Abstract

Claims (44)

1. A system, comprising:

a formwork frame; and

two first formwork props;

wherein the formwork frame comprises:

a first cross-support,

a second cross-support,

a connecting piece which is longer than the first cross-support and the second cross-support, and which is arranged substantially perpendicular to the first cross-support and the second cross-support, and connects the first cross-support to the second cross-support,

a first lateral recess on one longitudinal side of the formwork frame, and

a second lateral recess on an opposite longitudinal side of the formwork frame;

wherein the first lateral recess is defined by a first portion of the first cross-support, a first longitudinal side of the connecting piece, and a first portion of the second cross-support, and wherein the second lateral recess is defined by a second portion of the first cross-support, a second longitudinal side of the connecting piece, and a second portion of the second cross-support;

wherein the first cross-support has two first retainers configured for detachable connection to the two first formwork props such that the formwork frame is arrangeable in an intermediate position inclined downwards from the first cross-support along the connecting piece in a direction of the second cross-support;

wherein at least one further element is configured to be detachably connected to the formwork frame in the intermediate position; and

wherein the formwork frame is pivotably movable from the intermediate position into a concreting position.

2. The system according to claim 1 , wherein the connecting piece is connected to the first cross-support and the second cross-support displaceably in a transverse direction.

3. The system according to claim 1 , wherein the connecting piece comprises two parallel pieces.

4. The system according to claim 1 , wherein the connecting piece extends along a longitudinal axis of the formwork frame, and wherein each of the first lateral recess and the second lateral recess has a respective length along the longitudinal axis that is greater than a respective width of each lateral recess.

5. The system according to claim 1 , wherein the at least one further element is at least one of at least one panel element and at least one longitudinal support.

6. The system according to claim 5 , wherein at least one further element comprises at least one longitudinal support arranged on each side of the connecting piece to support a formwork board.

7. The system according to claim 5 , wherein the at least one further element comprises two identical panel elements that are arranged on the formwork frame to form a rectangular formwork top.

8. The system according to claim 7 , wherein the two identical panel elements that are arranged on the formwork frame include a first panel element extending from the first cross-support to the second cross-support and arranged over the first lateral recess and a second panel element extending from the first cross-support to the second cross-support and arranged over the second lateral recess.

9. The system according to claim 1 , further comprising at least one of:

wherein the first cross-support has a first receptacle for detachable connection to the at least one further element in the intermediate position of the formwork frame inclined downwards from the first cross-support along the connecting piece in the direction of the second cross-support; and

wherein the second cross-support has a second receptacle for detachable connection to the at least one further element in the intermediate position of the formwork frame inclined downwards from the first cross-support along the connecting piece in the direction of the second cross-support.

10. The system according to claim 9 , further comprising at least one of:

wherein the first receptacle has a first receiving groove; and

wherein the second receptacle has a second receiving groove.

11. The system according to claim 10 , further comprising at least one of:

wherein the first receiving groove extends substantially in a direction of a longitudinal axis of the first cross-support, and

wherein the second receiving groove extends substantially in a direction of a longitudinal axis of the second cross-support.

12. The system according to claim 10 , further comprising at least one of:

wherein the first receiving groove has a first undercut for engagement with a first hook element of the at least one further element; and

the second receiving groove has a second undercut for engagement with a second hook element of the at least one further element.

13. The system according to claim 12 , further comprising at least one of:

wherein the first cross-support has a first retainer for detachable connection to one of the first formwork props, and

wherein the second cross-support has a second retainer for detachable connection to a second formwork prop.

14. The system according to claim 13 , further comprising at least one of:

wherein the first retainer has a retaining protrusion or a retaining opening for connection to one of the first formwork props, and

wherein the second retainer has a retaining protrusion or a retaining opening for connection to a second formwork prop.

15. A ceiling formwork for producing a ceiling element, comprising:

the system according to claim 1 , the first cross-support of the formwork frame being supported on the first formwork props; and

two second formwork props, on which the second cross-support of the formwork frame is supported.

16. The ceiling formwork according to claim 15 , further comprising:

a further formwork element; and

two third formwork props.
