낙석방지책의 와이어로프 마모방지구{Piece for preventing wire rope from wearing in a fence for guarding against falling rocks}Piece of Preventing Wire Rope from Wearing in a fence for guarding against falling rocks}

본 발명은 낙석방지책의 지주대에 수평으로 설치되는 와이어로프의 마모를 방지하기 위한 마모방지구에 관한 것으로, 더욱 상세하게는 산간절개지역에 인접한 도로 및 주택지역의 외측에 설치되는 낙석방지책의 지주대에 와이어로프를 고정시키는 고리부가 형성된 고정볼트와 와이어로프간의 접촉면적을 넓게 하므로써, 점접촉에 의한 집중적인 마모로 인하여 발생하는 와이어로프의 손상을 방지하고 와이어로프를 더욱 견고하게 지지하여, 붕괴사고에 의한 낙석 또는 토사유출을 더욱 더 안전하고 효과적으로 방지할 수 있도록 하는 낙석방지책의 와이어로프 마모방지구에 관한 것이다.The present invention relates to a wear protection device for preventing the wear of the wire rope horizontally installed on the strut of the rockfall prevention measures, more specifically, the support of rockfall prevention measures installed on the outside of the road and the housing area adjacent to the mountain cutting area By widening the contact area between the fixed bolt and the wire rope where the loop part is fixed to the base and the wire rope, it prevents damage of the wire rope caused by intensive wear by point contact and supports the wire rope more firmly. The present invention relates to a wire rope wear protection device of a rockfall prevention measure that can prevent a rockfall or earth leakage caused by an accident more safely and effectively.

일반적으로 산간지대의 절개지 혹은 경사면에 인접한 도로 및 주택지역의 외측에 설치되는 낙석방지책(1)은 폭우 및 폭설과 동절기에 얼었던 부분이 녹으면서 생기는 균열에 의한 붕괴사고시 흔히 발생하는 낙석 및 토사유출을 방지하기 위하여 사용된다.In general, rockfall prevention measures (1) installed outside cuts and slopes in mountainous areas or on slopes are often used for falling rocks and soil spills caused by heavy rain, heavy snowfall, and cracks caused by melting of frozen parts in winter. It is used to prevent.

상기와 같이 사용되는 낙석방지책(1)의 구성을 도 1을 참조하여 설명하면, 일정한 거리를 두고 수직으로 설치되어 콘크리트기초공사에 의해 견고하게 고정되며 일정간격으로 볼트삽입공이 형성된 H형상의 지주대(2)와, 지주대(2)사이에 가로로 배치되며 고리부(5a)가 형성된 고정볼트(5)에 의해 지주대(2)에 고정되는 와이어로프(3)와, 지주대(2)사이에 설치되어 상기 와이어로프(3)에 고정되는 PVC코팅처리된 휀스(4)로 구성되어 있다.Referring to the configuration of the rockfall prevention measure (1) used as described above with reference to Figure 1, it is installed vertically at a predetermined distance and firmly fixed by the concrete foundation work, H-shaped struts formed with bolt insertion holes at regular intervals (2) and the wire rope (3), which is horizontally disposed between the support stand (2) and fixed to the support stand (2) by a fixing bolt (5) having a ring portion (5a) formed therein, and the support stand (2). It is composed of a PVC-coated fence (4) installed between and fixed to the wire rope (3).

이와 같이 구성되는 낙석방지책(1)에 있어서 상기 휀스(4)의 강도를 보강하하기 위하여 설치되는 와이어로프(3)의 처짐현상을 방지하고 와이어로프(3)에 적당한 인장력을 가할 수 있도록 하기 위해서, 종래에는 도 2a에 도시된 바와 같이 고리부(5a)가 형성된 고정볼트(5)를 이용하여 와이어로프(3)를 고정볼트(5)의 구부러진 고리부(5a)에 걸어 지주대(2)에 밀착시킨다음 고정볼트(5)를 지주대(2)의 볼트삽입공에 삽입하여 너트(6)로 체결하여 고정되어 있다.In order to prevent sagging of the wire rope 3 installed in order to reinforce the strength of the fence 4 in the rockfall prevention measure 1 configured as described above, and to apply an appropriate tensile force to the wire rope 3. In the related art, as shown in FIG. 2A, the wire rope 3 is hooked to the bent ring portion 5a of the fixing bolt 5 using the fixing bolt 5 having the ring portion 5a formed therein. The fixing bolt 5 is inserted into the bolt insertion hole of the support base 2 and fastened with a nut 6 to fix it.

그러나, 상기와 같이 와이어로프(3)를 고정시킬 경우는 도 2b에 보이는 바와 같이 와이어로프(3)와 고정볼트(5)의 접촉면은 거의 점접촉으로 되어, 와이어로프 (3)에 인장력을 주기 위해 단단하게 고정볼트(5)를 체결할 경우 잦은 낙석 또는 토사유출에 의하여 와이어로프(3)와 고정볼트(5)의 접촉면에서의 집중적인 마모가 생기므로써, 와이어로프(3)를 구성하는 가는 경강선으로 된 소선을 쉽게 손상시키게 되고 따라서 와이어로프(3)의 인장강도가 약화되므로 작은 충격에도 쉽게 절단되어 낙석방지책(1)의 내구성과 안전성에 치명적인 문제점이 되었다.However, in the case where the wire rope 3 is fixed as described above, as shown in FIG. 2B, the contact surface between the wire rope 3 and the fixing bolt 5 is almost in point contact, thereby providing a tensile force to the wire rope 3. In order to fasten the fixing bolts 5 firmly, frequent rockfall or earth leakage causes intensive wear at the contact surface between the wire ropes 3 and the fixing bolts 5, thereby making the wire rope 3 thin. Since the wires made of hard steel wires are easily damaged, and thus the tensile strength of the wire rope 3 is weakened, the wire ropes 3 are easily cut even with a small impact, which is a critical problem for the durability and safety of the rockfall prevention measure 1.

본 발명은 상기 문제점을 해결하기 위하여 낙석방지책의 지주대에 와이어로프를 고정시키는 고리부가 형성된 고정볼트와 와이어로프간의 접촉면을 넓게 하기 위하여 고정볼트와 와이어로프사이에 마모방지구를 삽입하므로써, 잦은 낙석 또는 토사유출에 따른 반복적인 충격하중에 의한 와이어로프의 손상을 방지하고 더욱 더 견고하게 와이어로프를 지지하는 것을 기술적 과제로 한다.In order to solve the above problems, by inserting the wear protection between the fixing bolt and the wire rope to widen the contact surface between the fixing bolt and the wire rope formed with a ring portion for fixing the wire rope to the support of the rockfall prevention measures, frequent rockfall Or it is a technical problem to prevent the damage of the wire rope due to the repeated impact load caused by the soil leakage and to support the wire rope more firmly.

상기 기술적 과제를 달성하기 위하여 본 발명은 낙석방지책의 지주대에 수평으로 설치되는 와이어로프와 지주대에 와이어로프를 걸어 고정시키는 고리부가 형성된 고정볼트사이에 설치되어 와이어로프의 마모를 방지하는 마모방지구에 있어서, 상기 마모방지구는 와이어로프를 감싸도록 반원형상으로 구부러진 굴곡부와, 굴곡부의 일측에서 바깥쪽으로 구부러져 형성되고 고정볼트가 삽입되는 장공이 형성된 플레이트로 이루어진 것을 특징으로 한다.In order to achieve the above technical problem, the present invention is installed between a wire rope installed horizontally on a support stand of a rockfall prevention measure and a fixing bolt having a hook portion formed by hanging a wire rope on a support stand to prevent wear of the wire rope. In the earth, the wear protection is characterized in that the bent portion is bent in a semi-circular shape so as to surround the wire rope, bent outward from one side of the bent portion is formed of a plate formed with a long hole is inserted into the fixing bolt.
