종래, 지면에 수직으로 관입되는 PHC 파일을 상하로 연결할 경우에는 도 1에 도시된 바와 같은 연결구(100)를 이용하였다. 즉, 도 1 및 도 2에 도시된 바와 같이, 연결구(100)가 상부 파일(1)의 하단과 하부 파일의 상단 사이에 개재되어 상부 플레이트(110)의 판면을 관통하여 형성되는 다수의 체결공(111)을 통해 상부 파일(1)과 볼트체결되고, 하부 플레이트(120)의 판면을 관통하여 형성되는 다수의 체결공(121)을 통해서는 하부 파일(2)과 볼트체결됨으로써 상,하부 파일(1, 2) 간을 연결하는 방식을 취하였다.Conventionally, a connector 100 as shown in FIG. 1 has been used to vertically connect a PHC file that is vertically penetrated to the ground. 1 and 2, a connector 100 is provided between a lower end of the upper file 1 and an upper end of the lower file and is provided with a plurality of fasteners (not shown) formed through a plate surface of the upper plate 110, And the upper and lower files 2 and 3 are fastened to the upper and lower files 1 and 2 through a plurality of fastening holes 121 formed through the plate surface of the lower plate 120, (1) and (2).
그러나, 이와 같은 종래의 PHC 파일 연결방식은 볼트체결에 소요되는 작업공수가 많은 관계로 많은 시간이 소요될 뿐 아니라, 파일(1, 2)의 내측에서 체결작업이 이루어져야 하므로 작업성도 떨어진다는 문제가 있었다.However, since the conventional PHC file connection method takes a lot of time because of a large number of workpieces required for fastening the bolts, there is a problem that workability is also lowered because the fastening operation must be performed inside the files 1 and 2 .

The upper connecting portion 210 and the lower connecting portion 230 are coupled to each other such that the upper connecting portion 210 and the lower connecting portion 230 are vertically coaxially stacked, That is, on the second plate portion 232 of Fig.
이때, 하부 연결구(230)의 제2 돌출 걸림부(도 5의 233)는 1차적으로 상부 연결구(210)의 원주방향으로 이웃하는 제1 돌출 걸림부(도 4의 213)의 사이에 수용된다. 이를 위해, 이웃하는 제1 돌출 걸림부(213)의 사이 간격은 제2 돌출 걸림부(233)의 원주방향의 길이보다 더 길게 형성된다.At this time, the second projecting portion 233 (FIG. 5) of the lower connector 230 is received between the first projecting portions 213 (see FIG. 4) which are adjacent to each other in the circumferential direction of the upper connector 210 . To this end, the interval between adjacent first protruding engaging portions 213 is longer than the circumferential length of the second protruding engaging portion 233.
이러한 상태에서, 상부 연결구(210)와 하부 연결구(230) 간의 상대적인 회전에 따라 제2 돌출 걸림부(233)의 수평부(233b)가 제1 돌출 걸림부(213)의 수평부(213b)와 상하로 포개어짐으로써 양 돌출 걸림부(213, 233) 간의 결합이 이루어진다(도 3의 동그라미 속 그림 참조). 이러한 결합관계를 달성하기 위해 본 실시예에서는 제1 돌출 걸림부(213)의 수직부(도 4의 213a)는 제2 돌출 걸림부(233)의 수직부(도 5의 233a)보다 반경방향으로 외측에 이격하여 배치되고, 각 수평부(213b, 233b)의 길이는 상기 수직부(213a, 233a) 사이의 거리보다 짧게 설정되며, 일측 수평부(213b)가 타측 수평부(233b)와 상하 중첩 가능할 정도로 일측 수직부(213b)가 타측 수직부(233b)보다 더 높게 설정된다. 이에 따라, 상부 연결구(210)와 하부 연결구(230) 간의 자유로운 상대 회전이 가능하다.The horizontal portion 233b of the second protruding engaging portion 233 is positioned between the horizontal portion 213b of the first protruding engaging portion 213 and the horizontal portion 233b of the second protruding engaging portion 233 in accordance with the relative rotation between the upper connector 210 and the lower connector 230. [ The upper and lower portions are superimposed to each other to engage between the protruding hook portions 213 and 233 (see a circle in FIG. 3). In order to achieve such a coupling relationship, in this embodiment, the vertical part (213a in FIG. 4) of the first projecting part 213 is arranged in a radial direction The length of each of the horizontal portions 213b and 233b is set shorter than the distance between the vertical portions 213a and 233a and the one horizontal portion 213b is overlapped with the other horizontal portion 233b The one vertical portion 213b is set to be higher than the other vertical portion 233b to the extent possible. Accordingly, free relative rotation between the upper connector 210 and the lower connector 230 is possible.
이때, 상부 연결구(210)의 내측 원통부(도 4의 215)는 도 5에 도시된 바와 같이 하부 연결구(230)의 제2 판면부(232) 내측에 대응하여 형성되는 제2 개방공(232a)에 일치하여 수용 결합됨으로써 상,하부 연결구(210, 230) 간의 반경방향으로의 변위를 차단하여 동축으로 유지시켜 준다.5, the inner cylindrical portion (215 of FIG. 4) of the upper connector 210 includes a second opening 232a (232a) formed corresponding to the inside of the second plate portion 232 of the lower connector 230, So that the radial displacement between the upper and lower connectors 210 and 230 is blocked to keep them coaxial.
한편, 도 7에 도시된 바와 같이 제1 돌출 걸림부(213)와 제2 돌출 걸림부(233) 간의 결합이 이루어지게 되면, 도 6에 도시된 바와 같은 고정핀(250)이 상부 연결구(210)측 테두리 지지벽부(214)의 각 삽입공(214a, 214b)에 삽입됨으로써 상,하부 연결구(210, 230) 간의 결합이 고정되게 한다. 즉, 삽입공(214a, 214b)으로 삽입되는 고정핀(250)으로 인해 제2 돌출 걸림부(233)는 원주방향으로의 상대적인 회전이 차단됨으로써 제1 돌출 걸림부(213)와의 결합이 계속 유지될 수 있다.7, when the first projecting portion 213 and the second projecting portion 233 are engaged with each other, the fixing pin 250 as shown in FIG. 6 is coupled to the upper connector 210 (210, 230) by being inserted into the insertion holes (214a, 214b) of the side frame supporting wall portion (214). That is, due to the fixing pin 250 inserted into the insertion holes 214a and 214b, the second protruding locking portion 233 is prevented from rotating relative to the first protruding locking portion 233 in the circumferential direction, .
이상에서 설명된 PHC 파일 무볼트 연결구(200)는 본 발명의 이해를 돕기 위한 일 실시예에 불과하므로 본 발명의 권리범위 내지 기술적 범위가 상기 설명된 바에 한정되는 것으로 이해되어서는 곤란하다. 본 발명의 권리범위 내지 기술적 범위는 후술하는 특허청구범위 및 그 균등범위에 의해 정하여진다.It is difficult to understand that the scope of the present invention and the technical scope thereof are limited to those described above since the PHC file non-volant connector 200 described above is only one embodiment for facilitating understanding of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
