Description

Technical Field

[0001] The invention relates to the technical field of soundproofing walls in construction engineering, in particular to a modular soundproofing wallboard. Background Art

[0002] Noise insulation walls (also called sound barriers) are mainly used for noise insulation and noise reduction in transportation and municipal facilities such as highways, elevated composite roads, urban light rail subways, etc., to control the impact of traffic noise on nearby urban areas, and can also be used for noise insulation and noise reduction in factories and other noise sources. It can help reduce the impact of driving noise on nearby residents and protect the hearing system of factory workers with a noisy working environment.

[0003] The existing soundproof wall usually uses sound insulation materials added inside the wall to block sound waves, but this method can only filter out the noise of a fixed Hz frequency band that the sound insulation material can soundproof, and the noise of other Hz frequency bands may not be blocked; and if all frequency bands are simply filled with materials, it will cause unnecessary waste of resources, because the working environment is always distributed in certain Hz frequency bands, not full frequency band coverage; at the same time, if the decibel of the noise is large, even the thickest sound insulation material may not be able to block it, not to mention the waste of space for materials that cannot block its specific frequency band; for this reason, a modular soundproof wall panel is proposed.

[0029] In this embodiment, specifically: the front surface of the honeycomb sound absorbing board 2 is bonded with a honeycomb sound absorbing layer 201; the arrangement rule of the hexagonal grooves of the honeycomb sound absorbing layer 201 affects the penetration consumption of noise, absorbs high-decibel noise, converts vibration into deformation energy of its core material, causes vibration of air and material, and due to friction and viscous resistance, part of the sound energy of the noise is converted into heat energy, which can reduce decibels and stabilize the noise frequency band. The specific material is petroleum fiber.

[0030] In this embodiment, specifically: five ultrasonic sound absorbing panels 4 are slidably connected to the inner wall of the slide groove 601, and four infrasonic sound absorbing panels 5 are slidably connected to the inner wall of the slide groove 601; after a stable noise frequency band, ultrasonic waves will be absorbed by the ultrasonic sound absorbing panels 4, and infrasonic waves will be absorbed by the infrasonic sound absorbing panels 5; the staff determines which frequency band the main noise depends on and whether the decibel level is sufficient according to the working environment of the wall installation, and then selectively disassembles and assembles the number of ultrasonic sound absorbing panels 4 and infrasonic sound absorbing panels 5.

[0031] In this embodiment, specifically: the material of the ultrasonic sound absorbing panel 4 is semi-rigid glass wool wedges, and the material of the infrasonic sound absorbing panel 5 is sound absorbing cotton.

[0032] In this embodiment, specifically: handles 401 are welded on both sides of the ultrasonic sound absorbing board 4; since the material of the ultrasonic sound absorbing board 4 is semi-rigid glass wool wedges, which is a high-density and fragile material, it is easy to cause damage when manually pulled out, so the welding handles 401 help the staff to disassemble and assemble steadily.

[0037] Working principle or structural principle: When noise is transmitted to the modular sound insulation wall panel of the present invention, the arrangement rule of the hexagonal grooves of the honeycomb sound-absorbing layer 201 first affects the noise penetration consumption, absorbs high-decibel noise, and converts the vibration into the deformation energy of its core material, causing vibration of air and material. Due to friction and viscous resistance, part of the sound energy of the noise is converted into heat energy, which can not only reduce the decibel but also stabilize the noise frequency band.

[0038] After passing through a stable noise frequency band, ultrasonic waves will be absorbed by the ultrasonic sound-absorbing board 4, infrasonic waves will be absorbed by the infrasonic sound-absorbing board 5, and normal noise frequencies will be absorbed by the silencer block 701; the staff will determine which frequency band the main noise depends on and whether the decibel level is sufficient according to the working environment of the wall installation, and then selectively disassemble and assemble the number of ultrasonic sound-absorbing boards 4, infrasonic sound-absorbing boards 5, third partitions 8 and silencer blocks 701.
