I am new to this forum and look forward to interacting with you. I designed a 30' x 4' bridge that is using 6 x 6 posts and beams made from 3) 2 x 12's sandwiched together. I am looking for brackets that will encapsulate the 6 x 6 and also the 2 x 12's - where the 2 x 12's will be sitting on the 6 x 6 posts. I can not find a place to purchase these. Anyone have an idea where I can obtain these. Thanks in advance for your help.
I'd check Simpson and USP's product lines. I can't think of anything that they make that encapsulates the post, but they have some H-brackets that work pretty well.
I know that USP will custom make any hanger or bracket you need, albeit expensive. Your best bet, assuming you can't find something that they make that will work, is to have a local welder/fabricator make something for you.
If the work is being inspected, you'd obviously need the engineer's blessing on whatever you use.
