Abstract

The device (1) consists of a retaining element (2) having triangular recesses (5) into which a crossbar (3) is placed. The upper region (6) above the recess (5) is bent, in a first step, to such an extent that the crossbar (3) is unable to slip out of the recess (5), but can be displaced to-and-fro in the recesses as far as the two covering caps at the ends of the crossbar (3). To lock the crossbar (3) in the retaining element (2) the upper region (6) in the retaining element (2) can be bent by a lever (11) inserted into the hole (7), so that the crossbar is clamped in the recesses (5). The retaining element (2), bevelled to a point (4) at the bottom, is produced from an angle iron and the crossbar is produced from an angle iron or from a reinforcing bar. The device is inexpensive and requires no additional loose elements or tools for use.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Fixierung der Lage von zwei zueinander in Abstand gegenüberstehenden Schalungswänden, bestehend aus einem stabförmigen Halterungselement, welches dazu bestimmt ist, etwa entlang der Mittellinie einer zu errichtenden Mauer in vertikaler Lage in einem Fundament verankert zu werden und einem Querstab, dessen Länge dem Abstand, der einander gegenüberstehenden Schalungswänden entspricht.The present invention relates to a device for fixing the position of two formwork walls facing each other at a distance, consisting of a rod-shaped holding element which is intended to be anchored in a foundation in a vertical position approximately along the center line of a wall to be erected and a crossbar, the length of which corresponds to the distance which corresponds to formwork walls facing one another.

Solche Vorrichtungen sind bekannt aus EP-A 084′017. Das stabförmige Halterungselement besteht dabei aus einem U-förmigen Profilabschnitt. In die beiden parallelen Schenkel des Profilabschnittes ist je ein Durchgangsloch gebohrt, wobei die beiden Löcher miteinander fluchten. Durch die beiden Löcher ist ein frei verschiebbarer Querstab geschoben. Die Fixierung des Querstabes erfolgt mittels einem Fixierstift, der zwischen den Querstab und den U-förmigen Profilstab geschlagen wird. Hierzu ist der Profilstab mit einer in Längsrichtung verlaufenden Kerbe versehen.Such devices are known from EP-A 084'017. The rod-shaped mounting element consists of a U-shaped profile section. A through hole is drilled in each of the two parallel legs of the profile section, the two holes being aligned with one another. A freely displaceable crossbar is pushed through the two holes. The crossbar is fixed by means of a fixing pin, which is struck between the cross bar and the U-shaped profile bar. For this purpose, the profile bar is provided with a notch running in the longitudinal direction.

Von der Funktionsweise her hat sich die bekannte Vorrichtung bestens bewährt. Es besteht jedoch die Gefahr, dass die entsprechenden Fixierstifte verloren gehen oder überhaupt fehlen.The known device has proven itself in terms of functionality. However, there is a risk that the corresponding locating pins will be lost or missing at all.

Eine weitere Vorrichtung obgenannter Art ist in der DE-C 38 23 401 dargestellt. Das stabförmige Halterungselement besteht dabei aus einem Rohrabschnitt oder einem vollen Rundstab. In dieses Halterungselement ist etwa 2-4 cm unterhalb des oberen Endes zu etwa drei Vierteln seines Aussendurchmessers ein Schlitz eingesägt oder eingefräst. Dieser Schlitz dient zur Aufnahme und Fixierung des Querstabes.Another device of the above type is shown in DE-C 38 23 401. The rod-shaped mounting element consists of a tube section or a full round rod. A slot is sawn or milled into this holding element about 2-4 cm below the upper end to about three quarters of its outside diameter. This slot is used to hold and fix the crossbar.

Auch diese Vorrichtung hat sich von der Funktionsweise her bestens bewährt. Die Herstellung des Schlitzes im Rohr oder Rundstab erweist sich jedoch als sehr teure Operation. Zudem muss für das Fixieren des Querstabes ein Werkzeug vorhanden sein, mit dem das obere Ende des Halterungselementes zur Fixierung des Querstabes abgebogen werden kann.This device has also proven its functionality. However, making the slot in the tube or round bar proves to be a very expensive operation. In addition, a tool must be available for fixing the crossbar, with which the upper end of the mounting element can be bent to fix the crossbar.

Vorrichtungen der eingangs genannten Art werden in grosser Menge benötigt und verbleiben in der Mauer. Daher spielt der Preis eine wichtige Rolle.Devices of the type mentioned are required in large quantities and remain in the wall. Therefore, the price plays an important role.

Die vorliegende Erfindung stellt sich nunmehr zur Aufgabe, eine Vorrichtung gemäss dem Oberbegriff des Patentanspruches 1 zu schaffen, die ohne Fixierstifte und ohne spezielles Werkzeug eingebaut wird, und preislich günstiger gefertigt werden kann.The present invention has for its object to provide a device according to the preamble of claim 1, which is installed without fixing pins and without special tools, and can be manufactured cheaper.

Diese Aufgabe löst eine Vorrichtung zur Fixierung der Lage von zwei zueinander in Abstand gegenüberstehenden Schalungswänden mit den Merkmalen des Patentanspruches 1. Weitere erfindungsgemässe Merkmale gehen aus den abhängigen Ansprüchen hervor und deren Vorteile sind in der nachfolgenden Beschreibung erläutert.

This object is achieved by a device for fixing the position of two formwork walls which are at a distance from one another and have the features of claim 1. Further features according to the invention emerge from the dependent claims and their advantages are explained in the following description.
The drawing shows:
  • Figure 1 shows the device in the use position on the building;

  • FIGS. 5a and 5b illustrate the use of the alternatives of the device, again in different stages.
  • Figure 6 shows the device in the use position under construction with an additional simplified auxiliary mounting element.

Während der Erstellung der Bodendeckenplatte B, bzw. eines Fundamentes wird in den noch nicht ausgehärteten Beton die erfindungsgemässe Vorrichtung, die gesamthaft mit 1 bezeichnet ist, eingeschlagen. Die beiden Schalungswände 12 und 13 werden beidseits an die Vorrichtung 1 anliegend errichtet und mittels Spanner 10 aneinander gezogen. Hierauf wird der Frischbeton zwischen den Schalungswänden eingefüllt. Die erfindungsgemässen Distanzierungsvorrichtungen werden vollständig vom Beton verdeckt und gehen verloren.During the creation of the floor slab B, or a foundation, the device according to the invention, which is designated as a whole by 1, is hammered into the not yet hardened concrete. The two formwork walls 12 and 13 are erected on both sides of the device 1 and pulled together by means of tensioner 10. The fresh concrete is then poured in between the formwork walls. The spacing devices according to the invention are completely covered by the concrete and are lost.

Die erfindungsgemässe Vorrichtung 1 besteht aus zwei Grundelementen, dem Halterungselemt 2 und dem Querstab 3. Das Halterungselement 2 ist in der dargestellten Ausführung aus einem Winkeleisen gefertigt. Am unteren Ende sind die Schenkel schräg abgeschnitten. Die so gebildete Spitze 4 erleichtert das Einstossen der Vorrichtung in den Frischbeton. Das für das Halterungselement gewählte Winkeleisen hat vorzugsweise eine Flankenlänge von 20-30 mm. Etwa 5-6 cm unterhalb des oberen Endes des Halterungselementes 2 sind in beide Schenkel 8 dreieckförmige Aussparungen 5 eingestanzt. Diese Aussparungen 5 sind in den Schenkeln 8 fluchtend eingebracht, sodass der Querstab 3 hineingeschoben werden kann. Der Querstab 3 ist aus einem Winkeleisen oder einem strukturierten Armierungseisen gefertigt, und an seinen Enden mit einer Kunststoffkappe versehen.The device 1 according to the invention consists of two basic elements, the mounting element 2 and the crossbar 3. The mounting element 2 is in the embodiment shown made from an angle iron. At the lower end, the legs are cut off at an angle. The tip 4 thus formed facilitates the pushing of the device into the fresh concrete. The angle iron chosen for the mounting element preferably has a flank length of 20-30 mm. About 5-6 cm below the upper end of the holding element 2 8 triangular recesses 5 are punched into both legs. These recesses 5 are made in alignment in the legs 8, so that the crossbar 3 can be pushed in. The crossbar 3 is made of an angle iron or a structured reinforcing iron, and is provided at its ends with a plastic cap.

Der am Halterungselement 2 zwischen Längsseiten der beiden dreieckförmigen Aussparungen 5 vorhandene Steg wird in der Produktion vorgebogen, damit sich das Halterungselement 2 auf der Baustelle am richtigen Ort verformt und die erforderliche Kraft für diese Verformung nicht mehr zu gross ist.The web present on the mounting element 2 between the long sides of the two triangular cutouts 5 is pre-bent in production so that the mounting element 2 deforms at the construction site at the right place and the force required for this deformation is no longer too great.

Eine weitere Möglichkeit die Kraft für die Verformung des oberen Bereiches 6 zu vermindern ergibt sich dadurch, dass der sich auf der Längsseite der dreieckförmigen Aussparung 5 ergebende Steg 9 um ca 5 mm unterbrochen wird. Die verbleibenden Stummel halten den Querstab 3 und der obere Bereich 6 des Halterungselementes 2 lässt sich mit wenig Kraft biegen. Zudem entfällt der Arbeitsgang des Vorbiegens des Steges 9.A further possibility of reducing the force for the deformation of the upper region 6 results from the fact that the web 9 resulting on the long side of the triangular recess 5 is interrupted by approximately 5 mm. The remaining Stub hold the cross bar 3 and the upper portion 6 of the support member 2 can be bent with little force. In addition, the step of pre-bending the web 9 is omitted.

Etwa 1-2 cm vom oberen Ende des Halterungselementes 2 ist ein über den Scheitel sich erstreckendes Loch 7 eingestanzt. Dieses Loch dient auf der Baustelle dazu ein Rundeisen 11 einzustecken und durch dessen Hebelwirkung mit relativ wenig Kraft das Abknicken des oberen Bereiches 3 des Halterungselementes vorzunehmen. Die Dimensionierung des Loches ist so gestaltet, dass auch die Spitze eines Bauhammers oder eines Meisels darin Platz findet.About 1-2 cm from the upper end of the holding element 2, a hole 7 extending over the apex is punched. This hole is used on the construction site to insert a round bar 11 and to bend the upper area 3 of the mounting element with relatively little force due to its leverage. The dimensioning of the hole is designed in such a way that the tip of a building hammer or a chisel also fits into it.

Wie in Figur 1 dargestellt, wird die Vorrichtung etwa in der Mitte der zu erstellenden Wand in den Frischbeton eingesetzt. Der Querstab 3 wird nun so verschoben, dass eine Ende auf die äussere Schalungswand 12 ausgerichtet ist. Nun wird mit einem Rundeisen 11 wie in Figur 3a angedeutet der obere Bereich 6 des Halterungselementes 2 abgeknickt. Die Aussparungen 5 verformen sich bei dieser Knickung derart, dass sich auch der aus Winkeleisen bestehende Querstab verformt und mit dem Halterungselement unverrückbar verbunden ist.As shown in Figure 1, the device is inserted approximately in the middle of the wall to be created in the fresh concrete. The crossbar 3 is now moved so that one end is aligned with the outer formwork wall 12. Now the upper area 6 of the holding element 2 is bent with a round bar 11 as indicated in FIG. 3a. The recesses 5 deform at this kink in such a way that the crossbar, which consists of angle iron, is deformed and is immovably connected to the mounting element.

Wenn die Distanz zwischen den Schalungswänden 12 und 13 den Abstand von 35 cm überschreitet, empfiehlt es sich ein weiteres, vereinfachtes und stabförmiges Hilfshalterungselement 21 einzusetzen um im rauhen Betrieb wie es eine Baustelle darstellt ein Verbiegen des Querstabes 3 zu vermeiden. Wenn ein solches Hilfshalterungselement 21 eingesetzt wird, schlägt man das Halterungselement 2 nicht in der Mitte, sondern in der Nähe der einen Schalungswand 12 oder 13 in den noch nicht ausgehörteten Beton der Bodendeckenplatte. Der längere Teil des Querstabes wird sodann mit dem Hilfshalterungselement gestützt. Das Hilfshalterungselement 21 wird auch in den Beton eingeschlagen, ist aber im Unterschied zum Halterungselement 2 nicht mit dem Querstab 3 verklemmt. Das Hilfshalterungselement 21 ist am einen Ende mit einer vorbereiteten Oeffnung versehen, durch die der Querstab 3 geführt wird. Das Hilfshalterungselement 21 dient nur der Stabilisierung und dem Support des Querstabes.If the distance between the formwork walls 12 and 13 exceeds the distance of 35 cm, it is advisable to use a further, simplified and rod-shaped auxiliary mounting element 21 in order to avoid bending of the crossbar 3 in rough operation, as is a construction site. If such an auxiliary mounting element 21 is used, the mounting element 2 is not hit in the middle, but near one of the formwork walls 12 or 13 in the concrete of the floor slab that has not yet been heard. The longer part of the crossbar is then supported with the auxiliary bracket element. The auxiliary bracket element 21 is also hammered into the concrete, but, unlike the bracket element 2, is not jammed with the crossbar 3. The auxiliary mounting element 21 is provided at one end with a prepared opening through which the crossbar 3 is guided. The auxiliary bracket member 21 is used only to stabilize and support the crossbar.

Wird als Querstab 3 ein aus vollem Material bestehendes Profil verwendet, hat dieses mit Vorteil eine strukturierte Oberfläche, welche die Griffigkeit der Verbindung mit dem Halterungselement 2 erhöht. Es wäre denkbar, dass der Querstab 3 aus einem strukturiertem Armierungsstahl gefertigt ist.If a profile made of solid material is used as the crossbar 3, this advantageously has a structured surface which increases the grip of the connection with the mounting element 2. It would be conceivable for the cross bar 3 to be made of a structured reinforcing steel is made.

Die erfindungsgemässe Vorrichtung 1 ist nicht nur äusserst preisgünstig bezüglich Materialaufwand und Fertigung, sondern bildet auch für die Auslieferung eine Einheit. Zur Arretierung des Querstabes 3 in seiner gewünschten Lage sind keine gesonderten losen Teile erforderlich. Für das Applizieren der Vorrichtung 1 wird lediglich ein Rundeisen 11 als Hebel benötigt, welches in Form von Resten der Armierungsstähle auf einer Baustelle immer vorhanden sind.The device 1 according to the invention is not only extremely inexpensive in terms of material expenditure and production, but also forms a unit for delivery. No separate loose parts are required to lock the crossbar 3 in its desired position. For the application of the device 1, only a round bar 11 is required as a lever, which is always present in the form of remnants of the reinforcing steel on a construction site.

Die dreieckförmige Aussparung 5 kann auch, wie in Figur 4 gezeigt, mit der Grundlinie des Dreiecks vom Scheitel 14 des Halterungselementes 2 entfernt, in die beiden Schenkel 8 eingestanzt werden. Die Knickung erfolgt dann auf die dem Scheitel 14 des Halterungselementes abgewandte Seite und es bestehen zwei Stege 9′, welche an den Flanken 16 entstehen. In der Funktion der Vorrichtung ändert sich dadurch nichts.The triangular recess 5 can also, as shown in FIG. 4, be removed with the base line of the triangle from the apex 14 of the mounting element 2 and punched into the two legs 8. The buckling then takes place on the side facing away from the apex 14 of the mounting element and there are two webs 9 'which are formed on the flanks 16. This does not change the function of the device.

Erfindungswesentlich ist es auch, dass das über der Aussparung 5 im Scheitelbereich angebrachte Loch 7 eine Verformung durch Biegen mittels einem Hebel erlaubt. Sollte der Querstab bei der ersten Klemmung noch nicht vollständig am richtigen Ort sein, lässt sich die Aussparung 5 nochmals leicht aufspreizen. Die Klemmung mittels Biegung garantiert auch, dass das Halterungselement sich in nicht vollständig ausgehärteten Beton nicht nochmals löst. Diese Gefahr bestand bei allen Elementen, bei denen durch Schlagwirkung, beispielsweise mit einem Hammer, die Verbindung zwischen Halterungselement und Querstab sichergestellt wurde.It is also essential to the invention that the hole 7 made above the recess 5 in the apex region allows deformation by bending by means of a lever. If the crossbar is not completely in the right place when it is clamped for the first time, the recess 5 can be opened spread again slightly. Clamping by means of bending also guarantees that the support element does not come loose again in not fully hardened concrete. This risk existed for all elements in which the connection between the mounting element and the crossbar was ensured by impact, for example with a hammer.
