Abstract
An adhesively joined laminated structure comprising layers of flat elongated members, at least a first member of which comprises wood and at least a first surface of the first member being treated with a preservative chemical. A recess may be provided in the first surface of the first member to improve preservative chemical absorption.
Claims20
A laminated assembly comprising:
- adhesively-joined layers of flat elongated members, at least a first member of which comprises wood and is arranged in the laminated assembly such that a first surface of the first member abuts a first surface of a second member of the laminated assembly;
- a longitudinal channel defined within the assembly by a longitudinal recess formed into and along the first surface of the first member and by a portion of the second member facing the recess;
- and
- a preservative chemical absorbed into the recess and into at least the portion of the second member facing the recess.

A laminated assembly comprising:
- adhesively-joined layers of flat elongated members, at least a first member of which comprises wood;
- at least a first surface of the first member being treated with a preservative chemical;
- a recess provided in the first surface of the first member;
- a first groove formed longitudinally into and along an entire length of the first surface of the first member;
- a second groove formed longitudinally into and along an entire length of a facing surface of the second member;
- and
- the first and second members being disposed such that the facing surface of the second member abuts the first surface of the first member and the second groove cooperates with the first groove to form a single channel.
4 more elements
A method for making a laminated assembly, the method including the steps of:
- providing a plurality of elongated members, at least a first member of which comprises wood;
- forming a longitudinal recess into and along at least a first surface of the first member;
- treating at least the first surface of the first member with a preservative chemical after performing the forming step;
- incorporating the first member into a laminated structure by arranging the first member in the laminated assembly such that the first surface of the first member abuts a first surface of a second member of the laminated assembly and such that the longitudinal recess cooperates with a portion of the second member to form a longitudinal channel within the assembly;
- and
- adhesively joining at least a second surface of the first member to a surface of at least a third member to be incorporated into the laminated assembly.
