Hooks & Inserts for Anchoring and Lifting

Anchor Hooks, Lifting Hooks and Inserts

Anchor Hooks, Lifting Hooks and Inserts

When the surrounding condition or the location of the anchor does not allow using the standard anchor slot or dowel hole the following may be used:

With cast stone, wire hooks may be cast in the stone and a strap or a bent rod may be tied to this for anchoring the stone.

Hooks are also cast in heavy stones for lifting. Where bolts are required for anchoring stone to steel, threading inserts are cast in the stone and tied with bolts to the steel frame. Mullions are fastened to the wall with clip angles as detailed. Sometimes thin stones (approximately 2″) are detailed with anchors that cannot be used. If pockets are provided for these anchors the remaining portion of the stone would be too thin and would fracture. With thin ashlar it is best to use dowels fitting a 1/2″ diameter hole or have wire hooks cast in the stone for tying anchors to the hook and back to the wall.

Base and Pilaster Stone Anchoring

Base and Pilaster Stone Anchoring

In Detail Section “C” the horizontal joint of the backup block is not in line with the top of stone. When this condition exists hooks are centered at the joints. At the same time of setting, straps are placed over the hooks and tied back to the block wall. Hooks in this position may be used for both lifting and anchoring.

With smaller base stones, two anchor slots are cast in the top of each stone and the stones are tied to the wall with strap anchors as detailed in the pilaster stone sections “E” and “F.” Stone lengths vary from 3′-0″ to 5′-0″.

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.
