The Floor Has Beam

Floor joists or beams provide the below surface support for the wood subfloor of a room.

The floor has beam.

The floor beam itself is commonly hidden by the ceiling tiles of a finished basement while the jacks are usually boxed in and blended into the surrounding area by use of paint paneling or wallpaper. Look for a floor balance beam that is multipurpose if you want it to do much more than just assist in gymnastics training. In the table above the widest floor beam span for 12 of supported floor joists is 14 7 if using a 5 ply 2 x 12. The widths of the supporting beams are provided.

What if we needed to span more than that. For a main supporting center beam in a 24 36 foot deep house depth being the smaller dimension presumably the beam is running down the length of the house so supporting floor joists which run across the depth direction of the house so say 12 18 long floor joists on each side of it the beam would normally span up to about 14 28 feet. It also has a tear resistant covering that makes it a great choice for outdoor workouts or physical therapy sessions. All dimensions are to centers of beams.

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. Given the floor plan on the attached page determine the effective widths of the flanges of beams b1 b2 b3 b4 b5 b6 and b7. Our floor joist beam can span a maximum of 13. So we now have adequately sized floor joists and an adequately sized floor joist beam for our 24 x 13 house.

In an unfinished basement the beam and jacks are typically left exposed. Let s say our house is 24 x.
