2 TELEPHONE CONDUIT SYSTEM PVC CONDUIT STEEL BEAM/GIRDER SPANS NOTES TO DESIGNER: Standard is for use with: PVC conduit Steel beam/girder spans Show conduit formation on transverse section sheet and indicate number of conduits (e.g mm dia. telephone conduits). Show dimension from bottom of top flange (top of web) to support angle at the beam/girder the dimension is set on transverse section sheet. When setting the dimension allow for a minimum of 25 mm (50 to 75 mm preferred) clearance to diaphragms, cross frames etc. Normally the critical clearances are at the ends of spans (at supports). Indicate location of centerline of telephone conduits on framing plan (e.g., centerline of mm dia. telephone conduits). Do not show hanger spacing on framing plan. ADD THE FOLLOWING NOTES, DIMENSIONS, DETAILS, ETC. TO STANDARD: TYPICAL SUPPORT DETAIL: Enter dimension from bottom of top flange to L 127 x 76 x 9.5 support. This must agree with dimension set on transverse section sheet. STANDARD MBTC-4: NOTES TO DESIGNER VOL. V - PART 3M DATE: 01Jul02 SHEET 2 of 2 FILE NO. MBTC-4
