Abstract
The utility model belongs to the field of traffic network noise reduction and particularly relates to a slant hole type acoustic board for a traffic network. The slant hole type acoustic board comprises a sound absorption body support plate and is characterized in that a convex groove is formed in the top of the sound absorption body support plate; a concave groove is formed in the bottom of the sound absorption body support plate; the convex groove and the concave groove correspond to each other in shape and size; a sound absorption body is arranged in the sound absorption body support plate; sound absorption holes are formed in the sound absorption body support plates; and the sound absorption holes adopts slant hole type strip-shaped structures arranged at equal intervals. The slant hole type acoustic board for the traffic network has the advantages of simple structure, convenience in installation, noise reduction, remarkable sound absorption effect, light mass and high strength; and as the sound absorption holes adopts the slant hole type structures, the slant hole type acoustic board is suitable to be mounted and used on a noise damping wall of the traffic network.
Description
Technical field
The utility model belongs to traffic network noise reduction field, particularly a kind of traffic network oblique hole type acoustical board that is used for.
Background technology
At present, eliminate noise and become one of urgent task in the current Communication and Transportation Engineering.The noise that is produced during vehicle operating on the traffic highway has had a strong impact on people's normal life.The homininoxious cardiovascular system of this noise has improved the hypertension incidence rate; Influence people's nervous system, make people's irritability, irritability; The influence sleep causes tired; The hearing ability that long-time back energy loss victimizes.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of traffic network oblique hole type acoustical board that is used for is provided, eliminates noise, improve people's quality of life.
The utility model solves the technical scheme that its technical problem adopted: the said traffic network oblique hole type acoustical board that is used for; Comprise the sound absorber gripper shoe, it is characterized in that: sound absorber gripper shoe top is provided with convex slot, and sound absorber gripper shoe bottom is provided with Baltimore groove; Baltimore groove shape, size and convex slot shape, big or small corresponding; Sound absorber gripper shoe inside is provided with sound absorber, and the sound absorber gripper shoe is provided with the sound absorption hole, and the sound absorption hole is the strip-like-shaped structure that oblique hole type is equidistantly arranged.
Convex slot and Baltimore groove mainly are for when traffic network oblique hole type acoustical board is installed, the convenient connection; The sound absorption hole mainly is to give sound absorber with noise transfer, the protection sound absorber; Sound absorber has the function of absorption of noise; The sound absorber gripper shoe mainly plays support and the effect of protection sound absorber.
The inclination angle in said sound absorption hole is 45 °～80 °.
Operating principle and process:
When mounted, earlier selected installation site is installed the utility model then and is connected into the sound absorption body of wall.In connection process, the convex slot of an acoustical board is embedded in another piece acoustical board Baltimore groove, by that analogy.When the utility model after the installation of precalculated position, the noise that on traffic route, is produced passes to sound absorber through the sound absorption hole, thereby reaches the purpose of eliminating noise.
The beneficial effect that the utility model had is:
The utility model is simple in structure, and is easy for installation, reduces noise, and acoustically effective is obvious, light weight, and intensity is high; Because the sound absorption hole is the oblique hole type structure, installs and uses so be applicable to traffic network noise reduction wall top.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1.
Among the figure: 1, convex slot, 2, the sound absorber gripper shoe, 3, the sound absorption hole, 4, sound absorber, 5, Baltimore groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
Of Fig. 1, be used for traffic network oblique hole type acoustical board and comprise sound absorber gripper shoe 2, sound absorber gripper shoe 2 tops are provided with convex slot 1; Sound absorber gripper shoe 2 bottoms are provided with Baltimore groove 5; Baltimore groove 5 shapes, size and convex slot 1 shape, big or small corresponding, sound absorber gripper shoe 2 inside are provided with sound absorber 4, and sound absorber gripper shoe 2 is provided with sound absorption hole 3; Sound absorption hole 3 is the strip-like-shaped structure that oblique hole type is equidistantly arranged, and it is 75 ° that present embodiment is selected the inclination angle in sound absorption hole 3 for use.
When mounted, earlier selected installation site is installed the utility model then and is connected into the sound absorption body of wall.In connection process, the convex slot 1 of an acoustical board is embedded in another piece acoustical board Baltimore groove 5, by that analogy.When the utility model after the installation of precalculated position, the noise that on traffic route, is produced passes to sound absorber 4 through sound absorption hole 3, thereby reaches the purpose of eliminating noise.
