Novel bolted fastener for urban rail transit

A novel bolted fastener for urban rail transit is used for effectively reducing the overturning of a steel rail and the dynamic stress of an elastic strip, improving the stability of the steel rail and greatly prolonging the fatigue service life of the elastic strip. The novel bolted fastener comprises an iron backing plate, an elastic strip, an under-rail elastic backing plate, a T-shaped bolt, alocknut, a special-shaped flying-preventing flat washer and insulating damping track gauge blocks, the iron base plate is fixedly installed on the under-rail foundation through anchor bolts, an under-plate elastic base plate is arranged below the bottom face of the iron base plate, and the steel rail is located on the iron base plate. The insulating damping track gauge blocks are located on the top face and the outer side of the steel rail bottom. The lower end of the T-shaped bolt is installed on the iron base plate, the upper portion of the T-shaped bolt is sleeved with the special-shaped anti-flying flat washer an
