Further, the recessed portion 71a is positioned on the right side in the left-right direction with the end-side vertical frame member 71 attached, and the recessed portion 73a is positioned on the lower side in the up-down direction with the upper frame member 73 attached. ing. That is, the end-side vertical frame member 71 and the upper frame member 73 are attached so that the recesses 71a and 73a are located on the shaft entrance 1a side.

  The boundary-side vertical frame member 72 has a rectangular horizontal cross section, and the surface 72a that faces the elevator hole 7 when attached is located at the recesses 71a and 73a of the end-side vertical frame member 71 and the upper frame member 73. It is formed so as to be flush with the surfaces 71 b and 73 b facing the hole 7.

  For this reason, when the attachment frame 70 is formed by the end-side vertical frame member 71, the boundary-side vertical frame member 72, and the upper frame member 73, the recesses 71a and 73a of the end-side vertical frame member 71 and the upper frame member 73 are formed. Thus, the surfaces 71b and 73b facing the elevator hole 7 and the surface 72a facing the elevator hole 7 of the boundary side vertical frame member 72 are flush with each other, and the side of the end side vertical frame member 71 opposite to the shaft entrance 1a and the upper frame member 73 The upper part protrudes toward the elevator hall 7 from the recesses 71a and 73a. At this time, the part where the end-side vertical frame member 71 protrudes and the part of the upper frame member 73 which protrudes toward the elevator hall 7 are arranged so as to be connected to each other.

  And the surface 71b and 73b which face the elevator hall 7 in the recessed parts 71a and 73a of the end side vertical frame material 71 and the upper frame material 73 which make the same surface, and the surface 72a which faces the elevator hole 7 of the boundary side vertical frame material 72, Is provided with a sheet-like magnet 75. Here, the square pipe 31 forming the communication opening is the equipment frame portion, and the equipment frame portion formed by the square pipe 31 forming the communication opening that is attracted to the mounting frame 70 by the magnetic force of the magnet 75 is engaged. It corresponds to an example of a part.

  When connecting the security room 10 to the elevator shaft 1, first, the caster 21 is used to carry the front chamber 11 and the two-chamber unit 13 into the elevator hall 7. The security room 10 is assembled by bonding. Next, out of the metal square pipes 31 forming the communication openings 36 of the assembled security room 10, the two square pipes 31 provided on the left and right sides and the two left and right square pipes 31 are connected to the upper ends. The square pipe 31 connected by the portion abuts on the magnet 75 provided on the mounting frame 70. When the three square pipes 31 forming the communication opening 36 are brought into contact with the magnet 75 provided on the mounting frame 70, the upper part and the three sides on the left and right are hermetically connected by the magnetic force of the magnet 75.

  Next, as shown in FIG. 5, a closing plate 76 having an L-shaped cross section is fixed to the lower square pipe 31 that forms the communication opening 36.

  The closing plate 76 is placed on the lower square pipe 31 and fixed thereon, and a hanging plate portion 76b is suspended from the edge of the placing plate portion 76a on the elevator shaft 1 side. And is attached so as to cover the entire communication opening 36 in the left-right direction. The hanging plate portion 76 b is extended so that the lower edge 76 c is close to the floor surface of the elevator hall 7 when the mounting plate portion 76 a is fixed to the square pipe 31.

  The blocking plate 76 is formed between the lower edge 76c and the floor surface of the elevator hall 7 after the mounting plate portion 76a is fixed to the square pipe 31, and the left and right edges of the hanging plate portion 76b and the end side vertical frame. A space between the material 71 and the boundary side vertical frame material 72 is lined with an adhesive tape 77. When the closing plate 76 is attached and glazed, the security room 10 is airtightly connected to the elevator shaft 1.

  In a state where the security room 10 and the elevator shaft 1 are airtightly connected, the opening / closing port 39b of the cover sheet 39 provided on each of the elevator shaft 1 side and the security room 10 side is opened, and the edge of the opening / closing port 39b is opened. Along with the adhesive tape, the asbestos in the elevator shaft 1 is removed. When the asbestos process is temporarily interrupted, the opening / closing port 39b of the cover sheet 39 provided on the elevator shaft 1 side and the security room 10 side is closed, and the closed fastener 39a portion is adhesive tape. The shaft door 1a and the security room 10 are disconnected from each other, and the security room 10 is moved out of the elevator hall 7 using the casters 21. When processing asbestos again, the security room 10 is carried into the elevator hall 7 and connected to the shaft entrance / exit 1a. At this time, when it is necessary to separate the front chamber 11 and the two-chamber unit 13 when the security room 10 is carried in, a cover sheet 39 is provided at the junction between the front chamber 11 and the two-chamber unit 13 and the front chamber 11 The chamber 11 and the two-chamber unit 13 can be moved separately.

  According to the method for removing asbestos from the elevator shaft 1 and the security room 10 used for removing asbestos from the elevator shaft 1 according to the present embodiment, when processing asbestos in the elevator shaft 1, the security room is provided at the shaft entrance 1a. When 10 is connected and asbestos is not processed, the connection between the security room 10 and the shaft entrance / exit 1a is released and the security room 10 is moved, so that the elevator hall 7 can be used effectively. Moreover, since the security room 10 is equipped with the caster 21, it is easy to move. For this reason, for example, when asbestos processing is performed over a plurality of days, when processing is performed only at night, the security room 10 is connected to the shaft entrance 1a at night and connected to the shaft entrance 1a at noon. It is easy to release the connection and move out of the elevator hall 7. For this reason, the elevator hall 7 can be secured more widely during the daytime when there are many users of the elevator hall 7.

  In addition, before the connection between the shaft doorway 1a and the security room 10 is released, the shaft doorway 1a and the security room 10 are sealed with the cover sheet 39, so that the connection with the shaft doorway 1a is released. Asbestos removal processing prevents asbestos floating in the elevator shaft 1 and the security room 10 from diffusing outside. For this reason, it is possible to isolate | separate the security room 10 from the shaft entrance / exit 1a, without diffusing asbestos outside.

  Further, when removing asbestos in the elevator shaft 1, the space between the cover sheet 39 of the open communication opening 36 and the cover sheet 39 of the shaft entrance / exit 1a is covered with an adhesive tape or the like. Asbestos that is scattered by the air does not enter between the cover sheet 39 of the communication opening 36 and the cover sheet 39 of the shaft doorway 1a. For this reason, even when the connection between the security room 10 and the shaft entrance / exit 1a is released, there is no asbestos on the outside of each cover sheet 39, so the connection with the shaft entrance / exit 1a can be performed without scattering the asbestos outside. The unlocked security room 10 can be moved.

  Moreover, it is possible to provide the facility entrance 10a and the door 51a according to the direction of the shaft entrance 1a, the shape of the elevator hall 7, and the like.

  In this embodiment, although the example which provided the door 51a in the side along the depth direction of the elevator shaft 1 of the security room 10 was demonstrated, the side along the direction which cross | intersects the depth direction of the elevator shaft 1 which has the door 51a. Therefore, the facility entrance 10a can be easily provided on the desired side.

  Moreover, since the air shower room 14, the front room 11, and the changing room 17 which the security room 10 has are arranged side by side in the direction along the depth direction of the elevator shaft 1 at the shaft entrance 1a, It is possible to secure a space in the direction intersecting the depth direction of the elevator shaft 1 with respect to the room 10. For this reason, for example, when the shaft entrance / exit 1a is provided at the end of the elevator hall 7 in the direction intersecting the depth direction of the elevator shaft 1, the elevator hall 7 can be further opened even when asbestos processing is performed. It can be used widely.

  Moreover, since the front room 11, the air shower room 14, and the changing room 17 which the security room 10 has are arranged side by side in the direction intersecting the depth direction of the elevator shaft 1 at the shaft entrance 1a, in the elevator hall 7, It is possible to secure a space on the side opposite to the elevator shaft 1 with respect to the security room 10. For this reason, for example, even if the security room 10 is installed in the elevator hall 7 whose width in the direction along the depth direction of the elevator shaft 1 is narrow, the elevator hall 7 can be used more widely.

  Moreover, since the caster 21 is provided in the security room 10, the arrangement can be easily changed.

  In addition, since the front chamber frame 32 of the security room 10 is formed of a metal square pipe 31, and the magnet 75 is provided on the mounting frame 70 provided at the shaft entrance 1a, the security room 10 uses the magnetic force of the magnet 75. 10 can be easily connected to the shaft entrance / exit 1a via an attachment frame 70 provided on the shaft entrance / exit 1a, and can be easily detached from the shaft entrance / exit 1a by being detached from the attachment frame 70. . In the present embodiment, the example in which the magnet 75 is provided on the attachment frame 70 has been described. However, a magnet may be provided on the front chamber frame side and connected to the metal attachment frame by a magnetic force. In this case, a square pipe that forms a front chamber frame and forms a communication opening, and a magnet provided on the square pipe correspond to an example of the engaging portion.

FIG. 8 is a diagram illustrating a modification of the security room, the shaft doorway, and the connection method.
The connection method between the security room 10 and the shaft entrance / exit 1a is not limited to the magnetic force of the magnet 75.

The room 10 may be connected to the shaft entrance / exit 1a.

  For example, the door 5 of the elevator EV is provided behind the wall surface 2b along the left-right direction of the wall 2 of the elevator hall 7, and the wall 2 of the elevator hall 7 extends in the depth direction between the door 5 and the wall surface 2b. Suppose that it has the side wall part 2a which faces each other along.

  The security room 10 is provided with a member such as a panel member 36a that protrudes from the left and right square pipes 31 forming the communication opening 36 toward the elevator shaft 1 and faces the side wall 2a. The panel member 36a is provided with a pressing member 80 having a bolt portion 80a that is screwed to the panel member 36a and a contact portion 80b that contacts the side wall portion 2a at the tip of the bolt portion 80a.

  The pressing member 80 has a head portion of the bolt portion 80a located on the opposite side of the panel material 36a, that is, on the inner side of the shaft entrance 1a with respect to the panel material 36a, and on the outer side of the shaft entrance 1a. Is screwed to the panel material 36a. For this reason, when the bolt part 80a is tightened, the contact part 80b is configured to move outward from the center side of the shaft entrance 1a. For this reason, when the bolt portion 80a is tightened, the interval between the contact portions 80b of the pressing members 80 provided on the left and right panel members 36a, that is, the interval in the width direction of the shaft entrance / exit is increased. For this reason, the panel member 36a provided in the security room 10 is inserted between the opposing side wall parts 2a, and the bolt part 80a of the pressing member 80 provided on the left and right panel members 36a is tightened, whereby the security room 10 is shafted. It is attached to the entrance / exit 1a.

  Thereafter, the security room 10 and the shaft entrance / exit 1a are hermetically connected by stitching between the communication opening 36 of the security room 10 and the side wall 2a with an adhesive tape 77 or the like. In this case, the pressing member 80 provided on the panel member 36a that protrudes toward the elevator shaft 1 from the square pipe 31 that forms the communication opening 36, which is on the elevator shaft 1 side of the security room 10, is connected to the shaft entrance 1a. The shaft entrance / exit 1a is formed on the outer side of the shaft, and the shaft entrance / exit is connected to the shaft entrance / exit 1a by being moved in the width direction between the side walls 2a facing each other. Even so, the security room 10 can be easily provided. In this case, the pressing member 80 corresponds to an example of the engaging portion.
