The end supports are the bearing walls
that carry the vertical load of the roof to the foundation.
or more, build one support wall, making it close enough to the bearing wall
to support the joist ends.
To appease the plumbing gods, the codes have made at least one notable exception: In bearing walls
you can bore 60 percent size holes--as long as you double up the studs and don't drill through more than two successive pairs of these doubled-up studs (Fig.
Trimmers support headers in bearing walls
. But just like headers, they're found in non-bearing walls too, because they make nailing on trim easier.
NOTE: We're using "bearing wall
" here to describe interior walls.
The McKays could have replaced the bearing wall
with a wide archway supported by a beefy header, and perhaps, flanked by "wing walls" (see Photo 1).
However, there are a few exceptions to these guidelines in locating bearing walls
. Sometimes a joist pattern changes direction at a wall, or unusual ceiling angles dictate a more complex design.
We're going to show you the key steps for the more challenging project, removing a bearing wall
and replacing it with a beam.
If you answered yes to Questions 1 and 2, you have a bearing wall
. When you tear it out, be prepared to substitute in its place a heavy beam supported by wood studs on both ends to support the floors or roof above.
The rim joist is the solid blocking around the outside of the building, but you also need blocking under interior bearing walls
A determination has to be made whether the combination will have an impact on load bearing walls
, relocation of risers and vents as well as, plumbing, heating and electrical lines.
The presence of a courtyard together with thick cement-brick bearing walls
ensures an internal comfortable environment especially in summer.
