Standard Specification for Driven Steel Post Drive Anchor System
ABSTRACT
This specification establishes the material requirements and installation procedures for driven steel post drive anchor systems. It provides an alternative to the use of concrete footings for the purpose of installing steel post frameworks to support chain link, expanded metal, welded wire mesh, wood, ornamental, rigid PVC, and composite fence. The drive anchor clamp bracket—the pressed steel fitting that secures the drive anchors to the post—shall be pressed steel, minimum of 11 ga. x 1 in. wide, minimum 1.2 oz/ft² hot dipped zinc coating. The bracket shall be secured using 3/8 in. diameter bolts. Industrial/commercial applications require all driven steel anchors, including round or square sections, to have equal or greater strength characteristics as the historical 1 1/2 in. x 1 1/2 in. x 1/8 in. steel angle irons. Whichever shape is chosen, the yield strength shall be 35,000 psi, maximum bending moment 6,462 lb/in., minimum 1.2 oz/ft² zinc coating, and gripping surface area 3 in.².
This specification also includes post-anchoring system guidelines for commercial use.
SCOPE
1.1 This standard provides an alternative to the use of concrete footings for the purpose of installing steel post framework to support chain link, expanded metal, welded wire mesh, wood, ornamental, rigid PVC, and composite fence.
1.2 This standard is not intended to include all methods available to support fence post framework.
1.3 This standard does not intend to preclude any practice that has proven equal to or given better performance under varying conditions such as location, weather, or intended use.
1.4 The values stated in inch-pound units are to be regarded as standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
