Description

Die Erfindung bezieht sich auf eineThe invention relates to a

Haltevorrichtung für senkrecht angeordnete Schalbretter bei Deckenbetonierungen gemäß dem Oberbegriff des Hauptanspruches.Holding device for vertically arranged formwork boards for ceiling concreting according to the preamble of the main claim.

Eine gattungsbildende Haltevorrichtung ist aus dem DE-U-1 814 213 bekannt. Diese Haltevorrichtung ist mehrteilig ausgebildet und muß in die letzte Steinlage eingesetzt werden, wobei der Schalbrettflansch so hoch sein muß, daß er von der Unterseite der letzten Steinlage bis zur Oberkante der Betonierschicht reicht. Um ein Abbiegen des Schalbrettflansches zu vermeiden, muß dieser verformungssteif und stabil ausgebildet sein. Nach Entfernen der Haltevorrichtung ist ein neues Verfugen der letzten Steinlage erforderlich. Der Einsatz unterschiedlicher Schalbretter ist nur in begrenztem Umfang möglich, da der Stützflansch die Höhe des Schalbrettes begrenzt.A generic holding device is known from DE-U-1 814 213. This holding device is constructed in several parts and must be inserted into the last stone layer, the formwork flange being so high that it extends from the underside of the last stone layer to the upper edge of the concreting layer. In order to prevent the formwork flange from bending, it must be rigid and stable. After removing the holding device, new grouting of the last stone layer is required. The use of different formwork boards is only possible to a limited extent because the support flange limits the height of the formwork board.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsbildende Haltevorrichtung dahingehend zu verbessern, daß sie einteilig und kostengünstiger erstellt werden kann, deckengleich eingesetzt werden kann und keinerlei Beschränkungen für die Höhe der eingesetzten Schalbretter darstellt.The invention has for its object to improve the generic holding device in such a way that it can be created in one piece and more cost-effectively, can be used with the same ceiling and does not represent any restrictions on the height of the formwork boards used.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Hauptanspruches gelöst.This object on which the invention is based is achieved by the features of the characterizing part of the main claim.

Mit anderen Worten ausgedrückt, wird ein stufenförmiger Haltebügel eingesetzt, der auf die Oberseite des Mauerwerkes mit einem Stützflansch aufsetzbar ist und dessen nach oben gerichteter Schalbrettflansch an der Innenseite des Schalbrettes befestigbar ist. Hierdurch ist das Schalbrett gegenüber der Oberkante des Mauerwerkes beliebig hin- und herverschiebbar und kann damit auf eine genau bestimmte Höhe der zu betonierenden Decke eingestellt werden, wobei die Breitre des Schalbrettes weder von der Konstruktion der Haltevorrichtung noch von der Stärke der betonierenden Decke abhängig ist.In other words, a step-shaped retaining bracket is used, which can be placed on the top of the masonry with a support flange and whose upwardly facing formwork panel flange can be attached to the inside of the formwork board. As a result, the formwork board can be moved back and forth as desired relative to the top edge of the masonry and can thus be set to a precisely defined height of the ceiling to be concreted, the width of the formwork board not depending on the construction of the holding device or on the thickness of the concreting ceiling.

Die Befestigung der Schalbretter an dem Schalbrettflansch kann durch Nageln erfolgen, was den Vorteil hat, daß durch Verwendung von Nägeln, die eine größere Länge als die Schalbrettstärke haben, diese außen umgebogen werden können und dadurch ein Widerlager für den beim Betonieren auftretenden Druck schaffen oder die äußere Seite des Schalbrettflansches ist mit Befestigungsmitteln, die tannenzapfartig ausgebildet sind, versehen.The formwork boards can be attached to the formwork flange by nailing, which has the advantage that by using nails that are longer than the formwork thickness, these can be bent outside and thereby create an abutment for the pressure that occurs during concreting or the The outer side of the shuttering board flange is provided with fastening means which are designed like a pine cone.

Aus der US-A-2 340 439 ist eine Betonverschalung bekannt, bei welcher winkelförmige Träger eingesetzt werden, die zur Aufnahme eines Querbalkens dienen, der über die gesamte Länge der einzelnen Schalbretter reicht und diese festlegen soll. In dieser Literaturstelle wird weder die Aufgabe noch die Lösung der der Erfindung zugrundeliegenden Aufgabe beschrieben.From US-A-2 340 439 a concrete formwork is known, in which angular girders are used which serve to receive a crossbeam which extends over the entire length of the individual formwork boards and is intended to fix them. In this reference, neither the object nor the solution of the object on which the invention is based is described.

Aus der FR-A-2 354 433 ist eine Haltevorrichtung für Schalbretter bei Deckenbetonierungen bekannt, die, wenn das Schalbrett eine beliebige Höhe aufweisen soll, das Mauerwerk durchquert und als Klemmbügel ausgebildet ist. Hier ist es erforderlich, nachträglich das in der Mauer gebildete Loch neu zu verfugen.From FR-A-2 354 433 a holding device for formwork boards for ceiling concreting is known which, if the formwork board should have any height, traverses the masonry and is designed as a clamping bracket. Here it is necessary to re-grout the hole formed in the wall.

Schließlich ist es aus der CH-A-625 589 bekannt, einen einfach winkelförmigen Bügel einzusetzen, der sich aber nicht an der Innenseite des Mauerwerks abstützt und hier befestigt werden kann, sondern er stützt sich auf der Verschalung für die zu gießende Decke ab und muß, wenn er die ausreichende Tragfähigkeit besitzen soll, hier besonders verschraubt werden, so daß danach das Entfernen der Deckenverschalung schwierig ist und die Schrauben weiterhin sichtbar bleiben.Finally, it is known from CH-A-625 589 to use a simple angular bracket which, however, is not supported on the inside of the masonry and can be fastened here, but is supported on the formwork for the ceiling to be cast and must , if it should have sufficient load-bearing capacity, be screwed here so that it is difficult to remove the ceiling formwork and the screws remain visible.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei in

  • Fig. 1 schaubildlich den Einsatz des
  • Haltebügels und in Fig. 2 in größerem Maßstab den eigentlichen Haltebügel.
An embodiment of the invention is explained below with reference to the drawings. The drawings show in
  • Fig. 1 shows the use of the
  • Retaining bracket and in Fig. 2 on a larger scale the actual bracket.

In Fig. 1 ist ein Teil eines Mauerwerkes 1 mit Schalbrettern 2 für die Unterseite der einzubringenden Betondecke, ein seitliches Schalbrett 3 und ein Haltebügel 4 dargestellt, der sich auf die Oberkante des Mauerwerks 1 auflegt und im wesentlichen stufenförmig ausgebildet ist.In Fig. 1, part of a masonry 1 with shuttering boards 2 for the underside of the concrete ceiling to be introduced, a side shuttering board 3 and a bracket 4 is shown, which lies on the upper edge of the masonry 1 and is essentially step-shaped.

Die Ausbildung des Haltebügels 4 geht deutlicher aus Fig. 2 hervor. Mit 5 ist ein Stützflansch des Haltebügels 4 bezeichnet, mit 6 ein Schalbrettflansch und mit 7 ein Mauerflansch, wobei der Schalbrettflansch 6 und der Mauerflansch 7 sich rechtwinklig zur Ebene des Stützflansches 5 erstrecken.The design of the bracket 4 is clearer from Fig. 2. With 5 a support flange of the bracket 4 is designated, with 6 a formwork flange and with 7 a wall flange, the formwork flange 6 and the wall flange 7 extending at right angles to the level of the support flange 5.

Sowohl im Schalbrettflansch 6 wie auch im Mauerflansch 7 sind Bohrungen 8 bzw. 9 vorgesehen, die der Festlegung einerseits des eigentlichen Haltebügels 4 an der Innenseite der Mauer 1 dienen, zum andern zur Festlegung des Schalbrettes 3 an der Außenseite des Schalbrettflansches 6.Both in the formwork flange 6 and in the wall flange 7, holes 8 and 9 are provided, which serve to fix the actual retaining bracket 4 on the inside of the wall 1 on the one hand, and to fix the formwork board 3 on the outside of the formwork flange 6 on the other.

Bei 8 ist eine im Übergangsbereich zwischen dem Stützflansch 5 und dem Mauerflansch 7 vorgesehene Sollbruchlinie dargestellt, die durch einfache Bohrungen gebildet sein kann, so daß es möglich ist, nach Fertigstellung der Decke diesen Mauerflansch 7 vom restlichen Teil des Haltebügels 4 abzubrechen. Der Haltebügel 4 verbleibt dann mit seinem Stützflansch 5 und mit dem Schalbrettflansch 6 in dem eingebrachten Beton. Das Entfernen der Schalbretter 3 vom Schalbrettflansch 6 erfolgt durch einfaches Abbiegen des Schalbrettes 3 von dem Schalbrettflansch 6.At 8, a predetermined breaking line is shown in the transition region between the support flange 5 and the wall flange 7, which can be formed by simple bores, so that it is possible to break off this wall flange 7 from the remaining part of the bracket 4 after completion of the ceiling. The bracket 4 then remains with its support flange 5 and with the formwork flange 6 in the introduced concrete. The shuttering boards 3 are removed from the shuttering board flange 6 by simply bending the shuttering board 3 from the shuttering board flange 6.

Insbesondere aus Fig. 1 ist erkennbar, daß durch Verwendung des Haltebügels 3 die Höhe des eigentlichen Schalbrettes 3 unbedeutend ist und trotzdem eine exakte Betonierhöhe erreicht wird. Dieser Erfolg wird dadurch erreicht, daß das Schalbrett 3 an der Außenseite der Mauer beliebig hoch verschoben werden kann und, wenn die gewünschte Höhe erreicht ist, an dem Haltebügel 4 befestigt werden kann.From Fig. 1 in particular it can be seen that the height of the actual shuttering board 3 is insignificant and the exact concreting height is nevertheless achieved by using the holding bracket 3. This success is achieved in that the formwork board 3 can be moved to any height on the outside of the wall and, when the desired height is reached, can be attached to the bracket 4.

Die Breite des Stützflansches 5 richtet sich nach den üblichen Mauerwerksbreiten, die genormt sind, so daß nur eine begrenzte Anzahl von unterschiedlich ausgebildeten Haltebügeln 4 vorrätig gehalten werden muß.The width of the support flange 5 depends on the usual masonry widths, which are standardized, so that only a limited number of differently designed brackets 4 must be kept in stock.

Der eigentliche Haltebügel besteht vorzugsweise aus verzinktem Metall, kann aber in gleicher Weise auch aus Kunststoff gefertigt werden.The actual bracket is preferably made of galvanized metal, but can also be made of plastic in the same way.

Die Außenseite des Schalbrettflansches 6 kann mit tannenzapfartigen, fest angeordneten Zapfenverbindungen ausgerüstet sein, die in das Schalbrett 3 eingeschlagen werden können, so daß dadurch die Benutzung zusätzlicher Nägel od. dgl. vermieden wird. Es ist auch möglich, daß die Schalbretter 3 mit U-förmigen Haltebügeln ausgerüstet sind, die über den Schalbrettflansch 6 geschoben werden können.The outside of the shuttering board flange 6 can be equipped with pine cone-like, fixed pin connections which can be hammered into the shuttering board 3, so that the use of additional nails or the like is thereby avoided. It is also possible that the formwork boards 3 are equipped with U-shaped holding brackets which can be pushed over the formwork board flange 6.
