Definitions

  • the present invention concerns first, a procedure for a precisely aligned erection of a support beam (hereinafter, “support”) structure for a grade level travelway to accommodate a rail guided vehicle, in particular, a magnetically levitated railway vehicle, wherein the support possesses a top travelway plate with thereon attached guides for the said vehicle, this upper plate resting upon an under-structure, which has a base plate, this base plate being separated at a distance from the travelway plate by at least one intervening web.

  • the invention concerns second, a grade level travelway of a track guided vehicle, especially a magnetic railway vehicle, wherein the support possesses a top travelway-plate with thereon attached guides for the said vehicle, this upper plate resting upon an under-structure which has a base plate, this base plate being separated at a distance from the travelway plate by at least one intervening web.
  • DE 198 08 622 A1 discloses a generic travelway, which consists of precast concrete plates, on which are located lateral, functional planes for the guidance of a rail limited vehicle.
  • the precast concrete plate is affixed on the top surface of a support-structure by means of extending members, as well as being secured in that location by fastening devices.
  • the securement is executed in such a manner, that a free elongation is enabled for the of the concrete precast plates due to temperature expansion.
  • the support structure itself is set down on prepared ground at the selected location. Also, if it is correctly held, in the case of this cited invention, that where a grade level travelway is concerned, the thereto belonging precast top plate, which carries functional planes, must respond to temperature compensations.
  • the purpose of the present invention is, to create a grade level travelway and also make available a construction procedure for said travelway, wherein heat expansions, even at large temperature variations, are held within allowable tolerances.
  • the support structure is laid upon a base plate with the intervention of a web or webs situated on the said base plate.
  • the support is subjected to directive members (hereafter “guides”) on the base plate, so that in this location, a transverse motion of the support is largely excluded.
  • guides directive members
  • the support is caused to comply with its preselected space-curvature.
  • the intervening openings, which arise therefrom are subsequently filled with a grout between the base plate and/or the web, which advantageously allows a longitudinal displacement of the carrier on the base plate.
  • the support is force-fixed in position by the said grout with the under structure. While, in the case of short supports, preparations for a longitudinal displacement of the support is not necessary, conversely, where longer supports are involved, then the recommendation is advantageously directed toward compensation of the longitudinal extension. Exactly at which length of the support the tendency for longitudinal extension becomes necessary, depends on the conditions of the construction site and the requirements of the allowable tolerances during operating life.
  • the support has a web
  • the connection between the support and the base plate be in the area of the web.
  • the shaping of the web can serve as an element for the guidance of the support in a coaction with the guides on the base plate.
  • the support is essentially continuous in its setting on the base plate, then, a very simple manner of construction for the support is possible. Moreover, a particularly exact guidance of the support is obtained, by means of which tolerances can be held within a very narrow range.
  • the said spindles can be placed on the webs or at the connections.
  • the arrangement having the greatest advantage depends upon the shape of the support and the accessibility of the spindles.
  • the support at least at one position, especially in the area of the middle of the support, is immovably affixed to the base plate.
  • a rigid connection is made, which can serve as an base from which the longitudinal heat expansions of the support can extend themselves. If this fixed position is in the middle zone of the support, then the support experiences a relatively small heat expansion extending in both longitudinal directions from the centerpoint of the said fixed position.
  • the connection positions to the subsequently following supports are, thereby, little affected by the heat expansion.
  • a longitudinal displacement of the support can advantageously take place without a stressful reaction.
  • the support then slides on the said partition layer during such expansion as may be created by temperature changes or by applied loadings. This can occur, in keeping with the invention, without uncontrolled movements or contingent damages.
  • a plastic layer is inserted, which, when subjected to load, has the ability to yield.
  • This said layer in this protective manner, extends through the entire surface between the support underside and the thereunder located grout. A discrete diminishment of the load through the spindle is prevented.
  • an elastic grout material was used for the filling of the transverse guide openings, which were placed at an increased distance from the fixation and located between the support and the guides of the base plate.
  • the elastic grout is more or less compressed by the allowable longitudinal displacements of the support. Even in this case, damage to the support or to the base plate is avoided, and a desirable movement of the support is made possible.
  • the attachment elements placed in the upper chord were secured by being grouted in.
  • the pouring of the upper construction parts with the attachment parts was carried out in one work-step with the manufacture of the upper chord and this is done overhead.
  • the attachment elements can be welded or screwed to the attachment plate. This is possible, either with steel construction or with concrete construction and creates advantages, in the case of individual embodiments of the invention.
  • successive supports may be connected together, if the grout fill is elastic. If, contrarily, a grout fill is used, which is rigid and thus does not permit a depression of the support during passage of a vehicle, then the successive supports must remain uncoupled.
  • a generic travelway may be designed in such a manner, that the travelway comprises a support on the base plate having an intervening web attached to the support or to the base plate.
  • the support is limited as to movement in the transverse direction by guides on the base plate and/or on the web. On this account, a lateral displacement of the support is not possible.
  • the support is continuously carried on the base plate. This assures an exact guidance of the said support and the therewith related guidance of the vehicle.
  • the support possesses a web, which, in the construction assembly, extends itself downward from the said support, then, the possibility exists, that an alignment of the support with the base plate is advantageously realized. Moreover, the support itself receives, by the presence of a web, an additional stability, whereby the erection work and the operation are improved.
  • the base plate is a ground plate, on which the support stands, then in this case, a simple and rapid manufacture is possible.
  • the guides for the support consist of one or more blocks or intervening troughs.
  • the blocks which, for example, act as one with the webs of the support, provide the support with a guide in the longitudinal direction. The same occurs, if, in the base plate 1 a trough is furnished, in which the support can be seated. Even in this case, a known displacement of the support through shape-fitting is possible.
  • the support possesses a plurality of, or especially two webs, which are distanced one from the next in a transverse direction of the support, then an especially stable support has been created, which is also very easily guided.
  • the blocks of the base plate for example, can be placed between the two webs and thus a simple, shape-fitted longitudinal guidance for the support has been made available.
  • the support can be bound with the base plate, whereby a solid seating is achieved.
  • This solid seating can be made by a bolting with the base plate, or the base plate and the support, for example with the use of a connection reinforcement, can be united by concrete.
  • a rigid grout material is placed between the guidances and support, to create a shape fit connection and to lessen the longitudinal and transverse forces, then, in this case, during the erection of the support, adjustment can be made possible even in the transverse direction, and subsequently, during a pour, a rigid connection can be made, which makes possible a relative movement between the support and the base plate in the longitudinal direction of the support.
  • a partitioning layer intervenes.
  • the partitioning layer assures the mutual relative displacement of the base plate and the support means to one another.
  • the said weight-spring-system can likewise be brought about.
  • the depressing of two neighboring supports upon the roll-over of a vehicle must be compensated for by a coupling of the two supports in order to avoid an impact.
  • the support and/or the base plate possesses through running water fittings or run-off openings. Such construction makes it possible for inspection personnel and also for animals to cross the travelway and, in the case of rainwater or snow melt, dammed up water is avoided.
  • the base plate and/or the support is made specially as a precast concrete component, then a very exact fabrication and moreover a very rapid field installation of the travelway is made possible.

  • the ground plate 2 and the blocks 3 are made of concrete and are laid upon the ground.
  • the ground plate 2 can also be an otherwise intended construction member, such as, for example, a bridge or the bottom foundation of a tunnel section.
  • the blocks 3 place the guide elements for the support, which at a later time will be set upon the ground plate 2 .
  • the blocks 3 possess lateral sides 4 , which, under some circumstances, with the coaction of the of a grout material (to be described later) injected between the lateral sides 4 and the support, permit a movement of the support in the longitudinal direction x.
  • the blocks 3 possess in this embodiment example, moreover inner sides 5 and outer sides 6 . These sides 5 and 6 , which, in other, not presented embodiments are not unconditionally necessary, can receive grout applications in accord with the present embodiment. This grout application would be in reference to the support.
  • At least the sides, here 5 and 6 , placed more remotely from a solid bearing of the of the support are advantageously provided with an elastic grout material, so that heat expansions, which act in the x-direction of the support can be absorbed by the elasticity of this material resulting in freedom from damaging or improper stresses.
  • the actual travelway structure is placed thereupon on the upper surface 7 of the base plate 1 .
  • the guidance elements in the x-direction of the support in accord with another, not shown embodiment example, also can be formulated in a different manner.
  • blocks located midway also blocks can be provided which guide the support from the outside.
  • three blocks could be placed on the outer edge of the base plate 1 and externally guide the support.
  • the trough in this case, must be so dimensioned or set in grout filling, so that a movement of the support in the x-direction is permissible.

  • the blocks 3 form in connection, especially with the webs 12 , a longitudinal guide of the support 10 in the x-direction.
  • the support 10 is securely bound by means of a threaded bolt 15 with the base plate 1 .
  • the longitudinal expansion of the support 10 on this account then starts from this binding position at the said inner connection 14 , and extends simultaneously in directions to each end of the support in the location of the outer end connections 13 .
  • spindles 16 are provided.
  • the spindles 16 are to be found in the connections 13 and 14 of embodiment example of FIG. 2 .
  • These spindles 16 after the support 10 has been lowered on to the surface 7 of the base plate 1 , are more or less screwed out of the support 10 and thus perform the adjustment of the said support 10 to such a measurement as would be required for the travelway.
  • the intervening space caused thereby between the support 10 and the surface 7 of the base plate 1 is filled with a grout 20 .
  • This grout must be of such a nature, that it can compensate for longitudinal displacements of the support 10 on the surface 7 , which can result from stresses of heat expansion or loadings thereon.

  • the lateral grout material 22 is advantageously rigid upon cure and likewise is provided with a separative layer.
  • action can be taken similar to that of the grout application and the separative layer, in that a sliding of the support 10 in the x-direction relative to the base plate 1 can be carried out, without the danger of over-stress.
  • the lateral grout application act in such a way, that the support 10 , during its longitudinal displacement is exactly guided and thus no improper movement in the transverse direction y is made possible.
  • FIG. 3 shows a detailing in the area of an outer connection 13 .
  • Beneath the outer connection 13 the said rigid grout 20 has been applied.
  • hard grout 20 fills the intervening space between the upper surface 7 and the underside of the connection 13 , i.e., the web 12 .
  • the hard grout material 20 makes a secure connection in the vertical z-direction, so that the guidance of the traveling vehicle above the support 10 remains predominately unchanged in the z-direction.
  • an elastic inner grout application 23 is employed. Accordingly, the heat expansion in the x-direction is absorbed by the elastic grout 23 material and no opening is formed, that is, no undesirable stress is exercised between the outer connection 13 and the blocks 3 or the said elastic grout 23 . As an alternate, it is also possible to completely omit the grout 23 , if the formation of the blocks 3 or the connection 13 is of such a nature, that an intervening space between the block 3 and the connection 13 is allowable.
