The notification unit 16 may notify information by at least one of an image, a sound, and light emission.

[0021] <Holding part 17> The mounting device 10 includes a holding portion 17. The holding portion 17 is supported by the main body portion 11. The holding portion 17 is capable of holding the curtain wall 90. The holding portion 17 may be capable of holding a portion of the curtain wall 90, or may be capable of holding the entire curtain wall 90. The holding portion 17 is provided to extend in the depth direction Y.

[0022] As shown in Fig. 2, the retaining portion 17 has a retaining surface 20. The retaining surface 20 is a surface facing upward Z1. The retaining surface 20 is a surface that retains the curtain wall 90. In particular, the retaining surface 20 is a surface that retains the curtain wall 90 so as to face an inner surface 91 of the curtain wall 90. In other words, the retaining portion 17 retains the curtain wall 90 so as not to come into contact with an outer surface 92 of the curtain wall 90.

[0023] The holding portion 17 includes a pair of holding plates 21 and a connecting plate 22. The pair of holding plates 21 and the connecting plate 22 each have a plate shape, but are not limited to this. The pair of holding plates 21 includes a first holding plate 21A and a second holding plate 21B. The pair of holding plates 21 are arranged to be aligned in the width direction X.

The pair of holding plates 21 and the connecting plate 22 are configured separately, but may be configured integrally. In this manner, the holding portion 17 may be U-shaped in a plan view. The upper surfaces of the pair of holding plates 21 form a part of the holding surface 20. The upper surface of the connecting plate 22 forms a part of the holding surface 20.

[0025] The connecting plate 22 is configured to be extendable and contractable in the width direction X. When the connecting plate 22 is extended and contracted in the width direction X, the second holding plate 21B moves in the width direction X. In this manner, the holding portion 17 is extendable and contractable in the width direction X.

[0026] The holding portion 17 includes an attachment portion 18. The attachment portion 18 is provided at an end portion of the holding portion 17 in the second width direction X2.

[0027] The mounting portion 18 includes a retaining connection portion 37. The retaining connection portion 37 is connectable to a vertical frame 95 of the curtain wall 90 that is held on the holding surface 20. The retaining connection portion 37 may be, for example, a hook. This allows the mounting portion 18 to be connectable to a vertical frame 95 of the curtain wall 90 that is held on the holding surface 20.

[0028] In addition, as will be described in detail later, when the curtain wall 90 is held by the holding portion 17, the mounting portion 18 is connectable to one of the vertical frames 95 of the vertically stacked curtain wall 90 that faces upward Z1.

[0029] As shown in Figs. 2 and 4, the holding portion 17 is rotatable about the first shaft 23. Fig. 4 is a view in which the running portion 12 is omitted to facilitate understanding of the invention. The first shaft 23 is an axis along the depth direction Y. The first shaft 23 is provided on the first width direction X1 side of the first holding plate 21A. In other words, the first shaft 23 is provided on the first width direction X1 side of the holding portion 17. In this way, the holding portion 17 is rotatable about the first shaft 23 as a rotation axis.

[0030] 4, the holding portion 17 is rotatable between a first holding position P11 and a second holding position P12 around the first shaft 23. That is, the holding portion 17 is rotatable between the first holding position P11 and the second holding position P12. The first holding position P11 is a position rotated by an angle of 90 degrees or more from the second holding position P12 around the first shaft 23 as a rotation axis, but is not limited to this.

[0031] The holding portion 17 can also move to a third holding position P13. The third holding position P13 is located between the first holding position P11 and the second holding position P12. The third holding position P13 is a position rotated 90 degrees from the second holding position P12 around the first shaft 23 as a rotation axis.

[0032] The first holding position P11 is a position where the holding surface 20 faces the first width direction X1. The first holding position P11 is a position where the posture of the vertically stacked curtain wall 90 can be maintained. In other words, the first holding position P11 is a position where the vertically stacked curtain wall 90 can be removed.

[0033] When the retaining portion 17 is in the first retaining position P11, the attachment portion 18 is located above the retaining surface 20 at Z1. When the retaining portion 17 is in the first retaining position P11, the attachment portion 18 is connectable to one of the vertical frames 95 of the curtain wall 90 held by the retaining portion 17 that faces upward Z1. As a result, when the retaining portion 17 is in the first retaining position P11, the curtain wall 90 held by the retaining portion 17 is attached to the attachment portion 18.

[0034] The third holding position P13 is a position where the holding surface 20 faces the first width direction X1. The third holding position P13 is a position where the vertically stacked curtain wall 90 can be held by the holding portion 17. In other words, the third holding position P13 is a position where the vertically stacked curtain wall 90 can be held.

[0035] The second holding position P12 is a position where the holding surface 20 faces upward Z1. That is, the second holding position P12 is a position where the holding surface 20 is horizontal. The second holding position P12 is a position where the curtain wall 90 is held horizontally. In this embodiment, the second holding position P12 is determined as the original position, but is not limited thereto.

[0036] <Hanging part 19> As shown in Fig. 1 and Fig. 2, the mounting device 10 includes a hanging part 19. The hanging part 19 is supported by the main body 11. The hanging part 19 extends in the depth direction Y. The hanging part 19 may be T-shaped in a plan view. The hanging part 19 is capable of hanging the curtain wall 90 held by the holding part 17.

[0037] The hanging part 19 has a support surface 30. The support surface 30 is a surface facing upward Z1. The support surface 30 is a surface that supports the curtain wall 90. In particular, the support surface 30 is a surface that supports the curtain wall 90 so as to face an inner surface 91 of the curtain wall 90. In other words, the hanging part 19 supports the curtain wall 90 so as not to come into contact with an outer surface 92 of the curtain wall 90.

[0038] The support surface 30 constitutes the same horizontal plane as the holding surface 20 when the holding portion 17 is disposed at the second holding position P12. The support surface 30 is a surface that supports the curtain wall 90 held by the holding portion 17 together with the holding surface 20.

[0039] The hanging part 19 includes an extension portion 31, a base end portion 32, and a tip end portion 33. The extension portion 31 extends in the depth direction Y. The base end portion 32 is located further in the first depth direction Y1 than the extension portion 31. The tip end portion 33 is located further in the second depth direction Y2 than the extension portion 31. In other words, the tip end portion 33 is located in the opposite direction to the base end portion 32 in the depth direction Y. The extension portion 31 and the base end portion 32 are located between the pair of retaining plates 21 in the width direction X. In this way, by configuring the retaining portion 17 to be U-shaped in a plan view and configuring the hanging part 19 to be T-shaped in a plan view, it is possible to save space for the retaining portion 17 and the hanging part 19 and to stably retain the curtain wall 90.

[0040] The tip portion 33 includes a pair of protruding portions 34. That is, the hanging part 19 includes a pair of protruding portions 34. The pair of protruding portions 34 extend in the direction along the width direction X, respectively. The hanging part 19 includes a hanging connection part 35. The hanging part 19 may include a pair of hanging connection parts 35. The hanging connection parts 35 are provided on the protruding part 34. That is, the hanging connection parts 35 are provided on the tip part 33. The hanging connection parts 35 are connectable to the curtain wall 90. The hanging connection parts 35 may be connectable to the upper frame 93 of the curtain wall 90. The hanging connection parts 35 may include a wire. The hanging connection parts 35 are connectable to the curtain wall 90 via the wire. The hanging connection parts 35 can pay out and take up the wire. In this way, the hanging connection parts 35 are connectable to the curtain wall 90 at the tip part 33.

[0041] As shown in Figs. 2 and 5, hanging portion 19 is rotatable about second axis 36. Fig. 5 is a diagram in which running portion 12 and holding portion 17 are omitted to facilitate understanding of the invention. Second axis 36 is an axis along width direction X. Second axis 36 is located at base end 32. In other words, second axis 36 is located at base end 32. In this manner, hanging portion 19 is rotatable about second axis 36 as a rotation axis.

[0042] 5, the hanging part 19 is rotatable between a horizontal position P21 and a first hanging position P22 around the second shaft 36. That is, the hanging part 19 is rotatable between the horizontal position P21 and the first hanging position P22. The first hanging position P22 is a position rotated 90 degrees or more from the horizontal position P21 around the second shaft 36 as a rotation axis, but is not limited to this.

[0043] The horizontal position P21 is a position in which the hanging connection portion 35 is disposed in the second depth direction Y2. The horizontal position P21 is a position at which the curtain wall 90 is maintained horizontal. In particular, the horizontal position P21 is a position at which the curtain wall 90 held by the holding portion 17 at the second holding position P12 is maintained horizontal. In this embodiment, the horizontal position P21 is defined as the original position, but is not limited thereto.

[0044] The first hanging position P22 is a posture in which the hanging connection portion 35 of the hanging portion 19 is disposed in the first depth direction Y1. The first hanging position P22 is a position for hanging the curtain wall 90. In particular, the first hanging position P22 is a position for hanging the curtain wall 90 that was held by the holding portion 17 at the second holding position P12.

[0045] Furthermore, hanging part 19 is configured to be extendable and contractable in the extension direction of extension part 31. When hanging part 19 is disposed in horizontal position P21, the extension direction is along the depth direction Y. In particular, extension part 31 is configured to be extendable and contractable such that the distance between base end 32 and tip end 33 changes.

[0046] As a specific example, the hanging part 19 is displaceable from a first hanging position P22 to a second hanging position P23. The second hanging position P23 is a position where the hanging connection part 35 is farther away from the base end part 32 than the first hanging position P22. At least the first hanging position P22 corresponds to an example of the hanging position, but the second hanging position P23 may be included in the hanging position.

[0047] 2 and 6, the pair of protrusions 34 are configured to be extendable and contractable in the width direction X. In FIG. 6, the running portion 12 and the holding portion 17 are omitted in order to facilitate understanding of the invention. When the pair of protrusions 34 are extended and contracted in the width direction X, the pair of suspension connection portions 35 each move in the width direction X. This makes it possible to adjust the positions of the pair of suspension connection portions 35 to match the curtain wall 90 held by the holding portion 17.

[0059] <Curtain wall installation process> Next, the curtain wall mounting process will be described with reference to Figs. As shown in Fig. 8 and Fig. 9(A), in step S10, a first holding position driving step is performed. Fig. 9 is a diagram in which the traveling unit 12 is omitted for ease of understanding of the invention. The first holding position driving step is a step executed by the control unit 40 based on an operation signal from the operation unit 15. Based on the operation signal from the operation unit 15, the control unit 40 drives the first drive unit 41 to rotate the holding unit 17 from the second holding position P12 to the first holding position P11. As a result, the holding surface 20 faces the first width direction X1.

[0060] Furthermore, the control unit 40 may drive the second drive unit 42 to move the second holding plate 21B in the width direction X based on an operation signal from the operation unit 15. As a result, the holding connection unit 37 is disposed at a position corresponding to the height of the vertically stacked curtain walls 90. Furthermore, the holding connection unit 37 is disposed at a position corresponding to the width of the curtain wall 90.

[0061] In step S11, a first connection step is performed. In the first connection step, a worker connects the vertically stacked curtain wall 90 to the holding connection portion 37. More specifically, the worker attaches a hanging jig to the upper frame 93 of the vertically stacked curtain wall 90. The worker connects the hanging jig attached to the vertical frame 95 facing the upper Z1 of the vertically stacked curtain wall 90 to the holding connection portion 37. This allows the worker to connect the curtain wall 90 to the holding portion 17 while it is in the vertically stacked position.

[0062] As shown in FIG. 8 and FIG. 9(B), in step S12, a second holding position driving step is performed. The second holding position driving step is a step executed by the control unit 40 based on an operation signal from the operation unit 15. Based on the operation signal from the operation unit 15, the control unit 40 drives the first drive unit 41 to rotate the holding unit 17 from the first holding position P11 to the second holding position P12. As a result, the vertically stacked curtain wall 90 is taken out in a state where it is connected to the holding connection unit 37. Then, the taken-out curtain wall 90 is held by the holding unit 17. Thereafter, the vertically stacked curtain wall 90 is held in a state where it is laid flat on the mounting device 10.

[0063] In step S13, a second connection step is performed. In the second connection step, a worker connects the wire of the suspension connection part 35 to the upper frame 93 of the curtain wall 90 held by the holding part 17. In detail, the control part 40 may drive the fourth drive part 44 to move the suspension connection part 35 in the width direction X based on an operation signal from the operation part 15. As a result, the suspension connection part 35 is disposed at a position corresponding to the width of the curtain wall 90 held by the holding part 17. The worker connects the suspension jig attached to the upper frame 93 of the curtain wall 90 to the suspension connection part 35. As a result, the curtain wall 90 laid flat on the mounting device 10 and the suspension part 19 are connected.

[0064] As shown in FIG. 8 and FIG. 10(A), a traveling process is performed in step S14. The traveling process is a process executed by the control unit 40 based on an operation signal from the operation unit 15. The control unit 40 drives the traveling drive unit 47 to travel the installation device 10 based on an operation signal from the operation unit 15. As a result, the installation device 10 transports the curtain wall 90 to the edge of the outer wall of the upper floor 98 of the building 99 while holding the curtain wall 90. In addition, the installation device 10 transports the curtain wall 90 so that the first depth direction Y1 faces the edge of the outer wall of the building 99. The worker removes the hanging jig attached to one vertical frame 95 of the curtain wall 90 from the holding connection part 37, and removes the hanging jig from one vertical frame 95 of the curtain wall 90.

[0065] 8 and 10(B), in step S15, a hanging position driving process is performed. The hanging position driving process is a process executed by control unit 40 based on an operation signal from operation unit 15. Based on the operation signal from operation unit 15, control unit 40 drives third drive unit 43 to rotate hanging part 19 from horizontal position P21 to first hanging position P22.

[0066] Control unit 40 may also drive fifth drive unit 45 to displace hanging part 19 from first hanging position P22 to second hanging position P23, based on an operation signal from operation unit 15. Control unit 40 may also drive connection drive unit 46 to pay out the wire of suspension connection unit 35, based on an operation signal from operation unit 15.

[0067] In particular, while the hanging part 19 is rotating from the horizontal position P21 to the first hanging position P22, the inner surface 91 of the hanging curtain wall 90 comes into contact with the support surface 30. As a result, the curtain wall 90 is supported by the support surface 30. Then, while the curtain wall 90 is suspended from the hanging part 19, the lower frame 94 is suspended outward from the upper floor 98 in accordance with the rotation of the hanging part 19. Then, in accordance with the rotation of the hanging part 19, the curtain wall 90 suspended from the hanging part 19 moves such that the lower frame 94 is suspended outward from the upper floor 98.

[0068] As a result, the mounting device 10 suspends the held curtain wall 90 from the upper floor 98. In other words, the suspension position driving process can also be called a suspending process for suspending the held curtain wall 90 from the upper floor 98.

[0069] As shown in Fig. 8 and Fig. 11(A), in step S16, a hanging process is performed. The hanging process is a process executed by the control unit 40 based on an operation signal from the operation unit 15. The hanging process is a process in which the mounting device 10 hangs the curtain wall 90. Based on the operation signal from the operation unit 15, the control unit 40 drives the connection drive unit 46 to pay out the wire of the hanging connection unit 35.

[0070] Control unit 40 may also drive third drive unit 43 to rotate hanging part 19 around second shaft 36 as a rotation axis, based on an operation signal from operation unit 15. Control unit 40 may also drive fifth drive unit 45 to extend and retract hanging part 19, based on an operation signal from operation unit 15.

[0071] In this way, the mounting device 10 can suspend the curtain wall 90 connected to the suspension connection portion 35 from the upper floor 98 to the installation floor 97. This allows the curtain wall 90 to be suspended from the outside of the building 99 to the installation floor 97. In addition, the mounting device 10 can suspend the curtain wall 90 so that the outer surface 92 of the curtain wall 90 faces the outside of the building 99 without inverting the curtain wall 90 suspended from the upper floor 98.

[0072] As shown in Figures 8 and 11(B), an installation process is performed in step S17. The installation process is a process of installing the curtain wall 90 to the installation floor 97. More specifically, on the installation floor 97, workers place the lower frame 94 of the curtain wall 90 on the upper frame 93 of the curtain wall 90 that has already been installed on the floor one floor below. On an upper floor 98, workers fix the upper frame 93 of the curtain wall 90 to the framework of the upper floor 98 via fastening members (not shown). After the curtain wall 90 is installed, the wires of the suspension connection parts 35 are removed from the curtain wall 90.

[0073] <Actions and Effects of the First Embodiment> The operation and effects of the embodiment will be described. (1-1) The mounting device 10 includes a holding unit 17 and a hanging unit 19. The holding unit 17 is rotatable about a first axis 23 along the depth direction Y as a rotation axis, and is capable of holding the curtain wall 90. The hanging unit 19 is rotatable about a second axis 36 along the width direction X as a rotation axis, and is capable of suspending the curtain wall 90 held by the holding unit 17. The holding unit 17 is rotatable to a first holding position P11 at which the vertically stacked curtain wall 90 can be held, and a second holding position P12 at which the curtain wall 90 is held horizontally. The hanging unit 19 is rotatable to a first hanging position P22 at which the holding unit 17 suspends the curtain wall 90 held at the second holding position P12. This improves the convenience of mounting the curtain wall 90.

[0074] In detail, when the curtain wall 90 is attached to the attachment floor 97, by using the attachment device 10, it is not necessary to arrange a large-sized suspending device such as a floor crane or a telpher on a floor higher than the upper floor 98. This makes it possible to reduce the number of floors used for the work when attaching the curtain wall 90 to the attachment floor 97. In addition, it is possible to shorten the period from the framework formation process, such as pouring concrete, to the start of the curtain wall attachment process. In addition, by using the attachment device 10 when attaching the curtain wall 90 to the attachment floor 97, it is not necessary to arrange a large-sized suspending device such as a tower crane on the outside of the building 99. In this way, by using the attachment device 10, it is possible to reduce the amount of work for each worker and to reduce the number of workers without using various suspending devices larger than the attachment device 10. Therefore, it is possible to improve the convenience of attaching the curtain wall 90. In addition, the attachment device 10 is used less frequently in processes other than the curtain wall attachment process, and there is a high possibility that the attachment device 10 will be occupied in the curtain wall attachment process. Therefore, it is possible to improve the convenience of attaching the curtain wall 90.

[0075] Furthermore, by using the installation device 10, the worker does not need to lay the vertically stacked curtain walls 90 flat. This makes the installation work of the curtain wall 90 easier. This reduces the workload of each worker and also reduces the number of workers. This improves the convenience of installing the curtain wall 90.

[0076] In addition, the mounting device 10 can stably hold the curtain wall 90 in a flat-laid state. Also, the mounting device 10 can stably transport the curtain wall 90 in a flat-laid state. Therefore, by using the mounting device 10, the convenience of mounting the curtain wall 90 can be improved.

[0077] Conventionally, depending on the conditions for installing the curtain wall 90, such as the method of installing the curtain wall 90 and the surrounding environment in which the curtain wall 90 is installed, there were cases where the curtain wall 90 could not be installed. Therefore, in this embodiment, the installation device 10 is configured to install the curtain wall 90 from the outside of the building 99 at the installation floor 97. Therefore, even if there is an obstacle on the installation floor 97, the curtain wall 90 can be installed on the installation floor 97 by using the installation device 10 as long as there is no obstacle on the upper floor 98. In addition, by using the installation device 10, the last curtain wall 90 of the multiple curtain walls 90 to be installed on the installation floor 97 can also be easily installed. Therefore, the convenience of installing the curtain wall 90 can be improved.

[0078] (1-2) The installation device 10 includes a holding connection part 37 that can be connected to the holding part 17 so as to suspend the curtain wall 90 when the holding part 17 is in the first holding position P11. Therefore, the worker can connect the vertically stacked curtain wall 90 to the holding connection part 37, thereby making it possible to hold the curtain wall 90 on the holding part 17 according to the displacement of the holding part 17. In particular, the curtain wall 90 can be stably held regardless of the material constituting the curtain wall 90, such as a curtain wall 90 including a glass member. In this way, the work of holding the curtain wall 90 becomes easier. This makes it possible to reduce the workload of each worker and also to reduce the number of workers. Therefore, the convenience of installing the curtain wall 90 can be improved.

[0079] (1-3) The hanging part 19 is extendable in the extension direction. This allows for flexible adjustment of the path along which the curtain wall 90 is hung. This improves the convenience of installing the curtain wall 90.

[0080] (1-4) The mounting device 10 includes a first drive unit 41 that rotates the holding unit 17 around the first shaft 23 as a rotation axis. Therefore, the first drive unit 41 can rotate the holding unit 17 around the first shaft 23 as a rotation axis. In this way, the worker does not need to lay the vertically stacked curtain wall 90 flat, and the work of holding the curtain wall 90 becomes easier. This reduces the workload of each worker and also reduces the number of workers. Therefore, by using the mounting device 10, the convenience of mounting the curtain wall 90 can be improved.

[0081] (1-5) The mounting device 10 includes a third drive unit 43 that rotates the hanging part 19 around the second shaft 36 as a rotation axis. Therefore, the third drive unit 43 can rotate the hanging part 19 around the second shaft 36 as a rotation axis. In this way, the work of hanging the curtain wall 90 becomes easier. This makes it possible to reduce the workload of each worker and also to reduce the number of workers. Therefore, by using the mounting device 10, it is possible to improve the convenience of mounting the curtain wall 90.

[0082] (1-6) The suspension connection part 35 is movable in the width direction X. Therefore, when connecting the curtain wall 90 and the suspension connection part 35, the position of the suspension connection part 35 can be adjusted according to the width of the curtain wall 90. Therefore, the convenience of installing the curtain wall 90 can be improved.

[0083] (1-7) The holding portion 17 can hold the curtain wall 90 without abutting against the outer surface 92 of the curtain wall 90. The hanging portion 19 can hang the curtain wall 90 so that the outer surface 92 of the curtain wall 90 faces the outside of the building 99 without turning the curtain wall 90 over. This can reduce the workload of each worker and can also reduce the number of workers. Therefore, the convenience of installing the curtain wall 90 can be improved.

[0084] (1-8) The mounting device 10 is equipped with a ball wheel type running unit 12. This allows the mounting device 10 to run smoothly even if there is a step on the installation surface 96. This reduces the workload of each worker and also reduces the number of workers. Therefore, the convenience of mounting the curtain wall 90 can be improved.

[0085] [Second embodiment] Next, a second embodiment will be described. In the following description, the same configuration as in the embodiment already described will be omitted or simplified, and the configuration different from the embodiment already described will be mainly described.

The mounting portion 38 is provided at an end portion in the first width direction X1 of the first holding plate 21A. The mounting portion 38 protrudes upward Z1 from the holding surface 20.

[0087] The mounting portion 18 and the mounting portion 38 are arranged side by side in the width direction X with the holding surface 20 in between. The mounting portion 38 abuts against the other of the vertical frames 95 of the curtain wall 90 held by the holding surface 20.

[0088] The second holding plate 21B moves in the width direction X, thereby making it possible to adjust the distance between the attachment portion 18 and the mounting portion 38. This allows the mounting portion 38 to stably hold the curtain wall 90 on the holding portion 17.

[0089] <Actions and Effects of the Second Embodiment> The operation and effects of the second embodiment will be described. (2-1) On the placement section 38, the other of the vertical frames 95 of the curtain wall 90 held by the holding section 17 can be placed. Therefore, the curtain wall 90 can be stably held in the process up to laying the vertically stacked curtain wall 90 flat on the holding section 17.

This makes it possible to reduce the workload of each worker and also to reduce the number of workers. Therefore, it is possible to improve the convenience of mounting the curtain wall 90.

[0101] [Fourth embodiment] Next, a fourth embodiment will be described. 16, in the fourth embodiment, the extension portion 31 may be rotatable around a first rotation axis 39A relative to the base end portion 32. In this case, the extension portion 31 and the base end portion 32 are separate bodies. The first rotation axis 39A is along a direction intersecting the extension direction. The attachment device 10 may include a first rotation drive unit for rotating the extension portion 31.

[0102] The tip portion 33 may be rotatable about a second rotation axis 39B relative to the extension portion 31. In this case, the extension portion 31 and the tip portion 33 are separate bodies. The second rotation axis 39B is along a direction intersecting the extension direction. The attachment device 10 may include a second rotation drive unit for rotating the tip portion 33.

[0103] The angle at which the extension portion 31 rotates relative to the base end portion 32 and the angle at which the tip portion 33 rotates relative to the extension portion 31 may be adjusted so that the pair of protrusions 34 protrude horizontally from the tip portion 33. In detail, the angle at which the extension portion 31 rotates relative to the base end portion 32 and the angle at which the tip portion 33 rotates relative to the extension portion 31 are the same with respect to reverse rotation, so that the pair of protrusions 34 can be protruded horizontally from the tip portion 33. This allows the curtain wall 90 connected to the hanging connection portion 35 to be moved horizontally.

[0104] <Actions and Effects of the Fourth Embodiment> The operation and effects of the fourth embodiment will be described. (4-1) The extension portion 31 can rotate relative to the base end portion 32 in a direction intersecting the extension direction. This allows for flexible adjustment of the path along which the curtain wall 90 is suspended. This improves the convenience of installing the curtain wall 90.

[0105] (4-2) The tip portion 33 can rotate in a direction intersecting the extension direction with respect to the extension portion 31. This allows for flexible adjustment of the path along which the curtain wall 90 is suspended. This improves the convenience of installing the curtain wall 90.

[0106] (4-3) In addition, by adjusting the angle at which the extension portion 31 rotates relative to the base end portion 32 and the angle at which the tip portion 33 rotates relative to the extension portion 31, the pair of protrusions 34 can be maintained to protrude horizontally. This allows the curtain wall 90 connected to the suspension connection portion 35 to be moved horizontally. Therefore, the convenience of installing the curtain wall 90 can be improved.

[0107] [Example of change] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0108] The suspension part 19 may include three or more suspension connection parts 35. The suspension connection parts 35 do not have to be able to pay out and take up the wire. The suspension connection parts 35 do not have to include a wire.

[0109] The holding portion 17 may comprise one or more holding connections 37. The holding connections 37 may comprise a wire. The holding connections 37 may be capable of unwinding and winding the wire.

[0110] The holding portion 17 does not have to include the holding connection portion 37. In this case, a worker may use a device such as an electric chain block to hold the vertically stacked curtain walls 90 to the holding portion 17.

[0111] The holding portion 17 may be rotatable about the first shaft 23 as an axis of rotation up to an angle of 90 degrees from the second holding position P12, but may be unable to rotate to an angle greater than 90 degrees from the second holding position P12.

[0112] The holding unit 17 may be extendable and contractable in the depth direction Y. As a specific example, the holding unit 17 may be extendable and contractable so as to protrude in the first depth direction Y1. Also, each of the pair of holding plates 21 may be extendable and contractable in the second depth direction Y2. In this case, the operation unit 15 and the notification unit 16 may be disposed at a position on the main body 11 different from the second depth direction Y2 side.

[0113] The protruding portion 34 may not protrude in the width direction X from the tip portion 33. The protruding portion 34 may be expandable in the width direction X relative to the extending portion 31 so as to change from a state in which it does not protrude from the tip portion 33 in the width direction X to a state in which it protrudes in the width direction X from the tip portion 33. In this case, the tip portion 33, together with the extending portion 31 and the base end portion 32, may be located between the pair of holding plates 21 in the width direction X. In this way, the hanging portion 19 may be I-shaped when viewed from the first depth direction Y1 side, or may be displaced into a T-shape when viewed from the first depth direction Y1 side.

[0114] The hanging part 19 may move in the vertical direction Z. This can increase the angle at which the hanging part 19 can rotate around the second shaft 36 as the rotation axis. As a specific example, the hanging part 19 may rotate more than 180 degrees around the second shaft 36 as the rotation axis. In this case, the mounting device 10 may include a seventh drive unit that moves the hanging part 19 in the vertical direction Z, for example, in the same manner as the third drive unit 43. The seventh drive unit includes a drive source that moves the hanging part 19 in the vertical direction Z. The seventh drive unit may include a motor as the drive source. The seventh drive unit may include a power transmission unit that transmits power from the drive source. The control unit 40 is connected to the seventh drive unit. The control unit 40 transmits a drive signal to the seventh drive unit. As a result, the control unit 40 controls the seventh drive unit.

[0115] The first shaft 23 may be located on the second width direction X2 side. That is, the holding portion 17 may rotate so that the holding surface 20 faces the second width direction X2. Also, the first holding position P11 may be a position where the holding surface 20 faces the second width direction X2. Also, the first shaft 23 may be located on both the first width direction X1 side and the second width direction X2 side. Thereby, the holding portion 17 may rotate so that the holding surface 20 faces the first width direction X1 in some cases and so that the holding surface 20 faces the second width direction X2 in other cases.

[0116] The mounting device 10 may be remotely operable by an operator. In this case, it is possible to reduce the chances of the operator working near the exterior wall of the upper floor 98 of the building 99. This can improve the convenience of mounting the curtain wall 90 and can also improve the safety of the operator.

[0117] The mounting device 10 does not have to be arranged on the upper floor 98. As a specific example, the mounting device 10 may be arranged on a floor higher than the upper floor 98. The mounting device 10 may be arranged on the mounting floor 97. The mounting device 10 may mount the curtain wall 90, which is temporarily placed on the mounting floor, to the mounting floor from inside the building.

[0118] The curtain wall 90 may have a joiner between the upper frame 93 and the lower frame 94, which connects to the vertical frames 95 at both end portions. The curtain wall 90 may have at least one of the upper frame 93, the lower frame 94, and the vertical frames 95 not in a frame shape.

[0119] The term "at least any" as used herein means one or more of the desired options. As an example, the term "at least any" as used herein means only one option or both options if the number of options is two. As another example, the term "at least any" as used herein means only one option or any combination of two or more options if the number of options is three or more.

[0120] [Note] Next, the technical ideas that can be understood from the above-described embodiment and other examples will be described below. (A) The hanging portion is rotatable between a horizontal position in which the curtain wall held by the holding portion in the second holding position remains horizontal, and a hanging position in which the curtain wall held by the holding portion in the second holding position is hung.

[0121] (B) The curtain wall mounting device includes a first drive unit that rotates the holding portion around the first axis as a rotation axis, and a third drive unit that rotates the hanging portion around the second axis as a rotation axis.

[0122] (C) The curtain wall mounting device comprises a main body portion that supports the holding portion and the hanging portion, and a running portion that supports the main body portion and is capable of running horizontally. (D) The retaining portion has a retaining surface that retains the curtain wall and an attachment portion that protrudes vertically from the retaining surface when the retaining portion is positioned in the second retaining position, and the attachment portion has a retaining connection portion that can be connected to suspend the vertically stacked curtain wall.
