Abstract
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 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.
Claims14
A framework for use with formwork to support the formwork for concrete casting and for stripping the formwork from a concrete surface, the framework comprising:
- a lower ground engaging frame including four tubular legs, an upper frame linearly moveable up and down between a first and a second position with respect to the lower frame, the upper frame including four legs, each one of which is located within a respective tubular leg of the lower frame and moves up and down telescopically with respect to the respective tubular leg of the lower frame, and an actuator provided on the framework that extends and retracts linearly moving the upper frame, where the upper frame supports and holds the formwork in place for concrete casting in the first position and linearly retracts to the second position;
- and
- a brace extending from a framework portion other than the upper frame to the concrete surface;
- wherein in use, the brace ensures that the movement of the upper frame from its first to its second position results in the stripping of the formwork from the concrete surface.
