Le mannequin de coffrage 1 est constitué d'un cadre inférieur 2 et supérieur 3 formé chacun d'au moins deux éléments horizontaux 4 et verticaux 5 fixés entre eux. Les éléments 4 et 5 comportent à chaque bout une extrémité 4a et 5a qui est inclinée d'un angle à 45 degrés afin de permettre, lors de l'assemblage desdits éléments, que ces derniers soient perpendiculaires deux à deux (figures 3 à 5).The formwork dummy 1 consists of a lower frame 2 and upper 3 each formed of at least two horizontal elements 4 and 5 vertical fixed between them.
