Description

Die Erfindung betrifft eine Stützvorrichtung für den Baubereich, insbesondere zum Stützen einer Unterzugschalung, mit einem länglichen, horizontalen Querträger und zumindest zwei senkrecht zum Querträger angeordneten Stützkörpern, wobei die Stützkörper höhenverstellbar sind.The invention relates to a support device for the construction sector, in particular for supporting a joist formwork, with an elongate, horizontal crossbeam and at least two support bodies arranged perpendicularly to the crossbeam, the support bodies being height-adjustable.

Eine derartige Stützvorrichtung ist aus der DE 1 684 236 A bekannt. Dabei liegen vertikale und horizontale Schalungselemente einer Unterzugschalung auf dem Querträger auf, und werden durch die Stützelemente seitlich gestützt. Nachteilig an derartigen Stützvorrichtungen ist, dass sie vergleichsweise sperrig und kompliziert in der Handhabung sind. Beispielsweise muss eine derartige Stützvorrichtung durch zumindest zwei Schraubstützen am Boden abgestützt werden, was viel Platz auf der Baustelle einnimmt. Zudem sind die Einsatzmöglichkeiten dieser Stützvorrichtung aufgrund ihrer vergleichsweise sperrigen Geometrie auf die Abstützung von Unterzugschalungen limitiert.Such a support device is from DE 1 684 236 A known. Vertical and horizontal formwork elements of a joist formwork lie on the crossbeam and are laterally supported by the support elements. A disadvantage of such support devices is that they are comparatively bulky and complicated to handle. For example, such a support device must be supported on the ground by at least two screw supports, which takes up a lot of space on the construction site. In addition, the possible uses of this support device are limited to the support of beam formwork due to its comparatively bulky geometry.

KR 100926750 B1 offenbart ein Schalungssystem, bei dem zwei durch mehrere Querträger verbundene Längsträger eine U-förmige Schalung tragen. Auf den Längsträgern sind Längsbalken befestigt, auf denen wiederum höhenverstellbare Stützkörper aufbauen. Die DE 1049076 B zeigt eine hängende Schalungszarge, die an endseitigen Auflagerpratzen durch von Baustützen getragene Querbalken abgestützt wird. KR 100926750 B1 discloses a formwork system in which two longitudinal members connected by a plurality of cross members carry a U-shaped formwork. Longitudinal beams are fastened to the longitudinal beams, on which in turn height-adjustable support bodies are built. The DE 1049076 B shows a hanging formwork frame, which is supported on end-side bearing claws by crossbeams carried by props.

Daher liegt der Erfindung die Aufgabe zugrunde, eine Stützvorrichtung der eingangs genannten Art bereitzustellen, die die vorgenannten Nachteile vermeidet.The invention is therefore based on the object of providing a support device of the type mentioned at the outset which avoids the aforementioned disadvantages.

Diese Aufgabe wird dadurch gelöst, dass der Querträger längenvariabel ausgebildet ist. Dadurch kann die gesamte Breite der Stützvorrichtung durch eine Anpassung der Länge des Querträgers optimal an einen zu schalenden Unterzug angepasst werden. Die erfindungsgemäße Stützvorrichtung ist dadurch kompakter und leichter in der Handhabung.This object is achieved in that the cross member is designed to be variable in length. As a result, the entire width of the support device can be optimally adapted to a beam to be formed by adjusting the length of the crossbeam. The support device according to the invention is therefore more compact and easier to handle.

Mit Vorteil sind die Stützkörper an den Enden des Querträgers angeordnet, wodurch die Stützvorrichtung noch kompakter ist, da der Querträger bezogen auf die Stützkörper möglichst wenig übersteht.The support bodies are advantageously arranged at the ends of the cross member, as a result of which the support device is even more compact, since the cross member protrudes as little as possible relative to the support body.

Die erfindungsgemäße Stützvorrichtung lässt sich mit Hilfe lediglich einer Schraubstütze oder einer anderen Baustütze abstützen und nimmt somit weniger Platz auf der Baustelle ein.The support device according to the invention can be supported using only one screw support or another construction support and thus takes up less space on the construction site.

Insbesondere ist der Querträger teleskopartig aus- bzw. einfahrbar, wodurch eine stabile Längenverstellung möglich ist. Dazu umfasst der Querträger zumindest zwei koaxial angeordnete Querträgersegmente. Vorzugsweise ist zur stufenlosen Längenverstellung des Querträgers eine innerhalb der Querträgersegmente angeordnete Gewindestange vorgesehen, die mit zumindest einer an einem der Querträgersegmente festgelegten Verschiebemutter zusammenwirkt. Alternativ können die Querträgersegmente über einen Kraftschluss, beispielsweise durch eine seitlich angreifende Stellschraube oder eine Schelle, relativ zueinander festgelegt werden, wobei eine Längenverstellung per Hand erfolgt. Ferner kann auch eine gestufte Festlegung mithilfe von Sicherungsbolzen vorgesehen sein. Insbesondere sind die Querträgersegmente lösbar miteinander verbunden.In particular, the crossbeam can be extended or retracted telescopically, as a result of which a stable length adjustment is possible. For this purpose, the cross member comprises at least two coaxially arranged cross member segments. A threaded rod which is arranged inside the cross-beam segments and interacts with at least one sliding nut fixed on one of the cross-beam segments is preferably provided for the stepless length adjustment of the cross-beam. Alternatively, they can Cross member segments are fixed relative to one another by means of a frictional connection, for example by means of a laterally acting adjusting screw or a clamp, the length being adjusted by hand. Furthermore, a stepped fixing with the help of safety bolts can also be provided. In particular, the cross member segments are detachably connected to one another.

In einer weiteren Ausgestaltung der Erfindung ist an zumindest einem der Stützkörper ein Seitenträger angeordnet, der sich in einer senkrecht zu einer Längsrichtung bzw. Längsmittelachse des Querträgers und senkrecht zu einer Längsrichtung bzw. Längsmittelachse des Stützkörpers verlaufenden Richtung erstreckt. Der Seitenträger bildet dabei eine vertikale Abstützfläche aus, die in einer Ebene senkrecht zur Längsrichtung bzw. Längsmittelachse des Querträgers verläuft. Somit erfährt ein vertikales Schalungselement, auch ohne die Verwendung von Kanthölzern, eine verbesserte seitliche Stabilisierung. Insgesamt kann daher zum Abstützen einer Schalung eine geringere Anzahl an Stützvorrichtungen eingesetzt werden, was den für den Einsatz der Stützvorrichtung notwendigen Arbeitsaufwand und Platzbedarf senkt. Dabei sind Schalungselemente nicht Teil der Erfindung.In a further embodiment of the invention, a side support is arranged on at least one of the support bodies, which extends in a direction perpendicular to a longitudinal direction or longitudinal center axis of the cross member and perpendicular to a longitudinal direction or longitudinal center axis of the support body. The side member forms a vertical support surface that runs in a plane perpendicular to the longitudinal direction or longitudinal center axis of the cross member. In this way, a vertical formwork element experiences improved lateral stabilization, even without the use of squared timber. Overall, therefore, a smaller number of support devices can be used to support a formwork, which reduces the amount of work and space required for using the support device. In this case, formwork elements are not part of the invention.

Vorzugsweise beträgt die Länge des Seitenträgers zumindest 40 cm, bevorzugt zumindest 60 cm. Insbesondere weist die vertikale Abstützfläche eine Länge von zumindest 40 cm, bevorzugt zumindest 60 cm, und eine Breite von zumindest 2 cm, bevorzugt zumindest 4 cm, auf. Mit Vorteil beträgt die Fläche der vertikalen Abstützfläche zumindest 80 cm2, bevorzugt zumindest 240 cm2. Bei diesen Geometrien ist eine besonders gute Abstützung der Schalungselemente gegeben.The length of the side support is preferably at least 40 cm, preferably at least 60 cm. In particular, the vertical support surface has a length of at least 40 cm, preferably at least 60 cm, and a width of at least 2 cm, preferably at least 4 cm. The area of the vertical support surface is advantageously at least 80 cm 2 , preferably at least 240 cm 2 . These geometries provide particularly good support for the formwork elements.

Seitenträger und Stützkörper können dabei einteilig ausgebildet sein. Vorzugsweise ist der Seitenträger an einem Ende des Stützkörpers festgelegt.Side support and support body can be designed in one piece. Preferably, the side support is fixed to one end of the support body.

Mit Vorteil umfasst der Seitenträger eine L-Profilschiene, eine T-Profilschiene, eine U-Profilschiene und/oder ein Vierkantrohr, welche(s) die vertikale Abstützfläche ausbildet. Dies gewährleistet die nötige Steifheit des Seitenträgers, so dass dieser seitliche Kräfte optimal aufnehmen kann.The side support advantageously comprises an L profile rail, a T profile rail, a U profile rail and/or a square tube, which forms the vertical support surface. This ensures the necessary rigidity of the side carrier so that it can optimally absorb lateral forces.

In einer weiteren Ausgestaltung der Erfindung bildet der Seitenträger eine horizontale Abstützfläche aus, die in einer Ebene parallel zur Längsrichtung bzw. Längsmittelachse des Querträgers verläuft. Dadurch können die Seitenträger zusätzlich zur Abstützung von unten eingesetzt werden. Somit kann die Stützvorrichtung beispielsweise auch zur Abstützung eines Jalousiekastens ohne Zuhilfenahme von Kanthölzern verwendet werden. Insbesondere weist die horizontale Abstützfläche eine Länge von zumindest 40 cm, bevorzugt zumindest 60 cm, und eine Breite von zumindest 2 cm, bevorzugt zumindest 4 cm, auf. Vorzugsweise beträgt die Fläche der horizontalen Abstützfläche zumindest 80 cm2, bevorzugt zumindest 240 cm2. Bei diesen Geometrien ist eine besonders gute Abstützung, beispielsweise eines handelsüblichen Jalousiekastens, gewährleistet.In a further embodiment of the invention, the side member forms a horizontal support surface which runs in a plane parallel to the longitudinal direction or longitudinal center axis of the cross member. This means that the side supports can also be used for support from below. Thus, the support device can also be used, for example, to support a blind box without the aid of squared timber. In particular, the horizontal support surface has a length of at least 40 cm, preferably at least 60 cm, and a width of at least 2 cm, preferably at least 4 cm. The area of the horizontal support surface is preferably at least 80 cm 2 , preferably at least 240 cm 2 . With these geometries, a particularly good support, for example a commercially available shutter box, is guaranteed.

In einer weiteren bevorzugten Ausgestaltung der Erfindung umfassen die Seitenträger Vierkantrohre, wobei die vertikale Abstützfläche sowie die horizontale Abstützfläche von zwei Seiten des Vierkantrohrs ausgebildet werden. Alternativ kann zumindest ein Seitenträger von einer U- oder L-Profilschiene ausgebildet werden, wobei die vertikale und die horizontale Abstützfläche von zwei Seiten der U-Profilschiene oder den beiden Schenkeln der L-Profilschiene ausgebildet werden. Dies gewährleistet die notwendige Steifheit der Seitenträger, die sich sonst bei der Aufnahme der seitlichen Kräfte eines Schalungselements durchbiegen würden.In a further preferred embodiment of the invention, the side supports comprise square tubes, with the vertical support surface and the horizontal support surface be formed from two sides of the square tube. Alternatively, at least one side support can be formed by a U or L profile rail, with the vertical and horizontal support surfaces being formed by two sides of the U profile rail or the two legs of the L profile rail. This ensures the necessary rigidity of the side beams, which would otherwise sag when absorbing the lateral forces of a formwork element.

Erfindungsgemäß sind die Stützkörper höhenverstellbar im und/oder am Querträger geführt. Dazu sind rohrförmige, die Stützkörper entlang ihres Umfangs umschließende Führungselemente am Querträger angeordnet. Vorzugsweise ist die Innenkontur an die Außenkontur des Umfangs der Stützkörper oder Teilen des Stützkörpers angepasst, so dass die Stützkörper formschlüssig in den Führungselementen geführt werden. Dies stabilisiert die Stützkörper gegen seitlich wirkende Kräfte, ohne dass zusätzliche Stützstreben notwendig sind. Hierbei umfasst der Begriff "rohrförmig" auch nicht runde Rohrformen (bspw. Vierkantrohre).According to the invention, the support bodies are guided in and/or on the cross member in a height-adjustable manner. For this purpose, tubular guide elements enclosing the support bodies along their circumference are arranged on the cross member. The inner contour is preferably adapted to the outer contour of the circumference of the support body or parts of the support body, so that the support bodies are guided in the guide elements in a form-fitting manner. This stabilizes the supporting body against laterally acting forces without the need for additional support struts. Here, the term "tubular" also includes non-round tube shapes (e.g. square tubes).

Vorzugsweise schließen die oberen Kanten der Führungselemente mit einer oberen Stützfläche des Querträgers oder des Querträgersegments ab, so dass die Stützkörper größtenteils oder vollständig unter die obere Stützfläche abgesenkt werden können, so dass der daran angeordnete Seitenträger auf der oberen Stützfläche des Querträgers oder des Querträgersegments aufliegt. Dadurch kann im Fall, dass zwei Seitenträger zu Abstützung von unten verwendet werden, beispielsweise beim Abstützen eines Jalousiekastens, der Querträger möglichst nah an zumindest einem der Seitenträger positioniert werden. Eine solche Konfiguration der Stützvorrichtung ist besonders stabil. Zudem ist es durch die größere Höhenvariabilität möglich, auch relativ kleine Unterzüge zu schalen.The upper edges of the guide elements preferably end with an upper support surface of the cross member or the cross member segment, so that the support bodies can be lowered mostly or completely below the upper support surface, so that the side support arranged thereon rests on the upper support surface of the cross member or the cross member segment. In this way, if two side supports are used for support from below, for example when supporting a blind box, the cross support can be positioned as close as possible to at least one of the side supports. Such a configuration of the support device is particularly stable. In addition, due to the greater height variability, it is also possible to form relatively small beams.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Stützkörper ggf. samt Seitenträger aus dem Querträger bzw. aus den Führungselementen herausnehmbar. Dies bietet eine weitere Einsatzmöglichkeit der Stützvorrichtung bei der Abstützung von Randschalungen. Die Stützvorrichtung kann in einer Konfiguration mit nur einem Stützkörper samt Seitenträger mit der obersten Stützfläche des Querträgers, welche von der oberen Stützfläche des äußeren Querträgersegments gebildet wird, eine Decke stützen, während der Stützkörper samt Seitenträger eine Randschalung eines oberhalb der Decke zu gießenden Bodenbelags stützt.In a further advantageous embodiment of the invention, the support bodies can be removed, if necessary together with the side supports, from the cross member or from the guide elements. This offers another possible use of the support device when supporting edge formwork. In a configuration with only one support body and side beam, the support device can support a ceiling with the uppermost support surface of the cross beam, which is formed by the upper support surface of the outer cross beam segment, while the support body and side beam support an edge formwork of a floor covering to be cast above the ceiling.

Mit Vorteil ist der Seitenträger mit Öffnungen versehen, durch die ein an der vertikalen und/oder der horizontalen Abstützfläche anliegendes Schalungselement mittels Schrauben oder anderen Verbindungsmitteln am Seitenträger festgelegt werden kann. Dies erleichtert die schnelle Herstellung einer stabilen Schalung.The side support is advantageously provided with openings through which a formwork element lying against the vertical and/or the horizontal support surface can be fixed to the side support by means of screws or other connecting means. This facilitates the quick production of a stable formwork.

In einer weiteren Ausgestaltung der Erfindung sind an jedem Seitenträger zwei parallel verlaufende Stützkörper festgelegt. Insbesondere sind die beiden an einem Seitenträger angeordneten Stützkörper derart angeordnet, dass ihre Längsmittelachsen in einer Ebene senkrecht zur Längsmittelachse des Querträgers verlaufen.In a further embodiment of the invention, two parallel support bodies are fixed to each side member. In particular, the two support bodies arranged on a side member are arranged in such a way that their longitudinal center axes run in a plane perpendicular to the longitudinal center axis of the cross member.

Dies führt zu einer weiteren Erhöhung der Stabilität, ohne die Gesamtbreite der Stützvorrichtung zu vergrößern.This leads to a further increase in stability without increasing the overall width of the support device.

Vorzugsweise sind die Stützkörper an den diese aufnehmenden Führungselementen durch herausnehmbare Verriegelungsbolzen festgelegt, wobei Längsmittelachsen der Verriegelungsbolzen parallel zu den Seitenträgern verlaufen. Dadurch können im Fall, dass zwei Stützkörper an einem Seitenträger angeordnet sind, beide Stützkörper durch einen gemeinsamen Verriegelungsbolzen festgelegt werden. Dazu weisen die Stützkörper und die diese aufnehmenden Führungselemente entsprechende Bohrungen auf.The support bodies are preferably fixed to the guide elements receiving them by removable locking bolts, the longitudinal center axes of the locking bolts running parallel to the side supports. As a result, in the event that two supporting bodies are arranged on a side support, both supporting bodies can be fixed by a common locking bolt. For this purpose, the support bodies and the guide elements receiving them have corresponding bores.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Querträger ein Adapterelement zum Anschluss externer, nicht zur Erfindung gehörender Schraubstützen oder anderer Baustützen auf. Die Stützvorrichtung kann somit kraft- und/oder formschlüssig mit einer Baustütze verbunden werden. Insbesondere weist das Adapterelement dafür ein Gewinde zur Herstellung einer Schraubverbindung auf. Dies führt zu einer leicht herstellbaren und besonders stabilen Verbindung zwischen Stützvorrichtung und Baustütze. Schraubstützen oder andere Baustützen sind dabei nicht Teil der Erfindung.In a further advantageous embodiment of the invention, the cross member has an adapter element for connecting external screw supports or other building supports that do not belong to the invention. The support device can thus be connected to a prop in a non-positive and/or positive manner. In particular, the adapter element has a thread for producing a screw connection. This leads to an easily manufacturable and particularly stable connection between the support device and the prop. Screw supports or other building supports are not part of the invention.

In einer weiteren Ausgestaltung der Erfindung weist zumindest einer der Seitenträger ein Aufnahmeelement zur Aufnahme einer Absturzsicherung oder eines Teils davon auf. Das Aufnahmeelement ist vorzugsweise in Form eines Rohrs auf der der vertikalen Abstützfläche abgewandten Seite des Seitenträgers angeordnet. Dadurch sind weniger oder keine weiteren Stützhilfen für eine Absturzsicherung nötig, was zu mehr Platz auf der Baustelle führt.In a further embodiment of the invention, at least one of the side supports has a receiving element for receiving a fall protection or a part thereof. The receiving element is preferably arranged in the form of a tube on the side of the side support facing away from the vertical support surface. As a result, fewer or no further support aids are required for fall protection, which leads to more space on the construction site.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung umfasst die Stützvorrichtung einen Laser zur Ausrichtung der Stützvorrichtung und/oder der Schalungselemente. Vorzugsweise stellt der Laser einen parallel zur vertikalen Abstützfläche sowie parallel zur horizontalen Abstützfläche verlaufenden Laserstrahl bereit. Dadurch kann bei waagerechter Ausrichtung der Seitenträger anhand des auf eine vertikal verlaufende Wand projizierten Lasers die Höhenlage der Stützvorrichtung kontrolliert werden.In a further advantageous embodiment of the invention, the support device includes a laser for aligning the support device and/or the formwork elements. The laser preferably provides a laser beam running parallel to the vertical support surface and parallel to the horizontal support surface. As a result, when the side supports are aligned horizontally, the height of the supporting device can be checked using the laser projected onto a vertically running wall.

Vorzugsweise ist der Laser an oder in einem Seitenträger angeordnet. Beispielsweise kann somit eine Ausbeulung eines vertikalen Schalungselements überprüft werden, indem über die Länge des Schalungselements der Abstand zwischen Schalungselement und Laserstrahl gemessen wird. Ferner können auch zwei Stützvorrichtungen zueinander ausgerichtet werden, indem beispielsweise eine festgelegte Stützvorrichtung einen Laserstrahl bereitstellt und eine weitere Stützvorrichtung daran ausgerichtet wird.The laser is preferably arranged on or in a side support. For example, a bulging of a vertical formwork element can thus be checked by measuring the distance between the formwork element and the laser beam over the length of the formwork element. Furthermore, two supporting devices can also be aligned with one another, for example by a fixed supporting device providing a laser beam and a further supporting device being aligned with it.

Insbesondere weisen als Vierkantrohr ausgebildete Seitenträger beidseitig Endkappen auf, wobei der Laser in einer der Endkappen angeordnet ist.In particular, side supports designed as a square tube have end caps on both sides, with the laser being arranged in one of the end caps.

In einer weiteren bevorzugten Ausgestaltung der Erfindung weist der Seitenträger ein Lagerelement auf, das insbesondere in Form einer L-Profilschiene zur Aufnahme eines von oben einsetzbaren Schalungselements ausgebildet ist und das Schalungsbrett von unten und seitlich abstützt. Lagerelement und Seitenträger können dabei auch einteilig ausgebildet sein.In a further preferred embodiment of the invention, the side support has a bearing element which is designed in particular in the form of an L profile rail for receiving a formwork element that can be inserted from above and supports the formwork board from below and laterally. Bearing element and side support can also be designed in one piece.

Die erfindungsgemäße Stützvorrichtung ist somit ein multifunktionales Bauhilfsmittel bzw. Werkzeug für den Bau.The support device according to the invention is thus a multifunctional construction aid or tool for construction.

Die nachfolgend erläuterten Merkmale der erfindungsgemäßen Ausführungsbeispiele können auch gemäß den Ansprüchen in anderen Kombinationen als dargestellt oder beschrieben Gegenstand der Erfindung sein. Nachfolgend werden gleichwirkende Elemente der Erfindung mit einer einheitlichen Bezugsziffer versehen, sofern dies sinnvoll ist.The features of the exemplary embodiments according to the invention explained below can also be the subject matter of the invention according to the claims in combinations other than those shown or described.

Fig. 1 bis 7 zeigen verschiedene Ausführungsformen einer erfindungsgemäßen Stützvorrichtung 2 für den Baubereich mit einem länglichen, horizontalen Querträger 4 sowie vier paarweise endseitig am und senkrecht zum Querträger 4 angeordneten, höhenverstellbaren, länglichen Stützkörpern 6. Der Querträger 4 ist teleskopartig aus- bzw. einfahrbar und dadurch längenvariabel. Der Querträger 4 umfasst zwei koaxial angeordnete Querträgersegmente 4a, 4b in Form von Vierkantrohren. Die einzelnen Querträgersegmente 4a, 4b sind somit stabil gegen eine Torsion um eine Längsmittelachse A des Querträgers 4 ausgebildet. Eine koaxial zu den Querträgersegmenten 4a, 4b angeordnete Gewindestange 8 dient der stufenlosen Längenverstellung des Querträgers 4. An je einem Paar von Stützkörpern 6 ist ein Seitenträger 10, 10', 10" angeordnet. Dieser erstreckt sich in einer senkrecht zur Längsmittelachse A des Querträgers 4 und senkrecht zu einer Längsmittelachse B der Stützkörper 6 verlaufenden Richtung. Die Seitenträger 10, 10', 10" bilden eine vertikale Abstützfläche 12 aus, die in einer Ebene senkrecht zur Längsmittelachse A des Querträgers 4 verläuft. Wie aus Fig. 7 deutlich wird, erfährt ein vertikales Schalungselement 30 eine verbesserte seitliche Stabilisierung, die ein Verkippen K des Schalungselements 30 um eine Vertikalachse V verhindert. Schalungselemente sind dabei nicht Teil der Erfindung. Figures 1 to 7 show various embodiments of a support device 2 according to the invention for the construction sector with an elongate, horizontal crossbeam 4 and four pairs of height-adjustable, elongate support bodies 6 arranged at the ends and perpendicular to the crossbeam 4. The crossbeam 4 can be extended or retracted telescopically and is therefore variable in length. The cross member 4 comprises two coaxially arranged cross member segments 4a, 4b in the form of square tubes. The individual cross member segments 4a, 4b are thus designed to be stable against torsion about a longitudinal central axis A of the cross member 4. A threaded rod 8 arranged coaxially to the cross member segments 4a, 4b is used for continuous length adjustment of the cross member 4. A side member 10, 10', 10" is arranged on each pair of support bodies 6. This extends in a direction perpendicular to the longitudinal center axis A of the cross member 4 and perpendicular to a longitudinal center axis B of the support body 6. The side supports 10, 10', 10" form a vertical support surface 12, which is in a plane perpendicular to the longitudinal center axis A of the Cross member 4 runs. How out 7 becomes clear, a vertical formwork element 30 experiences improved lateral stabilization, which prevents tilting K of the formwork element 30 about a vertical axis V. Formwork elements are not part of the invention.

In den in Fig. 1 bis 4 und Fig. 7 gezeigten Ausführungsbeispielen bilden die Seitenträger 10, 10' zudem eine horizontale Abstützfläche 14 aus, die in einer Ebene parallel zur Längsmittelachse A des Querträgers 4 verläuft.in the in Figures 1 to 4 and 7 In the exemplary embodiments shown, the side supports 10 , 10 ′ also form a horizontal support surface 14 which runs in a plane parallel to the longitudinal central axis A of the cross member 4 .

In den Fig. 1, 2 und 7 sind beide Seitenträger 10 als Vierkantrohre ausgebildet, wobei die vertikale Abstützfläche 12 sowie die horizontale Abstützfläche 14 von zwei über Eck gelegenen Seiten des Vierkantrohrs ausgebildet werden. Die Ausführungsformen gemäß den Fig. 3 bis 6 weisen jeweils einen Seitenträger 10 in Form eines Vierkantrohrs auf. In den Fig. 3 und 4 ist ein Seitenträger 10' in Form einer L-Profilschiene gezeigt, wobei die vertikale Abstützfläche 12 und die horizontale Abstützfläche 14 von den beiden Schenkeln der L-Profilschiene ausgebildet werden. Derart ausgebildete Seitenträger 10, 10' weisen die notwendige Steifigkeit auf, um genügend Widerstand gegenüber Belastungen von oben oder von der Seite aufzubringen.In the 1 , 2 and 7 Both side supports 10 are designed as square tubes, with the vertical support surface 12 and the horizontal support surface 14 being formed from two sides of the square tube located across a corner. The embodiments according to Figures 3 to 6 each have a side support 10 in the form of a square tube. In the 3 and 4 a side support 10' is shown in the form of an L profile rail, the vertical support surface 12 and the horizontal support surface 14 being formed by the two legs of the L profile rail. Side supports 10, 10' designed in this way have the necessary rigidity in order to provide sufficient resistance to loads from above or from the side.

Fig. 1 bis 7 zeigen vier paarweise endseitig am Querträger 4 angeordnete Führungselemente 16, in denen die Stützkörper 6 höhenverstellbar geführt sind. Dabei sind jeweils zwei Führungselemente 16 an je einem Querträgersegment 4a, 4b angeordnet. Wie in den Fig. 2, 4 und 6 gezeigt ist, schließen die oberen Kanten der Führungselemente 16 mit einer oberen Stützfläche 18a, 18b jenes Querträgersegments 4a, 4b ab, an dem sie angeordnet sind. In dem Ausführungsbeispiel gemäß Figures 1 to 7 show four guide elements 16 arranged in pairs at the ends of the crossbeam 4, in which the support bodies 6 are guided in a height-adjustable manner. In this case, two guide elements 16 are each arranged on a cross member segment 4a, 4b. As in the 2 , 4 and 6 shown, the upper edges of the guide elements 16 terminate with an upper support surface 18a, 18b of that cross member segment 4a, 4b on which they are arranged. In the embodiment according to

Fig. 1 und 2 können so die Stützkörper 6 bis zum Anschlag des Seitenträgers 10 abgesenkt werden, so dass die Seitenträger 10 auf der jeweiligen oberen Stützfläche 18a, 18b aufliegen. In einer Konfiguration der Stützvorrichtung 2, bei dem die beiden Seitenträger 10 unterschiedlich weit aus den Führungselementen herausgefahren bzw. auf unterschiedlichen Höhen eingesetzt werden sollen, kann der Querträger 4 direkt unterhalb des tiefergelegenen Seitenträgers 10 positioniert werden. Dies stellt eine besonders stabile Konfiguration der Stützvorrichtung 2 dar. 1 and 2 the support body 6 can be lowered to the stop of the side support 10, so that the side support 10 rests on the respective upper support surface 18a, 18b. In a configuration of the support device 2 in which the two side supports 10 are to be moved out of the guide elements to different extents or used at different heights, the cross support 4 can be positioned directly below the lower side support 10 . This represents a particularly stable configuration of the support device 2.

In allen gezeigten Ausführungsformen (Fig. 1 bis 7) sind die Stützkörper 6 durch herausnehmbare Verriegelungsbolzen 20 an den Führungselementen 16 festgelegt. Dabei sind die beiden gemeinsam an einem Seitenträger 10, 10', 10" angeordneten Stützkörper 6 durch denselben Verriegelungsbolzen 20 gegenüber den Führungselementen 16 festgelegt. Stützkörper 6 und Führungselemente 16 weisen dazu entsprechende Öffnungen bzw. Bohrungen auf. Die Stützkörper 6 sind samt der Seitenträger 10, 10', 10" aus den Führungselementen 16 einfach durch Herausziehen des jeweiligen Verriegelungsbolzens 20 herausnehmbar. Dadurch kann die Stützvorrichtung 2 in einer weiteren Konfiguration verwendet werden, wobei beispielsweise mit der obersten Stützfläche des Querträgers 4, welche von der oberen Stützfläche 18a des äußeren Querträgersegmentes 4a gebildet wird, eine Decke abgestützt wird, während der Seitenträger 10, 10', 10" samt beiden daran angeordneten Stützkörpern 6 eine Randschalung eines oberhalb der Decke zu gießenden Bodenbelags stützt.In all shown embodiments ( Figures 1 to 7 ) the support bodies 6 are fixed to the guide elements 16 by removable locking bolts 20 . The two supporting bodies 6 arranged jointly on a side support 10, 10', 10" are fixed by the same locking bolt 20 in relation to the guide elements 16. Supporting bodies 6 and guide elements 16 have corresponding openings or bores for this purpose. The supporting bodies 6, together with the side supports 10 , 10′, 10″ can be removed from the guide elements 16 simply by pulling out the respective locking bolt 20. As a result, the support device 2 can be used in a further configuration, in which case, for example, a ceiling is supported with the uppermost support surface of the cross member 4, which is formed by the upper support surface 18a of the outer cross member segment 4a, while the side support 10, 10', 10'' together with the two supporting bodies 6 arranged thereon, supports an edge formwork of a floor covering to be poured above the ceiling.

Die Seitenträger 10, 10', 10" sind mit Öffnungen bzw. Bohrungen 21 versehen, durch die ein an der vertikalen Abstützfläche 12 und/oder der horizontalen Abstützfläche 14 anliegendes Schalungselement mittels Schrauben oder anderen Verbindungsm itteln am Seitenträger 10, 10', 10" festgelegt werden kann.The side supports 10, 10', 10" are provided with openings or bores 21, through which a formwork element resting on the vertical support surface 12 and/or the horizontal support surface 14 can be attached to the side support 10, 10', 10" by means of screws or other connecting means. can be specified.

Gemäß der Ausführungsform nach Fig. 3 und 4 weist der Querträger 4 auf seiner Unterseite ein Adapterelement 22 zur Herstellung einer Kraft und/oder formschlüssigen Verbindung mit einer Baustütze auf. Die Baustütze ist dabei nicht Teil der Erfindung. Das Adapterelement 22 kann beispielsweise von einer Baustütze umfasst bzw. umgriffen werden, so dass eine seitliche Verschiebung der Stützvorrichtung 2 gegenüber der Baustütze verhindert wird. Insbesondere weist das Adapterelement 22 ein Gewinde auf, an die eine Baustütze angeschraubt werden kann.According to the embodiment after 3 and 4 the cross member 4 has an adapter element 22 on its underside for establishing a force and/or positive connection with a prop. The prop is not part of the invention. The adapter element 22 can, for example, be encompassed or encompassed by a prop, so that lateral displacement of the support device 2 relative to the prop is prevented. In particular, the adapter element 22 has a thread onto which a prop can be screwed.

Ferner weist im Ausführungsbeispiel gemäß Fig. 3 und 4 einer der Seitenträger ein rohrförmiges Aufnahmeelement 24 auf der in der vertikalen Abstützfläche 12 abgewandten Seite bzw. der Rückseite des Seitenträgers 10 auf. Beispielsweise beim Einsatz als Randschalungsstütze kann ein Teil einer Absturzsicherung in das Aufnahmeelement 24 eingesteckt und fixiert werden.Furthermore, in the embodiment according to 3 and 4 one of the side supports has a tubular receiving element 24 on the side facing away from the vertical support surface 12 or on the rear side of the side support 10 . For example, when used as an edge formwork support, part of a fall protection device can be inserted into the receiving element 24 and fixed.

Im Ausführungsbeispiel gemäß Fig. 5 und 6 ist der Seitenträger 10" in Form einer L-Profilschiene ausgebildet, die eine vertikale Abstützfläche 12 ausbildet und zudem ein Lagerelement 34 ausbildet, so dass ein Schalungselement von oben in das Lagerelement eingesetzt werden kann, wobei das Schalungselement von unten und seitlich abgestützt wird.In the embodiment according to figure 5 and 6 the side support 10" is designed in the form of an L profile rail, which forms a vertical support surface 12 and also forms a bearing element 34 so that a formwork element can be inserted into the bearing element from above, with the formwork element being supported from below and laterally.

Fig. 7 zeigt ein Ausführungsbeispiel, bei dem die Stützvorrichtung 2 ein Lasergerät 26 umfasst, das in einem der Seitenträger 10 angeordnet ist. Das Lasergerät 26 stellt einen Laserstrahl 28 bereit, der parallel zur vertikalen Abstützfläche 12 sowie parallel zur horizontalen Abstützfläche 14 und somit parallel zu einer Längserstreckung des Seitenträgers 10 verläuft. Bei waagerechter Ausrichtung der Seitenträger 10 kann anhand des Laserstrahls 28 die Höhe H gemessen und somit die Höhenlage der Stützvorrichtung 2 kontrolliert werden. Ferner kann ein vertikales Schalungselement 30 auf Ausbeulungen überprüft werden, indem über die Länge des Schalungselementes 30 der Abstand D zwischen Schalungselement 30 und Laserstrahl 28 gemessen wird. Die als Vierkantrohr ausgebildeten Seitenträger 10 weisen beidseitig Endkappen 32 auf, wobei das Lasergerät 26 in einer der Endkappen 32 angeordnet ist. 7 12 shows an exemplary embodiment in which the supporting device 2 comprises a laser device 26 which is arranged in one of the side supports 10. FIG. The laser device 26 provides a laser beam 28 which runs parallel to the vertical support surface 12 and parallel to the horizontal support surface 14 and thus parallel to a longitudinal extent of the side support 10 . When the side supports 10 are aligned horizontally, the height H can be measured using the laser beam 28 and the height position of the supporting device 2 can thus be checked. Furthermore, a vertical formwork element 30 can be checked for bulges by measuring the distance D between the formwork element 30 and the laser beam 28 over the length of the formwork element 30 . The side supports 10 designed as a square tube have end caps 32 on both sides, with the laser device 26 being arranged in one of the end caps 32 .
