Description

Schalungsträger zur Herstellung von Rundschalungen sind bekannt. In zusammengebautem Zustand sind die Schalungsträger polygon­ förmig und im Knickpunkt winkelverstellbar. Die Winkelverstellbar­ keit beruht dabei auf einem Gelenk, welches im gewünschten Winkel mittels Stellschraube festgehalten wird. Diese Schalungsträger werden darum auch Gelenkriegel genannt. Als Querschnitt der Ge­ lenkriegel werden in der Regel zwei mit Abstand voneinander ange­ ordnete U- Profile verwendet, zwischen denen die Durchankerung erfolgt.Formwork beams for the production of circular formwork are known. When assembled, the formwork beams are polygonal shaped and adjustable in angle at the break point. The angle adjustable speed is based on a joint that is at the desired angle is held by means of a set screw. These formwork beams are therefore also called lock bolts. As a cross section of Ge steering locks are usually placed at a distance from each other ordered U-profiles used, between which the anchorage he follows.

Eine Segmentschalung wird mittels Baukran zum nächsten Bauab­ schnitt versetzt. Ein Segment hat in der Regel ein Ausmaß von zehn bis zwölf Meter in Umfangrichtung und kann bis über sechs Meter hoch sein. Nun sollte die Außen- und die Innenschalung möglichst ohne Zerlegen mit dem Baukran versetzt werden können. Dazu ist es vorteilhaft, daß die Schalungsträger, von denen ja für Außenschalung und Innenschalung mindestens je zwei notwen­ dig sind, sehr stabil sind und möglichst wenig Gewicht aufweisen.A segment formwork becomes the next building using a construction crane cut offset. A segment usually has a size of ten to twelve meters in circumferential direction and can be up to six Be meters high. Now the outer and inner formwork should be can be moved with the construction crane if possible without disassembly. It is advantageous that the formwork beams, of which yes for external formwork and internal formwork at least two necessary dig, are very stable and have as little weight as possible.

Die Erfindung stellt sich nun die Aufgabe, einen Schalungsträger für eine Segmentschalung zu entwickeln, welcher bei geringem Gewicht eine hohe Stabilität aufweist.The invention now has the task of a formwork beam to develop for a segment formwork, which with low Weight has a high stability.

Dies wird mittels eines Schalungsträgers erreicht, welcher die Merkmale des Patentanspruches 1 aufweist.This is achieved by means of a formwork beam, which the Features of claim 1.

Im folgenden wird nun ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Schalungsträgers anhand der beiliegenden Zeichnungen eingehend beschrieben.In the following, a preferred embodiment of a Formwork beam according to the invention with reference to the accompanying Drawings described in detail.

Fig. 1 zeigt je einen erfindungsgemäßen Schalungsträger für Außen- und Innenschalung von oben gesehen und Fig. 2 zeigt dasselbe von der Seite ohne die vertikal angeordneten Profile. Fig. 1 shows a formwork support according to the invention for external and internal formwork seen from above and Fig. 2 shows the same from the side without the vertically arranged profiles.

Fig. 1 zeigt einen Schalungsträger für Außenschalung und Innen­ schalung aus je zwei Gliedern 1 bestehend. Die Glieder 1 bestehen in diesem Beispiel aus je vier Formrohren 2. Es könnte auch ein anderes Profil, wie zum Beispiel Winkeleisen oder U-Profil beste­ hen. Formrohre haben den Vorteil, daß sie verwindungssteif sind. Rundrohre wären auch verwindungssteif, sind aber schlecht zu ver­ arbeiten. Die in einer Ebene sich befindenden Formrohre 2 sind an den Enden mittels eines hochkant angeordneten Flacheisens 3 miteinander verbunden. Jedes Glied 1 hat an allen vier Ecken mindestens je eine Öse 4 angeschweißt. Mittels dieser Ösen sind die oberen Formrohre mit den unteren Formrohren verbunden. Ebenfalls mittels dieser Ösen 4 sind die einzelnen Glieder 1 zu einem Schalungsträger verbunden, welcher je nach Bedarf länger oder kürzer gemacht werden kann. Damit die inneren Schrauben 5 bei einer Winkelverstellung zwischen den einzelnen Gliedern 1 nicht gelockert werden müssen, sind auf dieser Seite die Flach­ eisen 3 bis Mitte Bohrung in der Öse 4 vorgezogen. Die Umstel­ lung auf einen anderen Winkel kann mit der äußeren Stellschrau­ be 6 und den daran angebrachten Muttern vollzogen werden. Dazu müssen aber die Schrauben 8, welche die vertikal angeordneten Profile mit dem Schalungsträger verbinden, gelockert werden. Zwischen den Formrohren 4, mindestens annähernd in deren Längen­ mitte erfolgt die Durchankerung. Damit der Schalungsdruck von den vertikal angeordneten Profilen auf die Durchankerung über­ tragen werden kann, ohne die Formrohre 2 auf Biegung zu über­ lasten, sind die Streben 7 angeordnet, vorzugsweise verschweißt. Fig. 1 shows a formwork support for external formwork and internal formwork consisting of two sections 1 each. In this example, the links 1 consist of four shaped tubes 2 each. There could also be a different profile, such as an angle iron or a U profile. Shaped tubes have the advantage that they are torsionally rigid. Round tubes would also be torsionally rigid, but are difficult to process. The shaped tubes 2 located in one plane are connected to one another at the ends by means of an upright flat iron 3 . Each link 1 has at least one eyelet 4 welded onto each of the four corners. The upper molded tubes are connected to the lower molded tubes by means of these eyelets. Also by means of these eyelets 4 , the individual links 1 are connected to formwork beams, which can be made longer or shorter as required. So that the inner screws 5 do not have to be loosened at an angular adjustment between the individual links 1 , the flat iron 3 are drawn to the center of the hole in the eyelet 4 on this side. The changeover to a different angle can be carried out with the outer adjusting screw 6 and the nuts attached to it. To do this, however, the screws 8 , which connect the vertically arranged profiles to the formwork beam, must be loosened. The anchoring takes place between the shaped tubes 4 , at least approximately in the middle of their lengths. The struts 7 are arranged, preferably welded, so that the formwork pressure can be transferred from the vertically arranged profiles to the anchoring without overloading the shaped tubes 2 to bend.
