A connector for tying together opposed foam panels in spaced and parallel relationship makes a form for receiving flowable material. The connector comprises a pair of anchor members, one being devised to be embedded in one of the foam panels and the other being devised to be embedded in the other one of the foam panels. Each of these anchor members has a projecting end devised to come out of the foam panel once the anchor member is embedded therein. The connector further comprises a web member extending between the foam panels. The web member has opposite longitudinal side ends, each of the side ends being hingedly connectable to the projecting end of either one of the anchor members. Thanks to such a connector, the tied foam panels of the form wall assembly 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 for transportation purposes. Advantageously, a wall form made using such connectors can be pre-assembled at the factory and is as easy to ship to the site of construction as disassembled wall forms.

[ What is claimed is:] [1.]1. 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; anda 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;an elongated link element connected longitudinally to the flange plate and having a projecting end coming out of the foam panel, the projecting end of each anchor member comprises a stabilising plate parallel to the flange plate extending flush with an inner surface of the foam panel and a plurality of aligned open slotted tube-like knuckles disposed on the stabilising plate, each tube-like knuckle forming an inner tube having a pair of longitudinal opposed edge portions defining a slot in registry with the slots of the other knuckles, anda web member extending between said foam panels, the web member having a first longitudinal side end opposite a second longitudinal side end, each longitudinal side end of the web member defining an enlarged end portion sized to be slidingly insertable in said open tube-like knuckles and a strip portion connecting the enlarged end portion to a central portion of the web member, the strip portion having a width sized so the strip portion is slidingly insertable in said slots of the anchor members, and the strip portion including a plurality of aligned slits each adapted to receive an edge portion of the knuckles, 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 anchor member;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.
