본 발명은 철근과 철근을 이음하는 커플러 제조방법에 관한 것으로, 더욱 상세하게는 일련의 단계를 차례로 거치면서 판상의 철판에 암나사가 형성되고, 이 철판은 둥글게 말아져 철근과 철근을 이음하는 커플러로 제조되게 함으로써, 커플러 제조시 생산성을 증대시켜 생산원가는 절감하고 커플러에 나사 결합된 부위는 인장력이 증대되어 철근이 외부로 이탈되지 않도록 한 철근과 철근을 이음하는 커플러 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a coupler for joining reinforcing bars and reinforcing bars, and more specifically, a female thread is formed on a plate-shaped iron plate while passing through a series of steps, and the iron plate is rolled round to a coupler for connecting reinforcing bars and reinforcing bars. By manufacturing, by increasing the productivity in the manufacturing of the coupler to reduce the production cost and the portion screwed to the coupler relates to a coupler manufacturing method for joining the reinforcing bars and reinforcing bars so that the tensile force is increased so that the reinforcement does not escape to the outside.

일반적으로 사용하는 철근 이음장치는 대형 구조물의 기둥이나 벽체등의 수직방향으로 세워진 철근을 수직방향으로 연장시키기 위하여 다른 철근과 이음시키는 목적으로 사용된다.Commonly used reinforcing bars are used for the purpose of jointing with other reinforcing bars in order to extend them in the vertical direction.

철근 이음장치를 이용하여 철근을 이음하고자 할때에는 중공의 원통형 파이프 내부에 암나사를 형성하거나 또는 환봉을 가공한 후, 가공된 부위에 암나사를 형성한 커플러가 사용되고 있다.When the reinforcing bar is connected by using a reinforcing bar device, a coupler having a female thread formed in a hollow cylindrical pipe or a round bar is processed, and then a female thread is formed in the processed part.

한편 철근을 연결하기 위해서는 철근 단부 외주면에는 수나사를 형성한 후, 상기 철근 단부에 형성된 수사사를 커플러의 암나사와 나사 결합하는 방법으로 철 근을 이음하고 있다.On the other hand, in order to connect the reinforcing bar to form a male screw on the outer peripheral surface of the reinforcing bar end, the reinforcing bar is joined by a method of screwing the male thread formed on the reinforcing bar end with the female screw of the coupler.

이와 같은 종래 철근 이음방법을 통하여 철근과 철근을 이음할 수 있다는 이점은 있으나, 커플러를 이용하여 철근을 연결시키기 위해서는 파이프 내부에 암나사를 형성하거나 또는 환봉 내부를 가공한 후, 가공된 부위에 암나사를 형성하기 때문에 생산성이 크게 저하되어 생산원가가 상승되는 단점이 있었다.There is an advantage in that the reinforcing bars and reinforcing bars can be connected through the conventional reinforcing bar method, but in order to connect the reinforcing bars using a coupler to form a female thread inside the pipe or after processing the inside of the round bar, Because of the formation, the productivity is greatly reduced and the production cost is increased.

또한, 상기와 같은 방법을 통하여 커플러 내부에 형성되는 암나사는 나사산이 깨끗하게 형성되지 않고 거칠게 형성되기 때문에 인장력이 저하되어 이음부분이 취약하다는 제반 문제점이 있었다. In addition, there is a general problem that the female screw formed inside the coupler through the above-described method is not formed cleanly but is formed roughly, so that the tensile strength is lowered and the joint is weak.

본 발명의 목적은 상기와 같은 제반 문제점을 감안하여 안출한 것으로 일련의 단계를 차례로 거치면서 판상의 철판에 암나사가 형성되고, 이 철판은 둥글게 말아져 철근과 철근을 이음하는 커플러로 제조되게 함으로써, 커플러 제조시 생산성을 증대시켜 생산원가는 절감하고 커플러에 나사 결합된 부위는 인장력이 증대되어 철근이 외부로 이탈되지 않도록 한 철근과 철근을 이음하는 커플러 제조방법을 제공하는 데 있다.The object of the present invention is to devise in view of the above-mentioned problems, the female screw is formed on the plate-shaped iron plate while going through a series of steps in turn, the iron plate is rolled round to be made of a coupler for connecting the reinforcing bars and reinforcing bars, It is to provide a coupler manufacturing method for joining the reinforcing bars and reinforcing bar to prevent the reinforcing bar is not to the outside by increasing the productivity of the coupler to reduce the production cost by increasing the productivity and screwed to the coupler.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로 철근과 철근의 수나사를 수용할 수 있도록 일정한 길이를 가지고 판상으로 절단되는 철판 준비단계;The present invention is a steel plate preparation step that is cut into a plate having a certain length to accommodate the external thread of the reinforcing bars and rebar as a means for achieving the above object;

철판이 준비되면 철판 표면에 철근의 수나사와 나사 결합되는 암나사를 형성하는 암나사 형성단계;A female screw forming step of forming a female screw which is screwed to the male screw of the rebar on the iron plate surface when the iron plate is prepared;

암나사가 형성이 완료되면 철판을 둥글게 말면서 양단부를 밀착시키고, 밀착된 양단부를 용접하는 용접 단계;A welding step of welding the two ends by closely rolling both ends of the iron plate when the female thread is formed;

용접된 부분을 후가공하여 표면을 매끈하게 처리하고 철판이 커플러로 사용되게 하는 커플러 완성단계를 포함하는 것을 그 기술적 구성상의 기본 특징으로 한다.A technical feature of the technical construction is to include a coupler completion step of finishing the welded portion to smooth the surface and allowing the iron plate to be used as a coupler.

이상에서 살펴본 바와 같이 본 발명은 일련의 단계를 차례로 거치면서 판상 의 철판에 암나사가 형성되고, 이 철판은 둥글게 말아져 철근과 철근을 이음하는 커플러로 제조된다.As described above, the present invention is a female screw is formed on the plate-shaped iron plate while passing through a series of steps, the iron plate is rolled round is manufactured as a coupler for connecting the reinforcing bars and reinforcing bars.

따라서 커플러 제조시 판상의 철판에 암나사를 형성한 후, 이를 둥글게 말아 커플러로 간편하게 제조할 수 있기 때문에 생산성은 증대되고 생산원가는 절감될 수 있는 것이다.Therefore, since the female screw is formed on the plate-shaped iron plate during the manufacture of the coupler, it can be easily rolled up and manufactured as a coupler, thereby increasing productivity and reducing production cost.

또한, 철판 표면에 암나사가 직접 형성되기 때문에 나사산이 깨끗하게 형성되므로 인장력이 증대되어 철근이 외부로 이탈되지 않도록 않는 등의 효과가 있는 것이다.In addition, since female threads are directly formed on the surface of the iron plate, the threads are cleanly formed, so that the tensile force is increased so that the reinforcing bar does not escape to the outside.

이하 본 발명의 바람직한 실시예를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 철근과 철근을 이음하는 커플러 제조방법을 나타낸 구성도이다.1 is a block diagram showing a coupler manufacturing method for connecting the reinforcing bars and reinforcing bars according to the present invention.

본 발명의 커플러(200)는 철판 준비단계, 암나사 형성단계, 용접 단계, 커플러 완성단계를 거쳐 철근과 철근을 이음하는 커플러로 제조 사용된다.Coupler 200 of the present invention is manufactured and used as a coupler for connecting the reinforcing bars and rebars through the steel plate preparation step, female thread forming step, welding step, coupler completion step.

상기한 제조단계를 거치면서 커플러(200)로 제조된 본 발명은 종래와 같이 내벽에 암나사(110)가 형성되고, 이 암나사(110)에 나사 결합될 수 있도록 철근(300) 단부에 수나사(310)가 형성되며, 철근(300)이 커플러(200)에 나사 결합되면서 이음되는 기본적인 맥락은 종래와 같다.The present invention manufactured by the coupler 200 while the above-described manufacturing step is a female screw 110 is formed on the inner wall as in the prior art, the male screw 310 to the end of the reinforcement 300 to be screwed to the female screw 110 ) Is formed, and the basic context in which the reinforcement 300 is screwed to the coupler 200 is the same as in the related art.

상기와 같은 커플러(200)는 판상의 철판(100)에 암나사(110)가 형성되면, 이 철판(100)은 둥글게 말아져 양단부가 용접되고, 용접된 부분이 후가공되면서 커플러(200)로 형성된다.When the coupler 200 is a female screw 110 is formed on the plate-shaped iron plate 100, the iron plate 100 is rolled round to weld both ends, the welded portion is formed as a coupler 200 after the post-processing. .

이를 더욱 상세하게 설명하면 다음과 같다.This will be described in more detail as follows.

철판 준비단계, Steel plate preparation step,

철판(100)을 준비한 후, 준비된 철판(100)을 둥글게 말았을 때 철근(300)과 철근의 수나사(310) 부분을 수용할 수 있도록 일정한 길이로 절단한다. After preparing the iron plate 100, when the rolled round the prepared iron plate 100 is cut to a certain length to accommodate the reinforcement 300 and the male screw 310 portion of the reinforcement.

암나사 형성단계,Female thread forming step,

철판(100)이 준비되면 철판(100) 표면에 철근(300)의 수나사(310)와 나사 결합되는 암나사(110)를 형성한다. 이때 철판(100) 표면에 바로 암나사(110)가 형성되기 때문에 나사산 형성이 깨끗하게 이루어지고 나사 가공작업도 그만큼 간편하게 이루어지는 것이다.When the iron plate 100 is prepared, the female thread 110 is screwed to the male screw 310 of the reinforcement 300 on the surface of the iron plate 100. At this time, since the female thread 110 is formed directly on the surface of the iron plate 100, the thread is formed cleanly, and the screw machining operation is made as simple as that.

용접 단계,Welding step,

암나사(110)가 형성이 완료되면 철판(100)을 둥글게 말면서 양단부를 밀착시키고, 밀착된 양단부를 용접한다.When the female thread 110 is formed, the iron plate 100 is rolled roundly and closely attached to both ends, and the both ends are welded.

커플러 완성단계,Coupler completion stage,

용접된 부분을 후가공하여 표면을 매끈하게 처리하여 철판(100)이 커플러(200)로 사용되게 한다. 이후 철근 이음작업시에는 철근(300)의 단부에 형성된 수나사(310)를 커플러(200)의 암나사(110)에 나사 결합하면 철근의 이음작업이 완료되는 것이다.The welded portion is post-processed to smooth the surface so that the iron plate 100 is used as the coupler 200. After the reinforcing bars when the male screw 310 formed on the end of the reinforcing bar 300 is screwed to the female screw 110 of the coupler 200, the joint of the reinforcing bar is completed.

한편, 상기와 같은 커플러의 외주면 형상은 원통형으로 형성되는 것이 가장 바람직하나, 철판(100)을 이용하여 암나사(110)를 형성하고 이를 말아서 커플러(200)로 사용할 수 있다면 육각, 팔각 등과 같이 다각형으로 형성하여 사용할 수 있음을 밝혀둔다.On the other hand, the outer circumferential surface shape of the coupler as described above is most preferably formed in a cylindrical shape, if the female screw 110 is formed using the iron plate 100 and rolled it can be used as the coupler 200 in a polygon such as hexagon, octagon, etc. Note that it can be formed and used.
