The Simpson HTHGQ truss girder hangers are a lower cost alternative to bolted hangers, the HTHGQ hangers for multi-ply girder trusses use Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws to provide high load capacities and easier installation compared to bolts. The HTHGQ is a high-load version designed to carry multi-ply trusses or composite lumber up to 5-ply girder trusses. For high-load capacities and easier installation compared to bolts, the HTHGQ is designed for use with Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws.
Installation:
- Use all specified fasteners.
- Can be installed filling round holes only, or filling round and triangle holes for maximum values.
- Strong-Drive SDS Heavy-Duty Connector screws supplied for all round and triangle holes. Installation may not require use of all Strong-Drive SDS Heavy-Duty Connector screws.
- All multiple members must be fastened together to act as a single unit.
- The thickness of the supporting girder must be equal to or greater than the screw length. For applications where the length of the supplied screws exceeds the thickness of the supporting girder, 3″ or 4 1/2″ screws may be substituted for the longer length screws with no load reduction, or a shim block may be used as approved by the Designer.
- Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2007 Section 7.5.3.5).
