ABSTRACT:
Formwork with form panels 1 and connecting means, namely clamps 7 and/or bolts 11 includes closed, hollow marginal sections 2 having an abutment web 5 projecting at right angles to a lining skin 4 and extending along the outermost edge of the form panel 1 and serving to be laid tightly against a corresponding abutment web 5 or flat marginal strip 13 of a neighboring form panel. Holding webs 6 of the marginal sections 2 may have depressions 8 for application of clamp points. Oblong perforations or keyholes 10 for inserting connecting bolts 11 are provided side by side, in spaced relationship, longitudinally of the abutment web. The connecting bolts have projections 12 that jut out radially from an end of the bolt and engage behind the edges of the perforations in a locking position. The spacing and size of the perforations 10 corresponds with similar perforations 10 in marginal sections 2 or flat marginal strips 13 of adjacent form panels 1. The clearance between the projections 12 and an axially spaced counter-stop 14 of the connecting bolt 11 is approximately equal to the overall thickness of adjacent abutment webs 5 and/or flat marginal strips 13, so that form panels having either flat marginal strips 13 and/or hollow marginal sections can be connected to each other with the aid of such connecting bolts 11.
