Description

The present invention is a type of stop in which a water blocking plate that closes the lower part of the opening is pressed against the building side or the floor side in order to prevent rainwater from entering through the opening of the building entrance or passage in the event of heavy rain or the like. Regarding water equipment.

Various water-stopping devices are widely used to prevent rainwater from entering from the front side of the water-stopping plate by blocking the lower part of the opening used as the entrance to the passage or parking lot with a water-stopping plate during rainfall. It is used. As such a device, it is composed of an opposed groove-shaped standing column that is closely fixed to the structure on both sides of the entrance of the structure and a waterproof plate that can insert both left and right ends into the groove of the standing column, and the bottom surface of the waterproof plate and the bottom surface of the waterproof plate. Elastic waterproof rubber is provided on the front of both left and right sides, the elastic waterproof rubber is rotated from vertical to horizontal on the floor surface and the inner surface on the front side of the groove, and the arm is rotated from vertical to horizontal. There is known a prevention device formed so as to hang a crescent that is simultaneously pressed and contacted by rotation and rotation between the front surface of a waterproof plate and the front surface of the vertical column (see, for example, Patent Document 1).

The waterproof device described in Patent Document 1 is easy to operate because it can be pressure-welded by a single operation by rotating the crescent, but the elastic waterproof rubber on the bottom surface of the waterproof plate may not be sufficiently crimped to the floor surface. is there. That is, when the waterproof plate is pressed in the vertical direction and the horizontal direction by one rotation at the same time, as described in Patent Document 1, the tip roller of the crescent arm is applied to the slope of the cam fixed to the vertical column to the front surface. By moving to the side, elastic waterproof rubbers provided at both ends of the waterproof plate are pressed against the inner surface on the front side of the facing groove, and at the same time, the tip roller is applied to the lower surface of the upper end protrusion of the cam to lower the waterproof plate and lower the bottom surface. The elastic waterproof rubber of is pressed against the floor surface. However, when the tip roller is applied to one cam to move the waterproof plate in the horizontal direction, the elastic waterproof rubbers provided at both ends are elastically deformed and the waterproof plate is in close contact with the vertical column, and the waterproof plate is lowered at the same time in that state. In order to make it work, it must be lowered against the force acting in the horizontal direction of the waterproof plate, so a very large force is required. In reality, the amount of the waterproof plate descending is small, and there are many situations in which the elastic waterproof rubber on the bottom is elastically deformed only by the weight of the waterproof plate, which may make the waterproofing at the lower end uncertain. .. Further, the waterproof device described in Patent Document 1 engages a crescent tip roller with one cam to move the waterproof plate simultaneously in the front-rear direction and the downward direction, but forces in the front-rear direction and the downward direction. When the above forces are applied to one place at the same time, a large force is concentrated on the cam and the tip roller portion, which requires a large force and may cause damage.
