=== Embodiment ===
In the present embodiment, in the interior space of the elevator shaft, asbestos (corresponding to deposits) already sprayed as a fireproof coating on a steel beam or the like is removed or rendered harmless. In the following description, the direction in which the elevator car moves up and down in the elevator shaft is referred to as the vertical direction (vertical direction). In addition, a direction along a wall surface provided with an opening for getting on and off the elevator car is referred to as a left-right direction (horizontal direction), and a direction that is a depth direction with respect to the elevator car is referred to as a front-rear direction (horizontal direction).

<< Elevator configuration >>
FIG. 1 is a side sectional view of an elevator EV provided with a work scaffold 30 according to the present embodiment.

  As shown in FIG. 1, the elevator EV includes an elevator shaft EVS partitioned into a part of a building such as a building, and an elevator car 10 that is guided so as to be vertically movable up and down along the vertical direction in the elevator shaft EVS. A hoisting machine 19 that is disposed in a machine room MR above the elevator shaft EVS and lifts the elevator car 10 up and down using a suspension rope R provided with a counterweight (hereinafter referred to as a counterweight) W. And. In addition, a work platform 30 is provided at the upper part of the elevator car 10. Details of the work scaffold 30 will be described later.

  The elevator shaft EVS is a rectangular parallelepiped space that is long in the vertical direction. In this elevator shaft EVS, a steel beam (not shown) and a steel column (not shown) are assembled in a substantially rectangular parallelepiped shape that is long in the vertical direction, and a column beam frame is constructed. Further, a concrete panel such as an ALC (bubble concrete) plate is disposed between the steel beams adjacent in the vertical direction, whereby the side wall 23 of the elevator shaft EVS is formed so as to surround the front, rear, left and right sides. Moreover, the ceiling part 26 is formed in the upper end of the elevator shaft EVS, and the floor part 28 is formed in the lower end. Thereby, the inside of the elevator shaft EVS is a substantially closed space in which all of the six directions of up, down, front, back, left and right are closed.

  The front side wall 23 of the four side walls 23 is formed with an entrance (not shown) for the elevator EV corresponding to each floor of the building, and slides to the left and right at the opening. An opening / closing door 24 is provided. In the present embodiment, the floors of the nth floor (n> 2) and the (n-1) th floor are atriums, and the elevator car 10 does not stop on the nth floor. That is, the uppermost stop floor of the elevator car 10 is the (n-1) floor, and the open / close door 24 is provided up to the (n-1) floor.

  By the way, in general, the steel beam of the column beam frame or the steel frame of the steel column may be partially exposed in the elevator shaft EVS. And for such steel exposed parts, fireproof coating is indispensable under the Building Standards Act, and asbestos has been used as the material before. Therefore, asbestos may still be exposed in the existing elevator shaft EVS.

  For such asbestos, for example, a detoxification process is performed in conjunction with the facility renewal work for the existing elevator EV. The detoxification treatment includes physical removal such as peeling asbestos, confinement treatment that hardens the surface of the application site by chemical solution application, etc. For example, an enclosing process for enclosing and not exposing to the outside.

<< About asbestos treatment equipment >>
As a method of processing such deposits (asbestos), there is a method in which a temporary gondola is hung from the ceiling portion 26, and an operator on the gondola processes deposits on the elevator shaft EVS while raising and lowering the gondola. is there. However, in this case, since the temporary gondola is only hung from the ceiling portion 26, there is a problem that the foot is shaken and safety cannot be secured.

  Therefore, in the present embodiment, as an asbestos treatment facility, a working scaffold 30 for treating asbestos is provided on the upper part of the elevator car 10. Since the elevator car 10 is lifted and lowered by being guided by a guide rail for raising and lowering (guide rail GR described later), the elevator car 10 is stable with less fluctuation than the temporary gondola as described above.

<< About setting the height of the working scaffold >>
Next, the setting of the height of the work scaffold 30 in this embodiment will be described.

  As described above, the elevator car 10 is provided at one end of the rope R, and the counterweight W is provided at the other end. The elevator 19 controls the raising and lowering of the elevator car 10 and the counterweight W. For this reason, as the elevator car 10 moves up and down, the counterweight W moves up and down in the direction opposite to the moving direction of the elevator car 10. Specifically, the counterweight W is lowered when the elevator car 10 is raised, and the counterweight W is raised when the elevator car 10 is lowered.

  In other words, there is always a place where the elevator car 10 and the counterweight W pass each other in the elevator shaft EVS.

  2A and 2B are schematic views showing a positional relationship when the elevator car 10 and the counterweight W pass each other. Here, it is assumed that the counterweight W is raised and the elevator car 10 is lowered. The height of the counterweight W in the vertical direction is h.

  In FIG. 2A, the vertical position of the upper surface of the elevator car 10 and the vertical position of the lower end of the counterweight W are the same (position P). If it becomes such a positional relationship, the worker on the elevator car 10 cannot work (or difficult) on the portion (shown by the hatching) hidden by the counterweight W on the vertical surface (side wall 23) of the elevator shaft EVS. There is a risk.

  Here, the shaded portion is not blocked by the counterweight W when the counterweight W is raised from the position P by the height h of the counterweight W as shown in FIG. 2B. However, at this time, the upper surface of the elevator car 10 is lowered from the position P by h as shown in FIG. 2B.

  Therefore, in order to reliably process the hatched portion in the figure, the height of the work scaffold 30 should be 2 h or more.

  Therefore, in the present embodiment, the height H of the work scaffold 30 is determined to be at least twice the height h of the counterweight W. By doing so, the asbestos in the portion indicated by the oblique lines in the figure can be reliably processed.

<< About the structure of the work scaffold >>
FIG. 3 is a side view for explaining the configuration of the work scaffold 30 of the present embodiment.
As shown in the figure, on the upper part of the elevator car 10, a large number of single-pipe pipes 31 are combined in a vertical direction, a horizontal direction, and an oblique direction to form a framework (handrail, etc.) of the work scaffold 30. Yes. The elevator car 10 is moved (lifted / lowered) in the vertical direction while being guided by the lifting / lowering guide rails GR respectively disposed on the left and right sides of the elevator car 10. The guide rail GR is disposed on the left and right side walls 23 along the vertical direction from the floor portion 28 to the ceiling portion 26 in FIG. 1.
As shown in FIG. 3, the work scaffold 30 includes a two-stage work floor 32 in the vertical direction.

FIG. 4 is a top view of the work floor 32. The upper and lower work floors 32 have the same configuration.
As shown in FIG. 4, the work floor 32 is configured by arranging aluminum rectangular cloth plates 32a, 32b, and 32c. The cloth board 32a is an open / close hatch type cloth board, and a partial opening / closing hatch (a left part of the cloth board 32a) and a trap 34 are mounted. An operator can get on and off the work floor 32 by opening the opening / closing hatch of the cloth board 32a. Further, a baseboard 33 is provided around the work floor 32 (at the end in the horizontal direction).

  In addition, the work scaffold 30 of this embodiment includes a guide member 40, a folding scaffold 50, and a fall prevention facility 60.

<About the guide member 40>
As shown in FIG. 3, the guide member 40 is provided on the side (the right end and the left end) of the upper work floor 32 of the work scaffold 30.

FIG. 5 is an explanatory view of the guide member 40. In this embodiment, the guide rail GR has a T-shaped horizontal section as shown in the figure.
The guide member 40 includes a support member 41 and a rotation member 43.

  One end side of the support member 41 pivotally supports the rotating member 43 in a rotatable manner. Further, the other end side of the support member 41 is fixed to a side portion of the upper work floor 32 in the work scaffold 30 (see FIG. 3).

  The rotating member 43 has an engaging groove 44 that engages with the guide rail GR of the elevator car 10 around the rotating member 43, and rotates along the guide rail GR in a state where the engaging groove 44 is engaged with the guide rail GR.

  By providing such a guide member 40, when the elevator car 10 moves up and down, the lifting and lowering of the work scaffold 30 can be guided. For example, even when an earthquake occurs while the elevator car 10 is stopped, the work scaffold 30 having a height H can be stably held by the guide member 40.

  The installation location of the guide member 40 is not limited to the side portion of the upper work floor 32 of the work scaffold 30 and may be a position that can be engaged with the guide rail GR. For example, you may provide the guide member 40 in the side part of the upper end of the vertical direction of the working scaffold 30. FIG.

<Folding scaffold 50 and fall prevention equipment 60>
As shown in FIG. 3, the folding scaffold 50 is provided on the upper work floor 32 side, and the fall prevention facility 60 is provided on the lower work floor 32 side. The foldable scaffold 50 and the fall prevention facility 60 are provided around the work scaffold 30 so as to surround the work floor 32. Note that the folding scaffold 50 and the fall prevention equipment 60 correspond to a spring-out equipment.
The folding scaffold 50 includes a support member 51, a plate material 53, and a plate material 55.

  The support member 51 is formed of, for example, a single pipe and is provided in two stages in the vertical direction. One end of each support member 51 is provided on the single pipe 31 of the work scaffold 30 so as to be rotatable about the axis of the single pipe 31. Further, the other end of each support member 51 is rotatably provided on the plate member 53. The support member 51 constitutes a handrail when the folding scaffold 50 is jumped to the side wall 23 side of the elevator shaft EVS.

  The plate material 53 is a plate-shaped member made of metal (for example, aluminum), and constitutes a side wall of the folding scaffold 50.

  The plate member 55 is a plate member made of metal (for example, aluminum). One end of the plate member 55 is provided on the single pipe 31 of the work scaffold 30 so as to be rotatable about the axis of the single pipe 31. Note that the plate member 55 and the support member 51 are rotatable between a vertically upward direction and a horizontal direction by a stopper (not shown). Further, the other end of the plate member 55 is rotatably provided at the lower end portion of the plate member 53.

  FIG. 6 is a schematic diagram for explaining the configuration of the fall prevention facility 60. The upper figure of FIG. 6 is a view of the state in which the fall prevention equipment 60 is projected from the side of the side wall 23 of the elevator shaft EVS, and the lower figure stores the fall prevention equipment 60 on the work scaffold 30 side. It is the figure which looked at the state made to see from the top.

  As shown in FIG. 6, the fall prevention facility 60 includes panels 61 provided on the front, back, left, and right sides of the work floor 32 and sheets 62 provided on the corners thereof.

  The panel 61 is a plate member made of metal (for example, aluminum). One end of the panel 61 is provided on the single pipe 31 of the work scaffold 30 so as to be rotatable about the axis of the single pipe 31. Thereby, the other end of the panel 61 can move (bounce and store) between the work scaffold 30 and the vertical surface (side wall 23) of the elevator shaft EVS. Note that the amount of the panel 61 protruding toward the side wall 23 can be adjusted by a chain or a wire (not shown).

  The sheet 62 plays a role in preventing the fall of asbestos or the like that is spread and processed as shown in the upper diagram of FIG. 6 when the panel 61 is ejected to the elevator shaft EVS side. On the other hand, when the panel 61 is stored on the work scaffold 30 side, it is stored between the adjacent panels 61 as shown in the lower diagram of FIG.

  7A to 7C are explanatory diagrams of the operations of the folding scaffold 50 and the fall prevention facility 60. FIG. 7A shows a state when the elevator car 10 (in other words, the work platform 30) is raised and lowered, and FIG. 7C shows a state when the work platform 30 is stopped. FIG. 7B shows the state between FIG. 7A and FIG. 7C.

  When the elevator car 10 is raised and lowered, as shown in FIG. 7A, both the folding scaffold 50 and the fall prevention equipment 60 are housed on the work scaffold 30 side. In this case, the wall portion of the work scaffold 30 is configured by the plate material 53 and the plate material 55 of the folding scaffold 50 and the panel 61 of the fall prevention equipment 60. Thereby, at the time of raising / lowering of the elevator car 10, the operator on the work scaffold 30 can be prevented from falling, and safety can be improved.

  On the other hand, when the elevator car 10 is stopped (in other words, when the asbestos process is performed), as shown in FIG. ) Is bounced to the side.

  By causing the folding scaffold 50 to jump out toward the side wall 23, the plate material 55 can be used as a scaffold, and the work space can be widened. Therefore, work efficiency can be improved. In this case as well, the side wall can be constituted by the plate material 53, and safety can be secured.

  Moreover, the fall asbestos 60 (panel 61, sheet | seat 62) is made to jump toward the side wall 23 side, and it can prevent that the removed asbestos falls under the elevator shaft EVS. Further, the removed asbestos can be collected and placed on the lower work floor 32. As described above, an asbestos storage space can be created in the work scaffold 30, so that it is not necessary to raise and lower the elevator car 10 many times, and the construction period can be shortened and work efficiency can be improved.

  In the present embodiment, the plate material 53, the plate material 55, and the panel 61 are aluminum plate-like members, but may be other than this. For example, a metal other than aluminum may be used. Moreover, materials other than a metal may be sufficient. However, since it is provided on the elevator car 10, it is desirable that it is a lightweight and high-incombustibility material.

  The panel 61 may be a sheet or a net. The sheet 62 may be other than a sheet, for example, a net.

  As described above, in the present embodiment, the work scaffold 30 for processing asbestos in the elevator shaft EVS is provided in the upper part of the elevator car 10 as the deposit processing facility. And the guide member 40 which guides raising / lowering of the work scaffold 30 is provided in the position which can be engaged with the guide rail GR for raising / lowering the elevator car 10. As shown in FIG.

  By doing so, it is possible to improve the stability of the work scaffold 30.
