Description

안전 연결형 상하수도관{A pipe}Safety connection water and sewage pipe {A pipe}

본 발명은 안전 연결형 상하수도관에 관한 것으로, 더욱 상세하게는 플랜지를 체결하면서 플랜지의 원주방향을 따라서 같은 간격에 설치한 연결 홈부에 연결부재를 설치하여 양쪽의 플랜지를 잡아주고, 상기 연결부재에 체결볼트와 너트의 체결력으로 체결함으로써 플랜지가 강한 체결력으로 고정되면서 상하수도관을 견고하게 고정하여 수밀이 유지되도록 안정되게 연결하는 안전 연결형 상하수도관에 관한 것이다.
The present invention relates to a safety connection type water supply and sewage pipe, and more particularly, by connecting the connection member to the connecting grooves provided at equal intervals along the circumferential direction of the flange while holding the flanges, and fastening to the connection member. The fastening force of the bolt and nut relates to a safety connection type water and sewage pipe that securely connects the water supply and drainage pipe while the flange is secured by the strong fastening force so as to maintain watertightness.

일반적으로 액체 또는 기체류의 물질을 이송하기 위해서는 상하수도관(수도관, 이중벽 하수관, 삼중벽 하수관 등)을 이용하게 되며, 이용하고자 하는 물질의 특성 및 사용용도에 따라 여러 가지 형태의 모양과 재질로 이루어지게 되고, 금속관, 합성수지관, 유리섬유 복합관 등으로 구분되고 별도의 연결수단에 의해 연결되어 사용되고 있다.In general, water and sewage pipes (water pipes, double wall sewer pipes, triple wall sewer pipes, etc.) are used to transfer liquid or gaseous materials, and are made of various shapes and materials depending on the characteristics of the materials to be used and the intended use. It is divided into metal pipes, synthetic resin pipes, glass fiber composite pipes, etc., and is connected and used by separate connection means.

이를 위해 종래의 관 연결구조는 등록특허번호 제0770167호(2007. 10. 19. 등록)에 게재된 바와 같이, 관이 열융착되는 아답터와 연결되는 플랜지의 외측으로 돌출부와 홈부를 형성하고, 돌출부에서는 볼트와 너트를 서로 체결하는 연결구조를 제공하며 플랜지의 밀착면에 형성된 결합공면을 안쪽으로 경사지게 구성하여, 이 후 결합수단을 통해 결합공을 압박하면 결속력으로 경사진 결합공면이 상호 밀착되어 보다 안정적으로 플랜지를 고정할 수 있도록 하는 것이다.To this end, the conventional pipe connection structure is formed in the Patent No. 0770167 (2007. 10. 19. registration), the protrusions and grooves formed on the outside of the flange that is connected to the adapter that the tube is heat-sealed, the protrusions Provides a connection structure for fastening the bolt and nut to each other, and the coupling hole formed on the contact surface of the flange is inclined inward, and when the coupling hole is pressed through the coupling means, the coupling hole inclined by the binding force is in close contact with each other. It is to allow the flange to be fixed stably.

그러나 이러한 종래의 관 연결구조는 일정한 간격으로 다수개의 볼트를 결합하여 체결력을 전달하게 되므로, 볼트가 설치된 주변에서는 정상적으로 조임력이 전달되지만, 볼트의 사이에 있는 공간에서는 조임력이 정상적으로 전달되지 못하게 되므로 볼트가 설치되지 않은 사이의 공간에서는 조임력이 약해지는 결점이 발생하게 되므로 전체적으로 균일한 조임력을 제공할 수 없는 단점이 발생하게 된다.However, in the conventional pipe connection structure, a plurality of bolts are coupled at regular intervals to transmit a clamping force, and thus a tightening force is normally transmitted in the vicinity of the bolt, but a bolt is not normally transmitted in a space between the bolts. In the space between the installation does not have the disadvantage that the tightening force is weakened, the overall disadvantage that can not provide a uniform tightening force occurs.

그리고 조임력이 발생하지 않는 부분은 홈부로 형성되므로 취약한 결점이 발생하며, 플랜지의 사이에 삽입되거나 상하수도관의 사이에 설치되는 고무링은 링 형태를 제공하게 되므로 링 형태의 면에서 강한 밀착력을 제공하는 것이 한계가 있어서 수밀을 유지하는 것이 불안정한 결점이 발생하게 된다.In addition, since the portion in which the tightening force does not occur is formed as a groove, a weak defect occurs, and the rubber ring inserted between the flanges or installed between the water and sewage pipes provides a ring shape, thereby providing a strong adhesion in terms of the ring shape. There is a limit to this, which results in an unstable defect in maintaining watertightness.

또한, 볼트를 이용하여 너트를 회전시켜 조임력을 전달함에 있어서, 인력을 이용하여 조임력을 가하게 되므로 작업자에 따라서 조임력이 각기 다르게 제공되므로 균일한 조임력을 제공하는 것이 어렵고, 플랜지가 정상적으로 원주방향에서 균일하게 체결되었는지를 확인하는 것이 불가능하여 체결 여부를 정확하게 알 수 없는 결점이 있었다.In addition, in the transmission of the tightening force by rotating the nut using a bolt, the tightening force is applied by the manpower, so it is difficult to provide a uniform tightening force because the tightening force is provided differently according to the operator, the flange is normally uniform in the circumferential direction There was a flaw in which it was impossible to know exactly whether or not it was concluded.

또한, 볼트 머리부분과 너트를 통하여 조임력이 가해질 때 합성수지로 이루어진 부분에서 강도에 취약하므로 조임력으로 파손되는 결점이 발생하게 된다.In addition, when the tightening force is applied through the bolt head and the nut, the part made of synthetic resin is vulnerable to strength, so that a defect occurs due to the tightening force.

한편, 볼트와 너트를 결합하여 연결하는 플랜지를 상하수도관의 외경에 결합하여 용접 연결하여 일체형으로 조립하게 되므로 생산된 상하수도관과 플랜지를 용접 연결하기 위한 용접 연결작업을 별도로 수행해야 하는 것이어서 생산과정이 복잡해지는 결점이 발생하며, 상하수도관의 외경보다 더 큰 외경을 갖는 플랜지가 돌출된 상태에서 보관 및 이동과 설치작업을 수행해야 하는 것이어서 이러한 과정에서 얇게 노출된 플랜지가 충격으로 쉽게 변형되거나 손상되어 사용이 어려운 결점과 함께, 상하수도관의 생산 길이(약 6미터) 양쪽에 플랜지를 연결하여 작업을 수행하지만, 상하수도관의 일부분을 절단하여 연결작업을 수행해야 하는 경우에는 플랜지가 없어서 연결작업을 수행하는 것이 매우 어려운 단점이 있었다.
On the other hand, since the flange connecting the bolt and nut by connecting to the outer diameter of the water and sewage pipe is welded and assembled in one piece, the welding process for welding and connecting the produced water and sewage pipe and the flange must be performed separately. Complicated defects occur, and storage, movement, and installation work must be carried out while the flange having an outer diameter larger than that of the water supply and sewage pipe is protruded. With this difficult drawback, the work is done by connecting flanges to both sides of the production line (approximately 6 meters) of the water and sewage pipes. It was very difficult disadvantage.
