If the truss bundle is to be stored for more Specify it with a bevel at the top so you get good edge nailing. They will build the block to resist the load. By using longer OSB panels such as TallWall or Windstorm to cover the entire wall height and the raised heel, you can eliminate expensive blocking, while providing a continuous load path and lateral stability. While, we don't commonly work on high heel trusses, when we have, we specify to either provide full-height 2x blocking, pre-manufactured truss blocking or to sheath panels between trusses to form mini shearwalls. Terry Malone agrees with them. Default value is "NO". This is the adopted residential code throughout the US, I think, in localities large and small. "SIMPSON" LS50 CLIP TO CONNECT BLOCKING TO TOP PLATE (1 per truss space) 6. Nail it to the bottom of the rafter on the second truss to hold them parallel to each … Truss to Heel Leg Connection I would think that raised heel would need to be engineered because it converts the vertical load to a shear load between the truss and the vertical 2 X 6 legs; due to the inclined contact between the top of the legs and the bottom of the top chords. I long to see one in real life. £9.90 postage. Registration on or use of this site constitutes acceptance of our Privacy Policy. Default value is "VERTICAL". The problem with my first shear panel option shown is that the contractor would have to notch around the top chords of the truss, too much hassle and then you are still left with having to punch holes in the sheathing for the ventilation and its hard to control how big these holes may be so the shear panels are probably compromised. I use the shear panel option between trusses on all my wood projects. :R�a/��wS5J��qsR��2�(O�&��Z܀�ѝO�M���p��z. EXTERIOR WALL; ROOF SHEATHING MUST CONNECT VIA THIS BOX BLOCK DETAIL 7.

If the truss bundle is to be stored for more Specify it with a bevel at the top so you get good edge nailing. They will build the block to resist the load. By using longer OSB panels such as TallWall or Windstorm to cover the entire wall height and the raised heel, you can eliminate expensive blocking, while providing a continuous load path and lateral stability. While, we don't commonly work on high heel trusses, when we have, we specify to either provide full-height 2x blocking, pre-manufactured truss blocking or to sheath panels between trusses to form mini shearwalls. Terry Malone agrees with them. Default value is "NO". This is the adopted residential code throughout the US, I think, in localities large and small. "SIMPSON" LS50 CLIP TO CONNECT BLOCKING TO TOP PLATE (1 per truss space) 6. Nail it to the bottom of the rafter on the second truss to hold them parallel to each … Truss to Heel Leg Connection I would think that raised heel would need to be engineered because it converts the vertical load to a shear load between the truss and the vertical 2 X 6 legs; due to the inclined contact between the top of the legs and the bottom of the top chords. I long to see one in real life. £9.90 postage. Registration on or use of this site constitutes acceptance of our Privacy Policy. Default value is "VERTICAL". The problem with my first shear panel option shown is that the contractor would have to notch around the top chords of the truss, too much hassle and then you are still left with having to punch holes in the sheathing for the ventilation and its hard to control how big these holes may be so the shear panels are probably compromised.

If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it. Building codes require extensive blocking on raised-heel trusses higher than 15 ¼ inches to prevent uplift during inclement weather and create a stable structure. I'm quite impressed that others are getting the little shear panels though. Terry Malone agrees with them.
