Description
Die Erfindung betrifft eine Fugenausbildung in einem Ortbetonbauwerk, das zur Vermeidung von Rissebildungen in Abschnitten hergestellt wird und bei dem aus den einzelnen Bauwerksabschnitten Bewehrungen in die später auszubetonierenden Fugen zwischen den Abschnitten einbinden.The invention relates to a joint formation in an in-situ concrete structure, which is made in sections to avoid cracks and where Reinforcements from the individual building sections to those to be concreted later Include joints between the sections.
Es ist schon bekannt, Ortbetonbauwerke zur Vermeidung von Rißbildungen, insbesondere von Schwindrissen, in Abschnitten herzustellen, wobei diese Abschnitte durch Fugen voneinander getrennt sind, in welche Bewehrungen aus diesen einbinden. Diese bisher übliche Ausbildungsart weist verschiedene Nachteile auf. Da die Fugen bis zum endgültigen Verguß aus Beton oder Mörtel als durchgehende Spalte offenbleiben, können sie während des Bauzustands keine abdichtende Funktion ausüben. Außerdem ist es erforderlich, die Fuge vor dem endgültigen Verguß beidseitig erneut einzuschalen, sofern nicht die ursprüngliche Schalung so lange an ihrem Ort belassen wird. Letzteres wird im allgemeinen nicht der Fall sein, da man die ursprüngliche Schalung normalerweise nicht über einen längeren Zeitraum von z. B. einigen Monaten belassen wird, so daß der erneute Arbeits- und Materialaufwand des Ein- und Ausschalens der Fuge erforderlich ist.It is already known to use in-situ concrete structures to avoid cracking, especially of shrinkage cracks, to be produced in sections, these sections are separated from each other by joints, in which reinforcements from these are incorporated. This previously common type of training has various disadvantages. As the joints remain open as a continuous gap until the final grouting of concrete or mortar, they cannot perform a sealing function during the construction phase. aside from that it is necessary to re-form the joint on both sides before the final grouting, unless the original formwork is left in place for so long. The latter will generally not be the case, as you would normally use the original formwork not for a long period of time, e.g. B. is left a few months so that the renewed work and material expenditure for shuttering and dismantling the joint is required is.
Die Aufgabe der Erfindung besteht darin, eine Fugenausbildung zu schaffen, die bereits während des Bauzustandes eine wasserabdichtende Funktion ausübt, bis zum endgültigen Verguß mit Beton oder Mörtel Bewegungen, z. B. infolge Schwinden, zur Vermeidung von Rissebildungen im Bauwerk zuläßt und ein zusätzliches Einschalen der Außenflächen zum Einbringen des Vergußbetons nicht benötigt.The object of the invention is to create a joint formation, which already has a waterproofing function during the construction phase, until for final grouting with concrete or mortar movements, e.g. B. as a result of shrinkage, to avoid the formation of cracks in the structure and an additional shuttering the outer surfaces for pouring the grouting concrete is not required.
Die Lösung der gestellten Aufgabe erfolgt bei einer Fugenausbildung der eingangs beschriebenen Art dadurch, daß sich die Fugenbreite im Querschnitt zumindest zu einem Rand hin, in dem ein Fugenblech oder Fugenband angeordnet ist, verringert.The task at hand is solved with a joint formation of the type described in that the joint width in cross section at least towards one edge in which a joint plate or joint tape is arranged, decreased.
Es ist zweckmäßig, die Schalung für die Fugenleibungen aus im Bauwerk verbleibendem Streckmetall od. dgl. zu bilden.It is advisable to use the formwork for the joint reveals in the building remaining expanded metal or the like. To form.
Die Verbindung zwischen dem Fugenband und der Schalung wird erleichtert, wenn das Fugenband Wulste aufweist, an denen die im Bauwerk verbleibende Schalung befestigt werden kann.The connection between the joint tape and the formwork is facilitated, if the joint tape has beads on which the formwork remaining in the structure can be attached.
Die Bewehrungsführung innerhalb der Fuge erfolgt zweckmäßigerweise schlaufenförmig, wobei die freien Enden jeweils in den benachbarten Bauwerksabschnitten einbinden.. _ Ein Vorteil der beschrieenen Fugenausbildung liegt darin, daß die Fuge bereits im Bauzustand, also vor dem endgültigen Verguß eine wasserabdichtende Funktion übernehmen kann. Bei Verwendung von wasserdichtem Beton kann mittels dieser Fugenausbildung auf eine Dichtungswanne verzichtet werden, zumindest kann, sofern das Bauwerk im Grundwasser liegt, die Dauer der Wasserhaltung verringert werden. Ein weiterer Vorteil besteht darin, daß zum Einbringen des endgültigen Vergusses die Außenseiten der Fugen nicht erneut eingeschaltet zu werden brauchen.The reinforcement routing within the joint is expedient loop-shaped, with the free ends in the adjacent building sections incorporate .. _ One advantage of the joint design described is that the Joint already in the construction stage, i.e. a waterproof one before the final grouting Function. When using waterproof concrete, this can be used Joint formation on a sealing trough can be dispensed with, at least, provided that the structure is in the groundwater, the duration of dewatering can be reduced. Another advantage is that it allows for the final potting the outsides of the joints do not need to be switched on again.
In der Zeichnung sind zwei Ausführungsbeispiele der erfindungsgemäßen Fugenausbildung dargestellt. Es zeigt F i g.1 einen Querschnitt durch die Decke bzw. Sohle eines Bauwerks und F i g. 2 einen Horizontalschnitt der Fugenausbildung in einer Wand.-Im unteren Teil der Fuge gemäß F i g.1 verringert sich der Querschnitt zum Rand hin, und es befindet sich an dieser Stelle ein Fugenblech 1, welches mit den benachbarten Bauwerksabschnitten verbunden ist. An das Fugenblech 1 schließt eine im Bauwerk verbleibende Schalung 2 aus Streckmetall an, welche die Fugenleibung bildet. Innerhalb des durch die Schalungen 2 gebildeten Fugenraumes liegt die Stoßbewehrung 3, welche innerhalb der Fuge schlaufenförmig ausgebildet ist und mit den freien Enden jeweils in die benachbarten Bauwerksabschnitte einbindet.In the drawing, two exemplary embodiments of the joint design according to the invention are shown. FIG. 1 shows a cross section through the ceiling or floor of a building, and FIG. 2 shows a horizontal section of the joint formation in a wall. In the lower part of the joint according to FIG. 1, the cross-section decreases towards the edge, and at this point there is a joint plate 1, which is connected to the adjacent building sections. A formwork 2 made of expanded metal, which remains in the structure and forms the joint reveal, adjoins the joint plate 1. Within the joint space formed by the formwork 2 lies the butt reinforcement 3, which is designed in the shape of a loop within the joint and integrates with the free ends into the adjacent building sections.
Bei der in F i g. 2 gezeigten Fugenausbildung in einer Wand verjüngt sich die Fuge zu den beiden Rändern hin. An jedem Rand ist ein Fugenband 4 angeordnet, das zur Befestigung mit der Leibungsschalung in Längsrichtung verlaufende Wulste 5 aufweist. Innerhalb der im Bauwerk verbleibenden Schalungen 6 befinden sich die schlaufenförmig gebogenen Stoßbewehrungen 7.In the case of the in FIG. 2 shown joint formation in a wall, the joint tapers towards the two edges. At each edge a joint tape 4 is arranged, which has beads 5 extending in the longitudinal direction for attachment to the reveal formwork. The butt reinforcements 7, which are bent in the shape of a loop, are located within the formwork 6 remaining in the building.
