Abstract

The frame has upright supports (2) and cross beams (10), which are attached with their ends to the supports. A positively formed fixture is provided between the supports and the beams by an elevatable part of the support-beam connection, which provides against movement in all three spatial planes. The supports are free from lateral protrusions beyond their outer boundary at the point of connection. The fixture is formed by the engagement of a protruding element (68) from the beam into openings (18) in the support. The protruding element can be shifted to and fro in a direction corresponding to the longitudinal direction of the beam.

Description

Die Erfindung bezieht sich auf ein Gerüst, insbesondere für eine Plattform oder eine Bühne oder eine Deckenschalung, aufweisend:

  • (a) aufrechte Steher;
  • (b) und Traversen, die als versteifende Querverbindungen mit ihren Enden an den betreffenden Stehern befestigt sind.
    • The invention relates to a scaffolding, in particular for a platform or a stage or a ceiling formwork, comprising:
  • (a) upright posture;
  • (b) and trusses, which are attached as stiffening cross connections with their ends to the relevant uprights.

    • Gerüste sind in zahlreichen Ausführungsformen bekannt. So ist es aus dem Bereich der Schalungen für Decken in größerer Höhe (auch Deckenschalungstische genannt) zum Beispiel bekannt, als versteifende Querverbindungen Traversen vorzusehen, die mit in Längsnuten des Stehers greifenden Klemmklauen an dem betreffenden Steher befestigt werden. Diese Art der Befestigung ist gegenüber Kräften in Längsrichtung des Stehers nicht formschlüssig. Auf dem Gebiet der Fassadengerüste ist es zum Beispiel bekannt, Steher mit tellerartigen, angeschweißten Querauskragungen zu versehen, an denen Traversen befestigt werden können. Diese Art der Befestigung setzt das Vorhandensein der Querauskragungen voraus, die aufwendig an die Steher angeschweißt werden müssen. Scaffolds are known in numerous embodiments. So it is from the area the formwork for ceilings at a higher height (also slab formwork tables known), for example, known as stiffening cross-ties to be provided with the clamping claws which grip in the longitudinal grooves of the upright be attached to the relevant post. This type of attachment is not positive against forces in the longitudinal direction of the post. On the For example, it is known in the field of facade scaffolding, posts with plate-like, to provide welded cross-overhangs to which crossbars are attached can be. This type of attachment presupposes the presence of the Cross overhangs ahead, which are laboriously welded to the uprights have to.

    Der Erfindung liegt die Aufgabe zugrunde, ein Gerüst der eingangs genannten Art zu schaffen, das sich durch hohe Stabilität und Belastbarkeit in Kombination mit besonders rationeller Herstellbarkeit auszeichnet.The invention has for its object a framework of the aforementioned Art to create that in combination with high stability and resilience with particularly rational manufacturability.

    Diese Aufgabe wird durch ein Gerüst gemäß Anspruch 1 gelöst.This object is achieved by a scaffold according to claim 1.

    Ein Gerüst mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus GB-A-2 262 562 bekannt. GB-A-2 262 562 und auch DE 36 41 349 A zeigen Gerüste, bei denen keine formschlüssige Verbindung zwischen Steher und Traverse in Längsrichtung-des Stehers vorgesehen ist.A scaffold with the features of the preamble of claim 1 is from GB-A-2 262 562 known. GB-A-2 262 562 and also DE 36 41 349 A show scaffolding in which there is no positive connection Connection between upright and traverse in the longitudinal direction of the upright is provided.

    WO 83/03868 zeigt ein Gerüst, bei dem die Verbindung zwischen Steher und Traverse auch in Längsrichtung des Stehers formschlüssig ist. Die formschlüssige Verbindung wird jedoch mit anderen Mitteln als bei der vorliegenden Erfindung erzielt.WO 83/03868 shows a scaffold in which the connection between the upright and the crossbar also in the longitudinal direction of the post is form-fitting. However, the positive connection is achieved by other means than in the present invention.

    Das erfindungsgemäße Gerüst hat eine umfassende, formschlüssige Festlegung der betreffenden Traverse an dem betreffenden Steher, ohne daß eine mit Aufwand zu fertigende Querauskragung vorgesehen wäre. Die formschlüssige Festlegung speziell auch in Längsrichtung des betreffenden Stehers führt dazu, daß die Traversen auch in Vertikalrichtung hoch belastbar sind, ohne ein Sicherheitsrisiko einzugehen.The scaffold according to the invention has a comprehensive, form-fitting definition of the crossbar in question on the post in question, without a cross projection would be provided with effort. The form-fitting Specification also leads in particular in the longitudinal direction of the upright in question to the fact that the trusses are also highly resilient in the vertical direction, without a Take security risk.

    Es wird darauf hingewiesen, daß die Ausdrucksweise "gegenüber Kräften in Längsrichtung des Stehers sowie dazu rechtwinkligen Richtungen" bzw. "gegenüber Kräften aller drei Raumrichtungen" nicht die Momente um die drei Raumachsen einschließt. Das weiter unten genauer beschriebene Ausführungsbeispiel wird z.B. zeigen, daß gegenüber Drehmomenten um die Längsachse der betreffenden Traverse keine formschlüssige Festlegung vorhanden ist. Wenn ein Gerüst die erfindungsgemäße, formschlüssige Festlegung gegenüber Kräften aller drei Raumrichtungen besitzt, ist formschlüssige Festlegung gegenüber Momentenbelastungen um die drei Raumachsen nicht mehr von primärer Wichtigkeit. Andererseits ist es durchaus möglich, das erfindungsgemäße Gerüst auch mit formschlüssiger Festlegung gegenüber Momenten um eine, zwei oder drei Raumachsen auszustatten.It is pointed out that the expression "against forces in Longitudinal direction of the upright and directions "or" opposite to it at right angles Forces of all three spatial directions "not the moments around the three Includes spatial axes. The embodiment described in more detail below e.g. show that compared to torques about the longitudinal axis there is no form-fitting determination of the traverse in question. If a scaffold compared to the positive locking according to the invention Possessing forces in all three spatial directions is opposed to form-fitting determination Torque loads around the three spatial axes are no longer primary Importance. On the other hand, it is quite possible to use the scaffold according to the invention also with a positive definition of moments by one or two or equip three spatial axes.

    Ferner wird darauf hingewiesen, daß der Begriff "Traverse" auch eine Anordnung von zwei oder mehr Horizontalstreben übereinander, die durch Verbindungsstreben miteinander verbunden sind, umfaßt; derartige Anordnungen werden normalerweise Rahmen genannt, die als versteifende Querverbindungen zwischen Stehern eingebaut werden können.It is also noted that the term "traverse" is also an arrangement of two or more horizontal struts one above the other, which are connected by connecting struts are interconnected, includes; such arrangements are usually called frames that act as stiffening cross connections can be installed between stands.

    Die formschlüssige Festlegung gegenüber Kräften in Längsrichtung des betreffenden Stehers ist durch den Eingriff eines Vorstehelements in eine Öffnung gebildet, wobei das Vorstehelement an dem betreffenden Traversenende vorsteht und die Öffnung an dem betreffenden Steher ausgebildet ist oder umgekehrt. Die erstgenannte dieser beiden Möglichkeiten ist besonders bevorzugt, weil man - das gesamte Gerüst betrachtet - zahlreichere Eingriffsmittel an den Stehern als an den Traversenenden hat und weil gerade bei den Stehern Öffnungen besonders leicht herstellbar sind.The form-fitting determination of forces in the longitudinal direction of the concerned Standing is due to the engagement of a protruding element in an opening formed, the protruding element protruding at the relevant end of the truss and the opening is formed on the relevant post or vice versa. The former of these two options is particularly preferred because - looking at the entire scaffolding - more numerous means of intervention on the Stand than at the end of the truss and because of the openings in the stand are particularly easy to manufacture.

    Vorzugsweise ist eine Längsreihe von Vorstehelementen oder von Öffnungen längs mindestens eines Teils des Stehers vorgesehen, um einen Traversenanschluß an wählbarer Stelle der Höhe vornehmen zu können. Besonders günstig ist es, wenn die Vorstehelemente bzw. Öffnungen in einem Rastermaßabstand vorgesehen sind; außerdem kann man günstig vorsehen, daß es sich um Öffnungen handelt, die auch für die Festlegung von zwei teleskopisch verstellbaren Steherteilen eine Funktion haben.A longitudinal row of protruding elements or of openings is preferred provided along at least part of the post to a truss connection to be able to make at a selectable point in height. Very cheap it is when the protruding elements or openings are spaced apart by a grid are provided; you can also provide cheaply that there are openings acts that also for the setting of two telescopically adjustable Upright parts have a function.

    Vorzugsweise ist das Vorstehelement oder ein die Öffnung aufweisendes Element in einer Richtung hin und her verlagerbar, die im wesentlichen der Traversenlängsrichtung entspricht. Aufgrund dieser Maßnahme kann man die betreffende Traverse besonders umproblematisch zwischen zwei quer zu verbindende Steher einbringen, indem z.B. die beiden Vorstehelemente an den beiden Traversenenden eingefahren werden, so daß die Traverse mit der so etwas verkürzten Länge gerade zwischen die zwei Steher hineinpaßt. Dann kann man z.B. die beiden Vorsteheiemente in Traversenlängsrichtung ausfahren und in die passenden Öffnungen in den beiden Stehern einsetzen. Es wird allerdings darauf hingewiesen, daß es auch Lösungen ohne derartige Verlagerbarkeit der Vorstehelemente oder der die Öffnung aufweisenden Elemente gibt, z.B. ein horizontales Quereinbringen der Traverse, wobei sich die Vorstehelemente in schlitzartige Steheröffnungen hineinbewegen.The projecting element or an element having the opening is preferably Can be moved back and forth in a direction that is essentially the longitudinal direction of the truss equivalent. Because of this measure, one can take the Traverse particularly problematic between two cross to be connected Bring upright, e.g. the two protruding elements on the two Truss ends are retracted so that the truss shortened with something Length fits straight between the two uprights. Then you can e.g. Extend the two extensions in the longitudinal direction of the truss and into the insert suitable openings in the two uprights. However, it will be on noted that there are also solutions without such relocability Protruding elements or the elements having the opening, e.g. on horizontal transverse insertion of the traverse, with the projecting elements in move slot-like standing openings.

    Für die formschlüssige Festlegung zwischen dem betreffenden Steher und dem betreffenden Traversenende gegenüber Kräften in zu der Längsrichtung des betreffenden Stehers rechtwinkligen Richtungen ist ein Eingriff zwischen einem Eingriffsteil an dem betreffenden Traversenende und einer hinterschnittenen Längsvertiefung oder einem hinterschnittenen Längsvorsprung des betreffenden Stehers vorgesehen. Diese Art der formschlüssigen Festlegung hat den Vorteil, daß sie sich unkompliziert erstellen und bei der Demontage des Gerüsts lösen läßt. For the positive determination between the relevant post and the relevant truss end against forces in to the longitudinal direction of the relevant Standing right-angled directions is an interference between one Intervention part at the relevant truss end and an undercut Longitudinal recess or an undercut longitudinal protrusion of the concerned Provided. This type of positive definition has the Advantage that they can be created easily and when dismantling the scaffolding can be solved.

    Vorzugsweise ist das im letzten Absatz beschriebene Eingriffsteil im wesentlichen in Traversenlängsrichtung hin und her verlagerbar. Hier gelten ganz analoge Gesichtspunkte, insbesondere hinsichtlich Einbringbarkeit der betreffenden Traverse zwischen zwei zu verbindende Steher, wie sie weiter vorn im Zusammenhang mit dem Vorstehelement oder dem die Öffnung aufweisenden Element beschrieben worden sind.Preferably, the engaging part described in the last paragraph is essentially Can be moved back and forth in the longitudinal direction of the truss. The same applies here Aspects, especially with regard to the collectibility of the relevant Traverse between two uprights to be connected, as they are related in the foregoing with the protruding element or with the opening Element have been described.

    Wegen der Einfachheit der Ausführung ist vorgesehen, daß im Bereich des betreffenden Traversenendes ein Bolzen angeordnet ist, der sich in Längsrichtung der-betreffenden Traverse erstreckt und um seine Längsachse drehbar ist und einen Bolzenkopf aufweist, der in einer ersten Querrichtung schmaler ist als. in einer zweiten Querrichtung, sodaß der Bolzenkopf in einer ersten Drehposition in die Längsvertiefung einbringbar ist und in einer zweiten Drehposition gegen Herausziehen in Traversenlängsrichtung festgelegt ist. Aufgrund dieser Ausbildung gestaltet sich die Erstellung der formschlüssigen Festlegung gegenüber Kräften in zu der Längsrichtung des betreffenden Stehers rechtwinkligen Richtungen besonders einfach. Vorzugsweise hat man über den Umfang des Stehers verteilt mehrere hinterschnittene Längsvertiefungen oder hinterschnittene Längsvorsprünge, insbesondere vier.Because of the simplicity of execution it is provided that in the area of the concerned Traverse end a bolt is arranged, which extends in the longitudinal direction the crossbar in question extends and is rotatable about its longitudinal axis and has a bolt head which is narrower than in a first transverse direction. in a second transverse direction so that the bolt head in a first rotational position can be introduced into the longitudinal recess and against in a second rotational position Pulling out in the longitudinal direction of the truss is fixed. Because of this training is the creation of the form-fitting definition Forces in directions perpendicular to the longitudinal direction of the post in question particularly easy. One preferably has the circumference of the post distributes several undercut longitudinal recesses or undercut Longitudinal projections, especially four.

    Das Vorstehelement oder die Öffnung ist im Endbereich des Eingriffsteils ausgebildet. Aufgrund dieser Ausbildung kann man durch Manipulation allein des Eingriffsteils die günstige Verlagerung des Vorstehelements bzw. des die Öffnung aufweisenden Elements und des Eingriffsteils in Traversenlängsrichtung bewerkstelligen und außerdem die formschlüssige Festlegung gegenüber Kräften aller drei Raumrichtungen bewerkstelligen. Alternativ ist es allerdings möglich, das dem Traversenende zugeordnete Vorstehelement bzw. Öffnung an von dem Bolzen beabstandeter Position vorzusehen und nicht in den Bolzen zu integrieren.The projecting element or the opening is formed in the end region of the engagement part. Because of this training, you can manipulate the Engagement part, the favorable displacement of the protruding element or the opening having element and the engaging part in the longitudinal direction of the truss accomplish and also the positive determination against forces manage all three spatial directions. Alternatively, it is possible the projecting element or opening assigned to the end of the truss away from the bolt and not in the bolt integrate.

    Vorzugsweise ist dem Eingriffsteil ein Querelement zugeordnet, mit dem das Eingriffsteil in seiner Längsrichtung verlagerbar und um seine Längsachse drehbar ist. Dieses Querelement erlaubt somit ein bequemes Manipulieren des Eingriffsteils.A cross element is preferably assigned to the engagement part, with which the Engagement part displaceable in its longitudinal direction and rotatable about its longitudinal axis is. This cross member thus allows easy manipulation of the engagement part.

    Vorzugsweise weist der Bolzen eine längliche Durchgangsöffnung auf und ist ein die Durchgangsöffnung durchsetzendes Keilelement vorgesehen, durch dessen Bewegung der Bolzenkopf in der hinterschnittenen Längsvertiefung festklemmbar ist. Außerdem ist der Bolzen vorzugsweise in dem Zustand-ohne Keilkraftaufbringung mittels des Keilelements um seine Längsachse drehbar. Das Keilelement erfüllt somit eine Doppelfunktion, indem der Bolzen zunächst ohne Erzeugung einer Keilkraft um seine Achse gedreht wird und dann mittels Keilkraft in Richtung von dem betreffenden Steher fortgezogen wird. Bei entsprechender Ausbildung kann als dritte Funktion hinzukommen, daß man mittels des Keilelements den Bolzen in Längsrichtung hin und her verlagern kann. Schließlich kann bei entsprechender Ausbildung als vierte Funktion hinzukommen, daß man durch Längsverlagerung des Bolzens mittels des Keilelements zugleich auch das an dem Bolzen vorgesehene Vorstehelement in Eingriff mit der gewünschten Öffnung des Stehers bringen kann.The bolt preferably has and is an elongated through opening a wedge element penetrating the through opening is provided by the movement of the bolt head in the undercut longitudinal recess can be clamped. In addition, the bolt is preferably in the state without Wedge force application rotatable about its longitudinal axis by means of the wedge element. The wedge element thus fulfills a double function, in that the bolt first is rotated about its axis without generating a wedge force and then by means of Wedge force is pulled in the direction of the relevant post. With appropriate Training can be added as a third function, that one by means of of the wedge element can move the bolt back and forth in the longitudinal direction. Finally, with appropriate training, a fourth function can be added that one by longitudinal displacement of the bolt by means of the wedge element at the same time that on the bolt provided projection element in engagement with the desired opening of the stand can bring.

    Vorzugsweise ist der betreffende Steher unter Verwendung von Stahlblech-Hohlprofil aufgebaut. Derartige Steher lassen sich preisgünstiger fertigen als aus Aluminium und sind bei guter Querschnittsgestaltung und guter Materialausnutzung nicht unbedingt schwerer als Aluminiumsteher.Preferably, the post in question is using Steel sheet hollow profile built. Such uprights can be Manufacture cheaper than aluminum and are good Cross-sectional design and good material utilization are not essential heavier than aluminum stands.

    Vorzugsweise weist der betreffende Steher mindestens auf einem Teil seiner Länge einen im wesentlichen quadratischen Querschnitt mit vier hinterschnittenen Längsvertiefungen auf.The post in question preferably has at least one part its length has a substantially square cross section with four undercut longitudinal recesses.

    Vorzugsweise weist der betreffende Steher mindestens zwei Teile auf, die teleskopisch relativ zueinander verstellbar sind. Auf diese Weise kann man sich unterschiedliche Steherlängen einstellen. Bei den Stehern können ferner weitere, übliche Bestandteile vorhanden sein, wie Kopfplatte, Fußteil, Spindel-Höhenverstelleinrichtung zur Feineinstellung.The post in question preferably has at least two parts, which are telescopically adjustable relative to each other. In this way you can adjust different post lengths. With the standers further, conventional components may also be present, such as Head plate, foot section, spindle height adjustment device for Fine adjustment.

    Vorzugsweise hat der innere Steherteil einen im wesentlichen quadratischen Querschnitt, der insbesondere auch besonders gut zu einem äußeren Steherteil mit im wesentlichen quadratischem Querschnitt und vier hinterschnittenen Längsvertiefungen paßt.The inner upright part preferably has one square cross section, which is particularly good too an outer upright part with a substantially square cross section and four undercut longitudinal recesses.

    Vorzugsweise weist die betreffende Traverse an jedem Traversenende einen Traversenkopf auf, der ein gegossenes oder ein geschmiedetes Werkstück ist und der die der Festlegung der betreffenden Traverse an dem betreffenden Steher dienenden Mittel enthält. Infolgedessen kann man die Traverse als sehr einfaches Profil ausbilden; die der Festlegung dienenden Mittel sind ausschließlich an dem betreffenden Traversenkopf gehaltert, der die hierfür erforderliche, kompliziertere Formgebung ohne Schwierigkeiten haben kann. The crossmember in question preferably has at each end of the crossbar a truss head that is cast or forged Workpiece is and that of the definition of the relevant traverse contains the agent in question. As a result, can to design the crossbeam as a very simple profile; that of fixing serving means are only on the relevant truss head supported, the required, more complicated shape without May have difficulty.

    Weiter vom ist bei der Wiedergabe der erfindungsgemäßen Lösung die Ausdrucksweise gewählt worden, daß "mindestens bei einem erheblichen Teil der Steher/Traversenende-Verbindungsstellen" eine bestimmte Festlegung vorgesehen sei. Hiermit soll zum Ausdruck gebracht werden, daß es für die Verwirklichung der Erfindung nicht unerläßlich ist, daß alle Steher/Traversenende-Verbindungsstellen in der beschriebenen Weise ausgebildet sind. So wäre es z.B. möglich, nur bei jeden zweiten Traverse die spezielle formschlüssige Festlegung vorzusehen. Insgesamt ist aber bevorzugt, bei dem öffnungsgemäßen Gerüst durchgängig die erfindungsgemäße Maßnahme vorzusehen. Analoges gilt für viele der beschriebenen Vorzugsmerkmale. Sie können an einzelnen Stellen des betrachteten Gesamtgerüsts verwirklicht sein, vorzugsweise jedoch durchgängig an den in Frage kommenden Stellen.Farther from is the reproduction of the solution according to the invention Expressively chosen that "at least with a substantial Part of the uprights / truss end connection points "a certain Determination was provided. This is to express that it is not essential for the implementation of the invention that all upright / truss end connection points in the described Are trained. So it would be e.g. possible, only every second Traverse to provide the special positive locking. All in all is preferred, however, in the scaffold according to the opening provide measure according to the invention. The same applies to many of the described preferred features. You can at individual points in the considered overall framework, but preferably consistently at the points in question.

    Das erfindungsgemäße Gerüst kommt für zahlreiche technische Gebiete in Betracht. Zuerst sei der Baubereich genannt, wo man insbesondere Deckenschalungen, ganz besonders solche in beträchtlicher Höhe, errichten kann (was häufig Schalungstisch genannt wird). Ein weiteres Feld sind die Arbeitplattformen, insbesondere in erheblicher Höhe (die häufig Lasttürme genannt werden). Dort kann man z.B. große und schwere Bauteile zusammenbauen und anschließend an einem daneben stehenden Gebäude befestigen. Oder man denke an die Durchführung von Arbeiten von unten her an einem Brückbogen. Ein weiteres Gebiet sind Arbeitsbühnen, aber auch Bühnen für Vorführungen, Ansprachen oder dergleichen. Auch Gerüste für Zuschauertribünen, die Begehflächen auf mehreren Höhen aufweisen, gehören ausdrücklich zum Bereich der Erfindung. Schließlich seien Fassadengerüste genannt, bei denen normalerweise die Traversen, mindestens zum Teil, aufgelagerte Arbeitsplattformen tragen.The scaffold according to the invention comes in numerous technical fields into consideration. First is the construction area, where one in particular Slab formwork, especially those at considerable heights, can erect (which is often called formwork table). Another one Fields are the work platforms, especially in considerable amounts (the often called load towers). There you can e.g. large and Assemble heavy components and then on one next to it fasten standing buildings. Or think of the implementation from work on a bridge arch from below. Another area are working platforms, but also stages for demonstrations and speeches or similar. Also scaffolding for bleachers, the walk-in areas have at different heights are explicitly part of the range Invention. Finally, facade scaffolding should be mentioned in which usually the trusses, at least in part, supported Wear work platforms.

    Die Erfindung und Weiterbildungen der Erfindung werden nachfolgend anhand eines zeichnerisch dargestellten Ausführungsbeispiels noch näher erläutert. Es zeigt:

    a view of a truss end piece according to arrow IV in Fig. 1, on an enlarged scale.

    Die dargestellte Deckenschalung ist zugleich die Veranschaulichung eines Gerüsts, wenn man sich vorstellt, daß die später zu beschreibenden Platten nicht eine Schalung für das Betonieren sind.The slab formwork shown is also an illustration of a scaffold, if you imagine that those to be described later Slabs are not formwork for concreting.

    Der in Fig. 1 gezeichnete Ausschnitt einer Deckenschalung besteht aus folgenden Kernbestandteilen: vertikale Steher 2, horizontale Hauptträger 4, die sich jeweils mit ihren beiden Endbereichen an zwei Stehern 2 abstützen, horizontalen Nebenträgern 6, die sich normalerweise jeweils auf zwei Hauptträgern 4 abstützen, Schalplatten 8, die jeweils auf Nebenträgem 6 aufgelagert sind, und Traversen 10, die - wenn und wo für die Stabilität der Deckenschalung erforderlich - als versteifende Querverbindungen von Stehern 2 vorgesehen sind. Der gezeichnete Steher 2 ist nur mit einem oberen Teil seiner Länge gezeichnet; ein unterer Bereich seiner Länge ist in Fig. 3 gezeichnet.The section of a slab formwork drawn in Fig. 1 consists of following core components: vertical uprights 2, horizontal main beams 4, each with its two end regions on two uprights 2 support, horizontal secondary beams 6, which are normally each supported on two main beams 4, formwork panels 8, each on Supports 6 are supported, and trusses 10, which - if and where required for the stability of the slab formwork - as stiffening Cross connections of uprights 2 are provided. The drawn one Post 2 is only drawn with an upper part of its length; on lower region of its length is drawn in Fig. 3.

    Der gezeichnete Ausschnitt der Deckenschalung zeigt nur einen Steher 2. Für die Deckenschalung in ihrer Gesamtheit ist eine Vielzahl von Stehern 2 in einem Gitterpunktmuster vorgesehen, z. B. mit einem Abstand in Hauptträger-Längsrichtung von 1,5 m und einem Abstand in Nebenträger-Längsrichtung von 3 m. The drawn section of the ceiling formwork shows only one post 2. For the slab formwork in its entirety is a variety of Stand 2 provided in a grid point pattern, for. B. with a Distance in the main beam longitudinal direction of 1.5 m and a distance in Longitudinal beam of 3 m.

    Der Steher 2 hat in seinem in Fig. 1 unteren Teil 11 einen im wesentlichen quadratischen Querschnitt mit vier schwalbenschwanzförmigen Längsvertiefungen 14, jeweils mittig in einer Quadratseite. In seinem in Fig. 1 oberen Teil 12 hat der Steher 2 einen quadratischen Querschnitt, der mit den zum Inneren des Stehers 2 weisenden Oberflächen der Längsvertiefungen 14 zusammenpaßt. Der obere Teil 12 ist teleskopisch in den unteren Teil 11 des Stehers 2 eingeschoben. Der obere Teil 12 weist in jeder seiner Quadratseiten eine vertikale Reihe von Öffnungen 16 auf, der untere Teil 11 weist im Grund jeder Längsvertiefung 14 ebenfalls eine in Längsrichtung verteilte Reihe von Öffnungen 18 auf, wobei das Abstands-Rastermaß bei beiden Öffnungsreihen gleich ist. Man kann den oberen Teil 12 weiter in den unteren Teil 11 hineinschieben oder weiter herausziehen. Mittels eines durch zwei Öffnungspaare 16, 18 hindurchgeschobenen Stifts 20 kann man den Steher in der gewünschten Länge fixieren.The upright 2 has in its lower part 11 in FIG essential square cross section with four dovetail-shaped longitudinal recesses 14, each centered in one Square side. In its upper part 12 in FIG. 1, the upright 2 has one square cross-section, with the inside of the post 2 facing surfaces of the longitudinal recesses 14 fits together. The upper part 12 is telescopic in the lower part 11 of the post 2 inserted. The upper part 12 has one in each of its square sides vertical row of openings 16, the lower part 11 has in Due to each longitudinal recess 14 also a distributed in the longitudinal direction Row of openings 18, the spacing of both Rows of openings is the same. You can continue the upper part 12 in the Push lower part 11 in or pull out further. By means of a can be pushed through two pairs of openings 16, 18 pin 20 to fix the post in the desired length.

    Als oberen Abschluß weist der Steher 2 ein Kopfstück 22 mit einem plattenartigen, etwas vergrößerten, oberen Ende auf.As an upper end, the upright 2 has a head piece 22 with a plate-like, somewhat enlarged, upper end.

    Ein Stück unterhalb des Kopfstücks 22 ist an dem Steher 2 ein Fallkopf 24 befestigt, der an zwei Seiten des Stehers 2 eine auskragende Abstützfläche 26, jeweils für einen Endbereich eines Hauptträgers 4 auf. Von jeder Abstützfläche 26 ragen zwei Kurzbolzen 42 als Vorstehelemente nach oben.A piece below the head piece 22 is a drop head on the upright 2 24 attached, the cantilever on two sides of the post 2 Support surface 26, each for an end region of a main support 4. Two short bolts 42 protrude from each support surface 26 Protruding elements upwards.

    Es wird darauf hingewiesen, daß das Kopfstück 22 gewünschtenfalls gegen ein leich abgewandeltes Kopfstück mit verkleinertem, plattenartigen, oberen Ende ausgetauscht werden kann. Dann läßt sich bei ganz nach oben verschobenem Fallkopf 24 eine durchgehende Abstützfläche 26 schaffen, sodaß ein darüber hinwegführender Hauptträger in seinem mittleren Bereich abgestützt werden kann.It is noted that the head 22 if desired against a slightly modified headpiece with a reduced, plate-like, upper end can be replaced. Then you can with the drop head 24 shifted all the way to the top Create support surface 26 so that a leading over it Main beam can be supported in its central area.

    Bis auf weiter unten noch zu beschreibende Unterschiede sind die Hauptträger 4 (von denen in Fig. 1 einer gezeichnet ist) und die Nebenträger 6 (von denen in Fig. 1 zwei gezeichnet sind) gleich ausgebildet. Sie bestehen jeweils aus zwei Halbträgern mit im wesentlichen U-förmigem, zur Seite offenen Profil. Die beiden Halbträger 4a, 4b bzw. 6a, 6b sind mit den Rücken einander zugewandt und mit Abstand miteinander verbunden. Die Verbindung der Halbträger ist durch Schrauben oder Bolzen 30 vorgenommen, wobei Abstandshalter 32 aus Kunststoff zwischen die beiden Halbträger zwischengesetzt sind (Fig. 2). Über die Länge der Träger 4, 6 verteilt sind Verbindungsbolzen 30 und Abstandshalter 32 an mehreren Stellen vorgesehen.Except for the differences to be described below, these are Main beam 4 (one of which is drawn in Fig. 1) and the Subcarrier 6 (two of which are drawn in Fig. 1) are the same educated. They each consist of two half beams with in essential U-shaped profile open to the side. The two Half beams 4a, 4b and 6a, 6b face one another with their backs and connected with each other at a distance. The connection of the half beams is made by screws or bolts 30, wherein Spacers 32 made of plastic between the two half beams are interposed (Fig. 2). Distributed over the length of the carrier 4, 6 are connecting bolts 30 and spacers 32 in several places intended.

    Durch die waagerechten, oberen Schenkel der beiden Halbträger 4a, 4b wird bei dem Hauptträger 4 eine obere Lagerfläche 34 gebildet. Analog wird durch die unteren, waagerechten Schenkel der Halbträger 6a, 6b bei dem Nebenträger 6 eine untere Lagerfläche 36 gebildet. Auch der Nebenträger 6 hat eine obere Lagerfläche 38, analog dem Hauptträger 4.Through the horizontal, upper legs of the two half beams 4a, 4b an upper bearing surface 34 is formed in the main carrier 4. Analogous is through the lower, horizontal legs of the half-beam 6a, 6b a lower bearing surface 36 is formed in the secondary carrier 6. Also the Secondary support 6 has an upper bearing surface 38, analogous to main support 4.

    Alle vier waagerechten Schenkel des Hauptträgers 4 und alle vier waagerechten Schenkel des Nebenträgers 6 sind jeweils mit einer Reihe von in einem Rastermaß beabstandeten, kreisrunden Öffnungen 40 versehen, das Rastermaß a ist überall gleich. Jeweils mittig zwischen benachbarten Öffnungen 40 sind in allen waagerechten Schenkeln kreisrunde, weitere Öffnungen 41 kleineren Durchmessers vorhanden. In den in den zwei oberen waagerechten Schenkeln des Hauptträgers 4 vorgesehenen, weiteren Öffnungen 41 sind Kurzbolzen 42 vorzugsweise aus Kunststoff befestigt (z. B. durch Schulteranlage oben und Heißumdrücken unten hinter der weiteren Öffnung 41), die in ihren nach oben fortragenden Bereich einen kreisrunden Querschnitt hineinpassend jeweils in eine Öffnung 40 des Partnerträgers haben, aber sich leicht konisch verjüngend nach oben. Dies war der erste Unterschied zwischen dem Hauptträger 4 und dem Nebenträger 6 (der keine Kurzbolzen 42 aufweist); ein zweiter Unterschied liegt in der etwa doppelt so großen Länge des Nebenträgers 6, wie bereits weiter vom angedeutet. All four horizontal legs of the main beam 4 and all four horizontal legs of the secondary beam 6 are each with a row of circular openings 40 spaced apart in a grid dimension provided, the grid dimension a is the same everywhere. Each in the middle between adjacent openings 40 are in all horizontal legs circular, further openings 41 of smaller diameter available. In in the two upper horizontal legs of the main beam 4 provided further openings 41, short bolts 42 are preferred made of plastic (e.g. by shoulder system on top and Hot stamping below behind the further opening 41), which in its after a circular cross section fitting into the area above have each in an opening 40 of the partner carrier, but easy tapering upwards. That was the first difference between the main beam 4 and the secondary beam 6 (which are not short bolts 42 having); a second difference is that it is about twice as large Length of the secondary beam 6, as already indicated by the.

    Man erkennt, daß jeder der gezeichneten Nebenträger 6 mit zwei Öffnungen 40 in seiner unteren Lagerfläche 36 zwei Kurzbolzen 42 aufgenommen hat, die aus der oberen Lagerfläche 34 des Hauptträgers 4 nach oben vorstehen. Hierdurch ist eine formschlüssige Festlegung des betreffenden Nebenträgers 6 auf dem betreffenden Hauptträger 4 gegenüber Kräften beliebiger Richtung in der Lagerflächenebene (d. h. die durch die Lagerflächen 34, 36 gebildete Ebene) gebildet.It can be seen that each of the subcarriers 6 shown with two Openings 40 in its lower bearing surface 36 two short bolts 42 has taken up from the upper bearing surface 34 of the main carrier 4th protrude upwards. This is a positive definition of relevant secondary beam 6 on the relevant main beam 4 against forces of any direction in the bearing surface plane (i.e. the plane formed by the bearing surfaces 34, 36).

    Ferner erkennt man in Fig. 1 zwei Schalplatten 8, die mit einem Stoß 50 aneinander anschließen. Die Schalplatten 8 sind auf Nebenträger 6 aufgelagert. Gezeichnet ist, daß eine Schalplatte 8 mit einem Rand auf dem Halbträger 6a des Nebenträgers 6 aufliegt, während die andere Schalplatte 8 mit einem Rand auf dem anderen Halbträger 6b des Nebenträgers 6 aufliegt derart, daß der Stoß 50 über den Abstandsraum zwischen den Halbträgern 6a, 6b zu liegen kommt. Man erkennt ferner, daß die Schalplatten 8 in ihren Auflagerungsrändern mit nach unten vorstehenden Kurzbolzen 52 versehen sind, die in Öffnungen 40 in der oberen Lagerfläche 38 des Nebenträgers 6 eingeführt sind, so daß die Schalplatten 8 formschlüssig festgelegt sind.Furthermore, two formwork panels 8 can be seen in FIG connect to each other. The formwork panels 8 are on secondary beams 6 superimposed. It is shown that a formwork panel 8 with an edge the half beam 6a of the secondary beam 6 rests while the other Formwork sheet 8 with an edge on the other half beam 6b of the Subcarrier 6 rests in such a way that the joint 50 over the space comes to lie between the half beams 6a, 6b. You can also see that the formwork panels 8 in their support edges with down projecting short bolts 52 are provided, which in openings 40 in the upper bearing surface 38 of the secondary beam 6 are inserted so that the Formwork panels 8 are positively fixed.

    Hauptträger 4 und Nebenträger 6 sind, mit Ausnahme der geschilderten zwei Unterschiede, identisch aufgebaut infolgedessen können sie auf der gleichen Fabrikationsstraße gefertigt werden, wobei die beschriebenen Öffnungen 40 und 41 und die weiter unten noch zu beschreibenden Öffnungen gestanzt werden, ehe die Halbträger in die Form des U-förmigen Profils gebogen werden. In der oberen Lagerfläche 34 nur des Hauptträgers 4 werden dann die Kurzbolzen 42 angebracht. Wenn man es aus Gründen gesteigerter Tragfähigkeit für günstiger hält, könnten die Öffnungen 40 in der oberen Lagerfläche 34 und/oder die Öffnungen 40 und 41 in der unteren Lagerfläche des Hauptträgers 4 gänzlich weggelassen werden, weil sie beim gezeichneten Ausführungsbeispiel funktionslos sind. Es wird ausdrücklich darauf hingewiesen, daß bei der Festlegung Steher 2/Hauptträger 4, Hauptträger 4/Nebenträger 6, Nebenträger 6/Schalplatte 8 die Rolle von Vorstehelement 42 bzw. 52 und Öffnung 40 jeweils umgekehrt sein kann als weiter vom beschrieben. An der Funktion ändert sich hierdurch nichts. Es wird ferner ausdrücklich darauf hingewiesen, daß man alternativ auch so vorgehen kann, daß die Kurzbolzen in dem Hauptträger 4 einen derartigen Abstand voneinander haben, daß ein Kurzbolzenpaar die zwei Außenränder 54 der unteren Lagerfläche 36 des aufgelagerten Nebenträgers 6 zwischen sich einschließt. Hierdurch wäre noch keine formschlüssige Festlegung in Längsrichtung des Nebenträgers 6 erreicht, aber man könnte z.B. Kurzbolzen in der unteren Lagerfläche 36 des Nebenträgers 6 anbringen, die mit Längsrändern 56 eines Halbträgers 4a des Hauptträgers zusammenwirken.Main beams 4 and 6 are secondary beams, with the exception of those described two differences, constructed identically as a result, you can on the same production line are manufactured, the described Openings 40 and 41 and those to be described below Openings are punched out before the semi-beams are shaped into the U-shape Profiles are bent. In the upper bearing surface 34 only the Main beam 4, the short bolts 42 are then attached. If considers it cheaper for reasons of increased load-bearing capacity Openings 40 in the upper bearing surface 34 and / or the openings 40 and 41 in the lower bearing surface of the main beam 4 entirely be omitted because they are in the drawn embodiment are inoperative. It is expressly pointed out that the Fixing uprights 2 / main beam 4, main beam 4 / secondary beam 6, Secondary support 6 / formwork sheet 8 the role of protruding element 42 or 52 and opening 40 can each be reversed as farther from described. This does not change the function. It will also expressly pointed out that one can alternatively also can proceed that the short bolts in the main carrier 4 a have such a distance from each other that a pair of short bolts the two Outer edges 54 of the lower bearing surface 36 of the superimposed Subcarrier 6 includes between them. This would not result in any positive locking in the longitudinal direction of the secondary beam 6 achieved, but you could e.g. Short bolt in the lower bearing surface 36 of the Attach secondary beam 6, which with longitudinal edges 56 of a half beam 4a of the main carrier cooperate.

    Bei dem beschriebenen Ausführungsbeispiel sind die Kurzbolzen 42 bzw. 52 in der Abstützfläche 26 des Stehers 2, in der oberen Lagerfläche 34 des Hauptträgers 4, und unten an den Platten 8 hinsichtlich ihres Durchmessers im vorragenden Bereich, hinsichtlich ihrer leichten Konizität und hinsichtlich ihres Materials (Kunststoff) gleich. Das ist kein zwingendes Erfordernis. Außerdem könnte man die Kurzbolzen z.B. auch aus Metall vorsehen.In the described embodiment, the short bolts 42 or 52 in the support surface 26 of the upright 2, in the upper bearing surface 34 of the main support 4, and below on the plates 8 with respect to their Diameter in the protruding area, in terms of their light weight Taper and the same in terms of their material (plastic). This is no imperative. You could also use the short bolts e.g. Provide also made of metal.

    Der gegenseitige, formschlüssige Eingriff zwischen dem Steher 2, einem Hauptträger 4, einem Nebenträger 6 und einer Platte 8 ist in Fig. 2 anschaulicher erkennbar. Nach oben abgebogene Laschen 27 an den Abstützflächen 26 des Stehers 2 greifen hinter Abstandshalter 32 der Hauptträger 4 und ergeben so ein besseres Hinführen zum Festlegen mittels der Kurzbolzen 42.The mutual, positive engagement between the upright 2, one The main carrier 4, a secondary carrier 6 and a plate 8 are shown in FIG. 2 recognizable more clearly. Tabs 27 bent upwards on the Support surfaces 26 of the post 2 engage behind the spacer 32 Main beam 4 and thus result in a better direction for fixing by means of the short bolts 42.

    In den Fig. 1 und 2 sieht man ferner Öffnungen 44 größeren Durchmessers und weitere Öffnungen 45 kleineren Durchmessers, angeordnet in insgesamt drei Reihen, in den vertikalen Stegen der Träger 4 und 6. Hier können Anschlußbefestigungen vorgenommen werden, wie weiter vom geschildert. 1 and 2 you can also see openings 44 larger Diameter and further openings 45 of smaller diameter, arranged in a total of three rows, in the vertical webs of the Beams 4 and 6. Here you can make connections as described further on.

    In Fig. 3 ist ein unterer Bereich des Stehers 2 von Fig. 1 und 2 dargestellt. In den Steherteil 11 ist von unten ein Fußteil 94 eingeschoben, das einen quadratischen Querschnitt wie der obere Teil 12 besitzt, und mittels eines durch Öffnungen 16, 18 hindurchgesteckten Zapfens 20 gesichert. Am unteren Ende weist das Fußteil 94 einen Spindelbereich 96 zum genauen Einstellen der Länge des Stehers 2 auf.3 is a lower region of the upright 2 from FIGS. 1 and 2 shown. A foot part 94 is in the upright part 11 from below inserted, which has a square cross section like the upper part 12 has, and by means of a through openings 16, 18 inserted Pin 20 secured. At the lower end, the foot part 94 has one Spindle area 96 for precise adjustment of the length of the post 2.

    Die in Fig. 1 gezeichneten Traversen 10 haben jeweils einen U-förmigen, zur Seite hin offenen Querschnitt. An jedem Traversenende ist ein Traversenkopf 60 befestigt, z. B. festgeschweißt. Die Traversenköpfe 60 sind jeweils zu der eingezeichneten Vertikalebene 62-62 symmetrisch und können ohne Umorientierung für beide Traversenenden eingesetzt werden. Bei dem gezeichneten Ausführungsbeispiel sind die Traversenköpfe 60 als gegossene oder geschmiedete Teile ausgeführt. An dem von der Traverse 10 abgewandten Ende hat jeder Traversenkopf 60 zwei waagrechte, vorstehende Rippen 74.The cross members 10 shown in FIG. 1 each have a U-shaped, cross section open to the side. At each end of the truss a truss head 60 attached, e.g. B. welded. The Traverse heads 60 are each to the vertical plane 62-62 symmetrical and can be reoriented for both Truss ends are used. With the drawn The crosshead heads 60 are cast or cast forged parts. At that of the traverse 10 opposite end, each truss head 60 has two horizontal, protruding ribs 74.

    Einige Einzelheiten des Traversenkopfs 60 kann man in Fig. 4 besser sehen.Some details of the truss head 60 can be seen better in FIG. 4 see.

    Etwa in seiner Mitte weist der Traversenkop 60 eine durchgehende Bohrung auf, in die längsverschiebbar ein Bolzen 64 eingesetzt ist. Die Längsrichtung des Bolzens 64 fällt mit der Längsrichtung der Traverse 10 zusammen. Der Bolzen 64 weist einen Bolzenkopf 66 auf, der bei der ganz rechts in Fig. 1 gezeichneten Traverse 10 in der gezeichneten Drehposition des Bolzens 64 gemessen in waagerechter Richtung schmaler ist als gemessen in senkrechter Richtung. In dieser gezeichneten Drehposition läßt sich der Bolzenkopf 66, wie weiter unten noch genauer beschrieben werden wird, von vorn her in eine der Längsvertiefungen 14 des Stehers 2 einführen. Wenn man dann den Bolzen 64 um etwa 90° um seine Längsachse dreht, verriegelt sich der Bolzenkopf 66 in der schwalbenschwanzförmig hinterschnittenen Längsvertiefung 14, ohne jedoch schon darin festgeklemmt zu sein. The traverse head 60 has a continuous one approximately in its center Bore in which a bolt 64 is longitudinally displaceable. The The longitudinal direction of the bolt 64 coincides with the longitudinal direction of the cross member 10 together. The bolt 64 has a bolt head 66, which at the traverse 10 shown on the far right in FIG Rotational position of the bolt 64 measured in the horizontal direction is narrower than measured in the vertical direction. In this drawn rotational position, the bolt head 66, as below will be described in more detail from the beginning in one of the Introduce longitudinal recesses 14 in the upright 2. If you do that Bolt 64 rotates about 90 ° about its longitudinal axis, the locks Bolt head 66 in the dovetail undercut Longitudinal recess 14, but without already being clamped in it.

    Am von der Traverse 10 abgewandten Endbereich des Bolzens 64 ist integral ein Vorstehelement 68 mit kreisrundem Querschnitt vorgesehen, vorstehend in Längsrichtung des Bolzens 64 über den bisher beschriebenen Bolzenkopf 66 hinaus. Das Vorstehelement 68 ist von seinem Durchmesser her auf die Öffnungen 18 bzw. 16 im Steher 2 abgestimmt. Ferner sind die Abmessungen so gewählt, daß man die beschriebene Drehung des Bolzens 64 um seine Längsachse nur vollziehen kann, wenn der Bolzen 64 so weit nach rechts in Fig. 2 (nach links in Fig. 1 bei der dortigen, ganz rechten Traverse 10) verlagert worden ist, daß das Vorstehelement 68 sich in einer Öffnung 18 des Stehers 2 befindet.At the end region of the bolt 64 facing away from the crossmember 10 integrally provided a projecting element 68 with a circular cross section, protruding in the longitudinal direction of the bolt 64 over the previously described bolt head 66 also. The protruding element 68 is from its diameter on the openings 18 and 16 in the upright 2 Voted. Furthermore, the dimensions are chosen so that the described rotation of the bolt 64 only about its longitudinal axis can complete if the bolt 64 so far to the right in Fig. 2 (after 1 in the right-hand traverse 10) there has been that the protruding element 68 in an opening 18 of the Stayer 2 is located.

    Der Bolzen 64 besitzt eine längliche Durchgangsöffnung 70, die in Fig. 4 mit unterbrochenen Linien eingezeichnet ist und die Gestalt eines flachen Quaders hat. Es ist ein Keilelement 72 vorgesehen, das diese Durchgangsöffnung 70 durchsetzt.The bolt 64 has an elongated through opening 70 which is shown in FIG. 4 is drawn with broken lines and the shape of a flat cuboids. A wedge element 72 is provided that this Through opening 70 passes through.

    Wenn man den Traversenkopf 60 in einem Schnitt 76-76 betrachtet (siehe Fig. 4), dann hat der Traversenkopf 60 an der linken Seite eine obere Aussparung 78 und an der rechten Seite eine untere Aussparung 80. Infolgedessen kann man das Keilelement 72 aus der rechts in Fig. 1 gezeichneten, waagerechten Position in die in Fig. 2 gezeichnete, senkrechte Position drehen. In der senkrechten Position wirkt die Vorderfläche 82 des Keilelements 72 mit einer Widerlagerfläche 84 des Traversenkopfs 60 zusammen. Deshalb kann die gegenüber der Vorderfläche 82 schräg verlaufende Rückfläche 86 des Keilelements 72 im Zusammenwirken mit einem Ende 88 der Durchgangsöffnung 70 eine Längsverlagerung des Bolzens 64 nach links in Fig. 4 mit Keilkraft bewirken. Das Keilelement 72 ist durch einen Querstift 90 an einem seiner Enden unverlierbar, wodurch auch der Bolzen 64 unverlierbar ist.If you look at the crosshead 60 in a section 76-76 (see Fig. 4), then the truss head 60 has one on the left side upper recess 78 and on the right side a lower recess 80. As a result, the wedge element 72 can be seen from the right in FIG. 1 drawn, horizontal position in the drawn in Fig. 2, Turn the vertical position. It works in the vertical position Front surface 82 of the wedge element 72 with an abutment surface 84 of the Truss head 60 together. Therefore, the opposite of the Front surface 82 of oblique rear surface 86 of wedge element 72 in cooperation with one end 88 of the through opening 70 Longitudinal displacement of the bolt 64 to the left in Fig. 4 with wedge force cause. The wedge element 72 is by a cross pin 90 on one its ends captive, whereby the bolt 64 is captive.

    Bei der Anbringung einer Traverse 10 zwischen zwei Steher 2 geht man folgendermaßen vor (wobei nur die Vorgänge an einem Traversenende beschrieben werden, es sich aber versteht, daß die beschriebenen Vorgänge an beiden Traversenenden durchgeführt werden):When attaching a traverse 10 between two uprights 2 you go as follows (only the processes at one end of the truss be described, but it is understood that the described Operations are carried out at both ends of the truss):

    Zunächst wird durch Angreifen an dem Keilelement 72 der Bolzen 64 - selbstverständlich mitsamt seinem Bolzenkopf 66 und dem daran integrierten Vorstehelement 68 - so weit nach links in Fig. 4 verlagert, daß sich der gesamte Bolzenkopf 66 in dem Raum zwischen den beiden Rippen 74 befindet, und wird das Keilelement 72 waagerecht gestellt. In diesem Zustand ragt weder der Bolzenkopf 66 noch das Vorstehelement 68 über die Rippen 74 hinaus, die Traverse 10 kann von der Seite her zwischen die zwei Steher 2 eingeschoben werden. Als nächstes wird durch Angreifen an dem Keilelement 72 der Bolzenkopf 66 aus dem Raum zwischen den Rippen 74 herausbewegt und in die Längsvertiefung 14 des betreffenden Stehers 2 hineinbewegt, und zwar so weit, daß das Vorstehelement 68 in eine Öffnung 18 des Stehers 2 hineinkommt. Dann wird das Keilelement 72 um etwa 90 Grad gedreht, der Bolzenkopf 66 wird in waagerechter Richtung breiter und versperrt sich in der hinterschnittenen Längsvertiefung 14. Anschließend wird von oben in Fig. 4 mit einem Hammer auf das Keilelement 72 geschlagen, wodurch der Bolzen 64 nach links in Fig. 4 gezogen und der Bolzenkopf in der Längsvertiefung 14 festgeklemmt wird (weil die Rippen 74 an der Außenseite des Stehers 2 ein Widerlager bilden); das Vorstehelement 68 ist lang genug, damit es durch diesen Klemmvorgang nicht aus der Öffnung 18 herauskommt. Das Lösen der Festlegung der Traverse 10 an dem betreffenden Steher 2 erfolgt in umgekehrter Abfolge.First, by engaging the wedge element 72, the bolt 64 - of course, together with his bolt head 66 and that integrated protruding element 68 - shifted as far to the left in FIG. 4, that the entire bolt head 66 in the space between the two Ribs 74 is located, and the wedge element 72 is placed horizontally. In In this state, neither the bolt head 66 nor the protruding element protrudes 68 beyond the ribs 74, the cross member 10 can from the side be inserted between the two uprights 2. Next up by engaging the wedge element 72, the bolt head 66 from the Space moved out between the ribs 74 and into the longitudinal recess 14 of the post 2 in question, so far that the Projecting element 68 comes into an opening 18 of the post 2. Then the wedge element 72 is rotated by approximately 90 degrees, the bolt head 66 becomes wider in the horizontal direction and blocks itself in the undercut longitudinal recess 14. Then from above in Fig. 4 struck with a hammer on the wedge element 72, whereby the bolt 64 is pulled to the left in Fig. 4 and the bolt head in the Longitudinal recess 14 is clamped (because the ribs 74 on the Form an abutment on the outside of the upright 2); the protruding element 68 is long enough so that it does not come out of the Opening 18 comes out. The loosening of the fixing of the traverse 10 the relevant post 2 takes place in reverse order.

    Wenn auf die beschriebenen Schalungsplatten 8 Beton gegossen werden soll, hat man, wie beschrieben, eine Deckenschalung vor sich. Wenn hingegen die durch die Platten 8 gebildete Fläche z. B. zum Begehen durch Arbeitspersonen oder zum Auflagern eines Anlagenteils, das hernach an einem anderen Bauwerksteil befestigt werden soll, genutzt wird, kann man nicht mehr von einer Deckenschalung sprechen, sondern spricht besser von einer Plattform oder einer (Arbeits-) Bühne. An dem beschriebenen, erfindungsgemäßen Aufbau ändert sich hierdurch naturgemäß nichts.If 8 concrete is poured onto the formwork panels described , as described, you have a slab formwork in front of you. If however, the area formed by the plates 8 z. B. to walk on by workers or to support a part of the system that subsequently to be attached to another part of the building one can no longer speak of slab formwork, but speaks better of a platform or a (work) stage. To the described construction according to the invention changes as a result naturally nothing.

    Alternativ kann man das in Fig. 1 Gezeichnete auch ein Gerüst nennen, und zwar spricht man von einem Lehrgerüst, wenn das Einleiten von Lasten von den Köpfen der Steher 2 her im Vordergrund steht, und von einem Arbeitsgerüst, wenn das Einleiten von Lasten von den Traversen 10 her im Vordergrund steht. Im Fall eines Gerüsts müssen die Platten 8 nicht zwangsläufig vorhanden sein. Bei Ausbildung als Arbeitsgerüst sind vorzugsweise mindestens bei einem Teil der Traversen dort Arbeitsplattformen aufgelagert.Alternatively, what is drawn in Fig. 1 can also be called a framework, and one speaks of a framework if the initiation of Loads from the heads of the uprights 2 are in the foreground, and from a scaffolding when introducing loads from the trusses 10 ago is in the foreground. In the case of a scaffold, the plates 8 not necessarily exist. When training as a scaffolding are preferably there at least in part of the trusses Working platforms stored.
