A reader's General Construction question: Timber steel connection?
Adrian D. from Bundaberg Australia had this Timber steel connection question.Hi Bill i have just bought a 2 story queenslander and the house has H or I beams holding it up and also has the same beams as Bearers for a deck and I was wondering how do you attach timber joists to the steel beams?
Adrian, You have caught me on holiday at present in Vietnam, working on a clunky computer, so this will be brief.
Two ways, before cyclone coding where we are we either bolted or ramset gun fixed a 100 x 50 timber to the top of the steel beam, and then nailed or triple gripped the joist to that.
Best way is to weld on cleats. Typically with 150 x 50 joists they would be say 50 x 140 x 5 or 6mm thick flat with 14mm holes for two 12mm bolts. Cleat 6mm complete fillet weld (6cfw) to beams.Cheers from Hoi An
