Die Erfindung betrifft einen Haltekopf zur lösbaren Verbindung mit dem oberen Ende eines oberen Stützenteils einer Schalungsstütze zur Abstützung eines Schalungsträgers, aufweisend:

  • einen Boden mit einer Oberseite zur Auflage des Schalungsträgers,
  • zumindest ein Halteelement zum Halten eines Längsbereichs des Schalungsträgers,
  • zwei Sicherungselemente zum Eingriff in ein entsprechendes Sicherungselement an einem Kopfteil der Schalungsstütze, wobei die Sicherungselemente Sicherungsstifte sind, welche im Wesentlichen unbeweglich von einer Unterseite des Bodens nach unten abstehen, und
  • ein Verriegelungselement, welches in einem Abstand zu dem Boden verschieblich ist, um den Haltekopf am Kopfteil der Schalungsstütze zu befestigen, wobei das Verriegelungselement im Wesentlichen in Längsrichtung des Haltekopfs verschieblich ist.
The invention relates to a holding head for detachable connection to the upper end of an upper support part of a formwork support for supporting a formwork girder, having:
  • a floor with an upper side for supporting the formwork girder,
  • at least one holding element for holding a longitudinal area of the formwork support,
  • two securing elements for engaging a corresponding securing element on a head part of the formwork support, the securing elements being securing pins which protrude essentially immovably downwards from an underside of the floor, and
  • a locking element which is slidable at a distance from the ground in order to fasten the holding head to the head part of the formwork prop, the locking element being slidable essentially in the longitudinal direction of the holding head.

Weiters betrifft die Erfindung eine Schalungsstütze zur Abstützung eines Schalungsträgers, aufweisend:

  • ein unteres Stützenteil,
  • ein oberes Stützenteil, welches teleskopierbar mit dem unteren Stützenteil verbunden ist, und
  • einen Haltekopf.
The invention also relates to a formwork support for supporting a formwork support, having:
  • a lower support part,
  • an upper support member telescopically connected to the lower support member, and
  • a holding head.

Schließlich betrifft die Erfindung eine Deckenschalung aufweisend:

  • zumindest eine Schalungsstütze,
  • zumindest einen Schalungsträger, welcher lösbar an dem Haltekopf der Schalungsstütze angebracht ist.
Finally, the invention relates to a ceiling formwork having:
  • at least one formwork prop,
  • at least one formwork support which is detachably attached to the retaining head of the formwork prop.

Aus der EP 1 498 557 A1 ist ein Kreuzkopf mit einer Grundplatte offenbart, von welcher zwei lange Rungen und zwei kurze Rungen hochstehen. Weiters ist ein Sicherungsstift in einer Durchbruchöffnung der Grundplatte unverlierbar gehalten, kann allerdings in der Durchbruchöffnung in vertikaler Richtung verschoben werden. Der Sicherungsstift dient dazu, den Kreuzkopf an einer Kopfplatte zu sichern, welche an einem Rohrkörper einer Baustütze vorgesehen ist. Zu diesem Zweck wird der Kreuzkopf bei der Montage gegen die Kopfplatte bzw. die Baustütze verdreht, wodurch Durchbruchöffnungen des Kreuzkopfes mit Durchbruchöffnungen der Kopfplatte der Baustütze zur Deckung gebracht werden. Dadurch werden die Sicherungsstifte soweit abgesenkt, dass die Sicherungsstifte in die Durchbruchöffnungen der Kopfplatte ragen. Im gesicherten Zustand ist der Sicherungsstift vollständig unter die Oberseite der Grundplatte abgesenkt. Beim Verdrehen des Kreuzkopfes gegen die Kopfplatte werden zudem Ränder der Kopfplatte in Seitenschlitze an Lappen eingeschwenkt. Dadurch wird eine Aushubsicherung, d.h. eine Sicherung gegen vertikales Anheben, erzielt.From the EP 1 498 557 A1 discloses a crosshead having a base plate from which two long stanchions and two short stanchions protrude. Furthermore, a locking pin is held captive in a breakthrough opening of the base plate, but can be moved in the breakthrough opening in the vertical direction will. The locking pin serves to secure the crosshead to a head plate which is provided on a tubular body of a prop. For this purpose, the crosshead is twisted against the top plate or the prop during assembly, as a result of which openings in the crosshead are brought into alignment with openings in the top plate of the prop. As a result, the locking pins are lowered so far that the locking pins protrude into the openings in the top plate. When locked, the locking pin is fully lowered below the top of the base plate. When twisting the crosshead against the headstock, edges of the headstock are also pivoted into side slots on tabs. In this way, an excavation safeguard, ie a safeguard against vertical lifting, is achieved.

Nachteilig ist bei diesem Stand der Technik jedoch die umständliche Montage, die Empfindlichkeit gegenüber Verschmutzungen und Beschädigungen und das Spiel, das sich aus der Anordnung der Ränder der Kopfplatte in den Seitenschlitzen des Kreuzkopfes ergibt.The disadvantages of this prior art, however, are the cumbersome assembly, the sensitivity to dirt and damage and the play that results from the arrangement of the edges of the top plate in the side slots of the crosshead.

Die DE 93 18 334 U1 offenbart eine Trägergabel mit einer Grundplatte, die nach oben weisende Gabelzargen an der Oberseite aufweist, um Deckenträger etc. zu halten. An der Unterseite der Grundplatte sind ein gerader Bolzen und ein gebogener Bolzen vorgesehen. Der Bolzen weist ein Querloch auf, in das ein Federstecker oder ein Stecksplint eingeführt werden kann.the DE 93 18 334 U1 discloses a support fork with a base plate having upturned fork legs at the top to hold ceiling supports etc. A straight bolt and a curved bolt are provided on the underside of the base plate. The bolt has a transverse hole into which a spring pin or cotter pin can be inserted.

A holding head according to claim 1 has:
  • a floor with an upper side for supporting the formwork girder,
  • at least one holding element for holding a longitudinal area of the formwork support,
  • at least one securing element for engaging in a corresponding securing element on a head part of the formwork prop, and
  • a locking element which is slidable at a distance from the ground in order to fasten the holding head to the head part of the formwork prop, the locking element being slidable essentially in the longitudinal direction of the holding head.

Erfindungsgemäß ist als Verriegelungselement ein Keil vorgesehen, welcher zwischen einer das Kopfteil der Schalungsstütze festklemmenden Klemmstellung und einer das Kopfteil der Schalungsstütze freigebenden Freigabestellung verschieblich ist, und je ein Halteflansch von den gegenüberliegenden Querseiten des Bodens nach unten absteht, wobei zumindest einer der Halteflansche zumindest eine Halteöffnung zur verschieblichen Aufnahme des Keils aufweist.According to the invention, a wedge is provided as the locking element, which can be displaced between a clamping position that clamps the head part of the formwork prop and a release position that releases the head part of the formwork prop, and one retaining flange each protrudes downward from the opposite transverse sides of the base, with at least one of the retaining flanges having at least one retaining opening for slidably receiving the wedge.

Bei dem erfindungsgemäßen Haltekopf ist ein Verriegelungselement vorgesehen, welches in einem Abstand zu dem Boden verschieblich ist, um den Haltekopf am Kopfteil der Schalungsstütze zu befestigen.In the holding head according to the invention, a locking element is provided which can be displaced at a distance from the ground in order to fasten the holding head to the head part of the formwork prop.

Somit wird der Haltekopf im montierten Zustand durch das Sicherungselement einerseits und das verschiebliche Verriegelungselement andererseits lösbar an dem Kopfteil, insbesondere an einer Kopfplatte, der Schalungsstütze gehalten. Der Eingriff des Sicherungselements am Haltekopf in das entsprechende Sicherungselement am Kopfteil bewirkt eine formschlüssige Verbindung, welche den Haltekopf im montierten Zustand gegen eine Verdrehung des Haltekopfs um die Längsachse der Schalungsstütze sichert. Andererseits ist das Verriegelungselement dazu eingerichtet, den Haltekopf gegen ein Abheben vom oberen Stützenteil zu sichern. Zu diesem Zweck kann das Verriegelungselement von einer Freigabestellung, in welcher das Abheben des Haltekopfs vom oberen Stützenteil noch möglich ist, in eine Verriegelungsstellung verschoben werden, in welcher das Abheben des Haltekopfs vom oberen Stützenteil blockiert ist. Vorteilhafterweise ist die Verschiebung des Verriegelungselements unabhängig vom Eingriff des Sicherungselements am Haltekopf in das entsprechende Sicherungselement an der Schalungsstütze. Durch das verschiebliche Verriegelungselement kann die Anbringung des Haltekopfs am Stützenende wesentlich sicherer und zuverlässiger als beim Stand der Technik gemäß der EP 1 482 105 bewerkstelligt werden, bei welchem die Ränder der Kopfplatte - gleichzeitig mit der Anordnung des Sicherungsstiftes des Kreuzkopfes in der zugehörigen Durchbruchsöffnung an der Kopfplatte - in die Seitenschlitze am Kreuzkopf eingeschwenkt werden mussten. Vorteilhafterweise kann der Haltekopf zudem besonders einfach, auch im stehenden Zustand der Schalungsstütze, montiert werden. Bei der Montage wird zuerst der Haltekopf auf das Kopfteil am oberen Stützenteil aufgesetzt, so dass das Sicherungselement am Haltekopf in das korrespondierende Sicherungselement am Kopfteil eingreift, um eine Drehsicherung des Haltekopfs gegenüber dem oberen Stützenteil zu erzielen. Anschließend wird das Verriegelungselement von der Freigabestellung in die Verriegelungsstellung verschoben, um den Haltekopf lösbar am oberen Stützenteil zu befestigen.Thus, in the assembled state, the holding head is releasably held on the head part, in particular on a head plate, of the formwork support by the securing element on the one hand and the displaceable locking element on the other hand. The intervention of Securing element on the retaining head in the corresponding securing element on the head part causes a positive connection, which secures the retaining head in the assembled state against rotation of the retaining head about the longitudinal axis of the formwork prop. On the other hand, the locking element is designed to secure the holding head against lifting off the upper support part. For this purpose, the locking element can be moved from a release position, in which the lifting of the holding head from the upper support part is still possible, into a locking position, in which the lifting of the holding head from the upper support part is blocked. The displacement of the locking element is advantageously independent of the engagement of the securing element on the holding head in the corresponding securing element on the formwork support. Due to the sliding locking element, the attachment of the holding head at the support end can be much safer and more reliable than in the prior art according to EP 1 482 105 be accomplished, in which the edges of the headstock - at the same time as the arrangement of the locking pin of the crosshead in the associated breakthrough opening on the headstock - had to be pivoted into the side slots on the crosshead. Advantageously, the retaining head can also be mounted particularly easily, even when the formwork support is in the upright position. During assembly, the holding head is first placed on the head part on the upper support part, so that the securing element on the holding head engages in the corresponding securing element on the head part in order to secure the holding head against rotation relative to the upper support part. The locking element is then shifted from the release position to the locking position in order to releasably attach the holding head to the upper support part.

Für die Zwecke dieser Offenbarung beziehen sich die Orts- und Richtungsangaben, wie "horizontal", "vertikal" etc., auf einen bestimmungsgemäßen Gebrauchszustand des Haltekopfs bei vertikaler Ausrichtung der Schalungsstütze. "Lösbar" bedeutet, dass die Verbindung ohne erhebliche Funktionseinbußen mehrmals, vorzugsweise werkzeuglos, hergestellt und wieder gelöst werden kann.For the purposes of this disclosure, the location and direction information, such as "horizontal", "vertical" etc., relate to an intended use state of the holding head when the formwork support is aligned vertically. "Releasable" means that the connection can be made and released again several times, preferably without tools, without significant functional losses.

In einer bevorzugten Ausführungsform sind zwei Halteelemente an gegenüberliegenden Längsseiten des Haltekopfs dazu eingerichtet, die gegenüberliegenden Längsbereiche eines unteren Gurts des Schalungsträgers zu halten.In a preferred embodiment, two holding elements on opposite long sides of the holding head are designed to to hold the opposite longitudinal portions of a lower chord of the formwork girder.

In einer bevorzugten Ausführung ist als Halteelement ein Umgreifelement vorgesehen, welches einen der seitlichen Längsbereiche des unteren Gurts des Schalungsträgers umgreift, d.h. seitlich und oben festhält. Bevorzugt sind zwei Umgreifelemente zum Umgreifen der beiden gegenüberliegenden Längsbereiche des Schalungsträgers vorgesehen.In a preferred embodiment, a gripping element is provided as the holding element, which grips around one of the lateral longitudinal areas of the lower chord of the formwork girder, i.e. holds it in place at the side and at the top. Two gripping elements are preferably provided for gripping around the two opposite longitudinal regions of the formwork support.

Um einen seitlichen Überstand des Verriegelungselements über die Längsseite des Schalungsträgers in Gebrauch hinaus zu verhindern, ist es günstig, dass das Verriegelungselement im Wesentlichen in Längsrichtung des Haltekopfs, also in Längsrichtung des Schalungsträgers, verschieblich ist.In order to prevent the locking element from protruding laterally beyond the long side of the formwork support during use, it is favorable for the locking element to be displaceable essentially in the longitudinal direction of the holding head, ie in the longitudinal direction of the formwork support.

Um eine Verklemmung des Haltekopfs an der Schalungsstütze zu erzielen, ist erfindungsgemäß als Verriegelungselement ein Keil vorgesehen, welcher zwischen einer das Kopfteil der Schalungsstütze festklemmenden Klemmstellung und einer das Kopfteil der Schalungsstütze freigebenden Freigabestellung verschieblich ist. Zu diesem Zweck weist der Keil zumindest eine in Einschubrichtung verjüngte Keilfläche auf, so dass der Keil umso stärker gegen die Unterseite der Kopfplatte der Schalungsstütze gepresst wird, desto weiter der Keil in Richtung der Klemmstellung vorgeschoben wird. Vorteilhafterweise kann bei dieser Ausführungsform ein Spiel zwischen dem Haltekopf und der Schalungsstütze vermieden werden. Durch die formschlüssige Verbindung mittels des Sicherungselements einerseits und die kraftschlüssige Verbindung mittels des Keils andererseits wird der Haltekopf besonders sicher an der Schalungsstütze fixiert. Weiters ist diese Ausführung unempfindlich für Verschmutzungen. Auch die Montage ist besonders einfach.In order to achieve clamping of the retaining head on the formwork prop, a wedge is provided according to the invention as a locking element which can be displaced between a clamping position clamping the head part of the formwork prop and a release position releasing the head part of the formwork prop. For this purpose, the wedge has at least one wedge surface that tapers in the direction of insertion, so that the further the wedge is pushed forward in the direction of the clamping position, the more the wedge is pressed against the underside of the head plate of the formwork prop. In this embodiment, play between the holding head and the formwork support can advantageously be avoided. The retaining head is particularly securely fixed to the formwork support by the positive connection by means of the securing element on the one hand and the non-positive connection by means of the wedge on the other hand. Furthermore, this version is insensitive to contamination. Installation is also particularly easy.

Um eine sichere Fixierung des Haltekopfs an der Schalungsstütze zu ermöglichen, ist es von Vorteil, wenn der Keil zwei in einem Abstand, insbesondere in Querrichtung des Haltekopfs, zueinander angeordnete Keilteile aufweist. Im montierten Zustand befindet sich das obere Stützenteil zwischen den zwei Keilteilen des Keils. Der Haltekopf wird bei dieser Ausführung besonders sicher an der Schalungsstütze gehalten, da Kippmomente auf den Haltekopf wirksam auf den oberen Stützenteil abgeleitet werden.In order to enable the holding head to be securely fixed to the formwork support, it is advantageous if the wedge has two wedge parts which are arranged at a distance from one another, in particular in the transverse direction of the holding head. When assembled, the upper support part is located between the two wedge parts of the wedge. The holding head is particularly secure with this design held on the formwork prop, as tilting moments on the retaining head are effectively diverted to the upper part of the prop.

Um die Verschiebung des Keils einfach und zuverlässig zu gestalten, ist erfindungsgemäß vorgesehen, dass je ein Halteflansch von den gegenüberliegenden Querseiten des Bodens nach unten absteht, wobei zumindest einer der Halteflansche zumindest eine Halteöffnung zur verschieblichen Aufnahme des Keils aufweist. In einer bevorzugten Ausführung sind die Halteflansche einteilig mit dem Boden gebildet, beispielsweise durch Umbiegen an den Querseiten des Bodens. Bevorzugt weisen die Halteflansche jeweils zwei Halteöffnungen auf, in denen die zwei Keilteile des Keils verschieblich geführt sind.In order to make the displacement of the wedge simple and reliable, it is provided according to the invention that a retaining flange protrudes downwards from the opposite transverse sides of the base, with at least one of the retaining flanges having at least one retaining opening for slidably receiving the wedge. In a preferred embodiment, the retaining flanges are formed in one piece with the base, for example by bending at the transverse sides of the base. Preferably, the retaining flanges each have two retaining openings, in which the two wedge parts of the wedge are displaceably guided.

Als Sicherungselement ist ein Sicherungsstift vorgesehen, welcher im Wesentlichen unbeweglich von einer Unterseite des Bodens nach unten absteht. Beim Aufsetzen des Haltekopfs auf die Kopfplatte der Schalungsstütze wird der Sicherungsstift in das entsprechende Sicherungselement in Form einer Sicherungsöffnung an der Kopfplatte der Schalungsstütze eingefügt. Um eine wirksame Verdrehsicherung zu erzielen, ist der Sicherungsstift vorzugsweise im Wesentlichen passgenau in der Sicherungsöffnung angeordnet. Dadurch wird eine formschlüssige Verbindung zwischen dem Haltekopf und der Schalungsstütze geschaffen, welche anschließend durch das Verriegelungselement gesichert werden kann.A safety pin is provided as a safety element, which essentially immovably protrudes downwards from an underside of the floor. When the retaining head is placed on the top plate of the formwork prop, the safety pin is inserted into the corresponding safety element in the form of a safety opening on the top plate of the formwork prop. In order to achieve effective anti-twist protection, the locking pin is preferably arranged with an essentially precise fit in the locking opening. This creates a positive connection between the holding head and the formwork support, which can then be secured by the locking element.

Bei dem erfindungsgemäßen Haltekopf sind zwei Sicherungselemente, nämlich zwei Sicherungsstifte, vorgesehen. Bevorzugt sind die Sicherungselemente an gegenüberliegenden Längsseiten des Bodens, insbesondere jeweils einem Halteelement, insbesondere Umgreifelement, gegenüberliegend, angeordnet. Im montierten Zustand des Haltekopfs erstrecken sich die Längsseiten im Wesentlichen parallel zur Längsachse des Schalungsträgers.Two securing elements, namely two securing pins, are provided in the holding head according to the invention. The securing elements are preferably arranged on opposite longitudinal sides of the base, in particular opposite a holding element, in particular a gripping element. In the mounted state of the holding head, the longitudinal sides extend essentially parallel to the longitudinal axis of the formwork support.

Um den Schalungsträger in der bestimmungsgemäßen Gebrauchslage am Haltekopf zu halten, ist es günstig, wenn ein Verdrehsicherungselement zur Sicherung des Schalungsträgers gegen ein Verdrehen vorgesehen ist. Durch das Verdrehsicherungselement wird ein Verdrehen des Schalungsträgers um eine vertikale Achse (parallel zur Längsachse der Schalungsstütze) relativ zum Haltekopf vermieden.In order to hold the formwork support in the intended position of use on the holding head, it is advantageous if an anti-rotation element is provided to secure the formwork support against twisting. The anti-rotation element prevents the formwork support from rotating about a vertical axis (parallel to the longitudinal axis of the formwork support) relative to the retaining head avoided.

Zu diesem Zweck weist das Verdrehsicherungselement bevorzugt eine Feder auf, welche zwischen einer den Schalungsträger gegen Verdrehen sichernden Sicherungsstellung und einer das Verdrehen des Schalungsträgers freigebenden Montage- bzw. Demontagestellung beweglich ist. Die Feder ist in der Sicherungsstellung bevorzugt im entspannten Zustand und in der Montage- bzw. Demontagestellung im gespannten Zustand angeordnet. Bei der Montage des Schalungsträgers kann die Feder durch das Aufsetzen des Schalungsträgers gespannt werden. Bei Erreichen der Gebrauchsstellung des Schalungsträgers wird die Feder freigegeben, entspannt und so in die Sicherungsstellung gedrückt. Bei der Demontage des Schalungsträgers vom Haltekopf wird die Feder gegen die Federkraft in die Demontagestellung gedrückt, damit der Schalungsträger derart in eine Freigabestellung verdreht werden kann, dass die Umgreifelemente vom unteren Gurt des Schalungsträgers gelöst werden und so der Schalungsträger vom Haltekopf abgenommen werden kann.For this purpose, the anti-twist element preferably has a spring which can be moved between a locking position that secures the formwork support against twisting and an assembly or disassembly position that releases the formwork support from twisting. The spring is preferably arranged in the relaxed state in the securing position and in the tensioned state in the assembly or disassembly position. When assembling the formwork girder, the spring can be tensioned by placing the formwork girder in place. When the formwork support reaches the position of use, the spring is released, relaxed and thus pressed into the securing position. When dismantling the formwork support from the holding head, the spring is pressed against the spring force into the dismantling position so that the formwork support can be rotated into a release position in such a way that the gripping elements are released from the lower strap of the formwork support and the formwork support can thus be removed from the holding head.

Gemäß einer bevorzugten Ausführungsform weist die Feder einen Federbügel auf, welcher zwischen der Sicherungsstellung und der Montage- bzw. Demontagestellung verschwenkbar ist.According to a preferred embodiment, the spring has a spring clip which can be pivoted between the securing position and the assembly or disassembly position.

Um das Abnehmen des Schalungsträgers vom Haltekopf zu erleichtern, weist die Feder bevorzugt eine Ausbuchtung zur vorübergehenden Anbringung eines Werkzeugs zum Überführen der Feder von der Sicherungsstellung in die Demontagestellung auf.In order to facilitate the removal of the formwork support from the holding head, the spring preferably has a bulge for temporarily attaching a tool for transferring the spring from the securing position to the dismantling position.

Um die Überführung der Feder von der Montage- bzw. Demontagestellung in die Sicherungsstellung zu ermöglichen, ist es günstig, wenn der Boden eine Aussparung aufweist, wobei ein Halteabschnitt der Feder in der Sicherungsstellung durch die Aussparung nach oben vorsteht und in der Montage- bzw. Demontagestellung in die Aussparung abgesenkt ist. Bei der Montage wird der Schalungsträger schräg auf den Haltekopf aufgesetzt, so dass die Feder durch den Schalungsträger in die Aussparung gedrückt wird. Durch Verdrehen des Schalungsträgers wird das Halteelement am unteren Gurt des Schalungsträgers ausgerichtet. Mit Erreichen der bestimmungsgemäßen Gebrauchsstellung des Schalungsträgers wird der Halteabschnitt der Feder freigegeben, welcher durch die Federvorspannung nach oben in die Sicherungsstellung gedrückt wird, in welcher der Halteabschnitt der Feder seitlich am unteren Gurt des Schalungsträgers anliegt.In order to enable the spring to be transferred from the assembly or disassembly position to the securing position, it is advantageous if the base has a recess, with a retaining section of the spring protruding upwards through the recess in the securing position and in the assembly or Dismantling position is lowered into the recess. During assembly, the formwork support is placed at an angle on the retaining head so that the spring is pressed into the recess by the formwork support. By twisting the formwork girder, the retaining element is aligned with the lower chord of the formwork girder. When the formwork support reaches its intended use position the holding section of the spring is released, which is pressed upwards by the spring preload into the securing position, in which the holding section of the spring rests laterally on the lower chord of the formwork girder.

Um eine günstige Federwirkung zu erzeugen, weist die Feder bevorzugt einen Betätigungsabschnitt unterhalb des Bodens auf. Dadurch wird auch das Überführen der Feder in die Demontagestellung erleichtert, indem die Feder am Betätigungsabschnitt nach unten gezogen wird.In order to produce a favorable spring effect, the spring preferably has an actuating section below the base. This also makes it easier to move the spring into the dismantling position by pulling the spring down on the actuating section.

Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels weiter erläutert.

Fig. 1 zeigt eine Deckenschalung 1 mit Teleskop-Schalungsstützen 2, welche, wie üblich, jeweils einen unteren Stützenteil 3 in Form eines Außenrohrs und einen darin verschieblichen oberen Stützenteil 4 in Form eines Innenrohrs aufweisen. Die Länge der Teleskop-Schalungsstütze 2 wird mittels eines Absteckelements 5 eingestellt. Zur Feineinstellung der Länge der Schalungsstütze 2 ist eine Mutter vorgesehen, welche auf ein Außengewinde des unteren Stützenteils 3 geschraubt ist. Die Schalungsstützen 2 weisen an den oberen Enden des oberen Stützenteils 4 Halte- bzw. Stützköpfe 6 auf, auf denen Schalungsträger 7 abgestützt sind. Auf den Oberseiten der Schalungsträger 7 sind, im Wesentlichen senkrecht dazu, Querträger 8 angeordnet, auf denen wiederum Schalungsplatten 9 aufgelegt sind. Die Oberseiten der Schalungsplatten 9 bilden die Schalhaut, auf welcher ein Deckenelement (bzw. ein Bodenelement) aus Beton gegossen wird. Der besseren Übersicht halber sind in Fig. 1 nicht alle Querträger 8 und Schalungsplatten 9 eingezeichnet. In der gezeigten Ausführung weisen die Schalungsstützen 2 an den seitlichen Randbereichen der Deckenschalung 1 jeweils mehrere Stützbeine 10 auf, welche an einer Bodenfläche 11 abgestützt sind. Demgegenüber sind die Schalungsstützen 2 im Inneren der Deckenschalung 1, zwischen den seitlichen Rändern der Deckenschalung 1 frei von solchen Stützbeinen 10, so dass die Schalungsstützen 2 nur über Fußplatten 12 an den unteren Enden der unteren Stützenteile 3 an der Bodenfläche 11 abgestützt sind. Dadurch bleibt mehr Raum zwischen den Schalungsstützen 2. 1 shows a slab formwork 1 with telescopic formwork supports 2 which, as usual, each have a lower support part 3 in the form of an outer tube and an upper support part 4 in the form of an inner tube that can be displaced therein. The length of the telescopic formwork prop 2 is set using a locking element 5 . A nut is provided for fine adjustment of the length of the formwork support 2 and is screwed onto an external thread of the lower support part 3 . The formwork supports 2 have at the upper ends of the upper support part 4 holding or supporting heads 6, on which formwork supports 7 are supported. Arranged on the upper sides of the formwork supports 7, essentially perpendicular thereto, are transverse supports 8, on which formwork panels 9 are in turn placed. The tops of the formwork panels 9 form the formwork skin on which a ceiling element (or a floor element) is cast from concrete. For the sake of a better overview, 1 not all crossbeams 8 and formwork panels 9 are drawn. In the embodiment shown, the formwork supports 2 each have a plurality of support legs 10 on the lateral edge regions of the ceiling formwork 1 , which are supported on a floor surface 11 . In contrast, the formwork supports 2 inside the ceiling formwork 1, between the lateral edges of the ceiling formwork 1 free of such support legs 10, so that the formwork supports 2 are supported only via base plates 12 at the lower ends of the lower support parts 3 on the floor surface 11. This leaves more space between the formwork props 2.

Wie aus Fig. 2 bis Fig. 4 ersichtlich, weisen die Schalungsträger 7 jeweils einen oberen Gurt 13, einen unteren Gurt 14 und einen den oberen Gurt 13 mit dem unteren Gurt 14 verbindenden Steg 15 auf, so dass die Schalungsträger 7 im Querschnitt (senkrecht zur Längsachse) I-förmig sind. Der obere Gurt 13, der untere Gurt 14 und der Steg 15 sind in der gezeigten Ausführung jeweils überwiegend aus einem Holzwerkstoff gebildet. An den Enden des Schalungsträgers 7 sind Schutzkappen 16 aus Kunststoff vorgesehen. Am ersten Ende des Schalungsträgers 7 ist weiters eine erste Verbindungslasche 17 mit einem ersten Kopplungsteil 18 und am zweiten Ende des Schalungsträgers 7 ist eine zweite Verbindungslasche 19 mit einem zweiten Kopplungsteil 20 montiert. Die erste und die zweite Verbindungslasche 19 sind aus Metall, vorzugsweise Stahl oder Aluminium, oder aus einem Kunststoff gefertigt.How out Figures 2 to 4 As can be seen, the formwork supports 7 each have an upper chord 13, a lower chord 14 and a web 15 connecting the upper chord 13 to the lower chord 14, so that the formwork supports 7 are I-shaped in cross section (perpendicular to the longitudinal axis). In the embodiment shown, the upper chord 13, the lower chord 14 and the web 15 are each predominantly formed from a wooden material. Protective caps 16 made of plastic are provided at the ends of the formwork support 7 . A first connecting strap 17 with a first coupling part 18 is also mounted on the first end of the formwork support 7 and a second connecting strap 19 with a second coupling part 20 is mounted on the second end of the formwork support 7 . The first and the second connecting strap 19 are made of metal, preferably steel or aluminum, or made of a plastic.

Wie aus Fig. 5 und Fig. 6 ersichtlich, können die Schalungsträger 7 paarweise durch Einhängen des ersten Kopplungsteils 18 des einen Schalungsträgers 7 in das zweite Kopplungsteil 20 des anderen Schalungsträgers 7 miteinander verbunden werden. Somit sind das erste Kopplungsteil 18 und das zweite Kopplungsteil 20 für eine lösbare Verbindung miteinander eingerichtet. Als erstes Kopplungsteil 18 ist ein Bolzen 21, als zweites Kopplungsteil 20 eine Bolzenaufnahme 22 in Form einer nach oben offenen Vertiefung vorgesehen. Die zweite Verbindungslasche 19 weist zudem ein Führungselement 23 auf, welches von dem zweiten Kopplungsteil 20, hier der Bolzenaufnahme 20, schräg nach oben absteht, um das Einhängen des Bolzens 21 in die Bolzenaufnahme 22 zu erleichtern. In einem vertikalen Abstand zur Bolzenaufnahme 22 weist die zweite Verbindungslasche 19 ein Rückhalteelement 24 auf, welches die Bolzenaufnahme 22 überdeckt, so dass der Bolzen 21 bei einem vertikalen Anheben gegen das Rückhalteelement 24 stößt. Dadurch wird eine Aushubsicherung des Schalungsträgers 7 erzielt. Als Rückhalteelement 24 ist in der gezeigten Ausführung ein Plattenteil vorgesehen, welches die Bolzenaufnahme 22 vollständig überdeckt.How out 5 and 6 As can be seen, the formwork supports 7 can be connected to one another in pairs by hooking the first coupling part 18 of one formwork support 7 into the second coupling part 20 of the other formwork support 7 . The first coupling part 18 and the second coupling part 20 are thus set up for a detachable connection to one another. A bolt 21 is provided as the first coupling part 18 , and a bolt receptacle 22 in the form of a depression open at the top is provided as the second coupling part 20 . The second connecting bracket 19 also has a guide element 23 which protrudes obliquely upwards from the second coupling part 20, here the bolt receptacle 20, in order to facilitate the hanging of the bolt 21 into the bolt receptacle 22. At a vertical distance from the bolt receptacle 22, the second connecting strap 19 has a retaining element 24, which covers the bolt receptacle 22, so that the bolt 21 abuts against the retaining element 24 when it is lifted vertically. As a result, the formwork support 7 is secured against excavation. As a retaining element 24 is in the embodiment shown a plate part is provided which completely covers the bolt receptacle 22 .

Wie aus Fig. 5 und Fig. 6 weiters ersichtlich, weisen die erste Verbindungslasche 17 und die zweite Verbindungslasche 19 jeweils einen oberen Stützteil 25 in Kontakt mit der Innenseite 13a (d.h. mit der von der Schalungsplatte 9 abgewandten Seite) des oberen Gurts 13 und einen unteren Stützteil 26 in Kontakt mit der Innenseite 14a (d.h. mit der von der Schalungsstütze 2 abgewandten Seite) des unteren Gurts 14 des Schalungsträgers 7 auf. Somit wird eine günstige Lastabtragung im verbundenen Zustand der Schalungsträger 7 erzielt.How out 5 and 6 further visible, the first connecting strap 17 and the second connecting strap 19 each have an upper support part 25 in contact with the inner side 13a (i.e. with the side facing away from the formwork panel 9) of the upper chord 13 and a lower support part 26 in contact with the inner side 14a (ie with the side facing away from the formwork support 2) of the lower belt 14 of the formwork girder 7. In this way, favorable load transfer is achieved when the formwork supports 7 are in the connected state.

Wie insbesondere aus Fig. 9 und Fig. 10 ersichtlich, weisen die erste Verbindungslasche 17 und die zweite Verbindungslasche 19 jeweils einen Befestigungsschenkel 27 an den gegenüberliegenden Längsseiten 15a des Stegs 15 auf. Die Befestigungsschenkel 27 sind so auf den Steg 15 aufgeschoben, dass das erste Kopplungselement 18 vor der ersten Stirnseite des I-förmigen Längsabschnitts des Schalungsträgers 7 und das zweite Kopplungselement 20 vor der zweiten Stirnseite des I-förmigen Längsabschnitts des Schalungsträgers 7 angeordnet ist. Am ersten und zweiten Ende weist der Steg 15 des Schalungsträgers 7 jeweils zumindest eine Durchgangsöffnung 28, hier zwei Durchgangsöffnungen 28 in Längsabständen zueinander, auf, welche im montierten Zustand mit Befestigungsöffnungen 29 der ersten Verbindungslasche 17 bzw. der zweiten Verbindungslasche 19 fluchten, um die Anordnung von Befestigungselementen 30, hier Schrauben, zu ermöglichen.Like in particular 9 and 10 As can be seen, the first connecting strap 17 and the second connecting strap 19 each have a fastening leg 27 on the opposite longitudinal sides 15a of the web 15 .
