Rescue vehicles drive with One tyre oil: the preilferlesied concrete: parts and with: thé: other tyre on a cable channel alongside the mil Since she prefabricated concreto parts arranged between the mils are extremely heavy they can only he moved by meelmmeaidiling tools. If repairs have to be carried out in the track then the removal of these prefabricated concrete parts is problematical as a result of the short blockage times. (8804) The object of the invention is therefore to provide a haliastless track for rail vehicles having a rescue path in which repairs can be carried out more easily. 1008ÏJ Tlvis is achieved by a haiiastless track of the type mentioned at thé beginning which; is tie fined by the features of claim 1.

[0008] The Invention is based on the knowledge that using machine lifting tools or other heavy apparatus when repairing a haliastless track having an escape path can he avoided if instead of using prefabricated concrete parts weighing several forts, smailer cover slabs can be used for the regions between and next to the rails, which (slabs) can be moved and removed manually or by simple non-mechanical lifting tools. The necessary repairs can thereby be carried out when required with simple means and in a short time without having to shut off the track section for a longer period of time, ÍÖ087J With thé baiiastiess track according to the invention the cover slabs have a substantially triangular basic shape: and two cover slabs are arranpd so that they form 0«e rectangle which covers the sleeper bay. The triangular basic shape of the cover slabs has proved; expedient in respect of their mounting. T wo cover slabs of this kind make up one rectangle which enables a subséquent repair or maintenance of the regions of the sleepers which are covered by same. {0888J it has provided particularly expedient if the sleeper bay In the case of the baiiastiess track according to the invention is covered by at least: two cover slabs. A small part désigíí Of the cover slabs can thereby be achieved which: leads to eorrespondlhgly small dintensious for the cover slabs which allow manual handling. lOÖÖfí As regards the mounting of the cover slabs it is preferred if the two cover slabs fisrmihg the rectangle«)·» arranged side by sic)« inJifei.kmgttadimd direction of the sleepers. PÖlbS .4 particularly secure hold is achieved if the cover slabs of the hallasd fess tracks according to the invention bave ribs of pedestals on their underside. Ribs andrer pedestals then serve as •reinforcement for the cover slab so that a hollow position in the sleeper bay is produced which facilitâtes the drainage of the upper side of the cover slabs and thus the escape path. piO] In order to improve the load distribution it) the case of the ballast less truck according to the invention a load-distributing intermediate layer, in particular a geotextile, bitumen hoard or elastomer layer, is arranged under the cover slabs, in particular under the ribs or pedestals; {00F|{ Securing the position can be achieved in the case of the hailastless track accordiug to the invention if the coyer dfetegrs IPkfefed .!$. m*M of screws Which are preferably screwed into screw dowels of the sleepers. pöflj In order to ensure belter access to the rails, it can be proposed for the bidiastiess track according to the: in vention that strlpdike slabs are arranged oo both sides of the ralik end these can be lifted and removed Whet): necessary, According: in a further development of the balíssüess track according to: the invention n can be proposed Fiat: -$0. piece with the cover slabs, As a result -of the small dimensions of the coyer slabs the t$$* can be exposed by removing the cover slabsiwhich: are formed In one piece with: the strip-like slabs,. The removed cover slabs can be placed ;d the sides so that the repaired mainlenance or repairworks can bo undertaken. pÖí4J in order to guarantee manual handling, with the hailastless track according 10 the mveutkm it is preferred if the weight of a cover slab is less than 230 kg, preferably less than 2Ö0 kg, |M|#| In of der to ensure the repaired strength and stability even when heavy rescue vehicles or firefighting vehfeles are driven over same, the cover slabs can be formed as precast reinforced concrete: parts. }ÖÖ16| Further advdhfaps attd details of the invention will be explained using an exemplary embodiment and with reference to the drawings.

These are twin-block sleepers whose grid supports B are cast into a track slab 18 in an installation position so that only the upper regions of the sleeper blocks P arc visible. {Oöiífl A sleeper hay which is formed: by two adjacent fails 3 and adjacent sleepers 2 arranged transversely thereto, is covered in the illustrated exemplary embodiment by two cover slabs % 7. The cover slabs 6, 7 arranged between the rais 3 have an at least approximately triangaiar basic shape, two cover Slabs ¢, 7 are tints arranged so that together they form a rectangle. It can be seen in Figure 1 that one pair of cover slabs 6, 7 jointly covers oae sleeper bay. It Is also apparent in Figure 1 that the shape of the cover slabs 6, 7 is not exactly tfianplar since the common edge does hot: ftm precisely through the corner points of the coyer slabs 6, 7.

The strip-like slabs 13 can be removed when repairs: have to be carried mu on the raiis, by way of example in the event of a rail breaking, in the illustrated exemplary embodiment the strip-like slabs id are formed in one piece with the cover slabs 7 so that the strip-Hke slabs IS can be removed when necessary by lifting and removing the cover slahs 6:, %.
