Wood Beam Bolt Pattern

The shear capacity indicated in table 1 is the shear strength of the wood alone since the full beam reaction must be transferred through the wood side pieces at end bearing supports.

Wood beam bolt pattern.

Single sided installation flatlok is approved for single sided installation making the job easier to complete both at ground level or for elevated applications. This is a table for single shear bolt capacities. Starting about 2 inches from the edges of the beam counterbore two holes on the inside or the least visible side of the beam for carriage bolt nuts. It should be noted that the equations presented in this section for calculating pattern properties do not require the bolts in the pattern to be the same size.

Use 2 pieces 1 4 1 2 ply for symmetry. The revolutionary top cover plate interlocks with the ledge and adjusts to the thickness of the beam and can be used on smooth or rough cut wood. The same properties that are required when analyzing a beam or a shaft are also required when distributing forces over a bolt pattern. This is a reasonable.

The values in table 1 are based on the steel plate being a36 steel. If last bolt in top and bottom rows are more than 8 from end add bolt 1 1 2 from end. Flatlok is a multi purpose structural wood screw for fastening multi ply lvl girder trusses and multi ply lumber beams. Veneers arranged in a specific pattern to maximize the strength and sti ness of the veneers and to disperse the naturally occurring characteristics of wood such as knots that can weaken a sawn lumber beam.

For beams where the load comes down evenly on top of the beam such as drop beams or beams directly under bearing walls the nailing pattern is not all that critical. The bolt inline kit is ideal for roofs larger pergolas and higher rafting. The owt bolt inline kit is designed for use with 6 or larger posts. Disassemble and apply glue in a triangle inside every and formed by bolt holes and along each edge.

Drill through the beam with a long bit the same diameter as the bolts. Repeat this process at 16 inch intervals across the length of the beam. This is conservative since the flitch beam being sized actually has bolts in double shear. Beams since these members contain three wood pieces.

Gives a w pattern. Lp solidstart lvl beams are exceptionally strong. The veneers are then bonded with waterproof adhesives under pressure and heat. For simplicity use table 11b of the national design specification.
