FIELD: construction, road engineering. ^ SUBSTANCE: invention is related to railway transport, namely to joint bars and methods of their application in process of jointed track installation and may be used in construction and repair of railway and tramway tracks, subway, and park amusements with application of railroad elements. Joint bar that connects giving and receiving railroad rails with creation of rail joint is made of two parts, connection of one of which is arranged as undetachable (in second version - with guaranteed interference). In the first version joint is riveted or welded. Method for application of joint bar including its fixation to webs of giving and receiving rails, consists in the fact that for fixation joint bar is used made of two parts, connection of one of which with rail is arranged as undetachable or with guaranteed interference. ^ EFFECT: increased efficiency of expenses for transportation of passengers and freight on railway, in reduction of impact loads and hazardous noise effect at environment, reduction of manhours for creation of rail joint, increased service life of railroad, rolling stock, subway wagons. ^ 5 cl, 2 dwg |
