Device for constructing wall of hardenable material in ground - uses preferably concrete and comprises templet comprising at least two spaced apart wall strips and first head strip connected along their longitudinal edges

摘要

A second head strip is fitted along the other longitudinal edges in order to form a closed templet rectangular in cross-section. The head strips (3, 4) are complementarily folded to form an overlapping connection between two adjoining templets. The one head strip is folded inwardly in V-formation and the other is folded outwardly in V-formation. The wall strip (1, 2) between the head strips are bent towards each other. The templet in cross-section has an S-shaped formation. Near to each head strip the templet is provided with a complementary connection for the adjoining templet.
