Description

Technical Field

[0001] The present application relates to the field of urban sound insulation technology, and in particular to a high-rise building with a green sound environment. Background Art

[0002] With the acceleration of urbanization and people's better quality of life, vehicles have become the most commonly used means of transportation for people. The surge in the number of vehicles has brought convenience to people, but it has also brought new challenges to the daily lives of urban residents. Noise pollution has become more and more troublesome to people's lives. There are generally three ways to reduce noise: noise reduction at the sound source, noise reduction on the propagation path, and noise reduction at the receiving point. For road vehicles, noise reduction is generally done on the propagation path.

[0003] The patent with authorization announcement number CN207537907U discloses a multifunctional road sound barrier, comprising two columns, between which an upper louver-type sound insulation screen, a safety glass sound insulation screen, a middle louver-type sound insulation screen and a lower louver-type sound insulation screen are arranged in sequence from top to bottom, the lower end of the middle louver-type sound insulation screen is bent downward toward a first side, the upper end of the lower louver-type sound insulation screen is bent upward toward a second side opposite to the first side, and a gap is formed between the lower end of the middle louver-type sound insulation screen and the upper end of the lower louver-type sound insulation screen.

[0004] Regarding the above-mentioned related technologies, there are the following defects: the road sound barrier has a limited height, which can effectively isolate noise for low-level users in the community, but for high-rise buildings, the noise still passes through the barrier and brings noise pollution to indoor users. Summary of the invention

[0005] In order to provide a green sound environment with good sound insulation for high-rise residents, the present application provides a high-rise building with a green sound environment.

[0006] The application provides a high-rise building with a green sound environment using the following technical solutions:

[0007] A high-rise building with a green sound environment comprises a wall, wherein an exterior wall panel is arranged on the wall surface of the wall close to the outdoors, the exterior wall panel is arranged obliquely, the top edge of the exterior wall panel is far from the wall, a sound insulation layer is filled between the exterior wall panel and the wall, the sound insulation layer is fixedly connected to the wall and the exterior wall panel, and the exterior wall panel is evenly spaced and arranged in multiple rows on the wall in the vertical direction.

[0008] By adopting the above technical solution, when the noise passes through the sound barrier on the street and the sound waves are transmitted to the upper floors, the sound waves first contact the exterior wall panels outside the wall. The exterior wall panels arranged in a scale-like manner in an inclined state increase the distance between the contact point of the sound waves on the exterior wall panels and the indoor space, and the strong sound insulation properties of the thicker sound insulation layer between the exterior wall panels and the wall can better isolate outdoor noise, provide a better green sound environment for the indoor space, and enable users to work and rest indoors in a quiet environment.

[0009] Optionally, a rain shelter is fixedly connected to the board surface of the exterior wall panel away from the wall, and the straight-line distance between the edge of the rain shelter away from the exterior wall panel and the wall is greater than the straight-line distance between the upper edge of the exterior wall panel and the wall.

[0010] By adopting the above technical solution, the rain shelter can cover the top of the sound insulation layer, which can effectively prevent the sound insulation layer from accelerating aging in the external environment of sun and rain, and improve the service life of the sound insulation layer.

[0011] Optionally, the lower portion of the exterior wall panel is hinged to the wall, and the hinge axis of the exterior wall panel is horizontal.

[0012] By adopting the above technical solution, the exterior wall panel is hinged to the wall. When the exterior wall panel receives sound waves, the sound waves will drive the exterior wall panel to vibrate. The exterior wall panel rotates around the hinge axis, thereby consuming the sound wave energy accumulated on the exterior wall panel, thereby further reducing outdoor noise.

[0013] Optionally, a baffle plate parallel to the outer wall panel is fixedly connected to the edge of the rain shelter eave away from the outer wall panel, and the baffle plate is located below the rain shelter eave.

[0014] By adopting the above technical solution, the baffle abuts against the side of the exterior wall panel away from the wall, which can effectively prevent the exterior wall panel from rotating and falling after the bonding force between the sound insulation layer and the exterior wall panel weakens, thereby further improving the installation stability of the exterior wall panel.

[0015] Optionally, a buffer layer is provided between the baffle and the outer wall panel of the lower layer.

[0016] By adopting the above technical solution, when the wind or sound drives the exterior wall panel to vibrate, a buffer layer is added to the diameter of the movable end of the baffle and the upper exterior wall panel, which can effectively absorb the impact and noise of the collision between the exterior wall panel and the baffle, and further maintain the green sound environment effect.

[0017] Optionally, the rain shelter is detachably connected to the exterior wall panel, and the exterior wall panel is detachably connected to the wall.

[0018] By adopting the above technical solution, when the sound insulation effect of the sound insulation layer is weakened and it needs to be disassembled for maintenance, the rain shield can be removed from the outer baffle plate, and the sound insulation layer can be removed from between the two outer wall panels, which is convenient to use.

[0019] Optionally, plug-in grooves are vertically opened on the vertical side walls on both sides of the exterior wall panels and the rain shelters, and waterproof strips adapted to the plug-in grooves are provided between two adjacent exterior wall panels and between two adjacent rain shelters at the same height, and the waterproof strips are snapped into the plug-in grooves.

[0020] By adopting the above technical solution, a waterproof strip is embedded between two exterior wall panels on the same horizontal plane, which can effectively prevent rainwater from penetrating into the sound insulation layer when passing over the eaves and the exterior wall panels, keep the wall and the exterior wall panels dry, and extend the service life of the sound insulation layer.

[0021] Optionally, a support rod is fixedly connected inside the waterproof strip, the axis of the support rod is horizontal, and a plurality of the support rods are arranged at intervals along the length direction of the waterproof strip.

[0022] By adopting the above technical solution, the support rods can enhance the structural stability of the waterproof strip, effectively prevent the sound insulation layer from being exposed due to misalignment between adjacent panels, further enhance the waterproof effect between exterior wall panels and between rain shelters, and the support rods can connect exterior wall panels or rain shelters at the same height, effectively prevent the sound insulation effect from being weakened due to misalignment between exterior wall panels or rain shelters, and further maintain the sound insulation effect.

[0023] Optionally, the sound insulation layer is made of PU foam.

[0024] By adopting the above technical solution, the PU foam is light in texture, which effectively reduces the burden on the building. The porous structure has good sound absorption effect and good elasticity, which facilitates the rotation of the exterior wall panels on the wall.

[0025] Optionally, the exterior wall panel is a double-layer hollow structure.

[0026] By adopting the above technical solution, the double-layer hollow structure of the exterior wall panel can filter noise well and further enhance the sound insulation effect of the exterior wall panel.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The scaly-shaped exterior wall panels in an inclined state increase the distance between the sound wave contact point on the exterior wall panels and the indoor space, and the strong sound insulation characteristics of the thicker sound insulation layer between the exterior wall panels and the wall can better isolate outdoor noise, provide a better green sound environment for the indoor space, and enable users to work and rest indoors in a quiet environment;

[0029] 2. The rain shelter can block the top of the sound insulation layer, which can effectively prevent the sound insulation layer from accelerating aging in the sun and rain environment, and extend the service life of the sound insulation layer;

[0030] 3. The exterior wall panel is hinged to the wall. When the exterior wall panel receives sound waves, the sound waves will drive the exterior wall panel to vibrate. The exterior wall panel rotates around the hinge axis, consuming the sound wave energy accumulated on the exterior wall panel, further reducing outdoor noise. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The present application embodiment discloses a high-rise building with a green sound environment. Figure 1 The high-rise building includes a vertical wall 1 on the outside of the building, a multi-layer exterior wall panel 2 rotatably installed on the wall 1, and a sound insulation layer 3 between the exterior wall panel 2 and the wall 1.

[0038] Reference Figure 2 , 3 The material of the exterior wall panel 2 is a PVC board with a hollow double-layer structure. The surface of the exterior wall panel 2 close to the outside can be matte treated, and the surface of the exterior wall panel 2 close to the inside can be pressed with a pattern to disperse the transmission direction of the sound wave after passing through the exterior wall panel 2. A connecting plate is integrally fixed to the surface of the exterior wall panel 2 close to the inside, and a rotating shaft 81 is integrally formed on the connecting plate.

[0039] Reference Figure 2 , 3A mounting base 7 is bolted and fixed on the surface of the wall 1 near the outside. The mounting base 7 includes a mounting plate 72 connected to the wall 1 and two ear plates 71 perpendicular to the wall 1. A clamping groove 74 is downwardly opened on the top wall of the ear plate 71, and the bottom of the clamping groove 74 is an arc surface with a concave surface facing upward. A depression is opened on the vertical inner side wall of one side of the clamping groove 74, and a protrusion 73 matching the depression is protruded on the inner side wall on the other side directly opposite to it.

[0040] Reference Figure 2 , 3 , the connecting plate is close to one side edge of the exterior wall panel 2, and the mounting seats 7 are installed in pairs on the wall 1. When installing the exterior wall panel 2, the rotating shaft 81 is inserted into the groove from the clamping groove 74 on the mounting seat 7, so that the rotating shaft 81 fits with the arc surface at the bottom of the clamping groove 74. And when the exterior wall panel 2 is rotated to be parallel to the wall surface of the wall 1, the edge of the side of the exterior wall panel 2 that is farther from the rotating shaft 81 faces upward. The mounting seats 7 and the exterior wall panel 2 are used as a set, and multiple rows are evenly spaced in the vertical direction, which can be 8 rows or 9 rows. The distance between two adjacent rows of mounting seats 7 in the vertical direction should be less than the vertical height of the exterior wall panel 2 when it is parallel to the wall 1.

[0041] Reference Figure 2 , 3 A rain shield 4 is bolted and fixed on the surface of the outer wall panel 2 away from the wall body 1. The rain shield 4 is close to the lower edge of the outer wall panel 2 and parallel to the lower edge of the outer wall panel 2. A support plate is integrally formed on the edge of the rain shield 4 close to the outer wall panel 2, and the support plate is fixedly connected to the outer wall panel 2 by bolts. A waterproof rubber cushion layer 41 is also provided between the support plate and the outer wall panel 2, which can effectively prevent rainwater from seeping into the joint between the rain shield and the outer wall panel 2.

[0042] Reference Figure 4 A baffle 5 is integrally thermoplastically formed downward on the edge of the rain shielding eave 4 away from the exterior wall panel 2. The baffle 5 is parallel to the exterior wall panel 2, and the edge of the baffle 5 away from the rain shielding eave 4 faces downward. After the upper and lower exterior wall panels 2 are installed, the upper part of the lower exterior wall panel 2 should be located between the upper exterior wall panel 2 and the baffle 5. In order to reduce the contact noise between the lower exterior wall panel 2 and the upper baffle 5, a buffer layer 51 is provided between the upper baffle 5 and the lower exterior wall panel 2. In this embodiment, the buffer layer 51 is a polyester fiber sound insulation cotton, and the buffer layer 51 is bonded to the board surface of the baffle 5 facing the lower exterior wall panel 2.

[0043] Reference Figure 1 , 4 A sound insulation layer 3 is filled between the exterior wall panel 2 and the wall 1. In this embodiment, the sound insulation layer 3 is made of PU foam, which has the characteristics of sound absorption, light weight and good elasticity. During installation, glue is applied on both sides of the sound insulation layer 3, and then the exterior wall panel 2 is installed on the wall 1, so that the two sides of the sound insulation layer 3 are bonded and fixed to the wall 1 and the exterior wall panel 2 respectively.

[0044] Reference Figure 2 , 3 , at the same horizontal height, expansion joints are left between two adjacent exterior wall panels 2 and between two adjacent rain shelter eaves 4. On the opposite surfaces between two adjacent exterior wall panels 2 and between two adjacent rain shelter eaves 4, plug-in slots 6 are provided along their respective length directions. A waterproof strip 61 made of rubber is clamped in the plug-in slot 6, and a support rod 62 is also embedded in the waterproof strip 61. When the waterproof strip 61 is clamped in the plug-in slot 6, the axis of the support rod 62 is parallel to the rotation axis 81 of the exterior wall panel 2. The two ends of the support rod 62 are respectively inserted into the plug-in slots 6 on the two adjacent exterior wall panels 2 and the rain shelter eaves 4, so that the exterior wall panels 2 or the rain shelter eaves 4 at the same horizontal height are connected as a whole. Multiple support rods 62 are evenly and parallelly arranged in the waterproof strip 61 to enhance the connectivity between the two adjacent exterior wall panels 2 and the rain shelter eaves 4, so that the two can maintain normal synchronous rotation.

[0045] Reference Figure 2 , 3 In order to further increase the waterproof performance of the gap between the adjacent exterior wall panels 2 and the rain shelter eaves 4, after the waterproof strip 61 is installed, a waterproof sealant 63 is used to fill the gap between the exterior wall panels 2 and the rain shelter eaves 4 away from the wall 1.

[0046] The building is located at the corner and protrudes outward from the wall 1 to form a structural column. The exterior wall panel 2 is close to the edge of the wall 1 and fits the structural column and slides tightly on the structural column.

[0047] The implementation principle of a high-rise building with a green sound environment in an embodiment of the present application is as follows: when the noise passes over the sound barrier on the street and the sound waves are transmitted to the high floors, the sound waves first contact the exterior wall panels 2 outside the wall 1. The exterior wall panels 2 arranged in a scale-like manner in an inclined state increase the distance between the contact point of the sound waves on the exterior wall panels 2 and the indoor space, and the strong sound insulation characteristics of the thicker sound insulation layer 3 between the exterior wall panels 2 and the wall 1 can better isolate the outdoor noise. In addition, when the exterior wall panels 2 receive sound waves, the sound waves will drive the exterior wall panels 2 to vibrate, and the rotation of the exterior wall panels 2 around the hinge axis will consume the sound wave energy accumulated on the exterior wall panels 2, further reducing the outdoor noise. Provide a better green sound environment for the indoor space, so that users can work and rest indoors in a quiet environment.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
