Embodiment 2

[0051] Others are the same as in Example 1, the difference is that the protective surface layer 9 includes alkali-free hydrophobic glass fiber cloth and drawn metal mesh, and the rock wool 7 is first wrapped with the alkali-free hydrophobic glass fiber cloth, and then the rock wool 7 is close to the panel The side is wrapped with a drawn metal mesh, and the metal mesh is a diamond-shaped hole with a diagonal of 2mm×4mm.

[0052] The profile frame of the frame-plate fastening type railway metal sound barrier of the present invention is connected with a panel and a backboard by a rivetless fastening method.

[0053] In the frame-plate fastening type railway metal sound barrier of the present invention, the panel is bent and placed between two rubber strips, that is, the panel and the back panel are damped on both sides of the main girder profile, and the load reduction effect is better, and the installation is convenient.

Abstract

The invention relates to a frame plate buckling type railway metal sound barrier, and the model is a TKZP railway metal sound barrier. The frame plate buckling type railway metal sound barrier is suitable for the fields of high-speed railways, intercity railways, passenger transport lines, rail transit and the like, and belongs to the technical field of vibration and noise treatment in environmental protection. The frame plate buckling type railway metal sound barrier mainly comprises a metal sound barrier unit board panel, a back board, a profile framework, a sound absorption component and arubber part, wherein the profile framework is connected with the panel/ the back plate to form a unit plate main body structure by adopting a rivet-free buckling mode. The frame plate buckling type railway metal sound barrier comprises a top unit plate, a standard unit board and a bottom unit board, wherein the top unit board, the standard unit board and the bottom unit board are sequentially arranged on the sound barrier steel stand column from top to bottom. According to the frame plate buckling type railway metal sound barrier, the load of the train pulsation load to the sound barrier and asteel stand column can be effectively weakened, and the load-reducing effect is obvious; and the overall rigidity of a sound absorption material is improved, pressure fiber cement board support is not needed, the weight of the sound barrier plate is reduced, the safety of the sound barrier structure is improved, and the anti-fatigue life is prolonged.

Description

technical field [0001] The invention relates to a frame-plate fastening type railway metal sound barrier, which is a frame-plate fastening type railway metal sound barrier composed of a metal sound barrier unit panel, a back plate, a profile frame and rubber parts, and belongs to the field of environmental protection. Vibration and noise control technology field. Background technique [0002] In recent years, my country has built a large number of 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 barrier systems have been applied. [0003] At present, the high-speed iron metal sound barriers put into use in my country use folded plates to buckle structural metal unit plates, and only thin-walled rubber tubes are used to isolate vibration during installation. However, thin-walled rubber tubes have large permanent compression deformation and will soon lose their effecti...
