GFRC Installation Information
Using shop drawings and Stromberg recommendations, GFRC components should be installed plumb and level to required planes as designed and indicated.
If attachments to a framing system are required, it should be by stainless steel or corrosion resistant screws, adhesive, or hanging in accordance with manufacturer's recommendations. All GFRC assemblies should have no deflection greater than L/240.
Large GFRC units are usually connected to the structure by means of cast in metal frames constructed of metal studs or metal tubing. Metal studs are generally galvanized per ASTM A525 and conform to ASTM A446. Tubes are ASTM A500 Grade B. These frames are connected to the GFRC skin by flex anchors. Large GFRC units are erected with similar hoisting equipment to that used to erect precast concrete, except it can be smaller in capacity.
Smaller GFRC units may have cast in straps, wires, or inserts as needed. These are typically detailed in the GFRC shop drawing process.
Many smaller pieces of GFRC are typically installed by hand. Care should be taken when using straps, to not overly stress the GFRC units during installation.
Usually, GFRC units that have steel framing can be picked directly from the steel back up frame. In some cases jigs for lifting the GFRC may be needed.
