Totally-closed sound barrier with novel structure

Abstract

The invention provides a totally-closed sound barrier. The profile steel of a roof part is deformed steel and comprises a web plate, an upper wing plate, a lower wing plate and an additional wing plate, the additional wing plate is positioned between the upper wing plate and the lower wing plate, an opaque unit plate or a transparent unit plate is directly placed on the adjacent additional wing plate of the deformed steel, a pressing plate is pressed on the upper wing plate of the deformed steel and the end portion of the opaque unit plate or the transparent unit plate, and a bolt penetrates through the additional wing plate upwards and then is fixed through a nut. By additionally arranging the additional wing plate, the upper surface of the roof part is in a flat state, the overall attractiveness is improved, follow-up cleaning operation or work such as design and installation of a cleaning device is facilitated, in addition, a screen body is fixed to the profile steel of the roof part through the bolt and the pressing plate, water accumulation and water leakage are avoided, rainwater or dew can be prevented from permeating the periphery of the bolt, and the service life of the bolt is prolonged.

Description

technical field [0001] The invention relates to a noise protection device, in particular to a fully enclosed sound barrier with a new structure. Background technique [0002] As an effective traffic noise blocking device, the fully enclosed sound barrier is widely used in municipal, railway and other roads with high traffic noise and high aesthetic requirements. Because of its good noise blocking performance and high environmental beautification effect, it is therefore It has become the first choice for noise reduction in many urban traffic roads. The upper part of the existing fully enclosed sound barrier generally adopts a transparent or opaque sound-absorbing screen body. For the sake of aesthetics, most of them use transparent unit boards. The transparent unit boards generally use PC boards or acrylic boards. Now, the entire transparent unit board is usually first Lap on the upper surface of the adjacent H-shaped steel, and then fix it with bead. The disadvantage of th...

Problems solved by technology

The disadvantage of this structure is that the transparent unit plate is too large, once it is damaged, it needs to be removed as a whole. During the installation process, there are many problems such as a large number of bolts and complex on-site construction, and the surface of the fully enclosed sound barrier of this structure is generally uneven. Uneven, not only prone to water seepage, but also not conducive to subsequent cleaning and other work
