본 발명은 낙석방지용 와이어로프 및 PVC망의 교차부분 고정구에 관한 것으로, 상세하게는 절토사면부에서 발생되는 낙석을 방지하기 위하여 이용되는 와이어로프 및 PVC망의 교차부분에 앙카볼트로 고정설치된 고정구에 있어서, PVC망을 절토면에 밀착하여 고정된 상태가 되도록 PVC망을 걸 수 있게 좌우측부가 하방향으로 절곡된 하부절곡부와, 와이어로프를 걸어 인장력을 가할 수 있도록 U형 조임구를 어긋난 형태로 체결할 수 있게 중앙의 앵커홀 사이에 돌출된 채 나란히 형성된 체결지지부를 구성하여 PVC망과 아울러 와이어로프 교차지점의 결속을 견고히 함으로써 낙석방지에 대한 지지력을 확보하여 낙석발생을 억제하는 낙석방지용 와이어로프 및 PVC망의 교차부분 고정구에 관한 것이다.
The present invention relates to a cross-section fastener of the rockfall prevention wire rope and PVC mesh, and more particularly in a fixture fixed to the cross section of the wire rope and PVC mesh used to prevent rockfall from cut slopes In order to fasten the PVC net so that the PVC net is fixed by being in close contact with the cut surface, the lower bent part of which the left and right sides are bent downward and the U-type fastener can be fastened in a displaced form so that the wire rope can exert a tension force. Rockfall prevention wire rope and PVC which prevents rockfall by securing support for rockfall prevention by forming fastening support parts formed side by side while being protruded between the anchor holes in the center so as to strengthen the binding of the wire rope crossing point together with the PVC net. It relates to a fastener at the intersection of the net.

일반적으로 산에 도로가 신설될 때는 평탄화 작업에 의해 절취 사면이 생성되는데, 이러한 절취 사면의 돌이나 흙이 도로 위로 떨어지는 낙석이 발생된다.In general, when a road is newly established in a mountain, a cut slope is generated by a planarization operation, and rocks or soil of the cut slope are dropped onto the road.

이러한 낙석을 방지하기 위해 통상적으로 낙석방지망이나 락볼트가 사용되는 바, 상기 낙석방지망은 합성수지나 와이어등을 그물 모양으로 제조하여 사면에 덮어씌우고 그 외측에 와이어를 종, 횡 방향으로 교차시켜 설치함으로써 소규모의 낙석을 방지하며, 상기 락볼트는 다수의 철재볼트를 일정 간격을 유지하면서 사면에 체결시킴으로써 사면의 보강효과를 향상시킨다.In order to prevent such a rockfall, a rockfall prevention net or a rock bolt is usually used. The rockfall prevention net is made of synthetic resin or wire in the shape of a net and covered on a slope, and the wires are installed in the longitudinal and transverse directions by crossing the outside. Preventing a small rockfall, the lock bolt is fastened to the slope by a plurality of steel bolts while maintaining a certain interval to improve the reinforcement effect of the slope.

또한 낙석방지망 및 락볼트에 있어, 상기 낙석방지망은 외측에 설치되는 와이어로프와 함께 사면의 일 측에 설치되는 고정부재에 연결되도록 설치되기 때문에 사면에서 떨어지는 소규모의 낙석방지는 용이하나 사면 자체의 강도를 향상시키지는 못하므로 낙석이 크거나 그 양이 많을 때는 낙석방지망 또한 도로측으로 늘어지는 등, 그 체결력이 낮은 문제점이 있고 락볼트는 사면에 직접 체결되어 사면의 강도, 즉 지지력을 향상시킴으로써 사면이 크게 무너지는 것을 방지할 수 있으나 다수의 락볼트 사이에서 발생되는 소규모의 낙석이 떨어지는 것은 방지할 수 없는 문제점이 있다.In addition, in the rockfall prevention net and rock bolt, the rockfall prevention net is installed so as to be connected to the fixing member installed on one side of the slope with the wire rope installed on the outside, it is easy to prevent the small falls falling off the slope, but the strength of the slope itself If the rockfall is large or the amount is large, the rockfall prevention net also falls to the side of the road, and the fastening force is low. The lock bolt is directly fastened to the slope to improve the strength of the slope. Falling can be prevented but there is a problem that can not prevent falling of the small rockfall generated between a plurality of rock bolts.

또한, 종래기술에 의한 낙석방지망 및 락볼트가 일체로 설치되는 결착식 낙석방지망은 고정장치의 구조가 복잡하고, 구조상의 결함이 있어 시공이 용이하지 못하고, 고정장치를 제조 시에 불량률이 높은 문제점이 있다.In addition, the rockfall prevention net according to the prior art and the rock-type rockfall prevention net is integrally installed, the structure of the fixing device is complicated, there is a structural defect is not easy to install, high defect rate when manufacturing the fixing device There is this.

이러한 상기와 같은 문제점들을 해결하고자 등록실용 20-0387409호에서는, 일측에 삽입홀이 형성되고 꺽임부가 형성된 제1측판과 제2측판이 대향되게 구비되며 중심에 앵커홀이 형성된 고정플레이트와; 일측은 고리부가 형성되고 타측은 나사부가 형성되어 상기 제1측판 및 제2측판의 삽입홀에 삽입되는 한편, 상기 고리부가 와이어로프를 잡아당겨 인장을 가하게 되는 것을 특징으로 하는 낙석방지망용 와이어로프의 교차부분 고정구를 제공함으로써 상기 문제점들을 해결하지만, 고정플레이트에 일체형으로 형성되어 절곡된 제1측판 및 제2측판에서 가장 중용한 낙성방지 역할을 수행하는 와이어로프를 결속한 조임구가 체결되기 때문에 고정플레이트의 제1측판 및 제2측판의 휨력 보다 더 큰 힘이 와이어로프에 발생하게 되면 제1측판 및 제2측판이 휘어짐으로써 와이어로프를 걸 수 없게 되어 와이어로프가 제1측판 및 제2측판에서 탈리되어 절토사면지에서 발생하는 낙석을 방지할 수 없게 되고 제1측판 및 제2측판이 고정플레이트의 양단부에서 비대칭 구조로 절곡되어 있기 때문에 제1측판 및 제2측판의 휨력 보다 큰 힘이 와이어로프에 발생할 때 고정플레이트가 비틀릴 수 있어 낙석 방지를 온전하게 수행할 수 없다.In 20-0387409 for solving the above problems, the fixing plate formed with an anchor hole in the center and provided with an insertion hole is formed on one side and the first side plate and the second side plate formed with a bent portion; One side is formed with a ring portion and the other side is formed with a screw portion is inserted into the insertion hole of the first side plate and the second side plate, while the ring portion of the wire rope for rockfall prevention nets, characterized in that the tension is applied by pulling the wire rope The above problems are solved by providing a cross-section fastener, but the fasteners are fastened by binding wire ropes which are integrally formed on the fixing plate and which perform the most important fall prevention role in the bent first side plate and the second side plate. If a force greater than the bending force of the first side plate and the second side plate of the plate is generated in the wire rope, the first side plate and the second side plate are bent, so that the wire rope cannot be hooked, and the wire rope is removed from the first side plate and the second side plate. It is not possible to prevent falling rocks from the cut slopes, and the first side plate and the second side plate are enlarged at both ends of the fixing plate. Because of the bending structure, the fixing plate may be twisted when a force greater than the bending force of the first side plate and the second side plate occurs in the wire rope, and thus the fall prevention may not be carried out intact.

즉 와이어로프를 걸게 되는 고정플레이트의 제1측판 및 제2측판의 구조가 취약한 문제점을 갖게 됨으로써 낙석 방지용 와이어로프가 낙석을 방지하는 역할을 제대로 수행하지 못한다.That is, the structure of the first side plate and the second side plate of the fixing plate which hangs the wire rope has a weak problem, so that the rockfall prevention wire rope does not properly perform the role of preventing the falling rock.

또한 와이어로프뿐만 아니라 낙석 방지를 보조적으로 수행하는 낙석방지망의 걸림 구조에 대한 설명은 발명의 상세한 설명 및 도면 그 어디에도 찾아볼 수 없기 때문에 상기 고정플레이트의 제1측판 및 제2측판의 휨 발생이 있을 경우에는 낙석을 방지할 수 있는 해결 수단이 보조적으로 마련되지 못하여 낙석을 전혀 방지할 수 없게 된다.
In addition, since the description of the locking structure of the rockfall prevention net that assists the rockfall prevention as well as the wire rope is not found anywhere in the detailed description and the drawings, there may be warpage of the first side plate and the second side plate of the fixing plate. In this case, a solution to prevent rockfall cannot be provided in an auxiliary manner so that rockfall cannot be prevented at all.
