Iron Casting Scaffolding Fittings Rock Bolt Expansion Anchor With Expansion Shell
Application
Expansion shells are used for fixing single-sided shuttering or
similar structures in rock, concrete or comparable load-bearing
ground.
The expansion shells hold in any rock strata which is sufficiently
competent to provide an adequate anchorage. They are designed to
anchor in soft ground or hard rock. In good strata the anchorage
exceeds the ultimate strength of the steel bolt. All expansion
shells require a competent strata in the anchor zone. The
suitability of the anchorage and the specific expansion shell to be
used is best determined by physical load testing. The expansion
shells feature parallel contact with the hole wall with sharp
serration’s on the outside leaves ensure positive holding power.
