Definitions

  • the invention relates to a ballastless superstructure with prefabricated, rail-carrying concrete slabs, which have a greater extent in the upper longitudinal direction than transversely thereto.
  • Rail-bound traffic is of particular importance for the transport of goods as well as persons.
  • the track superstructure is of particular importance both for the higher speeds and for the increased ride comfort. Furthermore, it is necessary to reduce the maintenance times of the track superstructure as possible and to make it possible to repair malfunctions at short notice.
  • ballastless track superstructure In the different constructions different tasks have to be solved. Since the rails are to be interchangeable, detachable connections to the rails for the rails must be provided. These rails for the rails can be either a threshold grate or limited length concrete slabs.
  • the threshold grate may be placed in a concrete that has not yet set, and the rails must be precisely positioned to ensure an exact location of the rails.
  • the further possibility is to provide support plates with which the rails are also detachably connected.
  • semicircular recesses may for example be provided at the ends of the plates, which cooperate with corresponding circular cylinders which project perpendicularly from the ground. In reverse this can also be in the Underground circular cylinder be excluded, in which projecting approximately downwardly extending circular cylinder part.
  • Such cylindrical holding devices do not cause exact positioning, since displacements can take place along the cylindrical surfaces. In the event of breakage of an extension or of the cylinder which extends upwards from the ground, this end of the plate is without any fixation.
  • ballastless superstructure may not behave under load as a rigid body, but must elastically compress under load. Such compression should take place in the range of a few millimeters. In a ballast this elastic compression is achieved by a compression of the ballast bed, which leads to the discharge of the same expansion again. These processes cause wear of the ballast bed, at the same time the crushed grains are displaced below the thresholds from this area, so that regular maintenance, u. between a stopper of the ballast bed, especially under the thresholds are required.
  • the ballastless superstructure is in the Usually provided a separate construction element for this spring process. It can in this case an elastically deformable layer below the threshold grate or the support plates are arranged.
  • a ballastless superstructure which has a foundation plate, which is made in situ.
  • This foundation plate can also be formed trough-shaped.
  • a concrete mortar and possibly with Stahlarmtechnik a support plate, with which two rails are detachably connected.
  • For positional fixation of these concrete slabs of subsoil mortar can protrude into rectangular continuous recesses of the support plate.
  • at the respective ends of the support plate based on the upper structural longitudinal direction downwardly projecting projections are provided, which protrude into a recess of the foundation plate, wherein the gap is also filled by the underground mortar.
  • a rubber-elastic layer In the rectangular recesses may be provided between the penetrated in this underground mortar and the support plate, a rubber-elastic layer also. These rubber-elastic coatings correspond exactly to the outer dimensions of the support plates. For acoustic improvement of such a construction, the support plates may have a coating on their surfaces adjacent to the air. Although such a construction has proven itself, it is necessary to work with extraordinary accuracy and to avoid any damage to the layers in order to achieve the desired properties.
  • the present invention has the object to provide a ballastless superstructure, which has easy vor mattersertigende support plates made of concrete, which have a lower weight and can be arranged exactly fixed in position, which ensures a uniform compression of the support plate to the underground mortar and allows to build sound bridges between the Avoid substrate and the support plates as much as possible.
  • Another object of the invention is to prevent the penetration of the subsoil into the joint between the concrete slabs.
  • the ballastless superstructure according to the invention with prefabricated, rail-carrying concrete slabs which have a greater extent in the upper longitudinal direction than transversely thereto, with at least two polygonal recesses which extend from top to bottom and are open at the bottom, with an underground mortar lying on a substrate rests, extending at least into the two recesses and between the prefabricated concrete slabs and the subsoil mortar a substantially uniform thickness prefabricated rubber-elastic layer is disposed on the underside of the concrete slab, and the concrete slabs are arranged with their end faces at a distance from each other, consists essentially therein in that the rubber-elastic layer on the lower surface of the concrete support plate projects over the same along at least one side of its entire circumference and has a substantially uniform thickness, and between the end faces a floor for a concrete-free joint is formed by the protruding rubber-elastic layer.
  • the front side which is adjacent to another concrete support plate, in a simple and effective way, a seal of the gap, ie the joint between two concrete slabs are achieved, which without additional measures, penetration of the substrate mortar can be prevented in the joint, so that a free mobility of the concrete slabs, for example, due to the thermal expansion, is ensured.
  • a concrete-free joint is provided between the faces of the concrete slabs, which is optionally covered upwards, so the thermal expansion of the concrete slabs is particularly easy account, with surface water can be derived through the joint.
  • Is / are at the bottom of the joint of the supernatant region or the projecting portions of the rubber-elastic layer of two adjacent concrete slabs oriented down and possibly connected to the subsoil, so on the one hand, the gap between two plates can be sealed so far that the underground mortar not upwards penetrates.
  • a slipcase already in the production in the joints, with which the rubber-elastic layer (s) (s) is pressed down / are. After solidification of the underground mortar, the slip can be removed, wherein optionally the rubber-elastic (s) layer (s) is connected to the underground mortar / are. This results in a joint, which has due to the slipcase, a predestined width and is also particularly suitable for the discharge of surface water.
  • the layer on the underside of the concrete support plates allows the recesses to be accurately dimensioned, the layer has a recess which corresponds exactly to the recess in the concrete support plate so that any coatings on the side walls of the recesses can be applied particularly accurately and no gaps are created in which optionally the underground mortar can penetrate and thus a material bond between the same and the concrete slab is formed, whereby on the one hand sound bridges are caused and on the other hand, the required suspension properties are disturbed.
  • the concrete slab provided with a longitudinal and transverse flaccid reinforcement, which leaves the recesses, the concrete slab can be produced with very low weight, so that on the one hand a slight manipulation is given and on the other hand, the inertia of the superstructure is given in large concrete slabs, can be significantly reduced.
  • the walls of a recess are adhesively bonded to only one prefabricated layer of rubber-elastic material, gaps can also be avoided in the corner regions of the recesses.
  • Such a lining for the wall may have according to the corners of the recesses material dilutions, so that they can be easily glued to the respective corners.
  • the underground mortar and the concrete slab are at least partially arranged on a concrete slab or in a concrete slab provided on the ground, then it can be achieved that the forces are not transferred from the substrate mortar alone but also from the concrete slab to the substrate via the sidewalls of the slab, or an additional structural element for uniform power transmission on the ground is present.
  • the concrete trough or the concrete support plate on the substrate on substantially full-surface rubber-elastic bearings it may preferably in various constructions, such as bridges, tunnels u. Like. Particularly easy to avoid or weaken a transmission of vibration and thus due to sound.
  • the rubber-elastic bearings formed by at least two extending in the longitudinal direction of the superstructure profiles they can be easily installed, with an exact positioning of the tub can be realized with the simplest means.
  • a rubber-elastic layer is arranged between the concrete support plate and the side walls of the concrete trough, which is fastened to the concrete support plate, a direct action of force may indeed be effected, but due to the elastic layer a compensation is achieved, whereby further sound is passed on only subdued.
  • the downwardly facing surface of the rubber-elastic layer has a release agent, in particular wax, then concrete support plates can be exchanged particularly easily since there is no substance connection between the rubber-elastic layer and the underground mortar.
  • Fig. 1 two concrete support plates 1 are shown having from top to bottom through recesses 2 and through injection ports 3.
  • the support plates have a dimension of 2400 mm by 5160 mm. Typical dimensions are between 2000 mm to 2700 mm by 3000 mm to 7000 mm. Their thickness is between 140 mm and 250 mm, in the present case 160 mm.
  • the recesses 2 are formed rectangular, with the longer side of the rectangle is arranged parallel to the track Oberbauerstreckung and 900 mm, whereas the width extension is 600 mm.
  • the concrete slabs are, as shown particularly clearly in Fig. 2, over a substrate mortar 6 on a substrate, u. between the bottom of a concrete trough 7.
  • This concrete tub 7 in turn rests on rubber-elastic profiles 8 on leveled substrate 9.
  • the concrete tub and a concrete slab may be provided.
  • the profiles instead of the profiles be provided a continuous rubber-elastic layer.
  • the concrete bucket or the concrete slab can rest on the substrate via a large number of individual, discreet, rubber-elastic bearings. This can be achieved on the one hand, that the vibrations are transmitted only at discrete locations on the ground, which further has the possibility to avoid each other by different distances between the bearings that vibrations of a certain frequency are preferably passed to the ground.
  • the distance of the individual bearings to each set so that, for example, only with low intensity or not intended vibrations are preferably transmitted.
  • the concrete slabs 1 have a slack reinforcement 10, which terminates on the one hand in front of the recesses 2 and on the other hand in the upper longitudinal direction and transverse thereto.
  • the cover with concrete is at least 25 mm.
  • the concrete support plate has on its side facing the ground a prefabricated coating 11, which has a thickness of 30 mm and protrudes beyond the outer contours of the concrete support plate 1.
  • This layer is constructed with rubber particles with a mean size of 15 mm to 20 mm, which are connected by a polyurethane binder.
  • a plastic spray film is also suitable: Based on the width of the same projects at least 5 mm beyond the width of the concrete support plate, whereas in the rail longitudinal direction, the rubber-elastic coating 2.5 cm projects beyond the concrete support plate when the coating on each face of the concrete support plate dominates the same. If there is only one protrusion on three sides, a coating overhangs the joint. If, for their part, the concrete slabs do not rest in a sump, but only on another concrete slab or on the leveled ground above the subsoil mortar, it is sufficient that between two support plates follows a sealing of the joints.
  • This sealing of the joint can either be done by only provided on a support plate protruding rubber-elastic coating or be performed by the two end faces of the support plates protruding rubber-elastic coatings.
  • the underground mortar 6 also protrudes into the recesses 2 of the concrete support plate, wherein the side walls of the concrete support plate also has a rubber-elastic coating 12. In the underground mortar 6 in the recesses extends a reinforcement 13, so that the underground mortar with its projections and tensile stresses can absorb better.

  • dowels 15 are provided which cooperate with screws 16 which connect the rail 4 via clamping plates 17, base plate 18 and a rubber-elastic intermediate plate 19 releasably connected to the concrete support plate.
  • a thread 5 is made of plastic, which cooperates with the thread of a spindle 20.
  • This spindle 20 has an eyelet 21, which serves to facilitate operation of the spindle.
  • the coating 11 extends, as can be seen particularly clearly, beyond the contours of the concrete supporting plate 1 and adjoins the wall 28 of the concrete trough 7. Furthermore, a rubber-elastic layer 27 is attached to the concrete support plate and disposed between the wall 28 and the concrete support plate 1.
  • the underground mortar has a thickness d 1 of 100 mm (between 3 cm and 20 cm).
  • the rubber-elastic layer 11 is at its lower facing the concrete tub surface with a release agent, u. between wax, provided. As a result, it is easier to remove the repair case, ie the replacement of the concrete support plate.
