Abstract
A connector and method for joining one end of a first wood member such as a wood log or beam to a side of a second wood member involving metal sleeves secured in aligned holes in a respective member with a protruding one of the sleeve slidable into the other sleeve. A bolt is threaded into an internally threaded element on the inner end of the sleeve in the first member and advanced to pull the members together. The sleeves are secured in the holes with spike features driven out into the surrounding wood. Alternatively, a tee connector has a plate portion fitting into a slot extending through aligned holes in the plate and one end of the first member. A cross plate is held against the one side of the other member with thread fasteners.
Claims8
A joint between two penetrable members in a position with
- a surface of a first member abutting against a surface of a second member, comprising
- a first sleeve secured within a first hole extending in from said first member surface by engagement with surrounding portions of said first member defining said first hole;
- a second sleeve separate from said first sleeve fixedly secured in a second hole extending through said second member by engagement with surrounding portions of said second member defining said second hole, said sleeves overlapping with said first sleeve having an end portion protruding from said first member and slidably received within an inside diameter of said second sleeve with said surfaces of said members in said abutting position against each other;
- an internally threaded element secured adjacent to an inmost end of said first sleeve in said first hole;
- a threaded locking bolt extending through both of said sleeves and threaded into said internally threaded element fixed to said first sleeve, said bolt having a head engaging a surface fixed relative said second member to enable said first and second sleeves to be drawn together by threaded advancement of said bolt in said element each of said sleeves are secured in their respective associated holes by penetrating spike features on said sleeves penetrating radially into portions of said penetrable members surrounding said holes, and a third sleeve extends into the inside of the first sleeve to force said spike features thereon radially outwardly into said portions of said first member defining said first hole and driving a cylindrical tool into said second sleeve to drive said spikes radially out into said second member;
- and;
- an end piece having a sleeve portion fit into said hole in said second member and against an end of said second sleeve remote from said first member and also having an end wall comprising said surface fixed relative said second member abutted by said head on said bolt with an opening therein allowing a body portion of said bolt to pass through said end wall.
A method of joining a first penetrable member to a second penetrable member with respective surfaces thereof in abutment, including forming a first hole extending into a surface of said first penetrable member;
- inserting a first sleeve into said first hole and securing the same therein by attachment to surrounding portions of said first member defining said first hole;
- forming a second hole extending through said second member and said surface of said first member;
- separately inserting a second sleeve separate from said first sleeve into said hole in said second member;
- securing said first and second sleeves to said first and second members respectively by forcing spike features formed inside each of said sleeves out into said surrounding portions of said respective members defining said first and second holes by forcing a third sleeve into the inside of said first sleeve to force said spike features thereon radially outwardly into said portions of said first member defining said first hole and driving a cylindrical tool into said second sleeve to drive said spikes radially out into said second member;
- configuring said first sleeve to protrude out of said first hole and slidably fit in an inside diameter of said second sleeve when said respective surfaces of said members are positioned against each other;
- inserting a threaded bolt through said sleeves from an opposite side of said second member and threading the same into an internally threaded element fixed at the inside end of said first sleeve, with a head on said bolt engaging a surface fixed relative said second member so that said first and second members are drawn together by advancement of said threaded bolt in said internally threaded element.
