Description

  The present invention relates to a flexible divided tide plate that can be moved up and down at a building opening, and more particularly to an improved technique that enables the tide plate to be wound around a storage unit that is disposed in a ceiling of a building.

  Inundation damage to buildings has become a major problem due to typhoons, heavy rains, or sudden rainfall in rivers and beaches, especially in low-elevation areas. Not only large-scale disasters, but even a few centimeters of inundation can cause rainwater that has entered a building to damage flooring and furniture. Inundation is also a problem in a building structure having a space lower than the ground, that is, a basement. In the lower part of the opening of the building, there is a thing that a tide plate can be arranged for such damage. This type of tide plate has traditionally been provided with a U-shaped groove facing each other on both sides of the opening of the building, and both ends of the dam plate are fitted into this groove during water discharge.

  However, with such a tide plate structure using a dam plate, it is necessary to transport and install a dam plate stored at a remote location each time the water is discharged. There was a problem that it took time and was necessary to remove and transport the weir plate to a storage box or the like at a remote location.

To solve such a problem, there is a tide plate combined shutter disclosed in Patent Document 1. As shown in FIG. 17, the tide plate / shutter 1 has a predetermined height below the shutter curtain 7 which can be raised and lowered along the guide rails 5 and 5 provided on the left and right of the building opening 3. One tide plate 9 is connected. When the wind-up device 13 is driven by the operation switch 11, the tide plate 9 winds up the shutter curtain 7, and rises the building opening 3 while being guided by the guide rails 5 and 5. Become. When the tide plate 9 is not in use, the shutter curtain 7 is supported in a state where the shutter curtain 7 hangs downward from the storage port 17 of the storage unit 15 as shown in FIG. .
