The operation for connecting the uppermost panel 10 to the base member 85 is performed by using the first hook portion 14 and the second hook portion provided as upper end hook portions and lower end hook portions on these panels 10. 15, the same work contents as the work for connection can be performed, and the work can be facilitated.

  The work for attaching the seat plate 8 to the second hook portion 15 at the lower end of the lowermost panel 10 is performed by fitting the hook portion 35 of the seat plate 8 shown in FIG. The hook portion 35 of the seat plate 8 has the same shape as the first hook portion 14 provided as an upper end hook portion on each panel 10, so that the seat plate 8 is attached to the lowermost panel 10. Can be performed in the same manner as the operation for connecting the uppermost panel 10 to the hanging member 85 and the operation for connecting the panels 10 to each other. 8 can also be facilitated.

  Also in this embodiment, as described above, each time each of the plurality of panels 10 is connected to the upper member, the rotating body 63 of the winding shaft 56 is rotated with respect to the Instead of winding the panel 10 on the winding shaft 56, all the panels 10 are vertically connected, and then the rotating body 63 of the winding shaft 56 is rotated with respect to the central axis 62 to wind these panels 10. You may make it wind up with the axis | shaft 56.

  After attaching the seat plate 8 to the second hook portion 15 at the lower end of the lowermost panel 10 as described above, the operator further operates the above-described operating device to thereby rotate the rotating body 63 of the winding shaft 6. Is rotated in reverse with respect to the central axis 62, whereby the seat plate 8 reaches the same height position as the lintel members 78, 79 or a position slightly lower than this, and then the left and right walls of the entrance 2 are closed. An operation of attaching the pair of left and right guide rails 4 shown in FIG. This mounting operation is performed by inserting the upper end of the guide rail 4 between the two mounting portions 57A and 57B as shown by the two-dot chain line in FIG. Both end portions in the width direction of the shutter curtain 1 at the lower portion of the panel 10 are inserted into a pair of left and right guide rails 4. Next, the operator rotates the rotating body 63 of the winding shaft 6 forward with respect to the center axis 62 by operating the operation device described above, whereby the shutter curtain 1 is unreeled from the rotating body 63. From the panel 10, an operation of inserting both ends in the width direction of each panel 10 into the left and right guide rails 4 is performed, whereby the shutter curtain 1 includes a pair of left and right guide rails 4 and these guide rails 4. Is guided by an extension portion 81 provided on the bracket 57 as a portion substantially extended upward, and can be freely opened and closed in the vertical direction.

  Thereafter, the remaining work such as bridging and disposing the cover member 58 shown in FIG. 15 between the pair of left and right brackets 57 attached to the building frame such as the upper wall of the entrance 2 is performed.

  The lintel members 78 and 79 are mounted on the mounting portions 57A and 57B of the pair of left and right brackets 57, and a slit 80 for vertically inserting the shutter curtain 1 between these mounting portions 57A and 57B. The forming operation may be performed as a part of the remaining operation described above.

  According to the embodiment described above, the upper end portion of the shutter curtain 1 is not directly connected to the rotating body 63 of the winding shaft 56, and the upper end portion is connected via the hanging member 85 formed of a flat plate material. The portion of the suspension member 85 that is coupled to the outer periphery of the wheel member 65 that constitutes the rotary body 63 while being coupled to the rotating body 63 is a wheel member 65 that has the outer shape of the winding shaft 56. Is formed in advance as a curved portion 85A having the same shape or substantially the same shape as a part of the outer shape of the shutter member 1, a suspension member 85 is interposed between the winding shaft 56 and the shutter curtain 1. Thus, even if the upper end of the shutter curtain 1 is connected to the winding shaft 56, the amount of protrusion of the curved portion 85A of the hanging member 85 from the outer peripheral surface of the winding shaft 56 does not increase. On the original member 85 Even if the shutter curtain 1 is wound, the winding diameter of the shutter curtain 1 on the winding shaft 56 does not increase. Therefore, even if the winding shaft 56 is stored inside the shutter case 55 shown in FIG. This shutter case 55 can be downsized.

  Further, each panel 10 constituting a main part of the shutter curtain 1 is configured such that a concave portion 11 and a convex portion 12 which are uneven in the thickness direction of the shutter curtain 1 are continuous in the opening and closing movement direction of the shutter curtain 1. Even if it is, the winding shaft 56 rotates and winds up the shutter curtain 1 in the hanging member 85, it is connected to the lower end of the curved portion 85A, and the flat plate hanging vertically downward. Since the winding shaft 56 starts winding the hanging portion 85 </ b> B, the shutter curtain 1 can be smoothly wound on the winding shaft 56, and the diameter of the winding on the winding shaft 56 can be reduced. Can be done.

  Further, as described above, each of the panels 10 constituting the main part of the shutter curtain 1 has the concave and convex portions 11 and 12 which are uneven in the thickness direction of the shutter curtain 1 continuous in the opening and closing movement direction of the shutter curtain 1. Even if the guide rails 4 are provided, an extension 81 that extends the guide rails 4 substantially upward is provided on the bracket 57 above the pair of left and right guide rails 4 to form the extension 81. Since the two portions 81A and 81B have a larger interval as they extend upward, the extension portion 81 has a shape that diverges upward and the bracket 57 of the two portions 81A and 81B. The one portion 81A close to the bearing portion 60 provided at the bottom does not reach the height position of the bearing portion 60, and the other portion 81B Since it has reached the same position as the height position, a position close to the height position of the bearing portion 60, or a position exceeding the height position of the bearing portion 60, the shutter curtain is rotated by the winding shaft 56 rotating in the direction A in FIG. When the shutter curtain 1 is unwound, and when the shutter curtain 1 is unwound from the winding shaft 56 by the rotating body 63 of the winding shaft 56 rotating in the direction opposite to the direction A, the weight of the seat plate 8 is light. Even if the winding diameter of the shutter curtain 1 around the rotating body 63 of the winding shaft 56 is large, the opening and closing movement of the shutter curtain 1 up and down can be performed as predetermined by the guide rail 4 and the extension 81, In particular, when the shutter curtain 1 having a large winding diameter is fed out from the rotating body 63 of the winding shaft 56, the portion 81 of the extension portion 81 having a large vertical dimension. The guiding action can be smoothly guided and the shutter curtain 1 from the extension portion 81 to the guide rail 4.

  The extension 81 may be formed above the guide rail 4 as a part of the guide rail 4.

  However, by providing the bracket 57 with an extension 81 for extending the guide rail 4 substantially above the guide rail 4 as in the present embodiment, as described above, At the installation site, after the hanging member 85 and the respective panels 10 constituting the shutter curtain 1 are wound by the rotation of the rotating body 63 of the winding shaft 56, the pair of left and right guide rails 4 are moved to the left and right sides of the entrance 2. The work of attaching to the building frame 3 such as a wall can be easily performed.

  When the maximum winding diameter D of the shutter curtain 1 shown in FIG. 19 is the natural winding diameter of the shutter curtain 1 when the shutter curtain 1 reaches the fully opened position, the two windings forming the extension 81 are formed. Of the portions 81A and 81B, the upper portion of the portion 81B having a long vertical dimension may be made to enter the inside of the maximum winding diameter D. According to this, it is possible to prevent the shutter curtain 1 that has reached the fully opened position from expanding significantly to the maximum winding diameter D in the natural state on the winding shaft 56 around which the shutter curtain 1 is wound.

  In the case where a plurality of suspension members 85 attached to the outer periphery of the winding shaft 56 are provided in the left-right direction, which is the width direction of the shutter curtain 1, as shown in FIG. Some or all of the members 85 may be aligned with the positions of the upper portions of the left and right guide rails 4. It is preferable to arrange them in When the hanging members 85 arranged at the left and right ends are arranged between the left and right guide rails 4 as described above, the hanging member 85 and the above-mentioned uppermost panel 10 which is a constituent member of the shutter curtain 1 are connected. Since the entire position of the connection point is a position exposed to the outside of the guide rail 4, when it is necessary to perform an operation of releasing the connection between the hanging member 85 and the uppermost panel 10, The work can be performed easily. Even when the number of suspension members is one having a large width in the left-right direction, it is preferable to arrange the suspension members between the left and right guide rails 4 for the same reason as described above.
