A portion close to the portion 32b is fitted into the head holding concave portion 30b (see also FIG. 26(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.

In addition, 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 packing member 35 (see FIG. 18, etc.) and the horizontal surface portion packing member 136 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. The horizontal surface portion packing member 136 displaces the tip of the water stop material 136a forward and backward along the floor surface F in the same manner as the operation described with reference to FIGS. and foreign matter S such as pebbles are removed from below the water stop plate 3A. As a result, foreign matter can be prevented from being caught between the water stop material 136a and the floor surface F, and 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 floor surface 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 of 3A.

Subsequently, as shown in FIG. 29, 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 heads 32a of the locking protrusions 32 of the water stop plate 3B are inserted into the head insertion holes 22a of the locking holes 22 on the upper sides 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 worker relaxes the force to lift the water stop plate 3B, the water stop plate 3B is displaced downward as in the case of installing the water stop plate 3A, and the head portion 32a of the locking projection portion 32 moves to 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. 30, 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 reliably connected to the supports 2L and 2R, and the upward movement of the water stop plate 3B is regulated to prevent the water stop plate 3B from floating.

Further, 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 packing member 35 and the horizontal surface portion packing member 136 on the lower side of the water stop plate 3B, The front-rear packing member 35 and the horizontal surface packing member 136 on the upper side of the water stop plate 3A are in close contact with each other and deformed under pressure in the same manner as in the state shown in FIG. 15(D). 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. 31, the operation of removing the water stop plates 3A, 3B attached to the supports 2L, 2R will be described. Of the supports 2L and 2R, only the support 2L is shown in FIG. 31, but 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

First, the cover portion 25 of the support 2L is opened to make the releasing device 41 operable. 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. 31(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 action 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 operating 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. 31(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 that the locking projection 32 is pulled out from the locking hole 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 contact the head slide surface 30a, as in the case of 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 . After the operating handles 42 of the upper and lower releasing devices 41 are 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. 32 to 34. FIG. In this embodiment, the shape of the head portions 32a of the locking projections 32 of the water stop plates 3A, 3B and the shape of the head holding recesses 30b of the head holding portions 30 of the supports 2L, 2R are shown in FIGS. This differs from the above embodiment described with reference to FIG. Since other configurations of this embodiment are the same as those of the above-described embodiment, detailed description thereof will be omitted.

As shown in FIG. 32, in the water stop plate 3A, the head 32a of each locking protrusion 32 has a spherical shape. The diameter of the spherical head portion 32a is larger than the lateral width dimension of the shaft portion 32b. Although FIG. 32 shows only the water stop plate 3A out of the water stop plates 3A and 3B, the head portion 32a of each locking protrusion 32 also has a spherical shape in the water stop plate 3B.

FIG. 33 shows a vertical cross-sectional view in the left-right direction of the support 2L as seen from the rear side (cover portion 25 side). A pair of left and right head holding portions 30 provided for each of the 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, the respective head holding recesses 30b are provided at the corners of the head holding portions 30 facing each other below the head slide surface 30a. The head holding concave portion 30b is formed by notching the corner portion, and has a shape obtained by dividing a concave spherical surface in half. The left and right head holding recesses 30b are formed symmetrically.

As shown in FIG. 34, water stop plates 3A and 3B of this embodiment are attached to and detached from supports 2L and 2R in the same manner as in the above embodiment. When the water stop plates 3A and 3B are attached to the supports 2L and 2R, the portions of the spherical head portion 32a of the locking protrusion 32 near the shaft portion 32b are aligned with the head holding recesses of the left and right head holding portions 30. 30b and fixed.

When removing the water stop plates 3A, 3B from the supports 2L, 2R, as shown in FIG. 32a is disengaged from the generally concave spherical head holding recess 30b.

The present invention is not limited to the above-described embodiments, and can be embodied in various aspects. For example, the pair of left and right stopper protrusions 37 in the water stop plate 3B may be configured such that only one of the stopper protrusions 37 is provided.

Further, in the present invention, the number of water stop plates attached to the left and right supports is not limited to two, and may be one or three or more.

In addition, the configuration in which the packing member provided on the horizontal surface portion (lower surface) below the water stop plate and in close contact with the floor surface is curved toward the front and back outside is applicable not only to the water stop device of the above embodiment, It can be applied to a water stop device in which a water stop plate is moved downward from above. Such a packing member can be applied to, for example, a water stop device (see, for example, Patent Document 1) in which a water stop plate is installed by dropping the water stop plate from above into a facing groove provided in a support. be. Moreover, such a packing member can also be applied to a water stop device in which the water stop plate is oriented vertically or anteroposteriorly.

By the way, in the configuration in which the vertically extending packing member provided on the standing surface of the water stop plate is pressed forward and backward against the water stop plate mounting surface portion of the support, the lower end of the packing member There is a possibility that it will not adhere sufficiently to the corner where the lower end of the plate mounting surface and the floor intersect. Since such insufficient adhesion may cause water leakage at the corners, it is preferable to ensure sufficient watertightness at the corners.

An embodiment capable of resolving such concerns will be described with reference to FIGS. 35 to 41. FIG. In FIGS. 35 to 41, portions having the same functions as those of the embodiment described with reference to FIGS. 1 to 15 are denoted by the same reference numerals.

As shown in FIGS. 35 and 36, the water stop device 101C of the present embodiment is detachably attached to the left and right supports 102CL and 102CR and the left and right supports 102CL and 102CR which are spaced apart. 103 C of standing water stop plates are provided. The supports 102CL and 102CR are provided with corner members 126 and 126 arranged on the floor surface F continuously from their lower ends.

As shown in FIGS. 37 and 38, the front and rear upright surface portions of the water stop plate 103C are divided into an indoor upright surface portion 131I arranged facing indoors and an outdoor upright surface portion 131O arranged facing outdoors. ing. In the water stop plate 103C, upper and lower corners 151 where the indoor-side upright surface portion 131I and the upper and lower horizontal surface portions 134 intersect are rounded. Upper and lower corners where the outdoor standing surface portion 131O and the upper and lower horizontal surface portions 134 intersect are formed substantially at right angles.

Each of the upper and lower horizontal surface portions 134, 134 is provided with a horizontal surface portion packing member 136 formed of an elastic body extending in the left-right direction. The horizontal surface portion packing member 136 is formed of a single elastic body extending in the left-right direction, and is arranged in a region of the horizontal surface portion 134 near the outdoor side upright surface portion 131O.

Upright surface portion packing members 133 formed of an elastic body extending in the vertical direction are provided at the left and right width direction end portions 131a, 131a of the indoor side upright surface portion 131I. Each upright surface packing member 133 is formed of one elastic body extending in the left-right direction. On the other hand, the standing surface portion packing member 133 is not provided on the outdoor side standing surface portion 131O. That is, the water stop plate 103C is provided with two upright surface portion packing members 133 .

A longitudinal packing member 135 is provided at each of the left and right width direction end portions of the upper and lower horizontal surface portions 134 . Each front-rear packing member 135 is formed of one elastic body extending in the front-rear direction.

The upper and lower longitudinal ends 133e of the upright surface packing member 133 are continuous with the ends of the front-rear packing member 135 on the indoor upright surface 131I side via the corners 151 from the indoor upright surface 131I. That is, the water stop plate 103C is provided with packing members (upright surface portion packing member 133 and front-back direction packing member 135) extending from the indoor side upright surface portion 131I to the horizontal surface portion 134 via the corner portion 151. As shown in FIG. Both left and right end portions of the horizontal surface portion packing member 136 are connected to the left and right front-rear direction packing members 135 without gaps.

Other configurations of the water stop plate 103C in the water stop device 101C of this embodiment are the same as those of the water stop plate 103A in the water stop device 101 described with reference to FIGS.

Next, configurations of the supports 102CL and 102CR and the corner member 126 will be described with reference to FIGS. 35, 36, 39 and 40. FIG. The supports 102CL and 102CR project the waterstop plate mounting surface portion 121 from the middle portion of the projection holding portion 122 to the left and right inwards in the same manner as the supports 102L and 102R of the water stop device 101 (see FIGS. 8 and 9). It has a substantially T-shaped columnar shape in plan view. The supports 102CL and 102CR have bilaterally symmetrical configurations.

Each of the projection holding portions 122 of the supports 102CL and 102CR is provided with a pair of upper and lower locking grooves 123 and 124 . The support bodies 102CL and 102CR are not provided with the guide portion 125 (see FIGS. 8 and 9, etc.). The vertical opening dimension of the opening portion 123a of the lower locking groove 123 is formed to be larger than the groove width dimension of the projection holding portion 123c. This makes it easier to insert the locking protrusion 132 of the water stop plate 103C from the front side (outdoor side) toward the back side (indoor side).

In the supports 102CL and 102CR, a corner member 126 projecting to the outside is connected to the lower end of the side surface 121a of the waterproof plate mounting surface portion 121 facing the outside. The corner member 126 is made of metal or resin, for example, and has the shape of a substantially right-angled triangular prism extending in the horizontal direction of a substantially right-angled triangular vertical cross section. It is connected to the lower end and the other is arranged on the floor surface F. In addition, the inclined surface 126a (oblique side) of the corner member 126 is formed in a concave curved inclined shape, and is disposed obliquely downward toward the floor surface F from the outdoor side surface 121a. In this manner, the corner member 126 is disposed at the corner where the outdoor side surface 121a of the waterstop mounting surface portion 121 and the floor surface F intersect. A water stop material (for example, an adhesive or an elastic body) (not shown) is provided between the corner member 126, the outdoor side surface 121a, and the floor surface F. Watertightness between F and F is ensured.

In the water stop device 101C, when the water stop plate 103C is attached to the supports 102CL and 102CR, the water stop plate 103C is arranged with the indoor side upright surface portion 131I of the water stop plate 103C directed toward the indoor side, as shown in FIGS. 11 is performed to attach the water stop plate 103A to the supports 102L and 102R. The corner 151 of the water stop plate 103C is rounded, and the longitudinal end 133e of the upright surface packing member 133 arranged on the surface of the corner 151 is also rounded. In a process similar to that shown, the contact area between the upright surface packing member 133 and the outdoor side surface 121a can be reduced, and unnecessary deformation of the upright surface packing member 133 during the mounting process and the accompanying damage and deterioration can be reduced. The operation of attaching the water stop plate 103C to the bodies 102CL and 102CR can be performed smoothly.

As shown in FIG. 41, when the water stop plate 103C is completely attached to the supports 102CL and 102CR, the lower horizontal surface portion 134 is arranged to face the floor surface F, and the width direction end of the indoor side upright surface portion 131I is arranged to face the floor surface F. The portion 131a is arranged to face the water stop plate mounting surface portion 121 of the supports 121CL and 102CR, and the corner portion 151 is arranged to face the corner member 126. As shown in FIG. The lower horizontal surface packing member 136 is in close contact with the floor surface F, the upright surface packing member 133 is in close contact with the outdoor side surface 121a of the waterstop mounting surface 121, and the length of the lower side of the upright surface packing member 133 The longitudinal end portion 133 e comes into close contact with the inclined surface 126 a of the corner member 126 . This ensures watertightness between the water stop plate 103C, the supports 102CL, 102CR, and the floor surface F. Since the lower end of the upright surface packing member 133 is in close contact with the corner member 126 provided at the corner where the lower end of the water stop plate mounting surface 121 of the supports 102CL and 102CR and the floor surface F intersect, the corner is Sufficient watertightness can be secured in

Further, in this embodiment, since the water stop plate 103C has a vertically symmetrical shape, it is necessary to check the vertical direction of the water stop plate 103C when attaching the water stop plate 103C to the supports 102CR and 102CL. In addition to eliminating the need for a water stop plate 103C, mistakes in the vertical installation direction can be eliminated, and the water stop plate 103C can be quickly and accurately attached to the supports 102CR and 102CL.

In the water stop plate 103C, at least the lower corners 151 of the upper and lower corners 151 where the indoor side upright surface portion 131I and the upper and lower horizontal surface portions 134 intersect are rounded, and the indoor side upright surface portion 131I from the lower corner 151 to the lower horizontal surface portion 134 (the upright surface packing member 133 and the front-rear direction packing member 135). Since the lengthwise end portion 133e is in close contact with the corner member 126 disposed at the corner portion where the lower end of the water stop plate mounting surface portion 121 of the supports 102CL and 102CR and the floor surface F intersect, the corner portion is sufficiently watertight. can ensure the integrity of

For example, in 103 C of water stop plates shown in FIG.37 and FIG.38, the upper corner|angular part 151 does not need to be rounded. In this case, the upper front-rear packing member 135 and the upper horizontal surface packing member 136 may not be provided.

In addition, the front portions of the four corners where the upright surface portions 131I and 131O intersect with the upper and lower horizontal surface portions 134 are rounded, and the packing members (upright A surface packing member 133 and a longitudinal packing member 135) may be provided. In this case, there is no distinction between the standing surface portions 131I and 131O, and the task of confirming the direction of the waterstop plate is no longer required, similar to the waterstop plate 103A described with reference to FIGS. 10 and 11 . The horizontal surface portion packing member 136 is provided to extend in the horizontal direction on the horizontal surface portion 134 between the front and rear corner portions.

The packing members 133, 135, and 136 of the water stop plate 103A (see FIG. 4, etc.) can also be applied as the packing members 133, 135, and 136 of the water stop plate 103C.

Further, in the supports 102CL and 102CR, the corner member 126 may be integrally formed with the water stop plate mounting surface portion 121. As shown in FIG. Also, the inclined surface 126a of the corner member 126 may be formed as a flat surface. Also, the material of the corner member 126 is not particularly limited, and may be metal, resin, elastic material (rubber), or the like. For example, the corner member 126 is applied to a corner portion where the floor surface F intersects with the outdoor side surface 121a of the water stop plate mounting surface portion 121 of the support members 102CL and 102CR after the support members 102CL and 102CR are installed on the floor surface F. It may be made of an elastic waterproofing agent (for example, a caulking agent).

Note that elastic corner members 126 are arranged on the supports 102L and 102R of the water stop device 101 described with reference to FIGS. By elastically deforming the corner member 126 when attached, it is possible to improve the watertightness at the corner portion where the outdoor side surface 121a of the water stop plate attachment surface portion 121 of the supports 102L and 102R and the floor surface F intersect. can.

In the supports 102CR and 102CL, as shown in FIG. 42, the opening portions 123a and 124a of the locking grooves 123 and 124 are larger than the outer diameter of the locking protrusion 132 of the water stop plate 103C. Alternatively, the inclined portions 123b and 124b may be tapered toward the protrusion holding portions 123c and 124c. This facilitates the operation of inserting the locking protrusion 132 into the locking grooves 123 and 124 when attaching the water stop plate 103c to the supports 102CR and 102CL. Further, in this modified example, the openings 124a of the upper locking grooves 124 are open to the upper end surfaces and the outdoor end surfaces 122b of the projection holding portions 122 of the supports 102CR and 102CL. The insertion operation of the locking protrusion 132 is further facilitated.

The shape of the locking grooves 123 and 124 shown in FIG. 42 can be applied to the locking grooves 123 and 124 of the supports 102L and 102R of the water stop device 101 described with reference to FIGS. 1 to 15. Needless to say.

This embodiment comprises left and right supports 102CR and 102CL spaced apart, and a water stop plate 103C detachably attached to the left and right supports 102CR and 102CL. In the apparatus 101C, the water stop plate 103C has a rounded corner 151 where the indoor-side upright surface portion 131I and the lower horizontal surface portion 134 intersect. Packing members 133 and 135 extending from the upright surface portion 131I to the horizontal surface portion 134 via the corner portion 151 are provided at a width direction end portion 131a of the upright surface portion 131I arranged to face the mounting surface portion 121, and the supports 102CR and 102CL are provided. A corner member 126 is disposed at a corner portion where the lower end of the water stop plate mounting surface portion 121 and the floor surface F intersect, and the water stop plate 103C is directed toward the water stop plate mounting surface portion 121 and the floor surface F The packing members 133 and 135 are attached to the supports 102CR and 102CL in an urged state, and the packing members 133 and 135 are in close contact with the water stop plate attachment surface portion 121, the corner member 126 and the floor surface F.
