When designing a frame it is a general rule to try and not have too many timbers collide at one point. This is not always achievable. In this example we address one of the most common instances, when we need to connect four beams into a post. In both examples, we housed the beams into the […]
This rafter to post with tenon connection is a popular way to join a timber frame rafter to a post and is easy to cut and assemble. The rafter has a tenon which is fully housed by at least an inch into the mortise in the post, and is secured with a couple of 1” pegs. The […]
This detail was created out of a need to join a timber frame corbel, post and plate together in a hexagonal structure that will serve as a gate hut for a local golf club. In this case the corbel is not carrying any gravity loads but lateral loads. I saw an opportunity to make the […]
Often folks want to add a bit of style to their roof line by adding another roof pitch to the equation, called a witches hat roof, it incorporates a witches hat rafter (also called a broke back rafter) to achieve this look. This example uses an LVL spline and some pegs to hold the two rafters together. Then a couple of […]
It is often the case when you have two or more plates or beams coming together into a post to use spline joinery in place of a tenon. The thought process being, if you put a tenon on the end of both beams you risk taking too much “meat” out of the post that you create […]
As its name implies this tie beam to plate tying joint, unites a tie beam, plates, rafter and posts all in a compact structurally sound way. It utilizes a spline to tie the plates together and traditional mortise and tenon joinery to complete the rest of the joinery.
Often a spline is used in a timber frame to reduce the amount of wood that is taken from a post or beam, this particular connection detail has two knee braces flanking the spline.
