Description

Bei Traggerüsten zur Abstützung von Decken, Arbeitsplattformen, Schalungsteilen im Betonbau oder dergleichen werden häufig Diagonalkreuze zwischen die Rahmenteile des Gerüsts eingesetzt, damit das Gerüst die notwendigen statischen Eigenschaften erhält oder um verschiedene Rahmenteile miteinander zu verbinden.In the case of shoring for supporting ceilings, work platforms, formwork parts in concrete construction or the like, diagonal crosses are often used between the frame parts of the scaffolding so that the scaffolding has the necessary static properties or to connect different frame parts to one another.

Bisher sind zur Befestigung der Diagonalkreuze Einhängevorrichtungen an den Rahmenteilen des Gerüsts angeordnet, die aus jeweils vier von den Rahmenteilen abstehenden Fingern mit einem kipp- oder schwenkbaren Endabschnitt bestehen. An den Enden der Streben der Diagonalkreuze sind dazu Öffnungen vorgesehen, die über die Finger geschoben werden. Anschließend werden die Endabschnitte der vier Finger verschwenkt, sodass die Enden der Streben des Diagonalkreuzes nicht mehr selbsttätig von den Aufnahmefingern heruntergleiten können und das Diagonalkreuz sicher am Gerüst verankert ist.Hitherto, for fastening the diagonal crosses, suspension devices have been arranged on the frame parts of the scaffolding, each consisting of four fingers protruding from the frame parts with a tiltable or pivotable end section. For this purpose, openings are provided at the ends of the struts of the diagonal crosses, which are pushed over the fingers. The end sections of the four fingers are then pivoted so that the ends of the struts of the diagonal cross can no longer automatically slide down from the receiving fingers and the diagonal cross is securely anchored to the framework.

Das gleichzeitige Aufstecken der Öffnungen an den vier Enden der Streben des Diagonalkreuzes auf die Aufnahmefinger ist jedoch schwierig. Außerdem können beim Verschwenken des Endabschnitts eines Aufnahmefingers von Hand andere Enden des Diagonalkreuzes wieder von den Aufnahmefingern gleiten. Daher kann die Montage eines Diagonalkreuzes bisher nicht oder nur erschwert von einer Person allein sicher vorgenommen werden. JP 2005 127036 A offenbart ein Traggerüst mit den Merkmalen des einleitenden Teils des Anspruchs 1.However, it is difficult to fit the openings at the four ends of the struts of the diagonal cross onto the receiving fingers at the same time. In addition, when pivoting the end section of a pick-up finger by hand, other ends of the diagonal cross can slide off the pick-up fingers again. For this reason, the installation of a diagonal cross has hitherto not been possible, or only with great difficulty, by one person alone. JP 2005 127036 A discloses a shoring with the features of the preamble of claim 1.

Zur Vereinfachung der Montage von Diagonalkreuzen schlägt die Erfindung ein Traggerüst gemäß Anspruch 1 vor, mit mindestens einer Einhängevorrichtung für ein das Traggerüst aussteifendes Diagonalkreuz, wobei die Einhängevorrichtung Aufnahmefinger für an den Enden des Diagonalkreuzes vorgesehene Öffnungen aufweist und wobei zwei erste Aufnahmefinger der Einhängevorrichtung jeweils einen festen abgewinkelten Endabschnitt und den ersten Aufnahmefingern gegenüberliegende zweite Aufnahmefinger einen schwenkbaren Endabschnitt aufweisen.In order to simplify the assembly of diagonal crosses, the invention proposes a shoring according to claim 1, with at least one suspension device for a diagonal cross stiffening the shoring, the suspension device Having receiving fingers for openings provided at the ends of the diagonal cross and wherein two first receiving fingers of the suspension device each have a fixed angled end section and the first receiving fingers opposite second receiving fingers have a pivotable end section.

Das Ausstatten von zweien der vier zur Befestigung eines Diagonalkreuzes notwendigen Aufnahmefingern mit festen, abgewinkelten Endabschnitten vereinfacht die Montage eines Diagonalkreuzes erheblich. Dennoch wird die sichere Befestigung des Diagonalkreuzes nicht beeinträchtigt.Equipping two of the four receiving fingers required to attach a diagonal cross with fixed, angled end sections simplifies the assembly of a diagonal cross considerably. Nevertheless, the secure attachment of the diagonal cross is not impaired.

In die ersten Aufnahmefinger mit abgewinkelten Endabschnitten kann jeweils ein Ende der beiden Streben des Diagonalkreuzes mit seiner Öffnung eingehängt werden und die Öffnungen an den anderen Enden der Streben jeweils über einen der zweiten Aufnahmefinger mit schwenkbarem Endabschnitt geschoben werden, bevor die Endabschnitte der zweiten Aufnahmefinger zur Sicherung des Diagonalkreuzes verschwenkt werden. So können zunächst die oberen oder unteren Enden des Diagonalkreuzes in die ersten Aufnahmefinger eingehängt werden. Die abgewinkelten Endabschnitte sorgen dafür, dass die Enden des Kreuzes nicht wieder von den ersten Aufnahmefingern abgleiten, während die gegenüberliegenden Enden der Kreuze auf die zweiten Aufnahmefinger aufgeschoben werden. Auch das anschließende Verschwenken der Endabschnitte der zweiten Finger ist problemlos möglich, ohne dass das Diagonalkreuz wieder von den ersten Aufnahmefingern abgleitet. Damit kann ein Diagonalkreuz ohne Weiteres von einer Person allein montiert werden.One end of the two struts of the diagonal cross can be hung with its opening in the first receiving fingers with angled end sections, and the openings on the other ends of the struts can each be pushed over one of the second receiving fingers with a pivotable end section before the end sections of the second receiving fingers are secured of the diagonal cross can be pivoted. In this way, the upper or lower ends of the diagonal cross can be hooked into the first receiving fingers. The angled end sections ensure that the ends of the cross do not slide off the first pick-up fingers again while the opposite ends of the crosses are pushed onto the second pick-up fingers. The subsequent pivoting of the end sections of the second fingers is also possible without any problems, without the diagonal cross slipping off the first receiving fingers again. This means that a diagonal cross can easily be assembled by one person alone.

Die Öffnungen in den freien Endbereichen der Diagonalkreuze weisen jeweils als Durchbruchsöffnungen einen Durchmesser auf, der kleiner ist als die Erstreckung bzw. Größe der Aufnahmefinger, deren Größe sich aus einem Basisabschnitt und einem Endabschnitt zusammensetzen. Vorzugsweise können die abgewinkelten Endabschnitte der ersten Aufnahmefinger einen Winkel von 20° bis 70° mit einem Basisabschnitt der Aufnahmefinger bilden. Der abgewinkelte Endabschnitt ist mit dem Basisabschnitt, starr, unbeweglich verbunden. Dieser Winkelbereich ermöglicht ein leichtes Einhängen der Diagonalkreuzenden und gleichzeitig eine ausreichende Sicherung der Enden nach dem Einhängen.The openings in the free end areas of the diagonal crosses each have a diameter as breakthrough openings that is smaller than the extension or size of the pick-up fingers, the size of which is composed of a base section and an end section. Preferably, the angled end portions of the first pick-up fingers may form an angle of 20° to 70° with a base portion of the pick-up fingers. The angled end section is rigidly, immovably connected to the base section. This angular range enables the diagonal crossing ends to be easily hooked in and, at the same time, the ends to be sufficiently secured after hooking in.

Die Endabschnitte der zweiten Aufnahmefinger können erfindungsgemäß zwischen einer zu einem Basisabschnitt der zweiten Aufnahmefinger parallelen Stellung und einer zu dem Basisabschnitt im Wesentlichen senkrechten Stellung verschwenkbar sein. In der zum Basisabschnitt parallelen Stellung können die Enden der Diagonalkreuzstreben leicht auf die zweiten Aufnahmefinger aufgeschoben werden. Nach dem Verschwenken der Endabschnitte in die 90°-Position ist das Diagonalkreuz am Gerüst gesichert.According to the invention, the end sections of the second pick-up fingers can be pivotable between a position parallel to a base section of the second pick-up fingers and a position essentially perpendicular to the base section. In the position parallel to the base section, the ends of the diagonal cross braces can be easily pushed onto the second receiving fingers. After pivoting the end sections into the 90° position, the diagonal cross is secured to the scaffolding.

Erfindungsgemäß sind die Endabschnitte der zweiten Aufnahmefinger in den beiden Endstellungen über einen Rastmechanismus der zweiten Aufnahmefinger arretierbar. Beim Aufschieben der Diagonalkreuzenden auf die zweiten Aufnahmefinger kann dadurch ein ungewolltes Verstellen der Endabschnitte der Finger, was das Aufschieben behindern könnte, vermieden werden. Auch ein unbeabsichtigtes Lösen der Verriegelung des Diagonalkreuzes wird durch eine solche Arretierung erschwert.According to the invention, the end sections of the second receiving fingers can be locked in the two end positions via a locking mechanism of the second receiving fingers. When the diagonal crossing ends are slid onto the second receiving fingers, an unintentional adjustment of the end sections of the fingers, which could impede the sliding, can thereby be avoided. Unintentional release of the locking of the diagonal cross is made more difficult by such a locking.

Die Endabschnitte der ersten und zweiten Aufnahmefinger verjüngen sich erfindungsgemäß nach außen hin konisch, um das Aufschieben der Diagonalkreuzenden zu erleichtern.According to the invention, the end portions of the first and second pick-up fingers are tapered tapered outwards to make it easier to slide on the diagonal crossing ends.

Bei einer bevorzugten Ausführungsform des Traggerüsts kann dieses aus mehreren Rahmen zusammensetzbar sein, die jeweils mit mindestens einer Einhängevorrichtung für ein Diagonalkreuz versehen sind. Durch Verbinden mehrerer dieser Rahmen, die auch eine unterschiedliche Größe aufweisen können, kann das Traggerüst dem Einsatzzweck angepasst werden, wobei Diagonalkreuze an jedem Rahmen montiert werden können, an dem dies erforderlich ist. Es können auch jeweils zwei Rahmen durch ein Diagonalkreuz miteinander verbunden werden. Dabei ist es weiter von Vorteil, wenn die ersten und zweiten Aufnahmefinger der Einhängevorrichtung jeweils in den Eckbereichen eines Rahmens angeordnet sind. Dadurch können die Diagonalkreuze die beste Stützkraft auf die Rahmen ausüben.In a preferred embodiment of the supporting structure, it can be composed of several frames, each of which is provided with at least one suspension device for a diagonal cross. By connecting several of these frames, which can also be of different sizes, the shoring can be adapted to the intended use, with diagonal crosses being able to be mounted on each frame where this is required. Two frames can also be connected to each other with a diagonal cross. It is also advantageous if the first and second receiving fingers of the suspension device are each arranged in the corner regions of a frame. This allows the diagonal crosses to exert the best supporting force on the frames.

Die Rahmen können auch um 180° gedreht zusammengefügt oder zusammengesteckt werden. Werden die Rahmen um 180° gedreht, so befinden sich die Aufnahmefinger mit einem starren abgewinkelten Endabschnitt oben und die Aufnahmefinger mit einem beweglichen, schwenkbaren Endabschnitt unten. Schnell und mit erhöhter Sicherheit können die das Traggerüst aussteifende Diagonalkreuze zuerst oben eingefädelt und eingehängt werden und danach werden die unteren Öffnungen im Bereich der freien Enden der Diagonalkreuze in die unteren Aufnahmefinger mit den beweglichen Endabschnitten eingeschwenkt und dort über die beweglichen Endabschnitte lagegesichert. Die Endabschnitte werden dazu in eine Position verschwenkt, die die Öffnungen der Diagonalkreuze überdeckt und ein Abziehen der Diagonalkreuze von diesen Aufnahmefingern sicher verhindert. Im Folgenden wird ein bevorzugtes Ausführungsbeispiel eines Rahmens eines erfindungsgemäßen Traggerüsts mit Bezug auf die Zeichnung näher beschrieben. Dabei wird in keiner der Figuren die Rastvorrichtung des Anspruchs 1 explizit dargestellt.The frames can also be rotated by 180° and assembled or plugged together. If the frames are rotated 180°, the pick-up fingers with a rigid angled end section are at the top and the pick-up fingers with a movable, pivoting end section are at the bottom. The diagonal crosses stiffening the shoring can first be threaded in and hooked in quickly and with increased safety and then the lower openings in the area of the free ends of the diagonal crosses are pivoted into the lower receiving fingers with the movable end sections and secured in position there via the movable end sections. For this purpose, the end sections are pivoted into a position which covers the openings of the diagonal crosses and reliably prevents the diagonal crosses from being pulled off these receiving fingers. A preferred embodiment of a frame of a shoring according to the invention is described in more detail below with reference to the drawing. The locking device of claim 1 is not explicitly shown in any of the figures.

a partial section in the construction of a shoring with a frame shown in sections, which has pick-up fingers with rigid angled end sections at the top and pick-up fingers with movable end sections at the bottom.

Fig. 1 zeigt eine schematische Ansicht eines Rahmens 10 eines hier nicht weiter dargestellten Traggerüsts, das aus einer Vielzahl von Rahmen 10 aber auch anderer, beispielsweise höherer Rahmen zusammengesetzt werden kann. 1 shows a schematic view of a frame 10 of a shoring not shown here, which consists of a plurality of frames 10 but other, for example, higher frame can be assembled.

Der Rahmen 10 weist zwei Seitenrohre 12, 14 auf, die durch zwei Querrohre 16, 18 miteinander verbunden sind. Die Seitenrohre 12, 14 können an ihren Enden mit Rohren weiterer Rahmen 10 verschraubt werden (nicht gezeigt) und/oder zusammengesteckt werden.The frame 10 has two side tubes 12,14 which are connected to one another by two cross tubes 16,18. The side tubes 12, 14 can be screwed at their ends to tubes of other frames 10 (not shown) and/or plugged together.

Außerdem sind an den Seitenrohren 12, 14 in deren unterem Bereich erste Aufnahmefinger 20, 22 und in einem oberen Bereich zweite Aufnahmefinger 24, 26 zur Befestigung eines Diagonalkreuzes (nicht gezeigt) angebracht. In diese Aufnahmefinger 20 bis 26 können die mit Öffnungen versehenen vier Enden eines Diagonalkreuzes eingehängt werden. Zunächst werden dazu die unteren Enden des Diagonalkreuzes in die ersten Aufnahmefinger 20, 22 eingefädelt und eingehängt und dann werden die oberen Enden des Diagonalkreuzes auf die zweiten Aufnahmefinger 24, 26 aufgeschoben. Anschließend wird das Diagonalkreuz an den Aufnahmefindern 24, 26 lagegesichert. Eine Lagesicherung wird mit Bezug auf die Fig. 2 und 3 näher beschrieben.In addition, first receiving fingers 20, 22 and in an upper area second receiving fingers 24, 26 for attaching a diagonal cross (not shown) are attached to the side pipes 12, 14 in the lower area. The four ends of a diagonal cross, which are provided with openings, can be hooked into these receiving fingers 20 to 26 . For this purpose, the lower ends of the diagonal cross are first threaded into the first receiving fingers 20, 22 and hooked in, and then the upper ends of the diagonal cross are pushed onto the second receiving fingers 24, 26. The diagonal cross is then secured in position on the recording finders 24, 26. A location backup is made with reference to the 2 and 3 described in more detail.

Fig. 2 zeigt eine vergrößerte Detaildarstellung des ersten Aufnahmefingers 20. Dieser weist einen Endabschnitt 20.1 auf, der gegenüber einem Basisabschnitt 20.2 nach unten, starr verlaufend abgewinkelt ist. Dadurch kann eine Öffnung im unteren Ende einer der Streben eines Diagonalkreuzes von unten über den Endabschnitt 20.1 eingehängt und am Basisabschnitt 20.2 gehalten werden. Durch die abgewinkelte Form des Endabschnitts 20.1 kann ein ungewolltes Aushängen der Strebe verhindert werden, wenn eine leichte Kraft nach oben auf das Diagonalkreuz ausgeübt wird. Gleichzeitig oder zeitlich versetzt wie das Einhängen der ersten Strebe erfolgt das Einhängen des unteren Endes der zweiten Strebe des Diagonalkreuzes auf den Aufnahmefinger 22. 2 shows an enlarged detail view of the first pick-up finger 20. This has an end section 20.1, which is angled downwards, running rigidly, in relation to a base section 20.2. As a result, an opening in the lower end of one of the struts of a diagonal cross can be hung from below over the end section 20.1 and held on the base section 20.2. The angled shape of the end section 20.1 can prevent the strut from unintentionally detaching if a slight upward force is exerted on the diagonal cross. Simultaneously or the lower end of the second strut of the diagonal cross is hung onto the receiving finger 22 at a different time than the first strut was hooked in.

Anschließend können die oberen Enden der Streben des Diagonalkreuzes auf die zweiten Aufnahmefinger 24, 26 aufgeschoben werden. Die Ausgestaltung der zweiten Finger 24, 26 wird am Beispiel des Fingers 24 in Fig. 3 verdeutlicht. Der Aufnahmefinger 24 weist einen Endabschnitt 24.1 auf, der gelenkig an einem Basisabschnitt 24.2 gelagert ist. Dadurch lässt sich der Endabschnitt 24.1 aus einer zum Basisabschnitt 24.2 parallelen Stellung in die dargestellte um 90° abgewinkelte Stellung bringen. Wenn der Endabschnitt 24.1 parallel zum Basisabschnitt 24.2 ausgerichtet ist, bilden beide Abschnitte einen langen Finger, auf den das obere Ende einer der Streben eines Diagonalkreuzes mit einer Öffnung aufgeschoben werden kann. Anschließend wird der Endabschnitt 24.1 in die 90°-Stellung verschwenkt und dadurch die Strebe im Aufnahmefinger 24 verriegelt. In gleicher Weise wird das obere Ende der zweiten Strebe des Diagonalkreuzes auf den Aufnahmefinger 26 aufgeschoben und durch diesen verriegelt. Durch die Verriegelung steht der Endabschnitt 24.1 über den Durchmesser der Öffnung hinaus. In anderen Worten, der Endabschnitt überragt die Öffnung und versperrt das Abziehen des Diagonalkreuzes von den Aufnahmefingern 24, 26.The upper ends of the struts of the diagonal cross can then be pushed onto the second receiving fingers 24, 26. The configuration of the second fingers 24, 26 is illustrated using the example of finger 24 in 3 clarified. The pick-up finger 24 has an end section 24.1 which is articulated to a base section 24.2. As a result, the end section 24.1 can be brought from a position parallel to the base section 24.2 into the position shown at an angle of 90°. When the end section 24.1 is aligned parallel to the base section 24.2, both sections form a long finger onto which the upper end of one of the struts of a diagonal cross with an opening can be pushed. The end section 24.1 is then pivoted into the 90° position, thereby locking the strut in the receiving finger 24. In the same way, the upper end of the second strut of the diagonal cross is pushed onto the receiving finger 26 and locked by it. Due to the locking, the end section 24.1 protrudes beyond the diameter of the opening. In other words, the end portion overhangs the opening and blocks withdrawal of the diagonal cross from the pickup fingers 24, 26.

Die in Fig. 1 gezeigte Rahmenkonstruktion mit ersten und zweiten Aufnahmefingern 20 bis 26 ermöglicht es, ein Diagonalkreuz durch nur eine Person am Rahmen 10 zu befestigen. Außerdem ist der Befestigungsprozess des Diagonalkreuzes deutlich einfacher und schneller als bei Rahmen nach dem Stand der Technik mit vier verriegelbaren, beweglichen Aufnahmefingern. Das Aufschieben bzw. Einhängen der Enden des Diagonalkreuzes wird zudem dadurch erleichtert, dass sich die Endabschnitte 20.1, 24.1 der Aufnahmefinger 20 bis 26 zu den Enden hin konisch verjüngen.In the 1 The frame construction shown with first and second receiving fingers 20 to 26 makes it possible to attach a diagonal cross to the frame 10 by just one person. In addition, the process of attaching the diagonal cross is significantly easier and faster than prior art frames with four lockable, movable pick-up fingers. Pushing on or hanging in the ends of the diagonal cross is also made easier in that the end sections 20.1, 24.1 of the receiving fingers 20 to 26 taper conically towards the ends.

Figur 4 zeigt Teile eines Traggerüsts 40, im Aufbau befindlich, das im gezeigten Aufbaustadium aus vier Rahmen 10 zusammengesetzt ist. Die vier Rahmen 10 sind auf einer Seite schon mit einem ersten Diagonalkreuz 42 ausgesteift, das an seinen freien Enden Öffnungen 43 aufweist. Das erste Diagonalkreuz 42 ist über in der Figur 4 nicht gezeigte Aufnahmefinger 20, 22 mit starren Endabschnitten aufgesteckt und in Aufnahmefingern 24 und 26, wie in Figur 1 gezeigt, ebenfalls aufgesteckt und über die beweglichen Endabschnitte gesichert. Die aufgesteckten Rahmen 10 sind über ein zweites Diagonalkreuz 44 miteinander verbunden, indem die Öffnungen 43 des zweiten Diagonalkreuzes 44 auf die Aufnahmefinger 20, 24 aufgesteckt sind. Den gezeigten ersten und zweiten Diagonalkreuzen 42, 44 gegenüberliegend (nicht in der Figur gezeigt) werden ebenfalls zwei Diagonalkreuze nachfolgend eingebaut, damit das Traggerüst 40 belastungsstabil ausgesteift ist. figure 4 shows parts of a shoring 40 under construction, which is composed of four frames 10 in the construction stage shown. The four frames 10 are already reinforced on one side with a first diagonal cross 42, which has openings 43 at its free ends. The first diagonal cross 42 is over in the figure 4 pick-up fingers 20, 22, not shown, attached with rigid end sections and in pick-up fingers 24 and 26, as in figure 1 shown, also attached and secured via the movable end sections. The attached frames 10 are connected to one another via a second diagonal cross 44 in that the openings 43 of the second diagonal cross 44 are slipped onto the receiving fingers 20, 24. The shown first and second diagonal crosses 42, 44 opposite (not shown in the figure), two diagonal crosses are also installed below, so that the shoring 40 is reinforced load-resistant.

Figur 5 zeigt eine Ausschnittsvergrößerung eines Rahmens 10 mit einem Seitenrohr 12 des Rahmens 10, ebenfalls im Ausschnitt. Am Seitenrohr 12 ist der Aufnahmefinger 20 fest angebracht. Er setzt sich aus einem Basisabschnitt 20.2 und einem Endabschnitt 20.1 zusammen. Der Endabschnitt 20.1 ist abgewinkelt, vorzugsweise in einer Abwinkelung zwischen 20° und 70° am Basisabschnitt 20.2 angeformt. Das freie Ende des ersten Diagonalkreuzes 42 mit der Öffnung 43 wird über den starren abgewinkelten Endabschnitt 20.1 auf den Basisabschnitt 20.2 aufgefädelt. Am gegenüberliegenden Ende einer Strebe des ersten Diagonalkreuzes 42 ist ebenfalls eine Öffnung 43 ausgebildet, die auf einen Aufnahmefinger mit beweglichem Endabschnitt aufgeschoben wird. figure 5 shows an enlarged detail of a frame 10 with a side tube 12 of the frame 10, also in detail. The pick-up finger 20 is firmly attached to the side pipe 12 . It consists of a base section 20.2 and an end section 20.1. The end section 20.1 is angled, preferably formed at an angle between 20° and 70° on the base section 20.2. The free end of the first diagonal cross 42 with the opening 43 is threaded over the rigid angled end section 20.1 onto the base section 20.2. At the opposite end of a strut of the first diagonal cross 42 there is also an opening 43 which is pushed onto a receiving finger with a movable end section.

Figur 6 zeigt einen Teilausschnitt im Aufbau eines Traggerüsts mit einem Rahmen 10, der die Aufnahmefinger 20, 24 zeigt. Die Aufnahmefinger 20 mit abgewinkelten Endabschnitten sind am Rahmen im unteren Bereich ausgebildet und die Aufnahmefinger 24 mit beweglichen Endabschnitten 24.1 sind im oberen Bereich des Rahmens 10 befestigt. Die Aufnahmefinger 20, 24 sind am Seitenrohr 12 ausgebildet und dort befestigt. In der Figur 6 ist gezeigt, wie ein Arbeiter 50 ein erstes Diagonalkreuz 42 auf den Rahmen 10 mit den erfindungsgemäßen Aufnahmefingern 20, 24 aufsetzt. Das erste Diagonalkreuz 42 mit den Öffnungen 43 wird zuerst schräghaltend über die in der Figur nicht gezeigten starren Endabschnitte des Aufnahmefingers 20 auf den Basisabschnitt 20.2 aufgefädelt. Ist das erste Diagonalkreuz 42 mit seinen freien Enden auf beiden Aufnahmefingern 20 aufgefädelt, so kann es in die Aufnahmefinger 24 mit den beweglichen Endabschnitten 24.1 aufgesteckt werden. Die freien Enden des ersten Diagonalkreuzes 42 mit den Öffnungen 43 werden auf den jeweiligen Basisabschnitt 24.2 aufgeschoben und anschließend wird der bewegliche Endabschnitt 24.1 so verschwenkt, dass er die Öffnungen 43 überragt und die positionierte Stellung des ersten Diagonalkreuzes 42 absichert. Mit der gezeigten Ausgestaltung von Aufnahmefingern 20, 24 an dem Rahmen 10 kann ein Arbeiter 50 das erste Diagonalkreuz 42 und weitere Diagonalkreuze sicher ohne weitere Hilfestellungen von weiteren Personen an Rahmen für ein Traggerüst anbringen. figure 6 shows a partial detail in the structure of a support structure with a frame 10, which shows the receiving fingers 20, 24. The pickup fingers 20 with angled end sections are formed on the frame in the lower area and the receiving fingers 24 with movable end sections 24.1 are fixed in the upper area of the frame 10. The pickup fingers 20, 24 are formed on the side tube 12 and secured there. In the figure 6 1 is shown how a worker 50 places a first diagonal cross 42 on the frame 10 with the receiving fingers 20, 24 according to the invention. The first diagonal cross 42 with the openings 43 is first threaded onto the base section 20.2, holding it at an angle, over the rigid end sections of the receiving finger 20, which are not shown in the figure. If the first diagonal cross 42 is threaded onto both receiving fingers 20 with its free ends, it can be plugged into the receiving fingers 24 with the movable end sections 24.1. The free ends of the first diagonal cross 42 with the openings 43 are pushed onto the respective base section 24.2 and then the movable end section 24.1 is pivoted in such a way that it protrudes beyond the openings 43 and secures the position of the first diagonal cross 42. With the configuration of receiving fingers 20, 24 on the frame 10 shown, a worker 50 can securely attach the first diagonal cross 42 and further diagonal crosses to frames for a shoring without further assistance from other people.
