Definitions
- 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.
- 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 cross bar is fixed by means of a fixing pin which is struck between the cross bar and the U-shaped profile bar. This is the profile bar is provided with a notch running in the longitudinal direction.
- 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.
- the rod-shaped mounting element consists of a tube section or a full round rod.
- a slot is sawn or milled into this mounting 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.
- 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.
- a further variant is shown in CH-A-664'186, in which a fixing device is described according to the method.
- This also consists of a rod-shaped fixing element in the Form of a U-profile, which is provided at its upper leg ends with two recesses, in which a crossbar with grooves can be inserted in a form-fitting manner.
- a tab protruding from the ends of the legs formed from the base of the profile can be bent over an inserted cross bar.
- This solution is also rather expensive because of the special crossbar. It is also doubtful that the bracket withstands the forces that occur when the formwork walls are set.
- DE-A-38 11 809 shows a device that comes close to the device already cited according to EP-A-0 084 017, here an L-profile is used instead of a U-profile, the legs of which have recesses that are aligned with one another a cross bar is slidably held and which in turn is held and secured with a round wedge as a fixing pin.
- the present invention has for its object to provide a device according to the preamble of claim 1, which is installed without additional components, such as fixing pins and without special tools, and can be manufactured at a lower price.
- 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.
- the device 1 consists of two basic elements, the bracket element 2 and the angle iron 3 as a crossbar.
- the mounting element 2 is made in the illustrated embodiment 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.
- triangular recesses 5 are punched into both legs 8, so that the holding element 2 can bend slightly at this point. These recesses 5 are made in alignment in the legs 8, so that the angle iron 3 can be pushed in.
- the crossbar is made of an angle iron 3 or a structured reinforcing iron and is provided with a plastic cap (15) at its ends.
- 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 is deformed at the construction site at the right place, at the cutouts 5, and the force required for this deformation is no longer too great.
- a further possibility for 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 stubs hold the angle iron 3 and the upper region 6 of the mounting element 2 can be bent with little force. In addition, the step of pre-bending the web 9 is omitted.
- a hole 7 extending over the apex is punched. This hole is used on the construction site for a round bar 11 to insert and by its leverage with relatively little force to bend the upper portion 3 of the support member.
- the dimensioning of the hole is designed in such a way that the tip of a construction hammer or a chisel also fits into it.
- the device is inserted approximately in the middle of the wall to be created in the fresh concrete.
- the angle iron 3 is now moved so that one end is aligned with the outer formwork wall 12.
- a round bar 11 as indicated in FIG. 3a, the upper area 6 of the holding element 2 is bent.
- 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.
- auxiliary mounting element 21 is used in order to avoid bending the angle iron 3 in rough operation, as it 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 not yet hardened concrete of the floor slab. The longer part of the angle iron is then supported with the auxiliary bracket element. The auxiliary bracket element 21 is also hammered into the concrete, but in contrast to the bracket element 2 is not jammed with the angle iron 3.
- the auxiliary mounting element 21 is provided at one end with a prepared opening through which the angle iron 3 is guided.
- the auxiliary bracket member 21 is used only to stabilize and support the crossbar. If a profile made of solid material is used as the angle iron 3, this advantageously has a structured surface which increases the grip of the connection with the mounting element 2. It would be conceivable that the angle iron 3 is made of a structured reinforcing steel.
- 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 angle iron 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 steels on a construction site.
- 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 kinking then takes place on the side facing away from the apex 14 of the holding element and there are two webs 9 'which are formed on the flanks 16. This does not change the function of the device.
- 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 first clamped, the cutout 5 can be easily widened again. 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.

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 den 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-0 084 017, beziehungsweise CH-A-651'882. 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-0 084 017 or CH-A-651'882. 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 cross bar is fixed by means of a fixing pin which is struck between the cross bar and the U-shaped profile bar. This is 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 2-4cm 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 mounting 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.
Eine weitere Variante zeigt die CH-A-664'186, in der eine Fixiervorrichtung verfahrensgemäss beschrieben wird. Dieser besteht auch aus einem stabförmigen Fixierelement in der Form eines U-Profiles, welches an seinen oberen Schenkelenden mit zwei Ausnehmungen versehen ist, in dem ein Querstab mit Rillen formschlüssig einlegbar ist. Ein die Schenkelenden überragende Lasche geformt aus dem Profilgrund lässt sich über einen eingelegten Querstab umbiegen. Auch diese Lösung ist wegen des speziellen Querstabes eher kostspielig. Auch ist es zweifelhaft, dass die Lasche, die beim Setzen der Schalungwände auftretenden Kräfte, Stand hält.A further variant is shown in CH-A-664'186, in which a fixing device is described according to the method. This also consists of a rod-shaped fixing element in the Form of a U-profile, which is provided at its upper leg ends with two recesses, in which a crossbar with grooves can be inserted in a form-fitting manner. A tab protruding from the ends of the legs formed from the base of the profile can be bent over an inserted cross bar. This solution is also rather expensive because of the special crossbar. It is also doubtful that the bracket withstands the forces that occur when the formwork walls are set.
Eine, der bereits zitierten Vorrichtung gemäss der EP-A-0 084 017, nahe kommende Vorrichtung zeigt die DE-A-38 11 809, hier wird statt eines U-Profiles ein L-Profil verwendet, deren Schenkel miteinander fluchtende Ausnehmungen aufweist, durch die ein Querstab verschiebbar gehalten ist und der wiederum mit einem Rundkeil als Fixierstift gehalten und gesichert wird.DE-A-38 11 809 shows a device that comes close to the device already cited according to EP-A-0 084 017, here an L-profile is used instead of a U-profile, the legs of which have recesses that are aligned with one another a cross bar is slidably held and which in turn is held and secured with a round wedge as a fixing pin.
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 zusätzliche Bauteile, wie 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 additional components, such as fixing pins and without special tools, and can be manufactured at a lower price.
Vorteile der Erfindung sind einerseits, dass nur zwei Bauteile nötig sind, zur Erfüllung der Funktion und diese Bauteile aus gleichartigem Profil hergestellt sind. Dadurch wird nicht nur die Herstellung, sondern auch die Montage und Handhabung sehr einfach.The advantages of the invention are, on the one hand, that only two components are required to perform the function and that these components are made from the same profile. This makes not only the manufacture but also the assembly and handling very easy.
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 spaced apart from one another with 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.

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
Die erfindungsgemässe Vorrichtung 1 besteht aus zwei Grundelementen, dem Halterungselemt 2 und dem Winkeleisen 3 als Querstab. 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.The device 1 according to the invention consists of two basic elements, the
Etwa 5-6 cm unterhalb des oberen Endes des Halterungselementes 2 sind in beide Schenkel 8 dreieckförmige Aussparungen 5 eingestanzt, so dass sich das Halterungselement 2 an dieser Stelle leicht knicken lässt. Diese Aussparungen 5 sind in den Schenkeln 8 fluchtend eingebracht, so dass das Winkeleisen 3 hineingeschoben werden kann. Der Querstab ist aus einem Winkeleisen 3 oder einem strukturierten Armierungseisen gefertigt, und an seinen Enden mit einer Kunststoffkappe (15) versehen.About 5-6 cm below the upper end of the
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, an den Aussparungen 5, verformt und die erforderliche Kraft für diese Verformung nicht mehr zu gross ist.The web present on the
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 5mm unterbrochen wird. Die verbleibenden Stummel halten das Winkeleisen 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 for reducing the force for the deformation of the
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
Wie in Figur 1 dargestellt, wird die Vorrichtung etwa in der Mitte der zu erstellenden Wand in den Frischbeton eingesetzt. Das Winkeleisen 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
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 Winkeleisens 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 ausgehärteten Beton der Bodendeckenplatte. Der längere Teil des Winkeleisens 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 Winkeleisen 3 verklemmt. Das Hilfshalterungselement 21 ist am einen Ende mit einer vorbereiteten Oeffnung versehen, durch die das Winkeleisen 3 geführt wird. Das Hilfshalterungselement 21 dient nur der Stabilisierung und dem Support des Querstabes.
Wird als Winkeleisen 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 das Winkeleisen 3 aus einem strukturiertem Armierungsstahl gefertigt ist.If the distance between the
If a profile made of solid material is used as the
Die erfindungsgemässe Vorrichtung 1 ist nicht nur äusserst preisgünstig bezüglich Materialaufwand und Fertigung, sondern bildet auch für die Auslieferung eine Einheit. Zur Arretierung des Winkeleisens 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
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
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
