제3도는 본 발명의 접합부위인 제1도의 "A"부분을 확대 분해한 일부사시도.3 is an enlarged exploded perspective view of part "A" of FIG. 1 which is a junction of the present invention.

제4도는 본 발명의 접합부위의 접합상태를 나타낸 확대단면도.Figure 4 is an enlarged cross-sectional view showing a bonding state of the joint portion of the present invention.

본 발명은 별도의 상측부재와 하측부재가 사출성형되어 상호접합되는 합성수지재 집수죠인트 및 그의 제조방법에 관한 것으로, 특히 상기 상측부재와, 상기 하측부재의 접합부분에 플렌지부와 웨브부가 일체로 형성되어 있는 금속편에 의하여 상측부재의 하단변과 하측부재의 상단변에 플렌지와 웨브 일부분이 나누워져 매입되게 용융접합되도록 함으로써 그 접합부위가 보다 견고하게 접합될 수 있도록한 합성수지재 집수죠인트 및 그의 제조방법에 관한 것이다.The present invention relates to a synthetic resin collecting joint and a method of manufacturing the resin and the manufacturing method of the upper member and the lower member is joined to each other by injection molding, in particular, the flange portion and the web portion integrally formed at the junction of the upper member and the lower member A synthetic resin collecting joint and a method of manufacturing the same, which allows the joint portion to be more firmly bonded by melting and joining the flange and the web portion between the lower side of the upper member and the upper side of the lower member by embedding the metal pieces. It is about.

종래에는 주물제로된 집수죠인트가 있었는데 이는 산화부식되기 쉬울뿐아니라 중량이 매우 많이 나가고 제품의 단가도 높아지는 결함이 있었기 때문에 중량이 가볍고 내식성이 우수한 재질로된 합성수지재 집수죠인트가 출현되었으나 집수죠인트는 형상 단면이 복잡한 관계로 인하여 사출성형기술상 하나의 몸체로서는 제작이 불가능하여서 집수죠인트를 상측부재와 하측부재로 분할하여 사출성형한후 상하측부재를 단순히 접착제로서의 상호 접합시키는 방법만으로 시도하고 있었으므로 운반및 최급시 외부충격에 의해 그 접합부위가 쉽게 이격되거나 파손되는등의 결점이 있었다.Conventionally, there was a water-collecting joint made of casting, which is not only easy to oxidize and corrode, but also has a high weight and a high unit cost of the product. Due to the complicated relationship in cross section, it is impossible to manufacture one body in the injection molding technology. Therefore, the water collecting joint was divided into the upper and lower members, and injection molding was performed. At the time of emergency, the joints were easily separated or damaged by external shock.

또한, 일본국 공개 특허공보 소59-60195호에서 보여지는 바와같이 상, 하측부재의 접합을 고주파에 의한 열융착을 시도하고는 있었으나 단순히 고주파의 열을 전달할 수 있는 "ㅁ"형상으로된 금속편을 상하부재의 사이에다 놓고서 고주파로서 가열온도를 주고 있으므로 이러한 경우의 금속편의 역활이란 단순한 열전달의 의미만을 갖는 것이어서 운반 취급시에 외부로부터 충격을 받으면 접합부위가 쉽게 이격되거나 파손되어 집수죠인트로서의 기능을 하지 못하는 것은 전자의 경우와 마찬가지인 결점을 지니게 되는 것이다.In addition, as shown in Japanese Laid-Open Patent Publication No. 59-60195, although attempting to heat-bond by the high frequency to the joining of the upper and lower members, the metal piece having a "ㅁ" shape that can simply transmit high-frequency heat Since the heating temperature is applied at high frequency while being placed between the upper and lower members, the role of the metal piece in this case is only for heat transfer. When the product is impacted from the outside during transport handling, the joints are easily spaced apart or broken to function as a collecting joint. What it does not have is the same defect as the former case.

본 발명에서도 상기와 같은 고주파 발진에 의한 금속편을 사용하여 열융착 방법을 이용하는 기술은 같다 할지라도 특히 본 발명에서는 금속편 자체에 특성을 부여하여 금속편의 기능으로서 열전달은 물론이고 전달된 융점이상의 금속편이 상하부재속으로 일부분씩 엇물리도록 파고 들어가서 상하부재가 접합되도록 하면서 금속편 자체가 상하부재에 앵커 역활을 수행하도록 한것이 본 발명이 추구하고져 하는 것이다.In the present invention, although the same technique of using the thermal fusion method using the metal pieces by the high frequency oscillation as described above is particularly the present invention, the metal pieces above the melting point transmitted as well as the heat transfer as a function of the metal pieces by giving characteristics to the metal pieces themselves are upper and lower parts. It is intended that the present invention seeks to allow the metal piece itself to perform the anchor role on the upper and lower members while digging into portions intermittently to interlock and joining the upper and lower members.

여기서 앵커역활에 대하여 설명해보면 우선 금속편은 상, 하부재와 같은 재질의 접차링이 삽입되어질수있는 공간부를 가지면서 적어도 한쪽면이 개방되어진 상태의 형상으로 되어 있고 이와같은 형상의 금속편의 공간부에다 접착링이 삽입되어진 금속편은 상, 하부재의 사이에 놓이게 되면 고주파 발진에 의해서 금속편에 전달되어진 열은 접찰링은 물론이고, 상하부재의 접합부위를 용융시키게 되는데 이때, 상, 하부재를 가압하여 밀착시키면 상, 하부재와 접면된 급속편은 상, 하부재속으로 일부분씩 파고 들어가면서 용융상태의 접착링은 한쪽으로 개방된 방향으로 흘러나와 상, 하부재의 접합면 부위와 금속편의 공간부를 골고루 충진시키게 되면 바로 이러한 상태로 경화하게 되면 금속편 자체가 상부재에 반쯤 매몰되어 있고 하부재에도 반쯤 매몰되어 있는데다가 금속편 공간부내의 접착링은 금속편 공간부를 중심으로 상, 하부를 각각 일체화시키고 있으므로 금속편은 상하부재를 견고하게 유지시키는 앵커역할을 수행하게 되는 것이다.Here, the anchor role will be described. First, the metal piece has a space in which a contact ring of the same material as the upper and lower members can be inserted, and at least one side is in an open state. When the metal piece into which the adhesive ring is inserted is placed between the upper and lower members, the heat transferred to the metal piece by the high frequency oscillation melts the joining part of the upper and lower members as well as the gluing ring. When in close contact with the upper and lower members, the quick pieces dig into the upper and lower parts one by one, and the molten adhesive ring flows in the open direction to one side and evenly fills the joint surface of the upper and lower members and the space of the metal pieces. When it hardens in this state, the metal piece itself is half buried in the upper material and half in the lower part. The molar itneundeda bonded ring of the metal pieces and the space portion is so integrated with the upper and lower parts of a metal piece in the center space, each metal piece is that it would take the anchor serve to firmly hold the top and bottom members.

또한 금속편의 형상은 앵커 역할을 충분히 수행하면서도 열전달역활을 동시에 수행할 수 있는 형상이면 족하기 때문에 예를들면 "ㄷ", "Z"등이 예시될 수 있는 것이다.In addition, since the shape of the metal piece is sufficient to perform a role of anchor while simultaneously performing a heat transfer role, for example, "c", "Z", etc. may be exemplified.
