Thinking this is really strong.

Wish I knew how to read those structual tables on lumber. Butt the end of a 12-foot board against the end of the 4-foot board. Through-bolts would be much stronger than screws.

Based in Nashville, Shellie Braeuner has been writing articles since 1986 on topics including child rearing, entertainment, politics and home improvement. Get 2) 1-3/4" X 11-7/8" lvls. What I have done is kept the 2 2 X 4 top plates, put in 2 2 X 10 with 1/2 inch plywood in the middle under the two toe plates, making the beam about 12 1/2 inches deep.

In the end he has the final say. I volunteer my help and opinions, but you are responsible for what. Besides, screws are not allowed for in structural applications unless they are specified by and Engineer and are of the right type. Additionally, bolting boards together allows the builder to make a beam longer than the standard 12-foot length of the lumber. Some long wood beams are actually made of engineered wood, which is mix of materials that includes wood. You also have to look at whether any roof loading is carried down to the beam. Drill two holes through the end of both boards. I built my open house with openings large then this by using 2 X 10 's and lots of 3/4 inch plywood.

My building inspector would never specify a beam, that would suggest he was accepting responsibility for the design, which he would not do.

If you're supposed to use a 4x6 timber, you might not be able to substitute a built-up beam made from two 2x6's. I am building a small storage loft (about 10'x10') in my shop and want to build a beam to span 9'6", made from 2 - 10' long 2x8's with 1/2" OSB sandwiched between and fastened together with Liquid Nails and 16d nails every 8" or so. Lay a 4-foot piece on top of the 12-foot board and line up the ends. Thicker beams can give the added support. Always use care when cutting or shaping wood with power tools. HELP IS NEEDED. Consider the amount of labor to construct your own beam, versus picking one up at the yard. The further away from the two side supports the joint is (so the more in the middle the joint is), the more stress there will be on the joint. Some of the inspectors can be real bears. What else can I do to make my beam equal to a LVL he wanted? © Copyright 2020 Hearst Communications, Inc. Beams support roof or floor structures. Huge difference between made up LVL beams and dimensional beams. JavaScript is disabled. When building a hundred years ago people had openings 13 feet or more and they put in beams. The beams are usually 8 inches wide so that holes for plumbing and electrical lines can be cut or drilled through the beams without destroying the structural integrity of the beam.
