- the two segments thus fit very closely together. Due to the profiling, which can be performed wavy or toothed, the friction of the two segments is significantly increased together. If the two segments are pressed together, then thrust forces and torsional moments can be transferred very well. If the joints are additionally glued, the result is a bearing behavior which is comparable to a monolithic prestressed concrete bridge.

- milling or a combination of different mechanical processing steps can, for example, be considered.
- the contact surface can be discussed. The segments thus fit very closely together and are pressed close to each other.
- the individual segments are placed against each other at the machined, in particular ground contact points. This results in a precisely predetermined arrangement of the individual segments together whereby a predetermined course of the bridge can be achieved.
- the two segments can be butted against each other, resulting in the relative position of the adjacent segments to each other. But they can also be interconnected by means of a gearing.
- the gearing is produced precisely by means of milling and / or grinding.
- the achievable tolerances of the bridge profile and the individual segments to each other are excellent compared to achievable with conventional methods values.
- the segments are placed together in exact position, whereby subsequently the resulting cavities are cast in addition to the contact surfaces. This creates areas in which transversal forces are removed can be.
- the filled in the cavities potting material acts as a bar, which is located exactly between the two segments and thus optimally can absorb shear forces and torsional moments.
- the segments are first clamped against one another and then the cavities are poured out between the contact surfaces.
- the ground contact surfaces for the positioning of the segments are obtained and the cavities are optimally utilized for the transmission of power by means of the casting compounds cast into them. Open joints are completely avoided.

- a roadway is created, which is fast and economical to produce.
- An additional road surface is not required.
- by the solid juxtaposition of the individual segments creates a virtually seamless roadway, which is particularly good and comfortable to drive.
- damage due to penetrating into pores or joints freezing water is almost impossible, since the top of the carriageway plate by the type of production has virtually no pores and the joints between the individual segments due to their milled contact surfaces match each other.
- a segment prefabricated bridge according to the invention consists of prefabricated segments of concrete, which are placed against one another in the supporting and / or longitudinal direction.
- the contact surface is at least partially machined, in particular ground. This allows a virtually gapless transition between two segments when they are placed against one another.
- the segments are designed with a single or multi-cell box cross-section with floor and deck plates, which are connected to webs. This creates a stable and resilient construction of the bridge.
- the segments are plate-shaped and arranged shear-resistant on a carrier.
- the segments can be placed on a steel or concrete beam, which have shear bolts, which engage in recesses of the segments. The recesses can then be potted in the subsequent composite.

Due to the dense structure of the concrete used, in particular in connection with the introduced surface texture, the requirements for high grip, noise emissions, mechanical abrasion by tires and durability with respect to frost and de-icing salt attack and chemical attack, for example, by acid rain, excellent fulfilled.
- FIG. 1 is a section through a side view of a segment prefabricated bridge 1 with in the supporting direction against contact surfaces 14 juxtaposed plurality of segments 3,4 and 5 shown.
- the segments extend transversely to the bridge 1 and are lined up in the longitudinal or supporting direction.
- the segment prefabricated bridge 1 has two fields, which rest on three bearings 2. In the area of the bearing 2, two end segments 3 and a middle segment 4 are arranged.

- the tendons 6 are mounted in the end segments 3 in recesses 18 with tendon heads.
- Each segment 3, 4 and 5 consists in this embodiment of a bottom 8 and a carriageway plate 9, which are interconnected by means of a plurality of webs 13 and form a box cross-section.
- tendons 10 are arranged, which are stretched after concreting the respective segment 3, 4 and 5 and provide additional strength of the segments 3, 4 and 5.
- 9 cavities 11 are arranged both in the bottom 8 and in the carriageway plate.
- the cavities 11 are filled after compression of the individual segments 3, 4 and 5 with potting material and thus provide thrust toothing of the individual segments 3, 4 and 5.
- Above and below the cavity 11 are in the bottom 8, the deck plate 9 and the Webs 13 as part of contact surfaces 14 contact points 12 are arranged.
- the contact points 12 are ground and / or milled after the production of each individual segment 3, 4 and 5 according to the requirements of their slot within the bridge 1. So it is possible by this mechanical processing, same mass-produced segments 3, 4 and 5, in particular but the segments 5, individually modify, so that, for example, a slope or radii or crests can be mapped in the segment prefabricated bridge 1.
- FIG. 2 is a front view of a segment 5 of a segment prefabricated bridge 1 is shown. It is in this case a three-cell box cross-section shown with a bottom 8, a deck plate 9 and four bars 13.

- the cavity 11 has two openings 15. These openings 15 are used for filling a potting compound.
- the potting compound is filled in one of the two openings until it runs out of the other opening 15. This ensures that air pockets are largely avoided. This results in a very effective shear toothing of two juxtaposed segments 3, 4 or 5.

- the use of a high-strength concrete meets the requirements for a directly drivable surface of the carriageway plate 9.
- a special superstructure of segment prefabricated bridge 1 is no longer necessary, especially since the individual segments 3, 4 and 5 already have high strength by the shear gearing of the poured cavities 11 and an additional concrete is no longer required.
- the baffles can be set up as needed and road changes to adapt to the traffic can be easily realized. If the load collective is increased, the load capacity of the bridge can be increased by additional tendons.
- FIG. 3 shows a section through a side view of another segment prefabricated bridge 1 ', which is similar to the segment prefabricated bridge 1 of Figure 1 and 2 stored and designed. The difference is that individual segments 50, 51 divide the bridge 1 'not transversely to the supporting direction but along the supporting direction. There are thus individual longitudinal members present, which are divided along the supporting direction and connected to each other.

Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Segmentfertigteilbrücke aus vorgefertigten, in Trag- und/oder Längsrichtung mit an Kontaktflächen aneinandergesetzten Segmenten aus Beton und eine entsprechende Segmentfertigteilbrücke.The present invention relates to a method for producing a segment prefabricated bridge from prefabricated, in support and / or longitudinal direction with each other at contact surfaces juxtaposed concrete segments and a corresponding segment prefabricated bridge.
Segmentfertigteilbrücken werden üblicherweise im sogenannten Match-Cast-Verfahren hergestellt. Hierfür werden die Segmente im Fertigteilwerk oder auf der Baustelle einzeln hergestellt. Hierzu wird das neue Segment gegen die Kontaktfläche des vorherigen Segmentes betoniert. Das vorherige Segment dient dabei als Teil der Schalung für die innere Kontaktfläche des neu zu betonierenden Segmentes. Dabei werden Profilierungen, welche in der äußeren Kontaktfläche durch eine entsprechende Schalung vorgesehen werden, von dem neuen Segment passgenau übernommen. Die beiden Segmente passen hierdurch sehr genau ineinander. Durch die Profilierung, welche gewellt oder verzahnt ausgeführt sein kann, wird die Reibung der beiden Segmente aneinander deutlich erhöht. Werden die beiden Segmente aneinandergepresst, so können Schubkräfte und Torsionsmomente sehr gut übertragen werden. Werden die Fugen zusätzlich verklebt, so entsteht ein Tragverhalten, welches vergleichbar einer monolithischen Spannbetonbrücke ist.Segment prefabricated bridges are usually produced in the so-called match-cast process. For this purpose, the segments are produced individually in the precast plant or on the construction site. For this purpose, the new segment is concreted against the contact surface of the previous segment. The previous segment serves as part of the formwork for the inner contact surface of the newly concreted segment. Here, profiles which are provided in the outer contact surface by a corresponding formwork, taken over by the new segment accurately. The two segments thus fit very closely together. Due to the profiling, which can be performed wavy or toothed, the friction of the two segments is significantly increased together. If the two segments are pressed together, then thrust forces and torsional moments can be transferred very well. If the joints are additionally glued, the result is a bearing behavior which is comparable to a monolithic prestressed concrete bridge.
Zur Erhöhung der Tragkraft wird zusätzlich eine Aufbetonschicht auf die Segmentfertigteilbrücke aufgetragen. Die Aufbetonschicht bildet ein durchgehendes Betonband, welches durch eine entsprechende Gestaltung oder Ausstattung der Oberfläche mit beispielsweise Asphalt eine Fahrbahn für gummibereifte Fahrzeuge bildet.To increase the carrying capacity, a concrete layer is additionally applied to the prefilled segment bridge. The concrete layer forms a continuous concrete strip, which forms a roadway for rubber-tired vehicles by an appropriate design or equipment of the surface with, for example, asphalt.
Nachteilig bei den bekannten Segmentfertigteilbrücken ist einerseits, dass zur Erzielung einer ausreichenden Festigkeit eine durchgehende Aufbetonschicht erforderlich ist. Außerdem sind die einzelnen Segmente hinsichtlich ihrer Form identisch hergestellt. Zum Ausgleich von Bautoleranzen müssen daher einzelne Ortbetonverfüllungen oder bewehrte Ortbetonsegmente eingesetzt werden.A disadvantage of the known segment prefabricated bridges is on the one hand, that in order to achieve sufficient strength, a continuous concrete layer is required. In addition, the individual segments are made identical in shape. To compensate for building tolerances therefore single Ortbetonverfüllungen or reinforced Ortbetonsegmente must be used.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Segmentfertigteilbrücke zu schaffen, welche eine hohe Tragfestigkeit aufweist, trotz Serienfertigung auf individuelle Brückenverläufe abgestimmt ist und schnell und wirtschaftlich herstellbar ist.Object of the present invention is to provide a segment prefabricated bridge, which has a high structural strength, despite series production is tuned to individual bridge gradients and is fast and economical to produce.
Die Aufgabe wird gelöst mit den Merkmalen der unabhängigen Patentansprüche.The object is solved with the features of the independent claims.
Bei einem erfindungsgemäßen Verfahren zur Herstellung einer Segmentfertigteilbrücke aus vorgefertigten, in Trag- und/oder Längsrichtung mit an Kontaktflächen aneinandergesetzten Segmenten aus Beton werden die Profile der aneinandergesetzten Kontaktflächen der Segmente erfindungsgemäß zumindest teilweise mechanisch bearbeitet, insbesondere geschliffen. An Stelle des Schleifens, welches bzgl. der damit erreichbaren Genauigkeit bevorzugt ist, kann beispielsweise auch ein Fräsen oder eine Kombination verschiedener mechanischer Bearbeitungsschritte in Frage kommen. Hierdurch kann auf die individuellen Erfordernisse der einzelnen Segmente je nach Einbauort des jeweiligen Segmentes an der Brücke bzgl. der Kontaktfläche eingegangen werden. Die Segmente passen hierdurch sehr genau aneinander und werden dicht an dicht aneinandergepresst. Durch das Bearbeiten können gerade Brückenverläufe realisiert werden, es können aber ebenso Radien oder Kuppen der Brücken geschaffen werden, wobei stets die Kontaktflächen der Segmente fest aneinander anliegen, sobald die Segmente miteinander verspannt werden. Durch das feste aneinander liegen der Kontaktflächen wird eine hervorragende Kraftübertragung erzeugt. Außerdem werden Ausgleichsbereiche von Bautoleranzen durch Ortbetonverfüllungen oder bewehrte Ortbetonsegmente, welche die Kraftaufnahme der Brücke schwächen und einen erheblichen Bauaufwand bedeuten, vermieden.In a method according to the invention for producing a segmented prefabricated bridge from prefabricated, in the support and / or longitudinal direction with segments of concrete set against contact surfaces, the profiles of the juxtaposed contact surfaces of the segments are at least partially mechanically processed, in particular ground. Instead of grinding, which is preferred with regard to the accuracy that can be achieved with it, milling or a combination of different mechanical processing steps can, for example, be considered. In this way, the individual requirements of the individual segments depending on the installation location of the respective segment on the bridge with respect. The contact surface can be discussed. The segments thus fit very closely together and are pressed close to each other. By editing straight bridge courses can be realized, but it can also be created radii or crests of the bridges, with always the contact surfaces of the segments firmly abut each other as soon as the segments are clamped together. Due to the fixed contact surfaces lie together an excellent power transmission is generated. Furthermore Compensation areas of building tolerances are avoided by Ortbetonverfüllungen or reinforced Ortbetonsegmente, which weaken the power of the bridge and mean a significant construction cost.
Durch das mechanische Bearbeiten, insbesondere das Schleifen der Kontaktflächen entsprechend ihrer späteren Einbaulage können gezielt Bereiche geschaffen werden, welche sehr exakt aufeinander abgestimmt sind und plan aufeinander liegen, auch wenn die Segmente abweichend von einer Standardlage verbaut werden.By mechanical processing, in particular the grinding of the contact surfaces according to their subsequent installation position targeted areas can be created, which are very precisely matched to each other and lie flat on each other, even if the segments are installed deviating from a standard situation.
Durch die Bearbeitung aneinandergesetzter Kontaktflächen der Segmente werden Kontaktstellen und Hohlräume gebildet, wodurch nicht nur eine korrespondierende Verzahnung, wie es bei einer Match-Cast-Fertigung der Fall ist, geschaffen wird, sondern es werden Bereiche hergestellt, welche für die spätere Verbindung der einzelnen Segmente genutzt werden können.By processing juxtaposed contact surfaces of the segments contact points and cavities are formed, whereby not only a corresponding toothing, as is the case with a match-cast manufacturing, is created, but it will be made areas, which for the subsequent connection of the individual segments can be used.
Die einzelnen Segmente werden dabei an den bearbeiteten, insbesondere geschliffenen Kontaktstellen aneinandergesetzt. Hierdurch entsteht eine exakt vorbestimmte Anordnung der einzelnen Segmente aneinander wodurch ein vorbestimmter Verlauf der Brücke erzielt werden kann. Die zwei Segmente können stumpf aneinandergepresst werden, wodurch sich die relative Lage der aneinandergrenzenden Segmente zueinander ergibt. Sie können aber auch mittels einer Verzahnung miteinander verbunden werden. Die Verzahnung wird dabei mittel Fräsen und/oder Schleifen exakt hergestellt. Die erreichbaren Toleranzen des Brückenverlaufs und der einzelnen Segmente zueinander sind dabei im Vergleich zu mit herkömmlichen Verfahren erreichbaren Werten hervorragend.The individual segments are placed against each other at the machined, in particular ground contact points. This results in a precisely predetermined arrangement of the individual segments together whereby a predetermined course of the bridge can be achieved. The two segments can be butted against each other, resulting in the relative position of the adjacent segments to each other. But they can also be interconnected by means of a gearing. The gearing is produced precisely by means of milling and / or grinding. The achievable tolerances of the bridge profile and the individual segments to each other are excellent compared to achievable with conventional methods values.
Die Segmente werden positionsgenau aneinandergesetzt, wodurch anschließend die dadurch neben den Kontaktflächen entstehenden Hohlräume vergossen werden. Hierdurch entstehen Bereiche, in welchen Querkräfte abgetragen werden können. Das in die Hohlräume eingefüllte Vergussmaterial wirkt hierdurch als Riegel, welcher exakt zwischen den beiden Segmenten angeordnet ist und somit optimal Schubkräfte und Torsionsmomente aufnehmen kann.The segments are placed together in exact position, whereby subsequently the resulting cavities are cast in addition to the contact surfaces. This creates areas in which transversal forces are removed can be. The filled in the cavities potting material acts as a bar, which is located exactly between the two segments and thus optimally can absorb shear forces and torsional moments.
Um die Segmente fest miteinander zu verbinden, ist es vorteilhaft, wenn sie mit Spanngliedern mit externer und/oder interner verbundloser Vorspannung aneinandergespannt werden. Üblicherweise werden externe Spannglieder verwendet, welche beispielsweise in dem Kastenquerschnitt geführt werden. Aber auch eine interne Vorspannung kann je nach Bauausführung Vorteile ergeben. Die Spannglieder bewirken dabei, dass auch bei höchster Belastung die einzelnen Segmente vorgespannt bleiben.To connect the segments firmly together, it is advantageous if they are clamped together with tendons with external and / or internal compositeless bias. Usually external tendons are used, which are guided for example in the box cross-section. But also an internal bias can result depending on the construction benefits. The tendons ensure that even with the highest load, the individual segments remain biased.
Vorteilhafterweise werden die Segmente erst aneinandergespannt und anschließend die Hohlräume zwischen den Kontaktflächen ausgegossen. Hierdurch werden die geschliffenen Kontaktflächen für die Positionierung der Segmente erhalten und die Hohlräume optimal für die Kraftübertragung mit Hilfe der in sie eingegossenen Vergussmassen ausgenutzt. Offene Fugen werden dabei vollständig vermieden.Advantageously, the segments are first clamped against one another and then the cavities are poured out between the contact surfaces. As a result, the ground contact surfaces for the positioning of the segments are obtained and the cavities are optimally utilized for the transmission of power by means of the casting compounds cast into them. Open joints are completely avoided.
Besonders vorteilhaft ist es, wenn die Oberseite der Fahrbahnplatte mit einer Besenstrichstruktur versehen wird und direkt befahrbar ist. Durch die Herstellung der Segmente, welche mit der Fahrbahnplatte nach unten oder zur Seite hin erfolgt, wird eine sehr dichte Oberseite der Fahrbahnplatte erzielt. Wird nun beispielsweise der Schalboden oder die Schalwand mit einer Gummimatrize mit Besenstrichstruktur versehen, so erhält die Oberseite der Fahrbahnplatte eben diese Besenstrichstruktur mit einer für den Fahrbetrieb mit gummibereiften Fahrzeugen optimal ausgeführten Fahrbahn. Besonders durch diese Maßnahme wird eine Fahrbahn geschaffen, welche schnell und wirtschaftlich herstellbar ist. Ein zusätzlicher Fahrbahnbelag ist nicht erforderlich. Insbesondere auch durch das feste Aneinanderpressen der einzelnen Segmente entsteht eine praktisch fugenlose Fahrbahn, welche besonders gut und komfortabel befahrbar ist. Außerdem ist eine Beschädigung durch in Poren oder Fugen eindringendes gefrierendes Wasser nahezu ausgeschlossen, da die Oberseite der Fahrbahnplatte durch die Art der Herstellung nahezu keine Poren aufweist und die Fugen zwischen den einzelnen Segmenten aufgrund ihrer geschliffenen Kontaktflächen exakt aufeinander passen.It is particularly advantageous if the upper side of the roadway slab is provided with a brushstroke structure and is directly passable. By making the segments, which takes place with the deck plate down or to the side, a very dense top of the deck plate is achieved. If, for example, the formwork floor or the formwork wall is provided with a rubber mold with a brushstroke structure, then the upper side of the carriageway panel receives precisely this brushstroke structure with a roadway optimally designed for driving with rubber-tired vehicles. Especially by this measure, a roadway is created, which is fast and economical to produce. An additional road surface is not required. In particular, by the solid juxtaposition of the individual segments creates a virtually seamless roadway, which is particularly good and comfortable to drive. In addition, damage due to penetrating into pores or joints freezing water is almost impossible, since the top of the carriageway plate by the type of production has virtually no pores and the joints between the individual segments due to their milled contact surfaces match each other.
Eine erfindungsgemäße Segmentfertigteilbrücke besteht aus vorgefertigten, in Trag- und/oder Längsrichtung mit an Kontaktflächen aneinandergesetzten Segmenten aus Beton. Die Kontaktfläche ist zumindest teilweise mechanisch bearbeitet, insbesondere geschliffen. Hierdurch wird ein praktisch spaltloser Übergang zwischen zwei Segmenten ermöglicht, wenn diese aneinandergesetzt sind.A segment prefabricated bridge according to the invention consists of prefabricated segments of concrete, which are placed against one another in the supporting and / or longitudinal direction. The contact surface is at least partially machined, in particular ground. This allows a virtually gapless transition between two segments when they are placed against one another.
Vorzugsweise sind die Segmente mit einem ein- oder mehrzelligen Kastenquerschnitt mit Boden- und Fahrbahnplatten, die mit Stegen verbunden sind, ausgeführt. Hierdurch entsteht ein stabiler und belastbarer Aufbau der Brücke.Preferably, the segments are designed with a single or multi-cell box cross-section with floor and deck plates, which are connected to webs. This creates a stable and resilient construction of the bridge.
In einer alternativen Ausführung sind die Segmente plattenförmig ausgebildet und auf einem Träger schubfest angeordnet. Die Segmente können auf einem Stahl- oder Betonträger aufgelegt werden, welche Schubdübel aufweisen, die in Aussparungen der Segmente eingreifen. Die Aussparungen können anschließend im nachträglichen Verbund vergossen werden.In an alternative embodiment, the segments are plate-shaped and arranged shear-resistant on a carrier. The segments can be placed on a steel or concrete beam, which have shear bolts, which engage in recesses of the segments. The recesses can then be potted in the subsequent composite.
Für eine zusätzliche Festigkeit der Segmente ist eine Quervorspannung der Segmente vorgesehen.For additional strength of the segments, a transverse bias of the segments is provided.
Durch die entsprechend der späteren Einbaulage mechanisch bearbeiteten, insbesondere geschliffenen Kontaktflächen der Segmente wird eine sehr gute Anlagefläche der beiden aneinandergesetzten Segmente geschaffen. Auch können individuelle Brückenverläufe geschaffen werden, indem bzgl. der Hoch- oder Längsachse der Segmente von der Orthogonalen abweichende Winkel der Kontaktflächen bearbeitet werden. Hierdurch wird ein Polygonzug der einzelnen aneinandergesetzten Segmente geschaffen, welcher für den individuellen Bau einer Brücke besonders vorteilhaft ist. So können nicht nur horizontale Radien ebenso wie Kuppen realisiert werden, sondern auch Gefälle zum Ablaufen von Regenwasser bereits in den einzelnen Segmenten durch eine entsprechende mechanische Bearbeitung der Kontaktflächen der aneinandergesetzten Segmente geschaffen werden.Due to the according to the subsequent installation position mechanically machined, in particular ground contact surfaces of the segments a very good contact surface of the two juxtaposed segments is created. Also, individual bridge courses can be created by the vertical or longitudinal axis of the segments are processed by the orthogonal deviating angle of the contact surfaces. As a result, a polygon of individual juxtaposed segments is created, which is particularly advantageous for the individual construction of a bridge. So not only horizontal radii as well as crests can be realized, but also gradient for running rainwater already in the individual segments by a corresponding mechanical processing of the contact surfaces of the juxtaposed segments are created.
Die Profilierung aneinandergesetzter Kontaktflächen der Segmente weist neben Kontaktstellen auch Hohlräume auf, die durch einen Verguss zur Kraftübertragung genutzt werden. Es wird hierdurch ein sehr stabiles Brückenbauwerk geschaffen, welches trotz einer Serienfertigung der Segmente eine individuelle Bauweise bei höchster Festigkeit ermöglicht.The profiling of juxtaposed contact surfaces of the segments, in addition to contact points and cavities, which are used by a casting for power transmission. It is hereby created a very stable bridge structure, which allows an individual design with maximum strength despite a series production of the segments.
Die Kontaktstellen sind derart bearbeitet, dass die Segmente dicht aneinander zu setzen sind, wodurch die Segmente einen nahezu fugenlosen Kontakt ausbilden. Die Dauerhaftigkeit der Brücke wird hierdurch positiv beeinflusst. Darüber hinaus wird auch die Kraftübertragung wesentlich verbessert.The contact points are machined so that the segments are close to each other, whereby the segments form a virtually seamless contact. The durability of the bridge is thereby positively influenced. In addition, the power transmission is significantly improved.
Vorteilhafterweise sind die Segmente mittels einer Verzahnung schubfest miteinander verbunden. Die Verzahnung wird dabei mittel Fräsen und/oder Schleifen exakt hergestellt, um den gewünschten Verlauf der Brücke, ohne Versatz der einzelnen Segmente zu erhalten.Advantageously, the segments are sheared together by means of a toothing. The toothing is produced by means of milling and / or grinding exactly to obtain the desired course of the bridge, without offset of the individual segments.
Die Segmente sind positionsgenau aneinandergesetzt, wodurch bei einer entsprechenden Gestaltung der Kontaktflächen abgedichtete Hohlräume entstehen, welche mit Vergussmaterial verfüllt werden. Als Vergussmaterial kommt Vergussmörtel in Frage, welcher in die Hohlräume eindringt und sich dort verfestigt.The segments are placed together in exact position, which results in a corresponding design of the contact surfaces sealed cavities, which are filled with potting material. As grout is grout in question, which penetrates into the cavities and solidifies there.
In vorteilhafter Weise sind in dem Hohlraum, welcher durch das Aneinandersetzen der Segmente entsteht, Einfüllöffnungen für das Vergussmaterial vorgesehen. Hierzu wird das Vergussmaterial vorteilhafterweise in eine Einfüllöffnung eingegossen, bis es aus einer weiteren Öffnung des Hohlraumes, welcher vorteilhafterweise am anderen Ende des Hohlraumes angeordnet ist, herausfließt. Hierdurch ist sichergestellt, dass, weitgehend ohne Lufteinschlüsse, der Hohlraum vollständig mit Vergussmasse verfüllt ist.Advantageously, filling openings for the potting material are provided in the cavity, which is formed by the juxtaposition of the segments. For this purpose, the potting material is advantageously poured into a filling opening until it flows out of a further opening of the cavity, which is advantageously arranged at the other end of the cavity. This ensures that, largely without air pockets, the cavity is completely filled with potting compound.
Um die mit Vergussmasse nach dem Einfüllen vergossenen Einfüllöffnungen von Witterungseinflüssen weitgehend fernzuhalten, ist es vorteilhaft, wenn die Einfüllöffnungen in Einbauposition des Segmentes unten angeordnet sind. Hierdurch kann Regen- oder Schmelzwasser nicht in den Hohlraum eindringen und hier zu Beschädigungen führen. Im Übrigen ist durch das passgenaue Verspannen der einzelnen Segmente eine weitgehend dichte Kontaktstelle zwischen den beiden Segmenten geschaffen, welche ebenfalls das Eindringen von Wasser verhindert.In order largely to keep the potting compound poured after filling filling openings from the weather, it is advantageous if the filling openings are arranged in the installed position of the segment below. As a result, rain or melt water can not penetrate into the cavity and cause damage here. Incidentally, a largely dense contact point between the two segments is created by the accurate clamping of the individual segments, which also prevents the ingress of water.
Vorteilhafterweise ist das Vergussmaterial Beton- bzw. Vergussmörtel. Dieser dünnflüssige Beton fließt sehr gut in den Hohlraum und füllt ihn vollständig aus. Zusätzlich kann selbstverständlich auch die Kontaktstelle mit Klebstoff versehen sein, um auch hier noch eine zusätzliche Verbindung der beiden Segmente und eine Abdichtung zu erzielen.Advantageously, the potting material concrete or grout. This low-viscosity concrete flows very well into the cavity and fills it completely. In addition, of course, the contact point may also be provided with adhesive in order to achieve an additional connection of the two segments and a seal here as well.
Sind die einzelnen Segmente mit externen und/oder internen Spanngliedern aneinandergespannt, so wird eine besonders einfache und gute Kraftübertragung und Momentaufnahme erzielt.If the individual segments are clamped together with external and / or internal tendons, a particularly simple and good force transmission and snapshot is achieved.
Weisen die Segmente externe und/oder interne Spanngliedführungen und Umlenksättel zur Spanngliedführung auf, so ist eine gezielte Krafteinleitung gewährleistet.If the segments have external and / or internal tendon guides and deflection saddles for tendon guidance, a targeted introduction of force is ensured.
Sind interne Spannglieder insbesondere in Kragarmen der Segmente angeordnet, so wird zuverlässig verhindert, dass sich die Kragarme gegeneinander verschieben können.Are internal tendons arranged in particular in cantilevers of the segments, it is reliably prevented that the cantilevers can move against each other.
Ist an den Kontaktflächen eine Zentriereinrichtung, beispielsweise ein Zentrierkegel, der mit einer eingearbeiteten Tasche des benachbarten Segmentes zusammenwirkt, so werden die Segmente passgenau zueinander montiert und es wird eine zusätzliche Abtragung einer Schubkraft ermöglicht.Is at the contact surfaces a centering device, such as a centering cone, which cooperates with an incorporated pocket of the adjacent segment, the segments are mounted accurately to each other and it is an additional removal of a thrust allows.
Ist an Kanten der Segmente ein Elastomerband angeordnet, so werden Kantenabplatzungen beim Transport und der Montage der Segmente vermieden. Außerdem wird eine zusätzliche Abdichtung der Fuge zwischen zwei benachbarten Segmenten erhalten.If an elastomeric strip is arranged on edges of the segments, edge chipping during transport and assembly of the segments is avoided. In addition, an additional seal of the joint between two adjacent segments is obtained.
Sind an Endsegmenten der Brücke Aussparungen zur Aufnahme von Spanngliedköpfen angeordnet, so können die Endsegmente in die Übergangskonstruktion der Brücke integriert werden. Die Endsegmente können auch die Brückenlager mit aufnehmen.If recesses for receiving tendon heads are arranged on end segments of the bridge, then the end segments can be integrated into the transition structure of the bridge. The end segments can also accommodate the bridge bearings.
Bildet die Oberseite der Fahrbahnplatte des Segmentes direkt eine Fahrbahn für gummibereifte Fahrzeuge, so ist ein sehr einfaches Brückenbauwerk aus Betonfertigteilen geschaffen, welches direkt für den Fahrbetrieb eingesetzt werden kann. Ein zusätzlicher Aufbeton oder eine Asphaltschicht zur Verstärkung der Segmentfertigteilbrücke oder zum Betrieb als eine Fahrbahn mit einer entsprechenden Lauffläche ist hierdurch nicht mehr erforderlich. Die Kosten des Baus einer solchen Segmentfertigteilbrücke sind hierdurch günstiger und insbesondere wird die Bauzeit deutlich verkürzt, da auf das Aufbringen von Aufbeton oder einer Asphaltschicht verzichtet werden kann.Forms the top of the deck slab of the segment directly a roadway for rubber-tired vehicles, so a very simple bridge structure made of precast concrete elements is created, which can be used directly for driving. An additional concrete or an asphalt layer for reinforcing the segment prefabricated bridge or for operation as a roadway with a corresponding tread is thereby no longer required. The cost of building such a segment prefabricated bridge are thereby cheaper and in particular the construction time is significantly reduced because it can be dispensed with the application of concrete or an asphalt layer.
Um den Fahrbetrieb der Oberseite der Fahrbahnplatte in vorteilhafter Weise zu ermöglichen, ist diese mit einer Besenstrichstruktur versehen. Die Fahrbahnplatte ist hierdurch direkt befahrbar. Weitere Maßnahmen hinsichtlich der Bearbeitung der Oberseite der Fahrbahnplatte sind nicht erforderlich.In order to allow the driving operation of the top of the roadway panel in an advantageous manner, this is provided with a brush stroke structure. The carriageway plate This makes it directly accessible. Further measures regarding the processing of the top of the carriageway plate are not required.
Um ein besonders stabiles und insbesondere für den Fahrbetrieb besonders geeignetes Segment zu schaffen, ist dieses aus selbstverdichtenden Beton hergestellt. Durch das dichte Gefüge des verwendeten Betons, insbesondere in Zusammenhang mit der eingebrachten Oberflächentextur, werden die Anforderungen bezüglich hoher Griffigkeit, Schallemission, mechanischer Abrasion durch Reifen und Dauerhaftigkeit bezüglich Frost- und Tausalz-Angriff und chemischem Angriff beispielsweise durch sauren Regen, hervorragend erfüllt.In order to create a particularly stable and especially for driving particularly suitable segment, this is made of self-compacting concrete. Due to the dense structure of the concrete used, in particular in connection with the introduced surface texture, the requirements for high grip, noise emissions, mechanical abrasion by tires and durability with respect to frost and de-icing salt attack and chemical attack, for example, by acid rain, excellent fulfilled.
Besonders die Verwendung eines hochfesten Betons gemäß DIN-EN 206-1 dient dem Einsatz als direkt befahrbare Fahrbahnplatte. Beschädigungen durch den Fahrbetrieb oder durch Witterungseinflüsse wird hierdurch vorgebeugt. Wie sich herausgestellt hat, ist dieser hochfeste Beton hervorragend dafür geeignet alle Anforderungen einer Betonfahrbahn zu erfüllen. Es wird damit eine strapazierfähige und griffige Fahrbahn erhalten, die äußerst wirtschaftlich herstellbar ist.In particular, the use of a high-strength concrete according to DIN-EN 206-1 is used as a directly passable roadway slab. Damage caused by driving or due to the effects of weather is thereby prevented. As it turns out, this high-strength concrete is ideally suited to meet all the requirements of a concrete carriageway. It is thus a durable and non-slip roadway, which is extremely economical to produce.

Jedes Segment 3, 4 und 5 besteht bei diesem Ausführungsbeispiel aus einem Boden 8 und einer Fahrbahnplatte 9, welche mittels mehrerer Stege 13 miteinander verbunden sind und einen Kastenquerschnitt bilden. In der Fahrbahnplatte 9 sind weitere Spannglieder 10 angeordnet, welche nach dem Betonieren des jeweiligen Segmentes 3, 4 und 5 gespannt werden und für eine zusätzliche Festigkeit der Segmente 3, 4 und 5 sorgen.Each
Bei dem vorliegenden Ausführungsbeispiel sind sowohl in dem Boden 8 als auch in der Fahrbahnplatte 9 Hohlräume 11 angeordnet. Die Hohlräume 11 werden nach dem Zusammenpressen der einzelnen Segmente 3, 4 und 5 mit Vergussmaterial aufgefüllt und sorgen somit für eine Schubverzahnung der einzelnen Segmente 3, 4 und 5. Oberhalb und unterhalb des Hohlraumes 11 sind in dem Boden 8, der Fahrbahnplatte 9 und den Stegen 13 als Bestandteil von Kontaktflächen 14 Kontaktstellen 12 angeordnet. Die Kontaktstellen 12 werden nach der Herstellung jedes einzelnen Segmentes 3, 4 und 5 entsprechend den Anforderungen an ihren Einbauplatz innerhalb der Brükke 1 geschliffen und/oder gefräst. So ist es durch diese mechanische Bearbeitung möglich, gleiche serienmäßig hergestellte Segmente 3, 4 und 5, insbesondere aber die Segmente 5, individuell abzuändern, so dass beispielsweise ein Gefälle oder Radien oder Kuppen in der Segmentfertigteilbrücke 1 abgebildet werden können.In the present embodiment, 9

Der Hohlraum 11 weist zwei Öffnungen 15 auf. Diese Öffnungen 15 dienen zum Einfüllen einer Vergussmasse. Die Vergussmasse wird dabei in eine der beiden Öffnungen solange eingefüllt, bis sie aus der anderen Öffnung 15 herausläuft. Hierdurch ist sichergestellt, dass Lufteinschlüsse weitgehend vermieden werden. Es entsteht hierdurch eine sehr wirkungsvolle Schubverzahnung zweier aneinandergereihter Segmente 3, 4 oder 5.The
Der Bereich der Kontaktfläche 14, welcher nicht den Hohlraum 11 oder die Öffnung 15 aufweist, dient als Kontaktstelle 12. Die Kontaktstelle 12 ist mechanisch, vorzugsweise durch Schleifen bearbeitet und gewährleistet somit eine sehr exakte Lage und Form. Hierdurch kann das Segment 5 optimal mit dem benachbarten Segment 3, 4 oder 5 korrespondieren und bewirkt, dass ein weitgehend dichter Kontakt zwischen den beiden aneinandergesetzten Segmenten 3, 4 und 5 besteht. Durch eine Bearbeitung der Kontaktflächen 14 im Bereich der Kontaktstellen 12 derart, dass sie einen vorbestimmten Winkelversatz zur Hoch- oder zur Längsachse des Segmentes 5 aufweisen, kann ein polygonartiger Verlauf der Segmentfertigteilbrücke 1 erzielt werden. Hierdurch sind vorbestimmte Lagen der Segmentfertigteilbrücke 1 sehr einfach und genau zu erzielen.The area of the

In den Kragarmen des Segmentes 5 sind interne Spannglieder 20 angeordnet. Sie bewirken, dass die Kragarme auch unter großer Belastung formgenau zu den Kragarmen der benachbarten Segmente erhalten bleiben.In the cantilevers of the
An den Umlaufkanten des Segmentes 5 ist ein Elastomerband 21 angeordnet. Durch das Elastomerband 21 werden Beschädigungen des Segmentes bei Transport und Montage vermieden. Zusätzlich wird eine Abdichtung der Fuge mit dem Elastomerband erhalten. Gleiche Wirkung erzielt auch ein Dichtungsschlauch anstelle des Elastomerbandes 20.At the peripheral edges of the
An den Stegen 13 sind schematisch Zentriereinrichtungen 22 dargestellt. Sie erleichtern die Montage, indem beispielsweise kegelförmige Stifte in entsprechend ausgebildete Aussparungen eingreifen. Beim Zusammenführen benachbarter Segmente werden diese exakt zueinander positioniert.Centering
Die Oberfläche der Fahrbahnplatte 9 kann in Form eines Besenstriches oder einer anderen Struktur betoniert sein. Die Segmentfertigteilbrücke 1 kann dadurch mit ihrer Oberfläche bereits als Fahrbahn für gummibereifte Fahrzeuge dienen. Besonders die Verwendung eines hochfesten Betons erfüllt die Anforderungen an eine direkt befahrbare Oberfläche der Fahrbahnplatte 9. Ein spezieller Oberbau der Segmentfertigteilbrücke 1 ist nicht mehr erforderlich, zumal die einzelnen Segmente 3, 4 und 5 durch die Schubverzahnung der ausgegossenen Hohlräume 11 bereits eine hohe Festigkeit aufweisen und ein zusätzlicher Aufbeton nicht mehr erforderlich ist. Darüber hinaus weist die exakte Bearbeitung der Kontaktflächen 14 im Bereich der Kontaktstellen 12 eine dichte Verbindung benachbarter Segmente 3, 4 und 5 auf. Hierdurch wird nicht nur das Segment 3, 4, und 5 selbst vor Zerstörung beispielsweise durch eintretendes Wasser bewahrt, sondern auch die Spannglieder 6, welche weitgehend isoliert in den Kästen verlaufen.The surface of the
Auf der Fahrbahnplatte 9 sind Betonleitwände 23 aufgestellt. Dadurch, dass die gesamte Oberfläche der Fahrbahnplatte 9 befahrbar ist, können die Leitwände nach Bedarf aufgestellt werden und Fahrbahnveränderungen zur Anpassung an das Verkehrsaufkommen einfach realisiert werden. Wird das Lastkollektiv erhöht, so kann durch zusätzliche Spannglieder die Tragfähigkeit der Brücke erhöht werden.On the

Die einzelnen Segmente 50, 51 werden beispielsweise mit einem Spannglied 60 aneinander gepresst. Sodann wird über die Öffnung 15 eine Vergussmasse in den Hohlraum 11 eingefüllt und damit die Segmente 50, 51 gegen Querverschiebung gesichert. Durch die Bearbeitung der Verzahnung 140 sowie der Kontaktflächen 140 bzw. Kontaktstellen 12 wird ebenfalls eine sehr exakte Positionierung der einzelnen Segmente 50, 51 zueinander bewirkt. Es werden hierdurch sehr hohe Genauigkeiten erzielt, welche mit herkömmlicher Bauweise bei Segmentfertigteilbrücken nicht erzielt werden.The

Selbstverständlich sind auch Kombinationen der Segmentfertigteilbrücken 1 und 1' möglich, bei welchen eine Teilung und Verbindung von Segmenten vorhanden ist, welche sowohl in Längs- als auch Querrichtung der Brücke verlaufen. Auch die dargestellten weiteren Details der Ausführungen der einzelnen Brücken 1 und 1' können miteinander kombiniert werden.Of course, combinations of segment prefabricated
Die vorliegende Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Abwandlungen im Rahmen der Patentansprüche sind jederzeit möglich. So kann auch die gesamte Kontaktfläche mechanisch bearbeitet werden und hierdurch eine genau passende verzahnte Profilierung geschaffen werden. Auch kann die Segmentfertigteilbrücke mit Schienen versehen sein und somit an Stelle eines Fahrbetriebes mit gummibereiften Fahrzeugen einen Betrieb mit Schienenfahrzeugen oder einen kombinierten Fahrbetrieb ermöglichen.The present invention is not limited to the illustrated embodiments. Modifications within the scope of the claims are possible at any time. Thus, the entire contact surface can be machined and thus a precisely fitting toothed profiling can be created. Also, the segment prefabricated bridge can be provided with rails and thus allow instead of a driving operation with rubber-tired vehicles operation with rail vehicles or a combined driving.
