Micro lock mortise riveted joint frame two ply solid wood hybrid engineered flooring

摘要

Disclosed is a new type of two-ply solid hybrid wood flooring system that utilizes an improved, more dimensional and stable solid wood backing layer or foundation with continuous solid structural edge beams made out of many small pieces of finger jointed solid wood strips and bonded together in such a way which eliminates waste of raw material, uses less adhesive and yields the maximum structural stability. The present invention combines the dimensional stability characteristics of a traditional perpendicular-grain engineered flooring product with the benefit of the thickness of the traditional solid wood flooring.

主权项

1. A two ply solid hardwood flooring system consisting of:
a top wear layer; a layer of wood foundation having:
two continuous structural edge beams; andbacking strips of equal widths and thicknesses running in directions perpendicular to the top wear layer and the structural edge beams and jointed to the structural edge beams by a joint;a first interstitial area configured to at least partially fasten said layer of wood foundation and the top wear layer together, the first interstitial area defined by a generally nonhomogeneous layer, the first interstitial area further configured to create friction and coupling surfaces between said layer of wood foundation and the top wear layer; and;a second interstitial area located at said joint configured to at least partially fasten the edge beams and backing strips together, the second interstitial area defined by a generally nonhomogeneous layer, the second interstitial area further configured to create friction and coupling surfaces between the structural edge beams and the backing strips; and;at least one preformatted adhesive strip disposed to position within the first and second interstitial areas, and formatted to said joint, the at least one preformatted adhesive strip configured to help adhere the layer of wood foundation to the top wear layer and the structural edge beams to the backing strips, whereby the at least one preformatted adhesive strip is a separate component from the first and second interstitial areas.
