본 발명은 상·하수도관 또는 오폐수관 등으로 사용되는 주철관을 연결하기 위한 압륜 어셈블리의 구성요소인 스파이크에 관한 것으로서, 보다 상세하게는 다수개의 조각편들이 각각 연결부에 의해 연결되어 환 형상으로 형성되고, 연결부에 의해 연결된 조각편들 사이에 슬릿(slit)이 형성되어, 각각의 조각편에 형성된 에지 클로우가 변형된 관체의 외주면을 모두 그립핑(gripping)할 수 있는 압륜 어셈블리용 스파이크에 관한 것이다.The present invention relates to a spike that is a component of a rolling assembly for connecting a cast iron pipe used as a water and sewage pipe or waste water pipe, and more particularly, a plurality of pieces are each connected by a connection portion is formed in an annular shape, A slit is formed between piece pieces connected by a connection part, and the edge claw formed in each piece piece relates to a spike for a pressure wheel assembly capable of gripping all the outer circumferential surface of the deformed tubular body.

대한민국 특허 제0812629호(2008년 3월 5일, 등록)에 "관 연결용 압륜 어셈블리"가 소개되어 있다.Korean Patent No. 0812629 (registered on March 5, 2008) introduces a "rolling assembly for pipe connection".

상기 관 연결용 압륜 어셈블리는 압륜의 관체 중앙에 관통공이 형성되고, 관통공의 내부는 파지링(이하, "스파이크"라고 함)을 수용할 수 있는 수용공간이 형성되며, 관체 내주면 하단에 걸림부가 있는 경사면이 형성되고, 관체 외주에 조인 트볼트가 관통하는 볼트구멍이 형성된 플랜지가 형성되어 있으며, 스파이크가 압륜의 수용공간에 수용될 수 있게 절개부가 형성되고, 스파이크의 외주면에 압륜의 경사면과 결합될 수 있게 경사면과 걸림부가 형성되며, 소켓관의 플랜지부 내공간에 밀폐링이 안치되어 있는 것을 특징으로 한다.The pipe connection pressure ring assembly has a through hole formed in the center of the tube body of the pressure ring, the inside of the through hole is formed a receiving space for accommodating the gripping ring (hereinafter referred to as "spike"), the engaging portion at the lower end of the inner tube surface The inclined surface is formed, the flange is formed with a bolt hole through which the bolt bolt through the outer periphery of the tube is formed, the incision is formed so that the spike can be accommodated in the receiving space of the pressure ring, and the inclined surface of the pressure ring on the outer peripheral surface of the spike The inclined surface and the engaging portion is formed to be possible, characterized in that the sealing ring is placed in the inner space of the flange portion of the socket tube.

그러나, 상기 관 연결용 압륜 어셈블리에 소개된 스파이크(10)는, 도 1에 도시된 바와 같이, 절개부(11)를 가진 환형상으로 형성되어 있어, 도 2에 도시된 바와같이, 제조 과정에서 또는 외력에 의해 관체(20)가 타원형으로 변형되었을 때, 관체의 장축에 해당되는 외주면에만 스파이크(10)의 에지 클로우(12 ; edge claw)가 압착되고, 관체(20)의 단축에 해당되는 외주면에는 상기 에지 클로우(12)가 압착되지 못하여, 상기 스파이크의 에지 클로우가 변형된 관체의 외주면을 전체적으로 균일하게 그립할 수 없는 단점이 있었다. However, as shown in FIG. 1, the spike 10 introduced to the tube connecting pressure assembly is formed in an annular shape with an incision 11, and as shown in FIG. 2, in the manufacturing process. Alternatively, when the tubular body 20 is deformed into an elliptical shape by an external force, the edge claws 12 of the spikes 10 are compressed only on the outer circumferential surface corresponding to the long axis of the tubular body, and the outer circumferential surface corresponding to the short axis of the tubular body 20. There was a disadvantage that the edge claw 12 could not be compressed, so that the edge claw of the spike could not grip the outer circumferential surface of the deformed tube as a whole.

따라서, 본 발명의 목적은 다수개의 조각편들이 각각 연결부에 의해 연결되어 환 형상으로 형성되고, 연결부에 의해 연결된 조각편들 사이에 슬릿(slit)이 형성되어, 조인트 볼트를 조이면, 압륜의 내부 경사면에 의해 수축되는 과정에서 연결부가 파단되어 각각의 조각편이 독립적으로 변형된 관체의 외주면을 그립핑(gripping)하거나, 슬릿이 벌어져 각각의 조각편이 변형된 관체의 외주면을 모두 그립핑(gripping)할 수 있는 압륜 어셈블리용 스파이크를 제공하는 것이다.Therefore, an object of the present invention is a plurality of pieces are each connected by the connecting portion is formed in an annular shape, a slit is formed between the pieces connected by the connecting portion, when tightening the joint bolt, by the inner inclined surface of the pressure wheel In the process of contraction, the joint is broken so that each piece can grip the outer circumferential surface of the deformed tube independently, or the slit can be opened to grip all the outer circumferential surfaces of the deformed tube. To provide a spike for the assembly.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 압륜 어셈블리용 스파이크는 절개부를 가진 환형상으로 형성되고, 내주면에 복수개의 에지 클로우(edge claw)가 형성되고, 외주면이 경사지게 형성된 압륜 어셈블리용 스파이크에 있어서,In the spike assembly for a wheel assembly according to the present invention for achieving the above object is formed in an annular shape having an incision, a plurality of edge claws are formed on the inner circumferential surface, the outer circumferential surface is inclined ,

다수개의 조각편들이 연결부에 의해 각각 연결되고, 연결부에 의해 연결된 조각편들 사이에 슬릿이 형성되는 것을 특징으로 한다.A plurality of pieces are each connected by a connecting portion, characterized in that the slit is formed between the pieces connected by the connecting portion.

본 발명에 따른 압륜 어셈블리용 스파이크는 상기 연결부가 파단되어 각각의 조각편이 변형된 조인트관의 외주면을 그립핑하게 되는 것을 특징으로 한다.Spikes for the pressure-wheel assembly according to the invention is characterized in that the connection is broken so that each piece of the gripping the outer peripheral surface of the deformed joint pipe.

다른 변형 형태로, 본 발명에 따른 압륜 어셈블리용 스파이크는 각각의 조각편 사이에 형성된 슬릿이 벌어지면서, 각각의 조각편이 변형된 조인트관의 외주면을 그립핑하게 되는 것을 특징으로 한다. In another variant, the spikes for the rolling assembly according to the present invention are characterized in that the slit formed between each piece piece is opened, and each piece piece grips the outer peripheral surface of the deformed joint tube.

이것에 의해, 본 발명에 따른 압륜 어셈블리용 스파이크는 압륜의 내부 경사면에 의해 수축되는 과정에서 연결부가 파단되어 각각의 조각편이 독립적으로 변형된 관체의 외주면을 그립핑(gripping)하거나, 슬릿이 벌어져 각각의 조각편이 변형된 관체의 외주면을 모두 그립핑(gripping)할 수 있어, 변형된 관체를 견고하게 그립핑함으로써, 변형된 관체가 압륜 어셈블리에서 이탈되는 것을 방지할 수 있는 효과가 있다.As a result, the spike for the wheel assembly according to the present invention has a connection part broken in the process of being contracted by the inner inclined surface of the wheel, so that each piece is independently gripped or gripping the outer peripheral surface of the tubular body. The pieces of can grip all of the outer circumferential surface of the deformed tube, so that the deformed tube is firmly gripped, thereby preventing the deformed tube from being detached from the pressing assembly.
