The invention relates to a ceiling formwork (1) having formwork panels (2) comprising rectangular edge webs (3) horizontally disposed in the usage position, and supporting means, such as carriers (15) and/or supports (17) for said formwork panels (2), and a holding element (4) gripping the edge webs (3) of adjacent formwork panes (2) in the corner region, said element comprising centering protrusions (5) for the edge webs (3) of said formwork panels (2) and intersecting openings (6) that are open toward the top, extending horizontally between the centering protrusions (5) in the usage position, which are limited by lateral centering surfaces (7) of the centering protrusions (5). These lateral limitations or centering surfaces (7) of the openings (6) approximate each other from the top to the bottom at least up to a distance from each other that corresponds to the total thickness of two edge webs (3) of two formwork panels (2) in contact with each other in the usage position, wherein a groove-like intermediate space (12) may be provided beneath this closest approximation of the centering surfaces (7) as a continuation of the centering surfaces (7) in order to positively encompass the edges of the edge webs (3) of the formwork panels (2).

L'invention concerne un coffrage de plafond (1) comportant, en position d'utilisation, des panneaux de coffrage (2) orthogonaux, horizontaux, dotés d'éléments de liaison de bordure (3), et des moyens de support tels que des poutres (15) et/ou des colonnes (17) pour les panneaux de coffrage (2), ainsi qu'un élément de maintien (4) maintenant, dans la zone angulaire, les éléments de liaison de bordure (3) de panneaux de coffrage (2) voisins, lequel élément de maintien comporte des parties en saillie de centrage (5) pour les éléments de liaison de bordure (3) de ces panneaux de coffrage (2) et des ouvertures de passage (6) entre lesdites parties en saillie de centrage (5), lesquelles ouvertures se croisent à l'horizontale, sont ouvertes vers le haut en position d'utilisation et sont limitées par des surfaces de centrage (7) des parties en saillie de centrage (5). Les limites latérales ou surfaces de centrage (7) des ouvertures de passage (6) vont en se rapprochant les unes des autres de haut en bas, au moins jusqu'à un intervalle mutuel qui correspond à l'épaisseur totale de deux éléments de liaison de bordure (3) se touchant en position d'utilisation de deux panneaux de coffrage (2) respectifs. Sous ce plus grand rapprochement des surfaces de centrage (7) peut se trouver un intervalle (12) de type rainure en tant que prolongement des surfaces de centrage (7) qui entoure par complémentarité de forme les bords des éléments de liaison de bordure (3) des panneaux de coffrage (2).
