    • Das Gerüst weist einen ersten horizontalen Träger 1 auf, der als Kastenträger mit rechteckigem Querschnitt ausgebildet ist. An der Unterseite dieses Trägers 1 sind in gleichmäßigem Abstand über dessen Länge L jeweils paarweise L-förmige Leisten 3 angeschweißt, und zwar in der Weise, daß ihre frei auskragenden Schenkel gegeneinander gerichtet sind, wodurch ein nach unten offenes, hinterschnittenes U-Profil gebildet wird. An den Enden dieses Trägers 1 sind horizontal liegende Rohrhülsen 4 an den Seitenwangen angeschweißt, die zur Verbindung von in horizontaler Richtung aufeinanderfolgenden Trägern dienen. An der Oberseite 5 dieses ersten kastenartigen Trägers 1 sind kegelförmige Positionierungselemente 6 festgelegt, die mit hier nicht dargestellten Schalungsrahmen für Schalungstafeln zusammenwirken und diese positionieren, wenn eine Schalung mit diesem Gerüst aufgebaut wird. In horizontalen Abständen, die den Abständen der die U-Profile bildenden Leisten 3 entsprechen, sind von der Seitenwange des Trägers 1 ausgehende, keilförmige Einschnitte 7 vorgesehen, die stirnseitig an ihrer offenen Seite von Laschen 8 überbrückt sind, die mit der Seitenwange des Trägers 1 verschraubt sind, wobei zumindest eine Bohrung einer solchen Lasche 8, die der Aufnahme einer Befestigungsschraube dient, als Langloch ausgebildet ist.The scaffold has a first horizontal support 1, which is used as a box support rectangular cross section. At the bottom of this carrier 1 are at regular intervals along its length L in pairs L-shaped strips 3 welded, in such a way that their cantilevered legs are directed towards each other, creating an undercut that is open at the bottom U-profile is formed. At the ends of this support 1 are horizontal Pipe sleeves 4 welded to the side cheeks, which are used to connect in serve horizontal direction successive beams. At the top 5 of this first box-like carrier 1 are conical positioning elements 6 set, the formwork frame for formwork panels, not shown here interact and position them when formwork with this scaffold is built up. At horizontal intervals that correspond to the intervals of the U-profiles corresponding strips 3 are from the side cheek of the carrier 1st outgoing, wedge-shaped incisions 7 are provided, the front of their open Are bridged by tabs 8, which are screwed to the side cheek of the carrier 1 are, wherein at least one bore of such a tab 8, the Receiving a fastening screw is used as an elongated hole.

    An der Unterseite 2 dieses horizontalen Trägers 1 sind nun schräg stehende Hohlprofile 9 vorgesehen, die hier nach unten gerichtet sind. Diese einen rechteckigen Querschnitt aufweisenden Hohlprofile 9 tragen an ihrem oberen Ende eine Platte 10, wobei die Ebene dieser Platte 10 und die Längsachse des Hohlprofiles 9 einen spitzen Winkel miteinander einschließen. Unter Zwischenschaltung eines Stützsteges 11 sind diese beiden Teile miteinander verschweißt. An der einen Längsseite des Hohlprofiles 9 sind seitlich auskragende Laschen 12 vorgesehen, deren Unterseite mit der Unterseite des Hohlprofiles 9 bündig liegt und die je eine Bohrung zur Aufnahme einer Befestigungsschraube besitzen, mit welcher eine hier nicht dargestellte Schaltafel befestigt werden kann. Im unteren Bereich dieses Hohlprofiles 9 sind Bohrungen 18 in einer Reihe mit einer Teilung t vorgesehen, wobei diese Teilung beispielsweise 40 mm betragen kann. An der Außenseite, ebenfalls im unteren Bereich des Hohlprofiles 9, ist ein Widerlager 13 aus einem Winkelprofil angeschweißt, dessen vertikaler Schenkel 14 eine Gewindebohrung, hier in Form einer angeschweißten Mutter 15 aufweist. In dieses Hohlprofil 9 ist ein Stützprofil 16 teleskopartig einsetzbar, das ebenfalls einen rechteckigen Querschnitt besitzt und das an seinem unteren Ende eine Fußplatte 17 mit Bohrungen trägt. Dieses Stützprofil 16 besitzt ebenfalls eine Reihe von Bohrungen 19, wobei jedoch die Teilung T dieser Lochreihen etwas größer gewählt ist als die Teilung t des Hohlprofiles 9. Beträgt beispielsweise die Teilung t 40 mm, so werden für die Teilung T 50 mm vorgesehen. Dank dieser Teilungswahl ist eine kleinstufige Längenveränderung dieses Stützprofiles möglich. Die teleskopartig ineinander steckbaren und gegeneinander verschiebbaren Hohlprofile werden bei deckungsgleicher Lage von Bohrungen 18 und 19 durch einen hier nicht dargestellten und gezeigten Arretierungsbolzen miteinander verbunden.On the underside 2 of this horizontal support 1 there are now slanted ones Hollow profiles 9 are provided, which are directed downwards here. This one rectangular Cross-section hollow profiles 9 carry at their upper end a plate 10, the plane of this plate 10 and the longitudinal axis of the hollow profile 9 form an acute angle with each other. Intermediate a support web 11, these two parts are welded together. On one longitudinal side of the hollow profile 9 are laterally projecting tabs 12 provided, the underside of which is flush with the underside of the hollow profile 9 and each have a hole for receiving a fastening screw with which a panel not shown here can be attached. At the bottom Area of this hollow profile 9 are holes 18 in a row with a division t is provided, this division being 40 mm, for example. At the Outside, also in the lower region of the hollow profile 9, is an abutment 13 welded from an angle profile, the vertical leg 14 of which is a threaded hole, here in the form of a welded nut 15. In this Hollow profile 9, a support profile 16 can be used telescopically, which also has a has a rectangular cross section and a footplate at its lower end 17 carries with holes. This support profile 16 also has a number of Bores 19, but the pitch T of these rows of holes is chosen somewhat larger is the pitch t of the hollow profile 9. For example, the pitch t 40 mm, T 50 mm are provided for the pitch. Thanks to this choice of division it is possible to change the length of this support profile in small steps. The telescopically insertable and mutually displaceable hollow profiles are in the congruent position of holes 18 and 19 by a here Not shown and shown locking bolt connected together.

    Diese Hohlprofile 9 mit den von ihnen aufgenommenen Stützprofilen 16 werden nun in der Weise mit dem horizontalen Träger 1 verbunden, daß die Platten 10 in die durch die Leisten 3 gebildeten U-Profile eingeschoben werden. In diesen Platten 10 sind Bohrungen vorgesehen, durch welche eine Befestigungsschraube einsteckbar und eindrehbar ist, um die Platte 10 bzw. das Hohlprofil 9 mit dem Träger 1 fest zu verbinden. Die Platte 10 kann abgeschrägte Seitenkanten haben, wodurch das Einschieben und Einfädeln dieser Platte in diese U-Profile erleichtert wird. Falls die zu fertigende Voute nicht gerade, sondern bogenförmig verläuft, so kann der horizontale erste Träger 1 gebogen werden: zu diesem Zweck werden die Schrauben 20 der Laschen 18 gelöst und jeweils die beiden, einen keilförmigen Einschnitt 7 begrenzenden Abschnitte des Trägers 1 gegeneinander gebogen und anschließend die Schrauben 20 wieder festgezogen. An der einen Seitenwange des Trägers 1 wird ein Streifen 22 einer Schaltafel festgeschraubt (Fig. 2). An der Unterseite der Hohlprofile 9 werden Schaltafeln 21 befestigt. Mit den Widerlagern 13 wird ein gerader oder gebogener zweiter Träger 23 verschraubt. Mehrere in der beschriebenen Weise vorbereitete Gerüste einschließlich Schaltafeln werden dann zu einer Schalung zusammengefügt. Der beschriebene Schalungsteil wird dann mittels Befestigungsschrauben, die durch die Bohrungen in den Fußplatten 17 gesteckt und mit einer Fundamentplatte verbunden werden, festgelegt.These hollow profiles 9 with the support profiles 16 they accommodate now connected to the horizontal support 1 in such a way that the plates 10 in the U-profiles formed by the strips 3 are inserted. In these Plates 10 are holes through which a fastening screw can be inserted and screwed in to the plate 10 or the hollow profile 9 with the To connect carrier 1 firmly. The plate 10 can have beveled side edges, which makes it easier to insert and thread this plate into these U-profiles becomes. If the haunch to be produced is not straight, but rather curved, then do so the horizontal first beam 1 can be bent: for this purpose the screws 20 of the tabs 18 are loosened and in each case the two, a wedge-shaped Incision 7 delimiting sections of the carrier 1 bent against each other and then tightened the screws 20 again. On one side cheek of the carrier 1, a strip 22 of a formwork panel is screwed tight (Fig. 2). Formwork panels 21 are attached to the underside of the hollow profiles 9. With the Abutments 13, a straight or curved second support 23 is screwed. Several scaffolds prepared in the manner described, including formwork panels are then put together to formwork. The one described Formwork part is then attached by means of fastening screws through the holes inserted in the base plates 17 and connected to a foundation plate, established.

    Beim gezeigten Ausführungsbeispiel sind die Platte 10 und das Hohlprofil 9 unter Zwischenschaltung eines Stützsteges 11 starr miteinander verbunden. Grundsätzlich ist es denkbar, zwischen diesen beiden Teilen eine scharnierartige Verbindung vorzusehen, so daß der Winkel zwischen diesen beiden Teilen verstellbar und einstellbar ist. Dies ist allerdings mit einem konstruktiven Mehraufwand verbunden. Zu diesem Zweck jedoch können hier vertikale Schraubspindeln eingesetzt werden. Sind beim gezeigten Ausführungsbeispiel die jeweils paargeordneten L-förmigen Leisten 3, die die U-Profile für die Aufnahme der Platten 10 bilden, an der Unterseite des Trägers 1 vorgesehen, so ist es denkbar, diese an einer Seitenwange des im Querschnitt rechteckigen Trägers anzuordnen. Der Winkel zwischen der Platte 10 und der Längsachse des Hohlprofiles 9 ist hier spitzwinkelig, da das beispielsweise beschriebene Gerüst für eine Innenschalung vorgesehen ist. Ist das Gerüst für eine Außenschalung vorgesehen, so wird der erwähnte Winkel stumpfwinkelig ausgebildet, dies unter Beibehaltung des prinzipiellen und vorstehend beschriebenen Aufbaues. Eine solche Anordnung zeigt Fig. 8, die einer Darstellung des Gerüstes nach Fig. 2 entspricht. Unter Berücksichtigung des vorstehend im einzelnen Dargelegten bedarf diese Fig. 8 keiner weiteren Erörterung.In the embodiment shown, the plate 10 and the hollow profile 9 are below Interposition of a support web 11 rigidly connected. in principle it is conceivable to have a hinge-like connection between these two parts provide so that the angle between these two parts is adjustable and is adjustable. However, this is with a constructive additional effort connected. However, vertical screw spindles can be used for this purpose become. Are the paired in the embodiment shown L-shaped strips 3, which form the U-profiles for receiving the plates 10, provided on the underside of the carrier 1, it is conceivable to this to arrange a side cheek of the cross-sectionally rectangular support. The Angle between the plate 10 and the longitudinal axis of the hollow profile 9 is here acute-angled, since the scaffold described for an internal formwork, for example is provided. If the scaffold is intended for external formwork, the mentioned angles obtuse, while maintaining the principle and structure described above. Such an arrangement shows Fig. 8, which corresponds to a representation of the scaffold of FIG. 2. Considering 8 does not require any of the details set out above further discussion.

    Dank des erfindungsgemäßen Gerüstes können sowohl gerade wie auch bogenförmig verlaufende Vouten mit relativ geringem Schalungsaufwand gefertigt werden. Die Höhe dieses Gerüstes ist dank der teleskopartigen Ausbildung der Hohlprofile 9 und 16 feinstufig einstellbar. Sollten die zu fertigenden Vouten gegenüber der Horizontale stark unterschiedliche Neigungen aufweisen, so ist es zweckmäßig, Hohlprofile 9 der beschriebenen Art in mehreren Ausführungen vorzusehen, wobei jeweils der Winkel zwischen der Platte 10 und der Längsachse des Hohlprofiles unterschiedlich gewählt ist, sofern nicht solche Hohlprofile eingesetzt werden, bei welchen dieser Winkel einstellbar ist. Thanks to the scaffold according to the invention can be both straight and arched running haunches can be manufactured with relatively little formwork. The height of this scaffold is thanks to the telescopic design of the hollow profiles 9 and 16 finely adjustable. Should face the haunches to be manufactured the horizontal has very different inclinations, so it is expedient to provide hollow profiles 9 of the type described in several versions, where the angle between the plate 10 and the longitudinal axis of the hollow profile is selected differently, unless such hollow profiles are used at which this angle is adjustable.
