GENERAL NOTES AND INFORMATION JOIST FRAMING IS UNSTABLE UNTIL BRACED LATERALLY. BRACING INCLUDES: END RESTRAINTS TEMPORARY LATERAL BRACING HANGERS BLOCKING SHEATHING IF BRACING IS CUT OR ALTERED CONTACT YOUR SPACEJOIST TE REPRESENTATIVE.

Accidents can be reduced if the following guidelines are practiced. 1. Attach temporary 1x4 (minimum) lateral bracing to each SpaceJoist TE truss during installation. Lateral bracing must be securely anchored to a braced end wall or other rigid support prior to truss installation to prevent truss rollover. 2. Solid end bracings, such as a braced end wall or an existing deck, must be established at the ends of each span. This can also be accomplished by temporary or permanent deck (sheathing) nailed to the first four feet of joist at the end of the span. 3. All blocking, reinforcements, hangers, and rim boards at the end supports of the SpaceJoist TE and sheathing must be completely installed and properly nailed prior to loading the trusses. 1.0 1/2" gypsum board 2.2 5/8" gypsum board 8.0 5. Ends of cantilevers require rim board attachment on both the top and bottom flanges. 6. See "BCSI 1-03 Guide to Good Practice for Handling, Installing & Bracing of Metal Plate Connected Wood Trusses, BCSI-B1 Summary Sheet and the BCSI Summary Sheet-Series" by the Truss Plate Institute and the Wood Truss Council of America. 2.8 Plaster (1" thick) 4. Sheathing must be fully attached to each SpaceJoist TE before loading the system. 6.5 Acoustical fiber board Ceilings WARNING NOTES 0.1 Hardwood (nominal 1") Roll or Batt Insulation Do not stack building materials on unsheathed SpaceJoist TE. Stack building materials only over beams or bearing walls. See Note 4 below. 2.0 3/4" OSB Sheathing 1.5 5/8" plywood Do not allow workers to walk on SpaceJoist TE until braced or injury may result. See Notes 1, 2, and 3 below. Failure to comply with these recommendations may cause serious injury, structural malfunction and/or collapse. 9
