Abstract

It is an object of the present invention to provide a connector in which a strong connection can be carried out with a simple working method, a removal of the connector is eliminated, its workability is remarkably improved, a productivity of building structure is improved, an instantaneous breakage caused by earthquake and the like is prevented and a remarkable anti-disaster effect is attained. The connector (1) of the present invention is comprised of the rod-like member (2), one or two arcular convex walls (8) cooperatively connected to one end of the rod-like member (2) in a longitudinal direction, the hollow part (3) formed from one end to the other end of the rod-like member (2), the insertion hole for fixing member (9) formed at the convex walls (8), and a hollow branch pipe (12) fixed to or removably engaged with the opening of the hollow part (3) at the other end of the rod-like member (2).

Claims

1. A connector comprising a rod-like member having a uniform outer radial dimension from a first end of said rod-like member to a second end thereof;

one or two arcuate convex walls cooperatively arranged at said first end of said rod-like member;

a hollow passage formed in said rod-like member extending through said first end and from said first end of said rod-like member to said second end thereof;

an insertion hole for a fixing member formed through said arcuate convex walls; and

a hollow branch pipe removably engaged with an opening of said hollow passage at said second end.

2. The connector according to claim 1 further comprising an exterior surface of said rod-like member which is formed with a plurality of projection parts.

3. The connector as recited in claim 1 wherein said arcuate convex walls further define a slot in the end of said rod-like member, said slot communicating with said hollow passage.

4. The connector according to claim 1 wherein said opening of said hollow passage of said rod-like member at an end part of an engaging part of the branch pipe is provided with a projection formed in parallel direction with a direction which said fixing member is inserted into the insertion hole or a flange part having a recess formed therein in a crossing direction with the direction which said fixing member is inserted into said insertion hole.

5. The connector according to claim 4 further comprising an exterior surface of said rod-like member which is formed with a plurality of projection parts.

6. A connection between a first and second solid structural members wherein a first said member is provided with a through hole and a second said member has a bore hole and said through hole and said bore hole are opposite and axially aligned and further comprising a connector as recited in claim 1 and a liquid adhesive filled within said rod-like member of said connector and a clearance between the exterior surface of said connector and inner walls of said through hole and said bore hole, and said fixing member comprising a locking pin intersecting said rod-like member near said first end.

7. A method of connecting two solid structural members comprising providing a bore hole and a through hole, abutting said bore hole and said through hole so that said holes are in axial alignment, inserting said rod-like member of said connector as described in claim 1 within said bore hole and through said through hole, providing an insertion and fixing hole transversely intersecting with said bore hole, inserting said fixing member comprising a locking pin through said insertion and fixing hole to engage said rod-like member, filling said rod-like member with liquid adhesive wherein said adhesive flows through said hollow passage of said rod-like member to a deep region of said bore hole and then returns toward a non-abutting surface, filling a clearance between the exterior surface of said rod like member and inner walls of said bore hole and said through hole.

8. A connector comprising a rod-like member having a uniform outer radial dimension from a first end of said rod-like member to a second end thereof, a hollow passage formed in said rod-like member extending through said first end and from said first end of said rod-like member to said second end thereof;

an insertion hole formed at said first end of said rod-like member transversely intersecting the axial direction of said rod-like member and, a fixing member having a smaller diameter than the diameter of said insertion hole whereby said insertion hole can receive said fixing member, and a hollow branch pipe removably engaged with an opening of said hollow passage at said second end of said rod-like member.

9. The connector according to claim 8 further comprising an exterior surface of said rod-like member which is formed with a projection part or a concave part.

10. The connector according to claim 8 wherein said opening of said hollow passage of said rod-like member at an end part of an engaging part of said branch pipe is provided with a projection formed in parallel with a direction which said fixing member is inserted into said insertion hole or a flange part having a recess formed therein in a crossing direction with the direction which said fixing member is inserted into said insertion hole.

11. The connector according to claim 10 further comprising an exterior surface of said rod like member which is formed with a plurality of projection parts.

12. A connector assembly for the attachment of solid structural members comprising, a hollow elongate rod-like member having a uniform outer radial dimension from one end of said member to a distal end of said member, said hollow elongate rod-like member defining a hollow passage extending from said one end through said distal end, means to provide for an unimpeded flow of adhesive from said distal end of said hollow elongate rod-like member in a radial direction, an insertion hole transversing said hollow elongate rod-like member at said distal end, an elongate fixing member, said elongate fixing member receivable in said insertion hole, and a hollow branch pipe, said branch pipe communicating with said hollow passage in said hollow elongate rod-like member.

13. A connection between two solid structures comprising connector assembly as recited in claim 12, further comprising an adhesive, said adhesive filled within said hollow passage provided through said rod-like member and in a space defined by the exterior surface of said rod-like member and the inner walls of connection holes formed within said solid structural members.

14. A method for connecting a building structure comprising the steps of inserting a rod-like member of a connector between two or more structural members provided with connection holes for inserting and fixing said connector;

inserting a fixing member into an insertion and fixing hole formed through an extremity end of one of said connection holes from an outer wall part of the structural member and into an insertion hole for said fixing member formed at an end part of an adhesive agent flowing-out side of said rod-like member;

feeding adhesive agent from an adhesive agent flowing-in side of a hollow part of said rod-like member, flowing out said adhesive agent from the adhesive agent flowing-out side of said rod-like member, filling the adhesive agent to a clearance between the exterior surface of said connector and inner walls of said connection holes of said structural members and returning the adhesive agent to the adhesive agent flowing-in side.
