An extension of the THGB/THGBH/THGW series, these high-capacity hangers are designed for attaching 2-ply, 3-ply or 4-ply sized structural composite lumber (SCL) to a girder truss. The THGBV offers optional installation with Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws, while the bolted THGBHV and THGWV offer higher load capacities. Two bucket heights are available for each width to accommodate a range of SCL sizes. Options for skewing or dropping the buckets for conditions where the SCL joist is lower than the girder bottom chord provide additional design flexibility for a variety of SCL-to-truss connections.
Simpson Strong-Tie® gray paint
Use all specified fasteners; see General Notes.
All multiple members must be fastened together to act as a single unit.
Maximum 11 7/8" bottom chord in the carrying member to allow for the minimum bolt end distance.
Bolts must be installed symmetrically when using less than 8 bolts on the 8-bolt backplate.
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).
Shall be attached to a 2-ply girder truss to allow for required minimum screw penetration. Strong-Drive SDS Heavy-Duty Connector screws require a minimum 2-ply (3") carrying member.
See Hanger Options information.
THGB/THGBH/THGBV/THGBHV hangers can be skewed to a maximum of 45°. Allowable download or uplift is 0.87 of table load.
THGB/THGBH/THGBV/THGBHV hangers can be skewed to a maximum of 45°.
The maximum allowable down load and uplift load for skew is 0.87 of the table load.
THGBV/THGBHV backplates can be extended to allow for up to a 6" dropped bucket.
Allowable loads are 100% of the table loads.
Order as “X” version, specify the total backplate height, BK_PLT, equal to the hanger height (H) plus the dropped bucket amount (db). Ex: a THGBV3.62 /9 with a 4" dropped bucket would have a total backplate height of 27 1/4".
Bolts and Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws are permitted to be installed through metal truss connector plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2014 Sections 126.96.36.199 and 8.9.2 are met.
Wind (160) is a download rating.
To achieve published loads, machine bolts (MB) into the girder truss shall be installed with the nut on the opposite side of the hanger with a standard cut washer (except THGWV's). Standard cut washers are required for THGBV and THGBHV.
