Description
본 발명은 토목공사 등에서 연약 지반을 보강하기 위한 앵커공법에 사용되는 인장재의 체결 및 해체장치에 관한 것으로서, 보다 상세하게는 앵커에 인장재를 체결하여 고정하고 사용 후 해체하여 인장재를 제거할 수 있으며, 또한 부주의로 인하여 인장재가 앵커로부터 해체되더라도 다시 체결하여 고정할 수 있는 앵커공법용 인장재의 체결 및 해체장치에 관한 것이다.The present invention relates to a fastening and dismantling device of the tension member used in the anchoring method for reinforcing the soft ground in civil engineering, etc. More specifically, it is possible to remove the tension member by fastening the tension member to the anchor and dismantle it after use. The present invention also relates to a fastening and dismantling device of an anchoring method for the anchoring method, which can be refastened and fixed even if the tension member is dismantled from the anchor due to carelessness.
앵커공법은 흙막이공사, 터널갱구부 안정용, 석축 및 옹벽보강용 등의 토목공사에서 연약한 지반을 보강하는데 사용되는 공법이다. 이 공법과정은 먼저, 인장재의 한쪽끝단에 앵커공법용 인장재의 해체장치를 체결한 후 인장재에 그라우트호스(grout hose)를 고정시킨 내하체를 마련한다.The anchor method is a method used to reinforce the soft ground in civil works such as retaining works, stabilizing tunnel shafts, reinforcing stones and retaining walls. In this process, first, the dismantling device for the anchoring method is connected to one end of the tensioning member, and then a load bearing body having a grout hose fixed to the tensioning member is prepared.
이 내하체를 현장으로 운반한 후 천공기에 의해 천공된 지중의 구멍으로 삽입한 다음, 그라우트호스를 통해 그라우트(grout)를 주입하고 주입된 그라우트가 내하체와 양생되면 상기 인장재의 다른 한쪽끝단 또한 앵커공법용 인장재의 해체장치를 체결한 후 인장기로 인장재를 당겨 그라우트와 지면은 물론 인장재에 최대의 인장력이 작용하도록 시공 설치하는 것으로서 연약한 지면을 보강하는 공법으로서 토목공사에서 주로 사용되어지는 공법이다.After transporting the inner body to the site and inserting it into a hole in the ground drilled by a perforator, grout is injected through the grout hose, and when the injected grout is cured with the inner body, the other end of the tension member is anchored It is a construction method to reinforce the soft ground by installing the construction to make the maximum tensile force act on the grout and the ground as well as the ground by pulling the tension member with the tensioner after the dismantling device of the tension member for the construction method.
그러나, 도심지공사에서 앵커공법의 적용은 효과적인 시공관리 및 공기단축 등의 장점이 있으나 인접지대에 대한 추후공사시 일반철근의 강도에 비해 단면적 상 강도가 약6배인 인장재의 가설로 인해 굴착장비 및 천공장비의 손실과 공기지연이 발생한다. 따라서 굴착공사 완료 후 건축공정에 맞추어 인장재를 제거할 수 있는 제거앵커가 사용되는데 이것이 앵커공법에서 사용되는 인장재의 해체장치이다.However, the application of anchor method in urban construction has advantages such as effective construction management and shortening of air. However, the construction of drilling equipment and drilling is performed due to the hypothesis of tensile material having about 6 times the cross-sectional strength compared to that of general reinforcing bars in subsequent construction of adjacent areas. Equipment loss and air delays occur. Therefore, the removal anchor used to remove the tension member in accordance with the construction process after completion of excavation work is used, which is the dismantling device of the tension member used in the anchor method.
종래의 앵커공법에 사용되는 인장재의 해체장치는 도 1에 나타낸 바와 같이, 중앙에 인장재(100)가 삽입되어 고정될 수 있는 고깔형의 웨지유닛(200)과, 이 고깔형의 웨지유닛(200)을 수용하는 웨지수용공간을 갖는 본체(300), 상기 웨지유닛 (200) 상부의 환형 홈에 삽입되어 인장재(100)의 끝단을 지지하는 지지판재(400)가 형성되고 이 지지판재(400)의 상부로 돌출 형성된 해체나사(500), 상기 본체(300)의 상단에 체결되고 내부에 암나사가 형성된 캡(600)으로 구성되어 있다.As shown in Figure 1, the dismantling device of the tension member used in the conventional anchor method, the wedge unit 200 of the solid type that can be fixed by inserting the tension member 100 in the center, and the wedge unit 200 of the solid type The main body 300 having a wedge accommodation space for accommodating), and a support plate member 400 inserted into the annular groove of the upper portion of the wedge unit 200 to support the end of the tension member 100 is formed and the support plate member 400 The disassembly screw 500 is formed to protrude to the upper portion of the main body 300 is fastened to the upper portion of the cap 600 is formed with a female screw formed therein.
상기와 같이 구성된 종래의 앵커공법용 인장재의 해체장치는 도 1과 같이 인장기를 이용하여 웨지유닛(200)에 인장재(100)를 인장시킨 상태로 지중에 매설되어 있고 이러한 상태에서 인장재(100)를 절단한 후 인장재(100)를 회전시킨다. 이와 같이 인장재(100)가 절단되어도 웨지유닛(200)에 파지 고정되어 있는 상태이므로 인장재(100)의 회전에 따라 도 2와 같이 인장재(100)의 끝단과 접촉된 해체나사(500)가 회전되고 따라서 해체나사(500)는 캡(600)의 홈으로 회전 삽입되어 웨지유닛(200)으로부터 인장재(100)의 구속이 해제되게되며 이렇게 인장재(100)의 구속이 해제되면 인장재(100)를 잡아당겨 빼냄으로써 해체가 완료되는 것이다.Conventional dismantling device of the anchoring method configured as described above is buried in the ground in the state of tensioning the tension member 100 in the wedge unit 200 using a tensioner as shown in Figure 1 and in this state tension member 100 After cutting, the tension member 100 is rotated. As such, even when the tension member 100 is cut, the disassembly screw 500 in contact with the end of the tension member 100 is rotated as shown in FIG. 2 due to the rotation of the tension member 100. Accordingly, the dismantling screw 500 is inserted into the groove of the cap 600 to release the restraint of the tension member 100 from the wedge unit 200. When the restraint of the tension member 100 is released, the tension member 100 is pulled out. By disassembly, the dismantling is completed.
그러나, 종래 앵커공법용 인장재의 해체장치에 있어서는 웨지유닛(200)과 해체나사(500)와의 공회전을 방지하기 위한 수단이 없는 구조적인 특성으로 인하여 인장재(100)의 절단 후 인장재를 회전시키더라도 인장재(100)의 끝단이 접촉되는 지지판재(400)에서 인장재(100)만 공회전하고 해체나사(500)를 회전시키지 못하는 경우가 발생되기 쉬운 것이었다.However, in the conventional anchorage dismantling device of the anchoring method, even if the tension member is rotated after cutting the tension member 100 due to the structural characteristics without means for preventing idle rotation between the wedge unit 200 and the dismantling screw 500. In the support plate member 400 in which the end of the 100 is in contact, only the tension member 100 is idling and the disassembly screw 500 cannot be easily rotated.
특히, 인장재(100)의 인장시 발생되는 인장력은 인장재(100)를 절단할 시 강한 반발력으로 작용하여 해체나사(500)가 캡(600)의 홈을 강타하게 되고 이로 인하여 캡(600)의 홈 및 웨찌나사(500)의 소성변형이 발생되면 인장재(100)를 회전시키더라도 인장재(100)만이 회전되는 공회전의 원인이 되었으며, 이러한 경우에는 인장재(100)의 제거가 곤란하다는 문제점이 발생하였다.In particular, the tensile force generated during tensioning of the tension member 100 acts as a strong repulsive force when cutting the tension member 100 so that the dismantling screw 500 hits the groove of the cap 600 and thereby the groove of the cap 600 And when the plastic deformation of the wedge screw 500 occurs, even when the tension member 100 is rotated, it causes the idle rotation of only the tension member 100, in this case, the problem that the removal of the tension member 100 is difficult.
또한 인장재(100)와 본체(300)를 마무리하는 부분(가)은 나사결합에 의해 이루어진 것인바 공사지연이나 지중에 매설 후 그라우트 양생기간에 물이 침투하기 쉽고 물이 침투하면서 발생되는 녹으로 인해 인장재를 제거할 때 실패의 한 요인이 되는 문제점이 발생하였다.In addition, the part (a) which finishes the tension member 100 and the main body 300 is made by screwing, which is easy to penetrate during grout curing period after laying in construction delay or underground, and due to rust generated by water infiltration. When removing the tension member, a problem that caused a failure occurred.
본 발명의 목적은 상기와 같은 종래의 제반 문제점을 해결하기 위하여 연구 개발한 것으로서, 인장재가 인장된 설치상태에서 인장재의 절단시 발생되는 반발력을 이용하여 절단된 인장재가 웨지유닛을 단턱봉 쪽으로 밀어 올려 웨지유닛 상단의 걸림턱이 단턱봉의 단턱에 자연스럽게 결합시키며 이렇게 웨지유닛과 단턱봉이 결합되면서 웨지유닛의 웨지들이 벌어져 인장재의 고정이 해제되므로 별도의 추가작업이 필요 없이 인장재를 제거할 수 있도록 한 앵커공법용 인장재의 체결 및 해체장치를 제공하는데 있다.An object of the present invention has been researched and developed in order to solve the conventional problems as described above, the tension member is cut by using the repulsive force generated when cutting the tension member in the tensioned installation state is pushed up the wedge unit toward the jaw bar The locking jaw of the top of the wedge unit is naturally coupled to the step of the step bar. As the wedge unit and the step bar are combined, the wedge of the wedge unit opens and the tension member is released so that the anchor member can be removed without additional work. The present invention provides a device for fastening and dismantling a tension member.
본 발명의 다른 목적은 3개의 웨지로 분할된 웨지유닛이 스프링에 의해 탄력적으로 설치되어 있어 작업시 부주의에 따라 인장재가 웨지유닛으로부터 해제되더라도 다시 인장재를 넣고 타격하면 스프링의 복원력으로 인하여 웨지유닛이 웨지수용공간의 원래위치로 복귀되게되며 이렇게 복귀된 상태에서 웨지유닛에 인장재를 고정시켜 재사용할 수 있도록 한 앵커공법용 인장재의 체결 및 해체장치를 제공하는데 있다.Another object of the present invention is that the wedge unit divided into three wedges are elastically installed by the spring, even if the tension member is released from the wedge unit due to carelessness during operation, the wedge unit is wedge due to the restoring force of the spring when the tension member is put back and hit. It is to provide a fastening and dismantling device of the anchoring method for the anchoring method to be returned to the original position of the receiving space and to be reused by fixing the tension member to the wedge unit in the returned state.

이하, 본 발명의 앵커공법용 인장재의 체결 및 해체장치를 첨부된 도면에 의거 상세하게 설명하고자 한다.Hereinafter, the fastening and dismantling device of the tension member for anchor method of the present invention will be described in detail based on the accompanying drawings.
도 3 내지 도 5는 본 발명에 따른 앵커공법용 인장재의 체결 및 해체장치를 설명하기 위해 나타낸 도면들이다.3 to 5 are diagrams for explaining the fastening and dismantling device of the tension member for anchor method according to the present invention.
도면에 나타낸 바와 같이, 본 발명의 장치는 본체(60)의 웨지수용공간(61)에 웨지유닛(20)이 안착 설치되며 이 웨지유닛(20)을 본체(60)의 웨지수용공간(61)으로 항시 밀도록 스프링(90)이 탄력적으로 설치되고 상기 본체(60)상단의 캡 체결나사(62)에 웨지유닛(20)과 스프링(90)의 이탈을 방지하도록 나사 결합되는 캡(70)으로 구성된다.As shown in the figure, in the apparatus of the present invention, the wedge unit 20 is seated and installed in the wedge accommodation space 61 of the main body 60, and the wedge unit 20 is installed in the wedge accommodation space 61 of the main body 60. Spring 90 is elastically installed so as to always push to the cap 70 is screwed to prevent the wedge unit 20 and the spring 90 is separated from the cap fastening screw 62 of the upper portion of the main body 60 to It is composed.
상기 본체(60)는 상하로 개구되되 적어도 상부에 콘형의 웨지수용공간(61)이 형성되고 상단외면에 캡 체결나사(62)가 형성되어 있으며, 상기 본체(60)의 하부에는 인장재(10)가 삽입되더라도 기밀이 유지되도록 외측에 씌워진 플라스틱 튜브(54)와 그 끝단의 고깔 콘(55)으로 마감 처리되어 있다. 상기 플라스틱튜브(54)와 고깔 콘(55)은 본체(60)와 캡(70)의 내부로 물이 침투하는 것을 방지하는 방수효과와 이로 인한 녹 방지 역할을 한다.The main body 60 is opened up and down, at least a cone-shaped wedge accommodation space 61 is formed at the top and the cap fastening screw 62 is formed on the upper outer surface, the tension member 10 in the lower portion of the main body 60 Even if the insert is closed with a plastic cone (54) covered with the outer side and the solid cone 55 of the end so that the airtight is maintained. The plastic tube 54 and the solid cone 55 serves to prevent water from penetrating into the body 60 and the cap 70 and to prevent rust.
상기 웨지유닛(20)은 중앙에 하나의 원을 이루어 인장재(10)가 삽입될 수 있는 홀을 갖도록 3개의 웨지가 하나의 콘형을 이루고 상기 홀 상부의 환형 링에 끼워진 지지판재(30)를 중심으로 하여 외면의 고무 링(50)이 3개의 웨지들을 확장시키도록 마련된다. 상기 웨지유닛(20)의 홀 상단에는 후술되는 단턱봉(80)의 단턱(81)과 걸리도록 걸림턱(21)이 형성되어 있고 상기 홀 내면에는 나선형 내지 톱니형의 요철이 형성되어있어 인장재(10)를 인장시킬 때 웨지유닛(20)에서 인장재(10)가 미끄러지거나 이탈됨을 방지하는 역할을 한다.The wedge unit 20 forms a circle in the center so that the three wedges form one cone shape so as to have a hole into which the tension member 10 can be inserted, and the center of the support plate member 30 fitted in the annular ring on the upper portion of the hole. The outer rubber ring 50 is provided to expand the three wedges. At the upper end of the hole of the wedge unit 20, the engaging jaw 21 is formed to be caught with the stepped 81 of the stepped rod 80, which will be described later. When tensioning 10) serves to prevent the tension member 10 in the wedge unit 20 slip or slip.
상기 웨지유닛(20)의 걸림턱(21)과 단턱봉(80)의 단턱(81)이 도 4,5와 같이 직각으로 형성된 것으로 도시하고 설명하였으나 이 경우는 단턱(81)을 0.5∼1㎜정도의 작게 형성하여 걸림 해제동작의 확보되어야 한다. 따라서, 웨지유닛(20)의 걸림턱(21)과 단턱봉(80)의 단턱(81)을 서로 상응하여 맞닿는 소정의 경사각도로 형성시킴이 바람직하며, 그 이유는 웨지유닛(20)이 단턱봉(80)의 단턱(81)으로부터 보다 용이하게 해제되도록 하기 위해서이다.Although the locking step 21 and the stepping step 81 of the stepping rod 80 of the wedge unit 20 are illustrated and described as being formed at right angles as shown in FIGS. 4 and 5, in this case, the stepping step 81 is 0.5 to 1 mm. It should be formed small enough to secure the locking release operation. Therefore, it is preferable to form the engaging jaw 21 of the wedge unit 20 and the stepped jaw 81 of the stepped bar 80 at a predetermined inclination angle to abut each other, for the reason that the wedge unit 20 has the stepped bar. This is for the release from the step 81 of 80 more easily.
상기와 같이 구성된 본 발명의 앵커공법용 인장재의 체결 및 해체장치는 본체(60) 하부의 구멍으로부터 인장재(10)를 타격하면서 삽입하면 인장재(10)의 한쪽끝단에 의해 웨지유닛(20)가 밀리면서 순간적으로 벌어질 때마다 삽입된다. 이때, 인장재(10)의 끝단이 웨지유닛(20)의 지지판재(30)에 닿을 때까지 삽입한다. 이렇게 본 고안의 앵커공법용 인장재의 체결 및 해체장치를 체결한 인장재(10)에 그라우트호스(grout hose)를 고정시킨 내하체를 마련한다. 이 내하체를 천공기에 의해 천공된 지중의 구멍으로 삽입한 다음, 그라우트호스를 통해 그라우트(grout)를 주입하고 주입된 그라우트가 내하체와 양생되면 상기 인장재(10)의 다른 한쪽끝단 또한 앵커를 체결한 후 인장재(10)를 인장기로 당겨 그라우트와 지면은 물론 인장재(10)에 최대의 인장력이 작용하도록 시공 설치된다.The fastening and dismantling device for the anchoring method of the present invention configured as described above is inserted while hitting the tension member 10 from the hole in the lower body 60, the wedge unit 20 is pushed by one end of the tension member 10 It is inserted every time it opens. At this time, the end of the tension member 10 is inserted until it reaches the support plate member 30 of the wedge unit 20. Thus, a load-bearing body having a grout hose fixed to the tension member 10 in which the fastening and dismantling device of the anchoring method of the present invention is fastened is provided. The inner body is inserted into a hole in the ground drilled by a perforator, and then grout is injected through the grout hose, and when the injected grout is cured with the lower body, the other end of the tension member 10 also fastens the anchor. After pulling the tension member 10 to the tensioner is installed in the construction so that the maximum tensile force acts on the grout and the ground as well as the tension member 10.
이러한 상태에서 외부로 인출된 부분의 인장재(10)를 절단하게되면 인장재(10)에 가해졌던 인장력이 해제됨과 아울러 그동안 인장재(10)에 걸려있던 장력에 대한 반작용으로 인장재(10)는 캡(70) 쪽으로 나아간다.When the tension member 10 of the portion drawn out in such a state is cut, the tension force applied to the tension member 10 is released and the tension member 10 is in response to the tension applied to the tension member 10. To the side.
이렇게 인장재(10)가 퉁겨나갈 때 지지판재(30)에 의해 걸리므로 웨지유닛(20)을 이끌고 나아가게 되고 웨지유닛(20)은 고무 링(50)에 의해 지지판재(30)을 중심으로 하여 웨지유닛(20)의 웨지들이 벌어지면서 나아가 웨지유닛(20)상단의 걸림턱(21)이 단턱봉(80)의 단턱(81)을 수용함으로써 단턱봉(80)의 단턱(81)에 웨지유닛(20)가 걸려 잠기게 된다. 이때에는 웨지유닛(20)의 웨지들이 벌어진 상태이므로 인장재(10)를 물고 있던 웨지로부터 해제되게 되고 이렇게 본체(60)내의 웨지유닛(20)에서 해제된 인장재(10)는 인력으로 잡아당겨 빼낼 수 있는 상태인바 아주 손쉽게 인장재(10)를 제거할 수 있는 것이다.When the tension member 10 is squeezed by the support plate 30, the wedge unit 20 is led and moved along the wedge unit 20. The wedge unit 20 is wedge around the support plate 30 by the rubber ring 50. As the wedges of the unit 20 are opened, the wedge unit 20 of the upper end of the wedge unit 20 receives the stepped jaw 81 of the stepped rod 80 so that the wedge unit ( 20) is locked and locked. At this time, since the wedges of the wedge unit 20 are opened, the tension member 10 is released from the wedge that is biting. Thus, the tension member 10 released from the wedge unit 20 in the main body 60 can be pulled out by the attraction force. It is in a state that can remove the tension member 10 very easily.
상기와 같이 인위적으로 인장재가 해제된 경우가 아니고 작업부주의로 인하여 인장재가 해제된 경우에는 인장재(10)를 타격하면 인장재(10)의 끝단이 웨지유닛(20)의 지지판재(30)을 밀치고 들어갔다가 스프링(90)이 갖는 복원력(탄발력)으로 인하여 단턱봉(80)의 단턱(80')으로부터 웨지유닛(20)의 걸림턱(40)이 해제되어본체(60)의 웨지수용공간(61)으로 웨지유닛(20)이 초기상태로 복귀되게 된다.As described above, when the tension member is not artificially released and the tension member is released due to the work caution, the end of the tension member 10 pushes the support plate member 30 of the wedge unit 20 when the tension member 10 is hit. Due to the restoring force (elastic force) of the spring 90, the locking jaw 40 of the wedge unit 20 is released from the step 80 ′ of the stepped rod 80 and the wedge accommodation space 61 of the main body 60 is removed. The wedge unit 20 is returned to the initial state.
따라서, 상기에서 언급한 바와 같이 앵커를 이루는 본체(60)의 웨지유닛(20)에 다시 인장재(10)를 타격하여 밀어 넣음으로써 웨지유닛(20)에 다시 인장재(10)를 고정시킬 수 있어 재사용이 가능하게 된다.Therefore, as mentioned above, the tension member 10 may be fixed to the wedge unit 20 again by hitting and pushing the tension member 10 back into the wedge unit 20 of the main body 60 that forms the anchor. This becomes possible.
도 6 및 도 7은 본 발명의 다른 실시 예에 따른 앵커공법용 인장재의 체결 및 해체장치를 나타낸 도면으로서, 웨지유닛(20)상단과 스프링(90) 사이에는 웨지유닛(20)의 이탈방지와 원활한 동작을 확보하도록 하면은 웨지상면과 상응하는 경사면으로 형성되고 상면은 스프링(90)이 안착되는 단턱이 형성된 압축커버(95)가 부가 설치된 것을 제외하고는 본 발명의 구성과 동일하다.6 and 7 is a view showing the fastening and dismantling device of the anchoring method for the anchoring method according to another embodiment of the present invention, between the top of the wedge unit 20 and the spring 90 prevents the separation of the wedge unit 20 and To ensure a smooth operation is formed in the inclined surface corresponding to the upper surface of the wedge and the upper surface is the same as the configuration of the present invention, except that the compression cover 95 is provided with a stepped seat is installed on the spring 90.
상기와 같은 다른 실시 예의 구성에 의하면, 도 6과 같이 웨지유닛(20)에 인장재(10)가 고정되거나 도 7과 같이 웨지유닛(20)으로부터 인장재(10)가 해제되는 동작이 이뤄질 때 압축커버(95)의 하면에 의해 웨지유닛(20)의 웨지들을 모아주기 때문에 웨지유닛(20)의 웨지들이 이탈됨을 방지하고 원활한 동작을 확보할 수 있는 것이다.According to the configuration of another embodiment as described above, the compression cover when the tension member 10 is fixed to the wedge unit 20 as shown in FIG. 6 or when the tension member 10 is released from the wedge unit 20 as shown in FIG. 7. Since the wedges of the wedge unit 20 are collected by the lower surface of the 95, the wedges of the wedge unit 20 can be prevented from being separated and a smooth operation can be secured.
이상에서 살펴본 바와 같이 본 발명에 따른 앵커공법용 인장재의 체결 및 해체장치는 인장된 인장재의 절단시 발생되는 반발력을 이용하여 절단된 인장재가 웨지유닛을 단턱봉 쪽으로 밀어 올리기 때문에 웨지유닛 상단의 탄성후크와 단턱봉의 단턱이 자연스럽게 결합시키며 이렇게 웨지유닛과 단턱봉이 결합되면서 웨지유닛의웨지들이 벌어져 인장재의 고정이 해제되므로 별도의 추가작업이 필요 없이 인장재를 제거할 수 있다.As described above, the anchoring and dismantling device for the anchoring method according to the present invention is an elastic hook of the upper end of the wedge unit because the tensioning material is pushed up the wedge unit toward the stepped bar by using the repulsive force generated when cutting the tensioned tensile material. As the stepped bar and the stepped bar is naturally combined, and thus the wedge unit and the stepped bar are combined, the wedge of the wedge unit is opened and the tension member is released so that the tension member can be removed without any additional work.
또한 본 발명은 3개의 웨지로 분할된 웨지유닛이 스프링에 의해 탄력적으로 설치되어 있어 작업시 부주의에 따라 인장재가 웨지유닛으로부터 해제되더라도 다시 인장재를 넣고 타격하면 스프링의 복원력으로 인하여 웨지유닛이 웨지수용공간의 원래위치로 복귀되게되며 이렇게 복귀된 상태에서 웨지유닛에 인장재를 고정시켜 재사용할 수 있다.In addition, the present invention is that the wedge unit divided into three wedges are elastically installed by the spring, even if the tension member is released from the wedge unit inadvertently during operation, if the wedge unit is put into the wedge unit due to the restoring force of the spring when hitting the tension member again, It will be returned to its original position and can be reused by fixing the tension member to the wedge unit in this returned state.
