RE: Precast Lintels

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I detail an oversized vertical hole near the end of the precast lintel.  The wall reinforcement under and over the lintel is offset from this hole.  A dowel is put thru the hole in the precast and is grouted solid.  It is also lap spliced with the wall reinforcement.

Subject: Precast Lintels

For cast-in-place lintels (either U-block or formed), the vertical reinforcing at the edges of the opening can be extended directly through the lintel.
 
But how is the vertical reinforing normally placed when a precast lintel is used?  It seems to me that the vertical reinforcing at the edges of the opening would have to terminate at the bottom & top of the lintel and then a full height bar could be placed in the adjoining cell.  Or is the non-continuous bar even used?
 
Is there a better way?
