Floor sheathing is to be 3/4"minimum thick OSB/plywood installed in a staggered pattern. Nail to floor members with 0.131"diameter x <br /> 3"long nails at 6"o.c.at all panel edges/perimeter and 12"o.c.at all intermediate supports or an approved equivalent. <br /> 2. Blocking shown maV be replaced with pre-manufactured blocking provided it can resist at least 1500 pounds of lateral compression. <br /> 3. Toe nail blocking members in place as required for stabiltV. <br /> 4. Bays containing blocking do not need to be directly next to the wall or each other provided 2x4 spacer blocking is installed between <br /> them as shown. Toe nail spacers in place as reauired. <br /> 5. OSB/plywood blocking may contain 4"diameter maximum holes if required for electrical/plumbing. Provide at least 3"edge clearance <br /> for all holes. <br /> 6. All nails are to be spaced in members such that splitting does not occur. <br /> 7. Foundation wall is to be per Code by others. <br /> 8. Do not cut rim truss bottom chord for any reason. <br /> Oswell Engineering and Consulting,L.L.C. 1901 E Hennepin Ave,#201 . <br /> Project Name: 2014 BAM Top of Foundation Support Guide Minneapolis,MN 55413 <br /> Description: Non-Bearing Wall Bottom Chord Bearing Truss Blocking Detail(NOT TO SCALE) Phone:612-7204639 x a <br /> Project# 14.007 Fax:612-886-2966 +r <br /> Client Name: Builder's Association of Minnesota(BAM) www.oswellec.com <br /> Page S5 of S6 t' , S• <br /> 1/1/2014 <br />
