Anti-noise sound insulation belt for road

Abstract

The invention relates to the technical field of highway facilities and particularly relates to an anti-noise sound insulation belt for a highway. The sound insulation belt comprises a first sound insulation belt body, a second sound insulation belt body, a plurality of groups of binding devices, an adjusting device, a support box, a plurality of positioning shafts, a connecting plate and an anti-skid pad, wherein an upper part of the support box is sheathed with a fixed plate, and the left part and the right part of the bottom end of the fixed plate are fixedly connected with a support pipe, clamping shafts are sleeved with the supporting pipe, the end, away from the supporting box, of each clamping shaft is fixedly connected with a limiting shaft, the circumferential outer wall of each limiting shaft is sleeved with a first spring, the end, away from the supporting box, of each limiting shaft is fixedly connected with a long plate, the end, close to the supporting box, of each long plate is fixedly connected with a transverse plate, and a top end of the support tube is provided with a guide tube, trigger plates are vertically and slidably connected into the guide pipe, chamfers are arranged on the right portion of the transverse plate, extension plates are arranged at the bottom ends of the trigger plates, an upper plate is arranged on the upper side of the fixing plate, and a bottom end of the upper plate is fixedly connected with the top ends of the trigger plates; the soundproof belt is convenient to mount and demount and high in practicability, and toppling of the soundproof belt is reduced.

Description

technical field [0001] The invention relates to the technical field of road facilities, in particular to a noise-proof and sound-insulating tape for roads. Background technique [0002] As a traffic area for passing vehicles, the highway often whistles during the process of vehicle formation, which affects the residents in the surrounding residential areas. [0003] Patent Publication No. CN111441270A discloses a noise-proof and sound-insulating tape for roads, which is obtained by filling a sound-insulating and sound-absorbing layer between two metal plates, wherein the sound-insulating and sound-absorbing layer is based on polytetrahydrofuran ether glycol, liquid diphenylmethane Diisocyanate polyurethane is foamed to form a porous foam structure, which makes the product have basic sound insulation and sound absorption properties. Most importantly, the introduction of modified mixed fiber and aminopropyltriethoxysilane modified volcanic stone powder, both in It is evenly d...
