GENERAL CONNECTOR INSTALLATION

Transcription

1 GENERAL CONNECTOR INSTALLATION TOP FLANGE HANGERS PREVENT ROTATION No Rotation Resistance Lack of web stiffeners combined with short hanger allows unwanted rotation. Flush Framing Top flange configuration and thickness of top flange need to be considered for flush frame conditions. Rotation Prevented by Web Stiffeners Hanger height should be at least 60% of joist height. Hanger Over-Spread If the hanger is overspread, it can raise the I-joist above the header and may cause uneven surfaces and squeaky floors. Rotation Prevented by Web Stiffeners If hanger height is less than 60% of the joist height, add clips or blocking near the top. Hanger Not Plumb A hanger kickedout from the header can cause uneven surfaces and squeaky floors. Hangers provide some joist rotation resistance; however, additional lateral restraint may be required for deep joists. Rotation Prevented by Lateral Flange Support Side of hanger laterally support the top flange of the I-joist. No web stiffeners required! WOOD NAILERS Correct Attachment TOE-NAILING Nailer Too Wide The loading may cause cross-grain bending. As a general rule, the maximum allowable overhang is 1 4", depending on nailer thickness. Nailer Too Narrow Nailer should be full width. POSITIVE ANGLE NAILING Nailer Too Thin or the wrong hanger for the application. 98 Toe nailing causes squeaks and improper hanger installations. Do not toe nail I-joists before installing top flange or face mount hangers. Correct Nailing Approx. 45 o angle Nail too long Nail at wrong angle

2 GENERAL CONNECTOR INSTALLATION 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 (see page 232 for details). 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 s may be skewed up to 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- manufacturer 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. CSC Ceiling Support Clip /FSS Furring Stabilizer Strap Provides 1" separation between the furring channel and joist to allow for the use of Thermafiber insulation and the attachment of the furring channel to all joists. Provides an efficient sound barrier, and a one hour U.L. listed fire rating. UL Listed. See Underwriters Laboratory, Inc. Design No. L530 for USG gypsum board and Weyerhaeuser/TJI joists. Check ICC-ES reports for individual I-joist manufacturer approvals. MATERIAL: 24 gauge (minimum) FINISH: Galvanized INSTALLATION: For CSC use 1-8dx1 1 2 nail. For FSS use #8 self-tapping steel screw (not provided) into channel, twist 90, bend upward and fasten to the side of joist bottom flange with screw or nail.

3 IUS/MIU I- Hangers This product is preferable to similar connectors because of a) easier installation, b) higher loads, c) lower installed cost, or a combination of these features. 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 nails 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 Manufacturer s literature or appropriate Simpson Strong-Tie Connector Selection Guide for actual joist sizes. MATERIAL: See table page FINISH: Galvanized UPLIFT LOADS uplift. Properly attached web stiffeners are required. 1 2" joist nails for a total uplift load of 975 lbs.

T-RIMBDHGR (see page 232 for details). sections can be used with the installation of 2-10dx1 1 2" nails into the optional triangle joist nails. the joist top flange is laterally supported by the sides of the hanger. I-joist manufacturers may require web stiffeners. OPTIONS: These hangers cannot be modified. However, these models will normally accommodate a skew of up to 5. For sloped joists up to 1 4:12 there is no reduction, between 1 4:12 and up to 1 2:12, tests show a 10% reduction in ultimate hanger strength. Local crushing of the bottom flange or excessive deflection may be limiting; check with joist manufacturer for specific limitations on bearing of this type.

11 TOP FLANGE HANGERS ITS/MIT/HIT Engineered Wood Products Hangers This product is preferable to similar connectors because of a) easier installation, b) higher loads, c) lower installed cost, or a combination of these features. 2" Funnel Flange " A dedicated range of Top Flange I-joist hangers meeting the unique needs of I-joists while offering superior performance and ease of installation. ITS The innovative ITS sets a new standard for engineered wood top flange hangers. The ITS installs faster and uses fewer nails than any other EWP top flange hanger. The new Strong-Grip seat and Funnel Flange features allow standard joist installation without requiring joist nails resulting in the lowest installed cost. The Strong-Grip seat firmly secures I-joists with flange thicknesses from 1 1 8" to 1 1 2". MIT/HIT - Patented Positive Angle Nailing (PAN) PAN is specifically designed for I-joists when used with the MIT or HIT. With PAN, the nail hole material is not removed, but is formed to channel and confine the path of the nail at approximately 45. PAN minimizes splitting of the flanges while permitting time-saving nailing from a better angle. See Top Flange tables on pages Refer to Manufacturer s literature or appropriate Simpson Strong-Tie Connector Selection Guide for actual joist sizes. MATERIAL: ITS 18 gauge; MIT, HIT 16 gauge FINISH: Galvanized INSTALLATION: can take the required fasteners specified in the table. See product specific installation drawings pages ITS no joist nailing required for standard I-joist installation without web stiffeners. When supporting I-joists with web stiffeners or rectangular SCL member 2-10dx1 1 2" must be installed into optional triangle joist nail holes for standard installation values. ITS optional triangle nail holes may be used for additional load. See allowable load tables. Refer to technical bulletin T-OPTUPLIFT for additional options (see page 231 for details). MIT optional triangle nail holes may be used for increased uplift capacity. See Optional Nailing For Increased table. HIT closed PAN nail holes may be used for increased uplift capacity. See Optional Nailing For Increased table. 1 4:12 there is no reduction, between 1 4:12 and up to 1 2:12, tests show a 10% reduction in ultimate hanger strength. Local crushing of the bottom flange or excessive deflection may be limiting; check with joist manufacturer for specific limitations on bearing of this type. ALLOWABLE LOADS: ITS, MIT and HIT hangers have locations for optional nails if additional uplift is needed. Optional uplift nailing requires the addition of properly-secured web stiffeners. See the load tables for minimum required fasteners and allowable uplift loads. OPTIONS: modified. However these models will normally accommodate a skew of up to 5.
