Definitions

• the invention relates to a track, the rails of which are each borne by a dimensionally stable support plate arranged under these rails, which track further fills the space between the rails, inner roadway plates and outer roadway plates adjoining the rails on the outside are provided which roadway plates form a rail-like traffic area, the support plate extending out over the full width of the outer roadway plates and the outer roadway plates resting on the support plate.
• the support plate creates a stable base for the rails of the track over long periods of time, so that such tracks require little maintenance or maintenance work with regard to the rails and their positioning.
• the rail-like traffic area formed by the carriageway slabs leads to the formation of level crossings and also generally to the formation of roads and paths in the track area, as is the case, for example, in the area of manufacturing and warehouse facilities, but also in the case of roads led in the area of settlements, Meaning too.
• the track designed according to the invention of the type mentioned at the outset is characterized in that the outer carriageway slabs are held on the support slab against lateral displacement by means of shaped engagement formed with undercuts.
• the rail track built up on the support plate and the inner and outer carriageway plates forming the rail-like traffic area are combined into a compact whole, which gives advantages in terms of the required construction and positioning work and in terms of long-term behavior in operation.
• the support plate consists of a composite material, preferably concrete being considered. This can be a cement-bound concrete, with or without the addition of synthetic resin, or also a synthetic resin-bound concrete. Reinforcement can also be provided. Support plates can also be provided with a reinforcing frame. The same applies to the pavement slabs.
• the roadway plates preferably have a rough surface on their side forming the traffic flat.
• An embodiment of the track designed according to the invention which can be realized with a very small number of components and which gives very good stability, is characterized in that the support plate has upwardly projecting, undercut edge strips on its lateral edges, on which the outer edge the outer carriageway slabs are supported.
• the track is characterized by the fact that the track has outer carriageway plates, each of which has at least one longitudinal strip or nose projecting downwards, which extends into a corresponding recess on the top the support plate located underneath is inserted, the downwardly projecting strip or nose being undercut on its side facing the outer edge of the relevant carriageway plate and the depression provided on the upper side of the associated support plate for receiving this strip or nose on its adjacent outer edge of the relevant one Support plate facing side is undercut opposite to the undercut of this bar or nose.
• a particularly good hold of the outer carriageway slabs on the support slab is achieved in this way.
• a preferred embodiment of the track is characterized in that the two rails of the track each rest on the support plate by means of elastic intermediate layers, and that the rails keep track of the rail-side through the inner track plates, which exert an outward force on the rails Edge of the outer carriageway slabs are pressed.
• This design results in particularly simple conditions with regard to the work required for the construction of the track, adequate stability of the rails being achievable for moderate travel speeds on the rail track, as is generally the case in the area of manufacturing and storage facilities, and also makes it possible if necessary a simple modification or repair of parts of the rail track and / or the rail-like traffic areas.
• the support plates have groove-like depressions at the locations provided for supporting the rails, the bottom of which has a slope corresponding to the inclination of the rails of the track with respect to the top surface of the respective support plate.
• Very simple conditions with regard to the installation of the inner carriageway slabs can be achieved by an embodiment which is characterized in that the track has inner carriageway slabs which are each formed from at least two strip-shaped parts lying next to one another in the transverse direction of the track, which lie against one another with their mutually facing longitudinal edges and which with their longitudinal edges facing the rails rest elastically on the rails.
• This embodiment makes it possible to achieve very good positioning and a very stable hold of the rails in a simple manner even with rails which are each laterally displaceable on the support plate.
• the assembly work it is particularly advantageous if one provides that the strip-shaped parts forming the inner roadway plates are joined together in a hinge-like manner.
• a structurally simple embodiment which is favorable in terms of achieving a good hold of the carriageway slabs is characterized in that the track Has roadway plates that are screwed to the support plates.
• a variant of this, which enables very rapid assembly, is characterized in that the track has carriageway plates, which are detachably fixed to the supporting plates against lifting off with rods projecting from the supporting plates.
• support plates With regard to the design of the support plates, a reduction in weight and an associated easier handling during installation and when correcting the bedding can be achieved, whereby, based on the amount of material used, very good stability can be obtained if it is provided that support plates are provided, which recesses and / or have openings so that these support plates are frame-like or skeleton-like.
