A b s t r a c t One has aimed at providing interconnectable disposable formwork elements for the casting of for instance foundations, sustaining walls etc. in concrete and which, as compared with conventional formwork doors, gives a cheaper formwork and wherein the formwork operation is more rapidly effected, at the same time as it may be done by a person not skilled in the trade. For this object, each formwork element (1) consists of an elongated, thin-walled, cylinder- shaped element, which in per se known manner is provided with coupling means (2, 3) cooperating with corresponding or complementary coupling means on the neighbour element(s) for the interconnection of adjacent cylinder-shaped formwork elements so that one, upon filling of concrete into the interconnected cylinder-shaped formwork elements, attains a row of fused concrete columns constituting a wall on which the formwork elements may form the external surface(s) or from which the external portions of the formwork elements may be removed.
