Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, at the outer peripheral portion of a structure, it is conceivable to install an exterior material in an opening outside the slab from above the slab and dispose the upper end portion of the exterior material inside the opening.

[0007] However, in the method for installing exterior materials disclosed in Patent Document 1, the exterior material is transported to the outside through the opening of the structure, making it difficult to position the upper end of the exterior material inside the opening, and there is room for improvement in this respect.

[0008] In consideration of the above facts, the present invention aims to position the upper end of the exterior material inside the opening on the outer perimeter of a structure. [Means for solving the problem]

[0009] The method for installing exterior cladding according to claim 1 is a method for installing exterior cladding on the outer periphery of a structure, wherein exterior cladding is installed on a slab and into an opening on the outside of the slab, comprising: an inclination step of tilting the exterior cladding suspended on the slab by a suspension member of a suspension machine such that the lower end is located outward relative to the upper end, with the upper end positioned inside the opening and the lower end positioned outside the opening; and an installation step of moving the lower end of the exterior cladding suspended by the suspension member inward relative to the upper end, and installing the exterior cladding in the opening with the exterior cladding in an upright position.

[0010] According to the method for installing exterior materials according to claim 1, in the inclination process, the exterior material suspended by the suspension member of the suspension machine is inclined on the slab such that the lower end is located outward relative to the upper end, with the upper end positioned inside the opening and the lower end positioned outside the opening.

[0011] Thus, in this invention, by inclining the exterior material such that its lower end is located outward relative to its upper end, the upper end of the exterior material can be easily positioned inside the opening.

[0012] Next, during the installation process, the lower end of the exterior material, which is suspended by the suspension member, is moved inward relative to the upper end, and with the exterior material in an upright position, it is installed into the opening. This allows the exterior material to be installed into the opening.

[0013] Thus, in the present invention, exterior cladding can be installed on the outer perimeter of a structure, from the slab to an opening on the outside of the slab, with the upper end of the cladding positioned inside the opening.

[0014] The method for installing exterior materials according to claim 2 is the method for installing exterior materials according to claim 1, wherein in the tilting step, the exterior material is tilted by pushing it outward with a pushing member provided on the suspension machine, and in the installation step, the lower end of the exterior material is moved inward relative to the upper end by moving the pushing member inward.

[0015] According to the method for installing exterior materials according to claim 2, in the tilting step, the exterior material is tilted by pushing it outward with a pushing member provided on the suspension machine. Next, in the installation step, the lower end of the exterior material is moved inward relative to the upper end by moving the pushing member inward.

[0016] Thus, in this invention, labor can be reduced by tilting or raising the exterior material using a pushing member provided on the suspension machine.

[0017] The method for installing exterior materials according to claim 3 is the method for installing exterior materials according to claim 1 or claim 2, wherein in the installation step, the upper end of the exterior material is engaged with the opening from the inside.

[0018] According to the method for installing exterior materials according to claim 3, in the installation process, the upper end of the exterior material is engaged with the opening from the inside.

[0019] Thus, in this invention, the exterior material can be easily installed in the opening while the upper end of the exterior material is engaged with the opening from the inside. [Effects of the Invention]

[0020] As described above, according to the present invention, the upper end of the exterior material can be positioned inside the opening on the outer periphery of the structure.

Modes for Carrying Out the Invention

[0022] Hereinafter, an embodiment will be described with reference to the drawings.

[0023] (Structure) In FIG. 1, an exterior material 30 constructed by the exterior material construction method according to the present embodiment is shown. The exterior material 30 is, for example, a curtain wall, and is installed in an opening 20 outside (outdoor side) of the slab 14 on the slab 14 of a predetermined floor 10S of the structure 10.

[0024] The designated floor 10S of the structure 10 comprises upper and lower outer perimeter beams 12 and 13, and upper and lower slabs 14 and 16 supported by the upper and lower outer perimeter beams 12 and 13, respectively. The upper and lower outer perimeter beams 12 and 13 are, for example, steel beams formed from H-shaped steel, and are arranged along the outer perimeter of the structure 10. The upper and lower outer perimeter beams 12 and 13 are also erected on outer perimeter columns (not shown).

[0025] The upper and lower slabs 14 and 16 are made of reinforced concrete, and their outer perimeters are supported by the upper and lower outer perimeter beams 12 and 13, respectively. The lower slab (floor slab) 14 forms the floor of the designated floor 10S of the structure 10. On the other hand, the upper slab (ceiling slab) 16 forms the ceiling of the designated floor 10S of the structure 10. In other words, the upper slab 16 forms the floor of the floor above the designated floor 10S of the structure 10.

[0026] An opening 20 is provided on the outside of the slab 14 on a predetermined floor 10S of the structure 10. The opening 20 extends both above and below the slab 14 of the predetermined floor 10S. In other words, the opening 20 extends between the predetermined floor 10S of the structure 10 and the floor below that predetermined floor 10S. Furthermore, the opening 20 is formed between the upper and lower exterior wall materials 22 and 24.

[0027] The upper and lower exterior wall materials 22 and 24 are formed, for example, from concrete (precast concrete). The lower exterior wall material 22 is supported by the outer perimeter column (not shown) via brackets, etc. (not shown). Similarly, the upper exterior wall material 24 is supported by the outer perimeter column (not shown) via brackets, etc. (not shown). Exterior material 30 is installed to cover this opening 20.

[0028] Furthermore, the opening 20 may be demarcated not only by the exterior wall materials 22 and 24, but also by other members (exterior materials).

[0029] (Exterior materials) The exterior material 30 comprises a glass plate 32 and an outer frame 34 provided along the outer periphery of the glass plate 32. The outer frame 34 comprises upper and lower horizontal frame members 34A and left and right mullions 34B (vertical frame members). Note that the exterior material 30 is an example of a planar material.

[0030] As shown in Figure 2, fasteners 36 are provided at each corner on the inner surface of the outer frame 34. The fasteners 36 are made of, for example, angle steel. The exterior material 30 is attached to the outer periphery of the structure 10 by bolting these fasteners 36 to structural fasteners (not shown) provided on the outer periphery of the structure 10.

[0031] The structure, arrangement, and number of fasteners 36 can be changed as needed.

[0032] (Suspension device) Next, we will describe the lifting machine 40 used to transport the exterior material 30.

[0033] As shown in Figure 1, the suspension machine 40 is a self-propelled suspension transport machine (suspension transport trolley) that transports the exterior material 30 while suspending it. This suspension machine 40 is equipped with a trolley 42, a lifting lifter 50, a holding device 60, an operating device 48, and a tilt adjustment device 80.

[0034] (Cart) The bogie 42 comprises a bogie body 44, a plurality of wheels 46, and a driving device 48. The plurality of wheels 46 are rotatably mounted on the lower end of the bogie body 44 and are capable of traveling on a running surface 14U such as the upper surface of the slab 14. Of the plurality of wheels (four in this embodiment), at least two wheels 46 are drive wheels that are rotationally driven by a drive source (not shown), such as a motor, mounted on the bogie body 44.

[0035] The rear of the bogie body 44 is equipped with a driving device 48 that controls the stopping and starting of multiple wheels (drive wheels) 46, as well as steering these wheels 46. By operating this driving device 48, the bogie 42 can travel (become self-propelled) toward its destination.

[0036] Furthermore, the trolley 42 may be configured to be driven not only by a motor or other power source, but also by human power or other means.

[0037] (Lifting device) A lifting device 50 is mounted on the front of the trolley 42. The lifting device 50 has a lifting device 52 and a crane arm 54. The lifting device 52 has a configuration similar to that of a forklift, for example. This lifting device 52 has a hydraulic cylinder that extends and retracts in the vertical direction (the height direction of the lifting device 40) and supports the crane arm 54 so that it can be raised and lowered in the vertical direction.

[0038] The crane arm 54 is, for example, an attachment that is detachably mounted to the lifting device 52. The crane arm 54 also extends forward from the lifting device 52 to the suspension machine 40. This crane arm 54 is moved in parallel vertically by the lifting device 52.

[0039] The crane arm 54 may be attached to a lifting device such as a forklift. Furthermore, the crane arm 54 is not limited to an attachment that is detachably mounted to the lifting device 52, but may also be integrated with the lifting device 52.

[0040] The crane arm 54 has a horizontal arm section 54A, an inclined arm section 54B, and a lifting section 54C. The horizontal arm section 54A extends substantially horizontally from the lifting device 52 in front of the lifting machine 40. The inclined arm section 54B is provided at the tip of the horizontal arm section 54A. The inclined arm section 54B is inclined relative to the horizontal arm section 54A and extends diagonally upward (in front of and above the lifting machine 40) from the tip of the horizontal arm section 54A.

[0041] A suspension section 54C is provided at the tip of the inclined arm section 54B. A hook-shaped hook 56 is attached to the suspension section 54C. A holding device 60 is suspended from this hook 56 via a suspension member 58.

[0042] The inclined arm section 54B may be provided on the crane arm 54 as needed, and can be omitted as appropriate.

[0043] (hanging material) The suspension member 58 is a member that pivotably supports the exterior material 30, and is formed, for example, by a chain, wire, or carabiner. The upper end of the suspension member 58 is attached to a hook 56. On the other hand, a holding device 60 is attached to the lower end of the suspension member 58. The support portion of the suspension member 58 supported by the hook 56 is called the suspension point, which is the pivot point for the swinging of the suspension member 58.

[0044] (holding device) The holding device 60 is, for example, an adsorption device that uses suction (vacuum adsorption) to hold the glass plate 32 of the exterior material 30. As shown in Figure 2, the holding device 60 includes a mounting bracket 62 attached to the suspension member 58, a support base 64 supported by the mounting bracket 62, a rotating frame 66 rotatably supported by the support base 64, and a plurality of holding bodies 68 supported by the rotating frame 66 to hold the object to be held.

[0045] The upper end of the mounting bracket 62 is attached to the suspension member 58. A support base 64 is provided at the lower end of the mounting bracket 62. A rotating frame 66 is rotatably supported on the support base 64. This support base 64 is, for example, box-shaped and houses a drive source such as a motor that rotates the rotating frame 66.

[0046] Furthermore, the rotating frame 66 may be made rotatable not only by a motor or other drive source, but also by human power or other means.

[0047] The rotating frame 66 is rotatably supported on the support base 64 around a rotation axis R that extends in the front-rear direction (arrow X direction in Figure 1) of the holding device 60. This rotating frame 66 has a pair of main members 66A and a plurality of cross members 66B.

[0048] The pair of main members 66A extend in a predetermined direction and are arranged facing each other. Furthermore, the pair of main members 66A are arranged substantially parallel to each other. Brackets 70, described later, are provided at both ends of the pair of main members 66A.

[0049] The ends of the multiple cross members 66B extend outward from the pair of main members 66A. Retainers 68 are provided at each end of these cross members 66B. The retainers 68 are formed in a circular shape when the retaining device 60 is viewed from the front or rear direction.

[0050] As shown in Figure 1, the holder 68 has a holding surface 68G facing forward of the holding device 60. A vacuum pump (not shown) or the like, which sucks air from the holding surface 68G, is connected to the holder 68. With these holding surfaces 68G superimposed on the surface of the glass plate 32 of the exterior material 30, the glass plate 32 is held in place by suction to the holding surface 68G by operating the vacuum pump (not shown).

[0051] The holding device 60 may be equipped with at least one holding body 68. Furthermore, the holding device 60 may be powered by an electric power supply or by a battery. Also, the holding device 60 is not limited to a suction device; it may be any other holding device capable of holding the exterior material 30.

[0052] Here, brackets 70 are provided at both ends of the pair of main members 66A. Lever blocks (registered trademark) 72 are attached to both ends of each bracket 70.

[0053] The lever blocks 72 are attached to fasteners 36 provided at each corner of the exterior material 30. These lever blocks 72 support the exterior material 30 if the holding device 60 detaches from the exterior material 30. This prevents the exterior material 30 from falling.

[0054] The lever block 72 is just one example of a fall prevention member. Furthermore, the fall prevention member is not limited to the lever block 72; for example, a wire or rope may also be used.

[0055] (Tilt adjustment device) As shown in Figure 3, the tilt adjustment device 80 adjusts the tilt of the exterior material 30 suspended by the suspension member 58. The tilt adjustment device 80 is detachably attached to the suspension machine 40. The tilt adjustment device 80 comprises a pair of telescopic arms 82, a telescopic device 84 for extending and retracting the pair of telescopic arms 82, and rotating bodies 88 provided at the tips of the pair of telescopic arms 82. The telescopic arms 82 are an example of a pushing member.

[0056] The pair of telescopic arms 82 are detachably attached to the upper surface of the trolley body 44 of the trolley 42 by bolts or the like (not shown). In a plan view, the pair of telescopic arms 82 are positioned on both sides of the suspension device 40 in the width direction (arrow Y direction) relative to the suspension member 58 (see Figure 1). In other words, in a plan view, the pair of telescopic arms 82 are positioned on both sides of the suspension device 40 in the width direction relative to the lifting lifter 50.

[0057] A pair of telescopic arms 82 are arranged along the front-to-back direction (arrow X direction) of the suspension device 40. Each telescopic arm 82 has a sliding telescopic structure and is capable of moving (extending and retracting) in the front-to-back direction of the suspension device 40.

[0058] Specifically, the telescopic arm 82 has an outer cylinder 82A, a middle cylinder 82B, and an inner cylinder 82C, all with a rectangular cross-section. The outer cylinder 82A is fixed to the upper surface of the bogie body 44 of the bogie 42. The middle cylinder 82B is slidably inserted into the outer cylinder 82A in the axial direction. The inner cylinder 82C is also slidably inserted into the middle cylinder 82B in the axial direction.

[0059] The telescopic device 84 slides the middle cylinder 82B axially relative to the outer cylinder 82A, and slides the inner cylinder 82C axially relative to the middle cylinder 82B. The telescopic device 84 includes a wire (not shown) that slidably connects the outer cylinder 82A, the middle cylinder 82B, and the inner cylinder 82C, and a winding device 86 for winding the wire.

[0060] The winding mechanism 86 is located on the outer cylinder 82A. By rotating the operating handle 86A of the winding mechanism 86 in a predetermined direction, the wire is unwound from the winding mechanism 86 and the telescopic arm 82 is extended. Conversely, by rotating the operating handle 86A in the reverse direction, the wire is wound back onto the winding mechanism 86 and the telescopic arm 82 is retracted.

[0061] In this embodiment, the winding device 86 is manually operated, but the winding device 86 may also be electrically operated, for example, by a motor. Furthermore, the structure of the extension / retraction device 84 can be modified as appropriate.

[0062] A rotating body 88 is provided at the tip of the telescopic arm 82, that is, at the tip of the inner cylinder 82C, to protect the exterior material 30. The rotating body 88 is, for example, a rubber tire. The rotating body 88 is also rotatable around a rotation shaft 88A that extends in the width direction (arrow Y direction) of the suspension machine 40. By bringing the telescopic arm 82 into contact with the exterior material 30 via this rotating body 88, damage to the exterior material 30 is suppressed.

[0063] The rotating body 88 is not limited to a wheel such as a tire that rotates in one direction, but may also be, for example, a sphere that rotates 360 degrees. Furthermore, the tip of the telescopic arm 82 may be provided with a sliding material that slides on the inner surface of the exterior material 30, or a cushioning material, rather than just the rotating body 88. These rotating body 88, sliding material, and cushioning material can be provided on the telescopic arm 82 as needed and can be omitted as appropriate.

[0064] (Installation method for exterior materials) Next, an example of a method for installing the exterior material according to this embodiment will be described.

[0065] Figure 4 shows multiple exterior materials 30 that have been transported to a designated floor 10S of the structure 10 by a transport trolley 90. The multiple exterior materials 30 are loaded onto the transport trolley 90 on the slab 14 of the designated floor 10S in a horizontally upright position (hereinafter referred to as the "horizontally upright position").

[0066] More specifically, multiple exterior materials 30 are loaded onto a transport trolley 90 with their thickness direction (arrow X direction in Figure 1) and vertical direction (longitudinal direction) horizontal. The transport trolley 90 is transported to a predetermined floor 10S of the structure 10, for example, by an elevator or crane.

[0067] (Transportation process) From this state, first, in the transport process, the holding device 60 of the lifting machine 40 is brought close to the exterior material 30 loaded on the transport trolley 90, and the glass plate 32 of the exterior material 30 is held in place by the multiple holding bodies 68 of the holding device 60.

[0068] Furthermore, as shown in Figure 5, the two brackets 70 of the holding device 60 and the fasteners 36 at each corner of the exterior material 30 are connected by lever blocks 72. In this state, the crane arm 54 is raised by the lift device 52, and the exterior material 30 is lifted up in a horizontal upright position. Then, the lifting machine 40 is driven on the slab 14 to transport the exterior material 30 in a horizontal upright position to the vicinity of the opening 20 on the designated floor 10S.

[0069] The lever block 72 can be attached to the exterior material 30 as needed and can be omitted as appropriate.

[0070] (Rotation process) Next, as shown in Figure 6, during the rotation process, the rotating frame 66 is rotated around the rotation axis R relative to the support base 64 of the holding device 60 so that the upper end 30U side of the exterior material 30 faces upward, and the exterior material 30 is positioned facing the opening 20.

[0071] In this state, the exterior material 30 is tilted such that its lower end 30L is located inward (towards the interior) relative to its upper end 30U, depending on the positional relationship between the center of gravity of the exterior material 30 and the suspension point of the suspension member 58. In other words, the exterior material 30 is suspended by the suspension member 58 of the suspension device 40 in a forward-tilting position.

[0072] (tilt process) Next, as shown in Figure 7, in the tilting process, the pair of telescopic arms 82 of the tilt adjustment device 80 are extended, and the lower part of the exterior material 30 is pushed outward (outside the exterior) via the rotating body 88, thereby tilting the exterior material 30 so that the lower end 30L is located outside the upper end 30U. In other words, the exterior material 30 is tilted backward by pushing the lower part of the exterior material 30 outward with the pair of telescopic arms 82. Then, the upper end 30U of the exterior material 30 is positioned inside the opening 20, and the lower end 30L of the exterior material 30 is positioned outside the opening 20.

[0073] In this case, the extension length of the pair of telescopic arms 82 can be adjusted to rotate the exterior material 30 in the left-right direction around the suspension member 58, thereby adjusting the left-right orientation (tilt) of the exterior material 30.

[0074] (Installation process) Next, as shown in Figure 8, during the installation process, the pair of telescopic arms 82 are retracted, and the lower end 30L of the exterior material 30 is moved inward relative to the upper end 30U of the exterior material 30, while the crane arm 54 is lowered by the lift device 52, positioning the lower part of the exterior material 30 on the outside of the slab 14. At this time, the rotating body 88 provided at the tip of the pair of telescopic arms 82 travels upward on the inner surface of the exterior material 30.

[0075] Then, as shown in Figure 1, the exterior material 30 is raised, and the upper end portion 30U of the exterior material 30 is engaged with the opening 20 from the inside, while the lower end portion 30L of the exterior material 30 is positioned in the opening 20 from the outside. In this way, the exterior material 30 is installed in the opening 20.

[0076] (Installation process) Next, in the installation process, the lever block 72 is removed from the fastener 36 on the lower side of the exterior material 30. Then, the fastener 36 on the lower side of the exterior material 30 is bolted to a structural fastener (not shown) provided on the outer perimeter of the structure 10 (for example, the outer perimeter column).

[0077] Similarly, the lever block 72 is removed from the upper fastener 36 of the exterior material 30. Then, the upper fastener 36 of the exterior material 30 is bolted to a structural fastener (not shown) provided on the outer perimeter of the structure 10 (for example, the outer perimeter column). This attaches the exterior material 30 to the opening 20.

[0078] The mounting order of the upper and lower fasteners 36 of the exterior material 30 can be changed as appropriate.

[0079] (Removal process) Next, in the removal process, the telescopic device 84 is activated to retract the pair of telescopic arms 82. The holding device 60 is also activated to remove the multiple holding bodies 68 of the holding device 60 from the glass plate 32 of the exterior material 30.

[0080] The above construction procedure may be rearranged as appropriate depending on the size and shape of the exterior material 30 and the openings 20, and the arrangement of the openings 20, and unnecessary steps may be omitted as appropriate.

[0081] (effect) Next, the effects of this embodiment will be described.

[0082] (Installation method for exterior materials) First, let me explain the effectiveness of the exterior material installation method.

[0083] As shown in Figure 7, according to the method for installing exterior materials according to this embodiment, in the inclination process, the exterior material 30 suspended by the suspension member 58 of the suspension machine 40 is inclined on the slab 14 of a predetermined floor 10S of the structure 10 such that the lower end 30L is located outward relative to the upper end 30U, with the upper end 30U positioned inside the opening 20 and the lower end 30L positioned outside the opening 20.

[0084] In this embodiment, by inclining the exterior material 30 such that its lower end portion 30L is located outward relative to its upper end portion 30U, the upper end portion 30U of the exterior material 30 can be easily positioned inside the opening 20.

[0085] Next, in the installation process, the lower end 30L of the exterior material 30 suspended by the suspension member 58 is moved inward relative to the upper end 30U, and with the exterior material 30 in an upright position, the exterior material 30 is installed in the opening 20. This allows the exterior material 30 to be installed in the opening 20.

[0086] Thus, in this embodiment, the exterior material 30 can be installed on the outer periphery of the structure 10 from above the slab 14 into the opening 20 located outside the slab 14, and the upper end portion 30U of the exterior material 30 can be positioned inside the opening 20.

[0087] Furthermore, in this embodiment, during the tilting process, the exterior material 30 is tilted by pushing it outward with a pair of telescopic arms 82 provided on the suspension machine 40. Next, during the installation process, the lower end portion 30L of the exterior material 30 is moved inward relative to the upper end portion 30U by moving the pair of telescopic arms 82 inward.

[0088] Thus, in this embodiment, the exterior material 30 can be tilted or raised by a pair of telescopic arms 82 provided on the suspension device 40, thereby reducing the number of people required to operate it.

[0089] Furthermore, in this embodiment, during the installation process, the upper end portion 30U of the exterior material 30 is engaged with the opening 20 from the inside.

[0090] In this embodiment, by engaging the upper end portion 30U of the exterior material 30 with the opening 20 from the inside, the upper end portion 30U of the exterior material 30 can be easily positioned inside the opening 20.

[0091] Furthermore, in this embodiment, the opening 20 is located on the outside of the slab 14 of a predetermined floor 10S of the structure 10, and the height from the slab 14 to the upper exterior wall material 24 is lower than the height of the exterior cladding 30. This embodiment is particularly effective in such cases.

[0092] In other words, in this embodiment, as described above, during the inclination process, the exterior material 30 suspended by the suspension member 58 of the suspension machine 40 is inclined on the slab 14 so that the lower end 30L is located outward relative to the upper end 30U. By doing so, the exterior material 30 is lowered by the lift device 52 while the lower end 30L of the exterior material 30 is brought outward from the opening 20, thereby suppressing interference of the upper end 30U of the exterior material 30 with the upper exterior wall material 24, and allowing the exterior material 30 to be installed in the opening 20.

[0093] (Suspension device) Next, the effects of the suspension device 40 according to this embodiment will be described.

[0094] As shown in Figure 1, the suspension machine 40 according to this embodiment includes a suspension member 58 and a tilt adjustment device 80. The tilt adjustment device 80 adjusts the tilt of the exterior material 30 by pushing the exterior material 30, which is suspended by the suspension member 58, outward.

[0095] In this manner, the tilt of the exterior material 30, which is suspended by the suspension member 58, can be easily adjusted by pushing it outward with the tilt adjustment device 80. Therefore, in this embodiment, compared to, for example, a case where a worker pushes the exterior material 30 outward, the workload on the worker can be reduced, and manpower can be saved.

[0096] Furthermore, the tilt adjustment device 80 has a pair of telescopic arms 82 that are movable in the front-rear direction relative to the suspension machine 40. By moving this pair of telescopic arms 82 in the front-rear direction relative to the suspension machine 40, the tilt of the exterior material 30 can be easily fine-tuned.

[0097] Furthermore, the pair of telescopic arms 82 are extendable and retractable in the front-to-back direction of the suspension device 40. This reduces the installation space required for the pair of telescopic arms 82. Therefore, the suspension device 40 can be made more compact.

[0098] Furthermore, the tilt adjustment device 80 is detachably attached to the suspension machine 40. Therefore, the versatility of the tilt adjustment device 80 is improved.

[0099] Furthermore, the pair of telescopic arms 82 are positioned on both sides of the suspension member 58 in a plan view. By supporting the inner surface of the exterior material 30 at two points with these two telescopic arms 82, the exterior material 30 can be stabilized in a state where it is tilted at a predetermined angle.

[0100] Furthermore, a rotating body 88 is provided at the tip of each telescopic arm 82. By pushing the exterior material 30 outward via this rotating body 88 using the telescopic arm 82, damage to the exterior material 30 can be suppressed.

[0101] (modified version) Next, a modified example of the above embodiment will be described.

[0102] In the above embodiment, the tilt adjustment device 80 is equipped with a pair of telescopic arms 82. However, the tilt adjustment device 80 may be provided with at least one telescopic arm 82.

[0103] Furthermore, in the above embodiment, the pushing member is a telescopic arm 82. However, the pushing member is not limited to a telescopic arm 82; for example, it may be a sliding member that pushes the exterior material 30 by moving (sliding) in the front-rear direction of the suspension machine 40, or it may be a rotating arm that pushes the exterior material 30 by rotating around a rotation axis that extends in the height direction of the suspension machine 40.

[0104] Furthermore, in the above embodiment, the inclination of the exterior material 30 suspended by the suspension member 58 of the suspension machine 40 was adjusted by the inclination adjustment device 80. However, the inclination of the exterior material 30 is not limited to the inclination adjustment device 80; for example, it may be adjusted by the worker's hand.

[0105] Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments, and various modifications may be used in appropriate combinations with one embodiment, and it goes without saying that the invention can be implemented in various forms without departing from the spirit of the present invention.
