A form (1) for ceiling edges including a supporting sleeve (5) which is adapted to be encased in concrete or sunk into the upper area of a wall (4) and serves to receive a tie (6) or the like for supporting a form panel (2) and/or a rail (3) holding the latter or a similar support for the front end of the ceiling (8), characterized in that the supporting sleeve (5) has a female thread fitting the male thread (10) of standard formwork tie rods, and that a formwork tie rod is provided as the tie (6).

Description

Die Erfindung betrifft eine Deckenrandschalung mit einer Haltehülse, welche in den oberen Bereich einer Wand einbetonierbar oder einsenkbar ist und zum Aufnehmen eines Ankers od.dg!. zum Abstützen einer Schaltafel und/oder einer diese haltenden Schiene od.dgl. Träger für die Stirnseite der Decke dient.The invention relates to a ceiling edge formwork with a holding sleeve which can be concreted or countersunk in the upper region of a wall and oddg for receiving an anchor !. for supporting a formwork panel and / or a rail or the like holding it. Carrier for the face of the ceiling is used.

Derartige Deckenrandschalungen sind bereits bekannt. Die DE-A-29 12 122, DE-U-81 33 870 und DE-U-82 13 932 zeigen solche Schalungen, deren einbetonierbare Haltehülsen hinter einer Einführöffnung eine Erweiterung haben, in der ein T-förmiger Anker durch Drehung fixiert werden kann.Such slab edge formwork are already known. DE-A-29 12 122, DE-U-81 33 870 and DE-U-82 13 932 show such formwork, the concreting holding sleeves behind an insertion opening have an extension in which a T-shaped anchor can be fixed by rotation .

Ferner ist aus der DE-A-30 08 473 bereits eine Deckenrandschalung bekannt, deren Haltehülse zusammen mit einem ihre lichte Weite durchsetzenden Stift und einer von diesem Stift an einem Glied gehaltenen Kette oder Öse einbetoniert werden kann. An der Kette kann wiederum eine äußere Schiene od. dgl. Träger beispielsweise mit einem Keil gehalten werden, wobei dann die Kette die erforderlichen Zugkräfte über den erwähnten Stift auf die Haltehülse übertragen kann.Furthermore, from DE-A-30 08 473 a slab edge formwork is already known, the holding sleeve can be concreted in together with a pin penetrating its clear width and a chain or eyelet held by this pin on a link. An outer rail or similar carrier can in turn be held on the chain, for example with a wedge, the chain then being able to transmit the required tensile forces to the holding sleeve via the aforementioned pin.

All diese vorbekannten Haltehülsen haben eine aufwendige Form und vor allem benötigt der mit ihnen zusammenwirkende Anker eine ganz spezielle Ausgestaltung insbesondere an seinem mit der Haltehülse zusammenwirkenden Verankerungsende.All of these known holding sleeves have an elaborate shape and, above all, the anchor cooperating with them requires a very special configuration, in particular at its anchoring end interacting with the holding sleeve.

Aus der Literaturstelle "Betomax Kunststoff-und Metallwarenfabrik GmbH & Co.KG, Neuss, Katalog Juli 1981, deutsche Ausgabe, S.27 u.28 sowie ferner aus DE-C-1 921 327 und DE-B-20 12 556 sind Schalungen für Beton-Gesimskappen, Fahrbahnränder oder ähnliche Bereiche an Fahrbahnplatten von Brücken bekannt, bei denen gleichzeitig begehbare Konsolen verankert werden sollen. Um die Konsole anhängen zu können, werden an der Unterseite der zu betonierenden Simse und Ränder mit einem Innengewinde versehene Hülsen einbetoniert, in die nach unten ragende Gewindestangen eingeschraubt werden können, welche ihrerseits Träger zum Verankern der Konsole tragen können.From the literature "Betomax Kunststoff- und Metallwarenfabrik GmbH & Co.KG, Neuss, catalog July 1981, German edition, pp. 27 and 28 as well as from DE-C-1 921 327 and DE-B-20 12 556 are formwork Known for concrete cornice caps, road edges or similar areas on road slabs of bridges, in which walk-on brackets are to be anchored at the same time downwardly projecting threaded rods can be screwed in, which in turn can carry beams for anchoring the console.

Während also bei den reinen Deckenschalungen jeweils Haltehülsen mit inneren Vorsprüngen unterschiedlicher Gestaltung und darauf abgestimmten Ankern bekannt sind, ist es gleichzeitig bekannt, für die Aufnahme größerer Belastungen und die Erzeugung einer größeren Sicherheit im Bereich begehbarer Konsolen diese mittels Innengewinde-Hülsen an betonierten Elementen zu verankern. Bei Deckenrandschalungen treten jedoch in aller Regel aufgrund der geringen Schütthöhe des Betons keine sehr großen Kräfte auf, so daß die bisher bekannten vorerwähnten Haltehülsen für diesen Anwendungszweck genügen. Dabei ist es notwendig, jeweils auf die Haltehülsen abgestimmte Anker vorrätig zu haben.While holding sleeves with inner protrusions of different designs and matching anchors are known for the pure slab formwork, it is also known to anchor them to concrete elements by means of internally threaded sleeves in order to absorb greater loads and create greater safety in the area of walkable brackets . With slab edge formwork, however, generally no very large forces occur due to the low pouring height of the concrete, so that the previously mentioned holding sleeves are sufficient for this application. It is necessary to have anchors matched to the holding sleeves.

Der Erfindung liegt die Aufgabe zugrunde, eine Deckenrandschalung der eingangs erwähnten Art zu schaffen, die die Verwendung bereits vorhandener Anker erlaubt, so daß die Fertigung eines speziellen Ankers, sei es ein T-förmiger Anker, sei es eine Kette oder ein sonstiges Spezialteil zur Anpassung an die Haltehülse entfällt und die Lagerhaltung vereinfacht ist.The invention has for its object to provide a ceiling formwork of the type mentioned, which allows the use of existing anchors, so that the production of a special anchor, be it a T-shaped anchor, be it a chain or other special part for adaptation to the holding sleeve and the storage is simplified.

Die Lösung dieser Aufgabe besteht darin, daß die Haltehülse ein Innengewinde aufweist, welches zu dem Außengewinde handelsüblicher Schalungszuganker paßt und daß als Anker ein Schalungszuganker vorgesehen ist.The solution to this problem is that the holding sleeve has an internal thread which fits the external thread of commercially available formwork tie rods and that a formwork tie rod is provided as the anchor.

Dadurch ist es möglich, einen bereits in aller Regel auf Lager befindlichen Schalungszuganker beliebiger Länge zu verwenden, um die Deckenrandschalung an der erfindungsgemäßen Haltehülse zu verankern. Ein weiterer Vorteil besteht darin, daß kein Keil od.dgl. für die Befestigung der Schiene oder eines Trägers benötigt wird, sondern daß eine ebenfalls vorhandene Mutter des Schalungszugankers als Gegenverankerung benutzt werden kann. Zum Fixieren einer Deckenrandschalung wird also als spezielles Teil nur noch die erfindungsgemäße Haltehülse benötigt, während alle übrigen Teile bei Baufirmen, die mit Schalungen arbeiten, schon vorhanden sind und von diesen Schalungen übernommen werden können. Zwar treten bei solchen Deckenrandschalungen keine so hohen Kräfte auf, daß die Haltehülse dazu das Innengewinde benötigen würde, jedoch erlaubt die so gestaltete Haltehülse in vorteilhafter Weise die Verwendung schon vorhandener Schalungszuganker, so daß insgesamt der Aufwand bei einer solchen Deckenrandschalung vermindert ist.This makes it possible to use a formwork tie rod of any length that is usually already in stock in order to anchor the slab edge formwork to the holding sleeve according to the invention. Another advantage is that no wedge or the like. is required for fastening the rail or a beam, but that an existing nut of the formwork tie rod can be used as a counter anchor. To fix a ceiling edge formwork, only the holding sleeve according to the invention is required as a special part, while all other parts are already available at construction companies that work with formwork and can be taken over by these formworks. Although no such high forces occur in such slab edge formwork that the holding sleeve would require the internal thread for this purpose, the holding sleeve designed in this way advantageously allows the use of existing formwork tie rods, so that overall the effort involved in such slab edge formwork is reduced.

Besonders zweckmäßig ist es, wenn die Haltehülse aus Kunststoff besteht. Sie ist so mit ihrem Innengewinde einfach herstellbar und kann den noch genügend hohe Zugkräfte aufnehmen, um die relativ geringen Betonierdrücke einer Deckenstirnschalung aufzufangen.It is particularly expedient if the holding sleeve consists of plastic. It is so easy to manufacture with its internal thread and can absorb the high enough pulling forces to absorb the relatively low concreting pressures of a formwork for the ceiling.

Zweckmäßig ist es, wenn an dem der Deckenstirnschalung zugewandten Rand der Haltehülse wenigstens zwei Laschen od. dgl. mit Nagel- oder Schraubenlöchern versehen sind. Die Fertigung aus Kunststoff erlaubt dabei die Anbringung dieser Löcher erst durch das Einschlagen der Nägel oder das Eindrehen der Schrauben. Wird die Deckenstirnschalung entfernt, bleibt die Hülse im Beton und die Nägel reißen einfach aus der Schalung heraus. Vor dem Betonieren ist jedoch die Haltehülse zunächst an der Schalung sicher befestigt, ohne durch den einzugießenden Beton aus ihrer Lage verschoben werden zu können.It is expedient if at least two tabs or the like are provided with nail or screw holes on the edge of the holding sleeve facing the ceiling face formwork. The production from plastic allows these holes to be made only by driving in the nails or screwing in the screws. If the slab formwork is removed, the sleeve remains in the concrete and the nails simply tear out of the formwork. Before concreting, however, the holding sleeve is first securely fastened to the formwork without being able to be moved out of its position by the concrete to be poured.

Um genügend hohen Widerstand gegen die von dem Anker aufgebrachten Zugkräfte mit der erfindungsgemäßen Haltehülse übertragen zu können, kann die Haltenhülse inbesondere an ihrem ihrem Rand entgegengesetzten inneren Ende Vorsprünge, z. B. ebenfalls zwei einander gegenüberliegende Laschen, einen umlaufenden Bund oder eine gewellte Außenseite haben. Die Fertigung aus Kunststoff erlaubt dabei beliebige Formen und Größen, so daß eine Anpassung an die zu erwartenden Kräfte auf einfache Weise möglich ist. Dabei können zwischen dem Hülsenkörper und diesen Vorsprüngen Verstärkungsrippen angeordnet sein, was wiederum durch die Fertigung aus Kunststoff besonders einfach realisiert werden kann.In order to be able to transmit sufficiently high resistance to the tensile forces exerted by the anchor with the holding sleeve according to the invention, the holding sleeve can in particular have projections, for. B. also two each other have opposite tabs, a circumferential collar or a corrugated outside. The production from plastic allows any shape and size, so that an adaptation to the expected forces is possible in a simple manner. Reinforcing ribs can be arranged between the sleeve body and these projections, which in turn can be realized particularly easily by the production from plastic.

Der Haltehülse kann ein Verschluß zugehören, der nach dem Ausschalen und Entfernen der Ankerstange auf die Hülsenöffnung gedrückt und/oder in die Haltehülse geschraubt werden kann. Dadurch ergibt sich ein glatter Abschluß der Wand, der dann später z. B. mittels Putz od. dgl. gut abgedeckt werden kann.The holding sleeve can include a closure which, after stripping and removing the anchor rod, can be pressed onto the sleeve opening and / or screwed into the holding sleeve. This results in a smooth finish of the wall, which is then later z. B. can be covered by plaster or the like.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen ergibt sich eine einfach und preiswert herstellbare Haltehülse, die mit schon vorhandenen Schalungszugankern zusammen bereits eine Deckenrandschalung halten kann, so daß die Lagerhaltung vereinfacht ist. Aufwendige Spezial-Anker werden vermieden.Especially when combining one or more of the features and measures described above results in a simple and inexpensive to produce holding sleeve that can already hold a ceiling edge formwork together with existing formwork tie rods, so that the storage is simplified. Elaborate special anchors are avoided.

Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten anhand der Zeichnung noch näher beschrieben. Es zeigt:

  • Fig. 1 eine Seitenansicht und
  • Fig. 2 eine Stirnansicht einer erfindungsgemäßen Haltehülse sowie
  • Fig. 3 einen Schnitt durch eine Wand und eine darauf aufbetonierte Decke mit Deckenstirnschalung, welche mit einem Schalungszuganker und der erfindungsgemäßen Haltehülse fixiert ist.
The invention is described in more detail below with its details that are essential to it, using the drawing. It shows:
  • Fig. 1 is a side view and
  • Fig. 2 is an end view of a holding sleeve according to the invention and
  • Fig. 3 shows a section through a wall and a concrete slab concreted thereon with slab formwork, which is fixed with a formwork tie rod and the holding sleeve according to the invention.

Zum Befestigen einer Deckenrandschalung 1, welche in der Regel aus einer Schaltafel 2 und einer diese abstützenden Schiene 3 od. dgl. Träger besteht, dient eine in eine bereits erstellte Wand 4 eingelassene Haltehülse 5, ein damit zusammenwerkender Anker 6 und ein die Schiene 3 übergreifendes Befestigungselement 7. Auf diese Weise kann eine Schaltafel 2 im oberen Randbereich einer Wand 4 so befestigt werden, daß auf diese Wand 4 eine Decke 8 aufbetoniert werden kann.For fastening a ceiling edge formwork 1, which generally consists of a formwork panel 2 and a rail 3 or the like supporting it, a holding sleeve 5 is inserted into a wall 4 that has already been created, an anchor 6 cooperating therewith, and an overlapping rail 3 Fastening element 7. In this way, a formwork panel 2 can be fastened in the upper edge region of a wall 4 in such a way that a ceiling 8 can be concreted onto this wall 4.

Die Haltehülse 5 hat ein Innengewinde 9, welches zu dem Außengewinde 10 eines handelsüblichen Schalungszugankers paßt, der somit als Ankerstange 6 mit dieser Haltehülse 5 zusammenwirken kann. Ferner paßt dann zu der gesamten Anordnung auch als Befestigungselement 7 eine handelsübliche, bei den meisten derartigen Schalungen bereits vorhandene Mutter. Dabei kann die Ankerstange 6 einfach in die Haltehülse 5 eingeschraubt werden, wonach die Schaltafel 2 angelegt und mit einer über den Anker 6 geschobenen Schiene 3 sowie der Mutter 7 fixiert werden kann. Dabei kann der Anker 6 sogar beliebig weit vorstehen, obwohl selbstverständlich in der Regel ein kurzer Schalungszuganker ausreichen wird. Ein Spezialanker wird nicht benötigt.The holding sleeve 5 has an internal thread 9, which fits the external thread 10 of a commercially available formwork tie rod, which can thus cooperate with this holding sleeve 5 as an anchor rod 6. Furthermore, a commercially available nut, which is already present in most such formwork, then also fits as a fastening element 7 to the entire arrangement. The anchor rod 6 can simply be screwed into the holding sleeve 5, after which the panel 2 can be placed and fixed with a rail 3 pushed over the anchor 6 and the nut 7. The anchor 6 can even protrude as far as desired, although of course a short formwork tie rod will usually suffice. A special anchor is not required.

Die Haltehülse 5 besteht zweckmäßigerweise aus Kunststoff, so daß sie zusammen mit ihrem Gewinde in einem Arbeitsgang gefertigt werden kann. Aufgrund der Gewindegröße ist sie dennoch in der Lage, die Zugkräfte aufzunehmen, die aus den relativ geringen Betonierdrücken einer Deckenstirnschalung 1 resultieren.The holding sleeve 5 is expediently made of plastic, so that it can be manufactured together with its thread in one operation. Due to the thread size, it is nevertheless able to absorb the tensile forces that result from the relatively low concreting pressures of a formwork 1.

An dem der Deckenstirnschalung 1 zugewandten Rand 11 der Haltehülse 5 erkennt man zwei Laschen 12 mit Nagellöchern 13, womit die Haltehülse 5 an der Innenseite der Schalung der Wand 4 vor deren Betonieren befestigt werden kann, um in die Wand 4 einbetoniert zu werden.On the edge 11 of the holding sleeve 5 facing the ceiling face formwork 1, two tabs 12 with nail holes 13 can be seen, with which the holding sleeve 5 can be fastened to the inside of the formwork of the wall 4 before it is concreted, in order to be concreted into the wall 4.

An dem dem Rand 11 entgegengesetzten Ende 14 sind Vorsprünge, im Ausführungsbeispiel wiederum zwei Laschen 15 an der Haltehülse 5 vorgesehen, um deren Widerstand gegen die Zugkräfte der Ankerstange 6 zu erhöhen. Dabei erkennt man zwischen dem Hülsenkörper selbst und diesen Laschen 15 Verstärkungsrippen 16. All diese Formgebungen sind deshalb auf einfache Weise und preiswert herstellbar, weil die gesamte Haltehülse 5 einstückig aus Kunststoff gefertigt werden kann. auch könnte die Außenseite der Hülse 5 umlaufende im Querschnitt wellenförmige Profilierungen haben.At the end 14 opposite the edge 11, projections, in the exemplary embodiment again two tabs 15 are provided on the holding sleeve 5 in order to increase their resistance to the tensile forces of the anchor rod 6. It can be seen between the sleeve body itself and these tabs 15 reinforcing ribs 16. All these shapes can be produced easily and inexpensively because the entire holding sleeve 5 can be made in one piece from plastic. the outside of the sleeve 5 could also have circumferential profiles with a wavy cross section.

Nach Abschluß der Betonierarbeiten für die Decke 8 und nach dem Ausschalen kann in die vordere Hülsenöffnung ein nicht näher dargestellter Verschluß eingedrückt oder auch eingeschraubt werden, um einen glatten Abschluß der Wand 4 auch im Bereich dieser Haltehülse 5 zu erzielen.After completion of the concreting work for the ceiling 8 and after stripping, a closure, not shown, can be pressed or screwed into the front sleeve opening in order to achieve a smooth closure of the wall 4 also in the area of this holding sleeve 5.
