The invention relates to a turnbuckle device (11) for clamping concrete shel l elements (1, 2). The inventive device is provided with two claws (12, 13) which can be moved against each other, and a wedge (18). The claws (12, 13) have limbs (14, 20; 41). The limbs (14, 20; 41) comprise bearing surfaces (3 0, 31, 43) which extend on a plane and which are used to bear cross struts (7, 21; 50) of frames (5, 6) made of concrete shell elements (1, 2). The limbs (14, 20; 41) also comprise projections (16, 22, 40) which are arranged on th e free ends thereof, said projections being suitable for engagement behind recesses (9, 15) in frames (5, 6) of concrete shell elements (1, 2). The invention is characterised in that an extension (17, 42, 44, 45) is provided on the projection (16; 40) of a limb (14; 41), said extension extending away from the bearing surface (30, 43) in an at least partially perpendicular manner on the plane of the bearing surface (30; 43) of the limb (14, 41). As a result, mounting of the turnbuckle device is made easier. |
