본 고안은 콘크리트 구조물의 벽면, 바닥 또는 천정에 발생된 크랙의 보수를 위하여 콘크리트 크랙 보강약액을 주입시키는 주입장치에 관한 것으로, 특히 본 고안은 원통형케이스 전방내측에서 삽입되는 내케이스의 전단을 원통형 케이스 전방으로 돌출되게 결합하는 구성으로 콘크리트 크랙 보강약액을 내케이스에 신속하게 충전시키기 위해 내케이스의 전단 나사부에서 노즐부가 일체로 형성된 전방캡을 나사식으로 풀어서 분리하고 이어서 보강약액 용기를 기울려 보강약액을 내케이스에 부어줄 때 및 보강약액을 다붓고 보강약액용기를 똑바로 세울 때 보강약액이 원통형 케이스에 묻게 되는 폐단을 방지하여 원통형 케이스의 재 사용수명을 현저하게 연장 시킬 수 있도록 하기 위하여 본인이 선출원한 실용신안등록출원 제87-18156호를 개량한 것이다.The present invention relates to an injection device for injecting concrete crack reinforcing chemicals for repair of cracks generated on the wall, floor, or ceiling of a concrete structure. In order to fasten the concrete crack reinforcement chemical to the inner case in a conjoined forward configuration, the front cap formed by the nozzle unit is unscrewed and separated from the front end screw portion of the inner case, and then the reinforcement liquid container is tilted to remove the reinforcement chemical. When pouring into the inner case, pouring the reinforcing chemicals and uprighting the reinforcing liquids container, prevent the closed end of the reinforcing liquids from the cylindrical case so that the life of the cylindrical case can be remarkably extended. Improvement of Utility Model Application No. 87-18156 The.
본 고안의 개량된 점을 구체적으로 설명하면 내케이스의 외주면에 후렌지를 환설하되, 이 후렌지의 위치를 전방측으로 편중시켜 형성함과 동시 후렌지후측에 결합나사부를 형성하여 원통형 케이스 전단 내측의 나사부에 전기의 결합나사부가 맞물려지도록 하여 후렌지의 뒤쪽인 내케이스의 긴 후단부는 원통형 케이스 전단측 내주면에 밀착된 상태로 삽입, 결합되게 하고, 후렌지의 앞쪽인 내케이스의 전단부는 원통형 케이스 전방으로 돌출된 상태가 되게 하여 그 돌출된 전단부에 형성한 나사부에 전방캡을 나사조립 시키도록 하였다.In detail, the improved point of the present invention is to replace the flange on the outer circumferential surface of the inner case, and the position of the flange is biased to the front side, and at the same time, the coupling screw portion is formed on the rear side of the flange to provide the screw part inside the cylindrical case front end. Of the inner case, which is the rear side of the flange, is inserted and coupled in a state of being in close contact with the inner circumferential surface of the cylindrical case front side, and the front end of the inner case which is the front of the flange protrudes toward the front of the cylindrical case. The front cap was screwed to the threaded portion formed at the protruding front end portion thereof.
따라서 내케이스 전단나사부에 나사조립된 전방캡을 풀어 분리한 다음, 보강약액용기에 들어 있는 보강약액을 내케이스에 부을 때 취급자의 부주의에 의해 내케이스 전단부 외주면에 소량의 보강약액이 묻어 흘러내리더라도 내케이스 전단부측 외주면에 환설된 후렌지가 원통형 케이스로 보강약액이 흐르는 것을 방지하여 주므로서 원통형 케이스에는 보강약액이 묻게 되는 폐단이 발생되지 않아 원통형 케이스 자체를 효과적으로 재 사용할 수 있게 되는 것이다.Therefore, remove the front cap screwed in the inner case shear screw part, separate it, and then, when the reinforcing liquid contained in the reinforcing chemical container is poured into the inner case, a small amount of reinforcing liquid will flow on the outer circumference of the inner case front part due to the carelessness of the operator. Even if the Hurenji circumscribed on the outer peripheral surface of the inner casing front side prevents the reinforcing chemical from flowing into the cylindrical case, the closed case in which the reinforcing chemical is buried does not occur in the cylindrical case, thereby effectively reusing the cylindrical case itself.
종래 콘크리트 크랙을 보수하는 보강약액 주입장치로서 콘크리트 구조물에 발생된 크랙의 크기에 따라 보강약액의 주입 압력을 선택, 조절할 수 있도록 탄발력이 약한 스프링과 탄발력이 강한 스프링을 스프링 규제링 양측에 대설하는 상태로 원통형 케이스 내측에 설치한 본인의 실용신안등록출원 제87-18156호로서 제 4 도의 (a)(b)도와 같은 주입장치가 있었다.As a reinforcement chemical injection device for repairing conventional concrete cracks, springs with weak elasticity and springs with strong elasticity are installed on both sides of the spring regulating ring to select and adjust the injection pressure of the reinforcing chemical according to the size of the crack generated in the concrete structure There was an injection device as shown in Fig. 4 (a) and (b) of Utility Model Registration Application No. 87-18156, which was installed inside the cylindrical case.
그러나 상기의 주입장치(100)는 원통형 케이스(101) 전방 내측으로 나사부(102')가 있는 후렌지(102)를 형성한 내케이스(103)를 삽입하되, 후렌지(102)가 원통형 케이스(101) 전단 둘레부에 밀착된 상태로 하여 나사부(102')의 피치가 원통형 케이스(101)의 전단나사부(101')의 피치가 일치하도록 구성하여 전방캡(104)이 후렌지(102)의 나사부(102')와 원통형 케이스(101)의 전단나사부(101')를 동시에 나사조립되게 하는 구성으로 되어있다.However, the injection device 100 is inserted into the inner case 103 formed with a flange 102 with a threaded portion 102 'inside the cylindrical case 101, but the flange 102 is a cylindrical case 101. The front cap 104 of the flange 102 of the flange 102 is configured such that the pitch of the threaded portion 102 'coincides with the pitch of the sheared threaded portion 101' of the cylindrical case 101 while being in close contact with the front end portion. ') And the shear screw portion 101' of the cylindrical case 101 are configured to be screwed at the same time.
그런데 상기와 같은 종래의 주입장치(100)에 보강약액(W)을 주입하기 위해서는 제 4 도의 (a) 도와 같이 스프링규제링(105)양측에 대치상으로 탄력설치한 탄발력이 강한 스프링(106)과 탄발력이 약한 스프링(107)의 탄발력에 의해 피스톤판체(108)의 전단에 나사 결합된 고무제 피스톤(109)이 전방캡(104)내면에 밀착된 상태로 위치시킨 다음, 전방캡(104)의 노즐부(104')를 보강약액용기(T)에 투입하여 견인링(110)을 잡아당기는 작업으로 고무제 피스톤(109)을 후방으로 이동시키는 흡입작용으로 보강약액(W)을 내케이스(103)내측으로 흡입시켜 왔었으나, 이러한 작업은 힘이 들고 충전작업이 신속하지 못한 문제점이 있기 때문에 제 4 도의 (b)도와 같이 고무제피스톤(109)을 후방으로 이동시켜 고정시킨 다음 전방캡(104)을 풀어 해체하고 보강약액용기(T)에 들어 있는 보강약액(W)을 내케이스(103)로 부어 충전시키는 작업의 채택으로 충전작업을 신속하게 수행하는 방법을 채택하여 왔었는바, 이러한 충전방법은 간편하고 신속한 이점이 있으나, 보강약액(W)을 붓는 취급자의 부주의한 동작으로 보강약액(W)을 밖으로 흘릴 경우에는 내케이스(103)의 후렌지(102)가 원통형 케이스(101) 전단둘레부에 밀착된 상태이기 때문에 보강약액(W)이 원통형 케이스(101) 외주면에 묻게 되는 사례가 종종발생되는바, 이와같이 보강약액(W)이 밖으로 흘러 내려 원통형 케이스(101)의 전단나사부(101')에 묻어있는 상태에서 전방캡(104)을 나사조립하고 콘크리트 크랙을 보수할 경우에는 전단나사부(101')에 묻어있는 보강약액(W)에 의해 전방캡(104)이 전단나사부(101')에 접착된 상태가 되므로서 보수작업완료후 원통형 케이스(101)와 전방캡(104)을 분리할 수 없게 되어 소모품이 아닌 원통형 케이스(101)자체도 소모품화 하는 결점이 있었다.However, in order to inject the reinforcing chemical solution (W) into the conventional injection device 100 as described above, as shown in FIG. 4 (a), spring-loaded springs with strong elasticity installed in opposite directions on both sides of the spring regulating ring 105. ) And the rubber piston 109 screwed to the front end of the piston plate body 108 by the elastic force of the spring 107 having a weak elastic force is placed in close contact with the inner surface of the front cap 104, and then the front cap The nozzle portion 104 'of the 104 is inserted into the reinforcing chemical container T to pull the towing ring 110, and the reinforcing chemical liquid W is moved by the suction action of moving the rubber piston 109 backward. It has been sucked into the inner case 103, but this operation is difficult and the filling operation is not fast, so as to move the rubber piston 109 to the rear as shown in Figure 4 (b) and then fixed Loosen and dismantle the front cap 104 and reinforce the chemical container (T). The method of filling the liquid (W) into the inner case 103 has been adopted by the method of quickly filling the bar, this filling method has a simple and quick advantage, but pouring the reinforcing chemical (W) When the reinforcing chemical liquid W flows out due to the careless operation of the operator, since the flange 102 of the inner case 103 is in close contact with the front circumference of the cylindrical case 101, the reinforcing chemical liquid W is a cylindrical case ( 101) Often the case is buried on the outer circumferential surface, the reinforcing liquid (W) flows out in this way, while the front cap 104 is screwed in the state of being buried in the shear screw portion (101 ') of the cylindrical case 101 and concrete When repairing the crack, the cylindrical case 101 is completed after the repair work is completed because the front cap 104 is adhered to the shear screw portion 101 'by the reinforcing chemical liquid W buried in the shear screw portion 101'. And front cap (104) It is not cylindrical case 101, a non-consumable had the drawback that also supplies screen itself.
본 고안은 상기와 같은 결점사항을 감안하여 주입장치에 보강약액을 보다 신속하게 주입시킴에 있어 보강약액이 원통형 케이스에는 절대 묻게되는 사례를 방지하여 콘크리트 크랙 보수작업 완료후 원통형 케이스를 원형그대로 회수하여 재사용이 가능토록 한 것으로, 이를 첨부한 도면에 따라서 상세히 설명하면 다음과 같다.The present invention prevents the case where the reinforcing chemical is never buried in the cylindrical case in order to inject the reinforcing chemical into the injection device more quickly in consideration of the above-mentioned defects, and recovers the cylindrical case as it is after the completion of the concrete crack repair work. It is possible to reuse, and described in detail according to the accompanying drawings as follows.

Next, when the reinforcing chemical solution (W) contained in the reinforcing liquid container 20 is poured, the reinforcing chemical liquid (W) can be quickly filled in the inner case 14, and a small amount of reinforcing liquid ( W) overflows to the outside of the front portion 14 "of the inner case 14 or reinforces the chemical W Pour it and pour the outer circumference when it flows down the outer circumference of the front part (14 ") of the small amount of reinforcement liquid when the reinforcing liquid container (20) is straightened. The small amount of reinforcing chemical liquid (W) is prevented from flowing to the cylindrical case (1) by the flange 15, even if the reinforcement overflowed over the flange 15 even if a large amount of reinforcing liquid is not prevented from flowing as the flange 15. Since the chemical liquid flows on the outer surface of the shear protrusion circumference 13 of the cylindrical case 1, the case where the absolute reinforcing chemical liquid is buried in the shear screw portion 1 'can be prevented. Even if the inner case 14, the front cap 2 and the rubber piston 4 which are in contact with each other are replaced with new ones, the cylindrical case 1 and the piston body and the two springs 9 and 11 that are weak and strong in elasticity are It can be reused.
이와 같은 본 고안은 원통형 케이스 자체를 재사용이 가능토록 하기 위해 원통형 케이스 전방 내측에 내케이스를 끼워 설치하고, 내케이스에 보강약액의 주입충전작업을 보다 신속하게 수행하기 위해 전방캡을 열고 보강약액을 붓는 작업시 취급자의 부주의 등으로 인하여 보강약액이 내케이스를 넘쳐 흐르는 현상에 의해 원통형 케이스 자체를 못쓰게 되는 사례를 방지할 수 있으므로서 주입장치의 주요부품인 원통형 케이스를 재사용할 수 있는 실용적인 고안인 것이다.The present invention is installed by inserting the inner case inside the front of the cylindrical case in order to enable the reuse of the cylindrical case itself, open the front cap to perform the filling and filling operation of the reinforcing chemical in the inner case more quickly It is a practical design that can reuse the cylindrical case, which is the main part of the injection device, because it prevents the case where the reinforcing chemical liquid overflows the inner case due to the carelessness of the handler during the pouring operation. .
