Abstract

The invention relates to a noise prevention and sound insulation barrier for a building structure. The noise prevention and sound insulation barrier comprises a foundation. A plurality of stand columns are fixed to the foundation. A plurality of sound barrier unit boards are fixed between the adjacent stand columns. Each sound barrier unit board comprises two layers of aluminum fiber sheets, two layers of concrete sound absorption boards, two layers of foamed ceramic boards, a cavity, a foldable noise absorption board and a peripheral framework, wherein the aluminum fiber sheets are arranged on the outer surfaces of the two sides of the sound barrier unit board respectively, the two layers of concrete sound absorption boards are arranged in the two layers of aluminum fiber sheets, the two layers of foamed ceramic boards are arranged in the two layers of concrete sound absorption boards, the cavity is formed between the two layers of foamed ceramic boards, the foldable noise absorption board is made of glass wool and arranged in the cavity in a vertically and continuously folded and connected mode, and the two layers of aluminum fiber sheets, the two layers of concrete sound absorption boards and the two layers of foamed ceramic boards are sequentially fixed in the peripheral framework from outside to inside. Serving as a part of the building structure, the noise prevention and sound insulation barrier is simple in structure and low in manufacturing cost and achieves a very good sound absorption and insulation effect.

Description

Technical field [0001] The invention belongs to the field of environmental noise pollution control, and particularly relates to facilities for noise control of building structures in cities, and in particular to an anti-noise and sound insulation barrier for building structures. Background technique [0002] The problem of noise control has attracted more and more attention. Environmental noise is directly related to people's quality of life, and even has an important impact on people's physical and mental health. Especially as the building structure in modern life becomes more and more dense, it is Roads and railways are getting closer, and the impact of road and railway noise on building structures is increasing day by day. Sound barriers are important facilities for noise control in rail transit, elevated roads and expressways. Current sound barriers are usually installed on one or both sides of roads or rail lines, and can be divided into two categories: sound absorption and ...
