Abstract

The concrete shuttering system is used for construction of a curved wall with a large radius, eg. for a settling tank. Inner and outer shuttering skins (3) may be erected so that the concrete can be poured between them to construct the wall. The inner and outer skins may be made of horizontal planks (3) held by vertical girders or posts. The planks are fastened to the posts (5) by bolts (6) parring through the planks on either side of the posts. Slots in the bolts receive wedges (8) which are dropped down vertically and push wedge pieces (7) against the flanges of the H-section posts adjacent to the planks.

Description

Grosse kreisrunde Betonmauern, wie sie z.B. für Klärbecken und dergleichen benötigt werden, werden in der Regel aus statischen und wirtschaftlichen Gründen in Segmenten geschalt und betoniert. Nach dem Aushärten des Betons von einem Bauabschnitt soll die Schalung in der Regel mittels Baukran zum nächsten Bauabschnitt versetzt werden, damit sie dort montiert werden kann. Dazu ist vorteilhaft, wenn die Schalung möglichstwenig Gewicht aufweist. Weiter ist vorteilhaft, wenn die Schalung wenig Durchankerungen benötigt. Durchankerungen sind arbeitsintensiv und die dabei entstehenden Löcher durch die Betonmauern müssen nach Beendigung des Baues abgedichtet werden.Weiter soll die Schalung mit wenig Zeitaufwand und Materialkosten auch auf der Baustelle auf andere Durchmesser eingestellt werden können.Large circular concrete walls, such as those are required for settling tanks and the like, are usually shuttered and concreted in segments for static and economic reasons. After the concrete has hardened from one construction section, the formwork should generally be moved to the next construction section using a construction crane so that it can be installed there. It is advantageous if the formwork has as little weight as possible. It is also advantageous if the formwork requires little anchoring. Anchorages are labor-intensive and the resulting holes through the concrete walls have to be sealed after completion of the construction.

Bei der erfindungsgemässen Segmentschalung wird die Schalhaut getrennt von der tragenden Konstruktion transportiert. Dies gibt in der Wahl der Schalhaut und auch in der Wahl der tragenden Konstruktion neue Möglichkeiten. Voraussetzung ist, dass die Schalhaut mittels Schnellverbindungen mit der tragenden Konstruktion verbunden und wieder gelöst werden kann. Am vorteilhaftesten sind dafür Schraubverbindungen mit einer speziellen Halterung geeignet. Die Schalhaut ist nicht nur schnell montierbar und demontierbar, sie ist auch leicht austauschbar. Als Schalhaut werden vorteilhaft dreifach verleimte oder vielfach verleimte grossflächige Schaltafeln eingesetzt.In the segment formwork according to the invention, the formwork skin is transported separately from the load-bearing structure. This opens up new possibilities in the choice of formwork skin and also in the choice of load-bearing structure. The prerequisite is that the formlining can be connected to and removed from the load-bearing structure using quick connections. The most advantageous are screw connections with a special holder. The formlining is not only quick to assemble and disassemble, it is also easy to replace. Triple-glued or multi-glued large-area formwork panels are advantageously used as formlining.

Als tragende Konstruktion fürdie Schalhautwerden doppel-T-Träger aus Stahl verwendet. Sie haben im Verhältnis zum Gewicht die höchste Tragfächigkeit. Nachdem sie mit der Schalhaut mittels Schnellverbindung verbunden sind, sind sie bei verschiedenen Höhen von zu bauenden Betonmauern leicht austauschbar.Double T-beams made of steel are used as the supporting structure for the formlining. They have the highest carrying capacity in relation to the weight. After they are connected to the formlining by a quick connection, they can be easily exchanged at different heights of the concrete walls to be built.

Im folgenden wird nun ein Ausführungsbeispiel der Erfindung anhand der beiliegenden Zeichnungen eingehend beschrieben.In the following, an embodiment of the invention will now be described in detail with reference to the accompanying drawings.

Fig. 1 zeigt einen Ausschnitt einer Aussenschalung und einer Innenschalung in perspektivischerAnsicht, Fig. 2 zeigt eine bevorzugte Schraubverbindung mit Halterung bei Montage und Fig. 3 zeigt diese Schraubverbindung fertig montiert.Fig. 1 shows a detail of an outer formwork and an inner formwork in perspective view, Fig. 2 shows a preferred screw connection with holder during assembly and Fig. 3 shows this screw connection fully assembled.

Fig. 1 zeigt einen Ausschnitt einer erfindungsgemässen Innenschalung 1 und einer Aussenschalung 2. Schalungsträger, welche in horizontaler Lage entlang der vertikal angeordneten doppel-T- Profile in mindestens zwei verschiedenen Höhen notwendig sind und durch welche normalerweise die Durchankerungen erfolgen, sind der Uebersichtlichkeit halber nicht eingezeichnet. Die Aussenschalung 2 besteht aus in regelmässigen Abständen vertikal angeordneten doppel T - Profilen aus Stahl 5 und mittels Schraubverbindungen daran befestigten Schaltafeln 3. Die Innenschalung besteht wie die Aussenschalung aus doppel- T - Profilen 5 mit daran befestigten Schaltafeln 3, wobei aber auf die Schaltafeln 3 eine Schalhaut aus vertikal angeordneten, gleichmässig breiten gehobelten Brettern 4 aufgebracht, vorzugsweise angenagelt ist.1 shows a section of an inner formwork 1 according to the invention and an outer formwork 2. Formwork girders which are necessary in a horizontal position along the vertically arranged double-T profiles at at least two different heights and through which the anchoring normally takes place are not for the sake of clarity drawn. The outer formwork 2 consists of double T profiles made of steel 5 arranged vertically at regular intervals and formwork panels 3 fastened to it by means of screw connections. Like the outer formwork, the inner formwork consists of double T profiles 5 with formwork panels 3 attached, but with the formwork panels 3 a formlining of vertically arranged, uniformly wide planed boards 4 is applied, preferably nailed.

Fig. 2 zeigt eine bevorzugte Schraubverbindung während der Montage. Im Steg der Profile 5 sind genügend Löcher 7 für die Aufnahme der Verbindungsstücke 6 vorgesehen. Solche Löcher sind preisgünstig mittels Stanzen herstellbar. Sie verursachen keine Stabilitätsminderung der Profile 5. Weiters kann die Verschraubung mit der Schalhaut wahlweise auf der einen oder auf der anderen Seite der Profi le 5 vorgenommen werden. Die Verbindungsstücke 6 können als Gussteil oder in Stahl hergestellt und bebeliebig oft verwendet werden.Fig. 2 shows a preferred screw connection during assembly. Sufficient holes 7 are provided in the web of the profiles 5 for receiving the connecting pieces 6. Such holes are inexpensive to produce by punching. They do not reduce the stability of the profiles 5. Furthermore, the screws can be screwed to the formlining either on one or on the other side of the Profi le 5. The connecting pieces 6 can be produced as a cast part or in steel and can be used as often as desired.

Fig. 3 zeigt die Schraubverbindung fertig montiert. Als Schrauben werden vorzugsweise Flachkopfschrauben 8 verwendet.Fig. 3 shows the screw connection fully assembled. Flat-head screws 8 are preferably used as screws.
