A locking mechanism for locking an inner tube with an outer tube of an adjustable telescopic push-pull prop assembly is disclosed. The locking mechanism includes a slotted prop nut having a slot and adapted to move in either direction when rotated on the outer tube having threads, a guiding ring adapted to be accommodated in the slot of the slotted prop nut, and a captive grooved pin assembly adapted to be accommodated in the guiding ring for locking and unlocking the inner tube and the outer tube such that the slotted prop nut encases the guiding ring and the captive grooved pin assembly. The positioning of the captive grooved pin assembly is such that it does not hinder the rotation of the slotted prop nut.

A connector assembly ( 400 ) for connecting a pair of formwork panels ( 200 ) with each other is disclosed. The connector assembly ( 400 ) includes a base component ( 402 ) having an arm, a first opening ( 602 ) formed on the arm, and a locking portion ( 406 ) formed at an end of the arm and adapted to be removably inserted in a second opening formed by alignment of respective slots ( 204 ) of the pair of formwork panels ( 200 ). The connector assembly ( 400 ) further includes a handle component ( 404 ) adapted to be partially disposed in the base component ( 402 ) through the first opening ( 602 ) formed on the arm. The handle component ( 404 ) is adapted to be operated to rotate the arm such that the locking portion ( 406 ) is rotated within the second opening ( 502 ) to partially lock the base component ( 402 ) in the second opening ( 502 ) for connecting the pair of formwork panels ( 200 ).

A multi-head bolt ( 10 ) having a bolt shaft ( 12 ) defining a longitudinal axis ( 14 ) of the multi-head bolt and a multi-head ( 16 ) disposed at a first end of the bolt shaft, the multi-head having at least three pawls ( 18 ), each pawl having a fixed radial orientation relative to the bolt shaft and having a primary plane being aligned with the longitudinal axis of the bolt shaft and having a support surface ( 20 ).

An alignment clamp sub-assembly ( 402 ) for connecting and aligning a pair of formwork panels ( 200 ) with each other is disclosed. The alignment clamp sub-assembly ( 402 ) includes a base component ( 502 ) to be disposed on a joint between a first formwork panel ( 200 - 1 ) and a second formwork panel ( 200 - 2 ). The base component ( 502 ) includes a first slot ( 504 ) formed on atop surface, and a second slot ( 508 ) formed on a front surface and adapted to receive a tie rod ( 406 ) in a lateral direction. The alignment clamp sub-assembly ( 402 ) includes a wedge ( 512 ) adapted to be received in a vertical direction in the first slot ( 504 ). The wedge ( 512 ) is inserted to lock the base component ( 502 ) on the joint and form the second slot ( 508 ) for receiving the tie rod ( 406 ).

The invention relates to a turnbuckle ( 1 ) for bracing frame formwork elements ( 2 ), comprising a first clamping device ( 7 ) which has a crossmember ( 9 ) and a first clamping jaw ( 10 ). The crossmember ( 9 ) has a toothed section ( 12 ) comprising a row of track teeth ( 13 ) which are arranged one behind the other and extend in parallel with one another. The turnbuckle ( 1 ) furthermore has a second clamping device ( 8 ) with a second clamping jaw ( 14 ) and a guide device ( 19 ). The second clamping device ( 8 ) can be moved in a bracing direction along the crossmember ( 9 ) towards the first clamping jaw ( 10 ). The turnbuckle ( 1 ) further has a wedge ( 20 ) which can be displaced in a guided manner by the guide device ( 19 ) along a wedge insertion direction and can be brought into engagement with at least one of the track teeth ( 13 ) in order to fix the two clamping devices ( 7, 8 ) in a bracing position with respect to one another. The guide device ( 19 ) has a cross brace ( 21 ) which can be displaced transversely to the wedge insertion direction between an unlocking position and a locking position. The crossmember ( 21 ) is designed and arranged in such a way that the cross brace ( 21 ) in the locking position limits a stroke of the wedge ( 20 ) in a direction orthogonal to the toothed section ( 12 ) in such a way that the wedge ( 20 ) in the clamping position can be brought into engagement with the at least one track tooth ( 13 ). The cross brace ( 21 ) enables a greater stroke of the wedge ( 20 ) in the unlocking position.

A filler beam assembly of a formwork structure is disclosed. The filler beam assembly includes a beam having a first end and a second end distal to the first end. The first end and the second end are adapted to be in contact with top plates of respective drop head assemblies. The beam includes a top surface having a drophead interface edge at the first end and a drophead interface edge at the second end. The filler beam assembly includes a first lip formed on one side of the beam and adapted to accommodate one of a timber runner and a PU insert for being nailed with a plywood positioned adjacent to the top surface of the beam, and an additional lip disposed below the first lip and adapted to be accommodate a head portion of a cross beam.
