Abstract

A waterproof electric flexible tube for a building is provided to improve reliability of products by minimizing a damage of a surface layer. A melting zinc galvanizing steel plate(40) has a semi circular shape, and has a winding unit which is wound inwardly. The melting zinc galvanizing steel plate(40) is extended to have a constant gap in a spiral shape, and has an elastic force. A synthetic resin extendable connection unit(30) is wound in a spiral shape inside the gap between the melting zinc galvanizing steel plate(40). A radiation hole is formed on a central part. A central unit is protruded in a semi circular shape inwardly by the elastic force of the melting zinc galvanizing steel plate(40). The synthetic resin extendable connection unit(30) is bent inwardly along a length direction. A vinyl chloride coating layer(20) surrounds an outer circumference of the melting zinc galvanizing steel plate(40), and forms an extendable groove unit on a central part of the melting zinc galvanizing steel plate(40). An inner addition unit is protruded inwardly on a space between the melting zinc galvanizing steel plate(40). A supporting unit is formed to be inserted into the inner addition unit of the vinyl chloride coating layer(20). A ring groove is formed inwardly on an outer front end of the supporting unit.

본 발명의 건축물용 방수 전선관은, 외측으로 만곡되어 나선형상으로 감겨지는 용융아연도금강판(40)과, 용융아연도금강판(40)을 내측에서 연결시키며 나선형으로 감겨지는 합성수지재 신축연결구(30)와, 용융ㅇ연도금강판(40)을 외주연을 감싸는 염화비닐(PVC)코팅층(20)과, 염화비닐코팅층(20) 외주연에서 링베어링(13)을 회동지지하는 링회동구(10)로 구성된다.The waterproof conduit for buildings of the present invention is a synthetic resin material expansion connector 30 wound spirally while connecting the hot-dip galvanized steel sheet 40 and the hot-dip galvanized steel sheet 40 wound in a spiral shape to the outside. And, the hot-dip galvanized steel sheet 40 to the vinyl chloride (PVC) coating layer 20 surrounding the outer circumference, and the ring turning hole (10) for supporting the ring bearing 13 in the outer circumference of the vinyl chloride coating layer 20 It is composed.

상기 용융아연도금강판(40)은 반원형상으로 양단은 내측으로 감겨지는 권취부(41)를 갖고, 나선형으로 일정간격을 유지하며 연장되며, 탄성을 갖는다. The hot-dip galvanized steel sheet 40 has a winding portion 41, both ends of which are wound in a semi-circular shape, extends while maintaining a predetermined interval in a spiral shape, and has elasticity.

상기 합성수지재 신축연결구(30)는 일정간격으로 나선형으로 감겨진 상기 용융아연도금강판(40) 사이 간격의 내측에 나선형으로 감겨져서, 양단이 인접된 권취부(41)에 각각 감겨지고, 중심에는 방열공(31)이 형성되며, 용융아연도금강판(40)의 탄성에 의해 평상시에는 중심부가 내측으로 반원형으로 돌출되고, 길이방향으로 신축시에는 내측으로 만곡되게 형성된다. The synthetic resin stretchable connector 30 is spirally wound inside the gap between the hot-dip galvanized steel sheet 40 wound spirally at a predetermined interval, both ends are respectively wound around the winding portion 41, the center The heat dissipation hole 31 is formed, and usually by the elasticity of the hot-dip galvanized steel sheet 40, the center portion protrudes in a semicircle inward, and is formed to be curved inward when stretched in the longitudinal direction.

상기 염화비닐(PVC)코팅층(20)은 상기 용융아연도금강판(40)의 외주연을 감싸고, 용융아연도금강판(40)의 중심측에는 신축요철부(21)가 내외측에 각각 형성되며, 용융아연도금강판(40) 사이의 공간에는 내측으로 돌출된 내측덧살부(22)가 형성된다. The vinyl chloride (PVC) coating layer 20 wraps around the outer circumference of the hot-dip galvanized steel sheet 40, and stretched and uneven portions 21 are formed on the inner and outer sides of the hot-dip galvanized steel sheet 40, respectively, and melted. In the space between the galvanized steel sheet 40, the inner side portion 22 is formed to protrude inward.

상기 링회동구(10)는 상기 염화비닐코팅층(20)의 내측덧살부(22)에 삽입고정되는 지지부(12)가 형성되고. 지지부(12) 외측선단에는 내측으로 요부형성된 링 홈(11)이 형성되어 링베어링(13)이 안착되어 회동된다. The ring turning tool 10 is formed with a support 12 is inserted into the inner portion 22 of the vinyl chloride coating layer 20 is fixed. A ring groove 11 recessed inwardly is formed at the outer end of the support 12 so that the ring bearing 13 is seated and rotated.

이와 같은 본 발명은, 도 1 및 도 2와 같이, 평상시에는 용융아연도금강판(40) 사이의 간격이 좁게 형성되었다가, 도 3과 같이, 길이방향으로 신축될 때에는 용융아연도금강판(40)을 내측에서 연결하는 합성수지재 신축연결구(30)가 만곡되게 변형되면서 연장되고, 염화비닐코팅층(20) 외주연의 신축요철부(21)도 길이방향으로 펼쳐지게 된다.In the present invention, as shown in Figs. 1 and 2, the interval between the hot-dip galvanized steel sheet 40 is usually formed narrow, as shown in Fig. 3, the hot-dip galvanized steel sheet 40 when stretched in the longitudinal direction Synthetic resin expansion and contraction connector 30 is connected to the inner side is extended while being deformed, the uneven portion 21 of the outer periphery of the vinyl chloride coating layer 20 is also unfolded in the longitudinal direction.

이런 본 발명은 건물 벽체의 보호덕트나 천장에 배설시 굴곡부위에서 자유자재로 변형되면서 신축되면서 직진하게 되는바, 이때 염화비닐코팅층(20)에 고정된 링회동구(10)의 링베어링(13)은 물체와 닿으면서 링홈(11) 내에서 회동되어 본 발명 방수 전선관의 직진성을 원활하게 유도하게 된다.The present invention is straight and stretched while being deformed freely at the bent portion when excreted on the protective duct or ceiling of the building wall, wherein the ring bearing 13 of the ring turning hole (10) fixed to the vinyl chloride coating layer 20 is It rotates in the ring groove 11 while being in contact with the object to smoothly guide the straightness of the waterproof conduit of the present invention.

이로 인해 본 발명의 외주연에는 마찰이나 긁힘에 의한 손상이나 파손이 없게 최소화되어 내부 전선관을 외부충격이나 수분으로부터 확실하게 보호하게 된다. As a result, the outer circumference of the present invention is minimized without damage or damage caused by friction or scratching, thereby reliably protecting the inner conduit from external impact or moisture.

또한, 전선관 내부에서 발생되는 열기는 합성수지재 신축연결구(30)의 방열공(31)에 의해 내부 공기층에 의해 열분산되어 냉각을 유도하게 된다.In addition, the heat generated inside the conduit is heat dissipated by the internal air layer by the heat dissipation hole 31 of the synthetic resin expansion and contraction connector 30 to induce cooling.

이와 같이, 본 발명은 방수성이 우수하고 보호덕트 및 천장에 배설시 링베어링에 의해 주변 물체와의 마찰현상이 거의 없어 용이하게 이룰 수 있고, 표피층의 파손현상이 최소화되어 제품의 시공신뢰성을 형성시킬 수 있는 효과가 있다.As described above, the present invention has excellent waterproofness and can be easily achieved due to the absence of friction with surrounding objects by the ring bearing when it is disposed on the protective duct and the ceiling, and the damage of the skin layer is minimized to form the construction reliability of the product. It can be effective.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
