1. A method for constructing a ceiling formwork for producing a ceiling element, comprising:
arranging two first ceiling props on a floor,
providing a formwork frame having:
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 which connects the first cross-support to the second cross-support,
a first unobstructed lateral recess on one longitudinal side of the formwork frame, and
a second unobstructed lateral recess on an opposite longitudinal side of the formwork frame,
connecting the first cross-support of the formwork frame to the two first ceiling props, the first cross-support having two first retainers for detachable connection to the two first ceiling props, the formwork frame being arranged in an intermediate position inclined downwards from the first cross-support along the connecting piece in a direction of the second cross-support,
arranging at least one of (a) at least one panel element and (b) at least one longitudinal support on the formwork frame in the intermediate position to obtain a formwork element such that said at least one of the at least one panel element and the at least one longitudinal support is detachably engaged with the first and second cross-support in the intermediate position;
swinging the formwork element up from the intermediate position into a substantially horizontal use position, and
supporting the second cross-support of the formwork frame of the formwork element with two second ceiling props.
