본 발명은 낙석을 방지하기 위하여 주로 도로변(일반도로 및 철길)의 암벽이나 암반의 표면에 철망타입으로 설치되는 와이어로프를 고정시켜 주는 낙석방지용 와이어로프고정구에 관한 것이다.The present invention relates to a wire rope fixing device for preventing rockfall to fix the wire rope installed in the wire mesh type mainly on the surface of the rock wall or rock of the roadside (general road and railroad) to prevent rockfall.

이를 좀 더 상세히 설명하면, 상측고정금구와 하측고정금구의 대향면에는 결속돌부와 결속요부을 대응되게 형성하고, 결속돌부와 결속요부에는 대응되는 요철부를 반복적으로 형성하며, 반복적으로 형성된 요철부의 중심선상에는 와이어로프반원장전홈을 각각 대향되게 형성하여서 된 것으로, 대향되는 결속돌부와 결속요부를 와이어로프의 양측에서 결합시켜 와이어로프가 대향되는 와이어로프반원장전홈에 장전되도록 하고, 결속돌부와 결속요부가 결합되는 상측고정금구와 하측고정금구를 통상의 볼트에 의해 결합시켜 주도록 된 낙석방지용 와이어로프고정구를 제공하려는 것이다.In more detail, on the opposing surfaces of the upper fixing bracket and the lower fixing bracket, a binding protrusion and a binding recess are formed to correspond to each other, and the binding protrusion and the binding recess are repeatedly formed with corresponding recesses and protrusions. The wire rope semi-loading grooves are formed to face each other, and the opposite binding protrusions and binding recesses are coupled on both sides of the wire rope so that the wire ropes are loaded in the opposite wire rope semi-loading recesses, and the binding protrusions and binding recesses are An object of the present invention is to provide a rock-resistant wire rope fixing device to combine the upper fixing bracket and the lower fixing bracket to be coupled by a conventional bolt.

통상적으로 도로변(암벽 또는 암반)의 낙석을 방지하기 위하여 설치되는 방법으로서는, PVC가 코팅된 철조망을 암벽(또는 암반)의 표면에 설치하고 그 상면에 와이어로프를 등 간격으로 유지시키면서 교차되게 설치하거나, 또는 암벽(또는 암반)의 표면에 와이어로프를 등 간격으로 유지시키면서 교차되게 설치하는 방법과, 암벽 또는 암반의 하단에 철책을 설치하는 방법이 알려져 있다.In general, a method of installing to prevent rockfall on a roadside (rock wall or rock) is to install a PVC-coated barbed wire on the surface of the rock wall (or rock) and install the wire ropes on the upper surface thereof while maintaining the same distance between them. Or a method of installing wire ropes on the surface of a rock wall (or rock) at equal intervals, and a method of installing an iron fence at the bottom of the rock wall or rock.

특히, 암벽(또는 암반)의 표면에 등 간격을 설치되는 와이어로프를 지지 억 류시켜 주는 종래의 장치는, 상판결속구와 하판결속구의 대향면에 반원형의 반요홈을 각각 교차되게 형성하고, 상판결속구와 하판결속구의 모서리를 통상의 볼트와 너트에 의해 결합/분리시킬 수 있도록 된 것으로, 상판결속구와 하판결속구의 반원형의 요홈에 상하로 교차되는 와이어로프를 각각 결합하여 볼트와 너트에 의해 일체형으로 결합(고정)시켜서 된 것이다.In particular, the conventional apparatus for supporting and retaining wire ropes spaced at equal intervals on the surface of a rock wall (or rock) has a semicircular semi-concave groove formed on the opposing surface of the upper and lower plate binding spheres, respectively. The edges of the sphere and the lower plate binding sphere can be combined / separated by the usual bolts and nuts.The upper and lower plate binding spheres are connected to the semi-circular grooves of the upper and lower wire ropes, respectively. It was made by (fixed).

그러나, 이는 상판결속구와 하판결속구의 대향면에 형성된 반원형의 요홈에 결합되는 와이어로프는 단면상으로 보아 반(1/2)만 반요홈에 삽입되고 나머지는 노출되는데, 노출되는 와이어로프의 외면이 서로 접촉되므로, 와이어로프를 강력하게 억류시킬 수 없을 뿐만 아니라, 상판결속구와 하판결속구를 견실하게 장착시킬 수 없는 문제가 있고, 교차되는 와이어로프에 의해 상판결속구와 하판결속구의 사이에는 공간이 발생하게 되므로 이들 사이로 돌이 유입된 상태에서 지층에 충격이 가해지게 되면 와이어로프가 반요홈에서 이탈되어 결속력을 상실하게 되는 문제가 있다.However, this means that the wire rope coupled to the semi-circular groove formed on the opposite surface of the upper and lower binding spheres is inserted into the half groove and only the half of the wire rope is exposed and the rest of the exposed wire ropes are exposed. Since it is in contact with the wire rope, the wire rope cannot be detained strongly, and the top and bottom binding spheres cannot be securely mounted, and the space between the top and bottom binding spheres is caused by the intersecting wire ropes. Therefore, when the impact is applied to the stratum while the stones are introduced between them, there is a problem that the wire rope is separated from the recess groove and loses the binding force.

이와 같은 문제를 해소할 수 있도록 하기 위하여 제안된 것으로는, 국내 실용신안등록 제255620호와 실용신안등록 제287784호 및 특허 등록 제415170호가 알려져 있다.Proposed to solve such a problem, domestic utility model registration No. 255620, utility model registration No. 287784 and Patent Registration No. 415170 are known.

실용신안등록 제255620호 (낙석방지용 금속망의 결속구)는, 중판결속구의 양면에 반원홈을 교차되게 각각 형성하고, 중판결속구의 양측에 상/하판결속구를 구비하되, 상/하판결속구의 각 내측 면에는 중판결속구의 양면에 형성된 반원홈과 동일하게 반원홈을 각각 형성하며, 중판결속구의 양면과 상/하판결속구에 교차되게 형성된 각 반원홈에 와이어로프를 교차되게 결합하여 통상의 볼트/너트에 의해 결합시키도록 된 것이다.Utility Model Registration No. 255,620 (Balls for Falling-out Metal Mesh) has semicircular grooves formed on both sides of the middle plate binding spheres, and upper and lower plate binding spheres are provided on both sides of the middle plate binding sphere. Each inner side forms semi-circular grooves in the same way as semi-circular grooves formed on both sides of the middle plate binding sphere, and a wire bolt is intersected to connect the semi-circular grooves formed to intersect both sides of the middle plate binding sphere and the upper and lower plate binding spheres. It is to be joined by a nut.

실용신안등록 제287784호(낙석방지용 와이어의 고정장치)는, 평판의 중앙(수직측판의 중간)에 반원돌부가 형성되고 수직측판의 중앙에 반원홈이 형성된 한 쌍의 상부커버와 하부커버를 교차되게 결합시켜, 상기 동일선상의 반대측 반원돌부와 반원홈을 서로 교차상태로 유지시키고, 상부커버와 하부커버를 통상의 볼트와 너트에 의해 체결시키도록 된 것으로, 대향되어 반원돌부와 반원홈에 와이어로프를 교차되게 장착시킨 상태에서 볼트/너트로 체결시켜주도록 된 것이다.Utility Model Registration No. 287784 (fixing device for rockfall prevention wires) intersects a pair of top and bottom covers with a semicircle formed in the center of the plate (middle of the vertical side plate) and a semicircular groove formed in the center of the vertical side plate. By combining so as to keep the opposite semicircle portion and the semicircle groove on the same line to cross each other, and to fasten the upper cover and the lower cover by a normal bolt and nut, the wires are opposed to the semicircle portion and the semicircle groove Tighten with bolts / nuts while the ropes are mounted alternately.

또한, 특허 등록 제415170호(낙석방지용 와이어로프의 교차부분 고정구)는, 중앙선상에 가이드홈이 교차(+자)형으로 형성된 상부고정구와 하부고정구를 형성하고, 상부고정구와 하부고정구를 대향시켜 교차되는 가이드홈에 와이어로프를 교차되게 장착시킨 상태에서 통상의 볼트/너트에 의해 체결시켜 주도록 된 것이다.In addition, Patent Registration No. 415170 (intersection fastener of the falling-rope wire rope) forms an upper fastener and a lower fastener formed by crossing (+ -shaped) guide grooves on a center line, and opposes the upper and lower fasteners. It is to be fastened by a normal bolt / nut in a state in which the wire rope is mounted to cross the guide groove to cross.

그로나, 이들 종래의 고정구(결속구/고정장치)들은 교차되는 와이어로프의 내/외측에서 결합 고정되어 교차부분을 단순하게 지지해주는 것에 불과하여, 와이어로프에 탄력(장력)을 강화시켜 팽팽하게 유지시킬 수 없고, 암벽(또는 암반)의 표면과의 밀착력이 떨어져 암벽(또는 암반)을 견실하게 지지(구속)해 줄 수 없으며, 암벽(또는 암반)과 와이어로프와의 사이에는 공간이 발생하여 이들 사이로 돌이 유입되면서 와이어로프가 결속력을 상실하게 되는 문제가 있다.However, these conventional fasteners (fasteners / fixing devices) are simply fixed on the inside and the outside of the intersecting wire ropes to simply support the cross sections, thereby enhancing tension (tension) in the wire ropes and making them taut. It cannot be maintained, and the adhesion of the rock wall (or rock) to the surface of the rock wall (or rock) cannot be supported (constrained) steadily, and a space is generated between the rock wall (or rock) and the wire rope. There is a problem that the wire rope loses the binding force as the stone flows between them.

본 발명은 상기와 같은 문제를 해소할 수 있도록 더욱 개선된 낙석방지용 와 이어로프고정구를 제공하려는 것이다.The present invention is to provide a further improved rock rope fixture for preventing rockfall to solve the above problems.
