以下、本発明の実施形態に係る静的破砕剤注入用容器につき、図面を参照しつつ具体的に説明する。
図1は、静的破砕剤注入用容器の第一実施形態を示した断面図である。図1に示す如く、注入用容器1は、静的破砕剤Aを収容しうる胴部10と、該胴部10から突出して設けられ、先端付近に静的破砕剤Aを吐出するための吐出口11が形成された突出部12とを備え、さらに、胴部10に収容した静的破砕剤Aを加圧しうる加圧手段20とを備えてなる。
Hereinafter, the container for static crushing agent injection concerning the embodiment of the present invention is explained concretely, referring to drawings.

As shown in FIG. 1, an injection container 1 is provided with a barrel 10 that can accommodate a static crushing agent A and a protruding portion from the barrel 10, and a discharge for discharging the static crushing agent A near the tip. A projecting portion 12 having an outlet 11 formed thereon, and a pressurizing means 20 capable of pressurizing the static crushing agent A accommodated in the body portion 10.

具体的には、前記胴部10は有底の円筒形状に形成されており、その底面中央部には突出部12が該底面より略垂直に突出するように設けられている。また、底面に対向する位置には、筒状の胴部10に内接するピストン15が備えられており、該ピストン15は、胴部10に収容された静的破砕剤Aを密閉するとともに、前記筒状の胴部10内を軸方向に往復移動可能に取り付けられている。   Specifically, the body portion 10 is formed in a bottomed cylindrical shape, and a projecting portion 12 is provided at a center portion of the bottom surface so as to project substantially vertically from the bottom surface. In addition, a piston 15 inscribed in the cylindrical body 10 is provided at a position facing the bottom surface, and the piston 15 seals the static crushing agent A accommodated in the body 10, and The inside of the cylindrical trunk | drum 10 is attached so that a reciprocation is possible to an axial direction.

前記突出部12は、例えば、胴部10の底面(先端ともいう)から高さ1〜5cmとなるように構成され、好ましくは高さ2〜4cmとなるように構成される。   The protrusion 12 is configured to have a height of 1 to 5 cm, preferably 2 to 4 cm, from the bottom surface (also referred to as a tip) of the trunk portion 10, for example.

また、前記吐出口11は、突出部12の先端に設けられており、具体的には、その直径が0.1〜10mm、好ましくは0.2〜0.5mmの孔として形成されている。   Moreover, the said discharge outlet 11 is provided in the front-end | tip of the protrusion part 12, and specifically, it is formed as a hole whose diameter is 0.1-10 mm, Preferably it is 0.2-0.5 mm.

前記加圧手段20としては、本実施形態ではバネ機構を用いた例が記載されている。
具体的には、加圧手段20は、前記胴部10より径方向外側へ張り出した第一鍔部21と、前記ピストン15より径方向外側へ張り出した第二鍔部22と、該第一鍔部21と第二鍔部22とを連結するバネ23とを備えて構成されている。
即ち、本実施形態における加圧手段20は、静的破砕剤Aが胴部10内に収容されると前記第一鍔部21と第二鍔部22との間でバネ23が伸びた状態となり、第一鍔部21と第二鍔部22とを近づける方向に応力を発揮するよう構成されている。
As the pressurizing means 20, an example using a spring mechanism is described in the present embodiment.
Specifically, the pressurizing means 20 includes a first flange portion 21 projecting radially outward from the body portion 10, a second flange portion 22 projecting radially outward from the piston 15, and the first rod A spring 23 that connects the portion 21 and the second flange portion 22 is provided.
That is, in the pressurizing means 20 in the present embodiment, when the static crushing agent A is accommodated in the body portion 10, the spring 23 is extended between the first flange portion 21 and the second flange portion 22. The first collar 21 and the second collar 22 are configured to exert stress in a direction in which the first collar 21 and the second collar 22 approach each other.

該加圧手段20による静的破砕剤Aの加圧力は、該液の圧力が、0.001〜5N/mm2となるものが好ましく、0.005〜1N/mm2となるものがより好ましい。 Pressure static crushing agent A by pressurizing means 20, the pressure of the liquid is preferably made with 0.001~5N / mm 2, and more preferable to be 0.005~1N / mm 2 .

胴部10内に収容される静的破砕剤Aは、アルカリ加水分解反応によりカルボン酸を生成し、該カルボン酸のカルシウム塩が少なくとも結晶性である有機エステル化合物を有効成分とする液状のものである。   The static crushing agent A accommodated in the trunk | drum 10 produces | generates carboxylic acid by an alkaline hydrolysis reaction, and is a liquid thing which uses the organic ester compound whose calcium salt of this carboxylic acid is at least crystalline as an active ingredient. is there.

前記有機エステル化合物としては、セメント硬化体中においてアルカリ加水分解反応によってカルボン酸を生成し、該カルボン酸のカルシウム塩が結晶性であるものならば、何れも使用することができる。中でも、カルボン酸カルシウム塩の結晶が生成した際に、膨張圧の高いものが好ましい。
該有機エステル化合物の具体例としては、酢酸エチル、酢酸メチル、酢酸イソプロピル、アジピン酸ジエチル、セバシン酸2−エチルオキシル、アジピン酸ジイソブチル、アジピン酸ジイソプロピル等を挙げることができる。
Any organic ester compound may be used as long as it generates carboxylic acid by an alkaline hydrolysis reaction in a hardened cement body and the calcium salt of the carboxylic acid is crystalline. Among these, when a crystal of a calcium carboxylate is formed, one having a high expansion pressure is preferable.
Specific examples of the organic ester compound include ethyl acetate, methyl acetate, isopropyl acetate, diethyl adipate, 2-ethyloxyl sebacate, diisobutyl adipate, diisopropyl adipate and the like.

中でも、酢酸エチルや酢酸メチルを好適に使用することができ、酢酸エチルや酢酸メチルを用いた場合、静的破砕剤の浸透性が高くなるとともに、生成したカルボン酸カルシウム塩が水溶性で且つ結晶性のものであり、しかも生成時の膨張圧が高いという優れた効果がある。   Among them, ethyl acetate and methyl acetate can be preferably used.

斯かる構成の注入用容器1によれば、静的破砕剤Aの注入によってセメント硬化体Bの孔30にひび割れが生じた場合でも、固定手段40を介して張出部13がセメント硬化体B表面に密着固定されているため、注入用容器1の転倒や脱落を防止し、静的破砕剤Aの注入をより確実に行うことができる。
また、セメント硬化体Bと張出部13との密着により、孔30からの静的破砕剤Aの漏洩を防止しうるという効果もある。
特に、該張出部13が弾性部材によって構成されており、該胴部10から径方向外方へと直線状に延びた形状であれば、静的破砕剤Aの注入によってセメント硬化体Bが膨張した場合でも、該張出部13がその膨張に追従するように径方向外方へと伸張し、又は円周方向(左右)に変形されやすいため、注入用容器1の転倒及び脱落、並びに静的破砕剤Aの漏洩を防止できるという顕著な効果がある。
According to the injection container 1 having such a configuration, even when the crack 30 is generated in the hole 30 of the hardened cement body B due to the injection of the static crushing agent A, the overhanging portion 13 is connected to the hardened cement body B via the fixing means 40. Since it is tightly fixed on the surface, the injection container 1 can be prevented from falling and dropping, and the static crushing agent A can be injected more reliably.
In addition, due to the close contact between the hardened cement body B and the overhanging portion 13, there is an effect that leakage of the static crushing agent A from the hole 30 can be prevented.
In particular, if the overhanging portion 13 is formed of an elastic member and extends linearly outward from the body portion 10 in the radial direction, the cement hardened body B is injected by injection of the static crushing agent A. Even when it expands, the overhanging portion 13 extends radially outward so as to follow the expansion, or is easily deformed in the circumferential direction (left and right). There is a remarkable effect that leakage of the static crushing agent A can be prevented.

図4に示した注入用容器1は、突出部12の外周面に、該突出部12の径方向外方へと環状に張り出した断面山型の鍔部が軸方向に連続して形成された襞状部材18を備えたものである。該襞状部材18は、弾性を有する部材により構成されており、また、前記鍔部の直径はセメント硬化体Bの孔30よりも大径に形成されており、図4に示すように、該襞状部材18は、収縮させた状態で孔30に嵌入されるように構成されている。   The infusion container 1 shown in FIG. 4 has a mountain-shaped cross-sectional ridge that extends in an annular shape outwardly in the radial direction of the protrusion 12 on the outer peripheral surface of the protrusion 12. A bowl-shaped member 18 is provided. The flange-shaped member 18 is made of an elastic member, and the diameter of the flange is larger than the diameter of the hole 30 of the hardened cement body B. As shown in FIG. The hook-shaped member 18 is configured to be fitted into the hole 30 in a contracted state.

斯かる構成の注入用容器1によれば、襞状部材18によって孔30と突出部12とがより強固に接合した状態となるため、孔30からの静的破砕剤Aの漏洩が、より確実に防止されることとなる。
また、該襞状部材18が弾性を有する部材により構成され、収縮させた状態で孔30に嵌入されているため、孔30にひび割れが生じて孔の径が僅かに広がった場合でも、襞状部材18がこれに追従して膨張するため、孔30と突出部12との接合状態を維持でき、静的破砕剤Aの漏洩防止をより確実なものとし、注入用容器1の転倒及び脱落の防止にも寄与しうるという顕著な効果がある。
According to the injection container 1 having such a configuration, since the hole 30 and the protruding portion 12 are more firmly joined by the bowl-shaped member 18, the leakage of the static crushing agent A from the hole 30 is more reliable. Will be prevented.
In addition, since the hook-shaped member 18 is formed of an elastic member and is fitted into the hole 30 in a contracted state, even if the hole 30 is cracked and the diameter of the hole slightly increases, the hook-shaped member 18 Since the member 18 expands following this, the joined state between the hole 30 and the protruding portion 12 can be maintained, the leakage of the static crushing agent A can be more reliably prevented, and the injection container 1 can be overturned and dropped. There is a remarkable effect that it can also contribute to prevention.

図5に示した注入用容器1は、突出部12の周囲、及び胴部10の先端面に粘着材層19が設けられており、該粘着材層19を介して注入用容器1がセメント硬化体Bに固定されるものである。   The injecting container 1 shown in FIG. 5 is provided with an adhesive material layer 19 around the protruding portion 12 and the front end surface of the body portion 10, and the injecting container 1 is cement-cured through the adhesive material layer 19. It is fixed to the body B.

該粘着材層19を構成する材料としては、セメントとの粘着性が良好であり、静的破砕剤Aの有効成分である有機エステル化合物とは反応せず、しかも、高弾性を有するものが好ましい。具体的には、例えば、シリコンゴム、エポキシ樹脂、フェノール樹脂、ポリ塩化ビニリデン−塩化ビニル共重合体等を挙げることができる。   As the material constituting the pressure-sensitive adhesive layer 19, a material having good adhesion to cement, does not react with the organic ester compound which is an active ingredient of the static crushing agent A, and has high elasticity is preferable. . Specific examples include silicon rubber, epoxy resin, phenol resin, polyvinylidene chloride-vinyl chloride copolymer, and the like.

斯かる構成の注入用容器1によれば、粘着材層19によって注入用容器1とセメント硬化体Bとが密着状態に保たれるため、セメント硬化体Bの膨張による注入用容器1の転倒及び脱落、並びに静的破砕剤Aの漏洩を防止できるという顕著な効果がある。   According to the injection container 1 having such a configuration, since the injection container 1 and the hardened cement body B are kept in close contact with each other by the adhesive material layer 19, There is a remarkable effect that the falling off and leakage of the static crushing agent A can be prevented.

次に、本発明に係るセメント硬化体の破砕方法について、上記のような注入用容器を用いた場合について説明する。
即ち、本実施形態のセメント硬化体の破砕方法は、加圧手段20を備えた上記の如き注入用容器1内に静的破砕剤Aを充填するとともに、破砕対象となるセメント硬化体Bには、容器1の吐出部12を挿入するための孔30を形成する。
そして、該吐出口11を孔30に挿入した状態で注入用容器1をセメント硬化体Bに固定した後、加圧手段20による加圧力を作用させ、静的破砕剤Aを吐出口11から徐々に吐出させる。
Next, the case where the above injection container is used is demonstrated about the crushing method of the hardened cement body which concerns on this invention.
That is, according to the method for crushing a hardened cement body of the present embodiment, the static crushing agent A is filled in the injection container 1 having the pressurizing means 20 and the hardened cement body B to be crushed is used. The hole 30 for inserting the discharge part 12 of the container 1 is formed.
And after fixing the injection container 1 to the cement hardening body B in the state which inserted this discharge port 11 in the hole 30, the pressurizing force by the pressurizing means 20 is made to act, and the static crushing agent A is gradually discharged from the discharge port 11. To discharge.

斯かる方法により、静的破砕剤Aがセメント硬化体B中へと含浸されてゆくにつれて容器1からは新たな静的破砕剤Aが徐々に吐出されることとなり、容器内に充填された静的破砕剤Aの全量をセメント硬化体B中へと含浸させ、セメント硬化体Bを破砕することができる。   By such a method, as the static crushing agent A is impregnated into the cement hardened body B, a new static crushing agent A is gradually discharged from the container 1, and the static filling agent filled in the container is discharged. The entire amount of the mechanical crushing agent A is impregnated into the hardened cement body B, and the hardened cement body B can be crushed.

尚、本発明に係る静的破砕剤注入用容器は、上述のような実施形態に限定されるものではない。
例えば、前記実施形態では、加圧手段20としてバネを用いた例を説明したが、バネ以外にも、ゴム等の弾性体を用いて構成することも可能であり、また、気体の圧力を利用した構成を採用することも可能である。さらに、バネやゴム等の弾性体を用いることなくピストン自体の自重を利用して静的破砕剤を加圧する加圧手段であってもよい。
In addition, the container for static crushing agent injection | pouring which concerns on this invention is not limited to the above embodiments.
For example, in the above-described embodiment, an example in which a spring is used as the pressurizing unit 20 has been described. However, in addition to the spring, an elastic body such as rubber can be used, and a gas pressure is used. It is also possible to adopt the configuration described above. Further, it may be a pressurizing unit that pressurizes the static crushing agent using its own weight without using an elastic body such as a spring or rubber.

また、注入用容器1をセメント硬化体Bに固定する構成としては、上記実施形態を組み合わせて採用することも可能である。即ち、例えば、粘着材層19を備えるとともに張出部13を備え、固定手段40によって固定する構成としてもよい。
斯かる構成によれば、固定手段40によって張出部13がセメント硬化体Bへと押圧され、それによって粘着材層19が圧縮されるため、注入用容器1とセメント硬化体Bとの隙間を略完全に塞ぎ、静的破砕剤Aの漏洩をより確実に防止することができる。
Moreover, as a structure which fixes the container 1 for injection | pouring to the cement hardening body B, it is also possible to employ | adopt combining the said embodiment. That is, for example, the adhesive material layer 19 and the overhang portion 13 may be provided and fixed by the fixing means 40.
According to such a configuration, since the overhanging portion 13 is pressed against the hardened cement body B by the fixing means 40 and the adhesive material layer 19 is thereby compressed, the gap between the injection container 1 and the hardened cement body B is formed. It can be almost completely blocked, and leakage of the static crushing agent A can be prevented more reliably.

また、前記実施形態では、張出部13が胴部10から径方向外方へと直線状に延びた形状を有する場合について説明したが、これ以外にも、例えば図3(c)に示すように、胴部10と同心円である円形平板状に形成してもよい。   Moreover, although the said embodiment demonstrated the case where the overhang | projection part 13 had the shape extended linearly from the trunk | drum 10 to radial direction outward, in addition to this, as shown, for example in FIG.3 (c) Alternatively, it may be formed in a circular flat plate shape that is concentric with the body portion 10.

さらに、前記実施形態では、張出部をセメント硬化体へと固定する固定手段として釘やボルト等を用いる場合について説明したが、これ以外にも、例えば、張出部とセメント硬化体とを接着させる接着剤を用いてもよい。該接着剤としては、エポキシ樹脂系接着剤を挙げることができる。   Furthermore, in the above-described embodiment, the case where a nail, a bolt, or the like is used as a fixing means for fixing the overhang portion to the hardened cement body is described. However, for example, the overhang portion and the hardened cement body are bonded to each other. An adhesive to be used may be used. Examples of the adhesive include an epoxy resin adhesive.
