However, the stiffeners always outside of that adjacent by the column axis Fixed supports fixed level, namely on the side of the extent, which is directed outwards. This will, however a torque is exerted on the supports around the support axis.
  • the stiffeners consist of simple tubes, the ends of which are flattened. There is an eye in each of these ends with which the rod end both in one of the outer tube of the scaffold part as well as one guided in the outer tube Inner tube radially protruding pins can be hung.
  • bracing frames are according to FR-A-2 147 430 with the help of cuffs that are open on one side vertical stands of the support tubes of the scaffold attached.
  • the sleeve surrounding the outer tube of a stand has a larger diameter than that for attachment certain cuff on the inner tube, the latter Cuff has a hole with a Inner tube radially crossing bore is aligned so that a bolt can be inserted through this hole, with which the stiffening frame can be attached at the top.
  • the larger one located at the bottom of the stiffening frame Cuff is not against displacement on the outer tube secured, it only has a hole in her Leg ends through which a bolt is inserted can be the cuff and thus the lower end of the stiffening frame on the outer tube, the Bolts outside the circumference of the outer tube through the leg ends the cuff is inserted.
  • the invention has for its object a bracing to develop for scaffolding that can take large loads can be arranged in the plane by two adjacent Supporting the scaffold is defined, but in handling is very easy.

  • the invention is not only suitable for supports in which the inner tube is telescopic, but also for Use in conjunction with supports known per se, at which the inner tube over a longer longitudinal section Has thread that is used to adjust the column height.
  • the invention can be implemented in connection with supports where the inner tube is round and the thread is cut over the entire circumference of the inner tube.
  • the cross section of the The inner tube of the support is not circular and the thread is only arranged in areas with a large outside diameter.
  • This embodiment of the invention has the advantage that in the peripheral portion, which have a smaller diameter and therefore do not wear threads, special brackets can be provided for the connection parts of the bracing, which is the usual threaded nut to support the Do not disturb the inner tube on the outer tube or vice versa.
  • the cross section of the outer tube can be circular or, in a particular embodiment of the invention, a Have cross section, the shape of the shape of the cross section corresponds to the inner tube, but for inclusion of the inner tube is larger than this.
  • this Outer tube and the inner tube radially projecting lugs, the protrusions running across the radius and on the radial inward side of these projections recesses for Entry of fasteners engaging behind the projections has, which are arranged on the stiffeners.
  • Such a cross-sectional formation of the outer and inner tube has the advantage that only one type of fastener must be arranged on the bracing, for example a kind of clamp that is designed so that it both the protrusions on the outer tube as well as the protrusions on Can reach behind the inner tube.
  • the receptacles provided on the outer tube and on the inner tube for the fasteners provided on the bracing can spaced apart along the tubes.
