Description

Composite nonmetallic sound barrier unit plate Technical Field The utility model belongs to the technical field of sound barriers, and particularly relates to a composite nonmetallic sound barrier unit board. Background At present, a domestic nonmetallic sound barrier of a high-speed railway is mainly made of various concrete materials, the sound barrier is generally made of an inserted structure of an H-shaped steel upright post by inserting a unit plate, a traditional concrete sound barrier unit plate is formed by casting in a fractional manner, the structure is divided into an open-pore panel, a non-open-pore backboard and an internal sound absorber, the manufacturing process is that the open-pore panel is cast firstly, then sound-absorbing rock wool is paved, then the whole sound-absorbing surface is wrapped by casting back concrete, and demoulding and forming are carried out after concrete is solidified, and later maintenance is carried out. The existing nonmetallic sound barrier is mostly formed by compounding concrete rock wool, cracks of a concrete structure are expanded until the cracks are broken in the using process, so that steel bars of the concrete are corroded, the surfaces of the concrete are cracked, and the safety risk is caused. Disclosure of utility model The utility model aims to provide a composite nonmetal sound barrier unit board with a sound absorption panel, which is relatively floating relative to a back board, is impact-resistant and fatigue-resistant, and has the characteristics of high structural strength, lasting vibration and noise reduction effect and long service life. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a composite nonmetallic sound barrier unit board is characterized by comprising a back board and a panel, wherein the back board is cast by concrete, the panel is made of ceramic particle sound absorption materials, the back board is connected with the panel through a damping deformation layer, and the panel can float in a damping way relative to the back board after receiving load impact.
