Description

  The present invention is a water stop plate of a type in which a water blocking plate for closing the lower part of the opening is pressed against the building side or the floor side in order to prevent rainwater from entering from the opening of a building entrance or passage when heavy rain etc. It relates to water equipment.

  Various water blocking devices are widely used to block the lower part of the opening used as the entrance of the aisle or the parking lot with a water blocking board during rainfall to prevent the ingress of rain water from the front side of the water blocking board It is used. As such a device, it comprises an opposite groove-shaped upright fixedly fixed to the structure on both sides of the entrance of the structure, and a waterproof board capable of inserting both left and right ends into the groove of the upright pillar. An elastic water-stop rubber is provided on the front of the left and right sides, and the elastic water-stop rubber is rotated from vertical to horizontal on the floor surface and the inner surface on the front side of the groove, There is known an preventing device formed so as to bridge a crescent to be pressed simultaneously at the same time by a rotational movement between the front surface of the waterproof board and the front surface of the upright column (see, for example, Patent Document 1).

  The waterproof device described in Patent Document 1 is easy to operate because the pressure contact is completed by the one-time operation by the rotation of the crescent, but the elastic water-stop rubber on the bottom surface of the waterproof board is not sufficiently crimped to the floor surface is there. That is, when pressing the waterproofing plate simultaneously in the vertical direction and the horizontal direction simultaneously by one rotation, as described in Patent Document 1, the tip roller of the crescent arm is applied to the slope of the cam fixed to the upright column By moving to the side, the elastic water-stopping rubber provided on both ends of the waterproof plate is pressed against the inner surface of the front face of the opposite groove, and simultaneously the tip roller is put against the lower surface of the upper end projection of the cam to lower the waterproof plate. The elastic water-stop rubber is pressed against the floor surface. However, when the tip roller is put against one cam and the waterproof board is moved in the horizontal direction, the elastic water blocking rubber provided at both ends is elastically deformed and the waterproof board adheres to the upright column, and the waterproof board is simultaneously lowered in that state. This requires a very large amount of force because it must be lowered against the horizontal force of the waterproof board. In fact, the amount by which the waterproof board descends is small, and many situations may occur where the elastic water-stop rubber on the bottom is elastically deformed only by the weight of the waterproof board, and the waterproofing of the lower end may become uncertain. . Furthermore, although the waterproof device described in Patent Document 1 engages the tip roller of the crescent with one cam to simultaneously move the waterproof plate in the front-rear direction and the downward direction, the force in the front-rear direction and the downward direction If one of them is applied to one place at the same time, a large force acts on the cam and the tip roller portion, which requires a large force and may cause damage.
