Adjustable concrete wall shuttering - fits on horizontal screwed spindle in steel strip cast in concrete floor

摘要

The adjustable concrete shuttering is for positioning a wall to be cast on a concrete floor. It is used in conjunction with a steel strip (4) cast in the floor and protruding from it on the centre line of the wall to be cast. The strip accommodates a horizontal screwed spindle (1). A support (3) is fitted over one end of the latter, to bear against shuttering (6). After adjustment, a similar support (3a) is fitted over the other end, acting against the other shuttering (2).
