Abstract

1. Strut for floor shutterings having a head piece serving as a support for the corners of four mutually abutting shuttering panels. 2.1 In a known strut of this type, it is necessary for the strut to be installed in a specific position, so that projections engage in recesses in the shuttering panels to form a lift-off catch. A strut of this type is therefore also not suitable for installation of the shuttering panels from above. The new strut, in contrast, permits installation in any of four possible positions of the head piece and also erection of the shuttering from above. 2.2 The base plate of the head piece is, in plan view, square in shape and has, on the head piece, projections and webs alternately offset by in each case 45 DEG , in each case in a square arrangement. 2.3 This strut simplifies installation and holds the shuttering panels, placed on it, together exactly, irrespective of whether the shuttering is erected from below or from above. A lift-off catch has proved superfluous. <IMAGE>

Description

Die Erfindung betrifft eine Stütze für Deckenschalungen, die aus einer Mehrzahl von an ihren Ecken aneinanderstoßend zusammengesetzten, jeweils einen aus Längsholmen und Querholmen gebildeten Rahmen aufweisenden rechteckigen Schaltafeln bestehen, wobei diese Stütze mit einem als Auflager für die Ecken von vier aufeinanderstoßenden Schaltafeln dienen­den Kopfstück versehen ist, das eine horizontale Grundplatte und vier auf dieser in etwa quadratischer Anordnung vorgesehene hochstehende Vorsprünge, die jeweils in den Eckbereich des Rahmens einer abzustützenden Schaltafel eingreifen können, sowie hochstehende Stege, welche zwischen die Rahmen benachbarter Schaltafeln ragen können, aufweist.The invention relates to a support for slab formwork which consists of a plurality of rectangular formwork panels assembled together at their corners, each having a frame formed from longitudinal spars and transverse spars, this support being provided with a head piece serving as a support for the corners of four abutting formwork panels , which has a horizontal base plate and four upright projections provided on this in an approximately square arrangement, each of which can engage in the corner region of the frame of a formwork panel to be supported, as well as upstanding webs which can protrude between the frames of adjacent formwork panels.

Bei einer bekannten Stütze dieser Art (EP 0 130 425 A 2) sind auf der Grundplatte des Kopfstückes zwei verschiedene Arten von hochstehenden Stegen angeordnet, wobei die eine Art dieser Stege einen erweiterten Kopf aufweist, der in Öffnungen der Rahmen benachbarter Schaltafeln eingreifen soll, um eine Abhebesicherung zu bilden. Wegen dieser Abhebe­sicherung ist es erforderlich, die Stütze in besonderer Position einzu­bauen und die Schaltafeln beim Einbau zu kippen, so daß ein Einbau nur von unten möglich ist. Insbesondere bei größeren Deckenhöhen ist aber ein Einbau von oben erwünscht. Außerdem ist bei diesen vorbekannten Stützen die jeweils richtige Anordnung der Stütze zu beachten, was eine gewisse Sorgfalt voraussetzt.In a known support of this type (EP 0 130 425 A 2), two different types of upstanding webs are arranged on the base plate of the head piece, one type of these webs having an expanded head which is intended to engage in openings in the frames of adjacent formwork panels to form an anti-lift device. Because of this lift-off protection, it is necessary to install the support in a special position and to tilt the formwork panels during installation, so that installation is only possible from below. In particular with larger ceiling heights, installation from above is desirable. In addition, the correct arrangement of the support must be observed in each of these known supports, which requires a certain degree of care.

Der Erfindung liegt die Aufgabe zugrunde, die aus der EP 0 130 425 A 2 bekannte Stütze für Deckenschalungen derart zu verbessern, daß eine einfachere Handhabung der Stütze und auch eine Montage der Schalungs­platten der Deckenschalung von oben möglich ist.The object of the invention is to improve the support for slab formwork known from EP 0 130 425 A 2 in such a way that easier handling of the support and also assembly of the formwork panels of the slab formwork is possible from above.

Diese Aufgabe wird bei einer Stütze der eingangs genannten Gattung er­findungsgemäß dadurch gelöst, daß die Grundplatte der Stütze im Grundriß quadratisch ausgebildet ist und an dieser um jeweils 45° versetzt ab­wechselnd Vorsprünge und Stege in quadratischer Anordnung vorgesehen sind.This object is achieved according to the invention in a support of the type mentioned at the outset in that the base plate of the support is square in plan and there are alternately projections and webs offset by 45 ° in a square arrangement.

Bei der erfindungsgemäßen Stütze ist das Kopfstück also symmetrisch ausgebildet, so daß die Stütze in beliebiger Position eingebaut werden kann, d.h. die Bedienungsperson braucht nicht auf die winkelmäßige Lage des Kopfstückes der Stütze zu achten, die von unten schwer zu erkennen ist, so daß der Einbau erleichtert wird. Da eine Abhebesicherung ganz entfallen ist, können die Schaltafeln der Deckenschalung auch von oben auf die bereits aufgerichtete Stütze aufgelegt werden, ohne sie dabei kippen oder verkanten zu müssen. Ein falscher Einbau ist wegen der symme­trischen Ausbildung des Kopfstückes der Stütze nicht möglich, was insbe­sondere auch beim Einschalen größerer Höhen von Interesse ist.In the support according to the invention, the head piece is thus symmetrical, so that the support can be installed in any position, i.e. the operator need not pay attention to the angular position of the head piece of the support, which is difficult to see from below, so that the installation is facilitated. Since there is no need for a safety catch, the formwork panels of the slab formwork can also be placed on the already erected support from above without having to tilt or tilt them. Incorrect installation is not possible due to the symmetrical design of the head piece of the support, which is of particular interest when formwork is used at greater heights.

Obwohl bei der erfindungsgemäßen Stütze wegen der symmetrischen Ausbil­dung des Kopfstückes derselben nicht auf eine bestimmte Winkelposition des Kopfstückes geachtet zu werden braucht, kann man diese Stütze in gleicher Weise einbauen und auch wieder ausbauen wie die aus der EP 0 130 425 A 2 bekannte Stütze. Zusätzlich ist aber auch der Einbau der Schalungstafeln von oben möglich. Somit ergibt sich eine vielseitigere Anwendbarkeit bei einfacherer Handhabung.Although in the support according to the invention it is not necessary to pay attention to a specific angular position of the headpiece because of the symmetrical design of the headpiece thereof, this support can be installed and removed in the same way as the support known from EP 0 130 425 A 2. In addition, the formwork panels can also be installed from above. This results in a more versatile application with easier handling.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Stütze für Deckenschalungen dargestellt, und zwar zeigt

  • Fig. 1 eine Seitenansicht des am oberen Ende der Stütze anzubringenden Kopfstückes und
  • Fig. 2 eine Draufsicht auf das Kopfstück von oben.
In the drawing, an embodiment of the prop for slab formwork according to the invention is shown, namely shows
  • Fig. 1 is a side view of the head piece to be attached to the upper end of the support and
  • Fig. 2 is a plan view of the head piece from above.

Das Kopfstück (1) hat eine beispielsweise in Gußeisen erstellte Grundplatte (2), an deren Unterseite eine zylindrische Buchse (3) angeformt ist, in der ein Rohrstutzen (4) steckt, der in der Buchse (3) befestigt ist und mit seinem aus dieser herausragenden Ende in das obere Ende der nicht dargestellten Stütze eingesteckt werden kann. Ein radial verlaufen­des Loch (5) dient zur Aufnahme eines ebenfalls nicht dargestellten Verriegelungsbolzens.The head piece (1) has a base plate (2) made, for example, in cast iron, on the underside of which a cylindrical bush (3) is formed, in which a pipe socket (4) is inserted, which is fastened in the bush (3) and with it this protruding end can be inserted into the upper end of the support, not shown. A radial hole (5) serves to receive a locking bolt, also not shown.

An den vier Ecken der in Draufsicht quadratischen Grundplatte (2) sind nach auswärts verlaufende Tragarme (6) vorgesehen , die von der zylin­drischen Buchse (3) ausgehen und im Bereich außerhalb der Grundplatte (2) jeweils mit einem horizontalen plattenförmigen Auflager (7) versehen sind. Auf jedem Auflager (7) befindet sich ein hochstehender zylindrischer Bolzen (8), der am äußeren Ende (9) kegelstumpfförmig verjüngt ist. Diese Bolzen (8) ragen in der Montageposition der Stütze in den Eckbereich jeweils einer aufgesetzten Schaltafel innerhalb des äußeren Rahmens derselben.At the four corners of the base plate (2), which is square in plan view, support arms (6) extending outward are provided, which extend from the cylindrical bushing (3) and each have a horizontal plate-shaped support (7) in the area outside the base plate (2) are. On each support (7) there is an upstanding cylindrical bolt (8) which is tapered in the shape of a truncated cone at the outer end (9). These bolts (8) protrude in the assembly position of the support in the corner area of an attached panel within the outer frame of the same.

An den Längskanten der Grundplatte (2) sind im mittleren Bereich vier weitere Tragarme (10) angeordnet, die ebenfalls von der zylindrischen Buchse (3) ausgehen und sich wie die Tragarme (6) radial zu dieser Buchse erstrecken. Auf dem über die Grundplatte (2) hinausragenden Ende dieses Tragarmes (10) ist ein hochstehender zungenartiger Steg (11) vorgesehen, der beim dargestellten Ausführungsbeispiel mit dem Tragarm (10) aus einem Stück besteht. Am oberen Ende weist jeder Steg (11) abgekantete Ecken (12) auf.Four further support arms (10) are arranged on the longitudinal edges of the base plate (2) in the central area, which also extend from the cylindrical bushing (3) and, like the support arms (6), extend radially to this bushing. On the end of this support arm (10) projecting beyond the base plate (2) there is a raised tongue-like web (11) which, in the exemplary embodiment shown, consists of the piece with the support arm (10). At the upper end, each web (11) has folded corners (12).

Die Stege (11) legen sich bei der Montage einer Deckenschalung zwischen jeweils zwei benachbarte Schaltafeln außerhalb der Rahmen der Schaltafeln und bilden somit eine Begrenzungsanschlag für die Schaltafeln. Die Bolzen (8) liegen jeweils innerhalb des Rahmens einer Schaltafel und bilden somit einen Gegenanschlag, so daß die Ecke einer Schaltafel jeweils zwischen einem Bolzen (8) und zwei Stegen (11) festgelegt wird und nur eine begrenzte Bewegbarkeit gegenüber diesen beiden als Gegenanschläge dienenden Teilen möglich ist.The webs (11) are placed between two adjacent formwork panels outside the frame of the formwork panels when installing a ceiling formwork and thus form a limit stop for the formwork panels. The bolts (8) each lie within the frame of a formwork panel and thus form a counterstop, so that the corner of a formwork panel is fixed between a bolt (8) and two webs (11) and only has limited mobility with respect to these two as counterstopings Sharing is possible.
