Definitions

  • the present invention relates to a method for setting up the position of a precast concrete slab, in particular for a slab track for high-speed means of transport, the precast slab being supported by a substructure made of a hardenable casting compound and a base layer of the substrate, and the precast slab by several before the introduction of the casting compound
  • Vertical spindles are brought into a predetermined position as part of straightening aids, as well as a straightening aid for setting up finished part slabs, in particular for slab tracks with a vertical spindle for supporting the prefabricated slab on a base layer and a holder for connecting the vertical spindle to the finished slab as well as a finished slab, in particular for slab tracks, with a straightening aid which has a vertical spindle for supporting the finished part plate on a base layer and a holder for connecting the vertical spindle to the finished part plate.
  • the object of the present invention is therefore to avoid the disadvantages mentioned above and to create a method, a straightening aid and a corresponding finished part plate for this purpose.
  • the precast slab is supported by a substructure made of a hardenable casting compound and a base layer of the subsurface.
  • the prefabricated plate is brought into a predetermined position with several vertical spindles as part of straightening aids.
  • at least two of the vertical spindles are supported on the bearing layer on a bearing block which can be displaced in the longitudinal or transverse direction of the finished part plate. The mounting of the vertical spindles on the movable bearing block ensures that tensioning of the spindles is largely avoided, which means that the finished part plate can be positioned and set up very precisely.
  • the setup is done only by moving the Bearing block on which the end of the vertical spindle is supported.
  • the bearing block is firmly arranged on the base layer and, by moving the bearing point of the vertical spindle on the bearing block, brings about a targeted and predeterminable movement of the finished part plate. It is particularly advantageous if several bearing points are adjusted jointly, that is to say synchronously, in order to largely avoid tensioning here as well.
  • the vertical spindle is advantageously mounted in such a way that it can be pivoted on the pedestal during setup. This also prevents tensioning of the spindle in relation to the bearing block and enables the precast plate to be set up very precisely.
  • the finished part plate is roughly aligned by means of two vertical spindles arranged diagonally to one another on the finished part plate and is thereby supported on a third vertical spindle.
  • the weight of the plate is essentially supported on the two diagonal spindles.
  • the 'two spindles which are advantageously arranged diagonally on the plate corners, together with a third vertical spindle on which the plate can be supported, allow a statically defined support of the finished part plate, which means that there are no uncontrolled tensions and resulting reactions.
  • the three vertical spindles thus produce a three-point bearing, which is supported and secured after the rough straightening at the fourth corner of the plate by means of a further vertical spindle.
  • the finished part plate is straightened to the predetermined target size.
  • at least four vertical spindles are used, two of which are preferably arranged diagonally to one another on the finished part plate.
  • Two diagonally opposite straightening aids are advantageously operated jointly or synchronously, in particular with regard to the lateral arrangement of the plate, in order to to largely exclude conditions. Rotations of the plates which occur during rough or fine straightening and which can lead to longitudinal movements of the plate are compensated for by a longitudinal direction in which the bearing block can be displaced.
  • the straightening aid is arranged on the underside or the longitudinal outside of the finished part plate, the accessibility and usability of the straightening aid is improved.
  • the leveling aid can be completely removed after pouring the precast plate into the mold and used for another precast plate. Lost spindle sleeves are not used here.
  • the straightening aid or the fastening point of the straightening aid on the finished part plate is contaminated when the finished part plate is poured under, it is advantageously provided that the straightening aid or the fastening point are sealed off from the casting compound.
  • the straightening aid according to the invention is used to set up prefabricated board, in particular for slab tracks for high-speed rail traffic. It has a vertical spindle for supporting the finished part plate on a base layer and a holder for connecting the vertical spindle to the finished part plate.
  • the vertical spindle is supported on a bearing block which can be displaced in the longitudinal and / or transverse direction of the finished part plate. Due to the support of the vertical spindle on the sliding bearing block, hardly any stresses occur when the finished part plate is set up in the vertical spindle.
  • the contact point of the vertical spindle is positioned with the aid of the displacements in the longitudinal and / or transverse direction of the bearing block in such a way that the spindle is essentially only loaded vertically.
  • the adjustment of the position of the finished part plate is made possible by adjusting the bearing block very precisely, without constraints and jerks. Adjustments, for example, of more than ⁇ 12 mm transversely to the finished part plate are thus easily possible.
  • the vertical spindle is connected to the bearing block via a ball joint.
  • the connection can advantageously be made by anchoring, which prevents the vertical spindle from lifting off the bearing block.
  • the inclination differences between the plate and the support can be compensated for by the ball joint. Usually a movement tolerance of up to 20% is sufficient, but depending on the construction, a higher movement can also be allowed.
  • the ball joint allows movements in the transverse and longitudinal direction of the plate, so that unevenness in the plate support can be compensated for without constraint.
  • the bearing block has a guide carriage which can be displaced transversely to the finished part plate and on which the vertical spindle is arranged, the displacement of the bearing block in the transverse direction can be carried out very easily.
  • the finished part plate is set up by moving the guide carriage in relation to the base of the bearing block, which lies firmly on the base layer.
  • a horizontal spindle is assigned to move the guide carriage. With the help of this horizontal spindle, the support of the vertical spindle can be moved without force and without jerking and therefore very precisely.
  • the precast plate When setting up the precast plate, the precast plate may move longitudinally.
  • the bearing block is mounted displaceably on the base layer in the longitudinal direction of the finished part plate.
  • a particularly simple one Execution of this displaceability in the longitudinal direction is achieved in that the guide carriage is arranged on a support profile.
  • the guide carriage which is responsible in particular for the transverse movement of the finished part plate, thus moves on the bearing profile, which in turn is firmly attached to the base layer.
  • the relative movement between the support profile and the cross guide slide in turn compensates for tension in the vertical spindle.
  • the support profile allows, for example, a movement in the longitudinal direction of approximately ⁇ 10 mm and advantageously encompasses the guide carriage in the lateral direction, so that there is stabilization.
  • the finished part plate is equipped with several straightening aids.
  • the straightening aids arranged on the corners of the finished part plate for setting up the finished part plate are advantageously supported on the displaceable bearing block just described.
  • the further straightening aids which are arranged, for example, in the longitudinal direction of the finished part plate, approximately in the middle of the finished part plate, do not necessarily require the movable bearing block, since they are only used to support the finished part plate against deflection after the finished part plate has been set up.

  • the leveling aid can be removed from the finished plate after the precast plate has been poured under it and used completely for setting up another precast plate. Lost spindle sleeves as in the prior art are not required.
  • the claw ensures that the loads from the vertical spindle are always diverted exclusively by pressure into the ground.
