IUS/MIU I-Joist Hangers


Installation

View step-by-step installation instructions

The IUS is fully compatible with shallow flange I-joists.

I-joists with flange thicknesses between 1 1/8" and 1 1/2" achieve the full allowable table loads including uplift values and joist nails are not required. The IUS is a hybrid hanger that incorporates the advantages of the face mount and top mount hanger. Installation is fast with the Strong-Grip™ seat, easy-to-reach face nail locations and self-jigging locator tabs.

The MIU series hangers are designed for commercial and high load I-joist applications without requiring web stiffeners. The MIU features Positive Angle Nailing (PAN), which minimizes splitting of the flanges while permitting time-saving nailing from a better angle.

Refer to Joist Manufacturer's literature or appropriate Simpson Strong-Tie® Connector Selection Guide for actual joist sizes.

Material: See Face Mount Hanger tables.

IUS
(some IUS models have triangle holes in header flanges for Min/Max nailing)
U.S. Patent 6,523,321
The Strong-Grip™ seat secures I-joists in position without joist nails AVOID A MISINSTALLATION
Do not make your own holes. Do not nail the bottom flange.
IUS INSTALLATION SEQUENCE
Step 1
Attach the IUS to the header
Step 2
Slide the I-joist downward into the IUS until it rests above the large teardrop.
Step 3
Firmly push or snap I-joist fully into the seat of the IUS.

PREVENT ROTATION
Hangers provide some joist rotation resistance; however, additional lateral restraint may be required for deep joists.
No Web stiffener installed
Hanger side flange supports joist top flange.
Rotation Prevented by Web Stiffeners
Hanger height should be at least 60% of joist height
Rotation Prevented by Web Stiffeners
If hanger height is less than 60% of the joist height, add clips or blocking near the top.
Rotation Prevented by Lateral Flange Support
Side of hanger laterally support the top flange of the I-joist. No web stiffeners required!
POSITIVE ANGLE NAILING
Correct Nailing
Approx. 45° angle
Nail too long Nail at wrong angle
TOE-NAILING
Toe nailing causes squeaks and improper hanger installations. Do not toe nail I-joists before installing top flange or face mount hangers.


top Wood I-Joists:
 

Sloped Joists
For sloped joists up to 1/4:12 there is no reduction. For slopes greater than 1/4:12 see individual product pages or refer to technical bulletin T-SLOPEJST.

Multiple Joists
Multiple joists should be adequately connected together to act as one unit.

Fasteners
Use the correct nails. Wood may split if the nails are too large. Hanger nails into flanges should not exceed 10d common (0.148 dia.), no longer than 1 1/2". Nails into web stiffeners should not exceed 16d commons (0.162 dia.).

Eccentrically-Loaded I-Joists
Supporting a top flange hanger may require bottom flange restraining straps, blocking or directly-applied ceiling systems to prevent rotation at the hanger location.

Skewed Joists
Joists may be skewed up to 2 1/2 degrees in a non-skewed hanger without any load reduction. Refer to individual hanger descriptions for information allowing any further skew applications.

I-JOIST AS A HEADER INSTALLATIONS
 
  Face Mount Hanger Top Flange Hanger
 
 
When face mount hangers are attached to I-joist headers, backer blocks must be installed to provide a nailing surface for the hanger nails. The backer blocks should be installed on both sides of the web and attached together with a minimum of 10-10d nails. The hanger nails should extend through the web. Contact the I-Joist manufacture for additional design considerations.
When top flange hangers are attached to I-joist headers, a backer block must be installed to prevent the top flange from rotating under load. The backer blocks should be installed with a minimum of 10-10d nails clinched. Check with the joist manufacturer for additional design considerations.
