Description

本発明は、目地状部分の止水部材及び目地状部分の止水構造に関する。 The present invention relates to a water blocking member of a joint-shaped portion and a water blocking structure of the joint-shaped portion.

コンクリート構造体、例えば防火水槽や貯水槽などのコンクリート製水槽、コンクリート擁壁やコンクリート製法面など斜面などの壁構造体、などにおいて、経年劣化などでヒビ(亀裂)が発生した場合の修復工事には、そのヒビの隙間内にモルタルなどを注入する方法や、ヒビの隙間内に水膨張性樹脂素材の紐状シール材を圧入したり、水膨張性樹脂素材を押し当てたりするなどの対処方法が採られている。 For repair work when cracks occur due to aging deterioration in concrete structures such as concrete water tanks such as fireproof water tanks and water storage tanks, and wall structures such as slopes such as concrete retaining walls and concrete slopes. Is a method of injecting mortar or the like into the gap between the cracks, a method of pressing a string-shaped sealing material of a water-expandable resin material into the gap of the crack, or a method of pressing the water-expandable resin material. Has been taken.

特許文献1には、地中に形成されたコンクリート構造体の壁面等に発生したクラック等の漏水部を補修するための地中コンクリート構造体の漏水部止水構造が開示されている。コンクリート構造体の表面には、表面に発生した漏水部を塞ぐパッキンが設けられ、かつパッキンの背面側には、少なくともパッキンと同等以上の寸法を有し、コンクリート構造体に先端部を埋設される複数本のアンカーボルトによって押圧される加圧板が設けられる。 Patent Document 1 discloses a water leakage portion water blocking structure of an underground concrete structure for repairing a water leakage portion such as a crack generated on a wall surface or the like of a concrete structure formed in the ground. A packing is provided on the surface of the concrete structure to close the leaked portion generated on the surface, and the back side of the packing has at least the same size as the packing and the tip portion is embedded in the concrete structure. A pressure plate pressed by a plurality of anchor bolts is provided.

この地中コンクリート構造体の漏水部止水構造によれば、アンカーボルトに係止・押圧される加圧板によってパッキンがコンクリート構成体の表面に発生した漏水部に圧接・密着されることにより、漏水が確実に止水される。その場合、施工後、コンクリート構造体が種々の外力を受けてクラック(漏水部)の間隙が開くような状態となっても、パッキンがクラックの両側に強く密着されているものであるから、構造体内部への漏水を発生させることはない。 According to the water leakage part water blocking structure of this underground concrete structure, water leakage is caused by the packing being pressed and brought into close contact with the water leakage part generated on the surface of the concrete structure by the pressure plate locked and pressed by the anchor bolt. Is surely stopped. In that case, even if the concrete structure receives various external forces and the gaps of cracks (leakage parts) are opened after construction, the packing is strongly adhered to both sides of the cracks. It does not cause water leakage to the inside of the body.

特許第2605104号公報Japanese Patent No. 2605104

しかしながら、上記した地中コンクリート構造体の漏水部止水構造は、加圧板によってパッキンがヒビを覆うモルタル等に圧接・密着する。このため、ヒビを覆うモルタル等の止水工が圧接力・密着力により割れる場合がある。このような不具合は、パッキンが平板状の水膨張性材料であったりする場合に、膨張したパッキンがモルタル等を押圧するため、特に顕著となる。 However, in the above-mentioned water-stopping structure of the underground concrete structure, the packing is pressed and adhered to the mortar or the like covering the cracks by the pressure plate. For this reason, the water blocking work such as mortar that covers the cracks may be cracked due to the pressure contact force and the adhesion force. Such a problem becomes particularly remarkable when the packing is a flat plate-shaped water-expandable material because the expanded packing presses the mortar or the like.

本発明は上記状況に鑑みてなされたもので、その目的は、従来構造に比べさらに高い止水性能を得ることができる目地状部分の止水部材及び目地状部分の止水構造を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a water-stopping member for a joint-like portion and a water-stopping structure for the joint-like portion, which can obtain higher water-stopping performance as compared with a conventional structure. It is in.

本発明の請求項1記載の目地状部分の止水部材11は、構造体13の表面15に、目地25やヒビ17などの連続した線状の隙間部分となって開口する目地状部分を包囲して環状に形成され、前記表面15に密着するシール部材19と、
前記シール部材19を挟んで前記表面15の反対側で前記シール部材19に密着し、前記シール部材19より外側に張り出す周縁部27を有して前記目地状部分(25,17)を覆う閉塞部材21と、
前記閉塞部材21の前記周縁部27に周方向の複数箇所で配置されて一端側が前記構造体13に固着し、他端側が前記周縁部27を貫通して前記閉塞部材21と前記表面15とで前記シール部材19を挟持して前記閉塞部材21を前記表面15に固定する固定部材23と、
を具備することを特徴とする。
Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The water-stopping member 11 for a joint portion according to claim 1 of the present invention surrounds a joint portion that opens as a continuous linear gap portion such as a joint 25 or a crack 17 on the surface 15 of the structure 13. The sealing member 19 which is formed in an annular shape and is in close contact with the surface 15.
A closure that is in close contact with the seal member 19 on the opposite side of the surface 15 across the seal member 19 and has a peripheral edge portion 27 that projects outward from the seal member 19 and covers the joint-like portions (25, 17). Member 21 and
The closing member 21 is arranged at a plurality of points in the circumferential direction on the peripheral edge portion 27, one end side is fixed to the structure 13, and the other end side penetrates the peripheral edge portion 27 to form the closing member 21 and the surface 15. A fixing member 23 that sandwiches the seal member 19 and fixes the closing member 21 to the surface 15.
It is characterized by having.

この目地状部分の止水部材11では、環状に形成されて構造体13に密着するシール部材19により、目地状部分が包囲される。目地状部分は、構造体13の表面15に開口する。この目地状部分は、例えばコンクリート製水槽のヒビ17等とすることができる。この他、目地状部分は、例えばコンクリート製水槽などの目地25であってもよい。この場合、目地25は、貯水域と通じる経路が止水構造で予め水密シールされていてもよい。
シール部材19を挟んで構造体13の表面15の反対側には、閉塞部材21がシール部材19に密着して設けられる。閉塞部材21は、シール部材19より外側に張り出す周縁部27を有して目地状部分を覆う。閉塞部材21の周縁部27には、周方向の複数箇所で固定部材23が配置される。固定部材23は、一端側が構造体13に固着される。固定部材23の他端側は、周縁部27を貫通して、閉塞部材21を構造体13の表面15に固定する。つまり、シール部材19は、閉塞部材21と構造体13の表面15とで挟持される。シール部材19は、閉塞部材21と構造体13の表面15とに密着することで、環状の内側に密閉空間37を形成する。構造体13は、表面15の目地状部分が、この密閉空間37に臨んで配置される。
目地状部分は、密閉空間37に臨んで配置されるので、シール部材19の厚み分、閉塞部材21から離間して配置される。これにより、目地状部分は、閉塞部材21により押圧されなくなる。すなわち、目地状部分や、目地25を塞いだ既存の水密シール構造を損ねる(圧壊等する)ことがない。これに加え、新たな密閉空間37を形成し、目地状部分や目地25を塞いだ既存の水密シール構造に、ヒビ17等が発生した場合に生じる漏水を、二重の水密シール構造より止水する作用を得ることができる。その結果、漏水をより効果的に抑制することができるようになる。
In the water blocking member 11 of the joint-shaped portion, the joint-shaped portion is surrounded by the seal member 19 which is formed in an annular shape and is in close contact with the structure 13. The joint-like portion opens on the surface 15 of the structure 13. This joint-like portion can be, for example, a crack 17 in a concrete water tank or the like. In addition, the joint-like portion may be a joint 25 such as a concrete water tank. In this case, the joint 25 may be watertightly sealed in advance with a water-stop structure on the path leading to the water storage area.
A closing member 21 is provided in close contact with the sealing member 19 on the opposite side of the surface 15 of the structure 13 with the sealing member 19 interposed therebetween. The closing member 21 has a peripheral edge portion 27 projecting outward from the sealing member 19 and covers the joint-like portion. Fixing members 23 are arranged at a plurality of locations in the circumferential direction on the peripheral edge portion 27 of the closing member 21. One end of the fixing member 23 is fixed to the structure 13. The other end side of the fixing member 23 penetrates the peripheral edge portion 27 and fixes the closing member 21 to the surface 15 of the structure 13. That is, the seal member 19 is sandwiched between the closing member 21 and the surface 15 of the structure 13. The seal member 19 is in close contact with the closing member 21 and the surface 15 of the structure 13 to form a closed space 37 inside the annular shape. In the structure 13, the joint-like portion of the surface 15 is arranged so as to face the closed space 37.
Since the joint-like portion is arranged so as to face the closed space 37, it is arranged so as to be separated from the closing member 21 by the thickness of the sealing member 19. As a result, the joint-like portion is not pressed by the closing member 21. That is, the joint-like portion and the existing watertight seal structure that closes the joint 25 are not damaged (crushed or the like). In addition to this, the double watertight seal structure prevents water leakage that occurs when cracks 17 or the like occur in the existing watertight seal structure that forms a new sealed space 37 and closes the joints and joints 25. It is possible to obtain the action of As a result, water leakage can be suppressed more effectively.

水膨張性材料からなる水膨張部51と、
前記水膨張性材料を含まない非水膨張部53と、からなることを特徴とする。
The joint-shaped portion water-stopping member 11 according to claim 2 of the present invention is the joint-shaped portion water-stopping member 11 according to claim 1 and the seal member 19.
A water expansion part 51 made of a water expansion material and
It is characterized by comprising a non-water-expanding portion 53 that does not contain the water-expandable material.

この目地状部分の止水部材11では、シール部材19が、線状部材により無端環状となって形成される。線状部材は、長手方向に直交方向の断面形状が、中実や中空の円形状、中実の四角形状、台形状、六角形状、蒲鉾形状などとすることができる。ここで、線状部材は、断面形状の外側を水膨張性材料で形成し、断面形状の内側を非水膨張部53で形成することができる。このような二重構造の線状部材で形成したシール部材19は、外側の水膨張性材料により止水性能が得られるとともに、内側の非水膨張部53により長手方向の膨張が規制される。これにより、シール部材19は、位置ずれを抑制して、断面形における周方向に膨張することが可能となり、構造体13の表面15及び閉塞部材21に確実に密着し、良好な止水性能を得ることができる。 In the water blocking member 11 of the joint-shaped portion, the sealing member 19 is formed by a linear member in an endless annular shape. The cross-sectional shape of the linear member in the direction orthogonal to the longitudinal direction can be a solid or hollow circular shape, a solid square shape, a trapezoidal shape, a hexagonal shape, a semi-cylindrical shape, or the like. Here, the linear member can be formed of a water-expandable material on the outside of the cross-sectional shape and a non-water-expandable portion 53 on the inside of the cross-sectional shape. In the seal member 19 formed of such a double-structured linear member, water-stopping performance is obtained by the water-expandable material on the outside, and expansion in the longitudinal direction is regulated by the non-water-expandable portion 53 on the inside. As a result, the seal member 19 can suppress the misalignment and expand in the circumferential direction in the cross-sectional shape, and can be surely adhered to the surface 15 of the structure 13 and the closing member 21 to provide good water stopping performance.

本発明の請求項3記載の目地状部分の止水部材11は、請求項1または2に記載の目地状部分の止水部材11であって、
前記閉塞部材21が、前記表面15に沿う板状部材であることを特徴とする。
The joint-shaped water blocking member 11 according to claim 3 of the present invention is the joint-shaped water blocking member 11 according to claim 1 or 2.
The closing member 21 is a plate-shaped member along the surface 15.

この目地状部分の止水部材11では、閉塞部材21が、構造体13の表面15に沿う板状部材となる。表面15に沿うとは、平坦な表面15に対して平行となる場合、凹曲面(湾曲面)である表面15に対して湾曲面となって沿う場合の双方を含む。いずれの場合においても、閉塞部材21は、板状部材となることにより、目地状部分を覆う止水構造を構成した際に、構造体13の表面15からの突出距離を、ブロック状の部材で形成した場合に比べ小さくすることができる。 In the water blocking member 11 of the joint-shaped portion, the closing member 21 is a plate-shaped member along the surface 15 of the structure 13. The term "along the surface 15" includes both a case where the surface is parallel to the flat surface 15 and a case where the surface 15 is curved with respect to the concave curved surface (curved surface). In any case, the closing member 21 is a plate-shaped member, so that when a water-stopping structure covering the joint-shaped portion is formed, the protruding distance from the surface 15 of the structure 13 is determined by the block-shaped member. It can be made smaller than when it is formed.

本発明の請求項4記載の目地状部分の止水部材61は、請求項1〜3のいずれか一つに記載の目地状部分の止水部材11であって、
前記閉塞部材67が、前記シール部材の挟持方向における一部分を受け入れる溝部69を有することを特徴とする。
The joint-shaped water blocking member 61 according to claim 4 of the present invention is the joint-shaped water stopping member 11 according to any one of claims 1 to 3.
The closing member 67 is characterized by having a groove portion 69 that receives a part of the sealing member in the sandwiching direction.

この目地状部分の止水部材61では、閉塞部材67の構造体対向面39に、環状のシール部材(内側シール部材63、外側シール部材65)の挟持方向における一部分を受け入れる溝部69が形成される。従って、溝部69も環状に形成される。挟持方向における一部分とは、シール部材を形成している線状部材の断面形状における一部分である。つまり、溝部69に受け入れられたシール部材は、一部分を除く他部分が、閉塞部材67の構造体対向面39から構造体13の表面15に向かって突出する。この突出部分が、弾性変形可能な部分となる。弾性変形したシール部材は、弾性復元力が、溝部69や、構造体13の表面15への密着力となる。
シール部材は、溝部69に接着等して固定しておくことが好ましい。目地状部分の止水部材11は、シール部材を予め溝部69に固定しておくことにより、シール部材に位置ずれが生じにくくなる。また、搬送や設置時の作業性を良好にできる。
In the water blocking member 61 of the joint-like portion, a groove portion 69 for receiving a part of the annular seal member (inner seal member 63, outer seal member 65) in the sandwiching direction is formed on the structure facing surface 39 of the closing member 67. .. Therefore, the groove portion 69 is also formed in an annular shape. The part in the holding direction is a part in the cross-sectional shape of the linear member forming the seal member. That is, in the seal member received in the groove portion 69, other parts except a part project from the structure facing surface 39 of the closing member 67 toward the surface 15 of the structure 13. This protruding portion becomes a portion that can be elastically deformed. In the elastically deformed seal member, the elastic restoring force becomes the adhesion force to the groove portion 69 and the surface 15 of the structure 13.
It is preferable that the seal member is fixed to the groove 69 by adhesion or the like. By fixing the seal member to the groove portion 69 in advance, the water-stopping member 11 at the joint-like portion is less likely to be misaligned. In addition, workability during transportation and installation can be improved.

前記固定部材23が、前記閉塞部材21を介して前記シール部材19を所定の圧力で前記表面15に押し付けることを特徴とする。
The joint-shaped water blocking member 11 according to claim 5 of the present invention is the joint-shaped water blocking member 11 according to any one of claims 1 to 4.
The fixing member 23 is characterized in that the sealing member 19 is pressed against the surface 15 with a predetermined pressure via the closing member 21.

この目地状部分の止水部材11では、シール部材19が、密着している状態よりも大きな所定の加圧力により、構造体13の表面15及び閉塞部材21の構造体対向面39に押圧される。このシール部材19に対する所定の加圧力は、閉塞部材21を固定部材23により構造体13へ締結固定することにより得られる。シール部材19は、この所定の圧力により、弾性限度の範囲で弾性変形する。従って、シール部材19は、変形されることによって生じた内部応力(弾性復元力)により、より確実に構造体13の表面15、及び閉塞部材21の構造体対向面39に水密に密着する。 In the water blocking member 11 of the joint-like portion, the sealing member 19 is pressed against the surface 15 of the structure 13 and the structure facing surface 39 of the closing member 21 by a predetermined pressing force larger than the state in which they are in close contact with each other. .. A predetermined pressing force on the seal member 19 is obtained by fastening and fixing the closing member 21 to the structure 13 by the fixing member 23. The seal member 19 is elastically deformed within the elastic limit range by this predetermined pressure. Therefore, the seal member 19 more reliably adheres to the surface 15 of the structure 13 and the structure facing surface 39 of the closing member 21 in a watertight manner due to the internal stress (elastic restoring force) generated by the deformation.

FIG. 2 is a plan sectional view of the joint-shaped portion shown in FIG. 1 in an assembled state.
The water-stopping member 11 of the joint-like portion according to the present embodiment has a seal member 19, a closing member 21, and a fixing member 23 as main configurations.

シール部材19は、構造体13の表面15に開口して漏水の出口となる目地状部分を包囲して環状に形成され、構造体13の表面15に密着する。ここで、「目地状部分」とは、構造体13の表面15に開口する目地25(図3)やヒビ17などの連続した線状の隙間部分を言う。本実施形態では、目地状部分が、ヒビ17である。ヒビ17からは、構造体13の表面15と反対側の背面が臨む貯水域や地山に繋がる「みずみち」を伝う漏水が流れ出る、若しくは流れ出る可能性を有している。 The seal member 19 is formed in an annular shape by opening to the surface 15 of the structure 13 and surrounding the joint-like portion serving as the outlet for water leakage, and is in close contact with the surface 15 of the structure 13. Here, the “joint-like portion” refers to a continuous linear gap portion such as a joint 25 (FIG. 3) or a crack 17 that opens on the surface 15 of the structure 13. In the present embodiment, the joint-like portion is a crack 17. From the crack 17, there is a possibility that water leaks or flows out from the crack 17 along the "mizumichi" connected to the water storage area and the ground where the back surface opposite to the surface 15 of the structure 13 faces.

シール部材19は、水膨張性ゴムからなる。水膨張性ゴムの材質としては、例えばクロロプレンゴムを用いることができる。シール部材19は、リング状に形成される。シール部材19は、閉塞部材21に貼り付けてもよい。 The seal member 19 is made of water-expandable rubber. As the material of the water-expandable rubber, for example, chloroprene rubber can be used. The seal member 19 is formed in a ring shape. The seal member 19 may be attached to the closing member 21.

本実施形態において、目地状部分の止水部材11は、閉塞部材21が、構造体13の表面15に沿う平らな板状部材である。すなわち、閉塞部材21が構造体13の表面15に沿う平板で形成されている。 In the present embodiment, the water blocking member 11 of the joint-shaped portion is a flat plate-shaped member in which the closing member 21 is along the surface 15 of the structure 13. That is, the closing member 21 is formed of a flat plate along the surface 15 of the structure 13.

閉塞部材21は、シール部材19を挟んで、構造体13の表面15の反対側で、シール部材19に密着する。閉塞部材21は、シール部材19より外側に張り出す周縁部27を有する。従って、閉塞部材21は、シール部材19を挟んでヒビ17を覆う。 The closing member 21 is in close contact with the sealing member 19 on the opposite side of the surface 15 of the structure 13 with the sealing member 19 interposed therebetween. The closing member 21 has a peripheral edge portion 27 that projects outward from the sealing member 19. Therefore, the closing member 21 covers the crack 17 with the seal member 19 interposed therebetween.

固定部材23は、閉塞部材21の周縁部27に周方向の複数箇所で配置される。本実施形態において、固定部材23は、アンカーからなる。アンカーは、アンカー本体29と、ナット31とからなる。アンカー本体29は、構造体13の表面15に穿設された下穴33に挿入固定される。固定部材23は、一端側が構造体13に設けられた下孔に固着する。固定部材23は、他端側が周縁部27を貫通する。この固定部材23の他端側には、雄ねじ部が形成される。周縁部27を貫通した雄ねじ部には、ナット31が螺合される。これにより、固定部材23は、閉塞部材21と構造体13の表面15とでシール部材19を挟持して閉塞部材21を構造体13の表面15に固定する。 The fixing member 23 is arranged at a plurality of locations in the circumferential direction on the peripheral edge portion 27 of the closing member 21. In the present embodiment, the fixing member 23 is composed of an anchor. The anchor includes an anchor body 29 and a nut 31. The anchor body 29 is inserted and fixed in a pilot hole 33 formed in the surface 15 of the structure 13. One end of the fixing member 23 is fixed to a pilot hole provided in the structure 13. The other end of the fixing member 23 penetrates the peripheral edge portion 27. A male screw portion is formed on the other end side of the fixing member 23. A nut 31 is screwed into the male threaded portion penetrating the peripheral edge portion 27. As a result, the fixing member 23 sandwiches the seal member 19 between the closing member 21 and the surface 15 of the structure 13 to fix the closing member 21 to the surface 15 of the structure 13.

なお、アンカーは、棒芯打込み式、スリーブ打込み式、雌ねじ本体打込み式等のいずれであってもよい。棒芯打込み式、スリーブ打込み式では、予めナット31がアンカー本体29に螺合されていてもよい。雌ねじ本体打込み式では、本体打込み後、ボルトが螺合される。 The anchor may be any of a rod core driving type, a sleeve driving type, a female screw body driving type, and the like. In the rod core driving type and the sleeve driving type, the nut 31 may be screwed into the anchor body 29 in advance. In the female screw main body driving type, the bolt is screwed after the main body is driven.

閉塞部材21は、周縁部27と構造体表面15との間が、コーキング35によりさらに封止されてもよい。図2に示すように、コーキング35は、固定部材23を挟んでシール部材19の反対側の周縁部27と、表面15との間に充填、若しくは間隙を塞ぎ表出させないよに配置形成される。 The closing member 21 may be further sealed by caulking 35 between the peripheral edge portion 27 and the structure surface 15. As shown in FIG. 2, the caulking 35 is arranged and formed so as not to fill or close the gap between the peripheral edge portion 27 on the opposite side of the sealing member 19 and the surface 15 with the fixing member 23 interposed therebetween. ..

以上のように構成される目地状部分の止水部材11及び目地状部分の止水構造は、固定部材23が、閉塞部材21を介してシール部材19を所定の圧力で構造体13の表面15に押し付ける。本実施形態では、固定部材23がアンカー本体29及びナット31であるから、ナット31を締め付けることにより、閉塞部材21を介してシール部材19を所定の圧力で表面15に押し付けることができる。 In the water-stopping member 11 of the joint-shaped portion and the water-stopping structure of the joint-shaped portion configured as described above, the fixing member 23 presses the sealing member 19 via the closing member 21 at a predetermined pressure on the surface 15 of the structure 13. Press on. In the present embodiment, since the fixing member 23 is the anchor body 29 and the nut 31, the seal member 19 can be pressed against the surface 15 with a predetermined pressure via the closing member 21 by tightening the nut 31.

次に、上記した構成の作用を説明する。
本実施形態に係る目地状部分の止水部材11では、環状に形成されて構造体13に密着するシール部材19により、目地状部分が包囲される。目地状部分は、構造体13の表面15に開口する。この目地状部分は、例えばコンクリート製水槽のヒビ17等とすることができる。この他、目地状部分は、例えばコンクリート製水槽の目地25(図3)であってもよい。この場合、目地25は、貯水域と通じる経路が止水構造で水密シールされる。
Next, the operation of the above configuration will be described.
In the water-stopping member 11 of the joint-shaped portion according to the present embodiment, the joint-shaped portion is surrounded by the seal member 19 which is formed in an annular shape and is in close contact with the structure 13. The joint-like portion opens on the surface 15 of the structure 13. This joint-like portion can be, for example, a crack 17 in a concrete water tank or the like. In addition, the joint-like portion may be, for example, the joint 25 (FIG. 3) of the concrete water tank. In this case, the joint 25 is watertightly sealed with a watertight structure on the path leading to the water storage area.

シール部材19を挟んで表面15の反対側には、閉塞部材21がシール部材19に密着して設けられる。閉塞部材21は、シール部材19より外側に張り出す周縁部27を有してヒビ17を覆う。閉塞部材21の周縁部27には、周方向の複数箇所で固定部材23が配置される。固定部材23は、一端側が構造体13に固着される。固定部材23の他端側は、周縁部27を貫通して、閉塞部材21を構造体13の表面15に固定する。つまり、シール部材19は、閉塞部材21と構造体13の表面15とで挟持される。シール部材19は、閉塞部材21と構造体13の表面15とに密着することで、環状の内側に密閉空間37を形成する。構造体13は、表面15のヒビ17が、この密閉空間37に臨んで配置される。 A closing member 21 is provided in close contact with the sealing member 19 on the opposite side of the surface 15 with the sealing member 19 interposed therebetween. The closing member 21 has a peripheral edge portion 27 projecting outward from the sealing member 19 and covers the crack 17. Fixing members 23 are arranged at a plurality of locations in the circumferential direction on the peripheral edge portion 27 of the closing member 21. One end of the fixing member 23 is fixed to the structure 13. The other end side of the fixing member 23 penetrates the peripheral edge portion 27 and fixes the closing member 21 to the surface 15 of the structure 13. That is, the seal member 19 is sandwiched between the closing member 21 and the surface 15 of the structure 13. The seal member 19 is in close contact with the closing member 21 and the surface 15 of the structure 13 to form a closed space 37 inside the annular shape. In the structure 13, cracks 17 on the surface 15 are arranged so as to face the closed space 37.

ヒビ17は、密閉空間37に臨んで配置されるので、シール部材19の厚み分、閉塞部材21から離間して配置される。これにより、ヒビ17は、閉塞部材21により押圧されなくなる。すなわち、ヒビ17や、目地25を塞いだ既存の水密シール構造を損ねる(圧壊等する)ことがない。これに加え、新たな密閉空間37を形成し、ヒビ17や、目地25を塞いだ既存の水密シール構造にクラック等が発生した場合に生じる漏水を二重の水密シール構造より止水する作用を得ることができる。その結果、漏水をより効果的に抑制することができるようになる。 Since the crack 17 is arranged so as to face the closed space 37, the crack 17 is arranged so as to be separated from the closing member 21 by the thickness of the sealing member 19. As a result, the crack 17 is not pressed by the closing member 21. That is, the crack 17 and the existing watertight seal structure that closes the joint 25 are not damaged (crushed or the like). In addition to this, a new sealed space 37 is formed, and the double watertight seal structure stops water leakage that occurs when cracks or the like occur in the existing watertight seal structure that closes the crack 17 and the joint 25. Obtainable. As a result, water leakage can be suppressed more effectively.

また、この目地状部分の止水部材11では、閉塞部材21が、構造体13の表面15に沿う板状部材となる。表面15に沿うとは、平坦な表面15に対して平行となる場合、凹曲面である表面15に対して湾曲面となって沿う場合の双方を含む。いずれの場合においても、閉塞部材21は、板状部材となることにより、ヒビ17を覆う止水構造を構成した際に、構造体13の表面15からの突出距離を、ブロック状の部材で形成した場合に比べ小さくすることができる。その結果、水密シール構造を薄厚にできる。 Further, in the water blocking member 11 of the joint-shaped portion, the closing member 21 becomes a plate-shaped member along the surface 15 of the structure 13. The term "along the surface 15" includes both a case where the surface is parallel to the flat surface 15 and a case where the surface 15 is curved with respect to the surface 15 which is a concave curved surface. In any case, the closing member 21 is a plate-shaped member, so that when a water-stopping structure covering the crack 17 is formed, the protrusion distance from the surface 15 of the structure 13 is formed by the block-shaped member. It can be made smaller than when it is done. As a result, the watertight seal structure can be made thin.

また、この目地状部分の止水部材11では、シール部材19が、密着している状態よりも大きな所定の加圧力により、構造体13の表面15及び閉塞部材21の構造体対向面39に押圧される。このシール部材19に対する所定の加圧力は、閉塞部材21を固定部材23により構造体13へ締結固定することにより得られる。シール部材19は、この所定の圧力により、弾性限度の範囲で弾性変形する。従って、シール部材19は、変形されることによって生じた内部応力(弾性復元力)により、より確実に構造体13の表面15、及び閉塞部材21の構造体対向面39に水密に密着する。その結果、構造体13の表面15に生じている凹凸を吸収して高い止水性能を得ることができる。 Further, in the water blocking member 11 of the joint-shaped portion, the sealing member 19 presses against the surface 15 of the structure 13 and the structure facing surface 39 of the closing member 21 by a predetermined pressing force larger than the state of being in close contact with each other. Will be done. A predetermined pressing force on the seal member 19 is obtained by fastening and fixing the closing member 21 to the structure 13 by the fixing member 23. The seal member 19 is elastically deformed within the elastic limit range by this predetermined pressure. Therefore, the seal member 19 more reliably adheres to the surface 15 of the structure 13 and the structure facing surface 39 of the closing member 21 in a watertight manner due to the internal stress (elastic restoring force) generated by the deformation. As a result, it is possible to obtain high water stopping performance by absorbing the unevenness generated on the surface 15 of the structure 13.

また、本実施形態に係る目地状部分の止水構造では、上記した目地状部分の止水部材11の作用と同様に、ヒビ17や、目地25を塞いだ既存の水密シール構造を損ねる(圧壊等する)ことがない。これに加え、新たな密閉空間37を形成し、ヒビ17や、目地25を塞いだ既存の水密シール構造にヒビ17等が発生した場合に生じる漏水を二重の水密シール構造より止水する作用を得ることができる。その結果、漏水をより効果的に抑制することができるようになる。 Further, in the water-stopping structure of the joint-shaped portion according to the present embodiment, similarly to the action of the water-stopping member 11 of the joint-shaped portion described above, the crack 17 and the existing watertight seal structure that closes the joint 25 are damaged (crushed). Etc.) In addition to this, a new sealed space 37 is formed, and the action of stopping water leakage that occurs when cracks 17 or the existing watertight seal structure that closes the joint 25 occurs from the double watertight seal structure. Can be obtained. As a result, water leakage can be suppressed more effectively.

次に、上記した目地状部分の止水構造の変形例を説明する。 Next, a modified example of the water blocking structure of the joint-like portion described above will be described.

図3は目地25を覆って取り付けられた変形例1に係る目地状部分の止水構造を表す分解斜視図である。
変形例1に係る目地状部分の止水構造は、止水の対象となる目地状部分が、目地25となる。この点が上記した実施形態に係る目地状部分の止水構造と異なる。目地25は、縦目地でも横目地でもよい。例えば、図例では、コーキング35等により水密シールされた横目地に、水密シールされていない縦目地が直交する。変形例1に係る目地状部分の止水構造では、この縦方向の目地25が、目地状部分の止水部材41により覆われる。
FIG. 3 is an exploded perspective view showing a water blocking structure of the joint-like portion according to the first modification, which is attached so as to cover the joint 25.
In the water-stopping structure of the joint-shaped portion according to the first modification, the joint-shaped portion to be water-stopped is the joint 25. This point is different from the waterproof structure of the joint-like portion according to the above-described embodiment. The joint 25 may be a vertical joint or a horizontal joint. For example, in the illustrated example, the vertical joints that are not watertightly sealed are orthogonal to the horizontal joints that are watertightly sealed by caulking 35 or the like. In the water-stopping structure of the joint-shaped portion according to the first modification, the joint 25 in the vertical direction is covered with the water-stopping member 41 of the joint-shaped portion.

変形例1に係る目地状部分の止水部材41は、上記した実施形態と同様のものを用いることができる。但し、閉塞部材21及びシール部材19は、目地25の長さに合わせて長尺に形成される。また、固定部材23は、長尺の閉塞部材21に応じ数が増やされる。それ以外は、上記の目地状部分の止水部材11と同一である。 As the water blocking member 41 of the joint-like portion according to the first modification, the same one as in the above-described embodiment can be used. However, the closing member 21 and the sealing member 19 are formed to be long in accordance with the length of the joint 25. Further, the number of the fixing members 23 is increased according to the long closing member 21. Other than that, it is the same as the water blocking member 11 of the joint-like portion.

図4は図3に示した目地状部分の止水構造における平断面図である。
目地25は、接続された隣接する構造体13における接続面43の表面15に表れる。接続面43は、不図示の止水構造(パッキン等)で予め水密シールされていてもよい。また、目地25には、横目地と同様に、コーキング35が充填されていてもよい。この目地状部分の止水構造は、防火水槽や貯水槽などのコンクリート製水槽、コンクリート擁壁や斜面などの壁構造体等に用いることができる。
FIG. 4 is a plan sectional view of the water-stop structure of the joint-like portion shown in FIG.
The joint 25 appears on the surface 15 of the connecting surface 43 in the connected adjacent structure 13. The connection surface 43 may be watertightly sealed in advance with a waterproof structure (packing or the like) (not shown). Further, the joint 25 may be filled with caulking 35 in the same manner as the horizontal joint. This joint-like water-stopping structure can be used for concrete water tanks such as fire prevention water tanks and water storage tanks, and wall structures such as concrete retaining walls and slopes.

図5はT字状のヒビ17を覆う変形例2に係る目地状部分の止水構造を表す正面図である。
変形例2に係る目地状部分の止水構造は、止水の対象となる目地状部分が、T字状のヒビ17となる。この点が上記した実施形態に係る目地状部分の止水構造と異なる。変形例1に係る目地状部分の止水構造では、このT字状のヒビ17が、目地状部分の止水部材45により覆われる。
FIG. 5 is a front view showing the water blocking structure of the joint-shaped portion according to the modified example 2 covering the T-shaped crack 17.
In the water-stopping structure of the joint-shaped portion according to the second modification, the joint-shaped portion to be stopped is a T-shaped crack 17. This point is different from the waterproof structure of the joint-like portion according to the above-described embodiment. In the water-stopping structure of the joint-shaped portion according to the first modification, the T-shaped crack 17 is covered with the water-stopping member 45 of the joint-shaped portion.

変形例2に係る目地状部分の止水部材45は、閉塞部材47が、上記した実施形態の四角形と異なるT字形に形成されたものを用いる。また、シール部材49は、T字状のヒビ17を包囲できるT字形に形成されたものを用いる。或いは、T字形に形成された閉塞部材47の構造体対向面に環状のシール部材49をT字状に貼りつけ固定して用いてもよい。固定部材23は、T字形の閉塞部材47における周縁部27を所定間隔で固定できるように、その周長に応じ数が増やされる。それ以外は、上記の目地状部分の止水部材11と同一である。 As the water blocking member 45 of the joint-shaped portion according to the second modification, a closing member 47 having a T-shaped shape different from the quadrangle of the above-described embodiment is used. Further, as the seal member 49, a member formed in a T-shape capable of surrounding the T-shaped crack 17 is used. Alternatively, an annular seal member 49 may be attached and fixed in a T shape to the structure facing surface of the closing member 47 formed in a T shape. The number of the fixing members 23 is increased according to the peripheral length so that the peripheral edges 27 of the T-shaped closing member 47 can be fixed at predetermined intervals. Other than that, it is the same as the water blocking member 11 of the joint-like portion.

変形例2に係る目地状部分の止水構造によれば、直線状のヒビ以外の不定形のヒビ17に対しても、漏水を二重の水密シール構造より止水する作用を得ることができる。その結果、漏水をより効果的に抑制することができる。
なお、ヒビ17の形状に合わせて閉塞部材47を成型しなくても良く、ヒビ17を包囲するようにシール部材49が配置でき、それを覆うように閉塞部材47が不定形や四角形などで構成されていれば、同様の効果を得られる。
According to the water-stopping structure of the joint-like portion according to the second modification, it is possible to obtain the action of stopping water leakage from the double watertight seal structure even for irregular cracks 17 other than the linear cracks. .. As a result, water leakage can be suppressed more effectively.
It is not necessary to mold the closing member 47 according to the shape of the crack 17, and the sealing member 49 can be arranged so as to surround the crack 17, and the closing member 47 is formed of an irregular shape or a quadrangle so as to cover the sealing member 49. If so, the same effect can be obtained.

図6はシール部材19のバリエーションを(a)(b)(c)に表した模式図である。
シール部材19は、図6(a)に示すように、水膨張性材料からなる線状部材を、断面円形状の中実の水膨張部51で形成することができる。この場合、シール部材19を安価に製造できる。
FIG. 6 is a schematic view showing variations of the seal member 19 in (a), (b), and (c).
As shown in FIG. 6A, the seal member 19 can be formed of a linear member made of a water-expandable material by a solid water-expanding portion 51 having a circular cross section. In this case, the seal member 19 can be manufactured at low cost.

また、シール部材19は、図6(b)に示すように、水膨張性材料からなる水膨張部51と、水膨張性材料を含まない非水膨張部53と、から形成してもよい。 Further, as shown in FIG. 6B, the seal member 19 may be formed of a water-expandable portion 51 made of a water-expandable material and a non-water-expandable portion 53 containing no water-expandable material.

図6(b)に示すシール部材19は、線状部材における断面形状の外側を水膨張性材料で形成し、断面形状の内側を非水膨張部53で形成する。このような二重構造の線状部材で形成したシール部材19は、外側の水膨張性材料により止水性能が得られるとともに、内側の非水膨張部53により長手方向の膨張が規制される。これにより、シール部材19は、位置ずれを抑制して、周方向に膨張することが可能となり、構造体13の表面15及び閉塞部材21に確実に密着し、良好な止水性能を得ることができる。その結果、シール部材19の位置ずれを規制しながら、高い止水性能を得ることができる。 In the seal member 19 shown in FIG. 6B, the outside of the cross-sectional shape of the linear member is formed of a water-expandable material, and the inside of the cross-sectional shape is formed of the non-water-expandable portion 53. In the seal member 19 formed of such a double-structured linear member, water-stopping performance is obtained by the water-expandable material on the outside, and expansion in the longitudinal direction is regulated by the non-water-expandable portion 53 on the inside. As a result, the seal member 19 can be expanded in the circumferential direction by suppressing misalignment, and can be surely adhered to the surface 15 of the structure 13 and the closing member 21 to obtain good water stopping performance. it can. As a result, high water stopping performance can be obtained while restricting the displacement of the seal member 19.

図6(c)に示すように、線状部材は、図9(b)に示した非水膨張部53に中空部55を設けてもよい。 As shown in FIG. 6 (c), the linear member may be provided with a hollow portion 55 in the non-aqueous expansion portion 53 shown in FIG. 9 (b).

図7はシール部材19の他のバリエーションを(a)(b)(c)(d)(e)に表した模式図である。
また、図7(a)に示すシール部材19は、線状部材における断面形状の外側を水膨張部51で形成し、断面形状の内側を非水膨張部53で形成する。非水膨張部53には、中空部55を設ける。中空部55の内周面には、スプライン状の複数の凹凸部57を形成する。また、外側の水膨張部51には、線状部材の延在方向に沿う凸条59(リップ)を、線状部材の円周方向に複数等間隔で設けてもよい。
FIG. 7 is a schematic view showing other variations of the seal member 19 in (a), (b), (c), (d), and (e).
Further, in the seal member 19 shown in FIG. 7A, the outside of the cross-sectional shape of the linear member is formed by the water expansion portion 51, and the inside of the cross-sectional shape is formed by the non-water expansion portion 53. The non-water expansion portion 53 is provided with a hollow portion 55. A plurality of spline-shaped uneven portions 57 are formed on the inner peripheral surface of the hollow portion 55. Further, the outer water expansion portion 51 may be provided with a plurality of protrusions 59 (lips) along the extending direction of the linear member at equal intervals in the circumferential direction of the linear member.

図7(a)に示すシール部材19によれば、閉塞部材21と表面15とで挟まれ、線状部材が半径方向内側に圧縮された際、中空部55の凹凸部57が噛み合い、線状部材の捩れを抑制できる。また、凸条59が閉塞部材21や表面15に密着し、リップとして作用するので、複数段の止水構造を形成することができる。これにより、より高い止水性能を得ることができる。 According to the seal member 19 shown in FIG. 7A, when the sealing member 21 is sandwiched between the closing member 21 and the surface 15 and the linear member is compressed inward in the radial direction, the uneven portion 57 of the hollow portion 55 meshes with each other to form a linear shape. The twist of the member can be suppressed. Further, since the ridge 59 adheres to the closing member 21 and the surface 15 and acts as a lip, a multi-stage water blocking structure can be formed. As a result, higher water stopping performance can be obtained.

この他、シール部材19は、図7(b)(c)(d)(e)に示すように、線状部材の断面形状を四角形、台形、六角形、蒲鉾形とすることができる。これらの形状では、特に閉塞部材21との接着面を大きく確保することが容易となる。このため、特にシール部材19を閉塞部材に接着する場合に好適となる。 In addition, as shown in FIGS. 7 (b), (c), (d), and (e), the seal member 19 can have a quadrangular, trapezoidal, hexagonal, or semi-cylindrical cross-sectional shape. With these shapes, it becomes easy to secure a large adhesive surface with the closing member 21 in particular. Therefore, it is particularly suitable when the seal member 19 is adhered to the closing member.

図8は四角枠状の目地25を覆う変形例3に係る目地状部分の止水構造を表す分解斜視図である。
変形例3に係る目地状部分の止水構造は、止水の対象となる目地状部分が、四角形の目地25となる。つまり、目地25が閉じた形状となる。目地25は、四角形以外の多角形、例えば三角形、五角形、六角形、八角形や、円形、長円形、楕円形等であってもよい。さらに、目地25は、開いた形状、例えばC字形状であってもよい。変形例3に係る目地状部分の止水構造では、この四角形の目地25が、目地状部分の止水部材61により覆われる。
FIG. 8 is an exploded perspective view showing the water blocking structure of the joint-shaped portion according to the modified example 3 covering the square frame-shaped joint 25.
In the water-stopping structure of the joint-shaped portion according to the third modification, the joint-shaped portion to be stopped is a quadrangular joint 25. That is, the joint 25 has a closed shape. The joint 25 may be a polygon other than a quadrangle, for example, a triangle, a pentagon, a hexagon, an octagon, a circle, an oval, an ellipse, or the like. Further, the joint 25 may have an open shape, for example, a C shape. In the water-stopping structure of the joint-shaped portion according to the third modification, the square joint 25 is covered with the water-stopping member 61 of the joint-shaped portion.

変形例3に係る目地状部分の止水部材61は、内側シール部材63と、外側シール部材65と、を有する。本変形例では、四角形の目地25が、略正方形となる。内側シール部材63と外側シール部材65とは、同心状で構造体13の表面15に密着した際に、相互の間隙に目地25を配置する。つまり、構造体13の表面15に開放した四角形の目地25は、内側に内側シール部材63、外側に外側シール部材65が配置される。 The water blocking member 61 of the joint-like portion according to the third modification has an inner sealing member 63 and an outer sealing member 65. In this modification, the quadrangular joint 25 is a substantially square. When the inner seal member 63 and the outer seal member 65 are concentric and in close contact with the surface 15 of the structure 13, the joints 25 are arranged in the gaps between them. That is, in the quadrangular joint 25 opened to the surface 15 of the structure 13, the inner sealing member 63 is arranged inside and the outer sealing member 65 is arranged outside.

そして、構造体13の表面15に密着した内側シール部材63及び外側シール部材65には、外側シール部材65の外形より周縁部27の分大きい四角形の閉塞部材67が密着する。固定部材23は、内側シール部材63の内側、外側シール部材65の外側(すなわち、周縁部27)に設けられる。閉塞部材67は、周縁部27と表面15との間が、コーキング35によりさらに封止されてもよい。 Then, the inner seal member 63 and the outer seal member 65 which are in close contact with the surface 15 of the structure 13 are brought into close contact with the rectangular closing member 67 which is larger than the outer shape of the outer seal member 65 by the amount of the peripheral edge portion 27. The fixing member 23 is provided inside the inner seal member 63 and outside the outer seal member 65 (that is, the peripheral edge portion 27). The closing member 67 may be further sealed by caulking 35 between the peripheral edge portion 27 and the surface 15.

図9は図8に示した目地状部分の止水構造における左縦辺部近傍の平断面図である。
目地状部分の止水部材61は、内側シール部材63と外側シール部材65に、閉塞部材67が密着することにより、構造体13の表面15、内側シール部材63、外側シール部材65及び閉塞部材67に囲まれた環状の密閉空間37を形成する。四角形の目地25は、この環状の密閉空間37に臨んで配置される。
FIG. 9 is a plan sectional view of the vicinity of the left vertical side portion in the water blocking structure of the joint-like portion shown in FIG.
The water-stopping member 61 of the joint-like portion is such that the closing member 67 is in close contact with the inner sealing member 63 and the outer sealing member 65, so that the surface 15, the inner sealing member 63, the outer sealing member 65 and the closing member 67 of the structure 13 are brought into close contact with each other. An annular closed space 37 surrounded by is formed. The quadrangular joint 25 is arranged so as to face the annular closed space 37.

また、この目地状部分の止水部材61は、閉塞部材67が、内側シール部材63、外側シール部材65の挟持方向における一部分を受け入れる溝部69を有する。 Further, the water blocking member 61 of the joint-like portion has a groove portion 69 in which the closing member 67 receives a part of the inner sealing member 63 and the outer sealing member 65 in the sandwiching direction.

従って、それぞれの溝部69も四角形の環状に形成される。挟持方向における一部分とは、内側シール部材63及び外側シール部材65を形成している線状部材の断面形状における一部分である。つまり、溝部69に受け入れられたシール部材は、一部分を除く他部分が、閉塞部材67の構造体対向面39から構造体13の表面15に向かって突出する。この突出部分が、弾性変形可能な部分となる。弾性変形したシール部材は、弾性復元力が、溝部69や、構造体13の表面15への密着力となる。 Therefore, each groove 69 is also formed in a quadrangular ring shape. The part in the holding direction is a part in the cross-sectional shape of the linear member forming the inner seal member 63 and the outer seal member 65. That is, in the seal member received in the groove portion 69, other parts except a part project from the structure facing surface 39 of the closing member 67 toward the surface 15 of the structure 13. This protruding portion becomes a portion that can be elastically deformed. In the elastically deformed seal member, the elastic restoring force becomes the adhesion force to the groove portion 69 and the surface 15 of the structure 13.

内側シール部材63、外側シール部材65は、溝部69に接着等して固定しておくことが好ましい。この場合、内側シール部材63及び外側シール部材65は、目地状部分の止水部材11は、内側シール部材63、外側シール部材65を予め溝部69に固定しておくことにより、位置ずれを生じにくくすることができる。また、搬送や設置時の作業性を良好にできる。その結果、内側シール部材63、外側シール部材65が位置ずれすることによる止水性能の低下を防止できる。 It is preferable that the inner seal member 63 and the outer seal member 65 are fixed to the groove 69 by adhesion or the like. In this case, the inner seal member 63 and the outer seal member 65 are less likely to be misaligned by fixing the inner seal member 63 and the outer seal member 65 to the groove portion 69 in advance for the water stop member 11 in the joint portion. can do. In addition, workability during transportation and installation can be improved. As a result, it is possible to prevent deterioration of the water stopping performance due to the displacement of the inner seal member 63 and the outer seal member 65.

図10は構造体13の稜線部を覆う変形例4に係る目地状部分の止水構造を表す平断面図である。
変形例4に係る目地状部分の止水構造は、止水の対象となる目地状部分が、構造体13の稜線部分における目地25となる。目地25は、縦目地でも横目地でもよい。変形例4に係る目地状部分の止水構造では、この稜線部分の目地25が、目地状部分の止水部材71により覆われる。
FIG. 10 is a plan sectional view showing a water blocking structure of a joint-like portion according to the modified example 4 covering the ridgeline portion of the structure 13.
In the water-stopping structure of the joint-shaped portion according to the modified example 4, the joint-shaped portion to be stopped is the joint 25 at the ridgeline portion of the structure 13. The joint 25 may be a vertical joint or a horizontal joint. In the water-stopping structure of the joint-shaped portion according to the modified example 4, the joint 25 of the ridgeline portion is covered with the water-stopping member 71 of the joint-shaped portion.

変形例4に係る目地状部分の止水部材71は、閉塞部材73が山形に折り曲げられた屈曲プレートで形成される。また、固定部材23は、閉塞部材73の周縁部27に垂直な方向でそれぞれが構造体13に固定される。 The water blocking member 71 of the joint-shaped portion according to the fourth modification is formed by a bent plate in which the closing member 73 is bent into a chevron shape. Further, each of the fixing members 23 is fixed to the structure 13 in a direction perpendicular to the peripheral edge portion 27 of the closing member 73.

目地25は、接続された隣接する構造体13における接続面43の表面15に表れる。それぞれの構造体13の表面15は、出隅部となって交わる。構造体13の接続面43は、不図示の止水構造(パッキン等)で予め水密シールされていてもよい。また、目地25には、コーキング35が充填されていてもよい。この目地状部分の止水構造は、防火水槽や貯水槽などのコンクリート製水槽、コンクリート擁壁や斜面などの壁構造体等に用いることができる。 The joint 25 appears on the surface 15 of the connecting surface 43 in the connected adjacent structure 13. The surfaces 15 of the respective structures 13 intersect as protruding corners. The connection surface 43 of the structure 13 may be watertightly sealed in advance with a waterproof structure (packing or the like) (not shown). Further, the joint 25 may be filled with caulking 35. This joint-like water-stopping structure can be used for concrete water tanks such as fire prevention water tanks and water storage tanks, and wall structures such as concrete retaining walls and slopes.

目地状部分の止水部材71は、閉塞部材73が、出隅部の表面15に沿う形状に塑性変形可能な成形材料からなっていてもよい。 The water blocking member 71 of the joint portion may be made of a molding material in which the closing member 73 can be plastically deformed into a shape along the surface 15 of the protruding corner portion.

この場合、成形材料は、成形材料が取り付けられる面、すなわち、構造体13における出隅部の表面15などに合わせ、施工現場にて曲げ加工を行って使用する。
成形材料としては、例えば剛性の高い金属板が挙げられる。金属板の素材としては、例えば防錆性、防食性の高いSUSが挙げられる。曲げ加工は、例えばローラーを用いた冷間曲げ加工とすることができる。その結果、内側シール部材63及び外側シール部材65の変形量を全周囲で均等にでき、安定した止水性能を得ることができる。
In this case, the molding material is used after being bent at the construction site in accordance with the surface to which the molding material is attached, that is, the surface 15 of the protruding corner portion of the structure 13.
Examples of the molding material include a metal plate having high rigidity. Examples of the material of the metal plate include SUS having high rust and corrosion resistance. The bending process can be, for example, a cold bending process using a roller. As a result, the amount of deformation of the inner seal member 63 and the outer seal member 65 can be made uniform over the entire circumference, and stable water stopping performance can be obtained.

また、目地状部分の止水部材71は、閉塞部材73の少なくとも構造体対向面39が、出隅部の表面15に沿う形状に予め成形されていてもよい。 Further, in the water blocking member 71 of the joint-shaped portion, at least the structure facing surface 39 of the closing member 73 may be preformed into a shape along the surface 15 of the protruding corner portion.

この場合、内側シール部材63及び外側シール部材65を挟持する構造体13の表面15と、閉塞部材73の構造体対向面39との距離が、内側シール部材63及び外側シール部材65の全周囲においてほぼ同一となる。これにより、閉塞部材73と構造体13の表面15との間で内側シール部材63及び外側シール部材65を変形させる際の圧縮率を内側シール部材63及び外側シール部材65の全周囲でほぼ均等にすることができる。その結果、安定した止水性能を得ることができるとともに、予め表面15に沿う形状に成形されているので、現場での施工性を高めることができる。 In this case, the distance between the surface 15 of the structure 13 that sandwiches the inner seal member 63 and the outer seal member 65 and the structure facing surface 39 of the closing member 73 is the entire circumference of the inner seal member 63 and the outer seal member 65. It will be almost the same. As a result, the compressibility when deforming the inner seal member 63 and the outer seal member 65 between the closing member 73 and the surface 15 of the structure 13 is substantially equal around the entire circumference of the inner seal member 63 and the outer seal member 65. can do. As a result, stable water stopping performance can be obtained, and since the shape is formed in advance along the surface 15, workability at the site can be improved.

変形例5に係る目地状部分の止水部材81は、規制部材83を具備する。
FIG. 11 is an exploded perspective view showing the water-stopping member of the joint-shaped portion used for the water-stopping structure of the joint-shaped portion according to the modified example 5 provided with the regulating member together with the structure, and FIG. 12 is the joint-shaped portion shown in FIG. It is a plan sectional view of the state in which the water stop member of a part is assembled.
The water blocking member 81 of the joint-like portion according to the modified example 5 includes a regulating member 83.

この目地状部分の止水部材81では、閉塞部材85が平板よりなり、閉塞部材85と構造体13の表面15との間に規制部材83を介設する。
規制部材83は、例えば長円形の平板材に長円形の貫通部分をくり抜き形成した無端環状に形成されており、貫通部分の内径が、シール部材19を内装する径、或いはシール部材19の外径とほぼ同じになるよう設定され、また、厚みをシール部材19の直径よりも小さく設定し、且つこのシール部材19を圧縮した際、すなわち止水性能を得られる状態での圧縮方向の径よりも小さい値として形成され、図12に示すように断面矩形状で、この断面形状が連続する環状の部材とされる。
In the water blocking member 81 of the joint-like portion, the closing member 85 is made of a flat plate, and the regulating member 83 is interposed between the closing member 85 and the surface 15 of the structure 13.
The regulating member 83 is formed, for example, in an endless annular shape formed by hollowing out an oval penetrating portion in an oval flat plate member, and the inner diameter of the penetrating portion is the diameter inside the seal member 19 or the outer diameter of the seal member 19. The thickness is set to be smaller than the diameter of the seal member 19, and the diameter of the seal member 19 is larger than the diameter in the compression direction when the seal member 19 is compressed, that is, in a state where water stopping performance can be obtained. It is formed as a small value, has a rectangular cross section as shown in FIG. 12, and is an annular member having a continuous cross section.

この目地状部分の止水部材81によれば、規制部材83がシール部材19の外周にシール部材19を取り囲むように位置し、閉塞部材105と構造体13の表面15との間でシール部材19とともに挟持状態となる。すなわち、シール部材19は、環状の規制部材83の内側に位置する。 According to the water blocking member 81 of the joint-like portion, the regulating member 83 is located on the outer periphery of the sealing member 19 so as to surround the sealing member 19, and the sealing member 19 is located between the closing member 105 and the surface 15 of the structure 13. At the same time, it becomes a pinched state. That is, the seal member 19 is located inside the annular regulation member 83.

この状態でシール部材19は閉塞部材85と構造体13の表面15とに密着し、漏水を抑制することとなり、この漏水によってシール部材19が膨張した際には、径の外方への膨張変形が起こっても、規制部材83により閉塞部材85と表面15との間を面に沿って膨張変形してしまうことを抑え、すなわち、閉塞部材85の面と構造体表面15と規制部材83の内径側とで三方向をシール部材19が囲まれていることとなり、規制部材83の内側、つまり密閉空間37内方向での膨張となって三方向の各面に対して確実に密着して目地状部分を包囲してシール性を向上でき、漏水をより効果的に抑制することができることとなる。 In this state, the seal member 19 comes into close contact with the closing member 85 and the surface 15 of the structure 13 to suppress water leakage, and when the seal member 19 expands due to this water leakage, the seal member 19 expands and deforms outward in diameter. Is prevented from expanding and deforming between the closing member 85 and the surface 15 along the surface by the regulating member 83, that is, the surface of the closing member 85, the structure surface 15, and the inner diameter of the regulating member 83. The seal member 19 is surrounded by the side in three directions, and the seal member 19 expands inside the regulation member 83, that is, in the closed space 37, and is surely adhered to each surface in the three directions to form a joint. The sealing property can be improved by surrounding the portion, and water leakage can be suppressed more effectively.

In each case, the seal member 19 surrounds the cracks 17 and the joints 25, which are joint-like portions, and the seal member 19 is inside the regulation member 83 and is covered with the closing member 85. Further, as shown in FIGS. 12 (a) and 12 (b), the rust preventive effect of the metal nut 45 can be obtained by providing the resin cap 32 that covers the nut 31.

この目地状部分の止水部材91によれば、上記変形例5と同様に、シール部材19は閉塞部材95と構造体13の表面15とに密着し、漏水を抑制することとなり、この漏水によってシール部材19が膨張した際には、径の外方への膨張変形が起こっても、規制部93により閉塞部材95と表面15との間を面に沿って膨張変形してしまうことを抑え、すなわち、閉塞部材95の面と構造体表面15と規制部93の内径側とで三方向をシール部材19が囲まれていることとなり、規制部93の内側、つまり密閉空間37内(図12参照)での膨張となって三方向の各面に対して確実に密着し、ヒビ17を包囲してシール性を向上でき、漏水をより効果的に抑制することができることとなる。 According to the water blocking member 91 of the joint-like portion, the sealing member 19 is in close contact with the closing member 95 and the surface 15 of the structure 13 to suppress water leakage, as in the modified example 5, and this water leakage causes the water leakage. When the seal member 19 expands, even if the seal member 19 expands and deforms outward in diameter, the regulating portion 93 suppresses the expansion and deformation between the closing member 95 and the surface 15 along the surface. That is, the sealing member 19 is surrounded in three directions by the surface of the closing member 95, the surface of the structure 15, and the inner diameter side of the regulating portion 93, and the inside of the regulating portion 93, that is, the inside of the closed space 37 (see FIG. 12). ), It is surely adhered to each surface in the three directions, surrounds the crack 17 to improve the sealing property, and water leakage can be suppressed more effectively.

It is possible to fix the seal member 19 to the closing member plate surface 39 inside the regulation portion 93 with an adhesive or the like. By fixing the seal member 19 in advance in this way, the handling becomes easier, and the work can be simplified without the seal member 19 falling off when the seal member 19 is attached to the structure 13.

Further, an annular groove portion 127 for receiving a part of the annular seal member 19 in the sandwiching direction is formed on the structure facing surface of the closing member 123 inside the regulating portion 125. The inner surface of the regulation portion 125 located on the outer periphery of the groove portion 127 and the inner surface of the groove portion 127 are continuously formed. As shown in FIG. 16B, in order to form the groove portion 127, the thickness of the closing member 123 inside the groove portion 127 is set to be slightly thicker, and the depth of the groove portion 127 is a part of the seal member 19. Is accepted, and the regulation portion 125 is formed so as to surround the groove portion 127. The inner diameter of the regulating portion 125 is set to be larger than or equivalent to the outer diameter of the sealing member 19, the sealing member 19 is housed inside the regulating portion 125, and the height of the regulating portion 125 from the groove portion 127. The thickness of the seal member 19 is set to be smaller than the thickness of the seal member 19 in the compressed state so as not to prevent the seal member 19 from adhering to the structure surface 15.

この目地状部分の止水部材121によれば、上記変形例8と同様に、シール部材19は閉塞部材123と構造体13の表面15とに密着し、漏水を抑制することとなり、この漏水によってシール部材19が径の外方への膨張変形が起こっても、閉塞部材123の溝部127と構造体表面15と規制部125の内径側とで三方向をシール部材19が囲まれていることとなり、規制部125の内側、つまり密閉空間37内(図10参照)での膨張となって三方向の各面に対して確実に密着しヒビ17を包囲してシール性を向上でき、漏水をより効果的に抑制することができることとなる。 According to the water blocking member 121 of the joint-like portion, the sealing member 19 is in close contact with the closing member 123 and the surface 15 of the structure 13 to suppress water leakage, as in the modified example 8, and this water leakage causes the water leakage. Even if the seal member 19 expands and deforms outward in diameter, the seal member 19 is surrounded in three directions by the groove portion 127 of the closing member 123, the structure surface 15, and the inner diameter side of the regulation portion 125. , The inside of the regulation part 125, that is, the inside of the closed space 37 (see FIG. 10) expands and surely adheres to each surface in three directions to surround the crack 17 to improve the sealing property and prevent water leakage. It can be effectively suppressed.

また、この目地状部分の止水部材121によれば、閉塞部材123と規制部125とが一体構造であることで、取り扱いが容易となり、さらには、規制部125の内側において、溝部127内に予めシール部材19を取り付けておくことが可能となる。シール部材19は、溝部127に接着等して固定することとしてもよい。このように予め固定させておくことで、さらに取り扱いが容易となるもので、構造体13への装着時にシール部材19の位置ズレの防止や脱落させてしまうことなく、作業の煩雑さを低減させることが可能となる。また、シール部材19の位置ズレを防ぐことで止水性能の低下を防止できる。また、閉塞部材123の周縁部129を厚みのある構成としたことで、剛性が向上し、固定部材23の貫通状態が増し、安定して支持される。 Further, according to the water blocking member 121 of the joint-like portion, since the closing member 123 and the regulating portion 125 have an integrated structure, it is easy to handle, and further, inside the regulating portion 125, inside the groove portion 127. The seal member 19 can be attached in advance. The seal member 19 may be fixed to the groove portion 127 by adhesion or the like. By fixing in advance in this way, it becomes easier to handle, and the complexity of the work is reduced without preventing the seal member 19 from being displaced or falling off when it is attached to the structure 13. It becomes possible. Further, by preventing the seal member 19 from being displaced, it is possible to prevent the water stopping performance from being deteriorated. Further, since the peripheral edge portion 129 of the closing member 123 has a thick structure, the rigidity is improved, the penetration state of the fixing member 23 is increased, and the fixing member 23 is stably supported.

なお、上記した変形例6〜9では、構造体13にヒビ17が生じている場合について図示し説明したが、上述した変形例1のような目地25に対しても同様に構成でき、上記同様の効果、すなわち、環状のシール部材19が目地25を包囲して漏水を抑制することができる効果を得られる。 In the above-mentioned modified examples 6 to 9, the case where the structure 13 has cracks 17 has been illustrated and described, but the joint 25 as in the above-mentioned modified example 1 can be similarly configured, and the same as above. That is, the effect that the annular sealing member 19 can surround the joint 25 and suppress water leakage can be obtained.

図17は規制部材を構造体表面に構成した変形例10を(a)に変形例11を(b)に示した平断面図である。
上述した変形例6〜9においては、規制部材(93,107,115,125)を閉塞部材(95,103,113,123)と一体に構成した例として示したが、規制部材を構造体13の表面15に構成させ、すなわち構造体13と一体構造としてもよい。
FIG. 17 is a plan sectional view showing a modified example 10 in which a regulating member is formed on the surface of a structure in (a) and a modified example 11 in (b).
In the above-described modified examples 6 to 9, the restricting member (93, 107, 115, 125) is shown as an example of being integrally formed with the closing member (95, 103, 113, 123), but the regulating member is the structure 13. It may be formed on the surface 15 of the above, that is, it may be integrated with the structure 13.

変形例10に係る目地状部分の止水部材131では、図17(a)に示すように、構造体13の表面15に開口する目地25の周囲を囲むように、規制部材としての規制部133が畦状に形成される。規制部133は、無端環状或いは枠状,額縁状に形成されており、目地25の周囲において、目地25より外側に位置して構造体表面15から突出するように設けられる。目地25の周囲は、シール部材19が密着する面とされ、シール部材19の内径が目地25の長さよりも十分に大きく設定され、目地25を囲むようにシール部材19が配置され、シール部材19の外径よりも大きい内径となるように規制部133が形成され、規制部133の内側にシール部材19が収容状態となる。規制部133の高さ(厚み)は、シール部材19が圧縮された状態での厚みよりも小さく設定される。また、この変形例10においては、閉塞部材135は平板状に形成される。 In the joint-shaped portion of the water-stopping member 131 according to the modified example 10, as shown in FIG. 17A, the regulating portion 133 as a regulating member surrounds the joint 25 that opens to the surface 15 of the structure 13. Is formed in a ridge shape. The regulating portion 133 is formed in an endless ring shape, a frame shape, or a frame shape, and is provided around the joint 25 so as to be located outside the joint 25 and project from the structure surface 15. The periphery of the joint 25 is a surface to which the seal member 19 is in close contact, the inner diameter of the seal member 19 is set sufficiently larger than the length of the joint 25, the seal member 19 is arranged so as to surround the joint 25, and the seal member 19 is arranged. The regulating portion 133 is formed so that the inner diameter is larger than the outer diameter of the regulating portion 133, and the seal member 19 is housed inside the regulating portion 133. The height (thickness) of the regulating portion 133 is set to be smaller than the thickness of the sealing member 19 in the compressed state. Further, in the modified example 10, the closing member 135 is formed in a flat plate shape.

この目地状部分の止水部材131によれば、上記変形例6と同様に、シール部材19は閉塞部材135と構造体13の表面15とに密着し、漏水を抑制することとなり、この漏水によってシール部材19が膨張した際には、径の外方への膨張変形が起こっても、規制部133により閉塞部材135と表面15との間を面に沿って膨張変形してしまうことを抑え、すなわち、閉塞部材135の面と構造体表面15と規制部133の内径側とで三方向をシール部材19が囲まれていることとなり、規制部133の内側、つまり密閉空間37内(図12参照)での膨張となって三方向の各面に対して確実に密着し、目地25を包囲してシール性を向上でき、漏水をより効果的に抑制することができることとなる。 According to the water blocking member 131 of the joint-like portion, the sealing member 19 is in close contact with the closing member 135 and the surface 15 of the structure 13 to suppress water leakage, as in the modified example 6, and this water leakage causes the water leakage. When the seal member 19 expands, even if the seal member 19 expands and deforms outward in diameter, the restricting portion 133 suppresses the expansion and deformation between the closing member 135 and the surface 15 along the surface. That is, the seal member 19 is surrounded in three directions by the surface of the closing member 135, the surface of the structure 15, and the inner diameter side of the regulating portion 133, and the inside of the regulating portion 133, that is, the inside of the closed space 37 (see FIG. 12). ), It is surely adhered to each surface in the three directions, surrounds the joint 25 to improve the sealing property, and water leakage can be suppressed more effectively.

また、この目地状部分の止水部材141によれば、構造体13と規制部133とが一体構造であることで、規制部133の内側に予めシール部材19を取り付けておくこと、例えば規制部133の内側における構造体表面15に接着剤などでシール部材19を固定することが可能となる。このように予め固定させておくことで、シール部材19の脱落を防ぎ、作業性を低下させることがなく、また、シール部材19の位置ズレを防ぐことが可能となる。 Further, according to the water blocking member 141 of the joint-like portion, since the structure 13 and the regulating portion 133 have an integrated structure, the sealing member 19 is attached in advance to the inside of the regulating portion 133, for example, the regulating portion. The seal member 19 can be fixed to the structure surface 15 inside the 133 with an adhesive or the like. By fixing the seal member 19 in advance in this way, it is possible to prevent the seal member 19 from falling off, not to reduce workability, and to prevent the seal member 19 from being displaced.

変形例11に係る目地状部分の止水部材141では、図17(b)に示すように、変形例10と同様、構造体13の表面15に開口する目地25の周囲を囲むように、規制部材としての規制部143が形成される。この変形例11においては、上述した変形例7と同様に、構造体表面15の目地25周囲に凹部145が形成され、この凹部145の内周面を規制部143としている。 As shown in FIG. 17B, the water-stopping member 141 of the joint-like portion according to the modified example 11 is regulated so as to surround the periphery of the joint 25 opened on the surface 15 of the structure 13 as in the modified example 10. The regulation portion 143 as a member is formed. In the modified example 11, a recess 145 is formed around the joint 25 of the structure surface 15 and the inner peripheral surface of the recess 145 is used as the regulating portion 143, as in the modified example 7 described above.

凹部145は、目地25の周囲に形成され、シール部材19の挟持方向における一部分を受け入れる深さで形成される。この凹部145内にてシール部材19が密着する面とされ、目地25を囲むようにシール部材19が配置され、シール部材19の外径よりも大きい内径となるように規制部143が配置され、シール部材19が収容状態となる。凹部145の深さである規制部143の高さは、シール部材19が圧縮された状態での厚みよりも小さく設定される。また、この変形例11においては、閉塞部材147は平板状に形成される。 The recess 145 is formed around the joint 25 and has a depth that accepts a part of the seal member 19 in the sandwiching direction. The seal member 19 is provided as a surface to be brought into close contact with the seal member 19 in the recess 145, the seal member 19 is arranged so as to surround the joint 25, and the regulation portion 143 is arranged so that the inner diameter is larger than the outer diameter of the seal member 19. The seal member 19 is in the housed state. The height of the regulating portion 143, which is the depth of the recess 145, is set to be smaller than the thickness of the sealing member 19 in the compressed state. Further, in the modified example 11, the closing member 147 is formed in a flat plate shape.

この目地状部分の止水部材141によれば、シール部材19は閉塞部材147と構造体13とに密着し、漏水を抑制することとなり、この漏水によってシール部材19が径の外方への膨張変形が起こっても、閉塞部材147の面と構造体表面15の凹部145と規制部143の内径側とで三方向をシール部材19が囲まれていることとなり、規制部143の内側、つまり密閉空間37内(図12参照)での膨張となって三方向の各面に対して確実に密着し目地25を包囲してシール性を向上でき、漏水をより効果的に抑制することができることとなる。 According to the water blocking member 141 of the joint-like portion, the sealing member 19 comes into close contact with the closing member 147 and the structure 13 to suppress water leakage, and the water leakage causes the sealing member 19 to expand outward in diameter. Even if deformation occurs, the sealing member 19 is surrounded in three directions by the surface of the closing member 147, the recess 145 of the structure surface 15, and the inner diameter side of the regulating portion 143, and the inside of the regulating portion 143, that is, sealed. It expands in the space 37 (see FIG. 12) and surely adheres to each surface in three directions to surround the joint 25 to improve the sealing property and to suppress water leakage more effectively. Become.

また、この目地状部分の止水部材141によれば、構造体13と規制部143とが一体構造であることで、規制部143の内側に予めシール部材19を取り付けておくこと、例えば接着剤などでシール部材19を固定することが可能となる。このように予め固定させておくことで、シール部材19の脱落を防ぎ、作業性を低下させることがなく、また、シール部材19の位置ズレを防ぐことが可能となる。 Further, according to the water blocking member 141 of the joint-like portion, since the structure 13 and the regulating portion 143 have an integral structure, the sealing member 19 is attached in advance to the inside of the regulating portion 143, for example, an adhesive. The seal member 19 can be fixed by such means. By fixing the seal member 19 in advance in this way, it is possible to prevent the seal member 19 from falling off, not to reduce workability, and to prevent the seal member 19 from being displaced.

このように構成された変形例10と変形例11においては、構造体13の表面15に規制部133,143が形成されることで、閉塞部材135,147は平板で構成でき、部材としての加工が少なく、目地状部分の止水部材131,141として簡素な構成とすることが可能となる。 In the modified examples 10 and 11 configured in this way, the closing members 135 and 147 can be formed of flat plates by forming the regulating portions 133 and 143 on the surface 15 of the structure 13, and are processed as members. It is possible to have a simple structure as the water blocking members 131 and 141 of the joint-like portion.

なお、上述した変形例5〜11における規制部材(規制部)は、それぞれ環状に形成されシール部材19を囲むように連続した構成とされた例を述べたが、この規制部材(規制部)は、シール部材19を囲み、周方向に断続して形成される構成としてもよい。すなわち、規制部材或いは規制部の形状として、閉塞部材と構造体の表面との間において駒状に断続して配置される、或いは断続して形成されるような構成としてもよく、シール部材19の外方向への膨張を規制するように、閉塞部材と構造体表面との間隙部分に設けられることとする。このような構成であっても、上記同様に、シール部材19が膨張変形した際に、径の外方への変形を抑え、漏水を抑制することができる。 In addition, although the example in which the regulation member (regulation part) in the above-described modified examples 5 to 11 is formed in an annular shape and has a continuous structure so as to surround the seal member 19, the regulation member (regulation part) is described. , The seal member 19 may be surrounded and formed intermittently in the circumferential direction. That is, the shape of the regulating member or the regulating portion may be such that it is intermittently arranged in a piece shape between the closing member and the surface of the structure, or is formed intermittently. It is provided in the gap between the closing member and the surface of the structure so as to regulate the outward expansion. Even with such a configuration, when the seal member 19 expands and deforms, the deformation of the seal member 19 to the outside can be suppressed and water leakage can be suppressed.

図18は規制部材を構造体表面に構成した変形例12を(a)に変形例13を(b)に示した平断面図である。
構造体13の表面15に経年劣化などで生じたヒビ17に対して止水構造を構成させる例として、ヒビ17の周囲をはつり、上述した変形例11と同様な凹部を形成して、この凹部の内周面を規制部として構成させて得ることとしても良い。
FIG. 18 is a plan sectional view showing a modified example 12 in which a regulating member is formed on the surface of a structure in (a) and a modified example 13 in (b).
As an example of forming a water-stop structure on the surface 15 of the structure 13 against cracks 17 generated due to aged deterioration or the like, the periphery of the cracks 17 is slid to form a recess similar to the above-described modified example 11, and the recess is formed. It may be obtained by configuring the inner peripheral surface of the above as a regulation part.

変形例12に係る目地状部分の止水部材151は、図18(a)に示すように、ヒビ17の生じた構造体13に、ヒビ17の周囲をはつり凹部153を形成し、この凹部153の内周面を規制部155とする。この規制部155の内側にシール部材19を嵌め込み、さらに平板状の閉塞部材157にて覆い固定部材23にて固定することで、シール部材19を圧縮して密着させる。なお、図18(a)に示すように、凹部153の周囲に、閉塞部材157が嵌入できる段部159を形成し、閉塞部材157の表面と構造体表面15とを面一とするよう構成してもよく、このような構成とすることで止水構造を目立たなくすることが可能となる。 As shown in FIG. 18A, the water-stopping member 151 of the joint-like portion according to the modified example 12 forms a chipping recess 153 around the crack 17 in the structure 13 in which the crack 17 is generated, and the recess 153 is formed. The inner peripheral surface of the above is designated as the regulation unit 155. The seal member 19 is fitted inside the regulation portion 155, and further covered with a flat plate-shaped closing member 157 and fixed with the fixing member 23 to compress and bring the seal member 19 into close contact. As shown in FIG. 18A, a step portion 159 into which the closing member 157 can be fitted is formed around the recess 153 so that the surface of the closing member 157 and the surface of the structure 15 are flush with each other. However, such a configuration makes it possible to make the waterproof structure inconspicuous.

また、変形例13に係る目地状部分の止水部材161は、図18(b)に示すように、閉塞部材163を上述した変形例7のように厚みのある板材で構成して、構造体13に対向する面に円形の凹部165を形成して、この凹部165の内周面部分を規制部材としての規制部167として構成している。そして、ヒビ17の生じた構造体13には、ヒビ17の周囲をはつり嵌入凹部169が切削形成される。嵌入凹部169は、閉塞部材163を収容できる大きさとされる。 Further, as shown in FIG. 18B, the water blocking member 161 of the joint-like portion according to the modified example 13 is a structure in which the closing member 163 is made of a thick plate material as in the above-mentioned modified example 7. A circular recess 165 is formed on the surface facing the portion 13, and the inner peripheral surface portion of the recess 165 is configured as a regulation portion 167 as a regulation member. Then, in the structure 13 in which the crack 17 is generated, a fitting recess 169 is formed by cutting around the crack 17. The fitting recess 169 is sized to accommodate the closing member 163.

この変形例12,13に係る目地状部分の止水部材151,161によれば、構造体13に生じたヒビ17に対してシール部材19にて止水する作用を得られるもので、構造体13の補修として、ヒビ17の周囲を切削し凹部を形成させることが可能な場合に有効である。また、規制部155,167によってシール部材19の脱落などを防ぐことが可能となり、作業性が良好となる。 According to the joint-shaped water blocking members 151 and 161 according to the modified examples 12 and 13, the sealing member 19 can stop water from the cracks 17 generated in the structure 13. As a repair of 13, it is effective when it is possible to cut around the crack 17 to form a recess. Further, the regulating portions 155 and 167 make it possible to prevent the seal member 19 from falling off, and the workability is improved.
