Abstract

This invention concerns a form element with two form panels which are connected by means of spacers (Q) and proposes providing, at least in the spacers (Q), a longitudinal through hole which is sealed off from filler material placed between the panels. In a wall construction with such form elements, stabilising elements, such as straightening rails (RS), can be held and braced by means of connecting elements (G) which pass through the longitudinal holes in the wall. The connecting elements (G) can be easily removed. The form elements are preferably made of separately produced form panels and of spacers (Q) inserted into said panels.

Bei dem in FIG 3 skizzierten Schalungselement bilden beim Einsetzen des Abstandshaltens in die Aussparungen T diese einen vertikalen Endanschlag für die Endplatten EP und/oder über die Taschenboden TB für das Mittelteil M und gewahrleisten so auf einfache Weise eine definierte Lage des eingesetzten ιo Abstandshalters und damit auch der Langsachse des Langsiochs bezüglich der Schalungsplatten Dies erlaubt bereits bei der Herstellung der getrennten Schalungsplatten die Erzeugung von Markierungen M an der Außenfläche FA an den Positionen der Verlängerung der Längsachse des Längslochs R im eingesetzten Zustand eines Abstandshalters.In the formwork element sketched in FIG. 3, when the spacing is inserted into the recesses T, these form a vertical end stop for the end plates EP and / or via the pocket bottom TB for the middle part M and thus ensure in a simple manner a defined position of the spacer used and thus also the longitudinal axis of the Langsiochs with respect to the formwork panels. This allows already in the manufacture of the separate Formwork panels the creation of marks M on the outer surface FA at the positions of the extension of the longitudinal axis of the longitudinal hole R in the inserted state of a spacer.
Durch Aufbohreπ oder Durchstoßen der Schalungsplatten an den Markierungen entstehen durchgehende Löcher durch das Schalungselement zur Aufnahme von Verbindungselementen. Anstelle der Markierungen können auch bereits bei der Herstellung der Schalungsplatten Durchgangslöcher realisiert werden.By drilling or piercing the formwork panels at the markings, through holes are created through the formwork element for receiving connecting elements. Instead of the markings, through holes can also be realized during the manufacture of the formwork panels.
In FIG. 8 ist eine Anordnung der in FIG. 3 skizzierten Art mit an den Außenflächen beider Schalungslatten angeordneten Richtschienen RS als Stabilisieruπgselementen abgebildet. Ein im skizzierten Beispiel stangenförmiges Verbindungselement, beispielsweise eine Gewindestange G, ist an den Stellen der Markierungen M durch die Restwaπdstärke der Schalungsplatten und im übrigen durch das Längsloch R des Abstandshalters geführt. Die Richtschienen RS weisen den Schalungselementen zugewandte Aussparungen SL auf, durch welche das Verbindungselement G ragt. Mittels Fixierungselementen wie z.B. einer Gewindemutter GM oder eines Keils K werden die Elemente in ihrer relativen Position zueinander festgelegt und vorzugsweise durch Zugbelastung des Verbindungselements G, welcher eine Druckbelastung des Abstandshalters entgegenwirkt, gegeneinander verspannt. In FIG. 8 is an arrangement of the arrangement shown in FIG. 3 outlined type shown with stabilizing rails RS arranged on the outer surfaces of both formwork slats as stabilizing elements. A rod-shaped connecting element in the example outlined, for example a threaded rod G, is guided at the locations of the markings M by the residual wall thickness of the formwork panels and otherwise through the longitudinal hole R of the spacer. The straightening rails RS have cutouts SL facing the formwork elements, through which the connecting element G projects. The elements are fixed in their relative position to one another by means of fixing elements such as a threaded nut GM or a wedge K and are preferably braced against one another by tensile loading of the connecting element G, which counteracts a pressure loading of the spacer .
Durch Erstreckung der Richtschienen über mehrere Schalungselemente wie in FIG. 8 angedeutet, in vertikaler Richtung vorzugsweise über eine gesamte Geschoßhöhe wird eine exakte Wandausrichtung gewährleistet. In einem derart stabilisierten Wandaufbau, wie ihn FIG. 9 im Wandquerschnitt mit durch Stützen S vertikal ausgerichteten richtschienen zeigt, wird beispielsweise Beton als Füllmaterial eingeschüttet.By extending the guide rails over several formwork elements as in FIG . 8 indicated, in the vertical direction, preferably over an entire floor height, an exact wall alignment is ensured. In such a stabilized wall structure as FIG. 9 shows in the wall cross section with vertical rails aligned by supports S, for example concrete is poured in as filler material.
Die Richtschienen zeigen, wie in FIG. 10 in schrägperspektivischer Darstellung skizziert, beispielsweise eine Reihe von Löchern in regelmäßigen Abständen entsprechend den Abständen der Längslöcher R bzw. Markierungen der K -The directional rails show, as shown in FIG. 10 outlined in an oblique perspective, for example a series of holes at regular intervals corresponding to the distances between the longitudinal holes R or markings of the K -
Schalungselemente Gleichwertige Anordnungen zu der regelmäßigen Lochreihe, wie z B sich über mehrere Lochabstande erstreckende Schlitze etc sind dem Fachmann geläufigFormwork elements Arrangements equivalent to the regular row of holes, such as slots extending over several hole distances, etc., are known to the person skilled in the art
Die sich über mehrere Schalungselemente erstreckenden Stabilisierungselemente wie z B Richtschienen sind nicht notwendigerweise an allen diesen Schalungselementen befestigt bzw verspannt Als Stabilisierungselemente kommen prinzipiell auch auf einzelne Schalungselemente beschrankte, horizontal oder diagonal angeordnete Schienen gekrümmte Schienen für spezielle Wandverlaufe etc in FrageThe stabilizing elements, such as straightening rails, which extend over several formwork elements, are not necessarily fastened or tensioned to all of these formwork elements. In principle, curved rails that are restricted to individual formwork elements, curved or diagonally arranged rails are also suitable for special wall profiles, etc.
Nach dem Ausharten des Fullmateπals können die Fixierungselemente GM,K gelost die Verbindungselemente G aus den Langslochem gezogen und die Stabilisierungselemente abgenommen werden Durch die Möglichkeit der einfachen Entfernung der Verbindungselemente weurden Warmebrucken, die durch verbleibende Verbindungselemente entstehen können, vermieden Darüber hinaus entfallenAfter the full material has hardened, the fixing elements GM, K can be loosened, the connecting elements G can be pulled out of the Langslochem, and the stabilizing elements can be removed. The possibility of simply removing the connecting elements avoids thermal bridging, which can arise from remaining connecting elements
Arbeitsschritte zum Abtrennen von überstehenden Teilen von Verbindungselementen und die Verbindungselemente können immer wieder verwandt werdenSteps for separating protruding parts of connecting elements and the connecting elements can be used again and again
Die nach Entfernen der Verbindungselemente verbleibenden Locher in den Außenflachen der Schalungselemente können mit Stopfen oder dergleichen verschlossen werden soweit nicht durch eine Beplankung, durch Verputz etc ohnehin eine Uberdeckung dieser Locher erfolgtThe holes remaining in the outer surfaces of the formwork elements after the connection elements have been removed can be closed with plugs or the like, provided that these holes are not covered anyway by planking, plastering, etc.
Zusatzlich zu der bevorzugten Ausfuhrungsform nach FIG 3 sind in den FIG 4 bis 7 weitere vorteilhafte Ausfuhrungsformen des erfindungsgemaßen Schalungselements ausschnittsweise skizziert Bei der Erläuterung der FIG 4 bis 7 werden im wesentlichen nur die Abweichungen gegenüber vorhergehenden Ausfuhrungsformen hervorgehoben und bezüglich übereinstimmenden Merkmalen wird auf vorangehende Darlegungen verwiesen Bei der Ausfuhrungsform nach FIG 4 ist bereits bei der Herstellung der Schalungspiatteπ in der Verlängerung der Langsachse L die Ausformung eines durchgehenden Loches PL durch die Plattenwandung berücksichtigt Dies ist insbesondere bei Plattenmateπalien von Vorteil, die nicht an einer Markierungssteile leicht durchstoßen oder aufgebohrt werden könnenIn addition to the preferred embodiment according to FIG. 3, further advantageous embodiments of the formwork element according to the invention are partially sketched in FIGS In the embodiment according to FIG. 4, the formation of a through hole PL through the plate wall is already taken into account in the manufacture of the formwork plate in the extension of the longitudinal axis L. This is particularly advantageous in the case of plate materials that cannot be easily pierced or drilled out on a marking part
Eine solche vorgeformte Öffnung PL in der Plattenwand ist auch bei der Ausfuhrungsform nach FIG 5 vorgesehen, bei welcher aber der Abstandshalter bereits bei der Herstellung der Schalungsplatte in diese mit eingeformt ist, z B durch Umschaumen, Umgießen oder dergleichen Das Schalungselement liegt dabei nach dem Herstellungsprozeß bereits als aus zwei Schalungsplatten und mehreren Abstandshaltern bestehendes Gebilde vorSuch a preformed opening PL in the panel wall is also provided in the embodiment according to FIG. 5, in which, however, the spacer is also molded into it during the manufacture of the formwork panel, for example by foaming, casting or the like. The formwork element lies after the manufacturing process already as a structure consisting of two formwork panels and several spacers
Die FIG 6 zeigt wie die FIG 5 einen Ausschnitt aus einer Schalungsplatte mit fest eingeformtem Abstandshalter, jedoch wie in FIG 3 ohne weiterführendes Wandungsloch In FIG 7 ist schließlich eine Ausfuhrung skizziert, bei der sich der fest eingeformte Abstandshalter in einem Fortsatz Z über die Endplatte hinaus bis zur Außenflache der Schalungsplatte als Verlängerung des rohrformigen Mittelteils erstreckt und so eine durchgehende Wandung des Langsloches bildetLike FIG. 5, FIG. 6 shows a section of a formwork panel with a rigidly molded-in spacer, but as in FIG. 3 without a further wall hole. Finally, FIG. 7 shows an embodiment in which the rigidly molded-in spacer extends in an extension Z beyond the end panel extends to the outer surface of the formwork panel as an extension of the tubular middle part and thus forms a continuous wall of the elongated hole
Die Erfindung ist nicht auf die beschriebenen Beispiele beshrankt, sondern im Rahmen fachmannischen Könnens in verschiedenen Ausfuhrungen realisierbar Insbesondere können die erhabenen und vertieften Rasterungen vertauscht oder zusätzliche Strukturen zur Abdichtung von Fugen zwischen aufeinandergesetzten Schalungselementen gegen das Austreten von Zementflussigkeit vorgesehen sein The invention is not limited to the examples described, but rather can be implemented in various designs within the scope of professional skill. In particular, the raised and recessed grids can be interchanged or additional structures can be provided for sealing joints between stacked formwork elements to prevent cement liquid from escaping
