  • the cross sections of the two support sections to take the mounting flanges into account differ considerably from one another in that the angle enclosed by the U-legs is more acute in the internal support section than in the support section surrounding it, so that the mounting flanges of both Carrier sections each have different distances and the outer carrier section can accommodate the inner carrier section together with its protruding flanges. Nevertheless, it is ensured that the inner support section - seen in cross section - also obliquely diverging legs has, which can be moved with its mounting flanges without permanent deformation when the curvature of the formwork panel is changed. At the same time, a correspondingly good stiffening also results in the extension area. Such an extension can take place both vertically and vertically with the carrier arranged vertically.
  • the U-crossbars of the two partially interlocking support sections can lie against one another in the position of use and can be releasably connected to one another.

  • the fastening element has a thread on the outside of the carrier and a nut which can be tightened thereon.
  • a screw with almost any head can serve as a fastening element, the head of which, under the inside as a counter-guiding element, engages underneath the edges of the longitudinal slot of the inner carrier section, while on the outside a conventional threaded nut in the loosened state enables mutual displacement during length adjustment and in the tightened state the carrier parts against each other.
  • this head can have corresponding flat sides and come to rest in a recess in such a way that its rotation is prevented.
  • the inner support part can be composed of two approximately Z-shaped support profiles which have a slot spacing from one another in the region of the U crossbar and which are held together by cross connectors or cross plates located in the interior of the U cross section. In this way, there is a continuous guide slot over the entire length of the inner carrier part.
  • the Z-shaped support profiles after their mutual connection by means of transverse plates as a whole have great rigidity that the forces occurring in the extension area of such switchboards can be absorbed with corresponding certainty. Subsequent milling of a guide slot can be avoided.

  • the U-legs of the carrier parts can thus be moved laterally without permanent deformation and the formwork can be curved or its curvature can be bent about one or more axes running parallel to the carrier or carriers.
  • the side wall can be easily formed with the required curvatures corresponding to the curve's bend, while the slope of the lane is also taken into account by correspondingly different extensions of the formwork panel supports can.

  • such cross connectors can either be provided at its ends or a cross connector can also be arranged in the middle to improve the mutual stiffening of the Z-shaped support profiles.
  • the manufacture of this support section serving as an extension is correspondingly simple.
  • the extension parts advantageously have a trapezoidal, that is to say insofar, corresponding geometric shape as the carrier sections or trapezoidal carriers present on the formwork panel, but are dimensionally modified with respect to their cross-section such that they are in particular continuously displaceable relative to these carrier parts, although flanges projecting outwards are provided on their U-legs for connection to the formlining.

Abstract

A lining board (1) has a lining skin (2) and a support (4) that supports the skin at the side opposite to the concrete and if required marginal bars (3) that extend in an approximately parallel direction to the supports (4). Adjacent lining boards (1) may be coupled and joined to each other. The supports (4) have an approximately U-shaped cross section. The legs (5) of the U extend away from each other on a U cross-bar (6) and their free ends, where their mutual distance is the largest, are provided with diverging fastening flanges (7) for joining them to the lining skin (2). In order to extend the lining board at least on one side in the same direction as the longitudinal extension of the support (4), each support (4) consists of two parts or sections (4a and 4b) adjustable in relation to each other in the longitudinal direction and which overlap at least in one overlapping area. The angle of inclination formed by the legs of the inner support section (4b) and the lining skin (2) at the inner side of its cross section is blunter or larger than the corresponding angle of the overlapping support section (4a), or the angle between both legs of the inner support section (4b) is sharper than the corresponding angle between the legs (5) of the outer support section (4a). The angles are selected so that when the cross-bars (6) of the U lie next to each other the clearance between the U-legs (5) of the inner support section (4b) at the lining skin (2) is smaller than the clearance at the outer support section (4a) in the same spot by approximately the total width of the diverging fastening flanges (7), so that the fastening flanges (7) of both support sections lie next to each other in the same plane when the lining skin (2) is even.

Description

Schaltafel mit Träger mit etwa U-förmigem Querschnitt Formwork panel with carrier with an approximately U-shaped cross-section
Die Erfindung betrifft eine Schaltafel mit wenigstens einem die Schalhaut auf der dem Beton abgewandten Seite abstützendem Träger, der einen etwa U-förmigen Querschnitt aufweist, dessen U-Schenkel durch einen U-Quersteg verbunden sind, welcher sich auf der von der Schalhaut abgewandten Seite befindet, und dessen U-Schenkel im Querschnitt gesehen von dem U-Quersteg aus schräg auseinanderlaufen und an ihren freien Enden jeweils - im Querschnitt gesehen - von den U- Schenkeln nach außen abstehende und voneinander weggerichtete Befestigungsflansche zum Angreifen an der Schalhaut haben.The invention relates to a formwork panel with at least one support supporting the formlining on the side facing away from the concrete, which has an approximately U-shaped cross section, the U-legs of which are connected by a U-transverse web, which is located on the side facing away from the formwork facing , and the U-legs seen in cross-section from the U-cross bar diverge diagonally and at their free ends - seen in cross-section - from the U-legs projecting outward and away from each other fastening flanges for engaging the formwork skin.
Eine derartige Schaltafel ist zum Beispiel aus der DE-PS 24 26 708 bekannt. Die darin beschriebenen Schaltafeln sind Teile von Großflächenschalungen für verschieden gekrümmte Flächen mit einer bezüglich Ihrer Krümmung einstellbaren Schalhaut. Dazu trägt bei, daß die U-Schenkel bei der Veränderung der Krümmung jeweils ohne bleibende Verformung seitlich bewegbar sind und an den U-Querstegen Gurtabschnitte mit veränderbarer Länge angreifen. Diese Schalung hat sich bewährt.Such a panel is known for example from DE-PS 24 26 708. The formwork panels described therein are parts of large-area formwork for differently curved surfaces with a formwork skin that can be adjusted with regard to their curvature. This contributes to the fact that the U-legs can be moved laterally when the curvature changes without permanent deformation and engage belt sections of variable length on the U-crossbars. This formwork has proven itself.
Falls es erforderlich ist, oberhalb oder unterhalb einer solchen Schalung über deren Höhenabmessung hinausgehende Schalarbeiten durchzuführen, ist jedoch bisher eine entspre¬ chende Aufstockung oder Verlängerung nach unten schwierig. Dies gilt vor allem beispielsweise beim Schalen der Seitenwand einer schrägen Rampe oder Auffahrt, die geradeaus oder gleichzeitig gekrümmt verlaufen kann.If it is necessary to perform formwork work above or below such formwork above or below such formwork, it has so far been difficult to increase or extend the formwork downwards. This is especially true, for example, when forming the side wall of an inclined ramp or driveway that can run straight or curved at the same time.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Schaltafel der eingangs erwähnten Art zu schaffen, bei welcher eine sehr einfache Verlängerung der im Querschnitt etwa trapezförmig aufgebauten Träger trotz der an ihnen abstehenden Befestigungsflansche möglich ist. Die Lösung dieser Aufgabe besteht darin, daß die Träger aus zwei relativ zueinander in Längsrichtung verstellbaren, sich zumindest in einem Überlappungsbereich umgreifenden, U-förmi- gen Trägerteilen oder -abschnitten besteht, wobei der Schrägungswinkel der U-Schenkel des zumindest teilweise innen liegenden Trägerabschnittes mit der Schalhaut im Inneren seines Querschnittes gegenüber dem des ihn umgreifenden außen liegenden Trägerabschnittes stumpfer oder größer ist, und daß die lichte Weite zwischen den U-Schenkeln an der Schalhaut bei dem innen liegenden Trägerabschnitt zumindest um die Gesamtbreite der voneinander weggerichteten Befestigungsflansche geringer als bei dem außen liegenden Trägerabschnitt ist und daß die Befestigungsflansche beider Trägerabschnitte in der selben Ebene nebeneinander liegen.The invention is therefore based on the object of providing a formwork panel of the type mentioned at the outset in which a very simple extension of the cross-sectionally approximately trapezoidal supports is possible in spite of the fastening flanges projecting from them. The solution to this problem consists in the fact that the carrier consists of two U-shaped carrier parts or sections that are adjustable in the longitudinal direction relative to one another and encompass at least in an overlap region, the helix angle of the U-legs of the at least partially inner carrier section also the formwork skin inside its cross-section is blunt or larger than that of the outer support section encompassing it, and that the clear width between the U-legs on the formwork skin in the inner support section is at least smaller by the total width of the fastening flanges directed away from one another than in the case of the outside lying support section and that the mounting flanges of both support sections lie side by side in the same plane.
Es wird also trotz des Erfordernisses, an den U-Schenkeln jeweils nach außen abstehende Befestigungsflansche zum Anschließen an die Schalhaut vorzusehen, um die Trägerteile oder -abschnitte an der Schalhaut befestigen zu können und eforderlichenfalls eine gewisse Verformung zur Anpassung der Krümmung zuzulassen, erreicht, daß die Träger auf einfache Weise in ihrer Längsrichtung verlängert werden können. Zwar hat es im Schalungsbau schon teleskopartig auseinanderziehbare Trägerteile gegeben, bei denen dann aber die Innenquerschnitte der außen liegenden Abschnitte den Außenquerschnitten der innen liegenden Abschnitte entsprechen. Bei der erfindungsgemäßen Schaltafel weichen nun die Querschnitte der beiden Trägerabschnitte zur Berücksichtigung der Befestigungsflansche ganz erheblich dadurch voneinander ab, daß der von den U-Schenkeln jeweils eingeschlossene Winkel bei dem innen liegenden Trägerabschnitt spitzer als bei dem ihn umgreifenden Trägerabschnitt ist, so daß die Befestigungsflansche beider Trägerabschnitte jeweils voneinander abweichende Abstände haben und der außen liegende Trägerabschnitt den innen liegenden Trägerabschnitt zusammen mit dessen abstehenden Flanschen in sich aufnehmen kann. Dennoch ist dafür gesorgt, daß auch der innen liegende Trägerabschnitt noch - im Querschnitt gesehen - schräg auseinanderlaufende Schenkel hat, die bei einer Veränderung der Krümmung der Schaltafel mit ihren Befestigungsflanschen ohne bleibende Verformung bewegt werden können. Gleichzeitig ergibt sich eine entsprechend gute Aussteifung auch in dem Verlängerungsbereich. Eine solche Verlängerung kann bei vertikal angeordnetem Träger sowohl nach unten als auch nach oben erfolgen.Despite the requirement to provide outwardly projecting fastening flanges on the U-legs for connection to the formlining, in order to be able to fasten the carrier parts or sections to the formlining and, if necessary, to allow a certain deformation to adapt to the curvature, this is achieved the carriers can be easily extended in their longitudinal direction. In formwork construction there have already been telescopic support parts in which the inner cross sections of the outer sections correspond to the outer cross sections of the inner sections. In the formwork panel according to the invention, the cross sections of the two support sections to take the mounting flanges into account differ considerably from one another in that the angle enclosed by the U-legs is more acute in the internal support section than in the support section surrounding it, so that the mounting flanges of both Carrier sections each have different distances and the outer carrier section can accommodate the inner carrier section together with its protruding flanges. Nevertheless, it is ensured that the inner support section - seen in cross section - also obliquely diverging legs has, which can be moved with its mounting flanges without permanent deformation when the curvature of the formwork panel is changed. At the same time, a correspondingly good stiffening also results in the extension area. Such an extension can take place both vertically and vertically with the carrier arranged vertically.
Die U-Querstege der beiden teilweise ineinandergreifenden Trägerabschnitte können in Gebrauchsstellung aneinander liegen und miteinander lösbar verbindbar sein. An den U- Querstegen läßt sich auf einfache Weise die Kupplung oder Verbindung der beiden Trägerabschnitte durchführen, deren U- Schenkel aufgrund ihrer unterschiedlichen Winkel auseinanderlaufen. Zusätzlich ergibt sich natürlich auch noch eine Aussteifung über die Befestigung der Befestigungsflansche an der Schalhaut.The U-crossbars of the two partially interlocking support sections can lie against one another in the position of use and can be releasably connected to one another. The coupling or connection of the two support sections, the U-legs of which diverge due to their different angles, can be carried out in a simple manner on the U-transverse webs. In addition, of course, there is also stiffening by fastening the fastening flanges to the formlining.
Eine Verlängerung von ineinanderpassenden Trägerabschnitten läßt sich dadurch erreichen, daß sie zunächst gelöst und dann in einer anderen relativen Position zueinander wieder befestigt werden. Schneller und einfacher geht es jedoch, wenn die Trägerabschnitte in Längsrichtung des Trägers relativ zueinander verschiebbar sind und an den U-Querstegen wenigstens eines Trägerabschnittes eine Schiebeführung oderAn extension of mating carrier sections can be achieved by first loosening them and then reattaching them in another relative position. However, it is quicker and easier if the support sections can be displaced relative to one another in the longitudinal direction of the support and a sliding guide or at the U-transverse webs of at least one support section

Eine zweckmäßige Anordnung insbesondere bezüglich der gegen¬ seitigen Schiebeführung der Trägerabschnitte kann darin bestehen, daß an Lochungen des in GebrauchsStellung außen liegenden Trägerabschnittes einen radial vorstehenden Vorsprung oder Kopf aufweisende Befestigungselemente angreifen, wobei der Vorsprung oder Kopf im Inneren des Trägerabschnittes liegt und als Gegenführungsmittel die Ränder eines Langschlitzes oder dergleichen Führung des innen liegenden Trägerabschnittes untergreift, und daß das Befestigungselement gegenüber dem innen liegenden Trägerabschnitt verspannbar oder anziehbar ist. Die beiden Trägerabschnitte können also in ihrem Überlappungsbereich von solchen Befestigungselementen gemeinsam durchsetzt sein, die einerseits mit einem Vorsprung oder Kopf an dem innen liegenden Trägerabschnitt angreifen, der mit einem Langschlitz gegenüber diesem Kopf verschiebbar ist, aber durch Verspannen des Befestigungselementes auch in der jeweils eingestellten Position fixiert und festgeklemmt werden kann.An expedient arrangement, in particular with regard to the mutual sliding guide of the carrier sections, can consist in the fact that a perforated radially projecting projection or head is attached to the perforations of the carrier section lying on the outside in the use position, the projection or head lying inside the carrier section and the edges as counter-guiding means a slot or the like guidance of the inside engages the underlying support section, and that the fastening element can be braced or tightened with respect to the internal support section. The two support sections can thus be jointly penetrated in their overlap area by fastening elements which, on the one hand, engage with a projection or head on the inner support section, which can be displaced with an elongated slot relative to this head, but also by tensioning the fastening element in the respectively set position can be fixed and clamped.
Besonders günstig ist es, wenn das Befestigungselement an der Außenseite der Träger ein Gewinde und eine darauf anziehbare Mutter aufweist. Praktisch kann also als Befestigungselement eine Schraube mit nahezu beliebigem Kopf dienen, deren Kopf im Inneren als Gegenführungselement die Ränder des Längsschlitzes des innen liegenden Trägerabschnittes untergreift, während an der Außenseite eine übliche Gewindemutter in gelockertem Zustand das gegenseitige Verschieben bei der Längeneinstellung ermöglicht und in angezogenem Zustand die Trägerteile gegeneinander festlegt.It is particularly favorable if the fastening element has a thread on the outside of the carrier and a nut which can be tightened thereon. Practically, therefore, a screw with almost any head can serve as a fastening element, the head of which, under the inside as a counter-guiding element, engages underneath the edges of the longitudinal slot of the inner carrier section, while on the outside a conventional threaded nut in the loosened state enables mutual displacement during length adjustment and in the tightened state the carrier parts against each other.
Durch geeignete Maßnahmen kann dabei dafür gesorgt werden, daß sich der Vorsprung oder Kopf des Befestigungselementes beim Anziehen der Mutter nicht mitdrehen kann. Beispielsweise kann dieser Kopf entsprechende Flachseiten haben und in einer Aussparung so zu liegen kommen, daß seine Verdrehung verhin¬ dert ist.Appropriate measures can be taken to ensure that the projection or head of the fastening element cannot rotate when the nut is tightened. For example, this head can have corresponding flat sides and come to rest in a recess in such a way that its rotation is prevented.
Der innen liegende Trägerteil kann aus zwei etwa Z-förmigen, im Bereich des U-Quersteges einen Schlitzabstand zueinander aufweisenden Trägerprofilen zusammengesetzt sein, welche durch im Innenraum des U-Querschnittes befindliche Querverbinder oder Querbleche zusammengehalten sind. Auf diese Weise ergibt sich über die gesamte Länge des innen liegenden Trägerteiles ein durchgehender Führungsschlitz. Außerdem können die Z-förmigen Trägerprofile nach ihrer gegenseitigen Verbindung durch Querbleche insgesamt eine so große Steifigkeit haben, daß die im Verlängerungsbereich solcher Schaltafeln auftretenden Kräfte mit entsprechender Sicherheit aufgenommen werden können. Ein nachträgliches Ausfräsen eines Führungsschlitzes kann vermieden werden.The inner support part can be composed of two approximately Z-shaped support profiles which have a slot spacing from one another in the region of the U crossbar and which are held together by cross connectors or cross plates located in the interior of the U cross section. In this way, there is a continuous guide slot over the entire length of the inner carrier part. In addition, the Z-shaped support profiles after their mutual connection by means of transverse plates as a whole have great rigidity that the forces occurring in the extension area of such switchboards can be absorbed with corresponding certainty. Subsequent milling of a guide slot can be avoided.
Die Querverbinder oder Querbleche des innen liegenden Trägerabschnittes können im Bereich des Führungsschlitzes der Trägerabschnitte eine Aussparung haben, deren lichte Weite größer als die des Gegenführungsmittels oder des Kopfes des Befestigungselementes ist. Somit stellen diese Querbleche bei der Veränderung der Gesamtlänge des Trägers kein Hindernis dar. Das Befestigungselement kann eine Hammerkopfschraube sein, so daß beim Verspannen kein Gegenhalten an dem Kopf erforderlich ist, da dieser Hammerkopf aufgrund seiner Form an der Innenseite so anliegen kann, daß er sich nicht mitdreht.The cross connectors or cross plates of the inner support section can have a recess in the area of the guide slot of the support sections, the clear width of which is greater than that of the counter-guide means or the head of the fastening element. Thus, these cross plates do not represent an obstacle when changing the overall length of the beam. The fastening element can be a hammer head screw, so that no bracing is required on the head when bracing, since this hammer head, due to its shape, can lie against the inside so that it fits not turning.
Die Querverbinder oder Querbleche des innen liegenden Trägerteiles können auch den U-Quersteg - innenseitig - berühren und von diesem aus nur einen Teil der Querschnittslänge der U-Schenkel dieses Trägerabschnittes beaufschlagen. Dadurch wird einerseits eine genügend feste Verbindung der Z-förmigen Trägerprofile erreicht, andererseits aber die elastische Verformbarkeit der U- Schenkel aufrechterhalten. Die U-Schenkel der Trägerteile sind also ohne bleibende Verformung seitlich bewegbar und die Schaltafel ist um ein oder mehrere parallel zu dem oder den Trägern verlaufende Achsen krümmbar beziehungsweise in ihrer Krümmung veränderbar. Somit kann beispielsweise in einem Parkhaus bei einer schräg aufwärts führenden und gleichzeitige eine Kurve bildenden Fahrbahn die Seitenwand problemlos mit jeweils erforderlichen, der Biegung der Kurve entsprechenden Krümmungen geschalt werden, wobei gleichzeitig auch die Steigung der Fahrbahn durch entsprechend unterschiedliche Verlängerungen der Träger der Schaltafeln berücksichtigt werden kann.The cross connectors or cross plates of the inside support part can also touch the inside of the U crosspiece and act on it from there only a part of the cross-sectional length of the U-legs of this support section. On the one hand, this results in a sufficiently firm connection of the Z-shaped support profiles, but on the other hand maintains the elastic deformability of the U-legs. The U-legs of the carrier parts can thus be moved laterally without permanent deformation and the formwork can be curved or its curvature can be bent about one or more axes running parallel to the carrier or carriers. Thus, for example, in a multi-storey car park on a sloping upward and simultaneous lane-forming lane, the side wall can be easily formed with the required curvatures corresponding to the curve's bend, while the slope of the lane is also taken into account by correspondingly different extensions of the formwork panel supports can.
Um mit möglichst wenig Querverbindern oder Querblechen an dem innen liegenden Trägerabschnitt auskommen zu können, können die Querverbinder oder Querbleche einen Abstand zwischen sich haben, der wenigstens nahezu der Länge des Trägerabschnittes oder vorzugsweise etwas weniger als die Hälfte dieser Länge beträgt, und es können zwei oder drei Querverbinder oder Querbleche über die Länge des Trägerabschnittes so verteilt sein, daß jeweils nahe den stirnseitigen Enden und insbeson¬ dere in der Mitte des Trägerabschnittes jeweils ein solcher Querverbinder oder ein Querblech vorgesehen ist. Je nach Länge dieses in Gebrauchsstellung teilweise innen liegenden Trägerabschnittes können also entweder an seinen Enden solche Querverbinder vorgesehen sein oder es kann zusätzlich auch noch in der Mitte ein Querverbinder zur Verbesserung der gegenseitigen Aussteifung der Z-förmigen Trägerprofile angeordnet werden. Somit ist die Herstellung dieses zur Verlängerung dienenden Trägerabschnittes entsprechend einfach.In order to be able to make do with as few cross-connectors or cross-plates on the inside support section, the cross connectors or cross plates have a distance between them which is at least almost the length of the support section or preferably a little less than half this length, and two or three cross connectors or cross plates can be distributed over the length of the support section so that in each case close to the front ends and in particular in the middle of the support section such a cross connector or a cross plate is provided. Depending on the length of this support section, which is partially inside in the position of use, such cross connectors can either be provided at its ends or a cross connector can also be arranged in the middle to improve the mutual stiffening of the Z-shaped support profiles. Thus, the manufacture of this support section serving as an extension is correspondingly simple.
Insgesamt ergibt sich eine Schaltafel, die vor allem bei Verwendung in Rundungen in vorteilhafter Weise angewendet werden kann und eine Verlängerung nach oben und/oder unten in Erstreckungsrichtung der Aussteifungsträger ermöglicht. Die Verlängerungsteile haben dabei in vorteilhafter Weise eine ebenfalls trapezförmige, also insofern übereinstimmende geometrische Form wie die an der Schaltafel vorhandenen Trägerabschnitte oder Trapez-Träger, sind aber maßlich bezüg¬ lich ihres Querschnittes so abgewandelt, daß sie insbesondere stufenlos gegenüber diesen Trägerteilen verschiebbar sind, obwohl an ihren U-Schenkeln zur Verbindung mit der Schalhaut jeweils nach außen abstehende Flansche vorgesehen sind. Da die Führungsschlitze an den verschiebbaren Trägerabschnitten vorgesehen sind, ist auch eine Nachrüstung schon vorhandener, im Querschnitt etwa trapezförmige Aussteifungsträger aufweisender Schaltafeln möglich.Overall, there is a formwork panel, which can be used advantageously, particularly when used in curves, and enables an extension upwards and / or downwards in the direction of extension of the stiffening beams. The extension parts advantageously have a trapezoidal, that is to say insofar, corresponding geometric shape as the carrier sections or trapezoidal carriers present on the formwork panel, but are dimensionally modified with respect to their cross-section such that they are in particular continuously displaceable relative to these carrier parts, although flanges projecting outwards are provided on their U-legs for connection to the formlining. Since the guide slots are provided on the displaceable support sections, it is also possible to retrofit existing formwork panels which have a trapezoidal cross-section in cross-section.

Eine im ganzen mit 1 bezeichnete Schaltafel hat im Ausfüh¬ rungsbeispiel gemäß Figur 1 auf der dem Beton abgewandten Seite der Schalhaut 2 neben zwei Randstegen 3 zum Kuppeln mit Nachbarschaltafeln abstützende, im ganzen mit 4 -bezeichnete Träger, deren jeder einen etwa U-förmigen Querschnitt aufweist. Dabei erkennt man auch in Figur 2, daß die U- Schenkel 5 dieses die Schalhaut 2 auf der dem Beton abgewandten Seite abstützenden Trägers 4 durch einen U- Quersteg 6 mittelbar oder unmittelbar verbunden sind, welcher sich auf der von der Schalhaut 2 abgewandten Seite befindet. Die U-Schenkel 5 laufen dabei - im Querschnitt gesehen - von dem U-Quersteg 6 aus schräg auseinander und zwar symmetrisch zu einer senkrecht zur Schalhaut 2 stehenden Längsmittelebene. Sie haben also gegenüber der Schalhaut beziehungsweise dieser Längsmittelebene jeweils den selben Schrägungswinkel.In the exemplary embodiment according to FIG. 1, a formwork panel designated as a whole has 1 on the side of the formwork skin 2 facing away from the concrete, in addition to two edge webs 3 supporting for coupling with neighboring formwork panels, generally designated by 4 -beams, each of which has an approximately U-shaped cross section having. It can also be seen in FIG. 2 that the U-legs 5 of this support 4, which supports the formlining 2 on the side facing away from the concrete, are indirectly or directly connected by a U-transverse web 6, which is located on the side facing away from the formwork facing 2 . The U-legs 5 - seen in cross-section - run diagonally apart from the U-crosspiece 6 and that symmetrically to a longitudinal center plane perpendicular to the formlining 2. So they have the same helix angle in relation to the formlining or this longitudinal median plane.
An ihren freien Enden oder Rändern haben die U-Schenkel 5 jeweils - wiederum im Querschnitt gesehen - von den U- Schenkeln 5 nach außen abstehende und voneinander weggerichtete Befestigungsflansche 7 zum Angreifen an der Schalhaut 2, also zur Befestigung zum Beispiel mittels Schrauben.At their free ends or edges, the U-legs 5 each have - again seen in cross-section - fastening flanges 7 projecting outward from the U-legs 5 and directed away from one another for engaging on the formlining 2, i.e. for fastening, for example, by means of screws.
Vor allem anhand der Figur 2 in Verbindung mit den Figuren 7 bis 10 erkennt man, daß der jeweilige Träger 4 aus zwei relativ zueinander in Längsrichtung verstellbaren, sich zumindest in einem - analog verstellbaren - Überlappungsbe¬ reich umgreifenden Trägerteilen oder -abschnitten 4a und 4b besteht, wobei der Schrägungswinkel der U-Schenkel 5 des zumindest teilweise innen liegenden Trägerabschnittes 4b mit der Schalhaut 2 im Inneren seine Querschnittes gegenüber dem des ihn umgreifenden außen liegenden Trägerabschnittes 4a stumpfer oder größer ist. Umgekehrt ausgedrückt ist der Winkel zwischen den Schenkeln 4b kleiner oder spitzer als der zwischen den U-Schenkeln 4a. Daraus ergibt sich ein in Figur 2 deutlich erkennbarer spitzwinkliger Winkelraum WR zwischen den Schenkeln 5 des Trägerabschnittes 4a und denen des Trägerabschnittes 4b.Especially in connection with FIG. 2 in conjunction with FIGS. 7 to 10, it can be seen that the respective carrier 4 consists of two carrier parts or sections 4a and 4b which are adjustable in the longitudinal direction relative to one another and which encompass at least one - analogously adjustable - overlap area , wherein the helix angle of the U-leg 5 of the at least partially inner support section 4b with the formwork skin 2 inside its cross section is blunt or larger than that of the outer support section 4a surrounding it. Conversely, the angle between the legs 4b is smaller or more acute than that between the U-legs 4a. This results in an acute angular space WR, which can be clearly seen in FIG. 2, between the legs 5 of the carrier section 4a and those of the carrier section 4b.
Die lichte Weite zwischen den U-Schenkel 5 an der Stelle, an welcher sie mit der Schalhaut 2 verbunden sind oder werden, ist bei dem innen liegenden Trägerabschnitt 4b zumindest um die Gesamtbreite der voneinander weggerichteten Befestigungs- flansche 7 geringer als bei dem außen liegenden Trägerab¬ schnitt 4a. Die Befestigungsflansche 7 beider Trägerabschnitte 4a und 4b liegen nämlich in Gebrauchsstellung in der selben Ebene nebeneinander, solange die Schalhaut 2 nicht gekrümmt ist, sondern gemäß Figur 2 eben verläuft. Die einander jeweils unmittelbar benachbarten Befestigungsflansche 7 der Trägerabschnitte 4a und 4b liegen aber auch bei gekrümmter Schalhaut 2 etwa in einer übereinstimmenden tangentialen Ebene.The clear width between the U-legs 5 at the point at which they are or are connected to the formlining 2 is smaller in the inner support section 4b, at least by the total width of the fastening flanges 7 facing away from one another, than in the outer support section ¬ section 4a. The fastening flanges 7 of the two carrier sections 4a and 4b are in the use position in the same plane next to one another, as long as the formwork skin 2 is not curved, but rather runs according to FIG. The fastening flanges 7 of the carrier sections 4a and 4b, which are respectively directly adjacent to one another, also lie approximately in a corresponding tangential plane, even when the formwork skin 2 is curved.
Wichtig ist, daß durch unterschiedliche Schrägungswinkel der U-Schenkel 5 die beiden Trägerabschnitte 4a und 4b trotz der voneinander wegweisenden Befestigungsflansche 7 ineinanderpassen, aber eine seitliche Bewegbarkeit ohne bleibende Verformung haben, falls die Schaltafel 1 gekrümmt werden soll oder in ihrer Krümmung verändert werden soll. Die in Figur 1 dargestellte Schaltafel zeigt dabei an der Schalhaut 2 zwei Träger 4, die jeweils aus Trägerabschnitten 4a und 4b bestehen, wobei die U-Schenkel der Trägerabschnitte 4a und 4b - wie erwähnt - ohne bleibende Verformung seitlich bewegbar sind und die Schaltafel 1 um eine oder mehrere parallel zu dem oder den Trägern 4 verlaufende Achse krümmbar und in ihrer Krümmung veränderbar ist. Die dazu an den der Schalhaut 2 abliegenden Bereichen der Träger 4 angreifenden Mittel, zum Beispiel Spannschrauben, zur Veränderung und Festlegung der jeweiligen Krümmung der Schalhaut 2 sind nicht eingezeichnet, da es um deren Ausbildung nicht geht.It is important that due to different helix angles of the U-legs 5, the two support sections 4a and 4b fit into one another despite the mutually pointing away mounting flanges 7, but have lateral mobility without permanent deformation if the formwork panel 1 is to be curved or its curvature is to be changed. The formwork panel shown in FIG. 1 shows two girders 4 on the formwork skin 2, each consisting of girder sections 4a and 4b, the U-legs of the girder sections 4a and 4b - as mentioned - being movable laterally without permanent deformation and the formwork panel 1 around one or more axes running parallel to the carrier (s) 4 can be curved and their curvature can be changed. The means for this, which act on the areas of the carrier 4 lying away from the formwork skin 2, for example tensioning screws, for changing and fixing the respective curvature of the formwork skin 2 are not shown, since it is not a question of their formation.
Die U-Querstege 6 der beiden teilweise ineinandergreifenden Trägerabschnitte 4a und 4b liegen in Gebrauchsstellung gemäß Figur 2 aneinander, soweit sich die Trägerabschnitte 4a und 4b überlappen, und sind in diesem Bereich miteinander lösbar verbunden. Eine einmal eingestellte Verlängerung durch entsprechende relative Verschiebung der beiden Trägerabschnitte 4a und 4b in ihrer Längsrichtung kann also entsprechend festgelegt werden.The U-cross webs 6 of the two partially interlocking support sections 4a and 4b lie in the use position according to Figure 2 to each other, as far as the carrier sections 4a and 4b overlap, and are releasably connected to each other in this area. A once set extension by corresponding relative displacement of the two carrier sections 4a and 4b in their longitudinal direction can thus be determined accordingly.
Zwar könnten die Trägerabschnitte auch in unterschiedlichen Positionen relativ zueinander jeweils zusammengefügt werden, jedoch ist es für eine einfache Handhabung in den Ausführungsbeispielen in zweckmäßiger Weise vorgesehen, daß die Trägerabschnitte 4a und 4b in Längsrichtung des Trägers 4 relativ zueinander verschiebbar sind und an den U-Querstegen 6 eines Trägerabschnittes eine Schiebeführung oder Längsführung, insbesondere wenigstens ein Langschlitz vorgesehen ist.Although the carrier sections could also be joined together in different positions relative to one another, it is expediently provided for easy handling in the exemplary embodiments that the carrier sections 4a and 4b can be displaced relative to one another in the longitudinal direction of the carrier 4 and on the U-transverse webs 6 of a carrier section, a sliding guide or longitudinal guide, in particular at least one long slot, is provided.
Dabei wird anhand der Figuren 7 und 8 in Verbindung mit Figur7 and 8 in conjunction with FIG
5 und 6 sowie Figur 2 bis 4 deutlich, daß an Lochungen 8 des U-Quersteges 6 des in Gebrauchsstellung außen liegenden5 and 6 as well as FIGS. 2 to 4 clearly show that the perforations 8 of the U-crosspiece 6 are in the use position on the outside
Trägerabschnittes 4a einen radial vorstehenden Vorsprung oder Kopf 9 aufweisende Befestigungselemente 10 angreifen, wobei der Vorsprung oder Kopf 9 im Inneren des Trägerquerschnittes liegt und als Gegenführungsmittel die Ränder eines Langschlitzes 11, also einer Führung, des innen liegenden Trägerabschnittes 4b untergreift. Diese Befestigungselemente sind gegenüber dem innen liegenden Trägerabschnitt 4b an dem äußeren Trägerabschnitt 4a verspannbar oder anziehbar. Im Ausführungsbeispiel haben sie dazu an der Außenseite des Trägers 4 ein Gewinde und eine darauf verschraubbare und anziehbare Mutter 12. Denkbar wäre aber auch eine Verspannung mit Hilfe eines einen Schlitz des überstehenden Teiles des Befestigungselementes 10 durchsetzenden Keiles.Carrier section 4a engage a radially protruding projection or head 9 having fastening elements 10, the projection or head 9 being located inside the cross section of the support and engaging under the edges of an elongated slot 11, that is to say a guide, of the inside support section 4b as counter-guiding means. These fastening elements can be braced or tightened relative to the inner carrier section 4b on the outer carrier section 4a. In the exemplary embodiment, they have a thread on the outside of the carrier 4 and a nut 12 which can be screwed and tightened thereon. Conceivable would also be bracing with the aid of a wedge passing through a slot in the protruding part of the fastening element 10.
Der als Führung dienende Langschlitz 11 ist gemäß Figur 5 undThe slot 11 serving as a guide is shown in FIGS
6 an dem innen liegenden Trägerabschnitt 4b dadurch gebildet, daß dieser Trägerabschnitt 4b aus zwei etwa z-förmigen, im Bereich des U-Quersteges einen Schlitzabstand zueinander aufweisenden, spiegelsymmetrisch zur Längsmittelebene angeordneten Trägerprofilen zusammengesetzt ist, welche durch im Innenraum des U-QuerSchnittes befindliche Querverbinder oder Querbleche 13 zusammengehalten sind. Gegenüber einem aus einem Blech gebogenen, im Querschnitt etwa trapezförmigen Trägerabschnitt 4b, der anschließend mit Längsschlitzen an dem U-Quersteg 6 versehen werden müßte, wird also von vorneherein eine Fertigung aus zwei Einzelstücken durchgeführt, die zwischen sich den Längsschlitz 11 freilassen.6 formed on the inner support section 4b by the fact that this support section 4b consists of two approximately z-shaped, mirror-symmetrical to the longitudinal center plane in the region of the U-crosspiece, having a slot spacing from one another arranged support profiles is assembled, which are held together by cross connectors or cross plates 13 located in the interior of the U-cross section. Compared to a carrier section 4b which is bent from a sheet metal and is approximately trapezoidal in cross section and which would then have to be provided with longitudinal slots on the U-transverse web 6, production is therefore carried out from the start from two individual pieces which leave the longitudinal slot 11 free between them.
Die Querverbinder oder Querbleche 13 haben dabei gemäß Figur 5 sowie gemäß den Figuren 2 bis 4 im Bereich des Führungsschlitzes 11 eine Aussparung 14, deren lichte Weite größer als die des Gegenführungsmittels, also im Ausführungsbeispiel des Kopfes 9 des Befestigungselementes 10 ist. Somit kann der Trägerabschnitt 4b gegenüber dem Befestigungselement 10 und seinem Kopf 9 verschoben werden, solange die Verbindung noch gelockert ist, ohne daß ein Querblech 13 dies verhindert. Bei einer entsprechend großen Anzahl von Lochungen 8 an dem U-Quersteg 6 des außen liegenden Trägerabschnittes 4a kann also der in den Figuren 7 und 8 erkennbare Überlappungsbereich beispielsweise mit zwei Befestigungselementen 10 festgelegt werden.According to FIG. 5 and FIGS. 2 to 4, the cross connectors or cross plates 13 have a recess 14 in the region of the guide slot 11, the clear width of which is greater than that of the counter-guide means, that is to say in the exemplary embodiment of the head 9 of the fastening element 10. Thus, the carrier section 4b can be moved relative to the fastening element 10 and its head 9 as long as the connection is still loosened without a transverse plate 13 preventing this. With a correspondingly large number of perforations 8 on the U-crosspiece 6 of the outer support section 4a, the overlap area which can be seen in FIGS. 7 and 8 can thus be fixed, for example, with two fastening elements 10.
Figur 2 bis 4 zeigt unterschiedliche Ausbildungen des Kopfes 9. Gemäß Figur 2 kann das Befestigungselement 10 eine Hammer¬ kopfschraube sein, die also einen entsprechend geformten Kopf hat, der sich beim Verdrehen der Mutter 12 nicht mitdreht, sofern er in einer entsprechenden Aussparung gehalten ist. Es ist aber auch möglich, daß der unmittelbar an den Kopf 9 angeschlossene Schaftbereich eine solche Mehrkantform hat, daß er gegenüber dem Längsschlitz 11 nicht verdreht werden kann. Zur Verbesserung der Übertragung der Klemmkräfte von der Mutter 9 auf die U-Querstege 6 ist dabei unter der Mutter 12 und einer Unterlegscheibe 15 noch eine Stützplatte 16 angeordnet, deren Breite etwa der Breite der U-Querstege 6 entspricht. Gemäß Figur 2 und 5 berühren die Querverbinder oder Querbleche 13 des innen liegenden Querträgerabschnittes 4b auch den U-Quersteg 6 von innen her und Beaufschlagen von diesem aus nur einen Teil der Querschnittslänge der U- Schenkel 5 dieses Trägerabschnittes 4b, so daß die U-Schenkel 5 die schon erwähnte seitliche Bewegbarkeit auch im Bereich dieser Querbleche 13 weitgehend behalten.2 to 4 show different designs of the head 9. According to FIG. 2, the fastening element 10 can be a hammer-head screw, which therefore has a correspondingly shaped head which does not turn when the nut 12 is turned, provided that it is held in a corresponding recess . However, it is also possible that the shaft region directly connected to the head 9 has such a polygonal shape that it cannot be rotated relative to the longitudinal slot 11. To improve the transmission of the clamping forces from the nut 9 to the U-crosspieces 6, a support plate 16 is arranged under the nut 12 and a washer 15, the width of which corresponds approximately to the width of the U-crosspieces 6. According to Figures 2 and 5, the cross connector or cross plates 13 of the inner cross member section 4b also touch the U-cross bar 6 from the inside and act on it from only part of the cross-sectional length of the U-leg 5 of this carrier section 4b, so that the U-leg 5 largely retain the lateral mobility already mentioned, also in the area of these transverse plates 13.
Dabei genügt es, wenn die Querverbinder oder Querbleche 13 in Längsrichtung des Trägerabschnittes 4b gemäß Figur 6 einen Abstand zwischen sich haben, der wenigstens nahezu der Länge dieses Trägerabschnittes 4b entspricht. Für eine verbesserte Stabilität kann der Abstand jedoch etwas geringer als die Hälfte dieser Länge des Trägerabschnittes 4b sein. Auf jeden Fall sind jeweils nahe den stirnseitigen Enden des Trägerab¬ schnittes 4b solche Querbleche 13 vorhanden. Dies gilt sowohl für den Fall, daß zwei Querbleche 13 als auch drei Querbleche 13 oder eventuell noch mehr solche Querbleche 13 über die Länge des Trägerabschnittes 4b verteilt sind. Im Ausführungs- beispiel ist neben den beiden nahe den Enden vorgesehenen Querblechen 13 noch in der Mitte des Trägerabschnittes 4b ein solches Querblech 13 vorgesehen. Dabei erkennt man in Figur 6 noch die Lochungen 17 in den Befestigungsflanschen 7, durch welche Befestigungsmittel wie Schrauben und Nägel hindurch in die Schalhaut 2 eingreifen können.It is sufficient if the cross connectors or cross plates 13 have a distance between them in the longitudinal direction of the support section 4b according to FIG. 6, which distance corresponds at least almost to the length of this support section 4b. For improved stability, however, the distance can be somewhat less than half this length of the carrier section 4b. In any case, such transverse plates 13 are present near the front ends of the carrier section 4b. This applies both in the event that two transverse plates 13 and three transverse plates 13 or possibly even more such transverse plates 13 are distributed over the length of the carrier section 4b. In the exemplary embodiment, in addition to the two transverse plates 13 provided near the ends, such a transverse plate 13 is also provided in the center of the carrier section 4b. 6 shows the perforations 17 in the fastening flanges 7, through which fastening means such as screws and nails can engage in the formlining 2.
Bei der Schaltafel gemäß Figur 7 oder 8 sind im Gegensatz zu der nach Figur 1 vier Träger 4 vorgesehen, wobei Figur 7 eine Anordnung zeigt, bei welcher diese Träger 4 nach oben hin durch Herausziehen der innen liegenden Trägerabschnitte 4b jeweils um den gleichen Betrag verlängert sind. Eine derartige Schaltafel 1 ist also um eine gleichbleibende Breite nach oben verlängert.In the form of the panel according to FIG. 7 or 8, in contrast to that according to FIG. 1, four carriers 4 are provided, FIG. 7 showing an arrangement in which these carriers 4 are each extended by the same amount by pulling out the inner carrier sections 4b . Such a formwork panel 1 is thus extended upwards by a constant width.
Figur 8 verdeutlicht bei einer derartigen Schaltafel 1 mit vier Trägern 4, daß die Träger 4 - wie in allen übrigenFigure 8 illustrates in such a formwork panel 1 with four supports 4 that the supports 4 - as in all the others
Ausführungsbeispielen auch - auch nach unten verlängert werden können, wobei die Verlängerung jedes einzelnen TrägersEmbodiments too - can also be extended downwards, the extension of each individual carrier
4 unterschiedlich sein kann. Gemäß Figur 8 nimmt beispielsweise die Verlängerung von links nach rechts zu, so daß eine daran angebrachte Schalhaut an ihrem unteren Rand schräg verläuft, um beispielsweise eine Fahrrampe und deren Steigung zu berücksichtigen, neben welcher mit Hilfe der Schaltafel 1 eine Begrenzungswand betoniert werden soll.4 can be different. According to Figure 8 takes For example, the extension from left to right, so that an attached formlining runs obliquely at its lower edge, for example, to take into account a driving ramp and its slope, next to which a boundary wall is to be concreted with the help of formwork panel 1.
Betrachtet man die in Figur 7 und 8 jeweils teilweise darge¬ stellten Schaltafeln als eine gemeinsame Schaltafel, wird deutlich, daß diese sowohl nach unten als auch nach oben verlängert werden kann, wobei auch nach oben hin ein schräger Randabschluß durch unterschiedlich lange Verlängerungen erzielt werden könnte. Die Schrägung könnte dabei parallel zu der unteren oder auch entgegengesetzt geneigt sein. Es ergibt sich also eine vielfältige Anpassungsmöglichkeit, bei der lediglich das jeweilige Schalhautstück im Bereich der vorstehenden Trägerabschnitte 4b unter Umständen angepaßt werden muß. Die Vergrößerung einer Schaltafel 1 ist jedoch sehr einfach für eine Bedienungsperson durchführbar, weil sie in die Trägerabschnitte 4a lediglich Trägerabschnitte 4b einsetzen muß oder dort schon vorhandene Trägerabschnitte 4b entsprechend weit herausziehen und dann befestigen muß, um die Abstützung für eine Aufstockung der Schaltafel und der Schalhaut 2 möglich zu machen. Dabei bleibt die Möglichkeit erhalten, die Schaltafel 1 krümmen zu können und dabei auch die Krümmung verändern zu können, selbst wenn die gesamte Schaltafel 1 in der beschriebenen Weise verlängert wird. Solche Schaltafeln 1 lassen sich also zum Beispiel beim Bauen von Tiefgaragen und deren Zufahrtrampen einsetzen, wo nicht selten schräge untere oder obere Wandabschlüsse durch die Auffahrrampen entstehen. Da solche Fahrrampen gleichzeitig Kurven machen können, ist es besonders günstig, daß die Träger 4 und ihre Trägerabschnitte 4a und 4b eine Krümmung beziehungsweise Änderung der Krümmung der Schaltafel 1 zulassen.If one considers the formwork panels shown partially in FIGS. 7 and 8 as a common formwork panel, it becomes clear that this can be extended both downwards and upwards, whereby an inclined edge closure could also be achieved by extensions of different lengths . The slope could be parallel to the lower one or also inclined in the opposite direction. This results in a wide range of adaptations, in which only the respective piece of formlining in the area of the above support sections 4b may have to be adapted. However, the enlargement of a formwork panel 1 can be carried out very easily for an operator because it only has to insert carrier portions 4b into the carrier portions 4a or pull out already existing carrier portions 4b there accordingly and then fasten it in order to support the top-up of the formwork panel and the formlining 2 to make possible. The possibility remains to be able to bend the formwork panel 1 and also to be able to change the curvature, even if the entire formwork panel 1 is extended in the manner described. Such switchboards 1 can thus be used, for example, when building underground garages and their access ramps, where it is not uncommon for inclined lower or upper wall closures to be created by the ramps. Since such travel ramps can make curves at the same time, it is particularly favorable that the supports 4 and their support sections 4a and 4b permit a curvature or change in the curvature of the formwork panel 1.
Die Schaltafel 1 hat eine Schalhaut 2 und diese auf der dem Beton abgewandten Seite abstützende Träger 4 sowie gegebenen¬ falls etwa parallel zu den Trägern 4 verlaufende Randstege 3, womit nebeneinanderstehende Schaltafeln 1 miteinander gekup- pelt und verbunden werden können. Die Träger 4 haben einen etwa u-förmigen Querschnitt, wobei die U-Schenkel 5 von einem U-Quersteg 6 ausgehend schräg auseinanderlaufen und an ihren freien Enden, wo ihr gegenseitiger Abstand am größten ist, voneinander wegweisende Befestigungsflansche 7 zum Verbinden mit der Schalhaut 2 haben. Für eine Verlängerung der Schalta¬ fel nach wenigstens einer in Fortsetzung der Längserstreckungsrichtung der Träger 4 liegenden Seite besteht der jeweilige Träger 4 aus zwei relativ zueinander in Längsrichtung verstellbaren, sich zumindest in einem Überlap¬ pungsbereich umgreifenden Trägerteilen oder Trägerabschnitten 4a und 4b, wobei der Schrägungswinkel der U-Schenkel des innen liegenden Trägerabschnittes 4b mit der Schalhaut 2 im Inneren seines Querschnittes gegenüber dem entsprechenden Winkel des ihn umgreifenden Trägerabschnittes 4a stumpfer oder größer ist beziehungsweise der zwischen den beiden U- Schenkeln liegende Winkel des inneren Trägerabschnittes 4b spitzer als der entsprechende Winkel zwischen den U-Schenkeln 5 des außen liegenden Trägerabschnittes 4a ist. Die Winkel sind so gewählt, daß bei aneinanderliegenden U-Querstegen 6 die lichte Weite zwischen den U-Schenkeln 5 an der Schalhaut 2 bei dem innen liegenden Trägerabschnitt 4b etwa um die Gesamtbreite der voneinander weggerichteten Befestigungsflansche 7 geringer als die lichte Weite bei dem außen liegenden Trägerabschnitt 4a an gleicher Stelle ist, so daß die Befestigungsflansche 7 beider Trägerabschnitte bei ebener Schalhaut 2 in derselben Ebene nebeneinander liegen. The formwork panel 1 has a formwork skin 2 and this support 4 on the side facing away from the concrete and, if appropriate, edge webs 3 running approximately parallel to the supports 4, with which adjacent formwork panels 1 are coupled to one another. pelt and can be connected. The carriers 4 have an approximately U-shaped cross-section, the U-legs 5 starting from a U-cross bar 6 at an angle and at their free ends, where their mutual distance is greatest, fastening flanges 7 pointing away from one another for connection to the formlining 2 to have. For an extension of the formwork panel to at least one side lying in the continuation of the longitudinal direction of the supports 4, the respective support 4 consists of two support parts or support sections 4a and 4b which are adjustable in the longitudinal direction relative to one another and which at least overlap in an overlap area, the helix angle the U-leg of the inner support section 4b with the formlining 2 inside its cross-section is blunt or larger than the corresponding angle of the support section 4a encompassing it or the angle of the inner support section 4b lying between the two U-legs is more acute than the corresponding angle between the U-legs 5 of the outer support section 4a. The angles are chosen so that when the U crosspieces 6 are adjacent to one another, the clear width between the U legs 5 on the formlining 2 in the inner support section 4b is approximately less by the total width of the fastening flanges 7 facing away from one another than the clear width in the outer case Carrier section 4a is in the same place, so that the fastening flanges 7 of both carrier sections lie next to one another in the same plane when the formlining 2 is flat.
