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

Embodiment Construction

[0083] Such as figure 1 Shown is a front view of a sound barrier system (including a transparent sound insulation unit panel) comprising a metal sound barrier unit panel of the present invention. Among them, 1 is the H-shaped steel column, 2 is the metal sound barrier unit board with folding plate buckle, and 3 is the transparent sound insulation unit board. The folding-plate snap-fit ​​metal sound barrier unit plate (2) or the transparent sound-insulating unit plate (3) is inserted from the top of two adjacent H-shaped steel columns (1) along the slot, and the fold-plate buckle-fit metal sound barrier unit plate (2) Several pieces are combined with transparent sound-insulating unit panels (3) and several pieces are laminated and clamped between adjacent H-shaped steel columns (1).

[0084] Such as figure 2 As shown, it is a front view of a sound barrier system (without transparent sound insulation unit boards) comprising folding-plate snap-fit ​​metal sound barrier unit bo...

Abstract

The invention provides a sound barrier system comprising folded plate buckling type metal sound barrier unit plates. The folded plate buckling type metal sound barrier unit plates and transparent sound insulation unit plates are inserted between adjacent H-shaped steel columns. The plate body of each folded plate buckling type metal sound barrier unit plate is of a rivet-free buckling type structure and is pressed and meshed through elastic pre-tightening force; and a sound absorption material is clamped and fixed in a closed manner through vertical support section bar lateral clamping groovesand upper and lower side plate trapezoidal clamping grooves inside. The sound barrier system can meet the requirements for lighting and sightseeing of passengers in a train, and the folded plate buckling type metal sound barrier unit plates are light in weight, good in stress, firm in fixation of the sound absorption materials, excellent in fatigue resistance, good in noise reduction effect and easy to assemble.

Description

Technical field: [0001] The invention relates to a sound barrier system comprising a folding-plate fastening metal sound barrier unit plate, including several H-shaped steel columns, and a folding-plate fastening metal sound barrier unit inserted between two adjacent H-shaped steel columns The utility model relates to a board and a transparent sound-insulating unit board, which belong 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 generated, it is necessary to set up sound barriers 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 our country is convex and concave, and the fiber cement board is used as the installation substrate to fix the soun...
