Description
RELATED APPLICATIONS
[0001] This application is a division of U.S. patent application
Ser. No. 13/613,444 filed Sep. 13, 2012, which claims the benefit
of U.S. Provisional Application Ser. No. 61/534,630 filed on Sep.
14, 2011, the contents of both of which are hereby incorporated by
reference in their entirety.
FIELD
[0002] The invention relates to a construction hanger for use in
assembling concrete forms and, more particularly, tying the form
members to a construction support member such as an I-beam. This
invention provides an attachment of overhanging brackets,
scaffolding, or other accessories to steel, concrete, or other
bridge beams or construction support members.
BACKGROUND
[0003] In order to construct concrete sections of roads, bridges,
buildings, or other components, a form is provided into which the
concrete is poured and allowed to harden. These forms may take on a
variety of shapes and configurations according to the use that
they're put.
[0004] In creating overpasses, standing walls, or other sections, a
framework of steel girders, I-beams, or other supporting structure
is assembled before pouring the concrete to provide a structure
from which to assemble the form. The form is supported on the
girders or I-beams by means of construction hangers that support
the weight of the form and concrete by distributing the load into
the girder. Because the hangers may support the forms from within
the volume of the form, they are usually unrecoverable after the
concrete has been poured and allowed to harden. Therefore, it is
preferable to provide economical hangers that can be inexpensively
replaced as hangers are consumed.
[0005] These hangers may also be used to support scaffolding or
other accessories to support structure.
[0006] An example of one prior art hanger generally includes a
brace and a guide welded together to form the hanger. The brace may
be formed from a steel bar bent around a beam flange to form a hook
while the guide, which may be formed from a piece of stamped and
bent steel, is welded to the bar opposite the hook. A support rod
may be inserted through the guide and a form is attached to the
support rod. By way of example, the support rod may be a threaded
rod held in place by a hex nut or the like.
SUMMARY OF THE INVENTION
[0007] According to a first aspect of the invention, a construction
hanger comprises a brace or bracket formed or cut from a
substantially flat metal plate and an arm extending from its distal
end and a proximal end. where a guide having a channel is
positioned and bonded or formed onto the brace. The term "brace" as
used herein refers to that portion of the hanger 10 that engages
the construction support member such as an I-beam. The term
"hanger" refers to the brace in combination with the guide member
that receives the hanger rod that ties the form to the support
member. The term "hanger" does not include the rod itself.
[0008] According to one variation of the first aspect of the
invention, the brace includes an arm that is shaped to receive
and/or engage a beam profile. The beam profile may be the profile
of any of a variety of construction elements such as a square or
tapered I-beam, a C-channel beam, a square beam, an angle-beam, or
other type of beam that is well known to those having skill in the
art.
[0009] According to another variation, the guide member is bonded
to the brace by means of welding, one or more fasteners, an
interference fit, or other technique known to those having skill in
the art. The guide member may have a variety of constructions,
including but not limited to a round tube, a square tube, and a
U-channel. The function of the guide is to retain the hanger rod by
which form members are tied to the construction supports.
[0010] According to yet another variation, the guide includes a
major axis that is at an angle to the brace. For example, the angle
between the major axis and the brace may be at or about 45.degree..
Other arrangements and angles are also anticipated, for example the
angle between the clip and the brace may be 90.degree., and the
brace and the guide need not be in the same plane.
[0011] According to yet another variation, the brace may include a
bearing surface or extension that is typically triangular in shape
at the proximal end of the brace to which the guide member is
bonded.
[0012] In a second aspect of the invention the hanger includes one
or more bearing plates. These bearing plates are optionally
positioned on an underside of the brace and may be positioned
between the distal and proximal ends. The bearing plates are
positioned between the retainer or flange and the beam to provide
surface area for load distribution. Alternatively, the bearing
plates may be positioned on the upper surface of the arm forming
the brace.
[0013] Another aspect of the invention is a novel method for
forming the hanger in accordance with the above-described aspects.
A substantially flat sheet of material, for example plate steel, is
provided. A brace is cut from the material, the retainer having a
distal end with a flange having a profile approximately
complementary to a beam profile so that when attached to the beam
profile the retainer fits accurately and tightly to the beam
profile. A guide is provided and may include a circular, square, or
U-shaped cross section. The guide is bonded to the brace at a
proximal end of the retainer. The angle between the guide and
retainer may be approximately 45.degree..
[0014] According to another variation, one or more bearing plates
may be provided. These bearing plates are bonded to the brace in a
perpendicular arrangement so as to distribute the load between the
retainer and a beam to which the hanger may be attached. The
bearing plates may be attached to the flange or directly to the
brace and may either protrude to form a bearing surface
corresponding to the beam profile or may be flush with a bearing
surface of the brace.
[0015] Another aspect of the invention is a novel method for using
the hanger in accordance with the above-described aspects.
According to this aspect, a hanger is provided comprising a brace
cut from a sheet of material and having an arm having a profile
corresponding to a beam profile and a proximal end having a guide
member. The hanger is provided on a beam having the beam profile
such that the flange engages the beam profile to prevent movement
along the length of the retainer or about an axis parallel to the
major length of the beam. A support rod is provided that engages
the guide. A load may then be applied to the support rod so that
the force is transmitted axially through the support rod to the
guide and subsequently to the retainer and beam.

DETAILED DESCRIPTION
[0022] FIG. 1A illustrates a partial view of a hanger 10 in
accordance with one embodiment of the invention wherein the hanger
includes a circular tube 12 that functions as a guide member for
the hanger rod that is assembled with the hanger to assemble a
concrete form member with a construction support member such as an
I-beam. FIG. 1B on the other hand illustrates an embodiment in
which the guide member is a square tube 14 and FIG. 1C illustrates
an embodiment in which the guide member is a U-shaped channel
member 16. In each embodiment, the guide member 12, 14 or 16 is
carried on a brace 20 including an elongated bar 22. The bar
terminates in an end surface 26 (FIG. 2). In the illustrated
embodiment, the bar 22 is formed with a triangular extension 28
which provides additional support for the guide member and
distributes the forces acting on the guide member over a longer
lineal surface.
[0023] FIG. 2 illustrates four embodiments (FIGS. 2A-2D
respectively) for brace members 10 that can be used in constructing
a hanger in accordance with various embodiments of the invention.
The brace member 20 includes an elongated bar 22 from which an arm
24 extends. The arm 24 extending from the elongated bar 22 is
shaped to engage a construction support member as discussed in more
detail below. The brace 20 includes a sloped end surface 26 which
can be bonded to or formed into a guide member such as members 12,
14 and 16 illustrated in FIG. 1. FIG. 2 illustrates an embodiment
of the invention in which the guide member is carried on the sloped
end surface 26 that is in the same plane as the brace member 20. It
is not essential that the hanger be constructed in this fashion.
The end surface could be formed such that the guide member is
located in at any desired angle with respect to the brace member
within or out of the plane of the plate forming the brace 20. In
the embodiment shown in FIG. 2, the brace members 20 each include a
bearing extension 28 which is generally triangular in shape (note
the dotted lines) and which further extends or widens the surface
30 of the elongated bar 22 and the end surface 26. This facilitates
bonding the guide member to the brace 20 and distributes forces
over a larger surface area.
[0024] FIG. 3 illustrates an embodiment of the invention in which a
tubular guide 12 is bonded to the brace 20 by a weld line 32.
However, those skilled in the art will appreciate that other
techniques than welding may be used to bond and/or form the guide
member 12 on the end of the brace 10. The guide member can be
formed separately and bonded to the brace 20 using an adhesive or
weld, or the guide member can be a metal formed extension of the
brace member 20 and the guide member is formed by bending the metal
of the brace member. In this embodiment, there is no end surface 26
as shown in the embodiments of FIG. 2. Instead the metal plate
forming the end of the brace 20 would be formed into a tube.
[0025] FIG. 7 illustrates an example of the hanger 10 in position
on an I-beam 36. The arm 25 includes a right angle extension which
receives the rectangular shape or profile of the I-beam. A threaded
hanger rod 38 is inserted in and through the guide member 12 and
retained by a threaded nut 40. The rod member engages the
construction form and ties or hangs the form in position from the
the I-beam thereby transferring load from the support rod to the
hanger and the beam.
[0026] FIGS. 4-6 illustrate embodiments of the invention in which
hanger 10 includes one or more bearing plates 42. In FIG. 4 the
hanger is an assembly of rectangular plate members as shown which
form a rectangular opening in the brace member similar in shape to
the hanger illustrated in FIG. 3 which is formed from a cut metal
sheet. The bearing plate 42 is situated on the lower portion of the
arm 44 in this embodiment. In FIG. 5, two bearing plates 42 and 42'
are attached to the lower surface of the elongated member 22 of the
brace 20. These bearing plates function to distribute the forces
that are acting on the hanger over a larger surface area of the
construction support member to prevent damage or premature failure
of the support member. FIG. 6 illustrates an embodiment in which
the bearing plate 42 is received in a cutout 46 in the elongated
bar 22 forming the brace 20. Alternative arrangements of bearing
plates are also contemplated. For example, a single bearing plate
may be utilized to engage the beam along the entire or major
portion of the length of the brace. Alternatively, multiple bearing
plates may be provided along the length of the brace. Finally, the
retainer and flange may be constructed from components having an I-
or T-shaped profile so that the bearing plate is integrally formed
with the hanger.
[0027] FIG. 8 illustrates another embodiment of the invention in
which the hanger is formed from a plate 60 optionally having
apertures 66 therein. The plate 60 is rectangular in shape and has
a pair of tubular guide members 68a and 68b extending from each of
its side edges. A pair of hanging rods 70a and 70b are inserted
through the guide members and retained by threaded nuts 72a and
72b. Optional bearing plate 62 extends from a cutout in the bottom
edge of the plate 60 such that the hanger is stabilized on the top
of the I-beam 36.
[0028] Representative examples of construction support members with
which hangers of the embodiments of the invention may be used
include but are not limited to (a) an I- or T-beam; (b) a square or
C-beam; (c) an I- or T-beam having a tapered top plate; and (d) any
other type of beam having a square edge, including an I-beam,
T-beam, C-beam, square beam, and angle beam. These variations are
only proposed illustrations and are not intended to be
limiting.
[0029] FIGS. 1A-1C show various embodiments of the guide (or tube)
that may be used to engage and hold the support rod. According to
these embodiments, the guide may be a round tube (top); square tube
(middle); or C- or U-Channel (bottom). These embodiments are
provided as illustrative and not intended to be limiting. For
example, the guide may include an angle, hexagonal, or other shaped
channels for accommodating a support rod. Alternatively, the
support rod may be integrally formed with the hanger.
[0030] In FIG. 3, the guide has been bonded to the brace by means
of a fillet weld. However, it should be appreciated that other
means of attaching the clip and braces together are anticipated.
For example, the means may include bonding by an adhesive, tac or
other type of weld, or other type of joint. Alternatively, the
means may include physical attachment, including without
limitation: screws, straps, interference fit, or other mechanical
interface. Further, the guide may be integrally formed with the
brace either in a finished state or additional machining, such as
bending a guide to form a tube, may be performed to provide the
guide. Further shown in FIG. 3 is that the brace may be cut from
1/4'' steel plate.
[0031] FIGS. 5-7 show various alternative embodiments of the
hanger, including the arrangement of the flange section and
placement of optional bearing braces. The top (hereafter "FIG. 5")
and middle (hereafter "FIG. 6") illustrations show the flange as a
separately formed component formed from a number of flat bars which
may be bonded (e.g. welded) or mechanically attached (e.g. screwed)
to one another. The advantage of these arrangements is that the
flange may be manufactured from several sections of steel bar. The
bottom illustration (hereafter "FIG. 7") shows the flange according
to the embodiments illustrated in e.g. FIG. 2 as a single piece cut
from a sheet of material, e.g. 1/4'' steel plate. The advantage of
this arrangement is that the number of steps for manufacture is
reduced and the single-piece construction may be preferred to a
welded multiple-piece construction in some applications.
[0032] FIG. 8 also illustrates several variations of the location
of bearing plates. As shown in FIG. 5, a single bearing plate is
illustrated. This bearing plate is located on the portion of the
flange that would engage the underside of an I-beam or similar.
FIG. 6 illustrates two bearing plates that may be positioned at the
proximal and distal ends of the brace and would engage the top
plate of an I-beam or similar. FIG. 7 illustrates that a single
bearing plate may be positioned at the proximal end (adjacent the
guide) to engage the top of an I-beam or the like. Also shown in
FIG. 5 is that the bearing plates may be either flush with or
protruding from the profile of the brace and flange. FIG. 6 shows
the bearing plates extending from the brace so that the bearing
plates would contact the beam and the plate would not. FIG. 7 shows
that the bearing plates may be recessed so that the load is shared
between the bearing plates and the brace. In the first instance, it
is necessary to design the profile of the brace and flange to
account for the increased spacing between the brace and flange.
[0033] Having described the invention in detail and by reference to
specific embodiments thereof it will be apparent that numerous
variations and modifications are possible without departing from
the spirit and scope of the disclosure.
