Description

Die Erfindung bezieht sich auf ein Schalungselement der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a formwork element explained in the preamble of claim 1 Art.

Ein derartiges Schalungselement ist beispielsweise aus der EP-A-532908 bekannt. Beim bekannten Schalungselement werden zwei in der gleichen Ebene, aber mit Abstand nebeneinander liegende Schalungswandungen über eine korbartige Bügelkonstruktion miteinander verbunden, die an beiden Seiten der Schalungswandungen vorsteht. In diese korbartige Bügelkonstruktion werden Fugensperren, beispielsweise in Form eines elastischen Fugenbandes, eingelegt und ggf. durch Zusammenbiegen der Schenkel der Bügelkonstruktion formschlüssig fixiert. Eine derartige Halterung eignet sich besonders für elastische Fugenbänder, die in ihrer Längsmittellinie mit vorspringenden Rippen versehen sind, mit denen ihre Lage in der Bügelkonstruktion seitlich fixiert werden kann.Such a formwork element is for example from the EP-A-532 908 known. In the known formwork element two in the same plane, but at a distance adjacent formwork walls are connected to each other via a basket-like bow construction, which projects on both sides of the formwork walls. In this basket-like bow construction grout locks, for example in the form of an elastic joint tape, inserted and possibly positively fixed by bending the legs of the bracket construction. Such a holder is particularly suitable for elastic joint tapes, which are provided in their longitudinal center line with projecting ribs with which their position in the bracket construction can be fixed laterally.

Aus der EP-A-513740 ist ein weiteres Schalungselement bekannt, das speziell für die Halterung eines Fugenbleches ausgebildet ist. Dabei wird das Fugenblech direkt zwischen die beiden Schalungswandungen eingeschweißt, so dass es sich rechtwinklig dazu erstreckt und beidseitig der Schalungswandungen vorsteht. Es ist jedoch nicht immer möglich, Fugenbleche zu verschweißen, beispielsweise wenn diese beschichtet sind oder aus nicht schweißbarem Materialien bestehen.From the EP-A-513 740 is another formwork element is known, which is specially designed for holding a joint plate. In this case, the joint plate is welded directly between the two formwork walls, so that it extends at right angles to it and projecting on both sides of the shuttering walls. However, it is not always possible to weld joint plates, for example if they are coated or consist of non-weldable materials.

Der Erfindung liegt die Aufgabe zugrunde, ein Schalungselement mit einer einfachen und sicheren Halterung für eine Fugensperre bereitzustellen, das sich besonders für die Verwendung von Fugenblechen eignet.The invention has for its object to provide a formwork element with a simple and secure support for a joint barrier, which is particularly suitable for the use of joint plates.

Die Aufgabe wird durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die erfindungsgemäße Ausgestaltung können Fugensperren der unterschiedlichsten Art auf einfache Weise mit den Schalungswandungen verbunden werden, ohne dass ein Verschweißen notwendig wäre. Deshalb eignet sich die Erfindung auch besonders zur Halterung von Fugenblechen, die entweder beschichtet und/oder aus einem nicht schweißbaren Material bestehen. Aber auch Fugenbänder aus Elastomermaterialien können auf die erfindungsgemäße Weise mit den Schalungswandungen in einer vorbestimmten Ausrichtung verbunden werden.Due to the configuration of the invention, joint barriers of various kinds can be easily connected to the formwork walls, without welding would be necessary. Therefore, the invention is also particularly suitable for mounting joint plates, which are either coated and / or made of a non-weldable material. But also joint tapes of elastomeric materials can be connected in the manner according to the invention with the formwork walls in a predetermined orientation.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

Für die Erfindung sind die verschiedensten Klemm-Mittel einsetzbar, mit denen eine Fugensperre kraftschlüssig klemmend fixierbar ist.For the invention, a variety of clamping means are used, with which a joint barrier is frictionally clamped fixable.

Bevorzugt erfolgt die kraftschlüssige, klemmende Fixierung durch eine Klemmeinrichtung, die beispielsweise Teil der Verbindungseinrichtung sein kann, mit denen die Schalungswandungen über den dazwischen liegenden Spalt miteinander verbunden werden. Zusätzlich oder alternativ kann die kraftschlüssige, klemmende Fixierung der Fugensperre auch durch das Schalungsmaterial selbst erfolgen, das bevorzugt in Randbereichen elastisch ausgebildet, beim Einschieben der Fugensperre ausgelenkt und sich durch Federeigenschaften an die Fugensperre haltend anlegt. Die Klemm-Mittel der Verbindungseinrichtung können in unterschiedlicher Weise ausgebildet sein. Bevorzugt enthält die Verbindungseinrichtung einen Bügel mit federnden Schenkeln, wobei die Schenkel die Klemm-Mittel für die Fugensperre bilden.Preferably, the non-positive, clamping fixation by a clamping device, which may be part of the connection means, for example, with which the formwork walls are connected to each other via the gap therebetween. Additionally or alternatively, the non-positive, clamping fixation of the joint barrier can also be done by the formwork material itself, which preferably formed elastically in edge regions, deflected when inserting the joint barrier and retains holding by spring properties of the joint barrier. The clamping means of the connecting device can be designed in different ways. Preferably, the connecting device includes a bracket with resilient legs, wherein the legs form the clamping means for the joint barrier.

Zum Klemmen wird bevorzugt ein federndes Element eingesetzt, das an der Verbindungseinrichtung angeordnet ist bzw. Teil der Verbindungseinrichtung ist.For clamping, a resilient element is preferably used, which is arranged on the connecting device or is part of the connecting device.

Um eine lagegenaue Positionierung der Fugensperre zu erreichen, ist bevorzugt ein Tiefenanschlag vorgesehen, der die Einsetztiefe der Fugensperre in den Spalt begrenzt.In order to achieve a positionally accurate positioning of the joint barrier, a depth stop is preferably provided which limits the depth of insertion of the joint barrier in the gap.

Die Verbindungseinrichtung besteht aus einer Vielzahl im Abstand zueinander mit beiden Schalungswandungen verbundenen Bügeln, die über eine Verstrebung miteinander verbunden sind. Diese Verstrebung kann bevorzugt als Tiefenanschlag ausgebildet sein. Weiterhin kann durch die Verstrebung der Abstand zweier Schenkel des Bügels festgelegt werden, der dem gewünschten Klemmabstand entspricht.The connecting device consists of a plurality of spaced apart with two formwork walls connected brackets, which are connected to one another via a brace. This bracing may preferably be designed as a depth stop. Furthermore, the distance between two legs of the bracket can be determined by the brace, which corresponds to the desired clamping distance.

Die Bügel können als Einzelbügel ausgebildet sein, können jedoch auch an einem mit der Schalungswandung verbundenen Versteifungsträger angeordnet sein.The brackets may be formed as a single bracket, but may also be arranged on a stiffening carrier connected to the formwork wall.

Fig. 1 zeigt ein erstes Ausführungsbeispiel eines erfindungsgemäßen Schalungselementes 1, das bevorzugt als Fugenschalungselement und bevorzugt als verlorenes Schalungselement ausgebildet ist, d.h. im Beton verbleibt. Das Schalungselement 1 enthält zwei Schalungswandungen 2, die für Fugenschalungen streifenförmig ausgebildet sind, dies jedoch nicht sein müssen. Die Schalungswandungen 2 sind beidseitig eines Spaltes 3 angeordnet, und liegen sich im dargestellten Ausführungsbeispiel in der gleichen Ebene gegenüber. Der Spalt 3 erstreckt sich über die gesamte Länge der Schalungswandungen 2 und wird in einer vorbestimmten Breite b durch eine Verbindungseinrichtung 4 fixiert, die mit beiden Schalungswandungen 2 fest verbunden ist. Fig. 1 shows a first embodiment of a formwork element 1 according to the invention, which is preferably designed as a joint formwork element and preferably as a lost formwork element, ie, remains in the concrete. The formwork element 1 contains two formwork walls 2, which are strip-shaped for joint formwork, but this need not be. The Formungswandungen 2 are arranged on both sides of a gap 3, and are in the illustrated embodiment in the same plane opposite. The gap 3 extends over the entire length of the formwork walls 2 and is fixed in a predetermined width b by a connecting device 4, which is fixedly connected to two shuttering walls 2.

Die Schalungswandungen 2 können aus jedem geeigneten Schalungsmaterial bestehen, sind jedoch bevorzugt aus Metall, so dass eine ebenfalls aus Metall bestehende Verbindungseinrichtung 4 in einfacher Weise mit den Schalungswandungen 2 verschweißt werden kann. Bevorzugt ist das Material der Schalungswandungen 2 begrenzt betondurchlässig, um eine raue Anschlussfläche zu gewährleisten. Ein bevorzugtes Material für die Schalungswandungen 2 ist Streckmetall in jeder bekannten Ausführung.The formwork walls 2 may consist of any suitable formwork material, but are preferably made of metal, so that a likewise made of metal connecting device 4 can be welded to the formwork walls 2 in a simple manner. Preferably, the material of the formwork walls 2 is limited concrete permeable to ensure a rough connection surface. A preferred material for the formwork walls 2 is expanded metal in any known design.

Die Verbindungseinrichtung 4 enthält im dargestellten Ausführungsbeispiel eine Mehrzahl von Bügeln 5, die mit Abstand zueinander entlang des Spaltes 3 angeordnet sind.The connecting device 4 includes in the illustrated embodiment, a plurality of brackets 5, which are arranged at a distance from each other along the gap 3.

Wie auch in Verbindung mit Fig. 2 ersichtlich, weist jeder Bügel 5 bevorzugt eine im Wesentlichen omegaförmige Gestalt auf, wobei zumindest zwei erste Schenkel 5a vorgesehen sind, die am Spalt 3 anliegen, sich im Wesentlichen rechtwinklig zur Ebene des Spaltes 3 erstrecken und über einen vorbestimmten Bereich K parallel zueinander verlaufen. Beide Schenkel 5a weisen einen Abstand zueinander auf, der im Wesentlichen der Breite b des Spaltes 3 entspricht.As well as in connection with Fig. 2 it can be seen, each bracket 5 preferably has a substantially omega-shaped shape, wherein at least two first legs 5a are provided, which abut the gap 3, extend substantially perpendicular to the plane of the gap 3 and extend over a predetermined range K parallel to each other. Both legs 5a have a distance from one another, which corresponds essentially to the width b of the gap 3.

Der Bügel 5 weist weiterhin Befestigungseinrichtungen in Form zweiter Schenkel 5b auf, die sich im Wesentlichen parallel zur Schalungswandung 2 erstrecken und an dieser fixiert, bevorzugt angeschweißt, sind. Im dargestellten Ausführungsbeispiel erstrecken sich die zweiten Schenkel 5b über die gesamte Breite jeder Schalungswandung 2.The bracket 5 further comprises fastening means in the form of second legs 5b, which extend substantially parallel to the shuttering wall 2 and fixed thereto, preferably welded, are. In the illustrated embodiment, the second leg 5b extend over the entire width of each formwork wall second

Der Übergang zwischen den ersten und zweiten Schenkeln 5a, 5b ist mit einer Ausrundung R versehen, durch den sich die Schenkel 5a, 5b etwas von der jeweils anliegenden Schalungswandung 2 abheben.The transition between the first and second legs 5a, 5b is provided with a fillet R, through which the legs 5a, 5b lift slightly from the respective adjacent formwork wall 2.

Die Schenkel 5a, 5b jeder Seite des Bügels 5 werden über einen Verbinder, z. B. einen Verbindungsbogen 5c miteinander verbunden. Der Bügel 5 wird bevorzugt mit den Schenkeln 5a, 5b und dem Verbindungsbogen 5c aus einem Metallstab gebogen.The legs 5a, 5b each side of the bracket 5 are connected via a connector, for. B. a connecting sheet 5c connected to each other. The bracket 5 is preferably bent with the legs 5a, 5b and the connecting sheet 5c of a metal rod.

Die Vielzahl der Bügel 5 des Schalungselementes 1 wird über eine im Wesentlichen parallel zum Spalt 3 verlaufende Verbindungsstrebe 6 miteinander verbunden und im vorbestimmten Abstand entlang des Spaltes 3 gehalten, wobei die Verbindungsstrebe 6 als Metallstab ausgebildet und bevorzugt am Übergang zwischen den ersten Schenkeln 5a und der Verbindung 5c mit den Bügeln 5 verschweißt ist. Die Verstrebung 6 ist bevorzugt so angeordnet, dass sie die beiden Schenkel 5a in einem Abstand zueinander hält, der bevorzugt etwa gleich der Breite b des Spaltes 3 und kleiner als eine vorbestimmte Dicke d einer handelsüblichen Fugensperre 7 ist. Die Verstrebung 6 befindet sich senkrecht zur Ebene des Spaltes 3 und in einem Abstand zu diesem, der etwa der halben Breite der Fugensperre 7 (Fig. 2) entspricht, die im dargestellten Ausführungsbeispiel als Fugenblech mit übertrieben gezeichneter Dicke d dargestellt ist, um die Darstellung klarer zu machen. Die Fugensperre 7 bzw. das Fugenband ist handelsüblich und weist eine handelsübliche Dicke d auf.The plurality of brackets 5 of the formwork element 1 is connected to one another via a substantially parallel to the gap 3 extending connecting strut 6 and held at a predetermined distance along the gap 3, wherein the connecting strut 6 formed as a metal rod and preferably at the transition between the first legs 5a and Compound 5c is welded to the straps 5. The strut 6 is preferably arranged so that it holds the two legs 5a at a distance from each other, which is preferably approximately equal to the width b of the gap 3 and smaller than a predetermined thickness d of a commercial joint seal 7. The strut 6 is perpendicular to the plane of the gap 3 and at a distance to this, which is about half the width of the joint barrier 7 (FIG. Fig. 2 ), which is shown in the illustrated embodiment as a joint plate with exaggerated drawn thickness d to make the presentation clearer. The joint seal 7 or the joint tape is commercially available and has a commercial thickness d.

Die Dicke d der Fugensperre 7 ist größer als die Breite b des Spaltes 3 und somit auch größer als der Abstand zwischen den beiden Schenkeln 5a jedes Bügels 5. Die Breite b und der Abstand zwischen den Schenkeln 5a bildet somit einen Klemmabstand AK, in die die Fugensperre 7 unter elastisch federnder Verdrängung der anliegenden Elemente eingedrückt wird. Der Klemmabstand AK kann so gewählt werden, dass alle oder zumindest eine Mehrzahl handelsüblicher Dicken d abgedeckt werden.The thickness d of the joint barrier 7 is greater than the width b of the gap 3 and thus larger than the distance between the two legs 5a of each bracket 5. The width b and the distance between the legs 5a thus forms a clamping distance A K , in the the joint barrier 7 is pressed under elastically resilient displacement of the adjacent elements. The clamping distance A K can be chosen so that all or at least a plurality of commercially available thicknesses d are covered.

Beim Einschieben der Fugensperre 7 werden Randbereiche 2a der Schalungswandungen 2, die in der Nähe oder direkt anliegend zum Spalt 3 liegen, um die Ausrundungen R gebogen und klemmen kraftschlüssig die Fugensperre 7 durch ihre Rückfederkraft. Weiterhin werden die Schenkel 5a auseinander gedrückt, wobei auch dadurch die Fugensperre 7 durch die Rückstellkraft der federnden Ausbiegung der Verbindungseinrichtung 4 und insbesondere der Schenkel 5a der Bügel 5 kraftschlüssig federnd fixiert werden kann.When inserting the joint barrier 7 edge portions 2 a of Schal formwandungen 2, which are in the vicinity or directly adjacent to the gap 3, bent around the fillets R and clamp the Fugensperre 7 force-locking by their return spring force. Furthermore, the legs 5a are pressed apart, thereby also the joint barrier 7 by the restoring force of the resilient deflection of the connecting device 4 and in particular the legs 5a of the bracket 5 can be fixed non-positively resilient.

Im Gebrauch des erfindungsgemäßen Schalungselementes kann somit das Schalungselement mit den Schalungswandungen und der Verbindungseinrichtung 4 werkseitig fertiggestellt und auf die Baustelle geliefert werden. Dort wird unter elastischer Verformung die Fugensperre 7, also beispielsweise ein handelsübliches Fugenblech, in den Spalt 3 eingedrückt, wodurch zunächst die Schalungswandungen 2 um den Radius R verformt und anschließend die Schenkel 5a elastisch federnd auseinander gedrückt werden, so dass bevorzugt über die gesamte Erstreckung K der Schenkel 5a eine Klemmkraft auf die Fugensperre 7 aufgebracht werden kann. Die Verstrebung 6 wirkt dabei als Tiefenanschlag, der das Einschieben der Fugensperre 7 begrenzt.In use of the formwork element according to the invention thus the formwork element can be completed with the formwork walls and the connecting device 4 factory and delivered to the site. There, under elastic deformation, the joint seal 7, so for example, a commercial joint plate, pressed into the gap 3, whereby initially the formwork walls 2 deformed by the radius R and then the legs 5a are pressed resiliently apart so that preferably over the entire extension K of the legs 5a, a clamping force can be applied to the joint barrier 7. The brace 6 acts as a depth stop, which limits the insertion of the joint barrier 7.

Fig. 3 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Schalungselementes 10, das bis auf die nachfolgend beschriebenen Abwandlungen dem Schalungselement 1 entspricht, so dass gleiche bzw. vergleichbare Bauteile mit den gleichen Bezugszeichen gekennzeichnet und nicht nochmals erläutert sind. Fig. 3 shows a further embodiment of a formwork element 10 according to the invention, which corresponds to the formwork element 1 except for the modifications described below, so that identical or comparable components are marked with the same reference numerals and are not explained again.

Das Schalungselement 10 unterscheidet sich vom Schalungselement 1 lediglich durch beidseitig angeordnete, zusätzliche Versteifungsträger 11, die die Verbindungseinrichtung 4 zusätzlich mit beiden Schalungswandungen 2 verbinden. Die Versteifungsträger 11 sind in Form herkömmlicher, flächiger Gitterträger ausgebildet und enthalten zwei parallel zueinander angeordnete Stäbe 12a und 12b, die durch zick-zack- oder bogenförmige Querstäbe 13 miteinander verbunden sind. Der erste Längsstab 12a wird beispielsweise an den Verbindern 5c der Bügel 5 und der zweite Längsstab 12b an der zugeordneten Schalungswandung 2 befestigt, bevorzugt verschweißt, so dass sich eine dachförmige Versteifung für die Verbindungseinrichtung 4 ergibt.The formwork element 10 differs from the formwork element 1 only by double-sided, additional stiffening support 11, which additionally connect the connecting device 4 with two shuttering walls 2. The stiffening beams 11 are in the form of conventional, flat lattice girders and contain two mutually parallel rods 12a and 12b, which are connected by zig-zag or arcuate transverse rods 13 with each other. The first longitudinal bar 12a is fastened, for example, to the connectors 5c of the brackets 5 and the second longitudinal bar 12b is fastened to the associated formwork wall 2, preferably welded, so that a roof-shaped reinforcement for the connecting device 4 results.

In Abwandlung der geschriebenen und gezeichneten Ausführungsbeispiele kann die kraftschlüssige Klemmung auch nur entweder durch die Randbereiche der Schalungswandungen oder durch die Verbindungseinrichtung, insbesondere deren Bügel, erfolgen. Unter Umständen kann es ausreichend sein, nur einen der Randbereiche elastisch abbiegbar auszubilden. Auch müssen die Klemmabstände im Bereich der Verbindungseinrichtung und im Bereich des Spaltes nicht unbedingt gleich breit sein. Es ist weiterhin möglich, eine Klemmung außerhalb der Verbindungseinrichtung durch eine externe und/oder mit der Verbindungseinrichtung verbundene Klemmeinrichtung vorzusehen. Die Schenkel der Bügel müssen nicht unbedingt linienförmigen Kontakt über ihre gesamte Länge mit der Fugensperre aufweisen, vielmehr können sie auch schräg zur Fugensperre verlaufen und nur über einen kleinen Bereich ihrer Länge, beispielsweise durch eine Ausbiegung, in Klemmkontakt mit der Fugensperre stehen. Die Klemm-Mittel können weiterhin ein gesondertes Federelement enthalten, das nicht Teil der Verbindungseinrichtung ist.In a modification of the written and drawn embodiments, the non-positive clamping can only be done either by the edge regions of the formwork walls or by the connecting device, in particular their bracket. Under certain circumstances, it may be sufficient to form only one of the edge regions elastically bendable. Also, the clamping distances in the region of the connecting device and in the region of the gap need not necessarily be the same width. It is also possible to provide a clamping outside the connecting device by an external and / or connected to the connecting device clamping device. The legs of the bracket must not necessarily have linear contact over their entire length with the joint barrier, but they can also run obliquely to the joint barrier and only over a small portion of their length, for example, by a deflection, are in clamping contact with the joint barrier. The clamping means may further comprise a separate spring element which is not part of the connecting device.
