Abstract

One (1) of the boxes is on top and the other (2) at the bottom and each is fixed onto a central bar (3) which is fixed into the wall being constructed. Each of the boxes grips onto the bar by means of jaws (4, 4'). Each set of jaws (4, 4') is operated by a bottom return spring (5, 5'). The boxes have an unblocking device consisting of a push rod (6, 6') with its base (7, 7') positioned above the block (8) supporting the jaws (4). The blocking of each push rod in one of two positions is achieved by a ball-bearing (10, 10') pushed by a return spring (11, 11') and fitting into a spherical seating (12, 12', 13, 13'). The push-rods are operated by rods (14, 15) with two thrust pieces (16, 17) which act on support devices (20, 21).
