RIGGING SUPPORT IN THE TRUSSES

When I built the trusses last summer, I did not build in any triangulation. They were already very difficult to build {being 30 feet long & 18 in tall made it very difficult} I did not want it any harder. Also I could not have gotten them up into place if they were any larger. Remember, these are additional to what is already in place. I decided to get additional support for the new trusses by tying them into the existing trusses with rigging. By using 3/32 steel rope (1000 lbs break), 3/8 turnbuckles (1200 lbs break) 3/16 tubing and cable clamps. I used three sections of tubing on each support. I bent the tubing around the existing trusses near the top and under the new trusses in the middle of the truss. I threaded the steel rope thru the tubing and thru the eye bolt of the turnbuckles and clamped them. I did the same going under the truss. I did this for all ten trusses. took out all the slack in the steel rope before clamping them off. Then it's tighten the turnbuckles until there is no bounce in the truss. Worked out very nicely. Will work great for additional support for sheetrock and insulation loading. The pictures makes alot easier to understand
