Panels Connect with Internal Spline

Adjacent floor panels with compatible routed channels are butted together. A wood spline is placed in the channel across the joint and fastened with partially-threaded screws or nails.

Purpose: Transfer of in-plane shear along the panel-to-panel joint.

Design Notes

  • Capacity of connection is controlled by shear capacity of dowel-type fasteners.
  • Preferable for conditions that require a hidden connection or where one side of the panel is inaccessible during construction.
  • Requires extra care during installation as spline is susceptible to damage while placing panels.
  • Where using nails, consider specifying nail gun nails instead of common wire nails for constructability, or collated screws instead of individual screws.
  • Increased cost compared to surface splines due to increased construction time.
  • Typical minimum plywood thickness is ½” nominal.
