Abstract

The free edges of two horizontal shuttering sections (1, 2) are reinforced by corner-pieces (3, 4) on which are soldered caps (5, 6). Pawls (7, 8, 9, 10) are hinged on the caps (5, 6) on vertical axes (11, 12, 13, 14). The pawls and vertical axles are joined by pins (15, 16). Underneath the pawls (7, 8, 9, 10) are soldered pivots (17, 18) on which are hinged pivoting caps (39, 40) which are held on the pivots (17, 18) by bars (19, 20) and washers (21, 22). The caps (39, 40) are joined by a rod (23, 24) parallel to the pawls (7, 9 or 8, 10) of the same shuttering section. The ends of the rods (23, 24) have rings (26, 25) hinged at (28, 27) in which fits a lever. Each pawl (7, 8, 9, 10) has a truncated-cone-shaped catch which fits into a corresponding hole (31, 32) in the other pawl.
