Abstract

PURPOSE: A manhole cover closed and fixed by a packing ring is provided to prevent the infiltration of the inside of a manhole with foreign matters and rainwater using a packing ring with improved sealing ability. CONSTITUTION: A connecting groove is formed along the upper inner circumference of a manhole frame(20). A packing ring(30) having a protruded fixing rib(31) is forcibly fitted in the connecting groove of the manhole frame. Two inclined portions(12) and fixing grooves(11) are formed on the outer circumference of a manhole cover(10). The fixing rib of the packing ring is inserted to the fixing grooves by elastically interlocking by the inclined portions.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 패킹링을 이용한 밀폐 및 고정형 맨홀뚜껑은, 맨홀프레임(20)의 상부 내주면을 따라 돌출된 고정리브(31)를 갖는 패킹링(30)이 억지끼움 되도록 결합홈(22)이 형성되고, 맨홀뚜껑(10)의 외주면에는 패킹링(30)의 고정리브(31)가 삽입되도록 경사부(12) 및 고정홈(11)이 형성된다.Sealed and fixed manhole cover using the packing ring according to the present invention for achieving the above object, the packing ring 30 having a fixing rib 31 protruding along the upper inner circumferential surface of the manhole frame 20 is interference fit. Coupling groove 22 is formed so that the inclined portion 12 and the fixing groove 11 is formed on the outer circumferential surface of the manhole cover 10 so that the fixing rib 31 of the packing ring 30 is inserted.
이하, 본 발명의 목적을 달성할 수 있는 바람직한 실시예의 기술구성 및 효과를 첨부된 도면을 참고하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings the technical configuration and effects of a preferred embodiment which can achieve the object of the present invention will be described.
도 1은 본 발명의 분리 사시도이고, 도 2는 본 발명의 밀폐 및 고정상태를 나타낸 절개 사시도이며, 도 3은 본 발명의 체결 과정을 나타낸 단면도이다.1 is an exploded perspective view of the present invention, Figure 2 is a cutaway perspective view showing a sealed and fixed state of the present invention, Figure 3 is a cross-sectional view showing a fastening process of the present invention.
도 1, 2에서 도시된 바와같이 맨홀뚜껑(10)의 외주면에는 경사부(12) 및 고정홈(11)이 형성되고, 맨홀프레임(20)의 하부 내부에는 맨홀뚜껑(10)이 안치될 수있는 안치턱(21)이 형성되며, 맨홀프레임(20)의 상부 내주면에는 탄성력을 가진 고무재질의 패킹링(30)이 억지끼움 되도록 결합홈(22)이 형성된다.1 and 2, the inclined portion 12 and the fixing groove 11 are formed on the outer circumferential surface of the manhole cover 10, and the manhole cover 10 may be placed inside the lower portion of the manhole frame 20. The settled jaw 21 is formed, and the coupling groove 22 is formed on the upper inner circumferential surface of the manhole frame 20 so that the packing ring 30 made of rubber material with elastic force is fitted.
상기 맨홀뚜껑(10)의 경사부(12)는 도 3에서와 같이 맨홀뚜껑(10)의 상단으로부터 하단으로 그 단면폭이 점차적으로 축소되는 2개의 경사부(12)로서, 맨홀프레임(20)에 설치된 패킹링(30)의 고정리브(31)에 자연스럽게 슬라이딩 되면서 장착되도록 구성한 것이다.The inclined portion 12 of the manhole cover 10 is two inclined portions 12 whose cross-sectional width is gradually reduced from the top to the bottom of the manhole cover 10, as shown in Figure 3, the manhole frame 20 It is configured to be mounted while naturally sliding to the fixed rib 31 of the installed packing ring 30.
도 3의 원내확대도와 같이 맨홀뚜껑(10)의 2개의 경사부(12) 사이에는 패킹링(30)의 고정리브(31)가 삽입되는 고정홈(11)이 형성되어 맨홀뚜껑(10)이 외부의 충격에 의해 이탈되지 않게 된다.As shown in the enlarged view of FIG. 3, between the two inclined portions 12 of the manhole cover 10, a fixing groove 11 into which the fixing rib 31 of the packing ring 30 is inserted is formed, and thus the manhole cover 10 is formed. It is not detached by an external shock.
상기 패킹링(30)의 고정리브(31)는 맨홀뚜껑(10)의 안착시에 경사부(12)에 의해서 탄성 연동되면서 고정홈(11)에 삽입되는 것으로서, 밀폐 및 고정 수단으로 사용된다.The fixing rib 31 of the packing ring 30 is inserted into the fixing groove 11 while being elastically interlocked by the inclined portion 12 when the manhole cover 10 is seated, and is used as a sealing and fixing means.
즉, 맨홀 내부로 이물질이나 우수의 침투를 방지하거나, 오수관용 맨홀의 경우 악취의 외부 발산을 방지하는 밀폐의 기능을 수행한다. 또한 외부충격으로부터 맨홀뚜껑(10)의 이탈을 방지하는 고정 기능을 수행한다.That is, it prevents the penetration of foreign matter or rainwater into the manhole, or in the case of the manhole for sewage pipe performs a function of sealing to prevent the external emanation of odor. In addition, the fixing function to prevent the departure of the manhole cover 10 from the external impact.
도 4는 본 발명에 인상링(40)이 추가 설치된 단면도이다. 여기서 인상링(40)이라함은, 도로 표면이 노후되면 노면 덧씌우기 공사를 하는바, 공사완료 후에는 종래의 맨홀뚜껑(10) 부위가 노면보다 함몰됨에 따라 이에 대한 높이 보정을 하고자 설치하는 구조물이다.4 is a cross-sectional view of the impression ring 40 is further installed in the present invention. Here, the impression ring 40 refers to a road overlay construction when the road surface is deteriorated. After completion of the construction, the structure is installed to correct the height of the manhole cover 10 after the construction is recessed than the road surface. to be.
상기 인상링(40)은 도 4에서 도시된 바와같이 인상링(40)의 하부 외부면에는맨홀프레임(20)에 억지끼움된 패킹링(30)에 의해서 밀착 고정되도록 2개의 경사부(43)와 고정홈(41)이 형성되고, 상부 내주면에는 탄성력을 가진 고무재질의 패킹링(30)이 억지끼움 되도록 결합홈(42)이 형성된다.The inclined ring 40 has two inclined portions 43 to be tightly fixed to the lower outer surface of the lifting ring 40 by a packing ring 30 that is pressed against the manhole frame 20, as shown in FIG. 4. And a fixing groove 41 is formed, and the coupling groove 42 is formed on the upper inner circumferential surface so that the packing ring 30 of rubber material with elastic force is fitted.
한편, 본 발명의 맨홀뚜껑(10)의 개방은 통상적으로 지렛대를 이용하여 억지개방 시킨다.On the other hand, the opening of the manhole cover 10 of the present invention is forcibly opened using a lever.
결국, 본 발명의 기술요지는 밀폐 및 고정형 맨홀뚜껑(10)에 있어서, 맨홀프레임(20)의 상부 내주면을 따라 결합홈(22)이 형성되고, 이 결합홈(22)에는 돌출된 고정리브(31)를 갖는 패킹링(30)이 억지끼움되며, 맨홀뚜껑(10)의 외주면에는 2개의 경사부(12)와 고정홈(11)이 형성되되, 상기 패킹링(30)의 고정리브(31)가 맨홀뚜껑(10)의 안착시에 경사부(12)에 의해서 탄성 연동되면서 고정홈(11)에 삽입됨을 특징으로 하는 패킹링을 이용한 밀폐 및 고정형 맨홀뚜껑이다. 또한 맨홀뚜껑(10)과 맨홀프레임(20)사이에 노면 덧씌우기 공사후 높이 보정을 위해 인상링(40)을 설치하되, 상기 인상링(40)은 하부 외부면에 맨홀프레임(20)에 억지끼움된 패킹링(30)에 의해서 밀착 고정되도록 2개의 경사부(43)와 고정홈(41)이 형성되고, 상부 내주면에는 돌출된 고정리브(31)를 갖는 패킹링(30)이 억지끼움 되도록 결합홈(22)이 형성된 것을 특징으로 하는 패킹링을 이용한 밀폐 및 고정형 맨홀뚜껑이다.As a result, the technical gist of the present invention, in the sealed and fixed manhole cover 10, a coupling groove 22 is formed along the upper inner circumferential surface of the manhole frame 20, the fixing groove (protruding fixed ribs) The packing ring 30 having the 31 is forcibly fitted, and two inclined portions 12 and fixing grooves 11 are formed on the outer circumferential surface of the manhole cover 10, and the fixing ribs 31 of the packing ring 30 are formed. ) Is a sealed and fixed manhole cover using a packing ring, which is inserted into the fixing groove 11 while being elastically interlocked by the inclined portion 12 when the manhole cover 10 is seated. In addition, although the impression ring 40 is installed between the manhole cover 10 and the manhole frame 20 for height correction after the road surface covering construction, the impression ring 40 is forced into the manhole frame 20 on the lower outer surface. Two inclined portions 43 and fixing grooves 41 are formed to be tightly fixed by the fitted packing ring 30, and the packing ring 30 having the protruding fixed ribs 31 is forcibly fitted on the upper inner circumferential surface thereof. It is a sealed and fixed manhole cover using a packing ring, characterized in that the coupling groove 22 is formed.
이상에서 살펴본 바와같이 본 발명인 패킹링을 이용한 밀폐 및 고정형 맨홀뚜껑은, 종래의 맨홀뚜껑의 문제점으로 지적된 맨홀뚜껑의 중량화 및 이를 해결하고자 행해진 부수적인 괘.해정장치의 추가설치로 인한 작업공정의 증가 등의 문제점을 극복할 수 있으며, 오히려 간단한 구성과 작업공정으로 인해 맨홀뚜껑의 경량화와 작업공정의 단축을 달성할 수 있다.As described above, the sealed and fixed manhole cover using the present inventor's packing ring is a work process due to the weighting of the manhole cover pointed out as a problem of the conventional manhole cover and the additional installation of the auxiliary ruler / release device. It can overcome the problems such as the increase of, rather, due to the simple configuration and work process can achieve a lighter weight of the manhole cover and a shorter work process.
