Description

Combined non-metal sound barrier

Technical Field

The utility model relates to a noise protection device, in particular to a combined non-metallic sound barrier.

Background

Deadening walls, also known as sound barriers, refer to the insertion of a device between the source and the recipient that provides a significant additional attenuation of the sound wave propagation, thereby attenuating the noise contribution in the area of the recipient. The sound insulation and noise reduction composite material is mainly used for sound insulation and noise reduction of highways, expressways, overhead composite roads and other noise sources. The sound barrier is classified into a reflection type sound barrier for pure sound insulation and a composite type sound barrier combining sound absorption and sound insulation, and the latter is a more effective sound insulation method. On highways and highways are the places where the most various types of sound barriers are used.

Sound barriers can be generally classified into metallic sound barriers and non-metallic sound barriers according to the materials from which they are made. One of the nonmetal sound barriers is prepared from a cement concrete material, and the sound barrier is low in manufacturing cost, good in sound insulation effect and very wide in application. At present, the nonmetal sound barrier cell boards that adopt in the application are mostly prefabricated integrative structure, during the installation, directly will become the board and insert and establish in adjacent shaped steel, but the sound barrier of this kind of structure uses the stand too much, will cause the rising of cost certainly, and the sound barrier that uses around some districts, because its requirement for resistance to wind resistance to compression is not high, consequently can reduce the use of stand by a moderate amount, but the length of every cell board is limited, consequently, how to make interconnect between the cell board, just become the technical problem that needs to solve in the sound barrier field.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a combined non-metallic sound barrier.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a modular non-metallic sound protective screen, its includes the stand that sets up according to certain interval and fixes adjacently nonmetal cell board between the stand, the stand is H type stand, and it includes parallel arrangement's two pterygoid laminas and is located connection between the two pterygoid laminas the web of two pterygoid laminas, nonmetal cell board includes panel and backplate, the panel is including the sound absorbing surface part that possesses the sound absorption function and being located the hem at sound absorbing surface part both ends, the backplate is including the sound insulating surface part that possesses the sound insulating function and the hem that is located sound insulating surface part both ends, during the assembled state, hem on the panel with hem on the backplate is inserted simultaneously and is established between the two pterygoid laminas of H type stand.

A cavity is arranged between the panel and the back plate, and a sound absorption material is arranged in the cavity.

The panel and the back plate are mutually attached, and the panel is a porous ceramsite plate.
