Definitions
- the present invention relates to a track of concrete slabs with rails for guiding track-guided vehicles such as railways or trams, according to the preamble of claim 1 and a method for producing a corresponding track, according to the preamble of claim 14.
- the grooves made in a first plate must be exactly aligned with their grooves in the manufacture of the next plate. Corrections are hardly possible without extra effort.
- the rail track is greatly disturbed by the independent plates in a subsidence of the substrate, as the individual plates migrate out of the straight rail track and thus can even solve the attachment of the rails in the profile element. Driving can be severely endangered as a result.
- Object of the present invention is thus to provide a safe and fast to produce track for track-guided vehicles with simple and uniform components.
- the rail foot is advantageously bead-like, in particular Wedge-like designed to facilitate the mounting of the rail in the elastic sheath and also to cause a fixation of the rail in a vertical upward direction.
- the concrete slabs are finished parts, which are made uniform. At the end faces of the finished parts positioning elements and connecting elements are provided, to which the individual adjacent concrete slabs are firmly connected.
- the rails are longer than the respective plates and are pressed by the special design of the rail foot and the groove in the concrete slab in the elastic sheathing of several plates.
- the positioning elements and connecting elements, the adjacent concrete slabs are connected to each other in a defined manner and form a continuous and uniform acting track. Slight subsidence of the subsurface under a concrete slab does not immediately lead to a height offset of the concrete slab compared to the adjacent slabs, whereby the slats continue to be guided safely into the groove and the elastic sheathing.
- Rails and concrete slabs form a continuous track, which enables safe and trouble-free operation of the guided on the rails railways or trams.
- the simple and uniform plates form as well as the rails a common cohesion and thus ensure a stable track, without a variety of different components, which would produce weak points of the track due to their tolerances in the production or installation.
- the rail head of the rails installed in the plate has a greater width than the rail foot.
- the rail can be supported on the rail head on the elastic sheath and be positioned very accurately.
- the rails are endlessly welded together. This creates a very long continuous track in the manner of a fixed carriageway for high-speed lines. Due to the simple design of the track according to the invention but also for slower moving rail vehicles can be used economically.
- the elastic sheath consists of a PU layer, then a very simple production of this sheath is possible. It can either be made of a plate-shaped material and be incorporated into the precast concrete part or else correspond substantially to the shape of the rail anchored in the concrete slab. Polyurethane is very well suited for sound and shrinkage damping and is also a durable material, which can withstand the occurring environmental influences.
- the casing is a substantially endless profile, the laying of the casing in several of the plates of the track can be carried out very quickly and easily.
- individual sheathings are arranged in each individual one of the slabs of the fixed track, which are separate from the sheathing of the adjacent slab.
- the elastic sheath consists essentially of a component with a constant cross-section thickness.
- the production of the sheath is simple and inexpensive.
- the production can be made in this embodiment of a plate-shaped or extruded material.
- a molded molded element for the elastic sheath has proved to be very beneficial.
- a rail may serve as part of the mold.
- the molded element may also have different thicknesses when cast or extruded.
- the positioning elements of the concrete slabs are advantageously made of at least one cam and a pot on the end faces of the plates, which face the adjacent plates.
- a cam of a first plate acts together with a pot of an adjacent second plate, so that a kind of toothing between the two adjacent plates is formed.
- the toothing can be such that an accurate positioning of the plates already arises as a result of this, they can but also be tolerated so that an adjustment of the plates to each other is still possible on site. In any case, cause the positioning elements that adjacent plates are sufficiently interconnected to ensure the secure attachment of the rail.
- the connecting elements are arranged laterally on the plates.
- screws are suitable for this purpose, which extend on the lateral end faces of the plates from a first plate to the second adjacent plate.
- the anchoring of the screws in the adjacent plate for example, with plastic anchors, which are embedded in the plate.
- the screws may be expansion screws, whereby a defined bias can be applied to ensure a secure connection of the adjacent plates.
- the plates are laid on a split plan. This is a particularly inexpensive and in particular for vehicles in the low speed range sufficient storage of the plates.
- a sealing profile is disposed between adjacent plates.
- the sealing profile is inserted before screwing the plates and pressed tight by the screw into the gap between two plates.
- a groove of the casing has an equal or smaller width than the width of the rail web, then the clamping force of the rail can be influenced thereby.
- the elastic sheath is compressed more strongly when the rail is in its installed state, as if the groove is wider in the unloaded state. The push-through resistance of the rail is thereby increased.
- the plate is made of a material, for example made of high-strength concrete and / or with a surface structure, then it is directly passable by road vehicles. A quickly produced and cost-effective roadway can be created thereby.
- the groove is disposed in the plate or in a bump on the plate. Placed in the plate itself, for example, there is the possibility that the plate can be driven by rubber-tired vehicles.
- the construction with bump allows the use of additional soundproofing material and improvements in the prevention of rail contamination and the discharge of rainwater or snow.
- the hump has interruptions to the plate. Rainwater accumulated between the rails can thereby flow off to the side of the plate.
- the rails are arranged in the plate in each case a groove and guided with an elastic sheathing.
- the plate is installed after the production of the plate and the groove in the driveway and finally the rails are pressed into the elastic sheath of several successive plates. Another assembly of the rail is usually not required, which makes a very rapid installation of the rail can be done.
- the rail is also very accurately positioned and stored at the same time damped.
- the plates are positioned in the track to each other and firmly connected to each other, so creates a continuous track, which allows a positionally accurate and permanent attachment of the rails in the plates.
- the plate is preferably concreted with trays, which are removed after curing of the plate from the plate again.
- the training rails can already create the exact required shape of the groove. But it is also possible that they only pretend the later groove shape and then the exact shape, for example, created by a machining. This can bring advantages in demoulding the teaching rail, if necessary, thereby undercuts or too low draft angles are avoided.
- the elastic sheathing is concreted in as a built-in component together with the training rail and remains after the removal of the training rail from the board in the board, a separate assembly of the sheathing is not required.
- the plate is thus already prepared for mounting the rail.
- the dimensions of rail and elastic sheathing and the elastic sheath is installed after removing the teaching rail in the plate, so in particular when using a sheath, which is designed as a substantially endless profile, a very fast assembly of profile and rail respectively. There are thus fewer shocks in the sheath, which improves the durability of the sheath. It is then preferably the elastic sheath after installation of the plate in the guideway in the, preferably installed in several of the plates.
- the groove In order to produce the groove particularly accurate, it is advantageously prepared by a grinding and or milling. It can be completely incorporated into the plate.
- the basic shape is created with oversize while the machining process produces the exact shape.
- the elastic sheath is made independently of the plate, and the sheath is positioned as a fitting during the concreting of the finished part in the formwork of the plate, so it is ensured that with a factory accuracy, the sheath, which is the holder of the rail, accurately positioned with respect to the gauge or with respect to a curve of the track is mapped.
- the sheath which is the holder of the rail, accurately positioned with respect to the gauge or with respect to a curve of the track is mapped.
- the plate is disengaged and installed in the driveway. Finally, the rail is pressed into the elastic sheath of several plates.
- the rails outside the plate are endlessly welded together and then inserted into the sheathing, an additional connection of the individual precast concrete slabs is created.
- the endlessly welded rails form, in addition to the positioning and connecting elements provided in the plates, an additional fixing of adjacent plates to one another. A safe driving is also ensured by the thus ensured tracking.
- connection of the plates is advantageously carried out by means of a screw.
- the plates are pressed against each other and thus ensure a solid track.
- FIG. 1 shows a plan view of a precast concrete panel 1, which is connected to adjacent precast concrete panels 1 'and 1 "in the precast concrete slab 1.
- Two rails 2 are laid parallel to each other.
- the rails 2 are each continuously guided in a casing 3.
- positioning elements in the form of two cams 4 and two pots 5 are arranged.
- the cams 4 and the pots 5 engage with one another and thus effect a positioning of the precast concrete panels 1, 1 'and 1 "relative to each other, as well as connecting elements with which the panels 1, 1' and 1" are connected to one another.
- the connecting elements are screws 6, which are from the lateral edge of the respective plate 1, 1 'and 1 "obliquely into the adjacent plate 1, 1' and 1" are screwed.
- the two adjacent plates are thereby pulled tightly together and thus form a solid track, which allows a continuous and continuous storage of the rail 2 in the casing 3.
- the plates 1, 1 'and 1 "are connected to one another in such a way that they become less sensitive to isolated subsidence of the substrate and are also suitable for a higher load bearing than if they would cause a discontinuous mounting of the rails 2, if they did not would be interconnected.
- FIG. 2 shows a section of an end face of the precast concrete panel 1. It can be seen that the rail 2 is recessed in a groove of the precast concrete panel 1.
- the rail 2 is surrounded by the casing 3, which is arranged tightly in the groove of the plate 1.
- the rail 2 consists of a rail head 7, a rail web 8 and a rail foot 9.
- the rail foot 9 is formed bead-like and thus causes a fixed arrangement of the rail within the casing 3, since the rail web 8 is made thinner than the rail foot 9.
- the width b of the rail foot 9 is also less than the width B of the groove in the plate 1.
- the width B is dimensioned so that the rail foot 9 when pressing or removing the rails 2 through the area in which is in the installed state of the rail web 8, can be moved through.
- the width B must also be dimensioned such that the width b of the rail foot 9 can pass this point even with the casing 3 pressed together.
- the rail head 7 is also wider than the rail foot. 9
- the cam 4 is conical in order to effect a simple insertion and centering of adjacent plates 1.
- FIG. 3 is a section through the positioning elements of two plates 1 and 1 'shown.
- the positioning elements consist of the cam 4 and the pot 5, in which the cam 4 protrudes.
- Cam 4 and pot 5 are tapered to effect centering of the plates 1 and 1 'when placed against each other.
- a sealing profile 10 is inserted at the top of the plates 1 and 1'. When the panels 1 and 1 'are assembled and bonded together, the sealing profile 10 is crushed and seals the gap against ingress of rainwater.
- FIG. 4 is a section of two side surfaces of two plates 1 and 1 'shown with corresponding connecting elements.
- the connecting elements consist of screws 6, which are starting from a first plate 1, 1 'obliquely screwed into the second plate 1', 1.
- a dowel 11 in the plate 1, 1 ' is inserted at the corresponding point.
- the screws 6 are advantageously expansion screws, so that a bias is applied to press the plates 1, 1 'with a defined force to each other.
- FIG. 5 shows a section on an end face of the plate 1 in a laid state.
- the plate 1 is laid in this embodiment on a split plan 12, which is arranged on a support layer 13.
- the rail 2 is not completely recessed in the plate 1, but substantially flush with a cover layer 14.
- the cover layer 14, which may be for sealing the plate 1 or, for example, a road surface for road traffic, is above the plate 1 applied.
- the sheath 3 is also arranged in the region of the cover layer 14 between the cover layer 14 and the rail 2.
- the cover layer 14 may be produced together with the precast concrete panel 1 or subsequently applied to the precast concrete panel 1.
- the plate 1 can be wholly or partly made of a concrete, for example of a high-strength concrete, whereby the top of the plate 1 is directly accessible by road vehicles.
- a die is inserted into the formwork, which images the roadway structure in the top of the plate 1.
- a brushstroke structure can be produced on the upper side of the plate 1 or the cover layer 14, if this is carried out in this way.
- n ' is smaller than n when the rail 2 is not installed, then the elastic casing is compressed more strongly, when the rail 2 is in its installed state, as if the groove in the unloaded state is equal to the rail web 8.
- FIGS. 6 and 7 show an illustration of the invention, in which the rail 2 is installed in a bump 20 of the precast concrete panel 1.
- the rail 2 is once installed up to the rail head 7 up in the elastic sheath.
- the rail head 7 is free of the casing.
- FIG. 8 a side view of a plate 1 with bump 20 is shown. It can be seen that under the rail 2 or the shroud, not shown here, an opening to the plate 1 out again and again, can flow through the accumulated between the two parallel rails 2 a track rain or melt water.
- the openings are interruptions of the hump 20, which are preferably arranged in the region of notches in the plate 1, as shown here, which serve as predetermined breaking points of the plate 1.

Die Aufgabe wird gelöst mit einem Fahrweg mit den Merkmalen des Anspruchs 1 und die Schritte des Anspruchs 14.The object is achieved with a track with the features of
Der Schienenfuß ist vorteilhafterweise wulstartig, insbesondere keilartig ausgeführt, um die Montage der Schiene in der elastischen Ummantelung zu erleichtern und außerdem eine Fixierung der Schiene in vertikaler Richtung nach oben zu bewirken.The rail foot is advantageously bead-like, in particular Wedge-like designed to facilitate the mounting of the rail in the elastic sheath and also to cause a fixation of the rail in a vertical upward direction.
Die Betonplatten sind Fertigteile, welche gleichförmig hergestellt sind. An den Stirnseiten der Fertigteile sind Positionierungselemente und Verbindungselemente vorgesehen, an welchen die einzelnen benachbarten Betonplatten fest miteinander verbunden sind. Die Schienen sind länger als die jeweiligen Platten und werden durch die spezielle Ausbildung des Schienenfußes und der Nut in der Betonplatte in die elastische Ummantelung mehrerer Platten eingedrückt. Durch die Positionierungselemente und Verbindungselemente sind die benachbarten Betonplatten in definierter Weise miteinander verbunden und bilden einen durchgehenden und einheitlich wirkenden Fahrweg. Leichte Setzungen des Untergrundes unter einer Betonplatte führen nicht sofort zu einem Höhenversatz der Betonplatte im Vergleich zu den benachbarten Platten, wodurch die Schienen weiterhin sicher in den Nut und der elastischen Ummantelung geführt sind. Schienen und Betonplatten bilden einen kontinuierlichen Fahrweg, welcher einen sicheren und störungsunempfindlichen Betrieb der auf den Schienen geführten Eisenbahnen oder Straßenbahnen ermöglicht. Die einfachen und gleichförmigen Platten bilden ebenso wie die Schienen einen gemeinsamen Zusammenhalt und sorgen somit für einen stabilen Fahrweg, ohne einer Vielzahl unterschiedlicher Bauteile, welche durch ihre Toleranzen in der Herstellung oder Verlegung Schwachstellen des Fahrweges erzeugen würden.The concrete slabs are finished parts, which are made uniform. At the end faces of the finished parts positioning elements and connecting elements are provided, to which the individual adjacent concrete slabs are firmly connected. The rails are longer than the respective plates and are pressed by the special design of the rail foot and the groove in the concrete slab in the elastic sheathing of several plates. The positioning elements and connecting elements, the adjacent concrete slabs are connected to each other in a defined manner and form a continuous and uniform acting track. Slight subsidence of the subsurface under a concrete slab does not immediately lead to a height offset of the concrete slab compared to the adjacent slabs, whereby the slats continue to be guided safely into the groove and the elastic sheathing. Rails and concrete slabs form a continuous track, which enables safe and trouble-free operation of the guided on the rails railways or trams. The simple and uniform plates form as well as the rails a common cohesion and thus ensure a stable track, without a variety of different components, which would produce weak points of the track due to their tolerances in the production or installation.
Erfindungsgemäß hat der Schienenkopf der in die Platte eingebauten Schienen eine größere Breite als deren Schienenfuß. Dadurch kann sich die Schiene über deren Schienenkopf auf der elastischen Ummantelung abstützen und sehr genau positioniert werden.According to the rail head of the rails installed in the plate has a greater width than the rail foot. As a result, the rail can be supported on the rail head on the elastic sheath and be positioned very accurately.
Vorteilhafterweise sind die Schienen endlos miteinander verschweißt. Hierdurch entsteht ein sehr langer kontinuierlicher Fahrweg nach Art einer festen Fahrbahn für Hochgeschwindigkeitsstrecken. Durch die einfache Bauweise ist der erfindungsgemäße Fahrweg aber auch für langsamer fahrende Schienenfahrzeuge wirtschaftlich einsetzbar.Advantageously, the rails are endlessly welded together. This creates a very long continuous track in the manner of a fixed carriageway for high-speed lines. Due to the simple design of the track according to the invention but also for slower moving rail vehicles can be used economically.
Besteht die elastische Ummantelung aus einer PU-Schicht, so ist eine sehr einfache Herstellung dieser Ummantelung möglich. Sie kann entweder aus einem plattenförmigen Material hergestellt und in das Betonfertigteil eingearbeitet sein oder aber auch im wesentlichen der Form der in der Betonplatte verankerten Schiene entsprechen. Polyuhrethan ist sehr gut zur Schall- und Schwindungsdämpfung geeignet und ist auch ein dauerhaftes Material, welches den auftretenden Umwelteinflüssen widerstehen kann.If the elastic sheath consists of a PU layer, then a very simple production of this sheath is possible. It can either be made of a plate-shaped material and be incorporated into the precast concrete part or else correspond substantially to the shape of the rail anchored in the concrete slab. Polyurethane is very well suited for sound and shrinkage damping and is also a durable material, which can withstand the occurring environmental influences.
Ist die Ummantelung ein im wesentlichen endloses Profil, so ist die Verlegung der Ummantelung in mehrere der Platten des Fahrweges sehr schnell und einfach durchzuführen. Es kann aber auch vorgesehen sein, dass in jeder einzelnen der Platten der festen Fahrbahn einzelne Ummantelungen angeordnet sind, die separat von der Ummantelung der benachbarten Platte sind.If the casing is a substantially endless profile, the laying of the casing in several of the plates of the track can be carried out very quickly and easily. However, it may also be provided that individual sheathings are arranged in each individual one of the slabs of the fixed track, which are separate from the sheathing of the adjacent slab.
Vorteilhafterweise besteht die elastische Ummantelung im wesentlichen aus einem Bauteil mit im Querschnitt gleichbleibender Dicke. Hierdurch ist die Herstellung der Ummantelung einfach und kostengünstig möglich. Die Herstellung kann gerade bei dieser Ausführung aus einem plattenförmigen oder extrudierten Material erfolgen. Auch hat sich ein gegossenes Formelement für die elastische Ummantelung als sehr vorteilhaft erwiesen. Als Teil der Form kann beispielsweise eine Schiene dienen. Das Formelement kann, wenn es gegossen oder extrudiert ist auch unterschiedliche Dicken aufweisen.Advantageously, the elastic sheath consists essentially of a component with a constant cross-section thickness. As a result, the production of the sheath is simple and inexpensive. The production can be made in this embodiment of a plate-shaped or extruded material. Also, a molded molded element for the elastic sheath has proved to be very beneficial. For example, a rail may serve as part of the mold. The molded element may also have different thicknesses when cast or extruded.
Die Positionierungselemente der Betonplatten bestehen vorteilhafterweise aus zumindest einer Nocke und einem Topf an den Stirnseiten der Platten, welche den benachbarten Platten zugewandt sind. Eine Nocke einer ersten Platte wirkt dabei mit einem Topf einer benachbarten zweiten Platte zusammen, so dass eine Art Verzahnung zwischen den beiden benachbarten Platten entsteht. Die Verzahnung kann dabei derartig sein, dass bereits hierdurch eine genaue Positionierung der Platten zueinander entsteht, sie können aber auch so toleriert sein, dass eine Justierung der Platten zueinander vor Ort noch ermöglicht ist. Jedenfalls bewirken die Positionierungselemente, dass benachbarte Platten ausreichend miteinander verbunden sind, um die sichere Befestigung der Schiene zu gewährleisten.The positioning elements of the concrete slabs are advantageously made of at least one cam and a pot on the end faces of the plates, which face the adjacent plates. A cam of a first plate acts together with a pot of an adjacent second plate, so that a kind of toothing between the two adjacent plates is formed. The toothing can be such that an accurate positioning of the plates already arises as a result of this, they can but also be tolerated so that an adjustment of the plates to each other is still possible on site. In any case, cause the positioning elements that adjacent plates are sufficiently interconnected to ensure the secure attachment of the rail.
Um benachbarte Platten einfach miteinander zu verbinden, ist es vorteilhaft, wenn die Verbindungselemente seitlich an den Platten angeordnet sind. Es bieten sich hierfür insbesondere Schrauben an, welche an den seitlichen Stirnflächen der Platten von einer ersten Platte bis in die zweite benachbarte Platte hineinreichen. Die Verankerung der Schrauben in der benachbarten Platte erfolgt beispielsweise mit Kunststoffdübeln, welche in der Platte eingelassen sind. Die Schrauben können Dehnschrauben sein, wodurch eine definierte Vorspannung aufgebracht werden kann, um eine sichere Verbindung der benachbarten Platten zu gewährleisten.To easily connect adjacent plates together, it is advantageous if the connecting elements are arranged laterally on the plates. In particular, screws are suitable for this purpose, which extend on the lateral end faces of the plates from a first plate to the second adjacent plate. The anchoring of the screws in the adjacent plate, for example, with plastic anchors, which are embedded in the plate. The screws may be expansion screws, whereby a defined bias can be applied to ensure a secure connection of the adjacent plates.
Vorteilhafterweise werden die Platten auf einem Splittplanum verlegt. Dies ist eine besonders kostengünstige und insbesondere für Fahrzeuge im niedrigen Geschwindigkeitsbereich ausreichende Lagerung der Platten.Advantageously, the plates are laid on a split plan. This is a particularly inexpensive and in particular for vehicles in the low speed range sufficient storage of the plates.
Um zu vermeiden, dass Regenwasser in den Spalt zwischen zwei benachbarten Platten eindringt und den Untergrund ausspült oder die Schrauben korrodiert, ist es besonders vorteilhaft, wenn zwischen benachbarten Platten ein Dichtungsprofil angeordnet ist. Das Dichtungsprofil wird vor der Verschraubung der Platten eingelegt und durch die Verschraubung dicht in den Spalt zwischen zwei Platten eingepresst.In order to avoid that rainwater penetrates into the gap between two adjacent plates and rinses the substrate or corrodes the screws, it is particularly advantageous if a sealing profile is disposed between adjacent plates. The sealing profile is inserted before screwing the plates and pressed tight by the screw into the gap between two plates.
Weist eine Nut der Ummantelung eine gleiche oder geringere Breite als die Breite des Schienensteges auf, so kann hierdurch die Klemmkraft der Schiene beeinflußt werden. Bei einer geringeren Breite der Nut wird die elastische Ummantelung stärker zusammengepresst, wenn sich die Schiene in ihrem eingebauten Zustand befindet, als wenn die Nut in unbelastetem Zustand breiter ist. Der Durchschubwiderstand der Schiene ist hierdurch vergrößert.If a groove of the casing has an equal or smaller width than the width of the rail web, then the clamping force of the rail can be influenced thereby. With a smaller width of the groove, the elastic sheath is compressed more strongly when the rail is in its installed state, as if the groove is wider in the unloaded state. The push-through resistance of the rail is thereby increased.
Ist die Platte aus einem Material, beispielsweise aus hochfestem Beton und/oder mit einer Oberflächenstruktur ausgeführt, so ist sie mit Straßenfahrzeugen direkt befahrbar. Eine schnell herstellbare und kostengünstige Fahrbahn kann hierdurch geschaffen werden.If the plate is made of a material, for example made of high-strength concrete and / or with a surface structure, then it is directly passable by road vehicles. A quickly produced and cost-effective roadway can be created thereby.
Die Nut ist in der Platte oder in einem Höcker auf der Platte angeordnet. In der Platte selbst angeordnet, ergibt sich beispielsweise die Möglichkeit, dass die Platte von gummibereiften Fahrzeugen befahren werden kann. Die Bauweise mit Höcker ermöglicht die Verwendung von zusätzlichem Schallschutzmaterial und Verbesserungen bei der Vermeidung von Verschmutzung der Schiene und der Ableitung von Regenwasser oder Schnee.The groove is disposed in the plate or in a bump on the plate. Placed in the plate itself, for example, there is the possibility that the plate can be driven by rubber-tired vehicles. The construction with bump allows the use of additional soundproofing material and improvements in the prevention of rail contamination and the discharge of rainwater or snow.
Insbesondere zur besseren Wasserableitung ist es vorteilhaft, wenn der Höcker Unterbrechungen bis zur Platte aufweist. Zwischen den Schienen angesammeltes Regenwasser kann dadurch zur Seite der Platte hin abfließen.In particular, for better drainage, it is advantageous if the hump has interruptions to the plate. Rainwater accumulated between the rails can thereby flow off to the side of the plate.
Bei dem erfindungsgemäßen Verfahren zur Herstellung eines Fahrweges aus Betonplatten mit Schienen zur Führung von spurgeführten Fahrzeugen wie Eisenbahnen oder Straßenbahnen werden die Schienen in der Platte in jeweils einer Nut angeordnet und mit einer elastischen Ummantelung geführt.In the inventive method for producing a driveway of concrete slabs with rails for guiding track-guided vehicles such as railways or trams, the rails are arranged in the plate in each case a groove and guided with an elastic sheathing.
Die Platte wird nach der Herstellung der Platte und der Nut in den Fahrweg eingebaut und schließlich werden die Schienen in die elastische Ummantelung mehrerer aufeinanderfolgender Platten eingedrückt. Eine weitere Montage der Schiene ist in der Regel nicht erforderlich, wodurch eine sehr schnelle Montage der Schiene erfolgen kann. Die Schiene ist darüber hinaus sehr genau positioniert und gleichzeitig gedämpft gelagert.The plate is installed after the production of the plate and the groove in the driveway and finally the rails are pressed into the elastic sheath of several successive plates. Another assembly of the rail is usually not required, which makes a very rapid installation of the rail can be done. The rail is also very accurately positioned and stored at the same time damped.
Erfindugsgemäß werden die Platten in dem Fahrweg zueinander positioniert und fest miteinander verbunden, so entsteht ein kontinuierlicher Fahrweg, welcher eine positionsgenaue und dauerhafte Befestigung der Schienen in den Platten ermöglich.According to the invention, the plates are positioned in the track to each other and firmly connected to each other, so creates a continuous track, which allows a positionally accurate and permanent attachment of the rails in the plates.
Die Platte wird vorzugsweise mit Lehrschienen betoniert, welche nach dem Aushärten der Platte aus der Platte wieder entfernt werden. Die Lehrschienen können dabei bereits die genaue erforderliche Form der Nut schaffen. Es ist aber auch möglich, dass sie die spätere Nutform nur angedeutet vorgeben und die exakte Form anschließend, beispielsweise durch eine spanende Bearbeitung geschaffen wird. Dies kann Vorteile beim Entformen der Lehrschiene bringen, wenn dadurch gegebenenfalls Hinterschneidungen oder zu geringe Formschrägen vermieden werden.The plate is preferably concreted with trays, which are removed after curing of the plate from the plate again. The training rails can already create the exact required shape of the groove. But it is also possible that they only pretend the later groove shape and then the exact shape, for example, created by a machining. This can bring advantages in demoulding the teaching rail, if necessary, thereby undercuts or too low draft angles are avoided.
Wird die elastische Ummantelung als Einbauteil zusammen mit der Lehrschiene einbetoniert und verbleibt nach dem Entfernen der Lehrschiene aus der Platte in der Platte, so ist eine separate Montage der Ummantelung nicht erforderlich. Die Platte ist somit bereits für die Montage der Schiene vorbereitet.If the elastic sheathing is concreted in as a built-in component together with the training rail and remains after the removal of the training rail from the board in the board, a separate assembly of the sheathing is not required. The plate is thus already prepared for mounting the rail.
Entspricht die Lehrschiene den Maßen von Schiene und elastischer Ummantelung und wird die elastische Ummantelung nach dem Entfernen der Lehrschiene in die Platte eingebaut, so kann insbesondere bei Verwendung einer Ummantelung, welche als im wesentlichen endloses Profil ausgebildet ist, eine sehr schnelle Montage von Profil und Schiene erfolgen. Es sind dadurch auch weniger Stöße in der Ummantelung vorhanden, welche die Dauerhaftigkeit der Ummantelung verbessert. Es wird dann vorzugsweise die elastische Ummantelung nach dem Einbau der Platte in den Fahrweg in die, vorzugsweise in mehrere der Platten eingebaut.Corresponds to the training track the dimensions of rail and elastic sheathing and the elastic sheath is installed after removing the teaching rail in the plate, so in particular when using a sheath, which is designed as a substantially endless profile, a very fast assembly of profile and rail respectively. There are thus fewer shocks in the sheath, which improves the durability of the sheath. It is then preferably the elastic sheath after installation of the plate in the guideway in the, preferably installed in several of the plates.
Um die Nut besonders maßgenau herstellen zu können, wird sie vorteilhafterweise durch eine Schleif- und oder Fräsbearbeitung hergestellt. Sie kann dabei vollständig in die Platte eingearbeitet werden. Bei Verwendung einer Lehrschiene wird in diesem Falle die grundsätzliche Form mit Übermaß geschaffen, während die spanende Bearbeitung die genaue Form herstellt.In order to produce the groove particularly accurate, it is advantageously prepared by a grinding and or milling. It can be completely incorporated into the plate. When using a In this case, the basic shape is created with oversize while the machining process produces the exact shape.
Wird zuerst die elastische Ummantelung unabhängig von der Platte hergestellt, und wird die Ummantelung als Einbauteil während des Betonierens des Fertigteiles in der Schalung der Platte positioniert, so wird sichergestellt, dass mit einer werksmäßigen Genauigkeit die Ummantelung, welche die Halterung der Schiene darstellt, exakt positioniert bzgl. der Spurweite oder bzgl. eines Kurvenverlaufes des Gleises abgebildet wird. Um eine gewünschte Oberfläche der Platte zu erhalten, ist es vorteilhaft, wenn sie auf dem Kopf, also die spätere Oberseite der Platte nach unten in der Schalung, betoniert wird. Durch eine spezielle Formgebung der Schalung kann die entsprechende Oberfläche der Platte erhalten werden. Nach dem Aushärten des Betons wird die Platte entschalt und in den Fahrweg eingebaut. Schließlich wird die Schiene in die elastische Ummantelung mehrerer Platten eingedrückt.First, the elastic sheath is made independently of the plate, and the sheath is positioned as a fitting during the concreting of the finished part in the formwork of the plate, so it is ensured that with a factory accuracy, the sheath, which is the holder of the rail, accurately positioned with respect to the gauge or with respect to a curve of the track is mapped. In order to obtain a desired surface of the plate, it is advantageous if it is concreted on the head, so the later top of the plate down in the formwork. By a special shaping of the formwork, the corresponding surface of the plate can be obtained. After hardening of the concrete, the plate is disengaged and installed in the driveway. Finally, the rail is pressed into the elastic sheath of several plates.
Durch die Verwendung der Ummantelung als Einbauteil bei der Herstellung der Fertigteilplatte wird eine hohe Präzision erzielt und zudem zusätzliche Kosten für das Einbringen der elastischen Ummantelung in eine separat gefertigte Nut vermieden. Außerdem wird sichergestellt, dass es keine Toleranzen zwischen der Ummantelung und der Nut des Betonfertigteiles gibt, in welche Regenwasser eindringen kann und die Ummantelung oder den Beton zerstören könnte. Im Gegensatz zum Ausgießen eines Spaltes zwischen der Schiene und der Nut mit einem Elastomer ist bei der vorliegenden Erfindung auch gewährleistet, dass das Elastomer tatsächlich die Schiene gleichmäßig umgibt und keine ungewollten Hohlräume durch ein unsachgemäßes Ausgießen entstehen. Durch das Umgießen der fertigen Ummantelung mit dem Beton der Fertigteilplatte wird eine dauerhafte, gleichmäßige und sehr genaue Positionierung und Festlegung der Schiene bewirkt. Durch das Eindrücken der Schiene in die Ummantelung ist eine schnelle Montage und bei Bedarf auch Demontage der Schiene gewährleistet. Eine Justierung der Schiene vor Ort ist in der Regel nicht erforderlich.By using the casing as a built-in part in the manufacture of the precast panel high precision is achieved and also avoided additional costs for the introduction of the elastic sheath into a separately produced groove. It also ensures that there are no tolerances between the shell and the groove of the precast concrete element, in which rainwater can penetrate and destroy the shell or concrete. In contrast to pouring a gap between the rail and the groove with an elastomer in the present invention also ensures that the elastomer actually surrounds the rail evenly and no unwanted cavities caused by improper pouring. By pouring the finished casing with the concrete of the precast panel a permanent, uniform and very accurate positioning and fixing of the rail is effected. By impressing the rail in the shroud a quick installation and, if necessary, disassembly of the rail is guaranteed. An adjustment of the rail on site is usually not required.
Besonders vorteilhaft ist es, wenn eine Schiene zur Positionierung der Ummantelung beim Betonieren der Betonfertigteilplatte verwendet wird und die Schiene nach dem Ausheben der Platte aus der Schalung wieder entfernt wird. Hierdurch wird auf einfache Weise sichergestellt, dass die Ummantelung exakt die Form frei hält, welche für den Einbau der späteren Schiene nötig ist. Dadurch, dass die Schiene in die elastische Ummantelung eingedrückt und aus dieser auch wieder herausgezogen werden kann, ist die Verwendung eines solchen Schienenstückes allein zur Positionierung der Ummantelung beim Betonieren sehr vorteilhaft.It is particularly advantageous if a rail for positioning the sheathing is used when concreting the precast concrete slab and the rail is removed again after the slab has been lifted out of the formwork. As a result, it is ensured in a simple manner that the casing exactly keeps the shape free, which is necessary for the installation of the later rail. Characterized in that the rail can be pressed into the elastic sheath and pulled out of this again, the use of such a rail piece alone for positioning the shroud during concreting is very beneficial.
Werden die Schienen außerhalb der Platte endlos miteinander verschweißt und anschließend in die Ummantelung eingesetzt, so entsteht eine zusätzliche Verbindung der einzelnen Betonfertigteilplatten miteinander. Die endlos verschweißten Schienen bilden neben den in den Platten vorgesehenen Positionierungs- und Verbindungselementen eine zusätzliche Fixierung benachbarter Platten zueinander. Ein sicherer Fahrbetrieb wird durch die damit gewährleistete Spurhaltung ebenfalls gewährleistet.If the rails outside the plate are endlessly welded together and then inserted into the sheathing, an additional connection of the individual precast concrete slabs is created. The endlessly welded rails form, in addition to the positioning and connecting elements provided in the plates, an additional fixing of adjacent plates to one another. A safe driving is also ensured by the thus ensured tracking.
Besonders vorteilhaft ist es, wenn die endlos miteinander verschweißten Schienen in die Ummantelung eingedrückt werden. Dies geschieht beispielsweise dadurch, dass ein Schienenverlegefahrzeug auf den bereits verlegten Schienen fährt und die neu zu verlegenden Schienenabschnitte auf die Nut aufsetzt. Durch das Eigengewicht des Schienenverlegefahrzeuges wird die Schiene allmählich in die Nut und zwischen die Ummantelung eingedrückt. Es erfolgt somit ein kontinuierliches und sehr schnell durchführbares Verfahren zur Verlegung der endlos miteinander verschweißten Schienen in der Nut der Fertigteilplatte.It is particularly advantageous if the endlessly welded rails are pressed into the sheathing. This happens, for example, in that a rail laying vehicle travels on the already laid rails and the newly laid rail sections touches the groove. Due to the weight of the rail laying vehicle, the rail is gradually pressed into the groove and between the sheath. There is thus a continuous and very quickly feasible method for laying the endless welded together rails in the groove of the precast slab.
Für einen Fahrweg für Eisenbahnen oder Straßenbahnen, welche nur mit einer niedrigen Geschwindigkeit und geringen Gewichten betrieben werden, ist es kostengünstig und ausreichend, wenn die Platten auf einem Splittplanum verlegt werden. Es ist hierdurch eine ausreichende Tragfähigkeit gewährleistet. Selbstverständlich kann auch ein Verguss der Fertigteilplatten mit dem Untergrund in bekannter Weise erfolgen.For a railroad or tramway railway operating at a low speed and low weight, it is inexpensive and sufficient if the panels are on a split plan be moved. It is thereby ensured sufficient carrying capacity. Of course, a casting of precast slabs with the ground can be done in a known manner.
Die Verbindung der Platten erfolgt vorteilhafterweise mittels einer Verschraubung. Die Platten werden dabei aneinandergepresst und sorgen somit für einen festen Fahrweg.The connection of the plates is advantageously carried out by means of a screw. The plates are pressed against each other and thus ensure a solid track.
Um das Eindringen von Regenwasser in die Spalte zwischen zwei Fahrwegplatten zu vermeiden, ist es vorteilhaft, wenn die Stöße zwischen zwei benachbarten Platten abgedichtet werden.In order to avoid the ingress of rainwater into the gaps between two track plates, it is advantageous if the joints between two adjacent plates are sealed.
Wird eine Nut der Ummantelung mit einer gleichen oder geringeren Breite als der Breite des Schienensteges hergestellt, so kann hierdurch die Klemmkraft der Schiene beeinflußt werden.If a groove of the casing is produced with a width which is equal to or less than the width of the rail web, the clamping force of the rail can thereby be influenced.
