SLIP FORM—System of formwork for concrete which permits continuous casting. Weballow adequate cover or hook extension for 90-degree hooks (Fig. 3). Alternatively, we detail 90-degree hooks with the hooks rotated to reduce the projected length of the hook extensions. Rotating the hooks is easily accomplished on vertical dowels, because the hook extensions are horizontal, and generally rest on and are tied to continuous bars.
