Description
Technical field
This utility model relates to fixed buildings, road and bridge through the absorption of the noise of aerial conduction or reflection unit, espespecially a kind of road sound-proofing board.
Background technology
Progress along with the development science of society, Traffic Net is more and more flourishing, cause a lot of express passway, overpass from life residential quarter increasingly close to, the car, the engineering truck that gallop at all speed at a high speed all can bring substantial amounts of noise pollution, causing the resident living near roads by huge puzzlement, the baffle of prior art is all to use steel or composite bed made of iron, and weight is big, installing inconvenience, soundproof effect is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, and the road sound-proofing board of light weight, by the compound use of a large amount of organic materials, the quality of baffle is greatly reduced, designed by multi-level density structure, SATT can be effectively formed, strengthen soundproof effect.
For achieving the above object, this utility model be the technical scheme is that a kind of road sound-proofing board, including body, first baffle plate, first open slot, second baffle, second open slot, third gear plate, rock wool layer, glass cotton layer, polyurethane foam, vacuum chamber, it is characterized in that: body right-hand member is provided with the first baffle plate with some level the first open slots, body left end is provided with vacuum chamber, polyurethane foam from left to right it is disposed with between vacuum chamber and the first baffle plate, rubber layer, rock wool layer, third gear plate, glass cotton layer, second baffle, some second open slots it have been horizontally disposed with on second baffle, first open slot and the second open slot are for being crisscross arranged, some 3rd open slots it have been horizontally disposed with on third gear plate, 3rd open slot and the first open slot are in same level.
As further improvement of the utility model, being provided with foamed silica gel layer on the left of described vacuum chamber, foamed silica gel layer thickness is 2 centimetres.
As further improvement of the utility model, being provided with Air Filter between described first baffle plate and second baffle, the left and right both ends of the surface of Air Filter are respectively arranged with some hairbrush.
As further improvement of the utility model, on the right side of described first baffle plate, it is provided with, between two the first adjacent open slots, the projection that cross section is isosceles trapezoid.
Operation principle:
nullThis utility model is designed by the simplest structure，Effectively road noise can be carried out effective separate absorption，By the projection arranged on the right side of the first baffle plate, sound wave is carried out effective reflection-absorption，First baffle plate、Second baffle、The first open slot of design it is horizontally staggered on third gear plate、Second open slot、3rd open slot effectively can carry out decay interference to sound wave，The glass cotton layer that density increases successively simultaneously、Sound wave high band can effectively be absorbed by the fibrous through hole of rock wool layer，Stop the transmission of sound wave further，The barrier design of rubber layer has the effect of good damping shock absorption，The effective impact reducing air-flow，The design of polyurethane foam can fully absorb the noise of low band，There is the most anti-tampering performance，The design of vacuum chamber can sufficiently stop sonic propagation，The foamed silica gel layer simultaneously arranged on the left of vacuum chamber can effectively prevent vacuum chamber to be knocked and cause breakage，The combination of Air Filter and hairbrush simultaneously can effectively prevent dust from entering rock wool layer or glass cotton layer is blocked its intermediate gaps and caused sound-absorbing effect to reduce，Also can play the effect of absorbing sound and lowering noise simultaneously.
This utility model compared with prior art has the advantages that
1, this utility model is designed by the simplest structure, effectively road noise can be carried out effective separate absorption, by the projection arranged on the right side of the first baffle plate, sound wave is carried out effective reflection-absorption, be horizontally staggered the first open slot of design on first baffle plate, second baffle, third gear plate, the second open slot, the 3rd open slot effectively can carry out decay interference to sound wave, sound wave high band can effectively be absorbed by density increases successively simultaneously glass cotton layer, the fibrous through hole of rock wool layer, stops the transmission of sound wave further；
2, the barrier design of rubber layer has the effect of good damping shock absorption, the effective impact reducing air-flow, the design of polyurethane foam can fully absorb the noise of low band, there is the most anti-tampering performance, the design of vacuum chamber can sufficiently stop sonic propagation, the foamed silica gel layer simultaneously arranged on the left of vacuum chamber can effectively prevent vacuum chamber to be knocked and cause breakage；
3, the combination of Air Filter and hairbrush simultaneously can effectively prevent dust from entering rock wool layer or glass cotton layer is blocked its intermediate gaps and caused sound-absorbing effect to reduce, and also can play the effect of absorbing sound and lowering noise simultaneously.
