Abstract

The joint tape holder has two identical elements (1), each with several strip-shaped profiles with one U-shaped (4) and two straight sections. The profiles are arranged at a distance apart and parallel to each other on at least one rod that passes into an attachment plate (14) at one end for attaching the holding element to a lining sole. An independent claim is also included for a method of simultaneously manufacturing two concreting sections separated by a joint using an inventive holder.

Description

Die Erfindung betrifft eine Halterung für ein Fugenband sowie ein Verfahren zur Herstellung von zwei durch eine Fuge getrennten Betonierungsabschnitten, die wasserundurchlässig durch ein Fugenband miteinander verbunden sind.The invention relates to a holder for a joint tape and a method for producing two separate by a joint concreting sections, which are connected to each other impermeable to water by a joint tape.

Fugenbänder dienen zum elastischen Abdichten von BetonBauwerken im Bereich von zwischen jeweils zwei benachbarten Beton-Bauteilen gebildeten Dehnungs-, Bewegungs- bzw. Arbeitsfugen. Zur Abdichtung wird jeweils eine Seitenbahn des Fugenbandes in eines der Beton-Bauteile eingebettet. Die Seitenbahn besitzt regelmäßig eine Profilierung, um einen möglichst langen Wasserumlaufweg zu bilden. Um den maximal möglichen Wasserumlaufweg zu gewährleisten, ist es notwendig, das Fugenband vor dem Betonieren derart an der Verschalung zu befestigen, dass sich die Seitenbahnen möglichst senkrecht zu der Fuge in den Beton hinein erstrecken. Es muss folglich durch eine geeignete Befestigung verhindert werden, dass die Seitenbahnen durch ihr Eigengewicht oder durch herabstürzenden Beton verbogen werden oder in unkontrollierter Lage in den Beton eingebettet werden.Joint tapes serve for the elastic sealing of concrete structures in the area of expansion, movement or working joints formed between two respective adjacent concrete components. For sealing, a side track of the joint tape is embedded in one of the concrete components. The side track regularly has a profiling to form the longest possible water circulation path. To ensure the maximum possible water circulation path, it is necessary to fasten the joint tape to the casing before concreting in such a way that the side panels extend into the concrete as perpendicularly as possible to the joint. It must therefore be prevented by a suitable attachment that the side panels are bent by their own weight or by falling concrete or embedded in an uncontrolled position in the concrete.

Zu diesem Zweck ist es beispielsweise bekannt, an den Randwulsten der Seitenbahn Klammern zu befestigen, die in Abständen von etwa 30 cm bis 50 cm voneinander angeordnet werden. An diesen Klammern werden Bindedrähte, sogenannte Rödeldrähte, befestigt, mit denen dann die Seitenbahn in ihrer vorbestimmten Lage durch schräges Abspannen fixiert wird. Bekannte Fugenbänder bestehen vorzugsweise aus thermoplastischen elastischen Kunststoffen, durch die eine weitgehende Abdichtung gegen Feuchtigkeit und andere Flüssigkeiten, die sonst zwischen den Betonbauwerken hindurchtreten könnten, erzielt wird.For this purpose, it is known, for example, to attach to the edge beads of the side panel brackets, which are arranged at intervals of about 30 cm to 50 cm from each other. At these brackets binding wires, so-called Rödeldrähte, attached, with which then the side panel is fixed in its predetermined position by oblique clamping. Known waterstops are preferably made of thermoplastic, thermoplastic materials, which provide a substantial seal against moisture and other liquids that might otherwise pass between the concrete structures.

Fugenbänder kommen beispielsweise zur Anwendung, wenn Kellerwände benachbarter Gebäude in wasserundurchlässiger Weise miteinander verbunden werden sollen, so wie dies insbesondere bei der Erstellung von Reihen- und Doppelhäusern erforderlich ist. Bisher werden in solchen Fällen die Kellerwände der benachbarten Häuser zeitlich gestaffelt betoniert. Zunächst muss eine Fugenschalung unter Einbindung des Fugenbandes des ersten Betonierungsabschnittes hergestellt werden, bevor nach deren Aushärtung der zweite Betonierungsabschnitt unter Einbindung der noch freien Seitenbahn des Fugenbandes hergestellt werden kann.Joint tapes are used, for example, when basement walls of adjacent buildings are to be connected to each other in a water-impermeable manner, as is required in particular in the construction of terraced and semi-detached houses. So far, the basement walls of neighboring houses are staggered in stages in such cases. First, a joint formwork must be made with the involvement of the joint tape of the first concreting section, before the second concreting section can be produced with the integration of the still free side track of the joint strip after its hardening.

Eine Halterung für ein Fugenband ist ebenfalls im Dokument DE 29 720 926 U dargestellt.A holder for a joint tape is also in the document DE 29 720 926 U shown.

Eine wasserundurchlässige Verbindung zeitlich gestaffelter Betonierungsabschnitte mittels Fugenbändern ist daher recht zeitaufwändig und arbeitsintensiv. Darüber hinaus bedingen die zeitlich gestaffelten Betonierungsabschnitte eine mehrmalige Anlieferung kleinerer Betonmengen, was eine Erhöhung der Anlieferkosten zur Folge hat.A waterproof connection temporally staggered concreting sections using joint tapes is therefore quite time consuming and labor intensive. In addition, the temporally staggered concreting sections require a repeated delivery of smaller quantities of concrete, which results in an increase in delivery costs.

Ausgehend von diesem Stand der Technik besteht daher ein Bedürfnis, eine Halterung für Fugenbänder zu schaffen, die zumindest eine teilweise gleichzeitige oder unmittelbar aufeinanderfolgende Herstellung von zwei durch eine Fuge getrennten Betonierungsabschnitten ermöglicht, wobei die Halterung konstruktiv einfach und preiswert herstellbar sowie einfach handhabbar sein soll. Des Weiteren liegt der Erfindung die Aufgabe zugrunde ein vorteilhaftes Verfahren zur Herstellung von zwei durch eine Fuge getrennten Betonierungsabschnitten vorzuschlagen.Based on this prior art, therefore, there is a need to provide a support for joint tapes, which allows at least a partially simultaneous or immediately successive production of two separated by a joint concreting sections, the bracket should be structurally simple and inexpensive to manufacture and easy to handle. Furthermore, the object of the invention is to propose an advantageous method for the production of two concreting sections separated by a joint.

Diese Aufgabe wird erfindungsgemäß durch eine Halterung für ein Fugenband gelöst, die zwei baugleiche Halterungselemente umfasst, wobei jedes Halterungselement mehrere bandförmige Profile mit einem U-förmigen und zwei von den Schenkelenden des U-förmigen Abschnitts ausgehenden geraden Abschnitten aufweist und die bandförmigen Profile an ihrer in Richtung des U-förmigen Abschnitts weisenden Seite im Abstand und parallel zueinander an mindestens einem Stab angeordnet sind, der endseitig in eine Befestigungsplatte zur Befestigung des Halterungselements auf einer Schalungssohle übergeht.This object is achieved by a holder for a joint tape comprising two identical support members, each support member having a plurality of band-shaped profiles with a U-shaped and two outgoing from the leg ends of the U-shaped section straight sections and the band-shaped profiles at their in direction the U-shaped portion facing side are arranged at a distance and parallel to each other at least one rod, which merges at the end into a mounting plate for fixing the support member on a formwork sole.

Die U-förmigen Abschnitte der bandförmigen Profile der sich gegenüberstehenden Halterungselemente der Anordnung dienen als Aufnahme für die Seitenbahnen des Fugenbandes, das bei einer Fuge zwischen aneinander grenzenden Kellerwänden von der Schalungssohle senkrecht nach oben und quer zur Fuge verläuft.The U-shaped portions of the band-shaped profiles of the opposing support members of the assembly serve as a receptacle for the side panels of the joint tape, which extends at a joint between adjacent basement walls of the formwork sole perpendicular to the top and transverse to the joint.

An den geraden Abschnitten der bandförmigen Profile der sich gegenüberstehenden Halterungselemente liegen die die Fuge ausfüllenden Dämmstoffe, insbesondere Dämmplatten, an, die zudem während des Betonierens die Funktion der Fugenschalhaut übernehmen. Bei herkömmlichen, zeitlich gestaffelten Betonierungsabschnitten muss diese Fugenschalhaut nacheinander für die die Fuge begrenzenden Flächen hergestellt werden.At the straight sections of the band-shaped profiles of the opposing support members are the fugue-filling insulation materials, in particular insulation boards on, which also take over the function of the joint shell during concreting. For conventional staggered concreting sections, these joint shells must be produced in succession for the surfaces delimiting the joint.

Mit Hilfe der erfindungsgemäßen Anordnung ist ein zeitgleiches oder unmittelbar aufeinander folgendes Betonieren von zwei benachbarten, eine Fuge ausbildenden Betonierungsabschnitten möglich. Die hierzu erforderlichen Halterungselemente werden aus preiswertem Baustahl hergestellt.With the aid of the arrangement according to the invention, simultaneous or immediately successive concreting of two adjacent concreting sections forming a joint is possible. The support elements required for this purpose are made of inexpensive structural steel.

Eine besonders verbindungssteife und stabile Ausführung der Halterungselemente zeichnet sich dadurch aus, dass die bandförmigen Profile jedes Halterungselementes an mindestens zwei als Winkelprofile ausgestalteten Stäben angeordnet sind. Die Winkelprofile weisen eine hohe Knicksteifigkeit aus und verhindern damit wirksam eine Verbiegung der Halterungselemente unter der Einwirkung des Betons. Hierdurch wird gewährleistet, dass das Fugenband während des Eingießens des Betons in der vorbestimmten Position senkrecht zum Fugenverlauf fixiert wird.A particularly rigid connection and stable embodiment of the support members is characterized in that the band-shaped profiles of each support member are arranged on at least two rods designed as angle profiles. The angle profiles have a high buckling resistance and thus effectively prevent bending of the support elements under the action of the concrete. This ensures that the joint tape during the pouring of the concrete is fixed in the predetermined position perpendicular to the joint profile.

Darüber hinaus lassen sich an den unteren Enden der Winkelprofile Befestigungsbleche anschweißen, die eine problemlose Aufstellung und Befestigung der Halterungselemente auf der Betoniersohle ermöglichen. Vorzugsweise befinden sich die Winkelprofile zu beiden Seiten der U-förmigen Abschnitte. Sofern die geraden Abschnitte der bandförmigen Profile unterschiedlich lang sind, kann darüber hinaus ein weiteres Winkelprofil im Randbereich des längeren geraden Abschnitts angeordnet sein.In addition, can be welded to the lower ends of the angle profiles mounting plates that allow easy installation and attachment of the support elements on the concrete sole. Preferably, the angle profiles are located on both sides of the U-shaped sections. If the straight sections of the band-shaped profiles are of different lengths, a further angle profile can additionally be arranged in the edge region of the longer straight section.

Entsprechend dem üblichen Verlauf einer senkrechten Fuge zwischen zwei Betonierungsabschnitten, insbesondere den Kellerwänden von benachbarten Gebäuden, gehen die geraden Abschnitte der Halterungselemente vorzugsweise rechtwinkelig von den Schenkelwänden des U-förmigen Abschnitts aus.According to the usual course of a vertical joint between two concreting sections, in particular the basement walls of adjacent buildings, the straight sections of the support elements preferably extend at right angles from the leg walls of the U-shaped section.

Um eine möglichst kontrollierte Einbettung des Fugenbandes senkrecht zu der Fuge in dem Beton zu bewirken, ist es erfindungsgemäß vorgesehen, dass die beiden Halterungselemente im Abstand zueinander derart auf der Schalungssohle befestigt sind, dass die geraden Abschnitte der bandförmigen Profile der sich gegenüberstehenden Halterungselemente parallel zueinander ausgerichtet sind und die U-förmigen Abschnitte der bandförmigen Profile der sich gegenüberstehenden Halterungselemente eine Aufnahme für das Fugenband bilden. Durch die streng parallele Ausrichtung der sich gegenüberstehenden identischen Halterungselemente wird der gewünschte Fugenverlauf sowie die senkrecht dazu verlaufende Einbettung des Fugenbandes sichergestellt. Der Abstand der geraden Abschnitte der bandförmigen Profile der sich gegenüberstehenden Halterungselemente wird bei deren Befestigung auf der Schalungssohle so gewählt, dass er einer geforderten Fugenbreite entspricht. Der durch die geraden Abschnitte der bandförmigen Profile gebildete Zwischenraum wird mit Dämmstoffen, insbesondere Dämmplatten aufgefüllt, die während des Betonierens zugleich als Fugenschalhaut dienen, indem sie die Fuge frei von Beton halten.In order to effect the most controlled possible embedment of the joint strip perpendicular to the joint in the concrete, it is provided according to the invention that the two support members are fixed to each other at a distance to each other on the formwork sole that the straight portions of the band-shaped profiles of the opposing support members aligned parallel to each other are and the U-shaped portions of the band-shaped profiles of the opposing support members form a receptacle for the joint tape. Due to the strictly parallel alignment of the opposing identical support elements of the desired joint profile and the perpendicular thereto embedding of the joint strip is ensured. The distance of the straight portions of the band-shaped profiles of the opposing support members is chosen so that it corresponds to a required joint width in their attachment to the formwork sole. The one by the straight Intermediate space formed sections of the band-shaped profiles is filled with insulating materials, especially insulation boards, which also serve as a joint shell during concreting by keeping the joint free of concrete.

In einer weiteren bevorzugten Ausgestaltung der Erfindung ist es vorgesehen, dass die geraden Abschnitte der bandförmigen Profile jedes Halterungselement endseitig rechtwinkelig abgewinkelt sind und auf den nach außen weisenden Seiten jedes abgewinkelten Abschnitts ein Abstandshalter angeordnet ist. Die Abstandshalter liegen nach der Montage der Halterungselemente an der Schalhaut der Betonierungsabschnitte an. Aufgrund der Abstandshalter wird verhindert, dass die metallischen bandförmigen Profile der Halterungselemente bis an die Außenhaut des Betonierungsabschnitts heranreichen.In a further preferred embodiment of the invention, it is provided that the straight portions of the band-shaped profiles of each support member are angled at right angles to the end and on the outwardly facing sides of each angled portion, a spacer is arranged. The spacers are after the mounting of the support elements on the formwork of the concreting sections. Due to the spacers prevents the metallic band-shaped profiles of the support members reach up to the outer skin of the concreting section.

  • einseitig eine erste Schalhaut für beide Betonierungsabschnitte auf einer Schalungssohle errichtet wird,

Die erfindungsgemäße Halterung für ein Fugenband besteht aus zwei baugleichen mit 1 bezeichneten Halterungselementen. Jedes Halterungselement 1 besteht aus insgesamt sieben bandförmigen Flachstahl-Profilen 2, die in einem Abstand von etwa 35 cm mit drei senkrecht zu den Flachstahl-Profilen 2 verlaufenden winkelprofilen 3 verschweißt sind. Jedes Flachstahl-Profil 2 weist einen U-förmigen Abschnitt 4 und zwei von den Schenkelenden des U-förmigen Abschnitts 4 ausgehende gerade Abschnitte 5, 6 auf. Die Flachstahl-Profile 2 sind in exakt paralleler Ausrichtung zueinander an den Winkelprofilen 3 angeschweißt, so dass sämtliche U-förmigen Abschnitte 4 miteinander fluchten und damit eine Aufnahmekammer für eine der Seitenbahnen 7a, 7b eines Fugenbandes 8 bilden.The holder according to the invention for a joint tape consists of two identical with 1 designated support elements. Each support member 1 consists of a total of seven band-shaped flat steel profiles 2, which are welded at a distance of about 35 cm with three perpendicular to the flat steel profiles 2 angle sections 3. Each flat steel profile 2 has a U-shaped section 4 and two straight sections 5, 6 extending from the leg ends of the U-shaped section 4. The flat steel profiles 2 are welded in exactly parallel alignment with one another on the angle profiles 3, so that all U-shaped sections 4 are aligned with each other and thus form a receiving chamber for one of the side panels 7a, 7b of a joint strip 8.

Die geraden Abschnitte 5, 6 der Flachstahl-Profile 2 sind endseitig rechtwinkelig abgewinkelt. Auf der nach außen weisenden Seite der abgewinkelten Abschnitte 9, 11 sind Abstandshalter 12, 13 angeordnet, die im Ausführungsbeispiel aus Gummi bestehen.The straight sections 5, 6 of the flat steel profiles 2 are angled right angles at the ends. On the outwardly facing side of the angled portions 9, 11 spacers 12, 13 are arranged, which consist of rubber in the embodiment.

Wie deutlich aus Figuren 1a, b erkennbar, sind die Winkelprofile 3 auf derjenigen Seite der geraden Abschnitte 5,6 angeschweißt, die in Richtung des U-förmigen Abschnitts 4 weisen. Hierdurch wird gewährleistet, dass die geraden Abschnitte 5,6 auf der dem U-förmigen Abschnitt gegenüberliegenden Seite zusammen eine gerade Auflagefläche für das Dämmmaterial, insbesondere in Form von Dämmplatten, bilden, die zwischen zwei sich gegenüberstehenden Halterungselementen 1 eingebracht werden.As can be seen clearly from FIGS. 1 a, b, the angle profiles 3 are welded on the side of the straight sections 5, 6 pointing in the direction of the U-shaped section 4. This ensures that the straight sections 5, 6 on the side opposite the U-shaped section together form a straight bearing surface for the insulating material, in particular in the form of insulating boards, which are introduced between two mutually opposing mounting elements 1.

Die beiden unmittelbar zu den U-förmigen Abschnitten 4 benachbarten Winkelprofile 3 weisen an ihrem unteren Ende ein Befestigungsblech 14 zur Befestigung des Halterungselements 1 auf einer Schalungssohle auf. Das Befestigungsblech 14 ist am unteren Rand des Winkelprofils 3 angeschweißt.The two immediately adjacent to the U-shaped sections 4 angle sections 3 have at their lower end a mounting plate 14 for fixing the support member 1 on a formwork sole. The mounting plate 14 is welded to the lower edge of the angle section 3.

Mit Hilfe der erfindungsgemäßen Halterung lassen sich beispielsweise die Kellerwände benachbarter Gebäude in einem Arbeitsgang gießen und gleichzeitig wasserundurchlässig miteinander unter Ausbildung einer Fuge 19 zwischen den aneinander grenzenden Kellerwänden verbinden. Für die nachfolgenden Erläuterungen wird die Kellerwand des ersten Gebäudes als erster Betonierungsabschnitt 15 und die Kellerwand des zweiten Gebäudes als zweiter Betonierungsabschnitt 16 bezeichnet. Zunächst wird auf einer Seite der Betonierungsabschnitte 15, 16 eine erste Schalhaut 17 errichtet.With the help of the holder according to the invention, for example, the basement walls of adjacent buildings pour in a single operation and at the same time connect waterproof with each other to form a gap 19 between the adjoining basement walls. For the following explanations, the basement wall of the first building is referred to as the first concreting section 15 and the basement wall of the second building as the second concreting section 16. First, a first formwork skin 17 is erected on one side of the concreting sections 15, 16.

Sodann wird ein erstes Halterungselement 1, wie es in Figur 1 dargestellt ist, mit den Befestigungsblechen 14 auf die Schalungssohle aufgesetzt, wobei die U-förmigen Abschnitte 4 rechtwinkelig zum Verlauf der herzustellenden Fuge 19 ausgerichtet werden. Wie aus Figur 2 erkennbar, erstrecken sich die Flachstahl-Profile 2 einschließlich der Abstandshalter 12,13 über die gesamte Dicke der Betonierungsabschnitte 15, 16. Nach dem Ausrichten des ersten Halterungselementes 1 wird dieses auf der Schalungssohle beispielsweise mittels Schrauben befestigt.Then, a first support member 1, as shown in Figure 1, placed with the mounting plates 14 on the formwork sole, the U-shaped portions 4 are aligned perpendicular to the course of the joint 19 to be produced. As can be seen from FIG. 2, the flat steel profiles 2, including the spacers 12, 13, extend over the entire thickness of the concreting sections 15, 16. After the alignment of the first Retaining element 1, this is fastened on the formwork sole, for example by means of screws.

Das insgesamt mit 8 bezeichnete Fugenband ist mit seinem unteren Rand quer zum verlauf der Fuge 19 in die Schalungssohle eingegossen. Es besteht im Ausführungsbeispiel aus einem extrudierten Profilstrang aus Kunststoff. Bei dem dargestellten Fugenband 8 handelt es sich um ein sogenanntes Dehnungsfugenband mit einem im Bereich der betonfreien Fuge 19 angeordneten Mittelschlauch 21, von dem aus sich in entgegengesetzter Richtung seitlich zwei Seitenbahnen 7 a, b erstrecken. Selbstverständlich lässt sich die erfindungsgemäße Halterung jedoch auch bei sogenannten Arbeitsfugenbändern ohne Mittelschlauch verwirklichen. Die Seitenbahnen 22 a, b besitzen in ihrem Flächenbereich mehrere Rippen.The total designated 8 joint tape is cast with its lower edge transverse to the course of the joint 19 in the formwork sole. It consists in the embodiment of an extruded profile strand of plastic. In the illustrated joint tape 8 is a so-called expansion joint tape with a arranged in the region of the concrete-free joint 19 center hose 21 from which laterally two side panels 7 a, b extend in the opposite direction. Of course, the holder according to the invention, however, can also be realized in so-called working joint bands without middle tube. The side panels 22 a, b have in their surface area a plurality of ribs.

Nach dem Befestigen des ersten Halterungselementes 1 auf der Schalungssohle wird die in Figur 2 linke Seitenbahn 7 a in die von den U-förmigen Abschnitten 4 gebildete Aufnahme des Halterungselementes 1 seitlich eingeschoben. Der Bereich zwischen dem Fugenband 8 und der bereits errichteten ersten Schalhaut 17 wird sodann mit Dämmplatten aufgefüllt, deren Dicke etwa der geforderten Fugenbreite 25 entspricht.After attaching the first support member 1 on the formwork sole the left side panel 7 a in FIG. 2 is laterally inserted into the receptacle of the support element 1 formed by the U-shaped sections 4. The area between the joint tape 8 and the already erected first formwork skin 17 is then filled with insulation boards whose thickness corresponds approximately to the required joint width 25.

Anschließend wird das zweite Halterungselement 1 in gleicher Weise auf der Schalungssohle ausgerichtet und die Seitenbahn 7 b des Fugenbandes 8 in dem gegenüberliegenden U-förmigen Abschnitt 4 des zweiten Halterungselementes 1 aufgenommen. Anschließend wird das Halterungselement 1 auf der Schalungssohle verschraubt. Nach Aufstellen des zweiten Halterungselementes 1 wird der durch die längeren geraden Abschnitte 6 der Flachstahl-Profile 2 der sich gegenüberstehenden Halterungselemente 1 und das Fugenband 18 begrenzte Bereich ebenfalls mit Dämmplatten 26 aufgefüllt. Die Dämmplatten 26 werden dabei so konfenktioniert, dass deren Dicke der geforderten Fugenbreite 25 entspricht und dass sie bis an eine zweite Schalhaut 27 heranreichen, die anschließend errichtet wird.Subsequently, the second support member 1 is aligned in the same way on the formwork sole and the side panel 7 b of the joint strip 8 is received in the opposite U-shaped section 4 of the second support member 1. Subsequently, the support member 1 is bolted to the formwork sole. After setting up the second support member 1 of the longer straight sections 6 of the flat steel profiles 2 of the opposing support members 1 and the joint tape 18 limited area is also filled with insulation boards 26. The insulation boards 26 are konfenktioniert so that whose thickness corresponds to the required joint width 25 and that they come close to a second formwork skin 27, which is then built.

Schließlich werden die durch die Dämmplatten 26 in der Fuge 19 getrennten Betonierungsabschnitte 15, 16 vorzugsweise gleichzeitig oder unmittelbar nacheinander mit Beton verfüllt, der unter Einschluss der Seitenbahnen 7a, 7b des Fugenbandes 8 sowie der Halterungselemente 1 aushärtet.Finally, the concreting sections 15, 16 separated by the insulating panels 26 in the joint 19 are preferably filled simultaneously or immediately one after the other with concrete which hardens, including the side panels 7a, 7b of the joint strip 8 and the support elements 1.

Nach dem Entfernen der Schalung befindet sich das Fugenband 8 in einwandfreier Lage quer zu der Fuge 19 und erstreckt sich von der Schalungssohle über die gesamte Länge des gestreckten Fugenbandes. Die preiswerten Halterungselemente 1 werden als verlorene Bauteile mit einbetoniert.After removal of the formwork, the joint tape 8 is in perfect position transverse to the joint 19 and extends from the formwork sole over the entire length of the elongated joint strip. The inexpensive support elements 1 are cast in as lost components.

Die Verwendung der erfindungsgemäßen Anordnung zur Halterung für das Fugenband ermöglicht nicht nur die zeitgleiche oder zeitnah aufeinanderfolgende Betonierung der beiden Betonierungsabschnitte, sondern darüber hinaus die Einbringung eines Fugenbandes sowie einer Schalldämmung zwischen den beiden Betonierungsabschnitten in einem einzigen dem Betonieren vorausgehenden Arbeitsschritt.The use of the arrangement according to the invention for holding the joint tape allows not only the simultaneous or timely successive concreting of the two concreting sections, but also the introduction of a joint tape and a sound insulation between the two concreting sections in a single concreting the preceding step.
