In a trackway made of concrete slabs (1) with rails (2) for guiding rail-bound vehicles such as railways or tramways, the rails (2) are arranged countersunk in in each case one groove in the slab (1) and are guided with an elastic sleeve (3). The rails (2) have a rail head (7), a rail web (8) and a rail foot (9), wherein a minimum width (B) of the groove is larger than the maximum width (b) of the rail foot (9). The concrete slabs (1) are prefabricated components which have positioning elements and connecting elements at their end sides and are permanently connected to one another. The rails (2) are longer than the slab (1) and are pressed into the elastic sleeve (3) of a plurality of slabs (1). In a method for manufacturing a trackway made of concrete slabs (1) with rails (2), the slab (1) is manufactured with the groove and is then installed in the trackway. Finally, the rails (2) are pressed into the elastic sleeve (3) of a plurality of successive slabs (1).

A girder of a guideway for a track-bound vehicle, particularly a magnetic levitation system, comprises a concrete slab (2) laterally protruding from the girder (1). At both lateral ends of the slab (2), stators (15, 16) are mounted on the underside of the slab (2), lateral guide rails (12) are mounted on the lateral surfaces of the slab (2), and gliding strips (8) are mounted on the top side of the slab (2) for driving and guiding the vehicle. Curable, particularly concrete positionally correct bearing surfaces (5, 6, 7) for the lateral guide rails (12) and/or for the stators (15, 16) and/or for the gliding strips (8) are formed on the girder (1), and the lateral guide rails (12) and/or the stators (15, 16) and/or the gliding strips (8) are detachably mounted, particularly bolted, onto the bearing surfaces (5, 6, 7) provided therefor.

The present invention relates to a vehicle for a magnetic levitation track having a coach body (1) and a propulsion and supporting device (4) as well as at least one levitation frame (2) fastened on the coach body (1) and the propulsion and supporting device (4). The levitation frame (2) can be deflected transversely to the longitudinal axis of the propulsion and supporting device (4) and a spring suspension system (12, 14, 20, 21) is arranged between the levitation frame (2) and propulsion and supporting device (4). The levitation frame (2) has a traverse (13) and a carrier (17) which are connected to each other in an articulated fashion.

The invention relates to a method for the production of a tower (1) of a wind power plant, wherein at least one tubular tower section (2) is produced from annular precast concrete parts (5) having two horizontal contact surfaces (21), which are arranged on top of one another. After casting, the annular precast concrete parts (5) are set up in a processing station (27) in the precast plant and the two horizontal contact surfaces (21) of the precast concrete parts (5) are processed in a fixture in a planparallel, material-removing manner. A tower (1) of a wind power plant comprises at least one tubular tower section (2) of annular precast concrete parts (5) having two horizontal contact surfaces (21), which are arranged on top of one another. Both horizontal contact surfaces (21) of the precast concrete parts (5) are reworked in a planparallel, material-removing manner with a parallelism deviation and a flatness deviation of few tenths of a millimeter, preferably less than 0.2 mm.

The invention relates to a solid trackway (1) for rail vehicles having a substantially continuous bedding of the rails (2) on a concrete slab (3), wherein the rail (2) is supported with the foot thereof on an elastic intermediate layer (7). The solid trackway (1) further comprises a side guide piece (8) supporting and guiding the rail (2) in the horizontal direction. The rail (2) is mounted on the concrete slab (3) at discrete mounting points (9) by means of a mounting means (12). Only the elastic intermediate layer (7) is disposed between the rail (2) and the concrete slab (3).
摘要:
The invention relates to a method for constructing a rigid track for high-speed rail traffic. According to said method, the inventive rigid track is either constructed from precast concrete components (7) arranged on a track bed structure (2,4;16), an intermediate region between the concrete components (7) and the track bed structure (2,4;16) being filled in with a solidifying filling material (8) in order to fix the position of the concrete components (7), or from cast-in-situ concrete or a combination of concrete components (7) and cast-in-situ concrete on the track bed structure (2,4;16). The inventive method is characterised in that the track bed structure (2,4;16) is created from an existing ballast bed (2), the ballast being at least partially compacted. The invention also relates to a corresponding communication track of a rigid track.

The invention relates to a method for correcting the position of a slab construction, especially a solid carriageway for high-speed vehicles, consisting of precast concrete slabs (1). The precast slabs (1) are supported by a substructure made from a hardenable underpoured material (4) and a supporting layer (5) on the base. In order to correct the position of at least one precast slab (1), the precast slab (1) is at least partially detached from the substructure, especially from the under poured material (4) and/or the supporting layer (5), whereupon it is finely aligned and then underpoured once more with said material (4). A separating device (20,21) is arranged on a precast concrete slab (1) which is to be detached on a successive precast concrete slab in a device provided with one such separating device in order to detach at least one part of a concrete slab (1) pertaining to a solid carriageway for high speed vehicles from the substructure thereof, especially when the position is corrected.
摘要:
A method for the production of a precise pre-cast concrete piece, in particular in the form of a sleeper or plate for a fixed track for railed vehicles is disclosed. According to the invention, said method is characterised in that the pre-cast concrete piece is first produced as a blank in a form and then worked, at least in the functionally relevant regions, to the given dimensions.
