Description

Technical Field

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

[0002] With the improvement of living standards, in order to provide people with a comfortable living environment, soundproof walls are usually added to buildings to reduce the penetration and transmission of noise and ensure the quality of life.

[0003] Publication No. CN218437755U discloses an assembled soundproof wall, whose technical solution includes a wall body 1 and a wall body 2, wherein the inner surfaces of the wall body 1 and the wall body 2 are provided with reinforcement units, and the outer surfaces of the wall body 1 and the wall body 2 are respectively fixedly installed with soundproof units.

[0004] The above technical solution, by adopting the setting of the sound insulation unit, can reduce the sound propagation efficiency and improve the sound insulation effect between wall one and wall two. At the same time, by strengthening the unit, it is easy to install wall one and wall two, thereby improving work efficiency. However, in the above technical solution, wall one and wall two are installed to each other by splicing, so there will be a gap between wall one and wall two. When sound is emitted, the sound will be transmitted to the other side of wall one and wall two through the gap, thereby affecting the sound insulation effect of the wall.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a soundproof wall, which solves the problem that when sound is emitted, the sound will be transmitted to the other side of wall one and wall two through the gap between wall one and wall two, thus affecting the sound insulation effect of the wall.

[0007] The above technical purpose of the utility model is achieved through the following technical scheme: a sound insulation wall, including a plurality of walls connected to each other, two installation frames are fixedly connected on both sides of the plurality of walls, two limiting grooves are respectively opened on both sides of the two installation frames, the two limiting grooves are slidably connected, the two limiting grooves are connected by a fixing component, and the inner side walls of the two installation frames are provided with a noise reduction component for reducing the sound transmitted to the installation frames.

[0008] By adopting the above technical solution, when installing the wall, the wall panel is pushed to drive the limit grooves on the two installation frames to slide against each other. After the two limit grooves slide to the designated area, the two installation frames are fixed to each other through the fixing components, thereby completing the effect of installing the two wall panels. When sound occurs, the sound will propagate toward the side wall of the installation frame. When the sound enters the connecting frame, the noise reduction component in the connecting frame can refract the transmission of sound waves in the sound, thereby achieving the effect of reducing the sound and improving the sound insulation effect of the wall.

[0009] The utility model is further configured as follows: the noise reduction component includes a plurality of sound-absorbing panels fixedly connected to the inner side walls of the two installation frames, the cross sections of the plurality of sound-absorbing panels are arranged in a wave shape, and there is a spacing between two adjacent sound-absorbing panels and they are arranged parallel to each other.

[0010] By adopting the above technical solution, when sound enters the installation frame, the sound will begin to propagate in the direction of the sound-absorbing board. When the sound waves in the sound contact the sound-absorbing board, since the cross-section of the sound-absorbing board is wavy, the sound will be affected by the inclined surface of the side wall of the sound-absorbing board and rebound, and begin to propagate in the direction of the other sound-absorbing board. When contacting the other sound-absorbing board, the sound wave is rebounded again by the other sound-absorbing board, thereby achieving the effect of extending the sound wave propagation path. The longer the sound wave propagation path, the lower the decibel, thereby achieving the effect of improving the noise reduction of the wall.

[0011] The utility model is further configured as follows: a cross section of one side of the two installation frames close to the wall is consistent with a cross section of the sound-absorbing plate.

[0012] By adopting the above technical solution, the propagation path of the sound between the installation frame and the sound-absorbing panel can be increased, thereby improving the noise reduction effect of the wall.

[0013] The utility model is further configured as follows: a plurality of sound absorbing holes are provided on the side walls of the plurality of sound absorbing plates.

[0014] By adopting the above technical solution, part of the sound transmitted to the sound-absorbing board can be absorbed, thereby further improving the sound-absorbing effect of the sound-absorbing board.

[0015] The utility model is further configured as follows: the fixing assembly comprises a plurality of bolts, and the two side walls of the installation frames are provided with a plurality of threaded holes for threaded connection of the bolts.

[0016] By adopting the above technical solution, when the wall needs to be installed, the two installation frames are driven to start moving. When the threaded holes on the two installation frames overlap with each other, the bolts are inserted into the through holes and the bolts are driven to start rotating. The two installation frames are fixed to each other by the bolts, thereby achieving the effect of wall installation.

[0017] The utility model is further configured as follows: a placement groove is provided on one of the side walls of the limiting groove, a wedge block is slidably connected in the placement groove, the wedge block and the placement groove are connected by a spring, and a groove is provided on the other side wall of the limiting groove for the wedge block to be inserted, and when the wedge block is inserted into the groove, the spring is in a natural state.

[0018] By adopting the above technical solution, when the installation frame is driven to move, the installation frame will contact the side wall of the wedge block, and the wedge block will be affected by the installation frame and begin to move downward along the placement groove, while driving the spring to begin to deform and compress. When the installation frame moves to the point where the groove and the placement groove overlap, the spring loses its restriction and begins to deform and recover, driving the wedge block into the groove while making an impact sound. At this time, the staff can judge whether the installation frame has moved to the designated area through this impact layer, which is convenient for the subsequent fixation of the installation frame. At the same time, through the setting of the wedge plate, the two installation frames can also be pre-fixed.

[0019] The utility model is further configured as follows: a sound insulation layer is provided between the two limit grooves.

[0020] By adopting the above technical solution, the sound insulation effect between the two installation frames can be improved.

[0021] In summary, the utility model has the following beneficial effects: when installing the wall, the wall panel is pushed to drive the limit grooves on the two installation frames to slide against each other. After the two limit grooves slide to the designated area, the two installation frames are fixed to each other through the fixing components, thereby completing the installation of the two wall panels. When sound occurs, the sound will propagate toward the side wall of the installation frame. When the sound enters the connecting frame, the noise reduction component in the connecting frame can refract the transmission of sound waves in the sound, thereby achieving the effect of reducing the sound and improving the sound insulation effect of the wall.

[0029] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] A soundproof wall, such as Figure 1-Figure 4 As shown, it includes several walls 1 connected to each other, two installation frames 2 are fixedly connected on both sides of the several walls 1, two limit grooves 3 are respectively opened on both sides of the two installation frames 2, the two limit grooves 3 are slidably connected, and the two limit grooves 3 are connected by a fixing component. The inner walls of the two installation frames 2 are provided with a noise reduction component for reducing the sound transmitted to the installation frame 2. When installing the wall 1, the wall panel is pushed to drive the limit grooves 3 on the two installation frames 2 to slide against each other. After the two limit grooves 3 slide to the specified area, the two installation frames 2 are fixed to each other by the fixing component, thereby completing the effect of installing the two wall panels. When sound occurs, the sound will propagate toward the side wall of the installation frame 2. When the sound enters the connecting frame, the noise reduction component in the connecting frame can refract the transmission of sound waves in the sound, thereby achieving the effect of reducing the sound and improving the sound insulation effect of the wall 1.

[0031] like Figure 1-Figure 4As shown, the noise reduction component includes a plurality of sound-reducing plates 4 fixedly connected to the inner side walls of the two mounting frames 2. The cross sections of the plurality of sound-reducing plates 4 are arranged in a wavy shape. There is a spacing between two adjacent sound-reducing plates 4 and they are arranged in parallel with each other. When the sound enters the mounting frame 2, the sound will begin to propagate in the direction of the sound-reducing plates 4. When the sound waves in the sound contact with the sound-reducing plates 4, since the cross sections of the sound-reducing plates 4 are wavy, the sound will be affected by the inclined surfaces of the side walls of the sound-reducing plates 4 and rebound, and begin to propagate in the direction of the other sound-reducing plates 4. When contacting with the other sound-reducing plates 4, the sound waves will be reflected by the inclined surfaces of the side walls of the sound-reducing plates 4. The sound waves are rebounded again by another sound-absorbing plate 4, so as to achieve the effect of extending the sound wave propagation path. The longer the sound wave propagation path, the lower the decibel, so as to achieve the effect of improving the noise reduction effect of the wall 1. The cross-section of the side of the two installation frames 2 close to the wall 1 is consistent with the cross-section of the sound-absorbing plate 4, which can increase the propagation path of the sound propagated between the installation frame 2 and the sound-absorbing plate, and improve the noise reduction effect of the wall 1. The side walls of the sound-absorbing plates 4 are provided with a plurality of sound-absorbing holes 5, which can absorb part of the sound propagated to the sound-absorbing plates 4, and further improve the sound-absorbing effect of the sound-absorbing plates 4.

[0032] like Figure 1-Figure 4 As shown, the fixing assembly includes a plurality of bolts 6, and the side walls of the two installation frames 2 are provided with a plurality of threaded holes 7 for the bolts 6 to be threadedly connected. When the wall 1 needs to be installed, the two installation frames 2 are driven to start moving. When the threaded holes 7 on the two installation frames 2 overlap each other, the bolts 6 are inserted into the through holes, and the bolts 6 are driven to start rotating. The two installation frames 2 are fixed to each other by the bolts 6, so as to achieve the effect of installing the wall 1.

[0033] like Figure 1-Figure 4 As shown, one of the side walls of the limit groove 3 is provided with a placement groove 8, and a wedge block 9 is slidably connected in the placement groove 8. The wedge block 9 and the placement groove 8 are connected by a spring 10. The side wall of the other limit groove 3 is provided with a groove 11 for the wedge block 9 to be inserted. When the wedge block 9 is inserted into the groove 11, the spring 10 is in a natural state. When the installation frame 2 is driven to move, the installation frame 2 will contact the side wall of the wedge block 9. At the same time, the wedge block 9 will be affected by the installation frame 2 and begin to move downward along the placement groove 8, while driving the spring 10 to begin to deform and compress. When the installation frame 2 moves to the point where the groove 11 coincides with the placement groove 8, the spring 10 loses its restriction and begins to deform and recover, and drives the wedge block 9 to enter the groove 11, and at the same time makes a knocking sound. At this time, the staff can judge whether the installation frame 2 has moved to the specified area through this knocking layer, which is convenient for the subsequent fixation of the installation frame 2. At the same time, through the setting of the wedge plate, the two installation frames 2 can also be pre-fixed.

[0034] like Figure 1-Figure 4 As shown, a sound insulation layer 12 is provided between the two limiting grooves 3 , which can improve the sound insulation effect between the two installation frames 2 .

[0035] The utility model is used normally as follows: when installing the wall 1, the wall panel is pushed to drive the limit grooves 3 on the two installation frames 2 to slide against each other. When the threaded holes 7 on the two installation frames 2 overlap with each other, the bolts 6 are inserted into the through holes, and the bolts 6 are driven to start rotating. The two installation frames 2 are fixed to each other by the bolts 6, thereby completing the effect of installing the two wall panels. When sound occurs, the sound will propagate toward the side wall of the installation frame 2. When the sound enters the connecting frame, the sound will begin to propagate toward the direction of the silencer plate 4. When the sound waves in the sound contact with the silencer plate 4, since the cross-section of the silencer plate 4 is wavy, the sound will be affected by the inclined surface of the side wall of the silencer plate 4 and rebound, and begin to propagate toward the other silencer plate 4. When contacting with the other silencer plate 4, the sound waves are rebounded again by the other silencer plate 4, thereby achieving the effect of extending the sound wave propagation path. The longer the sound wave propagation path, the lower the decibel, thereby achieving the effect of reducing the sound and improving the sound insulation effect of the wall 1.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
