12、T STEEL WALL FRAMING COMPONENTS 1. SCOPE 1.1 This standard provides criteria, including dimensions, material and structural requirements for lightweight steel wall framing components designed for use in: a. Non-loadbearing applications, typically the framing for interior partitions including studs w
13、ith no axial load other than self weight and the weight of attached finishes and no lateral load other than nominal interior pressure differences. b. Wind loadbearing applications, typically the framing for exterior wails including studs subject to lateral loads due to wind but no axial load other t
14、han self weight and the weight of attached finishes. c. Axial loadbearing applications, typically the framing for interior or exterior walls including studs subject to axial loads in addition to those due to self weight and the weight of attached finishes. The axial loads may act in combination with
15、 lateral loads due to nominal interior pressure differences or wind. 1.2 The components covered in this standard include studs, tracks and rigid furring channels. This standard does not cover other cold formed steel framing components such as joists, resilient furring channels, girts or purlins. 1.3
16、 This standard is intended to establish and encourage the production and use of standardized products. Deviations from the standard dimensions are acceptable, except for the stud depth (web), provided the product complies with all other provisions of this standard. 1.4 The testing and evaluation of
17、a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establi
18、sh appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. 2.

31、d from corrosion by a zinc coating at least meeting the requirements of ASTM A 591/A 591M, Class B. Other coatings providing equivalent or better corrosion protection may be used. For exterior2 wall applications the steel shall be protected from corrosion by a zinc coating at least equal to the Zl80
32、 designation of ASTM A 653lA 653M. Other coatings providing equivalent or better corrosion protection may be used. Aluminum-zinc alloy coated steel components conforming to ASTM A 792lA 792M are not currently recommended for applications in contact with fresh concrete. The track (runner) shall be fo
33、rmed in a U-shaped configuration having depths compatible with those of the studs of the same nominal size. The tracks (runners) shall be designed such that when the studs are placed in both the top and the bottom tracks (runners) they shall be held by friction. The thickness of tracks (runners) sha

This tolerance shal
35、l be pro-rated for other lengths. The studs, runners, and rigid furring channels shall be manufactured with a minimum of burrs and sharp edges. An interior wall is a wail that is not exposed to the outdoor environment on either side. *An exterior wall is a wall that is exposed to the outdoor environ
36、ment on one side and to the interior building environment on the other. 4 CANtCGSB-7.1-98 Copyright Canadian General Standards Board Provided by IHS under license with CGSBNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Sweep Camber f m p !
