Abstract
A joint and method for connecting elongated members end to end in which outer sleeves are anchored in blind holes extending in from each end face and a threaded rod is advanced into threaded nut receptacles affixed to the inside end of each sleeve to draw the end faces into abutment.
Claims11
A joint between two penetrable elongated members in a position with an end surface of a first member abutting against an end surface of a second member comprising:
- a first sleeve anchored within a first blind hole extending in from said first member end 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 blind hole extending in from said second member end surface by engagement with surrounding portions of said second member defining said second hole, said sleeves overlapping with one sleeve having an end portion protruding from an associated member and slidably received within an inside diameter of the other sleeve with said surfaces of said members in said abutting position against each other;
- an internally threaded receptacle secured adjacent to an inmost end of each of said first and second sleeves;
- and
- a threaded rod extending through both of said sleeves and having opposite ends threaded into a respective one of said internally threaded receptacle fixed to an inner end of said first and second sleeves respectively.
The joint according to claim 3 further including inner sleeves each slidably fit within an inside diameter of a respective one of said first and second outer sleeves to force out said spike features to penetrate into surrounding portions of said first and second members respectively.
A method of joining one end of a first elongated penetrable member to an end of a second elongated penetrable member with respective end surfaces thereof in abutment, including forming a blind hole extending into an end 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 blind hole extending into an end surface of said second member;
- inserting a second sleeve separate from said first sleeve into said blind hole in said second member and securing the same therein by attachment to surrounding portions of said second member defining said second blind hole;
- inserting opposite respective ends of a threaded rod through a respective one of said sleeves and threading the same into a respective internally threaded element fixed at the inside end of each of said sleeves so that said first and second members are drawn together by advancement of said threaded rod ends in said respective internally threaded elements.
The method according to claim 10 including forcing said spike features out by inserting an inner sleeve into an inside diameter of each of said first and second sleeves respectively to force spike features having portions disposed within each of said first and second sleeves out into said surrounding portions of a respective first and second members defining each of said blind holes.
