The overall moisture content of the veneer is reduced to the desired level in the jet tube drier by blowing hot air over the surface of the veneer sheets, which causes moisture to be peeled off. But getting the right beam size is important. The installation of support beams can get to be a little more comprehensive, so here are some supporting questions about beam length, span support, and more. It commonly requires one or two temporary walls to support the ceiling or floor structure while support posts are placed or king studs installed, and the new beam measured, cut, and lifted into place. There is an incredibly long list of options to consider when specifying sawn and engineered beams or headers. The width can be increased by laminating in multiples of 1 3/4 inches.

The WSDD tables only list values for solid wood beams at deflection limits of L/360. LVL beam width should be 1/4 to 1/3 beam depth. Lvl sizes may vary according to manufacturer but lvl standard thickness of 1 3/4 inches (one ply), 3 1/2 inches (2 ply), 5 1/4 (3 ply) and 7 inches (4ply). The depth of the beam along with its width, combined with common construction variables such as building width, loads, number of stories, joist spacing, etc., determine its span. Continuous Span Beams are beams supported at three or more points along their length. It worked for most of the applications in our case house. Generally speaking, though, using a 3-1/4 x .131 groove shank nail every four feet apart across the laminate is the best bet.

For every inch of depth, you can safely add about 5 feet to the span. Changing member types automatically sets new defaults to the most common deflection limits, member spacing, and loading conditions. The depth of laminated beams ranges from 5-1/2 up to 24, which means 1-3/4 widths can be represented as 26, 28, 210, and 212 and fit in standard construction fasteners.

I'm a DIY nut, and the founder and chief editor here at Weekend Builds. The span is based on a load-bearing capacity of 1,360 pounds per square foot and a deflection limit of L/360. Finally, there are options that can be checked from snowfall, ceilings with limited storage, 2nd-floorceilings, and so much more. Simple clicks on the drop down boxes will allow variable inputs to calculate a span. You merely look for the distance you need to span; match the load per foot of beam to the appropriate Fb(strength) and E(stiffness) values listed; and bang: you have a winner! Common depth of LVL beam are 5 1/2, 7 1/4, 9 1/4, 9 1/2, 11 1/2, 11 7/8, 12, 14 16 & 18 deep.

To determine the depth of the beam you should use; heres a simple thumb rule using span of beam: the depth of the LVL beam should be equal to the span in inches divided by 20. Laminated Veneer Lumber (LVL) is strong, stiff and versatile. That is more than worth the cost. Once the loads acting on structural beams are calculated, the next step is to size and select the appropriate beam. PSL is an assembly of long, thin strands of wood veneer glued together to form continuous lengths of beam. The width can be increased by laminating in multiples of 1-3/4 inches or 40mm.
