). A horizontal groove part 3A is formed in the lower part of the concave side part and the lower part, and the opening part is wide and the depth part is narrow, so that about 90% of the tea scoop 2 can be stored in the shape of a horizontal hole.

The order in which the water-blocking sheet l is attached to the frame body 3 will be explained.

Push it into the groove 3A, and then tighten it by inserting a material into the gap in the horizontal groove 3A, inserting the pole lt into the hole that penetrates from the surface to the back of the tightening material t, and attaching it to the frame 3 at the same position. Oak) Screw into A and tighten as if pressing the elastic strip.
Hold the water-blocking sheet/. The upper side of the water-shielding sheet l is shielded by the wire 7 by hooking the ring parts 7A at both ends of the wire 7 wrapped around it into the hooks provided by inserting one end into the frame l/ at the triple-layered part of the frame on both side parts. Hold the top edge of the water sheet l. Additionally, two vertical cuts 2OA and 20B are made in the plane of the water-blocking sheet from the upper edge to near the lower edge.

The distance between the two cuts shall be the width necessary for people to enter and exit. On the opposing sheet edges of the n-th cut 2OA and 20B, a fastener having a suturing force that can withstand water pressure is attached to the outside, and a watertight fastener 10 is attached to the inner side so as to overlap with the fastener as shown in Fig. 4. . Wrap the wire 7 around the upper edge of the water-shielding sheet l between the cuts and fasten it with a folded hook H.

The action of the water-shielding sheet attached according to the present invention will be explained.

Tightening is done by tightening the bolt s on the material ≠, so that the slope part A provided on the material ≠ presses the elastic strip 2, so that the sheet edge is pressed against the inner surface of the horizontal groove 3A of the frame 3. Becomes watertight. Furthermore, as the water depth outside increases, water pressure is applied to the water-shielding sheet/, pushing the water-shedding sheet inward, causing the water-shielding sheet to form on the horizontal surface of the frame 3. It becomes watertight and prevents water from entering from outside. When installing preventive measures before a flood occurs, fasteners and IO
By opening it and removing the hook H at the top, an opening is created on the surface of the water-shielding sheet, which can be used for entering and exiting.

The above example shows the installation of a water-shielding sheet when the expected height of waterproofing is in the middle of a building opening, but if it is necessary to shield the entire opening such as a window from water, it is necessary to install the water-shielding sheet on the side of the water-shielding sheet in the previous example. This is possible by applying the processing on the lower side to the upper side.
