Description

モルタル用接着補助器具及び当該接着補助器具を備えるモルタル用接着補助システムAdhesive auxiliary device for mortar and adhesion auxiliary system for mortar provided with the auxiliary adhesive device
　本発明は、コンクリート構造体に対するモルタルの接着を補助するに適したモルタル用接着補助器具及び当該接着補助器具を備えるモルタル用接着補助システムに関する。 The present invention relates to a mortar adhesion assisting device suitable for assisting adhesion of mortar to a concrete structure and a mortar adhesion assisting system including the adhesion assisting device.
　従来、コンクリート構造体を建造するにあたっては、互いに対向する２枚の型枠を複数本のスペーサボルトでもって所定間隔に維持する。このような状態において、生コンクリートを当該２枚の型枠の間に打ち込んだ後硬化させ、その後、当該２枚の型枠を除去することで、コンクリート構造体を建造する。 Conventionally, when building a concrete structure, two molds facing each other are maintained at a predetermined interval with a plurality of spacer bolts. In such a state, the ready-mixed concrete is driven between the two molds and cured, and then the two molds are removed to construct a concrete structure.
　また、このように建造したコンクリート建造体は、型枠を除去しただけの状態にあるため、コンクリート構造体の表面の見栄えは良くない。このため、この見栄えを改善するために、通常、モルタル壁が、コンクリート建造体の表面にモルタルの塗布及びその硬化でもって形成される。 Also, since the concrete structure constructed in this way is in a state where the formwork has been removed, the appearance of the surface of the concrete structure is not good. For this reason, in order to improve this appearance, mortar walls are usually formed on the surface of a concrete structure by applying mortar and curing it.
　ここで、上述のように形成されるモルタル壁は経年変化する。これに伴い、当該モルタル壁のコンクリート建造体の表面に対する接着状態が、経年的に劣化すると、当該モルタル壁が、コンクリート建造体の表面から剥がれ落ち易くなる。 Here, the mortar wall formed as described above changes over time. Along with this, when the adhesion state of the mortar wall to the surface of the concrete structure deteriorates with time, the mortar wall is easily peeled off from the surface of the concrete structure.
　これに対しては、下記特許文献１に記載のモルタル接着補助器具が提案されている。当該モルタル接着補助器具は、円錐台状の埋栓部と、当該埋栓部上に形成してなる複数のループ状係止部とでもって、一体的に形成されている。 For this, a mortar adhesion assisting device described in Patent Document 1 below has been proposed. The mortar adhesion assisting device is integrally formed with a truncated cone-shaped plug portion and a plurality of loop-shaped locking portions formed on the plug portion.
　このように形成してなるモルタル接着補助器具を用いて、駆体コンクリートにモルタルを塗布するにあたっては、接着剤が埋栓部の外周面や底面に塗布される。然る後、当該埋栓部が、躯体コンクリートの表面に後述のように形成されるコーン跡内に埋設される。このとき、当該埋設は、係止部を躯体コンクリートの表面から露出させるように行われる。 In applying the mortar to the precursor concrete using the mortar adhesion assisting device formed in this way, the adhesive is applied to the outer peripheral surface and the bottom surface of the plug portion. Thereafter, the plug portion is embedded in a cone mark formed on the surface of the frame concrete as described later. At this time, the embedding is performed so that the locking portion is exposed from the surface of the concrete frame.
　ここで、上述したコーン跡は次のようにして駆体コンクリートに形成される。即ち、２枚の型枠内にコーン跡に対応する外形形状を有するコネクターを設け、然る後、生コンクリートを２枚の型枠内にコネクターを介して打ち込んで硬化させることで、駆体コンクリートを形成する。ついで、型枠を駆体コンクリートからコネクターと共に除去すると、駆体コンクリートが、コネクターに対応する形状のコーン跡を有するように形成される。 Here, the above-mentioned cone mark is formed on the body concrete as follows. That is, a connector having an outer shape corresponding to the cone mark is provided in the two molds, and then the concrete is driven into the two molds via the connector and hardened, thereby driving the concrete. Form. Then, when the formwork is removed from the precursor concrete together with the connector, the precursor concrete is formed to have a cone mark having a shape corresponding to the connector.
　上述のようにモルタル接着補助器具が躯体コンクリートのコーン跡に埋設された後、生モルタルが、モルタル接着補助器具及び駆体コンクリートの双方の表面に亘るように塗布される。 As described above, after the mortar adhesion assisting device is embedded in the cone mark of the reinforced concrete, the raw mortar is applied so as to cover both the surfaces of the mortar adhesion assisting device and the hard concrete.
　このように生モルタルが塗布された段階では、当該生モルタルが未硬化の状態にあるため、当該生モルタルは、モルタル接着補助器具の係止部内に浸入する。従って、このような状態で生モルタルが硬化すると、モルタル接着補助器具は、硬化したモルタルに対して高いアンカー効果を発揮し得る。このことは、モルタルの駆体コンクリートからの剥がれ落ちを未然に防止し得ることを意味する。 </ RTI> Since the raw mortar is in an uncured state at the stage where the raw mortar is applied in this way, the raw mortar enters the engaging portion of the mortar adhesion assisting device. Therefore, when raw mortar hardens | cures in such a state, the mortar adhesion auxiliary tool can exhibit a high anchor effect with respect to the hardened mortar. This means that the mortar can be prevented from peeling off from the concrete concrete.

　しかしながら、上述のように構成してなるモルタル接着補助器具を、モルタルの駆体コンクリートに対する塗布にあたり利用するためには、上述のように型枠に用いられたコネクターを型枠の駆体コンクリートから取り外すという余分な作業が必要となる。 However, in order to use the mortar adhesion assisting device configured as described above for applying mortar to concrete concrete, the connector used for the mold as described above is removed from the concrete concrete of the mold. This extra work is required.
　また、上述のようにコネクターを除去した上で、モルタル接着補助器具を改めてコーン跡に取り付ける作業が必要となり、面倒である。 Also, after removing the connector as described above, it is necessary to reattach the mortar adhesion assisting device to the cone mark, which is troublesome.
　また、上述のように取り外したコネクターは、数回使用された後には、廃棄される。従って、当該コネクターは廃棄物としての環境汚染を招くという不具合を生ずる。 Also, the connector removed as described above is discarded after being used several times. Therefore, the connector causes a problem of causing environmental pollution as waste.
　そこで、本発明は、以上のようなことに対処するため、モルタルのコンクリート構造体からの剥がれ落ちを、余分な作業や廃材部品の発生を伴うことなく、未然に防止し得るようにしたモルタル用接着補助器具及び当該接着補助器具を備えるモルタル用接着補助システムを提供することを目的とする。 Therefore, the present invention is for a mortar that can prevent the mortar from peeling off from the concrete structure without extra work or generation of waste parts in order to deal with the above-described problems. It aims at providing the adhesion auxiliary system for mortar provided with the adhesion auxiliary instrument and the said adhesion auxiliary instrument.
　上記課題の解決にあたり、本発明に係るモルタル用接着補助器具は、合成樹脂により一体的に形成してなるものである。 In solving the above-mentioned problems, the mortar adhesion assisting device according to the present invention is integrally formed of a synthetic resin.
　当該モルタル用接着補助器具において、
　基板（２１０、３１０）と、当該基板にその両面の一方の面から突出するように分散して形成される複数の面側係合片（２２０、３４０）とを備えることを特徴とする。 In the adhesion aid for mortar,
It is characterized by comprising a substrate (210, 310) and a plurality of surface side engagement pieces (220, 340) formed on the substrate so as to protrude from one surface of both surfaces thereof.

　従って、基板が、複数の面側係合片をコンクリート体の表面から離れる方向に突出させるように、当該コンクリート体の表面に装着された状態にて、生モルタルが当該モルタル用接着補助器具を介しコンクリート体の表面に塗布されると、当該モルタル用接着補助器具が、生モルタルに埋設されることになる。 Therefore, in a state where the substrate is mounted on the surface of the concrete body so that the plurality of surface-side engagement pieces protrude in a direction away from the surface of the concrete body, the raw mortar passes through the mortar adhesion assisting device. When applied to the surface of the concrete body, the mortar adhesion assisting tool is embedded in the raw mortar.
　このため、生モルタルが、基板の上記一方の面及び外周部に亘り一様に密着するとともに、複数の面側係合片に密着してしっかりと係合し得ることから、生モルタルが硬化してモルタル壁として形成されても、当該モルタル壁は、コンクリート体の表面に対し、当該モルタル用接着補助器具により、その基板及び複数の面側係合片でもってしっかりと保持され得る。このため、当該モルタル壁は、経年的にも、コンクリート体の表面から剥がれにくくなる。このことは、当該モルタル用接着補助器具は、コンクリート体とモルタル壁との間に埋設されたとき、複数の面側係合片にてモルタル壁の内部にしっかりと係合することで、当該モルタル壁のコンクリート体に対する接着力を高めるという優れたアンカー効果を良好に発揮し得ることを意味する。 For this reason, the raw mortar hardens because the raw mortar uniformly adheres to the one surface and the outer peripheral portion of the substrate and can be firmly in close contact with the plurality of surface side engagement pieces. Even if the mortar wall is formed as a mortar wall, the mortar wall can be firmly held to the surface of the concrete body with the substrate and the plurality of surface side engagement pieces by the mortar bonding aid. For this reason, the said mortar wall becomes difficult to peel from the surface of a concrete body also aging. This is because when the mortar adhesion assisting device is embedded between the concrete body and the mortar wall, the mortar is firmly engaged with the inside of the mortar wall by a plurality of surface side engagement pieces. It means that the excellent anchor effect of increasing the adhesive strength of the wall to the concrete body can be exhibited well.
　また、当該モルタル用接着補助器具は、基板と複数の面側係合片のみからなるため、余分な作業や廃材部品の発生を伴うことのない非常に簡単でコンパクトな構成にて提供され得る。 Also, since the mortar adhesion assisting device is composed of only the substrate and the plurality of surface side engaging pieces, it can be provided in a very simple and compact configuration without any extra work or generation of waste material parts.
　また、基板は、文字通り、板であるため、コンクリート体の表面に塗布した生モルタルは、その表面にて、モルタル用接着補助器具に起因して凹凸形状に変化することなく、ほぼ一様な厚さを維持し得る。従って、基板が薄い程、塗布した生モルタルの厚さは、薄くし得るから、生モルタルの塗布量の軽減に役立つ。 In addition, since the substrate is literally a plate, the raw mortar applied to the surface of the concrete body has a substantially uniform thickness on the surface without changing to a concavo-convex shape due to the adhesion aid for mortar. You can keep it. Accordingly, the thinner the substrate, the thinner the applied raw mortar can be, which helps reduce the amount of raw mortar applied.
　また、本発明は、上述したモルタル用接着補助器具において、
　複数の面側係合片は、基板に上記一方の面から湾曲状に突出するように分散して形成されることを特徴とする。 In addition, the present invention provides the above-described adhesion aid for mortar,
The plurality of surface-side engagement pieces are formed to be distributed on the substrate so as to protrude in a curved shape from the one surface.
　このように複数の面側係合片の形状を湾曲状にすることで、生モルタルが、上述のごとく、モルタル用接着補助器具を介しコンクリート体の表面に塗布されたとき、当該生モルタルは、複数の湾曲状面側係合片と基板との間にも入り込んで、当該複数の湾曲状面側係合片とより一層良好にと係合し得る。その結果、当該モルタル用接着補助器具が、その複数の湾曲状面側係合片及び当該複数の湾曲状面側係合片と基板との間にて、モルタル壁としっかりと係合して当該モルタル壁をコンクリート体の表面から長期に亘り離脱不能に維持することができ、上述した本発明の作用効果をより一層向上し得る。 Thus, by making the shape of the plurality of surface side engagement pieces curved, when the raw mortar is applied to the surface of the concrete body via the adhesion aid for mortar as described above, the raw mortar is It can also enter between the plurality of curved surface side engaging pieces and the substrate and engage with the plurality of curved surface side engaging pieces even better. As a result, the mortar adhesion assisting instrument is firmly engaged with the mortar wall between the plurality of curved surface side engaging pieces and the plurality of curved surface side engaging pieces and the substrate. The mortar wall can be maintained so as not to be detached from the surface of the concrete body for a long period of time, and the above-described effects of the present invention can be further improved.
　また、本発明は、上述したモルタル用接着補助器具において、
　基板は、その中央部に中央孔部（２１１，２１１ａ、３１１、３１１ａ）を形成するとともに当該中央孔部の外周側にて複数の長手状開口部（２１３ａ～２１３ｊ、３１３ａ～３１３ｋ、３１３ｎ）を分散して形成してなり、
　複数の面側係合片は、上記複数の長手状開口部に対応するように複数の係合片群（２２０ａ、２２０ｂ、３４０ａ、３４０ｂ）に分割して基板の上記一方の面に形成されており、
　複数の係合片群は、それぞれ、その各面側係合片にて、上記複数の長手状開口部のうちの各対応長手状開口部をその幅方向に跨ぐように当該各対応長手状開口部の長手方向に間隔をおいて形成されていることを特徴とする。 In addition, the present invention provides the above-described adhesion aid for mortar,
The substrate has a central hole (211, 211 a, 311, 311 a) formed in the center thereof and a plurality of longitudinal openings (213 a to 213 j, 313 a to 313 k, 313 n) on the outer peripheral side of the central hole. Formed in a dispersed manner,
The plurality of surface side engagement pieces are formed on the one surface of the substrate by being divided into a plurality of engagement piece groups (220a, 220b, 340a, 340b) so as to correspond to the plurality of longitudinal openings. And
Each of the plurality of engagement piece groups has a corresponding longitudinal opening so as to straddle the corresponding longitudinal opening of the plurality of longitudinal openings in the width direction at each surface side engagement piece. It is characterized by being formed at intervals in the longitudinal direction of the part.
　このように複数の面側係合片が、湾曲状にて、複数の長手状開口部に対応するように複数の係合片群に分割して基板の一方の面に形成されており、複数の係合片群が、それぞれ、その各面側係合片にて、複数の長手状開口部のうちの各対応長手状開口部をその幅方向に跨ぐように当該各対応長手状開口部の長手方向に間隔をおいて形成されている。 As described above, the plurality of surface-side engagement pieces are curved and formed on one surface of the substrate by being divided into a plurality of engagement piece groups so as to correspond to the plurality of longitudinal openings. Each of the corresponding longitudinal opening portions of the plurality of longitudinal opening portions so as to straddle each corresponding longitudinal opening portion in the width direction thereof. They are formed at intervals in the longitudinal direction.
　従って、生モルタルが、上述のように、当該モルタル用接着補助器具を介しコンクリート体の表面に塗布されたとき、当該生モルタルは、複数の湾曲状面側係合片と基板との間だけでなく複数の長手状開口部内にも浸入することとなる。 Therefore, when the raw mortar is applied to the surface of the concrete body via the mortar bonding aid as described above, the raw mortar is only between the curved surface side engagement pieces and the substrate. Instead, it also penetrates into a plurality of longitudinal openings.
　これにより、生モルタルが硬化してモルタル壁となったとき、当該モルタル用接着補助器具は、その複数の湾曲状面側係合片及び当該複数の湾曲状面側係合片と基板との間だけでなく、基板の複数の長手状開口部の内部にて、モルタル壁と係合することとなり、当該モルタル壁をコンクリート体の表面から長期に亘りより一層離脱不能に維持し得る。その結果、上述した本発明の作用効果より一層向上され得る。 Thus, when the raw mortar hardens to become a mortar wall, the mortar adhesion assisting tool includes the plurality of curved surface side engaging pieces and the plurality of curved surface side engaging pieces between the substrate and the curved surface side engaging pieces. In addition, the mortar wall is engaged with the inside of the plurality of longitudinal openings of the substrate, and the mortar wall can be kept more detachable from the surface of the concrete body for a long time. As a result, the effects of the present invention described above can be further improved.
　また、本発明は、上述したモルタル用接着補助器具において、
　基板の外周部からその周方向に亘り間隔をおいて放射状に延出するように形成してなる複数の外周側係合片（２５０、３２０）を具備することを特徴とする。 In addition, the present invention provides the above-described adhesion aid for mortar,
It comprises a plurality of outer peripheral side engaging pieces (250, 320) formed so as to extend radially from the outer peripheral portion of the substrate at intervals in the circumferential direction.
　このように、複数の外周側係合片が基板の外周部からその周方向に亘り間隔をおいて放射状に延出することで、生モルタルが上述のごとく当該モルタル用接着補助器具を介しコンクリート体の表面に塗布されたとき、当該モルタル用接着補助器具は、複数の外周側係合片によっても、生モルタルと係合する。 As described above, the plurality of outer peripheral side engagement pieces radially extend from the outer peripheral portion of the substrate at intervals in the circumferential direction, so that the raw mortar becomes a concrete body via the mortar adhesion assisting tool as described above. When applied to the surface of the mortar, the mortar adhesion assisting instrument is also engaged with the raw mortar by the plurality of outer peripheral engagement pieces.
　このため、生モルタルが硬化してモルタル壁となったとき、当該モルタル用接着補助器具は、複数の外周側係合片によっても、モルタル壁にその内部にてしっかりと係合する。 For this reason, when raw mortar hardens to become a mortar wall, the mortar adhesion assisting device is firmly engaged with the mortar wall by the plurality of outer peripheral side engagement pieces.
　その結果、当該モルタル用接着補助器具は、基板から突出する複数の係合片でもって、モルタル壁をコンクリート体の表面に支持し得る。その結果、上述した本発明の作用効果がより一層良好に達成され得る。 As a result, the adhesion aid for mortar can support the mortar wall on the surface of the concrete body with a plurality of engagement pieces protruding from the substrate. As a result, the above-described effects of the present invention can be achieved even better.
　また、本発明は、上述したモルタル用接着補助器具において、
　複数の外周側係合片は、それぞれ、基板の外周部からその周方向に亘り間隔をおいて放射状に延出する基部（３２１、３２３）と、当該基部の延出端部から折れ曲がるように延出する折れ曲がり部（３２２）とにより形成されていることを特徴とする。 In addition, the present invention provides the above-described adhesion aid for mortar,
Each of the plurality of outer peripheral engagement pieces extends from the outer peripheral portion of the substrate so as to bend from the base portion (321, 323) extending radially at an interval in the circumferential direction and from the extended end portion of the base portion. It is formed by the bent part (322) which comes out.
　このように複数の外周側係合片を構成することで、当該複数の外周側係合片は、それぞれ、基部及び折れ曲がり部でもって、モルタル壁とより一層良好に係合し得る。その結果、当該モルタル用接着補助器具がコンクリート体に対するモルタル壁の接着力（アンカー効果）をより一層強化し得る。 By configuring the plurality of outer peripheral side engaging pieces in this way, the plurality of outer peripheral side engaging pieces can be engaged with the mortar wall even better with the base portion and the bent portion, respectively. As a result, the mortar adhesion assisting device can further enhance the adhesion (anchor effect) of the mortar wall to the concrete body.
　また、本発明は、上述したモルタル用接着補助器具において、
　基板に上記一方の面から複数の係合片群の内側にて上記中央孔部の周りに間隔をおいて形成される複数のフック（２２０ａ～２２０ｄ、３３０ａ～３３０ｄ）を具備してなり、
　当該複数のフックは、それぞれ、基板の上記一方の面から立ち上がるように延出する立ち上がり部（２２１、３３１）と、当該立ち上がり部から基板の中心側へ折れ曲るように延出する折れ曲がり部（２２２、３３２）とでもって、構成されていることを特徴とする。 In addition, the present invention provides the above-described adhesion aid for mortar,
A plurality of hooks (220a to 220d, 330a to 330d) formed at intervals around the central hole inside the plurality of engagement piece groups from the one surface on the substrate;
Each of the plurality of hooks includes a rising portion (221, 331) extending so as to rise from the one surface of the substrate, and a bent portion extending so as to be bent from the rising portion toward the center of the substrate ( 222, 332).
　このように、複数のフックを基板に形成することで、当該複数のフックが、各立ち上がり部により環状板を包囲した状態にて、弾力に抗して、各折れ曲がり部でもって、環状板を基板との間に挟持し、かつ、基板がその中央孔部にて環状板を介しネジによりコンクリート体に締着されれば、当該モルタル用接着補助器具は、環状板及びネジでもって、コンクリート体に強固に組み付けられ得る。 In this way, by forming a plurality of hooks on the substrate, the plurality of hooks surrounds the annular plate by the rising portions, and the annular plate is formed on the substrate with each bent portion against elasticity. And the substrate is fastened to the concrete body with a screw through the annular plate at the center hole, the mortar adhesion assisting device is attached to the concrete body with the annular plate and the screw. It can be firmly assembled.
　従って、環状板が基板の中央孔部の強度を補助して高める役割を果たし、その結果、モルタル壁のコンクリート体に対する当該モルタル用接着補助器具によるアンカー効果がより一層向上され得る。 Therefore, the annular plate plays a role of assisting and increasing the strength of the central hole portion of the substrate, and as a result, the anchor effect by the mortar adhesion assisting device on the concrete body of the mortar wall can be further improved.
　ここで、上述した構成の複数のフックに加え、基板の外周部からその周方向に亘り間隔をおいて放射状に延出するように形成してなる複数の外周側係合片を具備することで、当該モルタル用接着補助器具によるアンカー効果がさらに向上され得る。 Here, in addition to the plurality of hooks configured as described above, a plurality of outer peripheral engagement pieces formed to extend radially from the outer peripheral portion of the substrate at intervals in the circumferential direction are provided. The anchor effect of the mortar adhesion assisting device can be further improved.
　また、本発明に係るモルタル用接着補助システムは、
　コンクリート体（１０ａ）の表面に形成されるモルタル壁（Ｍ）の前記コンクリート体との接着を補助するためのものである。 In addition, the adhesion assist system for mortar according to the present invention,
This is for assisting adhesion of the mortar wall (M) formed on the surface of the concrete body (10a) with the concrete body.
　当該モルタル用接着補助システムにおいて、
　コネクター（１１０）と、当該コネクターにその表面から突出するように分散して形成される複数の面側係合片（１２０）と、当該複数の面側係合片を包囲するようにコネクターの表面の外周部から延出する薄肉環状連結壁（１３０）と、この連結壁の延出端部から当該連結壁と同一方向へ延出する厚肉環状支持壁（１４０）とを有するように合成樹脂でもって一体的に形成される複数の第１接着補助器具（１００）と、
　中央孔部（２１１、３１１）を形成してなる基板（２１０、３１０）と、当該基板にその両面の一方の面から突出するように上記中央孔部の周囲に分散して形成される複数の面側係合片（２２０、３４０）とを有するように合成樹脂でもって一体的に形成される複数の第２接着補助器具（２００、３００）とを備えており、
　複数の第１接着補助器具は、各厚肉環状支持壁にて、互いに対向して設置してなる両型枠（Ｆ）の一方の型枠（Ｆ）に対向するように、当該一方の型枠側から分散して他方の型枠側に向けて延出する複数のスペーサボルト（１５０）に連結され、かつ、上記一方の型枠を介し各厚肉環状支持壁を各対応のコネクター側へ各対応の薄肉環状連結壁を変形させながら押圧することで、各厚肉環状支持壁にて、複数の面側係合片を包囲するように、各対応のコネクターの表面側外周部から外方に向け半径方向に延出する環状フランジ（１１５）に着座してなり、
　複数の第２接着補助器具は、コンクリート体が両型枠の間に複数のスペーサボルト及び複数の第１接着補助器具を介し打ち込まれる生コンクリートの硬化により形成された後、両型枠の除去後複数の第１接着補助器具とは異なる位置にてコンクリート体の表面に分散して配設され、かつ、それぞれ、上記中央孔部にて、各ネジによりコンクリート体の表面に締着されており、
　モルタル壁が、各複数の第１及び第２の接着補助器具を介しコンクリート体の表面に所定の厚さにて生モルタルを塗布し硬化させることで、形成されていることを特徴とする。 In the adhesive auxiliary system for mortar,
A connector (110), a plurality of surface-side engaging pieces (120) formed in a distributed manner so as to protrude from the surface of the connector, and a surface of the connector so as to surround the plurality of surface-side engaging pieces Synthetic resin so as to have a thin annular connecting wall (130) extending from the outer peripheral portion and a thick annular supporting wall (140) extending from the extending end of the connecting wall in the same direction as the connecting wall. A plurality of first bonding aids (100) formed integrally therewith,
A plurality of substrates (210, 310) formed with the central hole portions (211 and 311) and a plurality of the substrate formed in a distributed manner around the central hole portion so as to protrude from one of the two surfaces of the substrate. A plurality of second adhesion assisting devices (200, 300) integrally formed of synthetic resin so as to have surface side engagement pieces (220, 340),
The plurality of first adhesion assisting devices are arranged so that each thick annular support wall faces one mold frame (F) of both mold frames (F) that are installed facing each other. It is connected to a plurality of spacer bolts (150) distributed from the frame side and extending toward the other mold side, and each thick annular support wall is connected to the corresponding connector side via the one mold frame. By pressing each corresponding thin annular connecting wall while deforming it, outward from the outer peripheral part of the surface side of each corresponding connector so that each thick annular support wall surrounds the plurality of surface side engaging pieces Seated on an annular flange (115) extending radially toward
The plurality of second adhesion assisting devices are formed by hardening concrete ready to be driven through the plurality of spacer bolts and the plurality of first adhesion assisting devices between the two molds, and after the two molds are removed. Dispersed and disposed on the surface of the concrete body at a position different from the plurality of first adhesion assisting devices, and each of the central holes is fastened to the surface of the concrete body with screws.
The mortar wall is formed by applying raw mortar with a predetermined thickness to the surface of the concrete body via each of the plurality of first and second adhesion assisting devices and curing the mortar wall.
　このように構成した複数の第１接着補助器具及び複数の第２接着補助器具を備えて、複数の第１接着補助器具は、各厚肉環状支持壁にて、互いに対向して設置してなる両型枠の一方の型枠に対向するように、当該一方の型枠側から分散して他方の型枠側に向けて延出する複数のスペーサボルトに連結され、かつ、一方の型枠を介し各厚肉環状支持壁を各対応のコネクター側へ各対応の薄肉環状連結壁を変形させながら押圧することで、各厚肉環状支持壁にて、複数の面側係合片を包囲するように、各対応のコネクターの表面側外周部から外方に向け半径方向に延出する環状フランジに着座してなる。 A plurality of first adhesion assisting devices and a plurality of second adhesion assisting devices configured as described above are provided, and the plurality of first adhesion assisting devices are installed opposite to each other at each thick annular support wall. It is connected to a plurality of spacer bolts that are dispersed from the one mold side and extend toward the other mold side so as to face one of the two mold forms, and one mold is Each thick annular support wall is pressed against each corresponding connector side while deforming each corresponding thin annular connection wall, so that each thick annular support wall surrounds the plurality of surface side engagement pieces. Further, each connector is seated on an annular flange extending radially outward from the outer peripheral portion on the surface side of the corresponding connector.
　これにより、複数の第１接着補助器具の各々においては、厚肉環状支持壁が、環状フランジ及び一方の型枠と共に、密閉空間を構成して、当該密閉空間内に複数の面側係合片を閉じ込めるので、上述のように生コンクリートを両型枠の間に打ち込んでも、複数の面側係合片が当該生コンクリートから隔離されている。従って、当該生コンクリートが複数の面側係合片に達することがない。 Thereby, in each of the plurality of first adhesion assisting devices, the thick annular support wall constitutes a sealed space together with the annular flange and one mold, and a plurality of surface-side engagement pieces in the sealed space. Therefore, even if the ready-mixed concrete is driven between the two molds as described above, the plurality of surface-side engaging pieces are isolated from the ready-mixed concrete. Therefore, the ready-mixed concrete does not reach the plurality of surface side engaging pieces.
　また、厚肉環状支持壁は、薄肉環状連結壁とは異なり、一方の型枠による押圧によって変形することはないので、複数の面側係合片は、その原形状を、上述の密閉空間内にて、良好に維持し得る。 In addition, unlike the thin annular connection wall, the thick annular support wall is not deformed by pressing with one mold, so that the plurality of surface side engagement pieces have their original shapes in the above-described sealed space. It can be maintained well.
　従って、上述のように、生モルタルがコンクリート体の表面に複数の第１接着補助器具を介し塗布されることで、当該生モルタルは、各第１接着補助器具の複数の面側係合片に良好に係合し得る。このことは、各第１接着補助器具の複数の面側係合片は、生モルタルの硬化後に形成されるモルタル壁にその内部にてしっかりと係合し得ることを意味する。その結果、複数の第１接着補助器具は、その各複数の面側係合片でもって、モルタル壁のコンクリート体に対する接着を良好に補助し、モルタル壁のコンクリート体に対する接着力、即ちアンカー効果を良好に高め得る。 Therefore, as described above, the raw mortar is applied to the surface of the concrete body via the plurality of first adhesion assisting devices, so that the raw mortar is applied to the plurality of surface side engagement pieces of each first adhesion assisting device. It can engage well. This means that the plurality of face-side engagement pieces of each first bonding aid can securely engage within the mortar wall formed after the green mortar is cured. As a result, the plurality of first adhesion assisting devices favorably adhere the mortar wall to the concrete body with each of the plurality of surface side engagement pieces, and provide an adhesive force of the mortar wall to the concrete body, that is, an anchor effect. Can be improved well.
　また、複数の第１接着補助器具は、上述のように両型枠を除去した後も、各コネクターにて、対応の各スペーサボルトに連結したまま、取り外すことなく、そのまま、継続的に維持されるので、当該複数の第１接着補助器具の取外し作業や新たな取付け作業を繰り返す必要がないため、作業性を向上し得るのは勿論のこと、複数の第１接着補助器具の廃棄に起因するような環境汚染問題の発生をも未然に防止し得る。 In addition, after removing both molds as described above, the plurality of first adhesion assisting devices are continuously maintained as they are without being removed while being connected to the corresponding spacer bolts at each connector. Therefore, since it is not necessary to repeat the removal work and the new attachment work of the plurality of first adhesion assisting instruments, the workability can be improved, and it is caused by the disposal of the plurality of first adhesion assisting instruments. The occurrence of such environmental pollution problems can be prevented in advance.
　また、上述のように、コンクリート体が両型枠の間に打ち込まれる生コンクリートの硬化により形成された上で、両型枠が除去された後において、複数の第２接着補助器具が、コンクリート体の表面に複数の第１接着補助器具とは異なる位置にて分散して配設されるとともに、それぞれ、中央孔部にて、各ネジによりコンクリート体の表面に締着されている。 In addition, as described above, after the concrete body is formed by hardening of the ready-mixed concrete that is driven between the two molds, and after the two molds are removed, the plurality of second adhesion assisting tools are provided with the concrete body. Are distributed at different positions from the plurality of first adhesion assisting devices, and are fastened to the surface of the concrete body by screws at the central hole.
　従って、当該複数の第２接着補助器具は、各ネジによりコンクリート体の表面にしっかりと組み付けられている。このような状態で、生モルタルが上述のようにコンクリート体の表面に塗布されることで、当該生モルタルが、複数の第２接着補助器具の各々の複数の面側係合片に、複数の第１接着補助器具の各複数の面側係合片と同様に、しっかりと係合し得る。 Therefore, the plurality of second adhesion assisting devices are firmly assembled to the surface of the concrete body by the screws. In such a state, the raw mortar is applied to the surface of the concrete body as described above, so that the raw mortar is attached to each of the plurality of surface side engagement pieces of the plurality of second adhesion assisting devices. Similar to each of the plurality of surface-side engagement pieces of the first adhesion assisting device, it can be firmly engaged.
　これに伴い、生モルタルが硬化してモルタル壁として形成されることで、複数の第２接着補助器具の各々の複数の面側係合片は、モルタル壁に、その内部にて、複数の第１接着補助器具の各々の複数の面側係合片と同様にしっかりと係合し得る。その結果、複数の第２接着補助器具は、その各複数の面側係合片でもって、複数の第１接着補助器具と同様に、モルタル壁のコンクリート体に対する接着を良好に補助し、モルタル壁のコンクリート体に対する接着力、即ちアンカー効果を良好に高め得る。 Along with this, the raw mortar is hardened and formed as a mortar wall, so that the plurality of surface side engagement pieces of each of the plurality of second adhesion assisting devices are in contact with the mortar wall. The plurality of surface-side engaging pieces of each of the adhesion assisting devices can be firmly engaged as well. As a result, the plurality of second adhesion assisting devices, like the plurality of first adhesion assisting devices, favorably adhere the mortar wall to the concrete body with each of the plurality of surface side engagement pieces. It is possible to satisfactorily enhance the adhesion strength of the concrete body to the concrete body, that is, the anchor effect.
　ここで、複数の第１接着補助器具は、それぞれ、複数の面側係合片にて、コンクリート体の表面から突出するのみであり、複数の第２接着補助器具の各々の基板は、板状であるから、生モルタルの塗布厚さは、ほぼ、コンクリート体の表面に亘り、一様に維持し得るのは勿論のこと、可能な限り薄くすることができることから、生モルタルの塗布量の軽減に役立つ。 Here, each of the plurality of first adhesion assisting devices only protrudes from the surface of the concrete body with the plurality of surface-side engagement pieces, and each of the plurality of second adhesion assisting devices has a plate-like shape. Therefore, the coating thickness of raw mortar can be kept as uniform as possible over the surface of the concrete body, and can be made as thin as possible. To help.
　以上のように、複数の第１接着補助器具及び複数の第２接着補助器具が、コンクリート体とモルタル壁との間に分散して埋設されることで、各第１接着補助器具及び各第２接着補助器具が、ともに、各複数の面側係合片でもって、モルタル壁のコンクリート体に対するアンカー効果を相乗的に高め得る。このことは、複数の第１及び第２の接着補助器具による相乗的な接着補助のもと、モルタル壁が、コンクリート体から剥がれ落ちたりすることなく、長期に亘り、コンクリート体の表面に対する接着を良好に維持し得ることを意味する。 As described above, the plurality of first adhesion assisting devices and the plurality of second adhesion assisting devices are dispersed and embedded between the concrete body and the mortar wall, so that each first adhesion assisting device and each second adhesion assisting device are embedded. Both of the adhesion assisting devices can synergistically enhance the anchor effect of the mortar wall on the concrete body with each of the plurality of surface side engagement pieces. This means that the mortar wall can adhere to the surface of the concrete body for a long period of time without causing the mortar wall to peel off from the concrete body under the synergistic adhesion assistance by the plurality of first and second adhesion assisting devices. It means that it can be maintained well.
　また、本発明は、上述したモルタル用接着補助システムにおいて、
　複数のスペーサボルトは、上記一方の型枠側から矩形輪郭状に分散して上記他方の型枠側に向けて延出されており、
　複数の第１接着補助器具は、上記矩形輪郭状に分散して延出する複数のスペーサボルトに連結されて複数の第１接着補助器具群を構成してなり、
　複数の第２接着補助器具は、コンクリート体の表面に両型枠の除去後複数の第１接着補助器具群により形成される各矩形状輪郭（ＲＬ）の中央に配設されることを特徴とする。 Further, the present invention provides the above-described adhesion assist system for mortar,
The plurality of spacer bolts are distributed in a rectangular contour shape from the one mold side and extended toward the other mold side.
The plurality of first adhesion assisting devices are connected to the plurality of spacer bolts extending in a distributed manner in the rectangular outline to constitute a plurality of first adhesion assisting device groups,
The plurality of second adhesion assisting devices are arranged at the center of each rectangular outline (RL) formed by the plurality of first adhesion assisting device groups after removing both molds on the surface of the concrete body. To do.
　このように、複数の第１接着補助器具が、複数の第１接着補助器具群として配設され、かつ、複数の第２接着補助器具の各々が、複数の第１接着補助器具群の各矩形状輪郭の中央に配設されることで、矩形状輪郭ごとに、当該矩形状輪郭の４つの隅角部に配設される４個の第１接着補助器具が、当該矩形状輪郭の中央に配設される１個の第２接着補助器具とともに、バランスのよい接着補助力をモルタル壁に対し発揮し得る。その結果、モルタル壁は、その全体に亘り、バランスよく、上述のように配設してなる各複数の第１及び第２の接着補助器具による接着補助のもと、長期に亘り、コンクリート体の表面に対する接着を良好に維持し得る。 In this way, the plurality of first adhesion assisting devices are arranged as a plurality of first adhesion assisting device groups, and each of the plurality of second adhesion assisting devices is each rectangular of the plurality of first adhesion assisting device groups. By being arranged at the center of the shape outline, for each rectangular outline, four first bonding assisting devices arranged at the four corners of the rectangular outline are arranged at the center of the rectangular outline. Along with one second adhesion assisting device, a well-balanced adhesion assisting force can be exerted on the mortar wall. As a result, the mortar wall has a well-balanced overall mortar wall, and the concrete body is maintained over a long period of time with adhesion assistance by the plurality of first and second adhesion assisting devices arranged as described above. Good adhesion to the surface can be maintained.
　また、本発明は、上述したモルタル用接着補助システムにおいて、複数の第１接着補助器具群は、それぞれ、各第１接着補助器具にて、多数の糸状片（１４３）を厚肉環状支持壁内に延長するように当該厚肉環状支持壁の内面に一体的に形成してなることを特徴とする。 Further, according to the present invention, in the adhesion assist system for mortar described above, each of the plurality of first adhesion assist devices includes a plurality of thread-like pieces (143) in the thick annular support wall. It is characterized by being formed integrally with the inner surface of the thick annular support wall so as to extend.
　これにより、各第１接着補助器具は、複数の面側係合片だけでなく、多数の糸状片によって、生モルタルと係合するので、モルタル壁のコンクリート体に対するアンカー効果をより一層強化し得る。このことは、複数の第１接着補助器具及び複数の第２接着補助器具の双方によるモルタル壁に対する接着補助力がより一層向上し得ることを意味する。 Thereby, since each 1st adhesion auxiliary instrument engages with a raw mortar not only with a some surface side engagement piece but with many thread-like pieces, the anchor effect with respect to the concrete body of a mortar wall can be strengthened further. . This means that the adhesion assisting force on the mortar wall by both the plurality of first adhesion assisting devices and the plurality of second adhesion assisting devices can be further improved.

Here, the nut 160c presses one mold F toward the surface side of the spacer 110 in a screwed state with the corresponding spacer bolt 150 through the mold tension fitting 160a and the pair of thick end members 160b. Thus, screwing adjustment is performed with the corresponding formwork clamping bolt 160.
　これに伴い、環状支持壁１４０が、コネクター１１０の環状フランジ１１５に向けて押し込まれる。すると、環状連結壁１３０が上述のごとく変形し易いように形成されているため、環状支持壁１４０は、環状連結壁１３０を屈曲変形させながら、環状フランジ１１５の受承面１１５ａに当接するまで変位する。このとき、環状連結壁１３０は、反転して屈曲変形しながら、環状支持壁１４０の内周面とコネクター１１０の小径部１１０ｂの外周面との間に挟まれていく。 Along with this, the annular support wall 140 is pushed toward the annular flange 115 of the connector 110. Then, since the annular connecting wall 130 is formed so as to be easily deformed as described above, the annular support wall 140 is displaced until it abuts against the receiving surface 115a of the annular flange 115 while bending the annular connecting wall 130.

At this time, the annular connecting wall 130 is sandwiched between the inner peripheral surface of the annular support wall 140 and the outer peripheral surface of the small-diameter portion 110b of the connector 110 while being bent and deformed.
　そして、環状支持壁１４０がその下端部にて環状フランジ１１５の受承面１１５ａに当接すると、環状連結壁１３０は、環状支持壁１４０の内周面とコネクター１１０の小径部１１０ｂの外周面との間にて、楔状に変形し、環状支持壁１４０をコネクター１１０に対し固定状態に維持する。 When the annular support wall 140 comes into contact with the receiving surface 115a of the annular flange 115 at its lower end, the annular connection wall 130 is connected to the inner peripheral surface of the annular support wall 140 and the outer peripheral surface of the small-diameter portion 110b of the connector 110. In the meantime, the ring-shaped support wall 140 is fixed to the connector 110 in a wedge shape.
　然る後、環状支持壁１４０が、その内周面側にて環状連結壁１３０を屈曲変形させた状態で、環状フランジ１１５の受承面１１５ａ上に着座して支持される（図１５参照）。このため、環状連結壁１３０及び複数の面側係合片１２０が、環状支持壁１４０により包囲されて、コネクター１１０の小径部１１０ｂと一方の型枠Ｆとの間に密封される。 Thereafter, the annular support wall 140 is seated and supported on the receiving surface 115a of the annular flange 115 in a state where the annular connecting wall 130 is bent and deformed on the inner peripheral surface side (see FIG. 15). . Therefore, the annular connecting wall 130 and the plurality of surface side engagement pieces 120 are surrounded by the annular support wall 140 and sealed between the small diameter portion 110 b of the connector 110 and the one mold F.
　なお、一方の型枠Ｆを介するナット１６０ｃの第１接続補助器具１００に対する押圧力は、約２００（ｋｇｆ／ｃｍ２）、即ち、１９．６（ＭＰａ）に達するものの、この押圧力は、環状支持壁１４０により受け止められるため、各面側係合片１２０が押圧力でもって潰されることはない。 Note that the pressing force of the nut 160c through the one mold F against the first connection assisting device 100 reaches approximately 200 (kgf / cm 2 ), that is, 19.6 (MPa). Since it is received by the support wall 140, each surface side engagement piece 120 is not crushed by the pressing force.
　型枠締め付けボルト締着工程Ｓ３の処理後、生コンクリート打ち込み工程Ｓ４において、生コンクリートが両型枠Ｆの間に打ち込まれる。これに伴い、生コンクリートが、両型枠Ｆの間に流入する。なお、生コンクリートとは、いまだ硬化していないコンクリートをいう。 After the processing of the formwork tightening bolt fastening step S3, the ready-mixed concrete is driven between the two formwork F in the ready-mixed concrete placing step S4. Accordingly, ready-mixed concrete flows between both molds F. Note that ready-mixed concrete refers to concrete that has not yet hardened.
　このとき、左上側接着補助器具１００は、上述のごとく、環状連結壁１３０及び複数の面側係合片１２０にて、コネクター１１０の小径部１１０ｂと一方の型枠Ｆとの間に密封されているため、生コンクリートが環状支持壁１４０の内側に入り込むことはない。これにより、複数の面側係合片１２０は、生コンクリートから確実に隔離され得る。 At this time, as described above, the left upper adhesion assisting device 100 is sealed between the small-diameter portion 110b of the connector 110 and the one mold F by the annular connecting wall 130 and the plurality of surface-side engagement pieces 120. Therefore, the ready-mixed concrete does not enter the inside of the annular support wall 140. Thereby, the some surface side engaging piece 120 can be reliably isolated from ready-mixed concrete.
　上述のごとく、生コンクリートが両型枠Ｆ間に流入することにより、当該生コンクリートが，両型枠の間の空間領域のうち左上側接着補助器具１００を除く領域に充満することとなる。 As described above, when the ready-mixed concrete flows between the two molds F, the ready-mixed concrete fills the area excluding the left upper adhesion assisting device 100 in the space area between the two molds.
　然る後、次の生コンクリート硬化待ち工程Ｓ５において、両型枠Ｆ間に充満している生コンクリートが硬化するまで所定待ち時間の間待つ。このようにして生コンクリートが硬化すると、コンクリート壁１０ａが形成される。このとき、コンクリート壁１０ａには、左上側接着補助器具１００を収容してなる収容穴部１２が形成されている。 After that, in the next ready concrete hardening waiting step S5, it waits for a predetermined waiting time until ready concrete filled between both molds F hardens. When the ready-mixed concrete hardens in this way, a concrete wall 10a is formed. At this time, the concrete wall 10a is formed with an accommodation hole portion 12 for accommodating the upper left adhesion assisting device 100.
　次の型枠締め付けボルト取り外し工程Ｓ６において、ナット１６０ｃが対応型枠締め付けボルト１６０から離脱される。然る後、型枠緊張結金具１６０ａ及び一対の端太材１６０ｂが対応型枠締め付けボルト１６０から離脱されるとともに、対応型枠締め付けボルト１６０がコネクター１１０の表面側雌ネジ部分１１１ａから離脱される。 In the next mold clamping bolt removal step S6, the nut 160c is detached from the corresponding mold clamping bolt 160. Thereafter, the formwork tension fitting 160a and the pair of thick end members 160b are detached from the corresponding formwork clamping bolt 160, and the corresponding formwork fastening bolt 160 is detached from the front-side female thread portion 111a of the connector 110. .
　このとき、対応型枠締め付けボルト１６０を回動して離脱させることになるが、コネクター１１０の外周面に形成してなる各リブ１１６ａが、コンクリート壁１０ａの収容穴部１２の周壁部により回動不能に維持されているため、第１接着補助器具１００が、対応型枠締め付けボルト１６０の回動に付随して共回りすることはない。また、コネクター１１０の環状フランジ１１５が、コンクリート壁１０ａのうちの収容穴部１２の周壁部位内に保持されているため、第１接着補助器具１００が収容穴部１２から脱出することもない。 At this time, the corresponding formwork clamping bolt 160 is rotated and detached, but each rib 116a formed on the outer peripheral surface of the connector 110 is rotated by the peripheral wall portion of the accommodation hole portion 12 of the concrete wall 10a. Since it is maintained incapable, the first adhesion assisting device 100 does not rotate together with the rotation of the corresponding formwork clamping bolt 160. Further, since the annular flange 115 of the connector 110 is held in the peripheral wall portion of the accommodation hole 12 in the concrete wall 10 a, the first adhesion assisting device 100 does not escape from the accommodation hole 12.
　なお、以上のような工程の処理は、図１の４つの第１接着補助器具１００のうちの各残りの第１接着補助器具１００についても、同様になされる。 In addition, the process of the above processes is similarly performed about each remaining 1st adhesion auxiliary instrument 100 of the four 1st adhesion auxiliary instruments 100 of FIG.
　ついで、型枠取り外し工程Ｓ７において、両型枠Ｆが、コンクリート壁１０ａから取り外される。これに伴い、コンクリート壁１０ａが、図１６にて示すごとく、その収容穴部１２内に左上側接着補助器具１００を収容した状態で、両型枠Ｆから解放される。このとき、左上側接着補助器具１００は、コネクター１１０の裏面側雌ネジ部分１１１ｂにより、収容穴部１２内にて、その底壁部から突出するスペーサネジ１５０の一方の軸方向雄ネジ部により支持されている。 Next, in the mold removing step S7, both molds F are removed from the concrete wall 10a. Accordingly, the concrete wall 10a is released from both molds F in a state where the upper left adhesion assisting device 100 is accommodated in the accommodation hole 12 as shown in FIG. At this time, the left upper adhesion assisting device 100 is supported by the back surface side female thread portion 111b of the connector 110 by one axial male thread portion of the spacer screw 150 protruding from the bottom wall portion in the accommodation hole portion 12. ing.
　ついで、第２接着補助器具組み付け工程Ｓ８において、複数の第２接着補助器具２００のうちの上記中央側接着補助器具２００が、次のようにして、一方の型枠Ｆに組み付けられる。 Next, in the second adhesion assisting device assembling step S8, the center-side adhesion assisting device 200 among the plurality of second adhesion assisting devices 200 is assembled to one mold F as follows.
　即ち、中央側接着補助器具２００が、基板２１０にて、コンクリート壁１０ａの表面１１のうち第１矩形状輪郭ＲＬの中央に対する対応部位に設置される（図１及び図１７参照）。このとき、基板２１０は、その裏面にて、図１７にて示すごとく、複数の面側係合片２３０及び４個のフック２２０ａ～２２０ｄを外方に向け突出させるように、コンクリート壁１０ａの表面１１に設置される。 That is, the center side adhesion assisting device 200 is installed on the substrate 210 at a portion corresponding to the center of the first rectangular contour RL in the surface 11 of the concrete wall 10a (see FIGS. 1 and 17). At this time, as shown in FIG. 17, the substrate 210 has a surface on the back surface of the concrete wall 10a so that the plurality of surface side engaging pieces 230 and the four hooks 220a to 220d protrude outward. 11 is installed.
　このような設置状態において、図１８に示す座金ＷＳが、図１７にて示すごとく、基板２１０のうち中央孔部２１１を中心とする環状部位（以下、中央環状部位Ｐともいう）上に４個のフック２２０ａ～２２０ｄを介し設置される。 In such an installation state, as shown in FIG. 17, four washers WS shown in FIG. 18 are provided on the annular portion (hereinafter also referred to as the central annular portion P) centered on the central hole portion 211 of the substrate 210. Are installed through the hooks 220a to 220d.
　ここでは、座金ＷＳが、各フック２２０ａ～２２０ｄをその弾力に抗して折れ曲がり部２２２にて押し広げるようにして、中央環状部位Ｐ上に設置される。このため、座金ＷＳが、各フック２２０ａ～２２０ｄの内側にて当該各フック２２０ａ～２２０ｄの折れ曲がり部２２２と基板２１０の環状中央部位Ｐとの間に挟持される。 Here, the washer WS is installed on the central annular portion P so as to push the hooks 220a to 220d at the bent portion 222 against the elasticity. For this reason, the washer WS is sandwiched between the bent portions 222 of the hooks 220a to 220d and the annular central portion P of the substrate 210 inside the hooks 220a to 220d.
　本第１実施形態において、座金ＷＳは、平座金として、例えば、ステンレススチールでもって環状に形成されており、当該座金ＷＳの厚さＺ、内径Ｒｉ及び外径Ｒｏは、それぞれ、Ｚ＝０．７（ｍｍ）、Ｒｉ＝６（ｍｍ）及びＲｏ＝１３（ｍｍ）に設定されている。なお、中央環状部位Ｐは、各フック２２０ａ～２２０ｄの立ち上がり部２２１の基板２１０からの延出基端部の内側（中央孔部２１１側）において基板２１０に形成される環状領域をいう。 In the first embodiment, the washer WS is formed as a flat washer, for example, in an annular shape with stainless steel, and the thickness Z, the inner diameter Ri, and the outer diameter Ro of the washer WS are Z = 0. 7 (mm), Ri = 6 (mm), and Ro = 13 (mm). The central annular portion P refers to an annular region formed in the substrate 210 on the inner side (on the central hole 211 side) of the base end portion extending from the substrate 210 of the rising portion 221 of each hook 220a to 220d.
　上述のように座金ＷＳを挟持した後、コンクリートネジＳＣが、図１７にて示すごとく、その首下部にて、座金ＷＳの中空部及び基板２１０の中央孔部２１１を通してコンクリート壁１０ａに締着される。 After sandwiching the washer WS as described above, the concrete screw SC is fastened to the concrete wall 10a through the hollow portion of the washer WS and the central hole portion 211 of the substrate 210 at the bottom of the neck as shown in FIG. The
　この締着は、電気工具（図示しない）によりコンクリート壁１０ａに座金ＷＳの中空部及び基板２１０の中央孔部２１１を通して下孔部を形成した後に、コンクリートネジＳＣをその首下部にて座金ＷＳの中空部及び基板２１０の中央孔部２１１を通して上記下孔部に締着することで行われる。 This fastening is performed by forming a hollow portion of the washer WS in the concrete wall 10a and a lower hole portion through the central hole portion 211 of the substrate 210 with an electric tool (not shown), and then inserting a concrete screw SC at the lower portion of the washer WS. This is done by fastening to the lower hole portion through the hollow portion and the central hole portion 211 of the substrate 210.
　このような締着状態においては、座金ＷＳの内径Ｒｉが基板２１０の中央孔部２１１の内径Ｖと同一であることから、コンクリートネジＳＣは、その頭部にて、座金ＷＳを基板２１０の中央孔部２１１の外周部上にしっかりと保持し得る。従って、基板２１０は、座金ＷＳ及びコンクリートネジＳＣによってコンクリート壁１０ａに安定状態にてしっかりと組み付けられ得る。 In such a fastened state, since the inner diameter Ri of the washer WS is the same as the inner diameter V of the central hole 211 of the substrate 210, the concrete screw SC holds the washer WS at the center of the substrate 210 at its head. It can be firmly held on the outer periphery of the hole 211. Accordingly, the substrate 210 can be securely assembled to the concrete wall 10a in a stable state by the washer WS and the concrete screw SC.
　以上のようにして４個の第１接着補助器具１００及び第２接着補助器具２００（中央側接着補助器具２００）のコンクリート壁１０ａに対する組み付けが終了すると、次の生モルタル塗布工程Ｓ９において、生モルタルが、図２及び図３にて示すごとく、所定の厚さにて、コンクリート壁１０ａの表面１１の全体に亘り塗布される。なお、生モルタルとは、未だ硬化していないモルタルをいう。 When the assembly of the four first adhesion assisting devices 100 and the second adhesion assisting device 200 (center side adhesion assisting device 200) to the concrete wall 10a is completed as described above, in the next raw mortar application step S9, the raw mortar As shown in FIG.2 and FIG.3, it is apply | coated over the whole surface 11 of the concrete wall 10a by predetermined thickness. In addition, raw mortar means mortar which has not yet hardened.
　このとき、当該塗布は、４個の第１接着補助器具１００及び第２接着補助器具２００をコンクリート壁１０ａの表面上にて覆うようになされる。従って、各第１接着補助器具１００は、コンクリート壁１０ａの収容穴部１２内に収容された状態にて生モルタルにより当該コンクリート壁１０ａに埋設されるとともに、第２接着補助器具２００が、コンクリート壁１０ａの表面１１上にて生モルタルにより埋設されることとなる。 At this time, the application is performed so as to cover the four first adhesion assisting devices 100 and the second adhesion assisting device 200 on the surface of the concrete wall 10a. Accordingly, each first adhesion assisting device 100 is embedded in the concrete wall 10a with raw mortar while being accommodated in the accommodation hole 12 of the concrete wall 10a, and the second adhesion assisting device 200 is connected to the concrete wall 10a. It will be buried with raw mortar on the surface 11 of 10a.
　これに伴い、生モルタルは、各第１接着補助器具１００の環状支持壁１４０の内部に浸入する。ついで、このように浸入した生モルタルは、さらに、複数の面側係合片１２０を介しコネクター１１０の表面に向けて浸入するとともに、環状溝部１１２の内部及び雌ネジ孔部１１１の表面側雌ネジ孔部分１１１ａの内部に浸入する。 Accordingly, the raw mortar enters the inside of the annular support wall 140 of each first adhesion assisting device 100. Subsequently, the raw mortar that has entered in this way further enters the surface of the connector 110 via the plurality of surface side engagement pieces 120, and the inside of the annular groove 112 and the surface side female screw of the female screw hole 111. It enters the inside of the hole portion 111a.
　ここで、上述のように複数の面側係合片１２０を介しコネクター１１０の表面に向けて浸入する生モルタルは、複数の面側係合片１２０の各々の間を通りコネクター１１０の表面に達する。 Here, the raw mortar that penetrates toward the surface of the connector 110 via the plurality of surface-side engagement pieces 120 as described above passes between each of the plurality of surface-side engagement pieces 120 and reaches the surface of the connector 110. .
　また、このようにコネクター１１０の表面に達する生コンクリートは、コネクター１１０の表面に形成した各湾曲面部１１４上にも達する。このことは、生コンクリートが，互いに対向する面側係合片１２０と湾曲面部１１４との間にも行き亘ることを意味する。従って、複数の面側係合片１２０とコネクター１１０の表面との間に浸入する生モルタルの量は、コネクター１１０の表面に複数の湾曲面部１１４を形成したことで、増大する。 Further, the ready-mixed concrete that reaches the surface of the connector 110 in this way also reaches each curved surface portion 114 formed on the surface of the connector 110. This means that the ready-mixed concrete extends between the surface-side engaging pieces 120 and the curved surface portion 114 that face each other. Therefore, the amount of raw mortar that penetrates between the plurality of surface side engagement pieces 120 and the surface of the connector 110 is increased by forming the plurality of curved surface portions 114 on the surface of the connector 110.
　また、上述のように環状支持壁１４０内に浸入した生モルタルは、環状溝部１１２の内部及び雌ネジ孔部１１１の表面側雌ネジ孔部分１１１ａの内部にも浸入する。 Further, the raw mortar that has entered the annular support wall 140 as described above also enters the inside of the annular groove 112 and the inside of the female screw hole portion 111 a of the female screw hole 111.
　また、第２接着補助器具２００においては、上述のように生モルタルが塗布されると、当該生モルタルは、複数の面側係合片２３０を介し基板２１０の表面に達する。ここで、このように複数の面側係合片２３０を介し基板２１０の表面に達する生モルタルは、互いに隣り合う各両面側係合片２３０の間を通り基板２１０の複数の外側開孔部２１３ａ～２１３ｊの各内部に行き亘る。 Further, in the second adhesion assisting device 200, when raw mortar is applied as described above, the raw mortar reaches the surface of the substrate 210 via the plurality of surface-side engagement pieces 230. Here, the raw mortar that reaches the surface of the substrate 210 through the plurality of surface-side engagement pieces 230 in this way passes between the two surface-side engagement pieces 230 adjacent to each other, and the plurality of outer opening portions 213a of the substrate 210. ˜213j is reached inside.
　上述のような生モルタル塗布工程Ｓ９の後、次の生モルタル硬化待ち工程Ｓ１０において、上述のようにコンクリート壁１０ａの表面１１に塗布した生モルタルが硬化するまで所定時間の間待つ。これに伴い、当該生モルタルが硬化すると、モルタル壁Ｍがコンクリート壁１０ａの表面１１上に形成される。 After the raw mortar coating step S9 as described above, in the next raw mortar curing waiting step S10, the process waits for a predetermined time until the raw mortar applied to the surface 11 of the concrete wall 10a is cured as described above. Accordingly, when the raw mortar is cured, a mortar wall M is formed on the surface 11 of the concrete wall 10a.
　以上説明した通り、本第１実施形態では、接着補助システムが、上述のように構成した複数の第１接着補助器具１００及び複数の第２接着補助器具２００を備える。ここで、複数の第１接着補助器具１００が、各環状支持壁１４０にて両型枠Ｆの一方の型枠に対向するように、当該一方の型枠側から他方の型枠側に向けて延出する複数のスペーサボルト１５０に連結される。また、複数の第１接着補助器具１００が、各環状支持壁１４０にて、各対応の環状連結壁１３０を変形させながら当該一方の型枠を介し各対応のコネクター１１０側へ押圧される。これに伴い、複数の第１接着補助器具１００が、複数の面側係合片１２０を包囲するように、各対応のコネクター１１０の表面側外周部から外方に向け半径方向に延出する環状フランジ１１５に着座する。 As described above, in the first embodiment, the adhesion assisting system includes the plurality of first adhesion assisting instruments 100 and the plurality of second adhesion assisting instruments 200 configured as described above. Here, the plurality of first adhesion assisting devices 100 are directed from the one mold side to the other form side so that each annular support wall 140 faces one of the two form frames F. It is connected to a plurality of spacer bolts 150 that extend. Further, the plurality of first adhesion assisting devices 100 are pressed by the respective annular support walls 140 toward the corresponding connectors 110 through the one mold form while deforming the corresponding annular connecting walls 130. Accordingly, the plurality of first adhesion assisting devices 100 extend in the radial direction outward from the outer peripheral portions of the corresponding connectors 110 so as to surround the plurality of surface-side engagement pieces 120. It sits on the flange 115.
　これにより、複数の第１接着補助器具１００の各々においては、環状支持壁１４０が、環状フランジ１１５及び一方の型枠と共に、密閉空間を構成して、当該密閉空間内に複数の面側係合片１２０を閉じ込めるので、上述のように生コンクリートを両型枠Ｆの間に打ち込んでも、複数の面側係合片１２０が当該生コンクリートから隔離されている。従って、当該生コンクリートが複数の面側係合片１２０に達することがない。 Thereby, in each of the plurality of first adhesion assisting devices 100, the annular support wall 140 forms a sealed space together with the annular flange 115 and one mold, and a plurality of surface side engagements are performed in the sealed space. Since the piece 120 is confined, even if the ready-mixed concrete is driven between the two mold frames F as described above, the plurality of surface side engaging pieces 120 are isolated from the ready-made concrete. Therefore, the ready-mixed concrete does not reach the plurality of surface side engagement pieces 120.
　また、環状支持壁１４０は、環状連結壁１３０とは異なり、一方の型枠による押圧によって変形することはないので、複数の面側係合片１２０は、その原形状を、上述の密閉空間内にて、良好に維持し得る。 In addition, unlike the annular connecting wall 130, the annular support wall 140 is not deformed by pressing with one mold, so that the plurality of surface side engagement pieces 120 have their original shapes in the above-described sealed space. It can be maintained well.
　従って、上述のように、生モルタルがコンクリート壁１０ａの表面１１に複数の第１接着補助器具１００を介し塗布されることで、当該生モルタルは、各第１接着補助器具１００の複数の面側係合片１２０に良好に係合し得る。このことは、各第１接着補助器具１００の複数の面側係合片１２０は、生モルタルの硬化後に形成されるモルタル壁Ｍにその内部にてしっかりと係合し得ることを意味する。 Accordingly, as described above, the raw mortar is applied to the surface 11 of the concrete wall 10a via the plurality of first adhesion assisting devices 100, so that the raw mortar is a plurality of surface sides of each first adhesion assisting device 100. The engaging piece 120 can be satisfactorily engaged. This means that the plurality of surface-side engaging pieces 120 of each first adhesion assisting device 100 can firmly engage with the mortar wall M formed after the green mortar is cured.
　ここで、第１接着補助器具１００毎に、複数の面側係合片１２０或いは左右上下の各側係合片群１２０ａ、１２０ｂは、それぞれ、基板１１０の表面においてその左右方向中心線及び上下方向中心線の双方に対し対称的に設けられているため、各面側係合片１２０或いは各側係合片群１２０ａ、１２０ｂによるモルタル壁Ｍに対する接着補助力は、コネクター１１０の表面の全体に亘り均一に発生され得る。 Here, for each first adhesion assisting device 100, the plurality of surface-side engagement pieces 120 or the left and right and upper and lower side engagement piece groups 120 a and 120 b respectively have their left and right center lines and vertical directions on the surface of the substrate 110. Since it is provided symmetrically with respect to both of the center lines, the adhesion assisting force on the mortar wall M by each surface side engagement piece 120 or each side engagement piece group 120a, 120b extends over the entire surface of the connector 110. It can be generated uniformly.
　その結果、複数の第１接着補助器具１００は、その各複数の面側係合片１２０でもって、モルタル壁Ｍのコンクリート壁１０ａに対する接着を良好に補助し、モルタル壁Ｍのコンクリート壁１０ａに対する接着力（アンカー効果）を良好に高め得る。 As a result, the plurality of first adhesion assisting devices 100 favorably assist the adhesion of the mortar wall M to the concrete wall 10a with the plurality of surface side engagement pieces 120, and adhere the mortar wall M to the concrete wall 10a. The force (anchor effect) can be improved satisfactorily.
　また、複数の第１接着補助器具１００は、上述のように両型枠Ｆを取り外すことで除去した後も、各コネクター１１０にて、対応の各スペーサボルト１５０に連結したまま、取り外すことなく、そのまま、継続的に維持される。従って、当該複数の第１接着補助器具１００の取外し作業や新たな取付け作業を繰り返す必要がないため、作業性を向上し得るのは勿論のこと、複数の第１接着補助器具１００の廃棄に起因するような環境汚染問題の発生をも未然に防止し得る。 In addition, even after the plurality of first adhesion assisting devices 100 are removed by removing both molds F as described above, each connector 110 remains connected to the corresponding spacer bolt 150 without being removed. It is continuously maintained as it is. Accordingly, since it is not necessary to repeat the removal work and the new attachment work of the plurality of first adhesion assisting devices 100, workability can be improved, as well as due to the disposal of the plurality of first adhesion assisting devices 100. It is possible to prevent the occurrence of environmental pollution problems.
　また、上述のように、コンクリート壁１０ａが、両型枠Ｆの間に打ち込まれる生コンクリートの硬化により形成された上で、両型枠Ｆが、除去された後において、複数の第２接着補助器具２００が、コンクリート壁１０ａの表面１１に複数の第１接着補助器具１００とは異なる位置（矩形状輪郭ＲＬの中央部）にて分散して配設されるとともに、それぞれ、中央孔部２１１にて、各ネジＳＣによりコンクリート壁１０ａの表面１１に締着されている。 In addition, as described above, after the concrete wall 10a is formed by hardening of the ready-mixed concrete that is driven between the two molds F, after the two molds F are removed, a plurality of second adhesion assists are performed. The appliances 200 are arranged and distributed on the surface 11 of the concrete wall 10a at positions different from the plurality of first adhesion assisting appliances 100 (central portion of the rectangular outline RL), and are respectively provided in the central hole portions 211. The screws SC are fastened to the surface 11 of the concrete wall 10a.
　従って、当該複数の第２接着補助器具２００は、各ネジＳＣによりコンクリート壁１０ａの表面にしっかりと組み付けられている。このような状態で、生モルタルが上述のようにコンクリート壁１０ａの表面１１に塗布されることで、当該生モルタルが、複数の第２接着補助器具２００の各々の複数の面側係合片２３０に、複数の第１接着補助器具１００の各複数の面側係合片と同様に、しっかりと係合し得る。 Therefore, the plurality of second adhesion assisting devices 200 are firmly assembled to the surface of the concrete wall 10a by the screws SC. In such a state, the raw mortar is applied to the surface 11 of the concrete wall 10a as described above, so that the raw mortar has a plurality of surface side engagement pieces 230 of each of the plurality of second adhesion assisting devices 200. In addition, as with the plurality of surface-side engagement pieces of the plurality of first adhesion assisting devices 100, they can be firmly engaged.
　これに伴い、生モルタルが硬化してモルタル壁として形成されることで、複数の第２接着補助器具２００の各々の複数の面側係合片２３０は、モルタル壁に、その内部にて、複数の第１接着補助器具１００の各々の複数の面側係合片１２０と同様に、しっかりと係合し得る。 Accordingly, the raw mortar is cured and formed as a mortar wall, so that the plurality of surface-side engagement pieces 230 of each of the plurality of second adhesion assisting devices 200 are arranged on the mortar wall. Similarly to the plurality of surface-side engagement pieces 120 of each of the first adhesion assisting devices 100, the first adhesion assisting device 100 can be firmly engaged.
　ここで、第２接着補助器具２００毎に、複数の面側係合片２３０或いは左右上下の各側係合片群２３０ａ、２３０ｂは、それぞれ、基板２１０の表面において左右方向中心線Ｘ及び上下方向中心線Ｙの双方に対し対称的に設けられているため、各面側係合片２３０或いは左右上下の各側係合片群２３０ａ、２３０ｂによるモルタル壁Ｍに対する接着補助力は、基板２１０の表面の全体に亘り均一に発生され得る。 Here, for each second adhesion assisting device 200, the plurality of surface-side engaging pieces 230 or the left and right and upper and lower side engaging piece groups 230a and 230b are respectively arranged on the surface of the substrate 210 in the left-right direction center line X and the up-down direction Since it is provided symmetrically with respect to both of the center lines Y, the adhesion assisting force to the mortar wall M by each surface side engagement piece 230 or each of the left and right and upper and lower side engagement piece groups 230a and 230b is the surface of the substrate 210. Can be generated uniformly throughout.
　その結果、複数の第２接着補助器具２００は、その各複数の面側係合片２３０でもって、複数の第１接着補助器具１００と同様に、モルタル壁Ｍのコンクリート壁１０ａに対する接着を良好に補助し、モルタル壁Ｍのコンクリート壁１０ａに対する接着力、即ちアンカー効果を良好に高め得る。 As a result, the plurality of second adhesion assisting devices 200 can satisfactorily adhere the mortar wall M to the concrete wall 10a with the plurality of surface-side engagement pieces 230, similarly to the plurality of first adhesion assisting devices 100. It can assist, and can improve the adhesive force of the mortar wall M to the concrete wall 10a, that is, the anchor effect.
　ここで、複数の第１接着補助器具１００は、それぞれ、複数の面側係合片１２０にて、コンクリート壁１０ａの表面１１から突出するのみであり、複数の第２接着補助器具２００の各々の基板２１０は、板状であるから、生モルタルの塗布厚さは、ほぼ、コンクリート壁１０ａの表面に亘り、一様に維持し得るのは勿論のこと、可能な限り薄くすることができることから、生モルタルの塗布量の軽減に役立つ。 Here, each of the plurality of first adhesion assisting devices 100 only protrudes from the surface 11 of the concrete wall 10a at each of the plurality of surface-side engagement pieces 120. Since the substrate 210 is plate-shaped, the coating thickness of the raw mortar can be maintained as uniform over the surface of the concrete wall 10a, and can be made as thin as possible. Helps reduce the amount of raw mortar applied.
　また、第２接着補助器具２００は、第１接着補助器具１００の構成とは異なり、単なる板状の基板２１０に複数の面側係合片２３０及び４つのフック２２０ａ～２０ｄを形成した構成であることから、当該第２接着補助器具２００は、第１接着補助器具１００に比べてより一層簡単な構成にて形成することができる。 Further, unlike the configuration of the first adhesion assisting device 100, the second adhesion assisting device 200 has a configuration in which a plurality of surface side engagement pieces 230 and four hooks 220a to 20d are formed on a simple plate-like substrate 210. For this reason, the second adhesion assisting device 200 can be formed with a simpler configuration than the first adhesion assisting device 100.
　以上のように、複数の第１接着補助器具１００及び複数の第２接着補助器具２００が、コンクリート壁１０ａとモルタル壁Ｍとの間に格子状に分散して埋設されることで、各第１接着補助器具１００及び各第２接着補助器具２００が、ともに、各複数の面側係合片でもって、モルタル壁Ｍのコンクリート壁１０ａに対するアンカー効果を相乗的に高め得る。このことは、複数の第１及び第２の接着補助器具１００、２００による相乗的な接着補助のもと、モルタル壁Ｍが、コンクリート壁１０ａから剥がれ落ちたりすることなく、長期に亘り、コンクリート壁１０ａの表面１１に対する接着を良好に維持し得ることを意味する。

This is because the mortar wall M is not peeled off from the concrete wall 10a under the synergistic adhesion assistance by the plurality of first and second adhesion assisting devices 100, 200 for a long time. It means that adhesion to the surface 11 of 10a can be maintained well.

　以上のようにして第２接着補助器具２００Ａ（中央側接着補助器具２００Ａ）及び上記第１実施形態にて述べた４個の第１接着補助器具１００のコンクリート壁１０ａに対する組み付けが終了すると、次の生モルタル塗布工程Ｓ９において、生モルタルが、図３６にて示すごとく、上記第１実施形態と同様に、コンクリート壁１０ａの表面１１の全体に亘り塗布される。 When the assembly of the second adhesion assisting device 200A (center side adhesion assisting device 200A) and the four first adhesion assisting devices 100 described in the first embodiment to the concrete wall 10a is completed as described above, In the raw mortar application step S9, the raw mortar is applied over the entire surface 11 of the concrete wall 10a, as in the first embodiment, as shown in FIG.
　従って、上記第１実施形態にて述べた１接着補助器具１００は、コンクリート壁１０ａの収容穴部１２内に収容された状態にて生モルタルにより当該コンクリート壁１０ａに埋設されるとともに、第２接着補助器具２００Ａが、コンクリート壁１０ａの表面１１上にて生モルタルにより埋設される。 Therefore, the 1 adhesion auxiliary instrument 100 described in the first embodiment is embedded in the concrete wall 10a with raw mortar while being accommodated in the accommodation hole 12 of the concrete wall 10a, and the second adhesion. The auxiliary tool 200A is embedded with raw mortar on the surface 11 of the concrete wall 10a.
　これに伴い、生モルタルが、上記第１実施形態にて述べたと同様に、第１接着補助器具１００内に浸入するとともに、第２接着補助器具２００Ａにおいて、複数の内側糸状片２６０ｃ、複数の外側糸状片２６０ｄ、複数の外周側係合片２５０及び複数の面側係合片２３０を介し基板２１０の表面に達する。 Accordingly, raw mortar penetrates into the first adhesion assisting device 100 as described in the first embodiment, and in the second adhesion assisting device 200A, the plurality of inner thread-like pieces 260c and the plurality of outer threads are disposed. It reaches the surface of the substrate 210 via the thread-like piece 260d, the plurality of outer peripheral side engaging pieces 250 and the plurality of surface side engaging pieces 230.
　ここで、このように複数の面側係合片２３０を介し基板２１０の表面に達する生モルタルは、上記第１実施形態にて述べたと同様に、基板２１０の複数の外側開孔部３１３ａ～３１３ｋ、３１３ｎの各内部に行き亘る。 Here, the raw mortar that reaches the surface of the substrate 210 through the plurality of surface-side engagement pieces 230 in this manner is the plurality of outer opening portions 313a to 313k of the substrate 210 as described in the first embodiment. 313n.
　また、上述のように生モルタルが複数の外周側係合片２５０を介し基板２１０の表面に達する過程において、当該生モルタルは、各外周側係合片２５０の外周面にしっかりと係合する。このとき、各外周側係合片２５０において、腕部２５１が脚部２５２の延出端部からＬ字状に屈曲するように形成されているため、当該生モルタルは、各外周側係合片２５０の屈曲部にもしっかりと係合する。 In the process where the raw mortar reaches the surface of the substrate 210 via the plurality of outer peripheral engagement pieces 250 as described above, the raw mortar firmly engages with the outer peripheral surface of each outer peripheral engagement piece 250. At this time, in each outer peripheral side engagement piece 250, since the arm part 251 is formed so that it may be bent in an L shape from the extension end part of the leg part 252, the said raw mortar is each outer peripheral side engagement piece. It firmly engages with the 250 bends.
　また、上述のように生モルタルが複数の内側糸状片２６０ｃ及び複数の外側糸状片２６０ｄを介し基板２１０の表面に達する過程において、当該生モルタルは、複数の内側糸状片２６０ｃ及び複数の外側糸状片２６０ｄの各外周面にしっかりと係合する。しかも、各内側糸状片２６０ｃの延出端部及び各外側糸状片２６０ｄの延出端部は、上述のごとく、Ｌ字状に屈曲しているから、生モルタルは、各内側糸状片２６０ｃ及び各外側糸状片２６０ｄの延出端部に対ししっかりと係合する。 Further, as described above, in the process where the raw mortar reaches the surface of the substrate 210 via the plurality of inner thread-like pieces 260c and the plurality of outer thread-like pieces 260d, the raw mortar includes the plurality of inner thread-like pieces 260c and the plurality of outer thread-like pieces. It firmly engages each outer peripheral surface of 260d. Moreover, since the extending end portion of each inner thread-like piece 260c and the extending end portion of each outer thread-like piece 260d are bent in an L shape as described above, the raw mortar is composed of each inner thread-like piece 260c and each of the inner thread-like pieces 260c. The outer thread-like piece 260d is firmly engaged with the extended end portion.
　上述のような生モルタル塗布工程Ｓ９の後、次の生モルタル硬化待ち工程Ｓ１０において、上述のようにコンクリート壁１０ａの表面１１に塗布した生モルタルが硬化すると、モルタル壁Ｍがコンクリート壁１０ａの表面１１上に形成される。 After the raw mortar application step S9 as described above, when the raw mortar applied to the surface 11 of the concrete wall 10a is cured as described above in the next raw mortar hardening waiting step S10, the mortar wall M becomes the surface of the concrete wall 10a. 11 is formed.
　以上説明したように、本第６実施形態によれば、各第２接着補助器具２００Ａは、上記第１実施形態にて説明した各第２接着補助器具２００とは異なり、複数の面側係合片２３０に加えて、複数の外周側係合片２５０を上述した構成でもって備えている。 As described above, according to the sixth embodiment, each second adhesion assisting device 200A is different from each second adhesion assisting device 200 described in the first embodiment, and has a plurality of surface side engagements. In addition to the piece 230, a plurality of outer peripheral engagement pieces 250 are provided with the above-described configuration.
　しかも、環状部材ＷＳ１が、複数の内側糸状片２６０ｃ及び複数の糸状片２６０ｄを有することで、当該複数の内側糸状片２６０ｃ及び複数の糸状片２６０ｄでもって、生モルタルとしっかりと係合し得る。 In addition, since the annular member WS1 includes the plurality of inner thread-like pieces 260c and the plurality of thread-like pieces 260d, the plurality of inner thread-like pieces 260c and the plurality of thread-like pieces 260d can be firmly engaged with the raw mortar.
　このため、生モルタルが硬化してモルタル壁Ｍとなったとき、当該モルタル用接着補助器具２００Ａは、複数の面側係合片２３０だけでなく、複数の外周側係合片２５０並びに環状部材ＷＳ１の複数の内側糸状片２６０ｃ及び複数の外側糸状片２６０ｄによっても、モルタル壁Ｍにその内部にてしっかりと係合する。 For this reason, when the raw mortar hardens to become the mortar wall M, the mortar adhesion assisting device 200A includes not only the plurality of surface side engagement pieces 230 but also the plurality of outer peripheral side engagement pieces 250 and the annular member WS1. The plurality of inner thread-like pieces 260c and the plurality of outer thread-like pieces 260d also firmly engage with the mortar wall M inside thereof.
　従って、当該モルタル用接着補助器具２００Ａは、基板２１０から突出する複数の面側係合片２３０だけでなく、複数の外周側係合片２５０並びに環状部材ＷＳ１の複数の内側糸状片２６０ｃ及び複数の外側糸状片２６０ｄによっても、モルタル壁Ｍをコンクリート壁１０ａの表面１１に支持し得る。これにより、モルタル用接着補助器具２００Ａによるモルタル壁Ｍのコンクリート壁１０ａに対する接着補助力が、より一層強化され得る。 Therefore, the mortar adhesion assisting device 200A includes not only the plurality of surface side engagement pieces 230 protruding from the substrate 210 but also the plurality of outer peripheral side engagement pieces 250, the plurality of inner thread pieces 260c of the annular member WS1, and the plurality of pieces. The outer thread-like piece 260d can also support the mortar wall M on the surface 11 of the concrete wall 10a. Thereby, the adhesion auxiliary force with respect to the concrete wall 10a of the mortar wall M by the adhesion auxiliary instrument 200A for mortar can be further strengthened.
　ここで、第２接着補助器具２００Ａ毎に、複数の面側係合片２３０は、複数の外周側係合片２５０とともに、それぞれ、基板２１０の表面において左右方向中心線及び上下方向中心線の双方に対し対称的に設けられているため、各面側係合片２３０によるモルタル壁Ｍに対する接着補助力は、基板２１０の表面の全体に亘り均一に発揮され得る。また、このようなことは、環状部材ＷＳ１の複数の内側糸状片２６０ｃ及び複数の外側糸状片２６０ｄも、同様に基板２１０の表面において左右方向中心線及び上下方向中心線の双方に対し対称的に位置するように設けられていることで同様に達成され得る。 Here, for each second adhesion assisting device 200A, the plurality of surface-side engaging pieces 230, together with the plurality of outer peripheral-side engaging pieces 250, are both left and right centerlines and vertical centerlines on the surface of the substrate 210. Therefore, the adhesion assisting force on the mortar wall M by each surface side engagement piece 230 can be uniformly exerted over the entire surface of the substrate 210. This also means that the plurality of inner thread-like pieces 260c and the plurality of outer thread-like pieces 260d of the annular member WS1 are similarly symmetrical with respect to both the left-right direction center line and the up-down direction center line on the surface of the substrate 210. It can be similarly achieved by being provided to be located.
　その結果、本第６実施形態では、接着補助システムによる接着補助のもとにモルタル壁Ｍのコンクリート壁１０ａに対する接着力（アンカー効果）が、安定的により一層強化され得る。このことは、モルタル壁Ｍのコンクリート壁１０ａからの脱落が、長期に亘り、より一層良好に防止され得ることを意味する。 As a result, in the sixth embodiment, the adhesion force (anchor effect) of the mortar wall M to the concrete wall 10a can be further strengthened stably with the aid of adhesion by the adhesion assistance system. This means that the falling of the mortar wall M from the concrete wall 10a can be prevented even better over a long period of time.
　また、本第６実施形態では、環状部材ＷＳ１が、上記第１実施形態にて述べた環状部材ＷＳ１とは異なり、基板２１０と同様の形成材料（樹脂材料）でもって、上記構成を有するように一体成形により形成されている。このため、環状部材ＷＳ１が、生モルタルと良好に係合するに要する形状に自由に設計され得る。
