Splicing type ballast bed sound-absorbing board and acoustic sound-absorbing assembly
The invention discloses a splicing type ballast bed sound-absorbing board and a sound-absorbing assembly, the splicing type ballast bed sound-absorbing board comprises a sound-absorbing board block, the sound-absorbing board block is provided with an upper surface used for absorbing sound, a lower surface arranged opposite to the upper surface, and one or two side surfaces arranged opposite to each other and used for facing the adjacent sound-absorbing board block; one of the upper surface and the lower surface of the same sound absorption plate is a lap joint surface, and a lap joint concave surface connected with the side surface is arranged at the edge position, close to the side surface, of the lap joint surface. The sound-absorbing plates are provided with the lap joint concave surfaces, every two adjacent sound-absorbing plates can be connected into a whole only by arranging the vertical connecting pieces, the structure is simple, connection is stable, when one sound-absorbing plate needs to be disassembled and repaired, only one sound-absorbing plate or at most three sound-absorbing plates can be disassembled, the sound-absorbing plate to be disassembled and repaired can be disassembled, and operation is convenient.
本发明公开了一种拼搭式道床吸音板及吸音组件，包括吸音板块，所述吸音板块具有用于吸音的上表面、与所述上表面相背设置的下表面以及用于朝向相邻吸音板块的一个或相背设置的两个侧表面，同一所述吸音板块的上表面和下表面中，其中一者为搭接表面，所述搭接表面靠近所述侧表面的边缘位置设有与所述侧表面相接的搭接凹陷面。通过将吸音板块设置搭接凹陷面，只需设置竖向连接件，即可将相邻两个吸音板块连接为一体，结构简单，连接稳固，当需要拆修其中一处吸音板块时，可仅拆卸一个吸音板块，或最多拆卸三个吸音板块，即可实现待拆修的吸音板块的拆除，操作方便。
