For the splicing fittings of concrete under-rail components, it is necessary to solve the problem that the connection between the spike and the concrete and the rigidity of the concrete material are large and the insulation performance is poor. China commonly used gusset-type rigid splicing accessories and elastic-type elastic splicing accessories. Between the bottom of the rail and the lower part of the la rotaia de cemento, un strato de cuscin elastico el vien fornìo par migliorar la elasticità de la vertica diression de la linea; el modo tratà de ła spica e ła rotaia de cemento ła xe ancora el solfore.
A general term for parts such as gussets, spring bars, and hooks for splicing accessories for rails and under-rail components. According to the material properties, it is divided into two types: rigid and elastic. The rail splicing fitting has a rigid splicing fitting with a rigid crimping member, and an elastic splicing fitting with a elastic crimping member. The elastic buckle can store the strain energy by means of pre-deformation, thereby adjusting the fluctuation state of the buckle pressure. Rigid crimping parts are not possible, so the anti-climbing performance of elastic splicing accessories is superior to rigid splicing fittings.
