Description

Technical Field

[0001] The present invention relates to a working gondola device.

Background Art

[0002] Conventionally, in repair work such as cleaning and painting in the exterior wall work of the outer wall surface of buildings such as high-rise condominiums having balconies, a working gondola suspended by a support wire from above the building is provided so as to be able to move up and down, and the work is performed by a worker boarding the working gondola.

[0003] Since such a working gondola is suspended and supported by a support wire from the rooftop, the working gondola sways away from the wall surface or sways due to wind pressure, resulting in poor workability. In addition, there is also a problem that paints and the like used during work scatter downward from the gap between the separated outer wall surface and the working gondola.

[0004] Therefore, as a method for preventing the sway of the working gondola as described above, a temporary guide rail is fixed to the outer wall surface of the balcony by a mounting bracket, and a working gondola equipped with a guide roller is provided on the temporary guide rail to prevent the sway of the working gondola while enabling the working gondola to move up and down along the outer wall surface (see Patent Document 1).

[0005] In recent years, high-rise buildings such as super high-rise condominiums have also been constructed, and since it is necessary to perform maintenance on the outer wall surfaces of these super high-rise buildings, this temporary guide rail is temporarily installed from the top floor to the lower floors of the super high-rise condominium to perform repair work.

[0016] As shown in FIG. 1, this working gondola device 1 is used when performing operations such as cleaning, repairing, and painting the outer wall surface 4 on the veranda 3 side of an existing building 2 having a veranda, using the working gondola 5. The working gondola 5 is installed so as to swing in the left - right direction with respect to the outer wall surface 4 and 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 working gondola 5 is suspended and supported by a hoisting wire 6 hanging from a hoisting wire support 7 arranged on the roof of the building 2. On the outer wall surface 4 configured in a substantially vertical shape of the building 2, the working gondola 5 is provided so as to be able to move up and down along the hoisting wire 6 in the up - down direction (Y - Y direction).

[0019] By changing the arrangement position of the hoisting wire support 7 on the roof in the left - right direction (X - X direction), the working gondola 5 coupled and supported by the hoisting wire 6 in the suspended state can have its suspension position moved in the left - right direction (X - X direction) of the outer wall surface 4.

[0020] Further, as shown in FIGS. 1 and 2, a pair of tension rods 8 having a telescopic function are fixedly provided at the upper and middle stages on both side surfaces of the working gondola 5, and the tip 8a of the tension rod 8 having a buffer function abuts against the outer wall surface 4, thereby preventing the collision between the main body of the working gondola 5 and the outer wall surface 4, and the distance between the working gondola 5 and the outer wall surface 4 can be set to an arbitrary width by the telescopic function.

[0021] Note that the lifting wire support 7 and the working gondola 5 are not limited to one, and a plurality of them can be arranged and lifted simultaneously for construction.

[0022] A curing member 9 is installed on the outer periphery of the working gondola 5, specifically, on the left and right surfaces in the X-X direction, the back surface of the outer side B, and the upper surface of the upper side C of the working gondola 5, and a curing space 9a is formed inside the working gondola 5 to prevent the paint, cleaning liquid, etc. from the working gondola 5 from scattering outside the curing space 9a during construction.

[0023] As shown in FIG. 2, the working gondola device 1 of the present invention is arranged in a pair at both ends in the left-right direction of the working gondola 5 on the outer wall surface 4 on the veranda 3 side of the building 2, and is attached to the guide pole 10 arranged in the vertical direction of the building 2, a wedge holding portion 11 attached to the handrail portion 3a of the veranda 3 on one floor (hereinafter also referred to as the upper floor), a hanging portion 12 attached to the handrail portion 3a of another veranda 3 (hereinafter also referred to as the lower floor) located below the one floor, and a support portion 13 protruding from the guide pole 10 is provided in the space below the bottom of the upper floor veranda 3, and the guide pole 10 is detachably attached to the veranda 3 by the wedge holding portion 11 and the hanging portion 12.

[0024] Further, the wedge holding portion 11, the hanging portion 12, and the support portion 13 are provided so that their respective attachment positions can be adjusted in the vertical direction (Y-Y direction) around the guide pole 10 with respect to the guide pole 10.

[0025] FIG. 3 is a perspective view showing the guide pole 10, the wedge holding portion 11, the wedge member 17, the hanging portion 12, and the support portion 13.

[0026] As shown in FIG. 3, in the guide pole 10, in the vertical direction (Y - Y direction) of the guide pole 10, a plurality of pole through - holes 10a are opened at regular intervals on its side surface. Near the upper end of the guide pole 10, the wedge holding portion 11 is provided, near the lower end, the hanging portion 12 is provided, and near the center, the support portion 13 is provided.

[0027] The wedge holding portion 11 has a vertical movement portion 15. The vertical movement portion 15 is formed in a cylindrical shape with openings at the top and bottom. On its side surface, a plurality of vertical movement portion holes 15a penetrate through the vertical movement portion 15 and open at the same intervals as the pole through - holes 10a.

[0028] The guide pole 10 is inserted inside the vertical movement portion 15. The fixing bolt 14 is inserted through the vertical movement portion hole 15a and the pole through - hole 10a, and tightened with a nut (not shown). Thus, the vertical movement portion 15 is fixed to the guide pole 10, and by changing the insertion position of the fixing bolt 14 in any of the plurality of provided pole through - holes 10a, the wedge holding portion 11 is provided so as to be positionable in the vertical direction (Y - Y direction) of the guide pole 10.

[0029] Further, on the wedge holding portion 11, a side plate 16 fixed to the side surface of the vertical movement portion 15 and a projecting piece 16a located opposite to the vertical movement portion 15 and protruding downward from the lower end of the end of the side plate 16 are formed.

[0030] The side plate 16 in the wedge holding portion 11 is placed on the upper surface of the handrail portion 3a, and the projecting piece 16a is provided so as to protrude downward from the upper surface of the handrail portion 3a of the veranda 3 inside the veranda 3 at A.

[0031] Also, between the projecting piece 16a and the vertical movement portion 15, in the front - rear direction (Z - Z direction) of the building 2, a space E - E longer than the thickness of the handrail portion 3a of the veranda 3 is formed, and the handrail portion 3a is inserted into this space E - E.

[0032] On the side of the tab 16a opposite to the vertical movement portion 15, a guide piece 16b is provided, and the guide piece 16b is formed to incline downward from above toward the inner wall surface side (outer side B) of the veranda 3.

[0033] Further, the wedge holding portion 11 is formed in an annular shape by the vertical movement portion 15, the side plates 16, and the guide piece 16b and has an internal space.

[0034] In the internal space of the wedge holding portion 11, a wedge member 17 can be inserted from above the internal space. The wedge member 17 has a thickness substantially equal to the inner dimension of the opposing side plates 16, 16, is shorter than the length of the side plate 16 in the front-rear direction (Z-Z direction), and has a tapered surface 17a having the same inclination angle as the guide piece 16b. The material is formed of wood.

[0035] With the above structure, when the handrail portion 3a of the veranda 3 is disposed between the vertical movement portion 15 and the tab 16a and the wedge member 17 is inserted into the internal space of the wedge holding portion 11 such that the tapered surface 17a is along the guide piece 16b, the distance between the vertical movement portion 15 and the wedge member 17 gradually approaches, and the handrail portion 3a of the veranda 3 is clamped by the wedge member 17.

[0036] Next, the hanging portion 12 has a lower vertical movement portion 18, and the lower vertical movement portion 18 is formed in substantially the same shape as the vertical movement portion 15. The length of the lower vertical movement portion 18 in the cylindrical vertical direction is set to be about twice as long as that of the vertical movement portion 15 and is provided so as to be positionable in the vertical direction (Y-Y direction) of the guide pole 10.

[0037] Further, a clamping piece 19 and a locking piece 19a are formed on the hanging portion 12.

[0038] The clamping piece 19 is formed in a substantially L shape such that a lower end portion 19b protrudes downward on the side opposite to the lower vertical movement portion 18. The handrail portion 3a can be inserted into the space F-F formed between the lower end portion 19b and the lower vertical movement portion 18, and the tip of the lower end portion 19b is set to be positioned below the upper surface of the handrail portion 3a.

[0039] On the side of the lower end portion 19b located on the veranda 3 side (outer side B), the locking piece 19a is formed with an inclined surface that separates from the handrail portion of the veranda 3 as it goes downward.

[0040] The interval of the space F-F is set to be narrower than the thickness of the handrail portion 3a of the veranda 3 toward the upper side and wider than the thickness of the handrail portion 3a toward the lower side. When the handrail portion 3a of the veranda 3 is inserted into the space F-F, the handrail portion 3a is locked to the inclined surface of the locking piece 19a at the position where the thickness of the handrail portion 3a matches the interval of the space F-F, and the handrail portion 3a is clamped by the hanging portion 12.

[0041] Next, the support portion 13 is composed of a central vertical movement portion 20 and a support piece 21. The central vertical movement portion 20 is formed in a substantially cylindrical shape similar to the vertical movement portion 15, and the holding pin 22 is installed so as to project axially through the central vertical movement portion 20 and have elasticity for biasing.

[0042] Near the center of the guide pole 10, pin through holes 10b are opened at regular intervals. The holding pin 22 is inserted through the central vertical movement portion 20 into the pin through holes 10b, whereby the support portion 13 is positioned in the vertical direction of the guide pole 10.

[0043] Also, the support piece 21 is formed on the side surface of the central vertical movement portion 20 to have a predetermined length toward the building 2 side (inner side A) within the operator movement space of the veranda 3, and a latching portion 21a is provided at its tip.

[0044] As shown in FIG. 2, at the latching portions 21a of the pair of support portions 21 located in the left-right direction on the outer wall surface 4 on the veranda 3 side, the ends of the curing sheet 23 installed on the lower front surface of the work gondola 5 are hung. By covering the front surface of the work gondola 5 with this curing sheet 3, it is possible to suppress the scattering of paint and the like below the work gondola 5 and into the veranda 3 during construction such as painting.

[0045] Further, a hook portion 25 is detachably attached to the guide pole 10, and this hook portion 25 is connected to a winding wire 26a of a winch 26 mounted on the work gondola 5.

[0046] When the work gondola 5 performs a winding operation of the winch 26, it is biased to be pulled toward the outer wall surface 4 side (inner side A direction), and by adjusting the winding amount, the distance between the outer wall surface 4 and the work gondola 5 can be adjusted.

[0047] Next, a working method using the work gondola device 1 will be described.

[0048] As shown in FIG. 2, first, an operator boards the work gondola 5, moves the work gondola 5 to the outer wall surface 4 of the building 2 where construction work is to be performed, and installs a pair of the work gondola devices 1 of this embodiment on the balcony 3 of the working floor.

[0049] First, the hanging portion 12 is fixed to the guide pole 10, and the wedge holding portion 11 is provided so as to be movable in the vertical direction (Y - Y direction) without being fixed.

[0050] Next, as shown in FIG. 4, the space F - F of the hanging portion 12 is positioned and locked to the handrail portion 3a of the balcony 3 on the lower floor of the floor to be constructed.

[0051] At this time, the space F - F is set such that the upper part is narrower than the thickness of the handrail portion 3a and the lower part is wider, so that the upper surface of the handrail portion 3a fits into the space F - F of the clamping piece 19.

[0052] Then, the vertical movement portion 15 is slid on the guide pole 10 so that the wedge holding portion 11 is positioned near the handrail portion 3a of the upper - floor balcony 3, the side plate 16 of the wedge holding portion 11 is placed on the upper surface of the handrail portion 3a of the upper floor, and the vertical movement portion 15 is fixed to the guide pole 10 with the fixing bolt 14 at that position.

[0053] Next, as shown in Fig. 5, when the wedge member 17 is inserted into the internal space of the wedge holding portion 11 from above, the wedge member 17 moves along the guide piece 16b toward the handrail portion 3a side, and the handrail portion 3a is clamped by the wedge member 17 and is attached while being firmly fixed.

[0054] Next, as shown in Fig. 2, when the engaging portion 25 is attached to the guide pole 10 and the winch 26 is wound, the work gondola 5 moves toward the veranda 3 side (inner side A) so as to be pulled toward the guide pole 10 fixed to the veranda 3.

[0055] At this time, when the strut bar 8 attached to the work gondola 5 abuts against the outer wall surface 4, the work gondola 5 is held in a state where it has a certain tension while maintaining the working space between the work gondola 5 and the outer wall surface 4 by the expansion and contraction width of the strut bar 8, and is prevented from swinging while being biased against the outer wall surface 4.

[0056] Thereafter, the holding pin 22 of the support portion 13 is pulled out to release the lock, the support portion 13 is moved to the vicinity of the bottom of the veranda 3 within the workman movement space of the veranda 3, and the holding pin 22 is inserted into and held by the pin through-hole 10b.

[0057] Then, when the end of the curing sheet 23 attached to the front surface of the work gondola 5 is hung on the hanging portion 21a, the curing sheet 23 spreads from below the front surface of the work gondola 5 into the workman movement space of the veranda 3, preventing the scattering of the cleaning liquid and paint from the work gondola 5.

[0058] As described above, the work gondola device 1 of this embodiment is installed, and operations such as cleaning and painting of the outer wall surface 4 of the veranda 3 are performed.

[0059] After the work on the first floor is completed, the operator removes the working gondola device 1 and moves it to the lower floor for work. When removing the guide pole 10, the operator removes the wedge member 17 from the wedge holding portion 11, and further pulls up the guide pole 10 upward, so that the wedge holding portion 11 and the hanging portion 12 are disengaged from the handrail portions 3a on the upper and lower floors. Then, the working gondola device 1 is directly moved to the lower floor and mounted on the balcony 3 on the lower floor by the same process as described above.

[0060] At this time, even if the guide pole 10 accidentally falls off the balcony 3, the guide pole 10 is suspended by the catching portion 25, so that the fall of the guide pole 10 to the ground is suppressed.

[0061] With the above configuration, according to the working gondola device 1 of the present invention, without installing a large number of temporary guide rails across all floors of a high-rise building, the short guide pole 10 is appropriately attached to the outer wall surface 4 of the balcony 3 where construction is to be carried out, so that a simple and inexpensive working gondola device 1 can be provided.

[0062] In addition, since this device can be installed simply and precisely on the outer wall surface 4 of the balcony 3, a working surface within the minimum necessary range can be set for construction.

[0063] Furthermore, by providing the wedge member 17 in the wedge holding portion 11, the tightening amount with respect to the handrail portion 3a can be adjusted without using tools such as, and it can be firmly fixed.

[0064] Also, by setting the space F - F of the hanging portion 12 such that the upper part is narrower than the thickness of the handrail portion 3a and the lower part is wider, the tightening strength can be adjusted by the insertion width, and the hanging portion 12 located on the lower floor can be easily fitted into the handrail portion 3a even when the guide pole 10 is operated from the upper floor.

[0065] Therefore, due to the configuration of inserting the wedge member 17 into the wedge holding portion 11 and locking the clamping piece 19 of the hanging portion 12, the guide pole 10 can be detachably attached to the outer wall surface 4 of the veranda 3, making it easy to fix and release the veranda 3. Thus, an operator can perform this operation alone from an upper floor.

[0066] That is, if the wedge holding portion 11 is provided on both the upper and lower floors, it is necessary to remove the wedge member 17 on both the upper and lower floors, and substantially, two operators are required to perform the operation. Also, if the hanging portion 12 is provided on both the upper and lower floors, since the clamping piece 19 locks and clamps from above the handrail portion 3a, the guide pole 10 is likely to fall off when an upward force is applied to it.

[0067] According to this embodiment, the above matters can be solved, and a gondola device 1 for work can be configured with workability that enables an operator to easily and quickly transfer it to another floor alone.

[0068] Also, during the installation process of the wedge holding portion 11 on the handrail portion 3a of the veranda 3, even if the guide pole 10 unexpectedly swings and the wedge holding portion 11 is about to be pulled out from the handrail portion 3a, the protruding piece 16a of the wedge holding portion 11 is hooked on the handrail portion 3a, restricting the guide pole 10 from falling outside the building 2.

[0069] In this embodiment, the wedge holding portion 11 is on the upper floor and the hanging portion 12 is on the lower floor. However, the same effect can be achieved even if the wedge holding portion 11 is on the lower floor and the hanging portion 12 is on the upper floor.
