Description

  The present invention relates to a reinforcing structure for a sliding shutter installed in an opening of a building, and more particularly to a reinforcing structure for a sliding shutter that is slidably held on a reinforcing body rail provided along a guide rail.

  The sliding shutter that opens and closes the building opening is configured to open and close the building opening by guiding a shutter plate composed of a plurality of slat plates connected vertically to guide rails installed on both side edges of the building opening. (For example, Patent Document 1). When such a sliding shutter is blown by a strong wind, the slat plate flutters and collides with the guide rail and easily generates noise. Further, the slat plate may be damaged by the wind pressure.

  In order to solve the above problem, the applicant of the present application has proposed a shutter reinforcing member 101 that reinforces the sliding shutter 100. As shown in FIG. 15, the shutter reinforcing member 101 has a cylindrical member 102 formed in a cylindrical shape having an opening at one end, and can be extended and stored by sliding one end into the cylindrical member 102. Are provided on each of the slide member 103, the locking screw 104 for fixing the cylindrical member 102 and the slide member 103 at predetermined positions, and the other end of the cylindrical member 102 and the other end of the slide member 103. And a claw portion 107 that is inserted into a gap between the pair of guide rails 105 of the sliding shutter 100 and the slat plate 106 (see Patent Document 2).

  Then, the slide member 103 is housed in the cylindrical member 102, and the shutter reinforcing member 101 is brought into contact with the slat plate 106 of the sliding shutter 100 in a state where the shutter reinforcing member 101 is slightly shortened to guide the claw portion 107. The shutter reinforcing member 101 is stretched so as to be inserted into the gap between the rail 105 and the slat plate 106, and the locking screw 104 is tightened, whereby the shutter reinforcing member 101 is fixed to the sliding shutter 100 and reinforced. As described above, the shutter reinforcing member 101 can be easily attached to the gap between the guide rail 105 and the slat plate 106 conventionally provided in the sliding shutter, and the sliding shutter 100 can be reinforced very easily. it can.
