  • the object of the present invention is therefore a pavement slab device, which is suitable for vertical, longitudinal and lateral forces from dynamic To cushion the effects sufficiently without the support of the track slab device to deform or destroy, with sufficient flexibility against expansions occurring due to temperature changes or Shrinkage is given.
  • an elevated pavement slab device especially for rail mounting and support, comprising at least one prefabricated panel spanning the base, with individual support elements at the ends the precast slab are provided, which are along or across the road extend, and serving to support the support elements are provided troughs rest on a solid surface or foundation and in which the support elements are recorded and attached or stored.
  • the support elements are preferably provided with an elastic covering at their ends Mistake.
  • the elastic sheathing is, for example, an elastomer, e.g. Hard rubber. This creates an elastic joint that is suitable to withstand vertical forces, Longitudinal and lateral forces from dynamic effects are strong absorbed without the risk of destroying the support. Further there is the advantage that later foundations can be set at any time by lifting the slabs and potting of the cavities in the area of the web are balanced can be. The plates can be lifted and replaced without being destroyed or be installed in another way. So the system creates one special flexibility in use.
  • Elastic water channels are preferably provided between adjacent plates. These gullies serve the troughs and through the support elements and to keep the troughs formed as dry between the Plates of liquid absorbed are conveniently drained off. In the support area no water and frost damage can occur. Bridge the gullies the free distance between adjacent precast slabs. The gullies are particularly preferably recorded in opposite slots in adjacent plates. This means that they can simply be pushed across the panels.
  • the plates have projections at their ends have and adjacent panels are arranged so that a joint through a or both cantilevers are covered.
  • This can also be a suitable one Water supply must be ensured so that water and frost damage are effective be avoided.
  • the support elements are preferably connected to the tubs by a compound.
  • This compound is preferably grout.
  • This grout that can be used in the tubs for the fixed support of the support elements can be quickly made binding, so about 2 hours after completion commissioning of the elevated carriageway slab device is possible.
  • Bars are preferably provided for additional support of the precast slab, which are arranged below the plate and in the longitudinal directions to the road and support or brace the plate. So that is a bend of the Precast panels, especially when driving with heavy locks effectively reduced.
  • the beams are provided with the support elements or with additional ones Cross bars connected or stored on it. This configuration is in particular preferred for larger plate dimensions, especially plate lengths.
  • Trapezoidal support elements are preferably provided where there is compensation an elevation (for example in curves or arches) is required.
  • an elevation for example in curves or arches.
  • the elastic sheathing with a sound-absorbing material is preferred Mistake. This allows the excitation and schail radiation of the plate reduce effectively.
  • the support elements are preferably tapered downwards, namely in width and / or depth, preferably tapered.
  • Holes are preferably provided in the plate above the tub, which lead to Serve an adjustment spindle. With this spindle the plate can be compared lift the foundation.
  • the prefabricated panel is continuous in the area of the support elements Has holes that extend vertically through the plate and the support element extend. This enables the supply of a press fluid, that subsequently serves to lift the road slab.
  • elastic spacers are arranged below the trough are. These spacers are designed to be elastic after underfilling the tub to avoid damaging the tub or the support.
  • the trough preferably has openings below for the discharge of compound the tub.
  • the flat support is on after the tub is installed the subsurface or foundation.
  • Each tray preferably takes two supporting elements of adjacent prefabricated panels on. This creates an effective bond between adjacent panels. Further the number of tubs is minimized, so that the economy increases.
  • Steel brackets are preferably fastened in the middle region of the tub.
  • the grouting mortar entered into the tub is made by the steel bracket attached that he can not come out of the tub.
  • Drainage openings are preferred in the side walls of the tub educated. This will destroy the tub and support by water or frost effectively avoided.
  • the support element provided with an elastic covering preferably rests in or on a steel structure.
  • the support or sheathing through a steel structure has the advantage that a foundation Raising the pavement of the precast slab and inserting additional ones Steel plates can be corrected.
  • the reinforcement of the slab is preferably prestressed in the transverse and longitudinal directions. This results in greater strength or stiffening of the plate.
  • the tub preferably has a rain cover made of plastic or rubber on the side. This prevents water from entering the tub.
  • the trough is particularly preferably integrated in the foundation.
  • the tub can be designed as a tub-like foundation head. Also this will further reduce costs.
  • the foundation can be as Prefabricated part with integrated tub can be installed.

  • FIGS. 1-3 show a raised pavement slab device according to FIG shown the invention. This pavement slab device is essential Part of precast panels 1.
  • the prefabricated panels 1 are not supported over a large area in this construction, as is customary on the road, but supported on individual foundations.
  • the distance between the supports depends on the size of the loads and according to the distances in the axis order of the traffic loads.
  • each of the slab bases can be spaced 1.80 m apart then no more than one axle load is eliminated.
  • Strips Holes (strips) for transverse laying are used for laying tiles in open terrain Strip foundations excavated. On bridges and in tunnels are common no separate foundations required.
  • the plates 1 are preferably manufactured as prefabricated concrete parts. Therefore can they are also made in winter. They have plate-shaped support elements 3 with which the plates 1 are supported downwards and laterally.
  • the support elements 3 can be designed as columns, webs or cuboids. They protrude Troughs 2, which are attached to the foundations. Instead of separate The foundations can already be tub-like on their top be trained.
  • the plate-shaped support elements are one embodiment, as shown in Figures 1-3, arranged transversely to the road. This means, that they the precast plate 1 in the direction of the front and rear in Support cross direction. In another embodiment, shown in FIG. 5 the support elements run longitudinally to the carriageway and support the precast slab sideways.
  • tubs 2 are directly on the deck or attached to the tunnel floor by underpouring.
  • Troughs 2 can also be manufactured as prefabricated concrete parts. you will be then laid using elastic spacers 14 and then with casting compound 5 so that they are vertical and horizontal Loads into the foundations on the bridge deck or on the tunnel floor can remove.
  • the plates 1 with their support elements 3 laid so that the support elements 3 protrude into the tubs 2. Are the plates 1 finally laid and aligned, so the remaining cavities the tub 2 filled with grout. So that the plates 1 on their Support elements 3 stored so that they all positions, including side impact stable can forward downward, laterally and in the longitudinal direction.
  • the parts of the support elements 3, which are in the grout, are previously covered with an elastic sheath 6 or durable with elastic Mats glued.
  • additional Retaining bracket 10 e.g. be created as reinforcement, or in the interior protrude into the tub 2.
  • prefabricated panels of different lengths e.g. 1.20; 1.80; 3.60 m (multiple of the base spacing of 0.60 m or 0.65 m) are produced, which are then combined so that approximately the length of the building is achieved. Slightly, the plates 1 can still with their Troughs are moved in the longitudinal direction against each other, so that all plates 1 lie on the structure.
  • a drain is therefore used for drainage 8 made of sheet metal or rubber as protection against water penetration and frost damage on grout and storage in the joint between the panels 1 e.g. in Halfen rails 9 attached.
  • the elastic sheathing of the support elements 3 in the area of the grout 4 allows the plate 1 to be stored with a defined elasticity. That is for even load distribution.
  • shocks, vibrations and other vibrations are deliberately cushioned and off the surface be kept away from the bridge or tunnel.
  • the grout in the tubs 2 for the support of the support elements 3rd can be made so quickly binding that about 2 hours after completion the new structure can be opened to traffic.
  • the storage of the plates 1 and 2 tubs can be seen from the outside be checked at any time.
  • the new, also lateral cavities are created when the panels are lifted because the Support elements 3 conical - tapered downwards - are formed.
  • the conical Support elements 3 allow subsequent lifting of the plate.
  • the lifting the plate 1 can be adjusted by means of adjusting spindles 11 in holes provided therefor or done by pressing.
  • the outer walls of the Troughs are formed too high and thus as an adjustment support 12 for Spindles 11 are used.
  • the foundations can therefore be set without Restriction of train traffic through the use of hydraulic special presses between plate 1 and tub 2 can be compensated for relatively quickly by the slabs, including the track, are raised and locked in the correct position become.
  • the restored plate position can then - as described above - by pressing the voids created by the lifting around the support element 3 or the web are solidified around the compression channels 15.
  • plates 1 can be replaced if they are from any Reasons e.g. have been destroyed by an accident.
  • Replacement plates of identical construction and dimensions are manufactured, the But support elements 3 are somewhat shorter than those in the first laid panels.
  • the cavities created during the new installation can be removed again fill with potting compound 4 so that the laying process of new panels less Effort required than the first time when the tubs 2 are not damaged are.
  • the dimensioning of the plate 1 does not need a fluctuating quality of the Soil to be adapted.
  • the plates 1 always get the same Thickness and reinforcement. This makes them particularly suitable for precast concepts.
  • the previous multi-layer base layer structure can be used omitted, since a transverse one is used to accommodate the elevated superstructure monolithic strip foundation without additional formwork for storage the tub 2 is sufficient. If necessary, the foundation head can be used as Tub 2 are formed so that a separate tub part is omitted. On strip foundation placed in this way until the depth of frost on grown soil is likely to be more resistant to subsidence and flooding be as a poured base.
  • the slabs can be placed on piles come to rest with tub-like pile heads, or the Pile head is designed to receive the tub 2. Soil exchange and Earth dams are then not required.
  • the raised plate 1 makes the use of herbicides unnecessary, because it is not stored on the earth, so that the groundwater is protected.
  • the system for the rehabilitation of the Oberau on bridges is ideal. Because part of the ballast lying on the bridge can be between the troughs below remain on the plate as ballast. This ballast prevents the Bridge structures due to the relatively large for the own weight of the bridge Bulge pre-tension by creeping. Also reduce the cost of that Dispose of the entire ballast.
