Abstract

A scheme of filling a sound-absorbing material between a panel and a back plate is adopted in an existing sound barrier sound-absorbing and sound-insulating unit plate; and the panel is fixed to the back plate in a rivet riveting mode, which leads to great inconvenience to engineering construction. In order to solve the problems, the invention provides an insertion plate type sound barrier sound-absorbing and sound-insulating unit plate. Microporous rock sound-absorbing and sound-insulating plates are adopted as a hard sound-absorbing and sound-insulating panel and a back plate, self-locking mechanisms are formed on the four sides of a metal frame, the middle of the metal frame does not need to be filled with a sound-absorbing material, the insertion plate type sound barrier sound-absorbing and sound-insulating unit plate is very convenient to produce and construct and more excellent in sound-absorbing and sound-insulating performance, and the material is non-toxic, non-irritant and free of any abnormal taste and volatile matter. The cross section of the metal frame on each side is formed by extrusion of aluminum alloy hollow core thin walls, the cross section size is accurate, the processing precision is high, advantages are created for installing a joint sealing material, and the material is light in weight and convenient to use. The cross section has high bending strength, and the unit plate does not shade, does not need painting, is easy to maintain and needs no maintenance.

Description

technical field [0001] The invention relates to a sound-absorbing and insulating unit plate for a sound barrier, in particular to a plug-in type sound-absorbing and insulating unit plate for a sound barrier, which is widely used in urban roads, rail transit, expressway sound barriers and other fields, and can also be used for other noise sources Noise barrier. Background technique [0002] Traffic noise is an unavoidable urban problem in the process of urban traffic development towards high-level, high-speed, elevated and three-dimensional modernization. In order to eliminate or slow down the noise pollution caused by the operation of railways and highways on the sensitive points of the acoustic environment along the line, and to ensure the physical and mental health of the residents along the line and their normal work and life, effective noise reduction measures must be taken. Noise pollution plays a crucial role. The existing sound-absorbing and sound-insulating unit bo...
