The take-up lever 25 is rotationally locked to prevent slack when the water blocking sheet is in the stretched state in FIGS. 3 and 4 and when the end stopper 20 in FIGS. 1 and 2 is in the returned state.

  Reference numeral 27 denotes a holding means, which is a fixed receiving plate 28 fixed by a fixing tool 28a vertically inside the outer case 8 on the front surface of the left and right side walls 1 and 2 and inside the end receiving member 21; It consists of a holding plate 30 which is held in contact with the front surface of the plate 28 and fixed in parallel to the fixed receiving plate 28 by a wing bolt 29. A hinge 32 is provided at the lower end of the fixed support plate 28 as shown in FIG. 5 so that the holding plate 30 attached thereto is opened forward or closed backward. Moreover, while the recessed part 33 is provided in the holding plate 30 in the fixed receiving plate 28, the convex part 34 is provided, when the holding plate 30 is opened, the water blocking sheet 18 is let through, and when the holding plate 30 is closed, the said unevenness is said The portions 33 and 34 engage with each other to stop the movement of the water blocking sheet 18.

In addition, as shown in FIG. 6, the end stopper 20 may be formed by integrating the sheet end by winding several times on a vertically long flat core plate 36.
In addition, as shown in FIG. 6, a lower tongue 37 having a narrow width is provided at the lower edge of the water blocking sheet 18 so that it can be deployed in the forward direction, and the pressing as shown in FIG. The band plate 38 is mounted, and the fastening tool 39 is held by the through hole of the holding plate 38 and the through hole 37a of the lower tongue 37 through the through hole 37a of the external floor surface 6 (FIG. 1) The lower tongue piece 37 is in close contact with the lower surface by being screwed in so that it does not easily float and it is possible to reliably prevent water immersion. The lower tongue 37 and the main body portion of the water blocking sheet 18 can be closely wound with male and female surface fasteners a and b (refer to FIG. 6) so that winding is possible.
As shown in FIG. 4, the water blocking sheet 18 supports the hanging members 43 by hanging them on the hanging wires 42 passed between the left and right end support members 21 and 21 extended high. It may be held without drooping, and the water blocking function may be surely performed.

  1 and 2 show the state of the water shut-off device in the time of peace. In normal times, the shutter 4 may be open or closed. The water blocking sheet 18 is rewound by the force of the rewinding material 19 and the winding lever 25 is rotationally locked and the end stopper 20 is stopped in the front side corresponding to the slit 9 of the outer case 8 and retracted. There is. The holding means 27 is in a state where the holding plate 30 is fixed to the fixing means 28 side by the butterfly bolt 29.

  Before the flood, tsunami, high waves, etc., as shown in Fig. 1 and Fig. 2, the shutter 4 is closed and then the lock of the take-up lever 25 is released and the butterfly bolt 29 is made as shown in the right column of FIG. Loosen it so that the holding plate 30 is opened to the front. If the lower end of the holding plate 30 is cut obliquely as shown in FIG. 5, the holding plate 30 can be opened to a certain angle and can not be opened further. If the holding plate 30 opens too much to the external floor surface 6, a series of water blocking operations will be hindered, but if the predetermined angle is specified, the operation will be facilitated.

  In addition, although the convex part 34 of the clamping plate 30 can not create the clearance gap for passing the water blocking sheet 18 between the lower parts of the fixed receiving plate 28 if it extends to the lower end, it is convex like the right column of FIG. If the portion 34 is short from the lower end to a short distance, a through gap is secured and the water blocking sheet 18 can be easily passed in the closing direction. The water blocking sheet 18 is wound as shown in FIGS. 1 and 2, but in the wound state, the lower tongue 37 is folded as shown by the solid line in FIG. 6 and held by the surface fasteners a and b. It is considered to be

  After that, when the end stop 20 on the right side is taken out in the direction of the entrance 3, the water shut-off sheet 18 is pulled out in the outer case 8 and is held open as shown in the right column of FIG. The end stop 20 is pulled out between the means 27 and 27 until it corresponds to the end support 21. The end stopper 20 is fixed to the end support 21 by a wing bolt 23.

  After that, the take-up lever 25 is turned clockwise to pull the water shut-off sheet 18 in a pulled state and locked, and the left and right two holding plates 30 are pressed against the fixed receiving plate 28 side.

Since the water blocking sheet 18 has aramid fibers as a main layer and is sandwiched and fixed by the sandwiching means 27 near the right and left ends near the right and left ends, more reliable water blocking is performed. If the left and right length of the lower tongue piece 37 is made to exactly correspond to the distance between the left and right sandwiching means 27, the infiltration of water through the X portion in FIGS. 3 and 4 can be suppressed.

The water blocking sheet 18 may be made of only a lightweight, strong reinforcing fiber sheet 46 made of aramid fibers, carbon fibers and the like represented by broken lines as shown in FIG. 6A. In this case, in order to prevent water permeation from the fiber, a surface containing a soft rubber or resin is impregnated into the eyes to prevent water permeation. As shown in (b) of FIG. 6, even if the resin sheet 47 described above is integrated on the back side of the reinforcing fiber sheet 46 or on the front side as in (c) by adhesion or fusion, Good. Alternatively, as shown in FIG. 6 (d), the water blocking sheet 18 may be prepared by integrally holding the reinforcing fiber sheet 46 between the front and back resin sheets 47, 47, or as shown in (e). The sheet 46 may have a plurality of layers such as two layers. In these, although the reinforcing fiber sheet 46 shall be knitted in all directions, you may employ | adopt what is knitted in a diagonal lattice shape.
Further, as shown in FIG. 6, the width of the holding plate 30 is w, which is the same as that shown in FIG. 1 to FIG. It may be a plate extending to 3 sides. The positional relationship between the right end 30a of the holding plate 30 and the right end 28a of the fixed support plate 28 with the end of the lower tongue 37 is shown in FIG. 6, but the lower tongue 37 is between the right ends 30a and 28a. It is done like that. The same can be applied to the holding means 27 constituted by the fixed receiving plate 28 and the holding plate 30 on the right side of the entrance 3. In this way, the water pressure applied to a portion of the water blocking sheet 18 corresponding between the right end 30 a and the left end of the lower tongue 37 is properly received by the right end portion of the fixed support plate 28, so that the lower end of that portion Water is prevented from entering.
