Self-supporting interconnectable formwork elements for the casting of especially wall constructions and a method for the use of said formwork elements

Abstract From the Canadian patent

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.
