Connector, method for connecting structural members with connector and connection structure between structural members

A connection assembly for assembling structural members comprising a tubular member having circumferential sidewalls, a first end and a second end, and a removable hollow branch pipe, said circumferential sidewalls being solid and without perforations, said branch pipe engaging said tubular member at said first end and said second end having an adhesive guiding groove formed in a concave shape at the surface of said second end, said second end formed in a domed shape so that liquid adhesive poured into said tubular member from said branch pipe flows-out to said adhesive guiding groove through said second end of said tubular member.

An assembly comprising a first structural member having a first face, a second structural member having a second face abutting said first face, a first borehole extending into said first structural member from said first face, a second borehole extending into said second structural member from said second face, said first and said second boreholes having aligned openings at said first and said second faces, a connector comprising a tubular member, said tubular member being positioned in said boreholes bridging between said structural members and being smaller in cross section than said boreholes to leave clearance between said boreholes and said tubular member, said tubular member further comprising a first end having means to allow for the flow of adhesive out of said first end in a direction transverse to an axis defined by said tubular member, said tubular member further comprising a side wall having a length wherein the majority of said length is solid and without perforations, so that all of a liquid adhesive introduced to said tubular member at an inlet end will flow to said first end, out said means to allow for the flow of adhesive out of said first end, and then flow in a reverse direction to cause said clearance to fill.

A connecting method for connecting two solid structural members comprising a first step of boring a connecting hole portion communicated from one structural member to the other structural member in a connecting portion between structural members, a second step of inserting a connector comprised of a tubular member at which end is engaged a branch pipe into said connecting hole bored by said first step, wherein an annular cavity remains between circumferential sidewalls of said tubular member and said connecting hole, a third step of pouring an adhesive into said branch pipe of said connector inserted by said second step whereby said adhesive flows through said branch pipe, then into said tubular member and then out a distal end of said tubular member and then in a reverse direction into said annular cavity and toward an opening of said connecting hole, and a fourth step of releasing the engagement between said branch pipe and said tubular member to remove said branch pipe.
