Joists and Purlins for Timber Frame Buildings
Timber purlins and joists form the roof and floor framing in timber framed buildings. The old school way to do the joinery is to dovetail them in. Unfortunately, the beautiful dovetail is hidden in the finished building, but its strength and integrity is not. It is a strong joint that lasts over time.
When very heavy loads are involved in a floor or roof system, we use shouldered lap joints. The lap joint allows us to maintain cross sectional area in the girts (main carrying beams).
