Along with the development of railway transportation, bullet train the most gradually development and application is in railway transportation.Owing to when bullet train runs, speed is big, therefore when it runs, it will produce bigger noise.The baffle of bullet train also becomes research worker focus of attention.
China Patent Publication No. is CN201808249U, entitled a kind of high-speed train noise barrier of innovation and creation, described high-speed train noise barrier includes two lamina rara externas, aramid fiber honeycomb sandwich panel it is provided with between said two lamina rara externa, but this composite board also exists function singleness, the problem of soundproof effect difference.
Therefore, a kind of Multifunction high-speed train noise barrier of invention seems particularly necessary.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of Multifunction high-speed train noise barrier, to solve existing baffle function singleness, and the problem of soundproof effect difference.A kind of Multifunction high-speed train noise barrier, including sandwich plate, intermediate coat, abatvoix and shock reducing structure, described sandwich plate is arranged on train protection hurdle；Described intermediate coat is arranged on the centre of sandwich plate；Described abatvoix is arranged on both sides before and after intermediate coat；Described abatvoix includes that sound absorbing layer, groove and keriotheca, described sound absorbing layer are arranged on the centre position of abatvoix；Described groove is arranged on the lateral mid-point of sound absorbing layer；Described keriotheca is arranged on the left and right sides of groove；Described shock reducing structure is separately mounted to the left and right sides of sandwich plate.
Described sandwich plate specifically uses safety glass sandwich plate, is conducive to improving security protection ability, increases and use function.
Described intermediate coat specifically uses PVB intermediate coat, beneficially soundproof effect so that can reduce the noise quantity penetrating glass.
Described abatvoix concrete mineral wool material plate, is conducive to improving sound-absorbing effect, reduces maintenance cost.
Described sound absorbing layer specifically uses 8 to 16 layers, is advantageously implemented sound-absorbing effect, reduces noise, improves work efficiency further.
Described keriotheca specifically uses honeycomb composite plate material layer, is conducive to provide stable sound-absorbing effect, increases the service life.
Described shock reducing structure specifically uses double-sided belt glue EVA pad, beneficially damping effect so that more conveniently, safely.
