A circular Cablenet tension wire grid system was installed at the Roundhouse in Camden as part of a 29.7 million refurbishment project. The Cablenet installation for this project is doughnut shaped with no intermediate supports.
The most exacting engineering element of the project was ensuring that the inner and outer ring beams up in the roof were strong enough to absorb the tension loadings of the cable assemblies, and designing them to be robust enough to suspend the grid frame from tie bars connected to the roof support structure.
The grid’s frame has no support struts between its inner and outer frames – it is all woven in 4mm diameter wire. The outside diameter ring beam measures 14.3 metres and the inside is 3 metres in diameter, giving a total grid area of 147 square metres .
The tension wire grid frame was assembled on the Roundhouse floor and lifted into its final location using nine 1.5 tonne chain blocks – in a delicate operation overseen by the Slingco installation team. It took a day to lift and fix the grid into its final position at its full height of 12 metres. This was a really tricky process as the grid needed to be picked up and raised, millimetre perfect, in exactly the right position in relation to the support steelwork and pre-positioned hanger locations.
Alignment was achieved using plumb lines, probably the same methodology that the Victorians would have used!
...excellent experience working with Slingco ... always conscientious and meticulous in their attention to detail...
We can install Cablenet in new buildings or retro-fit to old; we can construct it in virtually any size or shape; and, using the experience we’ve gained since first introducing the system more than 20 years ago, we can design it to provide an economical solution to even the most challenging of building layouts.
