Abstract (en)
[origin: WO2011119036A1] Formwork column (1) comprising two flexible, thin-plate elements (2, 3) of mainly cylindrical shape and arranged mutually telescopically extendable with an outer element (2) and an inner element (3). Both thin-plate elements (2, 3) are provided with longitudinal, extending flanges (4, 5) provided with holes (6, 7) in a row in the longitudinal direction of the flanges, for closing of the formwork column (1) by means of locking plugs (8), while insertion of locking plugs (8) in adjacent holes (6, 7) also arrests the formwork length. The locking plugs (8) are tightened preferably by means of wedge shaped tightening members not requiring use of tools therefore.
