Description
本発明は、例えばコンクリート構造物や壁等に発生したクラック等の補修対象に流動性補修材を注入するための流動性補修材注入器に関するものである。 The present invention relates to a fluidity repair material injector for injecting a fluidity repair material into a repair target such as a crack generated in a concrete structure or a wall.
コンクリート構造物等において内部まで進展したクラックを補修する場合、接着剤等の流動性補修材を外表面のクラック開口から内部まで行き渡らせるには、流動性補修材に所定の圧力をかけて注入する必要がある。 When repairing cracks that have extended to the inside of a concrete structure, etc., in order to spread the fluid repair material such as adhesive from the crack opening on the outer surface to the inside, a predetermined pressure is applied to the fluid repair material. There is a need.
本願発明者は、このような用途に用いられ特許文献１に示されるような注入器を提案している。この注入器は、先端が補修対象であるクラックの開口を塞ぐように取り付けられ、基端が接着剤の供給源であるグリスガン等に接続される筒状の注入機構と、前記注入機構から分岐させて設けられ、接着剤の注入時に接着剤の一部が流入して内部の気体が圧縮されるように構成された蓄圧機構とを備えている。さらに前記蓄圧機構は、中空筒の先端部に蓋体が嵌めこまれ、前記蓋体の一部が前記中空容器の内部に突出した状態で取り付けられるように構成されている。このようにして、接着剤が前記中空容器内へ流入する前に内部の気体を予め圧縮しておくことができ、接着剤がクラック側へ押される圧力を大きくして、内部まで行きわたらせることができる。 The inventor of the present application has proposed an injector used for such an application and as shown in Patent Document 1. This injector is attached so that the tip closes the opening of the crack to be repaired, and the base end is branched from the injection mechanism and a tubular injection mechanism connected to a grease gun or the like which is a supply source of the adhesive. It is provided with an accumulator mechanism configured so that a part of the adhesive flows in and the gas inside is compressed when the adhesive is injected. Further, the pressure accumulator mechanism is configured such that a lid body is fitted into the tip end portion of the hollow cylinder, and a part of the lid body is attached so as to project inside the hollow container. In this way, the gas inside can be pre-compressed before the adhesive flows into the hollow container, and the pressure at which the adhesive is pushed toward the crack side is increased so that the adhesive spreads to the inside. Can be done.
また、前記蓋体は中空筒内部と連通する空圧調整弁を具備しており、当該空圧調整弁に筒などを差し込むことで内部の気体を外部に放出して蓄圧機構内を解圧したり、空圧調整弁を介して内部に空気を入れて加圧したりすることで接着剤の注入に適した圧力にすることもできる。 In addition, the lid body is provided with a pneumatic adjustment valve that communicates with the inside of the hollow cylinder, and by inserting a cylinder or the like into the air pressure adjustment valve, the gas inside is released to the outside to release the pressure inside the accumulator mechanism. It is also possible to obtain a pressure suitable for injecting an adhesive by injecting air into the inside through a pneumatic adjustment valve and pressurizing the pressure.
ところで、特許文献１の注入器であっても従来よりもクラックの隅々にまで接着剤を行きわたらせることができ、十分に有益な効果を奏し得るものではあるが、本願発明者は使い勝手等の面でさらなる改善の可能性について鋭意検討を行ったところ以下のような改善すべき点を見出した。 By the way, even with the injector of Patent Document 1, the adhesive can be spread to every corner of the crack as compared with the conventional case, and a sufficiently beneficial effect can be obtained. However, the inventor of the present application has the usability and the like. As a result of diligent examination of the possibility of further improvement in terms of, the following points to be improved were found.
例えば従来の注入器では蓄圧機構内の気体の圧力を調整して接着剤の注入に適した圧力に調整することはできるものの、例えば加圧する場合には既に接着剤で圧縮されている気体に対してさらに空気を送り込む必要があるため、大きな力をかけなくてはならない。また、解圧、加圧いずれの動作を行うにしても注入器以外の器具を用意しておかなくてはならない。さらに例えばクラックが近接して複数あり、そのそれぞれに注入器を設けた場合には、ある注入器に取り付けた加圧用のエアガンが別の注入器に干渉してしまうために取り付けにくく、加圧作業がやりにくいといったことが起こり得る。 For example, with a conventional injector, the pressure of the gas in the accumulator mechanism can be adjusted to a pressure suitable for injecting the adhesive, but for example, when pressurizing, the pressure of the gas already compressed by the adhesive can be adjusted. Since it is necessary to send more air, a large force must be applied. In addition, it is necessary to prepare an instrument other than the injector regardless of whether the operation is depressurization or pressurization. Further, for example, when there are a plurality of cracks in close proximity to each other and an injector is provided for each of them, it is difficult to install the air gun for pressurization attached to one injector because it interferes with another injector. It can happen that it is difficult to do.
本発明は上述したような問題を鑑みてなされたものであり、別途器具を用いなくても人力で大きな力を必要とせずに蓄圧機構内の気体を加圧でき、流動性補修材の注入に適した圧力へ簡単に調整できる流動性補修材注入器を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems, and can pressurize the gas in the accumulator mechanism without requiring a large force manually without using a separate instrument, and can be used for injecting a fluid repair material. It is an object of the present invention to provide a fluidity repair material injector that can be easily adjusted to a suitable pressure.
すなわち、本発明に係る流動性補修材注入器は、流動性補修材供給源と接続される接続口が基端に形成されており、補修対象と対向して取り付けられ、当該補修対象へ流動性補修材を注入する注入口が先端に形成された注入機構と、前記注入機構において前記接続口及び前記注入口の間から分岐しており、流動性補修材の注入時に流動性補修材の一部が流入して内部の気体が圧縮される蓄圧機構とを備え、前記蓄圧機構が、基端が前記注入機構に設けられ、先端が開口した中空筒と、前記中空筒内においてその基端及び先端の間をがたなく摺動可能に設けられた仕切り部材と、少なくとも一部が前記中空筒内の先端から基端側へと突出させて取り付けられ、前記中空筒の先端側を気密に封止する蓋体と、雄ねじと雌ねじからなり、前記中空筒と前記蓋体との間に形成された螺合構造と、を具備し、前記蓋体が前記中空筒に対して進退可能に構成されていることを特徴とする。 That is, the fluidity repair material injector according to the present invention has a connection port formed at the base end connected to the fluidity repair material supply source, is attached to face the repair target, and has fluidity to the repair target. An injection port for injecting the repair material is branched from between the injection mechanism formed at the tip and the connection port and the injection port in the injection mechanism, and a part of the fluid repair material is injected when the fluid repair material is injected. The accumulator mechanism is provided with an accumulator mechanism in which gas flows in and the gas inside is compressed, and the accumulator mechanism includes a hollow cylinder having a base end provided in the injection mechanism and an open tip, and the base end and the tip in the hollow cylinder. A partition member provided so as to be slidable without a gap is attached, and at least a part of the partition member projects from the tip end of the hollow cylinder toward the base end side, and the tip end side of the hollow cylinder is airtightly sealed. The lid body is composed of a male screw and a female screw, and has a screw structure formed between the hollow cylinder and the lid body, and the lid body is configured to be able to advance and retreat with respect to the hollow cylinder. It is characterized by being.
このようなものであれば、前記蓋体を前記中空筒に対して回転させることで当該中空筒に対して前記蓋体を進退させることができ、前記中空筒内へ蓋体の突出量を変化させて内部の気体の加圧量を調整することができる。このため、夏と冬の外気温の違い等による気体の膨張係数の違いから生まれる流動性補修材への圧力のばらつきがあったとしても、前記蓄圧機構内の圧力を流動性補修材が例えばクラック内にすみずみまで行きわたらせるのに適した圧力へ調整することが可能となる。 In such a case, by rotating the lid with respect to the hollow cylinder, the lid can be moved forward and backward with respect to the hollow cylinder, and the amount of protrusion of the lid into the hollow cylinder is changed. The amount of pressurization of the gas inside can be adjusted. Therefore, even if there is a variation in the pressure on the fluidity repair material caused by the difference in the expansion coefficient of the gas due to the difference in the outside air temperature between summer and winter, the fluidity repair material cracks the pressure in the accumulator mechanism, for example. It is possible to adjust the pressure to be suitable for spreading it all over the inside.
さらに、前記蓋体の前記中空筒内における突出量を変化させられるので、前記中空筒内へ流入できる流動性補修材の最大量も自由に設定できる。このため、クラックが浅い場合には前記中空筒内の容積を小さくして流動性補修材の量を少量にしたり、クラックが深い場合には前記中空筒内の容積を大きくして流動性補修材の量を多量にしたりできる。このため、注入される流動性補修材の量と加えられる圧力の組み合わせを自由に設定でき、安定した品質の工事の実施が可能となる。 Further, since the amount of protrusion of the lid body in the hollow cylinder can be changed, the maximum amount of the fluidity repair material that can flow into the hollow cylinder can be freely set. Therefore, when the crack is shallow, the volume inside the hollow cylinder is reduced to reduce the amount of the fluidity repair material, and when the crack is deep, the volume inside the hollow cylinder is increased to increase the fluidity repair material. The amount of can be increased. Therefore, the combination of the amount of the fluidity repair material to be injected and the pressure applied can be freely set, and it is possible to carry out construction with stable quality.
また、別途器具により内部に気体を注入する必要がなく、前記螺合構造により少しずつ前記蓋体を進退させることができるので前記流動性補修材注入器が取り付けられている状況によらず、人力で簡単に圧力の調整ができる。具体的には流動性補修材注入器が複数近接して設けられていたり、前記蓄圧機構が向いている方向が障害物の方向であったりしても、前記蓋体に手が届きさえすれば圧力の調整ができる。 Further, since it is not necessary to inject gas into the inside by a separate instrument and the lid body can be moved forward and backward little by little by the screw structure, human power is used regardless of the situation where the fluidity repair material injector is attached. You can easily adjust the pressure with. Specifically, even if a plurality of fluid repair material injectors are provided in close proximity to each other or the pressure accumulator mechanism is facing in the direction of an obstacle, as long as the lid can be reached. The pressure can be adjusted.
さらに、前記蓄圧機構内の圧力を低下させるには前記蓋体を回して後退させて前記中空筒内における前記蓋体の突出量を減らす方向に調整すればよい。つまり、中空筒内の気体を外部へ放出して解圧する場合には大気圧となってしまうため細かい調整が難しいのに対して本発明であれば圧力を低下させる場合でも調整の自由度が高い。また、注入作業が完了して前記流動性補修材注入器をクラックから流動性補修材が固まる前に取り外す際に前記蓄圧機構内を予め解圧すれば、前記仕切り部材が流動性補修材を押圧する力を小さくして取り外し時に前記注入口から流動性補修材が噴き出て周囲を汚してしまうことを防ぐことができる。さらに前記中空筒内は前記仕切り部材に仕切られているので、前記中空筒から前記蓋体が解圧時に取り外されたとしても前記中空筒の流動性補修材が前記中空筒の先端から外へと液だれしない。さらにクラックから外された前記流動性補修材注入器内に流動性補修材が残っており、まだ内部で固まっている等していない場合には、当該流動性補修材注入器を別のクラックに対して取り付けて、前記蓋体を回転させて内部の流動性補修材に圧力をかけて再度残っている流動性補修材を別のクラックに対して注入することもできる。 Further, in order to reduce the pressure in the accumulator mechanism, the lid may be rotated and retracted to adjust the amount of protrusion of the lid in the hollow cylinder. In other words, when the gas in the hollow cylinder is released to the outside to release the pressure, it becomes atmospheric pressure, so fine adjustment is difficult, whereas in the present invention, the degree of freedom of adjustment is high even when the pressure is lowered. .. Further, if the pressure accumulating mechanism is released in advance when the injection work is completed and the fluidity repair material injector is removed from the crack before the fluidity repair material hardens, the partition member presses the fluidity repair material. It is possible to prevent the fluidity repair material from being ejected from the injection port and polluting the surroundings at the time of removal by reducing the force. Further, since the inside of the hollow cylinder is partitioned by the partition member, even if the lid body is removed from the hollow cylinder at the time of decompression, the fluidity repair material of the hollow cylinder moves from the tip of the hollow cylinder to the outside. No dripping. Further, if the fluidity repair material remains in the fluidity repair material injector removed from the crack and is not yet solidified inside, the fluidity repair material injector is moved to another crack. On the other hand, the lid can be rotated to apply pressure to the fluid repair material inside to inject the remaining fluid repair material into another crack.
加えて、前記蓋体を前記中空筒に対して回転させるだけで良いのでいつでも圧力の調整が可能である。例えば流動性補修材が内部にクラック内へ行きわたらせるのに必要な量があるものの圧力不足でクラック内へ進行しない場合には、前記蓋体を回して前記蓄圧機構内を加圧し、流動性補修材を注入する事が可能となる。このため、蓄圧機構内を流入する流動性補修材以外の手段で加圧することができない注入器を用いていた場合、流動性補修材をクラック内へ進行させるために不要な量の流動性補修材を前記注入機構から追い足ししていたが、本発明であればこのような無駄も解消できる。あるいは、前記中空筒内に流動性補修材が流入する前の０ｃｃの段階から前記蓋体を前記中空筒内へとはまりこませて、内部の気体を圧縮して予圧できる。 In addition, the pressure can be adjusted at any time because it is only necessary to rotate the lid with respect to the hollow cylinder. For example, if the fluidity repair material has an amount required to spread inside the crack but does not proceed into the crack due to insufficient pressure, the lid is rotated to pressurize the inside of the accumulator mechanism to provide fluidity. It is possible to inject repair materials. For this reason, when an injector that cannot be pressurized by means other than the fluidity repair material flowing into the accumulator mechanism is used, an unnecessary amount of the fluidity repair material is used to advance the fluidity repair material into the crack. Was added from the injection mechanism, but with the present invention, such waste can be eliminated. Alternatively, the lid can be fitted into the hollow cylinder from the stage of 0 cc before the fluidity repair material flows into the hollow cylinder, and the gas inside can be compressed and preloaded.
また、複数のクラックが密集して形成されており、それぞれのクラックに対して流動性補修材注入器を取り付けるためのスペースが小さい場合には、注入作業開始前に前記中空筒の基端側へ前記蓋体を進行させて前記蓄圧機構全体の長さを予め短くした状態で取り付けて、隣接する流動性補修材注入器同士が干渉するのを防ぐことができる。すなわち、前記蓄圧機構内の圧力を適宜調整できるだけでなく、作業現場の状態に応じて流動性補修材の注入器の大きさを変更して作業をやりやすくすることができる。 Further, when a plurality of cracks are densely formed and the space for attaching the fluidity repair material injector is small for each crack, the hollow cylinder is moved to the base end side before the start of the injection work. It is possible to prevent the adjacent fluid repair material injectors from interfering with each other by advancing the lid and attaching the accumulator mechanism in a state where the entire length is shortened in advance. That is, not only can the pressure in the accumulator mechanism be adjusted as appropriate, but also the size of the fluidity repair material injector can be changed according to the state of the work site to facilitate the work.
前記蓄圧機構全体の長さ寸法を小さく構成することができるようにするには、前記蓋体が、前記中空筒内へ挿入される中栓体と、前記中栓体と外側端に接続され、前記中空筒の外側周面を覆うように設けられる外筒と、を具備し、前記雄ねじが、前記中空筒の外側周面に形成され、前記雌ねじが、前記外筒の内側周面に形成されたものであればよい。このようなものであれば、前記外筒が前記中空筒の外側周面を覆うように設けられているので、前記蓋体を回す際に把持される部分を螺合構造が形成されている部分とを前記中空筒の軸方向に対して近接させることができる。したがって、前記中空筒の内側周面と前記蓋体の外側周面との間に前記螺合構造を形成して前記蓋体において把持される部分を前記中空筒の外側へと出した場合と比較して、長さ寸法を小さくできる。さらに、前記外筒により前記中空筒の外側が覆われるように配置されるので、前記中空筒内の圧力が高くなり、当該中空筒自体が外側へ膨らもうとしても外筒により規制できる。また、仮に中空筒が膨らんだとしても前記中空筒と前記蓋体との間に形成された螺合構造がより強くかみ合うことになり、前記蓋体が前記中空筒からより外れにくくすることができる。 In order to make the length dimension of the entire pressure accumulator mechanism small, the lid body is connected to an inner plug body inserted into the hollow cylinder and to the inner plug body and the outer end. An outer cylinder provided so as to cover the outer peripheral surface of the hollow cylinder is provided, the male screw is formed on the outer peripheral surface of the hollow cylinder, and the female screw is formed on the inner peripheral surface of the outer cylinder. Anything is fine. In such a case, since the outer cylinder is provided so as to cover the outer peripheral surface of the hollow cylinder, a portion where a screw structure is formed on a portion gripped when turning the lid body. Can be brought close to the hollow cylinder in the axial direction. Therefore, as compared with the case where the screw structure is formed between the inner peripheral surface of the hollow cylinder and the outer peripheral surface of the lid body and the portion gripped by the lid body is extended to the outside of the hollow cylinder. Therefore, the length dimension can be reduced. Further, since the outer cylinder is arranged so as to cover the outside of the hollow cylinder, the pressure inside the hollow cylinder becomes high, and even if the hollow cylinder itself tries to expand outward, it can be regulated by the outer cylinder. Further, even if the hollow cylinder swells, the screw structure formed between the hollow cylinder and the lid body will be more strongly engaged, and the lid body can be made more difficult to come off from the hollow cylinder. ..
例えば前記中空筒が樹脂で形成されており、前記中空筒の外側周面に雄ねじを形成すると、成型時に樹脂の収縮によるヒケが生じ、前記中空筒の内側周面において前記雄ねじに対応する部分にわずかなくぼみが生じる。このようなヒケが生じても前記蓋体の前記中栓体によるシール効果を大きくし、内部の空気が加圧中等に外部へ漏れだしにくくするには、前記中栓体が、その外側周面から外側へ突き出した１又は複数の凸条を有するものであればよい。 For example, if the hollow cylinder is made of resin and a male screw is formed on the outer peripheral surface of the hollow cylinder, sink marks occur due to shrinkage of the resin during molding, and the portion corresponding to the male screw is formed on the inner peripheral surface of the hollow cylinder. There is a slight dent. Even if such a sink mark occurs, in order to increase the sealing effect of the inner plug body of the lid body and prevent the internal air from leaking to the outside during pressurization or the like, the inner plug body is formed on the outer peripheral surface thereof. It may have one or more ridges protruding outward from the surface.
前記蓋体をそれほど回転させてなくても前記蓋体が前記中空筒の軸方向に対して進退するようにして加圧の手間を減らせるようにするには、前記雄ねじ及び前記雌ねじにおいて、ネジ山の幅がねじ溝の幅よりも小さく形成されていればよい。なお、このようなものであれば前記雄ねじと前記雌ねじは互いにネジ山の一面だけしか接触しない状態になるが、前記中空筒内が加圧された状態であれば前記雄ねじと前記雌ねじは強く密着することになり、回転のトルクを十分に伝えて前記蓋体を少ない回転数で進退させることができる。 In order to reduce the time and effort of pressurization by moving the lid body forward and backward in the axial direction of the hollow cylinder without rotating the lid body so much, the male screw and the female screw are screwed. The width of the ridge may be smaller than the width of the thread groove. In such a case, the male screw and the female screw are in contact with each other on only one surface of the screw thread, but if the inside of the hollow cylinder is pressurized, the male screw and the female screw are strongly adhered to each other. Therefore, the torque of rotation can be sufficiently transmitted to move the lid body forward and backward at a small number of rotations.
このことにより前記中空筒内が加圧されているかどうかを簡単な操作で確認できるようにするには、前記中空筒内の空気が所定圧力以下の場合には、前記蓋体が前記中空筒の軸方向に対して押引き可能に構成されていればよい。 In order to make it possible to confirm by a simple operation whether or not the inside of the hollow cylinder is pressurized by this, when the air in the hollow cylinder is at a predetermined pressure or less, the lid body is formed of the hollow cylinder. It suffices if it is configured to be pushable and pullable in the axial direction.
前記流動性補修材供給源を前記注入機構から外した際に、補修対象からの逆流により前記接続口から流動性補修材が漏れてしまい、周囲を汚すことが無いようにするには、前記注入機構が、前記注入口が形成されており、前記補修対象に取り付けられる座金と、先端が前記座金に取り付けられ、側面に前記中空容器が接続された筒状本体と、前記筒状本体の基端側に挿入されており、前記接続口を形成する逆止弁とから構成されていればよい。 In order to prevent the fluidity repair material from leaking from the connection port due to the backflow from the repair target when the fluidity repair material supply source is removed from the injection mechanism and polluting the surroundings, the injection is performed. The mechanism consists of a washer having the injection port formed and attached to the repair target, a tubular main body having a tip attached to the washer and the hollow container connected to a side surface, and a base end of the tubular main body. It suffices if it is inserted on the side and is composed of a check valve that forms the connection port.
前記流動性補修材供給源から加えられる圧力が前記補修対象内へと進行していく流動性補修材に無駄なく伝達され、効率よく注入作業を進められるようにするには、前記接続口、前記筒状本体、及び、前記注入口の中心軸が一直線上にならぶように配置されていればよい。 In order to efficiently transmit the pressure applied from the fluidity repair material supply source to the fluidity repair material advancing into the repair target so that the injection work can proceed efficiently, the connection port, the above. The tubular main body and the central axis of the injection port may be arranged so as to be aligned with each other.
前記蓄圧機構内へ流入した流動性補修材が前記中空筒内の気体の圧力により前記注入機構内へとスムーズに戻り、補修対象であるクラック内等へ効率よく充填されるようにするには、前記筒状本体と前記中空筒との間を連通する連通孔が、前記中空筒の基端の中心部に形成されていればよい。 In order to ensure that the fluidity repair material that has flowed into the accumulator mechanism smoothly returns to the injection mechanism due to the pressure of the gas in the hollow cylinder and is efficiently filled in the crack or the like to be repaired. A communication hole for communicating between the tubular main body and the hollow cylinder may be formed at the center of the base end of the hollow cylinder.
注入作業が完了してクラックから取り外された後に前記流動性補修材注入器内に流動性補修材が残っている状態で放置されて硬化した場合に、例えば流動性補修材が流通できる程度に洗浄して再利用されることがある。このような場合、新しい流動性補修材と十分に洗浄されずに内部に残っている流動性補修材が混合された状態でクラックに注入されて工事の品質が低下する事があり得る。このような問題が生じないようにするために流動性補修材が内部で硬化してしまった場合には以降は注入作業に使用できないようにして、工事の品質を保証できるようにするには、前記筒状本体の内部において少なくとも一部が基端側から前記先端側へ進むほど先細るように構成されており、前記逆止弁が、前記筒状本体の基端側に溶着されていればよい。このようなものであれば、前記筒状本体内が先細り構造を有しているので硬化した流動性補修材は前記注入口から取り出すことはできない。また、前記筒状本体に溶着されている逆止弁を無理に外して内部の硬化した流動性補修材を取り出してしまうと、逆止弁が機能しなくなるため、前記接続口から流動性補修材を供給できなくなってしまう。したがって、流動性補修材が内部で硬化した場合には本発明の流動性補修材を再利用できなくすることができ、工事の品質を保証することができる。一方、流動性補修材が硬化する前であれば前記蓋体による加圧によって内部に残っている流動性補修材をクラック等に注入できるので、このような構造を設けても通常の注入には妨げにならず、再利用の防止のみを実現できる。 When the fluidity repair material is left in the state where the fluidity repair material remains in the syringe after the injection work is completed and removed from the crack and hardened, for example, the fluidity repair material is washed to the extent that it can be distributed. May be reused. In such a case, the new fluidity repair material and the fluidity repair material remaining inside without being sufficiently cleaned may be injected into the crack in a mixed state, and the quality of the construction may be deteriorated. In order to prevent such problems, if the fluidity repair material has hardened internally, it can no longer be used for injection work, and the quality of construction can be guaranteed. If at least a part of the inside of the tubular body is tapered from the proximal end side toward the distal end side, and the check valve is welded to the proximal end side of the tubular body. Good. In such a case, since the inside of the tubular body has a tapered structure, the cured fluid repair material cannot be taken out from the injection port. Further, if the check valve welded to the tubular body is forcibly removed and the cured fluidity repair material inside is taken out, the check valve will not function, so that the fluidity repair material will not function from the connection port. Can no longer be supplied. Therefore, when the fluidity repair material is hardened internally, the fluidity repair material of the present invention cannot be reused, and the quality of construction can be guaranteed. On the other hand, before the fluidity repair material is cured, the fluidity repair material remaining inside can be injected into cracks or the like by pressurization by the lid, so even if such a structure is provided, normal injection can be performed. It does not interfere and can only prevent reuse.
このように本発明に係る流動性補修材注入器によれば、前記蓋体と前記中空筒との間に螺合構造が形成されており、前記蓋体を回転させるだけで、前記蓋体の前記中空筒内における突出量を変えて、内分の気体圧力をいつでも簡単に調整できる。また、前記螺合構造が形成されているので前記中空筒内に圧力がかかっている状態でもそれほど大きな力で前記蓋体を回さなくても前記蓋体を進行させることができ、従来よりも小さな力で圧力の調整作業を行うことができる。したがって、本発明に係る流動性補修材によれば、補修対象であるクラックの大きさや形状、さらに周囲の温度等に応じて適切な圧力を前記蓄圧機構内に収容されている流動性補修材へかけて工事の品質を一定に保つことができる。 As described above, according to the fluidity repair material injector according to the present invention, a screw structure is formed between the lid body and the hollow cylinder, and the lid body can be formed by simply rotating the lid body. By changing the amount of protrusion in the hollow cylinder, the gas pressure inside can be easily adjusted at any time. Further, since the screw structure is formed, the lid can be advanced even when pressure is applied to the hollow cylinder without turning the lid with such a large force, which is more than before. The pressure can be adjusted with a small force. Therefore, according to the fluidity repair material according to the present invention, an appropriate pressure is applied to the fluidity repair material housed in the accumulator mechanism according to the size and shape of the crack to be repaired, the ambient temperature, and the like. The quality of construction can be kept constant.
本発明の一実施形態に係る流動性補修材注入器について各図を参照しながら説明する。 The fluidity repair material injector according to the embodiment of the present invention will be described with reference to each figure.
本実施形態の流動性補修材注入器は、土木工事等においてコンクリート構造物Ｃ等に生じた補修対象であるクラックＡＯに流動性補修材として接着剤Ｌを注入する補修作業に用いられる接着剤注入器１００である。より具体的には図１の斜視図に示すようにこの接着剤注入器１００は、コンクリート構造物ＣにおいてクラックＡＯが外表面に開口している部分に固定されて、接着剤Ｌの供給源であるグリスガン等の仲介をする。そして、この接着剤注入器１００を構成する部品は金属を使用せずに樹脂により形成されており、使用後は分別等を行うことなくそのまま全体を廃棄できるようにしてある。 The fluidity repair material injector of the present embodiment is used for the adhesive injection used in the repair work of injecting the adhesive L as the fluidity repair material into the crack AO which is the object of repair generated in the concrete structure C or the like in civil engineering work or the like. It is a vessel 100. More specifically, as shown in the perspective view of FIG. 1, the adhesive injector 100 is fixed to a portion of the concrete structure C where the crack AO is open to the outer surface, and is a source of the adhesive L. Mediate a certain grease gun, etc. The parts constituting the adhesive injector 100 are made of resin without using metal, and after use, the entire parts can be discarded as they are without sorting or the like.
この接着剤注入器１００は、補修対象のあるコンクリート構造物Ｃ等に対して垂直に取り付けられる部分であり、グリスガンからクラックＡＯへと接着剤Ｌが流通する注入機構ＩＮと、前記注入機構ＩＮに対して直交するように分岐させて設けてあり、グリスガンにより接着剤Ｌが注入されている時に接着剤Ｌの一部が内部へ流入して内部の気体Ｇが圧縮されるように構成してある蓄圧機構ＴＮとからなるものである。 The adhesive injector 100 is a portion that is vertically attached to the concrete structure C or the like to be repaired, and is attached to the injection mechanism IN through which the adhesive L flows from the grease gun to the crack AO and the injection mechanism IN. It is provided so as to be branched so as to be orthogonal to each other, and is configured so that when the adhesive L is injected by the grease gun, a part of the adhesive L flows into the inside and the gas G inside is compressed. It is composed of a pressure accumulator mechanism TN.
図１及び図２の斜視図に示すように前記注入機構ＩＮは、この接着剤注入器１００において細円筒状の部分であり、基端に接着剤供給源であるグリスガンに接続される接続口ＣＰが形成してあり、先端にクラックＡＯと対向して取り付けられ、当該クラックＡＯへ接着剤Ｌを注入する注入口ＩＰが形成してある。 As shown in the perspective views of FIGS. 1 and 2, the injection mechanism IN is a thin cylindrical portion of the adhesive injector 100, and is connected to a grease gun as an adhesive supply source at the base end. Is formed, and is attached to the tip of the crack AO so as to face the crack AO, and an injection port IP for injecting the adhesive L into the crack AO is formed.
より具体的には、図３の分解図に示すように前記注入機構ＩＮは、前記注入口ＩＰが形成されており、クラックＡＯのあるコンクリート構造物Ｃに取り付けられる座金１と、先端が前記座金１に取り付けられ、側面に前記中空容器４が接続された筒状本体２と、前記筒状本体２の基端側に挿入されており、前記接続口ＣＰを形成する逆止弁３とから構成してある。 More specifically, as shown in the exploded view of FIG. 3, the injection mechanism IN has a washer 1 having an injection port IP formed therein and attached to a concrete structure C having a crack AO, and a washer having a tip thereof. It is composed of a tubular main body 2 attached to 1 and to which the hollow container 4 is connected to a side surface, and a check valve 3 which is inserted into the base end side of the tubular main body 2 and forms the connection port CP. It is done.
前記座金１は、中央部に前記注入口ＩＰが開口する薄円板部１１と、その注入口ＩＰを囲い前記薄円板部１１の上面に対して垂直に突出した円筒部１２とからなる。前記薄板円板部１１の下面外周部は、クラックＡＯの開口している周囲の壁面に固定材Ｆにより粘着されて固定される。この固定材Ｆは圧縮又は引っ張り方向には強い粘性を示すが、せん断方向には弱い粘性を示すためクラックＡＯ内に接着剤Ｌを注入した後で前記接着剤注入器１００を取り外す際には、壁の表面に沿った方向に移動させることで容易に取り外すことができる。前記円筒部１２は中空であって、内部に前記筒状本体２と螺合するめねじが切ってある。 The washer 1 is composed of a thin disk portion 11 in which the injection port IP opens in the central portion, and a cylindrical portion 12 that surrounds the injection port IP and projects perpendicularly to the upper surface of the thin disk portion 11. The outer peripheral portion of the lower surface of the thin disk portion 11 is adhered to and fixed to the surrounding wall surface where the crack AO is open by the fixing material F. This fixing material F exhibits a strong viscosity in the compression or tension direction, but exhibits a weak viscosity in the shear direction. Therefore, when the adhesive L is injected into the crack AO and then the adhesive injector 100 is removed, the adhesive injector 100 is removed. It can be easily removed by moving it along the surface of the wall. The cylindrical portion 12 is hollow, and a female screw to be screwed with the tubular main body 2 is cut inside.
前記筒状本体２は、図３に示すように前記円筒部１２よりも細い中空円筒状のものであり、基端側には前記逆止弁３において平円板リング状に形成された溶着部３１が例えば熱溶着される台座部２３が形成してある。なお、溶着部３１は台座部２３に対して溶着してあればよく、熱溶着以外の方法で溶着させてもよい。そして、この筒状本体２の内部では前記逆止弁３の胴体部３２が収容される。また、前記筒状本体２の先端の外側周面に前記円筒部１２と螺合するおねじ２１が切ってある。さらに、前記筒状本体２は図３（ｂ）の断面図に示すようにその側面中央部であり、前記逆止弁３が収容された状態での先端近傍に前記蓄圧機構ＴＮ内と連通する連通孔２２が形成してある。この筒状本体２の内部は基端側から先端側に進むにつれて先細るように構成してあり、筒状本体２内で接着剤が硬化した場合には先端側から取り出せないように構成してある。また、前記台座部２３に対しては前記逆止弁３の溶着部３１が溶着されているので基端側からも硬化した接着剤は取り出すことはできない。仮に逆止弁３を無理に前記筒状本体２から取り外した場合には当該逆止弁３は固定されずその機能が発揮されないため前記筒状本体２からクラックＡＯ内に対して接着剤に圧力をかけて注入することができなくなる。したがって、筒状本体２内において余った接着剤が硬化するほど放置されていた場合には前記接着剤注入器１００を再利用することはできず、古い接着剤と新しい接着剤が混ざった状態でクラックＡＯ内に注入されて低品質の補修工事が実施されることを未然に防ぐことができる。 As shown in FIG. 3, the tubular main body 2 has a hollow cylindrical shape thinner than the cylindrical portion 12, and a welded portion formed in a flat disk ring shape on the check valve 3 on the base end side. A pedestal portion 23 is formed in which 31 is heat-welded, for example. The welded portion 31 may be welded to the pedestal portion 23, and may be welded by a method other than heat welding. The body portion 32 of the check valve 3 is housed inside the tubular main body 2. Further, a male screw 21 to be screwed with the cylindrical portion 12 is cut on the outer peripheral surface of the tip of the tubular main body 2. Further, the tubular main body 2 is the central portion of the side surface as shown in the cross-sectional view of FIG. 3B, and communicates with the inside of the pressure accumulating mechanism TN near the tip of the check valve 3 in a housed state. A communication hole 22 is formed. The inside of the tubular body 2 is configured to taper as it progresses from the base end side to the tip end side, and when the adhesive hardens in the tubular body 2, it is configured so that it cannot be taken out from the tip end side. is there. Further, since the welded portion 31 of the check valve 3 is welded to the pedestal portion 23, the cured adhesive cannot be taken out from the base end side as well. If the check valve 3 is forcibly removed from the tubular main body 2, the check valve 3 is not fixed and its function is not exhibited. Therefore, pressure is applied to the adhesive from the tubular main body 2 into the crack AO. It becomes impossible to inject with. Therefore, if the excess adhesive is left to cure in the tubular main body 2, the adhesive injector 100 cannot be reused, and the old adhesive and the new adhesive are mixed. It is possible to prevent the crack AO from being injected into the crack AO and carrying out low-quality repair work.
前記逆止弁３はグリスガンが差し込まれた状態ではその胴体部３２の先端が開き、前記筒状本体２内へ接着剤Ｌが流通するが、グリスガンが外された状態では先端部の切込みが閉止されて、筒状本体２内の接着剤Ｌが接続口ＣＰから外部へと流出しないように構成してある。この逆止弁３はエラストマー等の柔軟性を有した樹脂で形成して、グリスガンを前記筒状本体２の軸方向と完全に合致しておらず、多少斜めに傾いた状態でも接続でき、その接続のしやすさを向上させてある。また、前述したように胴体部３２の外径は、筒状本体２の内径よりも小さく設定してあるので、組立時にはこの筒状本体２に胴体部３２を挿入しやすい。さらに、前記台座部２３に対して前記溶着部３１のみを溶着するので、前記筒状本体２に対して前記逆止弁３により気密を保ちながら固定して組み付けしやすい。 When the check valve 3 is inserted with the grease gun, the tip of the body portion 32 opens and the adhesive L flows into the tubular main body 2, but when the grease gun is removed, the notch at the tip portion is closed. Therefore, the adhesive L in the tubular main body 2 is configured so as not to flow out from the connection port CP. The check valve 3 is made of a flexible resin such as an elastomer, and the grease gun is not completely aligned with the axial direction of the tubular main body 2 and can be connected even in a slightly inclined state. The ease of connection has been improved. Further, as described above, since the outer diameter of the body portion 32 is set to be smaller than the inner diameter of the tubular main body 2, it is easy to insert the body portion 32 into the tubular main body 2 at the time of assembly. Further, since only the welding portion 31 is welded to the pedestal portion 23, it is easy to fix and assemble the tubular main body 2 with the check valve 3 while maintaining airtightness.
また、前記注入機構ＩＮを構成する、前記座金１、前記筒状本体２、及び、前記逆止弁３はそれぞれの中心軸が一直線上で合致するように構成してあるので、前記接続口ＣＰに接続されたグリスガンからクラックＡＯに向かって接着剤Ｌが押し出された際に、その力をほとんどロスすることなく伝達させることができる。したがって、クラックＡＯ内に埃や砂粒等で閉塞されている箇所があったとしても、接着剤Ｌの圧力により飛ばしながらクラックＡＯ内のすみずみまで接着剤Ｌを行きわたらせることができる。 Further, since the washer 1, the tubular main body 2, and the check valve 3 constituting the injection mechanism IN are configured so that their central axes coincide with each other on a straight line, the connection port CP When the adhesive L is extruded from the grease gun connected to the crack AO toward the crack AO, the force can be transmitted with almost no loss. Therefore, even if there is a portion in the crack AO that is blocked by dust, sand particles, or the like, the adhesive L can be spread throughout the crack AO while being blown off by the pressure of the adhesive L.
次に前記蓄圧機構ＴＮについて説明する。 Next, the accumulator mechanism TN will be described.
前記蓄圧機構ＴＮは、図１及び図２に示すように前記接着剤注入器１００において太円筒部分に相当するものであり、基端が前記注入機構ＩＮに取り付けられ、先端が開口した中空筒４と、前記中空筒４内においてその基端及び先端の間をがたなく摺動可能に設けられた仕切り部材５と、前記中空筒４の先端部を気密に封止する蓋体６とを具備するものである。すなわち、この蓄圧機構ＴＮは前記中空筒４と前記蓋体６の２つの分割されたパーツで構成してある。また、前記中空筒４は、前記筒状本体２と組み合わされた状態で、1つのパーツとして一体成型してある。さらに、前記中空筒４は、前記筒状本体２に対して直交するように設けてあり、クラックＡＯから見て前記筒状本体２の基端と前記中空筒４の反クラック側の側面が略同じ高さにあるようにしてある。 As shown in FIGS. 1 and 2, the pressure accumulator mechanism TN corresponds to a thick cylindrical portion in the adhesive injector 100, and a hollow cylinder 4 having a base end attached to the injection mechanism IN and an open tip. A partition member 5 is provided so as to be slidable between the base end and the tip of the hollow cylinder 4, and a lid 6 for airtightly sealing the tip of the hollow cylinder 4. Is what you do. That is, the accumulator mechanism TN is composed of two divided parts, the hollow cylinder 4 and the lid 6. Further, the hollow cylinder 4 is integrally molded as one part in a state of being combined with the tubular main body 2. Further, the hollow cylinder 4 is provided so as to be orthogonal to the tubular main body 2, and the base end of the tubular main body 2 and the side surface of the hollow cylinder 4 on the anti-crack side are substantially defined as viewed from the crack AO. It is designed to be at the same height.
また、本実施形態では前記中空筒４の先端側外側周面と前記蓋体６との間には雄ねじ７１と雌ねじ７２からなる螺合構造７が形成してあり、前記蓋体６は前記中空筒に対して軸方向に進退可能に構成してある。このため、前記蓋体６を回転させることで前記蓋体６の前記中空筒４内における突出量を変更し、前記中空筒４内における前記仕切り部材５と前記蓋体６との間の気体の圧力を加圧又は減圧できる。 Further, in the present embodiment, a screw structure 7 composed of a male screw 71 and a female screw 72 is formed between the outer peripheral surface on the tip end side of the hollow cylinder 4 and the lid body 6, and the lid body 6 is hollow. It is configured so that it can move forward and backward in the axial direction with respect to the cylinder. Therefore, by rotating the lid body 6, the amount of protrusion of the lid body 6 in the hollow cylinder 4 is changed, and the gas between the partition member 5 and the lid body 6 in the hollow cylinder 4 is changed. The pressure can be increased or decreased.
前記中空筒４は概略中空円筒形状をなす透明樹脂によりその内部が透けて見えるように構成したシリンダである。図１乃至３に示すようにこの中空筒４の外側周面には基端側から先端側へと目盛が付してあり、前記注入機構ＩＮから当該中空筒４内に流入した接着剤Ｌの量が目視で分かるようにしてある。また、この中空筒４の先端側には前記蓋体６が取り付けられる雄ねじ７１が形成してある。前記中空筒４の先端部と前記注入機構ＩＮの側面との間を連通する連通孔は中空筒４の基端面の中心に開口させてあり、前記仕切り部材５により押し出される接着剤Ｌが注入機構ＩＮ内へスムーズに流入するようにしてある。 The hollow cylinder 4 is a cylinder configured so that the inside thereof can be seen through by a transparent resin having a substantially hollow cylindrical shape. As shown in FIGS. 1 to 3, the outer peripheral surface of the hollow cylinder 4 is provided with a scale from the base end side to the tip end side, and the adhesive L flowing into the hollow cylinder 4 from the injection mechanism IN The amount is visually recognizable. Further, a male screw 71 to which the lid body 6 is attached is formed on the tip end side of the hollow cylinder 4. A communication hole that communicates between the tip of the hollow cylinder 4 and the side surface of the injection mechanism IN is opened at the center of the base end surface of the hollow cylinder 4, and the adhesive L extruded by the partition member 5 is the injection mechanism. It is designed to flow smoothly into the IN.
前記仕切り部材５は、前記中空筒４の内側周面と気密に篏合するものであり、当該中空筒４の内径と略同じ直径を有した概略扁平中実円筒状のピストンである。この仕切り部材５は注入開始時に前記中空筒４の基端に略密着した状態となるように取り付けてあり、前記注入機構ＩＮに接続されたグリスガンにより接着剤Ｌの注入が開始されて、前記中空筒４内にも接着剤Ｌが入ってくると中空筒４の先端側へと移動していくようにしてある。この際、前記中空筒４内は前記仕切り部材５により仕切られているので、中空筒４内の先端側には気体Ｇのみが存在し、中空筒４内の基端側にのみ接着剤Ｌがある状態になる。つまり、前記中空筒４内に封入されていた気体Ｇは前記仕切り部材５があるために前記注入機構ＩＮ側にある接着剤Ｌ内へは漏れ出ない。したがって、接着剤Ｌ内に気泡が発生することもなく、クラックＡＯ内で「す」が入った状態で接着剤Ｌが固まるような不十分な補修結果となることを防げる。 The partition member 5 is an airtightly fitted with the inner peripheral surface of the hollow cylinder 4, and is a substantially flat solid cylindrical piston having a diameter substantially the same as the inner diameter of the hollow cylinder 4. The partition member 5 is attached so as to be substantially in close contact with the base end of the hollow cylinder 4 at the start of injection, and the injection of the adhesive L is started by the grease gun connected to the injection mechanism IN, and the hollow When the adhesive L also enters the cylinder 4, it moves to the tip side of the hollow cylinder 4. At this time, since the inside of the hollow cylinder 4 is partitioned by the partition member 5, only the gas G exists on the tip side in the hollow cylinder 4, and the adhesive L exists only on the base end side in the hollow cylinder 4. It will be in a certain state. That is, the gas G sealed in the hollow cylinder 4 does not leak into the adhesive L on the IN side of the injection mechanism because of the partition member 5. Therefore, no bubbles are generated in the adhesive L, and it is possible to prevent an insufficient repair result in which the adhesive L hardens in a state where "su" is contained in the crack AO.
また、この仕切り部材５の厚みについては、前記連通孔２２から接着剤Ｌが前記中空筒４内に流入して押された際に当該仕切り部材５が倒れず、その平板部分が前記中空筒４の半径方向断面と平行となった姿勢のままで摺動するように設定してある。 Regarding the thickness of the partition member 5, when the adhesive L flows into the hollow cylinder 4 from the communication hole 22 and is pushed, the partition member 5 does not fall down, and the flat plate portion thereof is the hollow cylinder 4. It is set to slide in a posture parallel to the radial cross section of.
前記蓋体６は、前記中空筒４の内部において先端から基端側へ一部を突出させた状態で取り付けられるとともに、その突出量が任意に変更できるように構成してある。また、この蓋体６により前記中空筒４内の先端側、すなわち前記中空筒４内において前記仕切り部材５と前記蓋体６との間は気密に封止されるようにしてある。 The lid 6 is attached inside the hollow cylinder 4 with a part protruding from the tip to the proximal end side, and the protruding amount can be arbitrarily changed. Further, the lid 6 is hermetically sealed between the partition member 5 and the lid 6 on the tip end side in the hollow cylinder 4, that is, in the hollow cylinder 4.
より具体的には、図４の断面拡大図に示すように前記蓋体６は、前記中空筒内へ挿入される中栓体６１と、前記中栓体６１と外側端に接続され、前記中空筒の外側周面を覆うように設けられる外筒６２と、を具備する二重管構造を有するものである。 More specifically, as shown in the enlarged cross-sectional view of FIG. 4, the lid 6 is connected to the inner plug 61 inserted into the hollow cylinder, the inner plug 61, and the outer end, and is hollow. It has a double-tube structure including an outer cylinder 62 provided so as to cover the outer peripheral surface of the cylinder.
前記中栓体６１は、概略中空円筒状でその外径が前記中空筒４の内径とほぼ同じもしくは若干大きく形成してある。前記中栓体６１の外側周面には半径方向外側に吐出する複数の凸条６３が形成してある。前記凸条６３は前記中空筒４に形成されている雄ねじ７１のねじ山間の距離とほぼ同じ間隔で設けてある。ここで、樹脂成型により中空筒４の雄ねじ７１を形成すると収縮により引けが生じ中空筒の内側周面において雄ねじ７１の裏側に当たる部分が半径方向外側へ若干凹む部分が存在する。前記凸条６３はこのような凹みがあっても前記中栓体６１が中空筒４の内側周面に対して当接するので、気密性を保つことができる。 The inner plug 61 has a substantially hollow cylindrical shape, and its outer diameter is formed to be substantially the same as or slightly larger than the inner diameter of the hollow cylinder 4. A plurality of protrusions 63 that discharge outward in the radial direction are formed on the outer peripheral surface of the inner plug body 61. The ridges 63 are provided at substantially the same distance as the distance between the threads of the male screw 71 formed in the hollow cylinder 4. Here, when the male screw 71 of the hollow cylinder 4 is formed by resin molding, shrinkage occurs due to shrinkage, and there is a portion of the inner peripheral surface of the hollow cylinder where the portion corresponding to the back side of the male screw 71 is slightly recessed outward in the radial direction. Even if the ridge 63 has such a dent, the inner plug 61 comes into contact with the inner peripheral surface of the hollow cylinder 4, so that the airtightness can be maintained.
前記外筒６２は前記蓋体６が前記中空筒４に対して取り付けられた状態において前記中空筒４の先端側外側周面を覆うものであり、その内側周面には雌ねじ７２が形成してある。前記外筒６２は前記中栓体６１とほぼ同じ軸方向長さを有しており、同心軸状に配置してある。また前記外筒６２の外側周面には軸方向に延びるリブが複数等間隔で形成してあり、ユーザが手で掴んで滑らないように把持部が形成してある。 The outer cylinder 62 covers the outer peripheral surface on the tip end side of the hollow cylinder 4 in a state where the lid 6 is attached to the hollow cylinder 4, and a female screw 72 is formed on the inner peripheral surface thereof. is there. The outer cylinder 62 has substantially the same axial length as the inner plug 61, and is arranged concentrically. Further, a plurality of ribs extending in the axial direction are formed on the outer peripheral surface of the outer cylinder 62 at equal intervals, and grip portions are formed so that the user does not grip and slip by hand.
前記螺合構造７は、前記中空筒４の外側周面に形成された雄ねじ７１と前記蓋体６の外筒６２の内側周面に形成された雌ねじ７２とから構成してあり、ネジ山の幅がねじ溝の幅よりも小さく形成してある。言い換えると、本実施形態では雄ねじ７１と雌ねじ７２のネジ山は一方の側面のみが当接した状態で係合するようにしてある。このため、図５（ａ）、図５（ｂ）に示すように前記中空筒４内の気体が所定圧力に達していない状態では、前記蓋体６は回さなくても軸方向にスライド移動可能である。言い換えると、前記蓋体６により中空筒４内が十分に加圧され、接着剤ＬがクラックＡＯ内へと導入されるのに適した圧力がかかっているかどうかについてユーザは蓋体６を軸方向に押し込んだ時の触感等でも簡単に確認できる。また、仕切り部材５の動きによっても内部の圧力状態を把握でき、その管理が容易である。 The screw structure 7 is composed of a male screw 71 formed on the outer peripheral surface of the hollow cylinder 4 and a female screw 72 formed on the inner peripheral surface of the outer cylinder 62 of the lid body 6. The width is formed smaller than the width of the thread groove. In other words, in the present embodiment, the threads of the male screw 71 and the female screw 72 are engaged in a state where only one side surface is in contact with each other. Therefore, as shown in FIGS. 5 (a) and 5 (b), when the gas in the hollow cylinder 4 does not reach a predetermined pressure, the lid 6 slides in the axial direction without turning. It is possible. In other words, the user axially presses the lid 6 to determine whether the lid 6 sufficiently pressurizes the inside of the hollow cylinder 4 and applies a pressure suitable for introducing the adhesive L into the crack AO. You can easily check the tactile sensation when you push it into the lid. Further, the internal pressure state can be grasped by the movement of the partition member 5, and its management is easy.
このように構成された本実施形態の接着剤注入器１００の使用方法について図１、図２、図６を参照しながら説明する。 A method of using the adhesive injector 100 of the present embodiment configured in this way will be described with reference to FIGS. 1, 2, and 6.
まず、接着剤注入器は図１に示されるように壁等のクラック開口を塞ぐように取り付けられ、その後接続口ＣＰにグリスガンが接続されて接着剤Ｌが注入される。なお、接着剤Ｌの注入開始前は図１に示されるように仕切り部材５は前記中空筒４の基端側にある。グリスガンからは少なくとも前記蓄圧機構ＴＮ内に所定量以上の接着剤Ｌが流入するようにして図６（ａ）に示されるように前記仕切り部材５は中空筒の先端側まで接着剤Ｌにより移動する。この状態になった時点でグリスガンは外される。この結果、仕切り部材５と前記蓋体６の中栓体６１の先端との間にある気体は圧縮されて加圧された状態となり、前記仕切り部材５は中空筒４の先端側へと押されることになる。このため、クラックＡＯ内の流路抵抗があったとしても中空筒４内の接着剤ＬはクラックＡＯ内へ押し流されることになる。 First, the adhesive injector is attached so as to close a crack opening such as a wall as shown in FIG. 1, and then a grease gun is connected to the connection port CP to inject the adhesive L. Before the start of injection of the adhesive L, the partition member 5 is on the base end side of the hollow cylinder 4 as shown in FIG. As shown in FIG. 6A, the partition member 5 is moved by the adhesive L to the tip end side of the hollow cylinder so that at least a predetermined amount or more of the adhesive L flows into the accumulator mechanism TN from the grease gun. .. When this happens, the grease gun is removed. As a result, the gas between the partition member 5 and the tip of the inner plug 61 of the lid 6 is compressed and pressurized, and the partition member 5 is pushed toward the tip of the hollow cylinder 4. It will be. Therefore, even if there is a flow path resistance in the crack AO, the adhesive L in the hollow cylinder 4 will be washed away into the crack AO.
しばらくすると図６（ｂ）に示されるように前記蓄圧機構ＴＮ内の接着剤ＬがクラックＡＯ内に流入して減少する事により前記中空筒４内において前記仕切り部材５と前記中栓体６１との間の空間が拡大し、気体が減圧して接着剤Ｌが押される力が小さくなってしまう。 After a while, as shown in FIG. 6B, the adhesive L in the accumulator mechanism TN flows into the crack AO and decreases, so that the partition member 5 and the inner plug 61 are formed in the hollow cylinder 4. The space between them expands, the gas is depressurized, and the force with which the adhesive L is pushed becomes small.
接着剤注入器１００内に残っている少量の接着剤ＬをクラックＡＯ内にさらに充填してクラックＡＯ内のすみずみまで接着剤Ｌを十分に行きわたらせるためにユーザは前記蓋体６を中空筒４に対して回転させることで中空筒４の基端側に移動させる。この結果、図６（ｃ）に示されるように中空筒４内における仕切り部材５と中栓体６１との間の空間は圧縮されて再び内部を加圧できる。このため、中空筒内に少量の接着剤Ｌが残っている場合でも再びグリスガンで接着剤Ｌを追い足ししなくてもクラックＡＯ内へと注入することができる。 In order to further fill the crack AO with a small amount of the adhesive L remaining in the adhesive injector 100 and sufficiently distribute the adhesive L to every corner of the crack AO, the user hollows out the lid 6. By rotating with respect to the cylinder 4, it is moved to the base end side of the hollow cylinder 4. As a result, as shown in FIG. 6C, the space between the partition member 5 and the inner plug 61 in the hollow cylinder 4 is compressed and the inside can be pressurized again. Therefore, even if a small amount of the adhesive L remains in the hollow cylinder, it can be injected into the crack AO without adding the adhesive L again with a grease gun.
加えて、接着剤注入器１００を壁から外す場合には前記蓋体６を回転させて中空筒４の先端側へ移動させて解圧することで接着剤Ｌへの圧力を小さくし、取り外す際に注入口から接着剤Ｌが飛び散らないようにすることもできる。 In addition, when the adhesive injector 100 is removed from the wall, the lid 6 is rotated and moved to the tip side of the hollow cylinder 4 to release the pressure, thereby reducing the pressure on the adhesive L and when removing the adhesive L. It is also possible to prevent the adhesive L from splashing from the injection port.
このように本実施形態の接着剤注入器１００によれば、前記蓋体６が前記螺合構造７により前記中空筒４の軸方向に対して進退可能に設けられているので、前記中空筒４内の気体の圧縮状態を適宜変更してクラックＡＯ内に接着剤Ｌを注入するのに適した圧力を保つことが工具等を用いずに簡単にできる。 As described above, according to the adhesive injector 100 of the present embodiment, the lid 6 is provided by the screw structure 7 so as to be able to advance and retreat in the axial direction of the hollow cylinder 4, so that the hollow cylinder 4 It is possible to easily maintain a pressure suitable for injecting the adhesive L into the crack AO by appropriately changing the compressed state of the gas inside without using a tool or the like.
また、前記螺合構造７があるので前記中空筒４内の気体が圧縮されて抵抗力が大きくなってもそれほど大きな力を加えなくても前記蓋体６を前記中空筒４内へと押し込んでいくことができ、加圧に必要となる力を従来よりも小さくできる。 Further, since the screw structure 7 is provided, the lid 6 is pushed into the hollow cylinder 4 even if the gas in the hollow cylinder 4 is compressed and the resistance is increased without applying a large force. The force required for pressurization can be made smaller than before.
さらに前記蓋体６は二重管構造を有しており、ユーザにより把持される前記外筒６２と前記中栓体６１の軸方向の位置をほぼ同じにすることができるので、前記蓄圧機構ＴＮの軸方向長さを小さく形成することができ、全体の外形寸法を小さく構成することができる。このため、クラックが近接して複数ある場合でも前記接着剤注入器１００を鑑賞させずに設けやすい。また、加圧や解圧するために前記蓄圧機構ＴＮの先端側に別の工具や器具を取り付ける必要がないので、前記接着剤注入器１００が近接して設けられている場合でも加圧や解圧の作業を行いやすい。 Further, since the lid body 6 has a double pipe structure and the positions of the outer cylinder 62 gripped by the user and the inner plug body 61 in the axial direction can be substantially the same, the pressure accumulator mechanism TN The axial length of the lid can be made small, and the overall external dimensions can be made small. Therefore, even if there are a plurality of cracks in close proximity to each other, it is easy to provide the adhesive injector 100 without viewing it. Further, since it is not necessary to attach another tool or instrument to the tip end side of the accumulator mechanism TN in order to pressurize or depressurize, even when the adhesive injector 100 is provided in close proximity, pressurization or depressurization is performed. Easy to do the work of.
本発明のその他の実施形態について説明する。 Other embodiments of the present invention will be described.
螺合構造７については前記中空筒４と前記蓋体６との間に設けられていればよく、中空筒４の内側周面に雌ねじ７２が形成され、蓋体６の中栓体６１の外側周面に雄ねじ７１を形成するようにしてもよい。また、中栓体６１による気密性をより向上させるために中栓体６１の内側端にパッキンを設けてもよい。 The screw structure 7 may be provided between the hollow cylinder 4 and the lid 6, and a female screw 72 is formed on the inner peripheral surface of the hollow cylinder 4 to form an outer plug body 61 of the lid 6. A male screw 71 may be formed on the peripheral surface. Further, a packing may be provided at the inner end of the inner plug body 61 in order to further improve the airtightness of the inner plug body 61.
前記蓋体６については、かならずしも二重管構造を有するものでなくてもよく、例えば中栓体の外側端からさらに外側に突出するようにユーザにより蓋体６を回転させるために把持される把持部を形成しても構わない。 The lid 6 does not necessarily have a double-tube structure, for example, a grip held by the user to rotate the lid 6 so as to project further outward from the outer end of the inner plug. A part may be formed.
前記蓄圧機構ＴＮは、前記注入機構ＩＮに対して直交して設けられたものでなく、斜めに取り付けられるものであってもよい。要するに、前記注入機構ＩＮから分岐して前記蓄圧機構ＴＮが設けられるものであればよい。また、前記蓄圧機構ＴＮを構成する前記中空筒４の形状は円筒管形状のみに限られるものではない。例えば、前記中空筒４を基端側が先端側よりも細い二段円筒形状にしてもよい。このようなものにすれば、前記注入機構ＩＮに対して前記中空筒４が突出している長さ寸法を短くして接着剤注入器１００自体をコンパクトに構成することができる。しかも、前記蓋体６が取り付けられる際に中空筒４内に押し込む気体の体積も大きくできるので、前記実施形態と同等又はそれ以上に前記中空筒４内の気体を予圧しておくこともできる。 The pressure accumulator mechanism TN is not provided orthogonally to the injection mechanism IN, but may be mounted diagonally. In short, it suffices that the pressure accumulator mechanism TN is provided by branching from the injection mechanism IN. Further, the shape of the hollow cylinder 4 constituting the accumulator mechanism TN is not limited to the shape of a cylindrical tube. For example, the hollow cylinder 4 may have a two-stage cylindrical shape in which the base end side is thinner than the tip end side. With such a structure, the adhesive injector 100 itself can be compactly configured by shortening the length dimension in which the hollow cylinder 4 protrudes from the injection mechanism IN. Moreover, since the volume of the gas pushed into the hollow cylinder 4 when the lid 6 is attached can be increased, the gas in the hollow cylinder 4 can be preloaded as much as or more than that of the embodiment.
前記実施形態では補修対象はクラックＡＯであったが、その他の補修対象に本発明を用いても構わない。また、流動性補修材の一例として接着剤Ｌを挙げたが、例えば、コーキング材等のその他のものにも本発明の流動性補修材注入器は用いることができる。また、流動性補修材供給源はグリスガンに限られるものではなく、例えばシリンジ等により人力で補修対象内に流動性補修材を注入するようにしてもよい。 In the above embodiment, the repair target is the crack AO, but the present invention may be used for other repair targets. Further, although the adhesive L is mentioned as an example of the fluidity repair material, the fluidity repair material injector of the present invention can also be used for other materials such as caulking material. Further, the source of the fluid repair material is not limited to the grease gun, and the fluid repair material may be manually injected into the repair target by, for example, a syringe or the like.
その他、本発明の趣旨に反しない限りにおいて様々な変形や実施形態の組み合わせを行っても構わない。 In addition, various modifications and combinations of embodiments may be made as long as it does not contradict the gist of the present invention.
