US 5,755,981 A · Bridge overhang system for connecting forms from above a girder beam

Abstract

A bridge overhang system which enables forms to be secured to a bridge girder member without the necessity of a construction worker standing under the girder to secure the form to the girder. More particularly described, a funnel bracket unit connected to the form has guide surface which enables a hanger rod to be guided to a securing member of the overhang bracket unit from above the girder member. The system of the present invention has a support beam with an opening defined therein, a retainer positioned along a surface of the support beam at the opening; and a support rod extending through the support beam to the retainer. The support rod connectably engages the retainer upon insertion of the support rod to the retainer. Additionally, the retainer may include a bracket having a plurality of sides with at least one of the sides being operable for connection to the form to provide support for the form. An engagement member may be positioned between the sides and serve to engage the support rod extended into the engagement member to provide support from the support beam. A guide surface may extend between the sides of the bracket to the engagement member. Preferably, the engagement member is a threaded nut and the guide surface is preferably shaped like a funnel.

Dependent claims

A system for hanging a form from a support beam used in bridge construction, comprising:

a bracket unit;
a support beam operative to support said bracket unit for hanging a form and having an opening defined through said support beam;
a retainer operative to secure said bracket unit for hanging said form, said retainer being positioned along a surface of said support beam at said opening;
a support rod extending through said opening of said support beam to said retainer, said support rod connectably engaging said retainer upon insertion of said support rod from the direction of said support beam to said retainer;
said bracket unit having a plurality of sides.
at least one of said sides being operable for connection to said form to provide support for said form;
an engagement member positioned between said sides, said engagement member adapted to engage said support rod extended into said engagement member to provide support from said support beam;
a guide surface connected to one of said sides and extending between said sides of said bracket to guide said rod toward said engagement member;
guide edges extending from the side of said guide surface;
a guide bracket defining a cavity for slidably engaging said edges of said guide surface, said guide bracket having an opening defined therein;
and
said edges of said guide surface being positioned within said cavity such that said support rod may extend through said opening to said engagement member, and said engagement member being adjustable via said edges.
