Abstract

A shuttering element (1) for joints in concrete constructions is described, having two sheet-like shuttering parts (2a, 2b) and, lying in between and fastened on the shuttering parts (2a, 2b), a securing means (3) for a joint strip (water bar) (7). In order to be able to handle such a shuttering element (1) for joints better and more easily and for production to be simple, it is proposed to provide a cage-like bow construction (3) as the securing means. The cage-like bow construction (3) has two legs (3a, 3b) which extend transversely with respect to the shuttering parts (2a, 2b) and are connected to each other. In each case one of the legs (3a, 3b) is connected to in each case one of the shuttering parts (2a, 2b). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Fugenschalungselement für Betonkonstruktionen.The invention relates to a joint formwork element for concrete structures.

Ein Fugenschalungselement für Betonkonstruktionen ist aus der DE-A-1 259 546 bekannt. Die Halterung für das Fugenband des bekannten Fugenschalungselementes besteht jeweils aus wenigstens zwei Teilen, wobei jeweils eines der Halterungsteile mit einem plattenförmigen Schalungsteil aus Streckmetall verbunden wurde. In einem Ausführungsbeispiel wird das Fugenband durch formschlüssige Anpassung jeder der beiden Halterungsteile an eine mittige Verdickung des Fugenbandes gehalten. Durch die Elastizität der meist aus Gummi bestehenden Fugenbänder können sich die Schalungstafeln jedoch ohne weiteres aus ihrer fluchtenden Ausrichtung verdrehen, so dass sie einen spitzen bzw. stumpfen Winkel miteinander einschließen. Dies erschwert die Arbeit mit dem bekannten Fugenschalungselement.A joint formwork element for concrete structures is from DE-A-1 259 546 known. The holder for the joint tape of the known joint formwork element consists of at least two parts, one of the mounting parts was connected to a sheet-like formwork part made of expanded metal. In In one embodiment, the joint tape is made by positive adjustment each of the two mounting parts to a central thickening of the joint tape held. Due to the elasticity of the joint tapes, which are usually made of rubber the formwork panels can easily move out of alignment twist so that they make an acute or obtuse angle with each other lock in. This makes working with the known joint formwork element more difficult.

In einem weiteren Ausführungsbeispiel bestehen die Halterungsteile aus vier winkelförmigen Leisten, wobei zwei der Leisten an den Schalungsteilen befestigt sind und die beiden anderen Leisten als Gegenlager wirken, und durch Schrauben oder Nieten unter Einschluss eines mittigen Quersteges des Fugenbandes an den Leisten der Schalungsteile befestigt werden. Dieses Ausführungsbeispiel ist relativ aufwendig herzustellen und darüber hinaus trotzdem nicht gegen ein Verwinkeln seiner beiden Schalungsteile und Zusammendrücken des Fugenbandes geschützt.In a further embodiment, the mounting parts consist of four angular ones Strips, with two of the strips attached to the formwork parts and the other two strips act as counter bearings, and by screws or Rivets including a central crossbar of the joint tape on the strips the formwork parts are attached. This embodiment is relatively expensive to manufacture and, moreover, still not against a winking of his two Protected formwork parts and compression of the joint tape.

Das Lehrbuch Norbert Klawa, Alfred Haack "Tiefbaufugen", Ernst & Sohn, Verlag für Architektur und Technische Wissenschaften, Berlin, Copyright 1990, S. 249, Bild B 4/52 f und g zeigt eine Schlitzwandfuge, bei deren Herstellung der erste, dritte, fünfte Bewehrungskorb usw., der eingefahren wurde, an beiden Stirnseiten ein der Länge nach zweigeteiltes Fugenblech enthielt. Das Fugenblech übemimmt die Funktion einer Schalung der Stirnseite. Zwischen den beiden Fugenblechen ist ein steifes Elastomer-Fugenband eingebaut. Das Fugenband ist auf der freien Seite durch Bewehrungsstäbe gegen Beschädigungen, die beim Herablassen des anschließenden Bewehrungskorbes entstehen könnten, geschützt. Das Fugenband ist jedoch in dem als "Schutzkorb" bezeichneten Bauteil mit großem Abstand enthalten, und liegt auf der gegenüberliegenden Seite der Schalungsbleche seitlich frei und muss mit seinem freien Rand an einem Querstab der Hauptbewehrung angerödelt werden.The textbook Norbert Klawa, Alfred Haack "Tiefbaufugen", Ernst & Sohn, publisher for Architecture and Technical Sciences, Berlin, Copyright 1990, p. 249, image B 4/52 f and g shows a diaphragm wall joint, in the manufacture of which the first, third, fifth Reinforcement cage, etc., that has been retracted, on both ends one length after two-part joint sheet contained. The joint plate takes on the function of a Formwork of the face. There is a stiff between the two joint sheets Elastomer joint tape installed. The joint tape is on the free side through reinforcement bars against damage caused when lowering the subsequent Reinforcement cage could arise, protected. However, the joint tape is in that included as a "protective cage" component with a large distance, and lies on the opposite side of the formwork sheets laterally free and must with his free edge on a crossbar of the main reinforcement.

Ein Prospekt der Firma Amico Alabama Metal Industries Corp. "1989 Sweet's Catalogue File" zeigt den Aufbau einer Schalung aus Einzelteilen. Zum Aufbau der Schalung wird ein Träger aus sich kreuzenden und miteinander verschweißten Quer- und Längsstäben verwendet. Dieser Träger soll als wiederverwendbarer Formgeber und -halter für die flächigen Schalungsteile aus Streckmetall dienen, die für sich allein unter Wirkung des Betondruckes weder formhaltig noch standfähig sind. Mit diesem Träger soll somit ermöglicht werden, mit Streckmetall auch eine Nut-Feder-Anbindung benachbarter Betonkonstruktionen zu erreichen, die mit Streckmetall allein nicht auszuschalen wäre: Zu diesem Zweck enthält der Träger zusätzliche, mit jedem Querstab verschweißte Winkelstäbe, die die innere Kontur der Nut nachformen. Die flächigen Schalungsteile werden dann auf den Träger aufgelegt und mittels Draht in kurzen Abständen mit dem Träger verbunden (verrödelt), wobei die Drahtschlaufen einzeln wieder durchgeschnitten werden müssen, wenn eine Seite des Betons vergossen wurde, um den Träger wieder abnehmen zu können.A brochure from Amico Alabama Metal Industries Corp. "1989 Sweet's Catalog File "shows the construction of a formwork from individual parts Formwork becomes a girder made of intersecting and welded cross-members and longitudinal bars used. This carrier is intended to be a reusable form generator and -holder for the flat formwork parts made of expanded metal, which serve on their own are neither stable nor stable under the effect of the concrete pressure. With this Beams should thus be made possible, with expanded metal also a tongue and groove connection to achieve neighboring concrete structures using expanded metal alone would not be stripped: For this purpose, the carrier contains additional, with each cross bar welded angle bars that reshape the inner contour of the groove. The flat formwork parts are then placed on the support and by means of Wire connected to the carrier at short intervals (bridged), using the wire loops must be cut individually again if one side of the Concrete was poured in order to remove the carrier again.

Das Dichtungsband hingegen wird in gleicher Weise in die Abschalung integriert, wie dies bei bisherigen Schalungen ohne die Halterung gemäß dem angegriffenen Patent oder die Halterung gemäß dem nächstliegenden Stand der Technik, der DE 12 59 546, vorgenommen wurde, d.h. es wurde lediglich im Schalungsmaterial eine Lücke gelassen, in die das Fugenband gesteckt und so lang festgehalten wird, bis der erste Betonierabschnitt ausgehärtet ist. The sealing tape, however, is integrated in the formwork in the same way as this with previous formwork without the bracket according to the contested patent or the holder according to the closest prior art, DE 12 59 546, i.e. there was only a gap in the formwork material left, in which the joint tape is inserted and held until the first concrete section is cured.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Fugenschalungselement bereitzustellen, das einfach herzustellen und einfach zu handhaben ist.The invention is therefore based on the object of providing a joint formwork element, that is easy to manufacture and easy to use.

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

Durch die erfindungsgemäß vorgesehene korbartige Bügelkonstruktion wird eine starre Verbindung zwischen den beiden Schalungsteilen geschaffen und während der Schalungsarbeiten aufrechterhalten. Das Fugenband wird in die korbartige Bügelkonstruktion lediglich eingelegt und hat keinerlei Haltefunktion für den Zusammenhalt des Fugenschalungselementes.Due to the basket-like bracket construction provided according to the invention, a rigid connection between the two formwork parts created and during the formwork work. The joint tape is in the basket-like bracket construction just inserted and has no holding function for cohesion of the joint formwork element.

Besonders einfach ist das erfindungsgemäße Fugenschalungselement herzustellen, wenn die Bügelkonstruktion gemäß Anspruch 2 aus einer U-förmig gebogenen Gittermatte besteht.The joint formwork element according to the invention is particularly simple to manufacture, if the bracket construction according to claim 2 from a U-shaped curved mesh mat consists.

Durch die Maßnahme nach Anspruch 3 kann das Fugenband ohne weitere Befestigung in der Bügelkonstruktion gehalten werden.By the measure according to claim 3, the joint tape can be fastened without further are held in the bracket construction.

Für die Schalungsteile ist besonders gut das in Anspruch 4 beschriebene Material verwendbar, da dadurch die Teile des Fugenschalungselementes auf einfache Weise gegeneinander ausgerichtet und miteinander verschweißt werden können.For the formwork parts, the material described in claim 4 is particularly good usable, as this makes the parts of the joint formwork element simple aligned and welded together.

Zusätzlich können zur inneren Versteifung des Fugenschalungselements und zur weiteren Befestigung der Bügelkonstruktion die Winkelstäbe gemäß Anspruch 5 vorgesehen werden.In addition, the internal stiffening of the joint formwork element and further fastening the bracket construction, the angle bars according to claim 5 be provided.

Durch die Ausgestaltung nach Anspruch 6 wird si. chergestellt, daß das Fugenband in seiner gesamten Breite aufgespannt bleibt und sich beispielsweise nicht unter der Wirkung des Betondruckes abwinkelt.By the embodiment according to claim 6 si. made that the joint tape in its entire Width remains open and, for example, does not bent under the effect of the concrete pressure.

Durch die Ausgestaltung nach Anspruch 7 wird die Lagesicherung des Fugenbandes im Inneren der Bügelkonstruktion noch weiter verbessert.By the configuration according to claim 7 Securing the position of the joint tape inside the bracket construction improved even further.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 eine perspektivische, vereinfachte Darstellung des erfindungsgemäßen Fugenschalungselementes, und
  • Fig. 2 den Schnitt II/II aus Figur 1.
    • An embodiment of the invention is explained below with reference to the drawings. Show it:
  • Fig. 1 is a perspective, simplified representation of the joint formwork element according to the invention, and
  • 2 shows section II / II from FIG. 1.

    • Aus Figur 1 ist ein Fugenschalungselement 1 ersichtlich, das zwei aus Gründen der Übersichtlichkeit nur schematisch dargestellte, plattenförmige, rechteckige Schalungsteile 2a und 2b und eine dazwischenliegende, korbartige Bügelkonstruktion 3 als Halterung für ein aus Übersichtlichkeitsgründen in Figur 1 ebenfalls nicht gezeichnetes Fugenband zeigt. Die korbartige Bügelkonstruktion 3 besteht aus einem Bügelteil mit einem U-förmigen Querschnitt, das aus einer Gittermatte, bevorzugt einer Baustahlmatte, gebogen wurde. Das Bügelteil weist zwei Schenkel 3a und 3b auf, die sich querzur Ebene der Schalungsteile 2a, 2b erstrecken und mit jeweils einem der Schalungsteile verbunden sind. Die beiden Schenkel 3a, 3b sind untereinander über einen Steg 3c verbunden.A joint formwork element 1 can be seen from FIG. 1, the two only for reasons of clarity schematically shown, plate-shaped, rectangular Formwork parts 2a and 2b and an intermediate, basket-like bracket construction 3 as a holder for one For reasons of clarity in Figure 1 also not shown Joint tape shows. The basket-like frame construction 3 consists of a bracket part with a U-shaped Cross-section, made of a mesh mat, preferred a steel mesh, was bent. The bracket part has two legs 3a and 3b which are transverse to the plane the formwork parts 2a, 2b extend and with each one of the formwork parts are connected. The two Legs 3a, 3b are mutually via a web 3c connected.

    Wie Figur 2 zeigt, bestehen die Schalungsteile 2a und 2b jeweils aus einer Tafel 4 aus Streckmetall, auf deren beiden Oberflächen Metallstäbe 5 bzw. 6 aufgeschweißt sind. Sowohl die Metallstäbe 5 auf einer Oberfläche als auch die Metallstäbe 6 auf der anderen Oberfläche sind im Abstand und parallel zueinander angeordnet, wobei jedoch die Stäbe 5 auf einer der Oberflächen parallel zum Bügelteil und die Stäbe 6 auf der anderen Oberfläche der Streckmetalltafel 4 senkrecht zum Bügelteil verlaufen.As Figure 2 shows, the formwork parts 2a and 2b each from a sheet 4 made of expanded metal the two surfaces of which are welded metal rods 5 and 6, respectively are. Both the metal bars 5 on one surface as well as the metal bars 6 on the other surface are spaced and parallel to each other, however, the rods 5 on one of the surfaces parallel to the bracket part and the rods 6 on the other Surface of the expanded metal sheet 4 perpendicular to the bracket part run.

    Das Bügelteil ist derart mit den Schalungsteilen 2a, 2b verschweißt, daß die Schalungsteile 2a, 2b senkrecht und etwa in der Mitte der Schenkel 3a bzw. 3b des Bügelteiles auftreffen. Die Länge des Steges 3c sowie die Länge der Schenkel 3a, 3b des Bügelteiles sind derart auf die Abmessungen eines herkömmlichen Fugenbandes 7 aus Gummi oder dergleichen abgestimmt, daß das Fugenband 7 mindestens mit seiner gesamten Breite in das Innere des Bügelteiles versenkt werden kann und dort mittels Reibung seiner Verdickung an den Schenkeln 3a, 3b gehalten wird.The bracket part is so with the formwork parts 2a, 2b welded that the formwork parts 2a, 2b vertically and approximately in the middle of the legs 3a and 3b of the bracket part incident. The length of the web 3c and the Length of the legs 3a, 3b of the bracket part are such to the dimensions of a conventional joint tape 7 made of rubber or the like that the Joint tape 7 at least with its entire width in the inside of the bracket part can be sunk and there by friction of its thickening on the thighs 3a, 3b is held.

    Um zu verhindern, daß das Fugenband 7 beim Betoniervorgang aus der Bügelkonstruktion herausgeschoben wird, d.h. zur weiteren Lagesicherung des Fugenbandes 7, werden zumindest die freien Enden der Schenkel 3a, 3b nach dem Einlegen des Fugenbandes 7 in die in Fig. 2 gestrichelt gezeichnete Position gebogen. In dieser Position werden sie durch einen oder mehrere, über die Länge des Fugenschatungselementes 1 verteilte Rödeldrähte 9 gehalten, die den noch verbleibenden Abstand zwischen den beiden zusammengebogenen, freien Enden der Schenkel 3a, 3b überbrücken.To prevent the joint tape 7 during the concreting process pushed out of the bracket construction will, i.e. to further secure the position of the joint tape 7, at least the free ends of the Legs 3a, 3b after inserting the joint tape 7 bent into the position shown in dashed lines in FIG. 2. In this position, they are replaced by one or more, over the length of the jointing element 1 distributed solder wires 9 held the remaining one Distance between the two bent, bridge the free ends of the legs 3a, 3b.

    Für einen guten Zusammenhalt der Bestandteile des Fugenschalungselementes wird die für das Bügelteil verwendete Gittermatte derart gebogen, daß die Längsstäbe nach außen weisen. Der Zuschnitt der Gittermatte erfolgt möglichst so, daß einer ihrer Längsstäbe sich etwa in der Mitte der Schenkel 3a und 3b befindet. Die Schalungsteile 2a und 2b werden ebenfalls derart geschnitten, daß einer der Längsstäbe 5 an der den Bügelteil anliegenden Längskante verläuft. Mit Hilfe dieser beiden Längsstäbe können dann die Schalungsteile 2a, 2b sicher und rechtwinklig mit den Schenkel 3a, 3b des Bügelteiles verschweißt werden. Zur zusätzlichen Versteifung können weiterhin die in Figur 1 ersichtlichen Winkelstäbe 8a bzw. 8b verwendet werden, die an der dem Steg 3c des Bügelteiles abgewandten Seite an jeweils einem Schalungsteil 2a und 2b und dem anliegenden freien Schenkel 3a, 3b des Bügelteiles verschweißt sind. Die Anzahl der Winkelstäbe 8a, 8b richtet sich nach der gewünschten Versteifung.For a good cohesion of the components the joint formwork element is for the bracket part used mesh mat bent so that the longitudinal bars point outwards. Cutting the grid mat if possible, one of their longitudinal bars should be is located approximately in the middle of the legs 3a and 3b. The Formwork parts 2a and 2b are also cut in such a way that one of the longitudinal rods 5 on the bracket part adjacent longitudinal edge. With the help of these two Longitudinal bars can then formwork parts 2a, 2b securely and at right angles with the legs 3a, 3b of the bracket part be welded. For additional stiffening can continue to see the angle bars shown in Figure 1 8a and 8b are used, which on the Web 3c of the bracket part facing away from each a formwork part 2a and 2b and the adjacent free legs 3a, 3b of the bracket part are welded. The number of angle bars 8a, 8b depends on the desired stiffening.

    Das erfindungsgemäße Fugenschalungselement kann in gleicher Weise wie bekannte Fugenschalungselemente verwendet werden, dh. zunächst als Teil einer Schalung für ein der Fuge anligendes, erstes Betonteil ausgebildet sein. Ist dieses erste Betonteil erstellt, d.h. der Beton an einer Seite der Schalungsteile 2a, 2b unter Einschluß der halben Schenkellänge der Schenkel 3a, 3b des Bügelteiles und der halben Breite des Fugenbandes 7 vergossen, kann das zweite der der Fuge anliegenden Betonteile vergossen werden.The joint formwork element according to the invention can be used in the same way as known joint formwork elements be used, ie. initially as part of a Formwork for a first concrete part that adjusts to the joint be trained. Is this first concrete part created, i.e. the concrete on one side of the formwork parts 2a, 2b below Inclusion of half the leg length of the legs 3a, 3b of the bracket part and half the width of the joint tape 7 potted, the second of the joints Concrete parts are poured.

    In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispieles können für die Schalungsteile auch andere, handelsübliche Schalungsmaterialien verwendet werden. Die korbartige Bügelkonstruktion kann einen anderen Querschnitt aufweisen bzw. auch aus einzelnen Bügeln bestehen, die einzeln mit den jeweiligen Schalungsteilen verbunden sind. Wichtig ist jedoch, daß die Bügelkonstruktion eine offene Wandung aufweist, damit das Fugenband im Beton eingebettet werden kann. Die Winkelstäbe sind nicht unbedingt erforderlich. Gegegenenfalls können andere, bekannte Versteifungen eingesetzt werden. Anstelle des Rödeldrahtes können Klammern oder dgl. zum Zusammenhalten der zusammengebogenen Schenkel der Bügelkonstruktion verwendet werdenIn a modification of the one described and drawn Embodiment can for the formwork parts also other commercially available formwork materials be used. The basket-like frame construction can have a different cross section or also consist of individual stirrups, individually with the respective Formwork parts are connected. However, it is important that the bracket construction has an open wall so that the joint tape is embedded in the concrete can be. The angle bars are not absolutely necessary. Otherwise, other known ones can Stiffeners are used. Instead of the wire can use brackets or the like to hold together the bent leg of the bracket construction be used
