Definitions

• the invention relates to an installation method for a fixed railroad track, in which the concrete sleepers supporting the tracks are adjusted in position in a concrete trough and embedded in longitudinal paving in a casting compound by first preassembling the tracks with the sleepers to form a track grate that opens onto The top edge of the rail is adjusted and then cast in.
• the sleepers are first individually adjusted and the longitudinal reinforcements are subsequently inserted through transverse holes in the concrete sleepers.
• this method also has disadvantages in the laborious introduction of the longitudinal reinforcements into transverse holes in the concrete sleepers that have to be provided.
• the invention is therefore based on the object of developing the installation method of the type mentioned in such a way that it enables simpler and more precise laying of the sleepers and rails.
• the use of two-block concrete sleepers with two reinforced individual blocks comprising structural steel rods which run essentially parallel to the sleeper axis and are connected by axially spaced brackets to form a reinforcement cage and which, as connecting rods, extend continuously through both individual blocks, whereby at least some protrude beyond the outer end faces of the individual blocks, and the use of track regulating portals is provided, on which a track grid is suspended and pre-adjusted before the fine adjustment is carried out by optical leveling on the top edge of the rail with actuation of the adjusting elements of the track regulating portals, and the previously loose Longitudinal reinforcements inserted in the concrete trough are raised and connected to the connecting rods and the projecting steel rod ends.
• a decisive advantage is the use of the track regulation portals. At intervals of two to four, preferably three sleepers, an entire track grate in lengths of up to 80 or possibly even 160 m can be relatively easily pre-adjusted.
• the installation method according to the invention is characterized by the use of two-block concrete sleepers with two reinforced individual blocks, with the reinforcement essentially parallel to the axis of the sleepers extending structural steel rods connected by axially spaced brackets to a reinforcement cage, which, as connecting rods, extend continuously through both individual blocks, at least some of which protrude beyond the outer end faces of the individual blocks, and wherein the longitudinal reinforcements previously inserted loosely in the concrete trough are raised and connected to the connecting rods and be connected to the outside protruding steel rod ends.
• the concrete trough can either be assembled from in-situ concrete or from prefabricated parts on a base, for example a concrete slab, or can also be produced using a slipform paver.
• a concrete trough is on a concrete slab 1 with the interposition of a seal 2 and a protective concrete layer 3 4 arranged in which the sleepers are to be held by casting.
• the concrete trough 4 is placed at intervals of preferably three sleepers, rail regulating portals 5, which each comprise the rails 7 between cross members 8 under two sleepers, which in turn are mounted on bearing blocks 9 and 10 so as to be vertically and transversely displaceable, some of which on the Attack the upper sides 11 and partly laterally on the outer surfaces 12 of the walls 13 of the concrete trough.
• the track regulating portals additionally have an intermediate bearing block 14 which additionally supports the cross member 8 in the middle, this intermediate bearing block 14 being supported on an assembly block 15 which is inserted between two sleepers in the concrete trough and which is later used after the adjustment of the Rails are also cast in.
• the installation takes place according to the invention in that first the sleepers are preassembled with the rails 7 to form a relatively long track grate and then an entire track grate is then adjusted and cast in the concrete trough on the upper edge of the rail.
• the special concrete sleepers 16 shown in the drawing which are designed as two-block concrete sleepers with two individual blocks 17 and 17 ', which are connected to one another by continuous parts of the reinforcement cages, structural steel rods 18 and 19.
• Three spaced structural steel rods 18 are preferably provided in the lower level and two spaced structural steel rods 19 are provided in the upper level, which are connected to the reinforcement cages within the individual blocks 17, 17 'by brackets (not shown).
• the lower structural steel rods 18 are preferably extended so far that they protrude outwards beyond the outer end faces 20 of the individual blocks.
• This special design of the two-block concrete sleepers enables a very simple connection of the sleepers with longitudinal reinforcements 21 and 22, which are also intended to hold the sleepers in the sealing compound 4, not shown, in the concrete trough 4.
• These longitudinal reinforcements 21 and 22, which are designed as structural steel rods in the exemplary embodiment shown, can simply be placed in the concrete trough 4 and, after the track grating has been adjusted, raised in sections precisely to the top edge of the rail with the aid of the track regulating portals 5 and with the reinforcement rods exposed as connecting rods between the individual blocks 17, 17 ' 18 are connected while the outer longitudinal reinforcements 22 are lifted from the bottom of the concrete trough and placed on the projecting ends 23 of the structural steel rods 18 and are in turn connected to these ends.
• the tedious threading of the longitudinal reinforcements 21, 22 through transverse holes in the concrete sleepers which is no longer feasible in the case of longer installation sections, is thus eliminated.
• the invention is not restricted to the exemplary embodiment shown.
