Description
TECHNICAL FIELD
[0001] The present invention relates to a construction climbing
system with improved structural stability and, more specifically,
to a construction climbing system with improved structural
stability, and having improved form, the system being capable of
more stably operating the attachment and detachment of a gang form
provided in the climbing system without shaking, enabling the
vertical movement of the climbing system to be smooth without
stopping so as to ensure structural stability, and enabling a
working space of an operator to be ensured as wide as possible by
using an auxiliary extension platform, thereby enabling work
stability of the operator to be improved.
BACKGROUND ART
[0002] In general, in order to build a reinforced concrete
building, a framework of the building is constructed by arranging
reinforcing bars to form a frame of the building, installing a
plurality of formwork on outsides of the frame, pouring concrete,
and then curing the concrete for a specified period.
[0003] Such a formwork composed of a plurality of wood panels is
not only time-consuming to manufacture, but is also impossible to
reuse because most of the formwork is broken in the process of
removing the formwork after curing the concrete. Also, it is
impossible for a scaffold, separately installed for
building-exterior work and reinforcing-bar work, to be recycled
once the use of the scaffold is finished.
[0004] Therefore, in recent years, large formwork called gang form
cages, which are installed outside of buildings during concrete
pouring, have been developed and necessarily used in constructing
high-rise buildings. The gang form cage is made of a gang form
providing a concrete pouring surface and a working platform
connected to the gang form to provide a workspace.
[0005] The gang form cage is set to be temporarily fixed by
bolt-fastening, to outer wall surfaces corresponding to each floor
while being moved to a specified height by a tower crane so that
the outer wall of the upper floor is lifted in consecutive order
and constructed starting from the lower floor of the concrete
structure.
[0006] Meanwhile, in recent years, efforts have been made to
eliminate the work load of the tower crane by providing a cylinder
for lifting the cage integrally equipped with the cage on one side
of the gang form cage.
[0007] As an exemplary embodiment of the gang form cage as
described above, there is a construction climbing system with a
climbing shoe or a guide shoe, which was registered with Korean
patent No. 10-1152963 (Registration Date: May 29, 2012).
[0008] This construction climbing system includes: at least one
climbing bracket 12 for supporting a formwork; at least one
climbing profile 14 disposed in the climbing direction with respect
to the building; and at least one climbing shoe or guide shoe 10
which may be installed in a building or the climbing bracket 12,
and interacts with the climbing profile 14 for a climbing
operation.
[0009] The climbing shoe or guide shoe 10 is characterized as
having at least one brake 18 acting on the climbing profile 14, and
in that the brake is coupled at all times to the climbing profile
by receiving transferred pretension for the climbing profile
14.
[0010] In another embodiment, the climbing system with Utility
Model Registration No. 20-0445741 (Registration Date: Aug. 20,
2009) is characterized as including
[0011] a shoe 200 attached to the building wall 100;
[0012] a rail 300 connected to the shoe 200 and provided with a
plurality of locking protrusions 320;
[0013] a cylinder 500 coupled to the shoe 200;
[0014] a support member 600 connected to a hinge shaft 630 on the
top of the cylinder 500,
[0015] whereby a rotation limiting groove 675 is provided adjacent
to the hinge shaft 630 and a support member 600 is provided with a
protrusion 640 located in the rotation limiting groove 675,
[0016] and the support member 600, which is moved downward as the
cylinder 500 is reduced, is pivoted about the hinge shaft 630 when
colliding with the locking protrusion 320.
[0017] However, in the conventional gang form cage as described
above, connecting bolts protrude to both sides in the process of
connecting a plurality of rails connected to the shoe attached to
the building. Accordingly, in the process of lifting the gang form
cage upward through a lifting device, the connection bolts
protruding from the shoe are easily caught, and thus lifting work
may not be performed smoothly.
[0018] In addition, in the case of the gang form installed in the
cage, demolding work is not easily performed in the process of the
demolding after pouring and curing the concrete. Accordingly, as
the workers perform the demolding work in narrow cages, the
demolding process is very difficult and dangerous, and thus the
work stability of the workers is not guaranteed.
[0019] Also, in an effort to ensure the work stability of the
worker as described above, an auxiliary scaffold is installed in
the front part of a working scaffold installed in the cage and
tries to improve work stability by expanding the working range of
the worker. However, since the auxiliary scaffold to be installed
does not have strong support due to connecting to the existing
working platform by hooking or bundling with wire, there is a
problem that a severe industrial accident such as falling of a
worker may occur when the connection state of the wire is poor.
DISCLOSURE

plurality of climbing rails installed on one side of the building
climbing system. Accordingly, the movement process of the guidance
rail connected to the shoe may be made stable by minimizing jamming
in the process of moving, and also the forward and backward
movement of the gang form installed in the climbing system may be
made stable. Therefore, the demolding work of the gang form may be
safely performed, and the worker may secure the maximum working
space for demolding and installing the gang form, thereby providing

protruding upward in the middle of the fixed base; and
[0028] a moving base 230 rotatably connected to the fixed base 220,
wherein a first connection part 234 is rotatably assembled with a
lower part of a moving frame 240 on one side of a plurality of
fixed plates 233 with an insertion groove 232 at an outer side of

moving base and rotatably assembled inside the pair of C-shaped
steel beams 231, and a locking protrusion 237 protrudes from
outside of the pair of C-shaped steel beam 231.
[0029] Accordingly, the object of the present invention may be
achieved by the construction climbing system with improved
structural stability.
[0030] The construction climbing system may further include an
auxiliary scaffold 24 connected to one side of the working scaffold
20 by an extension bracket 23 and including an auxiliary support
bar 241 and an auxiliary perforated scaffold 242, wherein
[0031] the extension bracket 23 is integrally provided with a first
fitting groove 261 in which the frame 10 is fitted at a lower part
of the extension bracket, a second fitting groove 262 in which a
support bar 21 of the working scaffold 20 and the auxiliary support
bar 241 of the auxiliary scaffold 24 are fitted in an upper part of

Advantageous Effects
[0037] As described above, the construction climbing system with
improved structural stability according to the present invention
minimizes the protruding part for connecting the climbing rails.
The structural stability is achieved by improving the assembly
structure of the climbing rails installed to have a similar length
to the cage by connecting a plurality of climbing rails. Therefore,
there is an effect that the construction climbing system moving in
a vertical direction may move in a more stable state. The effect is
achieved by preventing the cage movement from being obstructed due
to the protruding part being caught by the shoe during the vertical
movement of the cage.
[0038] In addition, the gang form is connected to the upper part of
the cage in a structure capable of reversing, in other words, the
lower surface of the gang form frame is contacted with upper
surface of the cage frame with each other, so that the gang form
has a structure to be moved back and forth by the gear coupling of
the rack and the pinion. Accordingly, there is an effect that the
gang form may be removed or installed in a state where left and
right balances are maintained without biasing to one side, so that
the gang form may be removed and moved stably.
[0039] In addition, when the worker is demolding and installing the
gang form or working in the cage, an auxiliary scaffold that may be
installed in close proximity to the position of the building on one
side of a working scaffold is provided, and an improved bracket is
also provided so that the installation state of the auxiliary
scaffold may be firmly maintained. As a result, the work
environment of the worker may be safely secured by providing the
working radius for the worker as wide as possible, thereby
preventing accidents such as falling of a worker or s working tool
that may occur during the work.

according to the present invention.
[0056] As shown in the drawings, the construction climbing system
with improved structural stability according to the present
invention (hereinafter, referred to as a "climbing system") 1
largely includes a cage 100 provided in a structure or a building
so as to be movable in the vertical movement, and a gang form 200
installed in a structure capable of moving forward and backward on
the top of the cage 100.
[0057] The cage 100 has a frame 10 designed to have a height
corresponding to one or two or more floors of a structure or
building to be constructed, and a predetermined width and depth; a
plurality of working scaffolds 20 installed inside the frame 10; a
shoe 300 installed at one side of the frame to be installed in a
building; and a climbing rail 30 assembled in a sliding-movable
form.
[0058] The frame 10 is made as a unit of a predetermined standard
to form an overall outer shape of the cage 100 of the present
invention. That is, the frame may be assembled into a grid-like
form by using a conventional steel frame, for example, a square
pipe, including channel-shaped steel beam or H-shaped steel beam
and the like.
[0059] In addition, the size of the frame 10 may be manufactured in
an appropriate size in consideration of various site conditions,
such as the size of the building to be constructed. In the case of
a general building, it is proper that the width may be about 6 m to
15 m, and in the case of height, the height may be to cover about 2
to 4 floors, and the depth may be about 0.6 to 1.2 m.
[0060] In addition, the guidance rail 30 is assembled to one side
of the frame 10 and a protective screen (not shown) such as a PE
net, a wire mesh, or a tent is attached to the other side of the
frame 10 to prevent falling the workers or falling objects, or to
prevent dust or foreign substances generated during operation from
flying into the air.
[0061] In addition, although the frame is shown to cover the height
of the two floors of the building in the illustrated embodiment, a
specific size may be adjusted in discretion according to conditions
of a construction site. In addition, although not shown, it may be
sufficiently considered for the frame 10 provided in a lattice
shape to be structurally reinforced by a turn buckle or bracing as
necessary.
[0062] The working scaffold 20 is to provide a space in which the
worker working inside the cage 100 may safely work, and is
assembled to the frame 10 as shown in FIGS. 7 to 9. Also, the
working scaffold includes: a plurality of support bars 21 made of
the same pipe or channel section steel, the same as the frame 10; a
perforated scaffold 27 assembled to the upper part of the support
bar 21; and an extension bracket 23 to which the auxiliary scaffold
24 is assembled to one side thereof and coupled to the frame 10 and
the support bar 21.
[0063] The perforated scaffold 27 provides a protruding hole 271
protruding from the edge of the hole (not shown) to the upper part
to prevent the worker from slipping during the work on the
perforated scaffold.
[0064] The extension bracket 23 are integrally provided with a
first fitting groove 261 to which the frame 10 is fitted at the
bottom thereof and a second fitting groove 262 to which an
auxiliary support bar 241 of the auxiliary scaffold 24 and the
support bar 21 of the working scaffold 20 is fitted at the top
thereof, and a plurality of fastening holes 263. Accordingly, the
support bar 21 and the auxiliary support bar 241 are bolted to the
second fitting groove 262 in a state in which the frame 10 is
fitted into the first fitting groove 261 to be firmly fixed with a
bolt (not shown). Therefore, the auxiliary scaffold 24 is connected
to the frame 10 and the working scaffold 20 to maintain a firmly
provided state.
[0065] In addition, the auxiliary scaffold 24 includes the
auxiliary support bar 241 in which one side thereof is fastened to
the second fitting groove 262 of the extension bracket 23 and an
auxiliary perforated scaffold 242 assembled on the upper part of
the auxiliary support bar 241.
[0066] Particularly, as an inclined surface 243 is provided at the
end connected to the extension bracket 23 of the auxiliary support
bar 241, the auxiliary scaffold 24 is rotatably provided without
being caught upward in a state assembled to the extension bracket
23. Accordingly, when not being in use, the auxiliary scaffold 24
may be eliminated by removing it from the extension bracket 23 or
by removing only a part of the fastening bolt and rotating the
upper part to prevent the cage 100 in motion from being caught by
the auxiliary scaffold 24.
[0067] Before being assembled and provided on one side of the frame
10, the climbing rail 30 is provided in such a manner that the
climbing rail 30 has the same or similar height as that of the
frame 10 by connecting a plurality of climbing rails to each other,
like a prefabricated frame 10.
[0068] That is, the climbing rail 30 integrally provides a locking
rack 32 having a wedge-shaped tooth inclined to one side between a
pair of C-shaped steel beam 31 as shown in FIG. 2.
[0069] At this time, the locking rack 32 coupled between the
C-shaped steel beam 31 protrudes from the end part thereof to the
lower part of the C-shaped steel beam 31 to form a protrusion 322
having a connection hole 321. Also, the climbing rail provides a
housing groove 312 having connection holes 311 at both sides with
the same depth as the length of the protrusion 322 on the upper
part thereof to connect to the protrusion 322 of the locking gear
32. Accordingly, the protrusion 322 is inserted into the housing
groove 312' of the climbing rail 30' so that each of the connection
holes 311' and 321 is located in the same line, and then climbing
rail 30 and 30' are firmly connected to each other by being
fastened with a fastening member 33.
[0070] In addition, since the fastening member 33 minimizes the
part protruding to the outside while maintaining a firm connection
state in connecting the plurality of climbing rails 30, the
climbing rail 30 is not blocked in movement by minimizing jamming
with the shoe 300 when the shoe 300 is in close contact with the
outer surface of the climbing rail 30 afterward.
[0071] That is, the fastening member 33 penetrates the respective
connection holes 311' and 321, and includes a female coupler 331
composed of a female screw hole 3311 and a convex lens-shaped
female screw head 3312, and a male coupler 332 composed of a male
screw body 3321 screwed into the female screw hole 3311 and a
convex lens-shaped male screw head 3322. The fastening member 33 is
to screw the male screw body 3321 of the male coupler 332 to the
female screw hole 3311 in a state that the female coupler 331 is
inserted into the connection hole 311 and 321 so as to expose the
screw heads 3312 and 3322 of the male coupler 332 and the female
coupler 331 to the outside of the connection hole 311'.
Accordingly, when the climbing rail 30 moves while being connected
to the shoe 300, only the convex-type screw heads 3312 and 3322 are
exposed in minimum to ensure stable movement of the climbing rail
without shaking due to the locking. Accordingly, when the climbing
rail 30 is connected to the shoe 300 only the convex lens-shaped
screw heads 3312 and 3322 are at least exposed, thereby ensuring
stable movement of the climbing rail without shaking due to the
locking.
[0072] Meanwhile, the gang form 200 is provided in a form that is
movable forward and backward in the upper part of the cage 100, and
includes: a base 210 assembled in a slidable form with the frame 10
in the lower part thereof; a moving frame 240 assembled with the
frame 10 in a vertical direction; and an inclined support strut 250
which maintains the fastening state between the base 210 and the
moving frame 240.
[0073] The base 210 is composed of a fixed base 220 fixed to the
cage 100 and a moving base 230 assembled to be slidably movable
with the fixed base 220. Since the moving frame 240 in which the
formwork is installed on one side of the moving base 230 is
assembled with the fixed base 220 by the inclined support strut 250
and installed in a form in which the inclination is adjustable, the
base 210 ensures that the wall surface is being built in a state
exactly perpendicular to the floor surface.
[0074] The fixed base 220 has a pair of C-shaped steel beam 224
facing to each other, and includes: a protruding part 221
positioned on one side thereof, and which may be caught by the
shoe; a spacing plate 222 on the other side thereof; a part of the
rack gear 223 protruding upwards in the middle thereof.
[0075] The moving base 230 is fixedly spaced apart at regular
intervals by a method such as welding a plurality of fixed plates
233 having an insertion groove 232 in the lower part in a state in
which the pair of C-shaped steel beam 231 is faced to each other.
Also, the moving base may include: a first connection part 234
rotatably assembled with a lower part of the moving frame 240 on
one side thereof; and a second connection part 235 rotatably
assembled with the inclined support strut 250 on the other side
thereof; and a gear 236 meshed with the rack gear 223 at a central
part thereof, and rotatably assembled inside the pair of C-shaped
steel beams 231, and a locking protrusion 237 protrudes outside the
pair of C-shaped steel beam 231.
[0076] The fixed base 220 and the moving base 230 configured as
described above are inserted into the insertion groove 232 of the
moving base 230 by the upper part of the fixed base 220, so that
the gear 236 of the moving base 230 is meshed with the rack gear
223 of the fixed base 220. At the same time, the lower surface of
the C-shaped steel beam 231 of the moving base 230 is in close
contact with the upper surface of the C-shaped steel beam 224 of
the fixed base 220. Accordingly, in a state in which the moving
base 230 is in surface contact with the upper surface of the fixed
base 220 and stably supported, a wrench (not shown) is connected to
the locking protrusion 237 protruding to both sides of the gear
236. Also, by manually rotating the gear 236, the moving base 230
is moved back and forth from the fixed base 220.
[0077] Moreover, the rotation of the gear 236 may be driven
manually through a wrench (not shown) as described above, and in
another embodiment, the gear 236 may be automatically controlled
through a connection with a drive motor (not shown).
[0078] Also, the gang form 200 is fastened due to a protruding part
221 protruding on one side of the fixed base 220 by being caught by
the shoe 300 installed on the building, thereby preventing workers
from falling and ensuring the stable driving of the gang form
200.
MODE FOR INVENTION
[0079] Meanwhile, FIG. 10 is a view of a modified aspect of the
construction climbing system with improved structural stability
according to the present invention. In this embodiment, the
finishing cage 400 having an extended working scaffold 410 for the
finishing work of the building is integrally provided at the lower
part of the cage 100. Accordingly, since it is not necessary to
provide a separate temporary facility for external work of a
building, the overall construction period of the building may be
shortened, thereby reducing the temporary construction cost and
construction period.
[0080] Meanwhile, FIG. 11 is a view showing a modified embodiment
of the cage of the construction climbing system with improved
structural stability according to the present invention. In the
present embodiment, a configuration of the gang form among
configurations of the climbing system is removed, and the climbing
system is reconfigured with only the cage to perform an external
finishing work of the structure.
[0081] In addition, FIG. 12 shows a modified mode of the cage shown
in FIG. 11. As shown the above, an auxiliary cage 400 is provided
to slidably move to both sides in the cage so as to expand the
workspace to a wider form, thereby securing an exterior working
space more efficient.
[0082] Although the present invention has been described in
association with the above-mentioned preferred embodiments, it will
be readily apparent to those skilled in the art that various
modifications and variations may be made without departing from the
spirit and scope of the invention, it is obvious that all such
modifications and variations belong to the scope of the claims
being attached.
INDUSTRIAL AVAILABILITY
[0083] As described above, the climbing system 1 according to the
present invention includes the cage 100 built by utilizing the
frame 10 designed to have a height corresponding to one or more
floors, and to have a predetermined width and depth. Thus, the
problem of load during maintenance and lifting may be improved due
to light weight of the cage. Also, the climbing system 1 according
to the present invention provides a stable working environment due
to the expansion of the working space through a configuration of an
auxiliary scaffold provided to the front side of the working
scaffold. At the same time, by fastening the auxiliary scaffold
using a separate bracket, a stable installation state may be
maintained. In particular, the climbing system 1 according to the
present invention minimizes the protrusion due to the assembly of
the climbing rail installed in front of the cage 100 so as to make
the vertical movement more smoothly and stably in connection with
the shoe, thereby improving the stability of the work environment
and the risk of falling.
[0084] In addition, in the case of the gang form installed in the
upper cage, the moving base is connected to the fixed base firmly
installed to the cage, in a form capable of moving forward and
backward. In this case, by moving fixed base and moving base whose
surfaces are contacted with each other, the bias of shifting to one
side is prevented and the weight of the moving base is not
transmitted to the meshing of the gear, thereby ensuring a stable
movement of the gang form.
