Dipl.-Ing. Egon Schubert, Vienna / (Austria; railway superstructure with cross sleepers

The invention relates to a railway superstructure with cross sleepers which, at both ends, are about a Third of the gauge protrude laterally over the rails.

For the railway superstructure, concrete cross sleepers from one block are already known, which the wooden sleepers are shaped similarly. There are also threshold gratings, in which two concrete blocks through steel or concrete parts - are connected to each other. r, quiet with such thresholds but have a low side shift resistance, which only depends on the friction in the ballast bed and the resistance of the sleeper head surface; they also have a relatively low stiffness in the vertical and horizontal direction, resulting only from the rails. These normal sleeper tracks therefore require relatively frequent work for leather production at high altitude and. side direction. There are no experiments with blocks that are integrated between the sleepers and anchored in the ground Brought success.

There are also '"! Quietly known with long concrete sleepers, which lie under the rails, relatively narrow and connected to each other at greater • intervals across the track are. These long sleepers can have two or more supports for one rail and a cross connection between them own, which can be articulated in the long sleepers. Long sleeper parts and these can also be used connecting Q, braces are provided that connected with tendons and the joints of which are sealed with cement mortar. Such tracks with long sleepers However, they have poor track guidance, because with a slight rotation of the long sleeper, the rail inclination increases changes. In addition, this railway superstructure requires different abstinence methods and different track-laying machines like a cross-sleeper superstructure.

In order to be able to absorb the large forces at the rail joint, the two adjacent to the joint are already in place Wooden sleepers by overplating with immovably connected sleeper pieces and by combining Support and clamping plates extending across the sleepers are connected to form a sleeper grid. This device However, it was also not able to prevail because the sleepers were weakened too much by the over-plating will.

Attempts have also been made to produce threshold gratings from a large number of parallel steel girders, which were connected at the outer ends with angle irons to provide greater resistance to side shifting to reach. The angle irons allow only a slight increase in rigidity and are thereby that they lie completely in the gravel, are used up prematurely and are difficult to control.

It is also known to arrange long sleeper pieces between cross sleepers and through the rail fastening serving plates and screws to unite to a grate. The junction between the long sleeper pieces and the cross sleeper is always in the area of the cross sleeper and it does not become more rigid Connection of the long sleeper pieces to the cross sleepers achieved, even if the long sleeper pieces in Freuzform are executed. Since the rail fastening was used to connect the parts, it is not prefabricated part that can be produced in series, but rather individual parts that are connected to one another at the installation site. Since such connections become loose immediately, this type of threshold grid could not prove itself.

Since -. "! Quietly for high driving speeds continuously must be in a good location, the cross or long sleepers have been replaced by concrete slabs on a trial basis or the rails are attached directly to a solid concrete body. The plates, also called support plates, extend both in the direction of the rails and across them. This track shape wiest due to the larger one Rigidity means less stress on the ballast bed and the subsoil and greater resistance the track position, but has major disadvantages: Such tracks are very expensive to produce because both the manufacture on site and the transport of the heavy individual pieces is difficult. Further the maintenance of such tracks is expensive because of the currently used working methods and track construction machine are not usable. Such plates cannot be stuffed uniformly and only with difficulty move.

The aim of the present invention is to create a railway superstructure of the type mentioned above, the that. The track has a higher resistance to lateral displacement and which is easy to transport and can be processed with conventional track construction machines.

■ has bare items.

This is achieved according to the invention in that each cross sleeper below the rails and / or in the area of the track axis on both sides in the direction of the rails and in the spaces between the sleepers Reaching rigid longitudinal beams, which preferably up to the longitudinal beam ends of the adjacent cross ties are sufficient. The side members rigidly connected to the cross sleepers increase the side resistance the sleepers essential and enable a mutual connection of the individual sleepers, .With the connection advantageously always lie in the threshold compartment.

Appropriately are according to a further feature

■ the invention connected at least two cross sleepers with their longitudinal beams to form a rigid sleeper grid, which forms a transportable unit. Such a threshold grate can be manufactured in the factory as a prefabricated part and can be connected to any length in the track with the neighboring sleeper gratings. With such cross-sleeper gratings the track is given greater rigidity in addition to the higher resistance to lateral displacement in a vertical and horizontal direction. Such threshold gratings are given such a length that they are in the track curve ■ can be laid like a polygon and that the degree of torsion in cant ramps by additional rail supports

documents can be reached. The ones remaining between the sleepers and the side members Gaps allow the use of the conventional work methods of sleeper track and of the existing track construction machines.

The cross ties and the side members advantageously consist of one piece and are made of, for example Eeton poured. There is the possibility of using pre-tensioned or post-tensioned steel inserts on the side members to be provided, whereby longitudinal cracks of the cross sleepers on the rail support are avoided at the same time.

It is also advantageous if the ends of the side members of adjacent transverse sleepers or sleeper gratings interlock in a form-fitting manner.

As already mentioned, the ends of the side members of adjacent cross sleepers or sleeper gratings be connected to each other. For this purpose, from the ends of the longitudinal members to be connected in each case, Oe-. in particular extensions of the prestressed or post-tensioned steel inserts protrude, which can be connected to one another via a turnbuckle. Another connection option is that of den one.der of the ends of the longitudinal members to be connected, a U-shaped organ protrudes into which one from the end engages the other longitudinal member protruding pin, the open side of the U-shaped member by a Cross bolt, e.g. a split pin, can be locked. Finally, however, it is also possible to connect the respective Ends of the side members conical, e.g. pyramidal
