Vibration reduction fastener system
The invention provides a vibration reduction fastener system which comprises a lower base plate, an upper base plate and a middle elastic layer, the lower base plate is of a frame type structure, the middle of the lower base plate is hollow, the middle elastic layer and the upper base plate are installed in a frame of the lower base plate, and gaps are formed between the outer sides of the left and right ends of the upper base plate and the inner sides of the left and right ends of the lower base plate. And a wedge-shaped plug block is arranged in the gap. The wedge-shaped plug block locks the upper base plate and the lower base plate and is used for limiting transverse and longitudinal displacement of the upper base plate, the lower base plate is arranged to be of a frame structure so that the vibration reduction fastener can have the low installation height, the installation height can be kept consistent with that of a common fastener, and anchor bolts matched with the vibration reduction fastener are also kept consistent with that of the common fastener. The middle elastic cushion layer can be replaced on the premise that anchor bolts do not need to be detached, smaller rail head transverse displacement of the vibration reduction fastener is achieved on the premise that the requirement for small vertical rigidity is met, and a rail system has better safety performance on the premise that the requirement for better vibration reduction performance is met.
本发明提供一种减振扣件系统，包括下垫板、上垫板、中间弹性层，下垫板设置为框架型结构，下垫板的中间设置为中空，中间弹性层和上垫板安装在所述下垫板的框架内，上垫板左右两端外侧与下垫板左右两端内侧之间形成间隙，在所述间隙内安装楔形塞块。楔形塞块对上垫板和下垫板进行锁紧，用于限制上垫板横向和纵向的位移，并且将下垫板设置为框架结构使得减振扣件具有低的安装高度，安装高度可与普通扣件保持一致，且减振扣件配套的锚固螺栓也与普通扣件保持一致，不需要拆卸锚固螺栓的前提下更换中间弹性垫层，且在满足较小的垂向刚度前提下赋予减振扣件更小的轨头横向位移，也即在满足更好的减振性能前提下轨道系统具有更好的安全性能。
