Abstract
A hanger and bracket attached to the hanger for supporting formwork for steel and concrete during the curing stage of a bridge deck overhang is described. A hanger attached to the beam of the bridge supports a connector carrying the bracket. The connector is maintained in a substantially vertical position. The bracket is adjustable in both horizontal angle and in grade because of pivotally attached horizontal members, an adjustable compression leg, and connector means. Once the cement is set the bracket may be recovered for reuse.
Claims21
A bracket for supporting a deck outside a beam, attached to the beam by a hanger means, said bracket comprising:
- a horizontal section composed of:
- a first horizontal member rigidly attached to said hanger means by a substantially vertical connector means;
- a second horizontal member pivotally connected to, and disposed in adjustable angular relation with, said first horizontal member;
- means for adjusting the angle of said second horizontal member with respect to said first horizontal member;
- and
- bearing means in bearing engagement with the wall of said beam below said first member and said second member and interconnected with said first member and said second member for supporting part of the load on said bearing deck.
In combination with a bracket for supporting forms for pouring concrete on a bridge overhang, a hanger for attaching the bracket to a beam to support forms for pouring concrete which comprises:
- a means for anchoring a first end of a load bearing member to the beam;
- a load bearing member having a first end attached to the beam and a second end adapted to receive and retain a connector with a substantially vertical longitudinal axis having a central bore therethrough;
- and
- a means for securing the bracket to said connector such that the bracket and connector may be removed from the beam without damaging the poured concrete.
A method for positioning an overhang support bracket on a beam having a top horizontal surface and inner and outer vertical surfaces comprising the steps of:
- hanging said bracket upon a hanger attached to the top of the beam by placing a nut on a bolt passing through the bracket, connector and the hanger and allowing said bracket to rest against, and parallel to, the outer surface of the beam;
- attaching a lever bar tool to a lug on said bracket and raising said bracket to a substantially horizontal position using the top of a hanger bolt as a fulcrum;
- rotating said bracket with said attached lever bar to a position horizontally outward of, and substantially perpendicular to, the beam such that the top surface of the beam and the top of said bracket are in substantially the same horizontal plane;
- securing said bracket in place to said hanger by tightening said nut;
- and
- removing the lever bar tool.
