Hung Lintel - Double Wythe Brick
Hung Lintel - Double Wythe Brick
(OP)
Has anyone dealt with this detail before? See attached section (architectural). I have a +/- 14ft. opening with a double wythe brick masonry wall. This is a steel frame building - but the arch. wants a double wythe facade (and they won't give up on that idea). They are currently showing a loose lintel in the attached section but that won't work so I need to hang it.
The first thought is to change the beam to a tube and do a hung lintel from the steel - but I'm going to need a relatively thick plate (bent plate?) to carry that brick. The o.f. of brick is about 12in. from c.l. of steel and it's carrrying about 15 feet vertically with a few punched openings.
Has anyone done a detail for this and have anything clever?

If not, hang some 1/4" steel plates from the steel beam and extend a horizontal plate from the inside of the stud wall to the outside of the brick.

Is there a reason for the double wythe that is not showing above or below the detail? Is the interior portion of the double wythe bearing at the ends of the opening?
Without further information, just recommend that the interior bricks of the double wythe be made of styrofoam, and specify a normal connection.

I would look at making the brick carry itself for gravity loading. By building in galavanized reinforcing, you should be able to create a reinforced masonry beam which will do the job.

1 It looks like the double wythe is driven by the Bluestone sill, which appears to be supporting the window above. Is this the case?
2. Is there a vertical shrinkage allowance for the wood/brick combination at the topside of the Bluestone Sill? If not, where is it?

BA - I think I will do what you recommend and forget trying to support it from the frame. I was originally considering this option but it seemed like a waste since I'll have to deal with tying it back somehow for wind. Doesn't seem very elegant but better than hanging it from the beam I guess.
RE: Hung Lintel - Double Wythe Brick
And how to compensate for the vertical shrinkage issue from floor to floor? - probably in the order of 1/8" to 1'4", depending on the wood species and type used.

But I like BA's suggestion.
