Three different types anchoring methods are used for hanging soffit stones: #1 – Non-Corrosive wire hooks cast in stone. #2 – Dowel with Eye or J-Bolts at joints. #3 – Threaded inserts cast in the stone.
Soffits are reinforced with reinforcing rods for a safe stone. Size of rods are as specified by the architect. Rule of thumb for reinforcing is 1/4 of 1% of cross section area.
The design of the steel frames and their position in relation to center line of joints in the soffit stones often dictate which type of anchoring is to be used. If steel angles are not over joints, dowels and bolts cannot be used as detailed. All anchors are to be non-corrosive. Refer to Specification Section.
