The invention is a frame for use with formwork to support the formwork for concrete casting and for stripping formwork from a concrete surface where a frame (16, 23) is moveable between a first and second position that supports and holds formwork in place for concrete casting in a first position and that retracts to a second position so as to lower the formwork away from the concrete surface wherein sufficient force is applied to the formwork as the frame retracts to the second position to strip it from the concrete surface. The invention provides a means of both supporting formwork during concrete casting as well as a means of stripping and lowering the formwork after the concrete is cast.

L'invention concerne un cadre destiné à être utilisé avec un coffrage pour supporter le coffrage pour le coulage de béton et à retirer le coffrage à partir d'une surface de béton où un cadre (16, 23) est mobile entre une première position et une deuxième position. Le cadre supporte et maintient le coffrage en place pour un coulage de béton dans une première position, et se rétracte dans une deuxième position de façon à abaisser le coffrage à l'opposé de la surface de béton, une force suffisante étant appliquée au coffrage lorsque le cadre se rétracte dans la deuxième position de façon à le retirer de la surface de béton. L'invention prévoit des moyens pour supporter le coffrage durant le coulage de béton ainsi que des moyens pour retirer et abaisser le coffrage après que le béton a été coulé.
