Panels Connect with Single Surface Spline
Adjacent floor panels with routed surfaces are butted together. A plywood spline is fastened to both panels using partially-threaded screws or nails.
Purpose: Transfer of in-plane shear along the panel-to-panel joint.
Capacity of connection is controlled by shear capacity of dowel-type fasteners.
- Double surface spline or steel surface spline can be used for increased capacity.
- Spline may be fully above panels without routed surface where floor or roof coverings allow.
- Where using nails, consider specifying nail gun nails instead of common wire nails for constructibility, or collated screws instead of individual screws.
- Where screws are used instead of nails, cost increases and constructibility is moderate.
- Typical minimum plywood thickness is ½” nominal.
- Coordinate spline and rout width and thickness with panel supplier.
- In diaphragm design, consider that, for extreme in-plane bending, bearing in the connection will occur. It is preferable for the panels to bear on one another before bearing on the spline, which is achieved by specifying a larger gap between the spline and panel than between the two panels.
