Abstract
A beam flange clamp includes a clamp body having a first vise jaw portion with a first gripping surface and a second vise jaw portion with a second gripping surface. The first gripping surface and the second gripping surface are oriented parallel to each other, are facing the same direction and are offset in height by a predetermined clamping distance. The at least one bolting hole is formed through the first vise jaw portion perpendicularly to the first gripping surface.
Claims19
A structural beam joint, comprising:
- a first structural beam having a web portion and at least one first flange portion;
- a second structural beam having at least one second flange portion, the second structural beam having an axis of extension being angled with respect to the axis of extension of the first structural beam and intersecting with the first structural beam;
- at least one beam flange clamp comprising:
- a clamp body having a first vise jaw portion with a first gripping surface and a second vise jaw portion with a second gripping surface;
- wherein the first gripping surface and the second gripping surface are oriented parallel to each other, are facing the same direction and are offset in height by a predetermined clamping distance;
- and
- wherein at least one bolting hole is formed through the first vise jaw portion perpendicularly to the first gripping surface;
- and
- at least one fastening pin or bolt inserted in the at least one bolting hole of the at least one beam flange clamp,
- wherein the at least one first flange portion of the first structural beam abuts the at least one second flange portion of the second structural beam, and
- wherein the at least one fastening pin or bolt tightens the clamp body of the at least one beam flange clamp to the first flange portion of the first structural beam so that the first gripping surface of the at least one beam flange clamp presses against the at least one second flange portion of the second structural beam and the second gripping surface of the at least one beam flange clamp presses against the at least one first flange portion of the first structural beam.

A method for forming a structural beam joint, the method comprising:
- abutting a first flange portion of a first structural beam to a second flange portion of a second structural beam, the second structural beam having an axis of extension being angled with respect to the axis of extension of the first structural beam and intersecting with the first structural beam;
- pressing a first gripping surface of a beam flange clamp which comprises a clamp body having a first vise jaw portion with the first gripping surface and a second vise jaw portion with a second gripping surface, the first gripping surface and the second gripping surface being oriented parallel to each other, facing the same direction and being offset in height by a predetermined clamping distance, to the second flange portion of the second structural beam and pressing the second gripping surface of the beam flange clamp to the first flange portion of the first structural beam;
- introducing a fastening pin or bolt in a bolting hole being formed through the first vise jaw portion perpendicularly to the first gripping surface of the clamp body of the beam flange clamp;
- and
- tightening the second gripping surface of the beam flange clamp to the first flange portion of the first structural beam and the first gripping surface of the beam flange clamp to the second flange portion of the second structural beam by the fastening pin or bolt.

- and
- wherein at least one bolting hole is formed through the first vise jaw portion perpendicularly to the first gripping surface;
- and
- at least one fastening pin or bolt inserted in the at least one bolting hole of the at least one beam flange clamp,
- wherein the at least one first flange portion of the first structural beam abuts the at least one second flange portion of the second structural beam, and
- wherein the at least one fastening pin or bolt tightens the clamp body of the at least one beam flange clamp to the first flange portion of the first structural beam so that the first gripping surface of the at least one beam flange clamp presses against the at least one second flange portion of the second structural beam and the second gripping surface of the at least one beam flange clamp presses against the at least one first flange portion of the first structural beam.
