Fire Wall Hangers for Plated Truss

This product's information may differ depending on the category of use. You are currently viewing details related to Fire Wall Hangers for Plated Truss. You can also view product information related to the categories of: Fire Wall Hangers for Engineered Wood, Fire Wall Hangers for Solid Sawn Lumber

The DU/DHU face-mount and the DHUTF top-mount hangers are designed to carry joist floor loads to a wood stud wall through two layers of 5/8" gypsum board (drywall). These hangers install after the drywall is in place. The hangers come in sizes that accommodate most joists used in multi-family construction including I-joists and trusses.

Material

  • DU — 14 gauge; DHU and DHUTF — 12 gauge

Finish

  • Galvanized

Installation

  • Use all specified fasteners; see General Notes.
  • Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws are provided with the hanger.
  • Drywall is installed first.
  • DU and DHU are mounted with top of hanger flush with top of wall and tight to the drywall.
  • Wall top plates must be restrained to prevent rotation. Use a stud plate tie connector at the back of each stud or provide equivalent restraint by another method as determined by Designer.
  • Upper plate splices must occur at a stud location.

Options

  • The DHU may be ordered with one flange concealed for widths at least 2 1/2" wide; specify which flange when ordering. Use 74% of the table downloads and 100% of table uplift loads.
  • The DHU/DHUTF may be ordered skewed up to 45°. Use 75% of the table downloads and 50% of table uplift loads.

Two-Hour, Fire-Rated Wall

  • Simpson Strong-Tie has completed ASTM E814 standard testing at an accredited laboratory. The use of the DU/DHU/DHUTF hangers does not reduce the two-hour, fire wall assembly rating. The hangers tested provide an F (flame) and T (temperature) rating.

Load Tables

  1. Loads assume 5/8" type X drywall attached per IBC. Wall assembly must consist of minimum two 2x4 plate members with studs spaced not more than 16" o.c. For alternate solutions to mounting over single layer of drywall, refer to the technical bulletin T-C-TFWALL16.
  2. Hangers spaced closer than 16" o.c. shall reduce capacity proportionately.
  3. Triangle nail holes may be filled with (4) additional 10d x 1 1/2" to achieve an Allowable Uplift Load of 750 lb.
  4. DF carried members with minimum 1 1/2" x 2 1/2" solid sawn chord dimension may increase Allowable Uplift Load to 170 lbs.
  5. Allowable downloads may be increased to 1,885 lb. for DF/SP and 1,585 lb. for SPF/HF using the DHU3.56/24 or DHUTF3.56/24 models.
  6. For DHU/DHUTF two-sided (back-to-back) application on a 2x6 wall, use 1,200 lb. allowable download for DF/SP plates and use 1,005 lb. for SPF/HF plates.
  7. For DU two-sided (back-to-back) application on a 2x6 wall use 1,075 lb. allowable download for DF/SP plates and use 880 lb. for SPF/HF plates.
  8. For installations of two layers of gypsum wall board over 5/8" maximum wood structural panel, the DHU/DHUTF has a capacity of 1,975 lb. allowable download for DF/SP plates and has a capacity of 1,660 lb. for SPF/HF plates.
  9. For the DU, if a 5/8" structural wood panel is used between the drywall and studs, use 1,110 lb. allowable download for DF/SP plates and use 880 lb. for SPF/HF plates.
