A splice joint is a method of joining two members end to end. The splice joint is most often used when structural frames are required in longer lengths than available. It is an alternative to other joints such as the butt joint and the scarf joint. Splice joints are stronger than unenforced butt joints.
Potential for bolt shear in load bearing applications.
Space bolts as widely apart as possible for strongest joint. Add additional bolts for an even more secure joint.
Frames may be spliced together more than 2 wide in an alternating diamond pattern to form something akin to plates.
