도시된 바와 같이 본 고안은 나사선이 구비된 원통형의 트레드바(10)와, 상기 트레드바(10)에 체결되는 센트럴라이저(20)와 캡(30) 및 베어링플레이트(40)로 구성되는 지중 앵커(100)에 있어서,As shown, the present invention has a cylindrical tread bar 10 having a thread, and an underground anchor composed of a centralizer 20 and a cap 30 and a bearing plate 40 fastened to the tread bar 10. In 100,

상기 트레드바(10) 양측면을 절개하여 절개되지 않은 양측면에만 나사선(11)을 형성하고, 상기 트레드바(10)에 센트럴라이저(20)가 해제, 결합 될 수 있도록 삽입홈의 내측면은 나사선(21)과 비나사선(22)이 대칭으로 형성되며, 상기 센트럴라이저(20)와 캡(30) 및 베어링플레이트(40)가 설치되지 않은 트레드바(10) 몸체에 튜브(50)가 삽입되어 구성되는 것이다.The inner side of the insertion groove is a threaded line so that the threaded portion 11 is formed only on both sides of the tread bar 10 that are not cut by cutting the tread bar 10, and the centralizer 20 is released and coupled to the tread bar 10. 21 and the non-threaded line 22 is formed symmetrically, the tube 50 is inserted into the body of the tread bar 10 in which the centralizer 20, the cap 30 and the bearing plate 40 are not installed. Will be.

그리고 상기 트레드바(10)의 나사선(11)은 센트럴라이저(20)의 삽입홈 내측면에 형성된 나사선(21)과 결합되고, 트레드바(10)를 회전시켜 트레드바의나사선(11)이 센트럴라이저(20)의 삽입홈 내측면에 형성된 비나사선(22)에 위치하여 해제될 수 있도록 구성되는 것이다.The thread 11 of the tread bar 10 is coupled to the thread 21 formed on the inner surface of the insertion groove of the centralizer 20, and the thread 11 of the tread bar is rotated by rotating the tread bar 10. The non-screw line 22 formed in the inner surface of the insertion groove of the riser 20 is configured to be released.

상기 튜브(50)는 원통형관으로 지중 앵커(100)를 지중에 매설하고 콘크리트 몰탈 주입 시 콘크리트가 트레드바(10)에 묻어 경화되지 않도록 트레드바(10) 몸체 외측 둘레에 밀착되게 삽입되어 구성되는 것이다.The tube 50 is a cylindrical tube buried underground anchor 100 in the ground and is inserted into close contact with the outer circumference of the body of the tread bar 10 so that the concrete is not hardened by buried in the tread bar 10 when the concrete mortar is injected will be.

상기와 같이 구성된 본 고안의 동작 및 작용에 대하여 설명하면 다음과 같다.Referring to the operation and operation of the present invention configured as described above are as follows.

먼저, 본 고안은 지중 앵커를 제작할 때는 트레드바(10) 하부 나사선에 캡(30)이 체결되고, 상기 캡(30) 상단의 트레드바(10) 몸체 외측둘레에 튜부(50)가 밀착되어 삽입되며, 상기 튜브(50) 상단의 트레드바(10) 몸체 나사선에 센트럴라이저(20)가 결합되고, 상기 센틀럴라이저(20) 상단의 트레드바(10) 몸체 외측둘레에 튜부(50)가 밀착되어 삽입되며, 상기 튜부(50) 상단의 트레드바(10) 몸체 나사선에 센트럴라이저(20)가 결합되고, 상기 센틀럴라이저(20) 상단의 트레드바(10) 몸체 외측둘레에 튜부(50)가 밀착되어 삽입되며, 상기 튜부(50) 상단의 트레드바(10) 몸체 나사선에 베어링플레이트(40)가 체결되는 것이다.First, when the underground anchor is manufactured, the cap 30 is fastened to the lower thread of the tread bar 10, and the tub 50 is tightly inserted into the outer circumference of the body of the tread bar 10 at the top of the cap 30. The centralizer 20 is coupled to the tread bar 10 body thread on the upper end of the tube 50, and the tub 50 is in close contact with the outer circumference of the body of the tread bar 10 on the top of the centralizer 20. The centralizer 20 is coupled to the tread bar 10 body thread of the upper end of the tub 50, and the tub 50 is formed on the outer circumference of the body of the tread bar 10 of the top of the centralizer 20. Is inserted in close contact, the bearing plate 40 is fastened to the body thread of the tread bar 10 of the upper end of the tub 50.

이어서, 전송관으로 콘크리트 몰탈을 주입하면, 콘크리트 몰탈이 전송관을 통하여 홀 또는 관체의 저면으로부터 충진되기 시작하며, 충진이 완료됨과 동시 전송관을 빼낸 채 그대로 경화시키는 것이다.Subsequently, when the concrete mortar is injected into the transmission tube, the concrete mortar begins to be filled from the bottom of the hole or the tube through the transmission tube, and the filling is completed and the curing is performed while removing the simultaneous transmission tube.

이때, 트레드바(10) 몸체 외측 둘레에 밀착되게 삽입되어 있는 튜브(50)로 콘크리트 몰탈이 트레드바(10)에 간섭을 주지 않고, 콘크리트 몰탈이 경화되면 트레드바(10)를 회전시켜 트레드바의 나사선(11)이 센트럴라이저(20)의 삽입홈 내측면에 형성된 비나사선(22)에 위치하여 용이하게 해제되고, 캡(30)과 튜브(50) 및 센트럴라이저(20)만 지하에 매설되며, 상기 트레드바(10)가 해제된 홀에 콘크리트 몰탈을 주입 후 경화시킴으로서 연약한 지반을 다지게 되는 것이다.At this time, the concrete mortar does not interfere with the tread bar 10 by the tube 50 inserted in close contact with the outer circumference of the body of the tread bar 10, and when the concrete mortar is hardened, the tread bar 10 is rotated to rotate the tread bar 10. Screw thread 11 of the centralizer 20 is located on the non-threaded line 22 formed on the inner side of the insertion groove of the centralizer 20, and is easily released. Only the cap 30, the tube 50, and the centralizer 20 are buried underground. By injecting and hardening concrete mortar into the hole in which the tread bar 10 is released, the ground becomes soft.

본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

상기와 같이 구성되고 작용하는 본 고안은 지중 앵커를 제작하여 지중에 매설하고 콘크리트 몰탈 주입 후 트레드바를 용이하게 해제할 수 있어 작업공정 시간을 단축하고 트레드바가 해제된 홀에 콘크리트 몰탈을 주입 후 경화시킴으로서 연약한 지반을 다질 수 있는 유용한 고안이다.The present invention constructed and acting as described above can make underground anchors and bury them in the ground and release the tread bars easily after the injection of concrete mortar, thereby reducing the work time and injecting and hardening the concrete mortar into the holes where the tread bars are released. It is a useful design for compacting soft ground.
