Abstract

A corrugated protective pipe structure for construction of the present invention has a structure in which a corrugated pipe unit (12) is contracted or relaxed to a required length so as to protect a blind spot at the end of a power line, which is an unprotected section that is left unprotected by the existing protective pipe (1) produced in a standardized 2M or 1M length. Therefore electric shock accidents and electrical breakdowns that occur due to contact with a worker's body or metallic scaffolding can be prevented in advance.

Description

주름형 건축용 방호관 구조체{Structure for Protective Hose of Folding Type}Corrugated protective pipe structure for construction {Structure for Protective Hose of Folding Type}

본 발명은 주름형 건축용 방호관 구조체에 관한 것으로서, 더욱 상세하게는 배전선로 등의 전력선 끝단 일부에 기존 방호관이 설치되지 못하는 사각지대를 방호할 수 있는 주름형 건축용 방호관 구조체에 관한 것이다.The present invention relates to a corrugated protective pipe structure for construction, and more particularly, to a corrugated protective pipe structure for construction capable of protecting a blind spot where existing protective pipes cannot be installed at a portion of the end of a power line such as a distribution line.

일반적으로 가공 배전선로에 인접한 건축물 신축 및 증축 공사현장, 수목접촉 우려 개소, 또는 기타의 장소에서 배전선로의 접촉에 따른 고장정전 및 안전사고를 예방하기 위하여 전력선에 방호관을 설치하여 전력선을 방호하고 있다.In general, in order to prevent power outages and safety accidents due to contact with distribution lines at new construction and extension construction sites of buildings adjacent to overhead distribution lines, areas concerned about tree contact, or other places, protective tubes are installed on power lines to protect power lines. there is.

현행 배전선로 등의 전력선에 설치되는 방호관은 도 1에 도시한 바와 같이 2M 또는 1M의 길이로 정형화되어 있기 때문에 1M 이내 길이가 남게되는 경우, 도 2와 같이 미방호인 상태로 방지하게 된다.Since the protective tubes installed on power lines such as current distribution lines are standardized to a length of 2M or 1M as shown in FIG. 1, if the length within 1M remains, it is prevented in an unprotected state as shown in FIG. 2.

그래서 미방호인 상태를 방치할 경우 건축현장 인근 배전선로 등의 전력선에 작업자의 신체 또는 금속성 비계가 접촉하는 감전사고와 전기 고장이 발생되기 때문에 최소한의 비용으로 방호관의 설치가 가능하도록 공사비를 절감할 수 있는 연장형 전선 방호관의 개발이 절실한 상황이다.Therefore, if the unprotected state is left unprotected, electric shock accidents and electrical breakdowns occur when the body of a worker or metallic scaffolding contacts power lines such as distribution lines near the construction site. There is an urgent need to develop an extension type wire protection pipe that can do this.

Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the examples described in detail below. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same configuration may be indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

본 발명의 실시예에 따른 주름형 건축용 방호관(10)은 배전선로 등의 전력선의 끝단 사각지대를 방호하도록 기존 방호관(1)의 끝단에 연결되어진다. The corrugated protective pipe 10 for construction according to an embodiment of the present invention is connected to the end of the existing protective pipe 1 to protect the blind spot at the end of a power line such as a distribution line.

즉, 상기 방호관(10)은, 길이방향으로 신축되는 주름관부(12)와, 상기 주름관부(12)의 양 끝단에 각각 결합되어 기존 방호관(1)의 끝단에 포개어져 연결되는 한 쌍의 이음자재부(14)로 구성되어 있다. That is, the protective pipe 10 is coupled to both ends of the corrugated pipe part 12 that expands in the longitudinal direction and the corrugated pipe part 12, respectively, and a pair of overlapping and connected ends of the existing protective pipe 1 It is composed of the joint material portion 14 of.

이때, 상기 주름관부(12)는 절연성이 좋은 폴리에틸렌 재질로 이루어진 것으로서, 도 5(a)와 같이 최대 수축시 길이가 1M이고, 도 5(c)와 같이 최대 이완시 길이가 2M로 조절되도록 제작되는 것이 바람직하다. 즉, 상기 방호관(10)은 비주름관부를 포함하고, 상기 비주름관부에 의해 최대 수축시 길이가 1M이고, 상기 주름관부(12) 및 상기 비주름관부에 의해 최대 이완시 길이가 2M으로 조절될 수 있다.At this time, the corrugated pipe part 12 is made of a polyethylene material with good insulation, and is manufactured to have a length of 1M at maximum contraction as shown in FIG. 5 (a) and a length adjusted to 2M at maximum relaxation as shown in FIG. it is desirable to be That is, the protective tube 10 includes a non-corrugated pipe portion, and has a length of 1M when maximally contracted by the non-corrugated pipe portion, and a length controlled to 2M when maximally relaxed by the corrugated pipe portion 12 and the non-corrugated pipe portion. It can be.

상기 한 쌍의 이음자재부(14)는 강화 실리콘 재질로 구성하는 것이 바람직하다. The pair of joint material parts 14 are preferably made of a reinforced silicon material.

상기 주름관부(12)와 한 쌍의 이음자재부(14)의 둘레 일측에는 방호관(10)의 둘레측을 벌려서 기존 방호관(1)의 끝단 또는 배전선로 등의 전력선 둘레에 끼울 수 있도록 길이 방향을 따라 서로 일치되는 절개면(12a)(14a)이 각각 형성되어 있다. On one side of the circumference of the corrugated pipe part 12 and the pair of joint material parts 14, the circumferential side of the protective pipe 10 is widened so that it can be inserted around the end of the existing protective pipe 1 or a power line such as a distribution line in the longitudinal direction Cut surfaces 12a and 14a matching each other along are respectively formed.

이 처럼, 본 발명의 주름형 건축용 방호관(10)은 도 6(a)(b)(c)와 같이 정형화된 2M 또는 1M 길이로 생산된 기존 방호관(1)에 의해 방호되지 못하고 방치된 미방호 구간인 전력선의 끝단 사각지대를 방호할 수 있도록 주름관부(12)가 필요한 길이만큼 수축 또는 이완되는 구조이기 때문에 작업자의 신체 또는 금속성 비계가 접촉되어 발생되었던 감전사고와 전기 고장을 미연에 방지할 수 있는 장점이 있다.As such, the corrugated construction protective pipe 10 of the present invention is not protected by the existing protective pipe 1 produced in a standardized 2M or 1M length as shown in FIG. 6 (a) (b) (c) Since the corrugated pipe part 12 is contracted or relaxed by the required length to protect the blind spot at the end of the power line, which is an unprotected section, electric shock accidents and electrical failures caused by contact with the worker's body or metallic scaffolding are prevented in advance There are advantages to doing so.
