Install with crown edges up. Bear ends minimum 1 Yz" (3" on masonry). Provide solid blocking of same section size as joist at ends ofjoist and for bridging as follows, unless otherwise shown: Span to 10 feet, one row mid-span; spans to 20 feet, two rows at third points' spans to 30 feet, rows of bridging S feet maximum distance apart. Pre-manufactured metal or lx3 wood cross bridging may be substituted of solid bIidging on concealed work. Notch no more than 111 0 the depth of the joist, not in the middle third. Bore holes no more than 114: depth of joist, minimum 2: from top or bottom ofjoist. Provide double joist under all partitions running parallel to joists.
PLYWOOD SHEATHING & ORIENTED STRAND BOARD (OSB)
Place with face grain perpendicular to supports. Stagger joints and locate over eenter
of framing. Allow 1116" between edge joints and liS" between side joints to allow for expansion and contraction. Unless otherwise called for on the Drawings, support all edges perpendicular to framing by use oflumber blocking and nail 6 " on center along all edges, and 12" on center at intermediate supports with 8d nails.
A. Use only common wire nails or spikes on the dimension shown on the Nailing Schedule, except where otherwise called for on the Drawings.
B. For conditions not covered in the Nailing Schedule, provide penetration into the piece receiving the point of not less than Yz the length of the nail or spike, provided, however, that 16d nails may be used to connect two pieces of 2 inch nominal thickness.
C. Do all nailing without splitting wood. Pre-bore as required. Replace all split members.
Unless otherwise indicated on the Drawings or required by pertinent codes and regulations, provide at least the following nailing:
Blocking to joist bearing: two 10d toenailed each side.
Blocking to joist or studs: two 10d toenailed each side.
Bridging to joist: two Sd toenailed.
Built-up beams 8" or less in depth: 16d @ 24" on center, top and bottom
