SPANNSCHLOSS ZUM VERSPANNEN VON RAHMENSCHALUNGSELEMENTEN
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 transverse bolt (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 transverse bolt (21) in the locking position delimits 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 crossmember (21) enables a greater stroke of the wedge (20) in the unlocking position.
