Definitions

  • the present invention relates to a central platform station on a railway or other line constructed in a viaduct.
  • Such viaducts generally consist of successive elements, of substantially identical section, constituted in particular by prefabricated concrete elements, and which are placed on a series of pillars implanted at suitable spacings.
  • these successive elements comprise a continuous upper slab, which forms a roadway, and on which, in the case of a railway line, the rails are placed, a lower slab, generally of smaller width, and connecting means connecting these slabs between them, preferably to form a box-shaped section.
  • Prestressing cables preferably placed inside the tubular structure, join the successive elements together.
  • the object of the present invention is to provide a central platform station, which uses the maximum of elements supplied by the prefabrication units of the viaduct line, and which is easy and inexpensive to assemble and make.
  • the structure according to the invention provides, in the center, in cross section of the station, a non-continuous zone in the longitudinal direction, which allows, easily, the establishment of stairs, elevators and other means of access to the platform, either at the ends thereof, or in hoppers arranged in the desired locations.
  • the upper and lower connecting pieces do not have to be in the same vertical plane. They can be offset, especially at the place of passage of stairs.
  • At least one upper connecting piece and one lower connecting piece are connected together to form a rigid frame, this frame being, here again, arranged in a vertical plane or, possibly, in an oblique plane.
  • the upper connecting piece carries at least one longitudinal beam on which the central platform rests, and preferably, there is a single longitudinal beam, and the central platform also rests on the elements by means of elements of support of suitable length. This gives a particularly light structure to the parts of the platform.
  • the platform is fairly small in width, it is preferred that it rest only on the elements.
  • the elements used for the construction of the station can be metallic elements, or mixed concrete-steel elements. However, these are usually, for cost reasons, prefabricated concrete tubular elements.
  • the edges of the upper and lower slabs have generally vertical and longitudinal surfaces, on which the end surfaces, also vertical and longitudinal, of the connecting pieces bear.
  • the mold does not include longitudinal vertical walls, it is easy to provide a temporary wall providing such surfaces at the desired locations, without it being necessary to provide a special mold for this case.
  • the connecting pieces are also made of concrete and prefabricated, either individually or by constituting a frame as indicated above, and they are connected to the elements by mated joints, that is to say made from a dry mortar, so as to ensure a good bond between these parts.
  • the figure shows two precast concrete elements 1, which are the same as those used for the viaduct. These elements are carried by pillars 2. They have a generally tubular shape, and include a slab upper 3, designed to constitute a roadway, and on which the rails are placed 4. A lower slab 5, of smaller width, is connected on each side to the upper slab by two oblique sails 6, also continuous. The outer surface of the sails 6, in the region where it joins the lower slab 5, has a longitudinal vertical part 7.
  • Prestressing cables 8 are used to increase the resistance of the elements 1, and to join them together. It will be observed that the usual length of the stations, which can reach 100 meters, requires the use of several elements 1 which succeed one another in the longitudinal direction, these elements being carried by a suitable number of pillars 2.
  • the bearing surfaces of the frame 9 are vertical-longitudinal, and a mated joint, that is to say say made from a dry mortar, is provided to effectively secure the frame 9 of the elements 1.
  • a lower prestressing cable 15, parallel to the cable 13 passes through the lower slab 5 of an element 1, the lower beam 11 of the frame 9, and the slab bottom of the other element 1, the anchor points 16 of this cable being provided on the outside of the elements 1.
  • the beams 10 carry a support beam 17, of inverted U section, continuous in the longitudinal direction, and which supports the elements 18 of the station platform.
  • These elements 18 are also prefabricated, they each comprise a horizontal slab 19, and a support element 20, which comes to rest on the upper slab 3 of an element 1.
  • each quay element rests at the same time on a slab 3, via the element 20, and on the beam with inverted U-section 17.
  • Two quay elements 18 are secured to each other and to the longitudinal beam 17 substantially in the longitudinal axial plane of the assembly.
  • the longitudinal beam 17 can optionally be omitted, the platform, which is then in one piece in cross section, rests only on the elements 1 by means of the support elements 20.
  • the oblique beams 12 of the frame 9 transmit the weight of the support beam 17 and of a part of the quay in the direction of the lower slabs 5. Due to the relatively low weight to be supported, the tightening obtained by the prestressing cables 13 and 15 , and the shear strength of these cables and the mated joints prevent a downward movement of the central part of the station.
  • staircase access stairs from the ground has not been shown in the figure. These stairs can be arranged either at the end of the quay, or in intermediate locations, anyway between two frames 9. In fact, beyond the ends of the station, the two elements 1 approach one another, frames 9 of smaller transverse dimensions being provided until connection to the normal structure of the viaduct.
