Abstract

The invention relates to an aluminum perforated sound-absorption and insulation plate which comprises a steel post. The middle part of the steel post is a transparent PC (polycarbonate) plate and the upper portion and the lower portion are aluminum perforated plates which are connected with the steel post in a compact mode through a Z-shaped spring fastener. The aluminum perforated plate comprises an aluminum perforated panel,glass cottons and a galvanized steel rear panel with a V shape. The connection part of the upper and the lower of a frame composed of the aluminum perforated panel and the galvanized steel rear panel with a V shape is an embedded concave and convex groove structure. The aluminum perforated sound-absorbing plate is reasonable in structure, large in strength, light in weight, good in sound-absorbing effect and can save materials.

Description

technical field [0001] The invention relates to various road and rail traffic and high-speed rail noise reduction devices, in particular to a sound-absorbing barrier board. Background technique [0002] With the progress of society and the development of cities, people's living standards continue to improve, urban traffic has become the most closely related issue. The construction of a large number of expressways and the opening of urban light rail and high-speed railways have brought great convenience to our travel, but at the same time, residents living near these expressways, light rails and high-speed railways suffer from traffic noise. In order to improve the living environment of citizens, relevant departments have installed various sound-absorbing barriers on both sides of the road and along the light rail and high-speed rail lines. [0003] The current sound-absorbing barrier panel is generally provided with a front panel and a back panel. Both the panel and the bac...
