Description

The invention relates to a support device for concrete floors.

A support device for concrete floors with a telescopic steel support is z. B. from the DE 195 21 788 A1 known. To support formwork panels in the production of concrete ceilings, such steel supports are set up side by side as free building supports without mutual bracing.

The object of the invention is to create a support device as mentioned at the outset, which is improved in terms of its use.

• - einen ersten Träger und einen zweiten Träger, die um eine gemeinsame Schwenkachse miteinander schwenkbar verbunden sind und zwischen einer eingeschwenkten Ruhestellung, in der sie aneinander anliegend angeordnet sind, und einer ausgeschwenkten Abstützstellung, in der sie sich beidseits der Schwenkachse entlang einer Geraden erstrecken, verstellbar sind,
• - eine erste teleskopierbare Stütze, die im Bereich der Schwenkachse am ersten Träger schwenkbar angelenkt ist und relativ zu dem ersten Träger verschwenkbar ist zwischen einer am ersten Träger eingeschwenkten integrierten Ruhestellung und einer rechtwinklig zum ersten Träger ausgeschwenkten Stützstellung,
• - eine zweite teleskopierbare Stütze, die am zweiten Träger im Bereich seines der Schwenkachse gegenüberliegenden Außenendes schwenkbar angelenkt ist und zwischen einer am zweiten Träger eingeschwenkten integrierten Ruhestellung und einer rechtwinklig zum zweiten Träger ausgeschwenkten Stützstellung verstellbar ist, und
• - eine dritte teleskopierbare Stütze, die am ersten Träger im Bereich seines der Schwenkachse gegenüberliegenden Außenendes schwenkbar angelenkt ist und zwischen einer am ersten Träger eingeschwenkten integrierten Ruhestellung und einer rechtwinklig zum ersten Träger ausgeschwenkten Stützstellung verstellbar ist.

This object is achieved according to the invention by a support device for concrete ceilings, which has

• - a first support and a second support, which are connected to one another pivotably about a common pivot axis and are adjustable between a pivoted-in rest position, in which they are arranged adjacent to one another, and a pivoted-out support position, in which they extend along a straight line on both sides of the pivot axis are,
• - a first telescoping support which is pivoted in the region of the pivot axis on the first support and can be pivoted relative to the first support between an integrated rest position pivoted in on the first support and a supporting position pivoted out at right angles to the first support,
• - a second telescoping support which is pivoted on the second support in the region of its outer end opposite the pivot axis and can be adjusted between an integrated rest position pivoted in on the second support and a supporting position pivoted out at right angles to the second support, and
• a third telescoping support which is pivoted on the first support in the region of its outer end opposite the pivot axis and can be adjusted between an integrated rest position pivoted in on the first support and a supporting position pivoted out at right angles to the first support.

Such a support device supports formwork, formwork panels, ceiling formwork elements or the like when producing concrete ceilings of buildings. A telescopic support is a support whose length can be changed and adjusted. She can z. B. have a support base and a support or part and one of the two parts is interchangeable to change the length of the support against another support part with different length.

This object is also achieved by an arrangement according to claim 7 with at least two such supporting devices.

Advantageous developments of the invention are specified in the dependent claims.

The support device according to the invention is easy to transport and can also be used on construction sites where space is limited. The components of the support device are combined in one unit and can be transported as a unit. After concreting a ceiling, it is often not possible to use a lifting device such as a crane, which would otherwise be used to remove larger or larger-area formwork support devices when stripping the formwork. In particular, when only window or door openings are available for stripping, the supporting device according to the invention can be used in an ideal manner.

In a rest position, which can also represent a transport position, the carrier and the supports are expediently pivoted in towards one another and arranged lying parallel next to one another. This compact position facilitates the transport of the support device, in particular on a construction site, to the intended location for a concrete ceiling support or for the support of formwork elements and the like.

In the rest position, the supports are preferably arranged in a short, telescoped position. If necessary, they are adjusted from the short position to their telescoped long position for their supporting position. A telescopic support is basically a support that can be changed and adjusted in length. A lower part of the support can be fixed in different length positions on a upper part of the support connected to the carrier. If required, a lower support part can also be exchanged for another longer or shorter lower support part, so that such an embodiment is also a telescopic support.

Expediently, at the outer end of the first carrier and/or at the outer end of the second carrier, one or one additional carrier is or are pivotably arranged. In its supporting position, the respective additional carrier can lengthen or enlarge the supporting length or the supporting surface of the supporting device. Since the additional carrier on respective carrier is arranged, z. B. pivotable or movable, an additional component to be attached is not required.

The two carriers preferably contain bearing points for fixing cross braces, which can connect two supporting devices set up parallel next to one another. A defined distance between the two supporting devices can thus be set. In addition to the beams, such a cross brace can also be used to support formwork elements.

A locking device is expediently provided which keeps the two carriers locked in their linear support position.

Thus, the support device according to the invention can in particular position supports or tubular steel supports, which are set up as free construction supports next to one another without mutual connection or bracing, in a predefined arrangement and with a predefined distance from one another.

• 11 in an isometric view, two supporting devices arranged next to one another, which support a formwork element.

A support device 1, which is used to support ceiling formwork or element ceiling parts in the manufacture of concrete ceilings, has a first carrier 2 and a second carrier 3. The two carriers 2, 3 are connected to one another by means of a pivot bearing 4 about a common pivot axis 5 at their inner ends 6 and 7, respectively. The two carriers 2, 3 can be pivoted relative to one another in such a way that they can be in a carrying or supporting position ( 6 ) are pivoted apart and extend from the pivot joint 4 in opposite directions along a straight line. The two carriers 2, 3 form a flat support surface with their upper sides 8 and 9, respectively. The two carriers 2, 3 can be pivoted in relation to one another from the carrying or support position with their outer ends in such a way that they lie parallel to one another ( 1 and 2 ). This position represents in particular a rest or transport position of the supporting device 1. The carriers 2, 3 have z. B. a U-shaped profile or a double-T-shaped profile.

The support device 1 further includes a first support 10, z. B. a tubular steel support or an aluminum support, which has a support base 10.1 and a support upper part 10.2, which are mutually telescopic, so that the support length of the support 10 is adjustable. The support 10 is pivoted via its support upper part 10.2 in the area of the central pivot axis 5 on the first support 2 or on the pivot bearing 4. The support 10 can be pivoted relative to the first carrier 2 between an integrated rest position ( 2 and 3 ) and a supporting position pivoted out at right angles to the first carrier 2 ( 6 ). The first support 10 is in its integrated rest position ( 1 ) is set to such a length that it is received within the first carrier 2 and does not protrude beyond the first carrier 2.

The support device 1 also contains a second support 11 which is similar to the first support 10 and which is pivoted on the second support 3 in the region of its outer end 12 opposite the central pivot axis 5 by means of a pivot bearing so that it can pivot about an outer pivot axis 13 and between an integrated support which is pivoted in on the second support 3 rest position ( 3 ) and a supporting position pivoted out at right angles to the second carrier 3 ( 4 and 5 ) is adjustable. The second support 11 is thus arranged parallel to the first support 10 in its support position. A support lower part 11.1 is also telescopic relative to a support upper part 11.2.

The supporting device 1 also contains a third support 14 which is similar to the first support 10 and which is pivoted on the first carrier 2 in the region of its outer end 15 opposite the pivot axis 5 by means of a pivot bearing so that it can pivot about an outer pivot axis 16 and between an integrated rest position pivoted into the first carrier 2 ( 6 ) and a supporting position pivoted out at right angles to the first carrier 2 ( 7 and 8th ) is adjustable. In its supporting position, the third support 14 is thus arranged parallel to the first support 10 and to the second support 11 . A support lower part 14.1 is also telescopic relative to a support upper part 14.2.

It is therefore particularly advantageous that with the support device 1 in the rest or transport position ( 1 ) the carriers 2, 3 and the supports 10, 11 and 14 are pivoted into a compact arrangement against each other and lie parallel to each other.

The supports 10, 11 and 14 are expediently arranged in the rest or transport position in a short telescopic position. From the short position, the supports 10, 11 and 14 are adjusted for their support position in their telescoped long position.

According to a further embodiment it is provided that an additional carrier 17 is arranged at the outer end 15 of the first carrier 2 and/or an additional carrier 18 is arranged at the outer end 12 of the second carrier 3 . The respective additional carrier 17 or 18 can be adjusted and fixed on the first carrier 2 or the second carrier 3 via a swivel joint or via a sliding guide between a rest position on the carrier 2 or 3 and an extended or pivoted support position. The additional carriers 17, 18 thus lengthen the usable support length or support surface of the support device 1 in a simple manner without additional components to be attached.

A locking device can expediently be provided which keeps the two carriers 2, 3 locked in their linear support position.

At least two such supporting devices 1 can be arranged parallel to one another in the supporting position. 11 shows two supporting devices 1 arranged parallel next to one another, which support a formwork element 19, shown schematically by way of example, of a concrete ceiling to be manufactured. At least one cross brace is attached to the outriggers 1 (not shown) in order to firmly connect the respective beams of the two adjacent outriggers to one another and thus to define the distance between the two outriggers. The cross brace is arranged at right angles to the two beams it connects. Each carrier has bearing points with coupling devices to which the cross brace can be detachably fixed. The cross brace can expediently be fixed to the supports from below. In this way, the cross strut can also be fastened when the formwork elements are resting on the girders.

Such a support 10, 11, and 14 is z. B. a tubular steel support according to DIN EN 1065 or another support designed for the required load-bearing capacity.
