본 발명은 인장재 제거형 그라운드 앵커에서 토류벽 등의 구조물을 관통한 인장재의 외측단이 정착되는 외부 정착체를 받쳐주는 받침에 관한 것이며, 특히 외부정착을 해제하기 위한 인장재의 외측단 절단이 용이하고, 토류벽 등의 토목구조물 외측에 절단된 인장재의 외측단이 여유 있게 남도록 해 인장기를 이용한 인장 제거 편의도 함께 제공되는 그라운드 앵커용 정착체 받침에 관한 것이다.The present invention relates to a support for supporting the outer fixing body to which the outer end of the tension member penetrating the structure such as the earth wall in the tension member removal ground anchor is fixed, in particular, it is easy to cut the outer end of the tension member for releasing the external fixing, The present invention relates to a fixture anchor support for a ground anchor provided with a tension removal convenience using a tensioner so that the outer end of the tensioning material cut out to the outside of a civil structure such as an earth wall is left.

도 1에 예시한 바와 같이, 인장재 제거형 그라운드 앵커는 토류벽(1)의 H파일(2) 안쪽을 가로 지른 띠장(3)의 내측 플랜지(4a) 상에 정착체 받침(5)을 부착하고, 이 정착체 받침(5)에 외부 정착체(6)를 설치하여 그라운드 앵커의 인장재(7) 외측단을 관통시킨 다음에 소정의 압력으로 인장한 후 외부 정착체(6)에 정착하는 방법으로 설치하게 된다. 도면부호 (9)는 토류벽 외곽 지반, (10)은 지반(9)에 천공된 앵커공을 표시한다.As illustrated in FIG. 1, the tension member-removable ground anchor attaches the fixture support 5 on the inner flange 4a of the strip 3 transversely inside the H-pile 2 of the earth wall 1, The external fixture 6 is installed in the fixture support 5 so as to penetrate the outer end of the tension member 7 of the ground anchor, and then tension to a predetermined pressure to fix the external fixture 6 to the external fixture 6. Done. Reference numeral 9 denotes an earth wall outer ground, and 10 denotes an anchor hole drilled in the ground 9.

굴토된 현장(8)에 지하구조물을 구축한 후에는 인접 지반에 대한 그라운드 앵커의 장애물화를 최소화하기 위하여 인장재를 제거하게 된다. 인장재를 제거하려면 정착하중을 해제해야 한다. 통상, 인장재의 정착하중 해제는 보편적으로 토류벽 밖으로 노출된 인장재의 후단부를 용접기로 절단하는 것이다. 인장재의 외측단이 절단되면서 정착하중에 상응하는만큼 수축된다. 절단된 인장재의 외측단은 토류벽 밖 굴착 공간에 잔류하는 부분이 길어야만 인장기에 물려서 제거하기가 쉽 다. 정착하중에 상응하는 인장재의 수축분을 고려하여 인장재의 외측단은 되도록 띠장(3)의 내측 플랜지(4a)에 가까운 부분(A)을 밭게 절단하는 것이 바람직하다. 인장재는 토치를 이용한 산소 아크 절단방법(oxy-arc cutting)으로 절단한다. After constructing the underground structure in the excavated site (8), the tension member is removed to minimize the obstruction of the ground anchor to the adjacent ground. To remove the tension, the anchoring load must be released. Usually, the release of the anchoring load of the tensioning material is to cut the back end of the tensioning material, which is generally exposed out of the earth wall, with a welder. As the outer end of the tension member is cut off, it contracts as much as the fixing load. The outer end of the cut tension member is easy to be removed by biting the tensioner only if the part remaining in the excavation space outside the earth wall is long. In consideration of the shrinkage of the tension member corresponding to the fixing load, it is preferable to cut the portion A close to the inner flange 4a of the strip 3 to the outer end of the tension member. The tension member is cut by oxy-arc cutting using a torch.

통상, 토류벽용 띠장은 그 밑으로 산소 아크 절단기를 들이대서 절단하기에는 밑공간이 좁다. 그래서 대개는 작업편의를 우선 시 하는 바람에 외측 플랜지(4b)에 인접한 부분(B)을 절단하는 데, 그 과정에서 심선을 제외한 6가닥의 소선이 차례로 절단되면서 정착하중에 상응하는만큼 수축되는 바람에 도 2와 같이 절단된 인장재의 후단이 토류벽 쪽으로 바짝 다가서거나 최악의 경우 토류벽 속으로 숨기도 한다. 그리되면 인장기에 인장재의 후단을 물리기 곤란하거나 아예 물릴 수 없어 난처한 상황을 맞게 된다. In general, the earth wall strip has a small space for cutting under the oxygen arc cutting machine. Therefore, in order to give priority to the work piece, the part (B) adjacent to the outer flange (4b) is cut. In the process, the six strands of the strands except the core wire are cut in sequence and contracted as much as the settling load. As shown in FIG. 2, the rear end of the tension member cut close to the earth wall or at worst hides in the earth wall. Then, it is difficult to bite the back end of the tensioner in the tensioner, or it can not be bitten at all, which leads to a difficult situation.

이런 경우, 인장재의 토류판을 제거하거나 인장재 후단 주위의 구멍을 넓히는 방법으로 자구조치를 취한 후 인장기를 동원해 제거하게 되는 데, 실제로 그 작업은 불편하고 더디며, 마무리공정에도 차질이 예상된다.In this case, by removing the earth plate of the tension member or by taking a self-structuring method by widening the hole around the trailing end of the tension member, the tensioner is mobilized to remove it, which is inconvenient and slow, and the finishing process is expected to be disrupted.

따라서 본 발명의 목적은 외부정착을 해제하기 위한 인장재의 후단부가 길게 잔류하여 인장기로 제거하기 쉽게 절단할 수 있는 그라운드 앵커용 정착체 받침을 제공하는 것이다.It is therefore an object of the present invention to provide a fixture anchor support for a ground anchor that can be easily cut off by a tensioner because the rear end of the tension member for releasing external fixation is long.

이 과제는 띠장이나 옹벽 등에 밀착되는 기판과 정착구 설치용 정착판을 일정한 길이를 가진 스페이서봉으로 연결하여 기판과 정착판 사이에 산소 아크 절단기(토치)를 수월하게 들이 대 인장재 후단부가 길게 잔류하도록 절단하는 데 필요 한 토치 출입공간이 확보되도록 한 그라운드 앵커용 정착체 받침으로 달성할 수 있다.The task is to connect the substrate, which is in close contact with the strip or retaining wall, and the fixing plate for fixing fixtures with a spacer rod having a certain length, so that the oxygen arc cutter (torch) is easily cut between the substrate and the fixing plate so that the rear end of the tension member is long. Achievement support for ground anchors ensures that necessary torch access is required.

도 3에서, 본 발명에서 제안하는 그라운드 앵커용 정착체 받침(10)은 기판(20)과 정착판(30) 및 스페이서봉(40)으로 이뤄진다.In FIG. 3, the fixture support 10 for the ground anchor proposed by the present invention includes a substrate 20, a fixing plate 30, and a spacer rod 40.

기판(20)은 토류벽의 H파일이나 그 띠장, 콘크리트 옹벽 등에 밀착되는 것으로, 판면에는 1 또는 2 이상의 인장재가 관통할 인장재공(21)이 천공되어 있고, 가장자리에는 스페이서봉의 핀이 꽂히는 복수의 핀공(22)이 원주피치간격마다 천공되어 있다. The substrate 20 is in close contact with the H-file of the earth wall, its strip, and the concrete retaining wall, and the plate surface is perforated with a tensile material hole 21 through which one or more tension members can penetrate, and a plurality of pin holes into which the pin of the spacer rod is inserted at the edge thereof. (22) is perforated at every circumferential pitch interval.

정착판(30)은 기판(20)과 일정한 거리를 유지하는 가운데 그 위에 탑재되는 외부 정착체를 지지하는 것으로, 기판(20)의 인장재공(21)과 동수의 인장재공(31)이 천공되어 있다. The fixing plate 30 supports the external fixing body mounted thereon while maintaining a constant distance from the substrate 20, and the tensile material hole 21 and the same number of tensile material holes 31 of the substrate 20 are drilled. have.

스페이서봉(40)은 기판(20)과 정착판(30)을 일정한 거리로 유지시켜 그 사이로 드러나는 인장재 부분으로 용이하게 토치를 들이밀어 절단하기 쉽게 한 것으로, 하단에는 상기 핀공(22)에 꽂아 기판(20)과의 조합상태를 유지하게 되는 핀(41)이 형성되어 있다. 기판(20)의 핀공(22)에 핀(41)이 꽂힌 상태에서 기판(20)의 반대방향으로 정착판(30)을 잡아당기면 핀(41)이 뽑힌다. 인장재를 제거할 때 필요하다. Spacer rod 40 is to keep the substrate 20 and the fixing plate 30 at a constant distance to easily cut the torch by pressing the torch to the portion of the tension material exposed therebetween, the lower end is inserted into the pin hole 22 to the substrate The pin 41 which maintains the combined state with the 20 is formed. The pin 41 is pulled out by pulling the fixing plate 30 in the opposite direction of the substrate 20 while the pin 41 is inserted into the pin hole 22 of the substrate 20. Necessary for removing the tension member.

스페이서봉(40)의 상단은 정착판(30)의 저면 가장자리에서 기판(20)의 핀공(22)과 동축선 상에 부착하되 기판(20)과 정착판(30) 사이는 물론 스페이서 봉(40)간에도 토치가 자유롭게 드나들 수 있게 충분한 토치 출입공간(50)을 확보한다. The upper end of the spacer rod 40 is attached coaxially with the pin hole 22 of the substrate 20 at the bottom edge of the fixing plate 30, but between the substrate 20 and the fixing plate 30 as well as the spacer rod 40. Secure enough torch access space 50 to allow the torch to move freely.

여기서, 핀(41)과 핀공(22)을 테이퍼지게 형성하면 곧은 핀과 핀공에 비해 핀 끼워 맞추기, 핀(41)과 핀공(22)의 자동 조심에 의한 평형감, 및 핀 빼기가 수월하다. Here, when the pin 41 and the pin hole 22 are tapered, the pin fitting, the balance between the pin 41 and the pin hole 22 by self-aligning, and the pin removal are easier than those of the straight pin and the pin hole.

한편, H빔제 띠장에 설치되는 것은 종래의 무스페이서봉형 정착제 받침에 비해 스페이서봉(40)이 개입된 정착체 받침(10)은 그 정착판(30)이 훨씬 더 멀리 위치하므로 토치를 들이대기 수월해서 짧은 스페이서봉(40)을 적용해도 무방하지만, 띠장이 필요치 아니한 콘크리트 옹벽이나 슬러리 월의 경우에는 띠장의 폭이 더해진 스페이서봉(40)으로 해야만 본 발명에서 의도한 목적을 구현할 수 있다. 이처럼 스페이서봉(40)은 정착체 받침(10)의 용처에 따라 길이를 달리 책정하는 것을 원칙으로 한다. On the other hand, it is installed in the H-beam strip is a fixture support 10 in which the spacer rod 40 is interposed compared to the conventional spacer-free fixer support, because the fixing plate 30 is located far farther in the torch Although it may be easy to apply a short spacer rod 40, in the case of a concrete retaining wall or slurry wall that does not require a belt length, only the spacer rod 40 to which the width of the band length is added can achieve the object intended in the present invention. As such, the spacer rod 40 has a length that is determined in principle according to the usage of the fixture support 10.

도 4는 정착판(30a)이 웨지블록을 겸한 정착체 받침의 변경실시예를 나타낸 것이다. 웨지블록 겸용 정착판(30a)은 외부 정착체의 길이가 더해진 정도로 두꺼운 강판제로 하고, 인장재공 자리에 웨지좌(32)를 형성하여 외부 정착체용 웨지블록이 하던 기능을 대행하게 한 것으로, 개별적으로 웨지블록을 가공하여 부착하던 불편을 덜 수 있다. Figure 4 shows an embodiment of the fixing plate (30a) is a fixture support serving as a wedge block. Wedge block combined fixing plate (30a) is made of a steel sheet thick enough to add the length of the external fixture, and formed a wedge seat 32 in the tension seat position to act as a function of the wedge block for the external fixture, individually Wedge blocks can be processed and attached to reduce the inconvenience.

그리고 상기 기판(20)은 저면의 각도에 따라 평면형과 빗면형으로 나뉜다. 평면형 기판(20)은 도 5에 예시한 바와 같이 그라운드 앵커가 설치될 지반의 지면(60)이 그라운드 앵커의 기울기와 직각을 이뤄서 인장재 후단부가 꺾일 우려가 없는 곳에 적용하는 데 적합하고, 도 6에 나타난 바와 같이 저면(23)이 빗면으로 된 기판(20a)은 앞면이 토류벽의 엄지말뚝이나 띠장, 수직인 슬러리 월, 콘크리트 옹벽(1a) 등에 설치된 정착체 받침(10)과 인장재(7)의 각도가 직각이 아니어서 인장재 후단부의 꺾임이 예상되는 곳에 적합하다.The substrate 20 is divided into a planar shape and an inclined plane shape according to the angle of the bottom surface. As shown in FIG. 5, the planar substrate 20 is suitable for application where the ground 60 of the ground on which the ground anchor is to be installed is perpendicular to the inclination of the ground anchor so that the rear end portion of the tension member may not be bent. As shown, the substrate 20a having the bottom surface 23 as the inclined surface has an angle between the fixture support 10 and the tension member 7 installed on the thumb pile or strip of the earth wall, the vertical slurry wall, and the concrete retaining wall 1a. It is suitable where the bending of the trailing end is not expected because it is not at right angles.

도 7에 예시한대로, 옹벽(1a)에 본 발명의 정착체 받침(10)을 설치하고 그라운드 앵커의 인장재 외측단을 정착시켰다가 소기의 목적을 달성하고 정착판(30)에 가까운 토치 출입공간(50)으로 토치를 들이 밀어 정착판(30)에 가까운 곳을 절단했을 때 정착하중에 상응하는만큼 인장재가 수축되더라도 인장재 후단부(7a)는 옹벽(1a)의 앞쪽에 충분한 길이로 잔류하게 돼 기판(20)에 곧바로 인장기를 비치하고 거기다 인장재 후단부(7a)를 끼워 물리기 쉬우므로 인장재를 제거하기가 한결 용이해진다. 기판(20)은 인장재가 제거된 후에 철거한다.As illustrated in FIG. 7, the fixture base 10 of the present invention is installed on the retaining wall 1a, and the tension member outer end of the ground anchor is fixed to achieve the desired purpose. 50) When the torch is pushed into the cutting plate 30 to cut the portion close to the fixing plate 30, even if the tension member shrinks as much as the fixing load, the rear end portion 7a of the tension member remains at a sufficient length in front of the retaining wall 1a. A tensioner is immediately provided at (20), and a tensioner rear end portion 7a is easily fitted into the tensioner, which makes it easier to remove the tensioner. The substrate 20 is demolished after the tension member is removed.

이상 설명한 대로 본 발명의 그라운드 앵커용 정착체 받침은 띠장, H파일, 옹벽 등의 안정용으로 설치된 인장재 제거형 그라운드 앵커에서 띠장, H파일, 옹벽 등의 앞쪽으로 노출된 인장재의 후단부가 길게 잔류하여 인장기로 제거하기 쉽도록 정착판 쪽으로 밭게 절단하기가 아주 용이하다.As described above, in the anchor anchor support of the present invention, the rear end portion of the tension member exposed to the front of the strip, H pile, retaining wall, etc. in the tension member removal type ground anchor provided for stability of the strip, H pile, retaining wall, etc. It is very easy to cut into the fixing plate toward the fixing plate so that it is easy to remove with a flag.
