ABSTRACT:
A formwork assembly for casting a concrete structure includes a support member for supporting a conventional armature grid if any, further including at least one liquid-tight and load-bearing formwork wall connected to the support member. The formwork wall includes at least two panels, each defining a peripheral edging having at least one first dovetail joint element about its peripheral edging. Each formwork wall also has a panel connector having at least two second dovetail joint elements, each second dovetail joint element being complementary to the first dovetail joint element of a corresponding panel and is interlocked with the first dovetail joint element of a corresponding panel to form a dovetail joint, the connector holding the panels in an edgewisely juxtaposed fashion to form a continuous formwork wall. The formwork assembly includes a securing member for securing the connector and panels together, and a supporting structure for supporting the formwork wall.
