Fabric Structure V’s

We are getting down to the last few letters and The FabricArchitect still has words to use. When it comes to the letter “V”, the words that come to mind are:

  • Valley Cable
  • Verseidag Fabric
  • Velodrome

Valley Cables

Valley cables are pretty self explanatory but often misunderstood, poorly detailed or installed incorrectly. These cables are used to “keep down” the membrane from uplift forces on a structure.

Usually associated with “folded plate” style forms, they are normally constructed with a coated “jacket” on them because they are sitting on top of the membrane. They are sometime covered yet again after they are installed or left exposed to the elements. The end fittings require them to have some adjustment to them otherwise they have a tendency to flutter if not properly tensioned.

Verseidag Fabric

Verseidag is a manufacturer of membrane material located in Germany. They are one of the few companies worldwide that offer both PTFE and PVC fabrics. Duraskin is the brand name they go by for architectural membranes.

Velodrome

One of the more interesting and growing sports is the sport of bicycle or track racing. A Velodrome is an arena for Track racing.

Velodromes may be indoors or outdoors. Indoor tracks are not affected by weather and are more comfortable for spectators (i.e. see London 2012 Olympics). They ride smoother and last longer.

Despite the advantages of indoor tracks, outdoor velodromes are more common. However, there is more interest and fabric seems the be the material of choice for these venues.

“W” is next.
