상기와 같이 구성된 철근 연결장치의 작용을 설명하면 다음과 같다.Referring to the operation of the rebar connecting device configured as described above are as follows.
도 3 및 도 4와 같이, 슬리브(110)에 쐐기부재(120)를 설치하는데, 먼저 자석성질을 띤 다수의 쐐기부재(120)를 1조로 하여 먼저 양 수축관부(112)의 각 안내홈(111)을 따라 확장관부(113)까지 슬라이드시킨 다음, 또 다른 다수의 쐐기부재 (120)를 2조로 하여 먼저 삽입된 쐐기부재(120)와 맞닿게 슬라이드시킨다.3 and 4, the wedge member 120 is installed in the sleeve 110. First, a plurality of wedge members 120 having magnetic properties as a pair of first guide grooves of both of the shrinkage pipe parts 112 ( Then slide along the expanded tube portion 113 along the 111, and then slides in contact with the first inserted wedge member 120 in a pair of another wedge member (120).
이때, 다수의 쐐기부재(120)를 도 5와 같이 연결링(122)에 끼움 설치한 다음, 연결링(122)을 오므린 상태에서 쐐기부재(120)를 확장관부(113)의 안내홈(111)에 각각 위치시켜도 된다.At this time, the plurality of wedge member 120 is inserted into the connection ring 122 as shown in FIG. 5, and then the wedge member 120 is guide grooves of the expansion pipe part 113 in a state of pinching the connection ring 122. 111), respectively.
그런 다음, 슬리브(110)의 양 수축관부(112)로 각 선단부가 상호 맞닿도록 철근(200)(300)을 삽입하는데, 철근(200)(300)이 확장관부(113)를 통과할 때 안내홈(111)에 설치되어진 쐐기부재(120)와 접촉되나, 도 4의 (a)와 같이 철근(200)(300)의 단부, 또는 마디부(210)(310)가 쐐기부재(120)의 꼭지점과 접촉된 다음, 쐐기부재(120)의 변을 타고 슬라이드되며, 이때 쐐기부재(120)는 철근(200)(300)의 삽입력에 의해 안내홈(111)을 따라 밀려 들어가다가 안내홈(111)의 끝에 걸려 더 이상 들어가지 않고 철근(200)(300)만 삽입된다.Then, the reinforcing bars 200 and 300 are inserted into each of the shrinking pipe parts 112 of the sleeve 110 so that the tip ends abut each other, and guides when the rebars 200 and 300 pass through the expansion pipe part 113. In contact with the wedge member 120 is provided in the groove 111, the end of the reinforcing bars 200, 300, or nodes 210, 310 as shown in Figure 4 (a) of the wedge member 120 After being in contact with the vertex, the slide along the side of the wedge member 120, the wedge member 120 is pushed along the guide groove 111 by the insertion force of the reinforcement (200) (300) and then guide groove ( 111 is caught by the end of the reinforcing bar 200 and only 300 is inserted.
상기와 같이 슬리브(110)에 철근(200)(300)이 완전히 삽입된 상태에서 철근(200)(300)에 인장력이 가해지면 도 4의 (b)와 같이 철근(200)(300)의 두 마디부(210)(310)에 각 쐐기부재(120)의 꼭지점이 걸리면서 안내홈(111)을 따라 수축관부(112) 방향으로 내려 오다가 수축관부(112)의 내부턱에 쐐기부재(120)가 걸림과 동시에 이의 일측 꼭지점이 철근(200)(300)의 마디부(210)(310)와 강하게 가압되므로서 철근(200)(300)이 슬리브(110)의 바깥으로 이탈하는 것을 방지한다.When the tensile force is applied to the rebars 200 and 300 in a state where the rebars 200 and 300 are completely inserted into the sleeve 110 as described above, the two of the rebars 200 and 300 are as shown in FIG. While the vertices of each wedge member 120 are caught by the node portions 210 and 310, the wedge member 120 descends along the guide groove 111 in the direction of the contraction tube portion 112, and then the inner jaw of the contraction tube portion 112. Simultaneously with this, one side vertex thereof is strongly pressed with the node portions 210 and 310 of the reinforcement 200 and 300 to prevent the reinforcement 200 and 300 from escaping to the outside of the sleeve 110.
또한, 도 6과 같이 2개 또는 3개의 호형상으로 형성된 쐐기부재(120')를 두 수축관부(112)를 통해 도 7의 (a)와 같이 설치한 다음, 철근(200)(300)을 삽입하여 외측으로 당기게 되면, 쐐기부재(120')의 마디 삽입홈(121')에 철근(200)(300)의 마디부(210)(310)가 걸려 철근(200)(300)이 슬리브(110)의 바깥으로 이탈되는 것이 방지되며, 이때 상기 슬리브(110) 중간의 쐐기공(114)을 통해 두 철근(200)(300) 사이에 쐐기(130)를 박아 두 철근(200)(300)이 유동하는 것을 방지한다.In addition, the wedge member 120 'formed in two or three arc shapes as shown in FIG. 6 is installed as shown in FIG. 7A through the two contracting tube portions 112, and then the reinforcing bars 200 and 300 are installed. When inserted and pulled outward, the node portions 210 and 310 of the reinforcement 200 and 300 are caught in the node insertion groove 121 'of the wedge member 120' and the reinforcement 200 and 300 are sleeves ( It is prevented to escape to the outside of the 110, at this time through the wedge hole 114 in the middle of the sleeve 110, wedged wedge 130 between the two bars (200, 300) two bars (200, 300) Prevent it from flowing.
또한, 상기 쐐기(130) 대신에 도 7의 (b)와 같이 슬리브(110) 중간의 쐐기공 (114)을 통해 경화제(140)를 충진하여 철근(200)(300)의 유동을 방지하여도 된다.In addition, instead of the wedge 130, as shown in Figure 7 (b) to fill the hardener 140 through the wedge hole 114 in the middle of the sleeve 110 to prevent the flow of the reinforcement (200, 300) do.
따라서, 본 발명은 철근 연결장치의 구조를 극히 단순화시켜 두 철근 사이의 연결부의 기계적 강도를 향상시키면서도 철근의 연결작업을 매우 용이하게 하므로서 공기단축과 시공비용을 절감할 수 있게 한 매우 유용한 효과가 있다.Therefore, the present invention has a very useful effect of greatly simplifying the structure of the reinforcing bar connecting device while improving the mechanical strength of the connecting part between the two bars, thereby greatly reducing the air shortening and the construction cost. .
