Description

Technisches GebietTechnical area

Die Erfindung betrifft einen Schalungsträger mit mindestens einer nagelbaren Leiste, mit mindestens einem Befestigungsmittel und mit einem metallischen Hohlprofil, das mehrere Seitenwände aufweist und das mit seinen Profilschenkeln eine Längsnut ausbildet, welche Längsnut in mindestens einer ihrer Nutwände wenigstens eine Nutwandöffnung aufweist, wobei die in der Längsnut vorgesehene Leiste durch das die Nutwandöffnung durchragende lösbare Befestigungsmittel am Hohlprofil befestigt ist.The invention relates to a formwork support with at least one nailable strip, with at least one fastening means and with a metallic hollow profile having a plurality of side walls and forms with its profile limbs a longitudinal groove, which longitudinal groove in at least one of its groove walls has at least one groove wall opening, wherein in the Longitudinal groove provided strip is secured by the groove wall opening projecting through releasable fastening means on the hollow profile.

Stand der TechnikState of the art

Um einen Schalungsträger mit einem metallischen Hohlprofil, beispielsweise aus einem verzinkten Stahl- oder Aluminiumblech, für Schalungen im Bauwesen nagelbar auszustatten, ist aus dem Stand der Technik bekannt ( EP0279049A2 ), eine nagelbare Leiste in eine Längsnut des Hohlprofils einzusetzen und darin zu befestigen. Letzteres wird mithilfe von Befestigungsmittel, die durch eine Nutwandöffnung der Nutwand der Längsnut in die Leiste eingetrieben sind, bewerkstelligt, wobei die Längsnut von Profilschenkeln des Hohlprofils ausgebildet wird. Nachteilig muss bei Verwendung derartiger Schalungsträger mit einer erheblichen Verschmutzung über seinen gesamten Querschnitt gerechnet werden, was beispielsweise von einer hydraulisch härtbaren Zusammensetzung herrühren kann, die Stoßlücken zwischen den Schalungsträgern durchfließt. Mit festsitzenden Befestigungsmitteln am Hohlprofil ist somit zu rechnen - was eine Wartung der nagelbaren Leiste am Schalungsträger erschwert bzw. behindert und zu Beschädigungen am Hohlprofil führen kann. Von einer verminderten Standfestigkeit des Schalungsträgers ist somit auszugehen.In order to provide a formwork support with a metallic hollow profile, for example from a galvanized steel or aluminum sheet, nailable for formwork in construction, is known from the prior art ( EP0279049A2 ), to insert a nailable strip in a longitudinal groove of the hollow profile and secure it therein. The latter is accomplished by means of fastening means which are driven by a groove wall opening of the groove wall of the longitudinal groove in the strip, wherein the longitudinal groove of profile legs of the hollow profile is formed. A disadvantage must be expected when using such formwork beams with a significant contamination over its entire cross-section, which may for example be due to a hydraulically curable composition that flows through impact gaps between the formwork beams. With fixed fasteners on the hollow profile is therefore to be expected - which makes maintenance of the nailable bar on the formwork carrier difficult or hindered and can lead to damage to the hollow profile. From a reduced stability of the formwork support is therefore assumed.

US 6 189 854 B1 offenbart die Merkmale des Oberbegriffs des Anspruchs 1. US Pat. No. 6,189,854 B1 discloses the features of the preamble of claim 1.

Darstellung der ErfindungPresentation of the invention

Die Erfindung hat sich daher die Aufgabe gestellt, einen eingangs geschilderten Schalungsträger mit einem metallischen Hohlprofil derart konstruktiv zu verbessern, dass dieser selbst widrigen Einflüssen trotzen und damit eine hohe Standfestigkeit aufweisen kann. Zudem soll der Schalungsträger eine vergleichsweise hohe Formstabilität aufweisen.The invention is therefore based on the object to improve an initially described formwork support with a metallic hollow profile in such a constructive way that this defy even adverse influences and thus can have a high stability. In addition, the formwork support should have a comparatively high dimensional stability.

Die Erfindung löst die gestellte Aufgabe durch die Merkmale des Anspruchs 1. Ist das Hohlprofil geschlossen ausgebildet und bildet es an einer ersten Seitenwand durch deren Profilschenkel die Längsnut aus, kann zunächst eine formstabile Aufnahme für eine nagelbare Leiste geschaffen werden, die selbst hohe mechanische Schlagbelastungen verformungsfrei aufnehmen und damit sicher abtragen kann. Ist zudem wenigstens eine an diese erste Seitenwand geneigt anschließende weitere Seitenwand auf Höhe der Nutwandöffnung der Längsnut ausgenommen, um eine Zugangsöffnung für das lösbare Befestigungsmittel auszubilden, so kann sich die Möglichkeit eröffnen, die Befestigungsmittel, insbesondere deren Betätigungselemente, vor Widrigkeiten bei der Verwendung des Schalungsträgers zu schützen. Die geneigt anschließende Seitenwand kann nämlich eine eventuell über den Schalungsträger fließende hydraulisch härtbare Zusammensetzung, beispielsweise Beton, vom Befestigungsmittel wegführen bzw. wegleiten, sodass die Befestigungsmittel stets frei von Verschmutzung bleiben - und damit deren Lösbarkeit nicht erschwert oder verhindert wird.
Dies kann nicht nur die Wartung des Schalungsträgers im Bereich der nagelbaren Leiste erleichtern, sondern auch das Hohlprofil frei von Beschädigungen halten, wenn es gilt, das Befestigungsmittel unter Benützung der Betätigungselemente zu entfernen - beispielsweise um eine verschlissene nagelbare Leiste vom Schalungsträger zu entfernen. Dies kann auch vergleichsweise handhabungsfreundlich sein, weil aufgrund der Zugangsöffnung das lösbare Befestigungsmittel betätigt werden kann bzw. diese Zugangsöffnung für das Betätigen des lösbaren Befestigungsmittels ausgebildet ist. Der erfindungsgemäße Schalungsträger kann somit eine hohe Standzeit und auch eine erleichterte Wartung bzw. Verwendung gewährleisten.The invention achieves the stated object by the features of claim 1. If the hollow profile formed closed and forms it on a first side wall by the profile leg of the longitudinal groove, first a dimensionally stable receptacle for a nailable bar can be created, the deformation even high mechanical impact loads record and thus can safely ablate. If, in addition, at least one additional sidewall adjoining this first side wall is recessed at the level of the groove wall opening of the longitudinal groove in order to form an access opening for the releasable fastening means, then the possibility of opening the fastening means, in particular their actuating elements, against adversities when using the formwork support to protect. Namely, the inclined adjoining side wall can lead away or guide away any hydraulically curable composition, for example concrete, flowing over the formwork support, away from the fastening means, so that the fastening means always remain free from contamination - and thus their solubility is not impeded or prevented.
This can not only facilitate the maintenance of the formwork support in the area of the nailable bar, but also keep the hollow profile free of damage when it comes to remove the fastener using the actuators - for example, to remove a worn nailable bar from the formwork support. This can also be comparatively easy to handle, because due to the access opening, the releasable fastening means can be actuated or this access opening is designed for actuating the releasable fastening means. The formwork support according to the invention can thus ensure a long service life and also easier maintenance or use.

Die Montage und/oder Wartung des Schalungsträgers kann sich weiter vereinfachen, wenn die Zugangsöffnung in ihrem Durchmesser größer als die Nutwandöffnung ist. Dabei kann das Befestigungsmittel von der Außenseite her durch die Zugangsöffnung in Richtung der Nutwandöffnung einfacher geführt werden, um die nagelbare Leiste am Schalungsträger zu befestigen. Als besonders vorteilhaft kann sich hierbei herausstellen, wenn die Größe der Zugangsöffnung derart gewählt ist, dass das zum Befestigungsmittel zugehörige Werkzeug mit dem Befestigungsmittel durch die Durchgangsöffnung geführt werden kann, um das Befestigungsmittel in die nagelbarer Leiste einzutreiben.The installation and / or maintenance of the formwork support can be further simplified if the access opening in its diameter is greater than the groove wall opening. In this case, the fastening means can be guided from the outside through the access opening in the direction of the groove wall opening easier to attach the nailable bar on the formwork support. In this case, it may turn out to be particularly advantageous if the size of the access opening is selected such that the tool associated with the fastening means can be guided through the passage opening with the fastening means in order to drive the fastening means into the nailable strip.

Sind die Zugangsöffnung und die Nutwandöffnung fluchtend zueinander angeordnet, kann dies die Montage und Wartung des Schalungsträgers weiter erleichtern. Insbesondere kann damit die Werkzeugzugänglichkeit zur Nutwandöffnung erleichtert werden.If the access opening and the groove wall opening are arranged in alignment with one another, this can further facilitate the assembly and maintenance of the formwork support. In particular, the tool accessibility to the groove wall opening can thus be facilitated.

Weisen die Nutwand und mindestens eine an die erste Seitenwand anschließende Seitenwand je eine Lochreihe an Nutwandöffnungen bzw. Zugangsöffnungen auf, kann die Befestigung der nagelbaren Leiste in regelmäßigen Abständen erfolgen - und somit eine standfestere Verbindung geschaffen werden.If the groove wall and at least one side wall adjoining the first side wall each have a row of holes at groove wall openings or access openings, the nailable strip can be fastened at regular intervals - and thus a more stable connection can be created.

Eine beidseitige Befestigung der nagelbaren Leiste am Schalungsträger kann ermöglicht werden, wenn an beiden Nutwänden der Längsnut je wenigstens eine Nutwandöffnung für Befestigungsmittel vorgesehen sind, wobei die beiden an die erste Seitewand anschließenden Seitenwände je auf Höhe der jeweiligen Nutwandöffnung eine Zugangsöffnung für das jeweilige lösbare Befestigungsmittel ausbilden. Vorzugsweise können die gegenüberliegenden, lösbare Befestigungsmittel gegeneinander in Längsrichtung des Schalungsträgers versetzt angeordnet sein.A two-sided attachment of the nailable bar on the formwork support can be made possible if at least one groove wall opening for fastening means are provided on both groove walls of the longitudinal groove, wherein the two adjoining the first side wall side walls each at the level of the respective groove wall opening form an access opening for the respective releasable fastening means , Preferably, the opposing, releasable fastening means can be arranged offset from each other in the longitudinal direction of the formwork support.

Die an die erste Seitenwand anschließende Seitenwand verläuft zur Nutwand beabstandet, somit wird der Kopf der Befestigungsmittel im Hohlprofil verdeckt angeordnet. Hierbei kann es bereits ausreichen, dass diese an die erste Seitenwand anschließende weitere Seitenwand auf Höhe der Nutwandöffnung der Längsnut beabstandet verläuft. Dies kann die Gefahr von Verunreinigung am Befestigungsmittel durch eine herabfließende hydraulisch härtbare Zusammensetzung weiter reduzieren. Durch diese vergleichsweise einfache Konstruktion können nämlich die Betätigungselemente, beispielsweise ein Schraubenkopf, am Befestigungsmittel, beispielsweise einer Schraube, vom Hohlprofil aufgenommen und damit geschützt oder auch frei von Verschmutzung bleiben. Die Standfestigkeit des Schalungsträgers noch weiter erhöht. Einfache Konstruktionsverhältnisse können sich ergeben, wenn die Seitenwand zur Nutwand parallel versetzt verläuft.The adjoining the first side wall side wall extends to the groove wall spaced, thus the head of the fastening means is arranged concealed in the hollow profile. It may already be sufficient for this further side wall, which adjoins the first side wall, to extend at the level of the groove wall opening of the longitudinal groove. This can further reduce the risk of contamination to the fastener by a downwardly flowing hydraulically settable composition. By virtue of this comparatively simple construction, the actuating elements, for example a screw head, on the fastening means, for example a screw, can be received by the hollow profile and thus protected or remain free from contamination. The stability of the formwork support is further increased. Simple construction conditions can result if the side wall is offset parallel to the groove wall.

Das Hohlprofil weist einen rechteckförmigen Querschnitt auf, dessen Schmalseite die erste Seitenwand ausbildet. Somit werden die Formstabilität und damit die Standfestigkeit des Schalungsträgers weiter verbessert. Vorzugsweise können hierfür die erste und die jeweilige an die erste Seitenwand anschließende Seitenwand rechtwinkelig zueinander verlaufend angeordnet sein, um eine vergleichsweise hohe Formstabilität am Schalungsträger zu ermöglichen. Zudem kann sich damit die Handhabbarkeit des Schalungsträgers erleichtern, weil durch diese erfindungsgemäße konstruktive Ausbildung die Stapelbarkeit und damit auch die Transportsicherheit erhöht werden kann.The hollow profile has a rectangular cross-section, the narrow side of which forms the first side wall. Thus, the dimensional stability and thus the stability of the formwork support are further improved. Preferably, for this purpose, the first and the respective adjoining the first side wall side wall may be arranged perpendicular to each other to allow a relatively high dimensional stability on the formwork support. In addition, this can facilitate the handling of the formwork support, because the stackability and thus the transport safety can be increased by this constructive design according to the invention.

Die Montage hinsichtlich des Befestigungsmittels kann erleichtert werden, wenn das lösbare Befestigungsmittel als selbstschneidende Schraube mit einem Mehrkantkopf ausgeführt ist. Zudem kann durch die Ausführung des Schraubenkopfs eine Abscheren der Schraube ermöglicht werden, wodurch die Leiste selbst bei festsitzender Schraube gewartet werden kann.The mounting with respect to the fastening means can be facilitated if the releasable fastening means is designed as a self-tapping screw with a polygonal head. In addition, by the execution of the screw head, a shearing of the screw can be made possible, whereby the bar can be maintained even with stuck screw.

Weist die an die erste Seitenwand anschließende Seitenwand unterhalb der Zugangsöffnung eine Längssicke auf, kann eine Grifffläche zur leichteren Handhabung des Schalungsträgers geschaffen werden. Zudem kann damit die Formstabilität des Schalungsträgers weiter erhöht werden. Die Handhabung des Schalungsträgers kann weiter verbessert werden, wenn die Längssicke halbrund ausgebildet ist - da sie damit unter anderem leichter gegriffen werden kann.If the side wall adjoining the first side wall has a longitudinal bead below the access opening, a gripping surface for easier handling of the formwork support can be created. In addition, thus the dimensional stability of the formwork support can be further increased. The handling of the formwork support can be further improved if the longitudinal bead is formed semicircular - because it can be used so that among other things easier.

Weist mindestens eine, an die erste Seitenwand anschließende Seitenwand, insbesondere mittig, eine Lochreihe mit einem nach innen gebogenen Öffnungsrand auf, so kann dies zu einer weiteren Erhöhung der Formstabilität des Schalungsträgers und gleichzeitig zu einer Gewichtseinsparung am Schalungsträger führen - insbesondere, wenn die Lochreihe mittig angeordnet ist. Vorzugsweise kann diese Lochreihe an beiden angrenzenden Seitenwänden vorgesehen und in Flucht angeordnet sein.If at least one side wall adjoining the first side wall, in particular in the middle, has a row of holes with an inwardly curved opening edge, this can lead to a further increase in dimensional stability of the formwork support and at the same time a weight saving on the formwork support - in particular if the row of holes is centered is arranged. Preferably, this row of holes can be provided on both adjacent side walls and arranged in alignment.

Ein Austauschen der nagelbaren Leiste kann dadurch erleichtert werden, indem die Profilschenkel der ersten Seitenwand eine hinterschneidungsfreie Längsnut ausbilden. Bei entfernten Befestigungsmitteln kann die Leiste dann nämlich auf einfache Weise aus der Längsnut abgehoben werden.Replacing the nailable strip can be facilitated by the profile legs of the first side wall form a undercut-free longitudinal groove. In remote fasteners, the strip can then be lifted in a simple manner from the longitudinal groove.

Verläuft die in der Längsnut vorgesehene nagelbare Leiste plan mit der ersten Seitenwand, kann die Leiste zur Vergrößerung der Auflagefläche am Schalungsträger beitragen - und damit die Abstützung der Betonschalelemente verbessern.If the nailable strip provided in the longitudinal groove runs flush with the first side wall, the strip can contribute to increasing the contact surface on the formwork support - and thus improve the support of the concrete formwork elements.

Ist die Längsnut mittig an der ersten Seitenwand vorgesehen, kann dies der Formstabilität des Schalungsträgers dienlich sein. Vergleichsweise hohe Belastungen beim Nageln der Leiste können nämlich damit symmetrisch in den Schalungsträger eingeleitet werden.If the longitudinal groove is provided centrally on the first side wall, this can serve the dimensional stability of the formwork support. Comparatively high loads when nailing the strip can namely be introduced symmetrically into the formwork support.

Der Schalungsträger selbst kann verhältnismäßig einfach an einer Unterkonstruktion befestigt werden, wenn dieser mit seiner dritten Seitenwand, die der ersten Seitenwand gegenüberliegt, eine T-förmige Nut für Verbindungsmittel ausbildet.The formwork support itself can be attached relatively easily to a substructure if it forms with its third side wall, which is opposite to the first side wall, a T-shaped groove for connecting means.

Der erfindungsgemäße Schalungsträger kann vorzugsweise bei einer Betonschalung mit einem Schalungselement verwendet werden, indem dieser auf der Rückseite des Schalungselements vorgesehenen wird, wobei das Schalungselement an der Leiste des Schalungsträgers befestigt, insbesondere mit dieser vernagelt, ist.The formwork support according to the invention may preferably be used in a concrete formwork with a formwork element by this is provided on the back of the formwork element, wherein the formwork element attached to the bar of the formwork support, in particular with this nailed is.

Weg zur Ausführung der ErfindungWay to carry out the invention

Gemäß den Figuren 1 und 2 wird beispielsweise ein Schalungsträger 1 zu einer teilweise dargestellten Betonschalung 100 gezeigt. Dieser Schalungsträger 1 weist eine nagelbare Leiste 2, beispielsweise Holzleiste, auf, die über mehrere Befestigungsmittel 3 mit dem metallischen Hohlprofil 4 des Schalungsträgers 1 verbunden ist. Und zwar ist auf der ersten Seitenwand 5 des Hohlprofils 4 eine Längsnut 6 vorgesehen, in die die nagelbare Leiste 2 eingesetzt ist. Diese Längsnut 6 wird von Profilschenkeln 7 der ersten Seitenwand 5 ausgebildet. Die nagelbare Leiste ist in der Längsnut 6 befestigt - hierzu weisen die Nutwände 9 der Längsnut 6 mehrere Nutwandöffnungen 10 auf, durch welche die jeweiligen Befestigungsmittel 3 ragen. Die Leiste kann am Nutgrund 24 aufliegen, was nicht näher dargestellt worden ist.According to the FIGS. 1 and 2 For example, a formwork support 1 is shown to a concrete formwork 100 partially shown. This formwork support 1 has a nailable strip 2, for example, wooden strip, which is connected via a plurality of fastening means 3 with the metallic hollow section 4 of the formwork support 1. Namely, a longitudinal groove 6 is provided on the first side wall 5 of the hollow section 4, in which the nailable strip 2 is inserted. This longitudinal groove 6 is formed by profile legs 7 of the first side wall 5. The nailable bar is in the longitudinal groove 6 attached - this, the groove walls 9 of the longitudinal groove 6 a plurality of groove wall openings 10, through which the respective fastening means 3 protrude. The bar can rest on the groove base 24, which has not been shown in detail.

Um die Befestigungsmittel 3 gegenüber Verschmutzung zu schützen, ist das Hohlprofil 4 geschossen ausgeführt, wie dies in Fig. 2 erkannt werden kann. Die Längsnut 6 wird dazu von Profilschenkeln 7 der ersten Seitenwand 5 ausgebildet und ist daher mechanisch besonders stabil ausgeführt. Außerdem zeigt das geschlossene Hohlprofil 4 zwei an diese erste Seitenwand 5 geneigt anschließende Seitenwände 11, 16, womit die Befestigungsmittel 3 überdeckt bzw. im Wesentlichen vom Äußeren des Hohlprofils bzw. abgeschirmt sind. Um die Zugänglichkeit der Befestigungsmittel 3 nicht zu erschweren, sind diese Seitenwände 11, 16 in der Höhe der Nutwandöffnungen 10 ausgenommen und bildet dort Zugangsöffnungen 12 aus. Das in Fig. 2 dargestellte Befestigungsmittel 3 ist beispielsweise als selbstschneidend Schraube 13 mit Mehrkantkopf 23, insbesondere Sechskantkopf, als Betätigungselement am Befestigungsmittel 3. Die Schraube 13 kann beispielsweise als Holzschraube ausgeführt sein. Durch die dementsprechende Ausbildung der Zugangsöffnungen 12 bleiben die Betätigungselemente der Befestigungsmittel 3 zugänglich.In order to protect the fastening means 3 against contamination, the hollow profile 4 is executed shot, as shown in Fig. 2 can be recognized. The longitudinal groove 6 is formed to profile limbs 7 of the first side wall 5 and is therefore designed to be particularly mechanically stable. In addition, the closed hollow profile 4 shows two side walls 11, 16 adjoining this first side wall 5, with which the fastening means 3 are covered or substantially shielded from the outside of the hollow profile or respectively. In order not to complicate the accessibility of the fastening means 3, these side walls 11, 16 are excluded in the height of the groove wall openings 10 and forms access openings 12 there. This in Fig. 2 shown fastening means 3, for example, as a self-tapping screw 13 with polygonal head 23, in particular hexagonal head, as an actuating element on the fastening means 3. The screw 13 may be performed, for example, as a wood screw. Due to the corresponding design of the access openings 12, the actuators of the fastening means 3 remain accessible.

Wie in Fig. 2 gezeigt, weisen die Zugangsöffnungen 12 einen größeren Durchmesser als die Nutwandöffnungen 10 auf. Dadurch kann gewährleistet werden, dass die Befestigungsmittel 3 durch die Zugangsöffnungen 12 geführt werden können, was die Montage der nagelbaren Leiste 2 in der Längsnut 6 erleichtert. Vorzugsweise sind die Zugangsöffnungen 12 derart im Durchmesser ausgeführt, dass auch ein - nicht näher dargestelltes - Werkzeug zum Vorsehen der Befestigungsmittel 3 durch die Zugangsöffnungen 12 in das Hohlprofil eingeführt werden kann.As in Fig. 2 As shown, the access openings 12 have a larger diameter than the groove wall openings 10. This can ensure that the fastening means 3 can be guided through the access openings 12, which facilitates the mounting of the nailable strip 2 in the longitudinal groove 6. Preferably, the access openings 12 are made in such a diameter that even - not shown - - tool for providing the fasteners 3 can be inserted through the access openings 12 in the hollow profile.

In Fig. 2 kann weiter erkannt werden, dass die an diese erste Seitenwand 5 anschließende Seitenwände 11, 16 von der Nutwand 9 beabstandet sind - wobei diese parallel zueinander verlaufen. Die Längsnut 6 ist dabei mittig an der ersten Schmalseite 5 vorgesehen bzw. wird von dieser ersten Schmalseite 5 ausgebildet.In Fig. 2 can be further recognized that adjoining this first side wall 5 side walls 11, 16 are spaced from the groove wall 9 - wherein these parallel to each other. The longitudinal groove 6 is provided centrally on the first narrow side 5 or is formed by this first narrow side 5.

Wie insbesondere in Fig. 1 zu erkennen, weisen sowohl die Nutwand 9, als auch die an diese erste Seitenwand 5 anschließende Seitenwände 11, 16 jeweils zueinander fluchtende Lochreihen von Nutwandöffnungen 10 bzw. Zugangsöffnungen 12 auf. Dadurch kann je nach Bedarf die nagelbare Leiste 2 am Hohlprofil 4 fixiert werden.As in particular in Fig. 1 to recognize, both the groove wall 9, and the adjoining these first side wall 5 side walls 11, 16 respectively mutually aligned rows of groove wall openings 10 and access openings 12. As a result, the nailable strip 2 can be fixed to the hollow profile 4 as needed.

Wie in Fig. 2 weiter zu entnehmen, sind die erste Seitenwand 5 und die an die erste Seitenwand 5 anschließenden beiden Seitenwände 11, 16 rechtwinkelig zueinander angeordnet - sowie auf Abstand zur Längsnut 6 bzw. deren Nutwand 9, sodass die Befestigungsmittel 3 vom Hohlprofil 4 aufgenommen und damit geschützt werden.As in Fig. 2 can be seen further, the first side wall 5 and adjoining the first side wall 5, two side walls 11, 16 are arranged perpendicular to each other - and at a distance from the longitudinal groove 6 and its groove wall 9, so that the fastening means 3 are taken up by the hollow section 4 and thus protected ,

Das Hohlprofil 4 weist zudem einen rechteckförmigen Querschnitt auf, um den Schalungsträger 1 standsicher stapeln zu können. Dabei werden die Gurte des Hohlprofils 4 durch die erste Seitenwand 5 und eine dritte Seitenwand 14 ausgebildet. Die erste und dritte Seitenwand 5, 14 werden durch die an die erste anschließende Seitenwand 11, 16 verbunden, welche spiegelsymmetrisch zueinander ausgeführt ist und damit parallel verlaufende Stege am Hohlprofil 4 ausbilden.The hollow profile 4 also has a rectangular cross section in order to stack the formwork support 1 stable. In this case, the straps of the hollow profile 4 are formed by the first side wall 5 and a third side wall 14. The first and third side wall 5, 14 are connected by the adjoining the first side wall 11, 16, which is mirror-symmetrical to each other and thus forming parallel webs on the hollow section 4.

Unterhalb der Zugangsöffnungen 12 sind in dem Hohlprofil 4 zusätzlich Längssicken 17 vorgesehen, die die Formstabilität des Hohlprofils 4 erhöhen und zugleich eine Grifffläche zur besseren Handhabung ausbilden. Die Längssicken 17 sind hierbei halbrund ausgestaltet.Below the access openings 12 additional longitudinal beads 17 are provided in the hollow section 4, which increase the dimensional stability of the hollow section 4 and at the same time form a gripping surface for better handling. The longitudinal corrugations 17 are in this case designed semicircular.

Zusätzlich zu den Längssicken 17 weist das Hohlprofil an seinen beiden vertikalen Seitenwänden 11, 16 mittig eine Lochreihe 18 mit kreisrunden Löcher 19 auf, die in einem nach innen gebogenen Öffnungsrand 20 auslaufen, um trotz Gewichtsreduktion hohe Verwindungssteifigkeit am Schalungsträger 1 zu gewährleisten.In addition to the longitudinal corrugations 17, the hollow profile at its two vertical side walls 11, 16 centered on a row of holes 18 with circular holes 19 which terminate in an inwardly curved opening edge 20 to ensure high torsional stiffness on the formwork support 1 despite weight reduction.

Die von den Profilschenkeln 7 der ersten Seitenwand 5 ausgebildete Längsnut 6 weist insbesondere, wie in Fig. 2 dargestellt, keine Hinterschneidungen auf und ist demnach als hinterschneidungsfreie Längsnut ausgeführt 6. Dadurch kann ein einfaches Austauschen der nagelbaren Leiste 2 in der Längsnut 6 erfolgen. Zusätzlich verläuft die nagelbare Leiste 2 plan mit der ersten Seitenwand 5, wodurch sich eine stabile, vergleichsweise großflächige Auflage für ein zu montierendes Schalungselement 21 ergibt.The trained by the profile legs 7 of the first side wall 5 longitudinal groove 6 has in particular, as in Fig. 2 represented, no undercuts and is therefore designed as a non-undercut longitudinal groove 6. This allows a simple replacement of the nailable bar 2 in the longitudinal groove 6 done. In addition, the nailable strip 2 is flush with the first side wall 5, resulting in a stable, comparatively large-area support for a shuttering element 21 to be mounted.

Wie in Fig. 2 dargestellt, bildet das Hohlprofil 4 mit seiner dritten Seitenwand 14 eine T-förmige Nut 22 aus. Eine solche T-förmige Nut 22 kann sich insbesondere für Aufnahme von, nicht näher dargestellten, Verbindungsmitteln eignen. Solche Verbindungsmittel können etwa zur Befestigung des Schalungsträgers 1 an einem Gestell dienen.As in Fig. 2 illustrated, the hollow section 4 forms with its third side wall 14 a T-shaped groove 22. Such a T-shaped groove 22 may be particularly suitable for receiving, not shown, connecting means. Such connection means can serve for example for fastening the formwork support 1 to a frame.

Gemäß Fig. 1 ist schematische eine Betonschalung 100 dargestellt, welche ein Schalungselement 21 und einen erfindungsgemäßen Schalungsträger 1 aufweist. Das Schalungselement 21 kann insbesondere eine Schaltafel aus einem holzartigen Material sein. Zur Befestigung des Schalungselements 21 auf dem Schalungsträger 1, ist das Schalungselement 21 mit der im Schalungsträger 1 befestigten nagelbaren Leiste 2 vorzugsweise vernagelt. Es ist jedoch auch vorstellbar, dass das Schalungselement 21 mit der nagelbaren Leiste 2 verschraubt ist.According to Fig. 1 schematically a concrete formwork 100 is shown, which has a formwork element 21 and a formwork support 1 according to the invention. The formwork element 21 may in particular be a formwork panel made of a wood-like material. For fixing the formwork element 21 on the formwork support 1, the formwork element 21 is preferably nailed to the nailable bar 2 fastened in the formwork support 1. However, it is also conceivable that the formwork element 21 is bolted to the nailable bar 2.
