Abstract
Abstract A support for the framework which supplies the base for a roadway for a bridge or the like, and a method of installing, in which the support includes a tie beam extending transversely beneath the framework and includes connectors to connect the beam and framework together. A column is pivotally connected to the beam at each end so the beam can be rotated about the longitudinal axis thereof whereby the beam can support an inclined roadway while the columns extend vertically downwardly to the ground. The point of connection of the beam to each column is adjustable along the columns and will also permit the columns and beam to tilt relatively in the common plane thereof. Each column has a base member on the bottom which may be tiltable on the respective column. The pivotal connection of the columns to each end of the beam permit the practice of a method of installing in which the beam and columns are moved longitudinally beneath the framework with the columns generally horizontal to the plane of use of the beam whereupon the colunmns are pivoted downwardly on the ends of the beam to place the lower ends of the columns on the ground and the beam is then adjusted upwardly on the columns into load bearing engagement with the underneath side of the framework. Installation carriages moveable along the top of the framework support the tie beams and columns during installation.
