The invention relates to a ceiling joist formwork system (1) comprising a ceiling table (2), a vertical support (6), an inner board (3), a ceiling jo ist base (4), and an outer board (5), the outer board (5) and the ceiling jo ist base (4) being interconnected, especially rigidly interconnected. The ve rtical support (6) is rigidly fixed to the ceiling table (2), and the ceilin g joist base (4) is fixed to the vertical support. The system according to t he invention is characterised in that the ceiling joist base (4) and the out er board (5) are rotatably mounted about a first articulated point (GP1) on the vertical support (6), a guide (7) is rigidly fixed to the inner board (3 ), the inner board (3) and the guide (7) are rotatably mounted about a secon d articulated point (GP2) on the ceiling joist base (4), and the inner board (3) is guided by means of an edge (14a, 14b) in relation to the ceiling tab le (2) along a direction comprising at least one component vertical to the f ormwork upper plane of the inner board (3). The ceiling joist formwork syste m according to the invention can be used to simplify the dismantling, especi ally of the inner board, and the risk of damage to the inner board is reduce d.
