Anchor Bolt for wind turbine cage foundation is used to attach wind turbine to steel rebar and concrete structure. Anchor cage bolt requires high strength as well as anti-corrosion characteristic, so anchor bolt manufacturing include 2 processes: anchor bolt production and anti corrosion treatment. Anchor Bolt is mostly made of high strength steel 42Crmo steel rod, it is fastened onto anchor ring plate to form a cage shape and fixed with steel rebar and concrete structure for onshore wind turbine foundation. .
Why Anchor Bolt is So Important
Wind turbine anchor cage foundation failure always related to 2 parts: anchor bolt strength failure and concrete structure crack failure. Anchor bolt is the connection between anchor ring plate and steel concrete structure, if anchor bolt fails, it will lose the integrity and lead to further failures. Anchor cage foundation design, bolt length, configuration, materials are also critical to project safety.
Anchor Cage Bolt Length
Anchor cage bolt for wind turbine is a cast-in-place high strength fastener, wind turbine is a heavy equipment which need to be mounted on poured concrete structure. Why anchor cage bolt is long? Accident record of anchor cage bolt shows that short anchor bolt has higher risk of anchor bolt failures of crack in horizontal direction,as well as adding post-tensioning effect. A qualified designer can give a cost efficiency plan according to reality.
Main product of LongTeng is Anchor Cage foundation for wind power tower of onshore projects. In all, Longteng purchase high strength steel rod for anchor bolt assembly production, anchor cage will not be installed before delivery, installation is accomplished on site by professional workers.
