Hi everyone! I've finished several support walls in part of my basement, the ones under the kitchen/pantry part of a hallway. I've also finsihed sistering about 80% of the floor joists that I need to. I am now to an area in the basement where the two previous solutions I've used will either severly intrude on the dynamics of the basement (another wall) or be near impossible to install (sistering joists.) So I need to build a beam.
The beam shall be 10' in length, Height and width will be whatever they need to be. It will be supported with two posts (material yet to be determined) at the 1' and 9' marks more or less.
The purpose of the beam is to reduce the span of the joists from 12' to 9'.
Current joists system is 2x10's 12' long 16 O.C. It's also a bathroom floor....the area i want to help support.
So would something like 3 2x12's with 2 pieces of plywood, glued an nailed sufice?
Once in place, I'll probably jack the sucker up a tad to slide my posts in place.
see diagram.... when I've built the couple of supporting walls, the wall header was able to go up or down slightly to make up for the differences, plus I cut each wall stud to fit exactly so no gaps like will occur with beam....
