Description

Die Erfindung bezieht sich auf eine Schalung zum Herstellen von Betonbauteilen entsprechend dem Oberbegriff des Patentanspruchs1.The invention relates to a formwork for the production of concrete components according to the preamble of claim 1.

Zum Herstellen von Betonbauteilen unterschiedlichster Art und dabei insbesondere auch zum Herstellen von Fundamenten sind Schalungen bekannt, die als Schalungselemente (Schalhaut) ein Verbundmaterial verwenden, welches aus einem Gittermaterial (Baustahlmatte) als Träger und aus wenigstens einer auf dieses Gittermaterial aufgebrachten Kunststoff-Folie (Schrumpffolie) besteht. Speziell zum Herstellen von Fundamenten oder Balken aus Beton wird dabei als verlorene Schalung ein Schalungselement verwendet, welches aus diesem Verbundmaterial durch Biegen derart hergestellt ist, daß es in Schalungslängsrichtung einen U-förmigen Querschnitt aufweist, der von zwei parallel und im Abstand voneinander verlaufenden Seitenflächen und einer unteren, diese Seitenflächen miteinander verbindenden Jochfläche gebildet ist, wobei die Seitenflächen durch mehrere Abstandshalter miteinander verbunden sind.For the production of various types of concrete components, and in particular also for the manufacture of foundations, formwork is known which uses a composite material as formwork elements (formlining), which consists of a grid material (structural steel mat) as a support and at least one plastic film (shrink film) applied to this grid material ) consists. Especially for the production of foundations or beams made of concrete, a formwork element is used as the lost formwork, which is made from this composite material by bending such that it has a U-shaped cross section in the longitudinal direction of the formwork, which consists of two parallel and spaced side surfaces and a lower yoke surface connecting these side surfaces is formed, the side surfaces being connected to one another by a plurality of spacers.

Aus dem genannten Verbundmaterial lassen sich zwar Schalungen für Betonbauteile, insbesondere auch verlorene Schalungen mit der unterschiedlichsten, an den jeweiligen Verwendungszweck angepaßten Form preiswert herstellen, und zwar bei geringem Flächengewicht und damit einfacher Handhabung des Schalungselementes; ein gewisser Nachteil besteht jedoch darin, daß das Verbundmaterial nur eine relativ geringe Biegesteifigkeit gegenüber senkrecht zu den Oberflächen dieses Verbundmaterials wirkenden Kräften aufweist, so daß beispielsweise bei dem vorstehend erwähnten U-förmigen Schalungselement zum Herstellen von Fundamenten oder Balken eine relativ große Anzahl von Distanzhaltern erforderlich ist, die dann mit relativ geringem gegenseitigen Abstand in Schalungslängsrichtung sowie in einer Richtung senkrecht hierzu (in vertikaler Richtung) angeordnet werden müssen, um ein Ausbauschen der Schalung aufgrund des Gewichtes des in die Schalung eingebrachten Betons zu vermeiden.From the composite material mentioned, formwork for concrete components, in particular also lost formwork with a wide variety of shapes adapted to the respective intended use, can be produced inexpensively, with a low basis weight and thus easy handling of the formwork element; a however, there is a certain disadvantage in that the composite material has only a relatively low bending stiffness in relation to forces acting perpendicular to the surfaces of this composite material, so that, for example, a relatively large number of spacers is required for the manufacture of foundations or beams in the case of the U-shaped formwork element mentioned above , which must then be arranged with a relatively small mutual distance in the longitudinal direction of the formwork and in a direction perpendicular to it (in the vertical direction) in order to avoid the formwork from being swapped out due to the weight of the concrete introduced into the formwork.

Aufgabe der Erfindung ist es, eine Schalung der eingangs geschilderten Art so auszubilden, daß sie unter Beibehaltung eines möglichst geringen Gewichts und damit einer einfachen Handhabung eine verbesserte Steifigkeit in bezug auf das als Schalhaut verwendete Verbundmaterial aufweist.The object of the invention is to form a formwork of the type described in such a way that it has an improved rigidity with respect to the composite material used as formwork skin while maintaining the lowest possible weight and thus simple handling.

Zur Lösung dieser Aufgabe ist eine Schalung entsprechend dem kennzeichnenden Teil des Patentanspruchs 1 ausgebildet.To solve this problem, a formwork is designed according to the characterizing part of claim 1.

Unter "raumgitterartig oder Gitterträgerart" ist im Sinne der Erfindung eine Ausbildung zu verstehen, bei der die wenigstens drei Längsstäbe im Querschnitt des Aussteifungselementes derart gegeneinander versetzt sind, daß sie die Eckpunkte eines Dreiecks oder Vielecks bilden.In the sense of the invention, “space lattice-like or lattice girder type” is to be understood as a configuration in which the at least three longitudinal bars in the cross section of the stiffening element are offset from one another in such a way that they form the corner points of a triangle or polygon.

Durch das raumgitterartig ausgebildete Aussteifungselement wird die Steifigkeit des wenigstens einen Schalungselementes wesentlich verbessert, wobei speziell auch das Aussteifungselement preiswert gefertigt werden kann und nur ein geringes Gewicht aufweist, so daß auch die Schalung insgesamt preiswert und mit einem die Handhabung erleichternden geringen Gewicht hergestellt werden kann.The stiffness of the at least one formwork element is substantially improved by the stiffening element designed like a space lattice, wherein in particular, the stiffening element can also be manufactured inexpensively and has only a low weight, so that the formwork as a whole can also be manufactured inexpensively and with a low weight that facilitates handling.

Durch das Aussteifungselement ist es weiterhin speziell bei zum Herstellen von Balken oder Fundamenten verwendeten U-förmigen Schalungselementen möglich, die Anzahl der Distanzhalter zu reduzieren bzw. den gegenseitigen Abstand solcher Distanzhalter zu vergrößern, so daß sich hierdurch bei gleicher Steifigkeit der Schalung eine wesentliche Vereinfachung der Herstellung und Kostenreduzierung ergeben.Through the stiffening element, it is also possible, particularly in the case of U-shaped formwork elements used for the manufacture of beams or foundations, to reduce the number of spacers or to increase the mutual spacing of such spacers, so that this considerably simplifies the formwork with the same rigidity Manufacturing and cost reduction result.

Bei einer Ausführungsform der Erfindung ist an wenigstens einer von dem Schalungselement gebildeten Fläche der Schalung zumindest ein Aussteifungselement derart befestigt, daß sich dieses an dieser Fläche anliegend in Schalungslängsrichtung erstreckt.In one embodiment of the invention, at least one stiffening element is fastened to at least one surface of the formwork formed by the formwork element in such a way that it extends adjacent to this surface in the longitudinal formwork direction.

Bei einer anderen Ausführungsform der Erfindung, bei der wenigstens zwei jeweils eine Schalungsfläche bildende Schalungselemente in größerem Abstand voneinander angeordnet sind, ist wenigstens ein Aussteifungselement vorgesehen, welches mit seiner Längserstreckung senkrecht bzw. quer zu diesen Flächen zwischen den beiden Schalungselementen angeordnet ist. Bei dieser Ausführungsform ist vorzugsweise zu dem wenigstens einen, senkrecht bzw. quer zu den Flächen der Schalung angeordneten Aussteifungselement noch jeweils wenigstens ein weiteres Aussteifungselement an jeder Fläche vorgesehen, welches gegen diese Fläche anliegt und sich in Längsrichtung des betreffenden Schalungselementes erstreckt. Sind bei dieser Ausführungsform mehrere, den Raum zwischen den beiden Schalungselementen bzw. Flächen der Schalung überbrückende und senkrecht bzw. quer zu diesen Schalungsflächen verlaufende Aussteifungselemente vorgesehen, so können diese gleichzeitig auch als Auflage für eine ebenfalls aus dem Verbundmaterial hergestellte Schalungsfläche bzw. Schalhaut dienen, die dann zur Herstellung einer anschließenden Betondecke verwendet wird.In another embodiment of the invention, in which at least two formwork elements each forming a formwork surface are arranged at a greater distance from one another, at least one stiffening element is provided which, with its longitudinal extent, is arranged perpendicularly or transversely to these surfaces between the two formwork elements. In this embodiment, in addition to the at least one stiffening element arranged perpendicularly or transversely to the surfaces of the formwork, at least one further stiffening element is provided on each surface, which rests against this surface and extends in the longitudinal direction of the relevant formwork element. In this embodiment, there are several Provided space between the two formwork elements or surfaces of the formwork bridging and perpendicular or transverse to these formwork stiffening elements, they can also serve as a support for a formwork surface or formlining also made of the composite material, which then for the production of a subsequent concrete floor is used.

In den Fig. ist 1 ein Schalungselement, welches durch Biegen aus einem Verbund-Material hergestellt ist. Dieses Verbundmaterial besteht aus einem Gitterwerk bzw. -material als Träger, welches von einer üblichen Baustahlmatte mit sich kreuzenden und an den Kreuzungspunkten miteinander verbundenen Armiereisen bzw. Baustählen 2 und 3 gebildet ist, sowie aus zwei beidseitig auf dem Gittermaterial aufgeschrumpften Kunststoff-Folien 4, welche das Gittermaterial beidseitig abdecken und damit auch die Gitteröffnungen dieses Materials verschließen und im Bereich der Gitteröffnungen miteinander verschweißt sind.In the figures, 1 is a formwork element which is produced by bending from a composite material. This composite material consists of a latticework or material as a carrier, which is formed by a conventional structural steel mat with reinforcing bars or structural steels 2 and 3 which cross and are connected to one another at the crossing points, and from two plastic foils 4 shrunk on both sides of the lattice material, which cover the mesh material on both sides and thus also close the mesh openings of this material and are welded to one another in the region of the mesh openings.

Das Schalungselement 1, welches z.B. zum Herstellen von Balken oder Fundamenten aus Beton dient, ist aus dem Verbundmaterial so gebogen, daß es einen U-förmigen Querschnitt aufweist, d.h. zwei vertikale, im Abstand voneinander angeordnete Seitenflächen 5 und 6 sowie eine diese Seitenflächen miteinander verbindende untere Boden- bzw. Jochfläche 7 aufweist, wobei die Biegekante zwischen den Seitenflächen 5 und 6 und der Bodenfläche 7 jeweils parallel zu den Baustählen 2 sowie senkrecht zu den an diesen Biegekanten umgewinkelten Baustählen 3 verläuft.The formwork element 1, which is used for example for the production of beams or foundations made of concrete, is from the Composite material bent so that it has a U-shaped cross-section, ie two vertical, spaced side surfaces 5 and 6 and a lower floor or yoke surface 7 connecting these side surfaces, the bending edge between the side surfaces 5 and 6 and the bottom surface 7 runs parallel to the structural steels 2 and perpendicular to the structural steels 3 angled at these bending edges.

Um dem Schalungselement 1 die notwendige Stabilität zu verleihen, d.h. beim Einbringen des Betons in den zwischen den Seitenflächen 5 und 6 gebildeten Schalungsraum ein Auseinanderbewegen der Seitenflächen 5 und 6 zu vermeiden, sind mehrere, senkrecht zu den Seitenflächen verlaufende und letztere druck- und zugfest miteinander verbindende Distanzhalter 8 vorgesehen, die in vertikaler Richtung übereinander und auch in Längsrichtung des Schalungselementes 1, d.h. senkrecht zur Zeichenebene der Fig. 1 hintereinander angeordnet sind.In order to give the formwork element 1 the necessary stability, i.e. When placing the concrete in the formwork space formed between the side surfaces 5 and 6 to prevent the side surfaces 5 and 6 from moving apart, a plurality of spacers 8 are provided which run perpendicular to the side surfaces and connect the latter to one another in a pressure-resistant and tensile manner also in the longitudinal direction of the formwork element 1, ie are arranged one behind the other perpendicular to the plane of the drawing in FIG. 1.

Jeder Distanzhalter besteht aus einem stabförmigen Element 9 aus Eisen oder Stahl, welches an jedem Ende mit einem gabelförmigen Abschnitt 10 mit jeweils zwei Schenkeln 11 ausgebildet ist. Die Schenkel 11 jedes Abschnitts 10 sind parallel und im Abstand voneinander angeordnet und erstrecken sich in Längsrichtung des Elementes 9. Die Länge jedes Schenkels 11 ist gleich einem Mehrfachen des Durchmessers der Baustähle 2 und 3, d.h. bei der dargestellten Ausführungsform größer als der dreifache Durchmesser dieser Baustähle. Die gabelförmigen Abschnitte 10 sind beispielsweise aus Flachstahl durch Biegen hergestellt und im Bereich des die Schenkel 11 verbindenden Jochabschnittes 12 mit dem jeweiligen Ende des Elementes 9 verbunden bzw. verschweißt.Each spacer consists of a rod-shaped element 9 made of iron or steel, which is formed at each end with a fork-shaped section 10 with two legs 11 each. The legs 11 of each section 10 are arranged parallel and at a distance from one another and extend in the longitudinal direction of the element 9. The length of each leg 11 is equal to a multiple of the diameter of the structural steels 2 and 3, that is to say in the illustrated embodiment, greater than three times the diameter thereof Structural steels. The fork-shaped sections 10 are, for example, made of flat steel by bending and in the region of the yoke section 12 connecting the legs 11 with the each end of the element 9 connected or welded.

In jedem Schenkel 11 ist eine von Bohrungen 13, 13′ und 13˝ gebildete und in Längsrichtung des Schenkels angeordnete Lochreihe vorgesehen, wobei jede Bohrung 13, 13′ bzw. 13˝ an einem Schenkel 11 einer entsprechenden Bohrung am anderen Schenkel 11 deckungsgleich gegenüberliegt. Mit ihren Schenkeln 11 druchdringen die Abschnitte 10 jeweils die beiden Schrumpffolien 4, so daß die Schenkel 11 jeweils über die Außenfläche des Schalungselementes 1 vorstehen. Weiterhin umfassen die Schenkel 11 jedes Abschnittes 19 jeweils einen Baustahl 2.In each leg 11 is formed by holes 13, 13 'and 13' and arranged in the longitudinal direction of the leg row of holes, each bore 13, 13 'and 13' on one leg 11 of a corresponding hole on the other leg 11 is congruent. With their legs 11, the sections 10 penetrate the two shrink films 4, so that the legs 11 each protrude beyond the outer surface of the formwork element 1. Furthermore, the legs 11 of each section 19 each comprise a structural steel 2.

Um das Verbundmaterial bzw. die von diesem gebildeten Seitenflächen 5 und 6 auch in dem Bereich, der zwischen zwei in Schalungslängsrichtung aufeinander folgenden Distanzhaltern 8 liegt, abzustützen bzw. dort ein seitliches Ausbauchen der Schalung zu vermeiden, sind bei der dargestellten Ausführungsform an den Außenseiten der Seitenflächen 5 und 6 jeweils zwei, in Längsrichtung der Schalung bzw. des Schalungselementes 1 verlaufende und übereinander angeordnete Aussteifungselemente 14 vorgesehen. Jedes Aussteifungselement 14 besteht aus drei sich in Längsrichtung des Aussteifungselementes 14 erstreckenden Längsstäben bzw. Baustählen 15-17, die bei der dargestellten Ausführungsform den gleichen Durchmesser wie die Baustähle 2 und 3 aufweisen und parallel zueinander und im Abstand voneinander derart angeordnet sind, daß sie im Querschnitt des Aussteifungselementes 14 die Eckpunkte eines gleichseitigen Dreiecks bilden, dessen kürzere Basis zwischen den Baustählen 15 und 16 und dessen größere Schenkel zwischen den Baustählen 15 und 17 bzw. 16 und 17 gebildet sind. Die Baustähle 15 - 17 sind durch mehrere, jeweils V-förmig gebogene, ebenfalls aus Baustahl hergestellte Elemente 18 zum dem gitterträgerartigen Aussteifungselement 14 miteinander verbunden. Jedes Aussteifungselement 14 ist an der Außenfläche der betreffenden Seitenfläche 5 bzw. 6 so angeordnet, daß es mit seinen Baustählen 15 und 16 an der Außenfläche anliegt bzw. dieser unmittelbar benachbart ist, wobei bei der dargestellten Ausführungsform der Baustahl 15 oberhalb des Baustahls 16 liegt. Gehalten wird jedes Aussteifungselement 14 an der betreffenden Seitenfläche 5 bzw. 6 dadurch, daß der Baustahl 15 ebenfalls zwischen den beiden Schenkeln 11 der Distanzhalter 8 aufgenommen ist. Durch einen Bolzen oder Nagel 19, der beispielsweise durch die sich deckenden Bohrungen 13′ des betreffenden Abschnittes 10 hindurchgeht, sind der Baustahl 15 bzw. das Aussteifungselement 14 gegen Heraus- bzw. Herunterrutschen an den Abschnitten 10 der Distanzhalter 8 gesichert.In order to support the composite material or the side surfaces 5 and 6 formed by it, also in the area that lies between two spacers 8 following one another in the longitudinal direction of the formwork, or to avoid lateral bulging of the formwork there, in the embodiment shown on the outside of the Side surfaces 5 and 6 each have two stiffening elements 14 which run in the longitudinal direction of the formwork or the formwork element 1 and are arranged one above the other. Each stiffening element 14 consists of three longitudinal rods or structural steels 15-17 extending in the longitudinal direction of the stiffening element 14, which in the illustrated embodiment have the same diameter as the structural steels 2 and 3 and are arranged parallel to one another and at a distance from one another such that they are in the Cross section of the stiffening element 14 form the corner points of an equilateral triangle, the shorter base between the structural steels 15 and 16 and the larger leg between the structural steels 15 and 17 or 16 and 17 are formed. The structural steels 15-17 are connected to one another by a plurality of elements 18, each of which is bent in a V-shape and also made of structural steel, for the lattice girder-like stiffening element 14. Each stiffening element 14 is arranged on the outer surface of the respective side surface 5 or 6 so that it rests with its structural steels 15 and 16 on the outer surface or is immediately adjacent, the structural steel 15 being above the structural steel 16 in the embodiment shown. Each stiffening element 14 is held on the relevant side surface 5 or 6 in that the structural steel 15 is also received between the two legs 11 of the spacers 8. By a bolt or nail 19, for example, through the overlapping bores 13 'of the section 10 in question, the structural steel 15 and the stiffening element 14 are secured against slipping out or down on the sections 10 of the spacers 8.

Durch die Aussteifungselemente 14, die durch ihre oben beschriebene Ausbildung und Anordnung an den Seitenflächen 5 bzw. 6 auch in Belastungsrichtung (senkrecht zu diesen Seitenflächen) ein besonders hohes Trägheitsmoment aufweisen, ist es auch möglich, den Abstand, den die Distanzhalter 8 in Längsrichtung des Schalungselementes 1 (senkrecht zur Zeichenebene der Fig. 1) voneinander aufweisen, größer zu wählen, als dies ohne die Verwendung der Aussteifungselemente 14 möglich wäre.Due to the stiffening elements 14, which have a particularly high moment of inertia in the loading direction (perpendicular to these side surfaces) due to their configuration and arrangement described above on the side surfaces 5 and 6, it is also possible to determine the distance that the spacers 8 have in the longitudinal direction of the Formwork element 1 (perpendicular to the drawing plane of FIG. 1) from each other to choose larger than would be possible without the use of the stiffening elements 14.

In den Fig. 6 und 7 ist eine weitere Ausführungsform dargestellt. Bei dieser Ausführungsform besteht die Schalung aus wenigstens zwei in einem größeren Abstand voneinander angeordneten Schalungselementen 1′, die wiederum aus dem gleichen Verbundmaterial wie das Schalungselement 1 hergestellt sind. Der einfacheren Darstellung wegen ist in den Fig. 6 und 7 nur eines der beiden Schalungselemente 1′ wiedergegeben. Dieses ist Bestandteil einer Beton-Schalung zum Herstellen eines Beton-Fundamentes, wobei bei der dargestellten Ausführungsform das Schalungselement 1′ ebenfalls einen U-förmigen Querschnitt aufweist, so daß mit zwei derartigen Schalungselementen 1′ zwei parallele und im Abstand voneinander angeordnete Balkenfundamente oder Abschnitte hiervon hergestellt werden können. Der zwischen den beiden Schalungselementen 1′ liegende Raum ist durch mehrere, in Längsrichtung dieser Schalungselemente, d.h. in Richtung senkrecht zur Zeichenebene der Fig. 6 hintereinander angeordnete Aussteifungselemente 14 überbrückt, die mit ihrer Längserstreckung jeweils senkrecht zu den einander zugewendeten Seitenflächen 6 der beiden Schalungselemente 1′ liegen und mit ihren beiden Enden jeweils in den zur Aufnahme des Betons dienenden Formraum 24 der beiden Schalungselemente 1 durch die Seitenfläche 6 hineinreichen, und zwar bei der dargestellten Ausführungsform unmittelbar im Bereich der oberen Längskante der Schalungselemente 1′. Die Aussteifungselemente 14 sind in geeigneter Weise (z.B. durch Anbinden) an den Baustählen 2 und/oder 3 der Seitenflächen 6 der beiden Schalungselemente 1′ gehalten. Die Aussteifungselemente 14 durchdringen jeweils die Schrumpffolien 4′ im Bereich einer Gitteröffnung oder aber im Bereich einer vergrößerten Öffnung, die durch Herausschneiden einer Teillänge zumindest eines der Baustähle 2 oder 3 im Bereich der Durchrittsstelle für das Aussteifungselement 14 geschaffen wurde. Durch die Aussteifungselemente 14 wird eine gegenseitige Abstützung der beiden, im Abstand voneinander angeordneten Schalungselemente 1′ erreicht, wobei sämtliche Aussteifungselemente 14 nach dem Einbringen des Betons in die Formräume 24 der Schalungselement 1′ in diesen Beton eingebettet sind, so daß es dann nach dem Herstellen der beiden Balkenfundamente bzw. deren Abschnitte möglich ist, auf die Aussteifungselemente 14 ein Flachmaterial 25, nämlich das bereits beschriebene Verbundmaterial aufzulegen, welches dann die untere, horizontale Schalungswand bzw. Schalungshaut für eine anschließend zu erstellende Decke aus Beton bildet. Die Schalung nach den Fig. 6 und 7 kann somit insbesondere als verlorene Schalung für die Herstellung von Betonwänden oder -fundamenten mit darüber anschließender Betondecke verwendet werden. Selbstverständlich ist es zweckmäßig, zusätzlich zu den den Raum zwischen den Schalungsselementen 1′ überbrückenden Aussteifungselementen 14 auch noch solche vorzusehen, die entsprechend den Fig. 1 bis 5 an den Seitenflächen 5 und 6 der Schalungselemente 1′ anliegen.A further embodiment is shown in FIGS. 6 and 7. In this embodiment, the formwork consists of at least two at a greater distance Formwork elements 1 'arranged from each other, which in turn are made of the same composite material as the formwork element 1. For the sake of simplicity, only one of the two formwork elements 1 'is shown in FIGS. 6 and 7. This is part of a concrete formwork for producing a concrete foundation, and in the embodiment shown, the formwork element 1 'also has a U-shaped cross section, so that with two such formwork elements 1' two parallel and spaced-apart beam foundations or sections thereof can be produced. The space between the two formwork elements 1 'is bridged by a plurality of stiffening elements 14 arranged one behind the other in the longitudinal direction of these formwork elements, that is to say in the direction perpendicular to the plane of the drawing in FIG. 6, each with its longitudinal extension perpendicular to the mutually facing side surfaces 6 of the two formwork elements 1 'Lie and extend with their two ends in the mold cavity 24 for holding the concrete of the two formwork elements 1 through the side surface 6, in the embodiment shown directly in the region of the upper longitudinal edge of the formwork elements 1'. The stiffening elements 14 are held in a suitable manner (for example by tying) to the structural steels 2 and / or 3 of the side surfaces 6 of the two formwork elements 1 '. The stiffening elements 14 each penetrate the shrink films 4 'in the area of a lattice opening or in the area of an enlarged opening, which was created by cutting out a partial length of at least one of the structural steels 2 or 3 in the area of the passage point for the stiffening element 14. Through the stiffening elements 14 mutual support of the two formwork elements 1 'arranged at a distance from one another, all stiffening elements 14 being embedded in this concrete after the introduction of the concrete into the mold spaces 24 of the formwork element 1', so that it is then after the two beam foundations or whose sections are possible to place a flat material 25, namely the already described composite material, on the stiffening elements 14, which then forms the lower, horizontal formwork wall or formwork skin for a concrete slab to be subsequently created. The formwork according to FIGS. 6 and 7 can thus be used in particular as lost formwork for the production of concrete walls or foundations with a concrete ceiling above it. Of course, it is expedient, in addition to the space between the formwork elements 1 'bridging stiffening elements 14 to also provide those which are in accordance with FIGS. 1 to 5 on the side surfaces 5 and 6 of the formwork elements 1'.

Wie in Fig. 5 dargestellt ist, können die Distanzhalter 8 bzw. deren Abschnitte 10 auch dazu verwendet werden, zwei sich in Längsrichtung der Schalung, d.h. senkrecht zur Zeichenebene der Fig. 1 aneinander anschließende und sich im Anschlußbereich an den Seitenflächen 5 und 6 sowie an der Jochfläche 7 auf einer Teillänge überlappende Schalungselemente 1 bzw 1′ miteinander zu verbinden. Hierfür sind dann zwischen den Schenkeln 11 der entsprechenden Distanzhalter 8 jeweils zwei benachbarte Baustähle 2 der beiden Schalungslemente im Anschluß- bzw. im Überlappungsbereich sowie auch der Baustahl 15 des Aussteifungselementes 14 aufgenommen, wobei der zur Sicherung dienende Nagel 19 durch die Bohrung 13˝ der beiden Schenkel 11 hindurchgesteckt ist.As shown in Fig. 5, the spacers 8 or their sections 10 can also be used to two in the longitudinal direction of the formwork, i.e. 1 adjacent to each other and in the connection area on the side surfaces 5 and 6 and on the yoke surface 7 on a partial length overlapping formwork elements 1 and 1 'to connect. For this purpose, two adjacent structural steels 2 of the two formwork elements in the connection or in the overlap area and also the structural steel 15 of the stiffening element 14 are then received between the legs 11 of the corresponding spacers 8, the nail 19 serving to secure them through the bore 13 'of the two Leg 11 is inserted.
