Engineered repair?


Recommended Posts

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

I've seen it done several times to support sagging beams in accessory structures, never in a house and never on a rafter. 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.

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.

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.

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.

Well, hell! Where's that "feeling foolish" icon at.

At the left of the composition box. Click on the "show entire smile list" selection.

Which one do you want?
