The present invention relates to a shutter device with a waterstop.

Conventionally, shutters equipped with waterstops are well known. For example, Patent Document 1 discloses a shutter equipped with a waterstop, in which a waterstop is provided at the bottom of the slat door body.

JP 2013-159911 A

However, when a load is applied to the shutter with a water stop from the indoor side toward the outdoor side, it is difficult to hold the shutter with a water stop to the structure.

The present invention was made in consideration of the above circumstances, and aims to provide a shutter device with a water stop that can hold the shutter against a structure when a load directed toward the outdoors is input to the shutter.

The shutter device with a waterstop of the present invention comprises a shutter curtain, a waterstop connected to the shutter curtain, a holding member attached to the waterstop that can hold the waterstop against a structure when a load directed toward the outdoors is input to the waterstop, and a floor of the structure that has an engaged portion that can engage with an engaging portion of the holding member to hold the waterstop.

Conventionally, when a load from the indoor side to the outdoor side is applied to a waterstop due to strong winds or other factors, the waterstop can bend, creating a gap between the waterstop and the floor, potentially reducing its watertightness. However, because the waterstop of the present invention is held to the structure via a retaining member, deflection of the waterstop is suppressed. Therefore, even when a load is applied to the waterstop in the outdoor direction, gaps are less likely to form between the waterstop and the floor of the structure, reducing the reduction in watertightness.

The retaining member is provided on the indoor side of the waterstop.

In the shutter device with waterstop, compared to when the retaining member is located on the outdoor side of the waterstop, the present invention can more effectively suppress deflection of the waterstop when a load is applied to the waterstop from the indoor side toward the outdoor side.

The retaining member is located in the center of the waterstop in the left-right direction.

In the shutter device with waterstop, compared to when the retaining members are provided at the left and right ends of the waterstop, the present invention is able to more effectively suppress the overall deflection of the waterstop when a load is applied to the waterstop from the indoor side toward the outdoor side.

The holding member has a columnar member that extends and is movable in the vertical direction, and the engaged portion is a recess provided on the floor into which the engaging portion at the lower end of the columnar member can be inserted.

In the shutter device with waterstop, the waterstop can be held against the structure by the simple action of moving the column-shaped member downward and inserting it into the recess.

The engagement portion at the lower end of the columnar member has a tapered portion that narrows downward.

In the shutter device with waterstop, even if the position of the pillar-shaped member is misaligned with respect to the recess, the tapered portion will hit the corner of the recess, causing the pillar-shaped member to move and be inserted into the recess.

The holding member has a biasing member that biases the columnar member downward.

In the shutter device with waterstop, even if the engaging portion of the holding member is misaligned from the engaged portion, the biasing member presses the columnar member downward, so the engaging portion of the columnar member is guided toward and inserted into the engaged portion.

In the shutter device with waterstop according to the present invention, the waterstop is held to the structure via a retaining member, so when a load is applied to the waterstop from the indoor side to the outdoor side, deflection of the waterstop is suppressed, reducing the deterioration of watertightness.

[First embodiment]
The present embodiment relates to a shutter device with a waterstop 1. Fig. 1 is a front view showing a shutter device with a waterstop 1 according to a first embodiment.

As shown in FIG. 1 , the structure 10 has a wall 11 installed on a floor 13, and an opening 12 is provided in the wall 11. In this embodiment, the structure 10 is, for example, a house, but other structures 10 include buildings, warehouses, factories, etc. In this embodiment, the wall 11 is an exterior wall that separates the inside and outside of the structure 10, but other walls include, for example, interior walls that separate the internal space within the structure 10. The opening 12 is provided in the wall 11 of the structure 10 and connects the indoor and outdoor sides of the structure 10 in the internal and external directions.

A pair of left and right guide rails 20 are provided around the periphery of the opening 12. Specifically, each guide rail 20 extends in the vertical direction. The right guide rail 20A and the left guide rail 20B are located apart by the width of the waterstop shutter 100. The outdoor side refers to the outside of the structure 10, and is the upstream side of water intrusion during flooding, i.e., the side that water reaches first. The indoor side refers to the inside of the structure 10, opposite the outdoor side.

The shutter with waterstop 100 comprises a winding mechanism 40 provided in the shutter case 30 located at the upper end, a shutter curtain 50 extending downward from the winding mechanism 40, and a first waterstop 60 connected to the lower end of the shutter curtain 50.

The retraction mechanism 40 has a shaft 41 and a rotating drum 42. The shaft 41 extends in the left-right direction, and both left and right ends are rotatably supported by supports 43. The shaft 41 is driven to rotate by a motor (not shown). The rotating drum 42 is attached to the shaft 41 and rotates integrally with the shaft 41. Figure 1 shows the shutter in the closed position, but when the rotating drum 42 rotates and the shutter curtain 50 is retracted around the outer periphery of the rotating drum 42, the first water stop plate 60 rises and the shutter moves to the open position.

The shutter curtain 50 consists of multiple slats 51 that are interconnected and extend vertically. Each slat 51 is a horizontally elongated plate that extends horizontally and is made of, for example, a steel plate, a stainless steel plate, or an aluminum plate. A first waterstop 60 is connected to the lowest slat 51.

Figure 2 is a schematic and illustrative cross-sectional view taken along line II-II in Figure 1. Figure 3 is an enlarged view showing the first stopper pin 70 and the first support plate 80 provided on the floor 13 in Figure 2.

As shown in Figures 1 and 2, a handle 61 (grip) is provided on the indoor side of the lower part of the first water stop 60. The handle 61 has a U-shape when viewed from the side. Specifically, the handle 61 has an upper leg 62 located on the upper side and extending toward the indoor side, a side leg 63 extending downward from the tip of the upper leg 62, and a lower leg 64 extending toward the outdoor side from the bottom end of the side leg 63. The first water stop 60 can be swung back and forth by grasping the handle 61 and pulling it toward the indoor side or pushing it toward the outdoor side. In addition, a fixed plate 65 extends from the indoor side surface of the first water stop 60 toward the indoor side, and a first stopper pin 70 (a pillar-shaped member, a retaining member) is provided on the side of the fixed plate 65. In this way, the first stopper pin 70 is provided on the indoor side of the first water stop 60. Additionally, the dashed dotted line CL shown in Figure 1 extends vertically through the left-right center of the first waterstop 60. Therefore, the first stopper pin 70 is located in the left-right center of the first waterstop 60.

As shown in Figures 2 and 3, the first stopper pin 70 (columnar member, holding member) extends vertically and is movable in the vertical direction. This is explained in detail below.

The first stopper pin 70 has a base 71 and an engaging member 72. The base 71 is cylindrical with a closed upper end and has a vertically extending recessed groove 73 formed therein. The engaging member 72 has a slide shaft portion 74, a cylindrical portion 75, and a first engaging portion 76 (engaging portion). The slide shaft portion 74 is configured to be able to move vertically within the recessed groove 73. The cylindrical portion 75 extends downward from the slide shaft portion 74. The first engaging portion 76 is provided at the lower end of the cylindrical portion 75 and has a curved, spherical bottom surface 77. The slide shaft portion 74, cylindrical portion 75, and first engaging portion 76 are integrally configured. In addition, a spring 78 (biasing member) is provided between the lower end surface 71a of the base 71 and the upper end surface 75a of the cylindrical portion 75, spirally surrounding the outer periphery of the slide shaft portion 74. Therefore, the engaging member 72 is elastically pressed downward by the biasing force of the spring 78.

As shown in FIG. 2, the first support plate 80 has a flat plate portion 81, an inner vertical wall 82 extending downward from the indoor-side edge of the flat plate portion 81, and an outer vertical wall 83 extending downward from the outdoor-side edge of the flat plate portion 81. As shown in FIG. 3, the flat plate portion 81 has a curved portion 84 that is spherically concave downward. A first recess 85 (engaged portion) is provided in the curved portion, and the first engaging portion 76 of the first stopper pin 70 fits into the first recess 85, thereby engaging the first engaging portion 76 (engaging portion) with the first recess 85 (engaged portion). This allows the first water stop 60 to be held against the floor 13.

FIG. 4 is a schematic and exemplary side view showing the vicinity of the upper end portion of the first waterstop 60. As shown in FIG.
As shown in Figure 4, each slat 51 has curved curled portions 51a, 51b at its upper and lower ends. Slats 51 adjacent to each other in the vertical direction are connected by engaging their respective curled portions 51a, 51b. This forms a shutter curtain 50 extending in the vertical direction. A first waterstop 60 is connected to the lowest slat 51. This will be described in detail below.

The upper end of the first waterstop 60 has a flat upper surface 67 extending inward and outward on the outdoor side, and an upper flange 68 extending upward on the indoor side. The outdoor-facing side of the upper flange 68 is flat, and the slat 51 is pressed against the flat surface and connected to the upper flange 68 with bolts 86 and nuts 87. The slat 51 and the upper flange 68 have a number of through holes spaced equally apart along the left-right direction (the front-to-back direction of the paper in Figure 4). When the through holes in the slat 51 and the upper flange 68 are aligned so that they match, and the threaded portion 86a of the bolt 86 is inserted through the through hole from the outdoor side to the indoor side, the threaded portion 86a protrudes from the indoor side of the upper flange 68. The slat 51 is fastened (connected) to the first waterstop 60 by tightening a nut 87 onto the threaded portion 86a from the indoor side. These bolts 86 and nuts 87 are provided at equal intervals in multiple locations along the left-right direction of the upper flange 68 (the front-to-back direction of the paper in Figure 4). A cover 90 that covers the outdoor side of the bolts 86 is provided on the first waterstop 60. This cover 90 is L-shaped in side view and has a vertical wall portion 91 extending upward from the top surface of the first waterstop 60 and a horizontal wall portion 92 extending from the upper end of the vertical wall portion 91 toward the indoor side. The cover 90 can be attached to the first waterstop 60 via connecting members such as bolts, but is configured so that it can only be removed using a dedicated tool or from the indoor side.

FIG. 5 is a perspective view showing a second support plate according to a modified example of the first embodiment.
As shown in Figure 5, the second support plate 180 has a flat plate portion 181, an inner vertical wall 182 extending downward from the indoor-side edge of the flat plate portion 181, and an outer vertical wall 183 extending downward from the outdoor-side edge of the flat plate portion 181. The flat plate portion 181 has a circular through-hole 184. A tubular member 186 is inserted into the through-hole 184. The tubular member 186 has an annular flange portion 187, a cylindrical side portion 188 extending downward from the flange portion, and a bottom portion 189 sealing the lower end of the side portion. The flange portion 187, side portion 188, and bottom portion 189 are integrally formed. Further, second recesses 185 (engaged portions) are provided in the side portions 188 and the bottom portion 189, and the first engaging portions 76 of the first stopper pin 70 enter the second recesses 185, thereby engaging the first engaging portions 76 (engaging portions) with the second recesses 185 (engaged portions). This allows the first water stop 60 to be held against the floor 13.

As described above, the shutter device 1 with a waterstop according to this embodiment comprises a shutter curtain 50, a first waterstop 60 (waterstop) connected to the shutter curtain 50, a first stopper pin 70 (retaining member) provided on the first waterstop 60, and a floor 13 of a structure 10 provided with a first recess 85 (engaged portion) that can engage with the first engaging portion 76 (engaging portion) of the first stopper pin 70 to hold the first waterstop 60. The first stopper pin 70 is configured to be able to hold the first waterstop 60 against the structure 10 when a load directed toward the outdoors is input to the first waterstop 60.

Conventionally, when a load from the indoor side to the outdoor side is applied to a water stop due to strong winds or the like, the water stop can bend, creating a gap between the water stop and the floor, potentially resulting in a decrease in watertightness. In this embodiment, the first water stop 60 is held to the structure 10 via the first stopper pin 70, thereby preventing the first water stop 60 from bending. Therefore, even when a load is applied to the first water stop 60 in the outdoor direction, a gap is less likely to form between the first water stop 60 and the floor 13, preventing a decrease in watertightness. In particular, if a watertight rubber (not shown) is attached to the lower end surface of the first water stop 60, the watertight rubber is less likely to peel off, preventing a decrease in watertightness between the first water stop 60 and the floor.

The first stopper pin 70 (retaining member) is located on the indoor side of the first waterstop 60 (waterstop). Therefore, compared to when the first stopper pin 70 is located on the outdoor side of the first waterstop 60, this embodiment can more effectively suppress deflection of the first waterstop 60 when a load is applied to the first waterstop 60 from the indoor side toward the outdoor side.

The first stopper pin 70 (retaining member) is located in the left-right center of the first waterstop 60 (waterstop). Therefore, compared to when the first stopper pin 70 is located at the left-right end of the first waterstop 60, this embodiment can more effectively suppress deflection of the first waterstop 60 when a load is applied to the first waterstop 60 from the indoor side toward the outdoor side.

The first stopper pin 70 (holding member) has a columnar member that extends and is movable in the vertical direction, and the first recess 85 (engaged portion) is a recess that is provided in the floor 13 and into which the first engaging portion 76 (engaging portion) at the lower end of the first stopper pin 70 can be inserted. In this way, the first waterstop 60 can be held to the structure 10 by the simple action of moving the first stopper pin 70 downward and inserting it into the first recess 85.

The first stopper pin 70 (retaining member) has a spring 78 (biasing member) that biases the columnar member downward. Therefore, even if the first engagement portion 76 of the first stopper pin 70 is positioned away from the first recess 85, the spring 78 presses the first engagement portion 76 downward, so that the first engagement portion 76 of the first stopper pin 70 is guided toward and inserted into the first recess 85.

In the past, for example, the slats 51 were welded to the first waterstop 60 or crimped to connect them to the first waterstop 60, making it difficult to remove the waterstop from the slats for maintenance, etc. However, in this embodiment, as explained using Figure 4, the slats 51 are connected to the upper flange 68 of the first waterstop 60 via bolts 86 and nuts 87. This makes it easy to remove the first waterstop 60 from the slats 51 for maintenance, etc.

Furthermore, in this embodiment, as explained using Figure 4, the outdoor side of the bolt 86 is covered with a cover 90, making it difficult to remove the bolt 86 from the outdoor side, improving security, and since the bolt 86 is not visible, the exterior appearance is improved.

Furthermore, as explained using Figure 5, the second recess 185 (engaged portion) is provided in a cylindrical member 186 that is separate from the flat plate portion 181, so the depth of the second recess 185 can be increased.

Second Embodiment
Next, a second embodiment will be described, in which the same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Figure 6 is a schematic and illustrative cross-sectional view showing the second stopper pin 170 and third support plate 280 according to the second embodiment.

The second stopper pin 170 (columnar member, holding member) extends vertically and is configured to be movable in the vertical direction. Details are explained below.

The second stopper pin 170 has a base 171 that extends vertically and a second engagement portion 172 that protrudes downward from the base 171. The base 171 and second engagement portion 172 are integrally formed. The bottom surface 172a of the second engagement portion 172 is inclined obliquely downward as it approaches the indoor side in side view. In other words, the second engagement portion 172 at the lower end of the second stopper pin 170 (columnar member, holding member) has a tapered portion 173 that tapers downward.

The third support plate 280 has a flat plate portion 281, which has a third recess 285 (engaged portion) that is recessed downward. Specifically, the third recess 285 is composed of an outer side wall portion 283, an inner side wall portion 284, and a bottom wall portion 286. The outer side wall portion 283 extends downward from the flat plate portion, and the inner side wall portion 284 extends downward from the outer side wall portion 283 toward the indoor side at a distance. The bottom wall portion 286 connects the lower end 283a of the outer side wall portion 283 with the lower end 284a of the inner side wall portion 284, and is inclined obliquely downward so as to extend downward toward the indoor side in side view. The second engaging portion 172 of the second stopper pin 170 enters the third recess 285, thereby engaging the second engaging portion 172 (engaging portion) with the third recess 285 (engaged portion).

Even if the position of the second stopper pin 170 shifts inward or outward relative to the third recess 285, as shown by the dotted line in Figure 6, the bottom surface 172a of the second stopper pin 170 will abut against the corner 283b of the outer side wall portion 283, and the second stopper pin 170 will slide toward the indoor side as shown by the arrow and be inserted into the third recess 285.

As explained above, in this embodiment, the second engagement portion 172 provided at the lower end of the second stopper pin 170 (columnar member, holding member) has a tapered portion 173 that tapers downward. Therefore, even if the position of the second stopper pin 170 shifts inward or outward relative to the third recess 285, the second stopper pin 170 moves and is inserted into the third recess 285.

[Third embodiment]
Next, a third embodiment will be described, with the same components as those in the first and second embodiments being designated by the same reference numerals and the description thereof being omitted.

Figure 7 is a schematic and exemplary front view of the second waterstop 160 according to the third embodiment, viewed from the outdoor side. Figure 8 is a schematic and exemplary side view of the second waterstop 160 shown in Figure 7, viewed from the side.

As shown in Figures 7 and 8, the second waterstop 160 has a base 167, a first guide 161, a second guide 162, a third guide 163, a fourth guide 164, a fifth guide 165, and a sixth guide 166. The base 167, the first guide 161, the second guide 162, the third guide 163, the fourth guide 164, the fifth guide 165, and the sixth guide 166 are all joined together.

The base 167 is a plate-like member having a rectangular shape when viewed from the inside out. The first guide 161 has a cylindrical support shaft 168 that protrudes rightward from the right side of the upper end of the base 167, and a disk-shaped guide portion 169 that is provided to the right of the support shaft 168 and has a larger diameter than the support shaft 168. The second guide 162 has a cylindrical support shaft 168 that protrudes leftward from the left side of the upper end of the base 167, and a disk-shaped guide portion 169 that is provided to the left of the support shaft 168 and has a larger diameter than the support shaft 168. The third guide 163 has a cylindrical support shaft 168 that protrudes rightward from the right side of the lower end of the base 167, and a disk-shaped guide portion 169 that is provided to the right of the support shaft 168 and has a larger diameter than the support shaft 168. The fourth guide 164 has a cylindrical support shaft 168 that protrudes leftward from the left side of the lower end of the base 167, and a disk-shaped guide portion 169 that is located to the left of the support shaft 168 and has a larger diameter than the support shaft 168. The fifth guide 165 has a rectangular parallelepiped shape and is located at the right end of the upper end of the base 167 on the outdoor side, protruding toward the outdoors. The sixth guide 166 has a rectangular parallelepiped shape and is located at the left end of the upper end of the base 167 on the outdoor side, protruding toward the outdoors.

As shown in FIG. 8 , the structure 10 is provided with a positioning member 120. The positioning member 120 has an upper inclined portion 121 at its upper end and a lower inclined portion 122 at its lower end. The upper inclined portion 121 has a first inclined portion 123 that slopes downward toward the indoor side, and a second inclined portion 124 that slopes downward from the lower end of the first inclined portion 123 toward the outdoor side. The lower inclined portion 122 slopes downward toward the indoor side. The fifth guide 165 and the sixth guide 166 have lower end corners 165a, 166a, which are the corners of their lower ends on the outdoor side, that can abut against the first inclined portion 123 of the upper inclined portion 121 of the positioning member 120. The lower end corner 167a, which is the corner of the lower end of the base 167 on the outdoor side, can abut against the lower inclined portion 122 of the positioning member 120. Therefore, when the second water stop 160 is moved downward, the lower corners 165a, 166a of the fifth guide 165 and sixth guide 166 slide diagonally downward while abutting against the upper inclined portion 121 of the positioning member 120, and the lower corner 167a of the base 167 slides diagonally downward while abutting against the lower inclined portion 122 of the positioning member 120, thereby positioning the second water stop 160.

As explained above, in this embodiment, the base 167, first guide 161, second guide 162, third guide 163, fourth guide 164, fifth guide 165, and sixth guide 166 are all integrally joined. Therefore, the variation in the distance between the guides is reduced compared to when the first guide 161 to sixth guide 166 are each individually provided on the base 167.

[Fourth embodiment]
Next, a fourth embodiment will be described, in which the same components as those in the first to third embodiments are designated by the same reference numerals and will not be described again.

Figure 9 is a schematic and exemplary perspective view of the upper part of the third waterstop 260 according to the fourth embodiment. Figure 10 is an exemplary side view of the third waterstop 260 shown in Figure 9 as seen from the side.

As shown in Figures 9 and 10, the third water stop 260 according to the fourth embodiment has a rectangular groove 261 extending in the left-right direction. The indoor side of the third water stop 260 is provided with an upper protruding wall 262 that protrudes downward and extends in the left-right direction, and a lower protruding wall 263 that protrudes upward and extends in the left-right direction. The lower wall surface 262a of the upper protruding wall 262 and the upper wall surface 263a of the lower protruding wall 263 are positioned at a distance in the vertical direction. This provides an opening 264 between the lower wall surface 262a and the upper wall surface 263a.

Furthermore, rectangular groove 261 is composed of upper surface 265, lower surface 266, outer surface 267, and inner surface 268. Inner surface 268 is the outdoor-facing surface of upper protruding wall 262 and lower protruding wall 263. Outer surface 267 is located at a distance from inner surface 268 toward the outdoor side and faces inner surface 268. Upper surface 265 is located above lower wall surface 262a of upper protruding wall 262. Lower surface 266 is located below upper wall surface 263a of lower protruding wall 263. Upper surface 265 faces lower surface 266 at a distance in the vertical direction. The space surrounded by upper surface 265, lower surface 266, outer surface 267, and inner surface 268 forms rectangular groove 261. As shown in Figure 9, the plate nut 200 has a screw hole 201 in the center and a screw thread 202 on the inner periphery of the screw hole 201. As shown by the arrow in Figure 9, the plate nut 200 can be inserted into the rectangular groove 261.

As described above, in this embodiment, the plate nut 200 can be assembled to the third waterstop 260 without drilling holes in the third waterstop 260. For example, the handle 61 shown in FIG. 2 can be attached to the third waterstop 260 without drilling holes in the third waterstop 260. Specifically, for example, the upper leg 62 and lower leg 64 of the handle 61 shown in FIG. 2 are fastened to the plate nut 200, and then the plate nut 200 is inserted into the rectangular groove 261.

Fifth Embodiment
Next, a fifth embodiment will be described, with the same components as those in the first to fourth embodiments being designated by the same reference numerals and the description thereof being omitted.

Figure 11 is a perspective view of the lower part of the fourth waterstop 360 according to the fifth embodiment, viewed obliquely from below.

11 , the fourth waterstop 360 includes an inner wall 364 located on the indoor side and extending in the left-right direction; a side wall 363 extending from the left-right edge 364a of the inner wall 364 toward the outdoor side along the thickness direction (inside-outside direction) of the fourth waterstop 360; an outer wall 362 located on the outdoor side and extending in the left-right direction from the edge 363a of the side wall 363; and a bottom wall 365 located below the outer wall 362, side wall 363, and inner wall 364. In this embodiment, waterstop rubber strips 371 are provided on the left-right edges of the inner wall 364 and on the indoor-facing edge of the bottom wall 365. Specifically, waterstop rubber strips 371 are provided on the left-right edges of the inner wall 364 along the up-down direction. Waterstop rubber strips 371 are provided on the indoor-facing edge of the bottom wall 365 along the left-right direction. Here, water-absorbing tape 372 is attached to the surface of the water-stop rubber 371 in areas shown hatched for convenience. This water-absorbing tape 372 is coated with a highly absorbent polymer, which has excellent characteristics such as water absorption efficiency, water absorption speed, and water retention. Therefore, when the water-absorbing tape 372 becomes wet, it swells significantly, restricting the penetration of water. Note that, for example, 3M (registered trademark) Joint Water Stop Tape 2237 manufactured by 3M Company can be used as the water-absorbing tape 372.

As explained above, in this embodiment, strip-shaped water-stopping rubber 371 with water-absorbing tape 372 attached is attached to the left and right ends of the inner wall 364 and the indoor end of the bottom wall 365. Here, for example, at the corners where the side wall 363 and bottom wall 365 intersect, gaps are likely to form between the guide rail 20 and the floor 13 (see Figure 1). Furthermore, if the floor 13 has many irregularities, gaps are likely to form between the floor 13 and the water-stopping rubber 371. However, because the water-absorbing tape 372 is attached to the water-stopping rubber 371, when water seeps in from the outdoors, the water-absorbing tape 372 seeps in and swells significantly, sealing off the aforementioned gaps and restricting water intrusion.

The above describes exemplary embodiments of the present invention, but these are merely examples and are not intended to limit the scope of the invention. These embodiments can be implemented in a variety of other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. These embodiments are within the scope and spirit of the invention, as well as the invention and its equivalents as set forth in the claims. Furthermore, the configurations and shapes of each embodiment and each variant can be partially interchanged and implemented. Furthermore, the specifications of each configuration and shape (structure, type, direction, shape, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.

For example, in the first embodiment, the first recess 85 and second recess 185 are shown, which can hold the first engaging portion 76 of the first stopper pin 70. However, the recesses are not limited to these. For example, as shown in FIG. 12 , a stepped portion 370 (fourth recess 385, engaged portion) extending elongated in the left-right direction may be used as the recess. Specifically, the stepped portion 370 may be provided in the concrete floor 13, and the fourth support plate 380 may be fixed on top of this stepped portion 370. The fourth support plate 380 has an upper wall 381, a vertical wall 382 extending downward from the indoor-side edge 381a of the upper wall 381, and a bottom wall 383 extending indoors from the lower end 382a of the vertical wall 382. When the first engaging portion 76 of the first stopper pin 70 abuts against the vertical wall 382, the first waterstop 60 is held against the floor 13.
