Abstract

1349854 Slipform paver for railway tracks JOHN LAING & SON Ltd 23 July 1971 [23 July 1970] 35786/70 Heading E1G A concrete track having a row of fixtures embedded therein with their upper ends accessible for anchoring railway attachments thereto is formed by advancing a slipform paver 1 having a profiler 7 and continuously introducing a string of the fixtures 21 separated by spacers 22 into guide channels 8, 9 adjacent the underside of the profiler 7 so that the lower part of the fixtures becomes embedded in the concrete. The spacers are subsequently removed and re-used. As shown, the string is fed into an inverted channel member 12 which guides it to the channels 8, 9 which are formed in the profiler so that the upper ends of the fixtures 21 stand proud of the track. The fixtures 21 each abuts a collar 23 with a complementally shaped recess 35 and a set screw 37 and the string is mounted on a separably sectioned dowel rod 24. The spacer 22 and collar 23 have cross-sections complemental to that of the channels 8, 9. The profiler 7 may comprise a plate or a vibrating beam. A reinforcement cage 19 may be fed over a pivotal support 17 into the concrete.
