The Floor Has Beam

When using a steel floor beam some builders apply a bead of epoxy or strong glue under the floor joists to prevent them.

The floor has beam. 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. 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.

What if we needed to span more than that. Our floor joist beam can span a maximum of 13. Let s say our house is 24 x. 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.

It also has a tear resistant covering that makes it a great choice for outdoor workouts or physical therapy sessions.

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.

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.
