본 발명은 도로변 암벽으로부터의 낙석 방지를 위하여 설치되는 낙석 방지용 철망을 고정 지지하는 와이어로프 고정구에 관한 것이다.The present invention relates to a wire rope fixture for holding and supporting a rock screen for rockfall prevention to prevent rockfall from the roadside rock wall.

낙석이 우려되는 사면에는 PVC로 코팅된 철망을 덮고 철망을 종과 횡으로 교차하는 다수의 와이어로프로 씌워 고정하는 방법이 널리 이용되고 있으며 와이어로프를 암벽에 견고하게 고정하고 교차되는 와이어로프가 서로 미끄러지는 것을 방지하기 위하여 와이어로프 교차지점에는 고정구가 체결된다.On the slopes where there is concern about falling rocks, a method of covering a PVC-coated wire mesh and covering the wire mesh with a plurality of wire ropes crossing the longitudinal and transverse directions is widely used.The wire rope is firmly fixed to the rock wall and the wire ropes intersecting with each other are widely used. Fixtures are engaged at the wire rope intersections to prevent slipping.

종래 와이어로프 고정구로는 상·하 평판에 와이어 고정홈이 십자형으로 형성되고 고정홈에는 와이어 꼬임방향 파형돌기와 상응하는 홈이 연속으로 형성되거나, 와이어를 견고하게 협지할 수 있는 돌기가 형성된 것을 U볼트로 체결하는 형식의 것이 공지되어 있었고,Conventional wire rope fixtures are formed in the cross-shaped wire fixing grooves on the upper and lower plates, the groove is formed in the grooves corresponding to the corrugated direction of the wire twist direction in succession, or projections that can tightly clamp the wire is formed U bolt It is known that the type of fastening with

또 다른 고정구로는 U볼트의 가운데로 교차하는 와이어를 삽입하고 고정판을 씌워 고정볼트로 체결하는 형식의 것이 공지된 바 있었다.As another fixture, it was known to insert a wire crossing into the center of the U bolt and cover the fixing plate to fasten it with the fixing bolt.

그러나 상기와 같은 구성 중 상·하 평판에 와이어 고정홈이 형성된 고정구는 와이어로프가 교차하는 지점에서 중첩되는 와이어로프로 인하여 조립체의 십자형상의 고정홈에 와이어로프를 밀착시키기가 어렵고 밀착되지 않을 경우 와이어로프가 서로 미끄러질 수 있다는 문제점이 있었고, 또한 U볼트와 고정판을 이용하는 방식의 것은 U볼트로 고정시 와이어로프 고정부가 + 자형으로 정렬되지 않고 뒤틀려 체결되어 미관을 저해한다는 문제점이 있었다.However, in the above configuration, the fasteners having the wire fixing grooves formed on the upper and lower plates are difficult to closely adhere to the wire ropes in the cross-shaped fixing grooves of the assembly due to the overlapping wire ropes at the intersection points of the wire ropes. There was a problem that the rope can slide with each other, and also the method of using the U bolt and the fixing plate has a problem that the wire rope fixing part is twisted and fastened rather than aligned in the shape of U when being fixed by the U bolt, thereby hindering aesthetics.

본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로 교차되는 와이어로프가 교차지점에서 뒤틀림 없이 견고하게 고정될 수 있게 하는 수단을 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a means for allowing wire ropes intersected as having been devised to solve the above-mentioned problems can be firmly fixed without twisting at intersections.

본 발명의 또다른 목적은 고정구의 구성을 단순화하여 와이어로프가 고정구의 체결작업을 용이하게 하는 것이다.Another object of the present invention is to simplify the configuration of the fixture to facilitate the fastening of the wire rope fixture.

상기한 목적을 위한 본 발명 십자형 U볼트를 이용한 낙석방지용 와이어로프 고정구는 와이어로프가 교차되는 지점을 고정하는 고정구로 U볼트를 십자형으로 용접하여 일체화하고 십자형 U볼트 사이로 교차되는 와이어로프가 통과되게 한 후 고정판을 씌워 체결너트로 체결하는 것을 특징으로 한다.The rockfall prevention wire rope fastener using the present invention cross-shaped U bolt for the above purpose is a fixture for fixing the point where the wire rope crosses, integrally welded U-bolt crosswise and let the wire rope crossed between the cross-shaped U bolt passed. After the fixing plate is characterized in that the fastening with a fastening nut.

이하에서 첨부한 도면을 참조하여 본 발명의 바람직한 실시 예를 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명 십자형 U볼트의 (a)는 측단면도 및 평면도, (b)는 다른 실시예이고, 도 3은 본 발명 십자형 U볼트를 이용한 낙석방지용 와이어로프 고정구가 체결된 평면도, 도 4는 본 발명의 십자형 U볼트를 이용한 낙석방지용 와이어로프 고정구의 분해사시도이며, 도 5는 본 발명의 또다른 실시 예이다.2 is a cross-sectional side view and a plan view of the present invention cross U-bolt, (b) is another embodiment, Figure 3 is a plan view of the wire rope fastener for preventing rockfall using the present invention cross U-bolt, Figure 4 is 5 is an exploded perspective view of a rockfall prevention wire rope fastener using the cross-shaped U bolt of the present invention, and FIG. 5 is another embodiment of the present invention.

도 2에 도시된 바와 같이 본 발명 십자형 U볼트(10)를 이용한 낙석방지용 와이어로프 고정구(11)는 두개의 U볼트를 십자형으로 교차시키고 교차부는 용접으로 견고하게 일체화시킨다.As shown in FIG. 2, the rockfall prevention wire rope fixture 11 using the present invention cross U bolt 10 crosses two U bolts in a cross shape, and an intersection is firmly integrated by welding.

U볼트를 용접하지 아니하고 십자형으로 중첩하여 사용할 경우 중첩부가 견고 하게 고정되지 못하여 U볼트와 와이어로프 교차부(12)의 접촉상태가 불안정하여 서로 미끄러지는 형상이 발생할 수 있다.When overlapping in a cross shape without welding the U bolt, the overlapping portion may not be firmly fixed, and thus the contact state of the U bolt and the wire rope cross-section 12 may be unstable, thereby causing a sliding shape to each other.

도 3은 십자형의 U볼트 중 서로 마주보는 한쌍의 U볼트에만 고정판(13)을 사용하여 고정한 것으로 고정판(13)이 체결되지 아니하는 U볼트는 교차되는 와이어로프(14)가 서로 비틀리거나 꼬이지 않토록 하는 기능을 가지며, 도 4는 본 발명의 또다른 실시 예로서 십자형 U볼트(10)를 형성하는 4개의 볼트에 일체화된 고정구(11)를 씌우고 체결너트(15)로 고정한 것으로 십자형 U볼트(10)는 각각 와이어로프(14)가 서로 비틀리거나 꼬임을 방지하면서 체결력을 더욱 높일 수 있다.3 is fixed to the pair of U bolts facing each other by using the fixing plate 13, the U bolt that is not fastened to the fixing plate 13 is not twisted or twisted wire rope 14 cross each other 4 is a cross-shaped U bolt which is fixed with a fastening nut 15 and a fastening nut 15 integrated with four bolts forming the cross-shaped U bolt 10 as another embodiment of the present invention. 10 may further increase the tightening force while preventing the wire ropes 14 from twisting or twisting each other.

십자형 U볼트(10)와 체결되는 고정판(13)에서 와이어로프(14)와 접촉되는 부분에는 와이어로프(14)와의 접촉면적을 넓히고 견고하게 협지될 수 있도록 호형의 고정홈(16)이 와이어로프(14)와 접촉되는 방향으로 형성되어 있으며, 호형의 고정홈(16) 내측에는 와이어로프의 꼬임방향과 상응하는 파형의 돌기나 고정돌기(17)를 형성하여 와이어로프(14)와 고정판(13)이 서로 미끄러지는 것을 방지할 수 있게 구성된다.An arc-shaped fixing groove 16 is formed at a portion of the fixing plate 13 which is fastened to the cross-shaped U bolt 10 to be in contact with the wire rope 14 so as to widen the contact area with the wire rope 14 and firmly sandwich the wire rope 14. The wire rope 14 and the fixing plate 13 are formed in a direction in contact with the wire 14, and a protrusion or fixing protrusion 17 having a waveform corresponding to the twisting direction of the wire rope is formed inside the fixing groove 16 of the arc shape. ) Is prevented from slipping on each other.

또한 고정판(13)의 가운데 부분에는 중공부(18)를 형성하여 와이어로프(14)의 교차로 인하여 발생하는 돌출부분을 수용하게 하는 것이 와이어로프와 고정판의 접촉을 더욱 견고하게 할 수 있다.In addition, to form a hollow portion 18 in the center portion of the fixing plate 13 to accommodate the protruding portion generated due to the intersection of the wire rope 14 may further strengthen the contact between the wire rope and the fixing plate.

파형의 돌기(도면 미도시)가 형성되는 고정판(13)은 주조방식에 의하여 제조하는 것이 제작상 용이하며 고정돌기(17)가 형성되는 고정판(13)은 프레스에 의한 펀칭작업에 의하여 용이하게 삼각형으로 돌출되게 할 수 있다.The fixing plate 13 in which the corrugated protrusion (not shown) is formed is easy to manufacture by a casting method, and the fixing plate 13 in which the fixing protrusion 17 is formed is easily triangulated by punching by press. To protrude.

고정판(13)은 대기중에 장기간 노출되는 점을 고려하여 융용아연도금과 같은 부식방지 처리를 하는 것이 필요하며 U볼트는 흑피 처리하여 내산화성을 증가시킬 수도 있다.The fixed plate 13 needs to be subjected to a corrosion protection treatment such as hot dip galvanizing in consideration of long-term exposure to the air, and the U bolt may be blackened to increase oxidation resistance.

이상에서 설명한 바와 같이 본 발명 십자형 U볼트를 이용한 낙석방지용 와이어로프 고정구는 교차되는 와이어로프가 서로 비틀리거나 꼬이지 아니하여 외관을 보다 미려하게 할 수 있고, 구성이 단순하여 제작이나 체결작업이 용이하여 시공 비용을 경감하게 하는 효과가 있다.As described above, the rockfall prevention wire rope fastener using the cross-shaped U bolt of the present invention can make the appearance more beautiful without twisting or twisting wire ropes to cross each other, and the construction is simple and easy to manufacture or fasten. It has the effect of reducing costs.
