Description

Die Erfindung betrifft eine Einrichtung zum Verspannen von Schalungsteilen an einer Schalungslehre bzw. an zu fertigenden oder bereits gefertigten Bauabschnitten. Zur Errichtung von Bauwerken, insbesondere bei der Herstellung von Betonwänden müssen die Schalungsteile an eine Schalunrslehre bzw. bei einem abschnittweisen Herstellen von Bauabschnitten an bereits bestehende Bauabschnitte angepreßt werden. In der Regel wird dies insbesondere bei Rundbauten so gehandhabt, daß in entsprechenden Abständen Spannkeile eingetrieben werden, so daß die Schalungsteile in horizontaler Richtung entsprechend vorgespannt werden, damit sie dann an die Schalungslehre bzw. den gefertigten Bauabschnitt angedrückt werden. Gerade bei der Herstel- lunG von runden bzw. kreisförmigen Bauwerken ergeben sich oft Schwierigkeiten, da die Reibung zwischen den Schalungsteilen und bereits bestehenden Bauabschnitten sehr groß ist, so daß eine ordnungsgemäße Verspannung fast unmöglich wird. Insbesondere bei der Verwendung von Schalungsteilen aus Holz ergeben sich hier Schwierigkeiten.The invention relates to a device for bracing formwork parts on a formwork jig or on construction sections that are to be manufactured or that have already been manufactured. To erect buildings, in particular when manufacturing concrete walls, the formwork parts have to be pressed against a formwork jig or, in the case of section-by-section manufacture of construction sections, against existing construction sections. As a rule, this is handled in particular in the case of round buildings in such a way that clamping wedges are driven in at appropriate intervals, so that the formwork parts are prestressed accordingly in the horizontal direction so that they are then pressed onto the formwork jig or the finished construction section. G lun especially in the manufacture of round or circular structures often difficulties arise because the friction between the mold parts and existing construction phases is very large, so that a proper tension is almost impossible. Difficulties arise in particular when using wooden formwork parts.

Die Erfindung hat sich zur Aufgabe gestellt, eine Einrichtung zum Verspannen von Schalungsteilen zu schaffen, mit der diese Nachteile behoben werden können und mit welcher ein einwandfreies Verspannen ermöglicht wird.The invention has for its object to provide a device for bracing formwork parts with which these disadvantages can be remedied and with which a perfect bracing is made possible.

Diese erfindungsgemäße Einrichtung ist gekennzeichnet durch einen zwischen die der Schalfläche der Schalungsteile abgewandte Außenfläche und ein festes Widerlager einlegbaren, pneumatisch oder hydraulisch aufblähbaren Schlauch.This device according to the invention is characterized by a hose which can be inserted pneumatically or hydraulically between the outer surface facing away from the formwork surface of the formwork parts and a fixed abutment.

Nach dem Einrichten der Schalungsteile muß dann lediglich noch der eingelegte Schlauch pneumatisch oder hydraulisch aufgebläht werden, so daß auf die ganze Schalungslänge ein gleichmäßiger Anpreßdruck gewährleistet ist. Es ist dadurch nicht mehr nötig, daß sich die einzelnen Schalungsteile entlang der Schalungslehre bzw. fertiger Bauabschnitte verschieben müssen, sondern es wird auf die ganze Länge der errichteten Schalung senkrecht zur Schalung ein entsprechender Druck ausgeübt. Es ergibt sich dadurch nicht nur eine einwandfreie Anpreßkraft, sondern es wird dadurch auch die Schalungsarbeit wesentlich erleichtert. Das relativ mühsame Anspannen durch Einschlagen von Spannkeilen kann durch einfaches Einschalten einer Pumpe ersetzt werden, welche den nötigen Druck in den Schlauch einbringt.After setting up the formwork parts, the only thing left to do is to insert the pneumatic or hy hose be inflated drastically, so that a uniform contact pressure is guaranteed over the entire length of the formwork. It is therefore no longer necessary that the individual formwork parts have to move along the formwork jig or finished construction sections, but instead a corresponding pressure is applied to the entire length of the erected formwork perpendicular to the formwork. This not only results in a perfect contact pressure, it also makes the formwork considerably easier. The relatively tedious tightening by driving in clamping wedges can be replaced by simply switching on a pump, which brings the necessary pressure into the hose.

Weitere erfindungsgemäße Merkmale und besondere Vorteile werden in der nachstehenden Beschreibung anhand der Zeichnung noch näher erläutert. Es zeigen: Fig. 1 einen Vertikalschnitt durch eine Schalung, welche an einem bereits bestehenden Bauabschnitt angesetzt ist; Fig. 2 vergrößert dargestellt ein Ausführungsbeispiel der erfindungsgemäßen Einrichtung; Fig. 3 einen Teilabschnitt der Einrichtung bei einer Rundschalung; Fig. 4 ebenfalls einen Teilabschnitt der Einrichtung in Draufsicht; wobei hier die Schalung an einen bestehenden Bauabschnitt angesetzt ist.Further features according to the invention and special advantages are explained in more detail in the following description with reference to the drawing. 1 shows a vertical section through a formwork which is attached to an already existing construction phase; Fig. 2 shows an embodiment of the device according to the invention enlarged; Figure 3 shows a partial section of the device in a circular formwork. 4 also shows a partial section of the device in plan view; where the formwork is attached to an existing construction phase.

Bekanntlich müssen die Schalungsteile 1 und 2, welche als Schalungstafeln oder einzelne Bretter ausgebildet sein können, an einer entsprechenden Schalungslehre, welche den Abstand der beiden Schalungsteile 1 und 2 ergibt oder an zu fertigenden bzw. bereits gefertigten Bauabschnitten 3 angepreßt werden. Der untere Rand dieser Schalungsteile 1 und 2 nuß also bei der Ausgestaltung gemäß Fig. 1 an den fertigen Bauabschnitt 3 angepreßt werden, so daß der nächste Bauabschnitt betoniert werden kann. Selbstverständlich können hier die verschiedensten Schalungssysteme angewandt werden, wobei mehrere Schalungsteile 1 und 2 durch Längsträger 4 zusammengehalten werden können.As is known, the formwork parts 1 and 2, which can be designed as formwork panels or individual boards, must be pressed against a corresponding formwork gauge, which results in the distance between the two formwork parts 1 and 2, or against construction sections 3 that are to be produced or have already been produced. The lower edge of these formwork parts 1 and 2 must therefore be pressed against the finished construction section 3 in the embodiment according to FIG. 1, so that the next construction section can be concreted. Self ver Of course, a wide variety of formwork systems can be used here, several formwork parts 1 and 2 being held together by longitudinal beams 4.

Gemäß der vorliegenden Erfindung wird nun ein pneumatisch oder hydraulisch aufblähbarer Schlauch 5 vorgesehen, welcher zwischen die Außenfläche 6 der Schalungsteile 1 bze. 2 und ein festes Widerlager in Form einer Profilschiene 7 eingelegt wird. Zweckmäßig wird hier eine Profilschiene7 vorgesehen, welche auf der den Schalungsteilen 1, 2 zugewandten Längsseite offen ausgeführt ist. Ferner ist diese Profilschiene 7 möglichst biegesteif ausgebildet, um dadurch einen entsprechenden, senkrecht zu den Schalungsteilen 1 und 2 wirkenden Druck aufnehmen zu können. Die zweckmäßigste Ausführungsform für die Profilschiene 7 ist ein U-förmiger Querschnitt, wie dies insbesondere der Fig. 2 entnommen werden kann. Der in die Profilschiene ? eingesetzte Schlauch 5 besitzt dann zweckmäßigerweise einen rechteckigen Querschnitt, so daß bei Einführen des Druckmediums dieser Schlauch 5 nur noch nach einer Seite hin, nämlich zur offenen Profilseite hin sich ausdehnen kann. Selbstverständlich könnte auch ein im Querschnitt kreisförmiger Schlauch angewandt werden, doch ist dann zur Erreichung eines entsprechenden Anpreßdruckes wesentlich mehr Druckmedium erforderlich, weil ja zudem immer auch noch der komplette Raum innerhalb der Profilschiene 7 angefüllt werden muß- In diesem Zusammenhang wäre auch eine Ausführung denkbar, bei welcher die Profilschiene ? einen annähernd C-förmigen Querschnitt aufweist.According to the present invention, a pneumatically or hydraulically inflatable hose 5 is now provided, which bze between the outer surface 6 of the formwork parts. 2 and a fixed abutment in the form of a profile rail 7 is inserted. A profile rail 7 is expediently provided here, which is designed to be open on the longitudinal side facing the formwork parts 1, 2. Furthermore, this profile rail 7 is designed to be as rigid as possible in order to be able to absorb a corresponding pressure acting perpendicular to the formwork parts 1 and 2. The most expedient embodiment for the profile rail 7 is a U-shaped cross section, as can be seen in particular from FIG. 2. The one in the profile rail? The hose 5 used then expediently has a rectangular cross section, so that when the pressure medium is introduced, this hose 5 can only expand to one side, namely to the open profile side. Of course, a hose with a circular cross section could also be used, but then much more pressure medium is required to achieve a corresponding contact pressure, because the entire space within the profile rail 7 must also still be filled. In this connection, an embodiment would also be conceivable. in which the profile rail? has an approximately C-shaped cross section.

Die erfindungsgemäße Ausführun eignet sich besonders bei der Herstellung von bogen-, insbesondere kreisförmigen Bauten. Die Profilschiene 7 kann dannnahe der Außenfläche 6 der Schalungsteile 1, 2 verlaufend angeordnet werden, wobei diese umfangsgeschlossene Profilschiene 7 lediglich an den Schalungsteilen 1 und 2 aufgehängt werden muß. Zu diesem Zweck können an den Schalungsteilen 1 und 2 entsprechende Haken 8 vorgesehen werden, in welchen über Verbindungsstangen 9 die Profilschiene 7 eingehängt wird. Es werden hier keine Streben zum Zentrum hin benötigt, da diese Profilschiene 7 lediglich auf Druck beansprucht wird, zumal ja umfangsgeschlossen auf die Profilschiene 7 die gleiche Belastung auftritt. Es stellen sich dadurch keine Biegekräfte ein. Die erfindungsgemäße Einrichtung kann daher gerade bei Rundbauten ohne besonderen konstruktiven Aufwand eingesetzt werden. Bei der Außenschalung eines Rundbaues wird die Profilschiene 7 selbstverständlich dann auf Zug beansprucht, so daß auch hier keine zusätzlichen Abstützungen oder Verstrebungen erforderlich sind.The embodiment according to the invention is particularly suitable for the production of arched, in particular circular, structures. The profile rail 7 can then be arranged near the outer surface 6 of the formwork parts 1, 2, said circumferentially closed profile rail 7 being single Lich must be hung on the formwork parts 1 and 2. For this purpose, corresponding hooks 8 can be provided on the formwork parts 1 and 2, in which the profiled rail 7 is suspended via connecting rods 9. No struts towards the center are required here, since this profile rail 7 is only subjected to pressure, especially since the same load occurs on the profile rail 7 when it is circumferentially closed. As a result, there are no bending forces. The device according to the invention can therefore be used in particular in the case of round buildings without any particular design effort. In the outer formwork of a circular structure, the profile rail 7 is of course then subjected to tension, so that here, too, no additional supports or struts are required.

Damit die Profilschiene 7 zum Transport zerlegt werden kann, besteht diese aus einzelnen Profilstücken 7', welche über Flansche 10 miteinander verbunden werden können.So that the profile rail 7 can be disassembled for transport, it consists of individual profile pieces 7 'which can be connected to one another via flanges 10.

Der Schlauch 5 muß lediglich an eine entspfechende Pumpe angeschlossen werden, damit nach dem Versetzen der Schalungsteile 1 und 2 das Druckmedium dem Schlauch 5 zugeführt werden kann. Das Aufblähen des Schlauches 5 kann durch Druckluft oder eine entsprechende Flüssigkeit erfolgen. Da der Schlauch 5 nach außen hin durch die Profilschiene abgedeckt ist, kann dieser auch nicht durch einen rauhen Baustellenbetrieb beschädigt werden, da er ja auch beim Weiterziehen der Schalung zum nächsten Bauabschnitt in dieser geschützten StellunG verbleibt.The hose 5 only has to be connected to a corresponding pump so that the pressure medium can be supplied to the hose 5 after the formwork parts 1 and 2 have been moved. The tube 5 can be inflated by compressed air or an appropriate liquid. Since the hose 5 is covered on the outside by the profile rail, it cannot be damaged by rough construction site operation, since it remains in this protected position even when the formwork is moved on to the next construction phase.

Die Errichtung des ersten Bauabschnittes kann auch ohne Schalungslehre ausgeführt werden. Zu diesem Zweck werden die Schalungen entsprechend der gewünschten Gebäudeform aufgestellt und der Zwischenraum wird dann mit Beton gefüllt. Entsprechend der Füllhöhe des Betons innerhalb der SchalunG wird der Anpreßdruck an die Schalung, also der Druck im Schlauch 5, erhöht, so daß sich die Lage der Schalungsteile nicht verändern kann.The construction of the first construction phase can also be carried out without a formwork gauge. For this purpose, the formwork is made according to the desired building shape set up and the space is then filled with concrete. Depending on the level of the concrete within the formwork, the contact pressure to the formwork, ie the pressure in the hose 5, is increased so that the position of the formwork parts cannot change.

Bei Anwendung der Einrichtung zur Herstellung von ebenen Wänden muß das Widerlager, welches auch dort in Form einer Profilschiene ausgeführt werden kann, mit entsprechenden Verstrebungen versehen werden, damit ein gleichmäßiger Anpreßdruck gewährleistet ist. Außerdem ist zusätzlich eine feste Absatzmöglichkeit für das Widerlager zu schaffen. Es kann also zum Beispiel eine Abstützung an einer gegenüberliegenden Wand erfolgen oder aber die beiden Widerlager der inneren und äußeren Schalung werden durch Zugstreben miteinander verbunden. Bei bereits betonierten Abschnitten kann auch eine Verbindung durch in den Beton eingelassene Anker erfolgen, so daß zwischen dem Widerlager und der Schalung ein genügender Druck im Schlauch aufgebaut werden kann. Am vorteilhaftesten ist aber der Einsatz der erfindungsgemäßen Einrichtung bei Rundbauten, beispielsweise bei der Herstellung von Silos, Rundställen, Jauchegruben, Faulbehältern usw.When using the device for the production of flat walls, the abutment, which can also be designed there in the form of a profile rail, must be provided with corresponding struts so that a uniform contact pressure is ensured. In addition, a fixed sales opportunity for the abutment must be created. For example, it can be supported on an opposite wall or the two abutments of the inner and outer formwork are connected to each other by tension struts. In the case of sections that have already been concreted, a connection can also be made by anchors embedded in the concrete, so that a sufficient pressure can be built up in the hose between the abutment and the formwork. However, the most advantageous is the use of the device according to the invention in round buildings, for example in the manufacture of silos, round stables, liquid manure pits, digesters, etc.

Das Widerlager kann selbstverständlich auch andere Art und Weise gebildet werden als durch eine Profilschiene. Beispielsweise könnte auch eine entsprechende Aufnahmenut für den Schlauch 5 an einem entsprechenden Arbeitspodest angebracht werden, welches jeweils mit der Schalung nach oben gezogen wird. Diese Einrichtung ist sowohl beim ersten Bauabschnitt als auch beim Ansetzen an bereits gefertigten Bauabschnitten einsetzbar. Gerade beim Übergang zwischen zwei Bauabschnitten wird so ein einwandfreies.Anpressen gewährleistet, so daß es stets zu einem glatten Übergang kommt.The abutment can of course also be formed in a different way than by a profile rail. For example, a corresponding receiving groove for the hose 5 could also be attached to a corresponding working platform, which is pulled up with the formwork in each case. This device can be used both in the first construction phase and when starting on construction phases that have already been manufactured. A perfect pressing is guaranteed, especially at the transition between two construction phases, so that there is always a smooth transition.
