Abstract
A log construction has a pair of logs, each having an end region with a surface portion thereon, wherein the surface portions are arranged to engage one another at a boundary therebetween, the boundary having a length. At least one barrier extends across the boundary and along the length thereof to couple the end regions together, the barrier having a pair of projections. Each of the logs has a passage open to and adjacent the boundary for receiving a corresponding one of the projections. Each projection has a pair of outer surfaces and the passage having a pair of inner surfaces, the outer and inner surfaces being further arranged to generate residual compressive forces toward the boundary as a result of shrinkage between the barrier and the end regions.

A log construction comprising:
- a pair of logs, each having an end region with a surface portion thereon, wherein the surface portions are arranged to engage one another at a boundary therebetween, said boundary having a length,
- at least one barrier extending across said boundary and along the length thereof to couple said end regions together, said barrier having a pair of projections,
- each of said logs further comprising a passage open to and adjacent said boundary for receiving a corresponding one of said projections,
- each of said projections having a pair of outer surfaces and said passage having a pair of inner surfaces, said outer and inner surfaces being further arranged to generate residual compressive forces toward said boundary as a result of shrinkage between said barrier and said end regions.
A method of forming a log construction comprising the steps of:
- providing a pair of logs, each with an end region having a surface portion thereon,
- arranging the surface portions are arranged to engage one another at a boundary therebetween, said boundary having a length,
- providing at least one barrier to extending across said boundary and along the length thereof to couple said end regions together, said barrier having a pair of projections,
- forming in each of said logs a passage open to and adjacent said boundary for receiving a corresponding one of said projections,
- forming on each of said projections a pair of outer surfaces and in said passage a pair of inner surfaces,
- arranging said outer and inner surfaces to generate residual compressive forces toward said boundary as a result of shrinkage between said barrier and said end regions.
