A middle portion of the operation handle 42 is rotatably supported by a base member 43 attached to the left and right inner side surfaces 24 . That is, when the operator pulls the grip portion 42a forward and rotates it downward, the action portion 42b rotates upward. A handle fixing member 44 is provided below the base member 43 so as to engage with the operating portion 42b of the operating handle 42 to fix the position of the operating handle 42. As shown in FIG.

In the support body 2L, the cover part 25 is provided so as to be openable and closable by means of a hinge member 45. As shown in FIG. In the closed state, the cover part 25 is non-rotatably fixed by a fixture such as a cylinder lock (not shown) or a magnet.

Next, referring to FIGS. 11 to 15, the operation of attaching the water stop plates 3A, 3B to the supports 2L, 2R will be described. 11 to 15, only the support 2L of the supports 2L and 2R is illustrated, but 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 arranged so as to face the supports 2L and 2R, the water stop plate 3A is slightly lifted, and the heads of the locking holes 22 below the supports 2L and 2R are opened. The head 32a of the locking protrusion 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 protrusion 32 of the water stop plate 3A is arranged at the same position on the standing surface portion 31 regardless of whether the water stop plate 3A is oriented vertically, horizontally, or longitudinally. Therefore, the operator who installs the water stop plate 3A can quickly insert the head portion 32a of the locking protrusion 32 into the head insertion hole 22a of the locking hole 22 without checking the orientation of the water stop plate 3A.

When the worker relaxes the force to lift the water stop plate 3A, the water stop plate 3A is displaced downward due to the weight of the water stop plate 3A, and the shaft portion 32b and the reinforcing rib 32d of the locking protrusion 32 move into the locking hole. 22 , and the head portion 32 a abuts on the head slide surface 30 a of the head holding portion 30 . Here, even if the shaft portion 32b and the reinforcing ribs 32d are laterally displaced with respect to the shaft portion insertion groove 22b when the head portion 32a is inserted into the head portion insertion hole 22a, the shaft portion 32b and the reinforcing ribs 32d are still in position. is guided to the shaft insertion groove 22b along the lower side 22c inclined downward toward the shaft insertion groove 22b. As a result, the shaft portion 32b and the reinforcing ribs 32d can be easily and reliably fitted into the shaft portion insertion grooves 22b. Also, the tip of the stopper protrusion 37 on the lower side of the water stop plate 3A is inserted into the stopper receiving recess 40 of the floor surface F. As shown in FIG.

When the water stop plate 3A is pushed downward so as to slide, the head portion 32a of the locking protrusion 32 moves along the head sliding surface 30a of the head holding portion 30 to attach the water stop plate to the supports 2L and 2R. It moves obliquely downward away from the surface portion 21 . At this time, the upright surface portion 31 of the water stop plate 3A is displaced so as to approach the water stop plate mounting surface portion 21, and the upright 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 slid further downward, the head portion 32a of the locking projection portion 32 reaches the head portion holding recessed portion 30b of the head portion holding portion 30, and the shaft of the head portion 32a is moved. A portion near the portion 32b is fitted into the head holding recess portion 30b (see also FIG. 11(C)). The head portion 32a is biased toward the head holding recess 30b by the restoring force of the upright surface portion packing member 33 made of an elastic body, and is held in the head holding recess 30b.

In this way, the water stop plate 3A is simply slid downward after the head portion 32a of the locking protrusion 32 of the water stop plate 3A is inserted into the head insertion hole 22a of the locking hole 22 of the support members 2L and 2R. With such 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 to prevent the water stop plate 3A from floating.

Further, in a state in which the head portion 32a of the locking projection portion 32 is fitted into the head holding recess portion 30b, the front-rear direction packing member 35 (see FIG. 3, etc.) and the horizontal surface portion packing member 36 on the lower side of the water stop plate 3A are It comes into close contact with the floor surface F and deforms under pressure. Thereby, high watertightness can be ensured between the water stop plate 3A and the floor surface F. In addition, since the tip side of the stopper protrusion 37 on the lower side of the water stop plate 3A is inserted into the stopper receiving recess 40 of the floor surface F, it is possible to reduce the bending of the water stop plate 3A due to the water pressure. It is possible to prevent deterioration of watertightness and breakage of the water stop plate 3A due to the curvature.

Subsequently, as shown in FIG. 14, the water stop plate 3B is arranged so as to face the supports 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 protrusion 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.

As with the water stop plate 3A, the water stop plate 3B has the locking protrusions 32 arranged at the same position on the standing surface portion 31 regardless of the orientation of the water stop plate 3B. Therefore, the operator who installs the water stop plate 3B can quickly insert the head portion 32a of the locking protrusion 32 into the head insertion hole 22a of the locking hole 22 without checking the orientation of the water stop plate 3B.

When the operator relaxes the force to lift the water stop plate 3B, the water stop plate 3B is displaced downward in the same manner as when the water stop plate 3A is attached, and the head portion 32a of the locking protrusion 32 moves into the head holding portion. 30 comes into contact with the head slide surface 30a. Also, while the tip of the stopper protrusion 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, the tip of the stopper protrusion 37 on the upper side of the water stop plate 3A It is inserted into the stopper receiving concave portion 38 on the lower side of the water stop plate 3B.

Then, when the water stop plate 3B is pushed downward to slide, the head portion 32a of the locking protrusion 32 slides 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 it moves obliquely 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. It is pressed and deformed together.

As shown in FIG. 15, when the water stop plate 3B is slid further downward, the head portion 32a of the locking protrusion 32 reaches the head holding recess portion 30b and stands up in the same manner as when the water stop plate 3A is attached. The head portion 32a is fitted into the head holding recess portion 30b by the restoring force of the surface portion packing member 33. As shown in FIG. After inserting the head portion 32a of the locking protrusion 32 of the water stop plate 3B into the head insertion hole 22a of the upper locking hole 22 of the support members 2L and 2R in this way, the water stop plate 3B is slid downward. With such a simple operation, the water stop plate 3B can be securely connected to the supports 2L and 2R, and the upward movement of the water stop plate 3B is restricted to prevent the water stop plate 3B from floating.

In addition, in a state in which the head portion 32a of the locking projection portion 32 of the water stop plate 3B is fitted into the head holding recess portion 30b, the front-rear direction packing member 35 and the horizontal surface portion packing member 36 on the lower side of the water stop plate 3B, The longitudinal packing member 35 and the horizontal packing member 36 on the upper side of the water stop plate 3A come into contact with each other and are pressed and deformed. Thereby, high watertightness can be secured between the water stop plate 3A and the water stop plate 3B.

Further, the tip side of the stopper protrusion 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 tip side of the stopper protrusion 37 on the upper side of the water stop plate 3A It is inserted into the stopper receiving recess 38 on the lower side of the plate 3B. As a result, it is possible to reduce the bending of the water stop plates 3A and 3B caused by the water pressure, and prevent the deterioration of the watertightness and the breakage of the water stop plate 3A caused by the bending of the water stop plates 3A and 3B.

Next, referring to FIG. 16, the operation of removing the water stop plates 3A, 3B attached to the supports 2L, 2R will be described. Although FIG. 16 shows the support 2L of the supports 2L and 2R, since the supports 2L and 2R are provided symmetrically as described above, the support 2R can also be removed in the same manner. will be

Grasp the grip portion 42a of the operation handle 42 of the upper release device 41 of the two upper and lower release devices 41, pull the grip portion 42a forward (opposite side to the waterstop mounting surface portion 21), and rotate downward. As the grip portion 42 a rotates downward, the action portion 42 b of the operating handle 42 rotates upward and is disengaged from the handle fixing member 44 .

When the gripping portion 42a is further rotated downward, the action portion 42b is further rotated upward, contacts the head portion 32a of the locking projection portion 32 of the water stop plate 3B from below, and pushes up the head portion 32a. The head portion 32a is disengaged from the head holding recess 30b of the head holding portion 30 and moved to the lower end portion of the head slide surface 30a. The engagement with the recess 30b is released (see FIG. 16(A)).

In a state in which the engagement between the head portion 32a and the head holding recessed portion 30b is released, the head portion 32a of the locking projection portion 32 is positioned between the standing surface portion packing member 33 between the standing surface portion 31 and the waterstop mounting surface portion 21. is pressed against the head slide surface 30a by the restoring force of . As a result, even if the operating portion 42b of the operating handle 42 is separated from the head portion 32a of the locking protrusion 32, the head portion 32a is not re-engaged in the head portion holding recess portion 30b of the head portion holding portion 30. there is

Further, when the engagement between the head portion 32a and the head holding recess portion 30b is released, the head portion 32a of the locking projection portion 32 is brought into contact with the head slide surface 30a of the head holding portion 30. The head 32a is configured so as not to slip out of the locking hole 22. As a result, when the operator operates the operating handle 42, the water stop plate 3B can be prevented from being unexpectedly detached from the supports 2L and 2R, thereby preventing accidents caused by the water stop plate 3B dropping or falling. While being able to improve the safety of water stop plate removal work, damage to the water stop plate 3B can be prevented.

The operator operates the operation handle 42 of the upper releasing device 41 for the left and right supports 2L, 2R to hold the head portion 32a of the locking projection 32 of the water stop plate 3B and the head portion of the head holding portion 30. 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 as to pull out the locking projections 32 from the locking holes 22 .

After removing the water stop plate 3B, the operation handle 42 of the lower release device 41 is operated in the same manner 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 head portion 32a of the stop projection portion 32 and the head holding recess portion 30b of the head holding portion 30 is released (see FIG. 16(B)). Then, the water stop plate 3B is removed from the supports 2L and 2R by lifting the water stop plate 3B obliquely upward so as to pull out the locking projections 32 from the locking holes 22 by the operator.

At this time as well, the head portion 32a of the locking protrusion 32 of the water stop plate 3A is configured to come into contact with the head slide surface 30a in the same manner as in the disengagement operation of the water stop plate 3B. It is possible to prevent the portion 32a from re-engagement in the head holding recessed portion 30b, and to prevent an accident or the like caused by an unexpected fall of the water stop plate 3A.

Thus, the operator can safely and easily remove the water stop plates 3A, 3B from the supports 2L, 2R by himself. After the engagement between the head portion 32a of the locking projection portion 32 and the head holding recess portion 30b of the head holding portion 30 is released, the operating handle 42 of the release device 41 is returned to the vertical position, and the operating portion 42 b is locked to the handle fixing member 44 .
