A locking system (24) for securing adjacent concrete form panels (20a, 20b) together during assembly of a concrete form (22) is disclosed. The locking system (24) includes a mounting block (50) which is removably attachable to one of the adjacent panels (20a, 20b). A slide member (52) is mounted for sliding movement relative to the mounting block (50) between a first position retracted from aligned apertures (48) in side members (30) of the adjacent panels (20a, 20b) and a second position extending through the aligned apertures (48). The slide member (30) includes a bolt member (92) mounted to rotate within the mounting block (50) in its extended position between locked and unlocked positions to secure the adjacent panels (20a, 20b) together. Alternatively, the bolt member (206) is configured to receive a wedge member (204) at its projecting end or has a clamping member (304) mounted to rotate on the bolt member (306) for securing the adjacent panels (20a, 20b) together.
L'invention concerne un système de blocage (24) destiné à fixer ensemble des panneaux de coffrage à béton contigus (20a, 20b) lors de l'assemblage d'un coffrage à béton (22). Ledit système de blocage (24) comporte un bloc de montage (50) fixé amovible à l'un des panneaux contigus (20a, 20b). Un élément coulissant (52) est monté de manière à coulisser par rapport au bloc de montage (50) entre une première position retirée des ouvertures (48) alignées dans les éléments latéraux (30) des panneaux contigus (20a, 20b) et une seconde position traversant lesdites ouvertures (48) alignées. L'élément coulissant (30) comporte une cheville (92) montée de façon à tourner dans le bloc de montage (50) dans sa position allongée entre des positions verrouillée et déverrouillée pour fixer les panneaux contigus (20a, 20b). Autre variante, la cheville (206) est conçue pour loger un coin (204) à son extrémité saillante ou un élément de serrage (304) monté de manière à tourner autour de la cheville (306) pour fixer ensemble les panneaux contigus (20a, 20b).
