図１，２に示されるように、防水装置１Ａは、建物等の構造物の壁１０（側壁）に設けられた開口部１１に対応して、設けられる。開口部１１は、床面１２の上側に隣接し、側方（Ｘ方向）に向けて開口している。開口部１１は、上下方向に長い長方形状（四角形状）に形成される。構造物の開口部１１の縁は、床面１２と、左右両側で上下方向に延びる方立１３，１３（柱）と、上方で左右方向（側方）に延びる梁（図示されず）とによって構成される。方立１３は、角柱状に構成される。なお、開口部１１の屋内側には、開口部１１を開閉可能に覆う扉１５，１５が設けられている。扉１５は、スライドドア（所謂自動ドア）である。扉１５は、壁１０および床面１２に沿って、図１の左右方向（Ｙ方向およびその反対方向）に、開位置（図示されず）と閉位置（図１）との間で移動する。なお、屋外側および屋内側とは、説明上わかりやすくするための便宜上の表現であって、水が浸入する可能性がある場合の上流側および下流側を意味する。本発明は、例えば廊下等の通路のような家屋や部屋等の概念が必ずしも明確にならない場所に設置された扉に対しても適用できる。 <First Embodiment>
As shown in FIGS. 1 and 2, the waterproof device 1 </ b> A is provided corresponding to the opening 11 provided in the wall 10 (side wall) of a structure such as a building. The opening 11 is adjacent to the upper side of the floor 12 and opens toward the side (X direction). The opening 11 is formed in a rectangular shape (square shape) that is long in the vertical direction. The edge of the opening 11 of the structure is formed by a floor 12, uprights 13 and 13 (columns) extending in the vertical direction on both the left and right sides, and a beam (not shown) extending in the horizontal direction (side) on the upper side. Composed. The stand 13 is configured in a prismatic shape. Note that doors 15 and 15 are provided on the indoor side of the opening 11 so as to cover the opening 11 in an openable and closable manner. The door 15 is a slide door (so-called automatic door). The door 15 moves along the wall 10 and the floor 12 between the open position (not shown) and the closed position (FIG. 1) in the left-right direction (Y direction and the opposite direction) in FIG. In addition, the outdoor side and the indoor side are expressions for convenience for easy understanding, and mean an upstream side and a downstream side when water may enter. The present invention can also be applied to doors installed in places where concepts such as houses and rooms such as passages such as corridors are not always clear.

防水装置１Ａは、遮水板２を有する。遮水板２は、長方形（四角形）の板状に構成される。遮水板２は、開口部１１の少なくとも下部を覆う。具体的に、遮水板２は、その厚さ方向が床面１２（Ｘ方向）と略平行な姿勢で、床面１２上に接して起立するとともに、方立１３に屋外側から接する。このように遮水板２が開口部１１の下部を覆った状態で、遮水板２の端部２ａ（下端部）と床面１２との間、および遮水板２の左右両側の端部２ｂ（側端部）と方立１３（の外面）との間がシールされることにより、開口部１１を介した屋内への雨水等の水の浸入が、抑制される。また、遮水板２は、ケース（例えば金属材料等）と、当該ケースの内部に収容された比較的軽量な材料（例えば発泡材料等）とを有し、全体として比較的軽量となるよう構成されている。遮水板２の全体の比重は、例えば、水の比重よりも小さく設定されうる。これにより、操作者は、遮水板２の運搬や、取り付け、取り外し等を、より容易に行える。なお、床面１２とは、説明上わかりやすくするための便宜上の表現であって、通常の床面のみならず、コンクリート面や地面等の開口部１１の下方に位置する面をも意味する。   The waterproof device 1 </ b> A has a water shielding plate 2. The water shielding plate 2 is configured in a rectangular (quadrangle) plate shape. The water shielding plate 2 covers at least the lower part of the opening 11. Specifically, the water shielding plate 2 stands in contact with the floor surface 12 in a posture in which the thickness direction is substantially parallel to the floor surface 12 (X direction), and contacts the vertical wall 13 from the outdoor side. Thus, in the state which covered the lower part of the opening part 11 with the water-shielding board 2, between the edge part 2a (lower end part) and the floor surface 12 of the water-shielding board 2, and the edge part of the right-and-left both sides of the water-shielding board 2 By sealing between 2b (side end part) and the upright 13 (outer surface thereof), infiltration of water such as rainwater into the room through the opening 11 is suppressed. Further, the water shielding plate 2 includes a case (for example, a metal material) and a relatively light material (for example, a foam material) accommodated inside the case, and is configured to be relatively light as a whole. Has been. The total specific gravity of the water shielding plate 2 can be set smaller than the specific gravity of water, for example. As a result, the operator can more easily carry, attach, and remove the water shielding plate 2. In addition, the floor surface 12 is an expression for convenience for the sake of easy understanding, and means not only a normal floor surface but also a surface located below the opening 11 such as a concrete surface or the ground.

図４に示されるように、端部２ａと床面１２との間、および端部２ｂと方立１３との間には、それぞれ、シール部材３が設けられている。シール部材３は、例えば、エラストマ等の弾性材料で構成される。シール部材３は、遮水板２と構造物（床面１２あるいは方立１３）との間に挟まれることで、弾性的に圧縮され、面圧を生じる。この面圧によって、水の浸入がより一層確実に抑制されうる。なお、本実施形態では、シール部材３は、遮水板２に設けられるが、シール部材３の少なくとも一部は、構造物側に設けられてもよい。また、水の浸入が抑制されるとは、水の浸入が阻止されたり防止されたりする意味をも含む。   As shown in FIG. 4, seal members 3 are provided between the end 2 a and the floor 12 and between the end 2 b and the upright 13, respectively. The seal member 3 is made of an elastic material such as an elastomer. The seal member 3 is elastically compressed by being sandwiched between the water-impervious plate 2 and the structure (the floor surface 12 or the vertical wall 13), thereby generating a surface pressure. By this surface pressure, the intrusion of water can be more reliably suppressed. In this embodiment, the seal member 3 is provided on the water shielding plate 2, but at least a part of the seal member 3 may be provided on the structure side. In addition, the suppression of water intrusion also includes the meaning that water intrusion is prevented or prevented.

また、左右の方立１３には、それぞれ、図２〜４に示される押付部材４Ａが設けられる。押付部材４Ａは、それぞれ、遮水板２の例えば端部２ｃ（上端部）を、床面１２（下方）に向けて押し付ける。遮水板２は、押付部材４Ａと床面１２との間に挟まれることで、開口部１１を屋外側から覆った位置に固定される。   Further, the left and right vertical stands 13 are each provided with a pressing member 4A shown in FIGS. Each of the pressing members 4A presses, for example, the end 2c (upper end) of the water shielding plate 2 toward the floor 12 (downward). The water shielding plate 2 is fixed between the pressing member 4A and the floor surface 12 so as to cover the opening 11 from the outdoor side.

図３，４に示されるように、押付部材４Ａは、方立１３に着脱可能に取り付けられるブラケットとして構成されている。押付部材４Ａは、例えば、板状の金属材料を折り曲げることで構成されうる。押付部材４Ａは、壁部４ａ（前壁部、基部）や、壁部４ｂ（側壁部、フランジ部）、壁部４ｃ（下壁部、フランジ部）、等の部分を有する。壁部４ａは、方立１３の屋外側の面１３ａ（前面）の屋外側に対向する。壁部４ａは、面１３ａと接触しうる。壁部４ａは、長方形状（四角形状）の板状に構成されている。また、二つの壁部４ｂが、壁部４ａの左右それぞれの端部から屋内側（Ｘ方向の反対方向）に向けて突出し、方立１３の左右両側のいずれかの面１３ｂと対向する。壁部４ｂは、長方形状（四角形状）の板状に構成されている。壁部４ａと二つの壁部４ｂとで構成される上方からの視線で略Ｕ字状の部分が、方立１３を屋外側から囲っている。壁部４ｂのうち一方（図３の例では左側の壁部４ｂ）は、左右両側のいずれかの面１３ｂから離間し、もう一方（図３の例では右側の壁部４ｂ）は、面１３ｂと接触しうる。面１３ｂから離間して設けられる壁部４ｂには、雌ねじ穴４ｄが設けられ、この雌ねじ穴４ｄに、固定部材５の雄ねじ部５ｂが通されている。また、壁部４ａの下方側の端部からは屋外側（Ｘ方向）に向けて壁部４ｃが突出している。壁部４ｃは、開口部１１を覆う位置にある遮水板２の端部２ｃ（面、端面）と対向する。壁部４ｃは、端部２ｃと離間している。壁部４ｃは、長方形状（四角形状）の板状に構成されている。壁部４ａと壁部４ｃとは、側面視でＬ字状に接続されている。   As shown in FIGS. 3 and 4, the pressing member 4 </ b> A is configured as a bracket that is detachably attached to the stand 13. The pressing member 4A can be configured, for example, by bending a plate-shaped metal material. 4 A of pressing members have parts, such as wall part 4a (front wall part, base part), wall part 4b (side wall part, flange part), and wall part 4c (lower wall part, flange part). The wall portion 4 a faces the outdoor side of the outdoor side surface 13 a (front surface) of the vertical wall 13. The wall 4a can contact the surface 13a. The wall 4a is configured in a rectangular (quadrangle) plate shape. Moreover, the two wall parts 4b protrude toward the indoor side (the direction opposite to the X direction) from the left and right ends of the wall part 4a, and face either one of the left and right surfaces 13b of the stand 13. The wall 4b is configured in a rectangular (quadrangle) plate shape. A substantially U-shaped portion that is composed of the wall portion 4a and the two wall portions 4b from above and surrounds the stand 13 from the outdoor side. One of the wall portions 4b (the left wall portion 4b in the example of FIG. 3) is separated from one of the left and right surfaces 13b, and the other (the right wall portion 4b in the example of FIG. 3) is the surface 13b. Can come into contact with A female screw hole 4d is provided in the wall part 4b provided apart from the surface 13b, and the male screw part 5b of the fixing member 5 is passed through the female screw hole 4d. Moreover, the wall part 4c protrudes toward the outdoor side (X direction) from the edge part of the downward side of the wall part 4a. The wall part 4c opposes the edge part 2c (surface, end surface) of the water shielding board 2 in the position which covers the opening part 11. FIG. The wall 4c is separated from the end 2c. The wall 4c is configured in a rectangular (quadrangle) plate shape. The wall 4a and the wall 4c are connected in an L shape in a side view.

押付部材４Ａは、固定部材５を有している。押付部材４Ａは、方立１３の面１３ｂから離間した壁部４ｂに取り付けられた固定部材５Ａ（５）によって方立１３に固定されるとともに、壁部４ｃに取り付けられた固定部材５Ｂ（５）を介して遮水板２を下方に押し付けている。固定部材５Ａおよび固定部材５Ｂは同一の構造を有している。固定部材５は、ヘッド部５ａ（ハンドル部）や、ねじ部５ｂ、座部５ｃ等の部分を有する。ねじ部５ｂ（雄ねじ部）は、壁部４ｂ，４ｃに設けられた雌ねじ穴４ｄに挿入される。ねじ部５ｂの一方側、すなわち面１３ｂまたは端部２ｃの反対側には、ヘッド部５ａが固定されている。また、ねじ部５ｂの他方側、すなわちヘッド部５ａとは反対側（端部側）には、座部５ｃが配置されている。なお、図３では、固定部材５Ｂの座部５ｃのみが示されているが、固定部材５Ａにも同様の座部が設けられている。操作者は、手指や工具等を用いてヘッド部５ａを回すことで、固定部材５をねじ込む。固定部材５Ａのねじ部５ｂの回転に伴って、固定部材５Ａが接触する面１３ｂと壁部４ｂとの間隔が広がり、固定部材５Ａの座部５ｃ（図示されず、またはねじ部５ｂの端部）と、他方側の壁部４ｂ（図３では右上側の壁部４ｂ）との間に、方立１３が挟まれた状態が得られる。このようにして、固定部材５Ａにより、押付部材４Ａが方立１３に取り付けられる。また、固定部材５Ｂのねじ部５ｂの回転に伴って、固定部材５Ｂが接触する端部２ｃと壁部４ｃとの間隔が広がる。すなわち、遮水板２の端部２ｃは、方立１３に取り付けられた押付部材４Ａから、固定部材５Ｂを介して下方（床面１２に向けて）押し付けられる。操作者は、固定部材５Ａを緩めることで、押付部材４Ａを方立１３から取り外すことができる。また、操作者は、固定部材５Ｂの締付トルクの調節（設定）によって、遮水板２を下方へ押す力の大きさ、ひいては、シール部材３の床面１２との間に介在する部分３ａに作用する面圧の大きさを、調節（設定）できる。また、操作者は、固定部材５Ｂを緩めることで、遮水板２を開口部１１を覆う位置から取り外す（移動させる）ことができる。なお、ねじ部５ｂ（雌ねじ穴４ｄ）は、セルフロック機能を有してもよい。   The pressing member 4 </ b> A has a fixing member 5. The pressing member 4A is fixed to the vertical 13 by a fixing member 5A (5) attached to the wall 4b spaced from the surface 13b of the vertical 13, and a fixing member 5B (5) attached to the wall 4c. The water shielding plate 2 is pressed downward via The fixing member 5A and the fixing member 5B have the same structure. The fixing member 5 includes a head portion 5a (handle portion), a screw portion 5b, a seat portion 5c, and the like. The screw portion 5b (male screw portion) is inserted into the female screw hole 4d provided in the wall portions 4b and 4c. The head portion 5a is fixed to one side of the screw portion 5b, that is, the opposite side of the surface 13b or the end portion 2c. Further, a seat portion 5c is disposed on the other side of the screw portion 5b, that is, on the opposite side (end portion side) from the head portion 5a. In FIG. 3, only the seat portion 5c of the fixing member 5B is shown, but the same seat portion is also provided in the fixing member 5A. The operator screws the fixing member 5 by turning the head portion 5a using fingers or tools. As the screw portion 5b of the fixing member 5A rotates, the space between the surface 13b and the wall portion 4b with which the fixing member 5A comes into contact increases, and the seat portion 5c (not shown or the end portion of the screw portion 5b) of the fixing member 5A increases. ) And the wall 4b on the other side (the wall 4b on the upper right side in FIG. 3). In this way, the pressing member 4A is attached to the vertical 13 by the fixing member 5A. Further, with the rotation of the screw portion 5b of the fixing member 5B, the interval between the end portion 2c and the wall portion 4c with which the fixing member 5B comes into contact increases. That is, the end 2c of the water shielding plate 2 is pressed downward (toward the floor 12) from the pressing member 4A attached to the vertical 13 via the fixing member 5B. The operator can remove the pressing member 4A from the stand 13 by loosening the fixing member 5A. In addition, the operator adjusts (sets) the tightening torque of the fixing member 5B to adjust the magnitude of the force pushing the water shielding plate 2 downward, and thus the portion 3a interposed between the sealing member 3 and the floor surface 12. It is possible to adjust (set) the size of the surface pressure acting on the surface. Further, the operator can remove (move) the water shielding plate 2 from the position covering the opening 11 by loosening the fixing member 5B. Note that the screw portion 5b (female screw hole 4d) may have a self-locking function.

図４に示されるように、遮水板２は、押付部材４Ａ（固定部材５Ｂ）と床面１２との間に上下方向（Ｚ方向）に挟まれるとともに、押付部材４Ａ（固定部材５Ｂ）と方立１３との間に開口部１１の開口方向（Ｘ方向）に挟まれる。したがって、図４に示されるように、遮水板２の端部２ａと床面１２との間には、シール部材３の弾性変形に伴う力Ｆｐ１（弾性力）が生じてシール部材３の面圧が高まり、遮水板２の端部２ｂと方立１３との間には、シール部材３の弾性変形に伴う力Ｆｐ２（弾性力）が生じてシール部材３の面圧が高まる。これにより、端部２ａと床面１２との間、および端部２ｂと方立１３との間の面圧が増大し、これらの位置でのシール性が向上する。また、面圧の増大によって高まったシール部材３の下方の部分３ａと床面１２との摩擦力により、遮水板２（の端部２ａ）の開口部１１から離れる方向（Ｘ方向）への移動が抑制される。   As shown in FIG. 4, the water shielding plate 2 is sandwiched in the vertical direction (Z direction) between the pressing member 4A (fixing member 5B) and the floor surface 12, and the pressing member 4A (fixing member 5B). It is sandwiched between the uprights 13 in the opening direction (X direction) of the opening 11. Therefore, as shown in FIG. 4, a force Fp <b> 1 (elastic force) accompanying elastic deformation of the seal member 3 is generated between the end 2 a of the water shielding plate 2 and the floor surface 12, and the surface of the seal member 3. The pressure increases, and a force Fp2 (elastic force) associated with the elastic deformation of the seal member 3 is generated between the end 2b of the water shielding plate 2 and the upright 13, and the surface pressure of the seal member 3 is increased. Thereby, the surface pressure between the edge part 2a and the floor surface 12 and between the edge part 2b and the upright 13 increases, and the sealing performance in these positions is improved. Further, due to the frictional force between the lower portion 3a of the seal member 3 and the floor surface 12, which has been increased by increasing the surface pressure, the direction away from the opening 11 of the water shielding plate 2 (the end portion 2a) in the direction (X direction). Movement is suppressed.

このように、本実施形態では、例えば、遮水板２が床面１２と接するとともに開口部１１を屋外側から覆った状態で、方立１３（構造物、開口部１１の縁部）に固定されて遮水板２を少なくとも床面１２に向けて押し付ける押付部材４Ａを備える。よって、例えば、比較的簡素な構成によって、遮水板２を開口部１１を覆う位置に留めることができる。また、例えば、押付部材４Ａにより遮水板２を床面１２側または方立１３側に押し付けてシール部材３を弾性変形させ、遮水板２と床面１２との間、または遮水板２と方立１３との間のシール性を向上できる。また、例えば、遮水板２が比較的軽量である場合（例えば、遮水板２の全体の比重が水の比重より小さい場合等）に、押付部材４Ａの押力がシール性の向上に資する場合がある。   Thus, in this embodiment, for example, the water shielding plate 2 is in contact with the floor 12 and fixed to the stand 13 (the structure, the edge of the opening 11) with the opening 11 covered from the outdoor side. And a pressing member 4 </ b> A for pressing the water shielding plate 2 toward at least the floor surface 12. Therefore, for example, the water shielding plate 2 can be held at a position covering the opening 11 with a relatively simple configuration. Further, for example, the sealing member 3 is elastically deformed by pressing the water shielding plate 2 against the floor surface 12 or the side wall 13 by the pressing member 4A, and between the water shielding plate 2 and the floor surface 12 or the water shielding plate 2. And the seal 13 can be improved. Further, for example, when the water shielding plate 2 is relatively light (for example, when the specific gravity of the entire water shielding plate 2 is smaller than the specific gravity of water), the pressing force of the pressing member 4A contributes to the improvement of the sealing performance. There is a case.

また、本実施形態では、例えば、押付部材４Ａは、方立１３（開口部１１の縁部）に固定される。よって、例えば、押付部材４Ａを、方立１３を利用した比較的簡素な構成として得ることができる。   In the present embodiment, for example, the pressing member 4A is fixed to the vertical 13 (the edge of the opening 11). Therefore, for example, the pressing member 4 </ b> A can be obtained as a relatively simple configuration using the stand 13.

また、本実施形態では、例えば、遮水板２に設けられて床面１２と接する弾性変形可能なシール部材３（の部分３ａ）を備える。よって、例えば、シール部材３の弾性力によってシール性を高めるとともに当該弾性力によって生じる摩擦力により遮水板２が開口部１１を覆う位置から外れ難くなる。   Further, in the present embodiment, for example, an elastically deformable seal member 3 (part 3a) provided on the water shielding plate 2 and in contact with the floor surface 12 is provided. Therefore, for example, the sealing performance is enhanced by the elastic force of the seal member 3 and the water shielding plate 2 is hardly detached from the position covering the opening 11 by the frictional force generated by the elastic force.

＜第２実施形態＞
図５，６に示される本実施形態の防水装置１Ｂでは、押付部材４Ｂの構成が、上記第１実施形態とは異なっている。押付部材４Ｂは、開口部１１の上方で側方に延びる部材１６（例えば、天井や梁等の構造物）の面１６ａと遮水板２の端部２ｃ（上端部、端面）との間に上下に突っ張っている。押付部材４Ｂは、長手方向に座屈することなく相互にスライド可能な少なくとも二つの（複数の）上下方向に延びた部材４１，４２を有する。押付部材４Ｂの長手方向の両端部には、滑り止め部材４ｅ，４ｆが設けられている。滑り止め部材４ｅ，４ｆは、例えば、エラストマや合成樹脂材料等で構成されたキャップである。部材４１，４２は、長手方向の中間部分で少なくとも部分的に重なり合うとともに、いずれも少なくともいずれか一方が部分的に筒状に構成されており、当該筒状部内に、ねじ機構や弾性機構（コイルスプリング等）を含む突張機構（図示されず）が設けられている。突張機構は、例えば、操作者が部材４１，４２を長手方向の軸回りに相対的に回転させることで突張力の大きさを調節できるよう構成されている。このような構成において、操作者が突張機構を調節して押付部材４Ｂに長手方向（上下方向）の突張力を生じさせることで、遮水板２は、押付部材４Ｂと床面１２との間に上下方向（Ｚ方向）に挟まれるとともに、押付部材４Ｂと方立１３との間に開口部１１の開口方向（Ｘ方向）に挟まれる。よって、本実施形態によっても、押付部材４Ｂによって、端部２ａと床面１２との間、および端部２ｂと方立１３との間の面圧が増大し、これらの位置でのシール性が向上する。また、面圧の増大によって高まったシール部材３の下方の部分３ａと床面１２との摩擦力により、遮水板２（の端部２ａ）の開口部１１から離れる方向（Ｘ方向）への移動が抑制される。本実施形態の押付部材４Ｂによっても、上記第１実施形態と同様の作用および結果（効果）が得られる。 Second Embodiment
In the waterproof device 1B of the present embodiment shown in FIGS. 5 and 6, the configuration of the pressing member 4B is different from that of the first embodiment. The pressing member 4B is provided between a surface 16a of a member 16 (for example, a structure such as a ceiling or a beam) that extends laterally above the opening 11 and an end 2c (upper end, end surface) of the water shielding plate 2. It stretches up and down. The pressing member 4B includes at least two (a plurality of) vertically extending members 41 and 42 that can slide relative to each other without buckling in the longitudinal direction. Anti-slip members 4e and 4f are provided at both ends in the longitudinal direction of the pressing member 4B. The anti-slip members 4e and 4f are caps made of, for example, an elastomer or a synthetic resin material. The members 41 and 42 are at least partially overlapped at an intermediate portion in the longitudinal direction, and at least one of the members 41 and 42 is partially configured in a cylindrical shape, and a screw mechanism or an elastic mechanism (coil) is included in the cylindrical portion. A tension mechanism (not shown) including a spring or the like is provided. For example, the tension mechanism is configured such that the operator can adjust the magnitude of the tension by rotating the members 41 and 42 relatively around the longitudinal axis. In such a configuration, the water shielding plate 2 is formed between the pressing member 4 </ b> B and the floor surface 12 by adjusting the tensioning mechanism and causing the pressing member 4 </ b> B to generate a longitudinal tension (vertical direction). It is sandwiched between the pressing member 4 </ b> B and the stand 13 in the opening direction (X direction) of the opening 11. Therefore, also in this embodiment, the pressing member 4B increases the surface pressure between the end portion 2a and the floor surface 12, and between the end portion 2b and the upright 13, and the sealing performance at these positions is increased. improves. Further, due to the frictional force between the lower portion 3a of the seal member 3 and the floor surface 12, which has been increased by increasing the surface pressure, the direction away from the opening 11 of the water shielding plate 2 (the end portion 2a) in the direction (X direction). Movement is suppressed. Also by the pressing member 4B of this embodiment, the same operation and result (effect) as those of the first embodiment can be obtained.

＜第３実施形態＞
図７，８に示される本実施形態の防水装置１Ｃでは、押付部材４Ｃの構成が、上記第１、第２実施形態とは異なっている。押付部材４Ｃは、くさび部材として構成されている。方立１３の屋外側の面１３ａには、遮水板２の端部２ｃ（上端部、端面）上に開口するように、開口部１３ｃ（凹部）が設けられている。押付部材４Ｃは、基部４ｈと、先細り形状（くさび状）に構成された尖部４ｇとを有する。尖部４ｇには、適宜段差や凹凸形状が設けられうる。この段差や凹凸形状として、押付部材４Ｃの屋内側への移動に伴って遮水板２を屋内側へ押し付ける（引き摺る）ための突起（突条）や、凹部、溝等（引掛部）が設けられてもよい。操作者は、基部４ｈを押すことで押付部材４Ｃを端部２ｃ上で屋内側（Ｘ方向の反対方向）にスライドさせながら開口部１３ｃ内に押し込む。図８に示されるように尖部４ｇが開口部１３ｃ内に押し込まれると、尖部４ｇを介して遮水板２が床面１２に向けて下方に押される。このような構成において、遮水板２は、押付部材４Ｃと床面１２との間に上下方向（Ｚ方向）に挟まれるとともに、押付部材４Ｃと方立１３との間に開口部１１の開口方向（Ｘ方向）に挟まれる。よって、本実施形態によっても、押付部材４Ｃによって、端部２ａと床面１２との間、および端部２ｂと方立１３との間の面圧が増大し、これらの位置でのシール性が向上する。また、面圧の増大によって高まったシール部材３の下方の部分３ａと床面１２との摩擦力により、遮水板２（の端部２ａ）の開口部１１から離れる方向（Ｘ方向）への移動が抑制される。本実施形態の押付部材４Ｃによっても、上記第１、第２実施形態と同様の作用および結果（効果）が得られる。 <Third Embodiment>
In the waterproof device 1C of the present embodiment shown in FIGS. 7 and 8, the configuration of the pressing member 4C is different from those of the first and second embodiments. The pressing member 4C is configured as a wedge member. An opening 13c (concave portion) is provided on the outdoor surface 13a of the vertical wall 13 so as to open on the end 2c (upper end, end surface) of the water shielding plate 2. The pressing member 4C includes a base portion 4h and a pointed portion 4g configured in a tapered shape (wedge shape). The apex 4g may be provided with a step or uneven shape as appropriate. As this step or uneven shape, there are provided protrusions (protrusions), concave portions, grooves, etc. (hooking portions) for pressing (sliding) the water shielding plate 2 toward the indoor side as the pressing member 4C moves to the indoor side. May be. The operator pushes the pressing member 4C into the opening 13c while sliding the pressing member 4C indoors (opposite to the X direction) on the end 2c by pressing the base 4h. As shown in FIG. 8, when the cusp 4g is pushed into the opening 13c, the water shielding plate 2 is pushed downward toward the floor 12 through the cusp 4g. In such a configuration, the water shielding plate 2 is sandwiched between the pressing member 4 </ b> C and the floor surface 12 in the vertical direction (Z direction), and the opening 11 is opened between the pressing member 4 </ b> C and the stand 13. It is sandwiched in the direction (X direction). Therefore, also in this embodiment, the pressing member 4C increases the surface pressure between the end portion 2a and the floor surface 12 and between the end portion 2b and the upright 13, and the sealing performance at these positions is increased. improves. Further, due to the frictional force between the lower portion 3a of the seal member 3 and the floor surface 12, which has been increased by increasing the surface pressure, the direction away from the opening 11 of the water shielding plate 2 (the end portion 2a) in the direction (X direction). Movement is suppressed. Also by the pressing member 4C of the present embodiment, the same operation and result (effect) as those of the first and second embodiments can be obtained.

＜第３実施形態の第１変形例＞
図９に示される本変形例の防水装置１Ｄも、上記第３実施形態と同様、くさび部材として構成された押付部材４Ｃを備えている。ただし、本変形例では、押付部材４Ｃが、遮水板２の端部２ｃ（上部）に、少なくとも固定位置Ｐ１（進入位置）と、非固定位置Ｐ２（待避位置）との間でスライド可能に支持されている（取り付けられている）。本変形例でも、第３実施形態と同様の作用および結果（効果）が得られる。また、変形例によれば、押付部材４Ｃが遮水板２に支持されている（取り付けられている）ため、非使用時に遮水板２とともに押付部材４Ｃをより容易に保管できる。 <First Modification of Third Embodiment>
The waterproof device 1D of the present modification shown in FIG. 9 also includes a pressing member 4C configured as a wedge member, as in the third embodiment. However, in this modification, the pressing member 4C is slidable at least between the fixed position P1 (entry position) and the non-fixed position P2 (retreat position) on the end 2c (upper part) of the water shielding plate 2. Supported (attached). Also in this modification, the same operation and result (effect) as in the third embodiment can be obtained. Moreover, according to the modification, since the pressing member 4C is supported (attached) to the water shielding plate 2, the pressing member 4C can be stored more easily together with the water shielding plate 2 when not in use.

＜第３実施形態の第２変形例＞
図１０に示される本変形例の防水装置１Ｅも、上記第３実施形態および第１変形例と同様、くさび部材として構成された押付部材４Ｃを備えている。そして、本変形例でも、第１変形例と同様、押付部材４Ｃが遮水板２にスライド可能に支持されている（取り付けられている）。ただし、本変形例では、方立１３のそれぞれの屋外側に隣接して、レール１７が設けられ、遮水板２はこのレール１７に支持されている。レール１７は、遮水板２の支持部の一例である。また、レール１７は、構造物の一例であり、開口部１１の縁部の一例でもある。 <Second Modification of Third Embodiment>
The waterproof device 1E of the present modification shown in FIG. 10 also includes a pressing member 4C configured as a wedge member, as in the third embodiment and the first modification. And also in this modification, 4 C of pressing members are supported by the water shielding board 2 so that sliding is possible (attached) similarly to the 1st modification. However, in this modification, a rail 17 is provided adjacent to each outdoor side of the stand 13, and the water shielding plate 2 is supported by the rail 17. The rail 17 is an example of a support portion for the water shielding plate 2. The rail 17 is an example of a structure and an example of an edge portion of the opening 11.

具体的に、レール１７は、上下方向（Ｚ方向）に延びており、屋外側に位置された帯状かつ板状の壁部１７ａと、屋内側に位置された帯状かつ板状の壁部１７ｃと、壁部１７ａと壁部１７ｃとを開口部１１から離れた側で繋ぐ帯状かつ板状の壁部１７ｂ（側壁部）と、を有している。これら壁部１７ａ，１７ｂ，１７ｃにより、Ｕ字状の断面形状を有した溝１７ｄ（凹部）が形成されている。図１０の右側のレール１７では、溝１７ｄは左側に開口し、図１０の左側のレール１７では、溝１７ｄは右側に開口している。このように互いに対向して開口する二つの溝１７ｄに、遮水板２の端部２ｂのそれぞれが収容される。すなわち、遮水板２の端部２ｂのそれぞれは、対応する溝１７ｄに囲われている。遮水板２の二つの端部２ｂは、二つの溝１７ｄ内に上方から挿入され、溝１７ｄ内を移動（スライド）する。操作者により、遮水板２は、下方に向けて動かされ、端部２ａが床面１２と接触して遮水板２が開口部１１の下部を覆う位置へ移動する。   Specifically, the rail 17 extends in the vertical direction (Z direction), and has a strip-like and plate-like wall portion 17a located on the outdoor side, and a strip-like and plate-like wall portion 17c located on the indoor side. And a strip-like and plate-like wall portion 17b (side wall portion) that connects the wall portion 17a and the wall portion 17c on the side away from the opening portion 11. These walls 17a, 17b, and 17c form a groove 17d (concave portion) having a U-shaped cross-sectional shape. In the right rail 17 in FIG. 10, the groove 17d opens to the left, and in the left rail 17 in FIG. 10, the groove 17d opens to the right. Thus, each of the edge part 2b of the water shielding board 2 is accommodated in the two groove | channels 17d opened facing each other. That is, each of the end portions 2b of the water shielding plate 2 is surrounded by the corresponding groove 17d. The two end portions 2b of the water shielding plate 2 are inserted into the two grooves 17d from above and move (slide) in the grooves 17d. By the operator, the water shielding plate 2 is moved downward, the end 2 a comes into contact with the floor surface 12, and the water shielding plate 2 moves to a position covering the lower portion of the opening 11.

遮水板２の屋外側の面２ｄ（外面）には、左右方向（Ｙ方向）に延びたレール２ｅが設けられている。押付部材４Ｃは、このレール２ｅにスライド可能（移動可能、往復可能）に支持されている。レール２ｅは、遮水板２の上下方向の略中央部に設けられている。ここで、溝１７ｄのＸ方向の幅は、遮水板２の厚さよりも大きく設定されている。したがって、操作者は、押付部材４Ｃを、レール２ｅに沿ってスライドさせ、遮水板２の面２ｄとレール１７の壁部１７ａとの隙間（屋外側の隙間）に差し込むことができる。押付部材４Ｃが隙間に差し込まれることにより、遮水板２は、当該押付部材４Ｃによってレール１７の屋内側の壁部１７ｃに押し付けられる。本変形例でも、図４と同様、遮水板２の端部２ｂの屋内側、および遮水板２の端部２ａの下側には、それぞれシール部材３が設けられている。よって、押付部材４Ｃによって壁部１７ｃ側に押し付けられたシール部材３により、壁部１７ｃとの間がシールされる。また、押付部材４Ｃにより、遮水板２は、床面１２側に押し付けられた状態で、レール１７に固定されうる。よって、遮水板２の端部２ａに設けられたシール部材３（図４）により、床面１２との間がシールされる。なお、本変形例では、遮水板２は、比較的重量が大きいものであってもよい。この場合、遮水板２の重量により、床面１２と面するシール部材３の面圧が高まりやすい。以上の本変形例によれば、上記第１変形例と同様の作用および結果（効果）が得られる。また、本変形例では、レール１７が設けられた分、遮水板２がより一層外れ難い。   A rail 2e extending in the left-right direction (Y direction) is provided on the outdoor surface 2d (outer surface) of the water shielding plate 2. The pressing member 4C is supported by the rail 2e so as to be slidable (movable and reciprocable). The rail 2e is provided at a substantially central portion of the water shielding plate 2 in the vertical direction. Here, the width of the groove 17 d in the X direction is set to be larger than the thickness of the water shielding plate 2. Therefore, the operator can slide the pressing member 4 </ b> C along the rail 2 e and insert it into the gap between the surface 2 d of the water shielding plate 2 and the wall portion 17 a of the rail 17 (outdoor side gap). When the pressing member 4C is inserted into the gap, the water shielding plate 2 is pressed against the wall portion 17c on the indoor side of the rail 17 by the pressing member 4C. Also in this modified example, as in FIG. 4, seal members 3 are provided on the indoor side of the end portion 2 b of the water shielding plate 2 and on the lower side of the end portion 2 a of the water shielding plate 2, respectively. Therefore, the space between the wall portion 17c and the seal member 3 pressed against the wall portion 17c by the pressing member 4C is sealed. Further, the water shielding plate 2 can be fixed to the rail 17 in a state of being pressed against the floor surface 12 by the pressing member 4C. Therefore, the space between the floor 12 is sealed by the seal member 3 (FIG. 4) provided at the end 2 a of the water shielding plate 2. In this modification, the water shielding plate 2 may be relatively heavy. In this case, the surface pressure of the sealing member 3 facing the floor surface 12 tends to increase due to the weight of the water shielding plate 2. According to the above modification, the same operation and result (effect) as those of the first modification can be obtained. Further, in the present modification, the water shielding plate 2 is more difficult to come off due to the provision of the rails 17.
