Floor Beams And Joists

Floor joists rest directly on beams.

Floor beams and joists.

Common sense tells you that large floor joists can carry more load and spacing joists closer together also increases the load bearing capacity of a floor. Like other framing components beam and joist floor frames are often pre constructed transported to the site and attached to stumps or. Though joists may be any size that you desire using typical floor joist and beam specifications ensures that you can find hardware to fit the joists and that the floor provides adequate support for furniture and other items in a room. The extra two inches of vertical distance when a floor is framed with 2 x 10 joists rather than 2 x 12s can be quite important for example.

Both stretch across long spans. Beam and joist arrangements can form a supporting frame for a floor. Joists also may get support from beams located at or near the middle of the joist span. The most common example can be seen in a basement or crawlspace where a large main beam runs down the center of the space and is supported every 8 feet or so with a column or concrete pier.

That is beams and joists are building parts that lay flat rather than stand up. Walls and columns often sit on floors so they may rest indirectly on beams. Floor joists or beams provide the below surface support for the wood subfloor of a room. Joists are typically shorter and lay across the beams to give them horizontal support.

Beams are thicker and longer and are laid vertically. This beam supports the floor joists of the house s ground floor. Technically joists are a type of beam. But larger is not always better when builders are constructing a home or adding a room addition.
