1、Designation: F 2536 06bStandard Guide forInstalling Plastic DWV Piping Suspended from On-GradeSlabs1This standard is issued under the fixed designation F 2536; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi
2、on. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.Note Sections 2 and 5 were revised from the previous 2006a version and the year date was changed on Sept. 29, 2006.1. Scope1.1 This guide pr
3、ovides procedures for the installation ofDWV piping in buildings that are built where soil conditionsrequire the use of pier or piling supported grade beamconstruction or in filled ground where the soil compaction isless than 95 %. These procedures are intended to ensure thatthe DWV piping suspended
4、 from the on grade concrete slabs isnot damaged or destroyed by movement of the soil or fill underthe slab after the building is completed and occupied.1.2 In this type of construction, the area within the gradebeams is filled with soil up to a level that allows the concreteslab to be poured directl
5、y on the fill without a supporting form.In this process the sanitary waste piping is installed bytrenching into the fill, and then putting hangers with supportrods on the pipes as they are installed. The hanger rodsextending upward must be long enough so that the top of therod will be embedded in an
6、d anchored in the concrete.1.3 The hanger rods are intended to provide adequatestrength and corrosion resistance to assure long term service.1.4 The details of installation are intended to ensure that therods remain vertical, that they extend into the concrete anadequate amount and that the upper en
7、ds are terminated so thatthey have adequate “pull out”strength.1.5 The details of backfill are intended to limit or minimizethe loads on the a suspended piping. These loads result fromconsolidation or movement of the soil/fill beneath the slab.1.6 This standard does not purport to address all of the
8、safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
