Supports or concrete formwork

A fitment for a prop, said fitment being adapted to support at least one shuttering element of the type used with concrete formwork, said fitment being adjustable between a full support position, and preliminary and full strip positions, said fitment comprising

• a shank connectable at one end to a prop,
• a shuttering tube longitudinally slidable in coaxial relation with said shank, said shuttering tube mounting at least one shuttering support member thereon,
• a support tube rotatably disposed in coaxial relation with said shank,
• locater means carried partially on said support tube and partially on said shuttering tube, said locater means being operative in a first rotational position of said support tube to maintain said shuttering tube in said full support position and said locater means being inoperative to maintain said shuttering tube in said full support position when in a second rotational position of said support tube, said locater means permitting said shuttering tube to drop into said full strip position when in said second rotational position, and
• screw threads on said shank and said support tube and connecting said shank and said support tube together in threaded relation, rotation of said support tube relative to said shank while said locater means is in said first rotational position causing said shuttering tube to move between said full support position and said preliminary strip position in response to said threaded relation between said shank and said support tube, and rotation of said support tube relative to said shank which causes said locater means to move into said second rotational position also permitting said shuttering tube to drop into said full strip position in response to the inoperativeness of said locater means at said second rotational position.
