본 발명은 낙석방지망 지지체에 관한 것으로서, 더욱 상세하게는 메인링과 보조링으로 이루어지는 링조립체를 활용하여 낙석방지망의 보조적 지지, 철망 보수, 도로표지 또는 절개면 안전 점검용으로 활용되는 낙석방지망 지지체에 관한 것이다.The present invention relates to a rockfall prevention net support, and more particularly, to a fallfall prevention net support used for auxiliary support of a fallfall prevention net, wire mesh repair, road sign or cutting surface safety inspection by utilizing a ring assembly composed of a main ring and an auxiliary ring. it's about

도로에 인접한 자연 사면이나 인위적 절개면(이하 ‘절개면’이라 한다)에는 강우나 동결융해 등의 원인으로 낙석이 수시로 발생하며, 이를 방치시 낙석이 도로로 유입되어 교통사고를 유발할 수 있다.Falling rocks frequently occur on natural slopes or artificial incisions adjacent to roads (hereinafter referred to as ‘incisions’) due to rainfall or freezing and thawing.

이에 절개면에는 통상적으로 낙석방지시설이 설치되는데, 낙석방지시설로는 주로 암석 절개면에 설치되는 낙석방지망(Rockfall Protection Net)과 토양 절개면에 설치되는 낙석방지망옹벽(Barrier)이 대표적이다.Accordingly, a rockfall prevention facility is usually installed on the incision, and the fallfall prevention facility is mainly a rockfall protection net installed on the rock incision and a rockfall prevention net retaining wall installed on the soil incision.

낙석방지망의 기본구성은 도 1에 도시된 바와 같이 절개면을 덮는 철망(2)과 철망(2)을 격자 형태로 고정 지지하는 와이어로프(3)로 이루어지며, 와이어로프(3)에 의해 지지되는 철망(2)은 낙석을 잡아주거나 절개면과 철망(2) 틈사이 하부 공간으로 떨어지도록 유도하는 역할을 한다.As shown in FIG. 1, the basic configuration of the fall prevention net is composed of a wire mesh 2 covering the cut surface and a wire rope 3 that fixes and supports the wire mesh 2 in a lattice form, and is supported by the wire rope 3 The wire mesh (2) serves to catch the falling rock or induce it to fall into the lower space between the cut surface and the wire mesh (2) gap.

다만, 일부 낙석은 절개면의 외형 특성 등 여러 원인에 의해, 절개면 상부 임의의 지점에 적층되는데(이하 ‘적층부위’라 한다), 적층이 과도해지면 해당 부위의 철망(2)이 찢어져 도로로 낙석이 유입될 수 있는 바, 지속적인 점검과 보수가 요구된다.However, some rockfalls are piled up at an arbitrary point on the top of the cut surface due to various reasons such as the external appearance of the cut surface (hereinafter referred to as 'stacked area'). This bar can flow in, so continuous inspection and maintenance are required.

도 2, 도 3 및 도 4를 참조하면, 본 발명은 메인링(10), 보조링(20) 및 결합구(30)를 기본 구성으로 하되, 상기 메인링(10)에 반사링(40)이나 반사패드(50)가 선택적으로 구비되는 것을 특징으로 한다.2, 3 and 4, the present invention has a main ring 10, an auxiliary ring 20 and a coupler 30 as a basic configuration, but the main ring 10 has a reflective ring 40 or a reflective pad 50 is characterized in that it is selectively provided.

상기 구성 요소들을 중심으로 본 발명의 구체적인 내용을 설명하면, 먼저 메인링(10)과 보조링(20)은 통상 강봉재(鋼棒材)를 굽힘가공(bending)하여 원형으로 제작하되, 상기 보조링(20)은 메인링(10)보다 작은 직경으로 제작한다.Referring to the specific content of the present invention centering on the above components, first, the main ring 10 and the auxiliary ring 20 are produced in a circular shape by bending a normal steel bar, but the auxiliary ring (20) is manufactured with a smaller diameter than the main ring (10).

따라서, 강봉재 자체의 강성과 함께 외력 작용시 원형 형상의 탄성 변형으로 인해 본 발명에 따른 낙석방지망 지지체의 강성이 강화된다.Therefore, the rigidity of the rockfall prevention net support according to the present invention is enhanced due to the elastic deformation of the circular shape when an external force is applied together with the rigidity of the steel bar itself.

상기 메인링(10)과 보조링(20)은 결합구(30)와 같은 체결수단을 통해 상호 연결되어 조립체를 이루며(이하 ‘링조립체’라 한다) 절개면에 직접 고정되거나 와이어로프(3)나 철망(2)에 고정된다.The main ring 10 and the auxiliary ring 20 are interconnected through a fastening means such as a coupler 30 to form an assembly (hereinafter referred to as a 'ring assembly'), and are directly fixed to the cut surface or wire rope 3 It is fixed to the wire mesh (2).

한편, 상기 링조립체는 도 5에 도시된 바와 같이 주로 긴 밴드(band)타입(A)이나 다각형타입으로 조립 제작되는데, 밴드타입(A)의 링조립체는 주로 와이어로프(3)를 보강하는데 사용되며, 다각형타입의 링조립체는 철망(2) 전체를 보강하거나 찢어진 철망(2) 부위를 보수하는데 사용된다.On the other hand, the ring assembly is mainly assembled and manufactured in a long band type (A) or polygonal type, as shown in FIG. 5, and the ring assembly of the band type (A) is mainly used to reinforce the wire rope (3). And, the polygonal type ring assembly is used to reinforce the entire wire mesh (2) or repair the torn wire mesh (2).

또한, 다각형타입의 링조립체는 적층부위의 성장으로 인해 철망(2)이 과도하게 튀어나올 경우, 해당 부위를 덧씌움으로써 철망(2) 파손을 미연에 방지할 수 있다.In addition, when the wire mesh 2 protrudes excessively due to the growth of the laminated portion of the polygonal type ring assembly, damage to the wire mesh 2 can be prevented in advance by covering the corresponding portion.

또한, 상기 링조립체는 밴트타입과 다각형타입이 조합된 형태로 구성될 수도 있다.In addition, the ring assembly may be configured in a combination of a bent type and a polygonal type.

상기 반사링(40)으로는 주로 차량용 반사판이나 안전삼각대로 사용되는 합성수지 또는 알루미늄 반사판이 채용되며, 메인링(10)에 수용홈을 형성하고 여기에 삽입되어 고정되거나 또는, 나사 등의 체결수단을 통해 메인링(10)에 고정되게 된다.As the reflective ring 40, a synthetic resin or aluminum reflector, which is mainly used as a vehicle reflector or a safety tripod, is employed, and an accommodation groove is formed in the main ring 10 and inserted into and fixed thereto, or a fastening means such as a screw is used. It is fixed to the main ring 10 through.

상기 반사패드(50)는 메인링(10)과 대응되는 크기를 갖는 원판형의 패드본체(51), 상기 패드본체(51)의 테두리로부터 돌출 형성되는 복수의 분기패드(52), 패드본체(51)의 전면 중앙에 구비되는 원형의 반사판(53), 및 패드본체(51)와 분기패드(52)의 후면에 구비되는 벨크로세트(54, 54')로 이루어진다.The reflective pad 50 includes a disk-shaped pad body 51 having a size corresponding to that of the main ring 10, a plurality of branch pads 52 protruding from the rim of the pad body 51, and a pad body ( 51) is composed of a circular reflector 53 provided in the center of the front surface, and velcro sets 54 and 54' provided on the rear surfaces of the pad body 51 and the branch pad 52.

상기 반사패드(50)의 메인링(10) 고정은 분기패드(52)가 메인링(10)을 감싼 상태에서 벨크로세트(54, 54')의 상호 접착을 통해 이루어진다.The fixing of the main ring 10 of the reflective pad 50 is achieved through mutual adhesion of Velcro sets 54 and 54' in a state where the branch pad 52 surrounds the main ring 10.

링조립체에 구비되는 복수의 메인링(10) 중 일부를 반사링(40)이나 반사패드(50)가 구비된 메인링(10)으로 배치하면 도 6에 도시된 바와 같이 방향표지나 이정표지 등과 같은 도로표지(B)로 활용될 수 있다. If some of the plurality of main rings 10 provided in the ring assembly are disposed as the main ring 10 provided with the reflective ring 40 or the reflective pad 50, as shown in FIG. 6, direction signs or milestone signs, etc. It can be used as the same road sign (B).

한편, 반사패드(50)가 구비된 메인링(10)을 이용하여 절개면의 안전 점검을 실시할 수 있다.On the other hand, it is possible to perform a safety inspection of the cut surface using the main ring 10 equipped with the reflection pad 50 .

일례로, 반사패드(50)가 구비된 복수의 메인링(10)을 상호 등간격을 이루며 철망(2) 전체에 분산 배치하고 절개면으로부터 떨어진 일정 지점(통상 도로 맞은면)에 기준점을 설정한 상태에서, 해당 기준점에서 절개면에 대한 사진 촬영작업을 소정 기간 간격으로 반복 실시한다.As an example, a plurality of main rings 10 equipped with reflective pads 50 are distributed at equal intervals to each other throughout the wire mesh 2, and a reference point is set at a certain point away from the cut surface (usually the opposite side of the road) In this state, the photographing operation for the cut surface at the corresponding reference point is repeatedly performed at intervals of a predetermined period.

만약, 적층부위의 성장 등과 같은 이유로 일부 반사패드(50)의 반사각이 변하면 사진상의 해당 반사패드(50) 이미지의 명도나 색상이 변하는 바, 사진 대조를 통해 절개면의 위험 징후를 용이하게 파악할 수 있다.If the reflective angle of some of the reflective pads 50 changes for reasons such as the growth of the laminated area, the brightness or color of the corresponding reflective pad 50 image on the photograph changes, so it is possible to easily identify the danger signs of the incision through photo comparison. there is.

이상에서 본 발명의 바람직한 실시예를 설명하였으나, 본 발명의 권리범위는 이에 한정되지 아니하며 본 발명의 실시예와 실질적으로 균등한 범위에 있는 것까지 본 발명의 권리범위가 미치는 것으로 이해되어야 하며, 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시가 가능하다.Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and it should be understood that the scope of the present invention extends to those within the scope substantially equivalent to the embodiments of the present invention. Various modifications and implementations are possible by those skilled in the art to which the invention pertains without departing from the spirit of the invention.
