Definitions

  • ceiling formwork with longitudinal and transverse girders for supporting formwork panels are known (cf. WO 2016/116543 ).
  • the side members are mounted on the holding heads of formwork props.
  • the cross members are placed on the side members, essentially across them.
  • formwork panels are placed on the cross members.
  • the side members have a predetermined length.
  • several longitudinal beams are arranged one behind the other per row.
  • the successive longitudinal beams are offset somewhat laterally, so that the ends of the longitudinal beams can be arranged to overlap.
  • the side members are usually supported in the overlapping area with a formwork prop.
  • the longitudinal beams remain displaceable relative to one another in the longitudinal direction, which can result in instability of the ceiling formwork without additional measures, such as support legs.
  • slab formworks are also known in which the ends of the side members are attached directly to the formwork supports in the heads. From a static point of view, however, there are no significant improvements.
  • the object of the present invention is to alleviate at least individual disadvantages of the prior art or to eliminate.
  • the aim of the invention is, in particular, to create a formwork support with which the stability of a ceiling formwork can be increased and the use of formwork props and the necessary support legs can be reduced.
  • a first connecting strap with a first coupling part for releasable longitudinal connection with a second coupling part of a further formwork support is mounted at the first end of the formwork support.
  • two formwork beams according to the invention are coupled to one another via the corresponding coupling parts on the facing end faces of the formwork beams in such a way that the longitudinal axes of the formwork beams are arranged essentially in line, i.e. collinear, and longitudinal displacement of the connected formwork beams is blocked against each other.
  • the formwork supports can thus be releasably connected to one another at the end faces in order to effect a transmission of force along the formwork supports.
  • the stability of the ceiling formwork can advantageously be increased significantly in this way. It is particularly advantageous that a continuous beam effect is achieved which can be taken into account for the necessary load-bearing capacity of the ceiling props. This means that the number of formwork props can be reduced.
  • the first connecting strap is mounted on the first end of the formwork support, ie attached to the first end of the formwork support via a fastening device.
  • the first connecting strap is designed as an adapter, which in particular can also be attached to conventional formwork supports.
  • the location and direction information such as “horizontal”, “vertical”, “top”, “bottom”, refer to a horizontal state of use of the formwork support. “Detachable” means that a connection can be established and released several times, preferably without tools, without significant loss of functionality.

  • the first and the second coupling part preferably differ from one another in order to enable a simple connection of the formwork supports. It is therefore advantageous if the first coupling part is designed as a suspension element and the second coupling part as a receiving element. In this embodiment, the first coupling part is hooked into the second coupling part from above.
  • the first and second connecting tabs are preferably made of metal, preferably steel or aluminum, or of a plastic.
  • a bolt is provided as the first coupling part and / or a bolt receptacle is provided as the second coupling part.

  • the second connecting strap has a retaining element above the bolt receptacle for securing against excavation.
  • the retaining element above i.e. at a vertical distance from the bolt receptacle, prevents the formwork carrier from being accidentally lifted vertically upwards from the horizontal position of use.
  • the formwork carrier is pivoted down, the retaining element not being effective in the pivoted down position of the formwork carrier in order to enable the formwork carrier to be removed.
  • the retaining element is movably arranged on the first connecting strap in order to be transferred from an operative position into a dismantling position.

  • the first connecting strap has a respective fastening leg on opposite longitudinal sides of the web.
  • the first and second fastening legs are preferably designed as fastening plates which are arranged essentially parallel to the web. This enables stable fastening of the first connecting strap on the formwork support.
  • the first and second fastening legs preferably do not protrude laterally beyond the upper and lower chords of the formwork support.
  • the second connecting strap preferably also has a first and a second fastening leg, so that reference can be made to the explanations given above.
  • the web has at least one through opening at the first end through which a fastening element, in particular a screw, of the first connecting strap is guided.

  • a particular advantage of this embodiment is that many formwork supports already have such a through opening (eg for attaching a crane suspension or a side protection adapter), which can thus be used for retrofitting the first connecting bracket.

Description

Die Erfindung betrifft einen Schalungsträger, aufweisend:

  • einen oberen Gurt,
  • einen unteren Gurt und
  • einen Steg, welcher den oberen Gurt mit dem unteren Gurt verbindet.
The invention relates to a formwork support, comprising:
  • an upper strap,
  • a lower strap and
  • a web that connects the upper belt to the lower belt.

Weiters betrifft die Erfindung eine Schalungstragvorrichtung, aufweisend:

  • einen Schalungsträger und
  • einen weiteren Schalungsträger.
The invention also relates to a formwork support device, comprising:
  • a formwork beam and
  • another formwork beam.

Schließlich betrifft die Erfindung eine Deckenschalung, aufweisend:

  • mehrere Schalungstragvorrichtungen, und
  • mehrere Schalungsstützen zur Abstützung der Schalungstragvorrichtungen.
Finally, the invention relates to a ceiling formwork, comprising:
  • several formwork support devices, and
  • several formwork props to support the formwork support devices.

Im Stand der Technik sind Deckenschalungen mit Längs- und Querträgern zur Auflage von Schalungsplatten bekannt (vgl. z.B. WO 2016/116543 ). Die Längsträger werden dabei an den Halteköpfen von Schalungsstützen montiert. Die Querträger werden auf den Längsträgern, im Wesentlichen quer dazu, aufgelegt. Zum Schluss werden Schalungsplatten auf die Querträger gelegt. Die Längsträger haben eine vorgegebene Länge. Je nach Dimension der Deckenschalung werden daher mehrere Längsträger pro Reihe hintereinander angeordnet. Die aufeinanderfolgenden Längsträger werden dafür seitlich etwas versetzt, so dass die Enden der Längsträger überlappend angeordnet werden können. Die Längsträger werden üblicherweise im Überlappungsbereich mit einer Schalungsstütze abgestützt. Nachteiligerweise bleiben die Längsträger jedoch in Längsrichtung gegeneinander verschieblich, wodurch ohne zusätzliche Maßnahmen, wie z.B. Stützbeine, eine Instabilität der Deckenschalung entstehen kann.In the prior art, ceiling formwork with longitudinal and transverse girders for supporting formwork panels are known (cf. WO 2016/116543 ). The side members are mounted on the holding heads of formwork props. The cross members are placed on the side members, essentially across them. Finally, formwork panels are placed on the cross members. The side members have a predetermined length. Depending on the dimensions of the slab formwork, several longitudinal beams are arranged one behind the other per row. For this purpose, the successive longitudinal beams are offset somewhat laterally, so that the ends of the longitudinal beams can be arranged to overlap. The side members are usually supported in the overlapping area with a formwork prop. Disadvantageously, however, the longitudinal beams remain displaceable relative to one another in the longitudinal direction, which can result in instability of the ceiling formwork without additional measures, such as support legs.

Im Stand der Technik sind weiters Deckenschalungen bekannt, bei denen die Längsträger direkt mit ihren Enden in Köpfe an den Schalungsstützen eingehängt sind. Aus statischer Sicht ergeben sich hierbei jedoch keine wesentlichen Verbesserungen. Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, zumindest einzelne Nachteile des Standes der Technik zu lindern bzw. zu beseitigen. Die Erfindung setzt sich insbesondere zum Ziel, einen Schalungsträger zu schaffen, mit welchem die Stabilität einer Deckenschalung erhöht und der Einsatz von Schalungsstützen und den dafür nötigen Stützbeinen reduziert werden kann.In the prior art, slab formworks are also known in which the ends of the side members are attached directly to the formwork supports in the heads. From a static point of view, however, there are no significant improvements. In contrast, the object of the present invention is to alleviate at least individual disadvantages of the prior art or to eliminate. The aim of the invention is, in particular, to create a formwork support with which the stability of a ceiling formwork can be increased and the use of formwork props and the necessary support legs can be reduced.

Diese Aufgabe wird durch eine Schalungsstütze mit den Merkmalen von Anspruch 1, eine Stützeinrichtung mit den Merkmalen von Anspruch 8 und eine Deckenschalung mit den Merkmalen von Anspruch 12 erreicht. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.This object is achieved by a formwork prop with the features of claim 1, a support device with the features of claim 8 and a ceiling formwork with the features of claim 12. Preferred embodiments are given in the dependent claims.

Erfindungsgemäß ist am ersten Ende des Schalungsträgers eine erste Verbindungslasche mit einem ersten Kopplungsteil zur lösbaren Längsverbindung mit einem zweiten Kopplungsteil eines weiteren Schalungsträgers montiert.According to the invention, a first connecting strap with a first coupling part for releasable longitudinal connection with a second coupling part of a further formwork support is mounted at the first end of the formwork support.

Bei Verwendung in einer Deckenschalung sind zwei erfindungsgemäße Schalungsträger über die korrespondierenden Kopplungsteile an den aufeinandertreffenden Stirnseiten der Schalungsträger derart miteinander gekoppelt, dass die Längsachsen der Schalungsträger im Wesentlichen in Linie, d.h. kollinear, angeordnet sind und eine Längsverschiebung der verbundenen Schalungsträger gegeneinander gesperrt ist. Somit können die Schalungsträger an den Stirnseiten lösbar miteinander verbunden werden, um eine Kraftübertragung entlang der Schalungsträger zu bewirken. Vorteilhafterweise kann so die Stabilität der Deckenschalung wesentlich erhöht werden. Günstig ist insbesondere, dass eine Durchlaufträgerwirkung erzielt wird, welche für die notwendige Traglast der Deckenstützen berücksichtigt werden kann. Somit kann die Zahl der Schalungsstützen reduziert werden. Weiters ist es nicht erforderlich, einen seitlichen Versatz zwischen den aufeinanderfolgenden Schalungsträgern vorzusehen, um einen Überlappungsbereich an den Endbereichen zu schaffen. Vorteilhaft ist weiters, dass eine Unterstellung der verbundenen Schalungsträger an der Längsverbindung nicht erforderlich ist. Bei einer bevorzugten Ausführungsform ist daher der Kopplungsbereich zwischen den zwei Schalungsträgern frei von einer Unterstellung mit einer Schalungsstütze. Die erste Verbindungslasche ist am ersten Ende des Schalungsträger montiert, d.h. über eine Befestigungsvorrichtung am ersten Ende des Schalungsträgers angebracht. Vorteilhafterweise ist die erste Verbindungslasche so als Adapter ausgebildet, welche insbesondere auch an herkömmlichen Schalungsträgern befestigt werden kann.When used in a ceiling formwork, two formwork beams according to the invention are coupled to one another via the corresponding coupling parts on the facing end faces of the formwork beams in such a way that the longitudinal axes of the formwork beams are arranged essentially in line, i.e. collinear, and longitudinal displacement of the connected formwork beams is blocked against each other. The formwork supports can thus be releasably connected to one another at the end faces in order to effect a transmission of force along the formwork supports. The stability of the ceiling formwork can advantageously be increased significantly in this way. It is particularly advantageous that a continuous beam effect is achieved which can be taken into account for the necessary load-bearing capacity of the ceiling props. This means that the number of formwork props can be reduced. Furthermore, it is not necessary to provide a lateral offset between the successive formwork supports in order to create an overlap area at the end areas. It is also advantageous that it is not necessary to place the connected formwork supports under the longitudinal connection. In a preferred embodiment, the coupling area between the two formwork supports is therefore free from being placed under a formwork prop. The first connecting strap is mounted on the first end of the formwork support, ie attached to the first end of the formwork support via a fastening device. Advantageously the first connecting strap is designed as an adapter, which in particular can also be attached to conventional formwork supports.

Für die Zwecke dieser Offenbarung beziehen sich die Orts- und Richtungsangaben, wie "horizontal", "vertikal", "oben", "unten", auf einen horizontalen Gebrauchszustand des Schalungsträgers. "Lösbar" bedeutet, dass eine 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", "top", "bottom", refer to a horizontal state of use of the formwork support. “Detachable” means that a connection can be established and released several times, preferably without tools, without significant loss of functionality.

Bevorzugt weisen der untere Gurt und der obere Gurt jeweils eine Breite (d.h. horizontale Erstreckung) von 50 mm bis 100 mm, insbesondere im Wesentlichen 80 mm, auf. Der Steg weist bevorzugt eine Höhe (d.h. vertikale Erstreckung) zwischen den Innenseiten des oberen und unteren Gurts von 50 mm bis 200 mm, insbesondere im Wesentlichen 120 mm, auf. Die Gesamthöhe des Schalungsträgers beträgt bei einer bevorzugten Ausführungsform im Wesentlichen 200 mm bei einer Breite des oberen und unteren Gurtelements von im Wesentlichen 80 mm. Der obere Gurt, der untere Gurt und der Steg sind bevorzugt jeweils überwiegend aus einem Holzwerkstoff gebildet. An den Enden des Schalungsträgers können Schutzkappen, insbesondere aus Kunststoff, vorgesehen sein.The lower belt and the upper belt preferably each have a width (i.e. horizontal extension) of 50 mm to 100 mm, in particular essentially 80 mm. The web preferably has a height (i.e. vertical extent) between the inner sides of the upper and lower belts of 50 mm to 200 mm, in particular substantially 120 mm. In a preferred embodiment, the total height of the formwork support is essentially 200 mm with a width of the upper and lower chord elements of essentially 80 mm. The upper belt, the lower belt and the web are preferably each formed predominantly from a wood material. Protective caps, in particular made of plastic, can be provided at the ends of the formwork support.

Gemäß einer bevorzugten Ausführungsform ist am zweiten Ende des Schalungsträgers eine zweite Verbindungslasche mit einem zweiten Kopplungsteil zur lösbaren Längsverbindung mit einem ersten Kopplungsteil des weiteren Schalungsträgers montiert. Somit sind die Verbindungslaschen an den beiden gegenüberliegenden Längsenden des Schalungsträgers vorgesehen. Die zweite Verbindungslasche mit dem zweiten Kopplungsteil ist für eine Längsverbindung mit der ersten Verbindungslasche des weiteren Längsträgers eingerichtet, welche ident zur ersten Verbindungslasche des Schalungsträgers ist. Vorzugsweise unterscheiden sich das erste und das zweite Kopplungsteil voneinander, um eine einfache Verbindung der Schalungsträger zu ermöglichen. So ist es günstig, wenn das erste Kopplungsteil als Einhängeglied und das zweite Kopplungsteil als Aufnahmeglied ausgebildet ist. Bei dieser Ausführungsvariante wird das erste Kopplungsteil von oben in das zweite Kopplungsteil eingehängt.According to a preferred embodiment, a second connecting strap with a second coupling part for a detachable longitudinal connection with a first coupling part of the further formwork support is mounted on the second end of the formwork support. Thus, the connecting straps are provided on the two opposite longitudinal ends of the formwork support. The second connecting strap with the second coupling part is set up for a longitudinal connection with the first connecting strap of the further longitudinal girder, which is identical to the first connecting strap of the formwork girder. The first and the second coupling part preferably differ from one another in order to enable a simple connection of the formwork supports. It is therefore advantageous if the first coupling part is designed as a suspension element and the second coupling part as a receiving element. In this embodiment, the first coupling part is hooked into the second coupling part from above.

Die erste und die zweite Verbindungslasche sind bevorzugt aus Metall, vorzugsweise Stahl oder Aluminium, oder aus einem Kunststoff gefertigt.The first and second connecting tabs are preferably made of metal, preferably steel or aluminum, or of a plastic.

Gemäß einer bevorzugten Ausführungsform ist als erstes Kopplungsteil ein Bolzen und/oder als zweites Kopplungsteil eine Bolzenaufnahme vorgesehen. Die Bolzenaufnahme weist einen nach oben offenen Querschnitt auf, so dass der Bolzen von oben in die Bolzenaufnahme eingefügt werden kann.According to a preferred embodiment, a bolt is provided as the first coupling part and / or a bolt receptacle is provided as the second coupling part. The bolt receptacle has a cross-section that is open at the top, so that the bolt can be inserted into the bolt receptacle from above.

Gemäß einer bevorzugten Ausführungsform weist die zweite Verbindungslasche oberhalb der Bolzenaufnahme ein Rückhalteelement zur Aushubsicherung auf. Das Rückhalteelement oberhalb, d.h. in einem vertikalen Abstand zur Bolzenaufnahme, verhindert, dass der Schalungsträger von der horizontalen Gebrauchsstellung versehentlich vertikal nach oben ausgehoben werden kann. Bei der Demontage wird der Schalungsträger herunter geschwenkt, wobei das Rückhalteelement in der heruntergeschwenkten Stellung des Schalungsträgers nicht wirksam ist, um die Abnahme des Schalungsträgers zu ermöglichen.According to a preferred embodiment, the second connecting strap has a retaining element above the bolt receptacle for securing against excavation. The retaining element above, i.e. at a vertical distance from the bolt receptacle, prevents the formwork carrier from being accidentally lifted vertically upwards from the horizontal position of use. During dismantling, the formwork carrier is pivoted down, the retaining element not being effective in the pivoted down position of the formwork carrier in order to enable the formwork carrier to be removed.

Hinsichtlich einer konstruktiv einfachen, zuverlässigen Ausführung ist es günstig, wenn als Rückhalteelement ein Plattenteil vorgesehen ist.With regard to a structurally simple, reliable design, it is advantageous if a plate part is provided as the retaining element.

In einer Ausführungsvariante ist das Rückhalteelement beweglich an der ersten Verbindungslasche angeordnet, um von einer Wirkstellung in eine Demontagestellung überführt zu werden. In der Wirkstellung verhindert das Rückhalteelement, dass der Schalungsträger von der horizontalen Gebrauchsstellung vertikal nach oben abgehoben werden kann. In der Demontagestellung erlaubt das Rückhalteelement die Abnahme des Schalungsträgers aus der horizontalen Gebrauchsstellung heraus.In a variant embodiment, the retaining element is movably arranged on the first connecting strap in order to be transferred from an operative position into a dismantling position. In the active position, the retaining element prevents the formwork carrier from being lifted vertically upwards from the horizontal position of use. In the dismantling position, the retaining element allows the formwork support to be removed from the horizontal position of use.

Um die Verbindung des Schalungsträgers mit dem weiteren Schalungsträger zu erleichtern, weist die zweite Verbindungslasche bei einer bevorzugten Ausführungsform ein Führungselement auf, welches von dem zweiten Kopplungsteil, insbesondere von der Bolzenaufnahme, nach oben, insbesondere schräg nach oben, absteht.In order to facilitate the connection of the formwork support to the further formwork support, in a preferred embodiment the second connection tab has a guide element which protrudes upwards, in particular obliquely upwards, from the second coupling part, in particular from the bolt receptacle.

Zur Ableitung von Lasten im Gebrauch des Schalungsträgers ist es günstig, wenn die erste und/oder zweite Verbindungslasche einen an der Innenseite des oberen Gurts anliegenden oberen Stützteil und/oder einen an der Innenseite des unteren Gurts anliegenden unteren Stützteil aufweist.To divert loads when the formwork beam is in use, it is advantageous if the first and / or second connecting tab has an upper support part resting on the inside of the upper strap and / or a lower support part resting on the inside of the lower strap.

Zur Nachrüstung bestehender Schalungsträger ist es vorteilhaft, wenn die erste Verbindungslasche je einen Befestigungsschenkel an gegenüberliegenden Längsseiten des Stegs aufweist. Bevorzugt sind der erste und der zweite Befestigungsschenkel als Befestigungsplatten ausgeführt, welche im Wesentlichen parallel zum Steg angeordnet sind. Somit wird eine stabile Befestigung der ersten Verbindungslasche am Schalungsträger ermöglicht. Bevorzugt steht der erste und zweite Befestigungsschenkel jeweils seitlich nicht über den oberen und unteren Gurt des Schalungsträgers hinaus. Die zweite Verbindungslasche weist bevorzugt ebenfalls einen ersten und einen zweiten Befestigungsschenkel auf, so dass auf die vorstehenden Erläuterungen verwiesen werden kann.To retrofit existing formwork supports, it is advantageous if the first connecting strap has a respective fastening leg on opposite longitudinal sides of the web. The first and second fastening legs are preferably designed as fastening plates which are arranged essentially parallel to the web. This enables stable fastening of the first connecting strap on the formwork support. The first and second fastening legs preferably do not protrude laterally beyond the upper and lower chords of the formwork support. The second connecting strap preferably also has a first and a second fastening leg, so that reference can be made to the explanations given above.

Um herkömmliche Schalungsträger mit der ersten Verbindungslasche auszustatten, ist es günstig, wenn der Steg zumindest eine Durchgangsöffnung am ersten Ende aufweist, durch welche ein Befestigungselement, insbesondere eine Schraube, der ersten Verbindungslasche geführt ist. Ein besonderer Vorteil dieser Ausführungsform liegt darin, dass viele Schalungsträger bereits eine solche Durchgangsöffnung (z.B. für die Anbringung eines Krangehänges oder eines Seitenschutzadapters) aufweisen, welche somit für die Nachrüstung der ersten Verbindungslasche genutzt werden kann. Bevorzugt ist die Schraube im Wesentlichen senkrecht zur Hauptebene des Stegs zwischen dem oberen Gurt und dem unteren Gurt angeordnet. Besonders bevorzugt ist es, wenn zwei Durchgangsöffnungen in Längsabstand zueinander vorgesehen sind, welche jeweils ein Befestigungselement, insbesondere eine Schraube, aufnehmen. Die zweite Verbindungslasche kann über zumindest ein weiteres Befestigungselement an zumindest einer weiteren Durchgangsöffnung am zweiten Ende des Schalungsträgers befestigt werden.In order to equip conventional formwork supports with the first connecting strap, it is advantageous if the web has at least one through opening at the first end through which a fastening element, in particular a screw, of the first connecting strap is guided. A particular advantage of this embodiment is that many formwork supports already have such a through opening (eg for attaching a crane suspension or a side protection adapter), which can thus be used for retrofitting the first connecting bracket. The screw is preferably arranged essentially perpendicular to the main plane of the web between the upper strap and the lower strap. It is particularly preferred if two through openings are provided at a longitudinal distance from one another and each receive a fastening element, in particular a screw. The second connecting strap can be attached to at least one additional through opening at the second end of the formwork support via at least one additional attachment element.

Beim Aufbau einer Deckenschalung werden zwei Schalungsträger in der zuvor beschriebenen Ausführung lösbar miteinander verbunden. Zu diesem Zweck wird die erste Verbindungslasche des Schalungsträgers mit der zweiten Verbindungslasche des weiteren Schalungsträgers in Eingriff gebracht, so dass der Schalungsträger und der weitere Schalungsträger gegen ein Auseinanderziehen in Längsrichtung gesichert sind. Im verbundenen Gebrauchszustand sind die Längsachsen des Schalungsträgers und des weiteren Schalungsträgers im Wesentlichen fluchtend in derselben Horizontalebene, d.h. kollinear, angeordnet. Bevorzugt sind die Schalungsträger im Gebrauchszustand durch mehrere Schalungsstützen abgestützt.When building a ceiling formwork, two formwork supports are releasably connected to one another in the design described above. For this purpose, the first connecting tab of the formwork carrier is brought into engagement with the second connecting tab of the further formwork carrier so that the formwork carrier and the further formwork carrier are secured against being pulled apart in the longitudinal direction. In the connected state of use, the longitudinal axes of the formwork beam and the further formwork beam are essentially aligned in the same horizontal plane, i.e. collinear, arranged. The formwork supports are preferably supported by several formwork supports when in use.

Beim Aufbau der Deckenschalung kann zum Beispiel zuerst der weitere Schalungsträger in der im Wesentlichen horizontalen Gebrauchsstellung angeordnet werden, in welcher der weitere Schalungsträger mit mindestens einer Schalungsstütze unterstellt ist. Anschließend wird der Schalungsträger in einer schräg zur Vertikalen angeordneten Zwischenstellung mit dem weiteren Schalungsträger verbunden, danach in die horizontale Gebrauchsstellung aufgeschwenkt und mit einer weiteren Schalungsstütze unterstellt. Auf den direkt auf den Schalungsstützen abgestützten Schalungsträgern, den sogenannten Jochträgern, können anschließend mehrere Querträger, im Wesentlichen quer dazu angeordnet werden. Die Querträger können entsprechend den zuvor beschriebenen Schalungsträgern ausgebildet sein, jedoch kann auch eine herkömmliche Ausführung ohne erste bzw. zweite Verbindungslaschen verwendet werden. Dieser Vorgang wird abhängig von der Dimension der Deckenschalung entsprechend oft wiederholt. Schließlich werden eine Anzahl von Schalungsplatten auf den Querträgern positioniert, so dass eine Deckenschalung zum Betonieren eines Deckenelements zur Verfügung steht.When assembling the ceiling formwork, for example, the further formwork carrier can first be arranged in the essentially horizontal position of use, in which the further formwork carrier is supported with at least one formwork support. The formwork support is then connected to the further formwork support in an intermediate position arranged obliquely to the vertical, then pivoted into the horizontal position of use and placed under it with a further formwork support. On the formwork girders, the so-called yoke girders, which are directly supported on the formwork supports, several cross girders can then be arranged, essentially at right angles to them. The cross beams can be designed in accordance with the formwork beams described above, but a conventional design without first or second connecting straps can also be used. This process is repeated as often as necessary, depending on the size of the slab formwork. Finally, a number of formwork panels are positioned on the cross members, so that a ceiling formwork is available for concreting a ceiling element.

Als Schalungsstützen sind bevorzugt Teleskopstützen jeweils mit einem unteren Stützenteil und einem oberen Stützenteil vorgesehen. Aufgrund der Längsverbindung zwischen den Schalungsträgern können zumindest einzelne Schalungsstützen, insbesondere zwischen den Randbereichen der Deckenschalung, frei von vom unteren Stützenteil abstehenden Stützbeinen sein.Telescopic supports each with a lower support part and an upper support part are preferably provided as formwork supports. Due to the longitudinal connection between the formwork supports, at least individual formwork props, in particular between the edge regions of the ceiling formwork, can be free of support legs protruding from the lower prop part.

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. Fig. 1 shows a ceiling formwork 1 with telescopic formwork props 2, which, as usual, each have a lower prop part 3 in the form of an outer tube and an upper prop part 4 displaceable therein in the form of an inner tube. The length of the telescopic formwork prop 2 is adjusted by means of a locking element 5. To fine-tune the length of the formwork prop 2, a nut is provided which is screwed onto an external thread of the lower prop part 3. The formwork props 2 have at the upper ends of the upper prop part 4 holding or support heads 6, on which formwork supports 7 are supported. On the upper sides of the formwork girders 7, transverse girders 8 are arranged, essentially perpendicular thereto, on which in turn formwork panels 9 are placed. The tops of the shuttering panels 9 form the shuttering skin on which a concrete ceiling element (or a floor element) is poured. For the sake of clarity, in Fig. 1 not all cross members 8 and formwork panels 9 are shown. In the embodiment shown, the formwork props 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 props 2 in the interior of the ceiling formwork 1 between the side edges of the ceiling formwork 1 are free of such support legs 10, so that the formwork props 2 are only supported on the floor surface 11 via foot plates 12 at the lower ends of the lower prop parts 3. 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 FIGS. 2 to 4 As can be seen, the formwork supports 7 each have an upper belt 13, a lower belt 14 and a web 15 connecting the upper belt 13 to the lower belt 14, so that the formwork supports 7 are I-shaped in cross section (perpendicular to the longitudinal axis). The upper belt 13, the lower belt 14 and the web 15 are in the embodiment shown each mainly formed from a wood material. At the ends of the formwork support 7, protective caps 16 made of plastic are provided. At the first end of the formwork support 7 there is also a first connection strap 17 with a first coupling part 18 and at the second end of the formwork support 7 a second connection strap 19 with a second coupling part 20 is mounted. The first and second connection tabs 19 are made of metal, preferably steel or aluminum, or 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 FIGS. 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 with one another. A bolt 21 is provided as the first coupling part 18, and a bolt receptacle 22 in the form of an upwardly open recess is provided as the second coupling part 20. The second connecting strap 19 also has a guide element 23 which protrudes obliquely upward from the second coupling part 20, here the bolt receptacle 20, in order to facilitate the hooking 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 strikes the retaining element 24 when it is lifted vertically. As a result, the formwork support 7 is secured against excavation. In the embodiment shown, a plate part is provided as the retaining element 24, 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 FIGS. 5 and 6 Furthermore, the first connecting tab 17 and the second connecting tab 19 each have an upper support part 25 in contact with the inside 13a (ie with the side facing away from the shuttering panel 9) of the upper belt 13 and a lower support part 26 in contact with the inside 14a (ie with the side facing away from the formwork prop 2) of the lower strap 14 of the formwork support 7. A favorable load transfer is thus achieved in the connected state of the formwork supports 7.

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 from Figures 9 and 10 As can be seen, the first connecting tab 17 and the second connecting tab 19 each have a fastening leg 27 on the opposite longitudinal sides 15 a of the web 15. The fastening legs 27 are pushed onto the web 15 in such a way that the first coupling element 18 is arranged in front of the first end face of the I-shaped longitudinal section of the formwork support 7 and the second coupling element 20 is arranged in front of the second end face of the I-shaped longitudinal section of the formwork support 7. At the first and second end, the web 15 of the formwork support 7 each has at least one through opening 28, here two through openings 28 at longitudinal distances from one another, which in the assembled state are aligned with fastening openings 29 of the first connecting strap 17 and the second connecting strap 19, respectively, around the arrangement of fastening elements 30, here screws, to enable.

In den Fig. 11 bis Fig. 13 ist die Auflagerung des Schalungsträgers 7 auf dem Haltekopf 6 der Schalungsstütze 7 im Detail gezeigt. In der gezeigten Ausführung weist der Haltekopf 6 ein erstes Anschlusselement 31 auf, welches für eine lösbare Verbindung mit einem zweiten Anschlusselement 32 am ersten Ende einer Querstange 33 eingerichtet ist. Im verbundenen Zustand steht die Querstange 33 in einer horizontaler Ebene im Wesentlichen senkrecht zu dem Schalungsträger 7 vom Haltekopf 6 ab. Am zweiten Ende der Querstange 33 ist ein entsprechendes zweites Anschlusselement 32 vorgesehen, welches in das entsprechende erste Anschlusselement 31 des Haltekopfs 6 der benachbarten Schalungsstütze 2 eingehängt ist (vgl. Fig. 1). In der gezeigten Ausführung weist der Haltekopf 6 einen Grundkörper 34 aus Metall auf, an welchem das erste Anschlusselement 31 für die Querstange 33 und zwei hakenförmige Umgreifelemente 35 - welche im Zusammenhang mit Fig. 17ff. näher erläutert werden - einteilig ausgebildet sind.In the FIGS. 11 to 13 the support of the formwork support 7 on the holding head 6 of the formwork prop 7 is shown in detail. In the embodiment shown, the holding head 6 has a first connection element 31, which is set up for a detachable connection to a second connection element 32 at the first end of a transverse rod 33. In the connected state, the transverse rod 33 projects in a horizontal plane essentially perpendicular to the formwork support 7 from the holding head 6. At the second end of the crossbar 33, a corresponding second connection element 32 is provided, which is hooked into the corresponding first connection element 31 of the holding head 6 of the adjacent formwork prop 2 (cf. Fig. 1 ). In the embodiment shown, the holding head 6 has a base body 34 made of metal, on which the first connection element 31 for the crossbar 33 and two hook-shaped encompassing elements 35 - which are in connection with Fig. 17ff . are explained in more detail - are formed in one piece.
