Description
An extension of the THGB/THGBH/THGW series, these high-capacity hangers are designed for attaching two-ply, three-ply or four-ply sized structural composite lumber (SCL) to a girder truss. The THGBV offers optional installation with 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.
Material
- 3 gauge
Finish
- Simpson Strong-Tie gray paint
Installation
- 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 fewer than eight bolts on the eight-bolt backplate.
- Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref. ANSI/TPI 1-2014 Section 7.5.3.5).
- Shall be attached to a two-ply girder truss to allow for required minimum screw penetration. Strong-Drive SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
Options
Skewed Seat
- THGBV/THGBHV hangers can be skewed to a maximum of 45°.
- The maximum allowable download and uplift load for skew is 0.87 of the table load.
Dropped Bucket
- 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".
Product Information Tables
Load Tables
- Allowable loads are based on a SCL (LVL, PSL, or LSL) carried member with an allowable F'c ⊥ of 750 psi and equivalent Specific Gravity of 0.50 or higher.
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- A three-ply carrying member is required for the THGWV5.50 /9 and THGWV5.50 /11; a four-ply carrying member is required for the THGWV7.25 /9 and THGWV7.25 /11.
- Strong-Drive® SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
- Bolts and Strong-Drive® SDS Heavy-Duty Connector screws may be installed through metal truss connector plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2014, Sections 7.5.3.4 and 8.9.2 are met.
- Wind (160) is a download rating.
- To achieve published loads, install bolts into the girder truss with the nut on the opposite side of the hanger with a standard-cut washer (except THGWVs). Standard-cut washers are required for THGBV and THGBHV.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
