The king post truss is one of the most common truss forms used in timber framing. Some, but not all king post trusses utilize struts (diagonal beams coming from the bottom chord).
Timber Frame Construction Details
When you have two beams connecting into one post at the same height, you need to get creative in cutting the joints. The goal here is to make a secure connection without taking too much meat and strength out of the post. In this detail we show you how to accomplish that with an Offset Mortise and Tenon.
Cross lap joints are a great solution when you want to create clean, continuous lines in a timber frame. The edges of the joint are completely flush, making it almost appear that the timbers are magically connected. To create a cross lap joint, you cut halfway through the width of both timbers that you are connecting , and they slide together into an extremely solid joint.
