Description
【０００１】[0001]
本考案は、山留め壁に適用されるコンクリート型枠保持装置に係り、特に水漏 れを完全に防止することができるコンクリート型枠保持装置に関する。 The present invention relates to a concrete formwork holding device applied to a mountain retaining wall, and more particularly to a concrete formwork holding device capable of completely preventing water leakage.
【０００２】[0002]
従来、山留め壁に適用されるコンクリート型枠保持装置としては、図１３に示 すように、山留め壁を構成する例えばＨ形鋼１に、溶接座２ａを有する雄ねじ部 材２を溶接するとともに、両端内面に雌ねじ部を有する筒状の矢板控金具３の一 端を螺装し、一方矢板控金具３の他端には、セパレータ４の一端を螺装し、セパ レータ４の他端に取付けられたピーコン５で型枠６を内側から支持するようにし たものが知られている。 Conventionally, as a concrete formwork holding device applied to a mountain retaining wall, as shown in FIG. 13, for example, an H-shaped steel 1 forming the mountain retaining wall is welded with a male screw member 2 having a welding seat 2a, and One end of the tubular sheet metal fitting 3 having female threads on the inner surfaces of both ends is screwed, while one end of the separator 4 is screwed to the other end of the sheet metal fitting 3 and attached to the other end of the separator 4. It is known that the formwork 5 is used to support the formwork 6 from the inside.
【０００３】 ところで、この種のコンクリート型枠保持装置を用いて型枠６を保持する際に は、Ｈ形鋼１から型枠６までの距離が場所によって異なるため、セパレータ４の 矢板控金具３への螺入量を調節してこれを吸収し、その後、セパレータ４に螺装 されている板ナット７を矢板控金具３に締付けて、セパレータ４と矢板控金具３ とを固定している。また、セパレータ４等を伝わってコンクリート壁の前面に水 が漏れ出すのを防止するため、ドーナツ円板状をなす例えばゴム製の止水板８を セパレータ４に装着するようにしている。By the way, when holding the formwork 6 using this type of concrete formwork holding device, since the distance from the H-shaped steel 1 to the formwork 6 differs depending on the place, the sheet metal fitting 3 of the separator 4 is used. The amount of screwing into the sheet metal is adjusted and absorbed, and then the plate nut 7 screwed to the separator 4 is tightened to the sheet metal fitting 3 to fix the separator 4 and the sheet metal fitting 3. Further, in order to prevent water from leaking to the front surface of the concrete wall through the separator 4, etc., a water stop plate 8 made of, for example, a rubber in the form of a donut disk is attached to the separator 4.
【０００４】[0004]
前記従来のコンクリート型枠保持装置においては、セパレータ４と矢板控金具 ３との固定を、軸方向寸法の短い板ナット７で行なっているため固定力が弱く、 ピーコン５に締付金具等を装着する際に板ナット７が緩んでしまい、安定した型 枠保持力が得られないという問題がある。 In the conventional concrete formwork holding device, since the separator 4 and the sheet pile holding fixture 3 are fixed by the plate nut 7 having a short axial dimension, the fixing force is weak, and the fastening fixture or the like is attached to the peecon 5. When doing so, there is a problem that the plate nut 7 becomes loose and stable mold holding force cannot be obtained.
【０００５】 また、水漏れを止水板８で防止するようにしているが、セパレータ４には、ア ジャスト寸法を大きくとる必要から長い雄ねじ部が設けられているため、止水効 果を上げるために止水板８を矢板控金具３に近付けようとすると、止水板８を雄 ねじ部に装着せざるを得ず、この場合には、雄ねじ部の谷部と止水板８との間に 隙間が生じるので、この隙間を通って水漏れするおそれがある。Further, although water leakage is prevented by the water stop plate 8, since the separator 4 is provided with a long male screw portion in order to have a large adjustment size, the water stop effect is improved. Therefore, when trying to bring the water stop plate 8 closer to the sheet metal fitting 3, the water stop plate 8 must be attached to the male screw portion, and in this case, the trough portion of the male screw part and the water stop plate 8 are connected. Since there is a gap between them, water may leak through this gap.
【０００６】 これを避けるために、止水板８を雄ねじ部を外して装着しようとすると、止水 板８の位置がピーコン５に極端に近い位置となってしまい、この場合には止水効 果がほとんど期待できないという問題がある。In order to avoid this, if the male screw portion of the water blocking plate 8 is removed and the water blocking plate 8 is mounted, the position of the water blocking plate 8 becomes extremely close to the pecon 5, and in this case, the water blocking effect is obtained. There is a problem that the fruit can hardly be expected.
【０００７】 本考案は、かかる現況に鑑みなされたもので、セパレータと矢板控金具とを大 きな力で固定することができ、しかも水漏れを完全に防止することができるコン クリート型枠保持装置を提供することを目的とする。The present invention has been made in view of the current situation, and it is possible to fix the separator and the sheet pile holding metal member with a large force, and further, to prevent the water leakage completely, the concrete form holding The purpose is to provide a device.

【００３６】 この接着剤カプセル１４は、図２に示すように、合成樹脂フィルムや金属泊等 で形成される脆弱なカプセル１４ａ内に、アクリル系，酢酸ビニル系あるいはゴ ム系樹脂等から接着剤１４ｂを封入して構成されており、ナット部材１２を矢板 控金具３に締付けて接着剤カプセル１４を両側から押圧することにより、図３に 示すように、カプセル１４ａが破れて接着剤１４ｂが流出し、流出した接着剤１ ４ｂがねじ部に流入して、ねじ部が完全にシールされるようになっている。As shown in FIG. 2, the adhesive capsule 14 is made of an acrylic, vinyl acetate or rubber resin in an fragile capsule 14a formed of a synthetic resin film or metal foil. 14b is enclosed, and by tightening the nut member 12 to the sheet metal fitting 3 and pressing the adhesive capsule 14 from both sides, as shown in FIG. 3, the capsule 14a is broken and the adhesive 14b flows out. Then, the adhesive 14b that has flowed out flows into the threaded portion, and the threaded portion is completely sealed.
【００３７】 次に、本実施例の作用について説明する。 型枠６の保持に際しては、まずＨ形鋼１に雄ねじ部材２の溶接座２ａを溶接し 、この雄ねじ部材２に、止水部材１１を装着した後に矢板控金具３の一端を螺装 する。これにより、溶接座２ａと矢板控金具３との間が完全にシールされ、山留 め壁側からの水が矢板控金具３の内部に浸入するのを完全に防止することができ るとともに、止水部材１１がスプリングワッシャとして機能し、矢板控金具３の 緩みを防止することもできる。Next, the operation of this embodiment will be described. When holding the mold 6, first, the welding seat 2a of the male screw member 2 is welded to the H-shaped steel 1, the water stop member 11 is attached to the male screw member 2, and then one end of the sheet metal fitting 3 is screwed. As a result, the space between the welding seat 2a and the sheet metal fitting 3 is completely sealed, and it is possible to completely prevent water from the mountain retaining wall side from entering the inside of the sheet metal fitting 3. The water stop member 11 functions as a spring washer, and can prevent the sheet metal fitting 3 from loosening.
【００３８】 次いで、矢板控金具３の他端に、セパレータ４の長さ調節用雄ねじ部４ａをね じ込むとともに、セパレータ４の連結用雄ねじ部４ｂにピーコン５を螺装連結す る。そして、長さ調節用雄ねじ部４ａの矢板控金具３へのねじ込み量を調節して 、ピーコン５の位置決めを行なう。Next, the length adjusting male screw part 4 a of the separator 4 is screwed into the other end of the sheet pile metal fitting 3, and the pecon 5 is screwed and connected to the connecting male screw part 4 b of the separator 4. Then, the amount of screwing the length adjusting male screw portion 4a into the sheet metal fitting 3 is adjusted to position the computer 5.
【００３９】 ピーコン５の位置決め後、ナット部材１２を矢板控金具３に締付け、セパレー タ４と矢板控金具３とを固定する。この際、ナット部材１２は軸方向に長い六角 ナット部１２ａを有していて全体の軸方向長さが長いので、大きな締付力が得ら れ、ナット部材１２の緩みを防止できるとともに、接着剤１４ｂの固化後は、ナ ット部材１２の緩みを完全に防止することができる。After the positioning of the PC 5, the nut member 12 is tightened to the sheet metal fitting 3 to fix the separator 4 and the sheet metal fitting 3. At this time, since the nut member 12 has a hexagonal nut portion 12a that is long in the axial direction and the entire axial length is long, a large tightening force can be obtained, and the nut member 12 can be prevented from loosening and bonded. After the agent 14b is solidified, the nut member 12 can be completely prevented from loosening.
【００４０】 すなわち、ナット部材１２を矢板控金具３に締付けると、図２に示すように、 接着剤カプセル１４がナット部材１２の鍔部１２ｂと矢板控金具３の先端との間 で両側から押圧されることになる。このため、図３に示すように、カプセル１４ ａが破れ接着剤１４ｂが流出する。この際、止水部材１３の孔１３ｂは、矢板控 金具３の先端外径とほぼ同一に設定されているので、ナット部材１２の締付けに より、矢板控金具３の先端が孔１３ｂに挿入され、しかも矢板控金具３の外面は 、図中右方に向かって次第に拡径する截頭円錐状をなしているので、ナット部材 １２の締付けにより孔１３ｂの内周面に完全に密着する。このため、カプセル１ ４ａから流出した接着剤１４ｂは、鍔部１２ｂ，止水部材１３および矢板控金具 ３で囲まれた空間内に閉じ込められ、この空間は、ナット部材１２の締付けによ り次第に縮小していくので、接着剤１４ｂは、そのほぼ全量が、ナット部材１２ とセパレータ４との間のねじ部および矢板控金具３とセパレータ４との間のねじ 部に流入し、ここで固化することになる。That is, when the nut member 12 is fastened to the sheet metal fitting 3, the adhesive capsule 14 is pressed from both sides between the flange portion 12 b of the nut member 12 and the tip of the sheet metal fitting 3, as shown in FIG. Will be done. Therefore, as shown in FIG. 3, the capsule 14a is broken and the adhesive 14b flows out. At this time, since the hole 13b of the water stop member 13 is set to be substantially the same as the outer diameter of the tip of the sheet metal fitting 3, the tip of the sheet metal fitting 3 is inserted into the hole 13b by tightening the nut member 12. Moreover, since the outer surface of the sheet metal fitting 3 has a frustoconical shape in which the diameter gradually increases toward the right in the figure, the nut member 12 is tightened so that the nut member 12 is completely adhered to the inner peripheral surface of the hole 13b. Therefore, the adhesive 14b flowing out from the capsule 14a is confined in the space surrounded by the collar portion 12b, the water blocking member 13 and the sheet metal fitting 3, and this space is gradually tightened by tightening the nut member 12. As the adhesive 14b shrinks, almost the entire amount of the adhesive 14b flows into the threaded portion between the nut member 12 and the separator 4 and the threaded portion between the sheet pile metal fitting 3 and the separator 4, and is solidified there. It will be.
【００４１】 この接着剤１４ｂの固化により、ナット部材１２の緩みが完全に防止されると ともに、万一矢板控金具３の内部に水が浸入してきても、セパレータ４の外周面 を伝わってピーコン５側に漏れ出すのを完全に防止することができる。The solidification of the adhesive 14b completely prevents the nut member 12 from loosening, and even if water gets into the sheet metal fitting 3, it will travel along the outer peripheral surface of the separator 4 and the pecon will be removed. It can be completely prevented from leaking to the 5 side.
【００４２】 このようにしてピーコン５の位置を固定したならば、ピーコン５の外面側に型 枠６を配置し、型枠６を貫通する雄ねじ部５ａに、図示しない締付金具を装着し て型枠６を固定する。そしてその後、型枠６と山留め壁との間にコンクリートを 打設する。After fixing the position of the pecon 5 in this way, the form 6 is arranged on the outer surface side of the pecon 5, and the male screw portion 5a penetrating the form 6 is fitted with a tightening fitting (not shown). The mold 6 is fixed. Then, concrete is placed between the formwork 6 and the retaining wall.
【００４３】 ところで、コンクリートを打設すると、各止水部材１１，１３は、打設したコ ンクリートからの圧力により、外面側からほぼ均一に押圧されて弾性的に縮小変 形し、コンクリートの固化後、その弾性復帰力によりコンクリートを常時押圧す ることになる。このため、コンクリートとの間で完全な密着性が得られ、万一水 が浸入してきても、いずれかの止水部材１１，１３によりそれ以上のピーコン５ 側への浸入を防止することができ、水漏れを完全に防止することができる。また 、止水部材１１，１３を非加硫ブチルゴムで形成した場合には、物理的な密着性 のみならず、非加硫ブチルゴム中のカルボキシル基とセメント中のＣａＯ成分と が反応してイオン結合し、化学的に強固に接着一体化される。このため、より完 全な止水効果が得られる。By the way, when concrete is poured, the water blocking members 11 and 13 are pressed substantially uniformly from the outer surface side by the pressure from the placed concrete to elastically contract and deform, thereby solidifying the concrete. After that, the elastic restoring force constantly presses the concrete. For this reason, perfect adhesion with concrete can be obtained, and even if water invades, either of the water blocking members 11 and 13 can prevent further infiltration to the PECON 5 side. , Can completely prevent water leakage. When the water blocking members 11 and 13 are made of non-vulcanized butyl rubber, not only physical adhesion but also the carboxyl group in the non-vulcanized butyl rubber reacts with the CaO component in the cement to cause an ionic bond. Then, it is chemically and firmly bonded and integrated. Therefore, a more complete waterproofing effect can be obtained.
【００４４】 図４は、本考案の第２実施例を示すもので、接着剤カプセル１４を止水部材１ ３の内部に組込むようにしたものである。 なお、その他の点については、前記第１実施例と同一構成となっており、作用 も同一である。FIG. 4 shows a second embodiment of the present invention, in which the adhesive capsule 14 is incorporated into the water blocking member 13. In other respects, the configuration is the same as that of the first embodiment and the operation is the same.
【００４５】 しかして、本実施例の場合にも、ナット部材１２を締付ければ接着剤カプセル １４に押圧力が加わり、カプセル１４ａを破って接着剤１４ｂを流出させること ができ、前記第１実施例と同様の効果が得られるとともに、接着剤カプセル１４ が外部に露出してしないので、不用意にカプセル１４ａが破れて接着剤１４ｂが 流出するのを防止することができる。Even in the case of this embodiment, therefore, if the nut member 12 is tightened, a pressing force is applied to the adhesive capsule 14, and it is possible to break the capsule 14a and allow the adhesive 14b to flow out. The same effect as the example is obtained, and since the adhesive capsule 14 is not exposed to the outside, it is possible to prevent the capsule 14a from being accidentally broken and the adhesive 14b from flowing out.
【００４６】 図５は、本考案の第３実施例を示すもので、止水部材１３を、ナット部材１２ の六角ナット部１２ａと鍔部１２ｂとの連結部分に配設し、この止水部材１３の 六角ナット部１２ａ側の側面を、金属または合成樹脂製の補強部材２０で補強す るとともに、止水部材１３の鍔部１２ｂ側の側面を、鍔部１２ｂに配した接着剤 カプセル１４で補強するようにしたものである。 なお、その他の点については、前記第１実施例と同一構成となっており、作用 も同一である。FIG. 5 shows a third embodiment of the present invention, in which the water blocking member 13 is arranged at the connecting portion between the hexagonal nut portion 12a and the flange portion 12b of the nut member 12, The side surface of the hexagonal nut portion 12a of 13 is reinforced with a reinforcing member 20 made of metal or synthetic resin, and the side surface of the water blocking member 13 on the flange portion 12b side is provided with an adhesive capsule 14 arranged on the flange portion 12b. It is designed to be reinforced. In other respects, the configuration is the same as that of the first embodiment and the operation is the same.
【００４７】 しかして、前記第１実施例および第２実施例の場合には、雄ねじ部材２の溶接 座２ａあるいはナット部材１２の鍔部１２ｂが、止水部材１１，１３の補強部材 として機能するので、止水部材１１，１３を非加硫ブチルゴムのような軟らかい 素材で形成しても、止水部材１１，１３が打設したコンクリートにより不用意に 座屈することはないが、止水部材１３をナット部材１２の六角ナット部１２ａに 配置し、しかも止水部材１３を大径にした場合には、不用意に座屈するおそれが ある。However, in the case of the first and second embodiments, the welding seat 2a of the male screw member 2 or the flange portion 12b of the nut member 12 functions as a reinforcing member for the water blocking members 11 and 13. Therefore, even if the water blocking members 11 and 13 are made of a soft material such as non-vulcanized butyl rubber, the water blocking members 11 and 13 do not inadvertently buckle due to the concrete placed, Is placed on the hexagonal nut portion 12a of the nut member 12 and the water blocking member 13 has a large diameter, there is a risk of inadvertent buckling.
【００４８】 ところが、本実施例のように、止水部材１３の一側面に補強部材２０を配した 場合には、止水部材１３の座屈を完全に防止することができる。補強部材２０を 止水部材１３の内部に埋設するようにしても同様の効果が期待できる。However, when the reinforcing member 20 is arranged on one side surface of the water blocking member 13 as in this embodiment, the buckling of the water blocking member 13 can be completely prevented. Even if the reinforcing member 20 is embedded in the water blocking member 13, the same effect can be expected.
【００４９】 図６は、本考案の第４実施例を示すもので、ナット部材１２の鍔部１２ｂに、 内面が鍔部１２ｂの外端面とほぼ面一の補強部材４０を固定するとともに、この 補強部材４０内に、ドーナツ円板状の止水部材１３を鍔部１２ｂの端面に亘って 接着固定し、かつ止水部材１３の孔１３ｂ内に、先端を止水部材１３から突出さ せた状態で接着剤カプセル１４を固定し、さらに補強部材４０の外縁折曲げ部４ ０ａを、止水部材１３の板厚よりも長寸法に設定するようにしたものである。 なお、その他の点については、前記第１実施例と同一構成となっており、作用 も同一である。FIG. 6 shows a fourth embodiment of the present invention, in which a reinforcing member 40 having an inner surface substantially flush with the outer end surface of the collar portion 12b is fixed to the collar portion 12b of the nut member 12. In the reinforcing member 40, the donut disk-shaped water stopping member 13 was adhesively fixed over the end face of the collar portion 12b, and the tip was protruded from the water stopping member 13 into the hole 13b of the water stopping member 13. In this state, the adhesive capsule 14 is fixed, and the outer edge bent portion 40a of the reinforcing member 40 is set to be longer than the plate thickness of the water blocking member 13. In other respects, the configuration is the same as that of the first embodiment and the operation is the same.
【００５０】 しかして、本実施例の場合にも、止水部材１３が補強部材４０で補強されるの で、前記第３実施例と同様の効果が得られるとともに、補強部材４０の外縁折曲 げ部４０ａが、止水部材１３よりも突出しているので、止水部材１３を非加硫ブ チルゴムで形成しても、止水部材１３が相互に接触して分離不可能となることが ない。In the case of the present embodiment as well, since the water blocking member 13 is reinforced by the reinforcing member 40, the same effect as in the third embodiment can be obtained and the outer edge of the reinforcing member 40 is bent. Since the barbed portion 40a projects more than the water blocking member 13, even if the water blocking member 13 is made of non-vulcanized rubber, the water blocking members 13 do not come into contact with each other and become inseparable. .
【００５１】 図７は、本考案の第５実施例を示すもので、図６に示すナット部材１２内に凹 陥部５１を設け、この凹陥部５１内に接着剤カプセル１４を配設したものである 。 なお、その他の点については、前記第４実施例と同一構成となっており、作用 も同一である。FIG. 7 shows a fifth embodiment of the present invention, in which a concave portion 51 is provided in the nut member 12 shown in FIG. 6, and the adhesive capsule 14 is arranged in the concave portion 51. Is. In other respects, the structure is the same as that of the fourth embodiment and the operation is the same.
【００５２】 しかして、接着剤カプセル１４をナット部材１２の凹陥部５１内に配設するこ とにより、矢板控金具３で接着剤カプセル１４が押圧された際に、図４の場合以 上に押圧力が確実に接着剤カプセル１４に伝えられ、流出した接着剤１４ｂを、 より確実にねじ部に送り込むことができる。Therefore, by disposing the adhesive capsule 14 in the recessed portion 51 of the nut member 12, when the adhesive capsule 14 is pressed by the sheet metal fitting 3, the adhesive capsule 14 can be provided more than in the case of FIG. The pressing force is surely transmitted to the adhesive capsule 14, and the adhesive 14b that has flowed out can be more reliably sent to the screw portion.
【００５３】 図８は、本考案の第６実施例を示すもので、ナット部材１２の鍔部１２ｂを薄 板円板状に形成するとともに、この鍔部１２ｂの両面に止水部材１３を接着固定 し、かつ鍔部１２ｂに設けた複数のピン６１の先端を、止水部材１３から突出さ せ、さらにナット部材１２の凹陥部５１内に、接着剤カプセル１４に代えて、軟 質プラスチックあるいは軟質ゴム製等の極めて軟い軟質筒材６２を配設するよう にしたものである。 なお、その他の点については、前記第５実施例と同一構成となっており、作用 も同一である。FIG. 8 shows a sixth embodiment of the present invention, in which the flange portion 12b of the nut member 12 is formed into a thin disk shape and the water blocking member 13 is adhered to both surfaces of the flange portion 12b. The tips of a plurality of pins 61 that are fixed and are provided on the collar portion 12b are projected from the water blocking member 13. Further, in the concave portion 51 of the nut member 12, instead of the adhesive capsule 14, soft plastic or An extremely soft soft tubular member 62 made of soft rubber or the like is arranged. In other respects, the structure is the same as that of the fifth embodiment and the operation is the same.
【００５４】 しかして、軟質筒材６２を矢板控金具３で押圧すると、凹陥部５１のテーパに そって縮径して、内周面がセパレータ４の長さ調節用雄ねじ部４ａの外周面に倣 って変形し、接着剤１４ｂと同様の水密性が得られる。また、ピン６１により、 図６および図７の補強部材４０の外縁折曲げ部４０ａと同様の効果が得られ、し かも止水部材１３とコンクリートとの接触面積を拡大することができる。When the soft tubular material 62 is pressed by the sheet metal fitting 3, the diameter of the soft tubular material 62 is reduced along the taper of the concave portion 51, and the inner peripheral surface becomes the outer peripheral surface of the length adjusting male screw portion 4 a of the separator 4. Following the deformation, the watertightness similar to that of the adhesive 14b is obtained. Further, the pin 61 has the same effect as the outer edge bent portion 40a of the reinforcing member 40 of FIGS. 6 and 7, and it is possible to increase the contact area between the water blocking member 13 and the concrete.
【００５５】 図９および図１０は、本考案の第７実施例を示すもので、薄板鋼板の板金加工 あるいはプラスチックの成形加工等により、外縁折曲げ部７０ａを有する補強部 材７０，接着剤カプセル１４あるいは軟質筒材６２の収容部７１，およびナット 部７２を一体に構成し、補強部材７０と収容部７１との間に、ナット部７２を手 の力のみで矢板控金具３に締付ける際の手掛け部を兼ねる補強リブ７３を所要数 設けるようにしたものである。 なお、その他の点については、前記第１実施例と同一構成となっており、作用 も同一である。9 and 10 show a seventh embodiment of the present invention, in which a reinforcing member 70 having an outer edge bent portion 70a and an adhesive capsule are formed by sheet metal working of a thin steel plate or plastic molding. 14 or the container portion 71 of the soft tubular member 62 and the nut portion 72 are integrally formed, and when the nut portion 72 is fastened to the sheet pile metal fitting 3 between the reinforcing member 70 and the housing portion 71 by only manual force. A required number of reinforcing ribs 73 that also serve as a handle portion are provided. In other respects, the configuration is the same as that of the first embodiment and the operation is the same.
【００５６】 しかして、補強部材７０，収容部７１およびナット部材７２を一体に設けるこ とにより、コストダウンを図ることができ、また補強リブ７３により、板厚を薄 くできるとともに、手の力のみでも大きな締付け力が得られる。By integrally providing the reinforcing member 70, the accommodating portion 71, and the nut member 72, the cost can be reduced, and the reinforcing ribs 73 can reduce the plate thickness and force the hand. A large tightening force can be obtained only by itself.
【００５７】 図１１は、本考案の第８実施例を示すもので、薄板鋼板の板金加工あるいはプ ラスチックの成形加工等により、外縁折曲げ部８０ａを有する補強部材８０とナ ット部８１とを一体に構成し、補強部材８０に、非加硫ブチルゴム製の止水部材 １３を接着剤等により固定するとともに、止水部材１３の外面に、ＣａＯを含む 粉末８２，例えばセメント粉末を付着させるようにしたものである。 なお、その他の点については、前記第１実施例と同一構成となっており、作用 も同一である。FIG. 11 shows an eighth embodiment of the present invention, in which a reinforcing member 80 having an outer edge bent portion 80a and a nut portion 81 are formed by sheet metal working of a thin steel plate or plastic forming. The water blocking member 13 made of non-vulcanized butyl rubber is fixed to the reinforcing member 80 with an adhesive or the like, and the powder 82 containing CaO, for example, cement powder is attached to the outer surface of the water blocking member 13. It was done like this. In other respects, the configuration is the same as that of the first embodiment and the operation is the same.
【００５８】 しかして、止水部材１３が非加硫ブチルゴムで形成され、その孔１３ｂが矢板 控金具３端面の外形よりも小形となっているので、外縁折曲げ部８０ａを手で持 ってナット部８１を矢板控金具３に締付けると、止水部材１３は、一端が矢板控 金具３に固定された状態で、恰も糸をセパレータ４に巻付けるようにしてその長 さ調節用雄ねじ部４ａの外周面に巻付けられ、完全な止水効果が得られる。この 効果は、止水部材１３の外径側への変形が外縁折曲げ部８０ａで規制されている ので、より確実なものとなっている。しかも、止水部材１３の外面には、ＣａＯ を含む粉末８２が付着していてベト付かないようになっているので、止水部材１ ３同士が直接接触しても、両者が分離不可能あるいは困難となることがなく、取 扱いが極めて容易となる。その上、ＣａＯを含む粉末８２であるので、コンクリ ート打設後は、この粉末８２を付着させない場合と同様、非加硫ブチルゴム中の カルボキシル基とコンクリート中のＣａＯ成分とが反応してイオン結合し、化学 的な強固な接着一体化が阻害されることは全くない。Since the water blocking member 13 is made of non-vulcanized butyl rubber and the hole 13b is smaller than the outer shape of the end face of the sheet pile holding metal fitting 3, the outer edge bent portion 80a should be held by hand. When the nut portion 81 is fastened to the sheet metal fitting 3, the water blocking member 13 has its one end fixed to the sheet metal fitting 3, and the length adjusting male screw portion 4a is formed by winding the thread around the separator 4. It is wrapped around the outer peripheral surface of the to obtain a perfect water-stop effect. This effect is more reliable because the deformation of the water blocking member 13 toward the outer diameter side is restricted by the outer edge bent portion 80a. Moreover, since the powder 82 containing CaO 3 is attached to the outer surface of the water blocking member 13 so as not to be sticky, even if the water blocking members 13 come into direct contact with each other, they cannot be separated from each other or It will not be difficult and will be extremely easy to handle. Moreover, since the powder 82 contains CaO, after the concrete is cast, the carboxyl group in the non-vulcanized butyl rubber and the CaO component in the concrete react with each other in the same manner as when the powder 82 is not adhered. It does not interfere with the bonding and the chemically strong adhesive integration.
【００５９】 図１２は、本考案の第９実施例を示すもので、前記第８実施例の構成において 、止水部材１３と矢板控金具３との間に、座金状の押圧板９０を介装するように したものである。 なお、その他の点については、前記第８実施例と同一構成となっており、作用 も同一である。FIG. 12 shows a ninth embodiment of the present invention. In the configuration of the eighth embodiment, a washer-like pressing plate 90 is interposed between the water blocking member 13 and the sheet pile metal fitting 3. It was designed to be worn. The other points are the same as those of the eighth embodiment, and the operation is the same.
【００６０】 しかして、押圧板９０を用いた場合には、止水部材１３が、恰も糸を巻付ける ようにしてセパレータ４に巻付けられるといった効果は、それほど期待はできな いが、押圧板９０により止水部材１３が広い面積で押圧されるので、その変形量 が大きくなり、孔１３ｂを縮径させて長さ調節用雄ねじ部４ａの外周面に密着さ せることができる。このため、第８実施例と同様の止水効果が得られる。However, when the pressing plate 90 is used, the effect that the water blocking member 13 is wound around the separator 4 like winding a thread is not so expected, but the pressing plate is not so expected. Since the water blocking member 13 is pressed by a wide area by 90, the deformation amount thereof becomes large, and the hole 13b can be reduced in diameter to be brought into close contact with the outer peripheral surface of the length adjusting male screw portion 4a. Therefore, the same water blocking effect as that of the eighth embodiment can be obtained.
【００６１】 なお、前記各実施例においては、止水部材１１と止水部材１３との両方を用い る場合について説明したが、必要に応じいずれか一方を省略するようにしてもよ い。また、接着剤カプセル１４は、必ずしもナット部材１２と一体である必要は なく、ナット部材１２と別体でもよい。また、接着剤カプセル１４を矢板控金具 ３と溶接座２ａとの間に介装するようにしてもよい。In each of the above embodiments, the case where both the water blocking member 11 and the water blocking member 13 are used has been described, but either one may be omitted if necessary. Further, the adhesive capsule 14 does not necessarily have to be integrated with the nut member 12 and may be a separate body from the nut member 12. Further, the adhesive capsule 14 may be interposed between the sheet metal fitting 3 and the welding seat 2a.

以上説明したように、本考案の請求項１に係る考案は、雄ねじ部材と矢板控金 具との間または矢板控金具とナット部材との間に、接着剤カプセルを介装するよ うにしているので、矢板控金具あるいはナット部材を締付けることにより、カプ セルが破れて接着剤が流出し、流出した接着剤によりねじ部を完全にシールする ことができる。このため、矢板控金具の内部を通って水が漏れ出すのを防止する ことができるとともに、ねじ部の緩みも防止することができる。 As described above, in the invention according to claim 1 of the present invention, the adhesive capsule is interposed between the male screw member and the sheet pile metal retainer or between the sheet metal retainer and the nut member. Therefore, by tightening the sheet metal fitting or the nut member, the capsule is broken and the adhesive flows out, and the threaded part can be completely sealed by the flowing out adhesive. Therefore, it is possible to prevent water from leaking out through the inside of the sheet metal fitting, and also to prevent loosening of the screw portion.
【００６３】 また、本考案の請求項２に係る考案は、雄ねじ部材と矢板控金具との間に止水 部材を介装し、この止水部材は、外形が矢板控金具よりも大形で弾性を有してい るので、雄ねじ部材と矢板控金具との間が完全にシールされるとともに、外周面 が打設されるコンクリートと完全に密着するので、矢板控金具の内部および外周 部を伝わって水が浸入するのを、完全に防止することができる。Further, in the invention according to claim 2 of the present invention, a water blocking member is interposed between the male screw member and the sheet pile metal fitting, and the water blocking member has a larger outer shape than the sheet metal fitting. Since it has elasticity, the male screw member and the sheet pile metal fitting are completely sealed, and the outer peripheral surface is in close contact with the concrete to be cast, so that it can be transmitted inside and outside the sheet metal fitting. Water can be completely prevented from entering.
【００６４】 また、本考案の請求項３に係る考案は、ナット部材に、矢板控金具よりも大形 で弾性を有する止水部材を設けているので、矢板控金具の外周面を伝わって浸入 してきた水を、この止水部材により完全に止めることができる。Further, in the invention according to claim 3 of the present invention, the nut member is provided with the water blocking member which is larger and has elasticity than the sheet pile holding metal fitting, so that the penetration penetrates along the outer peripheral surface of the sheet pile holding fitting. The stopped water can be stopped completely by this water stop member.
