It needs to be lifted to a high position. The water stop plate is heavy because it needs to be strong enough to withstand high water pressure. Therefore, it is difficult to manually lift the water stop plate to a position higher than the opposing groove of the support (for example, 1 meter or more). For example, an inexperienced worker such as an elderly person or a woman installs the water stop plate. Had the problem of being difficult.

  An object of the present invention is to provide a water stop device capable of quickly and easily installing a water stop plate in order to improve such a current situation.

  The water stop device of the present invention is a water stop device provided with left and right supports installed at intervals and a water stop plate detachably attached to the left and right supports. The water stop plate has a locking projection protruding from the surface in contact with the support toward the support, and the water stop plate is moved in the front-rear direction with respect to the support. At the same time, the water blocking plate is connected to the support by inserting the lock protrusion into a lock hole provided in the support and locking it.

  Next, the structure of the supports 2L and 2R will be described. As shown in FIG.1 and FIG.2, the support bodies 2L and 2R have a square columnar form with a hollow structure, and have a bilaterally symmetric configuration. Therefore, the left support 2L as viewed from the front side (front side) of the doorway E will be described, and a detailed description of the right support 2R will be omitted.

  As shown in FIGS. 8 to 10, the support 2 </ b> L has a substantially rectangular shape in plan view, and the water stop plate mounting surface portion 21 positioned in front as viewed from the front side of the entrance E and the left and right sides of the water stop plate mounting surface portion 21. The left and right outer side surface parts 23 and the left and right inner side surface parts 24 connected to the end part, and the cover part 25 arranged to face the water stop plate attaching surface part 21 are provided. The lower end side of the support 2L is closed by a plate-like bottom surface portion 26. The upper end side of the support 2 </ b> L is closed by a plate-like top surface portion 27.

  The left and right outer surface portions 23 of the support 2L are fixed to the left side wall W of the entrance E with a plurality of side surface fixing screws 28. Further, the bottom surface portion 26 is fixed to the floor surface F located at the left end portion of the entrance E with a plurality of bottom surface fixing screws 29. Watertightness is ensured between the left and right outer side surface portions 23 and the side wall W and between the bottom surface portion 26 by a water stop material such as an adhesive or an elastic body.

  Locking holes 22 into which the locking protrusions 32 of the waterstop plates 3A and 3B are fitted are provided at two locations above and below the waterstop plate mounting surface portion 21. The locking projections 32 of the water stop plate 3A or 3B are fitted into one locking hole 22, and the locking projections 32 of the water blocking plate 3B or 3A are fitted into the other locking hole 22.

  The locking hole 22 includes a head insertion hole 22a through which the head 32a of the locking projection 32 of the water blocking plates 3A and 3B can be inserted, and a shaft insertion groove 22b extending downward from the head insertion hole 22a. And has a substantially keyhole shape that is vertically long and vertically long. The width dimension of the shaft insertion groove 22b extending vertically is smaller than the width dimension of the head 32a of the locking projection 32, and is smaller than the width dimensions of the shaft 32b and the reinforcing rib 32d of the locking projection 32. large. The lower side 22c of the head insertion hole 22a is divided into left and right sides with the shaft portion insertion groove 22b interposed therebetween, and each lower side 22c is inclined so as to be positioned downward toward the shaft portion insertion groove 22b side.

  A head holding portion 30 that is disposed below the head insertion hole 22a of the locking hole 22 and holds the head 32a of the locking projection 32 is provided inside the support 2L. In the present embodiment, a pair of left and right head holding portions 30 are provided for one locking hole 22. The head holding portion 30 is attached to the inner side surface of the water stop plate attachment surface portion 21 with the shaft portion insertion groove 22b of the locking hole 22 interposed therebetween.

  The head holding portion 30 has a substantially wedge shape, and a head slide surface 30a that inclines away from the water stop plate mounting surface portion 21 toward the lower side, and a locking projection provided below the head slide surface. It includes a left and right horizontally elongated groove-like head holding recess 30b into which the head 32a of the portion 32 is fitted.

  Further, a release device 41 is provided inside the support body 2L so that the head 32a of the locking projection 32 held in the head holding recess 30b can be flipped up by rotating the operation handle 42. . In this embodiment, the upper and lower release devices 41 are attached to the inner wall surface of the left and right inner side surface portions 24 side by side.

  The release device 41 includes an operation handle 42 having a grip portion 42a held by an operator at one end and an action portion 42b at the other end. A midway portion of the operation handle 42 is pivotally supported by a base member 43 attached to the left and right inner side surface portions 24. That is, when the operator pulls the grip portion 42a toward the near side and rotates it downward, the action portion 42b rotates upward. Further, below the base member 43, a handle fixing member 44 that is engaged with the action portion 42 b of the operation handle 42 to fix the position of the operation handle 42 is provided.

  In the support body 2L, the cover portion 25 is provided so as to be opened and closed by a hinge member 45. The cover portion 25 is fixed in a non-rotatable state by a fixing tool such as a cylinder lock or a magnet (not shown) in a closed state.

  Next, with reference to FIGS. 11 to 15, an operation of attaching the water stop plates 3A and 3B to the supports 2L and 2R will be described. 11 to 15 show only the support 2L among the supports 2L and 2R. However, since the supports 2L and 2R are provided symmetrically as described above, the same applies to the support 2R. Is installed.

  As shown in FIG. 12, the water stop plate 3A is disposed so as to face the supports 2L and 2R, the water stop plate 3A is lifted up slightly, and the heads of the locking holes 22 below the supports 2L and 2R. The head portion 32a of the locking projection 32 of the water stop plate 3A is inserted into the insertion hole 22a (see also FIGS. 11A and 11B).

  As described above, the locking projection 32 of the water stop plate 3A is disposed at the same position on the standing surface portion 31 regardless of the vertical direction, left and right direction, and front and rear direction of the water stop plate 3A. Therefore, an operator who attaches the water stop plate 3A can quickly insert the head portion 32a of the locking projection 32 into the head insertion hole 22a of the locking hole 22 without confirming the direction of the water stop plate 3A.

  When the operator removes the force of lifting the water stop plate 3A, the water stop plate 3A is displaced downward by the weight of the water stop plate 3A, and the shaft portion 32b and the reinforcing rib 32d of the lock protrusion 32 are locked into the lock holes. The head portion 32 a is in contact with the head slide surface 30 a of the head holding portion 30. Here, even if the shaft portion 32b and the reinforcing rib 32d are displaced in the left-right direction with respect to the shaft portion insertion groove 22b when the head portion 32a is inserted into the head insertion hole 22a, the shaft portion 32b and the reinforcing rib 32d are disposed. Is guided to the shaft insertion groove 22b along the lower side 22c inclined downward toward the shaft insertion groove 22b. Accordingly, the shaft portion 32b and the reinforcing rib 32d can be easily and reliably fitted into the shaft portion insertion groove 22b. Further, the tip of the stopper projection 37 on the lower side of the water stop plate 3 </ b> A is inserted into the stopper receiving recess 40 of the floor surface F.

  When the water stop plate 3A is pushed so as to slide downward, the head portion 32a of the locking projection 32 is attached to the support members 2L and 2R along the head slide surface 30a of the head holding portion 30. It moves obliquely downward so as to be away from the surface portion 21. At this time, the standing surface portion 31 of the water stop plate 3 </ b> A is displaced so as to approach the water stop plate mounting surface portion 21, and the standing surface portion packing member 33 comes into close contact with the water stop plate mounting surface portion 21 and is pressed and deformed.

  As shown in FIG. 13, when the water stop plate 3A is further slid downward, the head portion 32a of the locking projection 32 reaches the head holding recess portion 30b of the head holding portion 30, and the axis of the head portion 32a. The portion closer to the portion 32b fits into the head holding recess 30b (see also FIG. 11C). The head portion 32a is biased to the head holding recess portion 30b by the restoring force of the rising surface portion packing member 33 made of an elastic body, and is held in the head holding recess portion 30b.

  Thus, after inserting the head 32a of the locking projection 32 of the water stop plate 3A into the head insertion hole 22a of the lock hole 22 of the supports 2L and 2R, the water stop plate 3A is simply slid downward. With a simple operation, the water stop plate 3A can be reliably connected to the supports 2L and 2R, and the upward movement of the water stop plate 3A is restricted, so that the water stop plate 3A can be prevented from rising.

  Further, the front and rear direction packing member 35 (see FIG. 3 and the like) and the horizontal plane portion packing member 36 on the lower side of the water stop plate 3A in a state where the head portion 32a of the locking projection portion 32 is fitted in the head holding recess portion 30b. It is in close contact with the floor surface F and is deformed by pressing. Thereby, high watertightness is securable between the water stop plate 3A and the floor surface F. Moreover, since the front end side of the stopper projection 37 on the lower side of the water stop plate 3A is inserted into the stopper receiving recess 40 of the floor surface F, the curvature of the water stop plate 3A due to water pressure can be reduced, and the water stop plate 3A It is possible to prevent deterioration of water tightness and damage to the water stop plate 3A due to bending.

  Subsequently, as shown in FIG. 14, the water stop plate 3B is disposed so as to face the support bodies 2L and 2R to which the water stop plate 3A is attached, and the water stop plate 3B is lifted above the water stop plate 3A. Then, the head portion 32a of the locking projection 32 of the water stop plate 3B is inserted into the head insertion hole 22a of the locking hole 22 on the upper side of the supports 2L and 2R.

  Similarly to the water stop plate 3A, the water stop plate 3B has the locking projections 32 arranged at the same position on the standing surface portion 31 regardless of the direction of the water stop plate 3B. Therefore, the operator who attaches the water stop plate 3B can quickly insert the head portion 32a of the locking projection 32 into the head insertion hole 22a of the lock hole 22 without confirming the direction of the water stop plate 3B.

  When the operator removes the force to lift the water stop plate 3B, the water stop plate 3B is displaced downward as in the case of attaching the water stop plate 3A, and the head portion 32a of the locking projection 32 becomes the head holding portion. It abuts on 30 head slide surfaces 30a. The tip of the stopper projection 37 on the lower side of the water stop plate 3B is inserted into the stopper receiving recess 38 on the upper side of the water stop plate 3A, while the tip of the stopper projection 37 on the upper side of the water stop plate 3A is inserted. It is inserted into the stopper receiving recess 38 on the lower side of the water stop plate 3B.

  When the water stop plate 3B is pushed so as to slide downward, the head 32a of the locking projection 32 extends along the head slide surface 30a of the head holding portion 30 in the same manner as when the water stop plate 3A is attached. As the plate moves diagonally downward, the standing surface portion 31 of the water stop plate 3B is displaced so as to approach the water stop plate mounting surface portion 21, and the standing surface portion packing member 33 of the water stop plate 3B comes into close contact with the water stop plate mounting surface portion 21. At the same time, it is deformed by pressing.

  As shown in FIG. 15, when the water stop plate 3B is further slid downward, the head 32a of the locking projection 32 reaches the head holding recess 30b and rises up, as in the case of mounting the water stop plate 3A. The head 32 a is fitted into the head holding recess 30 b by the restoring force of the surface packing member 33. In this way, after inserting the head 32a of the locking projection 32 of the water stop plate 3B into the head insertion hole 22a of the upper locking hole 22 of the supports 2L and 2R, the water stop plate 3B is slid downward. With this simple operation, the water stop plate 3B can be reliably connected to the supports 2L and 2R, and the upward movement of the water stop plate 3B is restricted, so that the water stop plate 3B can be prevented from being lifted.

  Further, with the head 32a of the locking projection 32 of the water stop plate 3B fitted into the head holding recess 30b, the front and rear direction packing member 35 and the horizontal surface portion packing member 36 below the water stop plate 3B, The front-rear direction packing member 35 and the horizontal surface packing member 36 on the upper side of the water stop plate 3A are brought into contact with each other and pressed and deformed. Thereby, high watertightness is securable between the water stop plate 3A and the water stop plate 3B.

  Further, the distal end side of the stopper projection 37 on the lower side of the water stop plate 3B is inserted into the stopper receiving recess 38 on the upper side of the water stop plate 3A, and the front end side of the stopper projection 37 on the upper side of the water stop plate 3A is stopped. It is inserted into the stopper receiving recess 38 on the lower side of the plate 3B. Thereby, the curvature of the water stop plates 3A and 3B due to the water pressure can be reduced, and the deterioration of water tightness and the damage of the water stop plate 3A due to the curvature of the water stop plates 3A and 3B can be prevented.

  Next, with reference to FIG. 16, the operation of removing the water stop plates 3A and 3B attached to the supports 2L and 2R will be described. In FIG. 16, the support 2L is shown out of the supports 2L and 2R. However, since the supports 2L and 2R are provided symmetrically as described above, the same removal operation is performed on the support 2R. Is called.

  First, the cover portion 25 of the support 2L is opened, and the release device 41 is made operable. Of the two upper and lower release devices 41, the grip 42 a of the operation handle 42 of the upper release device 41 is gripped, and the grip 42 a is pulled to the near side (opposite to the water stop plate mounting surface portion 21) and rotated downward. With the downward rotation of the grip portion 42 a, the action portion 42 b of the operation handle 42 rotates upward and comes off the handle fixing member 44.

  When the gripping part 42a is further turned downward, the action part 42b is further turned upward, comes into contact with the head part 32a of the locking projection 32 of the water stop plate 3B from below, and pushes up the head part 32a. The head 32 a moves away from the head holding recess 30 b of the head holding portion 30 and moves to the lower end portion of the head sliding surface 30 a, and the head 32 a of the locking projection 32 and the head holding of the head holding portion 30 are moved. The engagement with the recess 30b is released (see FIG. 16A).

  In a state where the engagement between the head portion 32 a and the head holding recess portion 30 b is released, the head portion 32 a of the locking projection 32 is a standing surface portion packing member 33 between the standing surface portion 31 and the waterstop plate mounting surface portion 21. Is pressed against the head slide surface 30a. Thereby, even if the action part 42 b of the operation handle 42 is separated from the head part 32 a of the locking projection part 32, the head part 32 a is configured not to be fitted again into the head holding recess part 30 b of the head holding part 30. Yes.

  Further, when the engagement between the head 32 a and the head holding recess 30 b is released, the head 32 a of the locking projection 32 is brought into contact with the head slide surface 30 a of the head holding part 30. Therefore, the head portion 32 a is configured not to come out of the locking hole 22. Thereby, when the operator operates the operation handle 42, the water stop plate 3B can be prevented from being unexpectedly detached from the supports 2L and 2R, and an accident caused by the water stop plate 3B falling or falling can be prevented. The safety of the water stop plate removal work can be improved, and damage to the water stop plate 3B can be prevented.

  The operator operates the operation handle 42 of the upper release device 41 on the left and right supports 2L and 2R to hold the head 32a of the locking projection 32 and the head holding portion 30 of the water stopping plate 3B. The engagement with the recess 30b is released. In this state, the water stop plate 3B is removed from the supports 2L and 2R by lifting the water stop plate 3B obliquely upward so that the operator pulls out the lock protrusion 32 from the lock hole 22.

  After removing the water stop plate 3B, the operation handle 42 of the lower release device 41 is operated in the same way as the release operation of the upper release device 41 for the left and right supports 2L and 2R to engage the water stop plate 3A. The engagement between the stop protrusion 32 head portion 32a and the head holding recess portion 30b of the head holding portion 30 is released (see FIG. 16B). Then, the water stop plate 3B is removed from the supports 2L and 2R by lifting the water stop plate 3B obliquely upward so that the operator pulls out the lock protrusion 32 from the lock hole 22.

  Also at this time, the head 32a of the locking projection 32 of the water stop plate 3A is configured to come into contact with the head slide surface 30a as in the case of the disengagement operation of the water stop plate 3B. The portion 32a can be prevented from being fitted again into the head holding recess 30b, and an accident or the like caused by the unexpected fall of the water stop plate 3A can be prevented.

  In this way, the operator can safely and easily remove the water stop plates 3A and 3B from the supports 2L and 2R alone. After the engagement between the head 32a of the locking projection 32 and the head holding recess 30b of the head holding part 30 is released, the operation handle 42 of the release device 41 is returned to the vertical position, and the action part 42 b is locked to the handle fixing member 44. Then, after the operation handle 42 of the upper and lower release devices 41 is returned to the vertical position, the cover portion 25 is closed.

  Next, another embodiment of the water stop device 1 will be described with reference to FIGS. In this embodiment, the shape of the head portion 32a of the locking projection 32 of the water stop plates 3A and 3B and the shape of the head holding recess portion 30b of the head holding portion 30 of the supports 2L and 2R are shown in FIGS. This is different from the above-described embodiment described with reference to FIG. Since the other configuration of this embodiment is the same as that of the above embodiment, detailed description thereof is omitted.

  As shown in FIG. 17, in the water blocking plate 3A, the head portion 32a of each locking projection 32 has a spherical shape. The diameter of the spherical head part 32a is larger than the left-right width dimension of the shaft part 32b. Note that FIG. 17 illustrates only the water stop plate 3A among the water stop plates 3A and 3B, but also in the water stop plate 3B, the head portion 32a of each locking projection 32 has a spherical shape.

  FIG. 18 shows a vertical cross-sectional view in the left-right direction when the support 2L is viewed from the back side (the cover portion 25 side). The pair of left and right head holding portions 30 provided for each of the two upper and lower locking holes 22 includes a head slide surface 30a and a head holding recess 30b. In the pair of left and right head holding portions 30, each head holding recessed portion 30b is provided in a corner portion of the head holding portion 30 that faces each other below the head slide surface 30a. The head holding recess 30b is formed by cutting out the corner, and has a shape obtained by substantially halving the concave spherical surface. The left and right head holding recesses 30b are formed symmetrically.

  As shown in FIG. 19, the water stop plates 3A and 3B of this embodiment are attached to and detached from the supports 2L and 2R in the same manner as in the above embodiment. In the state where the water stop plates 3A and 3B are attached to the supports 2L and 2R, the portions close to the shaft portion 32b of the spherical head portion 32a of the locking projection portion 32 are the head holding recess portions of the left and right head holding portions 30. It fits in 30b and is fixed.

  Further, when removing the water stop plates 3A, 3B from the supports 2L, 2R, as shown in FIG. 19, the operation handle 42 of the release device 41 is operated in the same manner as in the above embodiment, so that the spherical head The engagement between 32a and the substantially concave spherical head holding recess 30b is released.
