Abstract
The utility model belongs to the field of traffic road network noise reduction and particularly relates to a straight hole type sound absorbing plate for a traffic road network. The straight hole type sound absorbing plate comprises a sound absorbing body support plate and is characterized in that the top of the sound absorbing body support plate is provided with a convex groove, the bottom of the sound absorbing body support plate is provided with a concave groove, the concave groove corresponds to the convex groove in shape and size, a sound absorbing body is arranged inside the sound absorbing body support plate, and sound absorbing holes are arranged in the sound absorbing body support plate and are in an equidistant straight hole type strip structure. The straight hole type sound absorbing plate has the advantages that the structure is simple, the installation is convenient, the noise is reduced, the sound absorbing effect is obvious, the mass is light, and the strength is high; and because the sound absorbing holes are in a straight hole type structure, the straight hole type sound absorbing plate is suitable for being installed and used at the lower part of a sound attenuation wall of the traffic road network.
Description
Technical field
The utility model belongs to traffic network noise reduction field, particularly a kind of traffic network straight hole formula 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 straight hole formula 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 straight hole formula 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 that the straight hole formula is equidistantly arranged the strip-like-shaped structure.
Convex slot and Baltimore groove mainly are for when traffic network straight hole formula 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.
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.After the utility model installation, 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 a straight hole formula structure, installs and uses so be applicable to traffic network noise reduction wall bottom.
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 straight hole formula acoustical board and comprise sound absorber gripper shoe 2, sound absorber gripper shoe 2 tops are provided with convex slot 1, and 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, and sound absorption hole 3 is the strip-like-shaped structure that the straight hole formula is equidistantly arranged.
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.After the utility model installation, the noise that on traffic route, is produced passes to sound absorber through the sound absorption hole, thereby reaches the purpose of eliminating noise.
