Abstract
A ledger truss for scaffolding has a first ledger and a second ledger, each ledger having a longitudinal axis and being of uniform generally 'I' shape in cross section along its length. A clamp bracket joins the first and second ledgers end to end at a butt joint with their axes aligned. The upper end of a vertical strut is attached to the clamp bracket, and an end bracket is attached to the end of each ledger remote from the clamp bracket. At least one first tensioned tie bar joins the end bracket on the first ledger to the lower end of the vertical strut, and at least one second tensioned tie bar joins the end bracket on the second ledger to the lower end of the vertical strut.
