Reinforcing

Window Sill and Head Band

Window Sill and Head Band

(includes general notes about reinforcement)

Cast Stone is stronger than most natural cut building stones and therefore will generally require no reinforcing when used as a replacement for natural cut stone.

When desired, Cast Stone can offer the beauty of natural stone with the structural advantages of precast concrete by including reinforcing bars in the design. Design reinforcement the same as for precast concrete except that wire mesh and reinforcing cage assemblies should not be used. Instead use deformed bars meeting the requirements of ASTM A615. We use grade 60 epoxy-coated bars in all cases where reinforcement is shown.

Where reinforcing is required due to structural stress, temperature changes or safety in handling large pieces, refer to Specification Section on reinforcing.

Soffit Stones

Soffit Stones

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.
