Furthermore, methods for the production of joint profiles will be shown. On the device side, the object is achieved by devices for bridging expansion joints between two structural parts having the features of patent claims 1 and 18. Preferred embodiments of the invention are specified in the subclaims.
- a first device for bridging an expansion joint between two structural parts has at least two joint profiles for holding a stretch band or sealing strip which at least partially seals the expansion joint, which can each be fastened with an anchor construction to the relevant structural part, wherein the, preferably lying on the road surface, Joint profiles in the longitudinal direction of the joints are wave-shaped and adapted to one another in the course.
- the at least one, preferably also wave-shaped stretch band is anchored in two wave-shaped joint profiles.
- the expansion joint is waterproof, i. Water is dissipated laterally by the Dehnband and can not penetrate into the underlying areas of the expansion joint.
- the waves of the joint longitudinal profiles of the opposing should Overlay structural parts when looking in the direction of the joint longitudinal axis.
- the overlap is at least 5 mm. In this way, over the expansion joint rolling vehicle tires always have sufficient footprint.
- Another advantage is that the device, in contrast to straight, lying on the surface edge profiles can bridge a larger stretch path between the building parts and thus the maximum possible width of the expansion joint.
- the concrete connection is preferably rectilinear.
- each joint profile can be delivered to the construction site as a ready-to-install assembly and the stretch band can be buttoned in more easily and more quickly for better accessibility.
- the wave-shaped joint profile is fastened in each case by means of an anchor construction on the relevant component.
- the anchor construction may be designed as a carrier or anchor plate, which is or welded to a structural part. If the building parts are made of concrete, the anchor construction preferably has bow-shaped anchor elements which are cast into the concrete of the relevant structural part.
- the joint profiles are designed so that they at least partially overhang the expansion joint.
- At least one of the joint profiles in the vertical direction flush with the top of the associated structure part or a road surface. In this way, a continuous transition between the joint profile and the top of the building part is provided.
- the attached anchorage construction (Also referred to as anchoring structure) expediently has a straight course parallel to the expansion joint or building joint.
- the wavelength of the joint profiles i.
- the distance between two adjacent minima in the longitudinal direction of the joint is expediently not more than 600 mm. This measure ensures that a twin tire arrangement of a truck, whose width is standardized, is wider than the wavelength of the joint profile.
- the amplitude of the joint profiles i. the maximum elongation or deflection should be between 50 mm and 150 mm, preferably between 75 mm and 125 mm, more preferably 100 mm.
- wider expansion joints can be bridged.
- only expansion joint bridging arrangements are permitted for expansion joint widths of up to 80 mm.
- the expansion joint width can be increased to 150 mm, without an intermediate construction is required.
- in principle even larger expansion joint widths can be bridged.

- the amplitude and the wavelength of the wave-shaped protrusions are expediently less than the amplitude and the wavelength of the wool-shaped joint profiles. Consequently, the course of the wave-shaped joint profiles preferably follows a large primary shaft, while the course of the projections follows a smaller secondary shaft.

- At least one of the joint profiles is welded to the associated anchor construction. Through this cohesive connection, the joint profile is permanently attached to the anchor construction. Depending on the design of the welds is the Construction also waterproof, so that no moisture can penetrate into the gap between the joint profile and the anchor construction.
- At least one anchor construction can have a joint-side wave-shaped anchor plate or anchor profile to which the joint profile is fastened. This means that the joint profile is arranged on a mounting leg. The mounting leg is adapted to the joints of the contour of the joint profile. Consequently, the anchor structures can be arranged at the same height and thus particularly space-saving.
- the anchor profile can be T-shaped or L-shaped, in particular for anchoring in concrete in cross-section.

Then, namely, a horizontal mounting leg protrude into the expansion joint and wear the joint profile, while the anchoring of the overall construction is done by means of a series of anchor bracket, which can be easily mounted on the bridge. This allows a full-surface bearing of the joint profiles on the anchor construction and a good attachment of the many anchor bracket in the concrete.

- cover plates are arranged, which have adapted to each other, wavy projections, wherein the contour of the undulating projections results from an addition of a primary shaft and a secondary shaft.
- the joint profiles can be straight.
- the cover plates are preferably welded onto the joint profiles.
- the profile construction on a joint profile for holding a Dehnbandes is wavy curved and / or rolled. In the simplest case, therefore, a single joint profile forms the profile construction.
- the profile construction consists of at least one joint profile and an associated anchor construction.
- the edge profile can be delivered in the manner of a prefabricated assembly to the site, where it only needs to be attached or installed on the component.
- the joint profile is mounted on a mounting leg of an anchor structure, which has an outer edge adapted to the undulating course of the joint profile.
- the joint profile over the entire surface of the outer edge of the mounting leg rest, without protruding parts over the joint profile and into the building gap.
- the mounting leg should be aligned horizontally in an installed state, so that the joint profile can extend as possible in the vertical direction.

Description
Die Erfindung betrifft Vorrichtungen zur Überbrückung von Dehnfugen zwischen zwei Bauwerksteilen, die wenigstens zwei Fugenprofile zur Halterung eines die Dehnfuge zumindest teilweise abdichtenden Dehnbandes aufweisen, die jeweils über eine Ankerkonstruktionen an dem betreffenden Bauwerksteil befestigbar sind. Die Erfindung betrifft weiterhin eine Profilkonstruktion für eine Vorrichtung zur Überbrückung einer Dehnfuge sowie Verfahren zur Herstellung von Fugenprofilen.The invention relates to devices for bridging expansion joints between two parts of the building, which have at least two joint profiles for supporting a the expansion joint at least partially sealing tape, which are fastened in each case via an anchor structures on the relevant building part. The invention further relates to a profile construction for a device for bridging an expansion joint and to methods for producing joint profiles.

Die Fingerplattenanordnungen von Widerlager und Überbau greifen ineinander.Fingerplattenanordnung provided, which is formed flush with the adjacent bituminous layer. The Fingerplattenanordnungen of abutment and superstructure interlock.
Als nachteilig an der Lösung des zuerst genannten Dokumentes hat sich herausgestellt, dass eine gerade Fugenkante an den Bauwerksteilen von überfahrenden Fahrzeugen mit hohen Schlagkräften beaufschlagt wird, die sich in Form von Schwingungen und Störgeräuschen bemerkbar machen. Hinzu kommt die Beeinträchtigung des Fahrkomforts durch den quer verlaufenden Spalt. Dadurch begründet ist die Begrenzung des Abstandes zwischen den Fugenprofilen auf in der Regel 80 mm. Dieses Problem hat man versucht, durch die in dem zweiten Dokument genannten Fingerplattenanordnungen zu lösen. Durch die Fingerplattenanordnungen ist gewährleistet, dass ein kontinuierlicherer Lastübergang von dem einen Bauwerksteil zu dem anderen Bauwerksteil stattfindet. Das Ergebnis ist, dass wesentlich weniger Störschall erzeugt wird und wegen des verbesserten Überfahrtkomforts die Spalt weiter auf zum Beispiel maximal 100 mm vergrößert werden konnte. Der Einbau der Fingerplatten hat sich aber in der Praxis als aufwendig herausgestellt, da die Fingerplatten entsprechend genau positioniert und dann verschraubt werden müssen. Die Verschraubungen sind zudem wartungsanfällig. Ein Verschweißen der Fingerplatten ist nur bei Konstruktionen mit mehreren elastisch hintereinandergeschalteten Profilen möglich, da die Dichtprofile nur bei weit geöffneten Fugenspalten eingebaut oder ausgetauscht werden können. Es hat sich zudem gezeigt, dass die Zwischenräume zwischen den einzelnen Fingern in den Zonen, die nicht von den Fahrzeugreifen beaufschlagt werden, zu Verschmutzungen neigen, welche die Funktionsfähigkeit der Dichtungsanordnung verschlechtern und zusätzliche Wartungsarbeiten erfordern können.A disadvantage of the solution of the first mentioned document has been found that a straight joint edge is applied to the building parts of moving vehicles with high impact forces, which are noticeable in the form of vibrations and noise. Added to this is the impairment of driving comfort through the transverse gap. This justifies the limitation of the distance between the joint profiles to usually 80 mm. This problem has been tried to be solved by the Fingerplattenanordnungen mentioned in the second document. The finger plate arrangements ensure that a more continuous load transfer takes place from one structural part to the other structural part. The result is that much less noise is generated and because of the improved crossing comfort, the gap could be further increased to, for example, a maximum of 100 mm. However, the installation of the finger plates has proven to be expensive in practice, since the finger plates must be positioned according to exactly and then screwed. The glands are also maintenance-prone. A welding of the finger plates is only possible in constructions with several elastically cascaded profiles, since the sealing profiles can be installed or replaced only at wide open joint gaps. It has also been found that the spaces between the individual fingers in the zones which are not acted upon by the vehicle tires, tend to soiling, which may deteriorate the functioning of the seal assembly and may require additional maintenance.
Der Erfindung liegt daher die Aufgabe zu Grunde, Vorrichtungen zur Überbrückung von Dehnfugen und eine Profilkonstruktion aufzuzeigen, die insgesamt leichter und schneller zu montieren sind und bei denen eine derartige Verschmutzungsneigung nicht gegeben ist. Ferner sollen Verfahren zur Herstellung von Fugenprofilen aufgezeigt werden. Vorrichtungsseitig wird die Aufgabe durch Vorrichtungen zur Überbrückung von Dehnfugen zwischen zwei Bauwerksteilen mit den Merkmalen von Patentanspruch 1 und 18gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The invention is therefore based on the object to show devices for bridging expansion joints and a profile construction, which are easier and faster to assemble and in which such a tendency to fouling is not given. Furthermore, methods for the production of joint profiles will be shown. On the device side, the object is achieved by devices for bridging expansion joints between two structural parts having the features of patent claims 1 and 18. Preferred embodiments of the invention are specified in the subclaims.
Erfindungsgemäß weist eine erste Vorrichtung zur Überbrückung einer Dehnfuge zwischen zwei Bauwerksteilen wenigstens zwei Fugenprofile zur Halterung eines die Dehnfuge zumindest teilweise abdichtenden Dehnbandes bzw. Dichtbandes auf, die jeweils mit einer Ankerkonstruktion an dem betreffenden Bauwerksteil befestigbar sind, wobei die, bevorzugt an der Fahrbahnoberfläche liegenden, Fugenprofile in Fugenlängsrichtung wellenförmig und im Verlauf aneinander angepasst ausgeführt sind. Somit wird das wenigstens eine, vorzugsweise ebenfalls wellenförmig geformte Dehnband in zwei wellenförmigen Fugenprofilen verankert.According to the invention, a first device for bridging an expansion joint between two structural parts has at least two joint profiles for holding a stretch band or sealing strip which at least partially seals the expansion joint, which can each be fastened with an anchor construction to the relevant structural part, wherein the, preferably lying on the road surface, Joint profiles in the longitudinal direction of the joints are wave-shaped and adapted to one another in the course. Thus, the at least one, preferably also wave-shaped stretch band is anchored in two wave-shaped joint profiles.
Durch die wellenförmige Ausführung der Fugenprofile kann eine Abdeckung in Form von Fingerplattenanordnungen oder Lamellen eingespart werden, weil die Fugenprofile selbst einen wellenförmigen Abschluss bereitstellen. Sie übernehmen also erfindungsgemäß die Funktion der Fingerplatten selbst. Mithin kann sich kein Schmutz mehr zwischen den Bestandteilen der eingesparten Bauteile ansammeln. Weiterhin ist die Dehnfuge wasserdicht, d.h. Wasser wird durch das Dehnband seitlich abgeführt und kann nicht in die darunterliegenden Bereiche der Dehnfuge vordringen.Due to the wave-shaped design of the joint profiles, a cover in the form of finger plate arrangements or lamellas can be saved because the joint profiles themselves provide a corrugated finish. Thus, according to the invention, they assume the function of the finger plates themselves. Consequently, dirt can no longer accumulate between the components of the components saved. Furthermore, the expansion joint is waterproof, i. Water is dissipated laterally by the Dehnband and can not penetrate into the underlying areas of the expansion joint.
Ferner wird durch die wellenförmige Anordnung ein wesentlich kontinuierlicherer Übergang der Belastung zwischen den Bauwerksteilen ermöglicht, so dass bei Überfahrten der Dehnfuge mit Kraftfahrzeugen, insbesondere mit LKWs, der Störschall nochmals erheblich reduziert ist. Hierzu sollten sich die Wellen der Fugenlängsprofile der gegenüberlie-genden Bauwerksteile bei Blick in Richtung der Fugenlängsachse überlappen. Bevorzugt beträgt die Überlappung wenigstens 5 mm. Auf diese Weise haben über die Dehnfuge rollende Fahrzeugreifen stets eine ausreichende Aufstandsfläche.Furthermore, a substantially more continuous transition of the load between the structural parts is made possible by the wave-shaped arrangement, so that when crossing the expansion joint with motor vehicles, especially with trucks, the background noise is significantly reduced again. For this purpose, the waves of the joint longitudinal profiles of the opposing should Overlay structural parts when looking in the direction of the joint longitudinal axis. Preferably, the overlap is at least 5 mm. In this way, over the expansion joint rolling vehicle tires always have sufficient footprint.
Ein weiterer Vorteil ist, dass die Vorrichtung im Unterschied zu gerade verlaufenden, an der Oberfläche liegenden Randprofilen einen größeren Dehnweg zwischen den Bauwerksteilen und damit die maximal mögliche Breite der Dehnfuge überbrücken kann.Another advantage is that the device, in contrast to straight, lying on the surface edge profiles can bridge a larger stretch path between the building parts and thus the maximum possible width of the expansion joint.
Durch die Verwendung der wellenförmigen Fugenprofile kann zudem auf Verstärkungs- oder Stützrippen für den Asphaltbelag verzichtet werden, die sonst erforderlich wären, um der Ausbildung von Spurrillen im Fahrbahnbelag vorzubeugen. Der Betonanschluss ist vorzugsweise geradlinig ausgeführt.By using the wave-shaped joint profiles can also be dispensed with reinforcement or support ribs for the asphalt surface, which would otherwise be necessary to prevent the formation of ruts in the road surface. The concrete connection is preferably rectilinear.
Schließlich ist die Montage der Fugenprofile und Dichtprofile bzw. Dichtbänder einfacher, weil jedes Fugenprofil als einbaufertige Baugruppe an die Baustelle geliefert werden kann und sich das Dehnband aufgrund der besseren Zugänglichkeit leichter und schneller einknöpfen lässt.Finally, the assembly of the joint profiles and sealing profiles or sealing tapes is easier, because each joint profile can be delivered to the construction site as a ready-to-install assembly and the stretch band can be buttoned in more easily and more quickly for better accessibility.
Das wellenförmige Fugenprofil wird jeweils mittels einer Ankerkonstruktion am betreffenden Bauteil befestigt. Bei Bauwerksteilen aus Stahl, insbesondere Stahlbrücken, kann die Ankerkonstruktion als Träger oder Ankerblech ausgeführt sein, der bzw. das an einem Bauwerksteil angeschweißt ist. Sind die Bauwerksteile aus Beton, weist die Ankerkonstruktion bevorzugt bügelförmige Ankerelemente auf, die in den Beton des betreffenden Bauwerksteils eingegossen werden.The wave-shaped joint profile is fastened in each case by means of an anchor construction on the relevant component. In structural steel parts, in particular steel bridges, the anchor construction may be designed as a carrier or anchor plate, which is or welded to a structural part. If the building parts are made of concrete, the anchor construction preferably has bow-shaped anchor elements which are cast into the concrete of the relevant structural part.
Bevorzugt sind die Fugenprofile so ausgeführt, dass sie die Dehnfuge zumindest teilweise überkragen.Preferably, the joint profiles are designed so that they at least partially overhang the expansion joint.
Zweckmäßigerweise schließt wenigstens eines der Fugenprofile in vertikaler Richtung mit der Oberseite des zugehörigen Bauwerksteils oder einem Fahrbahnbelag bündig ab. Auf diese Weise wird ein kontinuierlicher Übergang zwischen dem Fugenprofil und der Oberseite des Bauwerksteils bereitgestellt. Die daran angeschlossene Ankerungskonstruktion (auch als Verankerungskonstruktion bezeichnet) weist zweckmäßigerweise einen geraden Verlauf parallel zur Dehnfuge bzw. Bauwerksfuge auf.Conveniently, at least one of the joint profiles in the vertical direction flush with the top of the associated structure part or a road surface. In this way, a continuous transition between the joint profile and the top of the building part is provided. The attached anchorage construction (Also referred to as anchoring structure) expediently has a straight course parallel to the expansion joint or building joint.
Die Wellenlänge der Fugenprofile, d.h. der Abstand zwischen zwei benachbarten Minima in Fugenlängsrichtung, beträgt zweckmäßigerweise maximal 600 mm. Diese Maßnahme stellt sicher, dass eine Zwillingsreifenanordnung eines LKWs, deren Breite genormt ist, breiter als die Wellenlänge des Fugenprofils ist.The wavelength of the joint profiles, i. The distance between two adjacent minima in the longitudinal direction of the joint is expediently not more than 600 mm. This measure ensures that a twin tire arrangement of a truck, whose width is standardized, is wider than the wavelength of the joint profile.
Die Amplitude der Fugenprofile, d.h. die maximale Elongation bzw. Auslenkung, sollte zwischen 50 mm und 150 mm, vorzugsweise zwischen 75 mm und 125 mm, weiter bevorzugt 100 mm, betragen. Mithin lassen sich breitere Dehnfugen Überbrücken. Derzeit sind nur Dehnfugenüberbrückungsanordnungen für Dehnfugenbreiten von bis zu 80 mm zugelassen. Bei größeren Dehnfugen sind bislang Mittelprofile oder Lamellenaanordnungen bzw. Traversen zwingend vorzusehen. Mit der erfindungsgemäßen Vorrichtung kann die Dehnfugenbreite auf 150 mm vergrößert werden, ohne dass eine Zwischenkonstruktion erforderlich ist. Abhängig von Wellenlänge und Amplitude des Fugenprofils sind prinzipiell sogar noch größere Dehnfugenbreiten überbrückbar.The amplitude of the joint profiles, i. the maximum elongation or deflection should be between 50 mm and 150 mm, preferably between 75 mm and 125 mm, more preferably 100 mm. Thus, wider expansion joints can be bridged. At present, only expansion joint bridging arrangements are permitted for expansion joint widths of up to 80 mm. For larger expansion joints so far center profiles or Lamellenaanordnungen or traverses are mandatory. With the device according to the invention, the expansion joint width can be increased to 150 mm, without an intermediate construction is required. Depending on the wavelength and amplitude of the joint profile, in principle even larger expansion joint widths can be bridged.
Besonders vorteilhaft ist es, wenn eines der Fugenprofile einstückig ausgeführt ist. Auf diese Weise kann es z.B. im Strangguss- oder Walzverfahren bei gleichzeitiger oder nachträglicher wellenförmigen Verformung rationell hergestellt werden.It is particularly advantageous if one of the joint profiles is made in one piece. In this way it can e.g. be produced efficiently in the continuous casting or rolling process with simultaneous or subsequent wave-shaped deformation.
Das Fugenprofil kann jedoch auch mehrteilig ausgeführt sein. Insbesondere kann das Fugenprofil einen bevorzugt vertikalen, wellenförmigen Steg aufweisen, auf dem ein wellenförmiges Deckblech angeordnet ist. Bei einer mehrteiligen Anordnung kann der Steg aus einer Vielzahl von bogenförmigen Stegabschnitten zusammengesetzt sein. Das Deckblech kann in einem Stück aus einer Platte ausgeschnitten sein. Das Profil wird also aus flachen Blechen zusammengesetzt, die jeweils leicht in die entsprechende Form gebracht werden können, der Steg durch Biegen, das Deckblech durch Zuschneiden.However, the joint profile can also be designed in several parts. In particular, the joint profile may have a preferably vertical, wavy web on which a wave-shaped cover plate is arranged. In a multi-part arrangement, the web can be composed of a plurality of arcuate web portions. The cover plate can be cut in one piece from a plate. The profile is thus composed of flat sheets, which can each be easily brought into the appropriate shape, the bridge by bending, the cover plate by cutting.
Vorzugsweise ist ein Fugenprofil im Querschnitt F- oder Y-förmig zur Halterung eines Dehnbandes ausgeführt. Die das Dehnband aufnehmenden Schenkel sollten dabei in vertikaler Richtung nach innen kragend ausgeführt sein um eine zuverlässige Halterung des Dehnbandes am Fugenprofil zu gewährleisten.Preferably, a joint profile in cross-section F- or Y-shaped designed to hold a Dehnbandes. The stretch band receiving legs should be executed in the vertical direction inwardly cantilevered to ensure a reliable support of the Dehnbandes at the joint profile.
Die wellenförmigen Fugenprofile können im Kopfbereich wellenförmige Auskragungen aufweisen. Durch diese Maßnahme kann der Spalt zwischen den Bauwerksteilen im Gegensatz zum Dehnweg nochmals verbreitert werden. Die Auskragungen stellen eine Überlappung der Fugenprofile sicher, so dass stets eine ausreichende Aufstandsfläche für über die Dehnfuge rollende Fahrzeugreifen bereitgestellt wird.The wave-shaped joint profiles may have wave-shaped protrusions in the head area. By this measure, the gap between the building parts in contrast to the extension can be widened again. The projections ensure an overlap of the joint profiles, so that a sufficient footprint is always provided for rolling over the expansion joint vehicle tires.
Die Amplitude und die Wellenlänge der wellenförmigen Auskragungen sind zweckmäßiger Weise geringer als die Amplitude und die Wellenlänge der wollenförmigen Fugenprofile. Mithin folgt der Verlauf der wellenförmigen Fugenprofile bevorzugt einer großen Primärwelle, während der Verlauf der Auskragungen einer kleineren Sekundärwelle folgt.The amplitude and the wavelength of the wave-shaped protrusions are expediently less than the amplitude and the wavelength of the wool-shaped joint profiles. Consequently, the course of the wave-shaped joint profiles preferably follows a large primary shaft, while the course of the projections follows a smaller secondary shaft.
Auf die Fugenprofile können Deckplatten aufgeschweißt sein, welche die wellenförmigen Auskragungen aufweisen. Mithilfe der Deckplatten lassen sich die Auskragungen leichter ausbilden. Sie sind zudem montagefreundlicher.On the joint profiles cover plates can be welded, which have the undulating projections. The cover plates make the projections easier to form. They are also easier to install.
In die Fugenprofile kann ein Dehnband zum Beispiel aus Elastomer eingeknöpft sein. Das Dehnband kann randseitige Verdickungen aufweisen, die an den Hinterschneidungen des F-förmigen Fugenprofils rastend zur Anlage gelangen. Auf diese Weise wird eine dauerhaft sichere und einfache Halterung des Dehnbandes am Fugenprofil bereitgestellt. Besonders bei den oben genannten Wellenabmessungen ist es möglich, ein Dehnband aus Gummi zu verwenden, das wie herkömmlich gerade ist und das erst durch den Einbau in die Wellenform gebracht wird.In the joint profiles, a stretch band can be buttoned, for example made of elastomer. The Dehnband may have edge thickening, which reach the undercuts of the F-shaped joint profile latching to the plant. In this way, a permanently secure and easy mounting of the stretch tape is provided on the joint profile. Especially with the shaft dimensions mentioned above, it is possible to use a rubber stretch band which is as conventional straight and which is brought into the waveform only by the installation.
Besonders zweckmäßig ist es, wenn wenigstens eines der Fugenprofile mit der zugeordneten Ankerkonstruktion verschweißt ist. Durch diese stoffschlüssige Verbindung wird das Fugenprofil an der Ankerkonstruktion dauerhaft befestigt. Je nach Ausführung der Schweißnähte ist die Konstruktion auch wasserdicht, so dass keine Feuchtigkeit in den Spalt zwischen dem Fugenprofil und der Ankerkonstruktion eindringen kann. Wenigstens eine Ankerkonstruktion kann ein fugenseitig wellenförmiges Ankerblech oder Ankerprofil aufweisen, an dem das Fugenprofil befestigt ist. Das heißt, dass das Fugenprofil an einem Befestigungsschenkel angeordnet ist. Der Befestigungsschenkel ist fugenseitig an die Kontur des Fugenprofils angepasst. Mithin können die Ankerkonstruktionen auf gleicher Höhe und damit besonders bauraumsparend angeordnet werden.It is particularly expedient if at least one of the joint profiles is welded to the associated anchor construction. Through this cohesive connection, the joint profile is permanently attached to the anchor construction. Depending on the design of the welds is the Construction also waterproof, so that no moisture can penetrate into the gap between the joint profile and the anchor construction. At least one anchor construction can have a joint-side wave-shaped anchor plate or anchor profile to which the joint profile is fastened. This means that the joint profile is arranged on a mounting leg. The mounting leg is adapted to the joints of the contour of the joint profile. Consequently, the anchor structures can be arranged at the same height and thus particularly space-saving.
Das Ankerprofil kann insbesondere zur Verankerung in Beton im Querschnitt T- oder L-förmig sein. Diese Form hat sich als optimal zur effizienten Kraftübertragung der auf das Fugenprofil wirkenden Lasten der Fahrzeuge in die Bauwerksteile erwiesen. Dann kann nämlich ein horizontaler Befestigungsschenkel in die Dehnfuge hineinragen und das Fugenprofil tragen, während die Verankerung der Gesamtkonstruktion mittels einer Reihe von Ankerbügel erfolgt, die gut am Steg angebracht werden können. Dies ermöglicht eine vollflächige Auflage der Fugenprofile auf der Ankerkonstruktion und eine gute Befestigung der vielen Ankerbügel im Beton.The anchor profile can be T-shaped or L-shaped, in particular for anchoring in concrete in cross-section. This form has proven to be optimal for the efficient transmission of forces acting on the joint profile loads of vehicles in the building parts. Then, namely, a horizontal mounting leg protrude into the expansion joint and wear the joint profile, while the anchoring of the overall construction is done by means of a series of anchor bracket, which can be easily mounted on the bridge. This allows a full-surface bearing of the joint profiles on the anchor construction and a good attachment of the many anchor bracket in the concrete.
Vorzugsweise ist wenigstens eines der Fugenprofile über eine wellenförmig auskragende Ankerkonsole an einem Stahlquerträger eines Bauwerksteiles insbesondere eines Stahlbauwerks festgelegt.Preferably, at least one of the joint profiles is fixed via a wave-shaped projecting anchor bracket to a steel cross member of a structural part, in particular a steel structure.
Zwischen den Fugenprofilen kann eine Zwischenkonstruktion vorgesehen sein, die ein wellenförmiges Fugenprofil aufweist. Zur Überbrückung von größeren Spalten werden zum Beispiel auf Traversen verschiebbar angeordnete Mittelträger oder Lamellen bzw. Mittelprofile zwischen den Bauwerksteilen angeordnet. Der Mittelträger oder die Mittelprofile beziehungsweise die Lamellen können wellenförmig ausgebildet sein. Diese Zwischenkonstruktionen können weiterhin an den den angrenzenden Bauwerkstellen zugewandten Seiten Fugenprofile aufweisen. Somit kann eine breitere Dehnfuge mit den wellenförmigen Fugenprofilen auf besonders vorteilhafte Weise überbrückt werden. Der Störschall, der beim Überfahren dieser Vorrichtung entsteht, ist geringer als bei herkömmlichen Lammellenkonstruktionen. Hinzu kommt die Aufnahme größerer Dehnwege je Einzelspalt. Eine derartige Konstruktion kann als Alternative zu der zum Beispiel in der
Gemäß einer weiteren Lösung der Aufgabe weist eine zweite Vorrichtung zur Überbrückung einer Dehnfuge zwischen zwei Bauwerksteilen wenigstens zwei Fugenprofile zur Halterung eines die Dehnfuge zumindest teilweise abdichtenden Dehnbandes auf, die jeweils mit einer Ankerkonstruktion an dem betreffenden Bauteil befestigbar sind. Auf den Fugenprofilen sind Deckplatten angeordnet, die aneinander angepasste, wellenförmige Auskragungen aufweisen, wobei sich die Kontur der wellenförmigen Auskragungen aus einer Addition einer Primärwelle und einer Sekundärwelle ergibt. Bei dieser Lösung können die Fugenprofile gerade ausgeführt sein. Die Deckplatten sind vorzugsweise auf die Fugenprofile aufgeschweißt. Der besondere Vorteil dieser Lösung ist, dass die Doppelwellen mit Deckplatten erzeugt werden, die mit modernen Schneidmaschinen besonders rationell herstellbar sind.According to a further solution of the problem, a second device for bridging an expansion joint between two structural parts on at least two joint profiles for holding a the expansion joint at least partially sealing tape, which are each fastened with an anchor construction on the relevant component. On the joint profiles cover plates are arranged, which have adapted to each other, wavy projections, wherein the contour of the undulating projections results from an addition of a primary shaft and a secondary shaft. In this solution, the joint profiles can be straight. The cover plates are preferably welded onto the joint profiles. The particular advantage of this solution is that the double shafts are produced with cover plates, which can be produced particularly efficiently with modern cutting machines.
Gemäß Patentanspruch 18 weist die Profilkonstruktion ein Fugenprofil zur Halterung eines Dehnbandes auf. Erfindungsgemäß ist das Fugenprofil wellenförmig gebogen und/oder gewalzt. Im einfachsten Fall bildet also ein einzelnes Fugenprofil die Profilkonstruktion.According to claim 18, the profile construction on a joint profile for holding a Dehnbandes. According to the joint profile is wavy curved and / or rolled. In the simplest case, therefore, a single joint profile forms the profile construction.
Besonders vorteilhaft ist es, wenn die Profilkonstruktion aus wenigstens einem Fugenprofil und einer damit verbundenen Ankerkonstruktion besteht. So kann das Randprofil in der Art einer vorgefertigten Baugruppe an die Baustelle geliefert werden, wo sie nur noch am Bauteil befestigt bzw. eingebaut werden muss.It is particularly advantageous if the profile construction consists of at least one joint profile and an associated anchor construction. Thus, the edge profile can be delivered in the manner of a prefabricated assembly to the site, where it only needs to be attached or installed on the component.
Bevorzugt ist das Fugenprofil auf einem Befestigungsschenkel einer Ankerkonstruktion befestigt, der eine an den wellenförmigen Verlauf des Fugenprofils angepasst Außenkante aufweist. So kann das Fugenprofil vollflächig an der Außenkante des Befestigungsschenkels anliegen, ohne dass Teile über das Fugenprofil und in den Bauwerkspalt hinein ragen. Der Befestigungsschenkel sollte in einem eingebauten Zustand horizontal ausgerichtet sein, damit sich das Fugenprofil möglichst in vertikaler Richtung erstrecken kann.Preferably, the joint profile is mounted on a mounting leg of an anchor structure, which has an outer edge adapted to the undulating course of the joint profile. Thus, the joint profile over the entire surface of the outer edge of the mounting leg rest, without protruding parts over the joint profile and into the building gap. The mounting leg should be aligned horizontally in an installed state, so that the joint profile can extend as possible in the vertical direction.
Der Befestigungsschenkel ist vorteilhafterweise ein Teil eines T- oder L-förmigen Ankerprofils der Ankerkonstruktion. Die T-Form hat sich gerade für die Verankerung in Beton als besonders geeignete Bauform der Ankerkonstruktion herausgestellt. So kann der horizontale Befestigungsschenkel in die Dehnfuge hineinragen und eine Auflage für das Fugenprofil ausbilden, während der Steg eine gute Befestigungs-möglichkeit für die bevorzugt bügelförmig ausgebildeten Ankerelemente schafft. Dadurch kann ein einfacher Anschluss der Verankerung an dem üblicherweise gerade verlaufenden Bauwerksabschluss und bei Betonbauwerken eine saubere Schalung hergestellt werden.The attachment leg is advantageously part of a T- or L-shaped anchor profile of the anchor construction. The T-shape has proven to be an especially suitable design of the anchor construction for anchoring in concrete. Thus, the horizontal attachment leg protrude into the expansion joint and form a support for the joint profile, while the web provides a good attachment possibility for the preferably bow-shaped anchor elements. As a result, a simple connection of the anchorage to the usually straight building completion and concrete structures in a clean formwork can be made.
Bei Stahlbauwerken kann der horizontale Befestigungsschenkel auf unterschiedlich weit auskragende Scheiben gestützt sein, die mit einem gerade verlaufenden Endquerträger verbunden sind.In steel structures, the horizontal mounting leg can be supported on different far projecting discs, which are connected to a straight end cross member.
Das Fugenprofil selbst sollte krallenförmige Auskragungen zur Halterung eines Dehnbandes aufweisen. Dann kann das Dichtprofil formschlüssig mit Hilfe von Verdickungen am Fugenprofil befestigt werden.The joint profile itself should have claw-shaped protrusions for holding a Dehnbandes. Then the sealing profile can be positively secured by means of thickening of the joint profile.
Der nach oben bündig mit der Oberseite des Bauwerks abschließende Teil der wellenförmigen Fugenprofile kann aus einem korrosionsbeständigen Werkstoff, zum Beispiel Edelstahl, ausgeführt und mit einem darunterliegenden Teil aus normalem Baustahl verbunden werden. Derartige Hybridträger sind besonders langlebig, da der Korrosionsschutz an den exponierten Teilen häufig beschädigt wird.The upward flush with the top of the building final part of the wave-shaped joint profiles can be made of a corrosion-resistant material, for example stainless steel, and connected to an underlying part of normal structural steel. Such hybrid carriers are particularly durable, since the corrosion protection is often damaged on the exposed parts.
Gemäß Anspruch 1 ist das Fugenprofil bei mehrteiliger Ausführung zumindest teilweise und bei einstückiger Ausführung insgesamt mit einem Heißformverfahren oder einem Kaltformverfahren wellenförmig gepresst, gewalzt und/oder gebogen.In accordance with claim 1, the joint profile in the case of a multi-part design is pressed, rolled and / or bent at least partially and in the case of a one-piece design as a whole with a hot-forming process or a cold-forming process.
