Definitions

• the present invention relates to a method for positioning a carrier for a ground-level travel path of a track-bound vehicle, in particular a magnetic levitation train, the carrier having a guideway plate with guide elements arranged thereon for the vehicle, the carrier being arranged on a base carrier which has a base plate and the base plate is kept at a distance from the guideway plate by at least one web, and a ground-level guideway of a track-bound vehicle, in particular a magnetic levitation train with a carrier, the carrier having a guideway plate with guide elements arranged thereon for the vehicle, the carrier on a base carrier, which has a base plate is arranged and the base plate is held at a distance from the guideway plate by at least one web.
• a generic route which consists of a precast concrete slab, on the two lateral edges of which functional levels for guiding a track-bound vehicle are arranged.
• the precast concrete slab is arranged by means of spacers on the top of a beam and fastened there with holding devices. The fastening is carried out in such a way that free expansion of the temperature of the precast concrete slab is possible.
• the carrier itself is placed on the ground of the site.
• the carrier is placed on the base carrier with the interposition of the web arranged on the carrier or the base carrier.
• the carrier is guided by guides of the base carrier, so that transverse movement of the carrier is largely excluded here.
• the support is brought into its predetermined spatial curve by means of spindles supported on the base support or the web.
• the resulting space between the base support and / or the web and / or support is then filled with an under-molding compound which advantageously allows a longitudinal displacement of the support on the base support.
• This method according to the invention ensures that the carrier is subject to a temperature expansion only in a very defined manner. While a transverse movement is largely excluded, a longitudinal movement of the carrier in the advantageous embodiment is only allowed along the guide elements.
• the support is non-positively through the base with the underlying surface or structure fixed. While in the case of short supports a longitudinal displaceability of the support is usually not necessary, it has proven to be particularly advantageous for longer supports to compensate for the longitudinal expansion.
• the length of the girder that the longitudinal displacement is required depends on the structural conditions and the requirements for the permissible tolerances in operation.
• the carrier has a web
• the design of the web can already act as an element for guiding the carrier in interaction with the guides of the basic carrier.
• the carrier is mounted essentially continuously on the basic carrier, then a very simple construction, especially of the carrier, is possible. In addition, a particularly precise guidance of the carrier is obtained, with which the tolerances can be maintained even in a very narrow range.

• the fixed point is arranged in the longitudinal direction of the carrier in the region of the center of the carrier, the carrier experiences a relatively low thermal expansion on both sides of the fixed bearing. As a result, the connection points to the subsequent beams are little burdened by the thermal expansions.
• a rigid potting material is used between the guides and the carrier, the longitudinal and transverse forces that occur are derived through the positive connection between the guides and the carrier or potting material.
• the carrier is guided very closely and permits no or only slight movements in the transverse direction. This enables exact positioning of the carrier or of the attachments arranged on the upper chord. The vehicle can thus be guided very precisely.
• a separating layer is arranged between the base support and the support, in particular between the casting compound and the support, a longitudinal displacement of the support without tension is advantageously brought about.
• the carrier slides on the separating layer in its expansions, which are caused by changes in temperature or applied loads, without uncontrolled movements or even damage occurring.
• a plastic plate is advantageously arranged between the spindle and the base support, which can yield somewhat under load. As a result, it supports the entire area between the underside of the beam and the casting. A discrete load transfer via the spindle is prevented.
• an elastic casting material is used to fill in transverse joints between the support and the guide of the base support, which are spaced further apart from the fixation.
• the elastic potting material is more or less compressed by the permissible longitudinal displacement of the carrier. This also prevents damage to the carrier or the base carrier and enables a targeted movement of the carrier.
• the attachments are cast into the top chord.
• the casting of the Add-on parts with the upper belt are carried out in one step in particular with the production of the upper belt and this is done overhead.
• the attachments can be welded or screwed to the top chord. This is possible both in the case of a steel structure and in the case of a concrete structure of the carrier and creates advantages in individual embodiments of the invention.
• the support is cast in with the load applied, it is ensured that the support and thus the attachments have the required position, in particular when the load is applied.
• successive carriers are coupled to one another along the travel path when the casting compound is elastic. If, on the other hand, an under-molding compound is used which is rigid and therefore does not permit a change in the height of the carrier when the vehicle is crossed, the carriers can also follow one another uncoupled.
• a generic travel path is designed such that the travel path from a carrier is arranged on the basic carrier with the interposition of the web arranged on the carrier or the basic carrier.
• the carrier is guided in the transverse direction by guides of the base carrier and / or the web.
• a lateral evasion of the carrier is not possible.
