The invention relates to a support head (16) and to a ceiling support (14). The support head (16) is, in particular, planar and has a plurality of guide tabs. The guide tabs are arranged or designed in such a way that a formwork element (12) is secured on the support head (16) so as to prevent shifting, preferably at various positions. The support head (16) has widely opened first guide tabs, which lie opposite less widely opened guide tabs. This asymmetry of the support head (16) allows the support head (16) to be arranged close to a wall corner, while at the same time the formwork element (12) can be easily fastened. The invention further relates to ceiling formwork (10), comprising such a support head (16), a formwork element (12), and/or a beam.
