A form for supporting from below a layer of concrete during pouring and hardening has several square or rectangular panels having neighboring marginal portions with downwardly extending reinforcing skirts which are separably connected to each other by bolts. The panels rest on props which must be removed prior to separation of the panels from each other. In order to dismantle the form in the space below the hardened concrete layer, the props for one of the panels are removed and a dismantling device is separably coupled to a panel which is adjacent to the one panel. The dismantling device has a socket below the skirt of the one panel and the one panel is thereupon detached from the panel which carries the dismantling device so that the skirt of the one panel descends into the socket. The one panel is then pivoted with reference to the socketed part of the dismantling device so that its upper side moves away from the underside of the concrete layer. The dismantling device is thereupon transferred to another panel adjacent to a panel which is about to be detached.
