통상의 I빔(1)의 중간을 절단하여 한쌍의 T빔(2)을 제조하고, T빔(2)에 형성된 상판(21)의 외측단을 절단하며, 상기 상판(21)의 내측단에 굴곡부(211)를 가공하여 측부재(3)를 제조하는 측부재 제조공정(101;도1참조)과;A pair of T-beams 2 are prepared by cutting the middle of a conventional I-beam 1, and cutting the outer end of the upper plate 21 formed on the T-beam 2, and on the inner end of the upper plate 21. A side member manufacturing process 101 (see FIG. 1) for manufacturing the side member 3 by processing the bent portion 211;
상기와 같이 구성된 측부재(3)의 굴곡부(211)를 서로 마주보게 위치시킨후, 수직판(22)의 내측과 상판(21)의 하측에 고무재를 충진시켜 연결부재(4)를 완성하는 연결부재 제조공정(102;도2참조)과;After positioning the bent portion 211 of the side member 3 configured as described above to face each other, and filling the inner side of the vertical plate 22 and the lower side of the upper plate 21 to complete the connecting member (4) A connection member manufacturing process 102 (see FIG. 2);
상기 측부재(3)를 이루는 수직판(22)의 외측단에 다수의 고정대(5)를 용접하고, 수직판(22)의 하측에는 별도의 보조판(6)을 용접하는 용접공정(103;도2참조)으로 신축이음을 제작함을 특징으로 하는 것이다.Welding process (103) for welding a plurality of fixing bars (5) to the outer end of the vertical plate 22 forming the side member 3, and a separate auxiliary plate 6 in the lower side of the vertical plate 22; 2) the expansion joint is characterized in that the production.
상기 방법을 좀더 구체적으로 설명하면 다음과 같다.The method is described in more detail as follows.
먼저, 통상적인 I빔(1)을 제작함에 있어서, 수직판의 상,하면과 상,하판을 서로 연결할 경우에는, 격판형상의 모재에 전원을 연결하여 압접하는 방법이 사용되었다. 따라서, 상기 압접부분은 밀착되어 접합되는 것으로서, 다른 재질의 용접재등이 사용되지 않게 됨으로서, 장기간 사용할 때 균열이 발생되지 않는 특성을 가지고 있어, I빔(1)은 건축 및 토목 현장에서 기초재로 널리 사용되는 것이다.First, in manufacturing the conventional I-beam 1, when connecting the upper, lower and upper and lower plates of the vertical plate, a method of press-contacting by connecting a power source to the base plate-shaped base material was used. Therefore, the press-contacting portion is in close contact with each other, and the welding material of another material is not used, so that the crack does not occur when used for a long time, and thus the I beam 1 is a base material in construction and civil works. It is widely used as.
따라서, 상기 측부재 제조공정(101)에서는, 먼저 I빔(1)의 중간부분을 커팅하여 대칭되는 T빔(2)을 제조한후, T빔(2)을 이루는 상판(21)의 일단을 절단하며,내측단에는 양측에 위치되는 T빔(2)의 내측이 서로 맞물릴 수 있도록 굴곡부(211)를 형성하는 것이다.Therefore, in the side member manufacturing process 101, first, the intermediate portion of the I beam 1 is cut to produce a symmetric T beam 2, and then one end of the upper plate 21 constituting the T beam 2 is removed. Cutting, the inner end is to form a bent portion 211 so that the inner side of the T beam (2) located on both sides can be engaged with each other.
또한, 상기 연결부재 제조공정(102)에서는, 측부재(3)를 이루는 상판(21)의 굴곡부(211)를 서로 마주보게 위치시킨후, 수직판(22)의 내측면과 상판(21)의 하면에 전체적으로 고무재를 도포함과 동시에, 상부 중간에는 측부재(3)의 신축시 이를 상쇄할 수 있도록 원호부(41)를 형성시키는 것이다.In addition, in the connecting member manufacturing process 102, the bent portions 211 of the upper plate 21 forming the side member 3 face each other, and then the inner surface of the vertical plate 22 and the upper plate 21 At the same time as the rubber material on the lower surface as a whole, the upper middle is to form an arc portion 41 so as to offset the expansion and contraction of the side member (3).
한편, 상기와 같이 측부재(3) 및 연결부재(4)가 일체로 제조된 후에는, 측부재(3)를 이루는 수직판(22)의 외측단에 다수의 고정대(5)를 용접하고, 수직판(22)의 하측에는 별도의 보조판(6)을 용접하여 신축이음을 완성하는 것이다.On the other hand, after the side member 3 and the connecting member 4 are manufactured integrally as described above, a plurality of fixing bars 5 are welded to the outer ends of the vertical plates 22 constituting the side member 3, The auxiliary plate 6 is welded to the lower side of the vertical plate 22 to complete the expansion joint.
상술한 바와 같은 본 발명은, 수직판과 상,하판이 연결되어 있는 통상의 I빔을 이용하여 신축이음을 제조함으로서, 신축이음을 장기간 사용할 경우에도 연결부에서 균열이 발생되는 것을 방지하여 신축이음의 수명을 연장할 수 있는 효과가 있는 것이다.The present invention as described above, by manufacturing the expansion joint using a normal I-beam is connected to the vertical plate and the upper and lower plates, even if the expansion joint is used for a long time to prevent cracking in the connection portion of the expansion joint There is an effect that can extend the life.
본 발명은 도면에 도시된 일실시예를 참고로 설명 되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에 통상의 지식을 지닌자라면 이로부터 다양한 변형 및 균등한 타실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
