Since the bolt do not press or fix the bottom cup to the vertical, the bolt goes straight through the cup and the cup simply rests on the bolt head.
  • Bolts are used as a vertical restraint as opposed to a clamping function. The bolts may come in varying sizes. Since the bottom cup rests on a head of the bolt, this is allowing a higher force to be applied through the head of the bolt and back into the vertical due to larger surface area between the bolt head and the surface of the vertical.

  • Gluing in combination with dowel pins, or local welding of high strength material, such as steel gives a structural reinforcement of the connection for load bearing components transferring and distributing loads to connecting components.
  • the bottom cup is rigidly fixed to the vertical by means of dowel pins of steel inserted and glued in pre-machined holes filled with glue in the vertical, preferably made of aluminium.
  • a bottom cup of the coupling agent, threaded onto the vertical is provided with pre-machined recesses arranged on its lower circumferential edge, matching the size and position of the configuration of the dowel pins, the bottom cup is then lowered down onto the matching dowel pins in the vertical.
  • Spot welding between the dowel pins and the recesses of the bottom cup, where both dowel pins and bottom cup are of the same weldable material, preferably steel, provide a firm, rigid and permanent connection of the bottom cup to the vertical.

  • a structural support system of the present invention is a flexible system able to take all kind of shapes, from right angled to complex curves. In heavy constructions with scaffolding elements, extra support of the structure is required.
  • the structural support system is able to also take poles arranged diagonally as a framework construction, alternatively or supplementary support brackets can be used in the corners or junction points between verticals and horizontals. Such support brackets easily grip and lock around the poles by loosening and fastening of bolts and nuts.
  • the present invention is backward compatible with the CUPLOK TM system, since the bottom cups of the present invention are designed to fit existing equipment utilizing the CUPLOK TM system. This is beneficial for the customer being able to easily adapt their existing equipment and save potentially high investment cost.
