<p>A modular assembly for creating formwork for casting vertical concrete structures is characterized by elongated, generally concave elements (1) which are disposed in edge to edge relationship in two facing rows (4, 5 and 6, 7), and which are simultaneously retained in edge to edge relationship and in facing relationship by connecting members (8). The connecting members have spaced ribs (18) allowing the flow of concrete across the plane of the connecting member (8).</p> |
