cavity is reduced, the connection between the first plate and the second plate enters between the adjacent first plate and the second plate.

[0009] By adopting the above technical solution, when the distance between the two opposite sides of the sound insulation cavity is reduced, the two ends of the first plate and the second plate rotate at the two opposite sides of the sound insulation cavity respectively, so that the hinge between the first plate and the second plate rotates and enters between the adjacent first plate and the second plate.

[0010] When external noise enters the room through the wall, the situation where the noise directly enters the room through the gap between two adjacent sound insulation components is reduced. That is, the noise enters the wall and is absorbed by the sound insulation cotton, and the noise passes through the gap between two adjacent sound insulation components and is absorbed by the sound insulation cotton, thereby playing a role in adjusting the sound insulation effect of the wall.

[0011] Optionally, the first plate and the second plate are connected via hinges, and all the hinges are located on the same side of all the sound insulation components.

[0012] By adopting the above technical solution, all hinges are arranged on the same side of all sound insulation components, so that the moving directions of the hinges of all sound insulation components can be kept the same, thereby reducing the situation where the hinges of two adjacent sound insulation components collide with each other and are damaged.

[0013] Optionally, the adjustment assembly includes a threaded rod, a rotating rod, a first gear and a second gear, wherein two ends of the threaded rod are rotatably installed on opposite sides of the cavity, and the adjustment plate is provided with a threaded hole, and the threaded rod is threadedly engaged with the threaded hole; the rotating rod is rotatably installed on the wall, and the first gear is rotatably installed in the adjustment cavity and connected to the rotating rod; the second gear is installed on the threaded rod, and the first gear and the second gear are meshed.

[0014] By adopting the above-mentioned technical solution, when it is necessary to adjust the position of the sound insulation board in the sound insulation cavity, the first gear can be driven to rotate by rotating the rotating rod, so that the threaded rod is driven to rotate under the engagement of the first gear and the second gear; the threaded rod and the thread of the adjustment plate can drive the adjustment plate to move under the cooperation to adjust the sound insulation effect of the wall.

[0015] Optionally, the adjustment assembly includes an adjustment rod, a pressing rod and a first spring, the adjustment rod is rotatably mounted on the inner wall of the adjustment cavity through a rotating shaft; the two ends of the adjustment rod are respectively connected to the adjustment plate and the pressing rod; the wall is provided with a pressing groove connected to the adjustment cavity, and the pressing rod is movably mounted in the pressing groove; A movable groove is provided on the outer wall of the wall, and a pressing part is integrally formed on the pressing rod. The pressing part is located in the movable groove. The two ends of the first spring are respectively connected to the inner wall of the movable groove and the pressing part. The elastic force of the first spring drives the pressing part to move toward a side away from the movable groove. A fixing component is installed on the wall, and the fixing component is used to fix the pressing part in the movable groove.

[0016] By adopting the above technical solution, when people press the pressing part, the pressing part moves toward one side of the adjusting cavity; at this time, the adjusting rod connected to the pressing rod rotates toward one side of the adjusting plate. Since the adjusting rod is connected to the adjusting plate, the adjusting plate can be moved toward one side of the pressing rod during the rotation of the adjusting rod, thereby increasing the distance between the two opposite sides of the sound insulation cavity. At this time, the position of the pressing part is fixed by using a fixing component, which can stop the adjustment plate from moving in the cavity; thereby, the extension directions of the two adjacent sound insulation components are in the same direction, so that external noise can enter the room through the wall.

[0017] When it is necessary to increase the noise reduction effect of the wall, the fixation of the pressing part and the inner wall of the movable groove is cancelled by the fixing component. At this time, the elastic force of the first spring drives the pressing part to move toward the side away from the pressing groove, so that the adjusting rod can push the adjusting plate toward the side away from the pressing rod, so as to reduce the distance between the two opposite side walls of the sound insulation cavity and increase the resistance of noise entering the wall.

[0018] Optionally, the fixing assembly includes a clamping block and a second spring, the outer wall of the pressing portion is provided with a first clamping groove, and the clamping block is movably installed in the first clamping groove; the two ends of the second spring are respectively connected to the clamping block and the inner wall of the first clamping groove, and the elastic force of the second spring is used to drive the clamping block to move toward a side away from the first clamping groove; the inner wall of the movable groove is provided with a second clamping groove for the clamping block to be inserted into.

[0019] By adopting the above-mentioned technical solution, when the pressing part needs to be fixed in the movable groove, the first clamping groove and the second clamping groove of the pressing part are arranged opposite to each other. At this time, the elastic force of the second spring drives the clamping block to move toward one side of the second clamping groove and be inserted into the second clamping groove, thereby completing the fixation of the pressing part and the inner wall of the movable groove.

[0020] Optionally, the adjustment cavity is filled with sound-absorbing cotton.

[0021] By adopting the above technical solution, the sound insulation effect of the wall is increased by setting the sound-absorbing cotton; and by reducing the distance between the two side walls of the sound insulation cavity, the sound insulation effect of the sound insulation component is improved, and the sound-absorbing cotton is in a fluffy state in the adjustment cavity, further improving its sound insulation effect. By increasing the distance between the two side walls of the sound insulation cavity, the sound insulation effect of the sound insulation component is weakened, and the sound-absorbing cotton shrinks to reduce the irregular pore size inside the sound-absorbing cotton, further reducing the sound insulation effect of the wall.

[0022] Optionally, the adjustment plate is provided with a connecting hole, and two ends of the connecting hole are respectively connected to the adjustment cavity and the sound insulation cavity.

[0023] By adopting the above technical solution and providing a connecting hole, the pressures in the sound insulation cavity and the adjustment cavity can be made the same, so as to facilitate changing the position of the adjustment plate in the cavity.

[0024] In a second aspect, the present application provides a construction method for a sound insulation and sound absorption wall structure, which specifically comprises the following steps: S1 builds angle steels, installs angle steels on the ground and beams of the wall to be installed, and sets two angle steels in parallel; S2 Base cleaning: clean the ground where the wall needs to be installed; S3 installs the wall, and installs all the walls in sequence between the ground and the beams and columns, with two angle steels abutting each other at both ends of the wall; S4 Caulking treatment: Caulking the wall and the ground / beams and columns, and removing the angle steel; S5 plate seam treatment, sealing treatment is performed between two adjacent walls.

After the wall is installed, the gaps between the wall and the ground and beams are caulked, and the gaps between two adjacent walls are filled to reduce the possibility of cracking and leakage and improve the installation quality.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By slidingly installing the adjustment plate in the cavity, it is convenient to adjust the sound insulation effect of the wall; when the distance between the two sides of the sound insulation cavity is reduced, the middle part of the sound insulation component is bent, reducing the noise from directly entering the room through the gap between the two adjacent sound insulation components, that is, increasing the barrier of noise entering the room through the wall, which plays a role in improving the sound insulation effect of the wall; when the distance between the two sides of the sound insulation cavity is increased, the extension directions of the two adjacent sound insulation components are in the same direction, which can make the external noise directly enter the room through the gap between the two adjacent sound insulation components, that is, it has the effect of weakening the sound insulation of the wall, so as to facilitate the transmission of external noise into the room; 2.

The two sound insulation cottons 33 are respectively pasted on the surfaces of the first plate 31 and the second plate 32.

[0034] Reference Figure 1 and Figure 2 , when the extension directions of the first plate 31 and the second plate 32 are in the same direction, they are in the first state, and when the extension directions of the first plate 31 and the second plate 32 are staggered, they are in the second state; when the first plate 31 and the second plate 32 are in the first state, the adjustment plate 4 is moved toward one side of the first plate 31, and the hinges at which the first plate 31 and the second plate 32 are connected to the inner wall of the sound insulation cavity 14 are rotated, and then the connection between the first plate 31 and the second plate 32 is rotated, so that the cross-section of the first plate 31 and the second plate 32 forms a V shape, that is, the first plate 31 and the second plate 32 are switched from the first state to the second state.

[0035] Reference Figure 1 The adjusting cavity 15 is filled with sound-absorbing cotton 5, which is made of polyurethane soft foam material, has good sound insulation and heat insulation properties, and has good resilience, and can increase the sound insulation effect of the wall 1; when the first plate 31 and the second plate 32 are in the first state, the sound-absorbing cotton 5 is in a compressed state; when the first plate 31 and the second plate 32 are in the second state, the sound-absorbing cotton 5 is in an expanded state.

[0036] Reference Figure 4 The adjustment assembly 2 includes a threaded rod 21, a rotating rod 22, a first gear 23 and a second gear 24, wherein one of the bottom plates 11 is provided with a sliding cavity 16, and the sliding cavity 16 is communicated with the cavity 13; a sliding portion 45 is integrally formed at one end of the adjustment plate 4, and the sliding portion 45 is slidably installed in the sliding cavity 16; the two ends of the threaded rod 21 are respectively rotatably installed on the opposite sides of the sliding cavity 16, the sliding portion 45 is provided with a threaded hole 42, the threaded rod 21 is penetrated by the threaded hole 42, and the outer wall of the threaded rod 21 matches the threaded hole 42.

[0041] Embodiment 2: The embodiment of the present application discloses a sound insulation and sound absorption wall 1 structure.

[0042] Reference Figure 6 and Figure 7 , the difference between the embodiment 2 of the present application and the embodiment 1 is that: the adjustment assembly 2 includes an adjustment rod 25, a pressing rod 26, a first spring 27 and a fixing assembly 28, the adjustment rod 25 is rotatably installed in the sliding cavity 16 through a rotating shaft 251, and the rotating shaft 251 separates the adjustment rod 25 into a first section 252 and a second section 253, and the length of the first section 252 is greater than the length of the second section 253; the adjustment plate 4 is provided with a sliding groove 43, and a slider 44 is slidably installed in the sliding groove 43, and the first section 252 is rotatably connected to the slider 44; refer to Figure 8 and Fig. 9 The second section 253 is provided with an avoidance groove 254 , in which an avoidance block 255 is slidably installed, and one end of the pressing rod 26 is rotatably connected to the avoidance block 255 .
