| 摘要 |
<p>The invention relates to pillar formwork for use in concrete construction, which comprises a planar structure (1) forming the formwork and at least one connecting profile that is provided for linking, in a form fit, two opposite edges (3, 3') of the planar structure (1), thereby forming a tubular section . At least the surface of the connecting profile facing the planar structure h as a substantially constant curvature that substantially corresponds to the curvature of the tubular section.</p> |
