본 발명은 아스팔트 도로에 미리 천공된 드릴구멍에 앵커볼트를 고정하기 위해 사용되는 앵커에 관한 것으로, 보다 상세하게는 합성수지 재질의 삽입앵커의 내부에 금속재 핀으로 구성된 나사산 걸림부재를 수평으로 관통되게 삽입시킴으로써 앵커볼트가 삽입앵커의 내부에 원활히 스크루 삽입될 수 있도록 하고 앵커볼트가 삽입앵커에 삽입될 때 상기 나사산 걸림부재의 양단 끝이 드릴구멍의 내측에 박히게 함으로써 기후변화에 따른 아스팔트 도로의 팽창과 수축에 대응되도록 하여 앵커의 인발력이 향상되도록 하는 아스팔트 도로용 앵커에 관한 것이다.The present invention relates to an anchor used for fixing anchor bolts to drill holes drilled in advance on an asphalt road, and more particularly, to insert a thread-locking member consisting of metal pins horizontally through the inside of an insertion anchor made of a synthetic resin material. This allows the anchor bolt to be smoothly screwed into the insertion anchor, and both ends of the thread locking member are stuck inside the drill hole when the anchor bolt is inserted into the insertion anchor, thereby expanding and contracting the asphalt road due to climate change. The present invention relates to an anchor for an asphalt road to correspond to and to improve the pulling force of the anchor.

일반적으로 앵커는 드릴 등으로 미리 천공된 건물이나 도로의 드릴구멍에 삽입되는 것으로, 상기 앵커의 내측으로 앵커볼트가 체결되면서 드릴구멍의 내부에서 확장되어 이 드릴구멍의 내부로 앵커볼트를 고정하는데 널리 사용되는 것이다.In general, the anchor is inserted into the drill hole of the building or road pre-drilled with a drill or the like, and the anchor bolt is fastened to the inside of the anchor and is expanded in the drill hole to secure the anchor bolt in the drill hole. It is used.

도 6에 도시된 바와 같이, 케미컬 앵커방식은 드릴로 아스팔트에 드릴구멍(H)을 천공한 다음 에폭시와 같은 접착제(S)를 상기 드릴구멍(H)에 주입하고, 상기 드릴구멍(H)에 에폭시와 같은 접착제(S)가 충진된 상태에서 앵커볼트(B)를 상기 드릴구멍(H)에 삽입하여 접착 응고시켜 상기 앵커볼트(B)를 고착시키는 방식이다. As shown in Figure 6, the chemical anchor method drills a drill hole (H) in the asphalt with a drill and then injects an adhesive (S) such as epoxy into the drill hole (H), the drill hole (H) The anchor bolt B is inserted into the drill hole H in a state in which an adhesive S such as epoxy is filled, thereby fixing the anchor bolt B by fixing.

또 다른 방식으로 도 7에 도시된 바와 같이, 타격 앵커방식은 드릴로 아스팔트에 드릴구멍(H)을 천공한 다음 강철재의 앵커(A)를 상기 드릴구멍(H)에 삽입하고, 상기 앵커(A)의 상단에서 내측으로 앵커볼트(B)를 타격하면서 강제로 삽입시켜 상기 앵커(A)의 하단부가 벌어지면서 상기 앵커볼트(B)를 상기 드릴구멍(H)에 고정시키는 방식이다.In another way, as shown in Figure 7, the hitting anchor method drills a drill hole (H) in the asphalt with a drill and then inserts the steel anchor (A) into the drill hole (H), the anchor (A) The anchor bolt (B) is fixed to the drill hole (H) while the lower end of the anchor (A) is opened by forcibly inserting while hitting the anchor bolt (B) inward from the top.

또 다른 방식으로 도 8에 도시된 바와 같이, 칼블럭 앵커방식은 칼블럭이라 불리는 합성수지 재질의 앵커(A)를 드릴로 미리 천공된 아스팔트의 드릴구멍(H)에 삽입하고, 상기 앵커(A)의 상단에서 내측으로 상기 앵커(A)의 내경보다 상대적으로 큰 외경을 갖는 앵커볼트(B)를 체결함으로써, 상기 앵커(A)가 벌어지면서 앵커볼트(B)와 드릴구멍(H)의 사이를 채우게 되고, 그에 따라 상기 앵커볼트(B)를 상기 드릴구멍(H)에 고착시키는 방식이다.In another manner, as shown in FIG. 8, the knife block anchor method inserts an anchor A made of a synthetic resin called a knife block into a drill hole H of a pre-punched asphalt with a drill, and the anchor A By fastening the anchor bolt (B) having an outer diameter relatively larger than the inner diameter of the anchor (A) from the top of the inside, the anchor (A) is opened while the gap between the anchor bolt (B) and the drill hole (H) The anchor bolt (B) is fixed to the drill hole (H) accordingly.

그런데, 상기와 같은 종래 기술에는 다음과 같은 문제점이 있다.However, the above conventional technology has the following problems.

아스팔트 도로는 아스콘으로 형성되는 것으로, 아스콘은 일반 콘크리트보다 상대적으로 강도가 약하고 무른 재질로 형성되어 열에 의한 팽창 및 수축 정도가 심하고, 그에 따라 상기와 같은 종래의 강철재의 앵커는 아스콘의 팽창 및 수축에 적절히 대응하지 못하여 아스콘의 팽창 시에 앵커볼트가 드릴구멍에서 쉽게 빠지는 문제점이 있다.Asphalt roads are formed of ascone, and ascone is made of a relatively weaker and softer material than ordinary concrete, so that the degree of expansion and contraction due to heat is severe. Accordingly, the conventional steel anchor is used for expansion and contraction of ascone. There is a problem that the anchor bolt is easily pulled out of the drill hole when inflating the ascon because it does not respond properly.

또한, 종래의 케미컬 앵커는 에폭시와 같은 접착제를 드릴구멍에 주입할 때 천공 시에 발생한 분진이 에폭시와 혼합되어 아스콘과 에폭시 사이의 접착력이 현저히 저하되고, 그에 따라 앵커볼트와 아스콘 사이의 밀착력이 현저히 저하되는 문 제점이 있다.In addition, in the conventional chemical anchor, when the adhesive such as epoxy is injected into the drill hole, the dust generated during drilling is mixed with the epoxy, thereby significantly reducing the adhesion between the asphalt concrete and the epoxy, and thus the adhesion between the anchor bolt and the asphalt concrete is remarkably reduced. There is a problem that is degraded.

또한, 칼블럭이라 불리는 앵커는 합성수지 재질로 형성되어 칼블럭의 내경보다 상대적으로 큰 외경을 갖는 앵커볼트가 칼블럭의 내경 안에서 나사산을 형성하면서 삽입됨으로써 칼블럭의 외경이 확대되어 앵커를 구멍에 밀착시키는 것이나, 칼블럭의 외경 확대가 한계치를 넘어서면 칼블럭의 내주면에 형성되는 앵커볼트의 나사산이 더 깊어지면서 더 이상 칼블럭의 외경을 확대하지 않음에 따라 앵커의 인발력이 현저히 약화되는 문제점이 있다.In addition, the anchor is called a knife block is formed of a synthetic resin material and the anchor bolt having an outer diameter relatively larger than the inner diameter of the knife block is inserted while forming a screw thread in the inner diameter of the knife block to expand the outer diameter of the knife block to close the anchor to the hole If the outer diameter of the knife block exceeds the limit, the anchor bolts formed on the inner circumferential surface of the knife block become deeper and the pullout force of the anchor is significantly weakened as the outer diameter of the knife block is no longer enlarged. .
