Description

[Technical field]

[0001] This invention relates to a work gondola device. [Background technology]

[0002] Conventionally, repair work such as washing and painting in exterior wall construction on the exterior surfaces of buildings such as high-rise apartment buildings with balconies is carried out by workers riding in a work gondola that is suspended from above the building by a support wire and can be raised and lowered.

[0003] Such work gondolas are suspended from the roof by support wires, which causes the work gondola to swing away from the wall or to swing due to wind pressure, making work easier. There is also the problem that paints used during work may be scattered downward through the gap between the outer wall surface and the work gondola.

[0004] Therefore, as a method for preventing the above-mentioned swaying of the work gondola, a method is known in which a temporary guide rail is fixed to the outer wall surface of the balcony with mounting brackets, and a work gondola equipped with guide rollers is attached to this temporary guide rail, thereby preventing the work gondola from swaying while allowing the work gondola to move up and down along the outer wall surface (see Patent Document 1).

[0005] Moreover, in recent years, high-rise buildings such as super-high rise apartment buildings have been constructed, and as maintenance is also required for the exterior walls of these buildings, these temporary guide rails are temporarily installed from the top floor to the lower floors of the super-high rise apartment buildings to carry out repair work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] FIG. 1 is a perspective view showing a working gondola device 1 of the present invention installed on an outer wall surface 4 of a balcony 3 of a building 2 to be constructed, and FIG. 2 is an enlarged perspective view of the working gondola device 1.

[0017] As shown in Figure 1, this work gondola device 1 is installed so that when a work gondola 5 is used to perform work such as cleaning, repairing, painting, etc. on an exterior wall surface 4 on the balcony 3 side of an existing building 2 with a balcony, the work gondola 5 can swing left and right relative to the exterior wall surface 4 and cannot move away from it.

[0018] In the following explanation, as shown in Figure 1, the building side is referred to as the inside A, the opposite side is referred to as the outside B, the upper floor side of the building is referred to as the upper side C, and the lower floor side is referred to as the lower side D. The XX direction in Figure 1 is the left-right direction, the YY direction is the up-down direction, and the ZZ direction is the front-back direction.

[0019] This work gondola 5 is suspended by a lifting wire 6 hanging down from a lifting wire support 7 arranged on the roof of the building 2, and the work gondola 5 is mounted on the approximately vertical exterior wall surface 4 of the building 2 so that it can be raised and lowered in the vertical direction (YY direction) along the lifting wire 6.

[0020] By changing the installation position of the lifting wire support 7 on the roof 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.

[0021] In addition, as shown in Figures 1 and 2, a pair of tension rods 8 with an extendable function are fixed to the upper and middle sections of both sides of the work gondola 5, and the tip 8a of the tension rod 8 with a cushioning function abuts against the outer wall surface 4, preventing collision between the main body of the work gondola 5 and the outer wall surface 4, and the extendable function allows the distance between the work gondola 5 and the outer wall surface 4 to be set to any width.

[0022] The number of lifting wire support tools 7 and work gondolas 5 is not limited to one, but a plurality of them may be provided and raised and lowered simultaneously for construction.

[0023] Protective materials 9 are installed on the outer periphery of the work gondola 5, more specifically, on the left and right sides in the X-X direction of the work gondola 5, the back surface of the outer side B, and the upper surface of the upper side C, forming a protective space 9a inside the work gondola 5 and preventing paint, cleaning fluid, etc., generated from the work gondola 5 during construction from scattering outside the protective space 9a.

[0024] As shown in Figure 2, the work gondola device 1 of the present invention is arranged in pair on both left-right ends of the work gondola 5 on the exterior wall surface 4 on the balcony 3 side of a building 2, and the guide pole 10, which is arranged in the vertical direction of the building 2, is provided with an upper hanging portion 11 for attachment to the handrail portion 3a of the balcony 3 on one floor (hereinafter also referred to as the upper floor), a lower hanging portion 12 for attachment to the handrail portion 3a of the balcony 3 on another floor (hereinafter also referred to as the lower floor) located below the first floor, and a support portion 13 protruding from the guide pole 10 in the space below the bottom of the balcony 3 on the upper floor, and the guide pole 10 is detachably attached to the balcony 3 by the upper hanging portion 11 and the lower hanging portion 12.

[0025] Additionally, the upper hanging portion 11, the lower hanging portion 12 and the support portion 13 are arranged so that their respective mounting positions with respect to the guide pole 10 can be adjusted in the vertical direction (Y-Y direction) with the guide pole 10 as the axis.

[0026] FIG. 3 is a perspective view showing the guide pole 10, the upper hanging portion 11, the lower hanging portion 12 and the support portion 13. As shown in FIG.

[0027] As shown in Figure 3, the guide pole 10 has multiple pole through holes 10a opening at regular intervals on its side in the vertical direction (YY direction) of the guide pole 10, and the upper hanging portion 11 is disposed near the upper end of the guide pole 10, the lower hanging portion 12 is disposed near the lower end, and the support portion 13 is disposed near the center.

[0028] The upper hanging portion 11 has a vertical movement portion 15 which is formed in a cylindrical shape with openings at the top and bottom, and has multiple vertical movement portion holes 15d on its side which are spaced at the same intervals as the pole through holes 10a and open through the vertical movement portion 15.

[0029] The guide pole 10 is inserted inside the vertical moving section 15, and a fixing bolt 14 is inserted through the vertical moving section hole 15d and the pole through hole 10a and tightened with a nut (not shown), thereby fixing the vertical moving section 15 to the guide pole 10.By changing the insertion point of the fixing bolt 14 to any of the multiple pole through holes 10a, the upper hanging portion 11 can be positioned in the vertical direction (YY direction) of the guide pole 10.

[0030] An elastic portion 16 is provided on the building 2 side (inside A) of the upper hanging portion 11, and the elastic portion 16 is composed of a base piece 16a, an elastic body 16c, and an engagement piece 16b.

[0031] This base piece 16a is fixed to the side of the vertical movement section 15, and the end opposite the vertical movement section 15 is bent downward and hangs down inside the balcony 3.

[0032] Two elastic bodies 16c formed from metal springs are arranged side by side, one above the other, on the base piece 16a, and the elastic bodies 16c are interposed between the base piece 16a and the engagement piece 16b, and the base piece 16a, the elastic bodies 16c, and the engagement piece 16b are fixed together by welding or the like.

[0033] A space EE is formed between the engaging piece 16b and the vertical moving portion 15, and when the handrail portion 3a is inserted into this space EE, the engaging piece 16b moves inward A, clamping the handrail portion 3a of the balcony 3 while elastically compressing and engaging the handrail portion 3a of the balcony 3 toward the balcony 3 side (outside B).

[0034] In addition, a tapered surface 16d is formed at the lower end of the engagement piece 16b, which is curved and moves away from the handrail portion 3a of the balcony 3 as it moves downward.When the handrail portion 3a is inserted into the space EE, the upper surface angle of the handrail portion 3a abuts against the tapered surface 16d, guiding its insertion.

[0035] The lower hanging portion 12 disposed near the lower end of the guide pole 10 is constructed in the same manner as the upper hanging portion 11, and the same parts are given the same reference numerals and their description will be omitted.

[0036] Next, the support part 13 consists of a central vertical moving part 20 and a support piece 21, and the central vertical moving part 20 is formed in a cylindrical shape approximately similar to the vertical moving part 15, and a retaining pin 22 is installed so as to protrude in the axial direction through the central vertical moving part 20 and provide elastic biasing force.

[0037] Pin through holes 10b are opened at regular intervals near the center of the guide pole 10, and the support portion 13 is positioned in the vertical direction of the guide pole 10 by inserting the retaining pin 22 through these pin through holes 10b through the central vertical moving portion 20.

[0038] In addition, the support piece 21 is formed on the side of the central vertical moving section 20 with a predetermined length toward the building 2 side (inside A) within the worker movement space of the balcony 3, and a hanging portion 21a is provided at its tip.

[0039] As shown in Figure 2, the ends of a protective sheet 23 installed on the lower front of the work gondola 5 are hung on the hanging portions 21a of a pair of support portions 21 located on the left and right sides of the outer wall surface 4 on the balcony 3 side, and this protective sheet 23 covers the front of the work gondola 5, thereby preventing paint and the like from being scattered below the work gondola 5 and into the balcony 3 during painting and other construction work.

[0040] Further, a hook portion 25 is detachably attached to the guide pole 10, and this hook portion 25 is connected to a take-up wire 26a of a winch 26 mounted on the work gondola 5.

[0041] When the winch 26 is operated to wind up, the work gondola 5 is forced to be pulled toward the outer wall surface 4 (inner A direction), and by adjusting the amount of winding, the distance between the outer wall surface 4 and the work gondola 5 can be adjusted.

[0042] Next, a working method using the working gondola apparatus 1 will be described.

[0043] As shown in Figure 2, first, a worker boards a work gondola 5 and moves the work gondola 5 to the exterior wall surface 4 of the building 2 where construction work will be performed, and then installs a pair of work gondola devices 1 of this embodiment on the balcony 3 of the work floor.

[0044] First, the lower hanging portion 12 is fixed to the guide pole 10, and the upper hanging portion 11 is not fixed and is provided so as to be movable in the vertical direction (YY direction).

[0045] Next, as shown in Figure 4, the handrail portion 3a of the balcony 3 on the floor below the floor to be constructed is positioned within the space EE while being abutted against the tapered surface 16d of the lower hanging portion 12, and the handrail portion 3a is elastically compressed and engaged by the elastic portion 16.

[0046] Then, the vertical moving part 15 is slid on the guide pole 10 so that the upper hanging part 11 is positioned near the handrail part 3a of the balcony 3 on the upper floor, and the handrail part 3a of the upper floor is inserted into the space EE of the upper hanging part 11 while abutting it against the tapered surface 16d, and at that position the vertical moving part 15 is fixed to the guide pole 10 with the fixing bolt 14.

[0047] Next, as shown in FIG. 2, the hook portion 25 is attached to the guide pole 10 and the winch 26 is wound up, whereby the work gondola 5 moves toward the balcony 3 so that it is pulled by the guide pole 10 fixed to the balcony 3.

[0048] At this time, the tension rod 8 attached to the work gondola 5 abuts against the outer wall surface 4, and the work gondola 5 is prevented from swinging by being biased against the outer wall surface 4 with a constant tension, while maintaining the working space between the work gondola 5 and the outer wall surface 4 by the extension and contraction width of the tension rod 8.

[0049] Thereafter, the retaining pin 22 of the support part 13 is pulled out to release the lock, and the support part 13 is moved to near the bottom of the balcony 3 within the worker movement space of the balcony 3, and the retaining pin 22 is inserted through the pin through hole 10b to hold it in place.

[0050] When the end of the protective sheet 23 attached to the front of the work gondola 5 is hung on the hanging portion 21a, the protective sheet 23 spreads from below the front of the work gondola 5 into the space where workers move around on the balcony 3, preventing cleaning liquid and paint from splashing from the work gondola 5.

[0051] As described above, the work gondola device 1 of this embodiment is installed, and work such as cleaning and painting of the outer wall surface 4 of the balcony 3 is performed.

[0052] After the work on the first floor is completed, the worker removes the gondola anti-sway device 1 and moves it to the floor below to carry out work there.

[0053] When removing the guide pole 10, when the guide pole 10 is pulled upward, the elasticity of the elastic portion 16 causes the engagement piece 16b to move toward the base piece 16a (inner side A), and the upper hanging portion 11 and the lower hanging portion 12 are pulled out from above the handrail portion 3a.

[0054] Next, the work gondola device 1 is moved to the floor below where the work has been completed, and the guide pole 10 is attached to the handrail part 3a of the balcony 3 on the lower floor. However, since the dimensions of the upper hanging part 11 and the lower hanging part 12 on the upper and lower floors have already been adjusted, the upper hanging part 11 can be attached to the balcony 3 on the lower floor by the same process as described above, without changing the mounting position of the vertical moving part 15 of the upper hanging part 11 as described above.

[0055] With the above-mentioned configuration, according to the work gondola device 1 of the present invention, a simple and inexpensive work gondola device 1 can be provided by appropriately attaching short guide poles 10 to the outer wall surface 4 of the balcony 3 to be constructed, without installing a large number of temporary guide rails across all floors of a high-rise building.

[0056] Furthermore, since this device can be installed simply and precisely on the outer wall surface 4 of the balcony 3, construction can be carried out by setting a work surface of the minimum necessary size.

[0057] Furthermore, by providing an upper hanging portion 11 and a lower hanging portion 12 each having an elastic portion 16, the guide pole 10 can be detachably attached to the outer wall surface 4 on the balcony 3 side without using fastening tools such as screws, and the engaging piece 16b elastically engages the handrail portion 3a of the balcony 3, thereby holding the guide pole 10 against the outer wall surface 4 of the balcony 3.

[0058] In addition, since the guide pole 10 can be fixed to and released from the balcony 3 by the elastic pressure of the elastic portion 16, the work of moving it to another floor can be easily and quickly carried out by a single worker.

[0059] Furthermore, by providing the engaging piece 16b with a tapered surface 16d, the upper surface corner of the handrail portion 3a does not collide with the engaging piece 16b, and insertion can be performed smoothly. [Explanation of symbols]
