이탈방지 압륜용 피복 강관{A pressure device for prevent separate of pipe}A pressure device for prevent separate of pipe

본 발명은 이탈방지 압륜용 피복 강관에 관한 것으로, 더욱 상세하게는 피복 강관의 좌,우측중 어느 한쪽 단부에 별도의 이음수단을 일체로 형성한 후, 상기한 이음수단을 통하여 피복 강관과 피복 강관이 간편하게 연결 시공되게 함은 물론 부품수를 줄여 생산원가를 절감할 수 있도록 한 이탈방지 압륜용 피복 강관에 관한 것이다.The present invention relates to a coated steel pipe for release prevention pressure ring, and more specifically, after forming a separate joint means integrally at either end of the left and right sides of the coated steel pipe, the coated steel pipe and the coated steel pipe through the above joint means This provides a simple connection construction, as well as a fall-proof pressure coated sheathed steel pipe that can reduce the number of parts to reduce the production cost.

일반적으로 상수도관으로 사용되는 피복 강관은 필요로 하는 길이만큼 절단한 후, 이탈방지 압륜을 이용하여 절단된 피복 강관이 이음관에서 이탈되지 않도록 연결시공 하고 있다. In general, the coated steel pipe used as a water supply pipe is cut to the required length, and then the coated steel pipe cut using the separation prevention pressure ring is connected so as not to be separated from the joint pipe.

상기와 같은 종래 이탈방지 압륜의 전체적인 구성을 간단하게 살펴보면 도1 내지 도4에서와 같이 일정한 길이로 절단된 피복 강관(100)과 피복 강관(110)을 이음하는 이음관(200)과, 상기 이음관(200)의 좌우측에 피복 강관(100)(110)의 단부가 각각 삽입될 때 상기한 이음관(200)의 좌우측에 체결볼트(330)를 통하여 체결 고정되는 압륜(300)과, 상기 이음관(200)의 좌우측에 피복 강관(100)(110)이 각각 삽입되고 피복 강관(100)(110) 외주면에 압륜(300)이 위치한 상태에서 압륜(300)에 형성된 조임볼트(310)를 나사 조임하면 피복 강관(100)(110) 외주면을 밀착하여 피복 강관(100)(110)이 이음관(200)에서 이탈되는 것을 방지할 수 있도록 조임볼트(310)와 연결 형성되는 스파이크(320)로 구성되어 있다. Looking at the overall configuration of the conventional release prevention pressure ring as described above briefly as shown in Figures 1 to 4, the joint pipe 200 and the joint pipe 200, and the joint is cut to a constant length cut steel pipe 110, When the ends of the coated steel pipe (100, 110) is inserted into the left and right sides of the pipe (200), respectively, the pressure ring 300 is fastened and fixed through the fastening bolt 330 to the left and right sides of the joint pipe 200, and the joint The coated steel pipes 100 and 110 are inserted into the left and right sides of the pipe 200, and the tightening bolts 310 formed on the pressure wheels 300 are screwed in the state where the pressure wheels 300 are positioned on the outer circumferential surface of the coated steel pipes 100 and 110. When tightened, the outer surface of the coated steel pipe 100, 110 is in close contact with the spike 320 formed in connection with the tightening bolt 310 to prevent the coated steel pipe 100, 110 from being separated from the joint pipe 200. Consists of.

이와 같이 구성된 종래 피복 강관(100)(110)을 이음관(200)에 이음하고자 할 때에는 먼저 이음관(200)의 좌,우측에 압륜(300)을 각각 위치시킨 다음 압륜(300)이 이음관(200)에서 분리되지 않도록 체결볼트(330)를 이용하여 체결 고정시킨다.When the conventional coated steel pipe 100 and 110 configured as described above are to be joined to the joint pipe 200, first, the pressure wheel 300 is positioned on the left and right sides of the joint pipe 200, and then the pressure wheel 300 is the joint pipe. Fix the fastening using the fastening bolt 330 so as not to be separated from the (200).

이후 피복 강관(100)(110)을 이음관(200)의 좌,우측에 각각 삽입하면 압륜(300)의 중앙에 위치한 스파이크(320)가 피복 강관(100)(110) 외주면에 위치하게 된다. 이때 조임볼트(310)를 나사조임 하면 상기한 조임볼트(310)에 의해 스파이크(320)가 피복 강관(100)(110)의 외주면에 압착 고정되기 때문에 피복 강관(100)(110)은 이음관(200)에서 이탈되지 않고 연결 시공되는 것이다.Then, when the coated steel pipes 100 and 110 are respectively inserted into the left and right sides of the joint pipe 200, the spike 320 positioned at the center of the pressure ring 300 is positioned on the outer circumferential surface of the coated steel pipes 100 and 110. At this time, when the tightening bolt 310 is screwed, since the spike 320 is fixed to the outer circumferential surface of the coated steel pipe 100, 110 by the tightening bolt 310, the coated steel pipe 100, 110 is a joint pipe It is to be connected construction without departure from 200.

이와 같이 종래 이탈방지 압륜을 이용하여 피복 강관(100)과 피복 강관(110)을 연결시공할 수 있다는 이점은 있으나, 종래 피복 강관(100)(110)에는 별도의 이음수단이 마련되어 있지 않고 대부분이 별도의 이음관(200) 및 압륜(300)을 통하여 연결 시공작업이 이루어진다. 따라서 종래에는 피복 강관(100)과 피복 강관(110)을 이음하기 위해서는 별도의 이음관(200)과, 압륜(300) 2개소가 필요하기 때문에 많은 부품수 증가로 인해 이음작업이 불편하고 시간이 많이 소요되는 단점이 있을뿐 아니라, 생산원가가 상승되는 등의 제반 문제점이 있었다. As described above, although there is an advantage in that the coated steel pipe 100 and the coated steel pipe 110 can be connected by using the conventional release preventing pressure ring, the conventional coated steel pipe 100 and 110 are not provided with a separate joint means. Connection construction is made through a separate joint pipe 200 and the pressure wheel 300. Therefore, in order to jointly cover the coated steel pipe 100 and the coated steel pipe 110, since a separate joint pipe 200 and two pressure rings 300 are required, the joint work is inconvenient and time-consuming due to the increase in the number of parts. Not only does it take a lot of disadvantages, but there are various problems such as an increase in production costs.

본 발명은 상기와 같은 종래 제반 문제점을 감안하여 안출한 것으로, 피복 강관의 좌,우측중 어느 한쪽 단부에 별도의 이음수단을 일체로 형성한 후, 상기한 이음수단을 통하여 피복 강관과 피복 강관이 간편하게 연결 시공되게 함은 물론 부품수를 줄여 생산원가를 절감할 수 있도록 한 이탈방지 압륜용 피복 강관을 제공하는 데 있다.The present invention has been made in view of the above-mentioned conventional problems, and after forming a separate joint means integrally at either end of the left and right sides of the coated steel pipe, the coated steel pipe and the coated steel pipe through the above joint means In addition to providing easy connection construction, it is also to provide a steel strip for separation prevention steel pipe that can reduce production costs by reducing the number of parts.

상기와 같은 목적을 달성하기 위한 수단으로 본 발명은 피복 강관의 좌,우측중 한쪽 단부을 선택하고 선택된 단부에 이음수단을 형성하되, 이 이음수단은 피복 강관의 단부가 내부로 삽입될 수 있도록 확장 형성되는 확장부와, 상기 확장부가 확장될 때 완만한 경사를 가지고 피복 강관 몸체와 확장부 사이에 형성되는 경사부와, 상기 확장부 끝단에 형성되고 바깥쪽으로 확장되면서 경사각을 갖는 연결부가 일체로 형성되는 것과, 상기 확장부, 경사부, 연결부의 단면 두께는 피복 강관의 단면 두께와 동일하게 형성하여 균일한 강도를 얻게 하고, 상기 연결부는 25°~ 27°의 경사각을 갖는 것과, 상기 연결부의 경사각과 동일한 경사각을 갖는 경사걸림턱이 내벽에 형성되고 연결부의 외주면에 위치한 상태에서 체결볼트의 걸림턱이 밀착되면 압륜과 함께 피복 강관과 피복 강관을 서로 이음하는 이음소켓으로 구성되는 것을 그 기술적 구성상의 기본 특징으로 한다.The present invention as a means for achieving the above object is to select one end of the left and right sides of the coated steel pipe and form a joint means at the selected end, the joint means is formed so that the end of the coated steel pipe can be inserted into the interior And an inclined portion formed between the coated steel pipe body and the expanded portion having a gentle slope when the expanded portion is expanded, and a connecting portion formed at the end of the extended portion and extending outward and integrally formed with an inclined angle. The cross-sectional thicknesses of the expansion part, the inclination part, and the connection part are formed to be equal to the cross-sectional thickness of the coated steel pipe to obtain uniform strength, and the connection part has an inclination angle of 25 ° to 27 °, and the inclination angle of the connection part. When the locking jaw of the fastening bolt is in close contact with the inclined locking jaw having the same inclination angle formed on the inner wall and located on the outer peripheral surface of the connection part, Consisting of a joint steel pipe and a joint socket for joining the coated steel pipe to each other is a basic feature of the technical construction.

이상에서 살펴본 바와 같이 본 발명에 따르면, 피복 강관의 좌,우측중 어느 한쪽 단부에 확장부, 경사부, 연결부로 이루어진 이음수단이 일체로 형성되어 있고, 이 이음수단은 이음소켓과 함께 피복 강관과 강관을 연결 시공하도록 되어 있다. 따라서, 종래와 같이 피복 강관의 연결 시공작업을 위하여 압륜 2개소, 이음관이 필요없고 압륜 1개소만 필요하기 때문에 부품수가 절감되어 생산원가가 절감될 수 있을 뿐 아니라, 간편하게 피복 강관의 연결 시공작업이 이루어지는 것이다.As described above, according to the present invention, a joint means consisting of an extension part, an inclined part, and a connection part is integrally formed at either end of the left and right sides of the coated steel pipe, and the joint means together with the joint socket and the coated steel pipe.

이하 본 발명의 바람직한 실시예를 첨부 도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명도 이탈방지 압륜을 이용하여 피복 강관(10)과 피복 강관(11)을 이음하는 기본적인 구성은 종래와 같다. 상기 이탈방지 압륜은 외주면에 일정한 간격을 두고 수평 방향으로 다수의 체결볼트(21)가 형성되고 피복 강관(10)의 외주면 단부에 위치하는 압륜(20)과, 상기 체결볼트(21) 사이에 각각 형성되고 피복 강관(10) 외주면 방향으로 나사 조임되는 조임볼트(30)와, 상기 조임볼트(30) 하단에 연결 형성되고 피복 강관(10) 외주면에 밀착 고정되는 스파이크(31)로 구성된다.In the present invention, the basic configuration of joining the coated steel pipe 10 and the coated steel pipe 11 by using the separation prevention pressure ring is the same as in the prior art. The release preventing pressure wheel has a plurality of fastening bolts 21 formed in the horizontal direction at regular intervals on the outer circumferential surface and are located between the pressure wheel 20 positioned at the end of the outer circumferential surface of the coated steel pipe 10 and the fastening bolts 21, respectively. It is formed of a tightening bolt 30 is formed and screwed in the direction of the outer circumferential surface of the coated steel pipe 10, and the spike 31 is connected to the lower end of the tightening bolt 30 and tightly fixed to the outer circumferential surface of the coated steel pipe (10).

본 발명은 더욱 간편하게 피복 강관(10)과 피복 강관(11)이 연결 시공될 수 있도록 한 것으로 이는 도5 내지 도7에서와 같이 피복 강관(11)의 좌,우측중 한쪽 단부을 선택하고 선택된 단부에 일체로 형성되는 이음수단(50)과 별도로 제작되는 이음소켓(40)이 기본적으로 동원된다.According to the present invention, the clad steel pipe 10 and the clad steel pipe 11 can be connected to each other more easily. This is to select one end of the left and right sides of the coated steel pipe 11 as shown in FIGS. The joint socket 50 which is manufactured separately from the joint means 50 formed integrally is basically mobilized.

이음수단(50)은 피복 강관(10)의 단부가 내부로 삽입될 수 있도록 확장 형성되는 확장부(52)와, 상기 확장부(52)가 확장될 때 완만한 경사를 가지고 피복 강관(11) 몸체와 확장부(52) 사이에 형성되는 경사부(53)와, 상기 확장부(52) 끝단에 형성되고 바깥쪽으로 확장되면서 경사각(θ)을 갖는 연결부(51)가 일체로 형성된다. The joint means 50 is an expansion portion 52 which is formed to be extended so that the end of the coated steel pipe 10 can be inserted into the inner portion, and the coated steel pipe 11 has a gentle inclination when the expansion portion 52 is expanded. An inclination portion 53 formed between the body and the expansion portion 52 and a connection portion 51 formed at the end of the expansion portion 52 and extending outwardly and having an inclination angle θ are integrally formed.

상기 확장부(52), 경사부(53), 연결부(51)의 단면 두께(t2)와 피복 강관(11)의 단면 두께(t1)를 동일하게 형성하여 전체적으로 균일한 강도를 얻을 수 있도록 하였으며, 이를 위하여 상기 연결부(51)는 25°~ 27°의 경사각(θ)을 갖도록 형성한다.The cross-sectional thickness t2 of the expanded portion 52, the inclined portion 53, the connecting portion 51 and the cross-sectional thickness t1 of the coated steel pipe 11 were formed to be the same so as to obtain a uniform overall strength. To this end, the connection part 51 is formed to have an inclination angle θ of 25 ° to 27 °.

여기서, 연결부(51)의 경사각(θ)이 25°이하일 경우에는 고무패킹(60)의 크기가 작아지기 때문에 피복 강관(10)과 피복 강관(11)과의 연결부위의 수밀을 효과적으로 유지할 수 없고, 연결부(51)의 경사각(θ)이 27°이상일 경우에는 연결부(51)의 두께가 얇아져 강도가 크게 저하되는 단점이 있다. 따라서, 연결부(51)의 경사각(θ)은 25°~ 27°의 경사각을 갖도록 형성하는 것이 바람직하다. Here, when the inclination angle θ of the connecting portion 51 is 25 ° or less, the size of the rubber packing 60 decreases, so that the watertightness of the connection portion between the coated steel pipe 10 and the coated steel pipe 11 cannot be effectively maintained. In the case where the inclination angle θ of the connecting portion 51 is 27 ° or more, the thickness of the connecting portion 51 becomes thin, and thus the strength is greatly reduced. Therefore, it is preferable that the inclination angle θ of the connecting portion 51 is formed to have an inclination angle of 25 ° to 27 °.

이음소켓(60)은 연결부(51)의 경사각(θ)과 동일한 경사각을 갖는 경사걸림턱(41)이 내벽에 형성되고 연결부(51)의 외주면에 위치한 상태에서 체결볼트(21)의 걸림턱(21)이 밀착되면 압륜(30)과 함께 피복 강관(10)과 피복 강관(11)을 서로 이음하도록 구성된다.The joint socket 60 has a locking jaw of the fastening bolt 21 in a state where the inclined locking jaw 41 having the same inclination angle as the inclination angle θ of the connecting portion 51 is formed on the inner wall and located on the outer circumferential surface of the connecting portion 51. When the 21 is in close contact with the pressure ring 30, the coated steel pipe 10 and the coated steel pipe 11 are configured to be connected to each other.

이와 같이 구성된 본 발명을 사용하기 위해서는 먼저 압륜(20), 이음소켓(40)을 각각 준비하고 이음수단(50)은 피복 강관(11) 단부에 일체로 형성한다. 이후, 피복 강관(10)과 피복 강관(11)을 연결 시공하기 위해서는 먼저 피복 강관(10)의 외주면에는 압륜(20)과 고무패킹(60)을 위치시키고, 다른 피복 강관(11) 즉, 이음수단(50)의 연결부(51) 외주면에는 이음소켓(40)을 각각 위치시킨다.In order to use the present invention configured as described above, first, the pressing wheel 20 and the joint socket 40 are respectively prepared, and the joint means 50 is integrally formed at the end of the coated steel pipe 11. Subsequently, in order to connect the coated steel pipe 10 and the coated steel pipe 11, first, the pressure ring 20 and the rubber packing 60 are placed on the outer circumferential surface of the coated steel pipe 10, and the other coated steel pipe 11, that is, the joint The joint sockets 40 are positioned on the outer circumferential surface of the connecting portion 51 of the means 50, respectively.

상기와 같은 상태에서 피복 강관(10)의 단부를 이음수단(50)인 확장부(52) 내부에 삽입하면 압륜(20)과 이음소켓(40)이 마주하는데, 이때 조임볼트(30)를 나사 조임하여 스파이크(31)가 피복 강관(10)의 외주면에 압착 고정되게 한다. 이후 체결볼트(21)를 나사 조임하면 상기한 체결볼트(21)의 걸림턱(22)에 의해 이음소켓(40)이 압륜(30)측으로 이동하고, 이동하는 과정에서 이음소켓(40)의 경사걸림턱(41)과 연결부(51)가 밀착 결합되면서 피복 강관(10)(11)을 서로 연결 시공하는 것이다. 고무패킹(60)은 피복 강관(10)과 피복 강관(11)의 연결부위가 누수되지 않도록 한다.When the end of the coated steel pipe 10 is inserted into the expansion unit 52, which is the joint means 50 in the above state, the pressure ring 20 and the joint socket 40 face each other, and the tightening bolt 30 is screwed. Tightening so that the spike 31 is fixed to the outer peripheral surface of the coated steel pipe (10). Then, when the fastening bolt 21 is screwed, the joint socket 40 is moved toward the pressure wheel 30 by the locking jaw 22 of the fastening bolt 21, and the slope of the joint socket 40 in the process of moving. The locking jaw 41 and the connecting portion 51 are tightly coupled to each other to connect the construction of the coated steel pipe (10) (11). The rubber packing 60 prevents leakage of the connection portion between the coated steel pipe 10 and the coated steel pipe 11.
