<p>An adjustable sliding form or shuttering for concrete casting of buildings comprises relatively movable form sections to permit contraction and/or enlargement of the sliding form by the action of width regulating means to vary the width of the building, yoke-shaped scaffolding members carrying the sliding form and the scaffolding thereof for vertical movement, and climbing means operating the sliding form and the scaffolding thereof. Each of the movable form sections operable by the width regulating means is freely pivotally mounted in the scaffolding at a point above the form section to permit said form section to freely adapt itself to the width adjustment initiated by the width regulating means at the single mounting point.</p> |
