PROCEDE DE FABRICATION DE DALLES ALVEOLEES EN BETON PRECONTRAINT EQUIPEES DE BOUCLES DE LEVAGE ET DE MANUTENTION AINSI QUE DALLES OBTENUES SUITE A LA MISE EN OEUVRE DE CE PROCEDE

摘要

The slab has lifting and handling loops (6) fixed on strands, where each loop is constituted by a bent metal rod with a gripping ring (7). The ring and related strand are coplanar to each other. Lateral bends (8, 8`) of the loop define locating lugs (9, 9`), and stirrup straps (10, 10`) are located in a plane perpendicular to the plane of the ring. The straps permit clippage by twisting of the loop along and on both sides of the strand. - An INDEPENDENT CLAIM is also included for a process of fabricating a series of hollow concrete slabs
