The HHSUQ is a high-load, face-mount, truss-to-truss hanger designed to accommodate severe skews (45°-84°) for hip trusses, enabling a greater range of installation applications. Fastening the HHSUQ with Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws makes installation fast and easy, while eliminating the inconvenience of bolted applications.
Back plate — 3 gauge; stirrup — 7 gauge
Simpson Strong-Tie® gray paint
Use all specified fasteners; see General Notes.
The joist/truss end may be square cut or bevel cut. 3 7/8" minimum heel height.
Strong-Drive SDS Heavy-Duty Connector screws supplied for all round holes.
All multiple members must be fastened together to act as a single unit.
Allowable Uplift loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
Strong-Drive® SDS Heavy-Duty Connector screws that penetrate all plies of the supporting girder (screws must penetrate a minimum of 1" into the last truss ply) may also be used to transfer the load through all the plies of the supporting girder. When Strong-Drive SDS Heavy-Duty Connector screws do not penetrate all plies of the supporting girder truss, supplemental Strong-Drive SDS Heavy-Duty Connector screws at the hanger locations may be required to transfer the load to the truss plies not penetrated by the face fasteners, as determined by the Designer. 3" long Strong-Drive SDS Heavy-Duty Connector screws into face may be replaced with 4 1/2" or 6" long Strong-Drive SDS Heavy-Duty Connector screws with no load reduction.
Loads shown are based on a minimum 2-ply 2x8 carrying member. For single 2x carrying members, replace 3" long Strong-Drive SDS Heavy-Duty Connector screws face fasteners with 1 1/2" long Strong-Drive SDS Heavy-Duty Connector screws and reduce the allowable download to 2,630 lb. for DF/SP and 1,895 lb. for SPF/HF. The tabulated allowable uplift load is not reduced.
Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2014 Section 22.214.171.124).
Truss chord cross-grain tension may limit allowable loads. Designer to refer to ANSI/TPI Section 126.96.36.199 for connection details, limitations, and reductions.
Simpson Strong-Tie® Strong-Drive SDS Heavy-Duty Connector screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2007 Sections 188.8.131.52 and 8.9.2 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
For installations into LSL or PSL, use DF/SP table loads.
