Formwork assembly for cantilever bridge apron has triangular structures each with two beams forming dihedron with angular opening rapidly set and locked with leg

摘要

Formwork assembly involve triangular structures (4) each with supporting beam (10), supporting formwork panels (6, 8), and bottom beam (12), resting on formwork plate (16), attached to each other by linking end (14) to form dihedron (10, 12). Leg (22) locks angular opening (A). Clearance (e) is situated near linking end allowing supporting beam to fold towards bottom beam during strip formwork. Angular opening can be set and locked rapidly and, for strip formwork, can be reduced rapidly as well.
