The protrusions 5 and 8 of the coupler are installed to face each other, and the protrusions 5 of the coupler 2 are large enough to be inserted into the grooves 9 of the second coupler 7. Couple 2 and the second coupler (7) may be a binary shape judging tapered in that the assembled longitudinal direction.

상기한 특징 외의 다른 특징 및 구성에 대하여 이하, 첨부 도면에 의거 추가로 상술한다Other features and configurations other than those described above will be further described below based on the accompanying drawings.

도 1 은 본 고안에 따른 소일 네일에 대한 구성을 설명하기 위한 도면이다.1 is a view for explaining the configuration of the soil nail according to the present invention.

도시한 바와 같이, 철근(1)의 외주엔 커플러(2)가 설치된다. 커플러(2)는 철근(1)을 중심으로 좌우로 2 조각으로 분할 된 구조이다. 커플러(2)는 그 내측에 리턴스프링(11)을 상하로 2 개 이상 설치한다. 그리고 내면은 철근(1)의 돌출부(3)의형상에 부합하게 요철로 만든다. 즉, 돌출부(3)와 매치되게 오목한 홈(4)을 준다. 커플러(2)의 외주는 돌출부(5)와 홈(6)을 준다As shown in the figure, a coupler 2 is provided on the outer circumference of the reinforcing bar 1. Coupler (2) is a structure divided into two pieces from side to side around the reinforcing bar (1). The coupler 2 is provided with two or more return springs 11 on the inside thereof. And the inner surface is made of unevenness to match the shape of the protrusion 3 of the reinforcing bar (1). That is, the recessed groove 4 is provided to match the protrusion 3. The outer circumference of the coupler 2 gives the protrusion 5 and the groove 6.

그 외주로는 제2커플러(7)를 설치한다. 제 2 커플러(7) 내측에도 돌출부(8)와 홈(9)을 준다. 제2커플러(7)의 홈(9)에는 커플러(2)의 돌출부(5)가 삽입될 수 있는 정도의 크기로 만든다. 커플러(2)의 상측에는 항상 아래로 내미는 힘을 작용하고 있는 압축스프링(10)이 설치된다. 제2 커플러(7)의 상하로는 파이프(13)가 연결 설치된다The other coupler is provided with a second coupler (7). The protrusion 8 and the groove 9 are also provided inside the second coupler 7. The groove 9 of the second coupler 7 is sized such that the protrusion 5 of the coupler 2 can be inserted. The upper side of the coupler (2) is provided with a compression spring (10) that always exerts a downward force. Pipe 13 is connected to the top and bottom of the second coupler (7)

도 1 과 같은 구성으로 조립된 즉, 철근(1), 커플러(2), 제2커플러(7) 그리고 파이프(13)가 일체로 조립된 형태의 것이 천공된 천공구(15)에 삽입된다. 상기한 커플러(2) 및 제 2 커플러(7) 조립체는 도 2 에서 보듯이, 철근(1)의 긴 길이에 걸쳐 여러곳에 형성된다. 그리고 이 천공구(15)에 콘크리트(20)를 주입하여 그라우팅처리한다. 그러면 파이프(13) 및 제2커플러(7)의 외주가 콘크리트(20)와 결합되어 콘크리트(20)가 굳으면 고정된다Assembled in the configuration as shown in Figure 1, that is, the rebar (1), the coupler (2), the second coupler (7) and the pipe 13 in the form of integrally assembled is inserted into the drilled drilling tool (15). The assembly of the coupler 2 and the second coupler 7 is formed in several places over the long length of the reinforcing bar 1, as shown in FIG. Then, the concrete 20 is injected into the drilling tool 15 and grouted. Then, the outer circumferences of the pipe 13 and the second coupler 7 are combined with the concrete 20 and fixed when the concrete 20 is hardened.

상기한 구성 중 커플러(2)와 제2 커플러(7)는 다른 변형된 구성으로도 만들 수 있다. 예를들어, 커플러(2)의 외경과 제2커플러(7)의 내경을 테이퍼 형태로 만들 수 있다. 다시말해 도면상 상부쪽의 외경을 크게 이루어지고 하부쪽 외경은 작게 이루어지는 테이퍼진 형태로 만들면 조립시 편리한 장점이 있다.The coupler 2 and the second coupler 7 in the above-described configuration may be made in other modified configurations. For example, the outer diameter of the coupler 2 and the inner diameter of the second coupler 7 can be tapered. In other words, the outer diameter of the upper side is made large in the drawing and the outer diameter of the lower side is made in a tapered form made of a convenient advantage when assembling.

상기한 구성에 의한 작동을 설명한다The operation by the above configuration will be described.

소일 네일의 가설 후, 철근(1)을 뽑아 제거하고자 할 경우, 철근(1)을 아래로 내려민다. 그러면 철근(1)과 결합되어 있는 커플러(2)가 아래로 내려가, 커플러(2)의 외주에 형성된 돌출부(5)가 고정된 제2커플러(7)의 홈(9)에 도 3 과 같이 삽입된다. 왜냐하면 커플러(2)의 내주에 설치된 리턴스프링(11)이 벌어지므로 그 벌어지는 힘에 의해 커플러(2)가 좌우로 벌어져 제2커플러(7)의 홈(9)에 삽입된다.After hypothesis of the Soil Nail, if the rebar (1) is to be pulled out and removed, the rebar (1) is pushed down. Then, the coupler 2 coupled with the reinforcing bar 1 descends, and is inserted into the groove 9 of the second coupler 7 to which the protrusion 5 formed on the outer circumference of the coupler 2 is fixed, as shown in FIG. 3. do. Because the return spring 11 is installed on the inner circumference of the coupler 2 is opened, the coupler 2 is opened to the left and right by the opening force is inserted into the groove 9 of the second coupler (7).

상기와 같은 동작에 의해 철근(1)은 커플러(7)로 부터 물려있던 상태에서 해제가 되므로 손쉽게 뽑아 낼 수 있다.By the above operation, the reinforcing bar 1 can be easily pulled out because it is released from the coupler 7.

상기와 같은 본 고안에 의하면, 철근 제거 작업 중 철근이 부러지거나 하는 등의 손상 없이 그리고 신속하게 그리고 매우 편리하게 철근을 제거할 수 있다.According to the present invention as described above, it is possible to remove the reinforcing bar quickly and very conveniently without damaging the reinforcing bar during the rebar removal operation.
