Device for fastening at least one dowel or the like in a shuttering for structural parts consisting of concrete

摘要

On a shuttering (1) for producing structural parts - predominantly sleepers consisting of concrete - on a conveyor belt (4), sleeve-shaped built-in parts - predominantly dowels (10) - are fastened on the base part (3) by a retaining screw (12) formed by a head (13), a cylindrical shaft (14) and a threaded part (15). The dowels (10) are held by the threaded part (15), which engages in a frictionally locking manner into the thread (20) of the dowel (10) with approximately one to two thread turns of a rail screw. The retaining screws (12) are tightened or loosened by machines (22, 24) set up beneath the conveyor belt (4). <IMAGE>
