LVLs: A Strong Backbone for Floor Framing - Fine Homebuilding
Carrying beams can be dropped beams (installed under floor joists) or flush beams (installed in plane with floor joists). Dropped beams make floor framing faster because the joists run over the beam in continuous lengths. Rather than sitting on the mudsills, a dropped beam typically requires a pocket in the foundation wall to support each beam end.
Installing Support Beams - Fine Homebuilding
The mudsills support the ends of the floor framing, but most houses require support for the middle of the floor framing as well. Support beams or girders provide that support. A support beam can be made of various materials, including steel, LVL, and glue-laminated 2× stock. Most often, though, it is made from built-up layers of dimensional ...
Installing Floor Joists - Fine Homebuilding
The joists overlap at the support beam, so instead of marking an X on the side where the joist sits, mark an F (front joist) on one side of the line and a B (back joist) on the other side. Once the joist layout is marked on the mudsills, go back and lay out …

Support beam. Also called a center beam, the support beam bears the first-floor joists if they are not long enough to span the entire distance between foundation walls. The ends of the support beam bear on the foundation walls; intermediate support below the beam is usually provided by Lally columns (hollow-metal columns filled with concrete).
Splicing Deck Joists Over a Beam - Fine Homebuilding
2022年8月23日 · The joists must be fastened to the beam—Table R602.3(1) calls for a minimum of three 8d common or 10d box toenails from the joist into the beam. With only a 1-1⁄2-in. bearing for in-line joists, it will be hard to drive the nails without splitting the joists, so metal connectors like the Simpson Strong-Tie H2.5AZ may be a safer alternative.
Joist hangers vs joists resting on beam? - Fine Homebuilding
2005年6月23日 · Clearly, resting on the beam is stronger, so long as the joist can't twist sideways. But there's no real advantage in being able to take, say, a ten thousand pound load when one thousand is the most you actually need. Given that, the main advantage of resting on the beam is that there are fewer ways to screw it up.
Anchoring Wood to a Steel I-Beam - Fine Homebuilding
Modern floor plans are trending toward wide open spaces. Despite advances in engineered-wood beams, there are times when something stronger is needed. Many carpenters shy away from steel because fastening lumber to steel can be tricky. Cutting a steel beam on site is even trickier. Sometimes, though, a steel I-beam is the best choice.
Clever Fix for a Sagging Floor - Fine Homebuilding
Provide support. Temporary walls support the floor on both sides of the beam until the joist hangers are attached and the beam’s ends are supported with posts. The studs are scribed and cut individually to ensure a tight fit. Leaving off the top plate provides an additional 11⁄2 in. so the studs can be used for partitions later.
Using steel to strengthing joists. - Fine Homebuilding
2006年1月21日 · The wood only providing support to prevent lateral deflection. A role which in many situation is largely redundant seeing as that, especially in the case of a floor joist, the floor above and ceiling below prevent lateral deflection and buckling. Some structural engineers loosely characterize flitch plates as 'A waste of both wood and steel'.
Floor-Framing Design - Fine Homebuilding
It simplifies construction when you can clear-span the floor joists, but while TJIs are available up to 24 ft. long (or longer, by special order), our roof framing system required support near the center of the house, so we used a typical center beam in the basement and a bearing wall on the first floor. We up-sized the center beam at the ...
