Definitions
- Threshold for arrangement on an essentially flat base, in particular intended for a slab track, preferably with recesses on the base side, which can be filled, at least in some areas, with a casting compound which adheres to or connects to the base and to the threshold, wherein the threshold can be adjusted in height by means of at least one spindle element which passes through a recess in the threshold and is arranged in a recess which runs through the threshold from its top to its underside,
- a track superstructure with rail sleepers and ballast shows particular technical limits, so that more and more use is made of the construction of a fixed carriageway with stable, rigid sleeper bearings.
- the threshold is placed like concrete sleepers on asphalt or concrete slabs or in appropriate troughs and then partially cast in a casting compound such as concrete or asphalt.
- a height adjustment can be carried out using spindles running within the threshold.
- the sleepers can have recesses on the sole side. This also results in a fixation against horizontal loads, especially when cornering (DE 34 29 413 AI).
- a reinforcement transverse reinforcement
- the sleepers are drilled through transversely to their longitudinal direction in order to then pull the reinforcement through. Then the threshold is cast, the casting compound must run above the reinforcement.
- the present invention is based on the problem of providing a threshold of the type mentioned at the outset which can be securely fastened to the base and can easily absorb transverse forces.
- a partial aspect of the invention also deduces simple installation or alignment both in the horizontal and in the vertical direction. Furthermore, the possibility should be given to remove the threshold from the base again with simple aids.
- the present invention is based on the problem of developing a sleeper, in particular a concrete sleeper intended for a slab track, in such a way that reinforcement of a plurality of successive sleepers, in particular that of a switch with reinforcement running in the longitudinal direction of a track, can be carried out in a simple manner without on the threshold a processing possibly leading to a weakening is necessary. If necessary, a threshold can also be exchanged without the reinforcement itself being destroyed.
- the problem is essentially solved in that the recess through which the spindle element passes comprises an upper and a lower section of different cross sections over a step, that at least abundantly extends in the lower section of a first sleeve of the spindle element, which is connected to an element which is supported on the support and from which a second sleeve, which extends at least in regions into the upper section and is rotatable to the first sleeve, extends into one the step-supported nut secured against rotation or an equivalent element engages.
- the threshold can consequently be raised or lowered by rotating the upper sleeve, so that vertical alignment is possible.
- This measure also ensures that the threshold can be easily removed even when the recesses are cast under; because when the second sleeve is turned and the threshold is raised, the threshold is automatically lifted off the surface like the road.
- the spindle element preferably comprises a plate which is supported on the base and which is arranged in a cavity of the threshold and is surrounded on the circumference by walls of the cavity. This measure ensures that potting material cannot get into the cavity when the threshold is poured under.
- the plate has a peripheral edge extending into the chamber, the height of the edge being at least equal to the maximum through the spindle element enabling stroke.
- the spindle plate preferably has a rectangular shape, so that consequently the walls delimiting the cavity also form a rectangular shape.
- the problem is also solved by a threshold in that successive sleepers have a threshold looking in the track direction Reinforcement in the form of reinforcing bars, such as round steels, can be connected, the reinforcement running below the threshold being held by fastening elements extending from the threshold.
- the reinforcement does not run inside the threshold, but below it, so that after completion of the threshold, bores or the like are not necessary. Due to the fact that the reinforcement runs on the sole side, pouring the threshold apart from the reinforcement is only necessary to the extent that the required fixing is ensured.
- the reinforcement is releasably connected to the fastening element, so that consequently an exchange of a threshold is possible without the reinforcement being damaged.
- the attachment is based on a plate element which can be supported on the base, by means of which the threshold to the base can be adjusted. With these measures, the reinforcement runs at a defined distance from the base.
- the plate element can have receptacles in the form of open bearings or closed brackets on its side facing the sleeper.
- the former offers the possibility that it is also possible to subsequently attach the reinforcement, such as round steel, to the plate element.
- This embodiment also has the advantage that the threshold can be replaced without having to remove the plate element and the reinforcement emanating from it.
- the fastening element starts from a screw or spindle element passing through the threshold and can be changed in distance from the sole of the threshold.
- the fastening element is anchored in the threshold and preferably starts from a reinforcing bar.
- the fastening element can have a sleeve-like or clamp-like receptacle for the reinforcement connecting successive sleepers.
- a U-shaped bracket with side leg sections running parallel or approximately parallel to the underside of the reinforcement preferably extends in a plane extending parallel to the underside of the sleeper as a fastening for the reinforcement, which are connected in a manner to the side leg sections can, as is known from reinforcement technology.
- the attachment can also be a U-shaped sheet metal element, the transverse leg of which extends along a nut of a screw connection, such as a push-through screw connection, which is arranged within the sleeper, and whose side legs penetrate the sleeper side and have openings for the reinforcement.
- a screw connection such as a push-through screw connection
- the push-through screw connection already present for fastening a ribbed plate or a sliding chair is used in order to serve as anchoring for fastening the reinforcement.
- a proprietary proposal for the height adjustment of a threshold with a rail section that can be fastened or supported on a fastening plate such as a ribbed plate or sliding chair provides that between the fastening plate and the threshold perpendicular to the longitudinal direction of the rail, adjustable first and second and at least in sections superposed wedge or ramp-shaped Steps run, which are sections of intermediate plate elements which preferably run between the fastening plate and the threshold.
- the first and second wedge-shaped or ramp-shaped steps can have a structuring that enables latching, such as sawtooth-shaped structuring, in their at least partially superimposed surfaces. With this measure it is only necessary to adjust the ramp or wedge-shaped steps against each other, whereby a height adjustment of the rail section is possible.
- wedge-shaped or ramp-shaped steps start from mutually adjustable intermediate plate elements
- fastening elements starting from the fastening plate such as push-through screw connections penetrate elongated holes in the direction of adjustment of the intermediate plate elements. This ensures that the mounting plate to the threshold can only be adjusted in height, but not in the plane.

- the lower section (46) is larger on average than the upper section (44), so that a step (48) runs between them.
- a sleeve (50) extends from the plate (40) and extends into the lower section (46) through the recess (42).
- a further sleeve (52) which is supported on the one hand on the lower sleeve (50) and on the other hand has an external thread onto which a nut (54) is screwed, which in the lower section (46) of the opening (42) is arranged, the step (48) resting on the nut (54) or on a disk provided on this. Furthermore, the nut (54) is secured against rotation, so that when the upper sleeve (52) ends, which ends at a distance from the top of the threshold (10), the latter is raised or lowered. In order to be able to rotate the sleeve (53), there are notches (56) arranged diametrically to one another.
- a bolt or screw (58) is present which passes through the upper sleeve (52) and with its external thread and cooperates with an internal thread embedded in the inner wall of the lower sleeve (50).

- Corresponding receptacles (64) and (66) are also provided for the reinforcements (38).
- a plate (68) required for this is not part of a spindle element, but is fixed in position with the aid of a bolt (70) relative to the concrete sleeper (10).
- the bolt (10) is preferably tightened to such an extent that the upper sides of the U-shaped elements (60) and (62) rest on the underside of the concrete sleeper (10).
- a plate (72) with an internal thread extends from the plate (68), into which the bolt (70) engages.
- This construction enables the plate (68) and thus the receptacles (64) and (66) to be detached from the concrete sleeper (10) if the latter is to be replaced or renewed.
- the spindle element (16) also serves as a fastening for a reinforcement (74) which, however, penetrates the lower sleeve (50) itself, so that additional receptacles are not required.
- transverse reinforcement (76) intended for concrete sleepers (10) and necessary for a solid carriageway can also be used. This is illustrated by FIGS. 6 and 7.
- a ribbed plate to the concrete sleeper (10)
- push-through fittings are used, one from the top of the ribbed plate or the Comprise sliding chair outgoing bolt (78) which passes through a non-rotating nut within the concrete sleeper (10).

- the fastenings (92), (94) form sleeve-like receptacles (98), (100) for the reinforcement and are placed on the round steels (18), (20) in the manner of clips.
- a corresponding fastening (94) can also be seen in FIG. 9 (left side).
- a transverse reinforcement (102) in a section (104) which is preferably made of plastic and which is part of the anti-rotation device of the nut (54) of the spindle arrangement (16).
- reinforcements (106) and (108) can also be placed on bearings (107) and (109) open towards the concrete sleeper (10) in order to tighten the plate (68) by means of the bolt (70) to clamp the reinforcements (106) and (108) between the underside of the concrete slab (10) and the U-shaped bearings (107) and (109).
- the threshold (110) which is preferably made of concrete, which in the exemplary embodiment consists of two sections (112) and (114) which are rigidly connected to one another via a plate (116) are.

- the threshold (110) has, in the region outside the spindle elements (120), (122) and (124), (126) described below and corresponding to FIGS. 3 and 4, ribs running perpendicular to the longitudinal direction of the threshold (110) , two of which are provided with the reference numbers (128) and (130) purely by way of example. If the threshold (110) is a concrete threshold, the ribs (128) and (130) are concreted on.
- the surfaces (132) and (134) of the ribs (128) and (130) facing the base (118) run in one plane, so that when the threshold (110) is straightened in the level of the base (1 18) from the threshold ( 110) a straightening machine can be added. This makes it possible to easily align the threshold (110) along the base (118).
- the ribs (128) and (130) delimit recesses (136) on the underside of the threshold (110) which are accessible from the long side. This results in the possibility that the recesses (138) can be cast under with a potting material such as concrete potting or asphalt potting in order to establish a connection between the threshold (110) and the roadway (118). The potting compound consequently brings about a positive connection between the threshold (110) and the roadway (118).
- the spindle elements (120), (122), (124) and (126) are in the threshold (110) penetrating recesses (138) are arranged such that they can be adjusted in height such that actuation of the spindle elements (120), (122), (124) and (126) in the manner described below causes the threshold (110) to be raised and possibly lowered again can.
- the recess (128) comprises a cylindrical upper section (140) and a cylindrical lower section (142).
- the lower section (142) is larger in diameter than the upper section (140), so that a step (144) is formed between them.
- a spindle plate (148) is adapted to the cavity (146) and, in the exemplary embodiment, has a rectangular geometry in order to form an anti-rotation device.
- the cross sections of the spindle plate (148) and the recess (146) are matched to one another.
- the spindle plate (148) can have a peripheral edge, not shown, which extends along the inner wall of the chamber (146).
- the chamber (146) is therefore delimited by a concrete sleeper (110) by a concrete (150) which is rectangular in plan view.
- a sleeve (152) extends from the spindle plate (148) and extends into the lower section (142) of the opening (144).
- Another sleeve (154) extends from the upper end area and can be rotated to the lower sleeve (152).
- the upper sleeve (154) has an external thread onto which a nut (162) is screwed, on which on the one hand the step (144) rests and which on the other hand is secured against rotation, so that by turning the upper sleeve (154) raising or lowering the Threshold (110) takes place.
- the upper sleeve (154) which ends at a distance from the upper side (156) of the threshold (110), has notches (158) which are arranged diametrically to one another and into which a tool can engage in order to rotate the sleeve (154).
- a securing bolt (160) is provided which passes through the upper sleeve (154) and has an external thread with one in the inner wall of the lower sleeve (152) internal thread interacts. After tightening, the head of the bolt (160) rests on the upper side (158) of the threshold (110) and at the same time closes the opening (138).
- the spindle elements (124) and (126) present in the area of the adjoining sleeper sections (112), (114) in FIG. 10 have the same structure with respect to the adjustment possibility of the sleeper (110) as the spindle elements (120) and ( 122).
- the rigid connection (116) extends from the spindle elements (124) and (126) in order to rigidly couple the sleeper sections (112) and (114) to one another.
- FIG. 13 and 14 show an alternative solution for adjusting the height of a rail section (164) which, in the exemplary embodiment, is fastened to a ribbed plate (166) without any restriction being intended to be made.
- the structuring provided in the surfaces (178) and (180) ensures that after adjusting the intermediate plates (172) and (174) against each other it is no longer possible to slide back.
