본 고안은 흙막이 공사시 흙막이 벽체를 지지하기 위한 앵커 구조물에 있어서, 인장재의 해체가 가능한 제거식 앵커체에 관한 것이다. 제거식 앵커체는 일종의 가설재로서 구조물에 설치된 후, 앵커체를 구성하는 인장재(강봉, 철근 또는 강연선)가 선단앵커헤드에서 해체되어 제거되는데 , 상기 인장재를 앵커체의 선단앵커헤드로부터 용이하게 분리시키기 위하여 여러 가지 인장재 해체수단을 채택하고 있다.The present invention relates to a removable anchor body capable of dismantling a tension member in an anchor structure for supporting a retaining wall at the time of construction. The removable anchor body is a kind of temporary material installed in the structure, and then the tension member (steel bar, reinforcing bar or strand) constituting the anchor body is dismantled and removed from the tip anchor head. The tension member is easily separated from the tip anchor head of the anchor body. Various tension dismantling means are adopted for this purpose.

종래 기술에 의한 인장재의 해체 수단은 인장재를 돌려서 해체 시키거나 용수철 스프링을 이용하여 해체하는 방법을 채택하고 있는데, 인장재를 돌려서 해체하는 방식의 경우 앵커체가 지반 변형등으로 휠 경우 돌려서 해체가 어려운 상황이 종종 발생하게 되고, 용수철 스프링을 이용시는 운반시 충격등으로 인장전 해체가 발생하거나 제조 과정이 복잡하여 비경제적이었다.The conventional means for dismantling a tension member adopts a method of dismantling the tension member by turning it or using a spring. In the case of dismantling the tension member, it is difficult to dismantle it when the anchor body is bent due to ground deformation. It often occurs, when using a spring spring, it was uneconomical because the tension before disassembly occurs due to the impact during transportation or the manufacturing process is complicated.

본 고안은 상기와 같은 종래 기술의 단점을 해결 할 수 있는 앵커체를 제공함을 목적으로 한다.The object of the present invention is to provide an anchor body that can solve the disadvantages of the prior art as described above.

가설 앵커로 사용하고 인장재를 제거할 때, 어떠한 경우로 인하여 앵커체가 휘어지는 등의 변형이 일어나도 인장재의 해체가 가능하고 설치 및 운반시 충격 등이 발생하여도 선단앵커헤드내의 웨지와 인장재의 풀림이 없도록 하여 인장력 발휘 및 회수가 확실한 제거식 앵커를 제공함을 그 목적으로 한다.When used as a temporary anchor and removing the tension member, the tension member can be disassembled even if the anchor body is deformed due to some cases, and the wedge and tension member in the tip anchor head are not loosened even if an impact occurs during installation and transportation. It is an object of the present invention to provide a removable anchor that exhibits tensile strength and recovery.

도면에 따라 본 고안을 설명한다.The present invention will be described according to the drawings.

도1은 본 고안에 의한 제거식 앵커의 사시도로써, 천공 길이 방향으로 피복된 인장재(1)를 내하체(3)에 설치하고, 상기 내하체 한쪽 단부에 설치된 선단앵커헤드(4)에 의해 인장재(1)가 고정되어 제거식 앵커체를 형성한 것이다.1 is a perspective view of a removable anchor according to the present invention, in which a tension member 1 coated in the lengthwise direction of drilling is installed on a lower body 3, and a tension member is provided by a tip anchor head 4 provided at one end of the lower body. (1) is fixed to form a removable anchor body.

One wedge 7 and the fixing unit 5, the wedge cap 9 is coupled to the wedge and moved together in the longitudinal direction, the plate spring 10 is installed by a tightening bolt 12, the screw portion of the fixing unit 5 It consists of an anchoring cap 6 provided with the latching jaw 13 installed by turning to 14.

도3은 도1에 도시된 선단앵커헤드부의 분해 단면도의 또 다른 일 예의 사시도로써, 판스프링(10) 후면에 용수철 스프링(15)을 더 구비한 것을 특징으로 한다.Figure 3 is a perspective view of another example of the exploded cross-sectional view of the tip anchor head shown in Figure 1, characterized in that the spring spring 15 is further provided on the back of the leaf spring (10).

도4는 도2 및 도3에 도시된 웨지캡 및 판스프링의 상세 단면도 및 사시도로써, 웨지(7)와 결속되는 웨지캡(9) 후면에 조임볼트(12)에 의해 고정되는 탄성의 판스링(10)으로 구성되며, 여기서 판스프링은 한 방향으로 곡률이 있어 인장 반대방향으로 밀 때는 판스프링이 오무라들며 정착구캡(6)에 설치된 걸림턱(13)을 넘게되나, 인장재(1)를 잡아 당길 때는 걸림턱(13)에 걸려 웨지(7)와 웨지캡(9)은 움직이지 않고 인장재(1)만 웨지에서 빠져나오도록 한 것이다.4 is a detailed cross-sectional view and a perspective view of the wedge cap and the leaf spring shown in Figures 2 and 3, an elastic leaf spring fixed by a tightening bolt 12 to the back of the wedge cap (9) that is engaged with the wedge (7) It consists of (10), where the leaf spring has a curvature in one direction and when the plate spring is pushed in the opposite direction, the leaf spring is inclined and exceeds the locking jaw (13) installed in the anchor cap (6), but the tension member (1) When pulling out, the wedge 7 and the wedge cap 9 are caught by the locking jaw 13 so that only the tension member 1 comes out of the wedge.

도5는 도4에 도시된 판스프링의 정면도로써, 탄성의 판스프링(10)이 곡률 방 향으로 휘어질 때 오무라들기 편하도록 공간부(11)가 형성되어 있다.FIG. 5 is a front view of the leaf spring shown in FIG. 4, in which a space 11 is formed so as to be easily retracted when the elastic leaf spring 10 is bent in a curvature direction.

도6은 제거식 앵커체에 있어서, 인장재의 설치 및 해체 순서도로써, a 및 b는 인장재(1) 한쪽 끝에 웨지(7)와 웨지캡(9)을 설치하여 정착구(5)에 밀오넣고, 정착구에 형성된 나사부(14)에 정착구캡(6)을 돌려 설치하게 되면 정착구(6)캡의 걸림턱(13)과 판스프링(10)이 맞닿으면서 웨지(7)의 이동이 방지되어 인장재(1)는 고정되게 된다. c 및 d는 인장재 제거를 위하여 인장재를 절단하게 되면 반발력에 의하여 인장재가 뒤로 후퇴하면서 웨지(7)와 결속된 웨지캡(9)을 인장 반대 방향으로 밀게 된다. 이 경우 웨지캡(9)에 설치된 탄성의 판스프링(10)이 오무라들면서 정착구캡(6)의 걸림턱(13)을 넘게 된다. e는 인장재(1)가 후퇴된 상태에서 인장재를 인력에 의해 잡아당기게 되면 웨지(7)와 결속된 웨지캡(9)은 걸림턱(13)에 걸린 탄성의 판스프링(10)로 인하여 이동이 방지되므로 인장재(1)만 빠져나오도록 한 것이다.6 is a flow chart of the installation and dismantling of the tension member in the removable anchor body, wherein a and b are provided with a wedge 7 and a wedge cap 9 at one end of the tension member 1 and pushed into the anchorage 5. When the fixing unit cap 6 is rotated and installed on the threaded portion 14 formed in the fixing member 6, the locking jaw 13 of the fixing unit 6 cap and the leaf spring 10 come into contact with each other to prevent the wedge 7 from moving. ) Is fixed. When c and d cut the tension member to remove the tension member, the tension member is retracted by the repulsive force and pushes the wedge cap 9, which is connected with the wedge 7, in the opposite direction of the tension. In this case, the elastic leaf spring 10 installed in the wedge cap 9 is moved over and over the locking jaw 13 of the fixing unit cap 6. e is the wedge cap 9, which is coupled with the wedge 7 when the tension member 1 is pulled out by the attraction force in the retracted state of the tension member 1 is moved due to the elastic leaf spring (10) caught on the locking jaw (13) It is to prevent only the tension member (1) to come out.

본 고안에 의한 제거식 앵커 구조물은, 어떠한 경우로 인하여 앵커체가 휘어지는 등의 변형이 일어나도 인장재의 해체가 가능하고, 설치 및 운반시 충격 등이 발생하여도 선단앵커헤드내의 웨지와 인장재의 풀림이 없으며, 인장재의 제거가 확실하여 최고 품질의 제거식 앵커 시공이 가능한 효과가 있다.The removable anchor structure according to the present invention is capable of dismantling the tension member even when the anchor body is deformed due to any case, and there is no loosening of the wedge and the tension member in the tip anchor head even if an impact occurs during installation and transportation. As a result, the removal of the tension member is sure and the construction of the highest quality removable anchor is possible.
