A scaffold platform section is fashioned as a corner platform section (117) and exhibits an optionally multipartite floor plate (27) at which at least one supporting leg (29) is bent at an angle, carrying drop-in claws (13) or the like. A supporting leg has a lower lift-preventing leg (30) extending to below the U supporting span member (14) in the drop-in position. This platform section bridges a great variety of different angular regions between other scaffold platforms and can have a swivel member (37) for compensating purposes. The corner platform section (117) proper can be equipped with a border leg (35). The swivel member (37) can have a border leg (38). Two component elements can be joined in a swivelable and inflexible fashion.
