Abstract
Trackway for land traffic vehicles, preferably for magnetic levitation tracks, with pre-assembled trackway beams arranged on substructures produced by in situ concrete construction or pre-assembled construction. The trackway beams include one or more hollow, reinforced longitudinal pre-stressed concrete beams and trackway panels, which extend transversely to the pavement and protrude on both sides beyond the pre-stressed concrete beams. The trackway panels are separate components from the concrete beams. The concrete beams are constructed as pre-stressed concrete supporting pipes produced by molding concrete by centrifugal action and have flat upper supporting shoulders for supporting the trackway panels.
Claims41
A trackway for land traffic vehicles, comprising:
- at least one hollow, reinforced longitudinal pre-stressed concrete beam having flat upper supporting shoulders, said at least one concrete beam being constructed as a pre-stressed concrete supporting pipe by molding concrete by centrifugal action;
- and
- trackway panels separable from said at least one concrete beam and supported on said shoulders of said at least one concrete beam, said trackway panels defining a track support surface, each of said trackway panels being arranged to transversely overlie said at least one concrete beam and project over both lateral edges of said at least one concrete beam.
A mold for producing a pre-stressed concrete supporting pipe having outwardly projecting reinforcing ribs for a trackway, comprising:
- a mold plate having the external shape of the pre-stressed concrete supporting pipe;
- pre-stressing steel rods distributed asymmetrically in an interior defined by said mold plate;
- and
- supporting ribs distributed on said mold plate asymmetrically about an axis of rotation of said mold plate so that, in conjunction with the asymmetric distribution of said pre-stressing steel rods, an imbalance resulting from the increased proportion of concrete in a region of the reinforcing ribs is compensated for.
A trackway for land traffic vehicles, comprising:
- at least one hollow, reinforced pre-stressed concrete beam having a cylindrical shape and defining a cylindrical cavity, said at least one concrete beam having supporting shoulders extending upward and laterally from outer arcuate surfaces;
- and
- trackway panels separable from said at least one concrete beam and supported on said shoulders of said at least one concrete beam, said trackway panels defining a track support surface,
- each of said trackway panels being arranged to transversely overlie said at least one concrete beam and project over both lateral edges of said at least one concrete beam.
A method for constructing a trackway for vehicles, comprising the steps of:
- forming pre-stressed concrete supporting beams having outwardly projecting support shoulders at an upper region by creating a mold in the shape of the beams, inserting concrete into the mold and spinning the mold to thereby form the beams by centrifugal action;
- forming trackway panels separately from the beams and which define a track support surface;
- and
- attaching the trackway panels to the support shoulders of the beams.
