This mortise and tenon joint uses a wedge in conjunction with a tapered tenon and mortise to hold itself together giving you a clean looking connection. The key in this joints strength is to have all the bearing surfaces between the post, wedge and tenon fit perfectly. The wedge’s large face faces outwards towards the housing […]
Timber Frame Construction Details
There are several methods for securing a timber post to a solid poured concrete pier, slab or foundation. In this example a flat piece of plate steel with rebar fingers is embedded in to the concrete. Then the elevated post base is attached to the timber post through a knife plate which is held together […]
Often we find ourselves with a large amount of tension in some connections involving the roof loads and it is necessary to add some steel instead of relying on wooden pegs to do the job. This is not just a new age practice but one that has been around for a long time. An easy […]
There are a few ways to join two rafters together at the peak, one way that we have illustrated before is the tongue and fork connection. In this detail a simple mortise and tenon is used to simplify the process of cutting the joint. Please note that the tenon and mortise are notched back from […]
It is often the case when you have two or more plates or beams coming together into a post to use a spline in place of a tenon. The thought process being is if you put a tenon on the end of the beams you risk taking out too much “meat” out of the post […]
As its name implies this tying joint, joins together 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.
This strong and simple to cut joint joins a rafter to a tie beam in a wide variety of truss combinations. The notch is what creates the strength in this connection. It uses the roof pitch on the inside edge and a 45 degree angle on the outside of the notch.
A scarf joint is used to create longer timbers for use in plates, beams, rafters and posts when you cannot find a long enough timber to span the distance you require. The stop splayed scarf that is displayed here is extremely common and can be fastened together with pegs, all-thread with nuts and washers or […]
In a hexagonal timber frame where the plates around the perimeter join the with principal rafter is a bit tricky from a engineering stand point. This is just one solution and in this case a steel post was used instead of a timber post. After the last detail I thought a follow up to the […]
While just housings and rafters to cut this detail would certainly challenge any timber framer. The central post is typically called a boss pin and it is used when you have several hips and valley coming together at the some spot. This details comes from a hexagon frame and has the lower struts diving into […]
