Definitions

  • the present invention relates to what is claimed in the preamble and is therefore concerned with the rotary formwork of precast concrete parts, in particular with railway sleepers.
  • elongated precast concrete parts each of which can be installed in large numbers for a building without changing one another.
  • These include ram piles for the foundation formation, noise protection wall elements, crosswise sleeper rib constructions, transoms for high-bay warehouses etc. and in particular track sleepers, which are laid in large numbers for modern railway lines.
  • the object of the present invention is to provide something new for commercial use.
  • the present invention thus proposes, in a first basic concept, a railway concrete sleeper with spaced-apart track support areas and a concrete connecting piece in between, in which it is provided that the concrete connecting piece is reinforced with slack.
  • a first essential aspect of the present invention therefore lies in the knowledge that the spaced-apart track support areas can be held securely in their position by a slack-reinforced concrete connecting piece, regardless of their high dynamic load due to trains traveling over them.
  • This longitudinal reinforcement allows tensile forces to be transmitted between the rails and ensures the stability of the track position.
  • connection piece is reinforced in one layer, which simplifies production and lowers production costs.
  • Single-layered also means reinforcement elements that are directly one above the other but are provided without stirrups.
  • the reinforcement will typically be made of corrugated steel, which prevents the reinforcement from shaking loose under the dynamic load.
  • the static crack behavior can already be calculated exactly according to DIN 1045. There is no longer any reason to fear that problems will arise from the slack reinforcement of the concrete connector during continuous operation, since extensive experience exists, particularly in the area of limited steel stresses, for example below 18 kN / cm 2 . This also applies to the support blocks.
  • reinforcement mats or baskets can be formed and used by means of helical spot welding
  • a dynamic mat i.e. a steel insert mat, which is formed only from crossing bars, which are only in certain crossing points , which are preferably in the area of low tractive force coverage, but are not welded to one another at all crossing points.
  • the arrangement of additional bars can then be provided at welding points on the edge.
  • Such reinforcement is inexpensive and ensures that even with very high load changes the steel stresses at the welding points do not endanger the load-bearing capacity.
  • Comparatively small steel diameters of, for example, 6 to 8 mm in diameter or less are preferred, which reduces the undesirable crack expansion and distributes the cracks more finely, even without having to resort to the expensive demands of a CEM for a minimum torque without cracks.
  • the concrete bridge ensures that the tracks are easier to walk on by construction and maintenance staff, which represents a further advantage in operation.
  • the concrete connector has a floor clearance during operation, especially if the sleeper is laid on a ballast track bed.
  • the floor spacing of the concrete connection piece at least in a partial area prevents the threshold from spreading i.e. As a result, there can no longer be any bearing pressure in the middle of the threshold, which leads to different bearing pressures that are difficult and / or expensive to control, that is to say essentially bending moments with changing signs.
  • the threshold is formed from two sides, namely on the track support areas on the top side and on the floor side in the area of the concrete connecting piece.
  • This can be achieved when manufacturing in the rotary formwork process in a horizontal position by using an insert in a formwork that is different from the is poured under the laterally applied concrete.
  • a concrete mass suitable for flowing under a formwork in particular self-compacting concrete and / or easily compactable concrete and / or at least concrete with a liquid consistency, for example KF according to DIN 1045, is used. It is obvious that precisely where technologically more complex types of concrete are not available, the comparatively simpler flow concrete can be used, for example in emerging or developing countries.
  • the lateral support blocks or swell blocks of the railway concrete sleeper are preferably also reinforced with only one mat, in particular a dynamic mat, and thus absorb the tensile forces from an explosive device on the sleeper river.
  • the reinforcement can be basket-shaped, in particular two baskets can be bent, which in particular overlap at the ends at the top inside. Alternatively, there can be bars converging on the inside at the bottom.
  • stirrup or basket reinforcements or suspensions may in particular be required in addition, but should be limited due to the effort involved in laying them.
  • the formwork can be made considerably easier if the vertical walls of the sleepers have an inclination of about 1:20. If the incline is over 1:40, the formwork is not made much easier; if it is below 1:10, there is no further relief, but an unhelpful change in shape due to walls that are too flat does.
  • the elongated precast concrete parts can be manufactured face to face and / or long side to long side in a rotary mold.
  • the rotary formwork preferably has an asymmetrical rolling foot, opposite from which it can be lifted with a crane.
  • a corresponding asymmetrical shape in relation to the direction of rolling or rolling can, unlike in the case of a circular or elliptically symmetrical shape, reliably avoid instability when turning, since the point of attachment, the center of gravity of the concrete part and the anchorage point of the crane lie vertically in a line.
  • this is particularly preferred when tower cranes or mobile cranes are to be used for shifting using the same method.
  • Such a procedure is again advantageous because mobile cranes are inexpensive and are readily available everywhere.
  • the mobile truck crane can, in particular, move in the direction of rotation without a claw to rotate the usually heavy formwork and thus shorten the lever arm.
  • there are alternative turning options such as a so-called Rotomat. It is preferred if, when turning, an end position securing of the parts in the formwork is provided, in particular by means of an entanglement. This prevents the concrete parts from coming loose during turning. It avoids devices on the intermediate webs that either thicken them and make them harder to clean, or that create problems when stripping over joints and edges.
  • the formwork can be spindle-supported.
  • simple stripping without pressure loading by hammers etc. is achieved, for example, using impact wrenches or the like.
  • Threshold Such a procedure makes it easier to evenly fill and / or clear excess concrete of the form, especially in the case of railway sleepers with a formwork element, and still allows drafty work.
  • top formwork is provided on the formwork from above, that is to say an insert which can be flowed under, control holes being provided in particular on the top formwork or the insert means, through which there can be a visual inspection in order to check whether actually Concrete has poured under the formwork.
  • a free flowing concrete such as flowing concrete, self-compacting concrete and / or easily compactable concrete with formwork to be used together. This ensures that there is good mold filling.
  • the formwork form can be slightly inclined with an actuator to facilitate the inflow of concrete under a cover formwork and / or vibrated with a vibrating actuator.
  • the actuator is preferably attacked on one side of the formwork form while it can sit opposite. In this way, a flow of the concrete "downhill" is supported.
  • long thresholds are replaced by short ones, there is usually no need to rework the embankment shoulder with mineral mixture, etc., as a rule.
  • the shape can be cleared from the top, which ensures that a sufficiently uniform surface is also achieved on the top areas that are not under a formwork, which moreover ensures that the shape is completely filled. It should be noted that it is also possible to use a profiled clearing blade without cover formwork, so that the use of stiffer concrete consistencies with large tolerances of the profiling may be necessary.
  • the clearing arrangement can be provided with a storage drum or the like, via which concrete is selectively added during clearing can be used to achieve the exact form filling especially in the final process.
  • a movable broaching system can be provided which serves for clearing off excess concrete and / or in particular when the clearing blade is folded away, for inserting reinforcement and / or for selectively adding concrete in the final call from a storage drum or the like, which can be tilted into an open position and / or in the case of threshold production or the like is used for the assembly of swell sets, especially by means of
  • the clearing blade can preferably be folded back or dismantled for inserting reinforcement and is otherwise arranged on a sliding yoke to enable tilting, clearing clearing movements.
  • the multifunctionality reduces the reinforcement transport costs on the construction site and / or the total transport costs of the material to be brought to the construction site, which also contributes if the drive motor of the clearing unit is removable and is designed to drive further units such as lifting traverses etc.
  • the sleeper blocks in particular can be rectangular and only separated by a thin web.
  • a formwork form which has a stable, preferably also torsionally stiff turning frame, on which two asymmetrical roller feet are provided and on which several formwork chambers are provided in an independent form.
  • These formwork chambers are preferably assembled modularly, which enables the production of smaller series even in conventional building construction with the arrangement described. In this way, purlins, beams or long supporting pieces can be produced if buildings made of appropriately arranged, repetitive structures are used.
  • the formwork elements can be combined in various ways, which allows flexible pre-assembly of a rotary mold, for example in a warehouse for component formwork modules, after which it is possible to manufacture exactly the required, different parts from one another at the construction site.
