Modes for Carrying Out the Invention

[0015] The mode for carrying out the present invention will be described based on the examples shown in the drawings. [[ID=二十一]] [Example 1] FIG. 1 is a perspective view showing the state where the work gondola device 1 according to Example 1 is installed on the outer wall surface 4 of the veranda 3 in the building 2 under construction, and FIG. 2 is an enlarged perspective view of the work gondola device 1.

[0016] As shown in FIG. 1, when the work gondola 5 is used to perform operations such as cleaning, repairing, and painting on the outer wall surface 4 of the veranda 3 in the building 2 under construction, this work gondola device 1 is installed so that the work gondola's 5 swings in the left - right direction with respect to the outer wall surface 4 and does not separate from it.

[0017] Hereinafter, as shown in FIG. 1, the building side is defined as the inner side A, the opposite side as the outer side B, the upper floor side of the building as the upper side C, and the lower floor side as the lower side D. The X - X direction in FIG. 1 is the left - right direction, the Y - Y direction is the up - down direction, and the Z - Z direction is the front - back direction for explanation.

[0018] This work gondola 5 is supported by being suspended by a hoisting wire 6 hanging from a hoisting wire support 7 arranged on the rooftop of the building 2, and is installed so as to be able to move up and down in the up - down direction (Y - Y direction) on the substantially vertical outer wall surface 4 of the building 2.

[0019] By changing the installation position of the lifting wire support 7 on the rooftop in the left-right direction (XX direction), the suspension position of the work gondola 5, which is connected to and supported by the lifting wire 6 in a suspended state, can be moved in the left-right direction (XX direction) of the exterior wall surface 4.

[0020] Furthermore, the lifting wire support 7 and the work gondola 5 are not limited to one unit; it is also possible to install multiple units and raise and lower them simultaneously for construction work.

[0021] Protective members 9 are installed on the outer perimeter of the work gondola 5, specifically on the left and right sides in the X-X direction, the back of the outer side B, and the upper surface C of the upper side of the work gondola 5, forming a protective space 9a inside the work gondola 5, preventing paint, cleaning liquid, and other substances generated from the work gondola 5 during construction from scattering outside the protective space 9a.

[0022] As shown in Figure 2, the work gondola device 1 of the present invention is arranged in pairs at both ends in the left-right direction of the work gondola 5 on the outer wall surface 4 of the balcony 3 of the building 2, and consists of a guide pole 10 arranged in the vertical direction, an upper attachment part 11 that is attached to the handrail part 3a of the balcony 3 on the first floor (hereinafter also referred to as the upper floor), a lower attachment part 12 that is attached to the handrail part 3a of another balcony 3 located below the first floor (hereinafter also referred to as the lower floor), and a locking part 13 that locks from below to the bottom of the balcony 3 on the upper floor, and the guide pole 10 is detachably attached to the balcony 3 by these components.

[0023] The guide pole 10 is provided with an upper attachment portion 11, a lower attachment portion 12, and a locking portion 13, such that their respective mounting positions can be adjusted in the vertical direction (Y-Y direction) of the guide pole 10.

[0024] Furthermore, an upper attachment portion 11 is positioned near the upper end of the guide pole 10, and a lower attachment portion 12 is positioned near the lower end; these are formed from the same component.

[0025] Furthermore, retaining plates 10b are fixed to the upper and lower ends of the guide pole 10 to prevent the upper attachment portion 11, the lower attachment portion 12, and the locking portion 13 from falling off the guide pole 10.

[0026] Figure 3 is a perspective view showing the upper attachment portion 11 and the lower attachment portion 12.

[0027] As shown in Figure 3, the upper attachment section 11 is composed of a vertical movement section 15 and a horizontal movement section 16. The vertical movement section 15 can be positioned in the vertical direction (YY direction) around the guide pole 10, and the horizontal movement section 16 can be positioned in the front-back direction (Z-Z direction) around the vertical movement section 15.

[0028] The vertical movement section 15 consists of a cylindrical base 15a and a support shaft 15b fixed to the lateral surface of the base 15a, with the base 15a being slidable in the vertical direction relative to the guide pole 10.

[0029] Furthermore, the support shaft 15b extends in a direction perpendicular to the axis of the base portion 15a, and the length of the support shaft 15b is set to be longer than the thickness of the handrail portion 3a of the veranda 3.

[0030] A retaining piece 15c is fixed to the tip of the support shaft 15b, preventing the lateral movement part 16 from falling off the support shaft 15b.

[0031] Multiple through-holes 15d are provided on the side of the base 15a. Fixing bolts 14 are inserted through these through-holes 15d and the pole through-holes 10a of the guide pole 10 and tightened with nuts (not shown), thereby fixing the base 15a to the guide pole 10. The base 15a can also be positioned in the vertical direction (YY direction) of the guide pole 10 by changing its mounting position to any of the multiple pole through-holes 10a.

[0032] The lateral movement section 16 consists of a cylindrical engagement cylinder 16a and a restraining rod 16b extending from the lower side surface of the engagement cylinder 16a, and is installed on the support shaft 15b.

[0033] The engaging cylinder 16a is slidably mounted on the support shaft 15b in the left-right direction and is movable between the side surface of the base 15a and the retaining piece 15c, with the restraining rod 16b hanging down perpendicular to the axis of the engaging cylinder 16a.

[0034] Multiple through-holes 15e and 16c are provided on the side surfaces of the support shaft 15b and the engaging cylinder 16a. By inserting a fixing bolt 14 through the through-holes 15e and 16c and tightening it with a nut (not shown), the engaging cylinder 16a is fixed to the support shaft 15b and is also positioned in the front-to-back direction (ZZ direction) by changing its mounting position to any of the multiple through-holes 15e.

[0035] Furthermore, a locking part 13 is attached near the middle of the guide pole 10. Figure 4 is a perspective view showing the locking part 13 in a folded state, and Figure 5 is a perspective view showing it in an upright position and placed on the veranda 3.

[0036] As shown in Figure 4, the locking portion 13 consists of a cylindrical pivot shaft portion 20a that is slidably mounted on the guide pole 10, a foldable flap piece 20b connected thereto, an arm portion 20c that supports the upright position of the flap piece 20b, and a hook portion 21 that fits the arm portion 20c and is slidably mounted on the guide pole 10.

[0037] The pivot shaft portion 20a is provided with a pivot shaft hole 20d, and a shaft bolt 22 is pivotally supported by passing through the flap shaft hole 20e and the pivot shaft hole 20d provided at one end of the flap piece 20b, so that the flap piece 20b can pivot around the shaft bolt 22 as the axis of rotation, and can be displaced between an upright position which is horizontal and a folded position which is hanging down.

[0038] Furthermore, an arm support hole 20f is provided near the center of the flap piece 20b, and an arm shaft bolt 23 is passed through this arm support hole 20f and an arm shaft hole 20g provided at one end of the arm portion 20c to pivotally support the arm portion 20c with the arm shaft bolt 23 as the axis of rotation.

[0039] The other end of the arm portion 20c has a hook hole 20h formed therein, in which a part of the outer circumference is open. As shown in Figure 5, by swinging the flap piece 20b upward and fitting the hook hole 20h onto the retaining shaft 21a formed in the hooking portion 21, the flap piece 20b is supported by the arm portion 20c and stands upright. The flap piece 20b is positioned at the bottom of the veranda 3, thereby fixing the guide pole 10 to the veranda 3.

[0040] Furthermore, when the flap piece 20b is folded, the hook hole 20h is biased upward and released from the retaining shaft 21a, causing the flap piece 20b and the arm portion 20c to hang down under their own weight, and the guide pole 10 is released from being fixed to the veranda 3.

[0041] A bearing portion 20i is formed at the tip of the flap piece 20b, and a wire 24, which serves as a tensioning means, is provided between this bearing portion 20i and the bearing portion 20i of the pair of work gondola devices 1 provided at the other end of the work gondola 5 in the left-right direction.

[0042] A protective sheet 26 is installed between the wire 24 and the front of the work gondola 5, thereby blocking the area from the front of the work gondola 5 to the bottom of the upper floor balcony 3, and forming a means of suppressing the scattering of paint and other materials. Note that the tensioning means is not limited to the wire 24; a rod-shaped member or the like may be used between the bearing parts 20i, 20i.

[0043] Multiple through-holes 20j for the pivot shaft portion and 21b for the locking portion are provided on the side surfaces of the pivot shaft portion 20a and the locking portion 21. By inserting a fixing bolt 14 through the pole through-hole 10a and the pivot shaft portion through-hole 20j, and the pole through-hole 10a and the locking portion through-hole 21b, and tightening it with a nut (not shown), the locking portion 13 is fixed to the guide pole 10. Furthermore, by changing the fixing position to any of the multiple pole through-holes 10a, a positioning means in the vertical direction (YY direction) is configured.

[0044] Furthermore, as shown in Figure 2, a hook portion 25 is detachably attached to the guide pole 10, and this hook portion 25 is connected to the winding wire 4b of the winch 4a mounted on the work gondola 5.

[0045] When the winch 4a is wound up, the work gondola 5 is biased to be pulled toward the outer wall surface 4 (inward direction A), and the distance between the outer wall surface 4 and the work gondola 5 can be adjusted by adjusting the amount of winding.

[0046] Next, we will explain the work method using the work gondola device 1.

[0047] First, a worker boards the work gondola 5, moves the work gondola 5 to the exterior wall surface 4 of the building 2 where the construction work is to be carried out, and installs the work gondola device 1 of this embodiment on the balcony 3 of the work floor.

[0048] The installation procedure is not limited to this procedure, but in this embodiment, the upper attachment part 11 is first fixed to the guide pole 10, the locking part 13 and the lower attachment part 12 are not fixed and are made movable in the vertical direction (YY direction), and the flap piece 20b of the locking part 13 is folded.

[0049] At this time, since the retaining plates 10b are fixed to both the upper and lower ends of the guide pole 10, the locking portion 13 and the lower attachment portion 12 will not fall off the guide pole 10.

[0050] Next, the upper attachment part 11 is attached to the handrail part 3a of the balcony 3 on the floor where the installation is to be carried out, i.e., the upper floor. Then, the vertical movement part 15 of the lower attachment part 12, which is attached to the handrail part 3a of the balcony 3 on the lower floor, is slid upwards on the guide pole 10, causing the lower end of the restraining rod 16b to rise above the upper end of the handrail part 3a of the balcony 3 on the lower floor.

[0051] Then, the guide pole 10 is biased toward the inside A of the building 2, and the lateral movement portion 16 of the lower attachment portion 12 is positioned in the interior space of the lower floor balcony 3, while the vertical movement portion 15 is lowered until it contacts the upper end of the handrail portion 3a of the lower floor balcony 3, and at that contact position, the base portion 15a of the vertical movement portion 15 is fixed to the guide pole 10 with a fixing bolt 14.

[0052] Next, the lateral movement parts 16, 16 of the upper attachment part 11 and the lower attachment part 12 are moved outwards towards the outside B of the building 2, and the restraining rods 16b, 16b are slid to a position where they contact the inner walls of the upper and lower floor balconies 3. At that position, the engaging cylinders 16a, 16a are fixed to the support shafts 15b, 15b with fixing bolts 14, and the upper and lower floor balconies 3 are clamped between the guide pole 10 and the restraining rods 16b, 16b.

[0053] Then, the locking part 13 is raised to near the bottom surface of the upper floor balcony 3, the flap piece 20b is raised, the arm part 20c is hooked onto the retaining shaft 21a to raise the flap piece 20b, and while the flap piece 20b is in contact with the bottom surface of the upper floor balcony 3, the swing shaft part 20a and the locking part 21 are fixed to the guide pole 10 with fixing bolts 14 at that position.

[0054] As a result, the work gondola device 1 of the present invention is prevented from falling off the balcony 3 because the movement of the lower D and outer B sides is suppressed by the upper attachment part 11 and the lower attachment part 12 on the upper and lower balconies 3, and the movement toward the upper C side is also suppressed by the locking part 13.

[0055] In other words, the upper attachment portion 11 and the lower attachment portion 12 restrict the downward and outward movement of the guide pole 10, respectively, but do not restrict upward movement, and the locking portion 13 restricts the upward movement of the guide pole 10, but does not restrict downward movement. As a result, the guide pole 10 is fixed to the veranda 3.

[0056] Therefore, the work gondola device 1 can be attached to and detached from the handrail portion 3a of the veranda 3 and the bottom of the veranda 3 without using special fittings or the like to fasten and release it.

[0057] Furthermore, another work gondola device 1 is positioned opposite the work gondola 5 in the left-right direction, and by raising the flap piece 20b, the protective sheet 26 is erected in front of the work gondola 5 below, protecting the space extending from the work gondola 5 to the inside of the veranda 3.

[0058] Then, the hooking part 25 is attached to the guide pole 10, and the winding amount of the winch 4a is adjusted to adjust the distance between the work gondola 5 and the outer wall surface 4. The pulling of this winch 4a prevents the work gondola 5 from swinging or moving away from the outer wall surface 4.

[0059] Furthermore, when removing the guide pole 10 from the balcony 3, the flap piece 20b can be folded to release the fixing from below the balcony 3. When moving to the next work floor, since the mounting position adjustment of the guide pole 10 to the upper and lower balcony 3 has already been completed, the guide pole 10 can be raised and pulled out from the balcony 3 to the outside B, and the upper attachment part 11 and lower attachment part 12 can be simultaneously attached to the handrail part 3a of the balcony 3 on the next work floor, and then the locking part 13 can be raised and moved.

[0060] With the above configuration, the work gondola device 1 of the present invention provides a simple and inexpensive work gondola device for a work gondola 5 by appropriately attaching short guide poles 10 to the outer wall surface 4 of the balcony 3 where construction is to be carried out, without having to install a large number of temporary guide rails over all floors of a high-rise building.

[0061] Furthermore, since this device can be easily and precisely installed on the exterior wall surface 4 of the balcony 3, construction can be carried out by setting the minimum necessary work area.

[0062] Furthermore, since the guide pole 10 can be fixed to and released from the balcony 3 simply by swinging the flap piece 20b, the guide pole 10 can be moved to other floors easily and quickly.

[0063] Furthermore, since the protective sheet 26 is attached to the flap piece 20b of the locking part 13, the fixing of the guide pole 10 to the veranda 3 by the locking part 13 and the installation of the means for erecting the protective sheet 26 can be done simultaneously. As a result, one component can be used for both fixing to the veranda 3 and installing the protective sheet 26, simplifying the device.

[0064] Furthermore, since this protective sheet 26 is installed on the bottom surface of the upper floor balcony 3, it not only prevents paint from scattering from the work gondola 5 to the outside of the building 2, but also prevents it from scattering onto the inside and floor surface of the lower floor balcony 3.

[0065] Furthermore, since the hooking portion 25 connected to the winch 4a is attached to the guide pole 10, a biasing force is generated from the work gondola 5 to the guide pole 10, preventing the work gondola 5 from moving away from the outer wall surface 4 of the building 2 and from swinging from side to side. Moreover, even if the work gondola 5 accidentally rises or falls beyond the intended amount, the hooking portion 25 can be locked onto either the stopper plate 10b or the upper attachment portion 11 and locking portion 13 provided on the guide pole 10, preventing it from moving beyond its intended range.

[0066] Furthermore, even if the work gondola device 1 were to accidentally fall from the balcony 3 of the work floor, the hook portion 25 would not come off the guide pole 10 by engaging with the stopper plate 10b, the upper attachment portion 11, or the locking portion 13. The winch 4a connected to the hook portion 25 would then pull the work gondola device 1, preventing it from falling to the ground.

[0067] [Example 2] Figure 6 is a side view showing the locking portion 13 of the work gondola device 1 according to Embodiment 2 in a folded state, and Figure 7 is a side view showing the locking portion 13 in an upright state.

[0068] The locking portion 13 of Embodiment 2 divides the arm portion 20c of Embodiment 1 into an upper arm portion 27a and a lower arm portion 27b, connects the upper arm portion 27a and the lower arm portion 27b with a joint 28, and by bending the upper arm portion 27a and the lower arm portion 27b with this joint 27 as the axis of rotation, the flap piece 20b can be folded.

[0069] According to this embodiment, by pushing in the section 28 while lifting the flap piece 20b so that the upper arm portion 27a and the lower arm portion 27b become straight, the flap piece 20b can be supported in an upright position. Conversely, by pulling out the section 28, the flap piece 20b can be folded, and this operation can be easily performed. [Explanation of Symbols]
