본 발명은 전선용 배관에 관한 것으로, 더욱 상세하게는 각종 건축물에 전선을 배설함에 있어, 그 배선되는 전선을 안정적으로 수용 유도되도록 하여, 설치의 편리성을 부여되도록 함과 동시에 외부 간섭 등과 같은 유해 요인으로 부터 전선을 안정적으로 보호할 수 있도록 한 건축용 방수 전선관에 관한 것이다. The present invention relates to a pipe for electric wire, and more particularly, in disposing the electric wire in various buildings, it is possible to stably receive the electric wire to be wired, to provide convenience of installation, and at the same time harmful to external interference. The present invention relates to a waterproof waterproof conduit for stably protecting wires from factors.

일반적으로 각종 건축물 등의 전기 배선공사는 콘크리트 벽체 등에 전선용 배관의 일부를 매몰시키고, 그 매몰된 전선용 배관(이하, 전선관이라 칭함)의 일측과 타측 단부를 벽체 외부로 필요한 길이만큼 인출시켜, 그 인출된 전선관 내부에 전선을 유입 배설되게 함으로서, 이루어지는 것이다.In general, electrical wiring work in various buildings, etc. buried a part of the electric wire pipe for concrete walls, and draws one side and the other end of the buried electric wire pipe (hereinafter referred to as a conduit) to the outside of the wall as necessary. This is accomplished by causing the electric wire to flow in and out of the drawn conduit.

또한, 이러한 건축용 배선공사에 이용되는 전선관은 주로 자유롭게 절곡이 가능한 플렉시블 전선관을 이용하게 되는 것이며, 이러한 전선관은 전선의 외부 간섭 및 충격으로 부터 전선을 보호하고, 전선으로 부터 발생되는 전자파 및 외부 전기적 장애를 차단하는 기능을 갖게 된다.In addition, the conduit used in such construction wiring is mainly to use a flexible conduit that can be bent freely, such a conduit protects the wire from the external interference and impact of the wire, and electromagnetic waves and external electrical obstacles generated from the wire Will have the function to block.

이에, 건축용 배선공사에 이용되고 있는 종래 플렉시블 전선관의 개략적인 구성을 살펴보면;Thus, looking at the schematic configuration of a conventional flexible conduit used in building wiring work;

이는, 주름관의 신장, 수축 및 휨 변형이 용이하도록 다수개로 분리된 다수개의 주름마디 부재를 필요한 길이만큼 다수개로 엮음 결합 되게 하여 구성한 것임을 알 수 있다.This, it can be seen that the configuration is made by weaving a plurality of pleated knuckle members separated into a plurality of necessary length to facilitate the extension, contraction and bending deformation of the corrugated pipe.

하지만, 전술한 바와 같은 종래의 건축용 플렉시블 전선관은 단순히 주름마디 부재의 연결관계로 이루어진 것으로, 이에 빗물 또는 기타 생활 하수 등에 노출될 경우 그 주름마디 연결 틈새를 통한 누수 현상에 의해 누전 및 감전사고의 원인을 제공되게 하는 상당한 구조상의 문제점을 갖게 되는 것이다.However, the conventional flexible flexible conduit for construction as described above is simply made of the connection of the wrinkled node member, when it is exposed to rainwater or other sewage, such as leakage caused by the leakage through the crevice connection gap cause of short circuit and electric shock There is a significant structural problem that makes it possible to provide.

한편, 또 다르게 전술한 바와 같은 종래 건축용 플렉시블 전선관은 단지 전선을 수용 보호되게 하여, 안정적인 배선 관계를 이루도록 한 것에 불과한 것일 뿐, 그 전선관 자체를 보호하기 위한 수단은 전혀 구비하지 못한 것으로, 이에 외부로 부터 필요에 따른 신장, 수축 및 휨 변형 등이 가해질 경우 쉽게 손상되거나 파손되는 내구성 저하의 문제점을 갖는 것이었으며, 특히 설치에 필요한 길이로 전선관의 절단작업을 행할 경우,그 절단부위가 깔끔하게 처리되지 못하게 됨은 물론 전선관을 형성하는 주름마디 부재가 이탈되는 등, 상당한 사용상의 문제점 또한 상존되게 하는 것이었다. On the other hand, another conventional flexible flexible conduit as described above is just to accommodate and protect the wires, and to achieve a stable wiring relationship, there is no means for protecting the conduit itself, so to the outside If the extension, shrinkage, and bending deformation as needed is applied, there is a problem of deterioration of durability that is easily damaged or broken. Especially, when cutting the conduit to the length required for installation, the cutting part is not neatly processed. Of course, there are also significant problems in use, such as the separation of the corrugated member forming the conduit.

따라서, 본 발명은 종래 건축용 전선관의 제반적인 문제점을 해결하고자 창안된 것으로;Therefore, the present invention has been made to solve the general problems of the conventional building conduit;

An object of the present invention is coated with a protective jacket made of a soft synthetic resin material on the outer surface of the conduit used for the construction of the wire, and the coated protective jacket is again fixed by the elastic insulating band, rain water and other living sewage It is to provide a waterproof waterproof conduit for the construction to exert a waterproof function when the conduit is exposed to the back, and also to solve the source of the short circuit of the wires wired by this waterproof function and the cause of electric shock. .

한편, 본 발명에 또 다른 목적으로는 전선관 외측면으로 형성된 보호외피와 탄성절연밴드에 의한 보강구조로서, 전선관에 필요에 따른 신장, 수축 및 휨 변형 등의 외력이 가해질 경우, 이에 탄력적으로 대응되도록 하여, 전선관이 쉽게 파손되거나 손상되는 것을 방지되도록 하고, 아울러 설치에 필요한 길이로 전선관의 절단작업을 행할 경우에 있어서 또한 그 절단부위가 깔끔하게 마감처리되도록 하여 사용의 효율성을 향상되도록 한 건축용 방수 전선관을 제공함에 있다.On the other hand, another object of the present invention is a reinforcement structure of the protective outer shell and the elastic insulating band formed on the outer surface of the conduit, so that when the external force such as elongation, shrinkage and bending deformation is applied to the conduit as needed, it is elastic In order to prevent the conduit from being easily damaged or damaged, and also to cut the conduit to the length required for installation, the construction waterproof waterproof conduit to improve the efficiency of use by making the cutting part neatly finished. In providing.
