Structural steel clamped joint

Abstract

A joint for structural steel is provided which connects a pair of parallel beams in end-to-end relationship with a second pair of parallel beams. The beams are of any cross-sectional form having an L-shaped component, for example an inverted "S." The beams are retained in a U-shaped channel having two upstanding side walls and a bottom wall connecting the side walls. The bottom wall is provided with one or more centrally located holes. The joint is formed by nesting two pairs of parallel beams in end-to-end relationship within the U-shaped channel. The width of the channel is such that the seating bases of the L-shaped beams do not obstruct the holes in the bottom wall of the U-shaped channel. A clamping plate having holes aligning with the holes of the bottom wall of the channel is fitted into the channel over the seating bases of the beams. Means, such as a nut and bolt, are used to bind the clamping plate onto the U-shaped channel. The clamping plate thereby pushes the beams outwardly against the side walls of the U-shaped channel and downwardly against the bottom wall of the channel.
