For this reason, the attachment base 40 is set on the fork 61 in a stable state while preventing it from falling off. Can do. Further, the withdrawal prevention means 64 includes a bolt 65 and a nut 66 that are separable from the cylindrical member 44, and therefore, by separating the bolt 65 and the nut 66 from the cylindrical member 44, the attachment base 40 is moved to the fork 61. It is also possible to remove from.

  In FIG. 13, after the fork 61 of the forklift vehicle 60 on which the attachment base 40 is set as described above is slightly raised, the forklift vehicle 60 is caused to travel forward toward the transport carriage 20, or FIG. 4, the operator advances the transport cart 20 with the handle member 33 shown in FIG. 4 toward the attachment table 40 by the handle member 33, so that the two left and right cylindrical members 44 of the attachment table 40 are moved to the transport cart. 20 shows a state in which the take-up shaft 4 is placed on the lower side of the take-up shaft 4 placed on the first placement member 31. This is performed until the position of the pair of first mounting members 31 provided matches the position of the pair of third mounting members 57 provided on the attachment base 40. 14 is a cross-sectional view taken along line S14-S14 in FIG. As described above, since the dimension L1 in FIG. 7 is smaller than the dimension L2 in FIG. 4, the above-described insertion operation is performed as two cylindrical members provided on the attachment base 40 as shown in FIG. 44 can be carried out by entering between the two base members 21 provided on the left and right of the transport carriage 20.

  7 is smaller than the dimensions H2 and H3 in FIG. 4, the third mounting member 57 provided on the attachment base 40 is attached to the transport carriage 20 as shown in FIG. 14. Below the lower end 4B of the take-up shaft 4 placed on the first placement member 31 provided, above the connecting member 24 that connects the two base members 21 of the transport carriage 20 In this case, the insertion operation described above can be performed. Further, as shown in FIG. 14, the first mounting is provided on each of the two base members 21 of the transport carriage 20, and two are placed apart in the axial direction of the winding shaft 4. The interval between the members 31 is provided on each of the two cylindrical members 44 of the attachment base 40, and is larger than the interval between the third placement members 57 that are disposed two apart in the axial direction of the winding shaft 4. Since it is large, the above-described insertion operation can be performed by allowing the two third placement members 57 of the attachment base 40 to enter between the two first placement members 31 of the transport carriage 20.

  FIG. 15 shows a state where the attachment base 40 is lifted by the fork 61 by raising the fork 61 of the forklift vehicle 60 after performing the above-described insertion operation. By this lifting operation, the take-up shaft 4 placed on the first placement member 31 of the transport carriage 20 is transferred to the third placement member 57 of the attachment base 40. For this reason, in this embodiment, the conveyance cart 20 is a delivery table for delivering the winding shaft 4 to the attachment table 40, and the attachment table 40 is for receiving the winding shaft 4 from the conveyance vehicle 20. It is a receiving stand.

  Then, a fork 61 for raising the attachment base 40 to deliver the winding shaft 4 placed on the first placement member 31 of the transport carriage 20 to the third placement member 57 of the attachment base 40. The forklift vehicle 60 provided with is a lift device in the present embodiment.

  After performing the above operations, the forklift vehicle 60 is traveled to the installation site of the shutter device, and the fork 61 is further lifted as shown in FIG. 16 to be placed on the third placement member 57. Thus, the winding shaft 4 placed on the attachment base 40 is lower than the height position of the bracket 3 arranged on the left and right two on the housing 8 which is the stationary member of the building shown in FIG. Lift up. In FIG. 16, the forklift vehicle 60 is indicated by a two-dot chain line.

  Then, until the take-up shaft 4 placed on the attachment base 40 is lifted to a position lower than the height position of the two brackets 3, the forklift vehicle 60 is omitted in FIG. As shown in FIG. 17 which is a side view and FIG. 18 which is a rear view of FIG. 16, the third mounting member 57 is formed by three wires 51 provided on the left and right sides of the attachment base 40. The take-up shaft 4 placed on is suspended and supported. In the present embodiment, this suspension support is performed by placing the lower part of each wire 51 extending downward from the front pulley 47 out of the two pulleys 47, 48 provided on the front and rear of the attachment base 40. The hook member 52 attached to the lower end of the wire 51 is engaged with the wire 51 on the upper side of the winding shaft 4. Such work is performed from the state shown in FIG. 13 by the lift of the fork 61 of the forklift vehicle 60 so that the winding shaft 4 is received by the third mounting member 57 of the attachment base 40 from the first mounting member 31 of the transport carriage 20. Immediately after being handed over, it can be performed by stopping the fork 61 from rising, so that the worker can perform this work at a low position without using a lifting tool such as a ladder or a stepladder.

  Next, by operating the transmitter described above, the operator rotates the take-up reel 54 provided for each wire 51 by driving the drive device 55 provided for each wire 51. The winding shaft 4 is lifted and supported by the wire 51 from the third placement member 57 by winding the wire 51 with these winding reels 54. Then, as shown in FIGS. 19 to 21, two height positions of the lifting support of the winding shaft 4 are provided on the housing 8 which is a stationary member of the building for receiving the winding shaft 4. After setting to the same height position as the bracket 3 provided or substantially the same height position, the forward rotation of each take-up reel 54 is stopped by operating the transmitter. Thereafter, the forklift vehicle 60 is moved forward, or the operator pushes the winding shaft 4 supported by being suspended by the wire 51, so that the above-described axial ends of the winding shaft 4 are provided. 4A are inserted into the recesses 3A formed in the respective brackets 3 so that both ends in the axial direction of the winding shaft 4 are spaced apart from each other in the axial direction of the winding shaft 4. It is received by two brackets 3 arranged.

  Next, an operation of fixing the bearing members 12 arranged on the respective neck portions 4 </ b> A to the respective brackets 3 with screws or the like is performed, whereby the winding shaft 4 is rotatably supported by the two brackets 3. .

  In order to rotatably support the take-up shaft 4 by the two brackets 3, two neck portions 4 </ b> A provided at both end portions in the axial direction of the take-up shaft 4 are formed in the recesses of the two brackets 3. 3A is required to be accurately inserted. For this reason, the lifting support of the winding shaft 4 by the wire 51 is used so that the height position of each neck 4A coincides with the height position of the recess 3A of each bracket 3 or substantially. It is necessary to do this until they match. For this reason, in the present embodiment, of the three wires 51, the two wires 51 arranged on the left and right sides lift and support two places separated in the axial direction of the winding shaft 4. These wires 51 can be moved up and down individually by rotating the respective winding reels 54 forward and backward individually by the operation of the transmitter described above. By performing the work of raising and lowering the two neck portions 4A of the take-up shaft 4 individually, even if the take-up shaft 4 is bent and deformed downward by its own weight or the like, the height positions of the respective neck portions 4A of the take-up shaft 4 The height positions of the recesses 3A of the respective brackets 3 can be exactly matched or substantially matched.

  In the above description, the winding shaft 4 is lifted and supported by the three wires 51 provided on the attachment base 40 in the left-right direction. However, the lifting support is performed only by the two wires 51 on the left and right sides. You may go.

  In the present embodiment described above, the two brackets 3 are arranged on the take-up shaft 4 delivered from the first placement member 31 of the transport carriage 20 to the third placement member 57 of the attachment base 40. The work of lifting to a high place of the building is a first lifting for lifting the take-up shaft 4 placed on the attachment base 40 to a position lower than the place where the bracket 3 is arranged by raising the fork 61 of the forklift vehicle 60. This includes a work process and a second lifting work process for lifting the take-up shaft 4 to the place where the bracket 3 is disposed by a wire 51 disposed on the attachment base 40.

  Moreover, in this embodiment, since the above-mentioned 1st lifting work process is performed by the raising of the fork 61 of the forklift vehicle 60 in which the attachment base 40 is set, this fork 61 performs the 1st lifting work process. Further, the wire 51 disposed on the attachment base 40 suspends and supports the winding shaft 4 by suspending the winding shaft 4 to the height where the two brackets 3 are disposed. Therefore, the attachment base 40 is provided with the wire 51, a winding reel 54 for winding and feeding the wire 51, a driving device 55 for rotating the winding reel 54 forward and backward, and the like. The second lifting means for carrying out the second lifting work step is configured. The wire 51 constitutes a part of the second lifting means, and serves as a support member for lifting and supporting the winding shaft 4 and also serves as a string-like member.

  In the above embodiment, since the above-mentioned first lifting work process is a work for raising the fork 61 of the forklift vehicle 60, the second lifting work process carried out by winding the wire 51 with the take-up reel 54. However, the work can be performed at a higher speed than the second lifting work process. In addition, the second lifting work process is performed at a lower speed than the first lifting work process, but is more accurate than the first lifting work process by controlling the vertical movement amount of the wire 51 by the take-up reel 54. It is work that can be carried out in. For this reason, according to this embodiment, the operation of lifting the take-up shaft 4 whose place of placement is a high place of the structure can be performed quickly and with high accuracy, and this operation can be facilitated.

  In addition, the wire 51 disposed on the attachment base 40 as a support member or a string-like member as described above supports at least two places separated in the axial direction of the winding shaft 4 in this embodiment. Since these wires 51 can be moved up and down individually, the winding shafts can be moved up and down individually at these two locations in the axial direction of the winding shaft 4 as described above. Even if 4 is curved and deformed downward due to its own weight or the like, the height positions of the neck portions 4A provided at both ends in the axial direction of the take-up shaft 4 can be individually adjusted. The operation of making the height position of 4A coincide with or substantially coincide with the height position of the recess 3A of each bracket 3 can be performed more accurately and easily.

  Next, an operation for connecting the upper end of the shutter curtain 1 to the winding shaft 4 received by the two brackets 3 as described above will be described.

  FIG. 22 shows an initial operation for transferring the shutter curtain 1 from the second mounting member 32 of the transport carriage 20 to the fourth mounting member 58 of the attachment base 40 in order to perform this operation. Yes. In this operation, the cylindrical member 44 of the attachment base 40 set on the fork 61 of the forklift vehicle 60 is applied to the second mounting member 32 of the transport carriage 20 in the same manner as the winding shaft 4 shown in FIG. It is an operation of inserting the shutter curtain 1 below the shutter curtain 1 that is wound in a spiral shape, and this insertion operation includes the position of the pair of second mounting members 32 provided on the transport carriage 20 and the attachment. This is performed until the positions of the pair of fourth mounting members 58 provided on the table 40 match.

  At this time, since the dimension H1 in FIG. 7 is smaller than the dimension H3 in FIG. 4 as described above, the lower side 1D of the shutter curtain 1 placed on the second placement member 32 of the transport carriage 20 is below. In addition, the above-described insertion operation can be performed by allowing the cylindrical member 44 of the attachment base 40 to enter above the connecting member 24 that connects the two base members 21 of the transport carriage 20.

  Next, as shown in FIG. 23, the fork 61 of the forklift vehicle 60 is lifted to lift the attachment base 40 with the fork 61, thereby placing it on the second placement member 32 of the transport carriage 20. An operation for transferring the shutter curtain 1 that has been performed to the fourth placement member 58 of the attachment base 40 is performed. Thereafter, the forklift vehicle 60 is caused to travel to the installation site of the shutter device, and the fork 61 is raised, so that the forklift vehicle 60 is spirally wound around the fourth mounting member 58 of the attachment base 40 as can be seen from FIG. The attachment table 40 is raised to a position where the height position of the shutter curtain 1 placed in this manner is lower than the height position of the winding shaft 4 received by the two brackets 3.

  Next, the worker performs an operation of hooking the hook member 52 provided at the tip of the wire 51 on the upper end of the shutter curtain 1. 25, the hook member 52 is inserted into the hole 68 of the suspension member 1B provided at the upper end of the shutter curtain 1 in order to connect the upper end of the shutter curtain 1 to the winding shaft 4. The hole 68 is a bolt hole into which a bolt for coupling the suspension member 1B of the shutter curtain 1 to the winding shaft 4 is inserted. A plurality of suspension members 1B are provided in the left-right direction, which is the axial direction of the shutter curtain 1 wound in a spiral shape, and each suspension member 1B has a height at the suspension member 1B. A plurality of holes 68 having different positions are formed apart in the left-right direction. Thereby, when the shutter curtain 1 is wound up by the winding shaft 4, the hole 68 that can be wound up by the winding shaft 4 without the lateral displacement of the shutter curtain 1 is selected and the bolt is inserted, and the suspension member 1B can be coupled to the winding shaft 4.

  In the present embodiment, among the suspension members 1B of FIG. 25 provided in the left-right direction, three are provided in the left and right directions on the attachment base 40 in the holes 68 of the suspension member 1B in the central portion in the left-right direction. Among the wires 51, the hook member 52 of the wire 51 at the center in the left-right direction is inserted, and a plurality of the hook members 52 are formed in the left-right direction in the suspension member 1B at the center in the left-right direction. Of these, it is inserted into the hole 68 at the center in the left-right direction. Thus, as will be described later, when the upper end of the shutter curtain 1 is pulled up by pulling up one wire 51 in the central portion in the left-right direction, the entire upper end can be pulled up uniformly.

  After performing the above operation, the operator operates the transmitter described above, and among the three wires 51 provided in the left-right direction, only one wire 51 in the central portion in the left-right direction is connected to this wire. 51, the take-up reel 54 disposed on the attachment base 40 is rotated forward by the drive device 55, so that as shown in FIG. 24 and FIG. The upper end of the shutter curtain 1 is pulled up by the wire 51 and the height position of the upper end is the same as or substantially the same as the height position of the winding shaft 4 supported by the two brackets 3. To do. Next, the operator pulls out the hook member 52 from the hole 68, and couples each suspension base member 1B to the take-up shaft 4 with the above-described bolt as shown in FIG.

  Next, the operator rotates the winding shaft 4 rotatably supported by the two brackets 3, thereby rotating the shutter wound spirally around the fourth placement member 58 of the attachment base 40. In order to form the shutter curtain 1 from the curtain 1, the respective slats 1 </ b> C connected under the suspension base member 1 </ b> B are fed out, and the slats 1 </ b> C are wound up by the winding shaft 4. The state when performing this operation is shown in FIG. At this time, the shutter curtain 1 wound in a spiral shape rotates on the fourth mounting member 58, but the fourth mounting member 58 is a rotatable rotating member as described above. Therefore, the shutter curtain 1 can be smoothly rotated on the fourth placement member 58, whereby the operation of winding the respective slats 1 </ b> C with the winding shaft 4 can be performed more reliably.

  By this time, when the operation of attaching the switch 5 and the driving force transmission device 6 shown in FIG. 1 for rotating the winding shaft 4 to one of the two brackets 3 has been completed. The operation of rotating the take-up shaft 4 in order to take up each slat 1C of the shutter curtain with the take-up shaft 4 may be performed using the opening / closing device 5 and the driving force transmission device 6.

  After the operation of winding the entire shutter curtain 1 with the winding shaft 4 is completed, the remaining work such as the operation of attaching the left and right guide rails 2 shown in FIG. 1 to the housing 7 and the operation of attaching the shutter case 9 to the housing 8 are performed. Do work. Next, the winding shaft 4 is reversely rotated by the opening / closing machine 5, the driving force transmission device 6 and the like, whereby both ends in the width direction of the shutter curtain 1 fed out from the winding shaft 4 are placed inside the left and right guide rails 2. The shutter curtain 1 is lowered. When this operation is completed, the shutter device is in a state where the shutter curtain 1 can open and close the doorway 10 of FIG.

  In the above embodiment, the wire 51 at the center in the left-right direction is a string-like member suspended from above the shutter curtain 1 placed on the fourth placement member 58 of the attachment base 40 and the shutter. It is also a raising member for raising the upper end of the curtain 1. And the attachment stand 40 in which the wire 51 used as a raising member is arrange | positioned in this way is also the raising apparatus in this embodiment.

  According to the present embodiment described above, the shutter curtain 1 whose upper end is coupled to the winding shaft 4 rotatably received by the two brackets 3 opens and closes all or substantially all of the entrance / exit 10 in advance in the factory. Therefore, after the suspension member 1B is coupled to the winding shaft 4 with a bolt at the installation site of the shutter device, the shutter curtain 1 having such a size is mounted. An operation for winding by the winding shaft 4 can be performed.

  In other words, the shutter curtain 1 according to the present embodiment is formed in advance in a factory so as to be able to open and close all or substantially all of the entrance / exit 10, so that the shutter curtain is installed at the installation site of the shutter device. When the suspension member 1B provided at the upper end of 1 is coupled to the winding shaft 4 with a bolt, the shutter curtain 1 is coupled to the winding shaft 4 and can be wound around the winding shaft 4. Can be easily formed in a short time at the installation site of the shutter device.

  For this reason, according to the present embodiment, for the shutter curtain 1 which is mostly formed by connecting a large number of slats 1C, the suspension member 1B is coupled to the winding shaft 4 with bolts at the installation site of the shutter device. Later, in order to form the shutter curtain 1 by connecting the respective slats 1C with the curled portions formed at the upper and lower ends of the slats 1C so as to be rotatable, these slats 1C are formed. The operation of sequentially sliding 1C from the lateral direction can be omitted, and therefore, the operation of forming the shutter curtain 1 wound around the winding shaft 4 can be easily performed at the installation site of the shutter device.

  Further, according to the present embodiment, the wire 51 serving as the string-like member and the lifting member described above is inserted into the hole 68 of the suspension member 1 </ b> B provided at the upper end of the shutter curtain 1. Since the hook member 52 for hooking and lifting the upper end of the shutter curtain 1 is provided, the operation of pulling up the upper end of the shutter curtain 1 to connect the upper end of the shutter curtain 1 to the winding shaft 4 is performed on the winding shaft 4. In order to connect the upper end of the curtain 1, it can carry out using the suspension member 1B provided in this upper end. Moreover, since the hole 68 for hooking the hook member 52 is a bolt hole for inserting a bolt for connecting the lifting member 1B to the take-up shaft 4, the shutter 51 is pulled up by the wire 51 using this bolt hole. Work can be done.

  Furthermore, in this embodiment, before performing the operation | work which pulls up the upper end of the shutter curtain 1 with the hook member 52 of the wire 51, the shutter mounted in the attachment base 40 and the 4th mounting member 58 of this attachment base 40. The curtain 1 is lifted at a high speed to a position slightly lower than the height position of the take-up shaft 4 received by the two brackets 3 by the fork 61 of the forklift vehicle 60 serving as the lift device described above. Therefore, the upper end of the shutter curtain 1 is the same as or substantially the same as the height position of the winding shaft 4 by the wire 51 provided as a lifting member on the attachment base 40 serving as the lifting device described above. The work to raise to the same height position can be performed in a short time. To shorten the entire working time to bind the edge the winding shaft 4, thereby improving the working efficiency.

  Further, in the present embodiment, the fork 61 of the forklift vehicle 60 includes the attachment base 40 and the shutter curtain 1 wound and placed on the fourth placement member 58 of the attachment base 40 in a spiral shape. After being lifted at a high speed to a position slightly lower than the height position of the winding shaft 4 received by the single bracket 3, the hook member 52 of the wire 51 is hooked in the hole 68 of the suspension member 1B, and the shutter curtain. The lifting of the upper end of the shutter curtain 1 is performed while unwinding the shutter curtain 1 that is wound around the attachment base 40 in a spiral manner, so that the lifting operation of the upper end of the shutter curtain 1 can be performed smoothly. .

  Further, since the shutter curtain 1 arranged in a spiral shape on the attachment base 40 is placed on the fourth placement member 58 provided to be rotatable on the attachment base 40, When the upper end of the shutter curtain 1 is lifted by the hook member 52 of the wire 51, and the winding operation of the shutter curtain 1 by the winding shaft 4 performed by the forward rotation of the winding shaft 4 is performed after the lifting operation. As the fourth mounting member 58 rotates, the spirally wound shutter curtain 1 is smoothly unwound, and thereby the upper end of the shutter curtain 1 is pulled up by the hook member 52 of the wire 51. The winding of the shutter curtain 1 by the winding shaft 4 performed by the forward rotation of the winding shaft 4 can be performed smoothly. Can.

  In the embodiment described above, the upper end of the shutter curtain 1 is coupled to the take-up shaft 4 by one wire 51 at the center in the left-right direction among the three wires 51 provided in the left-right direction on the attachment base 40. For this purpose, the work for raising the upper end is performed, but the work for raising the upper end of the shutter curtain 1 may be performed using the three wires 51.

  Further, the seat plate 1A in FIG. 1 that forms the lower end of the shutter curtain 1 among the shutter curtains 1 is such that both left and right ends of the seat plate 1A are not inserted into the left and right guide rails 2. Therefore, the shutter curtain 1 formed in advance in the factory is assumed to exclude the seat plate 1A, and as described above, the shutter curtain 1 fed out from the winding shaft 4 by the reverse rotation of the winding shaft 4 is used. After the shutter curtain 1 is lowered and the both ends in the width direction are slidably inserted into the left and right guide rails 2, the seat plate 1 </ b> A may be connected to the lower end of the shutter curtain 1. .

  According to this, unlike the slat 1C, the seat plate 1A is a constituent member of the shutter curtain 1 having a large thickness dimension of the shutter curtain 1, and is thus placed on the second placement member 32 of the transport carriage 20 or the like. Therefore, when the shutter curtain 1 is wound in a spiral shape, this winding operation can be easily performed by reducing the diameter of the shutter curtain 1.

  Hooking the hook member 52 of the wire 51 to the upper end of the shutter curtain 1 is, for example, a hole provided in the uppermost slat 1C among the many slats 1C provided in order to form the shutter curtain 1. You may carry out by hooking on latching parts, such as protrusion. However, as described above, the above-described effects can be obtained by hooking the hook member 52 into the hole 68 formed as a bolt hole in the suspension member 1B provided at the upper end of the shutter curtain 1.

  In FIGS. 26 and 27, the shutter curtain 1 that is pulled up by the hook member 52 of the wire 51 and has the upper end connected to the winding shaft 4 rotates to the right on the fourth mounting member 58 of the attachment base 40. However, this direction of rotation may be reversed.

  FIG. 28 shows the building material placed on the second placement member 32 of the transport carriage 20, the winding shaft 4, and the shutter curtain that is wound around the winding shaft 4 with the upper end coupled to the winding shaft 4. The construction material of this embodiment is a combined body 70 of the winding shaft 4 and the shutter curtain 1. Also in this embodiment, after performing the same work as the work of FIG. 22 showing the case of the shutter curtain 1, the fork 61 of the forklift vehicle 60 is raised, as shown in FIG. 29. 70 can be transferred from the second mounting member 32 of the transport carriage 20 to the fourth mounting member 58 of the attachment base 40.

  FIG. 30 shows a state in which the combined body 70 is suspended and supported by the respective wires 51 provided on the attachment base 40 in the same manner as the winding shaft 4 of FIGS. 18 and 21. . In this embodiment as well, as in the case of the winding shaft 4, it is necessary to perform an operation for accurately receiving the neck portions 4 </ b> A provided at both ends in the axial direction of the winding shaft 4 with the two brackets 3. Therefore, among the three wires 51, the operator operates the transmitter described above with the two wires 51 supporting the two left and right sides separated in the axial direction of the winding shaft 4 in the combined body 70.
