ABSTRACT:
An unsupported form system for ceiling formworks is disclosed which comprises of three elements, i.e. extensible shores, head elements on the top of said shores and form boards to be positioned directly on the head elements. The head elements have flat supports for the boards which, for their part, have an open frame, the edges thereof cooperating with truncated pyramid noses on said supports. The boards may be suspended on the head elements of erected shores from below and may be brought into their horizontal operational position with the next shores once these have been erected. Pivotal levers are used for supporting adjacent boards between those which are supported directly on the head elements which interconnect said shores in pairs.
