TILT-UP CONSTRUCTION - Brock White

General and TechnicalInformationGeneral andTechnical InformationInsert Edge DistancesPEmbedment of inserts closer to any edge; constructionjoint; window or door opening than the minimum edgedistances shown in this handbook will greatly reduce theeffective area of the resisting concrete shear cone and thusreduce the insert’s tension safe working load. The shadedarea of the shear cone indicates the extent to which this areais reduced. Tension safe working loads of inserts near a freeedge or corner must therefore be reduced in proportion to thereduction in effective shear cone area.d e = Actual edge distanceD = Minimum edge distance required todevelop insert’s SWLDd eMinimum Insert DistancesLedgeProjec15"Minimum10 o Max (Ten Degrees Max)10ß Max.15" MinimumSeeIllustration6" Minimum6" Minim15" MinimumLedger orProjection15"MinimumT-41GroundReleaseInsert15"MinimumLedger orProjectionWarning!

If dynamicforces or impact load conditions are anticipated, the safeworking loads must be reduced accordingly.Care must be exercised to ensure that all inserts andhardware are properly aligned, all lifting plates and bolts areproperly secured, all rigging is equalized and that propersize crane cables are used. The centerline of the spreaderbar and hook must be on the centerline of the panel and thecrane cables must be of proper size and length.Warning! Users of Dayton Superior products must evaluate theproduct application, determine the appropriate safety factor, calculatethe applied loads and control all field conditions to prevent excessiveproduct loading.When uncertain about proper installation or use of a Dayton Superiorproduct, contact Dayton Superior for clarification. Failure to do somay expose workers to hazards which could result in serious injuryor death.10 02-09
