Abstract

A frame (3) of a form panel (1) is formed by a hollow profile (4), preferably having a closed cross-section, the cross-section of this hollow profile (4) corresponding substantially approximately to a rectangle. Provided adjacent to the outermost edge web (5) of this hollow profile (4) but without affecting the length or width of this edge web (5), on a profile section or end web (9) running transversely to this edge web (5), is at least one recess (7), to which a crowbar (8) can be attached when the edge web (5) is standing on a ground surface (6) or the like. The edge web (5) can thus have its greatest possible width on the hollow profile (4) despite such a recess (7) serving for the engagement of a crowbar (8) and is protected in the best possible way against deformations by the crowbar (8), so that it remains a substantially level and undeformed stop for a neighbouring shuttering element even after prolonged use. <IMAGE>

Description

Die Erfindung betrifft einen Rahmen für Schaltafel gemäß dem Oberbegriff des Patentanspruches 1.
Ein derartiger Rahmen ist aus der DE-A 34 29 304 bekannt. Die Vertiefung zum Angriff eines Brecheisens ist dabei in demjenigen Eckbereich des Hohlprofiles angeordnet, der durch die äußeren Seitenflächen und die der Schalhaut abgewandte Fläche, also einen von der Schalhaut abliegenden Abschlußsteg und den Randsteg gebildet wird. Ist eine solche Schaltafel mit einem Rahmenschenkel auf einer Standfläche aufgestellt, kann sie durch ein an der Vertiefung angesetztes Brecheisen etwas angehoben und versetzt oder ausgerichtet werden.The invention relates to a frame for formwork panel according to the preamble of claim 1.
Such a frame is known from DE-A 34 29 304. The depression for attacking a crowbar is arranged in that corner region of the hollow profile which is formed by the outer side surfaces and the surface facing away from the formlining, that is to say an end web remote from the formwork facing and the edge web. If such a formwork panel with a frame leg is set up on a standing surface, it can be lifted and offset or aligned somewhat using a crowbar attached to the recess.

Hohlprofile werden vor allem dann als Rahmen bei Schaltafeln angewendet, wenn diese ein hohes Gewicht haben. Wird nun an der erwähnten, in einer äußeren Ecke des Hohlprofiles befindlichen Vertiefung ein Brecheisen angesetzt, werden die davon ausgehenden Kräfte auch zu einem erheblichen Teil in den als Anschlag und Abdichtung mit einer Nachbar-Schaltafel dienenden Randsteg eingeleitet, was zu dessen Verformung führen kann, so daß sich Unebenheiten und dergleichen bilden können und die Dichtigkeit beim Zusammenfügen solcher Schaltafeln zumindest nach mehrmaligem Ausrichten und Versetzen mit Hilfe eines Brecheisens noch weniger gewährleistet ist.Hollow sections are mainly used as frames for formwork panels when they are heavy. If a crowbar is now attached to the recess mentioned in an outer corner of the hollow profile, the resulting forces are also introduced to a considerable extent into the edge web serving as a stop and seal with a neighboring formwork panel, which can lead to its deformation, so that bumps and the like can form and the tightness when assembling such formwork panels at least after repeated alignment and Moving with the help of a crowbar is even less guaranteed.

Es besteht deshalb die Aufgabe, einen Rahmen für Schaltafeln der im Oberbegriff des Patentanspruches 1 erwähnten Gattung herzustellen, der ein Anheben der Schaltafel mit einem Brecheisen ermöglicht, ohne daß der Randsteg beschädigt wird.It is therefore the task of producing a frame for formwork panels of the type mentioned in the preamble of claim 1, which enables the formwork panel to be lifted with a crowbar without the edge web being damaged.

Diese Aufgabe wird mit den Merkmalen und Maßnahmen des Patentanspruches 1 gelöst.This object is achieved with the features and measures of claim 1.

Durch diese Lösung können die Reaktionskräfte des Brecheisens von dem Randsteg ferngehalten werden, weil die Vertiefung nicht mehr im Eckbereich, sondern lediglich im Abschlußsteg angebracht wird, so daß der Randsteg von der Vertiefung unbehelligt bleibt. Statt also einen vertieften und ausgenommenen Eckbereich des Hohlprofiles für den Ansatz eines Stemmeisens vorzusehen, bleiben die Eckbereiche des Hohlprofiles gemäß der Erfindung erhalten und die Vertiefung ist zwischen diesen Eckbereichen und jeweils oberhalb dem Eckbereich an dem der Schalhaut abgewandten Rand des Randsteges angeordnet. Somit kann dieser Randsteg seine volle Breite und Form behalten, ohne daß etwa die Breite des gesamten Hohlprofiles zur Berücksichtigung einer Vertiefung vergrößert werden müßte.With this solution, the reaction forces of the crowbar can be kept away from the edge web, because the depression is no longer made in the corner area, but only in the end web, so that the edge web remains undisturbed by the depression. Instead of providing a recessed and recessed corner area of the hollow profile for the attachment of a chisel, the corner areas of the hollow profile are preserved according to the invention and the recess is arranged between these corner areas and above the corner area on the edge of the edge web facing away from the formlining. This edge web can thus retain its full width and shape without the width of the entire hollow profile having to be increased to take into account a depression.

Somit ist ein nahezu kastenförmiges Hohlprofil möglich, welches auch an seinem der Schalhaut abgewandten Rand Ecken oder dergleichen Formgebungen zur Vergrößerung der Steifigkeit aufweist, zwischen denen die Vertiefung oder Vertiefungen angeordnet sein können, so daß die an diesen ansetzenden Reaktionskräfte vor allem in den in Gebrauchsstellung oberhalb der Vertiefung befindlichen Stegabschnitt und außerdem den darüberliegenden Haltesteg eingeleitet werden können. Vor allem bei einer geringfügigen elastischen Nachgiebigkeit dieser Steganordnungen bleibt der eigentliche Randsteg von den Reaktionskräften praktisch unbehelligt und erfährt vor allem keine bleibenden Verformungen. Somit ist auch nach mehrmaligem Ansetzen eines Brech- oder Stemmeisens nach wie vor eine gute Anlage an dem Randsteg und eine gute Dichtigkeit mit einem Nachbar-Randsteg gegeben.This makes an almost box-shaped hollow profile possible, which also has corners or similar shapes on its edge facing away from the formlining to increase the rigidity, between which the recess or recesses can be arranged, so that the reaction forces applied to them, especially in the position of use above the recess located web section and also the overlying holding web can be initiated. Especially with a slight elastic compliance In these web arrangements, the actual edge web remains practically unaffected by the reaction forces and, above all, does not experience any permanent deformations. Thus, even after repeated application of a crowbar or crowbar, there is still good contact with the edge web and good tightness with a neighboring edge web.

Ausgestaltungen des Rahmens bezüglich des Haltesteges und der Vertiefung sind Gegenstand der Ansprüche 2 und 3.Embodiments of the frame with respect to the holding web and the recess are the subject of claims 2 and 3.

Die Vertiefung oder Vertiefungen können durch ein an einer Öffnung des Abschlußsteges angeordnetes, in das Innere des Hohlprofiles ragendes, nach außen offenes Vertiefungsprofil begrenzt und ausgesteift sein und das Vertiefungsprofil kann einen U-förmigen, rechteckigen, trapezförmigen, gerundeten oder V-förmigen Querschnitt haben. Somit findet ein Brech- oder Stemmeisen gewissermaßen eine taschenförmige Vertiefung zwischen den bei seinem Ansetzen jeweils etwa horizontal liegenden, rechtwinklig von der Schalhaut abgehenden Stegen des Hohlprofiles. Entsprechend gut können die von diesem Brecheisen ausgehenden Kräfte aufgefangen werden.The depression or depressions can be limited and stiffened by a depression profile which is arranged at an opening of the end web and projects into the interior of the hollow profile and which is open to the outside, and the depression profile can have a U-shaped, rectangular, trapezoidal, rounded or V-shaped cross section. Thus, a crowbar or chisel finds, as it were, a pocket-shaped recess between the webs of the hollow profile that are approximately horizontal each time it is attached and that depart perpendicularly from the formlining. The forces emanating from this crowbar can be absorbed accordingly.

Dabei kann das Vertiefungsprofil einstückig mit den Stegabschnitten und vorzugsweise auch den Stegen des Hohlprofiles verbunden oder nachträglich damit verschweißt sein.The recess profile can be made in one piece with the web sections and preferably also connected to the webs of the hollow profile or subsequently welded to it.

An dem Abschlußsteg können mehrere mit Abstand zueinander angeordnete, jeweils eine begrenzte Länge aufweisende Vertiefungen oder auch ein über die gesamte Länge des jeweiligen Rahmenschenkels verlaufende Vertiefung vorgesehen sein. Im ersteren Falle ergibt sich eine größere Steifigkeit, im letzteren Falle ist eine einfachere Herstellung möglich.A plurality of wells arranged at a distance from one another, each having a limited length, or else a well extending over the entire length of the respective frame leg can be provided on the end web. In the former case there is greater rigidity, in the latter case simpler manufacture is possible.

Ausgestaltungen des Rahmens, des Hohlprofiles und insbesondere des Vertiefungsprofiles sowie der Vertiefung sind Gegenstand der Ansprüche 7 bis 13. Daraus ergibt sich eine Vielzahl von Möglichkeiten, die Vertiefungen und die sie bildenden Stege so zu gestalten, daß einerseits das den Rahmen bildende Hohlprofil stabil und steif ist und andererseits ein guter Angriff für ein Brecheisen gewährleistet ist, ohne daß der Randsteg zu diesem Zweck verkürzt sein muß und zu starken Kräften ausgesetzt wird, die ihn im Laufe der Zeit dauerhaft verformen könnten. Dabei sei erwähnt, daß der geringfügige Abstand, der sich zwischen einem auf dem Boden oder einer Standfläche aufsitzenden Randsteg und dem von einem Stemmeisen zu beaufschlagenden Widerlagerbereich in der Vertiefung vorhanden ist, durch die Wahl eines entsprechend geformten Stemm- oder Brecheisens oder aber ein neben dem Randsteg unter das Brecheisen zu legenden Abstandhalter überbrückt werden kann.Embodiments of the frame, the hollow profile and in particular the recess profile and the recess are the subject of claims 7 to 13. This results in a multitude of possibilities for designing the recesses and the webs forming them so that on the one hand the hollow profile forming the frame is stable and rigid is and on the other hand a good attack for a crowbar is guaranteed, without the edge web must be shortened for this purpose and exposed to strong forces that could deform it over time. It should be mentioned that the slight distance that exists between an edge web sitting on the floor or a standing surface and the abutment area to be acted upon by a chisel, by the choice of an appropriately shaped chisel or crowbar or one next to that Edge web can be bridged under the spacer to be placed under the crowbar.

Vor allem die Maßnahmen der Ansprüche 8 und 9 verbessern die Einleitung der von einem Stemmeisen ausgehenden Kräfte in den Abschluß- und Haltesteg. Vor allem Sicken und dergleichen im Bereich der Vertiefungen können dabei zu einer Aussteifung beitragen, die den von einem Brecheisen ausgehenden Kräften entsprechend besser widerstehen kann.In particular, the measures of claims 8 and 9 improve the introduction of the forces emanating from a chisel into the end and retaining web. In particular, beads and the like in the area of the depressions can contribute to stiffening, which can better withstand the forces exerted by a crowbar.

Statt des Vertiefungsprofiles, womit also die Vertiefung bis auf ihre nach außen verlaufende, für das Einführen des Brecheisens dienende Öffnung umkleidet ist, ist auch eine Lösung möglich, bei der die Vertiefungen an dem Abschlußsteg durch diesen Steg durchsetzende, in das Innere des Hohlprofiles durchgehende Öffnungen gebildet sind, bei denen gegebenenfalls wenigstens der dem Halteprofil zugewandte Rand, vorzugsweise der gesamte Umfang oder alle Ränder verstärkt sind. Durch die fehlende innere Auskleidung der Vertiefung wird auf diese Weise der Rahmen leichter und preiswerter.Instead of the recess profile, with which the recess is covered except for its outwardly extending opening, which is used for the insertion of the crowbar, a solution is also possible in which the recesses on the end web penetrate through this web and pass through openings into the interior of the hollow profile are formed, in which at least the edge facing the holding profile, preferably the entire circumference or all edges, are reinforced. The missing inner lining of the recess makes the frame lighter and cheaper in this way.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen ergibt sich ein Rahmen für Schaltafeln, an dem problemlos und unter Schonung des eigentlichen Randsteges ein Stemmeisen beim Ausrichten der Schaltafel angesetzt werden kann, wobei außerdem in vorteilhafter Weise der Randsteg seine größtmögliche Breite in Relation zu der Gesamtabmessung des Hohlprofiles behalten kann. Da die von dem Stemmeisen ausgehenden Reaktionskräfte vor allem in den parallel zu dem Randsteg befindlichen Haltesteg eingeleitet werden, ist vor allem auch die Gefahr einer bleibenden Verformung des Randsteges, der für die Dichtigkeit der gesamten Schalung sehr wichtig ist, praktisch ausgeschlossen.Especially when combining one or more of the features and measures described above, there is a frame for formwork panels, on which a chisel can be attached easily and while protecting the actual edge web when aligning the formwork panel, the edge web also advantageously being its greatest possible width in relation can keep to the overall dimension of the hollow profile. Since the reaction forces emanating from the chisel are primarily introduced into the holding web located parallel to the edge web, the risk of permanent deformation of the edge web, which is very important for the tightness of the entire formwork, is practically excluded.

Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten anhand der Zeichnung noch näher beschrieben.The invention is described in more detail below with its details that are essential to it, using the drawing.

Die einzige Figur zeigt in schematisierter Darstellung
   einen Querschnitt durch einen auf dem Boden aufsitzenden Rahmenschenkel eines Rahmens einer Schaltafel, wobei das Hohlprofil in seinem der Schalhaut abgewandten Bereich oberhalb des Randsteges eine diesem gegenüber zurückspringende Vertiefung zum Ansetzen eines Stemmeisens hat, der Randsteg aber seine der größten Abmessung des Hohlprofiles quer zur Schalhaut entsprechende Breite aufweist.The only figure shows a schematic representation
a cross section through a frame leg of a frame of a formwork panel sitting on the floor, the hollow profile above the edge web in its area facing away from the formwork skin this has a recess that recesses to attach a chisel, but the edge web has its width corresponding to the largest dimension of the hollow profile transverse to the formlining.

Eine im ganzen mit 1 bezeichnete, mit ihrem unteren Randbereich im Querschnitt dargestellte Schaltafel hat an den Rändern ihrer Schalhaut 2 einen im ganzen mit 3 bezeichneten Rahmen, dessen einzelne Rahmenschenkel durch ein einen geschlossenen Querschnitt aufweisendes Hohlprofil 4 gebildet ist. Der äußerste, etwa rechtwinklig zur Schalhaut 2 verlaufende Randsteg 5 dieses Hohlprofiles 4 bildet dabei jeweils einen Anschlag für den Rahmen 3 oder Anschlag einer Nachbar-Schaltafel oder eines sonstigen anzuschließenden Schalungselementes wie zum Beispiel einer Schalungsecke oder dergleichen, soll also möglichst eben und mit geradlinigem Querschnitt versehen sein und für eine gute Dichtigkeit und Anlage auch eine möglichst große Querschnittslänge haben.A formwork panel, generally designated 1, with its lower edge region shown in cross section, has on the edges of its formwork skin 2 a framework, generally designated 3, the individual frame legs of which are formed by a hollow cross section 4 having a closed cross section. The outermost edge web 5 of this hollow profile 4, which runs approximately at right angles to the formlining 2, in each case forms a stop for the frame 3 or stop for a neighboring formwork panel or other formwork element to be connected, such as a formwork corner or the like, so it should be as flat as possible and with a linear cross section be provided and also have the largest possible cross-sectional length for good tightness and fit.

Im Ausführungsbeispiel ist ein Rahmenschenkel mit diesem Randsteg 5 auf einen Boden oder eine sonstige Standfläche 6 aufgesetzt, um eine Schalung zu bilden. Damit die Schaltafel 1 eventuell in dieser Position zum Ausrichten geringfügig versetzt werden kann, weist das Hohlprofil 4 in seinem der Schalhaut 2 abgewandten Bereich wenigstens eine in seinen Querschnitt ragende Vertiefung 7 für den Angriff eines Brecheisens 8 auf.In the exemplary embodiment, a frame leg with this edge web 5 is placed on a floor or other standing surface 6 in order to form a formwork. So that the formwork panel 1 can possibly be displaced slightly in this position for alignment, the hollow profile 4 has in its area facing away from the formwork skin 2 at least one recess 7 projecting in its cross section for the attack of a crowbar 8.

Dabei ist in der Zeichnung deutlich dargestellt, daß diese Vertiefung 7 benachbart zu dem äußersten Randsteg 5 in einem quer zu diesem Randsteg 5 verlaufenden Abschlußsteg 9 vorgesehen ist und gegenüber dem der Schalhaut 2 abgewandten Rand oder Ende 5a des Randsteges 5 in das Innere des Hohlprofiles 4 gerichtet ist und zurückspringt.It is clearly shown in the drawing that this recess 7 is provided adjacent to the outermost edge web 5 in a terminating web 9 running transversely to this edge web 5 and opposite the edge or end 5a of the edge web 5 facing away from the formlining 2 into the interior of the hollow profile 4 is directed and jumps back.

Somit kann das Brecheisen 8 an einem in dieser Gebrauchsstellung oberen Begrenzungs-Steg 10 der Vertiefung 7 angreifen, d.h. der Randsteg 5 und sein Rand 5a bleiben von dem Arbeitsende des Brecheisens 8 unbehelligt. Somit wird die Gefahr einer Verformung des Randsteges 5 vermieden und der Randsteg 5 kann seine größtmögliche Ausdehnung entsprechend der Querschnittsbreite des Hohlprofiles 4 haben.Thus, the crowbar 8 can engage an upper boundary web 10 of the recess 7 in this position of use, i.e. the edge web 5 and its edge 5a remain undisturbed by the working end of the crowbar 8. The risk of deformation of the edge web 5 is thus avoided and the edge web 5 can have its greatest possible extent in accordance with the cross-sectional width of the hollow profile 4.

An dem Hohlprofil 4 sind der Randsteg 5 und ein mit Abstand dazu angeordneter, im Ausführungsbeispiel paralleler Haltesteg 11 vorgesehen und die Vertiefung 7 ist an oder in dem quer, im Ausführungsbeispiel rechtwinklig zu diesen Stegen 5 und 11 verlaufenden Abschlußsteg 9 des Hohlprofiles 4 angeordnet beziehungsweise eingearbeitet. Der Abschlußsteg 9 weist dabei an den sich gegenüberliegenden, der Schalhaut 2 fernen Enden oder Rändern 5a beziehungsweise 11 a des Randsteges 5 und des Haltesteges 11 jeweils Ecken bildende Stegabschnitte 9a auf,deren einander zugewandten Ränder 9b die Vertiefung 7 begrenzen.On the hollow profile 4, the edge web 5 and a spaced-apart, in the exemplary embodiment parallel holding web 11 are provided and the recess 7 is arranged or incorporated on or in the transverse web, in the exemplary embodiment running at right angles to these webs 5 and 11, of the hollow profile 4 . The end web 9 has, at the opposite ends or edges 5a or 11a of the edge web 5 and the holding web 11, each of which forms corner sections, the mutually facing edges 9b of which delimit the recess 7 at the opposite ends or edges 5a or 11a of the edge web 5.

Im Ausführungsbeispiel ist die Vertiefung 7 durch ein an einer öffnung des Abschlußsteges 9 angeordnetes, in das Innere des Hohlprofiles 4 ragendes, nach außen offenes Vertiefungsprofil 12 begrenzt und ausgesteift. Dabei hat dieses Vertiefungsprofil 12 einen U-förmigen und rechteckigen Querschnitt. Es könnte jedoch auch trapezförmig, gerundet oder V-förmig gestaltet sein.In the exemplary embodiment, the depression 7 is delimited and stiffened by an outwardly open depression profile 12 which is arranged at an opening of the end web 9 and projects into the interior of the hollow profile 4. This recess profile 12 has a U-shaped and rectangular cross section. However, it could also be trapezoidal, rounded or V-shaped.

In zweckmäßiger Weise für eine gute Kraftübertragung ist im Ausführungsbeispiel das Vertiefungsprofil 12 einstückig mit den Stegabschnitten 9a des Abschlußsteges 9 und somit auch den übrigen Stegen des Hohlprofiles 4 verbunden. Es könnte aber auch nachträglich damit verschweißt sein.In an advantageous manner for good power transmission, in the exemplary embodiment the depression profile 12 is connected in one piece to the web sections 9a of the end web 9 and thus also the other webs of the hollow profile 4. But it could also be welded to it later.

Im Ausführungsbeispiel ist an dem Rahmen 3 eine über die gesamte Länge des jeweiligen Rahmenschenkels verlaufende Vertiefung 7 vorgesehen. Dabei läßt sich die Ausbildung mit Hilfe eines Vertiefungsprofiles 12 am besten realisieren. Es ist jedoch auch möglich, an dem Abschlußsteg 9 mehrere mit Abstand zueinander angeordnete, jeweils eine begrenzte Länge aufweisende Vertiefungen 7 vorzusehen. Falls diese dabei ebenfalls mit einem Vertiefungsprofil 12 ausgekleidet sein sollen, ist dieses einzuschweißen und mit stirnseitigen Abschlüssen zu versehen oder durch Tiefziehen einzuformen.In the exemplary embodiment, one is on the frame 3 Entire length of the respective frame leg extending recess 7 is provided. The training can best be realized with the help of a deepening profile 12. However, it is also possible to provide a plurality of depressions 7 which are arranged at a distance from one another and each have a limited length. If these are also to be lined with a recess profile 12, this is to be welded in and provided with end closures or molded in by deep drawing.

Der dem Haltesteg 11 zugewandte Bereich des Vertiefungsprofiles 12 ist seinerseits als Steg 10 ausgebildet, der mit Abstand zu dem Haltesteg 11, im Ausführungsbeispiel parallel dazu, verläuft. Der lichte Abstand zwischen dem Haltesteg 11 und diesem Steg 10 des Vertiefungsprofiles 12 kann dabei gleich oder größer als die Querschnittsdicke der Stege sein, beispielsweise etwa der doppelten Dicke der Stege entsprechen. Somit ergibt sich am Rand 11a des Haltesteges 11 eine U-förmige Querschnittsform, die dem Angriff des Brecheisens 8 einen erwünscht hohen Widerstand entgegensetzt und eine hohe Steifigkeit hat, um die dabei auftretenden Kräfte ohne Verformungsgefahr vor allem für den Randsteg 5 aufnehmen zu können.The area of the depression profile 12 facing the holding web 11 is in turn designed as a web 10 which runs at a distance from the holding web 11, in the exemplary embodiment parallel to it. The clear distance between the holding web 11 and this web 10 of the recess profile 12 can be equal to or greater than the cross-sectional thickness of the webs, for example correspond to approximately twice the thickness of the webs. This results in a U-shaped cross-sectional shape at the edge 11a of the holding web 11, which opposes the attack of the crowbar 8 with a desired high resistance and has a high degree of rigidity in order to be able to absorb the forces occurring without any risk of deformation, especially for the edge web 5.

Da die Vertiefung 7 im Ausführungsbeispiel mittig und symmetrisch zwischen dem Haltesteg 11 und dem Randsteg 5 angeordnet ist, ergibt sich eine analoge etwa nut- oder U-förmige Querschnittsform auch am Rand 5a des Randsteges 5, so daß auch hier die Steifigkeit erhöht und somit die Gefahr einer Verformung weiter vermindert ist.Since the recess 7 in the exemplary embodiment is arranged centrally and symmetrically between the holding web 11 and the edge web 5, there is an analog approximately groove-shaped or U-shaped cross-sectional shape also at the edge 5a of the edge web 5, so that here too the rigidity and thus the Danger of deformation is further reduced.

Die Steifigkeit dieser Randbereiche 5a und 11a hängt auch etwas davon ab, wie lang der Steg 10 des Vertiefungsprofiles 12 ist. Je größer die Länge ist, umso eher können wiederum Verformungen vor allem an dem Vertiefungsprofil 12 auftreten. Im Ausführungsbeispiel ist deshalb die Tiefe der Vertiefung 7 gegenüber dem Abschlußsteg 9 und den der Schalhaut 2 abgewandten Rändern 5a und 11a etwa halb so groß oder sogar noch etwas kleiner als der Abstand zwischen Haltesteg 11 und Randsteg 5. Im Ausführungsbeispiel entspricht diese Tiefe der Vertiefung 7 etwa einem Drittel des Abstandes zwischen Haltesteg 11 und Randsteg 5.The rigidity of these edge regions 5a and 11a also depends somewhat on how long the web 10 of the recess profile 12 is. The greater the length, the sooner you can in turn, deformations occur primarily on the recess profile 12. In the exemplary embodiment, the depth of the recess 7 is therefore approximately half as large or even slightly smaller than the distance between the retaining web 11 and the edge web 5 compared to the end web 9 and the edges 5a and 11a facing away from the formlining 2. In the exemplary embodiment, this depth corresponds to the recess 7 about a third of the distance between the retaining web 11 and the edge web 5.

Gegebenenfalls könnte der lichte Abstand zwischen dem Haltesteg 11 und dem diesem benachbarten Steg 10 des Vertiefungsprofiles 12 wenigstens bereichsweise ausgefüllt sein. Beispielsweise könnten Versteifungsstege oder aber sickenförmige Einformungen an einem oder beiden Stegen 10 und 11 vorgesehen sein. Auch noppenförmige Verformungen könnten eine gegenseitige Abstützung der Stege 10 und 11 und somit eine Aussteifung des von dem Brecheisen 8 beaufschlagten Randbereiches 11a bewirken.If necessary, the clear distance between the retaining web 11 and the adjacent web 10 of the recess profile 12 could be at least partially filled. For example, stiffening webs or bead-shaped indentations could be provided on one or both webs 10 and 11. Also knob-shaped deformations could cause mutual support of the webs 10 and 11 and thus a stiffening of the edge area 11a acted upon by the crowbar 8.

Im Ausführungsbeispiel ist die Querschnittslänge des Randsteges 5 ausgehend von der Rückseite der Schalhaut 2, also ohne den über die Schmalseite der Schalhaut 2 reichenden Abschnitt, gleich der des Haltesteges 11. Die beiden an den Rändern oder Enden 5a beziehungsweise 11a dieser Stege 5 und 11 befindlichen Eckbereiche des Hohlprofiles 4 sind somit im gleichen Abstand von der Schalhaut 2 angeordnet. Es wäre aber sogar aufgrund der unabhängig von dem Randsteg 5 angeordneten Vertiefung 7 möglich, daß diese Querschnittslänge des Randsteges 5 sogar größer als die des Haltesteges 11 gemacht wird und dann auch der mit dem Randsteg 5 gebildete Eckbereich einen größeren Abstand zur Schalhaut 2 als der Eckbereich an dem Haltesteg hat. Der Randsteg 5 kann also in jedem Falle mit einer derartigen Breite beziehungsweise Querschnittslänge ausgerüstet werden, wie es für einen dichten und genauen Anschlag gegenüber einer Nachbar-Schaltafel oder einem sonstigen anzuschließenden Schalungselement wünschenswert ist. Trotzdem ist ein Ausrichten einer solchen Schaltafel 1, die auf einem Boden 6 mit einem Randsteg 5 aufsteht, mit Hilfe des Stemmeisens 8 problemlos möglich, wobei ein Angriff dieses Stemmeisens 8 an dem Randsteg 5 aufgrund der dann in Gebrauchsstellung höherliegenden Vertiefung 7 vermieden wird.In the exemplary embodiment, the cross-sectional length of the edge web 5, starting from the rear of the formwork skin 2, that is to say without the section extending over the narrow side of the formwork skin 2, is equal to that of the holding web 11. The two located at the edges or ends 5a and 11a of these webs 5 and 11 Corner areas of the hollow profile 4 are thus arranged at the same distance from the formlining 2. However, it would even be possible, owing to the recess 7 arranged independently of the edge web 5, that this cross-sectional length of the edge web 5 is even made larger than that of the holding web 11 and then also the corner region formed with the edge web 5 a greater distance from the formwork skin 2 than the corner region on the landing stage. The edge web 5 can in any case be equipped with such a width or cross-sectional length as is necessary for a tight and precise stop compared to a neighboring formwork panel or another formwork element to be connected. Nevertheless, alignment of such a formwork panel 1, which stands on a floor 6 with an edge web 5, is easily possible with the chisel 8, an attack of this chisel 8 on the edge web 5 being avoided due to the recess 7 which is then higher in the use position.

Es sei noch erwähnt, daß wenigstens einer der Eckbereiche, also der Übergang von dem Haltesteg 11 zu dem Abschlußsteg 9 und/oder der Übergang von dem Randsteg 5 zu dem Abschlußsteg 9 abgeschrägt oder abgerundet sein kann, falls dies aus Stabilitätsgründen oder sonstigen Gründen wie zum Beispiel der Anbringung entsprechender Klammern beim Verbinden von Rahmen 3 benachbarter Schaltafeln oder dergleichen erforderlich wäre.It should also be mentioned that at least one of the corner areas, i.e. the transition from the retaining web 11 to the end web 9 and / or the transition from the edge web 5 to the end web 9, can be chamfered or rounded off if this is for reasons of stability or other reasons such as Example of attaching appropriate brackets when connecting frame 3 adjacent formwork panels or the like would be required.

Ferner kann ein insgesamt gerundeter übergang von dem Haltesteg 11 und/oder dem Randsteg 5 in das Vertiefungsprofil 12 vorgesehen sein, d.h. der Abschlußsteg 9 oder seine Abschnitte 9a können bogenförmig gestaltet sein.Furthermore, an overall rounded transition from the retaining web 11 and / or the edge web 5 into the recess profile 12 can be provided, i.e. the end web 9 or its sections 9a can be designed in an arc shape.

Schließlich wäre eine weitere Ausgestaltung oder Abwandlung dahingehend möglich, daß das Vertiefungsprofil 12 fehlt und die Vertiefungen 7 an dem Abschlußsteg 9 durch diesen Steg durchsetzende, in das Innere des Hohlprofiles 4 durchgehende beziehungsweise offene Öffnungen gebildet sind, bei denen gegebenenfalls wenigstens der dem Haltesteg 11 zugewandte Rand 9b, vorzugsweise aber der gesamte Umfang oder alle Ränder verstärkt sein könnten, beispielsweise durch aufgeschweißte zusätzliche Stege. Auch nach innen eingeklinkte Verstärkungsstege könnten eine solche nach innen offene Vertiefung 7 begrenzen und aussteifen.Finally, a further embodiment or modification would be possible in that the recess profile 12 is missing and the recesses 7 on the end web 9 are formed by openings which pass through this web and which are continuous or open in the interior of the hollow profile 4, in which openings at least the one facing the holding web 11 is formed Edge 9b, but preferably the entire circumference or all edges could be reinforced, for example by additional webs welded on. Reinforcement webs clipped inwards could also limit and stiffen such an inward opening 7.

Der Rahmen 3 einer Schaltafel 1 ist durch ein bevorzugt einen geschlossenen Querschnitt aufweisendes Hohlprofil 4 gebildet, wobei der Querschnitt dieses Hohlprofiles 4 im wesentlichen etwa einem Rechteck entspricht. Benachbart zu dem äußersten Randsteg 5 dieses Hohlprofiles 4, aber ohne Beeinträchtigung der Länge oder Breite dieses Randsteges 5 ist an einem quer zu diesem Randsteg 5 verlaufenden Profilabschnitt oder Abschlußsteg 9 wenigstens eine Vertiefung 7 vorgesehen, an der ein Stemmeisen 8 ansetzen kann, wenn der Randsteg 5 auf einer Bodenfläche 6 oder dergleichen aufsteht. Der Randsteg 5 kann also trotz einer solchen für den Angriff eines Stemmeisens 8 dienenden Vertiefung 7 an dem Hohlprofil 4 seine größtmögliche Breite haben und ist vor Verformungen durch das Stemmeisen 8 bestmöglich geschützt, so daß er auch nach längerem Gebrauch als im wesentlichen ebener und unverformter Anschlag für ein Nachbar-Schalungselement erhalten bleibt.The frame 3 of a formwork panel 1 is preferred by one formed a closed cross-section hollow profile 4, the cross section of this hollow profile 4 corresponds approximately to a rectangle. Adjacent to the outermost edge web 5 of this hollow profile 4, but without impairing the length or width of this edge web 5, at least one recess 7 is provided on a profile section or end web 9 extending transversely to this edge web 5, to which a chisel 8 can attach when the edge web 5 stands on a floor surface 6 or the like. The edge web 5 can thus have its greatest possible width in spite of such a depression 7 serving for the attack of a chisel 8 on the hollow profile 4 and is optimally protected from deformations by the chisel 8, so that it remains as a substantially flat and undeformed stop even after prolonged use for a neighboring formwork element is retained.
