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. For example, as shown in FIG. 14A, pillars 1 having insertion grooves 2 are erected on both sides of the opening 3 of the building, and both ends of the water blocking plate 4 are inserted into the grooves to make the water blocking plate The water blocking plate 4 is pressed against the inner surface of the groove 2 of the column by the lock members 5 provided vertically and horizontally, and pressed against the floor 6 of the opening. There is known a water blocking device in which the provided elastic water blocking member 7 is crimped. A lock handle 8 and a receiving piece 9 are provided as the lock member 5, the lock handle 8 is provided on the water blocking plate 4, the receiving piece 9 is provided on the support 1, a cam and an upper end projection are formed on the receiving piece, When the arm of the lock handle is turned from the vertical direction to the horizontal direction, the tip roller of the lock handle is brought into contact with the cam and the upper end projection provided on the receiving piece by this one-shot rotation, A device has been proposed which simultaneously moves the elastic water blocking member 7 in contact with the inner surface of the groove of the support and the floor (for example, a patent). Reference 1).

  In the waterproof device described in Patent Document 1, the tip roller of the lock handle is engaged with one receiving piece having a cam by a single operation by turning, and the water blocking plate is simultaneously moved in the back and forth direction and downward direction. However, if force is applied to one place at the same time in the back and forth direction and downward direction, large force will be concentrated on the receiving piece and the tip roller part, requiring large force and causing damage. There was also. In addition, when simultaneously moving in both directions, if the action of pressing the water blocking plate in the back and forth direction is insufficient, a gap is generated between the columns and there is a possibility that water may be flooded from below the water blocking plate. That is, in order to enable both ends of the water blocking plate to be inserted into the groove 2 of the column 1, the gap between the grooves is formed larger than the thickness of the water blocking plate, so the water blocking plate was dropped into the groove of the column. In the state, as shown in FIG. 14B, a minute space 54 is formed between the water blocking plate and the inner surface of the groove. On the other hand, since the water blocking plate 4 is lowered by its own weight, as shown in FIG. 14C, the elastic water blocking member 7 provided on the bottom surface of the water blocking plate is in contact with the floor 6. At the initial stage where flooding to the opening 3 is gradually starting during rainfall, there is a possibility that water may infiltrate early from the side of the water blocking plate 4 through the minute space 54, so the minute space 54 Must be closed immediately. In such a state, as described in Patent Document 1, when a load is applied to the water shut-off plate so that the lock handle is rotated to press simultaneously in the back and forth direction and the downward direction, the lower end of the water shut-off plate is floor surface Since the force F pressing in the vertical direction acts as a frictional resistance against the force H for moving the water blocking plate 4 horizontally, the force F acting in the vertical direction acts as a cause to prevent the smooth movement of the lower portion of the water blocking plate. Become. As a result, the lower portion of the water blocking plate 4 may not be sufficiently pressure-bonded to the inner surface of the groove 2, and even if it can move, the micro space 54 may not be closed reliably, which may cause flooding. Furthermore, as described in Patent Document 1, although the lock handle of the water blocking plate depends on the size of the water blocking plate, generally, the total of 4 independently at the upper and lower sides of the plate surface both sides of the water blocking plate. Because it is located in place, it is not possible to operate all lock handles early at once. In addition, if the operation procedure of the lock handle located at the upper part of the plate surface of the water blocking plate and the lock handle located at the lower part is not correct, the micro space can not be completely closed or the closing is delayed and the lower part of the water blocking plate The amount of inundation from water may increase.
