摘要:
The invention relates to a method for the production of a precise concrete prefabricated part, especially the form of a sleeper or a plate (1) for a fixed track for rail-guided vehicles, wherein the concrete prefabricated part undergoes grinding to the predetermined size at functionally relevant points by means of a grooved roller (21). The device therefor is a grinding machine (15) with a grooved roller (21) which is used to grind the concrete prefabricated part at functionally relevant points to a predetermined size. The grooved roller (21) consists of a grinding material, especially silicon carbide.

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 invention relates to rigid track consisting of concrete, in particular of pre-cast concrete components, comprising a slab (1) with traversing fixing elements (4), or a plurality of fixing elements arranged thereon, of rails (3) for track-borne vehicles. The inventive rigid track is characterised in that a pre-cast concrete component constitutes a protuberance (5) that is positioned on the slab (1), parallel to at least one rail (3) and located on at least one side of the rail (3), to act as a guard and a guide for the vehicle during a derailment.

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.

The invention relates to a tower (1) comprising a lower tubular tower section (2) made of concrete, an upper tubular tower section (3) made of steel and an adapter piece (7) for connecting the two tower sections (2, 3). The adapter piece (7) consists of an annular concrete element (8) and a steel element (9), the steel element (9) containing at least one annular flange (9a) that covers preferably entirely a surface of the concrete element (8), said surface being at the top in the installed state. The steel element (9) is directly cast together with the concrete element (8), wherein the annular flange (9a) is completely underpoured, essentially without air inclusions. In a method for producing a tower (1) comprising an adapter piece (7), a steel element (9) having an annular flange (9a) is placed head down into an annular formwork in order to produce said adapter piece (7). A concrete material is then introduced into the formwork in order to produce an annular concrete element (8) of the adapter piece (7), whereby the concrete material is directly applied onto the subsequent bottom side of the flange (9a).

An offshore station (1), in particular an offshore wind power station, comprises a floatable foundation (2) that can be sunk by flooding a hollow chamber, and a superstructure (6) on which functional units (7, 8) of the station (1) are arranged. The foundation (2) includes a bottom plate (3), a base (4) which is disposed on the bottom plate (3) and projects from the water surface (12) in the sunk state of the foundation (2) and on which the superstructure (6) can be mounted, and a floodable floating device (5) which surrounds the base (4) in the shape of a ring. In a method for building an offshore station (1), in particular an offshore wind power station, a floatable foundation (2) is prefabricated in a harbor zone, is towed to a mounting location after being prefabricated and is sunk, whereupon the station (1) is completed with a superstructure (6) and functional units (7, 8) of the station at the mounting location. In the harbor zone, a bottom plate (3) of the foundation (2) is concreted, a base (4) of the superstructure (6) preferably made of prefabricated concrete parts (15) is mounted on the bottom plate (3), and a floodable floating device (5) which surrounds the base (4) in the shape of a ring is mounted on the bottom plate (3) and/or the base (4) once the base (4) has been mounted.

A mount for a magnetic levitation railway has functional elements (9, 10, 11) for guidance of a vehicle for the magnetic levitation railway, on both sides along its longitudinal extent. The mount is in the form of a bending mount (2) of a switch arrangement and can be moved elastically from a first position of a first driving direction of the vehicle to at least one second position of a further driving direction of the vehicle. The bending mount (2) is produced essentially from concrete.

The invention relates to a fixed running track (1) on a bridge structure, in which a concrete slab (3) is positioned on a bridge girder (2) to support a rail (6) for a rail vehicle. The concrete slab (3) forms a continuous strip that extends over at least two bridge girders (2). A continuous profiled concrete layer (7) is situated between the concrete slab (3) and the bridge girder (2). A running layer (10) is situated between the profiled concrete layer (7) and the bridge girder (2) and the profiled concrete layer (7) is permanently fixed to the concrete slab (3) of the fixed running track (1).
