본 발명은 매립형앵커구조구조(100)에 관한 것으로서 보다 상세하게는 교량의 교각 및 교대에 설치되어 교량점검로(200) 등과 같은 구조물을 부착할 때에 교량 내부 철근의 간섭을 피해 설치가 용이하게 하여 시공비를 절감하는 매립형앵커구조(100) 및 시공방법에 관한 것이다.The present invention relates to a buried anchor structure structure 100, and more particularly, it is installed on the bridge piers and abutments to facilitate installation avoiding the interference of reinforcing bars inside the bridge when attaching structures such as the bridge inspection path 200 It relates to a buried anchor structure 100 and a construction method to reduce the construction cost.

일반적으로 교량을 설치한 후, 교량을 지지하고 있는 교각 및 교대에는 여러가지 구조물이 설치되는바, 특히 교량의 슬래브 하부에 설치되는 교량 받침 등을 점검하기 위하여 교량점검로(200)가 설치된다.In general, after installing the bridge, various structures are installed on the piers and abutments supporting the bridge, and in particular, a bridge inspection path 200 is installed to check the bridge bearings installed under the slab of the bridge.

상기한 교량점검로(200) 등과 같은 구조물을 고정설치하기 위해서는 통상적으로 후천공 앵커인 세트앙카를 주로 사용한다.In order to fix and install structures such as the above-described bridge inspection path 200, a set anchor, which is usually a post-drilled anchor, is mainly used.

상기한 세트앙카는 교량에 일정한 깊이로 천공한 후 앵커를 삽입하여 구조물을 결합시켜 고정한다.The set anchor described above is fixed to the structure by inserting an anchor after drilling to a certain depth in the bridge.

그러나 세트앙카를 설치하기 위해서 교각에 천공을 하면, 주철근 및 코핑부 손상이 발생하여 교량의 안정성에 문제가 발생할 수 있으며, 또한 세트앙카를 설치하면 교량 내부의 주철근과는 연결되지 않은 상태에서 표면의 콘크리트에만 결합되기 때문에 중량이 큰 구조물을 결합시키면 교량의 콘크리트에 균열이 발생될 우려가 있다.However, if a pier is drilled in order to install a set anchor, damage to the main reinforcing bar and coping may occur, which may cause problems in the stability of the bridge. In addition, if a set anchor is installed, the surface is not connected to the main reinforcing bar inside the bridge. Since it is only bonded to concrete, there is a risk of cracking in the concrete of the bridge when a heavy structure is bonded.

이러한 문제점을 해결하기 위한 기술은 특허문헌(한국등록 실용 20-0362688호)에 공지되어 있다.A technique for solving this problem is known in the patent document (Korean Registered Utility No. 20-0362688).

한국등록 실용 20-0362688호 교각용 앵커구조는 매립플레이트(1)에 너트부(2), 고정부(4)가 일체로 형성된 교각용 앵커 구조를 제공하였다.Korean Registered Utility No. 20-0362688 Anchor structure for piers provided an anchor structure for piers in which a nut portion 2 and a fixing portion 4 were integrally formed on a buried plate 1.

상기 일체형 교각용 앵커 구조는 앵커의 고정부(4)가 주철근 위치에 설치될 경우에는 철근에 간섭 등 시공할 수 없는 문제점 및 한계가 있다.The integrated pier anchor structure has problems and limitations that cannot be constructed such as interference with the reinforcing bar when the fixing part 4 of the anchor is installed at the position of the main reinforcing bar.

매립플레이트(102)에 결합되는 수평슬라이드레일(103)과 수직슬라이드레일(104)은 롱너트(101)를 피하여 매립플레이트(102) 뒷면에 결합한다.The horizontal slide rail 103 and the vertical slide rail 104 coupled to the buried plate 102 are coupled to the rear side of the buried plate 102 to avoid the long nut 101.

수평슬라이드레일(103), 수직슬라이드레일(104)의 내부공간은 철근결합용볼트(105)와 철근결합용너트(106)가 좌우, 상하 이동이 가능하도록 적절한 공간이 형성되는 것이 바람직하다.The internal space of the horizontal slide rail 103 and the vertical slide rail 104 is preferably formed with an appropriate space so that the rebar coupling bolt 105 and the rebar coupling nut 106 can move left and right.

수평슬라이드레일(103) 및 수직슬라이드레일(104) 의 "ㄱ" 자 플레이트(108)는 강재 및 비철금속이고 안쪽으로 대향되게 마주보고 결합되며, 철근결합용볼트(105)가 조립되는 너트(106) 폭보다 "ㄱ" 자 플레이트(108)의 양끝단부 거리가 짧아 철근결합용볼트(105)가 이탈되지 않아야 한다.The horizontal slide rail 103 and the vertical slide rail 104 of the "a"-shaped plate 108 are steel and non-ferrous metals and are coupled to face to face inward, and the nut 106 to which the reinforcing bolts 105 are assembled Since the distance between both ends of the "a"-shaped plate 108 is shorter than the width, the reinforcing bolts 105 should not be separated.

미리 설계된 롱너트(101) 위치에서 선시공된 철근(400)과 간섭이 안되기 위하여 철근결합용볼트(105)가 조립되는 너트(106)를 수평슬라이드레일(103) 또는 수직슬라이드레일(104) 위에서 움직여서 철근결합용볼트(105)를 체결한 후 철근(400)에 용접하여 고정하며, 또는 다른 방법으로 고정하여 콘크리트 몰탈 타설 시 매립형앵커구조(100)가 움직이지 않게 하는 것이 바람직하다.In order not to interfere with the pre-built reinforcing bar 400 at the position of the pre-designed long nut 101, the nut 106 to which the reinforcing bar coupling bolt 105 is assembled is moved on the horizontal slide rail 103 or the vertical slide rail 104. After fastening the reinforcing bolts 105, it is preferable to weld and fix the reinforcing bar 400, or to fix it in another way so that the buried anchor structure 100 does not move during concrete mortar pouring.

철근결합용볼트(105)는 강재이며, 시장 생산품을 사용하는 것이 바람직하다.The reinforcing bar coupling bolt 105 is a steel material, and it is preferable to use a market product.

매립형앵커구조(100) 시공 방법 관련하여 바람직한 실시예인 도 11를 참조하면, 1단계는 설계도면에 의거 철근(400) 배근을 완료해야 하며, Referring to FIG. 11, which is a preferred embodiment with respect to the buried anchor structure 100 construction method, step 1 must complete reinforcement of the reinforcing bar 400 according to the design drawing,

2단계는 바람직한 실시예인 도 12에 예시된 것처럼 철근(400) 배근의 외부로 롱너트(101)를 설계에 지시된 위치에 선정하고 수평슬라이딩레일(103) 또는 수직슬라이딩레일(104) 중 철근(400)간섭이 되지 않는 위치로 철근결합용볼트(105)가 조립되는 너트(106)를 이송한 후 철근결합용볼트(107)를 조립한 다음 철근(400)에 용접하거나 결속시키는 것이 바람직하다.In the second step, as illustrated in FIG. 12, which is a preferred embodiment, the long nut 101 is selected at the position indicated in the design to the outside of the reinforcing bar 400, and the reinforcing bar (out of the horizontal sliding rail 103 or the vertical sliding rail 104) ( 400) After transporting the nut 106 to which the reinforcing bolts 105 are assembled to a position where there is no interference, it is preferable to assemble the reinforcing bolts 107 and then weld or bind to the reinforcing bar 400.

3단계는 거푸집(600)을 해체하고 롱너트(101)의 고무마게를 제거한다.In the third step, the formwork 600 is dismantled and the rubber mage of the long nut 101 is removed.

4단계는 교량점검로(200) 등과 같은 구조물을 결합시키기 위해서는 롱너트(101)에 점검로조립용볼트(107)로 구조물(200)를 결합시키면 되는 것이다.In step 4, in order to couple structures such as the bridge inspection path 200, the structure 200 can be coupled to the long nut 101 with the inspection path assembly bolt 107.

상기한 매립형앵커구조(100)는 시공이 간편하여 설치비를 줄이는 효과가 있고 더욱이 교각의 파손을 일으키는 천공을 하지 않으므로 교각 손상을 방지할 수 있는 이점이 있다.The above-described buried anchor structure 100 has the advantage of being able to prevent damage to the pier since it is easy to construct and thus reduces installation cost, and does not perform perforation causing damage to the pier.
