본 발명은 건축용 고신축형 방수 전선관에 관한 것으로서, 보다 상세하게는 배선에 사용되는 전선을 보호하기 위해 전선묶음의 최외층에 하중 또는 부식에 강한 고신축성 특수연질PVC 주름보호관을 형성하고, 그 내측에 고신축성 특수연질PVC 주름보호관과 체결고정되는 나선형의 특수염화비닐수지관을 형성시키며, 그 내측에 특수염화비닐수지관에 나사결합되는 금속재질의 경량신축가요관을 플렉시블하게 구성하여 내수성을 향상시키고, 어느 일측으로 구부려도 내부에 마찰이 발생되지 않으며, 내부의 열을 방출시켜 과열을 방지함으로써 전력손실을 최소화하는 건축용 고신축형 방수 전선관에 관한 것이다.The present invention relates to a high-strength waterproof conduit for construction, and more particularly, in order to protect the electric wire used for wiring to form a highly flexible special soft PVC corrugated protective tube resistant to load or corrosion in the outermost layer of the wire bundle, It forms a spiral special vinyl chloride resin tube that is fastened and fastened with a highly flexible special soft PVC pleated protective tube on the inside, and a metal lightweight lightweight flexible tube that is screwed to the special vinyl chloride resin tube is flexible inside to improve water resistance. And it is related to the high-stretch waterproof waterproof conduit for building to minimize the loss of power by preventing the internal friction is not generated even if bent to any one side, by releasing the heat inside.

일반적으로 건축물의 배선은 건축시공시 전선이 위치하는 부분에 미리 강관 또는 플라스틱관을 설치하고, 상기 강관 또는 플라스틱관의 내부에는 전선을 삽통시킨 후 콘크리트를 타설하여 이루어지고 있다. 또한, 상기 설치방법에 있어 배선이 직각으로 꺾이는 부분은 이음관을 이용하여 서로 다른 2개의 직선형 관을 내통시키게 된다.In general, the wiring of the building is made by installing a steel pipe or a plastic pipe in advance in the place where the electric wire is located during construction, and the concrete is poured after the wire is inserted into the inside of the steel pipe or plastic pipe. In addition, in the installation method, the portion where the wiring is bent at right angles allows two different straight pipes to pass through each other using a joint pipe.

즉, 이와같은 종래의 배선 시공과정은 콘크리트를 타설하기 위한 거푸집 내에 강관 또는 플라스틱관을 이음관으로 각각 연결하는 관연결단계와, 상기 관체의 내부에 전선을 삽입하여 외부로부터 전류가 유입되는 부분과 건축물의 내부에서 전류를 사용하는 부분을 연결하는 전선연결단계와, 상기 연결된 관이 파손되지 않도 록 콘크리트를 타설하는 타설단계로 이루어진다.That is, the conventional wiring construction process is a pipe connection step of connecting the steel pipe or plastic pipe to the joint pipe, respectively, in the formwork for placing concrete, and the part into which the current flows from the outside by inserting a wire into the inside of the pipe; It consists of a wire connection step of connecting the portion using the current in the interior of the building, and placing the concrete so that the connected pipe is not damaged.

그러나, 상기 종래의 시공과정에서는 관연결단계에서 직각으로 꺾이는 부분마다 이음관을 사용해야하는 번거로움이 있다. 또한, 전선연결단계에서의 전선연결은 별도의 인력이 동원되어야 하는 인건비상승요인이 있으며, 타설단계에서는 상기 관을 플라스틱으로 사용할 경우 콘크리트의 하중에 의해 관이 파손될 수 있는 문제점이 있으며, 관을 강관으로 사용할 경우 콘크리트의 수분으로 인해 부식이 발생할 수 있는 문제점이 있는 등 종래의 배선방법은 건축물의 시공시간과 시공비를 증대시키고, 관의 파손 및 부식이 발생되어 원활한 전류의 전달이 이루어질 수 없는 문제점이 내재되어 있다.However, in the conventional construction process, there is a need to use a joint pipe for each portion that is bent at a right angle in the pipe connection step. In addition, there is a labor cost increase factor that requires a separate manpower to be mobilized in the wire connection step, and in the pouring step, when the pipe is used as plastic, the pipe may be damaged by the load of concrete. When used as a conventional wiring method, there is a problem that corrosion may occur due to the moisture of concrete, which increases the construction time and construction cost of the building, and causes problems such as pipe breakage and corrosion, which does not allow smooth current transmission. It is inherent.

따라서, 근래에는 전선을 구성하는 외피를 알루미늄재질의 플렉시블관을 이용하여 별도의 관설치없이 전선 자체를 직접 건물벽체 내부에 삽설하는 방법이 제시되고 있다. 상기 방법은 알루미늄재질의 외피가 콘크리트의 하중을 견디어 내부에 설치된 전선이 눌리거나 단락되는 것을 방지하도록 한 것이다.Therefore, in recent years, a method of directly inserting the wires directly into a building wall without using a separate pipe by using a flexible tube made of aluminum material has been proposed. The method is such that the outer shell of the aluminum material to withstand the load of the concrete to prevent the wires installed therein from being pressed or shorted.

그러나, 상기 플렉시블관의 외피 자체가 일정한 신축이 가능하게 형성되기 때문에 건물내부매입설치시 콘크리트 수분이 플렉시블관의 내부로 유입되어 플렉시블관을 따라 유동됨으로, 플렉시블관의 단부를 통해 전선의 이음부분에 전달되어 누전등에 의한 화재위험 또는 손실전력이 증대되는 문제점이 있었다.However, since the outer shell of the flexible pipe itself is formed to be able to expand and contract uniformly, the concrete moisture flows into the flexible pipe and flows along the flexible pipe when the building is installed inside the building. There was a problem that the risk of fire or loss of power due to short circuit is increased.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 배선에 사용되는 전선을 보호하기 위해 전선묶음의 최외층에 하중 또는 부식에 강한 고신축성 특수 연질PVC 주름보호관을 형성하고, 그 내측에 고신축성 특수연질PVC 주름보호관과 체결고정되는 나선형의 특수염화비닐수지관을 형성시키며, 그 내측에 특수염화비닐수지관에 나사결합되는 금속재질의 경량신축가요관을 플렉시블하게 구성하여 내수성을 향상시키고, 어느 일측으로 구부려도 내부에 마찰이 발생되지 않으며, 내부의 열을 방출시켜 과열을 방지함으로써 전력손실을 최소화하는 건축용 고신축형 방수 전선관을 제공함에 그 목적이 있다.The present invention is to solve the above problems, in order to protect the electric wire used in the wiring to form a high-strength special soft PVC corrugated protective tube resistant to load or corrosion in the outermost layer of the wire bundle, the high elastic special It forms a spiral special vinyl chloride resin tube that is fastened to the flexible PVC pleated protective tube, and a flexible, lightweight flexible flexible tube made of a metal screwed to the special vinyl chloride resin tube is formed inside thereof to improve water resistance.
