Abstract
The core shuttering is inside external shuttering, being particularly for the manufacture of concrete components, having means for adjusting the external measurements and elastic connections to cover joins and hold the outer parts together and seal them. The dimensions of the hollow chamber are adjusted by means of a supporting body (2) inside the outer parts (15) of the core shuttering and extending in the lengthwise direction of the core, carrying the adjusting mechanism (7) on which the outer parts are supported. These parts are sealed together by an elastic connection (16).
