Beam Assembly

The redrilled flitch beam steel plates were painted in red, yellow and orange, which are the New School colors and the color of sunset.

Instead of measuring, bolt holes on the flitchbeam lumber pieces were located with the steel plate placed on top. 

Joists were made of two pieces of 2x12 and relatively easy to assemble.

Grasshopper helped us to move those heavy joists from the shop to the site.

Girders waiting to be lifted.

Every flitch beam was made of four pieces of 2x12 and one 1/2” thick steel plate. All pieces were sandwiched together to make the flitchbeam. These were the girders.

These small triangular components were cut with track saws and special jigs.

The triangular pieces sat in the notches on the flitch beams (girders). 

Steel T brackets, installed and leveled. These are the connectors between girders and joists.


Installation

The folklifter lifted the girder into place. A four person team guided the girder into column caps and aligned the holes on the column caps and the girder.

Joists were slid onto T brackets on the girders.

The notches on corner girders were adjusted.

Two primary beams intersected on the corner. The girder was notched into the joists inside of the column cap. Both primary beams continued to cantilever.

45° bracings were installed to increase the stability of the roof system.

Wood beams warped after rain. Cargo straps were used to adjust the spacing between joists.
