Description

Technical Field

[0001] This utility model relates to a soundproof curtain wall, and more particularly to a novel soundproof curtain wall. Background Technology

[0002] The construction of elevated highways in cities is increasing, but the resulting noise pollution is also becoming more prominent. This noise pollution includes high-frequency noise and low-frequency resonance pollution. People living in buildings located on both sides of the elevated highways are the main victims of noise pollution. To address this issue, construction companies install soundproof walls (sound barriers) on both sides of elevated highways in densely populated areas. Current sound barriers for elevated highways are mostly vertical panels made of plexiglass and metal frames, with sound-absorbing materials such as sound insulation cotton placed inside the metal frame to achieve sound insulation. While existing sound barriers can reduce noise to some extent, their sound-absorbing effect is limited due to the simplistic approach. Furthermore, plexiglass is subject to aging and needs to be replaced within a certain period. Summary of the Invention

[0003] This utility model provides a novel soundproof curtain wall, which solves the problem that the existing soundproof curtain walls have limited sound absorption and noise reduction effects due to the single sound absorption and noise reduction method.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A novel soundproof curtain wall includes a soundproof panel and a fixed bracket. The soundproof panel is composed of a first partition, a second partition, a sound-absorbing layer, a back panel, and an outer frame. The outer contours of the first partition, the second partition, the sound-absorbing layer, and the back panel are wrapped and fixed by the outer frame. The first partition is provided with a plurality of first sound-absorbing strip holes. A first sound-absorbing plate extends obliquely towards the second partition from one long edge of the first sound-absorbing strip hole. The second partition is provided with a plurality of second sound-absorbing strip holes. A second sound-absorbing plate extends obliquely towards the first partition from one long edge of the second sound-absorbing strip hole. A second sound-absorbing panel extends outwards. The number and position of the first and second sound-absorbing strip holes correspond one-to-one. A reflection zone and a sound-insulating zone are formed between any first sound-absorbing panel and its adjacent second sound-absorbing panel. The two sides of the reflection zone are connected to the two sound-absorbing strip holes, and the two sides of the sound-insulating zone are isolated by two partitions. The fixed bracket consists of a column, two C-shaped rods fixed on the column, and a base. The two C-shaped rods are fixed back to back. The C-shaped rods are provided with a back plate, two side plates, and a slot. The back plate is provided with several obliquely extending elastic pieces. The outer frame of the sound-insulating panel is engaged in the slot and abuts against the elastic pieces.

[0005] This utility model is installed on both sides of an elevated bridge. It employs a method of first installing fixed supports and then installing the sound insulation panels. The columns on the fixed supports are vertically fixed at preset intervals. Then, fixed base blocks are connected between adjacent columns. Two U-shaped rods are fixed to the columns at the factory. The sound insulation panels can then be inserted from top to bottom along the slots on the two U-shaped rods. The back plate of the sound insulation panel faces outwards. The width of the sound insulation panel is slightly larger than the distance between the elastic plates on the left and right sides, thus the elastic plates will be compressed and deformed. The resulting reaction force is used to fix the sound insulation panel, and the base blocks are used for bottom limiting. Therefore, the installation of this utility model is relatively simple, allowing for deviations within the range of movement in the spacing between the columns.

[0006] The noise reduction principle of this invention is as follows: noise generated on the roadside will first collide with the first partition. The first partition can reflect part of the noise. Some sound waves enter the reflection zone through the first sound-absorbing strip holes and are repeatedly reflected between the two sound-absorbing panels. During the continuous reflection process, the sound energy is partially converted into the kinetic energy of material vibration and weakened. Some sound also passes through the first partition and enters the sound insulation zone. The air in the sound insulation zone further attenuates the sound wave vibration through the damping effect. Then, the sound-absorbing layer can receive the remaining sound from the reflection zone and the sound insulation zone. The sound-absorbing layer has a multi-pore structure. The pore structure can disperse the sound wave energy, thereby eliminating part of the noise.

[0007] Furthermore, the outer frame is formed by two horizontal plates and two vertical plates fixedly connected together. The inner side of the vertical plates is provided with a first slot, a second slot, a third slot, and a fourth slot, which are used to engage the first partition, the second partition, the sound-absorbing layer, and the back plate, respectively. This connection and fixing method is relatively simple, suitable for mass production, and helps to improve production efficiency and reduce production costs.

[0008] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model uses multiple methods such as a reflective zone, a sound insulation zone, and a sound-absorbing layer to reduce noise, so the effect is more obvious; 2. This utility model is simple to install and has low requirements for installation accuracy. Attached Figure Description

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example 1: See Figure 1 , Figure 2 and Figure 4 A novel soundproof curtain wall includes a soundproof panel 100 and a fixing bracket 200. The soundproof panel is composed of a first partition 110, a second partition 120, a sound-absorbing layer 130, a back panel 140, and an outer frame 150. The outer contours of the first partition, the second partition, the sound-absorbing layer, and the back panel are wrapped and fixed by the outer frame. The first partition has a plurality of first sound-absorbing strip holes 111, and a first sound-absorbing plate 112 extends obliquely towards the second partition from one long edge of the first sound-absorbing strip hole. The second partition has a plurality of second sound-absorbing strip holes 121, and a second sound-absorbing plate 112 extends obliquely towards the first partition from one long edge of the second sound-absorbing strip hole. A second sound-absorbing panel 122 extends outwards. The number and position of the first and second sound-absorbing strip holes correspond one-to-one. A reflection zone 160 and a sound insulation zone 170 are formed between any first sound-absorbing panel and its adjacent second sound-absorbing panel. The two sides of the reflection zone are connected to the two sound-absorbing strip holes, and the two sides of the sound insulation zone are isolated by two partitions. The fixing bracket consists of a column 210, two U-shaped rods 220 fixed on the column, and a base 230. The two U-shaped rods are fixed back to back. The U-shaped rods are provided with a back plate 221, two side plates 222, and a slot 223. The back plate is provided with several obliquely extending elastic plates 224 (see Figure 5 The outer frame of the sound insulation board is snapped into the slot and abuts against the elastic sheet.

[0017] The sound-absorbing strip holes and sound-absorbing panels on the two partitions are produced by stamping, which has high production efficiency; the elastic plates on the C-shaped rods are also produced by the same production process.

[0018] This embodiment is installed on both sides of an elevated bridge, using a method of first installing the fixed brackets and then installing the sound insulation panels. The columns on the fixed brackets are vertically fixed at a preset spacing, and then fixed base blocks are connected between adjacent columns. Two C-shaped rods are fixed to the columns at the factory. Then, the sound insulation panels can be inserted from top to bottom along the slots on the two C-shaped rods. The back plate of the sound insulation panel is set outwards, and the width of the sound insulation panel is slightly larger than the distance between the elastic plates on the left and right sides. Therefore, the elastic plates will be squeezed and deformed, and the resulting reaction force is used to fix the sound insulation panel. The base blocks are used for bottom limiting. Therefore, the installation of this embodiment is relatively simple, allowing for deviations within the range of movement in the spacing between the columns. To further reduce the generation of gaps, after the sound insulation panels are fixed to the fixed brackets, glue can be applied to the assembly area to further improve the fixing and sound insulation effect.

[0019] The noise reduction principle of this embodiment is as follows: the noise generated on the roadside will first collide with the first partition. The first partition can reflect part of the noise. Some sound waves enter the reflection area through the first sound-absorbing strip holes and are repeatedly reflected between the two sound-absorbing panels. During the continuous reflection process, the energy of the sound is partially converted into the kinetic energy of the material vibration and weakened. Some sound also passes through the first partition and enters the sound insulation area. The air in the sound insulation area further attenuates the sound wave vibration through the damping effect. Then the sound-absorbing layer can receive the remaining sound from the reflection area and the sound insulation area. The sound-absorbing layer has a multi-pore structure. The pore structure can disperse the sound wave energy, thereby eliminating part of the noise.

[0020] See Figure 2 and Figure 3 The outer frame is formed by two horizontal plates 151 and two vertical plates 152 fixedly connected together. The inner side of the vertical plates is provided with a first slot 10, a second slot 20, a third slot 30 and a fourth slot 40, which are used to snap the first partition, the second partition, the sound-absorbing layer and the back panel respectively. This connection and fixing method is relatively simple, suitable for mass production, and helps to improve production efficiency and reduce production costs.

[0021] The first partition, the second partition, the back panel, and the outer frame are all made of aluminum alloy. The distance between the first partition and the second partition is about 2 to 4 centimeters. The first sound-absorbing panel is parallel to the second sound-absorbing panel. The thickness of the sound-absorbing layer is between 0.5 and 1 centimeter. The sound-absorbing layer is specifically a honeycomb panel or sound insulation cotton.

[0022] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
