[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Figures 1 and 2, a shutter 1 assembled by the shutter assembly method of this embodiment is installed on a building's structure so as to be able to open and close an opening in the structure, and comprises a frame body 2 and a shutter main body 4 (shutter device) which is assembled to the frame body 2 as shown in Figure 3. In the following description, the left-right direction of the shutter 1 is the X-axis direction, the up-down direction of the shutter 1 is the Y-axis direction, and the front-rear direction of the shutter 1 (view direction, indoor / outdoor direction) is the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other.

[0010] [Frame] The frame body 2 comprises left and right vertical frames 21, a top plate 22 screwed to the upper ends of the left and right vertical frames 21, an inspection plate 23 hung on the outer edge of the top plate 22, an upper frame 25 (lintel) attached to the upper part of the left and right vertical frames 21 but below the top plate 22, and a lower frame 26 attached to the lower ends of the left and right vertical frames 21. Guide rails 211 that vertically guide slats 3 (described later) are provided along the Y-axis direction on the left and right vertical frames 21. An engagement groove (not shown) is formed in the outer edge of the top plate 22 along the X-axis direction, and the inspection plate 23 is attached by having its upper edge hooked into the engagement groove along the X-axis direction of the top plate 22 and the left and right ends of its lower edge screwed to mounting pieces 473 of the side plates 47 (described later), and the inspection plate 23 can be removed from the frame body 2 by unscrewing the mounting pieces 473 of the inspection plate 23. The frame body 2 forms the storage section 20 in which the shutter main body 4 is disposed by the upper parts of the left and right vertical frames 21, the top plate 22, and the upper frame 25, and the storage section 20 can be opened and closed from the front side (outside the room) by attaching and detaching the inspection plate 23. A back plate 5 to which a side plate 47, which will be described later, is attached is attached to the upper parts of the left and right vertical frames 21 that define the storage section 20. The back plate 5 has extension pieces 51 that extend inward in the X-axis direction from the upper and lower edges, and the front sides of the extension pieces 51 are bent up and down to form case attachment pieces 52 to which the side plates 47 are detachably screwed.

[0011] [Shutter body] The shutter main body 4 is formed long in the X-axis direction, and includes a shutter curtain 41 composed of a plurality of connected slats 3, a shutter winding shaft 42 along the X-axis direction capable of winding up and unwinding the shutter curtain 41, and a shutter case 45 that houses the shutter winding shaft 42. The shutter winding shaft 42 incorporates a tubular motor (not shown) that drives the shaft body to rotate, a control unit that controls the operation of the tubular motor, and the like. The control unit is connected to a communication device that receives a remote signal from a remote control such as a remote controller, and controls the operation of the tubular motor based on the signal received by the communication device, thereby controlling the rotation of the shutter winding shaft 42. The shutter curtain 41 is configured by connecting the above-mentioned multiple slats 3 to each other so that they can rotate freely, and the uppermost slat 3 among the multiple slats 3 is attached to the shutter winding shaft 42, and the lowermost slat 3 is attached to a seat plate that sits on the lower frame 26. Therefore, the shutter curtain 41 moves up and down in the Y-axis direction while being guided by the guide rail 211 by the rotation of the shutter winding shaft 42. The shutter case 45 comprises a case back plate 46 aligned along the X-axis direction, and a pair of left and right side plates 47 whose rear portions are attached to the left and right edges of the case back plate 46 and protrude forward, and a resin side cap 7 which covers the side surface (outer surface) of the shutter body 4 is removably attached to the side plates 47 at a position forward of the upper part of the vertical frame 21 in the Z-axis direction.

[0012] Fig. 4 shows the side plate 47. Fig. 4(A) shows the side plate 47 as seen from the inside in the X-axis direction (the shutter winding shaft 42 side), and Fig. 4(B) shows the side plate 47 as seen from the front side in the Z-axis direction (the room outside). 4, the side plate 47 has a side plate main body 471 that rotatably supports one end of the shutter winding shaft 42, a pair of upper and lower mounting pieces 472 that are detachably screwed from the front to the case mounting piece 52 on the back plate 5 of the vertical frame 21, a mounting piece 473 to which the left and right ends of the lower edge of the inspection plate 23 are detachably screwed, and a pair of upper and lower cap mounting pieces 474 to which the side caps 7 are screwed. The cap mounting piece 474 is located forward of the position of the mounting piece 472, and the mounting piece 473 is located forward of the lower mounting piece 472. The side plate body 471 is flat, and a bearing member 475 that rotatably supports the shutter winding shaft 42 is attached to its approximate center. Here, on the inner surface side of the side plate body 471, there are provided an arc-shaped outer slat guide 61 that houses a communication device, an arc-shaped inner slat guide 62 that is disposed rearward of the outer slat guide 61 and houses wiring connected to the communication device or the like, and a rectangular lower slat guide 63 that is disposed below the outer slat guide 61, and these slat guides 61 to 63 guide the end portion of the slat 3 in the X-axis direction so as to suppress misalignment of the slat 3 in the X-axis direction relative to the shutter winding shaft 42. The mounting pieces 472, 473 and the cap mounting piece 474 extend inward in the X-axis direction toward the storage section 20. The upper and lower mounting pieces 472 extend inward in the X-axis direction from the upper and lower edges of the side plate body 471 and are configured along the Y-axis direction so as to be oriented to be screwed from the front side in the Z-axis direction. The mounting piece 473 extends inward in the X-axis direction from the lower edge of the side plate body 471 and is configured along the Z-axis direction so as to be screwed from the lower side in the Y-axis direction. The lower cap mounting piece 474 extends from the lower front edge of the side plate body 471 and is configured along the Y-axis direction so as to be screwed from the front side in the Z-axis direction, and the upper cap mounting piece 474 extends from the upper front edge of the side plate body 471 so as to be screwed from the front side in the Z-axis direction. The upper front edge of the side panel main body 471 is inclined in the Y-axis direction so that it is positioned rearward (further inside the room) than the position of the lower front edge, and therefore the upper cap mounting piece 474 is also positioned at a similar incline.

[0013] The side plate 47 described above is configured to be disposed so as to protrude forward from the vertical frame 21 in the Z-axis direction in an assembled state in which the shutter main body 4 is housed in the housing portion 20 and assembled to the frame body 2, and the portion of the side plate 47 protruding from the vertical frame 21 is referred to as a front portion 48 of the side plate 47. The mounting pieces 472, 473 and the cap mounting piece 474 described above are disposed on the periphery of the front portion 48. In addition, the front portion 48 is covered from the outside in the X-axis direction by the side cap 7 screwed to the cap mounting piece 474. A lower recess 481 is formed in the lower part of the front portion 48, and is defined in the Z-axis direction by the lower mounting pieces 472, 473. An upper groove portion 482 (slit portion) is formed in the upper part of the front portion 48, extending in a slit-like manner in the X-axis direction between the upper mounting piece 472 and the cap mounting piece 474, and is defined in the Z-axis direction. When the end 110 of the belt 11 described later is wound around the front portion 48, the belt 11 is passed through the lower recess 481 and the upper groove portion 482, as shown in (A) of Figure 6. As a result, when the end 110 of the belt 11 is wound around the front portion 48, the positional deviation in the Z-axis direction of the shutter body 4 relative to the belt 11 is suppressed by the lower recess 481 and the upper groove portion 482.

[0014] [Assembly aids] When the above-mentioned shutter main body 4 is to be assembled to the frame 2, the shutter main body 4 is lifted up using an assembly auxiliary tool 10 shown in FIG. The assembly aid 10 comprises a band-like belt 11 as a string-like body, hook members 12 as fasteners attached to both ends of the belt 11, and a length adjuster 13 and a neck support portion 14 (neck support pad) attached to the belt 11 between the hook members 12 at both ends. The length dimension of the belt 11 is longer than the dimension in the X-axis direction of the shutter body 4, and in this embodiment, it is composed of a fixed side belt portion 111 (fixed side string portion) provided on one side of the length adjustment device 13, and a length adjustment side belt portion 112 (length adjustment side string portion) provided on the other side of the length adjustment device 13 and longer than the fixed side belt portion 111. The length adjuster 13 is fixed to the fixed belt portion 111 and is configured as a belt winding ratchet adjuster that can wind up and adjust the length adjustable belt portion 112. The neck support portion 14 is composed of a cushion pad that is placed on the neck of the worker when manually lifting the shutter main body 4, and is attached so as to be slidable along the length adjustment side belt portion 112. The hook member 12 is engaged with the belt 11 so as to be slidable in its longitudinal direction, and in this embodiment, is formed with a C-shaped hook portion 121, but is not limited to this shape and may be formed, for example, with a D-shaped hook portion 123 having an opening / closing member 122 that opens and closes the opening. In this assembly aid 10, the hook members 12 are hooked to both ends 110 of the belt 11 to form annular portions (loop portions), which constitute the connecting portions 15. As shown in FIG.

[0015] The following describes the procedure for attaching the shutter body 4 to the frame body 2 when assembling the shutter 1. Also, it is assumed that a scaffold 8 used at a construction site is set up in front of the frame body 2 as shown in FIG. First, the installation aid 10 is prepared, both end portions 110 of the belt 11 are wound around the front portions 48 of the side plates 47 of the shutter main body 4, and the hook members 12 are engaged with both end portions 110 to form annular connecting portions 15 at both end portions 110 of the belt 11. Both end portions 110 of the belt 11 are wound around the front portions 48 of the side plates 47 through the lower recesses 481 and the upper grooves 482, respectively, thereby suppressing positional deviation of the connecting portions 15 in the Z-axis direction relative to the shutter main body 4. The length of the belt 11 is adjusted by the length adjuster 13 according to the dimension of the shutter main body 4 in the X-axis direction. Next, as shown in FIG. 3, the belt 11 is hung on the worker A, the neck rest 14 is placed around the neck of the worker A, and the shutter body 4 is lifted up via the assembly aid 10. The orientation of the shutter body 4 is finely adjusted manually by the worker A. When the shutter body 4 is lifted up, the belt 11 is pulled up against the weight of the shutter body 4, so that both ends 110 of the belt 11 slide slightly in the longitudinal direction relative to the hook member 12, and the annular connecting portion 15 tightens the front portion 48 of the side plate 47 and is firmly connected to the front portion 48. Furthermore, by tightening and connecting in this manner, the positional deviation of the connecting portion 15 relative to the shutter body 4 is further suppressed. Next, the lifted shutter body 4 is placed in the storage section 20 of the frame body 2. After the shutter body 4 is stored in the storage section 20 and is stabilized in the storage section 20, the worker A may finish lifting the shutter body 4 using the assembly aid 10. By finishing the lifting, the belt 11 is loosened, and in a state where the belt 11 is loosened and the hook members 12 can be easily released from the engagement with both ends 110 of the belt 11, the engagement is released and the assembly aid 10 is removed from the shutter body 4. The mounting pieces 472 of the side plates 47 are screwed to the case mounting pieces 52 (see FIG. 2) on the back plate 5 of the vertical frame 21. Since the shutter body 4 is assembled to the frame body 2 in this manner, even one person can easily hoist and assemble the shutter body 4 to the frame body 2, and the shutter body 4 can be stably placed in the frame body 2 even when worker A is crouching on scaffolding 8 as shown in Figure 3. After the shutter body 4 is assembled to the frame body 2, the side caps 7 are screwed to the upper and lower mounting pieces 472 of the side plate 47, and the inspection plate 23 is screwed to the mounting piece 473 of the side plate 47, and the shutter is assembled.

[0016] [Variations] In the above embodiment, as shown in Fig. 3, the worker A uses the assembly aid 10 to lift the shutter body 4 and assembles the shutter body 4 to the frame 2, but this is not limited to the above. For example, as shown in Fig. 7, a lifting machine 70 such as a hoist equipped with a chain block 72 or the like may be connected to the belt 11 of the assembly aid 10, and the shutter body 4 may be lifted based on the lifting force from the lifting machine 70. In this case, even if the shutter body 4 is larger and heavier, the lifting machine 70 can be connected to the assembly aid 10 connected to the shutter body 4, and the shutter body 4 can be easily lifted. The lifting machine 70 may be equipped with a trolley (not shown) that can move on rails.

[0017] In the embodiment, the hook members 12 are provided as fasteners on both ends of the belt 11 in the assembly aid 10, but the present invention is not limited to this and any fastener that can releasably fasten to the belt 11 may be used. For example, a belt buckle may be used that is fastened to the belt 11 by forming a hole in the belt 11 and inserting a shaft portion through the hole. In the above embodiment, the belt 11 is passed through the slit-shaped upper groove portion 482 in the front portion 48 of the side plate 47, thereby suppressing misalignment of the belt 11 in the Z-axis direction relative to the upper portion of the side plate 47. However, this is not limited to the above. When the connecting portion 15 is tightened and connected to the front portion 48 as described above, the tightening force of the connecting portion 15 suppresses misalignment relative to the side plate 47. Therefore, when this suppression of misalignment is necessary and sufficient, the belt 11 may be wound around the front portion 48 without passing it through the upper groove portion 482, as shown in (B) of Figure 6, and the configuration of the upper groove portion 482 itself may be omitted. In the above embodiment, the assembly aid 10 is equipped with a length adjuster 13 attached to the belt 11, but for example, if the shutter body 4 in which the assembly aid 10 is used has a specific length and the length of the belt 11 is appropriate for the shutter body 4, the configuration of the length adjuster 13 may be omitted. In the above embodiment, the neck support portion 14 is provided on the belt 11, but if the neck support portion 14 is not used, it may be omitted.

[0018] [Summary of the invention] (1) The shutter assembly method of the present invention is a shutter assembly method for assembling a shutter body formed to be elongated in the left-right direction to a frame body, wherein the shutter body is configured so that front portions at both ends thereof protrude forward from the frame body when assembled to the frame body, and is characterized in that an assembly aid having a string-like body and connecting portions formed at both ends of the string-like body is prepared, the connecting portions are connected to the front portions, respectively, the shutter body is lifted by the assembly aid, and the lifted shutter body is assembled to the frame body. According to the shutter assembly method of the present invention, since the assembly auxiliary tool is connected to the front part of the shutter body, the shutter body, which is a long and heavy object, can be easily lifted by the assembly auxiliary tool and can be assembled to the frame body while being lifted. This improves the workability of assembling the shutter body to the frame body. (2) In the shutter assembly method of the present invention, the shutter body includes a shutter curtain, a shutter winding shaft capable of winding up and unwinding the shutter curtain, and side panels supporting both ends of the shutter winding shaft and having the front portion, a lower recess defined in a front-to-rear direction perpendicular to the left-to-right direction is formed in the lower part of the front portion, and the connecting portion is configured by fastening devices attached to both ends of the string-like body being releasably fastened to the string-like body, and in the front portion, both ends of the string-like body, which are formed into a ring shape by fastening the fastening devices to the string-like body, may each be wound through the lower recess. With this configuration, both ends of the string-like body, which is formed into a loop by the locking device, are wound around the front part and pass through the lower recess mentioned above, thereby preventing both ends of the string-like body from shifting out of position in the front-to-rear direction from the front part of the side panel, making the lifted state of the shutter body more stable. (3) In the shutter assembly method of the present invention, an upper groove portion defined in the fore-and-aft direction is formed in the upper part of the front portion, and both ends of the string-like body, which is formed into a ring shape by engaging the engaging device with the string-like body, may be wound through the upper groove portion in the front portion. With this configuration, both ends of the string-like body, which is formed into a loop by the locking device, are wound around the front portion and pass through the upper groove portion mentioned above, thereby preventing both ends of the string-like body from shifting out of position in the front-to-rear direction from the front portion of the side panel, making the lifted state of the shutter body more stable. (4) In the shutter assembly method of the present invention, the locking device may be composed of a hook member that is engaged with the string-like body so as to be slidable in its longitudinal direction, and the front portion may be tightened to the connecting portion by the weight of the shutter body itself. With this configuration, when the shutter body is lifted with the assembly aid, the front part of the side panel is fastened to the connecting part by the weight of the shutter body. Therefore, when the shutter body is in the lifted state, the assembly aid can be firmly connected to the front part. Also, when the shutter body is not in the lifted state, the weight of the shutter body is not applied to the connecting part, so it is easy to release the connection of the assembly aid to the front part. (5) In the shutter assembling method of the present invention, the assembly assistant may include a length adjuster attached to the string-like body. According to this configuration, the length of the string-like body can be adjusted using the length adjuster in accordance with shutter bodies of various length dimensions, and these shutter bodies can be lifted appropriately. (6) In the shutter assembly method of the present invention, the string-like body has one side facing the length adjustment device as a fixed side string part and the other side facing the length adjustment device as a length-adjustable side string part, and the length-adjustable side string part may have a neck rest portion that is slidably moved in the longitudinal direction relative to the string-like body. With this configuration, as described above, the length of the string-like body can be adjusted according to the various lengths of the shutter body, and even if the length of the length-adjusting side string part is adjusted, the neck rest part can be positioned at the optimum position for lifting the shutter body. Also, since the neck rest part is provided on the length-adjusting side string part, the length-adjusting side string part can be provided longer than the fixed side string part, and the range in which the length of the string-like body can be adjusted can be made large. (7) In the shutter assembly method of the present invention, a lifting machine that imparts a lifting force to the assembly aid may be connected to the string-like body, and the shutter body may be lifted based on the lifting force from the lifting machine. With this configuration, even if the shutter body is too heavy to be lifted by hand, it can be easily lifted by connecting a lifting machine to the assembly aid connected to the shutter body. (8) The assembly aid of the present invention is characterized in that it is an assembly aid used in the shutter assembling method of the present invention described above. According to the assembly aid of the present invention, it is possible to configure an assembly aid that enables the shutter assembling method of the present invention described above to be carried out.
