Description

Die Erfindung betrifft eine Dichtungsvorrichtung zum Abdichten von Betonfugen.The invention relates to a sealing device for sealing of concrete joints.

Es ist bekannt zum Abdichten von Fugen, die sich zwischen zwei aneinanderliegenden Stoßflächen zweier Betonierabschnitte bilden, Blechstreifen zu verwenden.It is known for sealing joints that are between two form adjacent abutting surfaces of two concreting sections, Use metal strips.

Diese Blechstreifen werden vor dem Betonieren des ersten Betonierabschnittes an einer im Betonierabschnitt angeordneten Bewehrung mit Rödeldraht oder dergleichen befestigt, oder in entsprechend geformte Aufnahmeschlitze an der Bewehrung eingesetzt, so daß der Blechstreifen etwa senkrecht und in etwa symmetrisch zu den sich bildenden Stoßflächen angeordnet ist. Der Blechstreifen wird dann in die Betonierabschnitte eingegossen, so daß er die Fuge versperrt und das Eindringen von Feuchtigkeit durch die Fuge hindurch verhindert.These sheet metal strips are made before concreting the first concreting section on a reinforcement arranged in the concreting section attached with string wire or the like, or in accordance shaped receiving slots used on the reinforcement, so that the metal strip is approximately vertical and approximately symmetrical is arranged to the abutting surfaces. The metal strip is then poured into the concreting sections so that he blocked the joint and the penetration of moisture through prevented the joint.

Die Blechstreifen werden üblicherweise mit einer Breite von 300 mm oder größer und einer Stärke von 3 bis 4 mm verwendet. Die einzelnen Blechstreifen werden in einer Werkstatt zugeschnitten und vorgeformt und auf der Baustelle durch Schweißen und Löten miteinander verbunden. Ein nicht korrekt vorgefertigter Blechstreifen kann nicht ohne weiteres auf der Baustelle umgearbeitet werden, weshalb sich bei unkorrekter Vorbereitung der Blechstreifen das Setzen der Betonierabschnitte durch eine erneute Werkstattbearbeitung stark verzögern kann. Die Blechstreifen sind korrosionsanfällig, es sei denn, daß rostfreies Blech verwendet wird, das sich aber mit dem Beton nicht gut verbindet. Für eine gute Verbindung zwischen dem Blechstreifen und dem Beton werden deshalb vorzugsweise mit Flugrost besetzte Blechstreifen verwendet, da hierdurch eine bessere Verbindung zwischen Blech und Beton erreicht wird. Ein korrodierender Blechstreifen ist jedoch auf Dauer gefährlich, da ein Durchrosten nicht ausgeschlossen werden kann. Ferner haben die Blechstreifen aufgrund ihrer Stärke und Breite ein erhebliches Gewicht, wodurch zum Anheben und Umsetzen eines für einen längeren Bauabschnitt zusammengesetzten Blechstreifens ein Kraneinsatz notwendig sein kann. Ferner werden Blechstreifen nur in Form von ebenflächigen Elementen verwendet, da eine besondere Raumform mit beträchtlichen Kosten verbunden ist.The sheet metal strips are usually 300 in width mm or larger and a thickness of 3 to 4 mm is used. The individual metal strips are cut in a workshop and preformed and on site by welding and soldering connected with each other. An incorrectly prefabricated sheet metal strip cannot easily be remodeled on site which is why if the sheet metal strip is incorrectly prepared the setting of the concreting sections by a new one Workshop processing can greatly delay. The metal strips are susceptible to corrosion unless stainless steel is used that does not bond well with the concrete. For a good connection between the metal strip and the Concrete is therefore preferably sheet metal strips covered with flash rust used because this creates a better connection between Sheet metal and concrete is reached. A corroding sheet of metal is dangerous in the long run, however, because rusting through cannot be excluded. Furthermore, the sheet metal strips due to their strength and width, a considerable weight, which makes for lifting and moving one for a longer construction phase composite sheet metal strip a crane is necessary can be. Furthermore, metal strips are only in the form of flat surfaces Used elements because of a special spatial shape considerable cost.

Die durch Schweißen oder Löten miteinander verbundenen Blechstreifenplatten sind an ihren Nahtstellen besonderes korrosionsanfällig, die eine erhebliche Gefahrenquelle für Undichtigkeiten darstellen.The sheet metal strip plates joined together by welding or soldering are particularly susceptible to corrosion at their seams, which is a significant source of danger for leaks represent.

Vorteilhaft an den Blechstreifen ist, daß sie nicht notwendigerweise vor dem ersten Betoniervorgang gesetzt werden müssen, sondern auch kurz nach dem Vergießen des ersten Betonierabschnitts in den noch zähflüssigen Beton eingedrückt werden können. Hierbei sollte der Beton jedoch im Bereich des Blechstreifens nachverdichtet werden, um eine ausreichende Verbindung zwischen Beton und Blechstreifen und damit eine ausreichende Dichtigkeit sicherzustellen.The advantage of the metal strips is that they are not necessarily must be set before the first concreting process, but also shortly after pouring the first concrete section can be pressed into the viscous concrete. Here, however, the concrete should be in the area of the metal strip be densified to an adequate connection between concrete and sheet metal strips and thus an adequate Ensure tightness.

Zusammenfassend ist festzustellen, daß die Blechstreifen zwar einfach an der Bewehrung befestigt oder nachträglich in den noch zähflüssen Beton eingedrückt werden können, jedoch ihre Handhabung beim Zuschneiden, Biegen und Zusammenfügen aufwendig ist, und daß sie insbesondere aufgrund ihrer Korrodierbarkeit eine erhebliche Gefahr für Undichtigkeiten darstellen. In summary it can be stated that the sheet metal strips simply attached to the reinforcement or later in the viscous concrete can be dented, but their handling cutting, bending and assembling is complex, and that they have a particular corrodibility pose a significant risk of leaks.

Zur Abdichtung einer Fuge zwischen zwei Stoßflächen zweier Betonierabschnitte werden auch Fugenbänder aus Elastomermaterial verwendet. Für eine wirksame Abdichtung ist der Querschnitt der Fugenbänder nach dem Labyrinthprinzip ausgebildet, wobei die Fugenbänder mit im Querschnitt trapezförmigen oder dreieckigen Riefen versehen sind, die eine Verlängerung des Wasserweges bei gleichzeitigem Druckabbau bewirken.For sealing a joint between two abutting surfaces of two concreting sections are also joint tapes made of elastomer material used. The cross-section is for effective sealing Joint tapes formed on the labyrinth principle, the Joint tapes with a trapezoidal or triangular cross section Grooves are provided that extend the waterway cause simultaneous pressure reduction.

Für die Erfüllung ihrer Funktion ist ein sachgemäßer Einbau der Fugenbänder Voraussetzung, insbesondere ist ein direkter Anschluß an den Beton herzustellen. Die größte Beanspruchung eines Fugenbandes tritt beim Einbau auf, weshalb große Anstrengungen unternommen werden müssen, um in dieser Phase örtliche Überbeanspruchungen durch Dehnung, Knicken und Quetschen zu vermeiden. So dürfen die Fugenbänder, außer an schmalen äußeren Randstreifen, die nur für diesen Zweck vorgesehen sind, nicht genagelt werden. Besonders ist darauf zu achten, daß die elastischen Fugenbandschenkel nicht umklappen und Taschen im Beton bilden, die nachträglich kaum noch gedichtet werden können. Hierdurch können sich insbesondere Hohlräume, poröse Stellen oder Nuten bilden, die dem Wasser einen Weg zur Umgehung des Fugenbandes öffnen. Deshalb ist es notwendig, Fugenbänder in relativ kurzen Abständen an den in den Betonierabschnitten vorgesehenen Bewehrungen zu befestigen, so daß ein Umklappen sicher vermieden wird. Eine ausreichende Dichtigkeit wird nur erreicht, wenn die Fugenbänder in den Beton eingebettet sind. Die Schenkel horizontal verlaufender Fugenbänden sollten unter einem Winkel von etwa 15° hochgezogen werden, um Lufteinschlüsse im Beton an der Unterseite der Fugenbänder zu vermeiden.Proper installation is essential for the fulfillment of their function Joint tapes Requirement, in particular a direct connection is required to manufacture the concrete. The greatest stress of a Joint tape occurs during installation, which is why great effort must be undertaken to deal with local overuse during this phase to avoid by stretching, kinking and squeezing. The joint tapes, except on narrow outer edge strips, may which are only intended for this purpose, not nailed become. It is particularly important to ensure that the elastic Do not fold the joint tape legs and form pockets in the concrete, which can hardly be sealed afterwards. Hereby can especially cavities, porous spots or grooves form the water a way to bypass the joint tape to open. That is why it is necessary to use joint tapes in relatively short Clearances at the reinforcements provided in the concreting sections to fasten so that folding is avoided becomes. Adequate tightness is only achieved if the Joint tapes are embedded in the concrete. The thighs horizontal running joint tapes should be at an angle of about 15 ° to raise air pockets in the concrete at the bottom to avoid the joint tapes.

Die Fugenbänder werden als Rollenware an die Baustelle geliefert und können durch ihre Biegsamkeit einfach dem Fugenverlauf angepaßt werden. Sie werden an der Baustelle zugeschnitten und durch Vulkanisieren miteinander verbunden. Die Vulkanisierung wird mit speziellen Vulkanisiergeräten durch Zugabe von Rohmaterial unter Druck und Wärme ausgeführt. Jedoch können auf der Baustelle nur gerade Verbindungen hergestellt werden, weshalb große Teilsysteme, in denen Abschnitte der Fugenbänder eines ganzen Bauabschnittes mit allen Kreuzungen und Abzweigungen zusammengefaßt sind, vorgefertigt an die Baustelle geliefert werden. Es gibt zwar Sätze von rechtwinkligen Formteilen, die aber im allgemeinen nicht für ein komplettes Abdichtungssystem ausreichen, weshalb die konstruktive Bearbeitung von Fugenband-Formteilen frühzeitig bei der Entwurfserstellung zu berücksichtigen ist.The joint tapes are delivered to the construction site as rolls and can be easily adapted to the course of the joint due to their flexibility become. They are cut and cut at the construction site Vulcanizing linked together. The vulcanization comes with special vulcanizing equipment by adding raw material under Executed pressure and heat. However, on site only straight connections are being made, which is why large subsystems, in which sections of the joint tapes of an entire construction section summarized with all intersections and branches are ready to be delivered to the construction site. There are sets of rectangular moldings, but in general not sufficient for a complete sealing system, which is why the constructive processing of joint tape molded parts at an early stage is to be considered when drafting.

Zusammenfassend ist somit festzustellen, daß die Fugenbänder bei einfachen geradlinigen bzw. rechtwinkligen Bauabschnitten auf der Baustelle bearbeitet werden können, jedoch muß bei komplizierteren Baumaßnahmen vorausschauend geplant und Fugenband-Formteile müssen vorgefertigt werden. Zudem ist ein beträchtlicher Aufwand beim Befestigen des Fugenbandes an der Bewehrung notwendig bzw. besteht bei nicht ordnungsgemäßer Befestigung die Gefahr, daß das Fugenband umklappt, wodurch Hohlräume, poröse Stellen oder Nester verursacht werden.In summary, it can be stated that the joint tapes at simple straight or right-angled sections the construction site can be edited, but must be more complicated Construction measures planned in advance and joint tape fittings must be prefabricated. It is also a considerable one Effort when attaching the joint tape to the reinforcement necessary or exists if the attachment is incorrect Danger that the joint tape folds over, creating voids, porous Spots or nests.

Um die letztgenannten arbeitstechnischen Probleme zu beseitigen, sind Fugenbänder mit seitlichen Blechstreifen entwickelt worden, bei denen der Blechstreifen in das Fugenband einvulkanisiert ist. Derartige Fugenbänder sind jedoch aufwendig und deshalb teuer und weisen bei der Handhabung die selben Probleme, wie die eingangs diskutieren Blechstreifen auf. Ferner ist es bekannt, an beiden Längsseitenkanten der an die Fugenbänder angeformten Blechstreifen jeweils einen Injektionsschlauch anzubringen, der das nachträgliche Einbringen von Dichtmaterial in den Fugenbereich ermöglichen. Das Injizieren von Dichtmaterial muß beidseitig erfolgen, um die beiden Wasserwege um die Längsseitenkanten jeweils abzuschneiden. In order to eliminate the latter technical problems, joint tapes with lateral metal strips have been developed, where the sheet metal strip is vulcanized into the joint tape is. Such joint tapes are complex and therefore expensive and have the same handling problems as that initially discuss sheet metal strips. It is also known on both longitudinal edges of the molded on the joint tapes Attach an injection hose to each of the metal strips the subsequent introduction of sealing material into the joint area enable. The injection of sealing material must be on both sides take place around the two waterways around the long edges cut off each.

Aus der DE-A-40 25 599 ist eine Dichtungsgarnitur zum dichten Verbinden zweier Bauelemente bekannt.From DE-A-40 25 599 is a sealing set for sealing Connecting two components known.

Diese Dichtungsgarnitur besteht aus einem weitgehend biegesteifen oder starren Verbindungsteil und aus wenigstens einem elastomeren Dichtungsteil, der im Bereich des am axialen Endabschnnitt des Verbindungsteils befindlichen Vorsprunges angeordnet ist. Der axiale Endabschnnitt des Verbindungsteils wird in einem, in ein Bauelement eingebrachten Dichtspalt eingeschoben, wobei der elastomere Dichtungsteil, der an dem starren Verbindungsteil angeordnet ist, für eine dichte Fuge sorgen soll.This sealing set consists of a largely rigid or rigid connecting part and made of at least one elastomer Sealing part in the area of the axial end section of the connecting part located projection is. The axial end section of the connecting part is inserted into a component sealing gap, wherein the elastomeric sealing part, which on the rigid connecting part is arranged to ensure a tight joint.

Bei einer solchen Dichtungsgarnitur zum dichten Verbinden zweier Bauelemente ist von Nachteil, daß sich mit dieser Dichtungsgarnitur nur vorgefertigte, mit Nuten versehene Bauelemente zu dichten Wänden zusammemstecken lassen. Darüber hinaus ist von Nachteil, daß aufgrund der zwei Komponenten Ausbildung dieses Bauteils, d.h. einem starren Verbindungsteil aus einem Kunststoff und einem elastomeren Dichtungsteil aus einem anderen Kunststoff nicht ohne weiteres am Anwendungsort beliebige Formen der Dichtungsgarnitur, beispielsweise mittels Verschweißung, erreichen lassen Das Verschweißen oder Warmumformen von Kunststoffen gelingt im allgemeinen nur, wenn eine einzige Kunststoffsorte verwendet wird.With such a sealing set for the tight connection of two Components is disadvantageous that with this seal set only prefabricated, grooved components put together tight walls. In addition, from Disadvantage that due to the two components training this Component, i.e. a rigid connecting part made of a plastic and an elastomeric sealing member made of another Plastic not just any shape at the place of use the sealing set, for example by welding The welding or hot forming of plastics generally only succeeds if a single type of plastic is used.

Ferner ist in der EP 0 418 699 A1 eine Dichtungsvorrichtung zum Einspritzen von Dichtmaterial in den Fugenbereich beschrieben, die aus einem im Querschnitt offenen, haubenförmig ausgebildeten Profil besteht, welches mit den freien Längskanten seiner Seitenbereiche auf einer Betonoberfläche aufsitzend montiert wird, so daß ein Durchflußkanal für das Dichtmaterial zwischen dem Profil und der Betonoberfläche gebildet wird. Das Dichtmaterial wird unter hohem Druck in den Durchflußkanal eingeführt und tritt zwischen den freien Längskanten des Profils an der Betonoberfläche an Fehlstellen des Betons aus. Eine weitere darin beschriebene Dichtungsvorrichtung besteht aus einem Körper, der aus einem Duchgangsporen aufweisenden Schaumstoff bzw. Schaumstoffband, vorzugsweise mit rechteckigem Querschnitt besteht, welcher auf der Betonoberfläche aufliegend montiert wird, so daß der Durchflußkanal für ein Dichtmaterial durch den Körper selbst gebildet wird, wobei das Dichtmaterial aus den Durchgangsporen in den Fugenbereich austritt.Furthermore, EP 0 418 699 A1 describes a sealing device for Injecting sealing material into the joint area described those made of a hood-shaped, open cross-section Profile exists, which with the free longitudinal edges of its side areas mounted on a concrete surface, so that a flow channel for the sealing material between the Profile and the concrete surface is formed. The sealing material is introduced into the flow channel under high pressure and occurs between the free longitudinal edges of the profile on the concrete surface defects in the concrete. Another in it Sealing device described consists of a body that from a foam or foam tape with passage pores, preferably has a rectangular cross section, which is mounted on the concrete surface, so that the flow channel for a sealing material through the body itself is formed, the sealing material from the through pores emerges in the joint area.

Weiterhin sind Dichtungsschläuche bekannt, die beispielsweise in der CH-PS 600 077 beschrieben sind, die aus einem Stützkörper in Form einer Schraubenfeder bestehen, der von einem ersten, geflochtenen Injektionsschlauch umgeben ist, der wiederum von einem äußeren, netzartigen porösen Schlauch umfaßt ist. Nach dem Montieren dieser Schläuche und dem Betonieren des zweiten Betonierabschnittes wird ein Dichtmaterial in die schlauchartige Dichtungsvorrichtung gepreßt, das an Fehlstellen des Betons austreten soll.Sealing hoses are also known, for example in the CH-PS 600 077 are described, which from a support body in Form of a coil spring consist of a first, braided Injection hose is surrounded, which in turn by an outer, mesh-like porous tube is included. After this Assemble these hoses and concreting the second concreting section becomes a sealing material in the hose-like Sealing device pressed, the missing parts of the concrete should exit.

Ferner werden zum Abdichten von Betonfugen auch Quellbänder verwendet, die unter Wassereinfluß aufquellen, das Quellmittel ist eine hydrophile Masse, die in einem Trägerstoff, meist Chloropren-Gummi, eingebettet ist. Der Trägerstoff hat vor allem die Aufgabe, dem Quellmittel Stabilität und Elastizität zu verleihen. Die hydrophile (wassersaugende-) Komponente nimmt Wassermoleküle auf und vergrößert dadurch ihr Volumen um das 1,5 bis ca. 4-fache. Dabei entsteht ein Druck bis zu 6,5 bar, der die umgebenden Hohlräume ausfüllt und dadurch wasserundurchlässig machen soll. Bei Verwendung derartiger Quellmittel ist zu berücksichtigen, daß sich die Quellmasse nicht plötzlich, sondern über Stunden oder Tage langsam ausdehnt und demzufolge in Wechselbereichen mit nassen und trockenen Perioden nur beschränkt verwendet werden kann. Ein markanter Vorteil von Quellbändern, weshalb sie häufig eingesetzt werden, liegt in deren Möglichkeit, Fugen zwischen unterschiedlichen Materialien wie z.B. Beton, Kunststoff, Beton/Eisen usw., zuverlässig abzudichten.Furthermore, swelling tapes are also used to seal concrete joints used that swell under the influence of water, the swelling agent is a hydrophilic mass contained in a carrier, usually chloroprene rubber, is embedded. The carrier has above all that Task to give the swelling agent stability and elasticity. The hydrophilic (water-absorbing) component takes water molecules and thereby increases their volume by 1.5 to about 4 times. This creates a pressure of up to 6.5 bar fills the surrounding cavities and is therefore impermeable to water should do. When using such swelling agents, it must be taken into account that the swelling mass is not suddenly, but expands slowly over hours or days and consequently in changing areas with wet and dry periods only limited can be used. A striking advantage of source tapes, why they are used frequently is their ability to Joints between different materials such as Concrete, plastic, concrete / iron etc., to seal reliably.

Aus der DE 41 33 055 A1 ist eine eine Fuge überbrückende Dichtungsvorrichtung bekannt welche aus zwei, im Bereich der Stirnseiten von Betonplatten angeordneten L-förmigen Kunststoffprofilen, besteht. Die L-förmigen Kunststoffprofile werden mit einer L-Fläche an der Oberfläche der Betonplatten angeordnet, wobei sich der zweite L-Schenkel bzw. die zweite L-Fläche in die Fuge hinein erstreckt. Nachdem zwei derartig ausgestattete Betonplatten mit Stirnseiten sich gegenüberliegend aneinandergestellt werden, werden die freien, in die Fuge ragenden L-Schenkel miteinander verschweißt. Bei einer derartigen Vorrichtung ist von Nachteil, daß diese nur im Betonfertigteilbau verwendbar ist. Derartige Vorrichtungen beim Betonguß einer Wand in nebeneinanderliegende Betonierabschnitte einzugießen wäre zu aufwendig, da die Fuge zum späteren Verschweißen und um Verschmutzungen der aneinanderzuschweißenden Profile zu verhindern in aufwendiger Weise freigehalten werden müßte. Bei Bauvorhaben im Tiefbau ist es jedoch wünschenswert die Fugen so eng wie möglich auszugestalten und derartig breite Fugen, die die Stabilität des Bauwerks negativ beeinflussen zu vermeiden.DE 41 33 055 A1 describes a sealing device that bridges a joint known which from two, in the area of the end faces L-shaped plastic profiles arranged from concrete slabs, consists. The L-shaped plastic profiles are included an L surface arranged on the surface of the concrete slabs, wherein the second L-leg or the second L-surface in the Fug extends into it. After two concrete slabs equipped in this way with end faces facing each other the free L-legs protruding into the joint welded together. With such a device is disadvantageous that it can only be used in precast concrete construction is. Such devices when casting a wall in side by side Pouring in concrete sections would be too complex, because the joint for later welding and around dirt to prevent the profiles to be welded together in complex Way should be kept free. For construction projects in Civil engineering, however, it is desirable to keep the joints as tight as possible to design and such wide joints that the stability of the Avoid negative impact on the structure.

Aus der DE-G 93 20 134.6 ist eine injizierbare Fugenschiene bekannt, welche längs der Fuge zwischen zwei Betonierabschnitten eingestellt wird. Die Fugenschiene wird nach außen von Holzprofilen begrenzt, welche wiederum nach außen durch Polyethylenschläuche abgedichtet werden. Nachdem derartige Fugenlatten zwischen zwei geplante Betonierabschnitten eingestellt sind, wird zunächst ein Betonierabschnitt gegossen, wobei der Beton auch zwischen die Rippen der Fugenschiene fließt. Nach dem Erhärten des ersten Betonierabschnittes werden die Holzprofile und die Polyethylenschläuche entfernt und anschließend der zweite Betonierabschnitt gegossen. Nach dem Erhärten des zweiten Betonierabschnitts können die Schalungen abgenommen werden. Die Fugenschiene ist dann quer zur Längserstreckung der Wand im Stoßbereich der Betonierabschnitte quer im Beton eingebettet. DE-G 93 20 134.6 is an injectable joint rail known which along the joint between two concreting sections is set. The joint rail is exposed to the outside by wooden profiles limited, which in turn to the outside through polyethylene hoses be sealed. After such grout are set between two planned concreting sections, a pouring section is first poured, the concrete also flows between the ribs of the joint rail. After hardening of the first concreting section are the wood profiles and the polyethylene hoses removed and then the second Casting section poured. After the second concreting section has hardened the formwork can be removed. The Joint rail is then transverse to the longitudinal extension of the wall The joint area of the concreting sections is embedded across the concrete.

Hierdurch soll eine Schwächung der Betonstruktur in diesem Bereich erreicht werden, so daß sich in den Randbereichen der Fugenschiene Risse ausbilden. Sollte der Zusammenhalt zwischen Beton und der Fugenschiene welche aus Kunststoff besteht nicht ausreichend hoch sein und sich Risse bilden, können diese mit injizierter Dichtflüssigkeit abgedichtet werden. Hierbei ist von Nachteil, daß es mit einer derartigen Vorrichtung nicht möglich ist, die sich im Randbereich ausbildenden Risse zu injizieren und zu dichten, da der Weg, den die Injektionsflüssigkeit durch das Labyrinthsystem der Rippen der Fugenschiene zurücklegen muß, sehr lang ist. Auf diesem langen Weg findet ein erheblicher Abfall des Preßdrucks statt. Dies wird noch dadurch verstärkt, daß die Injektionsflüssigkeit zunächst senkrecht zum Riß eingepresst wird und erst dann den Riß entlang fließt. Durch die nicht injizierten Risse kann bei drückendem Wasser das Wasser in die Risse zumindest bis zur Fugenschiene hineingelangen. Durch dieses Wasser können die im Randbereich der Fugenschiene befindlichen Armierungen angegriffen werden und korrodieren. This is intended to weaken the concrete structure in this area be achieved so that in the peripheral areas of the Form cracks in the joint rail. Should the cohesion between Concrete and the joint rail which is not made of plastic are sufficiently high and cracks can form with them injected sealing liquid to be sealed. Here is from Disadvantage that it is not possible with such a device is to inject the cracks forming in the edge area and to seal because the way the injection fluid goes through the labyrinth system of the ribs of the joint rail must cover, is very long. On this long road there is a considerable one Drop in the baling pressure instead. This is reinforced by that the injection liquid is first pressed in perpendicular to the crack and only then flows along the crack. Through the Uninjected cracks can push the water in when the water is pressed the cracks at least reach the joint rail. By this water can be found in the edge area of the joint rail Reinforcements are attacked and corrode.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Abdichten von Betonfugen zu schaffen, die auf der Baustelle einfach bearbeitet, gehandhabt, an die Baumaßnahme angepaßt und einfach im Fugenbereich installiert werden kann und eine zuverlässige Abdichtung von Betonfugen gewährleistet.The invention has for its object a device for Sealing concrete joints to create that on the construction site simply processed, handled, adapted to the building project and can be easily installed in the joint area and a reliable one Sealing of concrete joints guaranteed.

Ferner soll ein Verfahren angegeben werden, mit welchem eine erfindungsgemäße Vorrichtung sicher und kostengünstig in eine Betonfuge eingebracht werden kann.Furthermore, a method is to be specified with which a Device according to the invention safely and inexpensively in a Concrete joint can be introduced.

Vorrichtungsmäßig wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.In terms of the device, the task is performed using a device solved the features of claim 1. Further advantageous configurations the invention are characterized in the subclaims.

Da die Dichtungsvorrichtung als streifenförmige Fugenlatte aus einem Hartkunststoff, insbesondere Hochdruckpolyethylen (HDPE), ausgebildet ist, die eine hohe Handhabungssteifheit aufweist, läßt sie sich in die Betonabschnitte genauso einfach wie die bekannten Blechstreifen einbringen und einbetten, wobei jedoch ihre Handhabung aufgrund des geringen Gewichtes wesentlich einfacher ist. Die Fugenlatte kann an komplizierte Formen, Winkel, Rundungen usw. vor Ort mittels z.B. eines Heißluftföns einfach durch Warmverformung angepaßt werden. Die Verarbeitung der Fugenlatte kann auf der Baustelle ausgeführt werden, wobei der Zuschnitt z.B. wie das Zuschneiden von Holz erfolgt und die Verbindung mit einem Schweißspiegel oer durch Heißkleben vorgenommen wird, so daß jeweils nur kleine Handgeräte benötigt werden.Since the sealing device as a strip-shaped joint lath a hard plastic, in particular high pressure polyethylene (HDPE), is designed that has a high handling rigidity, it can be inserted into the concrete sections just as easily as that Introduce and embed known sheet metal strips, however their handling is much easier due to the low weight is. The joint lath can adhere to complicated shapes, angles, Rounding etc. on site using e.g. of a hot air dryer be adapted by hot working. Processing the grout can be carried out on site, with the Cutting e.g. how the wood is cut and the Connection with a welding mirror or made by hot gluing is, so that only small handheld devices are required become.

Zudem ist die Verträglichkeit zwischen Beton bzw. Bindemittelmaterial und dem Hartkunststoff überraschend gut und bewirkt hohe Haftkräfte an den Grenzflächen. In einer vorteilhaften Ausführungsform ist die Oberfläche aufgerauht oder an der Oberfläche der Fugenplatte ist Quarzsand oder ähnliches feinkörniges Material eingearbeitet, wodurch die Verbindung zum Beton weiter verbessert wird.In addition, the compatibility between concrete or binder material and the hard plastic is surprisingly good and effective high adhesive forces at the interfaces. In an advantageous Embodiment, the surface is roughened or on the surface the joint plate is quartz sand or similar fine-grained Material incorporated, which continues the connection to the concrete is improved.

In einer weiteren vorteilhaften Ausführungsform ist die Fugenlatte mit an ihrer Oberfläche vorstehenden Verstärkungsstegen versehen, so daß auch bei einer geringen Materialstärke eine hohe Eigensteifigkeit erzielt wird.In a further advantageous embodiment, the joint lath with reinforcing bars protruding from their surface provided so that even with a low material thickness high inherent rigidity is achieved.

Anhand der Zeichnungen werden Ausführungsbeispiele der Erfindung näher erläutert. Es zeigen:

Die erfindungsgemäße Dichtungsvorrichtung ist zum Abdichten von Fugen 2 zwischen zwei Betonierabschnitten 3, 4 vorgesehen (Fig. 7 bis 11) und ist als streifen- bzw. stabförmige Fugenlatte (Fig. 1 bis 6) aus einem Hartkunststoff, insbesondere HDPE (Hochdruckpolyethylen) ausgebildet, wobei die Raumform bzw. die Abmessungen derart ausgelegt sind, daß die aus insbesondere warmverformbaren Hartkunststoff ausgebildete Fugenlatte eine Eigensteifigkeit aufweist, d.h. sich lattenartig verhält, elastisch biegbar und bruchsicher ist. Der Hartkunststoff ist vorzugsweise ein thermoplastischer Kunststoff, der in einem Temperaturbereich von -20°C bis +80°C formstabil und elastisch ist.The sealing device according to the invention is for sealing Joints 2 between two concreting sections 3, 4 are provided (Fig. 7 to 11) and is a strip or rod-shaped joint bar (Fig. 1 to 6) made of a hard plastic, especially HDPE (High pressure polyethylene), the spatial shape or the Dimensions are designed so that the particular thermoformed hard plastic trained joint bar Has inherent rigidity, i.e. behaves like a slat, elastic is bendable and unbreakable. The hard plastic is preferred a thermoplastic that is in a temperature range is dimensionally stable and elastic from -20 ° C to + 80 ° C.

Die steife Fugenlatte 1 ist relativ starr, so daß sie an einer Baustelle zu mehreren Stücken aufeinandergestapelt angeliefert werden kann. Die stabförmige Fugenlatte 1 wird vor Ort z. B. mit einem Heißluftfön oder einer anderen entsprechenden Wärmequelle warmverformt, z. B. verbogen, und an den Verlauf der Fugen 2 des zu erstellenden Mauerwerks angepaßt, wobei komplizierte Formen, wie Winkel, Rundungen usw. vor Ort leicht bewerkstelligt werden können.The rigid joint bar 1 is relatively rigid, so that it is attached to a Construction site delivered in several pieces stacked on top of each other can be. The rod-shaped joint bar 1 is z. B. with a hot air dryer or other appropriate heat source thermoformed, e.g. B. bent, and to the course of the joints 2 of the adapted to the masonry to be created, using complicated shapes, such as angles, curves, etc. are easily accomplished on site can.

Die einzelnen Fugenlatten 1 werden zu einer langen durchgehenden Fugenlatte zusammengesetzt, wobei sie an ihren Stoßkanten durch Schweißen bzw. Zusammenschmelzen oder durch eine Heißklebung oder Kaltklebung miteinander verbunden werden. Hierzu sind nur kleine Handgeräte, wie z. B. ein Schweißspiegel oder dergleichen notwendig, die unkompliziert in der Bedienung sind und auf einfache Art und Weise eine dichte Verbindung gewährleisten. Die Fugenlatten 1 können in gleicher Weise auch zu Kreuzungs- und Abzweigungselementen zusammengesetzt und auf die gleiche Weise miteinander verbunden werden, so daß beliebige Fugenverläufe mit ihnen abgedichtet werden können.The individual joint slats 1 become a long continuous Jointing slats assembled, passing through on their butt edges Welding or melting together or by hot gluing or cold glue can be connected. This is only small handheld devices such as B. a welding mirror or the like necessary, which are uncomplicated to use and simple Ensure a tight connection. The Joint slats 1 can also be used for crossing and Junction elements assembled and in the same way be connected to each other so that any course of joints can be sealed to them.

Die Fugenlatte 1 wird beim Herstellen des Mauerbereichs im Bereich um die Fuge 2 längs der Fuge und senkrecht zu den sich an den Betonierabschnitten 3, 4 bildenden Stoßflächen 5, 6 angeordnet, wobei sie vorzugsweise spiegelsymmetrisch zu den Stoßflächen 5, 6 angeordnet ist, so daß jeweils ein Schenkel 7, 8 der Fugenlatte 1 in einen Betonierabschnitt 3, 4 eingebettet ist.The joint bar 1 is used in the manufacture of the wall area in the area around the joint 2 along the joint and perpendicular to the the abutting surfaces 5, 6 forming the concreting sections 3, 4, preferably mirror-symmetrical to the abutting surfaces 5, 6 is arranged so that one leg 7, 8 each Joint bar 1 is embedded in a concreting section 3, 4.

Vor dem ersten Bentoniervorgang wird die Fugenlatte 1 wie die bekannten Blechstreifen an einer Bewehrung 9 beispielsweise mit Rödeldraht oder dergleichen befestigt, wobei aufgrund der hohen Eigensteifigkeit die Fugenlatte 1 selbsttragend ist und deshalb und aufgrund ihres geringen Gewichtes mit großen Abständen befestigt werden kann. Beim Vergießen mit Beton werden jeweils die Bewehrung 9 und ein Schenkel 7, 8 der Fugenlatte formschlüssig vom Beton des jeweiligen Betonierabschnitts 3, 4 umschlossen, so daß die Fugenlatte 1 beim Abbinden des Betons mit diesem eine dichte Verbindung eingeht und die Fuge für den Durchgang von Wasser sperrt. Hierbei hat sich überraschenderweise gezeigt, daß die Verträglichkeit von Beton mit aus Hartkunststoff, insbesondere HDPE, gefertigten Fugenlatten außerordentlich gut ist und aufgrund hoher Haftkräfte an den Grenzflächen eine feste Verbindung erzeugt. Die Haftung an den Grenzflächen zwischen der Fugenlatte 1 und dem Beton kann durch Aufrauhen der Oberfläche der Fugenlatte 1 oder Einarbeiten von Quarzsand oder ähnlichen feinen Körnern verbessert werden, so daß selbst bei ungünstigen Bedingungen eine feste und dichte Verbindung zwischen der Fugenlatte 1 und dem Beton erzielt wird.Before the first Bentoniervorgang the joint lath 1 is like that known sheet metal strips on a reinforcement 9 for example Fused wire or the like, being due to the high Rigidity the joint bar 1 is self-supporting and therefore and fastened with large distances due to their light weight can be. When pouring with concrete, the Reinforcement 9 and a leg 7, 8 of the joint lath enclosed by the concrete of the respective concreting section 3, 4, so that the joint bar 1 when setting the concrete with this one tight connection and the joint for the passage of Water locks. It has surprisingly been found that the compatibility of concrete with hard plastic, in particular HDPE, manufactured grout is extremely good and due to high adhesive forces at the interfaces, a firm connection generated. Liability at the interfaces between the Grout 1 and the concrete can be done by roughening the surface the joint lath 1 or incorporation of quartz sand or the like fine grains can be improved so that even with unfavorable Conditions a firm and tight connection between the joint lath 1 and the concrete is achieved.

In einer vorteilhaften Ausführung weist die Fugenlatte 1 einen z. B. im Querschnitt rechteckigen Basissteg 12 und beidseits seitlich z. B. senkrecht abstehende, sich in Längsrichtung erstreckende z. B. im Querschnitt ebenfalls rechteckige Versteifungsstege 13 auf, die daran einstückig angeformt sind. Die Versteifungsstege 13 erstrecken sich vorzugsweise durchgehend über die gesamte Länge des Basisstegs 12 und erhöhen so die Steifigkeit der Fugenlatte 1, so daß die Fugenlatte 1 mit einer geringeren Wandstärke bei gleicher Eigensteifigkeit ausgebildet werden kann.In an advantageous embodiment, the joint bar 1 has a e.g. B. in cross section rectangular base web 12 and on both sides sideways z. B. vertically protruding, extending in the longitudinal direction e.g. B. in cross section also rectangular stiffening webs 13, which are integrally formed thereon. The stiffening webs 13 extend preferably consistently over the entire length of the base web 12 and thus increase the rigidity of the joint bar 1, so that the joint bar 1 with a smaller wall thickness at the same Rigidity can be trained.

Die Versteifungsstege 13 sind schmale, flügelartige Elemente mit einer Wandstärke, die vorzugsweise der des Basisstegs 12 entspricht. Sie sind vorzugsweise symmetrisch um die Ebene des Basisstegs 12 und/oder symmetrisch um eine auf dem Basissteg 12 senkrecht stehende Quermittenebene 14 jeweils kreuzbalkenartig angeordnet. Die Versteifungsstege verlägern den Wasserweg nach Art einer Labyrinthdichtung und tragen so zur Erhöhung der Dichtigkeit bei.The stiffening webs 13 are narrow, wing-like elements with a wall thickness which preferably corresponds to that of the base web 12. They are preferably symmetrical about the plane of the Base web 12 and / or symmetrically around one on the base web 12 perpendicular transverse center plane 14 each like a cross bar arranged. The stiffening bars extend the waterway Kind of a labyrinth seal and thus contribute to increasing the tightness at.

Die Versteifungsstege 13 einer Fugenlatte 1 können alle mit gleicher Breite ausgebildet sein oder auch eine unterschiedliche Breite aufweisen. Zweckmäßigerweise haben die Versteifungsstege 13 eine Breite von 0,5 cm bis etwa 2 cm. An einer Seitenfläche eines Basisstegs 12 können für eine ideale Versteifung vier bis acht Versteifungsstege 13 vorgesehen werden, die in Abständen von etwa 2,5 bis 5 cm zueinander angeordnet sind. Die Breite bzw. Höhe der Basisstege 12 liegt zum Beispiel in einem Bereich zwischen 15 und 30 cm und beträgt vorzugsweise 20 bis 25 cm und die Dicke beträgt 3 bis 6 mm, vorzugsweise 4 bis 5 mm. Je breiter der Basissteg 12 ausgebildet ist, desto mehr Versteifungsstege 13 sollten daran vorgesehen sein. Die dünnwandigen Versteifungstege 13 sind im rechten Winkel an den Basissteg 12 angebunden.The stiffening webs 13 of a joint bar 1 can all with be of the same width or one have different widths. Conveniently the stiffening webs 13 have a width of 0.5 cm to about 2 cm. On a side surface of a base web 12 can for an ideal stiffening four to eight stiffening webs 13 is provided be that at intervals of about 2.5 to 5 cm to each other are arranged. The width or height of the base webs 12 for example lies in a range between 15 and 30 cm and is preferably 20 to 25 cm and the thickness is 3 to 6 mm, preferably 4 to 5 mm. The wider the base web 12 is formed is, the more stiffening webs 13 should be provided be. The thin-walled stiffening webs 13 are in the right Angle tied to the base web 12.

Erfindungsgemäß ist die Fugenlatte 1 (Fig. 1 bis 6) z. B. im Bereich ihrer Quermitte bzw. im Fugenbereich der Betonkörper mit einem an sich bekannten Injektionskanal 16 kombiniert, der eine nachträgliche Abdichtung der Arbeitsfuge 2 durch Eindrücken von Dichtmaterial in Fehlstellen im Fugenbereich ermöglicht Der Injektionskanal 16 wird zwischen den Betonierabschnitten 3, 4 im Bereich der Arbeitsfuge 2 angeordnet, wobei sowohl die Ausrichtung in Richtung zur Wasserseite, als auch entgegen zur Wasserseite möglich ist. Bezüglich der Injektionstechnik mit Dichtmaterial wird auf den Stand der Technik verwiesen, insbesondere auf die EP 0 418 699 A1.According to the joint bar 1 (Fig. 1 to 6) z. B. in Area of their transverse center or in the joint area of the concrete body an injection channel 16 known per se combined, the one subsequent sealing of construction joint 2 by pressing in Sealing material in imperfections in the joint area enables the Injection channel 16 is between the concreting sections 3, 4 in Area of the construction joint 2 arranged, both the alignment towards the water side, as well as against the water side is possible. Regarding the injection technique with sealing material is referred to the prior art, in particular to EP 0 418 699 A1.

Der einstückig angeformte Injektionskanal 16 wird von einer jeweils senkrecht zum Basissteg 12 angeordneten Decken- und Bodenwandung 18, 19 und zwei Seitenwandungen 20, 21 begrenzt. Die Seitenwandungen 20, 21 sind seitlich um den Basissteg 12 versetzt angeordnet, wobei sie etwa um die Stärke des Basisstegs 12 voneinander beabstandet sind. Die Wandungen 18 bis 21 bilden somit einen im Querschnitt rechteckigen Kanal.The injection channel 16, which is formed in one piece, is provided by a each arranged perpendicular to the base web 12 ceiling and Bottom wall 18, 19 and two side walls 20, 21 limited. The side walls 20, 21 are laterally around the base web 12 staggered, about the thickness of the base web 12 are spaced apart. Form the walls 18 to 21 thus a channel with a rectangular cross section.

In einer der beiden Seitenwandungen 20, 21 ist eine Öffnung 22 eingebracht, durch die das injizierte Dichtmaterial austreten kann. Die Öffnung 21 ist ein sich über die gesamte Länge der Fugenlatte 1 erstreckender Schlitz. Sie kann aber auch in Form von mehreren vertikal versetzten Löchern, insbesondere in Längsrichtung angeordneten Langlöchern, ausgebildet sein, so daß die mit der Öffnung 22 versehene Seitenwand 20, 21 steif ist und eine Trag- bzw. Versteifungsfunktion an der Fugenlatte 1 übernimmt.There is an opening 22 in one of the two side walls 20, 21 introduced through which the injected sealing material emerge can. The opening 21 is a along the entire length of the Joint slat 1 extending slot. But it can also be in shape of several vertically offset holes, especially in the longitudinal direction arranged elongated holes, be formed so that the with the opening 22 side wall 20, 21 is rigid and a supporting or stiffening function on the joint bar 1 takes over.

Vorzugsweise sind die Boden- und Deckenwandung 18, 19 an der Seite der Öffnung 22 oder beidseitig in Form von Versteifungsstegen 13a verlängert, so daß sie mit der daran angrenzenden Seitenwandung 21, die die Öffnung 22 aufweist, eine U-förmige Ausnehmung bzw. Rinne zur Aufnahme eines offenzelligen Schaumstoffstreifens 23 begrenzen. Der Schaumstoffstreifen 23 füllt sich beim Injizieren von Dichtmaterial mit Dichtmaterial und bildet somit einen weiteren, zum Injektionskanal 16 parallel verlaufenden Kanalabschnitt zur Aufnahme und zum Verteilen des Dichtmaterials. Die Zellengröße des offenzelligen Schaumstoffstreifens 24 ist so gewählt, daß beim Betonieren kein Beton durch die Öffnung 22 in den Injektionskanal 16 eindringt. Für das unter Druck in den Injektionskanal 16 injizierte Dichtmaterial ist der Schaumstoffstreifen 23 jedoch durchlässig, so daß sich das Dichtmaterial nach außen in einen unerwünschten Hohlraum ausbreiten und diesen abdichtend ausfüllen kann.Preferably, the bottom and top walls 18, 19 are on the Side of the opening 22 or on both sides in the form of stiffening webs 13a extended so that it with the adjacent Side wall 21, which has the opening 22, a U-shaped Recess or groove for receiving an open-cell foam strip 23 limit. The foam strip 23 fills when injecting sealing material with sealing material and thus forms another, parallel to the injection channel 16 running channel section for receiving and distributing the Sealing material. The cell size of the open cell foam strip 24 is chosen so that no concrete when concreting penetrates into the injection channel 16 through the opening 22. For the sealing material injected under pressure into the injection channel 16 However, the foam strip 23 is permeable, so that the sealing material to the outside in an undesirable cavity spread and fill it sealingly.

In einer speziellen Ausführungsform ist die Öffnung 22 des Injektionskanals 16 von einem geschlossenzelligen Schaumstoffstreifen 24 z.B. aus elastischem Material abgedeckt, der für das Dichtmaterial undurchlässig ist. Der geschlossenzellige Schaumstoffstreifen 24 hat im Querschnitt eine etwa trapezförmige Form mit einer innen die Öffnung 22 abdeckenden Schmalseitenfläche 25, einer außen liegenden Breitseitenfläche 26 und zwei sich zwischen der Schmalseitenfläche 25 und der Breitseitenfläche 26 erstreckende Schrägflächen 27, 28. Die durch die Seitenwandungen 20, 21 und die Versteifungsstege 13a begrenzte Rinne ist in ihrer Querschnittsform an die Form des geschlossenzelligen Schaumstoffstreifens angepaßt, indem in dem Winkelbereich zwischen der Seitenwandung 21 und den Versteifungsstegen 13a im Querschnitt dreiecksförmige Wandungen 29 angeformt sind, die jeweils eine zu den Schrägflächen 27, 28 korrespondierende Schrägfläche bilden.In a special embodiment, the opening 22 is the injection channel 16 from a closed cell foam strip 24 e.g. made of elastic material, which for the Sealing material is impermeable. The closed cell foam strip 24 has an approximately trapezoidal shape in cross section with a narrow side surface covering the inside of the opening 22 25, an outer broad side surface 26 and two themselves between the narrow side surface 25 and the broad side surface 26 extending inclined surfaces 27, 28. The through the side walls 20, 21 and the stiffening webs 13a limited groove is in their cross-sectional shape to the shape of the closed cell Foam strip adjusted by in the angular range between the side wall 21 and the stiffening webs 13a in Cross-section triangular walls 29 are formed, the one each corresponding to the inclined surfaces 27, 28 Form sloping surface.

Wird in diesen Injektionskanal 16 nach dem Vergießen und Abbinden des Betons Dichtmaterial in an sich bekannter Weise mit an sich bekannten Mitteln unter Druck injiziert, hebt es ventilartig den Schaumstoffstreifen 24 von den Schrägflächen der Rinne ab und kann nach außen in angrenzende Hohlräume treten. Dabei wird der Schaumstoffstreifen zusammengedrückt. Bei nachlassendem Druck geht der Schaumstoffstreifen 24 zurück in seine Ausgangsraumform, so daß er wieder flächig an den Schrägflächen der Rinne der Fugenlatte 1 anliegt und in der Art eines Ventils die Öffnung 22 des Injektionskanals wieder schließt.Is in this injection channel 16 after casting and setting of the concrete sealing material in a manner known per se injected under pressure, it lifts valve-like the foam strip 24 from the inclined surfaces of the channel and can step out into adjacent cavities. Here the foam strip is pressed together. When it wears off Pressure, the foam strip 24 returns to its original shape, so that it is again flat on the inclined surfaces of the Groove of joint bar 1 abuts and in the manner of a valve Opening 22 of the injection channel closes again.

Zusätzlich zu einem Injektionskanal 16 kann die Fugenlatte 1 an ihrer Quermitte bzw. im Fugenbereich auch zusätzlich mit einem Quellband 31 versehen sein (Fig. 4). Das Quellband 31 Ist formschlüssig im eine durch den Basissteg 12 und zwei in der Nähe der Quermitte angeordneten Versteifungsstegen 13b gebildeten U-förmigen Ausnehmung bzw. Rinne bzw. Nut aufgenommen, wobei an der einen Seite des Basisstegs 12 ein Quellband 31 und auf der anderen Seite ein Imjektionskanal 16 angeordnet ist. Sowohl das Quellband 31, als auch der Injektionskanal 16 sind am der Quermitte der Fugenlatte 1 angeordnet, die im eingebauten Zustand des Fugenbandes sich im Fugenbereich der Betonkörper 3, 4 befindet.In addition to an injection channel 16, the joint lath 1 can be attached their cross center or in the joint area also with a Be swelling tape 31 (Fig. 4). The swelling band 31 is form-fitting in one through base bridge 12 and two nearby of the transverse center arranged stiffening webs 13b U-shaped recess or groove or groove added, with one side of the base web 12 a swelling tape 31 and on the an injection channel 16 is arranged on the other side. Both that The swelling band 31 and the injection channel 16 are at the center of the cross the grout 1 arranged in the installed state the joint tape is in the joint area of the concrete body 3, 4.

In einer besonders wirksamen und dennoch einfachen Ausführungsform (Fig. 5) ist die Fugenlatte 1 zusätzlich oder alternativ im Bereich ihrer außen liegenden Längsseitenwänder bzw. -kanten 32, 33 jeweils mit einem Quellmittel, wie z. B. einer Quellfolie 34 oder einem Quellband 31 versehen. Die Längsseitenränder 32, 33 sind die Bereiche der Fugenlatte 1, die am tiefsten in die Betonierabschnitte 3, 4 eintauchen, so daß die Wahrscheinlichkeit der Ausbildung von Fehlstellen oder dergleichen äußerst gering ist, indem sich das Quellmittel in diesem Bereich vollkommen zwischen den die Fugenlatte 1 umgebenden Beton und der Fugenlatte 1 einschmiegt und auch unter schwierigen Bedingungen eine dichte Fuge gewährleistet.In a particularly effective, yet simple embodiment (Fig. 5) is the joint lath 1 additionally or alternatively in Area of their outer longitudinal side walls or edges 32, 33 each with a swelling agent, such as. B. a swelling film 34 or provided a swelling tape 31. The longitudinal side edges 32, 33 are the areas of the joint bar 1, which plunge deeply into the concreting sections 3, 4 so that the Probability of the formation of defects or the like is extremely low by the swelling agent in this Area completely between those surrounding the joint batten 1 Concrete and the grout 1 nestles and even under difficult Conditions ensure a tight joint.

Die Fugenlatten 1 mit Quellfolie 34 sind vorzugsweise ohne Versteifungsstege 13 ausgebildet, da an den ebenen Schenkeln 7, 8 der Fugenlatte 1 die Quellfolie einfacher aufgeklebt werden kann. Die Quellfolien 34 erstrecken sich von den außen liegenden Längsseitenkanten 32, 33 über etwa 2/3 bis 4/5 der Schenkelbreite der Fugenlatte 1.The joint slats 1 with swelling film 34 are preferably without stiffening webs 13 formed because on the flat legs 7, 8th the joint lath 1, the swelling film can be glued more easily can. The source foils 34 extend from the outside Longitudinal edges 32, 33 over approximately 2/3 to 4/5 of the leg width the grout 1.

Sind die Fugenlatten 1 im Bereich ihrer Längsseitenränder 32, 33 mit Quellbändern 31 versehen (Fig. 6), so werden vorzugsweise Fugenplatten mit Versteifungsstegen 13 verwendet, wobei die Quellbänder 31 jeweils in eine Eckausnehmung 35, die aus dem äußersten Versteifungssteg 13c und dem Endbereich des Basisstegs 12 gebildet wird, eingeklebt wird. Vorzugsweise weist eine solche Fugenlatte 1 vier Quellbänder 31 auf, wobei an jedem Längsseitenrand 32, 33 auf beiden Seiten des Basisstegs 12 ein Quellband 31 angeordnet ist.Are the joint slats 1 in the area of their longitudinal side edges 32, 33 provided with swelling bands 31 (Fig. 6), so preferably Joint plates with stiffening webs 13 used, the Swelling bands 31 each in a corner recess 35, which from the outermost stiffening web 13c and the end region of the base web 12 is formed, is glued. Preferably one has Joint lath 1 on four swelling tapes 31, with on each long edge 32, 33 a swelling band on both sides of the base web 12 31 is arranged.

Die Bewehrung 9 in den Betonierabschnitten 3, 4 muß so angeordnet sein, daß sie die Fugenlatte 1 nicht kreuzt (Fig. 7 bis 11). Dies kann beispielsweise bei einer Fuge zwischen einer Sohlplatte 36 und einem Wandabschnitt 37 dadurch erreicht werden, daß die Bewehrung 9 der Sohlplatte 36 im Bereich unterhalb der Fuge 2 nach unten versetzt angeordnet ist. Die Bewehrung 9 hat dann beispielsweise im Querschnitt eine Form eines flachliegenden U's, das seitlich offen ist, mit einem unteren Bereich 9a, einem seitlichen Verbindungsbereich 9b und einem oberen Bereich 9c. Der obere Bereich 9c ist außerhalb des Fugenbereichs, wie es üblich ist, kurz unterhalb der Oberfläche der Sohlplatte 36 angeordnet, wobei er zu dem Bereich unterhalb der Fuge 2 hin durch eine Stufe 39 nach unten versetzt ist und so mit Abstand zur Oberfläche verläuft (Fig. 7). Im Wandabschnitt 37 sind vertikale Bewehrungsstreben 40 eingebracht, die parallel zu der Fugenlatte 1 verlaufen und sich somit nicht mit dieser kreuzen.The reinforcement 9 in the concreting sections 3, 4 must be arranged in this way be that it does not cross the joint bar 1 (Fig. 7 to 11). This can be the case, for example, with a joint between a base plate 36 and a wall section 37 can be achieved in that the reinforcement 9 of the base plate 36 in the area below the joint 2 is arranged offset downwards. The reinforcement 9 then has a shape of a flat lying, for example in cross section U's, which is open on the side, with a lower area 9a, a side connection area 9b and an upper Area 9c. The upper area 9c is outside the joint area, as is common, just below the surface of the Sole plate 36 arranged to the area below the Fuge 2 down by a step 39 and so runs at a distance from the surface (Fig. 7). In the wall section 37 vertical reinforcement struts 40 are introduced, which are parallel run to the joint lath 1 and therefore not with this cross.

Der Abstand zwischen der Fuge 2 und der Bewehrung 9 der Sohlplatte 36 kann auch durch einen stufenförmigen Wandansatz 41 an der Sohlplatte 36 erreicht werden (Fig. 8), wobei der Wandansatz 41 im Bereich unterhalb des Wandabschnitts 37 aus Beton einstückig mit der Sohlplatte 36 ausgebildet ist und sich von der Sohlplatte 36 nach oben mit einer Breite und Länge erstreckt, die dem Wandabschnitt entspricht. In diesem Wandansatz 41 ist der untere Schenkel 8 der Fugenlatte 1 eingegossen und hat ausreichend Raum, so daß sie sich nicht mit der darunter quer verlaufenden Bewehrung 9 der Sohlplatte 36 kreuzt. Der obere Schenkel 7 der Fugenlatte 1 ist in den auf der Sohlplatte 36 stehenden Wandabschnitt 37 eingebettet.The distance between the joint 2 and the reinforcement 9 of the base plate 36 can also by a step-shaped wall extension 41 the sole plate 36 can be reached (Fig. 8), the wall approach 41 in the area below the wall section 37 made of concrete is integrally formed with the sole plate 36 and from the sole plate 36 extends upward with a width and length, which corresponds to the wall section. In this approach to the wall 41, the lower leg 8 of the joint bar 1 is cast in and has enough space so that it doesn't interfere with the one below cross reinforcement 9 of the base plate 36 crosses. Of the The upper leg 7 of the joint bar 1 is in the on the sole plate 36 standing wall section 37 embedded.

Bei der Verbindung zweier Etappen 42, 43 (Fig. 11) einer Sohlplatte bzw. eines Wandabschnitts wird die Fugenlatte quer zur Fuge 2 und somit parallel zu den der Bodenplatte bzw. im Wandabschnitt eingebrachten Bewehrungselementen angeordnet, so daß es keine Überkreuzungen zwischen der Bewehrung und der Fugenlatte gibt.When connecting two stages 42, 43 (FIG. 11) of a sole plate or a wall section, the joint bar is transverse to Joint 2 and thus parallel to that of the floor slab or in the wall section inserted reinforcement elements arranged so that there is no crossover between the reinforcement and the joint bar gives.

Zur Verbesserung der Haltkraft zwischen der Fugenlatte 1 und den sie umgebenden Beton bzw. das sie umgebende Bindemittel ist die Fugenlatte 1 an ihrer Oberfläche aufgerauht. Vorzugsweise ist Quarzsand oder ähnliches feinkörniges Material in die Oberfläche der Fugenlatte 1 eingearbeitet, wodurch eine ideale Verbindung zwischen der Fugenlatte 1 und den sie umgebenden Beton erreicht wird.To improve the holding force between the joint bar 1 and the surrounding concrete or binder is the Joint bar 1 roughened on its surface. Preferably Quartz sand or similar fine-grained material in the surface the joint bar 1 incorporated, creating an ideal connection reached between the joint bar 1 and the surrounding concrete becomes.

Rechtwinklige standardisierte Formteile der erfindungsgemäßen Fugenlatte 1 für Kreuzungs- bzw. Abzweigungsstellen mit drei bzw. vier Schenkeln lassen sich auf der Baustelle an die jeweils zu erstellende Baumaßnahme einfach anpassen, indem zwei bzw. drei Schenkel räumlich fixiert werden und das Formteil im Verbindungsbereich erwärmt wird, so daß der eine freie Schenkel in einen gewünschten Winkel gebogen werden kann. Die gebogenen Formteile werden dann in der oben beschriebenen Art und Weise mit stabförmigen Fugenlatten 1 verbunden.Right-angled standardized molded parts of the inventive Joint bar 1 for intersections or branches with three or four legs can be attached to the respective on site Simply adapt the construction project to be created by two or three legs are spatially fixed and the molded part in the connection area is heated so that a free leg in a desired angle can be bent. The curved Moldings are then made in the manner described above connected with rod-shaped joint slats 1.
