INNOVATIVE ANCHORING SOLUTIONS
We introduce Peikko’s FatBar Foundation system.
SUCCESSFUL PROJECTS ARE BUILT ON SOUND FOUNDATIONS
ASSEMBLY
FatBars are assembled with DIN 6319 washers and DIN 6330 B nuts, both class 10. These washers and nuts have spherical contact area that ensures full contact even if the anchor is tilted, thus eliminating uneven tension and bending of washer.
SPECIFICATIONS
FatBars are available in lengths up to 6000 mm with an option of localized zinc plasma metallization to exposed area (offering HDG comparable corrosion protection but without dangerous effects to high strength steel).
The use of greater capacity anchors leads to smaller and fewer anchors, resulting in smaller bottom flange of tower, less congestion and overall a more economic design.
PEIKKO FATBAR FOUNDATION SYSTEM ACHIEVES EUROPEAN TECHNICAL APPROVAL With over 45 years experience of foundation technology and over 5 million anchors produced, Peikko Group have recently achieved ETA for FatBar anchors contained within their innovative turbine foundation system.
FIRST POST TENSIONED ANCHOR BOLT
FatBar is the first post tensioned anchor bolt designed specifically for wind turbine foundations, sustaining larger fatigue loads than traditional grade 10.9 bolts. Bolt threads are cold-rolled with a special threading designed specifically for fatigue loading. Additional preparation increases fatigue resistance.
Post tensioning is with maximum force according to EN 1992-1-1for example…
Peikko Fatbar 36 fpk=1070kN -V- M36 grade 10.9 fpk=817kN ➜ 30% capacity increase
INTEGRATED SOLUTION Peikko system offers an integrated solution of foundation design support and the manufacture and supply of atBar, top and bottom flanges and punching reinforcement resulting in a foundation using less steel and concrete than traditional designs.
Piekko is proud in developing solutions which help customers to more rapid, economic and reliable construction.
