Definitions
- the object of the invention is a prefabricated, in particular slack, reinforced support plate, which is constructed with concrete, of a ballastless superstructure for rail-bound traffic, for at least two rails.
- ballastless superstructure for rail-bound traffic is becoming more and more important, the longer the tunnels are, since the ballastless superstructure requires less height than the ballast superstructure, and furthermore the higher the speeds of the trains and the greater the train sequence , since longer intervals for the repair are possible, and at the same time shorter times for the repair occur.
- ballastless superstructure Various systems of the ballastless superstructure are known, it being important how the forces from the rails are introduced into the superstructure. For example, it is known to countersink rails together with concrete sleepers in a not yet hardened in-situ concrete, with a very complex, since exact adjustment, u. between both the horizontal and vertical directions.
- Support plate is supported in its four corner areas on spindles on an underbody.
- the support plate has a soundproofing material on its underside, u. between a polyester polyurethane foam. A flowable, solidifying mass is introduced between this layer and the substrate.
- the soundproofing layer also allows the support plate to deflect.
- a ballastless superstructure like a ballast superstructure, is not a rigid structure, but rather the deflection of the rails be made possible.
- the rails rest directly or indirectly on elements of the superstructure via a rubber-elastic layer, and on the other hand, the elements that introduce the forces from the rails into the ground also spring up on the ground.
- this suspension is achieved by mutually supporting the gravel grains. This flexibility can be so great that, for example, concrete sleepers break, especially in the middle area. Support plates are also used for the ballastless superstructure, and after relieving the pressure, they strive to return to the original position.
- the invention is based on a prior art, as given by EP 1 039 030 AI.
- AT 238 239 B describes a railroad-level crossing with a plate without recesses.
- Another object of the present invention is forces as high as possible from the support plate to the ground, u. between. In the longitudinal direction of the rail and transversely thereto, to be able to be transferred, a long service life of the support plate should be guaranteed at the same time. Due to the long service life of the support plate, however, it must not be prevented that it resiliently remains on the ground, since otherwise rails and wheels, in particular wheel rims, can break.
- the dimensioning of the support plate ensures that, on the one hand, an exact alignment of the support plates is possible when laying, and on the other hand, that the recesses, into which parts manufactured in situ then engage on the sub-surface when the support plate is positioned, allow precise positioning to be maintained over the long term. Due to the specific dimensioning of the recesses, u. between the fact that these have a greater extension than normal in the longitudinal direction of the rail, it is taken into account that In particular, due to the sinus movement of the wheels, a load transversely to the longitudinal direction of the rail can be greater than in the longitudinal direction of the rail.
- the openings which are open all the way down, make it easier to fill an intermediate space between the support plate and the base, while at the same time the body for fixing the support plate can be manufactured particularly easily.
- the rubber-elastic coating on the underside of the support plate enables the necessary compression.
- the two mentioned recesses represent a particularly advantageous solution for the transmission of the forces from the support plate into the subsurface, they weaken the support plate in the transverse and longitudinal direction of the rail. Such a weakening can be avoided or reduced in the longitudinal direction if the upper and lower reinforcement each have at least two longitudinal reinforcements with reinforcing bars arranged at both ends in the longitudinal direction of the support plate, which corresponds to the longitudinal direction of the rails, which reinforcements are arranged at both ends are connected to the upper or lower frame.
- a further introduction of force can be achieved by the upper and lower reinforcement on both sides of the mung arranged transverse reinforcements with reinforcing bars, which are connected to the upper or lower frame.
- An additional reinforcement can be achieved in that the upper and lower reinforcement has longitudinal and transverse reinforcements with reinforcing bars arranged on both sides of the recesses, which are shorter than those which are connected to the upper and lower frame and to the frame connected longitudinal reinforcements are connected.
- the upper reinforcement has shorter longitudinal reinforcements with reinforcing bars than those that are connected to the frame and with the transverse reinforcements with reinforcing bars to the upper or lower frame with reinforcing bars, then a particularly advantageous distribution of the forces, in particular tensile forces, in the upper and lower Area of the support plate guaranteed.
- the shorter transverse and longitudinal reinforcements each made of reinforcing steel, result in a particularly advantageous introduction of the forces into the reinforcement.
- longitudinal reinforcements are provided between the recesses, which are connected to the transverse reinforcements, which are connected to the upper or lower frame, a special stabilization between the recesses can be achieved.
- Fig. 3 is an upper reinforcement
- Fig. 4 is a lower reinforcement.
- the support plate 1 shown in FIG. 1 in a view from above is constructed with concrete and has two recesses 2. As shown in dashed lines in FIG. 2, these recesses are designed to taper inwards toward the top. This design makes it easier to lift a support plate off the ground.
- the support plate 1 has supports 3 for the rails, not shown.
- the longitudinal extension of the support plate, i.e. in the longitudinal direction of the rail according to arrow a, is 5,160 mm, the extension transverse to this is 2,400 mm.
- the minimum thickness of the plate is 160 mm.
- the recesses 2 are rectangular, the longer side of the rectangle being arranged parallel to the longitudinal direction of the rail and being 900 mm, whereas the width is 600 mm.
- the plate also has openings 4, which are threaded have, along which spindles are mounted variable in height, so that an exact alignment of the support plate can take place on the ground.
- the support plate has an upper reinforcement 5 and a lower reinforcement 6.
- the two reinforcements are connected via transverse reinforcements 7 made of rebar.
- the upper and lower reinforcement are shown schematically, the dimensioning of the support plate 1 and the dimensioning and positioning of the recesses 2 being shown for reasons of clarity.
- the upper and lower reinforcement 5, 6 have essentially rectangular frames 8, 9 made of rebar, which are each welded. With the upper frame 8 and the lower frame 9 (see FIG. 4) the transverse reinforcements are connected, which, as shown in FIG. 2, are guided around both frames. In addition to the transverse reinforcements 7, longitudinal reinforcements 10 made of rebar are also provided. Parallel to these
- longitudinal reinforcements further longitudinal reinforcements 11 are provided, which are shorter than those which are connected to the frame and end in front of the frame. Furthermore, shorter transverse reinforcements 12 are provided both in the upper reinforcement 5 and in the lower reinforcement 6, which on both sides of the
- Recesses 2 are arranged and are also connected at least to the longitudinal reinforcements 10 which are connected to the frame.
- reinforcements 13 made of reinforcing bar steel are provided which run obliquely to the longitudinal direction a and which reinforce the longitudinal reinforcements and
- At least one further longitudinal reinforcement 14 is provided between the two recesses 2 in the longitudinal direction a, which also consists of Reinforcing steel is made and is connected to the transverse reinforcements 7, which are each connected to the upper and lower frames 8, 9.
- Reinforcing bar steel is generally understood to mean cylindrical bars with different diameters, which additionally have ribs for better fixation in the concrete.
- carbon steel or stainless steel can be used as material for special purposes. With stainless steel, particular attention must be paid to stress corrosion cracking.
- a binding wire is usually used to connect the reinforcing bars, but there is also the possibility that they are connected by welding.
- This prefabricated support plate is provided on the underside with a rubber granulate with a thickness of 3 mm. Such rubber granules are additionally arranged on the walls of the recesses 2. The support plates are then brought with spindles over a leveled surface and then the recesses 2 or so required to fill the space between the surface and the plate and also in the recesses, for example with concrete, via further recesses.
- the support plate can also have a prestressed reinforcement, for example made of steel strands or the like, which is present in the shape under tensile stress and which is then anchored in the solidified concrete.
- a prestressed reinforcement for example made of steel strands or the like, which is present in the shape under tensile stress and which is then anchored in the solidified concrete.
