Description

Die Erfindung betrifft eine Kombination eines Querträgers und eines Längsträgers wobei der Längsträger an beiden Seiten versehen ist mit einem einen aufstehenden Rand aufweisenden Tragflansch und einen oberen Flansch welcher seitlich in bezug auf den vertikalen Steg eines Längsträgers ausragt, wobei der Querträger an mindestens einem Längsende mit einem hakenförmigen Ende zum über den aufstehenden Rand des Längsträgers hin Haken versehen ist.The invention relates to a combination of a cross member and a side member, the side member being provided on both sides with a supporting flange having an upstanding edge and an upper flange which projects laterally with respect to the vertical web of a side member, the cross member having at least one longitudinal end hook-shaped end to the hook is provided over the upstanding edge of the side member.

Eine derartige Konstruktion ist bekannt aus der EU-Patentanmeldung Nr. 86.202.129.2 von Anmelderin. Diese Kombination aus Querträgern und Längsträgern wird als eine Trägerkonstruktion für Schalungsplatten für das Schalen von Betondecken bei der Utilitätsbau verwendet.Such a construction is known from the applicant's EU patent application No. 86.202.129.2. This combination of crossbeams and side members is used as a support structure for formwork panels for the formwork of concrete slabs in utility construction.

Bei der bekannten Konstruktion mit allen diesbezüglichen Vorteilen kann nach dem über den Rand des Längsträgers Einhaken eines Querträgers dieser Querträger eine derartige Bewegungsfreiheit nach oben aufweisen daß dieser ausser Position geraten kann. Dieses kann insbesondere auftreten wenn ein Querträger nur an einem Ende in einem Längsträger montiert worden ist und das andere Ende frei auf einer Stahlrohrstütze auskragt. Für die sich auf die Bodenschalungsplatten befindenden Personen kann dieses zu unerwünschten Situationen führen.In the known construction with all the advantages in this regard, after hooking a cross member over the edge of the longitudinal member, this cross member can have such freedom of movement upwards that it can get out of position. This can occur in particular if a cross member has only been mounted on one end in a side member and the other end is freely cantilevered on a tubular steel support. This can lead to undesirable situations for the people on the floor formwork panels.

Bei der bekannten Konstruktion liegt die obere Seite des Querträgers in bezug auf die obere Seite des Längsträgers auf einer festen Ebene. Wenn die obere Seite des Querträgers in der selben Ebene als die obere Seite des Längsträgers liegt, werden die Schalungsplatten auf den Längsträger gelegt. Wenn die obere Seite des Querträgers niedriger liegt als die obere Seite des Längsträgers, werden Schalungsplatten einer bestimmten Dicke zwischen den Längsträgern gelegt, derart daß die obere Seite der Schalungsplatten in derselben Ebene mit der oberen Seite des Längsträgers liegt. Eine Kombination der beiden Lösungen ist in der genannten Patentanmeldung nicht möglich.In the known construction, the upper side of the cross member is on a fixed plane with respect to the upper side of the side member. If the upper side of the cross member lies in the same plane as the upper side of the side member, the formwork panels are placed on the side member. If the upper side of the cross member is lower than the upper side of the side member, formwork panels of a certain thickness are placed between the side members so that the top side of the formwork panels is in the same plane with the top side of the Longitudinal beam. A combination of the two solutions is not possible in the patent application mentioned.

Die Erfindung bezweckt nun eine Konstruktion zu schaffen wobei der Querträger nicht mehr in bezug auf den Längsträger ausser Position geraten kann, wodurch eine für die sich auf dieser Trägerkonstruktion befindenden Personen im allgemeinen eine noch größere Sicherheit erhalten wird, und ausserdem diese Konstruktion sich insbesondere eignet um einen Querträger in eindeutig gesicherter Weise zwischen zwei angebrachten, parallelen Längsträgern anzuordnen.The invention now aims to provide a construction in which the cross member can no longer get out of position with respect to the side member, which generally provides an even greater level of safety for the persons on this support construction, and this construction is also particularly suitable for to arrange a cross member in a clearly secured manner between two attached, parallel side members.

Gemäß der Erfindung wird dieses nun erreicht mit einer Konstruktion die dadurch gekennzeichnet ist, daß das Ende des Querträgers so ausgeführt ist daß dieser Träger in einem um seine Längsachse verdrehten ersten Kipposition über den Rand des Tragflansches des Längsträgers hin gehakt werden kann und durch Verdrehung um seine Längsachse in eine zweite Kipposition bringbar ist in welcher der Querträger zwischen dem aufstehenden Rand des Tragflansches und dem oberen Flansch des Längsträgers gesichert ist.According to the invention, this is now achieved with a construction which is characterized in that the end of the cross member is designed such that this carrier can be hooked over the edge of the supporting flange of the side member in a first tilt position rotated about its longitudinal axis and by twisting around it Longitudinal axis can be brought into a second tilting position in which the cross member is secured between the upstanding edge of the supporting flange and the upper flange of the longitudinal member.

Figur 4 eine Auflegung eines Querträgers in einem Längsträger zeigt, nachdem der Querträger um 90° um seine Längsachse verdreht ist, wodurch die Sicherung unterhalb des oberen Flansches des Längsträgers zum Stande gekommen ist,FIG. 4 shows the placement of a cross member in a side member after the cross member has been rotated by 90 ° about its longitudinal axis, as a result of which the securing has been achieved below the upper flange of the side member.

Figur 4a einen Querschnitt entlang B-B aus der Figur 4 ist,Figure 4a shows a cross section along BB from the Figure 4 is

Figur 5 einen Längsträger zeigt welcher an einem Ende in den Längsträger gehakt werden kann und dieser danach an seinem anderen Ende in die senkrechte Ebene hochbewegt werden kann, wodurch das Ende des Querträgers unterhalb des oberen Flansches des Längsträgers gerät,FIG. 5 shows a side member which can be hooked into the side member at one end and which can then be moved upwards into the vertical plane at its other end, as a result of which the end of the cross member comes below the upper flange of the side member,

Figur 6 in perspektivischer Weise eine Ausführungsform des in den Längsträger zu befestigen einen Endes des Querträgers darstellt undFIG. 6 shows in perspective an embodiment of one end of the cross member to be fastened in the longitudinal member and

Figur 7 die Auflegung eines Querträgers in einem Längsträger darstellt, wobei der Querträgerbalken in bezug auf das Trägerende um 180° verdreht werden kann, wodurch die obere Seite des Querträgers in bezug auf die obere Seite des Längsträgers in eine andere Ebene kommt.Figure 7 illustrates the placement of a cross member in a side member, wherein the cross member beam can be rotated by 180 ° with respect to the end of the member, whereby the upper side of the cross member comes into a different plane with respect to the upper side of the side member.

Wie aus der Figur 1 ersichtlich ist, wird eine Unterstützung für eine Bodenschalung aus einem Gitter von Längsträgern 1 und Querträgern 2 gebildet. Das Ganze wird von zum Beispiel nicht näher dargestellten Stahlrohrstützen in einer bestimmten Höhe gehalten und wird durch Plattenmaterial abgedeckt. Der Längsträger weist einen Steg mit an beiden Seiten einen durchgehenden Tragflansch 5 mit aufstehendem Rand 6 auf. Der Querträger 2 hat ein Ende welches mit einem hakenförmigen Kopf 15 versehen ist welcher um den aufstehenden Rand 6 des Längsträgers herum haken kann (Figur 5). Der Querträger verbleibt dadurch in Position daß das Ende 7 sich unterhalb des ausragenden Flansches 9 des Längsträgers befindet.As can be seen from FIG. 1, support for a floor formwork is formed from a grid of longitudinal beams 1 and cross beams 2. The whole is held at a certain height by, for example, steel pipe supports, not shown, and is covered by plate material. The longitudinal member has a web with a continuous support flange 5 on both sides with a raised edge 6. The cross member 2 has an end which is provided with a hook-shaped head 15 which can hook around the upstanding edge 6 of the side member (FIG. 5). The cross member remains in position in that the end 7 is located below the projecting flange 9 of the side member.

Am Rande einer anzuordnenden Betondecke wird die Verschalung auskragen müssen damit eine Stirnschalung und Geländerpfosten angeordnet werden können. Dazu ist es zweckvoll daß die Längsträger über einer Stütze in Form eines Balkens mit z.B. Stahlrohrstützen auskragen. Wäre nun der Querträger im Bereich des Längsträgers nicht nach oben hin gesichert, so könnte die Gefahr entstehen daß der Querträger aus dem Längsträger kippt mit allen Folgen davon für die sich unterhalb der Decke befindenden Personen.At the edge of a concrete slab to be arranged, the formwork will protrude so that face formwork and railing posts can be arranged. For this purpose, it is useful that the side members over a support in the form of a beam with e.g. Cantilever steel tube supports. If the cross member were not secured upwards in the area of the side member, there could be a risk that the cross member tilts out of the side member with all its consequences for the people below the ceiling.

Die Querträger müssen an jeder willkürlichen Stelle in einen Längsträger oder z.B. zwischen zwei schon angeordne ten Längsträgern gelegt werden können. Durch seine Gestaltung kann das Querträgerende 7 nicht in einer horizontalen Position zwischen dem aufstehende Rand 5 und dem ausragenden oberen Flansch 9 des Längsträgers gehakt werden. Wenn der Querträger nur an einem Ende in einen Längsträger gehakt werden soll (siehe Figur 2), dann kann dieses in der Weise nach Figur 5 ausgeführt werden. Nachdem der Querträger an seinem einen Längsende eingehakt ist, wird das andere Ende gemäß Pfeil x hochgefahren. Einmal in einer horizontalen Position geraten ist die Verbindung automatisch gesichert.The cross members must be arranged at any arbitrary position in a longitudinal member or, for example, between two ten side members can be placed. Due to its design, the cross member end 7 cannot be hooked in a horizontal position between the upstanding edge 5 and the protruding upper flange 9 of the side member. If the cross member is only to be hooked into a longitudinal member at one end (see FIG. 2), then this can be carried out in the manner according to FIG. 5. After the cross member is hooked at one longitudinal end, the other end is raised according to arrow x. Once in a horizontal position, the connection is automatically secured.

Wenn der Querträger z.B. zwischen zwei vorhandenen Längsträgern angebracht werden muss, kann nach der Erfindung ein Querträger Verwendung finden, der derart geformt ist, daß dieser in eine um seine Längsachse verdrehte erste Position und in eine horizontale Ebene zwischen den Stegen der beiden nächstliegenden Längsträgern gebracht werden kann (Figur 3, 3a) und danach durch Verdrehung um seine Längsachse zwischen den oberen Flansch 9 und Unterränder 6 gesichert wird. Dazu ist der Querträger 2 an seiner Stirnseite mit einem Sicherungsteil einer z.B. aus der Figur 6 ersichtlichen Form versehen.If the cross member e.g. must be attached between two existing longitudinal beams, according to the invention a cross beam can be used which is shaped such that it can be brought into a first position rotated about its longitudinal axis and in a horizontal plane between the webs of the two nearest longitudinal beams (Figure 3 , 3a) and then secured by rotation about its longitudinal axis between the upper flange 9 and lower edges 6. For this purpose, the cross member 2 is provided with a securing part of a e.g. provided from the figure 6 form.

Die gewählte Lösung weist einen Querträger 13 auf welcher eine Stirnplatte 15 aufweist mit einem rechteckigen Dreiecksform, die eine lange Seite 11 und eine kurze Seite 10 hat. Der Querträger 1 wird bei einer ersten verdrehten Position mit seiner langen Seite 11 über den Rand 6 des Tragflansches 5 des Längsträgers 1 gehakt und durch Verdrehung des Querträgers 2 um seine Längsachse wird die hochgerichtete lange Dreiecksseite 11 den Querträger in den Längsträger 1 zwischen den Rand 6 und den oberen Flansch 9 sichern. In dieser Position hakt die Stirnplatte des Querträgers mit seiner kurzen Rechtecksseite 10 über den Rand hin.The selected solution has a cross member 13 on which an end plate 15 has a rectangular triangular shape, which has a long side 11 and a short side 10. In a first rotated position, the cross member 1 is hooked with its long side 11 over the edge 6 of the supporting flange 5 of the side member 1, and by turning the cross member 2 about its longitudinal axis, the upright long triangular side 11 becomes the cross member in the side member 1 between the edge 6 and secure the upper flange 9. In this position, the end plate of the cross member hooks over the edge with its short rectangular side 10.

Wie in Figur 7 ist dargestellt, kann das Querträgerende mit z.B. einer Bolzenverbindung 16 an den Querträger befestigt werden. Durch jetzt die Position des Querträgers 7 zu verstellen, gerät die obere Seite des Querträgers in eine andere Ebene. Die dargestellte Ausführungsform hat nur einen Verbindungsbolzen 16 wodurch, (durch das Ende 7 um 180° um die Längsachse des Querträgers zu verdrehen) zwischen zwei verschiedenen Ebenen des Querträgers 2 in bezug auf die obere Seite des Längsträgers gewählt werden kann. In Figur 7 ist die Stelle des Verbindungsbolzens 16 derart gewählt daß die obere Fläche des Querträgers 2 in derselben Ebene wie die Oberfläche des Längsträgers 1 liegt. Durch nun den Verbindungsbolzen locker zu drehen und den Querträger 2 um seine Längsachse über einen Winkel von 180° zu verdrehen, wird der Querträger 2b erhalten mit der oberen Seite in einer niedrigeren Ebene als die obere Seite des Querträgers 1. Im Bereich des Querträgers 2a kann die Schalungsplatte auf die Längsträger und Querträger gelegt werden. Mit dem Querträger 2b kann eine Schalungsplatte zwischen die Längsträger gelegt werden, welche Platte eine derartige Stärke aufweist daß die obere Seite der Schalungsplatte in derselben Ebene liegt als die obere Seite des Längsträgers 1, sodaß eine flache Schalungsfläche erhalten wird.As shown in FIG. 7, the cross member end can be fastened to the cross member with, for example, a bolt connection 16. By now adjusting the position of the cross member 7, the upper side of the cross member moves into a different plane. The illustrated Embodiment has only one connecting bolt 16, which (by rotating the end 7 through 180 ° about the longitudinal axis of the cross member) can be chosen between two different planes of the cross member 2 with respect to the upper side of the longitudinal member. In Figure 7, the location of the connecting pin 16 is chosen such that the upper surface of the cross member 2 is in the same plane as the surface of the side member 1. By turning the connecting bolt loosely and turning the cross member 2 about its longitudinal axis through an angle of 180 °, the cross member 2b is obtained with the upper side in a lower plane than the upper side of the cross member 1. In the area of the cross member 2a can the formwork panel is placed on the side members and cross members. With the cross member 2b, a formwork panel can be placed between the longitudinal members, which panel has such a thickness that the upper side of the formwork panel lies in the same plane as the upper side of the longitudinal member 1, so that a flat formwork surface is obtained.

Die Erfindung ist nicht auf nur die Verwendung bei schon parallel zueinander fest angeordneten Längsträgern beschränkt. Sie findet auch Verwendung für das in einen Längsträger Einhaken eines Querträgerendes wobei das andere Ende eines Querträgers nach dem Einhaken des ersten Endes aus einer niedriger liegenden Ebene endgültig auf dieselbe Höhe wie das erste Ende gebracht wird. In der Endposition ist das Querträgerende gleichfalls in dem Längsträger gesichert.The invention is not limited to use only in the case of longitudinal beams which are already firmly arranged parallel to one another. It is also used for hooking a crossmember end into a longitudinal beam, the other end of a crossmember being finally brought to the same height as the first end from a lower level after hooking in the first end. In the end position, the cross member end is also secured in the side member.
