Mobile outrigger scaffolding system
Abstract
This invention contemplates a combination and method involving
mounting specially designed plates and/or mounting apparatus
against and on the standard vertical column used in construction of
office structures or other structures including bridges. The plates
have a clamping mechanism designed to fit around or on the vertical
column. A lower and upper plate are mounted. The plates have a
protrusions onto which are mounted a bracket with holes fitting on
the protrusions. The bracket is secured with a cotter pin. The
brackets project outside the eventual skin of a building and deck
planks or pics can be mounted on the brackets. The mobile outrigger
scaffolding system allows workmen to safely walk and work on the
deck planks to perform work on a floor-by-floor basis. The system
can be dissembled quickly and moved to another part of the same
floor, to a new floor, and can be used around the outside corner of
a structure or from an overhang or from a horizontal beam. The
invention is uniquely designed for steel tube construction. A small
part of fireproofing can be removed, the invention utilized and the
fireproofing replaced.

Description
[0001] This invention is a continuation-in-part of Provisional
Application No. 60/173,408 filed on Dec. 28, 1999 by inventor Terry
W. Cogar entitled "A Mobile Outrigger Scaffolding System," and of a
Provisional Application filed on Dec. 26, 2000 also called a Mobile
Outrigger Scaffolding System as to which a serial number has not
yet been assigned.
FIELD OF INVENTION
[0002] This invention primarily relates to the construction
industry, especially to buildings that have a structural skeleton
with floors, after which phase of construction exterior surface and
windows are added. Present technology necessitates the building of
scaffolding on the exterior of the structure, often from the ground
up. The present invention creates a mobile system mounted on the
structural skeleton that furnishes outriggers exterior to the floor
and proposed skin of the building, upon which deck planks can be
placed, enabling workers to quickly and efficiently access the
exterior of the building with construction material, mount or apply
the material, and then dismantle the mobile outrigger system and
move to a different location on the building. The system is
flexible in design to allow work around the exterior corner or edge
of a building, or from a horizontal overhang or beam. Once the deck
planks and rails are in place, the worker has no need to climb up
traditional scaffolding to reach the desired level. The stability
and access to the mobile outrigger scaffold in inclement weather or
adverse ground conditions is significantly better than traditional
ground-up scaffolding and lessens environmental impact adjacent to
the structure.
BACKGROUND OF INVENTION
[0003] The prior art of most note is well-known and involves the
preparation of ground-up scaffolding. Such scaffolding requires a
stable surface, and if built from the ground-up, requires access
from the ground which is inconvenient in inclement weather
conditions. If mounted up the side of a building, substantial
effort requiring ample time to assemble and dissemble, and normally
requiring welding, is required if scaffolding is to be based from a
floor or stage above ground level.
[0004] The assembly of scaffolding itself has risks to workers from
failure or falling objects from higher levels of scaffolding. The
present invention minimizes any risk in assembly of the mobile
outrigger scaffold to the building because a worker is not outside
of the building. The setting of deck planks on the outrigger
brackets requires attention to safety, but once the deck planks and
rails are in place, the worker has no need to climb up scaffolding
to reach the desired level. The stability and access to the mobile
outrigger scaffold in inclement weather or adverse ground
conditions is significantly better than traditional ground-up
scaffolding and lessens environmental impact adjacent to the
structure.

DESCRIPTION OF INVENTION
[0015] The essence of one preferred mode of the invention begins
primarily for vertical column structures with a flat plate that has
ends shaped like C-folds on the shorter edges of the plates, as
opposed to the longer edges, as in FIG. 1. A line perpendicular to
the longer edges will be oriented vertically. A line perpendicular
to the shorter edges of the plates will be oriented horizontally
and will be a horizontal axis. The plate may be formed, cast or
forged. A typical plate would have shorter edges 6-8 inches long. A
typical H-beam is 9 inches wide on the end face of a vertical
H-beam.
[0016] This preferred mode of the invention uses the edges of a
vertical column in the shape of an H-beam standing on end as shown
in FIGS. 2A-2D. The ends of the flat plate are shaped like a C-fold
which C-fold has an inside perimeter which can fit around the edge
of a vertical column H-beam. The distance between C-folds should be
sufficient so that when one C-fold is situated on one edge of a
face of an H-beam, the other C-fold with a clamping mechanism
inside can be situated around the opposite edge. Inside at least
one of the C-folds is a clamping mechanism, normally consisting of
a metal piece, which could have an indentation in it and would be
driven by a screw mounted through the C-fold. The clamping
mechanism can be a nut welded to a screw to grip with a wrench,
which screw passes through a nut welded or embedded in the C-fold
through which the screw passes to a mechanism with a rotationally
flexible or weaker end so the screw can put pressure on a clamp
face applied to the edge of an H-beam. A levered clamping mechanism
could also be employed to direct force against a beam and pull the
opposite C-fold securely against the vertical H-beam as shown in
FIGS. 1 and 5.
[0017] When the plate is set facing on the vertical H-beam with the
C-fold edges cupped around cupped around the end face of the
vertical H-beam, the clamping mechanism is tightened, and one
C-fold is pulled more tightly into the beam while the C-fold with
the clamping mechanism grips the opposite side resulting in a
firmly mounted plate on the vertical H-beam.
[0018] From this basic plate design, the best mode of the invention
works in two parallel ways. In the first mode, if the center
section of a vertical H-beam is basically parallel to the proposed
outer curtain wall of a building, the best mode is the use of a
plate with perpendicular cylindrical protrusions supporting a
bracket as in FIGS. 1 and 5. In the second mode, if the center
section of a vertical H-beam is basically perpendicular to the
proposed outer curtain wall of a building, then the best mode is
the use of three plates also referred to as a triad of plates.
[0019] For proceeding around the corner of a building, assuming for
the moment the center sections of all vertical H-beams are oriented
in the same direction, then a combination of the first and second
modes is appropriate.
[0020] The basic support plate for the first mode has on it two
cylindrical protrusions which will be opposite the side of the
plate placed against the H-beam as shown in simplest form in FIG. 1
and more complex from in FIG. 7. These cylindrical protrusions may
be smooth protrusions to facilitate a support bracket or deck
bracket being slid on the protrusions. Normally, a retaining pin on
the protrusion would prevent the support from sliding off.
Alternatively, the protrusion could be a bolt. Normally, a
retaining pin or a nut on the protrusion that is a bolt would
prevent the support from sliding off. Ridges or notches could be
used to prevent the support from sliding off.
[0021] One of these support plates mounted on an H-beam then has a
horizontal bar with holes in it mounted so the horizontal bracket
protrudes out from the plate mounted on the H-beam. The horizontal
bracket is then exterior of a proposed outer curtain wall of a
building. The bracket can have a deck plank placed on it and
functions as a walkable deck in combination with another plate on
the next H-beam over in a building. Similarly, two plates, over and
under, with one protrusion could be used. However, for safety
reasons, it is preferable to use two plates on each H-beam, each
with two perpendicular protrusions and use a bracket type of
support on each set of two plates on each H-beam. A bracket type of
support could be an upper horizontal bar with holes for the
cylindrical protrusions on the interior end of the upper horizontal
bar with a lower angle bar with a horizontal end having holes
underneath the upper horizontal bar holes, with the angle bar
supporting the outside end of the upper horizontal bar. This can
also be referred to as a deck support. Further bracing can be put
on the bracket type of support. The horizontal bar or the bracket
type of support would normally have an upturned end to prevent a
deck plank from inadvertently sliding off which upturned end is
opposite the end with the holes to mount the bracket type of
support on the protrusions on the plate as seen in FIG. 5. Two sets
of two plates with bracket type of supports on adjacent vertical
H-beams, and a deck plank placed on them, and a restraint on the
protrusions provide a stable, mobile outrigger scaffold with deck
plank which permits access to the exterior of a building to conduct
activities on the outside of the building such as installing
curtain wall, windows, painting and the like as seen in side view
of a mounted bracket in FIG. 5.
[0022] The invention recognizes that not all vertical H-beams will
be oriented with the center section parallel to the curtain wall.
For vertical H-beams with the center section generally
perpendicular to the curtain wall, the second mode and a set of
three plates using a plate somewhat like the first plate and a
modified set of two other plates is used as illustrated in FIG.
3.
[0023] In the second mode, again starting with the basic plate
design, a support plate is used. This plate has cylindrical
protrusions mounted on one end parallel to the horizontal axis
which will be called support protrusions. These protrude from the
edge of the plate adjacent to the C-folds. The support protrusions
are thus parallel to the flat surface of the plate. When the plate
having the C-fold shaped ends is mounted on the vertical H-beam
with the center section perpendicular to the curtain wall, the
support protrusions run parallel to the proposed curtain wall. A
first support plate is mounted on the outside face of such a
vertical H-beam, and a second support plate is mounted on the
inside face of such a vertical H-beam, by tightening the clamping
mechanisms.
[0024] For the second mode, a third support plate, also referred to
as a bracket plate, as shown in FIG. 4, is made with apertures in
it adjacent to the short edges of the plate to accommodate the
support protrusions of the first and second plates. This third
support plate would normally not need to have C-folds or a clamping
mechanism. The third support plate would have cylindrical
protrusions perpendicular to the flat surface of the plate.
[0025] The support protrusions of the first and second plates are
shown in top view in FIG. 6 and side view in FIG. 7; if the first
and second plates have cylindrical protrusions perpendicular to the
flat surface of the plate, as in FIGS. 6 and 7, the plate is more
versatile and can be used as the plate in the first mode of the
invention, and the deck bracket mounted on the cylindrical
protrusions.
[0026] By placing the first of these three plates on the face of
the vertical H-beam, and mounting it as before, and placing the
second plate on the opposite face of the vertical H-beam, and
mounting it as before, and placing the third support plate on the
support protrusions, the concave portion of the vertical H-beam is
spanned by the third support plate, and protrusions exterior to the
outline of the vertical H-beam are presented and available on which
to mount the bracket type of support which will protrude outside
the curtain wall. FIG. 3 illustrates this mounting. Again, the
invention can be revised so there is only one support protrusion to
hold a third support plate and two protrusions from the side
opposite the flat side of the plate, but for safety's sake,
normally an upper set of three plates, and a lower set of three
plates would be used on each vertical H-beam, and a second upper
and lower set on an adjacent vertical H-beam. The bracket type of
support or deck bracket is mounted on the upper and lower set of
plates on each adjacent vertical H-beam, and restraints are placed
on the cylindrical protrusions to prevent the bracket type of
support from inadvertently coming off. With a deck plank placed on
the bracket type of support, a stable, mobile outrigger scaffold
with deck plank permits access to the exterior of a building to
conduct activities on the outside of the building such as
installing curtain wall, windows, painting and the like.
[0027] A further distinct advantage is obtained by the set of
plates from the first mode of the invention and two triads of
plates from the second mode of the invention. At the corner of a
building, using the corner vertical H-beam, and two adjacent
vertical H-beams (all three H-beams with the center section facing
the same way as in FIG. 2D), a first set of triad plates is mounted
on the adjacent vertical H-beam having a center section
perpendicular to the proposed curtain wall. The second triad is
mounted on the exterior two sides of the corner vertical H-beam,
and on the third side toward the just-referenced one of the two
adjacent vertical H-beams. With the first mode of invention mounted
on the remaining adjacent vertical H-beam having a center section
parallel to the proposed curtain wall, and lower identical set of
plate(s) placed on each vertical H-beam, and brackets set on the
cylindrical protrusions as shown in FIGS. 3 and 5, deck planks set
on the brackets enable access exterior to the building and around
the corner to conduct activities on the outside of the
building.
[0028] In addition, the invention is easily dissembled or assembled
by a single person, can be carried by a single person, and moved
around a floor, or from floor to floor as construction progresses.
Normally the setting of the deck plank would require two sets of
hands, but by sliding it onto one bracket, and then lifting the
opposite end onto an adjacent bracket, one person can set the deck
plank. Alternatively the deck plank can be slid onto an adjacent
bracket from an already mounted deck plank.
[0029] A third preferred mode of the invention uses the same
principles as the just-described mode, but proposes that the flat
plate that have ends shaped like L-folds on the shorter edges of
the plates, as opposed to the longer-edges, as in FIG. 8. A line
perpendicular to the longer edges will be oriented vertically. A
line perpendicular to the shorter edges of the plates will be
oriented horizontally and will be a horizontal axis. The plate may
be formed, cast or forged. This mode has the special utility of
being able to be mounted on vertical columns without an H-shape,
i.e., vertical columns that are square or rectangular. Another
modem construction method is to use square steel tubes and face
them with fireproofing. After the skeleton of a building has been
built, and the floor base structure is in place, and even after
fireproofing, the invention, by stripping a foot or so of the
(usually blown-on) fireproofing, can be mounted temporarily on a
vertical column. The pressures are such that the invention, once
mounted by the tightening of the clamping mechanism, mounted
through the L-fold, remains securely on the column and functions as
the first and second modes. The remaining plates of the invention
are mounted as before and the cylindrical and support protrusions
are mounted as in the earlier modes. Again, the clamping mechanism
can be a nut welded to a screw to grip with a wrench, which screw
passes through a nut welded or embedded in the L-fold through which
the screw passes and a mechanism with a rotationally flexible or
weaker end so the screw can put pressure on a clamp face applied to
the edge of a steel tube. With the plates of the invention as
before and the cylindrical and support protrusions as before, the
L-fold design referred to in this paragraph is equally useful
around the corner of a building built with square or rectangular
vertical steel tube columns.
[0030] A fourth preferred mode of the invention combines the
characteristics of the earlier modes. In this mode, a C-fold plate
is designed that a flat plate that has ends shaped like C-folds on
the shorter edges of the plates, as opposed to the longer edges, as
in FIGS. 1 and 9. A line perpendicular to the longer edges will be
oriented vertically. A line perpendicular to the shorter edges of
the plates, and parallel will be oriented horizontally and will be
a horizontal axis. The horizontal axis will run from what is
normally viewed as the front to the back of the vertical steel tube
structural column, and the front C-fold to the back C-fold of the
invention. The plate may be formed, cast or forged. A typical plate
would have shorter edges 6-8 inches long. A typical H-beam is 9
inches wide on the end face of a vertical H-beam.
[0031] This preferred mode of the invention uses the entire square
or rectangular vertical steel tube column standing on end as in
FIG. 9, either in steel tube form or as an H-beam, but more often
in vertical steel tube construction. The ends of the flat plate are
shaped like a C-fold which C-fold has an inside perimeter which can
fit around the face of the steel tube vertical column. The distance
between C-folds should be sufficient so that when one C-fold is
situated on one face of a vertical steel tube column, the other
C-fold with a clamping mechanism inside can be situated around the
opposite face of the vertical steel tube.
[0032] A further modification of this mode is to reinforce the top
and bottom of the C-fold on the end of the flat plate which has the
clamping mechanism. The reinforcement is by a metal plate which is
secured across the C-fold end of the flat plate, preferably on the
top and bottom. The reinforcement limits flexing of the 90 degree
angles in the C-fold. The flat plate is made long enough to
accommodate within the edges of the C-fold, the vertical column,
and the reinforcement metal plate. The clamping mechanism can be
retreated to be within the box formed by the reinforcement metal
plate, and the flat plate and the C-fold. The reinforcement can be
used on other modes of the invention to reinforce a square
"L-fold," or a C-fold.
[0033] Inside at least one of the C-folds is a clamping mechanism,
normally consisting of a metal piece to spread the pressure of a
clamping screw, which metal piece could have an indentation in it
and would be driven by a screw mounted through the selected C-fold.
The clamping mechanism can be a nut welded to a screw to grip with
a wrench, which screw passes through a nut welded or embedded in
the C-fold through which the screw passes. The clamping mechanism
includes a mechanism with a rotationally flexible or weaker end so
the screw can put pressure on a clamp face applied to the face of a
vertical steel tube column. A levered clamping mechanism could also
be employed to direct force against a column and pull the opposite
C-fold securely against the vertical steel tube analogous to the
apparatus as shown in FIGS. 1 and 5.
[0034] When the plate, is set facing on the vertical steel tube
column with the C-fold edges cupped around the end face of the
vertical steel tube column, the clamping mechanism is tightened,
and one C-fold is pulled more tightly into the beam while the
C-fold with the clamping mechanism grips the opposite side
resulting in a firmly mounted plate on the vertical steel tube
column.
[0035] In this latter fourth mode, mounted on the flat plate on the
horizontal axis are perpendicular cylindrical protrusions, normally
two. They support a bracket analogous to FIGS. 1 and 5.
Alternatively, or in addition, but not as a matter of requirement,
support cylindrical protrusions can be mounted on the C-folds (or
L-folds) in a position which is perpendicular to the flat side and
the horizontal axis and parallel to the folded face. A support
plate, designed like the earlier referenced third support plate
(also called a bracket plate), can be mounted on these horizontal
support cylindrical protrusions either as or also as a safety plate
to prevent the C-folds from spreading away from each other, or to
support a bracket on a second set of protrusions. The safety plate
is not required but furnishes at least a cosmetic security. In
steel tube construction, the invention with cylindrical tube
protrusions on the support plate or the flat plate with C-fold ends
defining a first horizontal plane, and with a second set of
cylindrical tube protrusions defining a second horizontal plane, is
particularly useful for rapid around-the-corner mounting of deck
planks. Note that with the design referenced in this paragraph for
the fourth mode, the orientation of the steel tube column is
immaterial as long as the C-folds will fit around one dimension of
the structural column.
[0036] In the fourth mode, as before, the cylindrical protrusions
may be smooth protrusions to facilitate a support bracket or deck
bracket being slid on the protrusions. Normally, a retaining pin on
the protrusion would prevent the support from sliding off.
Alternatively, the protrusion could be a bolt. Normally, a
retaining pin or a nut on the protrusion that is a bolt would
prevent the support from sliding off Ridges or notches could be
used to prevent the support from sliding off. Ridges or notches can
be used to prevent a deck plank or pic from sliding off the
bracket.
[0037] Again, on the cylindrical protrusions which are on a
horizontal axis, a horizontal bar with holes in it is mounted so
the horizontal bracket protrudes out from the plate mounted on the
vertical steel tube column. The horizontal bracket is then exterior
of a proposed outer curtain wall of a building. The bracket can
have a deck plank placed on it and functions as a walkable deck in
combination with another plate on the next H-beam over in a
building. Similarly, two plates, over and under, with one
protrusion could be used. However, for safety reasons, it is
preferable to use two plates on each vertical steel tube, each with
two perpendicular protrusions and use a bracket type of support on
each set of two plates on each of at least two vertical steel tube
columns. A bracket type of support could be an upper horizontal bar
with holes for the cylindrical protrusions on the interior end of
the upper horizontal bar with a lower angle bar with a horizontal
end having holes underneath the upper horizontal bar holes, with
the angle bar supporting the outside end of the upper horizontal
bar. This can also be referred to as a deck support. Further
bracing can be put on the bracket type of support. The horizontal
bar or the bracket type of support would normally have an upturned
end opposite the end with the holes to mount the bracket type of
support on the protrusions on the plate to prevent a deck plank
from inadvertently sliding off as seen in FIG. 5. Two sets of two
plates with bracket type of supports on adjacent vertical columns,
and a deck plank placed on them, and a restraint on the protrusions
provide a stable, mobile outrigger scaffold with deck plank which
permits access to the exterior of a building to conduct activities
on the outside of the building such as installing curtain wall,
windows, painting and the like as seen in side view of a mounted
bracket in FIG. 5.
[0038] Note that the support protrusions for the support plate are
therefore mounted parallel to the portion of the invention which is
the front vertical face of the C-fold perpendicular to the vertical
face of the flat plate which is bent to form the C-fold. The
support protrusions are at the end of the front vertical face
parallel to the horizontal axis. The support protrusions are thus
also parallel to the flat surface of the plate. When the plate
having the C-fold shaped ends is mounted on the vertical column,
normally the support protrusions run parallel to the proposed
curtain wall.
[0039] Particularly in the third and fourth modes and their
variations, by clamping the deck planks or pics to the support
brackets for the deck planks, the invention can be used on circular
columns. The clamping of the deck planks reduces any likelihood
that the deck support brackets on adjacent columns could move
toward or away from each other.
[0040] In each of the modes, the addition of an ear tab is
suggested, which is a metal hook on the clamping mechanism which
rides over the top edge of the flat plate. The tab is most easily
welded. The inventors prefer a tab on top and another on the bottom
of the clamping mechanism hooked under the bottom edge of the flat
plate. In the third and fourth mode, the inventors prefer a small
cut out in the metal reinforcement plate to accommodate the ear tab
which cut out is located away from the fold being reinforced in the
metal reinforcement plate adjacent to where it is attached to the
flat plate.
[0041] The horizontal brackets can be used to suspend ropes to hold
deck planks below them, or as suggested, motorized suspension
cables, or ropes for rappellers doing painting or window washing.
The invention may be used for supporting or establishing a deck
plank on bridge columns to assist in painting or maintenance. By
securing the deck plank to the bracket, the invention is functional
even on circular columns.
[0042] In yet another mode, for mounting on or suspension from an
overhang, or work from a horizontal structural member, or like
work, the invention is equally useful with some modification. The
plates as described may be used, but the cylindrical protrusions on
which a bracket is mounted must be turned 90 degrees, so the
bracket remains horizontal. Alternatively, the plates as described
may be used, but the bracket must have a mounting arm which is 90
degrees to the horizontal bracket. Another variation on this
alternative using the plates as described is to connect the top and
bottom of the mounting bracket, place apertures for mounting the
brackets on the now-vertical cylindrical protrusions, and thereby
enable the portion of the bracket supporting a deck plank to be
horizontal.
