This is an update to my previous post "Lentil Beam Above Garage is
Bending". Since then, I've learn the correct spelling of lintel. I
had some repairs done and still have a concern that it's not
completely fixed. So, here's an overview of the issue and i'd
appreciate any thoughts/comments/suggestions.
Problem: Started with a crack in the brick veneer (gable) above the
garage door. After having a structural engineer look at the problem,
he determined that the lintel was torking out and working away from
the header, causing the bricks to actually move out a few mm and
resulting in the large, growing crack. He figured that the builder
did not put in lag bolts to attach the lintel to the header.
Fix:He recommended two things. First, to take some bricks out (every
6th brick) and go in and re-attach the lintel to the header with lag
bolts. Second, he recommended building a secondary header up in the
attic, behind the gable, with 1 1/8 inch plywood to attach all the
studs to one another and take the pressure off of the center studs
(where it was bending most) and distribute the weight to all the studs
behind the gable. So, with a masonry's help, we jacked the lentil
back up, and made the two recommended fixes. There actually were
bolts attaching the lintel to the header, but they were relatively
small and the holes were drilled below the centerline of the 3" angle
iron. We put in much larger bolts nearer the top of the angle iron
(lintel). When we let the jack out, the lintel barely moved.
My concern: Is that the brick veneer is not securely tied to the
studs, therefore the work done in the attic of attaching all the studs
to one another with overlapping plywood really won't affect the
movement of the brick. Is that possible? Does the plywood work
somehow increase the strength of my header? Any other issues/concerns
you may have?
