Panels Connect with Half-Lap Joint – Perpendicular Intersection
Intersecting panels with compatible notches are lapped and connected using partially-threaded screws or nails.
Purpose: Transfer of in-plane and out-of-plane loads between panels. Often used as an erection aid only where connection is not otherwise structurally required.
- Capacity of connection is controlled by shear capacity of dowel-type fasteners.
- Orientation of the notches will determine the construction sequence.
- Screws are more common than nails, in particular as panel thickness increases.
- Notch width is generally controlled by screw edge distance requirements, which vary by manufacturer.
- May be designed to carry lateral loads across joint. Reinforcing screws may be required for this application.
- Inconsistencies in notch depth can cause surface variations in adjacent panels.
