본 고안은 내부에서 작용하는 수압에 효율적으로 견딜 수 있으면서도 내부에서물이 흐르는데 지장이 초래되지 않도록 하여주는 상수도용 내압관에 관한 것이다.The present invention relates to a pressure-resistant pipe for water supply that can effectively withstand the water pressure acting in the inside, but does not cause a problem in the water flowing inside.
상수도관은 내부에 흐르는 물의 압력으로 인하여 내부로부터 커다란 수압이 작용하는 관이다. 따라서 상수도관은 이러한 내부하중에 견디도록 두께가 정하여진다. 종래의 상수도관은 균일한 두께를 가지는 원통형의 철파이프, 합성수지 파이프, 또는 콘크리트 파이프들중에서 하나가 선정되어 사용되어 왔다. 이러한 종래의 상수도관은 균일한 두께로 만들어졌기 때문에 단면 2차모멘트가 작아지므로 그 두께가 두꺼워져야 하였다. 이로 인하여 종래의 상수도관은 전반적으로 재료비가 많이 소요되고 중량이 무겨워져서 취급이 불편하여지는 결함이 있었다.A water supply pipe is a pipe in which a large hydraulic pressure is applied from the inside due to the pressure of water flowing therein. Thus, the water pipes are thicknessed to withstand these internal loads. Conventional water pipes have been selected from one of cylindrical iron pipes, resin pipes, or concrete pipes having a uniform thickness. Since the conventional water pipe is made of uniform thickness, the thickness of the cross section should be increased because the secondary moment is small. Due to this, the conventional water pipe has a defect in that it is inconvenient to handle due to heavy material costs and heavy weights.
본 고안의 목적은 내부에서 작용하는 수압에 효율적으로 견딜 수 있으면서도 내부에서 물이 흐르는데 지장이 초래되지 않도록 하여주는 상수도용 내압관을 제공하는 데에 있다.An object of the present invention is to provide a pressure-resistant pipe for water supply that can effectively withstand the water pressure acting in the interior, but does not interfere with the flow of water in the interior.
이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 고안의 상수도용 내압관은 제1도에 도시되는 바와같이, 웨브(10)와 내측 플랜지(20)가 일체로 형성되는 단위체(1)가 내측플랜지(20)를 내면으로 하여 나선형으로 감겨지면서 내측플랜지(20)들의 단부들이 맞닿아 일체로 접합되어서 내측플랜지(20)들을 내벽면으로 웨브(10)는 나선형 돌출리브로 형성되도록 하는 것에 있어서, 상기 단위체(1)는 금속박판의 보강대판(a)이 합성수지재(b)로 감싸지는 수지코팅 금속판(1a)이 사용되고 그 접합부는 플라스틱 용착되도록 구성됨을 그 기술적 구성상의 특징으로 한다.As shown in FIG. 1, the tap water pressure pipe for water supply according to the present invention has a unit body 1 in which a web 10 and an inner flange 20 are integrally wound while spirally wound with an inner flange 20 as an inner surface. The ends of the inner flanges 20 are integrally joined to each other so that the inner flanges 20 are formed on the inner wall so that the web 10 is formed as a spiral protruding rib, and the unit 1 is a reinforcing plate of a metal sheet (a). The technical composition is characterized in that the resin-coated metal plate (1a) is wrapped in a synthetic resin material (b) and the bonding portion is configured to be plastic welded.
이와같이 구성되는 본 고안은 내벽면은 내측플랜지(20)로서 평탄한 면을 이루기 때문에 그 내부에서 물이 원활하게 흐를 수 있으며, 내벽면의 외부에서 나선형으로 일체로 형성되는 웨브(10)는 단면 2차모멘트가 크기 때문에 내부 수압을 효율적으로 감당하여, 재료비를 절감시켜 주는 작용효과를 가진다.The present invention configured as described above has a flat surface as the inner wall surface of the inner flange 20, so that water can flow smoothly therein, and the web 10, which is integrally formed in a spiral shape on the outside of the inner wall surface, has a secondary cross section. Since the moment is large, the internal water pressure can be effectively handled, thereby reducing the material cost.
특히, 상기 단위체(1)는 제2도 및 제3도에 도시되는 바와같이, 금속박판재의 보강대판(a)이 합성수지재(b)로서 감싸지는 것이 소재로서 사용되어 그 접합부는 플라스틱용접이 되도록 하는 이류는 내부에서 작용하는 수압에 대하여 보다 큰 저항력을 갖도록 하기 위함이다.Particularly, as shown in FIGS. 2 and 3, the unit 1 is used as a material in which a reinforcing base (a) of a metal thin plate is wrapped as a synthetic resin material (b) so that the joining portion is made of plastic welding. This is to make a greater resistance to the hydraulic pressure acting inside.
제2도는 본 고안의 한 실시예를 보여주는 것으로서, 내측플랜지(20)의 일단부에 웨브(10)가 수직하게 일체로 연장되는 단면형상을 가지는 앵글형상의 단위체(1)가 나선형으로 감겨져서 서로 맞닿는 내측플랜지(20)의 단부가 일체로 접합되어 만들어지는 상수도용 내압관을 예시한다.2 is a view illustrating an embodiment of the present invention, in which an angle unit 1 having a cross-sectional shape in which a web 10 is vertically integrally extended to one end of an inner flange 20 is wound in a spiral manner. Illustrates a pressure-resistant pipe for water supply, in which an end portion of the inner flange 20 abutting is integrally joined to each other.
제3도는 본 고안의 다른 실시예를 보여주는 것으로서, 내측플랜지(20)의 중간부에 웨브(10)가 수직하게 일체로 연장되는 단면형상을 가지는 단위체(1)가 나선형으로 감겨져서 서로 맞닿는 내측플랜지(20)의 단부가 일체로 접합되어 만들어지는 상수도용 내압관을 예시한다.3 is a view showing another embodiment of the present invention, an inner flange in which a unit body 1 having a cross-sectional shape in which a web 10 is vertically integrally extended in an intermediate portion of the inner flange 20 is wound in a spiral and abuts each other. Water pressure-resistant pipe made by joining the end of 20 integrally is illustrated.
이상은 본 고안의 대표적인 실시예에 대하여 설명하였으나, 본 고안은 반드시 이들의 실시예의 구조에 한정되는 것이 아니고 본 고안의 구성요건을 구비하고 본 고안의 목적을 달성하는 효과를 기대할 수 있는 범위내에서 당업자간에 변경되어 실시될 수도 있는 것이다.As described above, the exemplary embodiments of the present invention have been described, but the present invention is not necessarily limited to the structures of these embodiments, but within the range that can be expected to have an effect of achieving the object of the present invention and having the configuration requirements of the present invention. It may be practiced by those skilled in the art.
