The horizontal direction in which the pillars 2A and 2B are separated from each other will be referred to as the "lateral direction" and the following description will be made. The column portions 2A and 2B are formed of, for example, columnar members, but the shape is not particularly limited. The height of the pillars 2A, 2B is at least higher than the height of the structure S provided on the rear side. At the upper ends of the pillars 2A and 2B, there are provided a small-diameter portion 11 extending vertically in a state in which the diameter is smaller than other portions, and a bent portion 12 extending laterally inward from the upper end of the small-diameter portion 11. (Particularly, see FIG. 5). At a corner between the small diameter portion 11 and the bent portion 12, a support portion 13 for supporting the pulley 14 is provided. The lower ends of the pillars 2A, 2B are connected to the moving bodies 3A, 3B, respectively.

  The moving bodies 3A and 3B support the pillars 2A and 2B at the lower ends, respectively, and are configured to be movable in a horizontal direction (horizontal direction). In the present embodiment, the moving bodies 3A and 3B are movable along the rails 110 provided on the installation surface SF (see FIG. 3). The moving bodies 3A and 3B include a lower frame 21 provided on the lower end side and an upper frame 22 provided above the lower frame 21. The upper frame 22 is formed in a rectangular ring shape so as to surround a position above the lower ends of the pillars 2A and 2B. Of the corners of the upper frame 22, support pillars 23 for fixing the second net 7 are erected at corners formed on the front side and laterally outward.

  As shown in FIGS. 4 and 6, the lower frame 21 is a rectangular ring-shaped member provided at the lower end of the pillars 2A, 2B. The lower frame 21 is connected to a pair of beam members 24, 24 extending in the lateral direction at positions facing the pair of rails 110, 110 at the upper side, and to the beam members 24, 24 extending in the front-rear direction at both ends in the lateral direction. And a pair of beam members 26, 26. A beam member (not shown) for fixing the lower ends of the columns 2A and 2B is provided inside the portion surrounded by the beam members 24, 24, 26 and 26. The lower frame 21 and the upper frame 22 are connected by connecting members 25, 25 extending in the up-down direction.

  The beam members 24 of the lower frame 21 are provided with a pair of moving parts 27, 27 guided by the rails 110, 110 and movable along the rails 110, 110 so as to be separated in the lateral direction. The moving units 27, 27 are constituted by, for example, chill rollers.

  The curing device 100 includes a fixing member 30 for fixing the moving bodies 3A and 3B to the installation surface SF side. The fixing member 30 is provided on the beam members 24, 24 of the lower frame 21. Specifically, the fixing member 30 includes a push-up portion 31 for separating the lower frame 21 from the rail 110, a first connecting portion 32 for connecting the lower frame 21 to the upper flange portion 110 a of the rail 110, and a lower frame 21.

The leg portion 31c moves downward as the bolt 31b is screwed into the nut 31d welded to the mounting portion 31a, and contacts the upper surface of the upper flange portion 110a of the rail 110. When the bolt 31b is further screwed into the nut 31d of the mounting portion 31a while the leg portion 31c is in contact with the upper flange portion 110a, the entire beam member 24 is separated upward from the rail 110 via the mounting portion 31a. As a result, the moving part 27 floats from the upper flange part 110a of the rail 110, so that the moving bodies 3A and 3B cannot move with respect to the rail 110, and the moving bodies 3A and 3B are substantially fixed to the installation surface SF side. It will be in the state that was done.

  As shown in FIGS. 4 and 7B, the first connecting portion 32 is attached to the mounting plate 32 a protruding in the front-rear direction from the beam member 24 of the lower frame 21, and is connected to the rail 110. A possible L-shaped fitting 32b. The mounting plate 32a is a plate-shaped member that expands in the vertical direction, and protrudes to both sides in the front-rear direction of the beam member 24. The L-shaped fitting 32b is joined to the mounting plate 32a and extends downward to a position reaching the rail 110. The L-shaped bracket 32b has a bent portion 32c which bends at a lower end and turns around to a position facing the lower surface of the upper flange portion 110a of the rail 110. The bent portion 32c is separated from the lower surface of the upper flange portion 110a of the rail 110 before the push-up portion 31 raises the moving portion 27 from the rail 110. However, in a state where the push-up portion 31 lifts the moving portion 27 from the rail 110 and separates the moving portion 27 upward by a certain amount, the bent portion 32c contacts the lower surface of the upper flange portion 110a of the rail 110. Thereby, the first connecting portion 32 is connected to the rail 110, and the moving bodies 3A and 3B are fixed to the installation surface SF side.

  As shown in FIGS. 4 and 7C, the second connecting portion 33 includes a connecting member 33 a provided on the upper surface of the beam member 24 of the lower frame 21 and extending in the front-rear direction, and a lower flange of the rail 110. The connecting member 33b is provided on the lower surface side of the portion 110b and extends in the front-rear direction. The connecting member 33b extends in the vertical direction and connects the connecting members 33a and 33b. The connecting member 33a projects in the front-rear direction from the beam member 24, and the connecting member 33b projects in the front-rear direction from the rail 110. The hairpin bolt 33c is connected to the front and rear portions of the connecting members 33a and 33b. The connection member 33b is separated from the lower surface of the flange 110b on the lower side of the rail 110 in a state before the push-up portion 31 raises the moving portion 27 from the rail 110. However, in a state where the push-up portion 31 lifts the moving portion 27 from the rail 110 and separates the moving portion 27 upward by a certain amount, the connecting member 33b contacts the lower surface of the lower flange portion 110b of the rail 110. Thereby, the second connecting portion 33 is connected to the rail 110, and the moving bodies 3A and 3B are fixed to the installation surface SF side.

  As shown in FIG. 2, the first net 6 is a net-like member that extends between the pillars 2A and 2B and that extends in the vertical direction. The lateral size of the first net 6 (that is, the distance between the lateral edges 6c, 6c) is larger than the lateral size of the structure S. The upper edge portion 6a of the first net 6 is arranged at a position higher than the structure S even in consideration of the deflection near the center position in the horizontal direction (in a state of being arranged at the highest position). The lower edge 6 b of the first net 6 is fixed to the connecting member 4.

  The second net 7 is a net-like member provided below the first net 6 and spanned between the pair of moving bodies 3A and 3B and spread in the up-down direction. The lateral edges of the second net 7 are fixed to support columns 23 of the moving bodies 3A and 3B. The upper edge 7a of the second net 7 is set at the height of the upper end of the support column 23. A portion near the upper edge 7a of the second net 7 overlaps a portion near the lower edge 6b of the first net 6. The lower edge 7b of the second net 7 is disposed below the lower edge 6b of the first net 6. The lower edge 7b of the second net 7 extends to a position reaching the lower end of the rail 110.

  Next, with reference to FIGS. 2, 4, and 5, a configuration of the lifting mechanism 8 that raises and lowers the first net 6 will be described. As shown in FIG. 2, the lifting mechanism 8 includes a rope 41 that supports the upper edge 6 a of the first net 6, the rope 41 that is supported on the columns 2 </ b> A, 2 </ b> B, and along the columns 2 </ b> A, 2 </ b> B. The length adjusting ropes 42, 42 extending in the vertical direction, the length adjusting ropes 43, 43 for adjusting the length of the length adjusting ropes 42, 42, and the lateral edges 6c, 6c of the first net 6 are supported. And a guide rope 44 for guiding the upper edge 6a of the first net 6 up and down.

  As shown in FIG. 2 and FIG. 5, the rope 41 extends in the lateral direction between the pillars 2A and 2B. The rope 41 supports the upper edge 6a of the first net 6 via a carabiner 46 provided on the upper edge 6a of the first net 6 at regular intervals. Both ends of the rope 41 in the lateral direction are connected to the length adjusting rope 42 via a turnbuckle 47 and a shackle 48, respectively (see especially FIG. 5).

  As shown in FIG. 5, the length adjusting rope 42 extends laterally outward from the shackle 48 (the portion is referred to as a portion 42A) and is supported by the pulley 14 supported by the support portion 13 of the column 2A (2B). It is supported and extends downward. As shown in FIG. 4, the lower end of the length adjusting rope 42 is connected to the length adjusting unit 43. The length adjustment unit 43 is configured by, for example, a winch that winds and unwinds the length adjustment rope 42. The winch may be driven manually by an operator or may be driven by a motor or the like. When the length adjusting section 43 rewinds the length adjusting rope 42, the length adjusting rope 42 is extended, and the length of the portion 42A is increased. When the length adjusting section 43 winds up the length adjusting rope 42, the length adjusting rope 42 is wound up, and the length of the portion 42A is shortened.

  As shown in FIGS. 2, 4 and 5, the guide rope 44 extends vertically between the upper ends of the pillars 2A and 2B and the moving bodies 3A and 3B. The guide rope 44 supports the lateral edge 6c of the first net 6 via a carabiner 51 provided on the lateral edge 6c of the first net 6 at regular intervals. The upper end of the guide rope 44 is connected to the tip of the bent portion 12 via a shackle 52 (see particularly FIG. 5). The lower end of the guide rope 44 is connected to the upper frame 22 via a turnbuckle 53 (see particularly FIG. 4). The guide rope 44 is inserted into a shackle 48 that connects the length adjustment unit 43 and the rope 41.

  The lifting operation of the first net 6 by the lifting mechanism 8 will be described. First, the state in which the rope 41 is shown by a solid line in FIG. 2 is a state in which the upper edge 6a of the first net 6 is arranged at the highest position. In this state, when the length adjusting rope 42 is rewound by the length adjusting unit 43, the length adjusting rope 42 is extended. Here, the guide rope 44 is inserted through a shackle 48 that connects the length adjustment unit 43 and the rope 41. The positions of both ends of the rope 41 in the lateral direction are substantially constant at the connecting portion of the shackle 48 and the guide rope 44. Therefore, when the length adjustment rope 42 is extended, the deflection of the rope 41 does not change, and the state in which the tension is kept substantially constant is maintained. On the other hand, the length 42A of the length adjustment rope 42 becomes longer. That is, the shackle 48 moves downward while being guided by the guide rope 44, and the carabiner 51 also moves downward while being guided by the guide rope 44. As a result, the rope 41 and the upper edge 6a of the first net 6 move downward while the tension is kept substantially constant (see the two-dot chain line MP shown in FIG. 2). The lateral edge 6c of the first net 6 can also move downward in a stable state while being guided by the guide ropes 44.

  On the other hand, when the length adjusting rope 43 is wound around the length adjusting rope 42, the deflection of the rope 41 does not change, but the length 42A of the length adjusting rope 42 becomes shorter. That is, the shackle 48 moves upward by being guided by the guide rope 44, and the carabiner 51 also moves upward by being guided by the guide rope 44. Thereby, the rope 41 and the upper edge 6a of the first net 6 move upward while the tension is kept substantially constant. The lateral edge 6c of the first net 6 can also move upward in a stable state while being guided by the guide rope 44.

  Next, the operation and effect of the curing device 100 according to the present embodiment will be described.

  The curing device 100 according to the present embodiment includes the pillars 2A and 2B extending in the vertical direction and separated from each other in the horizontal direction, and the first net 6 bridged between the pillars 2A and 2B and extending in the vertical direction. Have. Therefore, by setting the pillar portions 2A and 2B at a place where curing is to be performed, the first net 6 can cure the place. Here, the curing device 100 includes an elevating mechanism 8 that moves the upper edge 6a of the first net 6 up and down. Therefore, when the operation is completed or when the wind is strong, the upper edge portion 6a of the first net 6 can be lowered using the lifting mechanism 8 and the curing can be easily removed. When necessary, the first net 6 can be removed using the lifting mechanism. The upper edge can be raised for easy curing. In addition, the curing device 100 includes moving bodies 3A and 3B that support the pillars 2A and 2B at the lower ends, respectively, and that can move in the horizontal direction. Therefore, when the work at the predetermined work place is completed, the moving bodies 3A and 3B move in the horizontal direction, so that curing can be easily performed at different work places. As described above, curing and removal can be easily performed at a necessary place and timing.

  For example, as shown in FIG. 1, when the vibration control devices are provided in the sections A to F, the following curing can be performed using the curing device 100. For example, when the installation work is performed in the section A, the curing device 100 is arranged in front of the section A (position PA). When the installation work is performed in the section B, the curing device 100 is arranged in front of the section B. When the installation work is performed in the section C, the curing device 100 is arranged on the near side (position PB) of the section C, and the curing device 100 is arranged on the side (position PC) of the section C. When the installation work is performed in the section D, the curing device 100 is arranged on the near side (position PE) of the section D, and the curing device 100 is arranged on the side (position PD) of the section D. When the installation work is performed in the section E, the curing device 100 is arranged in front of the section E. When the installation work is performed in the section F, the curing device 100 is arranged on the near side (position PF) of the section F.

  In the example as shown in FIG. 1, when one curing device 100 is installed on the upper side (the upper side of the paper surface in FIG. 1) of the rail 110 installed in a rectangular shape, the movement of the moving bodies 3A and 3B is performed. When the installation work of the section A is completed, the section B is cured by moving to the section B, and when the installation work of the section B is completed, the section C is cured by moving to the section C. . When one curing device 100 is installed on the lower side of the rail 110 (the lower side of the paper surface in FIG. 1), the moving of the moving bodies 3A and 3B causes the section E to be set when the installation work of the section D is completed. Then, the section E is cured by moving to the section. After the installation work of the section E is completed, the section F is cured by moving to the section F. When one curing device 100 is used on the left and right sides of the rail 110 (the left and right sides in FIG. 1), when the installation work in the section C is completed and the installation work in the section D is performed, the position PC The disposed curing device 100 is dismantled, and the curing device 100 is installed at the position PD.

  In the curing device 100 according to the present embodiment, the moving bodies 3A and 3B can move along the rail 110 provided on the installation surface SF. According to such a configuration, the moving bodies 3A and 3B can easily move along the rail 110 with a simple configuration.

  In the curing device 100 according to the present embodiment, the elevating mechanism 8 supports the lateral edge 6c of the first net 6 and guides the guide rope 44 that guides the elevation of the upper edge 6a of the first net 6. Have. Since the elevating mechanism 8 includes the guide rope 44, the elevating mechanism 8 can perform elevating and lowering with the tension at the lateral edge 6c and the upper edge 6a of the first net 6 being stabilized. For example, in a case where the tension acting on the upper edge portion 6a is reduced as the upper edge portion 6a is lowered and the upper edge portion 6a is bent, unnecessary force is exerted by the first net 6 fluttering when wind blows. Resulting in. On the other hand, when the tension at the lateral edge 6c and the upper edge 6a is stable regardless of the elevating state, it is possible to prevent the wind from flying.

  In addition, the curing device 100 according to the present embodiment includes a second net 7 provided below the first net 6 and bridged between the pair of moving bodies 3A and 3B. Since the curing device 100 includes the second net 7, falling objects falling from below the first net 6 can be more reliably prevented.

  In addition, the curing device 100 according to the present embodiment includes a fixing member 30 that fixes the moving bodies 3A and 3B to the installation surface SF side. Thereby, safety can be improved by fixing the moving bodies 3A and 3B to the installation surface SF side by the fixing member 30 during the work.

  The present invention is not limited to the above embodiment. For example, the shapes and the like of the pillars and the moving body are merely examples, and may be changed as appropriate.

  In addition, the moving body does not have to move along the rail, and may have, for example, a wheel and a motor that can travel on the installation surface SF. In addition, the rail may be newly installed on the installation surface SF at the time of construction. Alternatively, the rails need not be newly installed. For example, the rail may use a gondola rail used for maintenance (window cleaning, painting, etc.) of a high-rise building. Thus, it is not necessary to newly install a rail for moving the moving body, and the existing gondola rail can be used.

  Further, the lifting mechanism is not limited to the above-described configuration. For example, the guide rope may not be provided, and the upper edge of the first net may be lowered while bending the length adjusting rope.
