Compression type damping fastener
The invention provides a compression type damping fastener, which comprises a base, a floating backing plate, a lateral displacement constraint layer, a vertical displacement constraint layer, a first fixing bolt and a second fixing bolt, wherein the base is arranged on a sleeper, is provided with a base plate of the base and a stop shoulder of the base, and the stop shoulder extends from the base plate of the base; the floating backing plate is arranged on the base; the lateral displacement constraint layer is arranged between the sidewall of the backing plate and the stop shoulder of the base in a clamping manner; the vertical displacement constraint layer is arranged between a base plate of the backing plate and the base plate of the base in the clamping manner; the base is fastened on the sleeper by the first fixing bolt; a steel rail is fixed on the floating backing plate by the second fixing bolt through an elastic device. The compression type damping fastener provided by the invention can increase the ship squat of the steel rail without increasing the lateral displacement of a rail head, can insure the running safety, has higher vibration isolation capability, and is capable of effectively solve the environmental vibration problem caused by the train operation.
