Strongback SystemStrongbacksWhen openings are required in a tilt-up panel,they often create extreme bending stresses inthe remaining concrete sections. If additionalreinforcing steel is not an option, strongbackscan be used effectively to stiffen the panel.Strongbacks may be fabricated from lumber,aluminum or steel and are usually reusable.3/4” or 1” DiameterWing Nut and Washer3/4” or 1” DiameterCoil BoltPanelStrongbackStrongback InsertPanelSection ThroughStrongbackStrongback StiffenedTilt-Up PanelStrongback/Shore PostStrongback/Shore PostPanelCasting SlabStrongback SystemStrongback With FootStrongbackPanelWood Shoring FootCasting SlabStrongback-ShoreThe strongback-shore system is used to reduce stressesduring the lifting process and stabilize the panel during andafter erection. Generally, this system should be utilized onpanels where an offset opening is equal to or greater than1/2 the panel width. The concrete leg section must bechecked for stresses to determine if additional reinforcingsteel or strongbacks are needed.Strongback size should be of sufficient width and depth tocarry erection loads and consist of material strong enough towithstand repeated use. The shore depth should be the samenominal size as the panel thickness, i.e., a 6” panel wouldrequire a 4x6 or 6x6 shore.StrongbackPanelFillersShoreCounterSunkBoltWT-61 or T-2Insertsand T-76StrongbackPlateBlockingT-61 or T-1 InsertsStrongbackContractor to Provide LandingPad to Support Shore..5 W orless02-0967
