Abstract
The utility model relates to a resonant cavity sound barrier is with nonmetal compound sound absorption and insulation board, including facial porous acoustic absorber, back supporter, reinforcing bar net and resonant cavity, the resonant cavity sets up between porous acoustic absorber of face and back supporter, and the reinforcing bar net sets up inside the supporter of back, and the both sides of back supporter are corresponding boss and the recess of being equipped with respectively. The compound sound absorption and insulation board intensity of this nonmetal is high, it is good to inhale the defening effect, and the resonant cavity has effectively reduced the concrete use amount of back supporter, has reduced the weight of inhaling the sound insulation cell board, has made things convenient for transportation and the installation in the engineering.
Description
Technical field
The utility model discloses a kind of nonmetal compound Felt of sound barrier, be specifically related to a kind of nonmetal compound Felt of high speed railway sound barrier concrete with resonant cavity.
Background technology
Along with developing rapidly of high-speed railway, sound pollution is day by day serious, and sound barrier takes up an area few, and fabrication and installation are quick, and construction investment is suitable for, it has also become the important measures that traffic noise controls.Sound barrier is a kind of for absorbing and isolating the through sonic propagation of noise source, the sound absorption arranged between noise source and receiver and sound insulation shielding harness, it makes recipient be placed in acoustic shadow, thus the influence of noise weakened in the certain area at recipient place, sonic propagation of making an uproar there is good isolation effect.Sound barrier is widely used in countries in the world, especially the developing rapidly of high-speed railway in recent years, high speed railway sound barrier has been also carried out many research by various countries, has been also carried out deep research and substantial amounts of practice in the design and construction of high speed railway sound barrier.
Utility model content
The utility model proposes a kind of nonmetal compound Felt of resonant cavity sound barrier, this nonmetal compound Felt intensity height, light weight, sound absorption are effective.
To achieve these goals, this utility model is achieved through the following technical solutions:
A kind of resonant cavity sound barrier is with nonmetal compound Felt, including face porous absorber, back supports, bar-mat reinforcement and resonant cavity；Described resonant cavity is arranged between face porous absorber and back supports, and described bar-mat reinforcement is arranged on inside back supports, and the both sides of described back supports are correspondingly provided with boss and groove respectively.
Further, to be parallel to the broadside of nonmetal compound Felt evenly distributed for described resonant cavity.
Further, described resonant cavity is through in cavity along the long limit of nonmetal compound Felt.
Further, described bar-mat reinforcement is along being parallel at least one reinforcement welding composition that nonmetal compound Felt surface is evenly distributed, increasing Felt integral rigidity.
This utility model resonant cavity sound barrier is with nonmetal compound Felt, and it has the beneficial effects that:
1, intensity is high: this nonmetal compound Felt back supports adopts high-strength concrete to build and molding, and internal filling bar-mat reinforcement, bulk strength is guaranteed；
2, sound absorption is effective: this Felt energy-dissipation structure contains face porous absorber and resonant cavity, is effectively increased sound absorption effect
3, light weight: resonant cavity effectively reduces the concrete of back supports and makes consumption, reduces the weight of sound absorption cell board, facilitates the transport in engineering and installation.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is this utility model resonant cavity sound barrier schematic cross-section with nonmetal compound Felt.
1-face porous absorber, 2-back supports, 3-bar-mat reinforcement, 4-resonant cavity, 5-boss, 6-groove.
Detailed description of the invention
This utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of resonant cavity sound barrier is with nonmetal compound Felt, as it is shown in figure 1, include face porous absorber 1, back supports 2, bar-mat reinforcement 3 and resonant cavity 4；Resonant cavity 4 is arranged between face porous absorber 4 and back supports 2, and the broadside that resonant cavity 4 is parallel to nonmetal compound Felt is evenly distributed and through in cavity along the long limit of nonmetal compound Felt；It is internal that bar-mat reinforcement 3 is arranged on back supports 2, along being parallel at least one reinforcement welding molding that nonmetal compound Felt surface is evenly distributed, increases Felt integral rigidity；The both sides of back supports 2 are correspondingly provided with boss 5 and groove 6 respectively.The boss 5 of Felt and groove 6 can improve Felt seal each other when sound barrier is installed, and strengthen defening effect, it is prevented that leakage sound；Felt face porous sound absorber 1 has sound absorbing capabilities, and resonant cavity 4 plays power consumption effect by hole channel connection in the middle of porous absorber, improves Felt sound absorption effect.
The explanation of above example is only applicable to help to understand principle of the present utility model；Simultaneously for one of ordinary skill in the art, according to this utility model embodiment, all will change in detailed description of the invention and range of application, in sum, this specification content should not be construed as restriction of the present utility model.
