concrete form used in the pouring of concrete to a structural pier
or column until the concrete has cured at which time the adjustable
concrete form hanger and concrete form are separated from the
structural pier or column, the adjustable concrete form hanger
comprises a hanger bracket coupled to an anchor stud or other
attachment element embedded or welded to the pier or column by a
first coupler and coupled to the concrete form by a second coupler
such that the anchor stud, first coupler, hanger bracket and second
coupler are symmetrically aligned in a vertical plane whereby the
weight of the concrete form and poured concrete exerts minimal
torsion force on the adjustable concrete form hanger in the
vertical plane.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] An adjustable concrete form hanger to temporarily couple a
concrete form used in the pouring of concrete to a structural pier
or beam until the concrete has cured at which time the hanger and
concrete form are separated from the structural pier.
[0003] 2. Description of Prior Art
[0004] Various structures and methods of temporarily supporting
concrete forms have been developed. For example, hangers may be
used to straddle to the top flange of beams and connected to forms
by bolts or other connectors. One common method is referred to as
the needlebeam and consists of a structural steel or timber beam
hung from the bottom flange of the outside beam, extending out
under the overhanging slab and under the adjacent interior beam for
reaction.
[0005] The common method employs a structural steel bracket
suspended by a bolt, usually at a 45 degree angle, from a hanger
anchored to or installed to straddle the top flange of the exterior
beam.
[0006] U.S. Pat. No. 4,660,800 shows a hanger and bracket for
supporting form work for steel and concrete during the curing stage
of a bridge deck overhang. 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 is
removed for reuse.
[0007] U.S. Pat. No. 3,472,475 describes a bridge overhang bracket,
attachable to a flanged girder for supporting concrete forms and
catwalks a horizontally aligned support beam the web of the flanged
girder. Protruding upwardly from the top of the support beam near
abutting end is a cylindrical boss which abuts against a flange of
the flanged girder. An inclined dual bolt hanger extends from the
clips welded on the girder flange to a stirrup on which the
underside of the support beam rests.
[0008] U.S. Pat. No. 5,104,089 shows a concrete supporting bridge
overhang bracket system which can be lifted and transferred in gang
fashion from a first section of a bridge to a subsequent section.
The system includes a series of longitudinally spaced apart
laterally extending overhang brackets to which concrete forms are
secured. A lift bracket assembly is attachable to a pair of
overhang brackets and can be clamped to the deck to support the
overhang brackets and the forms from the deck so that the brackets
can be disconnected from the deck. Once disassembled, the lift
bracket assembly can be supported by a crane and unclamped from the
deck, the crane thereafter moving the lift bracket assembly, the
overhang brackets and the forms to the subsequent section.
[0009] U.S. Pat. No. 3,806,074 relates to forms for molding
concrete on horizontal I-beams. The forms are adjustable from a
position above the beams. With respect to the interior space
between two beams, clips and/or hangers suspend bolts adjacent the
beams, the bolts being threadably engaged with brackets between
which extends a joist located below and in overlapping relation
with the upper flanges of the beams. The bolts are rotatable from a
position atop the beams to adjust the brackets to control the
locating of the joist. Sheeting supported on the joist support a
mold for wet concrete.
[0010] U.S. Pat. No. 5,092,559 teaches a concrete form support
assembly for forms used to pour concrete for bridge floors. Such
forms include a plywood flooring supported at a desired uniform
depth relative to the plane of the upper surface of the bridge
beams. The plywood flooring is supported by ledgers which extend
laterally between the bridge beams and stringers on the top thereof
which extend longitudinally and parallel with the bridge beams. The
ledgers are supported by vertical bolts hanging from hanger bars on
each side of each bridge beam, with support plates at the lower end
of the vertical bolts to support opposite ends of the ledgers, and
threaded nuts below the support plates to adjust the plates and
ledgers thereon up and down. After the plywood flooring has been
put in place, workmen cannot thereafter reach the adjusting nuts
from above to make final depth adjustments of the flooring. The
support assembly in accordance with the present invention provides
depth adjustable hanger bolts adjustable from above the plywood
flooring after it has been put in place.
[0011] U.S. Pat. No. 5,524,854 shows a structural supporting system
for the use as a temporary support in concrete overhang
construction and for the use as a support in concrete slab truss
construction. The structural supporting system includes a series of
support beams and a plurality of support brackets positioned along
the length of the support beam. A support bracket is provided at
the opposite ends of the support beam for the suspended support of
the support bracket to increase or reduce the span of the support
beams. A series of cooperating brackets are positioned intermediate
the support brackets to support of one support bracket in the
concrete overhang falsework construction. A series of cooperating
brackets are positioned intermediate to the support brackets for
the support of two support brackets in the concrete slab falsework
truss construction. The support bracket or brackets include
adjustable upper and lower opposing gripping surfaces for engaging
corresponding upper and lower surfaces of the support beam in
adjustable mounting relationship thereto. The brackets include an
integral attachment pin to secure the support beams to the support
bracket for attachment of the support bracket to a fastener
suspended from the concrete overhang form construction and the
concrete slab falsework truss construction.
[0012] U.S. Pat. No. 6,273,393 shows a concrete form support
bracket assembly used to pour concrete bridge decks or building
floors. The brackets, which are used in pairs, have a base plate to
bear the weight of form ledgers, a rear wall extending from the
base plate, and a pair of spaced apart side walls extending from
the rear wall and base plate. A fastener is provided for securing
the ledger in the bracket and an opening is located in the base
plate for providing a bolt to support and adjust the bracket. In
the assembly form, the bracket may include a hanger bar, receiving
channel and adjustable bolt as a support for the bracket.
