Abstract
Abstract A shoring bracket for overhead form work has a support head engageable with a form work beam. The head is vertically adjustable for positioning of the form work. The head of the bracket includes a roller engaging the form work beam and a lock for the roller to prevent rotation thereof when the head is supporting the form work. The roller is unlocked for longitudinal rolling of the form work beam over the roller for removal of the form work.
