<p>Retainers for support, so as to prevent falling over, are provided on the bottom part of an esp. telescopically length-variable support column in a formwork support (used in concreting ceilings). The retainers have at least two, pref. three, folding legs (7) arranged symmetrically round the support column (1). These are able to swivel in relation to the column, and are fixable at a defined angle to it (5). They can have one end hinged to a fixable socket (5) sliding along the column, and be fixable in their angle setting by connectors (12) attached between their ends, which may also be movably attached near the bottom column end. Readily transported and easily handled, this permits secure formwork erection and dismantling, with loads transferred to the base.</p> |
