A first beam (1) is inserted through a transverse opening (4) in a tubular second beam (2). A bolt (7) is inserted through unthreaded holes (9A, 9B) in the second beam. The bolt may be transverse to both beams. A wedge (5) is threaded onto the bolt inside the second beam (2). Tightening the bolt moves the wedge against a side of the first beam, forcing it against surfaces (11, 12, 13) of the transverse opening (4) opposite the wedge. The bolt counters the reaction to this force. The beams can be formed as extrusions. The joint only requires machining for the transverse opening (4) and smoothbore bolt holes (9A, 9B) for a single bolt. The second beam may have a rectangular cross section with relatively thicker corners (2A-2D) and thinner mid-walls (2E-2H).
