Abstract

Curved arm for steel constructions of all types consists of a central connection piece or toggle joint and two couplings or pressure members. The toggle joint is formed by a core piece and arched template and the pressure members can be adapted to the toggle joint according to the desired incline of the roof work. Each pressure member is formed by a profile or profiled steel member consisting of two lower chords and a core piece with changeable cross section. The core piece enables the pressure member to adapt to different rolling mill products.
