Definitions

  • the invention relates to guideway supports for magnetic tracks and the like.
  • Track-bound transport systems to which the stators of linear motors can be attached and which absorb all loads, in particular as a result of carrying, guiding, driving, braking and depositing the vehicles.
  • Magnetic tracks of the above type reach very high speeds of up to 500 km / h or more.
  • the magnetic railway vehicles travel on guideway girders, which in turn rest on supports and / or foundations erected on the building ground (ground).
  • the guideway girders must ensure that all loads occurring during driving operation can be absorbed and reliably transferred to the substructures (supports and foundations) and the foundation.
  • the guideway supports must follow the specified route in terms of route and gradient (this is the target line of the road) very precisely. This applies particularly to the positional accuracy of the functional surfaces and -components that are required on the guideway girders for driving.
  • the previously known guideway girders consist of steel girders or prestressed concrete girders.
  • the three above-mentioned functional components are three individual parts which have to be connected to one another and to the steel guideway supports by means of screws or corresponding, preferably adjustable fastening means in an extremely precise position.
  • the three above-mentioned functional components are an integral part of the welded steel guideway girders.
  • the known guideway girders in concrete construction consist of prestressed concrete girders into which steel anchor bodies are concreted as construction parts for the positionally correct connection (fastening) of the stators. After the prestressed concrete beams have been manufactured, the steel side guide rails are attached in a subsequent separate operation (cf. also DE-A-27 44 367).
  • the steel girder design with the screwed-on functional components requires very high expenditures for production and corrosion protection.
  • the fully welded steel girder version is cheaper in terms of corrosion protection, but even here the required high positional accuracy of the functional components can only be achieved with cost-intensive measures during production, as is also the case with the prestressed concrete girders.
  • the thickness tolerances of the steel side guide rails that occur during their manufacture in the rolling mill are a major reason for the measures required in the manufacture of the guideway girders. These thickness tolerances are already of the same order of magnitude as is permitted for the finished guideway construction.
  • the invention has for its object to provide a guideway girder which has favorable properties for the load-bearing and the deformation behavior, which is maintenance-free as long as possible, and whose target shape can be achieved with high accuracy in a cost-effective manufacturing process.
  • the solution to this problem consists in a guideway girder of the type mentioned in the introduction that the guideway girder consists of steel structures which, at least in the area of the upper girders of the guideway girder with reinforced concrete or prestressed concrete, are shear-resistant to a composite girder by means of a compound. are connected, and that the side guide rails are welded to the steel structures of the guideway girder.
  • the shear-resistant connection of the steel structures with reinforced concrete or prestressed concrete creates a composite girder that has a higher rigidity than steel girders, which reduces the deformation due to traffic loads.
  • the deformation due to different temperature distribution in the guideway girder e.g. due to solar radiation
  • the welding of the side guide rails to the steel structures of the girder represents a secure connection with a long service life.
  • the steel structures of the guideway girder can be prefabricated individually and used as formwork or formwork aids for concreting.
  • the rolling tolerances of the steel side guide rails can thereby be eliminated and the target shape of the guideway girder can be reliably achieved with little effort if adjustable devices with side stops are used.
  • composite girders are lighter in weight than prestressed concrete girders. This results in advantages for production, for equipping the guideway girders with stators (linear motor) and for the assembly process on the construction site, since the capacities of the means of transport and the lifting devices can be designed accordingly smaller.
  • steel needles according to claim 2 instead of reinforcing bars or structural steel mesh mats enables a simple and safe method for increasing the tensile strength of the concrete, particularly in the area of difficult to access areas. Places that are difficult to access are e.g. for the side guide rails and sliding levels (on the top flange) and in the area of the bottom flange.
  • the desired shape of the guideway girder can be achieved by subsequent tightening if it has not been achieved sufficiently enough during the manufacturing process.
  • prefabricated concrete parts according to claim 4 has the advantage that they can be produced completely separately from the rest of the support structure and that after a temporary storage the shortening due to the shrinkage of the concrete has already taken place and has ended. Without storage time, the shortening must be taken into account as the planned deformation of the guideway girder.
  • the maximum transport and lifting weights can also be reduced with precast concrete elements, which is important when considering the long distances to be built.
  • continuous girders By connecting two or more guideway girders, the length and weight of which are limited, so-called continuous girders can be created at the construction site, which are supported in the longitudinal direction by more than two support points (supports, foundations). With continuous beams, the deformations due to traffic loads and due to different temperature distribution are significantly less than with single span beams (with only 2 supports). It has been shown that the connection of the concrete parts to achieve the continuous effect is not necessary and the connection of the steel parts of the adjoining guideway girders by welding or screwing is sufficient. Continuous girders with a large length are thus realized, but the weight and the length of the to the construction site transporting single carriers remain below the economically justifiable limits for transport and assembly on the construction site today.
  • a composite guideway beam is shown in cross section.
  • the concrete slab 1 on the upper flange 10 and the concrete body 1 on the lower flange 11 are connected to the steel structure 3 in a shear-resistant manner with the aid of composite means 4.
  • the steel structure 3 arranged below the upper chord 10 consists of two lateral longitudinal plates which are welded to transverse bulkheads 7, so that they form a type of trough together with the lower chord. This creates a very stable composite support structure.
  • the side guide rails 5 are firmly welded to the two steel structures 3 of the upper chord 10. This ensures exact compliance with the gauge in a particularly permanent connection.
  • the tendons 2 can be used to increase the load capacity, to reduce the deflection due to creeping of the concrete and subsequent correction of the carrier shape can be used.
  • Steel sheets serve as sliding planes 6, the spacers 8 of which simultaneously serve as a compound.
  • FIG. 2 shows a composite girder construction for the guideway, which differs from the construction shown in FIG. 1 in the area of the functional components (side guide rail 5, sliding plane 6) and the lower flange 11.
  • a sheet metal is welded to the upper end of the side guide rails 5 perpendicular to them, which serves for load transfer and at the same time contains the two sliding planes 6.
  • This constructive training is cheaper in terms of durability than the solution shown in Fig. 1.
  • the lower flange 11 is made of sheet steel and has no concrete body. The support should be built with a corresponding length increase during production. By the time of commissioning, this increase is largely reduced by the shrinkage of the concrete 1 in the upper chord 10.
  • a lower flange 11 without concrete can also be used in the embodiment according to FIG. 1.
  • Fig. 3 illustrates the advantages that are achieved in the manufacture of the composite support structure according to the invention.
  • the manufacture takes place in a position rotated by 180 ° and in devices 9 which - which is not shown in the drawing - can be adjusted or selected with regard to their dimensions such that the desired shape of the composite construction can be specified with them.
  • the side guide rails 5 are part of two separate steel structures 3, these can be on the side Stops of the devices 9 are fixed. This eliminates the unavoidable thickness tolerances of the side guide rails 5 from the rolling process, so that compliance with the track width defined by the distance between the two side guide rails 5 is ensured.
  • the adjustable devices 9 and the two steel structures 3 serve as formwork.
  • the further, trough-like steel construction 3 with transverse bulkheads 7 made of steel is manufactured in separate devices.
  • This trough-like steel structure 3 can be welded to the two steel structures 3 connected to the concrete slab 1 with the side guide rails 5 without difficulty, since only the usual manufacturing and assembly tolerances of the steel structure have to be observed.
  • the two side guide rails 5 are welded to a continuous cover plate 14, to which the composite means 4 are also fastened, preferably welded.
  • the elimination of the thickness tolerances of the side guide rails 5, as can be seen immediately in FIG. 4, is ensured by the position of the weld seams 15 and their design.
  • the concrete body 1 can then be concreted using the customary construction methods, the steel structure 3 serving in part as formwork. 4, the functional components or surfaces (side guide rails 5 and sliding planes 6) are an integral part of a continuous (one-piece) steel structure 3. This also offers considerable advantages for the durability of the guideway girders, in view of the fact that the girders when later driving operations are exposed to all weather influences for decades.
