The composite material light-weight sound insulation end wall structure for the rail transit is composed of a supporting body on the front side and a sound insulation body on the rear side, the sound insulation body is provided with a sound attenuation and vibration reduction main structure, and the supporting body comprises a steel framework used for providing mechanical support for an end wall and decoration layers wrapping the front side face, the left side and the right side of the steel framework; a framework cavity used for sound insulation and weight reduction is formed in the steel framework. The steel framework is composed of a front side panel, a left side panel, a right side panel and a rear side panel which are integrally formed, and the rear side panel comprises a left rear folding panel formed by rightward folding of the rear end of the left side panel, a left rear folding panel formed by forward folding of the left rear folding panel, a left rear lap joint panel formed by rightward folding of the left rear folding panel and a right rear lap joint panel formed by rightward folding of the left rear folding panel. The left rear folding panel is formed by bending the rear end of the left side panel leftwards, the right rear folding panel is formed by bending the rear end of the right side panel leftwards, the right rear folding panel is formed by bending the right rear folding panel forwards and backwards, the right rear lap joint panel is formed by bending the right rear folding panel leftwards, and the left rear folding panel and the right rear folding panel are used for supporting the left side and the right side of the sound insulation body respectively. Supporting pieces used for supporting the middle area of the sound insulation body are arranged on the left rear lap joint panel and the right rear lap joint panel. The lightweight end wall has the advantages that the lightweight of the end wall body is realized under the condition that the structural strength requirement and the sound insulation effect of the end wall are met.
本发明公开了一种轨道交通用复合材料轻量化隔音端墙结构,由前侧的支撑主体和后侧的隔音主体构成,隔音主体具有消音减振主结构,支撑主体包括用于为端墙提供力学支撑的钢构架和包覆在钢构架前侧面及左右两侧的装饰层,钢构架内具有用于隔音和减重的构架空腔。钢构架由一体成型的前侧面板、左侧面板、右侧面板和后侧面板构成,后侧面板包括:左侧面板后端向右折转形成的左后折面板、左后折面板向前回折形成的左后回折面板、左后回折面板向右折转形成的左后搭接面板,以及右侧面板后端向左折转形成的右后折面板、右后折面板向前回折形成的右后回折面板、右后回折面板向左折转形成的右后搭接面板,左后折面板和右后折面板分别用于支撑隔音主体的左右两侧,在左后搭接面板和右后搭接面板上设置用以支撑隔音主体的中部区域的支撑件。其优点在于:在满足端墙的结构强度要求和隔音效果的情形下,实现了端墙墙体的轻量化。
