A B S T R A C T Formwork with form panels and means of connecting the same, namely connecting clamps and connecting bolts, comprises form panels having marginal sections that present a closed, hollow cross section and in each case have projecting at right angles to the lining skin an abutment that extends at the outermost edge of the form panel and serves to be laid tightly against a corresponding abutment of a neighbouring form panel. The marginal sections further having on a holding web approximately parallel to the abutment points of application in the form of depressions for connecting clamps embracing the marginal sections of adjacent form panels. Furthermore, perforations for inserting connecting bolts are provided side by side, in spaced relationship, in - and in the longitudinal direction of - the abutment webs of the hollow marginal section. In an end zone the connecting bolts having projections that jut out radially from the cross section of the bolts and engage behind the edges of the perforations in the anchoring or locking position, whereas, in a twisted position, the bolt with its projections may be inserted and withdrawn since the perforations are oblong or keyhole-like ones. The spacing and size of the perforations accords with the corresponding dimensions of such perforations in marginal strips made of flat material, forming part of further form panels.
