I have a steel I-beam my in basement and permanent lally columns that are cemented into the basement floor. What is the proper method of attaching the lally colums to the steel I-beam? If it were a wooden center beam, I could nail or bolt through the lally tabs into the beam. Is there a similar approach for steel? Thanks, Larry
In residential constructions you'll often, surprisingly, find the two unattached. They're basically weighted from the top down, with the weight above them holding the lally and I-beam into place. However, the proper approach is, yes, bolting. Insert the bolt through a plate on the top column and through the I-beam.
