Abstract
Disclosed is a railway fastener system without an elastic strip. An under-plate elastic backing plate on a gauge backing plate, a backing plate is arranged on the under-plate elastic backing plate, an under-rail backing plate is arranged on the backing plate, and a steel rail is placed on the upper surface of the under-rail backing plate. Fasteners are nylon gauge buckle plates. The nylon gauge buckle plates are made of glass fiber reinforced nylon 66. The lower surfaces of one ends of the nylon gauge buckle plates make contact with the upper surface of one end of the rail bottom of the steel rail and are matched with the inclined plane of one end of the rail bottom of the steel rail. The lower surfaces of the other ends of the nylon gauge buckle plates make contact with the upper surface of the backing plate. Spiral rail spikes sequentially penetrate through the nylon gauge buckle plates, the backing plate, the under-plate elastic backing plate and the gauge backing plate, and then form locking cooperation with a concrete tie. The structure is simple; attaching strength is equal to adopting of the elastic fastener; the cost is reduced by one third; the rusting problem can be effectively relieved; the service life is prolonged; and meanwhile, the effects of noise reducing and damping are achieved, so that the safety and reliability of a vehicle in the driving process are improved.
