Concrete wall form and connectors therefor

A form wall assembly to make a form for receiving flowable material, the form wall assembly comprising:

• a first and a second opposed foam panels in spaced and parallel relationship;
• and
• a plurality of connectors tying together said first and second foam panels, each connector comprising:
• a pair of anchor members, a first one embedded in the first foam panel and the second one embedded in the second foam panel, each anchor member having:
• an elongated flange plate extending longitudinally and deep inside the foam panel;
• and
• an elongated link element connected longitudinally to the flange plate and having a projecting end coming out of the foam panel, the projecting end comprising:
• a stabilising plate parallel to the flange plate and extending flush with an inner surface of the foam panel;
• a plurality of connecting elements projecting from the stabilising plate, each connecting element comprising a longitudinally extending pivot pin;
• and
• a web member extending between said foam panels, the web member having a first longitudinal side end opposite a second longitudinal side end, said first longitudinal side end being hingedly connected to the projecting end of the first anchor member and the second longitudinal side end being hingedly connected to the projecting end of the second web member;
• each of said longitudinal side ends defining a plurality of arms cooperating with each of the connecting elements, each arm having an extremity pivotally connected to the pivot pin of a corresponding connecting element so as to be rotatable around an axis defined by said pivot pin, thereby allowing the web member and anchor member to pivot with respect to each other;
• whereby the tied foam panels are movable between an extended position where the foam panels are spaced-apart to make the form and a collapsed position where the foam panels are brought close to each other.
