An insulating plate (P) can be fixed to the protective surface on the opposite side to the spacers. The protective surface can be a strip with lengthwise and transverse struts with a sheet-metal plate fixed between them and preferably of expanded metal to form the apertures. The spacers are fixed and preferably welded to the struts.

Description

Die Erfindung betrifft ein Schalungselement der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a formwork element in the preamble of claim 1 specified Art.

Zum formschlüssigen Anschließen einer Ortbeton-Decke an eine stehende Betonwand wird, wie z.B. aus FR-A-2 644 823 bekannt, im Anschlußbereich eine zurückspringende Auflageschulter in der stehenden Betonwand geformt. Zu diesem Zweck wird ein aus Brettern oder Styroporteilen geformtes Schalungselement in die Schalung der stehenden Betonwand integriert, z.B. ein Schalungselement in Kastenform. Nach dem Befüllen und Verdichten des Betons in der Schalung wird dieses Schalungselement wieder entfernt, um einen einwandfreien Deckenanschluß zu erzielen. Das Anfertigen, Einsetzen und Entfernen des Schalungselementes ist arbeitsintensiv und kostenaufwendig, zumal das Schalungselement jeweils maßgeschneidert werden muß. Gegebenenfalls wird dann in der Auflageschulter eine Dämmplatte montiert, um einer Rißbildung im Anschlußbereich der Deckplatte vorzubauen. Dies ist zeitaufwendig.For the positive connection of an in-situ concrete ceiling to one standing concrete wall, e.g. known from FR-A-2 644 823, in the connection area a recessed Support shoulder shaped in the standing concrete wall. To for this purpose, a molded from boards or polystyrene parts Formwork element in the formwork of the standing concrete wall integrated, e.g. a formwork element in box form. After filling and compacting the concrete in the formwork this formwork element is removed again to ensure that it is in perfect working order To achieve ceiling connection. The making, inserting and removing the formwork element is labor intensive and expensive, especially since the formwork element in each case must be tailored. If necessary, then in the Support shoulder mounted an insulation board to prevent cracking to be built in the connection area of the cover plate. This is time consuming.

Der Erfindung liegt die Aufgabe zugrunde, ein Schalungselement der eingangs genannten Art zu schaffen, mit dem sich universell die jeweils gewünschte Auflageschulter mit geringem Arbeits- und Kostenaufwand herstellen läßt.The invention has for its object a formwork element to create the kind mentioned above, with which universal the desired support shoulder with low working and can produce costs.

Die gestellte Aufgabe wird mit einem Schalungselement mit den Merkmalen des Patentanspruchs 1 gelöst.The task is achieved with a formwork element with the features of the claim 1 solved.

Das verlorene Schalungselement braucht nicht mehr aus der stehenden Betonwand entfernt zu werden. Es wird nach Anschluß der Decke kraftübertragend eingebunden, ohne die Verbindung zwischen der Decke und der stehenden Wand zu beeinträchtigen. Das Schalungselement ist in der gewünschten Größe leicht vorzufertigen bzw. auch an der Baustelle einfach an die bestehenden Anforderungen anzupassen. Es wird mit den Abstandhaltern am Bewehrungsteil oder an Bewehrungsteilen festgelegt, z.B. durch Rödeln oder Anschweißen. Beton wird vor und hinter der Abschirmfläche bis auf das gewünschte Niveau der Auflageschulter eingefüllt und verdichtet. Dann wird weiter Beton hinter der Abschirmfläche durch die Einfüll-Durchgänge eingefüllt und verdichtet. Die Durchbrechungen der Abschirmfläche ermöglichen eine kraftschlüssige Verbindung zwischen dem Beton und der Abschirmfläche sowie einen einwandfreien Anschluß der Decke, und vor allem den Luftaustritt beim Verdichten des Betons. Die Durchbrechungen sind in Form und Größe so ausgebildet, daß der Beton beim Einfüllen und Verdichten nicht unbehindert durchtritt. Unerwarteterweise verhindert die Konsistenz des Betons, auch beim Verdichten, daß der Beton vor der Abschirmfläche an der Schalung hochsteigt bzw. in nennenswertem Maß durch die Durchbrechungen hindurchtritt. Das Schalungselement ist stabil und läßt sich mittels der Abstandhalter so stabil festlegen, daß es seine Lage unter den groben Arbeitsbedingungen beim Einfüllen und Verdichten des Betons nicht verändert.The lost formwork element no longer needs to be removed from the standing concrete wall to be removed. It will after connection the ceiling integrated power transmission without the connection between the ceiling and the standing wall. The formwork element is easy to prefabricate in the desired size or simply at the construction site to the existing ones Adapt requirements. It comes with the spacers fixed on the reinforcement part or on reinforcement parts, e.g. by kneading or welding. Concrete is in front of and behind the shielding surface to the desired level of the support shoulder filled and compacted. Then concrete continues filled behind the shielding surface through the filling passages and condensed. The openings in the shielding surface enable a non-positive connection between the concrete and the shielding surface as well as a perfect connection the ceiling, and especially the air outlet when compressing the Concrete. The openings are designed in shape and size so that the concrete is not unimpeded when filling and compacting passes. The consistency unexpectedly prevents of the concrete, even when compacting, that the concrete before Shielding surface rises on the formwork or in significant Dimension passes through the openings. The formwork element is stable and can be removed using the spacers set so stable that it will be among the rough ones Working conditions when filling and compacting the concrete not changed.

Um einer späteren Rißbildung im Anschlußbereich der Decke entgegenzuwirken, wird manchmal in der Auflageschulter wenigstens eine Dämmplatte angebracht. Zweckmäßigerweise ist diese Dämmplatte gemäß Anspruch 2 bereits am Schalungselement befestigt, wodurch Zeit, Arbeit und Kosten gespart werden.For later crack formation in the connection area of the ceiling counteracting it is sometimes at least in the support shoulder an insulation board attached.

Die Längs- und Querstreben mit dem Streckmetall sind ein unter dem Handelsnamen "Stremaform" ® (eingetragenes Warenzeichen) bekanntes Produkt, das in beliebigen Größen und Formaten sowie Flächengewichten erhältlich ist. Die Abstandhalter lassen sich rasch und dauerhaft festlegen, zweckmäßigerweise an den Längs- und Querstreben des Stremaform-Streifens. Die die Durchbrechungen aufweisende Blechplatte verzahnt sich mit dem Beton, wobei der Beton nicht ungehindert durchdringen kann, um die Auflageschulter an der bestimmten Form und Größe freizuhalten. Jedoch kann beim Verdichten des Betons die enthaltende Luft ausgetrieben werden, wobei zweckmäßigerweise der weitgehende Luftaustrieb anhand durch die Durchbrechungen getretener Schlempe feststellbar ist.The embodiment according to claim 3 expediently builds on basic components known in this technology. The Longitudinal and cross struts with the expanded metal are one under the trade name "Stremaform" ® (registered trademark) well-known product that in any size and format as well Basis weights are available. Leave the spacers commit themselves quickly and permanently to the Longitudinal and cross struts of the Stremaform strip. The the Sheet metal plate with perforations interlocks with the Concrete, whereby the concrete cannot penetrate unhindered, to keep the support shoulder free from the specific shape and size. However, when compacting the concrete, it can contain Air are expelled, expediently the Extensive air expulsion based on the penetrations through the openings Schlempe is noticeable.

Sie lassen zwischen sich große Betoneinfüll-Durchgänge frei.The bow shapes according to claim 6 are simple Suitable handling and allow a stable fixation of the formwork element. They leave large concrete filling passages between them free.

Zwecks haltbarer Befestigung des Schalungselements in mehreren, beabstandeten Befestigungsstellen ist eine horizontale Anordnung der Bügel gemäß Anspruch 7 zweckmäßig.For permanent fastening of the formwork element in several, spaced attachment points is a horizontal one Arrangement of the bracket according to claim 7 useful.

Bei der Ausführungsform gemäß Anspruch 8 wird eine hohe Kippsicherheit des Schalungselements gewährleistet.In the embodiment according to claim 8, a high level of security against tipping guaranteed of the formwork element.

Das Merkmal von Anspruch 9 ist vorteilhaft, weil sich weit beabstandete Abstützpunkte am Bewehrungsteil der stehenden Wand ergeben, und auch bei Bewehrungsteilen mit grobem Raster genügend Anlagestellen für die Bügel des Schalungselementes entstehen. The feature of claim 9 is advantageous because it is wide spaced support points on the reinforcement part of the standing Wall, and also for reinforcement parts with a coarse grid enough contact points for the brackets of the formwork element arise.

Gemäß Anspruch 10 können die Abstandhalter auch aus Flacheisen gebildet sein, die gegebenenfalls so gebogen sind, daß sie sich am Bewehrungsteil einhängen lassen. Denkbar ist es dabei, die Abstandhalter vor Ort relativ zur Abstandfläche nachzubiegen, um eine Feineinstellung des Abstands der Abschirmfläche vom Bewehrungsteil bzw. der Tiefe der Auflageschulter vorzunehmen.According to claim 10, the spacers can also be made of flat iron be formed, which are optionally bent so that they can be attached to the reinforcement part.

Die Ausführungsform gemäß Anspruch 14 ist besonders zweckmäßig, weil der aufsteigende Beton sicher am zu weiten Aufsteigen gehindert wird. Die weitere Abschirmfläche kann, falls erforderlich, mit eigenen Abstandhaltern oder direkt an weiteren Bewehrungsteilen der stehenden Betonwand festgelegt werden, wodurch sich eine sehr stabile Lage des Schalungselementes ergibt. Es reicht in der Praxis aber auch aus, die weitere Abschirmfläche nur an dem Schalungselement selbt zu befestigen.The embodiment according to claim 14 is particularly useful because the ascending concrete will surely rise too far is prevented. The further shielding surface can, if required, with your own spacers or directly to others Reinforcement parts of the standing concrete wall set be, which results in a very stable position of the formwork element results.

Zum Herstellen einer stehenden, bewehrten Betonwand W wird eine Schalung aus Schalungswänden 1, 2 gemäß Fig. 1 hergestellt, die die späteren Außenseiten der Wand W definiert. Zwischen den Schalungswänden 1, 2 sind Bewehrungsteile 3, 4 (nur zwei sind gezeigt) positioniert, z.B. Baustahlmatten. Um eine Decke (in Fig. 1 nicht gezeigt) anschließen zu können, wird ein Hohlraum 8 ausgespart, der in der fertigen Betonwand W gemäß Fig. 2 eine Auflageschulter S für den Deckenanschluß begrenzt. Zu diesem Zweck ist ein verlorenes Schalungselement E an wenigstens einem Bewehrungsteil 4 festgelegt, z.B. durch Rödeln oder Anschweißen in Bereichen 12. Das verlorene Schalungselement E besteht aus einer in etwa vertikal anzuordnenden Abschirmfläche 10 und aus von deren Rückseite abstehenden Abstandhaltern 11, die sich bis zum oder in den Bewehrungsteil 4 erstrecken und dort - wie erwähnt - festgelegt sind. Die Abstandhalter 11 sind so ausgebildet, daß sie Betoneinfüll-Durchgänge 19 freilassen, die sich von oben nach unten erstrecken. Die Abschirmfläche 10 ist mit Durchbrechungen versehen, wie später erläutert wird.To produce a standing, reinforced concrete wall W is a Formwork made from formwork walls 1, 2 according to FIG. 1, which defines the later outer sides of the wall W. Between the formwork walls 1, 2 are reinforcement parts 3, 4 (only two are shown) positioned, e.g. Structural steel mats. Around a blanket (Not shown in Fig. 1) to be able to connect Cavity 8 recessed in the finished concrete wall W according to Fig. 2 limited a support shoulder S for the ceiling connection. For this purpose, a lost formwork element E is at least a reinforcement part 4, e.g. by rotting or welding in areas 12. The lost formwork element E consists of an approximately vertical shielding surface 10 and from spacers protruding from the rear 11, which are up to or in the reinforcement part 4 extend and there - as mentioned - are fixed. The spacers 11 are designed to have concrete filling passages 19 leave free, which extend from top to bottom. The shielding surface 10 is provided with openings, as will be explained later.

Zunächst wird Beton 5 von oben vor und hinter der Abschirmfläche 10 eingefüllt und gegebenenfalls verdichtet, bis ein Niveau 6 erreicht ist. Danach wird Beton 5' nur mehr durch die Durchgänge 19 von oben eingefüllt und verdichtet. Dabei steigt das Niveau des Betons vor der Abschirmfläche 10 ggfs. geringfügig an (bei 7 strichliert angedeutet).First, concrete 5 is placed in front of and behind the shielding surface 10 filled and compressed if necessary until a level 6 is reached. After that, concrete is only 5 'by the Passages 19 filled and compressed from above. This increases the level of the concrete in front of the shielding surface 10 may be slightly on (indicated by dashed lines at 7).

Nachdem der Beton ausgehärtet ist, werden die Schalungswände 1, 2 entfernt. Das Schalungselement E bleibt in der Wand W. Die später angefertigte oder angesetzte Decke D greift in die Auflageschulter S ein und wird auf übliche Weise, gegebenenfalls auch an die Bewehrungsteile, z.B. 3, angeschlossen.After the concrete has hardened, the formwork walls 1, 2 removed. The formwork element E remains in the wall W. The blanket D made or attached later engages in the Support shoulder S and is in the usual way, if necessary also to the reinforcement parts, e.g. 3, connected.

Gemäß Fig. 3 weist das Schalungselement E als Abschirmfläche 10 einen Streifen 15 mit Längs- und Querstreben 16, 17 und einer dazwischen befestigten Platte 13 mit Durchbrechungen 14) auf. Zweckmäßigerweise besteht die Platte 13 aus Streckmetall, z.B. 1 mm dick, mit 16 x 6 mm großen Durchbrechungen. Die Abschirmfläche 10 ist z.B. ein handelsübliches "Stremaform"-Element (eingetragenes Warenzeichen der Firma Peca-Verbundtechnik GmbH). Die Abstandhalter 11, von denen über die Länge und in Höhenrichtung des Streifens 15 mehrere vorgesehen sind, sind bei 18 mit den Längsstreben 17 beispielsweise verschweißt. Zwischen den Abstandhaltern 11 sind die Betoneinfüll-Durchgänge 19 frei.3, the formwork element E has a shielding surface 10 a strip 15 with longitudinal and transverse struts 16, 17 and one plate 13 secured therebetween with openings 14) on. The plate 13 expediently consists of expanded metal, e.g. 1 mm thick, with 16 x 6 mm openings. The shielding surface 10 is e.g. a commercially available "Stremaform" element (registered trademark of Peca-Verbundtechnik GmbH). The spacers 11, of which on the Length and in the vertical direction of the strip 15 several provided are, for example, welded to the longitudinal struts 17 at 18. Between the spacers 11 are the concrete filling passages 19 free.

Fig. 5 zeigt eine Perspektivansicht des Schalungselementes E von Fig. 3 mit Blick auf die Rückseite der Abschirmfläche 10. Die Abstandhalter 11 sind aus Baustahlstäben gebogene Bügel 20 mit beispielsweise in der Fig. 5 in ausgezogenen Linien angedeuteter Trapez-, Rechteck- oder S-Form, wobei entweder die freien Schenkelenden 21 und 22 an den Längsstreben 17 befestigt sind, so daß der Mittelabschnitt 23, der einen langgestreckten Abstützabschnitt bildet, im Abstand von der Abschirmfläche 10 verläuft, oder jeweils der Mittelabschnitt 23 an den Längsstreben 17 befestigt, z.B. festgeschweißt, ist, so daß die freien Schenkelenden 21 im Abstand von der Abschirmfläche 10 liegen und langgestreckte Abstützabschnitte bilden.5 shows a perspective view of the formwork element E. 3 with a view of the rear of the shielding surface 10. The spacers 11 are brackets 20 which are bent from structural steel rods with, for example, indicated in solid lines in FIG. 5 Trapezoidal, rectangular or S-shaped, with either the free leg ends 21 and 22 attached to the longitudinal struts 17 are so that the central portion 23 of an elongated Support section forms, at a distance from the shielding surface 10 runs, or in each case the central section 23 attached to the longitudinal struts 17, e.g. welded is like that that the free leg ends 21 at a distance from the shielding surface 10 lie and form elongated support sections.

Strichliert ist in Fig. 5 angedeutet, daß die Bügel 20 auch in Vertikalrichtung angeordnet sein können. Denkbar ist es, entweder nur horizontal verlaufende oder nur vertikal verlaufende Bügel vorzusehen, oder sowohl horizontal verlaufende als auch vertikal verlaufende Bügel oder schräg zur Längsrichtung des Streifens verlaufende Bügel.Dashed lines in Fig. 5 indicate that the bracket 20 also in Can be arranged vertically. It is conceivable, either only horizontal or only vertical Provide stirrups, or both horizontal as well vertically running bracket or at an angle to the longitudinal direction of the Stripes on the temples.

Alternativ könnten die Abstandhalter 11 gebogene Flacheisen 24 (strichliert angedeutet in Fig. 5) sein, die sich mit umgebogenen Enden in den Bewehrungsteil 4 einhaken lassen. Alternatively, the spacers 11 could be curved flat irons 24 (dashed lines in Fig. 5), which are bent with Let the ends hook into the reinforcement part 4.

Die Höhe und die Länge der Abschirmfläche 10 richten sich nach der gewünschten Größe der Auflageschulter S. Die Länge der Abstandhalter bzw. der Abstand zwischen der Abschirmfläche 10 und der vorderen Schalungswand 1 in Fig. 1 richten sich nach der Tiefe der gewünschten Auflageschulter.The height and the length of the shielding surface 10 depend on one another the desired size of the support shoulder S. The length of the spacers or the distance between the shielding surface 10 and the front formwork wall 1 in Fig. 1 depend the depth of the desired support shoulder.

Die Ausführungsform gemäß Fig. 4 unterscheidet sich von der Ausführungsform des Schalungselementes E gemäß Fig. 3 durch eine weitere, in etwa horizontal anzuordnende Abschirmfläche 10', die die untere Begrenzung der Auflageschulter S definiert und an der Abschirmfläche 10 bzw. am Streifen 15 befestigt ist. Die weitere Abschirmfläche 10' ist zweckmäßigerweise in ihrer Struktur und ihrem Aufbau gleich der Abschirmfläche 10 gemäß Fig. 5. D.h., sie kann aus einem Streifen 15 und daran befestigtem Streckmetall 13 (Stremaform) bestehen.4 differs from that Embodiment of the formwork element E according to FIG. 3 by another shielding surface to be arranged approximately horizontally 10 ', which defines the lower limit of the support shoulder S. and attached to the shielding surface 10 or to the strip 15 is. The further shielding surface 10 'is expediently in their structure and structure are the same as the shielding surface 10 5, that is, it can consist of a strip 15 and thereon attached expanded metal 13 (Stremaform) exist.

Die Abschirmfläche 10 könnte Streckmetall alleine sein, wobei die Abstandhalter 11 direkt an der Abschirmfläche befestigt sind. Anstelle einzelner Bügel 20 als Abstandhalter 11 könnten auch Baustahlabschlangen vorgesehen sein. Die Form und Ausbildung der Abstandhalter ist wie die Ausgestaltung der Abschirmfläche unerheblich, sofern sichergestellt ist, daß der eingefüllte Beton sich einerseits mit der Abschirmfläche verzahnen und entlüften kann, ohne ungehindert durchdringen zu können, und daß die Abstandhalter Betoneinfüll-Durchgänge 19 zum Einfüllen und Verdichten des Betons frei lassen.The shielding surface 10 could be expanded metal alone, whereby the spacers 11 are attached directly to the shielding surface are. Instead of individual brackets 20 as spacers 11 could structural steel coils can also be provided. The shape and training the spacer is like the design of the shielding surface irrelevant if it is ensured that the filled Concrete interlock with the shielding surface and can vent without being able to penetrate freely, and that the spacers concrete filling passages 19 for filling and compacting the concrete.

Bei der in Fig. 3 angedeuteten Alternative des Schalungselementes E ist an der Abschirmfläche 10 eine Dämmplatte P festgelegt, beispielsweise festgeklebt oder mit mechanischen Hilfsmitteln angebracht, z.B. an den Querstreben 16. Die Dämmplatte P hat die Aufgabe, im Deckenanschluß eine Rißbildung zu verhindern oder zu unterdrücken, die bei einer Betonverbindung zwischen der Decke und der stehenden Wand auftreten kann. Die Dämmplatte P kann aus z.B. 2,0 oder 3,0 cm starkem Polystyrol-Hartschaum oder aus Mineralwolle bestehen. Sie ist zweckmäßigerweise im Abstand vor der Abschirmfläche 10 angeordnet, um die Durchbrechungen 14 nicht zu verschließen, so daß beim Verdichten des Betons die Luft austreten kann.In the alternative of the formwork element indicated in FIG. 3 E an insulation plate P is fixed on the shielding surface 10, for example glued or with mechanical Aids attached, e.g. on the cross struts 16. The insulation board P has the task of cracking in the ceiling connection prevent or suppress that at a concrete joint between the ceiling and the standing wall. The Insulation board P can e.g. 2.0 or 3.0 cm thick rigid polystyrene foam or consist of mineral wool. It is convenient spaced in front of the shielding surface 10 in order not to close the openings 14, so that during compression air can escape from the concrete.

Bei der Ausführungsform gemäß Fig. 4 kann ebenfalls die Dämmplatte P vor der Abschirmfläche 10 festgelegt sein. Gegebenenfalls ist auch auf der zusätzlichen Abschirmfläche 10' eine Dämmplatte P' angebracht.In the embodiment according to FIG. 4, the insulation board can also P can be fixed in front of the shielding surface 10. Possibly is also on the additional shielding surface 10 ' Insulation board P 'attached.

Um im Anschlußbereich die häufig erforderlichen Übergreifungslängen in der Bewehrung zu schaffen, können Anschlußbewehrungsteile (Fig. 6), bei 26 strichliert angedeutet, durch das Schalungselement E geführt und von diesen abgestützt sein. Diese Teile 26 werden auf übliche Weise mit den anderen Bewehrungsteilen 3, 4 verbunden, und auch mit Bewehrungsteilen (nicht gezeigt) der Decke D. Die Teile 26 können U-förmige Bügel oder S-förmige Bügel sein, die sich durch Öffnungen 25 in der Abschirmfläche einfädeln lassen. Gegebenenfalls wird das Schalungselement E von vornherein mit positionierten Teilen 26 fertiggestellt oder zumindest mit den Öffnungen 25, um an der Baustelle vor Ort die Teile 26 nach Wunsch einsetzen zu können. Zweckmäßigerweise werden die Öffnungen 26 in einem vorbestimmten Raster im Schalungselement E vorbereitet, z.B. paarweise übereinanderliegende Bohrungen mit einem Zwischenabstand von ca. 150 mm.To the overlap lengths often required in the connection area in the reinforcement can create connecting reinforcement parts (Fig. 6), indicated by dashed lines at 26, by the Formwork element E guided and supported by these. These parts 26 are in the usual way with the other reinforcement parts 3, 4 connected, and also with reinforcement parts (not shown) the ceiling D. The parts 26 may have U-shaped brackets or S-shaped bracket, which through openings 25 in the shielding surface to thread. If necessary, that will Formwork element E from the start with positioned parts 26 completed or at least with the openings 25 to the Construction site to use the parts 26 as desired. The openings 26 are expediently arranged in a predetermined manner Prepared grid in formwork element E, e.g. in pairs bores one above the other with a spacing of approx. 150 mm.
