INDIRECT REINFORCEMENT OF REINFORCED CONCRETE UNDER-RAIL BASE IN THE ZONE OF FIXED PARTS

摘要

The utility model relates to the elements of a reinforced concrete base and fastenings of a railway, tram track and subway track, to indirect reinforcement of a reinforced concrete sub-rail base in the installation area of embedded parts, namely, dowels of intermediate rail fastenings with a reinforced concrete base;The technical result, to which the utility model is aimed, is to increase the crack resistance of the reinforced concrete base in the area of the under-rail platform from splitting and radial cracks directed from the dowel inlet, as well as to ensure uniform filling of the concrete mixture between the spiral and the dowel, which increases the resistance to pull-out dowels from a reinforced concrete base and its durability.;The specified technical result is achieved by the fact that indirect reinforcement is proposed for a reinforced concrete sub-rail base in the installation zone of embedded parts, namely dowels of intermediate rail fastenings with a reinforced concrete base, to be used in the form of a spiral in the form of an inverted cone with attachment in the lower part of the dowel, which allows the spiral to be fixed in the working area of the concrete base, while maintaining the protective layer of concrete in the sub-rail base at the inlet of the dowel. As a result, a reliable fixation of the spiral on the dowel is ensured during the manufacture of a reinforced concrete base, namely, the alignment of the holes and a guaranteed symmetrical geometric gap between the dowel and the spiral are ensured.
