Description

Die Erfindung betrifft eine Tragvorrichtung für eine Betonschalung, insbesondere eine Deckenschalung, mit zumindest einem zwei Längsträger aufweisenden Mehrfachträger, wobei die Längsträger über zumindest ein Verbindungselement miteinander verbunden sind.The invention relates to a supporting device for a concrete formwork, in particular a slab formwork, with at least one two longitudinal carrier having multiple carriers, wherein the longitudinal members are connected to each other via at least one connecting element.

Aus der FR 2 955 877 A1 ist eine gattungsgemäße Tragvorrichtung für eine Schalungsstruktur aus Betonplatten bekannt. Die Tragvorrichtung weist eine aus zwei Längsträgern zusammengesetzte Einheit auf, welche über verstellbare Verbindungsstreben miteinander verbunden sind. In einer ersten Ausführung bestehen die Verbindungsstreben aus zwei gelenkig miteinander verbundenen Teilen, welche jeweils über ein Gelenk schwenkbar an dem zugehörigen Längsträger gelagert sind. Durch Verschwenken der Teile zueinander kann der Abstand zwischen den Längsträgern verändert werden. Darüber hinaus wird eine zweite Ausführung beschrieben, bei welcher die Verbindungsstrebe gelenkig an dem einen Längsträger und in einer Längsführung verschieblich an dem anderen Längsträger gelagert ist.From the FR 2 955 877 A1 is a generic support device for a formwork structure made of concrete slabs known. The support device has a unit composed of two longitudinal members, which are connected to each other via adjustable connecting struts. In a first embodiment, the connecting struts of two articulated interconnected parts, which are each mounted via a hinge pivotally mounted on the associated side member. By pivoting the parts to each other, the distance between the longitudinal members can be changed. In addition, a second embodiment is described, in which the connecting strut is articulated on the one longitudinal carrier and in a longitudinal guide slidably mounted on the other side member.

Bei diesem Stand der Technik kann daher bereits der Abstand zwischen den Längsträgern durch verstellbare Verbindungselemente eingestellt werden. Nachteiligerweise sind jedoch an die Längsträger fix angebrachte Achsen und Gelenke erforderlich, um die Verstellung der Längsträger zu ermöglichen. Eine solche Ausführung ist konstruktiv aufwendig und bringt hohe Fertigungskosten mit sich. Darüber hinaus ist es nachteilig, dass durch Schmutzablagerungen an den Gelenken bzw. in der Längsführung Funktionseinbußen auftreten können.In this prior art, therefore, the distance between the longitudinal beams can already be adjusted by adjustable connecting elements. Disadvantageously, however, the longitudinal support fixedly mounted axes and joints are required to allow the adjustment of the side members. Such a design is structurally complex and brings high production costs. In addition, it is disadvantageous that functional deposits can occur due to dirt deposits on the joints or in the longitudinal guide.

Die Holzbalken sind abwechselnd mit der breiteren und mit der schmäleren Basisfläche nach unten gekehrt. Je zwei benachbarte Balken sind an ihren Enden mittels Seil- bzw. Kabelzügen miteinander verbunden. In den Endabschnitten der Balken sind je zwei Zugfedern untergebracht. An den einander zugekehrten Federenden ist je eine Rolle angebracht. Zum Gebrauch der Vorrichtung lassen sich die Balken federnd auseinanderziehen, wodurch ein Tragrost gebildet wird, auf dem die beim Betonieren z.B. einer Decke verwendeten Schalbretter aufgelegt werden.document CH 364 891 A refers to a supporting device for formwork boards, which has a plurality of parallel juxtaposed beams. The wooden beams are turned alternately with the wider and with the narrower base surface down. Each two adjacent beams are connected at their ends by means of cable or cable trains. Two tension springs are accommodated in the end sections of the beams. At the facing spring ends a roller is ever attached. To use the device, the beams can be resiliently apart, creating a support grid is formed on which the formwork used when concreting eg a ceiling boards are placed.

Aus der FR 2 842 848 A1 und FR 2 900 176 A1 sind weitere Tragvorrichtungen für Deckenschalungen bekannt, welche jedoch hinsichtlich der Nachteile des oben diskutierten Standes der Technik keine darüber hinausgehenden Lösungsansätze bieten.From the FR 2 842 848 A1 and FR 2 900 176 A1 Further support devices for slab formworks are known which, however, offer no further solutions with regard to the disadvantages of the prior art discussed above.

Die DE 102 34 445 A1 beschreibt ein Deckenschalungssystem aus Trägerpaketen, die über Holme miteinander verbunden sind.The DE 102 34 445 A1 describes a slab formwork system consisting of carrier packages which are connected to one another via bars.

Die US 3,841,597 offenbart eine Trageinrichtung für eine andersartige Bodenkonstruktion.The US 3,841,597 discloses a support device for a different floor construction.

Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, eine dauerhafte, zuverlässig funktionierende Tragvorrichtung der eingangs angeführten Art zu schaffen, welche eine Verstellung der Längsträger des Mehrfachträgers zueinander mit konstruktiv einfachen Mitteln ermöglicht.In contrast, the object of the present invention is to provide a durable, reliable functioning support device of the type mentioned, which allows an adjustment of the side members of the multi-carrier to each other with structurally simple means.

Diese Aufgabe wird durch eine Tragvorrichtung mit den Merkmalen von Anspruch 1 gelöst.This object is achieved by a support device with the features of claim 1.

Erfindungsgemäß ist eine den Längsträger durchsetzende Durchtrittsöffnung vorgesehen, wobei das Verbindungselement verschieblich in der Durchtrittsöffnung des Längsträgers angeordnet ist. Die Durchtrittsöffnung erstreckt sich hierbei von der dem jeweils anderen Längsträger zugewandten Seitenfläche bis zu der vom anderen Längsträger abgewandten Seitenwand des Längsträgers, so dass das Verbindungselement den jeweiligen Längsträger vollständig durchsetzt. Je nach eingestelltem Abstand zwischen den Längsträgern ragt das Verbindungselement entsprechend weit aus dem Längsträger nach außen, weg von dem jeweils anderen Längsträger, vor. Demnach kann der Längsträger zur Verringerung des Abstands zwischen den Längsträgern entlang des Verbindungselements nach innen, in Richtung des anderen Längsträgers, geschoben werden. Um den Abstand zwischen den Längsträgern zu vergrößern, wird der Längsträger entlang des Verbindungselements nach außen verschoben. Dabei wird das Verbindungselement zumindest in eine Richtung im Wesentlichen senkrecht zur Längsrichtung des Längsträgers bzw. in Längsrichtung des Verbindungselements verschoben. Erfindungsgemäß kann das Verbindungselement hierbei jedoch zugleich in Längsrichtung eines der beiden Längsträger in der entsprechenden Durchtrittsöffnung verschoben werden. Mittels der Durchtrittsöffnung zur verschieblichen Anordnung des Verbindungselements kann der Abstand zwischen den Längsträgern des Mehrfachträgers auf besonders einfache Weise verändert werden. Vorteilhafterweise kann bei der erfindungsgemäßen Ausführung auf fix angebrachte Schwenkachsen zur Lagerung des Verbindungselements verzichtet werden, welche beim Stand der Technik einerseits konstruktiv aufwendig und zudem anfällig für Funktionseinbußen waren. Demgegenüber ist das erfindungsgemäße Verbindungselement achsfrei, d.h. ohne fix am Längsträger angebrachte Achsen, in der Durchtrittsöffnung des Längsträgers gehalten. Damit kann konstruktiv einfache Tragvorrichtung erzielt werden, welche sich insbesondere auch durch geringe Fertigungskosten auszeichnet. Der Mehrfachträger ist bevorzugt als Doppelträger mit genau zwei Längsträgern ausgeführt, wobei bei einer alternativen Ausführung mehr als zwei Längsträger vorgesehen sind.
Die Längsträger weisen jeweils eine Durchtrittsöffnung zum Durchtritt des Verbindungselements auf. Dabei sind an beiden Längsträgern Durchtrittsöffnungen ausgebildet, wobei das Verbindungselement quer zur Längsrichtung des Längsträgers bzw. in Längsrichtung des Verbindungselements verschieblich in den Durchtrittsöffnungen gehalten ist. Demnach sind beide Längsträger verschieblich auf dem Verbindungselement angeordnet. Zur Einstellung des gewünschten Abstands zwischen den Längsträgern wird zumindest einer der Längsträger entlang des Verbindungselements verschoben, wobei das Verbindungselement um eine entsprechende Strecke von der Halteöffnung des Längsträgers nach außen vorgeschoben wird. Je nach Abstand zwischen den Längsträgern steht das Verbindungselement entsprechend weit von der äußeren Seitenwand des Längsträgers nach außen vor.
Das Verbindungselement ist in zumindest einer der Durchtrittsöffnungen der Längsträger im Wesentlichen passgenau angeordnet, so dass das Verbindungselement bei der Verschiebung durch die Durchtrittsöffnung auf eine vorgegebene Richtung gezwungen werden kann. Daher weisen die Durchtrittsöffnung und das Verbindungselement erfindungsgemäß entsprechende Querschnittsflächen auf. Durch Verschieben des Längsträgers entlang des Verbindungselements kann der Abstand zwischen den Längsträgern verändert werden.
Für diese Zwecke ist es günstig, wenn das Verbindungselement im Querschnitt im Wesentlichen kreisförmig ist, wobei die Durchtrittsöffnung zur passgenauen Anordnung des Längsträgers als Rundloch ausgebildet ist. Das Verbindungselement ist bevorzugt rohrförmig ausgebildet.According to the invention, a passage opening passing through the longitudinal member is provided, wherein the connecting element is arranged displaceably in the passage opening of the longitudinal member. In this case, the through opening extends from the side surface facing the respective other side member to the side wall of the side member facing away from the other side member, so that the connecting element completely penetrates the respective side member. Depending on the set distance between the longitudinal members, the connecting element protrudes correspondingly far out of the longitudinal member to the outside, away from the respective other longitudinal member. Accordingly, the longitudinal member to reduce the distance between the longitudinal members along the connecting element inwardly, in the direction of the other longitudinal member, are pushed. In order to increase the distance between the longitudinal members, the longitudinal member along the connecting element is displaced outwards. In this case, the connecting element is displaced at least in one direction substantially perpendicular to the longitudinal direction of the longitudinal member or in the longitudinal direction of the connecting element. According to the invention, however, the connecting element can in this case at the same time be displaced in the longitudinal direction of one of the two longitudinal members in the corresponding passage opening. By means of the passage opening for displaceable arrangement of the connecting element, the distance between the longitudinal members of the multi-carrier can be changed in a particularly simple manner. Advantageously, in the embodiment according to the invention can be dispensed with fixedly mounted pivot axes for mounting the connecting element, which in the prior art on the one hand structurally complex and also prone to loss of function. In contrast, the connecting element according to the invention is free of axle, ie without fixedly attached to the longitudinal member axles, in the passage opening held the longitudinal beam. This can be achieved structurally simple support device, which is characterized in particular by low production costs. The multiple carrier is preferably designed as a double carrier with exactly two longitudinal members, wherein in an alternative embodiment more than two longitudinal members are provided.
The longitudinal members each have a passage opening for the passage of the connecting element. In this case, passage openings are formed on both longitudinal members, wherein the connecting element is held transversely to the longitudinal direction of the longitudinal member or in the longitudinal direction of the connecting element displaceable in the passage openings. Accordingly, both longitudinal members are arranged displaceably on the connecting element. To set the desired distance between the longitudinal members at least one of the longitudinal members is displaced along the connecting element, wherein the connecting element is advanced by a corresponding distance from the holding opening of the longitudinal member to the outside. Depending on the distance between the longitudinal members, the connecting element projects correspondingly far outward from the outer side wall of the longitudinal member.
The connecting element is arranged substantially accurately in at least one of the passage openings of the longitudinal members, so that the connecting element can be forced to a predetermined direction during the displacement through the passage opening. Therefore, the passage opening and the connecting element according to the invention have corresponding cross-sectional areas. By moving the longitudinal member along the connecting element, the distance between the longitudinal members can be changed.
For this purpose, it is expedient for the connecting element to be substantially circular in cross-section, with the passage opening being designed as a round hole for accurately fitting the longitudinal carrier. The connecting element is preferably tubular.

Andererseits ist das Verbindungselement in zumindest einer der Durchtrittsöffnungen in Längsrichtung des Längsträgers verschieblich angeordnet. Dadurch kann nicht nur der Abstand zwischen den Längsträgern, sondern zudem auch der Winkel zwischen den Längsachsen der Längsträger eingestellt werden. Vorteilhafterweise kann damit die Stellung des Winkelträgers auf besonders einfache Weise an die jeweiligen Bedingungen auf der Baustelle angepasst werden.
Hierbei ist es günstig, wenn die Durchtrittsöffnung zur in Längsrichtung verschieblichen Anordnung des Längsträgers als Langloch ausgebildet ist. Das Langloch weist in Längsrichtung eine größere Erstreckung als das Verbindungselement auf, so dass das Verbindungselement entlang des Langlochs verschieblich ist. Andererseits ist es günstig, wenn das Verbindungselement in Querrichtung des Langlochs passgenau, d.h. ohne Spiel, in dem Langloch angeordnet ist, so dass das Verbindungselement bei der Verschiebung entlang des Langlochs geführt wird.
Um einerseits den Abstand zwischen den Längsträgern und andererseits die Winkelstellung der Längsträger auf einfache Weise anpassen zu können, ist erfindungsgemäß das Verbindungselement im Wesentlichen passgenau in der Durchtrittsöffnung des einen Längsträgers und in Längsrichtung des Längsträgers verschieblich in der Durchtrittsöffnung des anderen Längsträgers angeordnet.
Um die Längsträger in einer vorgegebenen Ebene zu fixieren, ist es günstig, wenn die Längsträger jeweils zumindest zwei in Längsrichtung beabstandete Durchtrittsöffnungen zum Durchtritt von zwei Verbindungselementen aufweisen. Gemäß dieser Ausführung sind zwischen den Längsträgern zumindest zwei Verbindungselemente vorgesehen, welche die gegenüberliegenden Durchtrittsöffnun gen der Längsträger durchsetzen.On the other hand, the connecting element is arranged displaceably in at least one of the passage openings in the longitudinal direction of the longitudinal member. As a result, not only the distance between the longitudinal members, but also the angle between the longitudinal axes of the side members can be adjusted. Advantageously, so that the position of the angle bracket can be adapted in a particularly simple manner to the particular conditions on the site.
It is advantageous if the passage opening is designed to be displaceable in the longitudinal direction of the longitudinal member arrangement as a slot. The slot has a greater extent in the longitudinal direction than the connecting element, so that the connecting element is displaceable along the slot. On the other hand, it is advantageous if the connecting element in the transverse direction of the slot accurately, ie without clearance, is arranged in the slot, so that the connecting element is guided during the displacement along the slot.
On the one hand to be able to easily adjust the distance between the longitudinal members and on the other hand, the angular position of the longitudinal beams, the connecting element according to the invention is arranged substantially accurately in the passage opening of a longitudinal member and in the longitudinal direction of the longitudinal member displaceable in the passage opening of the other longitudinal member.
In order to fix the longitudinal members in a predetermined plane, it is favorable if the longitudinal members each have at least two longitudinally spaced passage openings for the passage of two connecting elements. According to this embodiment, at least two connecting elements are provided between the longitudinal members, which the opposite Durchtrittsöffnun enforce the longitudinal beams.

Besonders vorteilhaft ist es, wenn die Verbindungselemente jeweils im Wesentlichen passgenau in der einen Durchtrittsöffnung und in Längsrichtung des Längsträgers verschieblich in der anderen Durchtrittsöffnung der in Längsrichtung beabstandeten Durchtrittsöffnungen der Längsträger angeordnet sind. Hiermit kann vorteilhafterweise der Abstand und die Winkelstellung der Längsträger zueinander eingestellt werden. Zur winkeligen Anordnung der Längsträger können die Längsträger unterschiedlich weit auf die Verbindungselemente aufgeschoben werden. Bei dieser Ausführung sind zudem die Längsträger in Längsrichtung zueinander fixiert. Vorteilhafterweise können daher der Querabstand und der Winkel zwischen den Längsträgern angepasst werden, ohne hierbei die Längsträger in Längsrichtung zueinander zu verschieben.It is particularly advantageous when the connecting elements are arranged in each case substantially accurately in one passage opening and in the longitudinal direction of the longitudinal carrier displaceable in the other passage opening of the longitudinally spaced passage openings of the longitudinal members. Hereby advantageously the distance and the angular position of the longitudinal members can be adjusted to each other. For angular arrangement of the longitudinal members, the longitudinal members can be pushed to different lengths on the connecting elements. In this embodiment, the longitudinal members are also fixed to each other in the longitudinal direction. Advantageously, therefore, the transverse spacing and the angle between the longitudinal members can be adjusted without moving the longitudinal members in the longitudinal direction to each other.

Zur Einstellung eines maximalen Abstands bzw. eines maximalen Winkels zwischen den Längsträgern ist es von Vorteil, wenn das Verbindungselement an einem durch die Durchtrittsöffnung durchtretenden Ende mit einem äußeren Anschlagelement verbunden ist, mit welchem die Verschiebung des Längsträgers nach außen begrenzbar ist. Das äußere Anschlagelement ist hierbei auf der vom jeweils gegenüberliegenden Längsträger abgewandten Seite des Längsträgers angeordnet. Um die Anschlagfunktion zu erfüllen, weist das Anschlagelement eine größere Erstreckung als die zugehörige Durchtrittsöffnung des Längsträgers auf. Bei Erreichen einer äußeren Anschlagstellung wird die Verschiebung des Längsträgers entlang des Verbindungselements nach außen, d.h. weg von dem jeweils anderen Längsträger, durch das äußere Anschlagelement blockiert. Somit wird durch das äußere Anschlagelement der maximale Abstand zwischen den Längsträgern bzw. der maximale Winkel zwischen den Längsträgern festgelegt.To set a maximum distance or a maximum angle between the longitudinal members, it is advantageous if the connecting element is connected at an end passing through the passage opening with an outer stop element, with which the displacement of the longitudinal member is limited to the outside. The outer stop element is in this case arranged on the side facing away from the respective longitudinal side member of the longitudinal member. In order to fulfill the stop function, the stop element has a greater extent than the associated passage opening of the longitudinal member. Upon reaching an outer stop position, the displacement of the side member along the connecting element to the outside, i. away from the other side member, blocked by the outer stop member. Thus, the maximum distance between the longitudinal members or the maximum angle between the longitudinal members is determined by the outer stop element.

Zur Begrenzung der Verschiebung des Längsträgers ist es günstig, wenn als äußeres Anschlagelement ein aufgeweiteter Endbereich des Verbindungselements oder ein auf dem Verbindungselement angeordnetes Scheibenelement oder ein durch eine Querbohrung des Verbindungselements gestecktes Bolzenelement vorgesehen ist. Hierbei können verschiedenste Ausführungen des äußeren Anschlagelements vorgesehen sein. Die Verwendung eines aufgeweiteten Endbereichs als Anschlagelement ist hinsichtlich des Fertigungs- und Montageaufwands besonders günstig. Wenn als Anschlagelement ein Scheibenelement oder ein Bolzenelement vorgesehen ist, kann ein besonders einfaches, beispielsweise rohrförmiges, Verbindungselement verwendet werden, auf welchem das scheiben- oder bolzenförmige Anschlagelement montiert ist.To limit the displacement of the longitudinal member, it is advantageous if a widened end region of the connecting element or a disk element arranged on the connecting element or a bolt element inserted through a transverse bore of the connecting element is provided as the outer stop element. In this case, various embodiments of the outer stop element can be provided. The use of a widened End region as a stop element is particularly favorable in terms of manufacturing and assembly costs. If a disc element or a bolt element is provided as a stop element, a particularly simple, for example, tubular, connecting element can be used, on which the disk-shaped or bolt-shaped stop element is mounted.

Zur Einstellung eines minimalen Abstands zwischen den Längsträgern ist es vorteilhaft, wenn das Verbindungselement zwischen den Längsträgern mit einem inneren Anschlagelement verbunden ist, mit welchem die Verschiebung des Längsträgers nach innen begrenzbar ist. Bei Erreichen der inneren Anschlagstellung ist der Längsträger gegen eine weitere Verschiebung nach innen, d.h. in Richtung des jeweils anderen Längsträgers, blockiert. Wenn das Verbindungselement in beiden gegenüberliegenden Durchtrittsöffnungen verschieblich ist, weist das innere Anschlagelement bevorzugt je eine Anschlagfläche zur Begrenzung der Verschiebung des einen Längsträgers und eine weitere Anschlagfläche zur Begrenzung der Verschiebung des anderen Längsträgers auf. Der minimale Abstand ist bevorzugt so bemessen, dass in der inneren Anschlagstellung zwischen den Längsträgern des Mehrfachträgers ein weiterer Längsträger eines anderen, in Längsrichtung folgenden Mehrfachträgers anordenbar ist.To set a minimum distance between the longitudinal members, it is advantageous if the connecting element between the longitudinal members is connected to an inner stop element, with which the displacement of the longitudinal member can be limited inwardly. Upon reaching the inner stop position, the side member is against further inward displacement, i. in the direction of the other longitudinal member, blocked. If the connecting element is displaceable in both opposite passage openings, the inner stop element preferably each has a stop surface for limiting the displacement of one longitudinal carrier and a further stop surface for limiting the displacement of the other longitudinal carrier. The minimum distance is preferably dimensioned such that in the inner stop position between the longitudinal members of the multi-carrier another longitudinal member of another, in the longitudinal direction following multiple carrier can be arranged.

Zur Erzielung der inneren Anschlagstellung ist es günstig, wenn als inneres Anschlagelement ein um das Verbindungselement angeordnetes Hülsenelement bzw. auch ein Scheiben- oder Bolzenelement vorgesehen ist. Das Hülsenelement kann über eine Schweißverbindung mit dem Verbindungselement verbunden sein. Gemäß einer alternativen Ausführung weist das Verbindungselement zwischen den Längsträgern eine Querschnittsveränderung, beispielsweise eine Stauchung, auf, mit welcher die Verschiebung des Längsträgers nach innen, über die Querschnittsveränderung hinaus, blockierbar ist.To achieve the inner stop position, it is advantageous if a sleeve element or a disk or bolt element arranged around the connecting element is provided as the inner stop element. The sleeve element can be connected to the connecting element via a welded connection. According to an alternative embodiment, the connecting element between the longitudinal members on a cross-sectional change, for example, a compression, with which the displacement of the longitudinal member inwardly beyond the cross-sectional change addition, can be blocked.

Um den Mehrfachträger gegen ein Verrutschen auf einem Primärträger zu sichern, ist es günstig, wenn zumindest ein Längsträger an zumindest einer Stirnseite einen Anschlag aufweist, welcher, bezogen auf die Betriebsstellung, von der Unterseite des Längsträgers nach unten vorsteht. Hiermit kann die Sicherheit beim Aufbau der Tragvorrichtung erhöht werden. Dies ist insbesondere dann vorteilhaft, wenn auf der Tragvorrichtung eine Schalungsplatte montiert wird. Darüber hinaus kann hiermit die Stirnseite des Längsträgers geschützt werden. Der Anschlag kann leistenförmig an der stirnseitigen Unterkante des Längsträgers ausgebildet sein. Alternativ kann der Anschlag am unteren Ende einer Abdeckplatte ausgebildet sein, welche bevorzugt die Stirnseite des Längsträgers abdeckt. Hiermit kann die Montage des Mehrfachträgers vereinfacht werden.In order to secure the multiple carrier against slipping on a primary carrier, it is advantageous if at least one longitudinal carrier has at least one end face a stop which, based on the operating position, protrudes from the underside of the longitudinal carrier downwards. This can help with security Structure of the support device can be increased. This is particularly advantageous when a formwork panel is mounted on the support device. In addition, hereby the front side of the longitudinal member can be protected. The stop may be strip-shaped formed on the front-side lower edge of the longitudinal member. Alternatively, the stop may be formed at the lower end of a cover plate, which preferably covers the end face of the longitudinal member. Hereby, the assembly of the multi-carrier can be simplified.

Darüber hinaus ist es günstig, wenn zumindest einer der Längsträger eine oberseitige Ausnehmung zur insbesondere lösbaren Aufnahme einer Befestigungsleiste für eine Schalungsplatte aufweist. Zur Befestigung der Schalungsplatte ist die Befestigungsleiste nagelbar, d.h. mit Nägeln versehbar. Zur Ausbildung der Ausnehmung ist es insbesondere günstig, wenn der Längsträger als Profilelement, insbesondere als Strangpressprofil, ausgebildet ist. Das Profilelement weist Seitenwände auf, in welchen die Durchtrittsöffnung ausgebildet ist. Bevorzugt weist das Profilelement zudem eine nach oben, d.h. in Richtung der Auflagefläche für die Schalungsplatte, aufgeweitete Querschnittsform auf. Bevorzugt ist das Profilelement aus Aluminium gefertigt. Das Verbindungselement kann ebenfalls aus Aluminium hergestellt sein. Aus Festigkeitsgründen kann das Verbindungselement aber auch aus Stahl gefertigt sein. Diese Ausführung ist aus Stabilitätsgründen vorteilhaft. Zudem kann bei dieser Ausführung das Verbindungselement zur Ausbildung des inneren Anschlagelements auf besonders einfache Weise eine Stauchung aufweisen. Nachteilig an der Ausführung des Verbindungselements aus Stahl ist die Gewichtszunahme gegenüber einer Ausführung aus Aluminium.Moreover, it is favorable if at least one of the longitudinal members has an upper-side recess for the particular detachable reception of a fastening strip for a shuttering panel. To fix the formwork panel, the fixation bar is nailable, i. with nails. To form the recess, it is particularly advantageous if the longitudinal member is designed as a profile element, in particular as an extruded profile. The profile element has side walls, in which the passage opening is formed. In addition, the profile element preferably has an upward, i. in the direction of the support surface for the formwork panel, expanded cross-sectional shape. Preferably, the profile element is made of aluminum. The connecting element may also be made of aluminum. For reasons of strength, the connecting element can also be made of steel. This design is advantageous for reasons of stability. In addition, in this embodiment, the connecting element for forming the inner stop element in a particularly simple manner have a compression.
