ABSTRACT:
A form for use in shutterings for the pouring of concrete has a panel with a marginal portion reinforced by a hollow frame having an outer wall which is normal to the panel and a second wall remote from the panel, integral with the outer wall and having one or more sockets for reception of the working end of a crowbar serving to lift and/or otherwise displace or reorient the form. Each socket can constitute a recess or an opening in the second wall. The second wall is or can be disposed between the outer wall and an inner wall which is parallel to the outer wall and extends to the rear side of the marginal portion of the panel. The second wall can be reinforced in the region where it is engaged by the working end of the crowbar in order to reduce the likelihood of deformation of the frame, particularly of the outer wall which contacts a support, abuts a ceiling or is in abutment with the frame of an adjacent form in an assembled shuttering.
