The use of long span beams results in a range of benefits including flexible column free internal spaces reduced foundation costs and reduced steel erection times.
Beam runs from slab to attic.
Inside pipes can be run vertically to accommodate new plumbing.
If you have an attic over your garage these joists also bear the load of your attic flooring and any materials you store in the attic.
When running pipes from a slab to an attic use an inside wall.
I recently repaired a pipe at the back wall of my home where as l had to dig under the slab and it was reachable.
In a house that has an unfinished basement or easily accessible wall finding the beams typically a metal i beam or a multi board wood beam is a good indication of where the weight of the.
The chase is most commonly used for running new vent stacks.
All lines are coming from under the slab in each part of the home where water is needed.
The wooden joists or beams over your garage help hold your roof in place.
With newer foundation systems involving embedded rebar or tension cables making in slab hvac ductwork nearly impossible there s little other option but to move it to the attic.
A triple 2 x 12 beam should have at least 3 solid 2 x 4 s underneath it not just below the double top plate but also above it if the beam is not resting on the top plates.
Similar to the chase is the soffit.
I now have a water leak that could be further under the slab and not reachable.
If an internal wall has a large boxy section or an enlarged column at its end this may be concealing a main structural support beam a sign that the wall is load bearing.
When ever beams are added and are bearing on a wall solid 2 x 4 s should be filled in under the beam in the wall frame to match the width of that beam.
In the 70 s and 80 s in slab hvac ductwork was commonplace and took advantage of the relatively stable temperature of the slab at or near the ground.
Instead of running from floor to ceiling a soffit runs across the top of a wall.
Many long span solutions are also well adapted to facilitate the integration of services without increasing the overall floor depth.
This allows plumbing to run from the basement to the attic.
If you need a storage area above your garage strong ceiling joists are necessary to support the added weight.
However because these support beams are relatively large compared to non load bearing studs often the wall itself will be designed to accommodate the extra size of the beam.
