Connector for upper flanges of concrete shuttering has compass linkage with lower ends of arms pivoted on axis perpendicular to face of shuttering

摘要

The connectors has a compass linkage (3) with a head (4) and two branches (5,6), each forming two bars (5A,B) which are parallel and articulated. The bars are pivoted at each end on axes which are horizontal and parallel to the shuttered surface. The base of each branch is pivoted on an axis (11) horizontal and perpendicular to the shuttering faces.
