Definitions
- the invention relates to a threshold for supporting railroad tracks according to the preamble of claim 1.
- Such a threshold for receiving a measuring signal device under the rail is known from EP 0 468 397 AI, which is also provided as a concrete threshold and can be used in the measuring sensor to determine the vertical forces acting on the rails.
- EP 0 468 397 AI which is also provided as a concrete threshold and can be used in the measuring sensor to determine the vertical forces acting on the rails.
- pot-shaped or rectangular recesses are provided within the concrete sleeper, into which the transducers are flush with the upper sleeper side can be let in.
- recesses affect the transverse and longitudinal stability of the concrete sleepers in such a way that they are not suitable for higher speeds or a corresponding foundation would have to be provided.
- the invention is therefore based on the object of providing a standardized concrete sleeper which is suitable for fastening different measuring or special devices.
- the invention has the advantage that the anchored connecting plate in the area of the rail mounting enables measurement sensors, switching devices or other special devices to be attached without the strength of the concrete sleeper being impaired thereby.
- the sensors or special devices have a highly precise, flat support surface to which the fastening elements provided advantageously created a universal fastening option.
- the connecting plates are lowered relative to the remaining upper surface of the sleeper, so that the device can advantageously be mounted directly under the rails without the track position having to be raised or the sleeper having to be lowered further into the ballast bed.
- compensation plates can advantageously also be attached for height compensation, so that a special overall height of the special devices is not necessary, even compensation plates being provided can, according to which the threshold can also be used without special devices.
- Such sleepers can also be advantageously used over longer travel distances for the use of special devices for rail monitoring, environmental protection or measurement signal acquisition.
- a simple retrofitting of the route is advantageously possible, since the standardized concrete sleepers would only have to be exchanged for existing sleepers because of the same external dimensions.
- FIG. 1 a side view of a concrete sleeper half with a cutting area below the rail
- FIG. 2 a sectional view as a front view in the area of the rail mounting.
- Fig. 1 of the drawing the left part of a mirror-image half of the concrete sleeper is shown in side view, in which the one lowered connecting plate 2 is shown as a sectional view in the area of the rail mounting.
- this is a standardized concrete sleeper for rail travel routes that has the dimensions of a conventional travel route or turnout sleeper.
- the concrete sleeper shown is preferably provided for the attachment of force transducers, such as those used for weighing, for determining wheel runout and for detecting the running of trains.
- a turnout threshold is preferably used which has a higher threshold Contact surface and has a higher weight, and thus has a torsion-resistant and vibration-damping effect.
- Such a turnout threshold usually has a length of 2,600 mm, a height of 220 mm and a width of 300 mm, and a weight of approx. 390 kg.
- This concrete sleeper has a depression 11 of approximately 60 mm in the area of the mounting of the running rails on each side of the rail, in which a receiving element is provided which is designed as a connecting plate 2.
- connection plate 2 is arranged symmetrically to the middle of the rail 3 and thus allows the attachment of special devices such as force transducers, pressure transducers, speed transducers, rail switches, displacement transducers and other devices for environmental protection, in particular noise protection, as well as devices for rail monitoring directly under the rails.
- the connecting plate 2 can also be arranged lower or flush with the upper side 4 of the threshold.
- the depression 11 is in the longitudinal direction of the threshold 1 about 100 mm longer than the long side 5 of the connecting plate 2 and beveled upwards at the transverse edges 6.
- In the longitudinal direction of the concrete sleeper in each case in front of and behind the connecting plate 2, there is a drainage channel 7 through which rainwater and the like can flow into the ballast bed.
- the connecting plate 2 consists of a galvanized steel sheet of about 20 mm thick, which has fixed reinforcing elements 8 on its underside, which are anchored in the concrete and produce a firm connection to the concrete body 1.
- the thickness of the connection plate 2 depends primarily on the surface load and can also be made thicker or thinner in individual cases.
- the connection plate is rectangular and has fastening elements 9 in the corner areas which are designed as threaded bores.
- the fastening elements 9 can also be designed as stud bolts or as clamping elements.
- the connection plates 2 of each rail side are arranged horizontally and at the same height to the underside 10 of the sleeper.
- Connection plates 2 of this type can be concreted in with a height tolerance of less than 0.5 mm, so that a very flat and straight support surface for the special devices arranged thereon can be achieved, with which precise measurement tasks such as vehicle or axle weighing can also be realized. Thanks to the flat support surface, all special devices can be connected to the threshold that have a flat fastening part or can be arranged on a flat mounting plate. These mounting plates can then be easily screwed to the connection plate 2 or connected in some other way.
- compensating elements can also be provided on the flat connecting plate 2, which compensate for the height between the special devices and the underside of the rails or compensate for the entire height of the lowering 11, provided that no special devices are provided or should be retrofittable later.
- elastomers or other soft plastic materials can also be provided for the transition of stiffness or as a noise protection measure.
- the threshold additionally has a further third lowering 12 in the middle between the rails, in which a further third connection plate 13 is provided.
- This third lowering 12 serves primarily for fastening switch boxes, cable ducts and the like, as are necessary for the electrical connection of the special device and for the evaluation and transmission of electrical signals.
- FIG. 2 of the drawing shows a sectional view in the transverse plane AA of the threshold 1. 2 for the functional same threshold parts the same reference numerals as to Fig. 1 of the drawing.
- the concrete sleeper is also formed in the transverse direction symmetrically to a center line 15.
- the depression 11 in the area of the track support is limited by side concrete webs 16, between which the connecting plate 2 is cast in the concrete body 1.
- the lowering 11 can, however, also be provided over the entire transverse region if, for example, the special devices are intended to cover the entire threshold region in the transverse direction.
