Definitions

• the invention relates to a concrete sleeper with integrated into a threshold body, usable or inserted fasteners for fastening rails.
• the position of the rails can be regulated at conventional thresholds in the horizontal direction, transverse to the rails with the rail fastening in a range of about 8 mm.
• a greater adjustability would be desirable, so that for example caused by tolerances of the concrete sleeper tracking errors in the production of the fixed carriageway or could be compensated subsequently.
• solid lanes which must be expected by the operation of the rail vehicles or by changes in the position of the ground with horizontal displacements or deformations.
• a concrete sleeper which can be used for different gauges.
• the concrete sleeper In the area of the rail support area, the concrete sleeper has four fixing openings each, into which dowels can be screwed.
• the rail can be attached to two different ones
• Positions of the rail support area are attached by means of rail fasteners, in addition, a spacer is needed. In this way, a total of three different gauges can be realized. Since the rail can only be positioned at two different positions, the horizontal adjustability of this concrete sleeper is limited.
• a similar concrete sleeper is known from EP 0 377 765 A1. The concrete sleeper has four through holes for sleeper screws. The rail can be positioned above one of the two central passage openings, resulting in two different positions for each rail and thus three different gauges. However, further horizontal regulation is not possible.
• the invention is therefore based on the object to provide a concrete sleeper, which allows for improved horizontal regulation and in which a regulation of the rail is also possible later.
• the threshold body per concrete rail to be fastened rail has at least four openings for fasteners arranged in pairs left and right of the rail support area, wherein the two openings for fasteners of a pair in Longitudinal direction of the concrete sleeper are arranged offset.
• fastening elements encompasses dowels and / or sleeper screws, in particular for push-through fittings, or shoulders integrated into the concrete sleeper.
• the horizontal position of the rail can be adjusted almost infinitely in a wide range by each sleeper screw is optionally screwed into a dowel of a dowel pair, with both such a dowel pair is provided to the left and right of the rail.
• the angle guide plates arranged on the left and right of the rail have different widths. If a sleeper screw is offset on one side of the rail, the tie screw on the other side of the rail must be offset in the rail longitudinal direction in order to keep the distance between the two angle guide plates constant. If this is not possible or not desired, the changed position of the sleeper screw can also be compensated by using another angle guide plate. Accordingly, the horizontal position of the rail can be almost infinitely regulated by the choice of each matching angle guide plates in a large adjustment range.
• the angle guide plates arranged on the left and right of the rail may be offset relative to one another in the longitudinal direction of the rail.
• the concrete sleepers according to the invention has the advantage that the track width of the rails fastened to the concrete sleeper, that is to say the distance of the two rail heads measured on the inside, is constant, regardless of the position of the sleeper bolts.
• the invention relates to a method for regulating the position of rails, which are fastened by means integrated in a threshold body of a concrete sleeper, insertable or inserted fasteners.
• a concrete sleeper is used with a threshold body
• the pro to fixing rail has at least four openings for fastening elements, which are arranged in pairs left and right of the rail support area, wherein the two openings for fastening elements of a pair are arranged offset in the longitudinal direction of the concrete sleeper or are.
• dowels and / or sleeper screws in particular for push-through fittings, or shoulders integrated in the concrete sleeper can be used as fastening elements.
• each sleeper screw can be selectively inserted into one of two dowels, the mounting position of the rail on the concrete sleeper in its longitudinal direction during the production of the fixed carriageway or can be regulated later.
• the sleeper screws are released and at least one sleeper screw is screwed into another anchor.
• both sleeper screws can be screwed into other dowels.
• differently wide angled guide plates can be used left and right of the rail.
• the sleeper screws can be loosened and at least one sleeper screw can be screwed into another plug to compensate.

• the concrete sleeper 1 comprises a total of two rail support areas 2, which are interconnected by a central piece, not shown.
• the rail support areas 2 are symmetrical with respect to the center line of the concrete sleeper 1.
• the fasteners include mounting holes and dowels inserted therein into which sleeper screws are threaded.
• the rail support region 2 shown in Fig. 1 four mounting holes 3 are introduced, which are offset relative to the longitudinal direction of the concrete sleeper 1.
• a dowel 4 is inserted in each mounting hole 3.
• a rail 5 rests on an intermediate plate 6, below which a base plate 7 and an elastic intermediate plate 8 are located.

• Sleeper screws 13, 14 are screwed into the dowel 4 and press clamps 15, 16 against the angled guide plates 9, 10 and the rail 17 of the rail fifth
• the concrete sleeper 1 has four dowels 4 for the rail 5 to be fastened, which are arranged in pairs on the left or right side of the rail support region 2.
• the two dowels of a dowel pair are each offset in the longitudinal direction of the concrete sleeper 1.
• the position of the rail 5 in the horizontal direction can be regulated perpendicular to the rail longitudinal direction by the sleepers 13, 14 in one of the two dowels on the left side of the rail support area and in one of the two dowels on the right side of Rail support area 2 are used.
• the different attachment positions are compensated by appropriately selected angle guide plates 9, 10, it can be done by selecting suitable mating pairs of angled guide plates 9, 10, a regulation of the position of the rail 5 in the horizontal direction.
• the angle guide plates used 9, 10 may be different in width. It is essential that the free space between the angled guide plates 9, 10 remains substantially constant and corresponds to the width of the rail foot 17. In this way, the position of the rail can be regulated in practice in a range of about 8 to 40 mm, preferably in a range of about 15 to 30 mm.

• For attachment is ever a dowel 19, 20 of the left dowel pair and a dowel 21, 22 of the right dowel pair used. Accordingly, there are different possibilities for the attachment of a rail, which are shown in Figures 2 to 5.
• the two lower dowels 19, 21 are used for fastening the angled guide plates 9, 10 by means of sleeper screws. Since the angle guide plates 9, 10 have a different width, the rail is fixed outside the middle of the rail support area 2.
