About this detail

This drawing provides roof framing and sheathing layout instructions, detailing continuous sheathing edges at strapped sub-diaphragms, staggered sheathing placement, and edge nailing patterns. Steel ledger connections specify the use of Pneutek pins with continuous straps. A sub-purlin schedule lists rafter sizes, maximum spans, and hanger connections for wood members. Roof framing notes outline dead loads, live loads, uplift requirements, deflection criteria, and truss support specifications.

CONTINUOUS SHEATHING EDGES AT STRAPPED SUB-DIAPHRAGM SEE ROOF FRAMING FOR EXTENT STAGGERED SHEATHING EDGES, TYPICAL SKYLIGHT SHALL NOT INTERRUPT STRAPPED MEMBERS. OFFSET WALL TIES, STRAPS, & NAILING AS NEEDED, NOT EXCEEDING TYP SPACING EDGE NAILING EDGE MEMBER SEE DIAPHRAGM NAILING SCHEDULE FOR MIN WIDTH INTERMEDIATE NAILING (FIELD) CONT EDGE NAILING WALL PANEL STRAP SEE ROOF FRAMING PLAN FOR LOCATION AND DESIGNATION, TYP GRID (2) ROWS CONT EDGE NAILING FULL LENGTH OF GIRDER NAILER. (4 OR 6 LINES WHERE NAILING IS STAGGERED) POWDER DRIVEN PINS AT LEDGER AT BOUNDARY SPACING NAILING NOTES 1. ALL ROOF NAILINGS SHALL BE INSPECTED AND APPROVED BY INSPECTOR PRIOR TO COVERING BY ROOFING. 2. BOUNDARY NAILINGS ARE DEFINED AS NAILINGS AT LEDGERS, NAILERS OVER SHEAR WALLS AND MAJOR STRUT LINES. TRANSITIONS BETWEEN NAILING ZONES ARE NOT DEFINED AS BOUNDARY NAILING. 3. CONTINUOUS JOINT NAILING OCCURS AT STRAPPED MEMBERS AND TRUSS PURLINS. SEE DETAIL 1/- BELOW 4. FOR STEEL LEDGERS USE PNEUTEK PIN SDL45125 FOR 1/2" SHEATHING (SDL45138 FOR 5/8" SHEATHING) PER ESR-2902 WITH 18 GA x 1 1/2" x CONT STRAP (USE 18GA x 2" CONT STRAP FOR 3 ROWS OF NAILS).

DESIGN ROOF LOADS (UNO): 2. SEE DETAIL 1/SD3 FOR ADDITIONAL JOIST/GIRDER REINFORCING WHERE REQUIRED. 3. ALL TRUSS AND GIRDERS SHALL HAVE SJI STANDARD CAMBERS. 4. ROOF TRUSS MANUFACTURER SHALL SUBMIT TRUSS, PURLIN AND GIRDER CALCULATIONS AND KEY PLANS TO ENGINEER OF RECORD FOR REVIEW AND TO THE CITY FOR APPROVAL PRIOR TO FABRICATION. REFER TO SPRINKLER CONTRACTOR DRAWINGS FOR ALL SPRINKLER PIPE LOCATIONS, WEIGHT AND ALL ASSOCIATED SEISMIC BRACE LOADS. UPGRADE ALL ROOF TRUSSES AND GIRDERS FOR ALL MECHANICAL AND SPRINKLER LOADS AS SHOWN ON MECHANICAL AND SPRINKLER DRAWINGS. 5. ALL TRUSSES, PURLINS AND GIRDERS SHALL BE BRIDGED AND/OR BRACED ACCORDING TO MANUFACTURERS RECOMMENDATION. 6. TRUSS SEAT HEIGHT SHALL BE AS FOLLOWS (UNO): AT PURLIN = 3" AT GIRDERS = 7 1/2 7. ALL ROOF TRUSS PURLINS AND GIRDERS SHALL HAVE SEAT SLOPE ACCORDING TO ROOF ELEVATIONS. REFER TO ARCHITECTURAL DRAWINGS FOR ROOF ELEVATIONS. 8. DEFLECTION CRITERIA: LIVE LOAD DEFLECTION ≤ L/240 TOTAL LOAD DEFLECTION ≤ L/180 9. INDICATES BOTTOM OF SHEATHING ELEVATION. GENERAL CONTRACTOR SHALL VERIFY ALL ROOF ELEVATIONS WITH ARCH DWGS AND NOTIFY THE ARCHITECT AND OR ENGINEER IF ANY DISCREPANCIES ARISES PRIOR TO CONSTRUCTION. 10. SUB-PURLIN SCHEDULE: ALTERNATE USE ZMAX COATING WITH ELECTRO GALVANIZED SCREW SHANK NAILS. PROVIDE MINIMUM 2x6 NO.2 @ 24"OC AT ALL OFFICE AREAS. NOTE: PROVIDE 4x RAFTERS AT ALL STRAPPED MEMBERS AND AT SHEATHING EDGES WHERE REQUIRED PER NAILING AREA. 11. 2x SUB-PURLINS SHALL NOT BE USED TO SUPPORT ANY SPRINKLER OR TENANT IMPROVEMENT LOADS. 12.
