SCB/MSCB Bypass Framing Slide-Clip Connector

Transcription

1 Deflection Connectors Connectors for Cold-Formed Steel Construction SCB/MSCB Bypass Framing Slide-Clip Connector 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 SCB/MSCB slide-clip connectors are high-performance connectors for bypass framing applications designed to reduce design time and overall installed cost. Various anchorage methods have been tested, and the resulting allowable loads eliminate the need to design connector anchorage. The SCB/MSCB can accommodate applications that typically require two parts with a single connector, reducing material and labor cost. These connectors are manufactured in five different lengths to accommodate a variety of stand-off conditions and steel-stud sizes. Features: Provides a full 1" of both upward and downward movement The precision-manufactured shouldered screws provided with the SCB/MSCB connector are designed to prevent overdriving and to ensure the clip functions properly Strategically placed stiffeners, embossments and anchor holes maximize connector performance No-Equal stamps mark the center of the slots to help ensure correct shouldered-screw placement Material: SCB 54 mil (16 ga.); MSCB 68 mil (14 ga.) Finish: Galvanized (G90) Installation: Use the specified type and number of anchors. Use the specified number of XLSH4B1414 #14 shouldered screws (included). Install shouldered screws in the slots adjacent to the No-Equal stamp. Use a maximum of one screw per slot. Codes: See p. 11 for Code Reference Key Chart Ordering Information: SCB4.5-KT contains: 5 connectors (55) XLSH4B1414 #14 shouldered screws SCB45.5-KT, MSCB45.5-KT, SCB47.5-KT, MSCB47.5-KT, SCB49.5-KT, and SCB411.5-KT contain: 5 connectors (8) XLSH4B1414 #14 shouldered screws Note: Replacement #14 shouldered screws for SCB/MSCB connectors are XLSH4B1414-RP8 SCB4.5 SCB47.5 (MSCB47.5 similar) SCB49.5 SCB411.5 U.S. Patent 8,555,59 ¾" XLSH4B1414 #14 Shouldered Screw SCB45.5 (MSCB45.5 similar) 0.4" C-CF SIMPSON STRONG-TIE COMPANY INC.

When the SCB or MSCB connector is used with two shouldered screws, the screws may be installed in any two slots.. Allowable loads are based on clips installed with (4) #1 14 screws in the anchor leg. For other anchorage installations, the capacity of the connection system will be the minimum of the tabulated value and the allowable load from the SCB/MSCB Allowable Anchorage s table on p. 8.. Anchorage to the supporting structure using welds or a minimum of () #1 4 self-drilling screws is required. 4. Allowable loads are based on in-plane loads applied to the stud fasteners that are nearest the support with complete rotational restraint at the studs.

Allowable loads for #1 4 self-drilling screws and PDPAT powder-actuated fasteners are based on installation in minimum structural steel with F y = 6 ksi. PDPAT values are also provided for A57 steel. Values listed above maybe used where other thicknesses of steel are encountered provided that the fastener has equal or better tested values into thicker steel (see p. 16). It is the responsibility of the Designer to select the proper length fasteners based on the steel thickness installation. 4. For screw fastener installation into steel backed by concrete, predrilling of both the steel and the concrete is suggested. For predrilling use a maximum /16"-diameter drill bit.

4 Does your project require DoD-compliant blast design? Although Allowable Design (ASD) is widely used by Designers of Cold-Formed Steel (CFS) construction, some projects require additional connector limit states beyond the typical ASD values that are normally tabulated in our load tables. For example, many Department of Defense (DoD) projects require blast design of exterior wall framing and connections. Such projects may require the strength or nominal strength for the blast calculations. For a more comprehensive background on blast design please reference the Structural Engineering Blog at seblog.strongtie.com and enter the search term DoD. Not finding what you need? Please contact.
