CLAMPING AND FASTENING SYSTEM

This standardised fastening system creates point or linear fastenings and tensions load-bearing structures. The connection elements – and hence the forces acting on them – are automatically adjusted in the direction of pull. The system can be adjusted in three dimensions, enabling it to balance out manufacturing tolerances, making installation easier and reducing the planning effort to a minimum.

Point fastenings

Tennect

The corner of a membrane structure is generally fastened by two border cables which meet at a reference point. The two different force directions of these cables give a resultant which changes according to the load case. The resultant force direction can vary significantly, especially with asymmetric loads due to wind and snow. To solve this structural problem, the connection therefore has to be designed as a universal joint. TENNECT has a wide range of components for this purpose.

Features
  • Asymmetric loads balanced out
  • Automatic adjustment in the direction of pull
  • Freely swivelling fork head compensates tolerances in the cable lengths 

Ball head

Tennect

The development of the TENNECT ball head is the outcome of cooperation between our specialist engineers and external experts from the world of textile architecture. In a comprehensive study Horst Dürr and Dr Robert Roithmayr analysed hundreds of past membrane projects. The shared aim was to create a universal connecting element that is suitable for at least eighty per cent of all applications. After several development phases and detailed tests, the new TENNECT ball head was born.

 

Features
  • Freely adjustable angles
  • Very small component size

Linear fastenings

Tennect

In the past, a membrane either had to have holes punched in it at regular intervals around the border to allow it to be fastened with bolts or the welt had to be looped into a keder profile. Both these methods have serious drawbacks: whereas punching holes is expensive, complicated and prone to error, looping the welt into a profile is often difficult and takes time. Linear TENNECT fastenings are comprised of a special keder profile (welt section) which is bolted front to back; looping is no longer necessary.

Features
  • Fastening with two-piece aluminum welt sections
  • Sections with a finished surface, drilled holes or up to 6 metres long also available
