본 발명은 교량, 댐, 터널, 옹벽, 암거, 건축물 등의 구조물을 설치하여 프리스트레스트(prestressed)하기 위하여 천공-홀(穿孔-hole)의 길이 또는 깊이가 수십 또는 수백미터의 작은 구멍에 pc강선, 와이어로프, 보강섬유로프 등을 삽입하여 천공-홀⑦(穿孔-hole)의 적정위치에 여러 수 개의 다단앵커볼트(多段-anchor bolt)를 정착시켜 포스트텐셔닝(posttensioning)을 하기 위한 방법에 관한 것으로서,The present invention is a PC steel wire in a small hole of several tens or hundreds of meters in length or depth of perforation-hole for prestressed by installing structures such as bridges, dams, tunnels, retaining walls, culverts, buildings, etc. Inserting wire rope, reinforcing fiber rope, etc. to fix several post-anchor bolts at the proper position of perforation-hole ⑦ (穿孔 -hole) to posttensioning As for

더욱 상세하게는 천공-홀⑦(穿孔-hole)의 지지력(支持力)이 1개의 앵커볼트로 인발강도(引拔强度)에 미치지 못하면 2개 이상의 다단앵커볼트(多段-anchor bolt)를 1개의 로프(rope)또는 철근(鐵筋) 강봉(鋼棒) 등에 장착하여 인발강도(引拔强度)를 향상하기 위한 다단앵커볼트(多段-anchor bolt)의 구성과 압축공기(壓縮空氣)를 이용하여 로프와 앵커볼트를 천공-홀⑦(穿孔-hole)에 삽입 정착하는 방법에 관한 발명이다.More specifically, if the bearing force of the hole-hole ⑦ does not reach the pullout strength with one anchor bolt, two or more multi-anchor bolts may be used. By using a multi-anchor bolt structure and compressed air to improve the pulling strength by attaching to a rope or reinforcing steel bar, etc. The present invention relates to a method of inserting and fixing a rope and an anchor bolt into a hole-hole ⑦ (穿孔 -hole).

따라서 조적식구조(組積式構造, masonry structure)공법으로 시공한 구조용블록(출원번호10-2002-0080088)의 설비구(設備構)와 암반의 천공-홀⑦(穿孔-hole)에 pc강선, 와이어로프, 보강섬유로프를 삽입하고 다단앵커볼트(多段-anchor bolt)를 정착시켜 프리스트레스트(prestressed)하기 위한 것이다.Therefore, the PC steel wire in the hole of the structural block (Application No. 10-2002-0080088) constructed by the masonry structure method and the hole-hole ⑦ of the rock To prestressed by inserting a wire rope, reinforcing fiber rope and fixing a multi-anchor bolt.

그러므로 본 발명의 다단앵커볼트는 선재를 사용함으로서 길이와 깊이의 제한을 받지 않으며, 직선이 아닌 곡선의 천공-홀⑦(穿孔-hole)에도 로프와 앵커볼트의 삽입과 장착하기 편리하며, 다단앵커볼트를 사용함으로서 지지력(支持力)이 부족한 천공-홀에 여러 수 개의 앵커볼트를 동시에 정착 사용함으로서 높은 인장력과 고지지력(高支持力)이 요구되는 시설물에 매우 적합하다.Therefore, the multi-stage anchor bolt of the present invention is not limited in length and depth by using a wire rod, and it is convenient to insert and mount a rope and anchor bolt in a non-linear curved perforation-hole ⑦ (穿孔 -hole), and the multi-stage anchor By using bolts to anchor several bolts at the same time in the drill-hole that lacks the bearing capacity, it is very suitable for the facilities requiring high tensile strength and high bearing capacity.

공지의 앵커볼트는 강봉(鋼棒) 또는 철근(鐵筋) 등 막대기(bar)용 자재에 사용되도록 고안되어있기 때문에 수 미터 또는 십여 미터의 짧은 직선의 천공 홀에 1개의 앵커볼트만을 정착하도록 되어있어 조적식구조의 설비구에는 사용할 수가 없으며, 또한 천공-홀⑦의 지지력이 부족하면 그라우팅(grouting)후 프리스트레스트(prestressed)를 해야 하는 등 많은 문제점이 대두되고 있다.Known anchor bolts are designed to be used in bar materials such as steel bars or rebars, so that only one anchor bolt is settled in a short straight hole of several meters or tens of meters. There is a lot of problems, such as the use of the masonry structure equipment, and the lack of support of the hole-hole ⑦ has to be prestressed after grouting (pre-stressed).

그르므로 본 발명의 압축공기를 이용한 로프의 삽입방법과 다단앵커볼트의 정착방법은 조적식구조 등의 길고 깊은 설비구 뿐만 아니라 지지력이 비교적 적은 연암 등의 천공-홀⑦에도 삽입과 정착이 뛰어나 여러 구조물에 사용하기 편리하다.Therefore, the method of inserting the rope using the compressed air of the present invention and the method of fixing the multi-stage anchor bolt are not only long and deep equipment such as a masonry structure, but also excellent in insertion and fixation in the hole-hole ⑦ such as soft rock, which has a relatively low bearing capacity. It is convenient to use in the structure.

따라서 로프⑥의 삽입을 원활히 하기 위하여 추진-캡②이 천공-홀⑦에 밀착되어 압축공기가 세어나가지 못하도록 탄성이 좋은 재료를 선택하여야 하며, 다단앵커볼트의 완전한 정착을 위하여 앵커너트④에 부착된 스프링⑤은 복원능력이 뛰어나고 날개가 날카로워 설비구와 암벽에 잘 박히거나 잘 고정될 수 있는 강성이 뛰어나야 한다.Therefore, in order to facilitate the insertion of the rope ⑥, select the material with good elasticity so that the pushing-cap ② closes to the perforation-hole ⑦ and prevents the compressed air from leaking, and it is attached to the anchor nut ④ for the complete fixing of the multi-stage anchor bolt. The spring ⑤ should be excellent in its resilience and its stiffness so that it can be well nailed or fixed to the equipment and rock wall.

그리고 1개의 로프⑥에는 여러 수 개의 다단앵커볼트가 소요되어도 선단의 추진-캡②은 반드시 1개만을 사용하여야 한다.And even if several ropes of multi-stage anchor bolts are required for one rope⑥, only one prop-cap② of the tip should be used.

[발명의 상세한 설명]Detailed description of the invention

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

다단용 앵커볼트란 천공-홀⑦의 지지력(支持力)이 1개의 앵커볼트로 인발강도((引拔强度)에 미치지 못하여도 2개 이상의 앵커볼트를 1개의 로프⑥나 철근 강봉 등에 장착하여 인발강도(引拔强度)를 향상하기 위한 다단앵커볼트의 구성과 압축공기⑨(壓縮空氣)를 이용하여 로프⑥와 다단앵커볼트를 천공-홀⑦에 삽입하여 정착하는 방법에 관한 발명이다.Multi-stage anchor bolts are drawn by attaching two or more anchor bolts to one rope ⑥ or reinforcing steel bar even if the bearing capacity of drilling-hole⑦ is less than one anchor bolt. The present invention relates to a structure of a multi-stage anchor bolt for improving strength and a method of inserting and fixing a rope (6) and a multi-stage anchor bolt into a hole-hole (7) by using compressed air (9).

따라서 본 발명은 교량, 댐, 터널, 옹벽, 암거, 건축물 등의 구조물을 프리스트레스트(prestressed)하기 위한 천공(穿孔)의 길이 또는 깊이가 수십 또는 수백 미터의 홀(hole)속에 pc강선, 와이어로프, 보강섬유로프 등을 삽입하여 천공-홀⑦의 필요한 적정부위에 여러 수 개의 다단앵커볼트(多段-anchor bolt)를 정착시켜 포스트텐셔닝(posttensioning)을 하기 위한 것으로 암반의 천공-홀⑦과 조적식구조(組積式構造, masonry structure)공법으로 시공한 구조용블록(출원번호10-2002-0080088)의 설비구(設備構)에 pc강선, 와이어로프, 보강섬유로프를 삽입하고 다단용 앵커볼트를 정착시켜 프리스트레스트(prestressed)하기 위한 것이다.Therefore, the present invention is a PC steel wire, wire rope in a hole of tens or hundreds of meters in length or depth of perforation for prestressing structures such as bridges, dams, tunnels, retaining walls, culverts, buildings, etc. To post-tensioning by inserting reinforcing fiber ropes and fixing several multi-anchor bolts in the proper area of perforation-hole⑦. Multi-stage anchor bolts are inserted by inserting pc steel wire, wire rope and reinforcing fiber rope into the equipment holes of structural block (Application No. 10-2002-0080088) constructed by the masonry structure method. It is to settle and prestressed.

그러므로 본 발명의 다단앵커볼트는 선재로 된 로프⑥를 사용함으로서 길이와 깊이의 제한을 받지 않으며, 직선이 아닌 곡선의 천공-홀⑦에도 로프⑥삽입과 다단앵커볼트의 장착하기 편리하며, 다단앵커볼트를 사용함으로서 지지력(支持力)이 부족한 천공-홀⑦에 여러 수 개의 다단앵커볼트를 설치 사용함으로서 높은 지지력(支持力)이 요구되는 시설물에 매우 적합하다.Therefore, the multi-stage anchor bolt of the present invention is not limited to the length and depth by using the rope ⑥ made of wire rod, it is convenient to insert the rope ⑥ and the multi-stage anchor bolts in a non-linear curved hole-hole ⑦, multi-stage anchor By using bolts, several multi-stage anchor bolts are installed in the hole-hole ⑦ which lacks the bearing capacity, so it is very suitable for the facilities requiring high bearing capacity.

로프⑥와 다단앵커볼트를 천공-홀⑦(穿孔- hole)에 삽입한 순서를 도 1, 도 2, 도 3, 도 4에 따라 설명하면 다음과 같다.The order of inserting the rope ⑥ and the multi-stage anchor bolt into the hole-hole ⑦ (穿孔 -hole) will be described with reference to FIGS. 1, 2, 3, and 4 as follows.

삽입하고자 하는 로프⑥[(rope)의 선단에 그립①(grip)설치하여 추진-캡②이 압축공기에 의해 이탈되지 않도록 고정하고 정착(定着)쐐기③ 로프⑥에 끼우고 스프링⑤ 날개가 부착된 앵커너트④를 그립①을 사용하여 전진과 후진이 도지 않도록 고정하여 천공-홀⑦의 입구에 밀어 넣고 압축공기주입구⑧(壓縮空氣 注入口)를 설치하고 압축공기⑨(壓縮空氣)를 주입하여 일정량의 로프⑤가 삽입되면 설치한 압축공기주입구⑧는 해체하여 또 다른 다단앵커볼트를 같은 방법으로 설치하는 것을 반복하여 로프와 앵커볼트를 삽입한다.Install the grip① (grip) at the tip of the rope⑥ [(rope) to be inserted and fix it so that the prop-cap② is not separated by compressed air, insert it into the fixing wedge③ rope⑥, and have the spring⑤ attached Fix the anchor nut④ by using the grip① to prevent the forward and backward turning, and push it into the inlet of the hole-hole⑦, install the compressed air inlet ⑧ and inject the compressed air ⑨ (壓縮 空 壓縮) When the rope⑤ is inserted, the installed compressed air inlet ⑧ is dismantled and repeats to install another multistage anchor bolt in the same way and insert the rope and anchor bolt.

삽입이 완료된 로프⑤는 인장기계를 사용하여 텐션⑩(tension)하게 되면 로프⑥가 뒤로 밀리면서 다단앵커볼트의 앵커너트④에 부착된 모든 스프링⑤의 날개가 천공-홀⑦의 벽에 의해 1차 가고정(暇固定)되어 앵커너트④를 고정하게 되고 이어서 정착쐐기③가 앙카너트④의 두부에 삽입되면서 앙카너트④를 팽창시켜 천공-홀⑦의 벽에 최종적으로 정착시켜 주게 되는 것이다.When the rope ⑤ has been inserted into the rope ⑤ by tensioning, the rope ⑥ is pushed back and the wings of all the springs ⑤ attached to the anchor nut ④ of the multi-stage anchor bolt are firstly cut by the wall of the hole-hole⑦. It is temporarily fixed and fixed to the anchor nut ④. Then, the fixing wedge ③ is inserted into the head of the anchor nut ④ to inflate the anchor nut ④ and finally fix it to the wall of the hole-hole ⑦.

따라서 다단앵커볼트 삽입할 때 앵커너트④에 부착된 스프링⑤의 날개가 천공-홀⑦이 커지면 많이 펴지고 천공-홀⑦의 크기가 적어지면 오므라져 앵커너트④ 가까이 에 위치하게 된다.Therefore, when inserting the multi-stage anchor bolts, the wings of the spring⑤ attached to the anchor nut④ widen as the drilling-hole ⑦ grows large, and when the size of the drilling-hole ⑦ decreases, they are retracted and positioned near the anchor nut④.

그러므로 앵커너트④에 부착된 스프링⑤의 날개는 항상 천공-홀⑦의 벽에 붙어 있게는 것이다.Therefore, the wings of the spring⑤ attached to the anchor nut④ are always attached to the wall of the hole-hole⑦.

그러므로 본 발명은 교량, 댐, 터널, 옹벽, 암거, 건축물 등의 구조물을 프리스트레스트(prestressed)하기 위한 천공(穿孔)의 길이 또는 깊이가 수십 또는 수백 미터의 홀(hole)속에 pc강선, 와이어로프, 보강섬유로프 등을 삽입하여 천공-홀⑦의 필요한 적정부위에 여러 수 개의 다단앵커볼트(多段-anchor bolt)를 정착시켜 포스트텐셔닝(posttensioning)을 하기 위한 것으로 암반의 천공-홀⑦과 조적식구조(組積式構造, masonry structure)공법으로 시공한 구조용블록(출원번호10-2002-0080088)의 설비구(設備構)에 pc강선, 와이어로프, 보강섬유로프를 삽입하고 다단용 앵커볼트를 정착시켜 프리스트레스트(prestressed)하기 위한 것이다.Therefore, the present invention is a PC steel wire, wire rope in a hole of tens or hundreds of meters in length or depth of perforation for prestressing structures such as bridges, dams, tunnels, retaining walls, culverts, buildings, etc. To post-tensioning by inserting reinforcing fiber ropes and fixing several multi-anchor bolts in the proper area of perforation-hole⑦.

Rope ⑥ and multi-stage anchor bolts are inserted into perforated-hole ⑦ and fixed by using multi-stage anchor bolts to improve strength and compressed air.

따라서 본 발명은 교량, 댐, 터널, 옹벽, 암거, 건축물 등의 구조물을 프리스트레스트(prestressed)하기 위한 천공(穿孔)의 길이 또는 깊이가 수십 또는 수백 미터의 홀(hole)속에 pc강선, 와이어로프, 보강섬유로프 등을 삽입하여 천공-홀⑦의 필요한 적정부위에 여러 수 개의 다단앵커볼트(多段-anchor bolt)를 정착시켜 포스트텐셔닝(posttensioning)을 하기 위한 것으로 암반의 천공-홀⑦과 조적식구조(組積式構造, masonry structure)공법으로 시공한 구조용블록(출원번호10-2002-00800888)의 설비구(設備構)에 pc강선, 와이어로프, 보강섬유로프를 삽입하고 다단용 앵커볼트를 정착시켜 프리스트레스트(prestressed)하기 위한 것이다.Therefore, the present invention is a PC steel wire, wire rope in a hole of tens or hundreds of meters in length or depth of perforation for prestressing structures such as bridges, dams, tunnels, retaining walls, culverts, buildings, etc. To post-tensioning by inserting reinforcing fiber ropes and fixing several multi-anchor bolts in the proper area of perforation-hole⑦.
