The back storage addition to my new home has a post supporting the central beam that worries me. The post is out of alignment, with the bottom of the post about a half inch offset from the top. In addition, the post cap is far too small for the load it's carrying and is causing the wood above it to become noticeably compressed.
The plan is to support the beam (3x 2"x12"s nailed together, supported on both ends by 4 2"x6"s nailed together. Beam is warped slightly in the 13ft section due to the post initially being placed 15 feet from the right wall) above with two temporary jack posts while the old post is removed and for the week or two while the new pillar is curing. The new pillar is planned to be 12"x12" brick pillar filled with cement and an central threaded reinforcing rod that is secured into the slab. I was planning on using concrete brick instead of masonry brick for cost reasons.
I've tried searching for new metal lally columns in the Austin area, they simply aren't available.
Due to the beam being warped, I was planing to reinstall the old post that is removed with a new cap about 5 feet from the right wall to help reduce stress on the beam and eliminate the 13 ft stretch.
What would make good cap material for the brick pillar to distribute the load? I was thinking a single 2x12x12 with the wood grain perpendicular to the beam.
What would be the best way to lift the beam enough to remove the old post? Planning to get keep tightening jack posts up on either side of the lally until the girder is lifted the 1/4" or so and the lally is free.
Thanks in advance for any input!
