Lolly / lally columns, where to buy?
Lolly / lally columns, where to buy?
(OP)
So I helped my inlaws designing extra support for their flat roof garage. Their roof was built with 2x10 @ 12" o.c. long ways!!! (25 ft) yikes! So I am telling them to get (3)-1 3/4x14 LVL and break the span in half and maybe use lolly column on ea. side and bear it on existing slab & footing. Where can I buy lolly columns? I want one with saddle at least 5 1/4" wide so I can brace the LVL. I googled it and had no luck.

I would think that all you need would be an adjustable jack post pipe column that you can purchase at almost any local home center. Your other option is to have a structural steel fabricator fab up a pipe column with a steel saddle to your specifications.

Is the saddle and lag screw from the side just to consider it braced at the ends? If so, can you just install a Simpson A21 or something similar from the 2x10's bearing on the LVL to the top of the LVL?

seriously, the "lally columns" i've seen in residental construction are the adjustable jack post pipe columns (calc a 3.5" Sch 40) like jike is talking about. The fabrication your looking for is either standard or it should be because it's designed a lot.
If you go with adjustable columns, i'd look into anchoring the threads with concrete at the base.

Now that I think about it more, I am not sure the saddle with a lag screw/bolt through the LVL will brace the LVL without something from the 2x10 to the LVL unless you have a different means of bracing the column.
I agree that the saddle with lag is probably the way to do, but still use something to brace the top of the LVL to the 2x10's.

Also see article in "Structure" magazine Sept 2004, page 16, has load tables for Lally posts.

I just had a home appraiser make a big stink because someone did what you are proposing and did not put a footing under the column. The sale of the house now depends on the owner fixing his DIY screw adjustable column.
