I adapted a 'cherry-picker.' I'll post that up in a new thread. I even went as-far as-to buy a short-web I-beam with the idea to bolt it to the underside of the box beam at the ridge, but I discovered that between the I-beam girder, the trolley, and the rigging, I would lose precious headroom, and be unable to lift much over 3' in height onto the loft deck. If it was an I-beam girder I could use an overhead trolley on the lower surface flange of the beam, but due to the box construction, that was out. One concession I made to getting heavy things up & down to/from the loft, I thought about what would make an easy load-lifter? The roof ridge beam is also a 1/2" wall thickness box beam with plates welded to it for the ceiling joists. For access, I use an A-frame ladder, but since it's used for storage, it's not an everyday trip I make. The structure has no stairs to access the loft, not-even an attic 'pull-down' stairs. The beam is sandwiched on both sides by a 2" x10" (ripped to 8" to match the box beam dimension) wood beam to allow easier attachment of the loft floor joists, which are 2" x 8" & 18" o.c. The engineer did the calcs and gave us a front-of-the loft steel box beam, 1/2" wall thickness, 4" x 8" welded into steel flitch plates cast into the masonry side walls. We used a structural engineer, and I asked for a capacity capable of supporting the weight of multiple motorcycles. The garage is a nominal 20' x 22' & the loft is a nominal 13' x 22'. That's all we could afford to do, we kept the same roof instead of bumping it higher. When the material arrives on the jobsite, there is minimal cutting, and carpenters know exactly where every joist goes.I had built a loft which isn't full height above my two-car garage. This software creates a layout and specifies where every single framing member goes. Joists can also be spaced wider than traditional solid sawn joists which allows for quicker and easier installationĪll TJI Joists are designed using patented software that designs a floor taylor-made for every home. Large holes can be cut in the webbing of TJI Joists, allowing for mechanicals to be easily run and installed. Allow for spacing for HVAC, Electrical, and Plumbing 1) the LVL flange holds fasteners better, preventing loose nails that cause squeaks, and 2) it will not shrink over time with the moisture change which is another common cause of squeaksĪll TJI Joists will be perfectly straight and will not twist, warp, or cup I-Joists can span up to a whopping 32' without support, giving custom home builders the ability to create open floor plans that customers demandĪn LVL flange is critical for a high performing floor because it prevents squeaky floors in two ways. Multiple depths and series for any application LVL Flange for superior strength and a squeak-free floor L/480 is the design criteria we recommend for the best performing floor To Submit Blueprints for Takeoff's - Click Here And is one of the most trusted brands in the building community today. Has been the #1 used I-Joist for the past 14 years Pushed the limits of span charts to make the open floor concepts of today a reality Lead innovation and design to create a suite of Engineered Wood Products, including I-Joist, LVL Microllam, LSL Timberstrand, and PSL Parallam Invented the very first I-Joist over 50 years ago When you choose Trus Joist, you're choosing the brand that:
