<p>A column formwork for use in concrete construction is described, comprising a planar member 1 constituting the formwork, and at least one connecting section provided for form-fit connecting two opposing edges 3, 3' of the planar member (1) and th us for constituting a tube segment, wherein at least the connecting-section surface facing the planar member 1 exhibits a substantially constant curvature that substantial ly corresponds to the curvature of the tube segment.</p> |
