Description

콘크리트구조물의 균열보수용 패커{Device for concrete crack repair}Device for concrete crack repair packer

본 고안은 콘크리트구조물의 균열시 접착 및 강화시키기 위해 사용되는 패커(PACKER)에 관한 것으로서, 더욱 상세하게는 콘크리트구조물의 균열된 부분을 보다 신속하고 완벽하게 보수할 수 있도록 개선된 콘크리트구조물의 균열보수용 패커에 관한 것이다.The present invention relates to a packer (PACKER) used to bond and reinforce when the concrete structure cracks, more specifically crack repair of the improved concrete structure to more quickly and completely repair the cracked portion of the concrete structure It is about a dragon packer.

일반적으로 콘크리트구조물에 균열이 발생하면 그 균열된 부분에 설치용 구멍을 뚫은 다음 패커를 구멍에 설치하고 접착 작용을 하는 약품용액을 주입하는 방법이 실시되고 있다.In general, when a crack occurs in a concrete structure, a hole is installed in the cracked portion, and then a packer is installed in the hole and a chemical solution injecting the adhesive is applied.

따라서, 패커는 콘크리트구조물의 균열 부분을 보수하는데 필수적인 장치라고 할 수 있으며, 약품용액을 주입하기 위한 주입파이프와, 상기 주입파이프를 통해 주입된 약품용액이 다시 역류되는 것을 차단하기 위한 볼첵크밸브와, 주입파이프와 설치구멍(이하 콘크리트구멍이라고도 함)의 틈새로 약품용액이 흘러 나오는 것을 차단하기 위한 고무슬리브부재와, 상기 고무슬리브부재가 콘크리트구멍 내벽에 밀착되도록 하기 위해 주입파이프와 함께 설치되는 라체트 등을 구비하는 구조로 되어 있다.Therefore, the packer can be said to be an essential device for repairing the cracked part of the concrete structure, an injection pipe for injecting a chemical solution, a ball check valve for blocking back flow of the chemical solution injected through the injection pipe, and And a rubber sleeve member for blocking the flow of the chemical solution into the gap between the injection pipe and the installation hole (hereinafter referred to as concrete hole), and the rubber sleeve member installed together with the injection pipe to keep the rubber sleeve member in close contact with the inner wall of the concrete hole. It has a structure provided with a check or the like.

그러나 이러한 선행기술의 패커는 고무슬리브부재를 압축시키기 위하여 주입파이프를 조임 유격까지 조여 주어야 하는 과정이 번거롭고 시간이 오래 걸리므로써 패커 설치 작업성이 나쁘고 시공 시간이 오래 걸리는 등의 결점이 있다.However, the packer of the prior art has a drawback in that the process of tightening the injection pipe to the tightening clearance to compress the rubber sleeve member is cumbersome and takes a long time, so that the packer installation workability is poor and the construction time is long.

또한, 선행기술의 패커는 균열 보수 작업이 완료되면 패커를 콘크리트구멍으로부터 다시 빼내야 하는 것이기 때문에 패커가 제거된 콘크리트구멍으로부터 균열 보수를 위해 투입되었던 약품용액이 다시 흘러 나와 누수되고 약품용액의 손실이 따르는 등의 문제점이 있을 뿐만 아니라 균열 보수 작업 완료후 패커를 일일이 제거해야 하므로 불편하고 번거로운 문제점을 수반하고 있다.In addition, the packer of the prior art is to remove the packer from the concrete hole when the crack repair work is completed, so that the chemical solution that was introduced for crack repair flows out of the concrete hole from which the packer is removed and leaks, resulting in a loss of the chemical solution. In addition to the problems, such as the need to remove the packer after the crack repair work is accompanied by inconvenience and cumbersome problems.

더욱이, 선행기술의 패커는 통상의 볼첵크밸브를 채용하여 주입된 약품용액이 외부로 역류되지 않도록 차단하는 구조를 가지고 있다. 그러나 이러한 볼첵크밸브 구조는 정밀하게 가공되어야 만이 볼이 약품용액 주입공을 막아서 차단할 수 있게 된다. 그러므로 정밀한 연마 가공이 요구되는데 약품용액 주입공과 볼 자체의 직경이 작으므로 정밀한 연마가공이 난이할뿐 아니라 가공비가 비싸므로 원가상승이 초래되고 가공 불량률이 높아서 역류 방지 기능을 제대로 발휘하지 못하고 주입된 약품용액이 역류되어 누수되는 등의 문제점을 수반하고 있다.Moreover, the packer of the prior art has a structure which blocks the injected chemical solution from flowing backward by employing a conventional ball check valve. However, the ball check valve structure must be precisely processed so that the ball can be blocked by blocking the chemical solution injection hole. Therefore, precise grinding process is required. Because the diameter of chemical solution injection hole and ball itself is small, precise grinding process is not only difficult, but also expensive processing cost, which leads to cost increase and high processing defect rate. It is accompanied with the problem that a solution flows backward and leaks.

본 고안은 상기한 바와 같은 종래의 제반 문제점을 감안하여, 패커 설치가 신속하면서도 주입된 약품용액이 역류되지 않는 패커를 제공하려는데 그 주된 목적이 있다.The present invention has been made in view of the above-mentioned problems in the related art, and provides a packer in which a packer is installed quickly but the injected chemical solution does not flow back.

본 고안의 다른 목적은, 균열 보수 완료후 콘크리트구멍으로부터 패커 일부만 제거한 후 마감 처리할 수 있는 패커를 제공함으로써 시공 완료후 주입된 약품용액이 누수되지 않게 하고 완벽한 균열 보수가 도모되도록 하려는데 있다.Another object of the present invention is to provide a packer that can be finished after removing only a portion of the packer from the concrete hole after the completion of the crack repair to prevent leakage of the injected chemical solution and complete crack repair.

상기한 목적을 달성하기 위한 본 고안은, 약품용액을 주입시키기 위한 주입기가 연결되는 니플부와 상기 니플부와 길이 방향으로 일체로 연장된 주입파이프부와 약품용액이 투입되는 약품주입공을 가진 주입부재와, 상기 주입파이프부에 결합되어 약품용액 누수를 차단하기 위해 콘크리트구멍 내벽에 압축되어 밀착되는 고무슬리브부재를 갖는 패커에 있어서; 상기 고무슬리브부재를 압축시키기 위해 주입부재 상단부 양측에 각각 갖는 걸림로드와; 상기 걸림로드가 전,후방향으로 이동 가능한 관통홈부와, 상기 관통홈부와 직각된 위치에 형성되고 걸림로드가 90°회전하여 걸리게 되는 로크홈부를 상면부에 가지며 상기 관통홈부에 걸림로드가 삽입되도록 주입파이프부가 끼워지는 결합공을 갖는 로크헤드와; 상기 로크헤드와 밀접되게 결합되는 고무슬리브부재를 압축시키기 위해 주입파이프 후단부에 형성된 나사부에 체결되는 너트부재와; 상기 나사부가 있는 주입파이프부 후단부에 구비하는 핀공내에서 전,후이동되고 탄력부재의 탄력을 받으며 약품주입공에 삽입되는 핀부와 핀공내에 위치하는 핀본체부 사이에 끼워져서 약품주입공을 밀폐시키는 역류방지용 오링부재를 갖는 핀밸브에 의해형성되는 밸브부를 포함하여 구성됨을 그 특징으로 한다.The present invention for achieving the above object, the injection having a nipple portion connected to the injector for injecting a chemical solution and the injection pipe portion and the chemical injection hole into which the medicine solution is integrally extended in the longitudinal direction A packer having a member and a rubber sleeve member coupled to the injection pipe part and pressed against the inner wall of the concrete hole to block leakage of the chemical solution; Hooking rods each having both sides of an upper end portion of an injection member to compress the rubber sleeve member; The locking rod has a through groove portion which is movable in the front and rear directions, and a lock groove portion formed at a position perpendicular to the through groove portion, and having a locking groove portion which is caught by rotating the locking rod by 90 ° on the upper surface thereof so that the locking rod is inserted into the through groove portion.

도 2를 참조하면, 본 고안의 패커(1)는 주입부재(2)에 로크헤드(30)와 고무슬리브부재(20)가 결합된 후 너트부재(40)가 체결되어 하나의 장치가 된다. 이러한 패커(1)에 있어서 고무슬리브부재(20)는 압축되지 아니한 본래의 길이(L) 상태를 가진다. 이 상태에서 균열된 콘크리트구조물에 뚫어 놓은 콘크리트구멍(H)에 삽입된다.Referring to FIG. 2, the packer 1 of the present invention has a lock head 30 and a rubber sleeve member 20 coupled to the injection member 2, and then a nut member 40 is coupled to one device. In this packer 1, the rubber sleeve member 20 has an original length L state which is not compressed. In this state is inserted into the concrete hole (H) drilled in the cracked concrete structure.

이때, 걸림로드(7)는 로크헤드(30)의 관통홈부(32)의 하측에 위치하는 상태에 있게 된다.At this time, the locking rod 7 is in a state located below the through groove 32 of the lock head 30.

이 상태에서 로크헤드(30)를 누른 상태에서 주입부재(2)를 도 3에 보인 바와 같이 앞쪽으로 당긴 다음 도 4에 보인 바와 같이 90° 회전시켜서 놓게 되면 걸림로드(7)가 로크헤드(30)의 로크홈부(33)에 안착된다. 이와 같은 조작에 의해서 너트부재(40)는 앞쪽으로 이동되고, 그로인해 너트부재(40)와 로크헤드(30) 사이에 있는 고무슬리브부재(20)는 그 길이가 도 5와 같이 압축된 길이(La)가 된다.In this state, when the injection member 2 is pulled forward as shown in FIG. 3 while the lock head 30 is pressed and then rotated by 90 ° as shown in FIG. 4, the locking rod 7 is locked by the lockhead 30. It is seated in the lock groove 33 of. By this operation, the nut member 40 is moved to the front, whereby the rubber sleeve member 20 between the nut member 40 and the lock head 30 has a length that is compressed as shown in FIG. La).

따라서, 압축 작용되는 고무슬리브부재(20)는 부피가 외주면 방향으로 밀려 나게 되므로 콘크리트구멍(H)의 내벽에 밀착되는 상태가 되고, 그로인해 주입된 약품용액이 외부로 누수되는 것을 차단하게 된다.Therefore, the rubber sleeve member 20 to be compressed acts to be in close contact with the inner wall of the concrete hole H since the volume is pushed toward the outer circumferential surface, thereby preventing the injected chemical solution from leaking to the outside.

이 상태에서 도 5에 보인 바와 같이 주입기(P)를 이용하여 니플부(3)의 약품주입공(5)을 통해 약품용액을 주입한다. 이때 약품용액은 주입 압력을 가지며, 이러한 주입 압력에 의해 핀밸브(12)는 후측으로 밀려 나게 된다. 따라서 약품용액은 원만한 주입이 된다.In this state, as shown in FIG. 5, the chemical solution is injected through the chemical injection hole 5 of the nipple part 3 using the injector P. At this time, the chemical solution has an injection pressure, and by this injection pressure, the pin valve 12 is pushed to the rear side. Thus, the drug solution is a smooth injection.

한편, 약품용액의 주입을 잠시 중단하거나 또는 완료하였을때는 약품용액의 주입압력이 상실되는 상태이다. 이때는 탄력부재(13)의 탄력이 핀밸브(12)에 작용됨으로써 그 핀밸브(12)가 앞쪽으로 이동된다. 그리고 핀밸브(12)가 가지고 있는 역류방지용 오링부재(14)가 약품주입공(5)을 밀폐시키게 되며, 이 역류방지용 오링부재(14)는 고무재질로 되어 있어 탄력을 보유하고 있기 때문에 틈새 발생이 전혀 없이 약품주입공(5)을 밀폐시키게 되므로 내부로 주입된 약품용액이 다시 약품주입공(5)을 통해서 외부로 누출되는 역류가 전혀 발생하지 않게 된다.On the other hand, when the injection of the chemical solution is temporarily stopped or completed, the injection pressure of the chemical solution is lost. At this time, the elasticity of the elastic member 13 is applied to the pin valve 12, the pin valve 12 is moved to the front. In addition, the backflow preventing O-ring member 14 of the pin valve 12 seals the chemical injection hole 5, and the backflow preventing O-ring member 14 is made of rubber material to retain elasticity. Since the drug injection hole (5) is sealed without this at all, the drug solution injected into the inside again does not occur at all through the drug injection hole (5).

한편, 약품용액 주입 작업이 완료되면 최종으로 니플부(3)를 제거한다. 제거 방법은 도 6에 보인 바와 같이 니플부(3)를 햄머와 같은 도구에 의해서 타격한다. 이때 타격력에 의해서 커트홈부(6)가 절단됨으로써 니플부(3)가 제거되는 것이다.On the other hand, when the chemical solution injection operation is completed, the nipple portion (3) is finally removed. The removal method strikes the nipple part 3 with a tool such as a hammer as shown in FIG. At this time, the cut groove portion 6 is cut by the striking force, so that the nipple portion 3 is removed.

이 상태에서는 콘크리트구멍(H) 외부로는 전혀 노출되는 것이 없다. 또한, 밸브부(10)와 고무슬리브부재(20)에 의해서 주입된 약품용액은 전혀 누출되지 않게 되어 있는 상태이다. 그러므로 니플부(3) 제거후에 그 즉시 콘크리트구멍(H)을 마감 처리할 수 있게 된다.In this state, nothing is exposed to the outside of the concrete hole H at all. In addition, the chemical solution injected by the valve unit 10 and the rubber sleeve member 20 is in a state of not leaking at all. Therefore, it is possible to finish the concrete hole (H) immediately after removing the nipple portion (3).

참고적으로, 종전에는 약품용액의 주입 작업 종료후 최소한 24시간 경과 후에 패커를 콘크리트구멍으로부터 제거한 후 마감 처리하여야 함으로써 작업시간이 오래 걸리고 인건비가 많이 들어 가는 등의 문제와 더불어서 패커 전체를 콘크리트구멍으로부터 완전히 제거함에 따라 약품용액이 다시 흘러 나오게 되는 등의 하자발생률이 높은 문제가 있었는 바, 본 고안은 패커(1)가 주입 작업 종료후 니플부(3)만 제거하고 마감 처리하므로 신속한 작업 완료 및 그에따른 인건비 절감을 도모하게 되고 패커 자체가 콘크리트구멍 내에 그대로 존재하게 되므로 작업 완료후에도 주입된 약품용액이 절대로 외부로 누출되는 일이 없게 되므로 콘크리트 균열 보수 및 보강에 있어 완벽한 시공이 도모되게 되는 것이다.For reference, in the past, at least 24 hours after the end of the injection of chemical solution, the packer should be removed from the concrete hole and finished, and the entire packer may be removed from the concrete hole. There was a problem that the defect rate is high, such as the chemical solution flows out again as completely removed, the present invention is because the packer (1) removes only the nipple (3) after finishing the injection operation and finishes the process quickly and thus The labor cost is reduced and the packer itself remains in the concrete hole so that the injected chemical solution never leaks to the outside even after the work is completed, thereby perfecting the construction of the concrete crack repair and reinforcement.

이상의 설명에 따르면, 본 고안의 패커는 설치에 있어 주입부재를 잡아 당긴 후 반회전시켜 걸림로드가 로크헤드에 걸리도록 하면 되므로 보다 신속하고도 간편하게 패커를 설치할 수 있는 효과를 제공한다.According to the above description, the packer of the present invention has the effect of being able to install the packer more quickly and simply because the locking rod is pulled to the lock head by pulling the injection member and then rotating it halfway.

또한, 핀밸브와 역류방지용 오링부재를 가진 밸브부를 가짐으로써 주입된 약품용액의 역류 방지를 완벽하게 수행하게 되므로 제품 신뢰성 및 약품용액의 절감 효과를 제공할뿐 아니라 주입 작업 완료후 니플부 제거만으로 즉시 마감 처리할 수 있으므로 시공시간 단축 및 인건비 절감 등의 효과를 가지게 되는 유용한 고안이다.In addition, it has a valve valve with a pin valve and an O-ring member to prevent backflow, which completely prevents the backflow of the injected chemical solution, thus providing product reliability and reducing the chemical solution, and immediately removing the nipple after completion of the injection operation. Because it can be finished, it is a useful design that has the effect of reducing construction time and labor cost.
