Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a sound-insulating and sound-absorbing wall structure and its construction method. Background Technology

[0002] With the rapid development of society and economy and the continuous improvement of people's material living standards, noise pollution has received increasing attention. According to relevant medical research, many hidden chronic diseases are related to noise and are often overlooked.

[0003] Existing walls are typically of a fixed thickness. In urban areas, sound insulation layers can be added to walls to improve sound insulation, but this effect cannot be enhanced when noise levels are high. However, in outdoor settings, where the wall thickness is fixed, the ambient noise levels vary between day and night. For example, near water, people may want to hear the sound of flowing water during the day, but at night they need to reduce noise for rest. Since the sound insulation of the wall is fixed and cannot be adjusted, the comfort of use is reduced. Summary of the Invention

[0004] To facilitate the adjustment of the sound insulation effect of the wall, this application provides a sound insulation and sound absorption wall structure and its construction method.

[0005] The first method, the sound insulation and sound absorption wall structure provided in this application, adopts the following technical solution:

[0006] A sound-insulating and sound-absorbing wall structure includes a wall, an adjustment component, and multiple sound-insulating components. A cavity is formed in the middle of the wall, and an adjustment plate is slidably installed within the cavity. The adjustment plate divides the cavity into an adjustment chamber and a sound-insulating chamber. All sound-insulating components are spaced apart along the height of the cavity, and both ends of each component are hinged to opposite sides of the cavity. The adjustment component is used to adjust the position of the adjustment plate within the cavity.

[0007] By adopting the above technical solution, at night, the position of the adjustment plate in the cavity can be changed by using the adjustment component, which can reduce the distance between the two sides of the sound insulation cavity. At this time, the two ends of the sound insulation component rotate on the two side walls of the sound insulation cavity respectively, and the middle of the sound insulation component bends. When external noise passes through the wall, it reduces the situation where noise directly enters the room through the gap between two adjacent sound insulation components, that is, it increases the obstruction of noise entering the room through the wall, thereby improving the sound insulation effect of the wall.

[0008] During the day, adjusting the position of the adjustment plate within the cavity using the adjustment components increases the distance between the two sides of the soundproofing cavity. At this time, the extension directions of two adjacent soundproofing components are in the same direction, allowing external noise to directly enter the room through the gap between the two adjacent soundproofing components. This weakens the wall's sound insulation, facilitating the transmission of external noise into the room. Adjusting the position of the adjustment plate within the cavity through the adjustment components allows for easy adjustment of the wall's soundproofing effect.

[0009] Optionally, the sound insulation component includes a first plate, a second plate, and two sound insulation cottons. The first plate and the second plate are respectively hinged to opposite sides of the sound insulation cavity, and the first plate and the second plate are rotatably connected on the side closest to each other. The two sound insulation cottons are respectively installed on the first plate and the second plate. When the distance between opposite sides of the sound insulation cavity decreases, the connection between the first plate and the second plate enters between the adjacent first plate and the second plate.

[0010] By adopting the above technical solution, during the process of reducing the distance between the two sides of the sound insulation cavity, the two ends of the first plate and the second plate rotate on the two sides of the sound insulation cavity respectively, so that the hinge of the first plate and the second plate rotates and enters between the adjacent first plate and the second plate.

[0011] When external noise enters the room through the wall, the noise is reduced from entering the room directly through the gap between two adjacent sound insulation components. That is, the noise entering the wall is absorbed by the sound insulation cotton, and the noise is absorbed by the sound insulation cotton through the gap between two adjacent sound insulation components, thereby adjusting the sound insulation effect of the wall.

[0012] Optionally, the first and second panels are connected by hinges, with all hinges located on the same side of all sound insulation components.

[0013] By adopting the above technical solution, all hinges are set on the same side of all sound insulation components, which can ensure that the hinges of all sound insulation components move in the same direction, reducing the possibility of collisions and damage between the hinges of two adjacent sound insulation components.

[0014] Optionally, the adjustment assembly includes a threaded rod, a rotating rod, a first gear, and a second gear. The two ends of the threaded rod are rotatably mounted on opposite sides of the cavity. The adjustment plate has a threaded hole, and the threaded rod is threadedly engaged with the threaded hole. The rotating rod is rotatably mounted on the wall. The first gear is rotatably mounted in the adjustment cavity and connected to the rotating rod. The second gear is mounted on the threaded rod, and the first gear and the second gear mesh with each other.

[0015] By adopting the above technical solution, when it is necessary to adjust the position of the sound insulation panel in the sound insulation cavity, rotating the rotating rod can drive the first gear to rotate, thereby driving the threaded rod to rotate under the meshing of the first gear and the second gear; the threaded rod and the adjusting plate can drive the adjusting plate to move, so as to adjust the sound insulation effect of the wall.

[0016] 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 via a rotating shaft. The two ends of the adjustment rod are respectively connected to the adjustment plate and the pressing rod. The wall has a pressing groove that communicates with the adjustment cavity, and the pressing rod is movably mounted in the pressing groove.

[0017] The outer wall of the wall has a movable groove, and the pressing rod is integrally formed with a pressing part, which 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 the side away from the movable groove. The wall is equipped with a fixing component, which is used to fix the pressing part in the movable groove.

[0018] By adopting the above technical solution, when people press the pressing part, the pressing part moves towards the side of the adjustment cavity; at this time, the adjustment rod connected to the pressing rod rotates towards the side of the adjustment plate. Since the adjustment rod is connected to the adjustment plate, the adjustment plate can be moved towards the side of the pressing rod during the rotation of the adjustment rod, thereby increasing the distance between the two sides of the sound insulation cavity. At this time, the position of the pressing part is fixed by the fixing component, which can stop the adjustment plate from moving in the cavity; thus, the extension direction of the two adjacent sound insulation components is the same, so that external noise can enter the room through the wall.

[0019] When it is necessary to increase the noise reduction effect of the wall, the fixing of the pressing part to the inner wall of the movable groove is removed by fixing the fixing component. At this time, the elastic force of the first spring drives the pressing part to move away from the pressing groove, so that the adjusting rod can push the adjusting plate away from the pressing rod, thereby reducing the distance between the two side walls of the sound insulation cavity and increasing the resistance of noise entering the wall.

[0020] Optionally, the fixing component includes a snap-fit ​​block and a second spring. The outer wall of the pressing part has a first snap-fit ​​groove, and the snap-fit ​​block is movably installed in the first snap-fit ​​groove. The two ends of the second spring are respectively connected to the snap-fit ​​block and the inner wall of the first snap-fit ​​groove. The elastic force of the second spring is used to drive the snap-fit ​​block to move toward the side away from the first snap-fit ​​groove. The inner wall of the movable groove has a second snap-fit ​​groove for the snap-fit ​​block to insert into.

[0021] By adopting the above technical solution, when it is necessary to fix the pressing part in the movable groove, the first locking groove and the second locking groove of the pressing part are set facing each other. At this time, the elastic force of the second spring drives the locking block to move toward one side of the second locking groove and insert it into the second locking groove, thereby completing the fixing of the pressing part to the inner wall of the movable groove.

[0022] Optionally, the adjustment cavity is filled with sound-absorbing cotton.

[0023] By adopting the above technical solution, the sound insulation effect of the wall is increased by setting sound-absorbing cotton; and by reducing the distance between the sound insulation cavity and the two side walls, the sound insulation effect of the sound insulation component is improved, while the sound-absorbing cotton is in a fluffy state inside the cavity, further improving its sound insulation effect. Increasing the distance between the sound insulation cavity and the two side walls weakens the sound insulation effect of the sound insulation component, while 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.

[0024] Optionally, the adjusting plate has a connecting hole, and the two ends of the connecting hole are respectively connected to the adjusting cavity and the sound insulation cavity.

[0025] By adopting the above technical solution and setting a connecting hole, the pressure in the sound insulation cavity and the adjustment cavity can be made the same, so as to change the position of the adjustment plate in the cavity.

[0026] Secondly, the construction method for a sound-insulating and sound-absorbing wall structure provided in this application specifically includes the following steps:

[0027] S1. Install angle steel on the ground and beams / columns of the wall to be installed, with two angle steels set in parallel.

[0028] S2 Base cleaning involves cleaning the floor where wall installation will be performed.

[0029] S3 installs the walls, placing all the walls sequentially between the ground and the beams and columns, with two angle steels abutting at each end of the wall;

[0030] S4 caulking treatment involves caulking the joints between the wall and the floor / beam / column, and removing the angle steel.

[0031] S5 panel joint treatment involves sealing the joints between two adjacent walls.

[0032] By adopting the above technical solution, angle steel is installed on the ground and beams and columns during construction, which can keep all walls parallel. After the walls are installed, the joints between the walls and the ground and beams and columns are filled, and the joints between two adjacent walls are also filled to reduce the possibility of cracking and leakage and improve the installation quality.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By sliding the adjustment plate into the cavity, the sound insulation effect of the wall can be adjusted. When the distance between the two sides of the sound insulation cavity decreases, the middle of the sound insulation component bends, reducing the direct entry of noise into the room through the gap between two adjacent sound insulation components. This increases the obstruction of noise entering the room through the wall, thus improving the sound insulation effect of the wall. When the distance between the two sides of the sound insulation cavity increases, the extension direction of the two adjacent sound insulation components is the same, allowing external noise to directly enter the room through the gap between the two adjacent sound insulation components. This weakens the sound insulation of the wall, making it easier for external noise to be transmitted into the room.

[0035] 2. By setting sound-absorbing cotton, the sound insulation effect of the sound insulation component is improved by reducing the distance between the two side walls of the sound insulation cavity. At the same time, the sound-absorbing cotton is in a fluffy state in the adjustment cavity, which further improves its sound insulation effect. Conversely, 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. At the same time, the sound-absorbing cotton shrinks to reduce the irregular pore size inside the sound-absorbing cotton, which further reduces the sound insulation effect of the wall.

[0047] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0048] Example 1:

[0049] This application discloses a sound insulation and sound absorption wall structure 1.

[0050] Reference Figure 1 A sound insulation and sound absorption wall structure 1 includes a wall 1, an adjustment component 2 and multiple sound insulation components 3. The wall 1 is made of concrete. The wall 1 includes two base plates 11 and four cover plates 12. The two ends of the four cover plates 12 are respectively connected to the edges of the two base plates 11 so that all the cover plates 12 and the base plates 11 enclose a cavity 13.

[0051] Reference Figure 1 and Figure 2 The cavity 13 is divided into a sound insulation cavity 14 and an adjustment cavity 15 by an adjustment plate 4. The adjustment plate 4 is slidably installed inside the cavity 13. All sound insulation components 3 are installed in the sound insulation cavity 14 and are spaced apart along the height direction of the sound insulation cavity 14. The sound insulation components 3 are used to make the wall 1 have a sound insulation effect. The adjustment components 2 are used to change the position of the adjustment plate 4 in the cavity 13. The adjustment plate 4 has a connecting hole 41, and the two ends of the connecting hole 41 are connected to the sound insulation cavity 14 and the adjustment cavity 15 respectively. The setting of the connecting hole 41 can keep the pressure of the sound insulation cavity 14 and the adjustment cavity 15 the same, so as to maintain the smooth sliding of the adjustment plate 4 in the cavity 13.

[0052] Reference Figure 3A sound transmission channel 35 is formed between two adjacent sound insulation components 3. The sound insulation component 3 includes a first plate 31, a second plate 32, and two sound insulation cottons 33. One end of the first plate 31 and the second plate 32 are respectively hinged to the opposite side walls of the sound insulation cavity 14. The sides of the first plate 31 and the second plate 32 that are close to each other are hinged together by hinges 34, and all hinges 34 are located on the same side of all the first plates 31. The sound insulation cottons 33 are made of a variety of porous sound insulation materials and have good sound insulation effect. The two sound insulation cottons 33 are respectively pasted on the surface of the first plate 31 and the second plate 32.

[0053] 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; when the extension directions of the first plate 31 and the second plate 32 are intersecting, they are in the second state. When the first plate 31 and the second plate 32 are in the first state, the adjusting plate 4 is moved toward the side of the first plate 31, and the hinge connecting the first plate 31 and the second plate 32 to the inner wall of the sound insulation cavity 14 rotates, thereby causing the connection between the first plate 31 and the second plate 32 to rotate, 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.

[0054] Reference Figure 1 The adjustment cavity 15 is filled with sound-absorbing cotton 5, which is made of polyurethane soft foam material. It has good sound insulation and heat insulation performance and good resilience, which 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.

[0055] Reference Figure 4 The adjusting assembly 2 includes a threaded rod 21, a rotating rod 22, a first gear 23, and a second gear 24. One of the base plates 11 has a sliding cavity 16, which is connected to the cavity 13. One end of the adjusting plate 4 is integrally formed with a sliding part 45, which is slidably installed in the sliding cavity 16. The two ends of the threaded rod 21 are rotatably installed on opposite sides of the sliding cavity 16. The sliding part 45 has a threaded hole 42, through which the threaded rod 21 passes, and the outer wall of the threaded rod 21 is engaged with the threaded hole 42.

[0056] Reference Figure 5 The second gear 24 is fixed to the threaded rod 21. The outer wall of the base plate 11 is provided with a rotating groove 19, which is connected to the sliding cavity 16. The rotating rod 22 is rotatably installed in the rotating groove 19. The first gear 23 is fixed to one end of the rotating rod 22 near the sliding cavity 16. The first gear 23 and the second gear 24 mesh with each other.

[0057] When people rotate the rotating rod 22 from the outside, the first gear 23 can be rotated, which in turn causes the threaded rod 21 to rotate under the meshing of the first gear 23 and the second gear 24. Since the threaded rod 21 is threadedly engaged with the threaded hole 42 and the adjusting plate 4 is slidably connected to the sliding cavity 16, the adjusting rod 25 can slide within the sliding cavity 16 to change the distance between the two side walls of the sound insulation cavity 14.

[0058] The implementation principle of Embodiment 1 of this application is as follows:

[0059] During the day, the first panel 31 and the second panel 32 are switched to the first state, at which point external sound directly enters the room through the sound transmission channel 35. When the first panel 31 and the second panel 32 are in the first state, the sound-absorbing cotton 5 is compressed, reducing the irregular pore size inside the sound-absorbing cotton 5 and further reducing the sound insulation effect of the wall 1. When it is necessary to increase the sound insulation effect of the wall 1, the rotating rod 22 is rotated, causing the cross-section of the sound transmission channel 35 to form a V-shape, thus switching the first panel 31 and the second panel 32 to the second state. During the process of external noise entering the room through the wall 1, the noise is blocked and absorbed by the sound-absorbing cotton 33 on the side wall of the sound transmission channel 35, and the sound-absorbing cotton 5 expands, increasing the irregular pore size inside, further improving the sound insulation effect of the wall 1.

[0060] By adjusting the position of the adjustment plate 4, the first and second states of the first plate 31 and the second plate 32, as well as the compression and expansion states of the sound-absorbing cotton 5, can be switched, thereby adjusting the sound insulation effect of the wall 1, improving the practicality of the wall 1, and increasing the comfort of people's living space.

[0061] Example 2:

[0062] This application discloses a sound insulation and sound absorption wall structure 1.

[0063] Reference Figure 6 and Figure 7 The difference between Embodiment 2 and Embodiment 1 is that: the adjusting assembly 2 includes an adjusting rod 25, a pressing rod 26, a first spring 27, and a fixing assembly 28. The adjusting rod 25 is rotatably mounted in the sliding cavity 16 via a rotating shaft 251. The rotating shaft 251 divides the adjusting rod 25 into a first segment 252 and a second segment 253, the length of the first segment 252 being greater than the length of the second segment 253. The adjusting plate 4 has a sliding groove 43, in which a slider 44 is slidably mounted. The first segment 252 is rotatably connected to the slider 44. (Refer to...) Figure 8 and Figure 9 The second section 253 has a relief groove 254, and a relief block 255 is slidably installed in the relief groove 254. One end of the pressing rod 26 is rotatably connected to the relief block 255.

[0064] Reference Figure 8 The sliding cavity 16 has a pressing groove 17 on its inner wall, and the pressing rod 26 is movably installed in the pressing groove 17. The bottom plate 11 has a movable groove 18 on its outer wall that communicates with the pressing groove 17. The pressing rod 26 has a pressing part 261 integrally formed at the end away from the avoidance block 255, and the pressing part 261 is movably installed in the movable groove 18. The first spring 27 is sleeved on the outer wall of the pressing rod 26, and the two ends of the first spring 27 are fixed to the inner wall of the movable groove 18 and the inner wall of the pressing part 261, respectively. The elastic force of the first spring 27 drives the pressing part 261 to move toward the end away from the first spring 27, and the pressing part 261 is normally located in the movable groove 18.

[0065] Reference Figure 10 The fixing component 28 includes a snap-fit ​​block 281 and a second spring 282. The outer wall of the pressing part 261 is provided with a first snap-fit ​​groove 283, and the snap-fit ​​block 281 is movably installed in the first snap-fit ​​groove 283. The two ends of the second spring 282 are respectively connected to the inner wall of the first snap-fit ​​groove 283 and the snap-fit ​​block 281. The elastic force of the second spring 282 is used to drive the snap-fit ​​block 281 to move toward the side away from the second snap-fit ​​groove 284. The inner wall of the movable groove 18 is provided with a second snap-fit ​​groove 284 for the snap-fit ​​block 281 to be inserted into. During the process of the pressing part 261 moving toward the side of the movable groove 18, the first snap-fit ​​groove 283 and the second snap-fit ​​groove 284 are positioned opposite each other, and the snap-fit ​​block 281 is inserted into the second snap-fit ​​groove 284.

[0066] The pressing part 261 has an unlocking groove 285 at the end away from the pressing rod 26, which is connected to the first locking groove 283. An unlocking rod 286 is slidably installed in the unlocking groove 285, with one end of the unlocking rod 286 passing through the unlocking groove 285 and exposed to the outside, and the other end of the unlocking rod 286 being fixed to the locking block 281. By moving the unlocking rod 286 in the unlocking groove 285, the locking block 281 connected to the unlocking rod 286 can be disengaged from the second locking groove 284. At this time, the pressing part 261 moves away from the movable groove 18 under the elastic force of the second spring 282, thereby switching the first plate 31 and the second plate 32 to the second state.

[0067] The implementation principle of Embodiment 2 of this application is as follows:

[0068] When people press the pressing part 261, the pressing part 261 moves toward the side of the adjustment cavity 15; at this time, the adjustment rod 25 connected to the pressing rod 26 rotates toward the side of the adjustment plate 4. Since the adjustment rod 25 is connected to the adjustment plate 4, the adjustment rod 25 can move the adjustment plate 4 toward the side of the pressing rod 26 during rotation, thereby increasing the distance between the two sides of the sound insulation cavity 14. When the first locking groove 283 and the second locking groove 284 are aligned, the locking block 281 is inserted into the second locking groove 284, which can stop the adjustment plate 4 from moving in the cavity 13. At this time, the first plate 31 and the second plate 32 are in the first state, which makes it convenient for people to hear the outdoor sound indoors.

[0069] When it is necessary to increase the noise reduction effect of the wall 1, the locking block 281 is disengaged from the second locking groove 284 by sliding the unlocking rod 286 in the unlocking groove 285. At this time, the elastic force of the first spring 27 drives the pressing part 261 to move away from the pressing groove 17, so that the adjusting rod 25 can push the adjusting plate 4 away from the pressing rod 26, thereby reducing the distance between the sound insulation cavity 14 and the two side walls and increasing the resistance of noise entering the wall 1.

[0070] This application also discloses a construction method for a sound-insulating and sound-absorbing wall structure 1, which specifically includes the following steps:

[0071] S1 constructs angle steel. An installation space is set in the beams and columns of the wall to be installed. Positioning lines for the angle steel are marked on the installation space and the ground. The angle steel is fixed to the ground and beams and columns with bolts. The two angle steels are set in parallel.

[0072] S2 base cleaning involves cleaning the dust from the ground and the space between beams and columns where installation is to be carried out;

[0073] S3 installs wall 1. All wall 1s are prefabricated in the factory. All wall 1s are installed sequentially between the ground and the space to be installed between the beams and columns. One side of wall 1 abuts against two angle steel sidewalls, and two adjacent wall 1s abut against each other.

[0074] S4 caulking treatment: fill the space between wall 1 and beam / column with concrete, fill the space between wall 1 and the ground with cement mortar, and remove the angle steel after the concrete and cement mortar have fixed.

[0075] For S5 panel joint treatment, apply sealant between two adjacent wall sections 1, smooth and finish the sealant surface with a brush, remove excess sealant, and form a U-shaped groove; after the sealant has cured, fill the U-shaped groove tightly with thermal insulation mortar mixed with crack-resistant agent.

[0076] S6 Wall 1 treatment: Inspect the surface of wall 1 for dust, oil stains, cement mortar drips, etc., and apply a moisture-proof primer to the surface of wall 1.

[0077] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
