Folded plate buckling type railway metal sound barrier unit plate

Abstract

The invention discloses a folded plate buckling type railway metal sound barrier unit plate, and belongs to the technical field of vibration and noise treatment in the field of environmental protection. The folded plate buckling type railway metal sound barrier unit plate is composed of a bent panel (comprising an upper side plate, a lower side plate, a left side plate and a right side plate), a bent back plate (comprising an upper side plate, a lower side plate, a left side plate and a right side plate), a supporting profile (comprising an end vertical support, a middle vertical support and atransverse support), a sound absorption assembly and a rubber part (comprising a decoupling rubber pad and an inter-plate rubber pad and a bending panel and the bending back plate are buckled in a rivet-free mode and are pressed and meshed through elastic pretightening force). The bending face plate and the bending back plate are buckled in a rivet-free mode and are pressed and meshed through elastic pre-tightening force to form a unit plate main body structure. The supporting sectional materials are clamped in the trapezoidal clamping grooves of the upper side plate and the lower side plate,the deformation resistance of the unit plates is enhanced, the meshing locking stability of the panel and the back plate is enhanced, and the supporting sectional material lateral clamping grooves and the trapezoidal clamping grooves of the upper side plate and the lower side plate achieve closed clamping and fixing of the sound absorption cotton. The folded plate buckling type railway metal sound barrier unit plate is light in weight, good in stress, firm in fixation of the sound absorption cotton, excellent in fatigue resistance, good in noise reduction effect and easy to assemble.

Description

Technical field: [0001] The invention relates to a folded-plate snap-fit ​​type railway metal sound barrier unit plate, which is composed of a bent panel (including upper, lower, left, and right sides), a bent back plate (including upper, lower, left, and right sides) The utility model relates to a folded-plate buckle-fit railway metal sound barrier unit plate composed of supporting profiles, sound-absorbing components and rubber parts, which belongs to the technical field of vibration and noise control in the field of environmental protection. Background technique: [0002] Over the past ten years, my country has built large-scale high-speed railways and put them into operation. In order to solve the noise pollution caused by the operation of high-speed railways, a large number of sound barriers have been set up on both sides of the lines involving noise-sensitive points. [0003] At present, the shell of the high-speed iron metal sound barrier unit plate put into use in ou...

AI Technical Summary

Problems solved by technology

During use, the fiber cement board is prone to cracking, which leads to the instability of the longitudinal structure of the unit board, the concave deformation of the panel and the back board, and the collapse of the sound-absorbing cotton, resulting in the loss of the sound-absorbing function of the sound barrier

At the same time, the installation of fiber cement boards in the unit panel shell will cause the weight of the sound barrier unit panel to be heavy
