Wasden Posted March 13, 2013 Report Share Posted March 13, 2013 Sorry I don't have the photo but I sketched this. While starting my inspection I noticed a drooping roof plane. The seller made it difficult for me to get to the hatch to the attic. I'm glad I took the time to check it out. It looked like the three rafters were cracked and this angle iron bracket with a strut welded at 90 degree with cables attached to put upward pressure on the rafter. Anyone see anything like it before? Thanks, Steve Click to Enlarge 31 KB Link to comment Share on other sites More sharing options...

As long as the cable connection points are solid, it'll work just fine. Seems like an awful lot of trouble to go through when you could just sister a new rafter next to the old.

AHI in AR Posted March 13, 2013 Report Share Posted March 13, 2013 As Jim said, it will work just fine if the conditions he stated are met. They've built a truss. And not to put too fine a point on it, but it doesn't really put "upward" pressure on the rafter; it provides resistance to deflection at the center of the rafter.

Marc Posted March 13, 2013 Report Share Posted March 13, 2013 The cables don't provide any uplift capacity. Uplift capacity is needed to resist the effects of wind on the leeward side of the roof. Marc Link to comment Share on other sites More sharing options...
John Kogel Posted March 13, 2013 Report Share Posted March 13, 2013 It is not a typical engineered rafter repair, so I would be inclined to call for some paperwork signed by the 'engineer'. When he can't produce this paper, we can get a real engineer to draw up a proper repair, or simply get an experienced builder to sister the rafters. With a slight bit of movement, that cable can just pop off the brace and become useless. I'll search for the pics. Click to Enlarge 30.62 KB Click to Enlarge 46.3 KB One cable had popped off. A couple of years later, I returned to inspect another unit and found that the management had repaired this. It may been nudged by a truck.

Chad Fabry Posted March 13, 2013 Report Share Posted March 13, 2013 I did that to my barn's central support beam. The roof was down, the walls were spreading and the beam was sagging. I ran the cable through the walls and under the beam, tightened the turnbuckles and now everything is where it's supposed to be. Link to comment Share on other sites More sharing options...
Wasden Posted March 13, 2013 Author Report Share Posted March 13, 2013 Thank you everyone. I suspect that it didn't work too well since I saw the flaw on the exterior walk. Sure glad I took the extra effort to look into the attic. Link to comment Share on other sites More sharing options...

John Kogel Posted March 13, 2013 Report Share Posted March 13, 2013 "Extra" effort to look in the attic? Really? Yeah, I did a double take, and it seems he had to climb over or move obstacles placed by the seller to block access to the hatch. Link to comment Share on other sites More sharing options...
Erby Posted March 14, 2013 Report Share Posted March 14, 2013 Well, hell! Where's that "feeling foolish" icon at. Now I understand the extra effort with the seller placing obstacles in the way to the access. Guess I should have read the whole thread again.
