Fastening element for wall formwork

A method for constructing a formwork system for producing a building structure from cast-in-place concrete, wherein the method has the following method steps:

• I) mounting a fastening element on the edge region of a positionable formwork wall;
• II) setting up the positionable formwork wall;
• III) propping of the positionable formwork wall via a push-pull prop arranged on the fastening element;
• IV) insertion of a closing formwork wall below the fastening element.

A fastening element as an attachment point of a push-pull prop on a positionable formwork wall of a formwork system having the positionable formwork wall, a closing formwork wall, and the push-pull prop for producing a building structure from cast-in-place concrete, the fastening element comprising:

• a mounting part mountable in a reversible and detachable manner on an upper side of the positionable formwork wall and that defines an elongated hole configured to receive a first bolt;
• an angular element having
• a first leg that is removably engageable with the mounting part via the first bolt such that the angular element is displaceable along a direction of a longitudinal axis of the mounting part and is pivotable about an axis of the first bolt;
• a second limb arranged at an angle with respect to the first limb;
• wherein the push-pull prop of the formwork system is configured to be arranged on an end of the second limb, which projects freely to the push-pull prop such that the push-pull prop is configured to brace the positionable formwork wall while forming an arch with the positionable formwork wall and the fastening element over the closing formwork wall without directly connecting the closing formwork wall to the fastening element.
