Abstract

In a known aligning clamp, the two claws (3, 4) are situated at a virtually invariable distance from one another which is adapted to the thickness of the outer crossbeams of shuttering-panel frames, so that the aligning clamp (1) is only suitable for holding together and mutually aligning directly abutting shuttering panels (14, 18). In contrast, the new aligning clamp is to be able to hold together and mutually align shuttering panels even when compensating pieces (16) are situated between the shuttering panels. In the new aligning clamp, one of the two claws (4) is mounted such that it is displaceable in the axial direction of the crossmember of the aligning clamp and fixable to this crossmember in a variable position. This design of the aligning clamp makes it possible roughly to preset the basic distance between the two claws, intended for drawing together and clamping shuttering panels, in accordance with the section to be bridged in each case, before the aligning clamp is attached to the shuttering panels to be drawn together and is tightened into the gripping position. <IMAGE>

Description

Die Erfindung betrifft eine für Schalungssysteme bestimmte Richtzwinge, welche eine hohlkastenartig ausgebildete Traverse und zwei an der Traverse einander gegenüber angeordnete, gegeneinander anstellbare Klauen aufweist, von denen eine um eine feststehende Achse mittels einer Stellspindel verschwenkbar an der Traverse gelagert ist.The invention relates to a straightening clamp intended for formwork systems, which has a hollow box-like crossmember and two mutually opposing claws arranged on the crossmember, one of which is pivotably mounted on the crossbar about a fixed axis by means of an adjusting spindle.

Derartige Richtzwingen verwendet man, um benachbarte Schaltafeln eines Schalungssystemes zusammenzuklammern und außerdem gegeneinander auszurichten, damit deren Schalflächen in Flucht zueinander gebracht werden. Die Richtzwinge wird dabei an die Rückseite benachbarter Schaltafeln angesetzt, wobei sich die Oberseite der Traverse gegen Streben oder sonstige Aussteifungselemente der Rahmen der benachbarten Schaltafeln legt, während die Klauen mit ihren freien, über die Traverse überstehenden Enden in entsprechend geformte Ausnehmungen an der Innenseite der nebeneinander liegenden Holme der Rahmen der benachbarten Schaltafeln eingreifen.Such straightening clamps are used to clamp together adjacent formwork panels of a formwork system and also to align them with each other so that their formwork surfaces are brought into alignment with one another. The straightening clamp is attached to the back of adjacent formwork panels, with the top of the crossbeam laying against struts or other stiffening elements of the frame of the adjacent formwork panels, while the claws with their free ends projecting beyond the crossbeam form correspondingly shaped recesses on the inside of the side by side the horizontal spars of the frames of the neighboring formwork panels.

Bei einer bekannten Richtzwinge der eingangs genannten Gattung (EP-A-O 201 887 befinden sich die beiden Klauen in praktisch unveränderbarem Abstand voneinander, wobei der Abstand der Klauen auf die Dicke der äußeren Holme oder Leisten der Schaltafelrahmen abgestellt ist. Dementsprechend kann man mit einer derartigen Richtzwinge zwar unmittelbar aneinanderstoßende Schaltafeln zusammenhalten und gegeneinander ausrichten, jedoch ist es nicht möglich, Ausgleiche zu überbrücken, die aus schalungstechnischen Gründen in die Schalung eingebaut werden müssen. Da die Dimensionen von mittels Schalungen zu erstellenden Bauwerken nicht exakt auf vorhandene Schaltafelgrößen abgestimmt sind, ist es beim Einschalen häufig notwendig, sogenannte Ausgleichsstücke zwischen benachbarte vorgefertigte Schaltafeln einzubauen, die im allgemeinen erst auf der Baustelle zugeschnitten werden.In a known straightening clamp of the type mentioned at the outset (EP-AO 201 887), the two claws are at a practically unchangeable distance from one another, the spacing of the claws being based on the thickness of the outer spars or strips of the formwork panel frame Although it is necessary to hold together adjoining formwork panels and align them against each other, it is not possible to bridge compensations that have to be built into the formwork for formwork-related reasons Formwork often necessary to install so-called compensation pieces between adjacent prefabricated formwork panels, which are generally only cut to size on the construction site.

Bei einer anderen bekannten Klemmvorrichtung zum Verbinden von Schaltafeln (DE-A-33 08 528) ist es notwendig, zum Verstellen einer entlang einer Traverse einstellbaren Pratze einen diese Pratze über ein Lochraster mit der Traverse verbindbaren Steckbolzen aus einem Loch des Loch-Rasters herauszuziehen, so daß die Pratze von der Traverse vollständig gelöst wird und die dann einzelnen Teile verlegt oder verloren gehen können. Die Bohrungen des Loch-Rasters erfordern, daß die miteinander zu verbindenden Schaltafeln entweder unmittelbar oder über auf das Loch-Raster abgestellten Ausgleichsstücken untereinander verbunden werden.In another known clamping device for connecting formwork panels (DE-A-33 08 528) it is necessary, in order to adjust a claw that can be adjusted along a crossbar, to pull out a claw pin that can be connected to the crossbar from a hole in the hole grid via a hole pattern, so that the claw is completely detached from the crossbeam and the individual parts can then be misplaced or lost. The holes in the hole grid require that the formwork panels to be connected to one another are connected to one another either directly or via compensating pieces placed on the hole grid.

Der Erfindung liegt die Aufgabe zugrunde, eine Richtzwinge für Schalungssysteme zu schaffen, mit der benachbarte Schalelemente wie Schaltafeln zusammengezogen und ausgerichtet werden können, und zwar sowohl wenn diese Schalelemente unmittelbar aneinander anstoßen als auch wenn zwischen diese benachbarten Schalelemente Längenausgleichselemente eingebaut sind.The invention has for its object to provide a straightening clamp for formwork systems with which adjacent formwork elements such as formwork panels can be pulled together and aligned, both when these formwork elements directly abut each other and when length compensation elements are installed between these adjacent formwork elements.

Diese Aufgabe wird erfindungsgemäß mit einer Richtzwinge der eingangs genannten Gattung gelöst, welche die kennzeichnenden Merkmale des Patentanspruches 1 aufweist. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved with a straightening clamp of the type mentioned, which has the characterizing features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Bei der erfindungsgemäßen Richtzwinge ist eine der beiden Klauen nicht in fester, sondern in variabler Position an der Traverse angebracht. Diese Klaue ist beispielsweise mittels eines Zapfens in ein Lochraster absteckbar, so daß sich ein variabler Abstand zu der anderen, von einer Stellspindel um eine unveränderbare Drehachse verschwenkbar gelagerten Klaue den jeweiligen Bedürfnissen entsprechend einstellen läßt. Die Verstellung der einen Klaue mittels Zapfen und Lochraster ist einfach durchzuführen und geeignet, die erforderlichen Kräfte zu übertragen, ohne daß Beschädigungen im rauhen Baustellbetrieb zu befürchten wären.In the straightening clamp according to the invention, one of the two claws is not attached to the crossbar in a fixed but in a variable position. This claw can be pinned, for example, by means of a pin in a hole pattern, so that a variable distance from the other claw, which is pivotably mounted by an adjusting spindle about an unchangeable axis of rotation, can be adjusted according to the respective requirements. The adjustment of one claw by means of a peg and hole pattern is easy to carry out and is suitable for transmitting the necessary forces without fear of damage in the rough construction site operation.

Bei der erfindungsgemäßen Richtzwinge sind alle Funktionen einer Richtzwinge erhalten, nämlich die Fähigkeit, zwei benachbarte Schalelemente zusammenziehen und ausrichten zu können. Wegen der Verstellbarkeit der einen der beiden Klauen in unterschiedliche Positionen entlang der Traverse ist es zusätzlich möglich, Ausgleiche, die zwischen benachbarte Schalelemente eingebaut sind, zu überbrücken und auch derartige Ausgleiche bzw. Ausgleichseinbauten durch Festziehen der Richtzwinge an den beidseits benachbarten Schalelementen in die Schalung einzuspannen und ebenfalls dabei auszurichten. Die erfindungsgemäße Richtzwinge ist dementsprechend vielseitiger verwendbar als bisher für derartige Zwecke bekannte Richtzwingen.With the straightening clamp according to the invention, all functions of a straightening clamp are retained, namely the ability to pull together and align two adjacent formwork elements. Due to the adjustability of one of the two claws in different positions along the crossmember, it is also possible to bridge compensations that are installed between adjacent formwork elements and to also clamp such compensations or compensating internals into the formwork by tightening the straightening clamp on the formwork elements that are adjacent on both sides and also align it. The straightening clamp according to the invention is accordingly more versatile than previously known straightening clamps for such purposes.

In der Zeichnung ist ein Ausführunsbeispiel einer erfindungsgemäßen Richtzwinge dargestellt, und zwar zeigt

  • Figur 1 eine schaubildliche Ansicht dieser Richtzwinge schräg von unten gesehen,
  • Figur 2 eine Seitenansicht der Richtzwinge aus Figur 1, die an zwei benachbarte Schaltafeln, zwischen denen sich ein Ausgleichselement befindet, angebaut ist,
  • Figur 3 eine Seitenansicht der Richtzwinge aus Figur 1 und 2 in vergrößertem Maßstab, wobei Einzelheiten deutlicher zu erkennen sind, und
  • Figur 4 eine Draufsicht auf die Oberseite der Richtzwinge gemäß Figur 3.
In the drawing, an exemplary embodiment of a straightening clamp according to the invention is shown and shows
  • FIG. 1 is a perspective view of this straightening clamp seen obliquely from below,
  • FIG. 2 shows a side view of the straightening clamp from FIG. 1, which is attached to two adjacent formwork panels, between which a compensating element is located,
  • 3 shows a side view of the straightening clamp from FIGS. 1 and 2 on an enlarged scale, details being more clearly recognizable, and
  • FIG. 4 shows a top view of the top of the straightening clamp according to FIG. 3.

Die Richtzwinge (1) hat eine langgestreckte Traverse (2) mit U-förmigem Querschnitt, wobei sich die offene Seite dieser U-förmigen Traverse (2) oben befindet, so daß die Traverse nach unten bzw. zur in der Montageproduktion außen liegenden Seite geschlossen ist, wie insbesondere Figur 1 zeigt.The straightening clamp (1) has an elongated crossmember (2) with a U-shaped cross section, the open side of this U-shaped crossmember (2) being at the top, so that the crossmember is closed at the bottom or to the side on the outside in assembly production is, as shown in Figure 1 in particular.

An der Traverse (2) sind zwei Klauen (3, 4) gelagert, wobei die Klaue (3) um eine quer zur Längsachse der Traverse verlaufende feststehende Achse (5) verschwenkbar innerhalb der Traverse (2) gelagert ist, während die Klaue (4) in Längsrichtung der Traverse (2) begrenzt verschiebbar auf diese aufgesteckt ist und in variabler Position an der Traverse (2) festgelegt werden kann, was weiter unten im einzelnen beschrieben ist.Two claws (3, 4) are mounted on the crossmember (2), the claw (3) being mounted within the crossmember (2) so as to be pivotable about a fixed axis (5) running transversely to the longitudinal axis of the crossbar, while the claw (4 ) in the longitudinal direction of the crossmember (2) is slidably attached to it and can be fixed in variable position on the crossmember (2), which is described in detail below.

Während die Klaue (4) von Hand in die jeweils gewünschte Betriebsposition zu bewegen und einzusetzen ist und dann in dieser Position unverändert verbleibt, dient zum Verschwenken der anderen Klaue (3) eine Stellspindel (6), mit deren Hilfe diese Klaue (3) verschwenkt und die zum Festziehen und Ausrichten benachbarter Schalelemente benötigte Kraft aufgebracht werden kann.While the claw (4) is to be moved and used by hand in the desired operating position and then remains unchanged in this position, an adjusting spindle (6) is used to pivot the other claw (3), with the aid of which this claw (3) pivots and the force required to tighten and align adjacent formwork elements can be applied.

Auf der Oberseite der Traverse (2) befinden sich an den Enden über die Längsseiten der Traverse überstehende Auflagerbleche (7, 8), welche die Richtfläche der Richtzwinge bilden. Im mittleren Bereich befindet sich ein weiteres Auflagerblech (9), das ebenfalls über die Längsseiten der Traverse (2) übersteht. Die Klaue (4) ist zwischen den Auflagerblechen (7 und 9) auf der Traverse (2) verschiebbar und, da die Auflagerbleche (7 und 9) seitlich über die Traverse (2) überstehen, unverlierbar auf der Traverse (2) angebracht.On the upper side of the crossmember (2) there are support plates (7, 8) projecting over the long sides of the crossmember, which form the straightening surface of the straightening clamp. In the middle area there is another support plate (9) which also protrudes over the long sides of the crossbeam (2). The claw (4) is between the support plates (7 and 9) can be moved on the crossbar (2) and, since the support plates (7 and 9) protrude laterally over the crossbar (2), they are captively attached to the crossbar (2).

Wie Figur 2 zeigt, greifen in der Montageposition die Klauen (3, 4) der Richtzwinge (1) in sickenförmige Vertiefungen (10) an der Innenseite der Randholme (11) der Rahmen (12) benachbarter Schaltafeln (13, 14) einer hier nur ausschnittsweise dargestellten Schalung ein. Zwischen den beiden Schaltafeln (13, 14) ist ein Ausgleichselement (15) eingebaut, das aus Holzleisten (16) und einer auf diesen aufliegenden Schalhaut (17) zusammengebaut ist. Während die Schaltafeln (13 und 14) vorgefertigte Schalelemente sind, werden Ausgleichselemente wie das Ausgleichselement (15) zweckmäßig auf der Baustelle den entsprechenden Bedürfnissen entsprechend zugeschnitten, um Längen- bzw. Breitenausgleiche einer Schalung herbeizuführen. Die Schalhaut (17) derartiger Ausgleichselemente (15) soll mit den Schalhäuten (18) der an das Ausgleichselement anschließenden Schaltafeln (13, 14) fluchten, so daß die Richtzwinge (1) nicht nur die Schaltafeln (13 und 14), sondern auch das im vorliegenden Falle zwischen diese eingebaute Ausgleichselement (15) beim Festziehen ausrichtet.As Figure 2 shows, in the assembly position, the claws (3, 4) of the straightening clamp (1) engage in bead-shaped depressions (10) on the inside of the edge rails (11) of the frames (12) of adjacent formwork panels (13, 14) only here cut-out formwork shown. A compensating element (15) is installed between the two formwork panels (13, 14), which is assembled from wooden strips (16) and a formlining (17) resting on them. While the formwork panels (13 and 14) are prefabricated formwork elements, compensating elements such as the compensating element (15) are expediently tailored to the corresponding needs on the construction site in order to bring length and width compensation of a formwork. The formlining (17) of such compensating elements (15) is to be aligned with the formwork skins (18) of the formwork panels (13, 14) adjoining the compensating element, so that the straightening clamp (1) not only the formwork panels (13 and 14), but also that aligns in the present case between these built-in compensation element (15) when tightening.

Aus Figur 3 und 4 sind Einzelheiten der Richtzwinge (1) deutlicher zu erkennen.Details of the straightening clamp (1) can be seen more clearly from FIGS. 3 and 4.

Die Klaue (3) ist in Seitenansicht winkelförmig ausgebildet und hat an ihrem in der Traverse (2) liegendem Ende ein Auge (19) mit Innengewinde, in das der mit entsprechendem Außengewinde versehene Schaft (20) der Stellspindel (6) eingeschraubt ist. Die Stellspindel ist außerdem mit einem als Flügelmutter ausgebildetem Kopf (21) versehen, der auf einer Unterlegscheibe (22) derart aufliegt, daß die Stellspindel (6) beim Verstellen der Klaue (3) begrenzte Pendelbewegungen ausführen kann, um den Bewegungen des Auges (19) der Klaue (3) folgen zu können. Eine Öffnung (23) in der Seitenwand der Traverse (2) ermöglicht es, die Position des Auges (19) von außen zu beobachten.The claw (3) is angled in side view and has an eye (19) with an internal thread at its end lying in the crossmember (2), into which the shaft (20) of the adjusting spindle (6) provided with the corresponding external thread is screwed. The adjusting spindle is also provided with a head (21) designed as a wing nut, which rests on a washer (22) in such a way that the adjusting spindle (6) can perform limited pendulum movements when adjusting the claw (3) in order to compensate for the movements of the eye (19 ) to be able to follow the claw (3). An opening (23) in the side wall of the crossmember (2) makes it possible to observe the position of the eye (19) from the outside.

Zwischen den Auflagerblechen (7 und 9) ist auf die nach oben offene Oberseite der Traverse (2) ein Abdeckblech (24) aufgesetzt, daß mit den Auflagerblechen (7 und 9) in einer Ebene liegt und somit eine zusätzliche Auflagerfläche bildet, die zum Ausrichten von Ausgleichselementen wie das Ausgleichselement (15) gemäß Figur 2 benutzt werden kann.Between the support plates (7 and 9), a cover plate (24) is placed on the open top of the crossmember (2) that lies with the support plates (7 and 9) in one plane and thus an additional Forms a bearing surface, which can be used to align compensation elements such as the compensation element (15) according to FIG. 2.

Das Abdeckblech (24) enthält in Längsrichtung der Traverse (2) eine Reihe von Löchern (25), welche ein Lochraster bilden. In jedes der Löcher (25) des Lochrasters läßt sich ein in der Klaue (4) befindlicher Stift (26) einstecken, um die jeweils gewünschte Position der Klaue (4) entlang der Traverse (2) einzustellen.The cover plate (24) contains a series of holes (25) in the longitudinal direction of the cross member (2), which form a hole pattern. A pin (26) located in the claw (4) can be inserted into each of the holes (25) of the hole pattern in order to set the desired position of the claw (4) along the crossmember (2).

Die Traverse (2) weist zwei plattenförmige Wangen oder Backen (27 und 28) auf, die in einem derartigen Abstand voneinander liegen, daß die Klaue (4) mit ausreichendem seitlichen Spiel auf die Traverse (2) aufgesteckt ist und entlang der Traverse (2) verschoben werden kann, wenn sich der Stift (26) nicht in einem Loch (25) des Lochrasters befindet. Der Stift (26) ist an einer Verbindungsplatte (29) befestigt, die zwischen den Backen (27 und 28) nahe dem oberen Ende der Klaue (4) befestigt ist und welche mit einem abgewinkelten Abschnitt (30) die Spann- und Arbeitsfläche der Klaue (4) bildet. Der Stift (26) befindet sich dabei - in Figur 3 und 4 gesehen - nahe dem äußersten linken Ende der Klaue (4).The crossmember (2) has two plate-shaped cheeks or jaws (27 and 28) which are spaced from one another in such a way that the claw (4) is plugged onto the crossmember (2) with sufficient lateral play and along the crossmember (2nd ) can be moved if the pin (26) is not in a hole (25) of the hole pattern. The pin (26) is fastened to a connecting plate (29) which is fastened between the jaws (27 and 28) near the upper end of the claw (4) and which has an angled section (30) the clamping and working surface of the claw (4) forms. The pin (26) is located - seen in Figures 3 and 4 - near the extreme left end of the claw (4).

Die entgegengesetzten Enden der Backen (27, 28) der Klaue (4) sind über einen quer zur Traverse (2) sich erstreckenden Bolzen (31) untereinander verbunden, der sich gegen die geschlossene Unterseite (2a) der Traverse (2) legt. Somit umschließt die Klaue (4) die Traverse (2) vollständig nach Art eines Hohlkastens und ist dementsprechend unverlierbar auf der Traverse (2) angeordnet.The opposite ends of the jaws (27, 28) of the claw (4) are connected to one another via a bolt (31) which extends transversely to the crossmember (2) and lies against the closed underside (2a) of the crossmember (2). The claw (4) thus completely surrounds the crossmember (2) in the manner of a hollow box and is accordingly captively arranged on the crossmember (2).

Der Bolzen (31) befindet sich nahe dem - in Figur 3 und 4 gesehen - rechten Ende der Klaue (4) und somit auf der entgegengesetzten Seite des Schwerpunktes dieser Klaue wie der Stift (26). Daher besteht die Tendenz, daß die Klaue (4) aufgrund ihres Eigengewichtes in die in Figur 3 erkennbare, leicht nach hinten geneigte Position und damit in die Rastposition fällt, wenn sie losgelassen wird. Zum Verstellen der Klaue (4) wird diese - in Figur 3 gesehen - nach rechts gekippt, wobei der Stift (26) aus dem Lochraster herausgehoben wird, während der Bolzen (31) weiterhin in Anlage an der Unterseite (2a) der Traverse (2) bleibt. Die Klaue (4) kann dann in die jeweils gewünschte Betriebsposition eingestellt werden, was zweckmäßig bei der Montage der Richtzwinge an benachbarten Schalelementen erfolgt. Auch wenn die Richtzwinge (1) in der in Figur 1 erkennbaren Position montiert wird, was normalerweise der Fall sein dürfte, rastet die Klaue (4) aus der eingestellten Position nicht unbeabsichtigt aus, insbesondere wenn die Klaue bereits an den Rahmen einer Schaltafel angesetzt worden ist.The bolt (31) is located near the right end of the claw (4), as seen in FIGS. 3 and 4, and thus on the opposite side of the center of gravity of this claw as the pin (26). Therefore, there is a tendency that the claw (4) falls due to its own weight in the position shown in Figure 3, slightly inclined backwards and thus in the locking position when released. To adjust the claw (4), it is tilted to the right, as seen in FIG ) remains. The claw (4) can then be set in the desired operating position, which is useful when mounting the straightening clamp on neighboring ones Formwork elements are made. Even if the straightening clamp (1) is installed in the position shown in FIG. 1, which should normally be the case, the claw (4) does not unintentionally snap out of the set position, in particular if the claw has already been attached to the frame of a formwork panel is.

Claims (5)
