For the line fasteners 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 fasteners and elastic-type elastic fasteners. Between the bottom of the rail and the lower part of the concrete rail, there is a layer of elastic cushion to improve the elasticity of ti linia iti bertikal a direksion; Ti panagtipon ti spike ken ti makimbaba a paset ti kongkreto a riles ket naaramid iti asupre a panagangkla [1]..
Rail buckles are edited, and the joints of the rails and under-rail components are spliced with splicing fittings, spring bars and hooks. According to the material properties, it is divided into two types: rigid and elastic. The rail fastener has a rigid fastener with a rigid buckle and a spring fastener with a spring fastener. The elastic buckle can store the strain energy by means of Ti pre-depormasion, iti kasta ket mangbalbaliw ti kasasaad ti panagbalbaliw ti presion ti buckle. a nainget a pagkapet ket saan a magun-od, isu a ti anti-panagsaksaknap a panagaramid dagiti elastiko a pagkapet ket nangatngato ngem ti daydiay dagiti natangken a pagkapet..
