<p>The metal shuttering is for making the rear of a concrete window sill for supporting the woodwork. The shuttering consists of a bent steel plate (1), the top (2) of which acts as a support for the woodwork, and the bottom of which (3) as a support surface for fixing to the wall. Adjustable slides (6) are positioned at the required distance, and fixed by a system which may comprise screws (7) or cams. A rule is used for distributing the concrete and rests on the top (2) of the steel sheet section. The adjustable slide pieces enable window-sills of any size to be produced.</p> |
