The water can be stopped. In addition, since it can be folded, it can be easily stored when not in use.

本発明の止水方法は、前記折り畳み式止水装置の左右の端部と前記一組の壁または柱の間及び前記折り畳み式止水装置の底部と前記床の間にシール材が設けられ、前記シール材が、独立発泡材で構成されることを特徴とする。   In the water stop method of the present invention, a sealing material is provided between left and right end portions of the foldable water stop device and the set of walls or pillars, and between a bottom portion of the foldable water stop device and the floor, and the seal The material is characterized by comprising a closed foam material.

一組の壁または柱の間及び前記折り畳み式止水装置の底部と前記床の間にシール材が設けられ、前記シール材が、独立発泡材で構成されるので、効果的に止水することができる。   Since a sealing material is provided between a pair of walls or pillars and between the bottom of the foldable water stop device and the floor, and the sealing material is made of an independent foam material, water can be effectively stopped. .

本発明の折り畳み式止水装置は、床の上に鉛直方向へ立設された一組の壁または柱の間の開口部を止水する折り畳み式止水装置であって、複数の止水板が折りたたみ可能に結合され、該折り畳み式止水装置の左右の端部及び該折り畳み式止水装置の底部に固着されたシール材と、前記折り畳み式止水装置を設置した際に該止水装置の全体形態を維持するとともに複数の前記止水板の左右の端部を前記一組の壁または柱に向けて押し付けるように働く加圧機構と、を備えることを特徴とする。   A foldable water stop device according to the present invention is a foldable water stop device for water stopping an opening between a pair of walls or pillars erected vertically on a floor, and a plurality of water stop plates Are connected to each other in a foldable manner, seal members fixed to the left and right ends of the foldable waterstop device and the bottom of the foldable waterstop device, and the waterstop device when the foldable waterstop device is installed. And a pressurizing mechanism that works to press right and left ends of the water blocking plates toward the set of walls or pillars.

複数の止水板が折りたたみ可能に結合されているので、展開しての設置と非使用時の貯蔵が容易になる。また、折り畳み式止水装置の左右の端部及び該折り畳み式止水装置の底部に固着されたシール材により効果的に止水することができる。そして、前記折り畳み式止水装置を設置した際に止水装置の全体形態を保ちつつ複数の前記止水板の左右の端部が前記一組の壁または柱に向けて押し付けられるように働く加圧機構を備えるので、折り畳み式止水装置の左右の端部が壁又は柱へ押し付けられて止水装置の全体形態の保持と止水が効果的に行われる。   Since the plurality of water stop plates are foldably coupled, it can be easily installed and stored when not in use. Moreover, it can stop water effectively by the sealing material adhering to the right and left ends of the foldable waterstop and the bottom of the foldable waterstop. Then, when the foldable water stop device is installed, the left and right end portions of the plurality of water stop plates work so as to be pressed against the set of walls or columns while maintaining the overall form of the water stop device. Since the pressure mechanism is provided, the left and right end portions of the foldable water stop device are pressed against the wall or the pillar, so that the overall form of the water stop device and water stop are effectively performed.

本発明の折り畳み式止水装置は、前記加圧機構が前記折り畳み式止水装置を前記一組の壁又は柱へ押し付ける加圧部材と該加圧部材による加圧に抗して前記折り畳み式止水装置の全体形態を維持する形態維持部材を備えることを特徴とする。   In the foldable water stop device of the present invention, the pressurizing mechanism presses the foldable water stop device against the set of walls or columns, and the foldable water stop device against pressure by the pressure member. It is provided with the form maintenance member which maintains the whole form of a water apparatus.

加圧機構が畳み式止水装置を一組の壁又は柱へ押し付ける加圧部材と該加圧部材による加圧に抗して前記折り畳み式止水装置の全体形態を維持する形態維持部材を備えるので、折り畳み式止水装置の全体形態が維持され止水装置が一体となって一組の壁または柱により支えられて効果的に止水することができる。   The pressurizing mechanism includes a pressurizing member that presses the foldable waterstop device against a set of walls or pillars, and a form maintaining member that maintains the overall form of the foldable waterstop device against pressure by the pressurizing member. Therefore, the whole form of a foldable water stop device is maintained, and the water stop device can be integrated and supported by a set of walls or pillars to effectively stop water.

本発明の折り畳み式止水装置は、形態維持部材が、向かい合う前記止水板が互いになす角度を所定の角度以上に保つ角度保持部材であることを特徴とする。   In the foldable water stop device of the present invention, the form maintaining member is an angle holding member that maintains an angle between the water stop plates facing each other at a predetermined angle or more.

複数の前記止水板が互いになす角度を所定の角度以上に保つ角度保持部材を備えるので止水板のなす角度が保持されて加圧部材による押圧により確実に止水装置にある止水板の左右の端部が前記一組の壁または柱に向けて押し付けられることができる。   Since the angle holding member that keeps the angle formed by the plurality of water stop plates at a predetermined angle or more is provided, the angle formed by the water stop plate is maintained, and the water stop plate in the water stop device is surely pressed by the pressure member. Left and right ends can be pressed against the set of walls or pillars.

本発明の折り畳み式止水装置は、前記形態維持部材が、前記止水板の左右の端部が当たる前記一組の壁又は柱に固定された係止部材であることを特徴とする。   The foldable water stop device of the present invention is characterized in that the form maintaining member is a locking member fixed to the set of walls or pillars against which the left and right ends of the water stop plate abut.

例えば2枚の止水板で構成される 本発明の折り畳み式止水装置は、その左右の両端を壁または柱に固定された係止部材で抑えられて止水装置の形態が維持される。係止部材は具体的には断面がL字やU字の部材が好適である。   For example, the foldable water stop device of the present invention constituted by two water stop plates is restrained at both left and right ends by a locking member fixed to a wall or a column, and the form of the water stop device is maintained. Specifically, the locking member is preferably a member having a L-shaped or U-shaped cross section.

本発明の折り畳み式止水装置は、前記加圧部材が、複数の前記止水板の凸になっている結合部に当たって締め付ける前記一組の壁または柱に係止されたロープであることを特徴とする。   In the foldable water stop device of the present invention, the pressurizing member is a rope locked to the pair of walls or pillars that are tightened by hitting the joints that are convex of the plurality of water stop plates. And

複数の前記止水板の凸になっている結合部に当たって締め付ける一組の壁または柱に係止されたロープは前記止水板の凸になっている結合部に当たることで止水装置を水平に広げる応力を生じることができる。   A rope locked to a pair of walls or pillars that are tightened by hitting the convex joints of the plurality of water stop plates hits the convex joints of the water stop plates so that the water stop device is leveled. A spreading stress can be generated.

ロープで加圧される折り畳み式止水装置の移動を防止する移動防止部材が、前記ロープとの間に上記止水板を挟む位置に設けられることを特徴とする。   A movement preventing member for preventing movement of the foldable water stop device pressurized by a rope is provided at a position sandwiching the water stop plate between the rope.

移動防止部材が、前記ロープとの間に上記止水板を挟む位置に設けられるので、ロープに加圧される折り畳み式止水装置の移動を防止して加圧を効果的に行うことができる。   Since the movement preventing member is provided at a position where the water stop plate is sandwiched between the rope and the rope, the movement of the foldable water stop device pressed against the rope can be prevented and pressure can be effectively applied. .

本発明の折り畳み式止水装置は、前記加圧部材が、複数の前記止水板の互いになす角度を広げるように前記止水板を押し広げる板間拡大部材であることを特徴とする。   In the foldable water stop device of the present invention, the pressurizing member is an inter-plate expansion member that pushes the water stop plate so as to widen an angle formed by the plurality of water stop plates.

前記加圧部材が、複数の前記止水板の互いになす角度を広げるように前記止水板を押し広げる板間拡大部材であるので、屏風を水平に広げる応力を生じることができる。   Since the pressurizing member is an inter-plate enlargement member that pushes the water stop plate so as to widen the angle formed by the plurality of water stop plates, a stress that spreads the folding screen horizontally can be generated.

本発明の折り畳み式止水装置は前記加圧部材が、前記止水装置の両端の止水板と該止水板に当たる前記一組の壁又は柱の一つとの間に張られたベルトであることを特徴とする。   In the foldable water stop device of the present invention, the pressurizing member is a belt stretched between water stop plates at both ends of the water stop device and one of the pair of walls or pillars that hit the water stop plate. It is characterized by that.

止水装置の両端の止水板を壁又は柱へ強く引きつけることで止水板に固着されたシール材がこれに当たる壁又は柱の間で強い圧力を受けて効果的に止水を行う。   By strongly attracting the water stop plates at both ends of the water stop device to the wall or column, the sealing material fixed to the water stop plate is subjected to strong pressure between the walls or columns hitting the water stop plate and effectively stops water.

本発明の折り畳み式止水装置は、複数の前記止水板の結合部の少なくとも片面が止水シートで覆われていることを特徴とする。   The foldable water stop device of the present invention is characterized in that at least one surface of a joint portion of the plurality of water stop plates is covered with a water stop sheet.

複数の前記止水板の結合部の少なくとも片面が止水シートで覆われているので効果的に止水板の結合部を止水することができる。   Since at least one surface of the joint portions of the plurality of water stop plates is covered with the water stop sheet, the joint portions of the water stop plates can be effectively stopped.

本発明の折り畳み式止水装置は、シール材が独立発泡材で構成されることを特徴とする。   The foldable water stop device of the present invention is characterized in that the sealing material is made of an independent foam material.

シール材が、独立発泡材で構成されるので水はシール材の中を通ることができないことから高い止水効果を得ることができる。   Since the sealing material is composed of an independent foam material, water cannot pass through the sealing material, so that a high water stop effect can be obtained.

以下、本発明の実施形態を図面に基づいて説明する。図1に示す本実施形態の折り畳み式止水装置は、建物へ向かう水を止水して建物内部の浸水を防止するために、床や地面16に立設される壁や柱11,12の間の開口部を止水するように水平方向へ展開されて設置される。以下、図1〜図4を用い屏風のように展開する折り畳み式止水装置の説明をする。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The foldable water stop device of the present embodiment shown in FIG. 1 is provided between walls and columns 11 and 12 erected on the floor or the ground 16 in order to stop water flowing toward the building and prevent inundation inside the building. It is developed and installed in the horizontal direction so as to stop the opening. Hereinafter, a foldable water stop device that develops like a folding screen will be described with reference to FIGS.

本実施形態において、折り畳み式止水装置の左右方向を幅方向とし、鉛直方向を上下方向とし、幅方向及び上下方向に略直交する方向を奥行方向とする。また、図1の折り畳み式止水装置の手前を前面、後ろを背面とする。   In this embodiment, let the left-right direction of a foldable water stop apparatus be a width direction, let a perpendicular direction be an up-down direction, and let the direction substantially orthogonal to a width direction and an up-down direction be a depth direction. Further, the front side of the foldable water stop device of FIG.

図1に示す折り畳み式止水装置は、主要構成部材の止水用の止水板1,2,3,4を有し、止水板1,2は結合部5、止水板2,3は結合部7、止水板3,4は結合部6で結合される。結合部は蝶番などで繋がれ、止水板は例えばベニヤ合板などの安価なものでよい。結合部は少なくとも片面に止水用のシートを貼ることで、水が漏れないようにする。シート材は例えばポリエステル加工された塩化ビニールシートなどの合成樹脂材料を用いることが好適である。   The foldable water stop device shown in FIG. 1 has water stop plates 1, 2, 3, and 4 for water stop as main components, and the water stop plates 1 and 2 are connected portions 5, water stop plates 2 and 3, respectively. Are coupled by the coupling part 7 and the water blocking plates 3 and 4 by the coupling part 6. The coupling portions are connected by a hinge or the like, and the water stop plate may be an inexpensive one such as a veneer plywood. The coupling part is made to prevent water from leaking by sticking a water stop sheet on at least one side. For the sheet material, it is preferable to use a synthetic resin material such as a vinyl chloride sheet processed with polyester.

また、止水板は防水用の塗装をすることで耐久性が増すことができる。止水シートは結合部だけでなく止水板全体を覆うように構成してもよい。止水板が結合部で接続されているので隣り合う止水板のなす角度は自由であり、止水板を折りたたむことで収納スぺースを節約することができる。   Moreover, durability can be increased by applying a waterproof coating to the water stop plate. You may comprise a water stop sheet | seat so that not only a connection part but the whole water stop board may be covered. Since the water stop plates are connected at the connecting portion, the angle formed by the adjacent water stop plates is free, and the storage space can be saved by folding the water stop plates.

使用する際に水平方向へ展開される折り畳み式止水装置は、その両端部を開口部を形成する柱や壁に当たるように設置される。折り畳み式止水装置の水平方向の両端部及び底部にはシール材が固着される。シール材はシール材が接する壁または柱や床へ押し付けられて水密な状態を作る。またシール材としては独立発泡材が好適である。   When used, the foldable water stop device that is deployed in the horizontal direction is installed so that both ends of the water stop device come into contact with pillars or walls that form openings. Sealing materials are fixed to both ends and the bottom in the horizontal direction of the folding water stop device. The sealing material is pressed against the wall or pillar or floor with which the sealing material is in contact, creating a watertight state. In addition, a closed foam material is suitable as the sealing material.

折り畳み式止水装置の水平方向の両端部は壁又は柱11,12の凹みにシール材を介して当たることで、水平方向及び後方への移動を阻止される。壁又は柱に適宜な凹みが無い場合は係止部材としてL字型部材111,112を壁又は柱或いは床へ接着剤などで固着するなどして自主工事での設置が可能である。   Both ends in the horizontal direction of the foldable waterstop device are prevented from moving in the horizontal direction and rearward by contacting the recesses of the walls or pillars 11 and 12 via the sealant. If the wall or column does not have an appropriate recess, the L-shaped members 111 and 112 can be fixed to the wall or column or floor with an adhesive or the like as a locking member, and can be installed in the independent construction.

壁又は柱に両端を固定されたロープ15で、前面に凸になった結合部5,6へ圧力を加える。ロープ15は加圧部材である。ロープ15と結合部5,6との間の摩擦を無視するとロープによる加圧はロープ15はロープを締め付けることで結合部5,6を後方へ加圧する。加圧された結合部5は、止水板1及び止水板2へ応力を伝え、加圧された結合部6は、止水板3及び止水板4へ応力を伝える。ロープによる加圧で生じた力は結合部に繋がれた止水板に加わる。   Pressure is applied to the joints 5 and 6 that are convex on the front surface with the rope 15 having both ends fixed to the wall or column. The rope 15 is a pressure member. When the friction between the rope 15 and the connecting portions 5 and 6 is ignored, the rope 15 pressurizes the connecting portions 5 and 6 backward by tightening the rope. The pressurized coupling portion 5 transmits stress to the waterstop plate 1 and the waterstop plate 2, and the pressurized coupling portion 6 transmits stress to the waterstop plate 3 and the waterstop plate 4. The force generated by the pressure applied by the rope is applied to the water stop plate connected to the joint.

ロープを絞めることで、結合部5及び結合部6には、主に後方へ力が印加され、止水板を介して壁または柱11,12或いは、L字型部材111,112により受け止められる。また、結合部5に印加された力は止水板1,2へ伝達されると向かい合う止水板1及び止水板2のなす後方の角度を開く方向へ変換される。同様に、結合部6に印加された力は止水板3,4へ伝達されると向かい合う止水板3及び止水板4のなす後方の角度を開く方向へ変換される。   By squeezing the rope, a force is mainly applied to the coupling portion 5 and the coupling portion 6 in the rearward direction and is received by the walls or pillars 11 and 12 or the L-shaped members 111 and 112 through the water stop plate. Further, when the force applied to the coupling portion 5 is transmitted to the water stop plates 1 and 2, the force is converted to a direction in which the rear angle formed by the water stop plate 1 and the water stop plate 2 facing each other is opened. Similarly, when the force applied to the coupling portion 6 is transmitted to the water stop plates 3, 4, the force is converted in a direction to open the rear angle formed by the water stop plate 3 and the water stop plate 4 facing each other.

そうすると、結合部5及び結合部6の間の距離を狭める方向へ応力が加わって、水平方向へ展開している折り畳み式止水装置の水平方向の幅が狭まることになり、止水装置の両端部を壁又は柱11,12へ押し付ける圧力が減少するので好ましくない。そこで、向かい合う止水板2及び止水板3のなす前方の角度が所定の角度よりも小さくならないように角度保持部材17を、止水板2及び止水板3のなす前方の角度へ設ける。ここで、角度保持部材は所定の角度よりも広がらないように用いることもできる。角度保持部材を形態対維持部材として適宜に用いることで止水装置の全体形態を維持することができる。   If it does so, stress will be added to the direction which narrows the distance between the coupling | bond part 5 and the coupling | bond part 6, and the width | variety of the horizontal direction of the folding-type water stop apparatus currently developed to the horizontal direction will become narrow, and both ends of a water stop apparatus Since the pressure which presses a part against a wall or the pillars 11 and 12 reduces, it is not preferable. Therefore, the angle holding member 17 is provided at the front angle formed by the water stop plate 2 and the water stop plate 3 so that the front angle formed by the water stop plate 2 and the water stop plate 3 facing each other is not smaller than a predetermined angle. Here, the angle holding member can also be used so as not to be wider than a predetermined angle. The entire form of the water stop device can be maintained by appropriately using the angle holding member as the form pair maintaining member.

次に、図2に示すのは加圧部材としてベルト150,160を用い、止水装置が後方へ移動しないように、折り畳み式止水装置の後部へ移動防止部材18を設けた場合である。ベルト150,160を締め付けるとベルトの長さを減らす方向すなわち後方へ力が掛かるので折り畳み式止水装置を後方へ移動させようとする。その結果、止水装置の両端部は壁又は柱11,12やL字材111,112に当たり後方への移動を妨げられるが結合部7は後方へ移動し、それに伴って止水板2及び止水板3の前方で作る角度が小さくなり折り畳み式止水装置の水平方向の寸法が減少して止水機能が損なわれる。このL字部材は止水装置の端部を係止する係止部材であり、止水装置の後方への移動を防止するとともに全体形態を維持する。   Next, FIG. 2 shows a case where the belts 150 and 160 are used as the pressure members, and the movement preventing member 18 is provided at the rear of the foldable water stop device so that the water stop device does not move backward. When the belts 150 and 160 are tightened, a force is applied in a direction that reduces the length of the belt, that is, backward, so that the folding water stop device is moved backward. As a result, both ends of the water stop device hit against the walls or pillars 11 and 12 and the L-shaped members 111 and 112 and are prevented from moving backward, but the connecting portion 7 moves backward, and accordingly, the water stop plate 2 and the water stop plate 2 are stopped. The angle made in front of the water plate 3 is reduced, the horizontal dimension of the folding water stop device is reduced, and the water stop function is impaired. This L-shaped member is a locking member that locks the end portion of the water stop device, and prevents the water stop device from moving rearward and maintains the entire form.

そこで、結合部7の後方への移動を防止する移動防止部材18を壁又は柱11,12の間へ装着してベルト150,160で張力を加えた際の折り畳み式止水装置の水平方向の幅の減少が起こらないようにする。実施する場合はベルトをゴムのような弾性体で構成することが好適である。また、弾性体として伸長ばねを用いても良い。ここで移動防止部材18は結合部7に当たる部分に凹みをつけることで止水装置の全体形態を維持するかんぬきの働きをする。   Therefore, when the movement preventing member 18 for preventing the connecting portion 7 from moving backward is mounted between the walls or the pillars 11 and 12 and tension is applied by the belts 150 and 160, the folding water stop device in the horizontal direction is arranged. Avoid width reduction. When implemented, the belt is preferably made of an elastic material such as rubber. Further, an extension spring may be used as the elastic body. Here, the movement preventing member 18 functions as a pin for maintaining the overall configuration of the water stop device by forming a dent in a portion corresponding to the coupling portion 7.

次に図3に示すのは止水板1及び止水板2間の間隔を広げるように働く板間拡大部材19と、止水板3及び止水板4間の間隔を広げるように働く板間拡大部材20を備えた折り畳み式止水装置である。折り畳み式止水装置の両端は板間拡大部材19,20により壁又は柱11,12に強く押し付けられる。この場合、板間拡大部材19,20が加圧部材となる。板間拡大部材19,20は突っ張り棒のように圧縮ばねを用いて止水板1と止水板2及び止水板3と止水板4の間の距離を広げるように設置する。   Next, FIG. 3 shows a plate-to-plate expansion member 19 that works to widen the space between the water stop plate 1 and the water stop plate 2 and a plate that works to widen the space between the water stop plate 3 and the water stop plate 4. It is a foldable water stop device provided with a space expanding member 20. Both ends of the foldable water stop device are strongly pressed against the walls or pillars 11 and 12 by the interplate expansion members 19 and 20. In this case, the inter-plate expansion members 19 and 20 are pressure members. The interplate expansion members 19 and 20 are installed so as to widen the distance between the waterstop plate 1 and the waterstop plate 2 and between the waterstop plate 3 and the waterstop plate 4 using a compression spring like a tension rod.

折り畳み式止水装置は、床や地面の上に広げられるので、その下端は床や地面にシール材を介して接する。シール材として発泡材を用いた場合はその止水性能を確保するために圧縮することが必要であるが折り畳み式止水装置の自重がシール材の圧縮に十分な大きさであれば下方への加圧は不要である。しかしながら、下方への圧力が不足する場合には、図5に示す下方加圧用水袋50、52を用いる。水袋には、止水板に係止する係止具51が設けられこれを止水板の上端に掛けて水を入れることで所要の下方圧力を得ることができる。水袋は保持用の穴の開いた合成樹脂製の袋が好適で、この穴に係止具としてのS字具の一端を引っ掛け他端を止水板の上端へ引っ掛けることで下方への圧力を得ることができる。また、この袋は丈夫な布で作り中に薄手のビニール袋を入れても良い。   Since the foldable water stop device is spread on the floor or the ground, the lower end thereof is in contact with the floor or the ground via a sealing material. When foaming material is used as the sealing material, it is necessary to compress it to ensure its water stopping performance, but if the weight of the foldable water stopping device is large enough to compress the sealing material, No pressurization is necessary. However, when the downward pressure is insufficient, the downward pressurizing water bags 50 and 52 shown in FIG. 5 are used. The water bag is provided with a locking tool 51 for locking to the water stop plate, and the required downward pressure can be obtained by putting this on the upper end of the water stop plate and putting water. The water bag is preferably a synthetic resin bag with a holding hole, and the hole is hooked with one end of the S-shaped tool as a locking tool, and the other end is hooked with the upper end of the water stop plate. Can be obtained. The bag may be made of a strong cloth and a thin plastic bag may be put in it.

図4に示すように、止水板のなす角度を適宜に取ることで止水された状態でドアの開閉が可能な状態にできる展開式止水装置を構成することができる。加圧部材であるロープ15が水の来る前方へ凸になった止水板101と止水板102の結合部10、止水板102と止水板103の結合部11を後方へ押すように加圧する。水圧により結合部は向かい合う止水板の作る後方の角度が減少するような力が働くので所定の角度以下にならないように角度保持部材171,172を用いる。また、加圧部材として、壁又は柱110と止水板101及び壁又は柱120と止水板103との間に弾性を持つベルトを張って加圧部材としても良い。   As shown in FIG. 4, it is possible to configure a deployable water stop device that can open and close the door while the water is stopped by appropriately taking an angle formed by the water stop plate. The rope 15 as the pressurizing member pushes the joint portion 10 between the water stop plate 101 and the water stop plate 102 and the joint portion 11 between the water stop plate 102 and the water stop plate 103 which are convex toward the front where the water comes. Pressurize. The angle holding members 171 and 172 are used so as not to be less than a predetermined angle because a force that reduces the rear angle formed by the water blocking plates facing each other works due to the water pressure. Further, as the pressure member, an elastic belt may be stretched between the wall or column 110 and the water stop plate 101 and between the wall or column 120 and the water stop plate 103 to form the pressure member.

展開式止水装置の両端部は壁又は柱11,12に固定された係止部材111,112に当たり、水平方向及び後方へ力を加える。このように構成することで扉13の開閉ができる余地を確保して止水を実現することができる。   Both ends of the deployable water stop device hit the locking members 111 and 112 fixed to the walls or pillars 11 and 12, and apply force in the horizontal direction and rearward. By comprising in this way, the room which can open and close the door 13 is ensured, and water stop can be implement | achieved.

図6は止水板の角部分にシール材を重ねて使用する様子を示したものである。角の部分は隙間ができやすいのでシール材の厚みを大きくして止水板と床と壁又は柱の継ぎ目になじみやすいようにする。   FIG. 6 shows a state in which a sealing material is used on the corner portion of the water stop plate. Since the corner portion is easy to create a gap, the thickness of the sealing material is increased so that it is easy to become familiar with the joint between the water stop plate and the floor and the wall or the pillar.

次に、図7及び図8を用いて、図の下方から水圧が掛かる場合の応力の掛かり方の説明をする。水圧は、止水板の水につかっている部分に対し深さに応じた力を直角に止水板に加える。   Next, how to apply stress when water pressure is applied from below in the figure will be described with reference to FIGS. 7 and 8. The water pressure applies a force corresponding to the depth to the water stop plate at a right angle to the portion of the water stop plate that is in contact with water.

図7を用いて水の来る方向に対して凸になった止水板に加わる水の力による影響を説明する。止水板1又は止水板3の水に浸かっていつ部分に分布している力を止水板の中心へ加えられる力F1又はF3で置き換える。水圧F1、F3により止水板1や止水板3が受けた力F10又はF30は力の平行四辺形により水平方向の力F12又はF32と前後方向の力F11又はF31へ分解することができる。同様に、止水板2又は止水板4へ加わる水圧をF2又はF4すると止水板の受ける力F20又はF40は力の平行四辺形により水平方向の力F22又はF42と前後方向の力F21又はF41へ分解することができる。   The influence by the force of the water added to the water stop board which became convex with respect to the direction where water comes is demonstrated using FIG. The force distributed in the portion immersed in the water of the water stop plate 1 or the water stop plate 3 is replaced with the force F1 or F3 applied to the center of the water stop plate. The force F10 or F30 received by the waterstop plate 1 or the waterstop plate 3 by the water pressures F1 and F3 can be decomposed into a horizontal force F12 or F32 and a front-rear force F11 or F31 by the parallelogram of the force. Similarly, when the water pressure applied to the water stop plate 2 or the water stop plate 4 is F2 or F4, the force F20 or F40 received by the water stop plate is a horizontal force F22 or F42 and a front-rear direction force F21 or It can be decomposed into F41.

止水板1又は止水板3及び止水板2又は止水板4に印加される水圧F1又はF3及びF2又はF4によって、止水板1又は止水板3及び止水板2又は止水板4は後方へ押される。同時に、2枚の止水板1又は止水板3及び止水板2又は止水板4は互いに近づく方向への力を受け、止水板1と止水板2の後方でなす角θ5及び止水板3と止水板4の後方でなす角θ6は減少することとなる。そこで、止水板1又は止水板3と止水板2又は止水板4の位置及び互いになす角度を水圧により変えられないための対策が必要になる。   By the water pressure F1 or F3 and F2 or F4 applied to the water stop plate 1 or the water stop plate 3 and the water stop plate 2 or the water stop plate 4, the water stop plate 1 or the water stop plate 3 and the water stop plate 2 or the water stop The plate 4 is pushed backward. At the same time, the two water stop plates 1 or 3 and the water stop plate 2 or the water stop plate 4 receive a force in a direction approaching each other, and an angle θ5 formed behind the water stop plate 1 and the water stop plate 2 and The angle θ6 formed behind the water stop plate 3 and the water stop plate 4 decreases. Therefore, it is necessary to take measures to prevent the position of the water stop plate 1 or the water stop plate 3 and the water stop plate 2 or the water stop plate 4 and the angle formed therebetween from being changed by water pressure.

次に図8を用いて水の来る方向に対して凹になった止水板に加わる水の力による影響を説明する。止水板の水に浸かっている部分への分布している力を止水板の中心へ加えられる力で置き換える。水圧F2により止水板2が受けた力F20は力の平行四辺形により水平方向の力F22と前後方向の力F21へ分解することができる。同様に、止水板3へ加わる水圧をF3とすると止水板の受ける力F30は力の平行四辺形により水平方向の力F32と前後方向の力F31へ分解することができる。   Next, the influence of the force of water applied to the water stop plate that is recessed with respect to the direction in which water comes will be described using FIG. Replacing the distributed force on the part of the waterstop that is immersed in water with the force applied to the center of the waterstop. The force F20 received by the water stop plate 2 by the water pressure F2 can be decomposed into a horizontal force F22 and a front-rear force F21 by the parallelogram of the force. Similarly, if the water pressure applied to the water stop plate 3 is F3, the force F30 received by the water stop plate can be decomposed into a horizontal force F32 and a front-rear direction force F31 by the parallelogram of the force.

止水板2及び止水板3に印加される水圧F2及びF3によって、止水板2及び止水板3は後方へ押される。同時に、2枚の止水板は互いに離れる方向への力を受け、止水板2と止水板3の後方でなす角θ7は増加することとなる。そこで、止水板2と止水板3の位置及び互いになす角度を水圧により変えられないための対策が必要になるる。   The water stop plate 2 and the water stop plate 3 are pushed backward by the water pressures F2 and F3 applied to the water stop plate 2 and the water stop plate 3. At the same time, the two water stop plates receive a force in a direction away from each other, and the angle θ7 formed behind the water stop plate 2 and the water stop plate 3 increases. Therefore, it is necessary to take measures to prevent the position of the water stop plate 2 and the water stop plate 3 and the angle formed therebetween from being changed by the water pressure.

上記の説明で水圧によって折り畳み式止水装置は後方へ押されることと、向かい合う2枚の止水板の間の角度が変化させられることがわかる。また、止水装置の両端部にはシール材が貼られており、止水性能を確保するためにはシール材を壁または柱11,12あるいは、壁または柱11,12に固定される係止部材111,112へ圧接させる必要がある。   From the above description, it can be seen that the folding water stop device is pushed backward by the water pressure and that the angle between the two water stop plates facing each other is changed. Moreover, the sealing material is affixed to both ends of the water stop device, and in order to ensure the water stop performance, the seal member is fixed to the wall or column 11 or 12 or the wall or column 11 or 12. It is necessary to press-contact the members 111 and 112.

図9を用いて、水圧による移動などへの対策方法を説明する。水圧による後方への移動の阻止は壁または柱11,12あるいは壁または柱11,12に固定される係止部材111,112に止水装置の横方向の端部を当てることで行う。壁または柱11,12に固定される係止部材111,112に当たっている止水装置の横方向の端部については後方への移動を防止することができる。しかし、結合部7についてはその後方に支えるものが無い場合は水圧により後方へ移動する。この動きを直接防止するのが、図2の移動防止部材18である。移動防止部材18は所定の剛性を有する棒状のものが好適で、その両端部を壁または柱11,12に固定することで結合部7の後方への移動を防止することができる。   With reference to FIG. 9, a countermeasure method against movement due to water pressure will be described. Prevention of the backward movement due to water pressure is performed by applying the lateral end of the water stop device to the wall or column 11, 12 or the locking members 111, 112 fixed to the wall or column 11, 12. About the edge part of the horizontal direction of the water stop apparatus which has contacted the locking members 111 and 112 fixed to the wall or the pillars 11 and 12, it can prevent a movement to back. However, when there is nothing to support behind the connecting portion 7, the connecting portion 7 moves backward due to water pressure. The movement preventing member 18 in FIG. 2 directly prevents this movement. The movement preventing member 18 is preferably a rod-shaped member having a predetermined rigidity, and the movement of the connecting portion 7 to the rear can be prevented by fixing both end portions thereof to the walls or columns 11 and 12.

図9において壁または柱11、12に固定された加圧部材となるロープにより前方へ凸になっている結合部5及び結合部6を加圧した場合を説明する。ここでロープ15と止水装置との間の摩擦を無視する。結合部5において、ロープ15は移動しないので張力F50と張力F51とはその大きさが等しい。F50とF51の合成力はF50とF51を両辺とする平行四辺形の対角線となるF52である。ここで、F52とF50及びF52とF51との間の角度αは等しい。   A case will be described in which the coupling portion 5 and the coupling portion 6 that are convex forward are pressed by a rope serving as a pressure member fixed to the walls or columns 11 and 12 in FIG. 9. Here, the friction between the rope 15 and the water stop device is ignored. Since the rope 15 does not move in the coupling portion 5, the tension F50 and the tension F51 are equal in size. The combined force of F50 and F51 is F52 which is a parallelogram diagonal line with F50 and F51 on both sides. Here, the angles α between F52 and F50 and between F52 and F51 are equal.

そして、ロープ15による加圧で生じたF52は水平方向の壁又は柱12へ向けた分力F54と後方への分力F53になる。ここで、止水板1には水圧によって壁または柱12へ向けた力F12(図7、図8を参照)が働く。止水板2には水圧によって壁または柱11へ向けた力F22(図7、図8を参照)が働く。F12とF22は大きさが同じで向きが反対なので、結合部での角度が保たれていれば互いに打ち消しあう。   Then, F52 generated by the pressurization by the rope 15 becomes a component force F54 toward the horizontal wall or column 12 and a component force F53 backward. Here, a force F <b> 12 (see FIGS. 7 and 8) acting on the wall or column 12 by the water pressure acts on the water stop plate 1. A force F <b> 22 (see FIGS. 7 and 8) acting on the wall or the column 11 is applied to the water stop plate 2 by water pressure. Since F12 and F22 have the same size and opposite directions, they cancel each other if the angle at the joint is maintained.

同様に、結合部6についてもロープ15は移動しないので張力F60と張力F61とはその大きさが等しい。F60とF61の合成力はF60とF61を両辺とする平行四辺形の対角線となるF62である。ここで、F62とF60及びF62とF61との間の角度βは等しい。   Similarly, since the rope 15 does not move with respect to the connecting portion 6, the tension F60 and the tension F61 are equal in size. The combined force of F60 and F61 is F62 which is a parallelogram diagonal line with F60 and F61 on both sides. Here, the angles β between F62 and F60 and between F62 and F61 are equal.

そして、ロープ15による加圧で生じたF62は水平方向の壁又は柱11へ向けた分力F64と後方への分力F63になる。ここで、止水板3には水圧によって壁または柱12へ向けた力F32(図7、図8を参照)が働く。止水板4には水圧によって壁または柱11へ向けた力F42(図7、図8を参照)が働く。F32とF42は大きさが同じで向きが反対なので、結合部での角度が保たれていれば互いに打ち消しあう。   Then, F62 generated by the pressurization by the rope 15 becomes a component force F64 directed to the horizontal wall or column 11 and a component force F63 backward. Here, a force F32 (see FIGS. 7 and 8) directed to the wall or the column 12 is applied to the water stop plate 3 by water pressure. A force F42 (see FIGS. 7 and 8) directed to the wall or column 11 is applied to the water stop plate 4 by water pressure. Since F32 and F42 have the same size and opposite directions, they cancel each other if the angle at the joint is maintained.

そこで結合部で止水板が作る角度を保持するために角度保持部材17を用いる。結合部7の後方への移動と止水板2及び止水板3の前方でなす角θ7の減少は対応しているので結合部17の前方に止水板2及び止水板3により作られる角θ7の減少を角度保持部材により防止することで結合部7の後方への移動を防止することができる。角度保持部材は必要に応じて、他の結合部へ設置してもよい。   Therefore, the angle holding member 17 is used to hold the angle formed by the water stop plate at the coupling portion. Since the rearward movement of the coupling portion 7 corresponds to the decrease in the angle θ7 formed in front of the water stop plate 2 and the water stop plate 3, the water stop plate 2 and the water stop plate 3 are formed in front of the connection portion 17. By preventing the angle θ7 from being reduced by the angle holding member, it is possible to prevent the coupling portion 7 from moving backward. You may install an angle holding member in another coupling | bond part as needed.

上述のように、折り畳み式止水装置において、加圧部材としてロープ15を用い、後方への移動を防止する角度保持部材17を用いることで図1に示すような折り畳み式止水装置を構成することができる。   As described above, in the foldable water stop device, the foldable water stop device as shown in FIG. 1 is configured by using the rope 15 as the pressure member and using the angle holding member 17 that prevents the rearward movement. be able to.

次に図10を用いて図4で説明した展開式止水装置における力の関係を説明する。止水板101には水圧F7が加わる。加わった力F70は水平方向の分力F72と後方への分力F71に分解することができる。また、止水板103に加わる水圧F9による力F90は水平方向への分力F92と後方への分力F91へ分解することができる。水圧F7による水平方向への分力F72と水圧F9による水平方向への分力F92とは、止水装置が剛体であれば大きさが等しく方向が逆なので互いに打ち消しあう。   Next, the relationship between forces in the deployable water stop device described in FIG. 4 will be described with reference to FIG. A water pressure F7 is applied to the water stop plate 101. The applied force F70 can be decomposed into a horizontal component force F72 and a backward component force F71. Further, the force F90 due to the water pressure F9 applied to the water stop plate 103 can be decomposed into a component force F92 in the horizontal direction and a component force F91 in the rear. The horizontal component force F72 due to the water pressure F7 and the horizontal component force F92 due to the water pressure F9 cancel each other because the size is equal and the direction is opposite if the water stop device is a rigid body.

また、止水板102へ加わる水圧F8による力は後方へ向くが止水板101と止水板102へ伝達されて係止部材111、112により移動を防止される。ここで、加圧部材のロープ15により結合部10と結合部11を前方から締め付けるように張力を加える。止水装置とロープの間の摩擦は無視する。   Further, although the force by the water pressure F8 applied to the water stop plate 102 is directed rearward, it is transmitted to the water stop plate 101 and the water stop plate 102 and is prevented from moving by the locking members 111 and 112. Here, tension is applied so that the coupling portion 10 and the coupling portion 11 are tightened from the front by the rope 15 of the pressure member. Ignore the friction between the water stop and the rope.

結合部10を加圧するロープの張力F101とF102とは釣り合っているので大きさが等しくなるF101とF102との合成力F10はF101とF102の大きさが等しいのでF10とF101、F10とF102との間の角度は共にσとなる。   Since the tension F101 and F102 of the rope that pressurizes the coupling portion 10 is balanced, the combined force F10 of F101 and F102 that are equal in magnitude is equal to the magnitude of F101 and F102, so that F10 and F101, F10 and F102 Both angles are σ.

同様に、結合部11を加圧するロープの張力F111とF112とは釣り合っているので大きさが等しくなるF111とF112との合成力F11はF111とF112の大きさが等しいのでF11とF111、F11とF112との間の角度は共にδとなる。   Similarly, the tension F111 and F112 of the rope that pressurizes the coupling portion 11 is balanced, so that the combined force F11 of F111 and F112 that are equal in magnitude is the same as F111 and F112, so that F11, F111, and F11 Both angles with F112 are δ.

ロープによる加圧で生じた水平方向の分力F104とF114は大きさが等しく向きが逆なので打ち消しあう。そうするとロープ15の加圧による力は後方への力F100とF110を加えたものになる。すべての後方への力は係止具111、112により受け止められ、止水装置の両端に固着されたシール材を圧迫して止水性能を確保する。   Since the horizontal component forces F104 and F114 generated by the pressure applied by the rope are equal in size and opposite in direction, they cancel each other. Then, the force due to the pressurization of the rope 15 is the sum of the backward forces F100 and F110. All the backward force is received by the locking members 111 and 112, and the sealing material fixed to both ends of the water stop device is pressed to ensure water stop performance.

次に、図11を用いてベルト150,160によって止水装置の両端の止水板を壁又は柱へ引きつける場合の力の説明をする。止水板1乃至4にはそれぞれ水による力F1乃至F4が加わる。さらに、ベルト150により止水板1が壁又は柱110へ引きつけられ、ベルト160により止水板4が壁又は柱120へ引きつけられる。   Next, the force in the case of attracting the water stop plates at both ends of the water stop device to the wall or the column by the belts 150 and 160 will be described with reference to FIG. Water stops F1 to F4 are applied to the water stop plates 1 to 4, respectively. Further, the water stop plate 1 is attracted to the wall or the pillar 110 by the belt 150, and the water stop plate 4 is attracted to the wall or the pillar 120 by the belt 160.

ベルト150の張力F150は止水板1に加わって水平方向の力F152と後方への力F151へ分解される。また、ベルト160の張力F160は止水板4に加わって水平方向の力F162と後方への力F161へ分解される。ベルトの張力による後方への力と水圧による後方への力は、移動防止部材18と壁又は柱110、120或いは係止部材111、112により受け止められ止水装置の後方への移動が防止される。   The tension F150 of the belt 150 is applied to the water stop plate 1 and decomposed into a horizontal force F152 and a rearward force F151. Further, the tension F160 of the belt 160 is applied to the water blocking plate 4 and is decomposed into a horizontal force F162 and a rearward force F161. The backward force due to the tension of the belt and the backward force due to the water pressure are received by the movement preventing member 18 and the wall or pillars 110 and 120 or the locking members 111 and 112 to prevent the backward movement of the water stop device. .

折り畳み式止水装置の撤去は、設置と逆の手順で撤去されればよい。ロープで加圧している場合はロープを外し、下方への加圧に水を用いている場合は水袋を除去する。止水板以外の部材が取り外された後に、止水板を折りたたんで収納する。   The removal of the foldable water stop device may be removed in the reverse order of the installation. Remove the rope if pressure is applied with a rope, and remove the water bag if water is used for downward pressure. After the members other than the water stop plate are removed, the water stop plate is folded and stored.

また、前記実施形態では、シール材60として独立気泡の柔軟な材料を用いたが、ポリブテン樹脂及び合成樹脂接着剤を基材とするパテでも良い。シール材60は、加圧されることで変形して対象物に密着するとともに、変形後の形状を維持するような性質を有していればよく、例えば、軟性を有する(硬化剤を含まない)その他の樹脂粘土等であってもよいし、発泡ウレタン等の発泡性の部材であってもよい。即ち、止水材の床に接する面に沿うようにスプレーによって発泡ウレタンを設け、そこへ止水装置を載せてとで止水手段としてもよい。   In the above embodiment, a flexible material having closed cells is used as the sealing material 60. However, a putty based on a polybutene resin and a synthetic resin adhesive may be used. The sealing material 60 only needs to have a property of being deformed by being pressurized and closely contacting the object and maintaining the shape after the deformation. For example, the sealing material 60 has flexibility (does not include a curing agent). ) Other resin clays or foaming members such as urethane foam may be used. That is, it is good also as a water stop means by providing foaming urethane by spraying along the surface which touches the floor of a water stop material, and mounting a water stop apparatus there.
