Abstract
Abstract A support system for concrete forms, comprising form support means, each of said form support means comprising two similar and essentially parallelly extending and spaced substantially Zshaped profile elements, having traverse means applied to the profile web means for maintaining the Z-shaped profile elements spaced from one another and arranged in such a fashion with respect to the form sheathing that their oppositely directed or diverging flanges come to lie at the load side of the form support, while their flanges which confront one another at the girder side leave free between themselves a slot which is continuous and extends over the entire length of each of the form support means. Support clamp means fixedly clamp the girders with the form support means, these support clamp means being introduced from the front of the associated form support means into such and perpendicular thereto and through the support slot thereof. Coupling clamp means fixedly clamp support extensions introduced from the end into the form support means therewith, such coupling clamp means being introduced from the rear side of the form support means into such and through the support slot.
