Definitions

  • This invention relates to a rail element, in particular for subway, tramway and railway tracks.
  • the traditional railway or tramway superstructure generally comprises two rails supported by sleepers resting on ballast. In other cases it is also known to replace the sleepers and ballast with a single concrete bed.
  • the rails are grooved, and the entire superstructure is embedded in the roadway, with the rail iron surface at the same level as the road surface, and the connection between adjacent rails being made by joints or welding.
  • Total rail replacement involves on the one hand the problem of cost deriving from the material and the labour employed, and on the other hand problems of service interruption along the line, traffic problems and problems related to the excavation and renovation of the seat housing the rail.
  • the switch formed from a movable element known as the switch tongue which is interposed between two fixed elements known as stock rails, each consisting of a piece of rail which is suitably machined in the region below the head, is screwed to a support plate and is welded at its ends to the prolongations of the track rails.
  • the blade also consisting of a shaped rail element, is thinned at one end to be able to perfectly fit below the head of the adjacent stock rail.
  • DE-C 9443 discloses a discontinuous framework for connecting the rail to the sleeper.
  • the rail is fixed with respect to the framework through bolts or wedges.
  • US-A 1.260.148 relates to a U shaped structure whose webs are provided with shoulders to springly engage, through bolts the rail head of the rail within the cavity.
  • the rail element of the invention comprises substantially a monolithic iron body 2 of substantially H-shaped cross-section, closed lowerly to form a chamber 4 and provided externally with two appendices 6 for its fixing to support plates 7 and shaped substantially as the support flanges of traditional rails.
  • Said monolithic body 2 comprises two sidepieces 8 forming a seat 10 for housing the head 12 and the counterblade 14, constituting the wheel contact elements.
  • the head 12 and counterblade 14 are fixed to the box body 2 by bolts 16 inserted through slotted holes 21 of larger diameter, foreseen in the horizontal portion 24 of the body 2, and engaging in nuts 19 after interposing a bush 32 and a coil spring 23.
  • Gaskets 29 of self-adhesive rubber are interposed between the outer surface of the head and/or the blade and the inner surface of the box seat.
  • the interior of the chamber 4 can be filled with sound-absorbent material 20.
  • the monolithic body 2 is embedded in the roadway 33 and welded to the adjacent elements to create a continuous structure.
  • Each H-shaped element may be welded to plates 7 which have the same purpose as traditional sleepers.
  • the plates 7 rest on an insulating anti-vibration layer.
  • the rolling element (head 12 and counterblade 14) is then inserted into the seat 10 and is fixed to the base by the bolts 16.
  • the butt joint between adjacent elements is made at an angle of 45° to the cross-section.
  • the space between the two H-shaped elements can be provided with reinforcements and filled with concrete, or can be covered with a continuous plate 25 to provide a seat for the passage of cables and/or manifolds.
  • FIGS 4-6 illustrate a rail 33 prolonged by a switch 34 for directing a vehicle either onto the rail 35 or onto the rail 35'.
  • the switch 34 consists of a piece shaped upperly to form a seat 36 for housing the switch tongue 38, the two corresponding stock rails 40, 40' and the section bar 41 directly in contact with the heel 43 of the tongue 38.
  • the two stock rails 40, 40' and the section bar 41 are fixed to the base of the seat 36 by traditional bolts 42, whereas the switch tongue 38 is screwed to the box body in correspondence with the heel 43 and slides with its toe 45 on the base of said seat via an interposed plate (not shown on the drawings) of antiwear material.
  • the interior of the chamber 4 is filled with sound absorbent material and can also house traditional electrical resistance heater elements (not shown on the drawings) to ensure movement of the switch tongue even in the coldest weather.
  • the deviation element can also be used for cross-overs, in which case the movable elements are in the form of a single profiled piece comprising two crossing groves.

Claims (15)

  1. Schienenelement, insbesondere für U-Bahn-, Straßenbahn- und Eisenbahngleise, bestehend aus einer im wesentlichen H-förmigen, kontinuierlichen monolithischen Kastenkonstruktion (2), die in der Fahrbahn (33) einzubetten ist, so daß sich die Oberflächen der vertikalen Teile der H-förmigen Kastenkonstruktion auf derselben Höhe befinden wie die Straßenoberfläche, wobei der horizontale Teil (24) der Konstruktion mit den oberen vertikalen Teilen einen Sitz zum lösbaren Anschließen eines verschleißfähigen Radführungselements (12, 14, 38, 40, 40') definiert, wobei die Verbindung zwischen dem Führungselement und dem horizontalen Teil durch eine Mehrzahl von Bolzen (16) erhalten wird, die durch Schlitzlöcher (21) hindurchtreten, welche im horizontalen Teil (24) vorgesehen sind und einen Durchmesser haben, der größer als der Durchmesser der Bolzen ist, wobei die Bolzen (16) unter Zwischenlage einer Buchse (32) und einer Schraubenfeder (23) mit einer Mutter (19) in Eingriff stehen.
  2. Element nach Anspruch 1, dadurch gekennzeichnet, daß das Radführungselement aus einem Kopf (12) und einem Gegenblatt (14) besteht.
  3. Element nach Anspruch 1, dadurch gekennzeichnet, daß die Konstruktion (2) aus Eisenmaterial besteht und an ihrem unteren Ende zur Bildung einer Kammer (4) geschlossen ist.
  4. Element nach Anspruch 3, dadurch gekennzeichnet, daß die Kammer (4) mit schalldämmendem Material (20) gefüllt ist.
  5. Element nach Anspruch 4, dadurch gekennzeichnet, daß das Innere der Kammer (4) Verteiler für Leitungen und/oder Kabel aufnimmt.
