Definitions
- the present invention relates to a method for producing a precise precast concrete part, in particular in the form of a sleeper or a slab of a solid carriageway for rail-guided vehicles, and to a pallet for producing a prestressed precast concrete part with a formwork and a tensioning device for prestressing steels.
- precast concrete parts for example, solid carriageways for rail-guided vehicles, wall elements or other beams or supports are manufactured.
- precast concrete parts for example, solid carriageways for rail-guided vehicles, wall elements or other beams or supports are manufactured.
- no particular precision is required with regard to the dimensions of the part.
- the usual tolerances that can be achieved in the concrete trade are sufficient. If other components are installed on the precast concrete parts, which must adhere to particularly tight tolerances, this is usually done with setting devices so that inaccuracies resulting from the concrete can be compensated for.
- the precast concrete part in a method for producing a precise precast concrete part, in particular in the form of a sleeper or slab for a solid carriageway for rail-guided vehicles, is first produced in a formwork as a raw part. Then, in an advantageous embodiment of the invention, it is cured by storage for several days and then, at least on the functionally relevant parts, material, for example plastic, is applied and / or machined to the predetermined size, if necessary. Due to the storage over several days, the precast concrete largely hardens, causing it to creep and shrink to almost its final state. As a result, a component is obtained which is largely true to size and will therefore hardly change even when it is later used on a construction site.
- the post-processing of the functionally relevant positions is carried out on this basis. Post-processing can also be carried out on the rail fastenings that have now been installed, which can also be machined very precisely, especially when the component has hardened.
- the raw part has rail support points which are machined to the predetermined dimensions required in the subsequent route in accordance with the individual requirements of the precast concrete part.
- components are obtained which can be provided for a special location in a route.
- Relatively simple standard components that do not differ from one another can be used for fastening the rails. This has the advantage that when replacing rails or rail fastenings no consideration has to be given to the specific place of use and any parts can therefore be used or exchanged among one another. An individual processing of the fasteners is not necessary.
- the machined location will also maintain the dimension machined in this way. If other components, such as rails, are then mounted on the solid carriageway, these must also be attached to the component very precisely.
- solid roadways can be designed so that the functionally relevant areas are relatively small. It is advisable, for example, to design the solid carriageway with bumps, which are the support points for the tracks. It is therefore only necessary to edit these bases.
- other forms can of course also be produced using the method according to the invention.
- the rest of the precast concrete part can be within a tolerance range as is customary for the production of precast concrete parts. By appropriate processing of the functionally relevant positions, an individual duel precast concrete can be manufactured. It is thus possible to also realize radii on fixed carriageways, which are composed of a large number of straight plates, by machining the corresponding support points.
- the unfinished part of the precast concrete part is manufactured in circulation. In this way it can be ensured that a constant precision of the blank is always guaranteed, whereby the machining can then also be carried out under constant conditions. The precision of the end part can thus be guaranteed.
- a large number of individual finished parts can be manufactured from standardized raw parts.
- a substantially cost-effective manufacturing process is chosen due to the circular production.
- the components can be manufactured in a multi-shift operation, whereby other shapes can be prepared and filled again while the components are drying.
- the blank and its formwork and / or a clamping device for prestressing steels of the blank are advantageously used during the manufacture of the
- Blank transported on movable pallets As a result, all manufacturing relevant components for the raw part arranged on the movable pallet and can go through the manufacturing process.
- the circulating production is divided into different processing stations.
- a cleaning station, a dowel and spindle assembly station for the slab of the slab track, a reinforcement station, a tensioning station, a concreting station with or without a compacting station, a drying chamber, a decompression and demoulding station and / or a raw part removal station are provided.
- the pallet located there is processed and prepared accordingly in order to finally produce the raw part as the end product.
- Each individual station specializes in one or more special activities. It can therefore also be advantageously provided that robots are provided in each station, which can carry out all or a large part of the required work. In order to avoid that it is not possible to continue working at individual stations because there are downtimes at other stations or because longer working periods are required there, it is advantageous if buffers are provided between two stations in which the movable pallets can be temporarily stored.
- Part of the reinforcement arranged in the blank is advantageously prestressed. In this way, a very stable raw part is obtained, which remains largely dimensionally stable even during installation on the construction site and during later use and can absorb high loads.
- the reinforcement is advantageously arranged in the transverse and longitudinal directions of the blank, in particular in the case of slabs of a solid carriageway. Typical dimensions for slabs of a solid carriageway are lengths of approx. 6.50 m and widths between 2.40 m and 3 m. Due to the arrangement of the prestressing reinforcement in the transverse direction of the blank, ie along the width of the blank, relatively short prestressing steels are required. Preloads of more than 400 tons are required on the prestressing steels per plate.
- the length of the prestressing steel requires precise and largely uniform prestressing with regard to the individual prestressing steels in order to be able to create a uniformly stable component.
- the prestressing steels are tensioned independently of the formwork or formwork surface. This in turn results in a very precise raw part and thus also a very precise end product, since the prestressing is not introduced into the formwork, but rather on our own prestressing devices specially provided for this purpose.
- the formwork only has to absorb the concrete forces and can therefore be carried out in the usual way.
- the tension can also be supported on the formwork. This is sufficient if there are no high demands on the circumferential design of the components.
- prestressing steels are clamped at the same time. If several prestressing steels are connected to one another by means of a path and / or force compensation device, a uniform tensioning of the prestressing steels is made possible.
- the prestressing steels are combined into sections and the sections are tensioned or relaxed individually, in groups or together. As a result, at least individual areas are each provided with the same clamping force, as a result of which the blank can be produced very uniformly and stably.
- the side formwork is used first and then afterwards the floor formwork removed from the raw part.
- openings are integrated in the formwork, through which stamps can be inserted.
- the raw part is separated from the floor formwork very gently.
- the later processing points are not injured and no lifting points are required. Only the component itself is raised.
- the demolding of the raw part in connection with the release of the clamping forces can be problematic.
- the problem arises from the fact that when the clamping device is released, the component is slightly compressed by the clamping forces then acting on the component and may therefore jam in the mold. It is not always possible to lift the blank from the formwork without damaging the blank.
- the raw part be detached from the floor formwork first and only then that the clamping force acts on the component. This can be done both completely and gradually, that is, for example, that the raw part is only slightly lifted from the floor formwork, then the tension is slightly or completely released and only in a next step the raw part is completely lifted off the floor formwork.
- this process takes place continuously, ie that the raw part is released from the floor formwork and the tension of the prestressing steel is released at the same time. It is important in any case that it is avoided that the component shrinks by releasing the tension to such an extent that the component is difficult to lift off the floor formwork. In the case of simple components or corresponding inserts, it is of course also possible to first relax and then demold. In order to make it easier to store the raw parts in a hardening store and to transport them there, it is advantageously provided that prestressing steels that protrude from the mold are removed. The raw parts can thus be stored upright, for example for curing.
- the raw part is advantageously transported by means of a removal trolley to the curing storage and later from the curing storage to a post-processing station.
- the raw part is processed on a concrete milling or grinding machine.
- Stationary machines of this type can be designed, for example, in a portal construction and guarantee particularly precise machining of the components.
- the components can be stored for processing according to their later assembly position and can be processed in this position.
- the later installation position in relation to the actual processing position can also be calculated by means of computational methods and the corresponding processing operations can be carried out with the computer-controlled processing machine.
- the processing which will often be machining, is carried out on the later contact surfaces of the rail or rail fastening and / or on centering points of the rigid carriageway. At the centering points, the connection to further fixed carriageway slabs is provided, so that overall a defined rail bed, which is composed of a large number of individual slabs, is created.
- the rail fastenings and possibly also the rails are already installed in the production hall, as soon as possible after processing on the solid carriageway.
- the complete panel can then be delivered to the construction site and installed in the space provided.
- the tensioning device is mounted independently of the formwork. This makes it possible to create a blank that offers the best prerequisites for later machining in order to create very precise dimensions and very tight tolerances.
- the fact that the tensioning device is mounted independently of the formwork surface means that the formwork only has to absorb the forces of the concrete, but not the forces of the tensioning device, and thus the dimensional stability of the component is ensured.
- the demoulding and clamping of the blank can be carried out independently of one another.
- the tensioning device is advantageously constructed in such a way that it has at least one pressure support and at least one pulling device.
- the pressure support is independent of the formwork and is therefore suitable for absorbing the tensile forces that act on the prestressing steel. It is structurally particularly simple if the pulling device is rotatably mounted around the pressure support.
- the force can be applied by means of the traction device by rotating around the pressure support, which is arranged between the traction device and the fastening device for prestressing steel Prestressing steels can be carried out very advantageously.
- the fastening device is tensioned and locked by means of one or more tensioning units, in particular by means of a hydraulic device.
- the clamping unit can then be removed from the fastening device and used for the next clamping process.
- the fastening device is a comb in which several prestressing steels can be hung.
- the prestressing steels are then tensioned by moving the comb in the direction of the longitudinal axis of the prestressing steels, as a result of which the prestressing steels are stretched.
- the fastening device or the comb is rotatably arranged on the pulling device.
- the prestressing steels are upset at the ends and thus form a widening. This widening creates a positive connection between the reinforcing steel and the comb. But it is also possible to create the connection between the reinforcing steel and the comb by means of nuts which are screwed over the reinforcing steel or by means of individual clamping devices.
- the comb and the form-fitting connection of the prestressing steels to the comb make it very easy to automatically hook the prestressing steels into the comb, since the prestressing steels only have to be placed over the openings of the comb in one direction.
- the combs which are each arranged at one end of the prestressing steels, are moved away from one another and thus bring about the tensioning of the prestressing steels.
- the formwork can be equipped with different inserts. This is the case, for example a solid carriageway possible to deal with different fastening systems for the rails in such a way that different shapes of the support points for the track fastening are created by the different inserts.
- the inserts which can optionally be inserted into the basic formwork, are each designed so that they are suitable for a specific method of fastening the rails. Alternatively or additionally, the inserts can be designed such that they divide the formwork into several components. As a result, several raw parts are produced simultaneously in a single pallet, each of which can be preloaded.
- the side formwork or parts thereof can be removed from the floor formwork.
- Another advantage here is that the prestressing steels can be inserted automatically into the combs. A part of the side formwork is only fastened after the steel has been inserted, which causes the raw part to be shaped.
- the side formwork has corresponding recesses or partitions so that the prestressing steel can be passed through the side formwork.
- the formwork is in each case independent of the tensioning device and can therefore also be attached or detached independently thereof.
- the clamping device By dividing the clamping device into individual sections, it is possible in an advantageous embodiment of the invention to clamp the clamping steels simultaneously or in succession.
- several prestressing steels are advantageously clamped simultaneously per section, so that a uniform prestressing and introduction of the prestressing force into the prestressing steels is made possible. This ensures an even strength of the component.
- the pallet for circulating production it is provided that it has rails or rollers. This is a movement the pallet from station to station of the rotary production can be realized very easily.
- FIG. 1 shows a production plant
- FIG. 2 shows a pallet in a front view
- FIG. 3 shows a pallet in side view
- FIG. 4 a pallet in a perspective view
- Figure 5 is a rail base.
- FIG. 1 shows the various stations of the rotary production 1 according to the invention for the production of precise precast concrete parts, in particular made of fiber concrete.
- a pallet 20 is fed to a first buffer 2 via conventional conveyors.
- the pallet 20 arrives from the buffer 2 into a cleaning station 3.
- the formwork and, if necessary, the tensioning device are cleaned in order to ensure reliable functionality.
- vacuum cleaners are available in the cleaning station 3, which are advantageously operated by means of robots and clean the pallet 20.
- the pallet 20 or the formwork After the pallet 20 or the formwork has been cleaned, it is fed to a further buffer 2.
- the dowel or spindle assembly is then carried out in station 4 from this buffer 2.
- the dowels and spindles are required in particular in a slab of a solid carriageway for rail-guided vehicles.
- the spindles will later be used on the Construction site or the position of the plate aligned for processing.
- the rails or rail fastenings for guiding the vehicle are fastened to the plate using the dowels.
- the dowel and spindle assembly can largely be carried out automatically by means of a robot (not shown).
- the pallet 20 reaches the first reinforcement station 5 from the buffer 2.
- part of the reinforcement for example meshes or prestressing steels, which are particularly designed for slabs of solid carriageways, can be inserted into the formwork.
- prestressing steel for example threaded steel, inserted transversely to this can be inserted.
- Another buffer 2 is arranged between the two reinforcement stations 5.
- the prestressing steels can be prestressed.
- the prestressed steels are fixed in the tensioning station 6, so that, for example, the hydraulic prestressing can be removed again after the prestressing steels have been fixed and can be used for the next pallet 20 or next station.
- the steel can be tensioned individually.
- the tensioning will take place at least in sections, and it may also be advantageous to tension several sections at the same time.
- the clamping of all prestressing steels can take place more quickly than if this takes place in succession, so that the throughput time of a pallet can be reduced if necessary.
- another buffer 2 is moved to by the pallet 20.
- the pallet 20 remains in the buffer 2 until the subsequent station has become free again.
- the formwork is filled with concrete, for example fiber concrete, and if necessary compacted, as a result of which the actual component is created.
- the pallet is moved into a drying chamber 9.
- a lifting device 8, 8 ′ is arranged at the beginning and at the end of the drying chamber 9. By means of these lifting lifts 8, 8 ', the pallets 20 are moved into different floors of the drying chamber 9, so that a large number of pallets 20 can be in circulation at the same time and a large number of precast concrete parts can be manufactured at the same time.
- the pallet 20 is removed from the drying chamber
- the prestressing steel is relaxed and demolded at the same time.
- the slab of the solid carriageway is completely removed from the pallet and placed on a removal trolley 12. If necessary, the built-in spindle is also rotated 20mm in height to be able to be cleaned later. The projecting ends of the prestressing steel are then separated off and the spindles are cleaned in a station 18.
- the removal carriage 12 brings the plate into a tilting station 13, in which the plate is rotated, for example, by 90 ° and placed in a warehouse.
- the concrete hardens, causing it to creep and shrink and largely assume its final dimensions.
- the concrete part has largely reached its final size and can be reworked.
- it is again placed on a trolley 12 via the tilting station 13 and fed to a further processing station 15.
- the plate is spun on in station 15. This means that the plate is aligned according to its later installation position in the solid carriageway.
- This processing station 16 can include, for example, a concrete milling machine, drilling machine or a grinding machine, with which the corresponding locations of the raw part are machined precisely and in the correct form or prepared for assembly. Because the plate has hardened, the processing of the plate has the effect that the dimensions achieved here can also be maintained in the later installation position.
- the processing of the plate can also include, for example, the milling of cutouts for guides which can be used at the ends of the plates.
- the guides which for example have a trapezoidal cross section and are made of steel, overlap two plates and thus allow the plates to be exactly aligned with one another.
- three such guides on the top, bottom and / or the side surfaces of the plate have proven to be advantageous in order to maintain a safe positioning of the plates in the x, y and z directions relative to one another until the position of the plates is final , e.g. is fixed by an infusion.
- a correspondingly angular arrangement of the recesses in relation to the longitudinal axis of the plate makes it possible to provide the plates with a polygon.
- the precast concrete part is fed to a last station, namely an assembly station 17.
- the assembly station 17 the rail fastenings and possibly even the rails themselves are mounted on the plate.
- This pre-assembled plate can later be processed very quickly on the construction site, since positioning work can be dispensed with after the specifications that have been given to the individual individual plate have already been taken into account during processing and assembly.
- the plate which is individually manufactured for a special installation location in the fixed carriageway, is numbered, if necessary, and transported to a warehouse or directly to the construction site via a removal cart 12.
- FIG. 1 A front view of a pallet 20 is shown in FIG.
- the pallet 20 is built on supports 21 and rails 22.
- Various undercuts are provided in the side formwork 24 on the end face in order to be able to connect adjacent slabs of the solid carriageway.
- the side formwork 24 can be folded down or removed from the bottom formwork, for example, by means not shown, so that the demolding of the later raw part is easily possible.
- a plurality of clamping devices 30 are provided on the pallet 20.
- Each tensioning device consists of a pressure support 31 and a pulling device 32.
- the pulling device 32 is rotatably mounted about a pivot point 33 of the pressure support 31.
- a tension rod 34 is arranged below the pressure support 31.
- a second pulling device 32 ' is fixedly arranged on the pressure support 31.
- a spindle 40 and a nut 39 cooperate with it.
- the effective length of the spindle 40 can be shortened.
- the shortening takes place, for example, by means of a hydraulic device, which acts on the spindle 40 and the latter effective length shortened.
- the pulling device 32 is rotated about the pivot point 33 and the prestressing steel 35 and the pull rod 34 are stretched.
- the shortened spindle 40 is fixed by means of the nut 39.
- the second pulling device 32 ′ can also be arranged on the pressure support 31 so as to be rotatable, identical or similar to the fastening of the pulling device 32.
- the prestressing steels 35 are connected to the upper end of the pulling device 32 and 32 '.
- the prestressing steels 35 are connected by means of a comb 36, which is connected to the upper end of the traction device 32 via a pivot point 37.
- the prestressing steels 35 are preferably suspended in the comb 36 via an upsetting.
- other cross-sectional changes already described are also possible.
- the tensioning device 30 acts independently of the formwork 23, 24, 24 ', so that deformation of the formwork 23, 24, 24' does not occur when the tension is applied.
- the tension is essentially supported by the pressure support 31, which is fastened to the frame of the pallet 20.
- the pressure support 31 is so stable that deformation of the pallet 20 is also avoided.
- FIG. 3 A side view of a pallet 20 is shown in FIG.
- the basic structure of the pallet 20 consists of the supports 21 and the rail 22.
- a large number of clamping devices 30 are arranged along the pallet 20.
- Each tensioning device 30 has a tension rod 34.
- the pull rod 34 is connected to the pulling device 32, which is supported on the pressure support 31.
- the comb 36 is arranged at the end of the pulling device 32, which lies opposite the pull rod 34.
- the comb 36 has a plurality of openings 38 in which the prestressing steels can be inserted. By actuating a tensioning device 30, a plurality of tensioning steels 35 are thus tensioned simultaneously.
- the tension of the tension rod 34 can be such that a hydraulic device accesses and shortens the spindle 40 from FIG. 2, so that two opposing combs 36 are moved apart and thereby tension the tensioning steels 35.
- Such tensioning can be carried out individually per tensioning device 30.
- several of the clamping devices 30 can also be clamped at the same time, so that the clamping of the complete pallet 20 takes place more quickly. The cycle times can thus be reduced.
- the arrangement of different clamping devices 30 results in a section-wise construction of the pallet 20.
- the pallet 20 can thereby be made more or less long without the basic structure of the pallet 20 having to be changed.
- the introduction of the clamping forces can be achieved evenly.
- a force or displacement compensation device for example with multiple bearings, can also be used in order to bring about a uniform tensile force in the prestressing steels 35. Such tools may be necessary due to the unusually short prestressing steel 35.
- FIG. 1 A perspective view of the pallet 20 is shown in FIG.
- Carriers 21, which form the basic structure of the device, are fastened to the rails 22.
- the floor formwork 23 has inserts 26, in which bumps 25 of the slab of the slab track are incorporated. Due to different fastening systems for the rails of the train to be mounted on the plate, different hump shapes are required. These can be realized by simply exchanging the inserts 26 with the pallet 20 otherwise unchanged.
- a comb 36 is arranged on each of the two pulling devices 32, in which the six prestressing steels 35 in this exemplary embodiment are received in openings 38.
- the rails 22 are used to transport the pallet 20 by being guided over transport systems.
- the pallet 20 can thus be moved from station to station. This can be done, for example, by motor-driven rollers. But it is also possible that 22 rollers are arranged in place of the rails, which in turn roll on fixed rails. However, the embodiment shown here has the advantage that the rails 22 simultaneously serve to stabilize the pallet 20 and to transport the pallet 20.
- FIG. 5 shows a detailed view of a plate 42 with a rail base.
- the rail base consists of two bumps 43 and a support 44.
- a rail 45 is fastened between the two bumps 43.
- the rail 45 is arranged on the support 44 with the aid of intermediate layers, which on the one hand bring about height compensation and on the other hand dampen the rail 45.
- the rail 45 is fastened by means of screws 47 which are anchored in the concrete of the plate 42 by means of dowels 51 and by means of clamps 49 which are supported on the hump 43 or an angle guide plate 49 and the rail foot 45.
- the angle guide plates 49 are arranged between the hump 43 and the foot of the rail 45.
- the rail 45 is held in the desired position in the horizontal direction by means of the angle guide plates 49.
- the angle guide plates 49 can be standard parts which are largely identical to one another. This makes it possible to replace or use the angle guide plates 49 when laying a rail 45.
- angle guide plates 49 and intermediate layers 46 is created by processing the inside of the humps 43 and, if necessary, the support 44 of the plate 42.
- This particular machining of the concrete on the flanks 50 and the support 44 enables the rail 45 to be precisely aligned during the manufacture of the plate 42.
- the plate 42 becomes in the area of the flanks 50 and the support 44 first manufactured with oversize.
- the present invention is not limited to the exemplary embodiments shown.
- the principle of the pallet can also be used for components other than slabs of a solid carriageway.
- supports or girders are also conceivable for this purpose, which can also be manufactured in circulation.
