In addition, a partition board used for separating, blocking and absorbing sound cotton in the sound barrier unit board is usually made of a cement fiber board material, and is not favorable for light-weight design requirements due to large weight.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the defects of the prior art are overcome, and the metal sound absorption and insulation barrier for the railway high-speed road is reliable in connection structure and simple and convenient to install.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a railway highway is with inhaling sound insulation metal sound barrier, includes H type stand and inserts the sound barrier body of establishing between two adjacent H type stands, the sound barrier body include panel and the backplate of lock on the panel, the upper and lower end of panel sets up spacing fastener I and spacing fastener II respectively, spacing fastener set up toward the sunken draw-in groove in both ends, support piece is established to the card in the draw-in groove, set up the sound absorption cotton in the space that support piece and panel formed, support piece and backplate formed cavity are the noise elimination cavity, set up the baffle between support piece and the sound absorption cotton, the baffle on set up the perforation, the junction of sound barrier body and H type stand set up the bolster.
Furthermore, limiting fastener I pass through the mounting and be fixed mutually with panel, backplate.
Furthermore, the supporting piece, the limiting fastener II and the panel are fixed through the fixing piece.
Furthermore, the baffle on set up a plurality of strengthening ribs, the strengthening rib towards cotton one side arch of sound absorption.
Furthermore, the aperture of the perforation is 3mm, and the aperture ratio is more than 20%.
Further, the panel is made of aluminum alloy plates, and the partition plate and the back plate are made of galvanized steel plates.
Further, the sound absorption cotton is polyester fiber cotton.
Furthermore, the buffer part is made of ethylene propylene diene monomer.
The utility model discloses a railway is sound barrier with inhaling heat insulation metal for highway, its beneficial effect is: the upper and lower end of panel sets up spacing fastener I and spacing fastener II respectively to fixed support piece, and make spacing fastener and panel and backplate fixed connection through the mounting, overcome the easy not hard up defect that drops of current support piece, set up the strengthening rib on the baffle, guaranteed the intensity of baffle on the one hand, play the support fixed action to the sound absorption cotton on the other hand, simple structure reliably easily realizes.
