This is a double-sided shear connection. A dangerous situation can arise when filler beams frame into opposite sides of a girder and share the same holes in the girder web. One way to avoid this is to offset the beams. Another solution is shown here; simply add an extra bolt beyond those needed to carry the shear. This extra bolt, at the bottom of the connection, goes through only one set of double angles and can be used to hold the right-hand beam temporarily in position until the left-hand beam is fitted up, then all the bolt-holes can be filled.
