Abstract

The formwork element, for inner and outer sheathing, esp. for casting hollow spaces in the interior of prefabricated concrete building components, such as for thermic insulation in walls, has two continuous walling bodies interconnected by a hinge and forming a square open space. These form wide-area interfacing parallel core sides which can be swivelled relative to each other, from outside, by means of the mechanical media hinged together inside, pref. under and lower angled shaped-sections. Several core units, each in two halves, may be hinged one above the other over the whole height of the hollow space required. Cores are simple, robust, easily inserted and re-usable.
