즉 도7에서와 같이 앵커(100)가 암반(10)의 구멍(20)에 끼워진 상태에서 각형 봉체(220)를 이용하여 축봉(200)을 회전시키면 나사봉체(210)에 나사결합된 승강체(300)는 각형봉체(220)쪽으로 이동하게 된다.That is, as shown in FIG. 7, when the shaft 100 is rotated using the rectangular rod body 220 in the state where the anchor 100 is fitted into the hole 20 of the rock 10, the screw rod is lifted and screwed to the threaded rod body 210. The sieve 300 is moved toward the rectangular rod body 220.

상기에서와 같이 승강체(300)가 각형봉체(220)쪽으로 이동하게 되면 승강체(300)에 구성된 확개편(340)의 경사면(341)이 고정판(400)의 조립공(420)에 끼워진 확장걸림판(500)의 경사면(521)과 접하고 있기 때문에 확장걸림판(500)은 연결편(530)을 축으로 벌어지면서 본체(550) 외측면에 구성된 톱니형 걸림편(510)이 구멍(20)의 내측면을 파고들면서 고정이 되므로 축봉(200)을 외측방향으로 잡아당기더라도 빠지지 않고 견고히 고정된다.As described above, when the lifting member 300 moves toward the rectangular rod body 220, the inclined surface 341 of the extension piece 340 configured in the lifting member 300 is fitted into the assembly hole 420 of the fixing plate 400. Since the engaging plate 500 is in contact with the inclined surface 521 of the plate 500, the expansion engaging plate 500 has a toothed engaging piece 510 formed on the outer surface of the main body 550 while the connecting piece 530 is axially opened. Since it is fixed while digging the inner surface, it is firmly fixed without pulling out the shaft bar 200 in the outward direction.

이때 확장걸림판(500)은 고정판(400)상에 서로 분리된 상태에 개별적으로 확장이 되므로 보다 견고한 지지가 이루어질 수 있게 될뿐 아니라 확장걸림판(500)은 강철소재를 프레스단조작업으로 하여 제조케 하므로서 견고성을 배가시킬 수 있게 된다.At this time, the expansion catching plate 500 is expanded on the fixed plate 400 separately from each other, so that not only can be more firmly supported, but also the expansion catching plate 500 is manufactured by press forging of steel materials. By doing so, the robustness can be doubled.

암반구멍(20) 외측으로 돌출된 축봉(200)의 나사부(221)에는 고정하고자 하는 구조물(30)을 끼운 다음 너트(223)로 체결고정되게 하므로서 구조물(30)이 암반(10)상에 견고히 고정된다.The structure 30 is firmly mounted on the rock 10 by inserting the structure 30 to be fixed in the threaded portion 221 of the shaft rod 200 protruding out of the rock hole 20 and then fastening and fastening with the nut 223. It is fixed.
