It is a schematic diagram.

도 1 내지 도 3에 도시된 바와 같이, 종래 수도관 연결용 클램프는 내충격성 을 갖는 합성수지관으로 이루어진 제1,2관(100)(110)의 연결부위에 대한 이탈을 방지하고자 하는 구조물로서, 이는 적절한 두께의 철판을 이용하여 상,하부에 대응되게 반원형으로 이루어지고, 지지대(210)로써 연결된 제1압륜부(200)와; 제1압륜부(200)와 대응되게 지지대(220)로써 연결된 제2압륜부(230)와; 제1,2압륜부(200)(230)를 체결하기 위한 체결부재(300)로 이루어진다.As shown in Figures 1 to 3, the conventional water pipe connection clamp is a structure to prevent the separation of the connection portion of the first and second pipes 100, 110 made of a synthetic resin pipe having an impact resistance, which is A first pressing portion 200 formed in a semicircle corresponding to the upper and lower portions by using an iron plate having an appropriate thickness, and connected by a support 210; A second pressing unit 230 connected to the first pressing unit 200 by a support 220; It consists of a fastening member 300 for fastening the first and second pressure-wheel parts (200, 230).

이때, 제1,2관(100)(110)은 동일한 직경으로 이루어지고, 제1,2관(100)(110)을 상호 연결하기 위해서는 제1,2관(100)(110)중 어느 하나 관의 일측 영역에 열을 가하여 확관부(120)를 형성한 다음, 이에 확관 하지 않은 평관의 삽입한 후, 이 연결부위를 클램프의 체결력으로써 지지하게 되는 것이다.At this time, the first and second pipes 100 and 110 are made of the same diameter, in order to interconnect the first and second pipes 100 and 110, any one of the first and second pipes 100 and 110. Heat is applied to one region of the tube to form the expansion pipe 120, and then insert the flat pipe not expanded to this, and then to support the connection portion by the clamping force of the clamp.

상기한 확관부(120)는 제1,2,3확관부(a)(b)(c)로 이루어지고, 제1,2확관부(a)(b)와 제2,3확관부(b)(c)의 경계부위에는 제1,2단턱(a-1)(b-1)이 형성되며, 제1,3확관부(a)(c)의 내주연에는 평관의 외주연이 삽입되고, 제2확관부(b)는 평관에 대하여 공간부가 마련되도록 외향으로 돌출되게 형성된다.The expansion unit 120 is composed of first, second and third expansion units (a) (b) and (c), and the first and second expansion units (a) and (b) and second and third expansion units (b). First and second step (a-1) (b-1) is formed at the boundary of the (c), the outer periphery of the flat tube is inserted into the inner circumference of the first, third expansion (a) (c) , The second expansion pipe (b) is formed to protrude outward so that the space is provided with respect to the flat pipe.

이러한 확관부(120)의 제1확관부(a) 외주연에는 제1,2압륜부(200)(220)의 상부 내주연이 삽입되고, 제3확관부(c) 하단부가 접하는 제1관(100) 외주에는 제1,2압륜부(200)(220)의 내주연이 삽입된다. The upper inner circumference of the first and second pressure-reducing parts 200 and 220 is inserted into the outer circumference of the first expansion part (a) of the expansion part 120, and the first pipe contacting the lower end of the third expansion part (c). An inner circumferential edge of the first and second pressure bearing parts 200 and 220 is inserted into the outer circumference 100.

이때, 제1,2압륜부(200)(220)의 하단은 제1,2확관부(a)(b)의 제1단턱(a-1)에 걸리게 되고, 제1,2압륜부(200)(220)의 상단은 제3단턱부(c)의 하단에 걸리게 되어 확관부(120)를 지지하게 된다.At this time, the lower end of the first and second pressure bearing parts 200 and 220 is caught by the first step a-1 of the first and second expansion parts a and b, and the first and second pressure parts 200 The upper end of the (220) is caught by the lower end of the third step (c) to support the expansion unit 120.

한편, 제2관(110)의 확관부(120)가 삽입되는 제1,2압륜부(200)(230)의 상부 내주연은, 제1관(100)의 외주연이 삽입되는 제1,2압륜부(200)(230)의 하부 내주연에 비하여 그 내경이 크게 형성된다.On the other hand, the upper inner circumference of the first and second pressure-reducing parts 200 and 230 into which the expansion pipe 120 of the second pipe 110 is inserted may include the first and second circumferences of the first pipe 100. Compared to the lower inner circumference of the two-wheeled parts 200 and 230, the inner diameter thereof is large.

이때, 제1,2압륜부(200)(230) 하부 내주연에는 체결성을 강화시키기 위하여 다수개의 협지턱(201)이 형성되고, 제1,2압륜부(200)(230) 상부 내주연에 확관부(120)의 제1확관부(a)가 밀착되어 협지턱을 형성할 필요가 없거나, 몇 개의 협지턱(3∼5개정도)만 있으면 된다.At this time, a plurality of clamping jaw 201 is formed on the inner circumferential edge of the first and second pressure bearing parts 200 and 230 and the upper inner circumference of the first and second pressure bearing parts 200 and 230 is formed. The first expansion part a of the expansion pipe part 120 is in close contact with each other, so that it is not necessary to form the holding jaw, or only a few holding jaws (about 3 to 5 pieces) are required.

상기 체결부재(300)는 제1,2압륜부(200)(230)와 지지대(210)(220)에 대응되게 형성된 구멍을 통하여 체결되는 볼트(310) 및 너트(320)로 이루어져 클램프를 구성하는 제1,2압륜부(200)(230)로써 연결부위를 지지하게 되는 것이다.The fastening member 300 is composed of a bolt 310 and a nut 320 fastened through holes formed to correspond to the first and second pressure bearing parts 200 and 230 and the support members 210 and 220 to constitute a clamp. The first and second pressure-bearing parts 200 and 230 are to support the connection portion.

그러나, 이와 같은 종래 수도관 연결용 클램프는 수도관의 제1,2관을 연결한 다음, 이 연결부위에 클램프로써 체결한 후, 이를 지하에 매몰하면, 클램프와 토압에 의하여 내부의 수압을 충분히 견딜 수 있으나, 클램프로써 연결된 제1,2관의 연결부위가 외부로 노출되면 제1,2관의 연결부위에 수돗물의 압력이 직접 가해지게 되는데, However, such a conventional water pipe connection clamp is connected to the first and second pipes of the water pipe, and then fastened to the connection portion as a clamp, and then buried in the basement, can sufficiently withstand the internal water pressure by the clamp and earth pressure. However, when the connection part of the first and second pipes connected by the clamp is exposed to the outside, the pressure of the tap water is directly applied to the connection part of the first and second pipes.

이 경우에 클램프의 제1,2압륜부를 지지대와 체결부재의 체결력으로써 지지하게 되어 수돗물의 수압을 견디지 못하고, 클램프에 변형이 가해져 제2관의 확관부로부터 제1관의 평관이 이탈되어 수돗물의 공급이 용이하지 못하게 되는 문제점이 발생 되었다.In this case, the first and second pressure bearings of the clamp are supported by the clamping force of the support and the fastening member, so that the pressure of the tap water cannot be tolerated, and the clamp is deformed so that the flat pipe of the first pipe is detached from the expansion pipe of the second pipe, The problem is that the supply is not easy.

또한, 확관부의 형성으로 강도가 약해진 부위에 대한 강도를 클램프의 클램핑력으로써 충분히 보강하지 못하는 문제점이 발생 되었다.In addition, there is a problem that the strength of the weakened portion due to the expansion of the expansion portion is not sufficiently reinforced by the clamping force of the clamp.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 발명은 수도관의 연결부위 형성된 확관부 구조에 적절하게 클램프를 구성하여 수돗물의 압력에 의해 수도관의 연결부위가 이탈되는 것을 방지하도록 구성한 수도관 연결용 클램프를 제공하는 데 그 목적이 있다.The present invention has been made in order to solve such a conventional problem, the present invention is configured to properly clamp the expansion pipe structure formed in the connection portion of the water pipe to prevent the connection portion of the water pipe is separated by the pressure of the tap water. The purpose is to provide a clamp for water pipe connection.

본 발명의 과제 해결 수단은 확관부가 형성된 제2관과; 제2관의 확관부 내부에 연결되는 제1관을 클램핑하기 위한 클램프에 있어서, 반원형의 제1,2압륜부로 이루어지고, 내주연에 상기 확관부의 외주연에 밀착되는 밀착지지부가 연장 형성된 제1압륜과; 상기 제1,2압륜부와 대응되게 형성되고, 반원형의 제3,4압륜부로 이루어지고, 제1관의 외주연에 삽입되는 제1압륜과; 상기 제1,3압륜부 및 상기 제2,4압륜부 사이에 일체로 형성되어 제1,2압륜을 지지하기 위한 지지편과; 상기 제1,2,3,4압륜부의 연결부위를 지지하기 위한 체결부재로 구성된 것을 특징으로 하는 한다.The problem solving means of the present invention includes a second pipe formed with an expansion pipe; A clamp for clamping a first pipe connected to an inside of an expansion pipe of a second pipe, the clamp comprising: a semicircular first and second pressure wheels, and having an intimate support portion that is in close contact with an outer circumference of the expansion pipe. 1 wheel; A first pressure ring formed corresponding to the first and second pressure wheel parts, the third pressure wheel part having a semicircular shape, and inserted into an outer circumference of the first pipe; A support piece integrally formed between the first and third pressure wheel parts and the second and fourth pressure wheel parts to support the first and second pressure wheels; Characterized in that it consists of a fastening member for supporting the connecting portion of the first, second, third, fourth pressure wheel.

본 발명의 수도관 연결용 클램프에 따르면, 합성수지관으로 이루어진 제1,2관을 연결하기 위하여 형성된 확관부에 가해지는 고압의 수압을 충분히 견딜 수 있도록 클램프를 구성하여 강도가 약해진 확관부를 구성하는 제1,2확관부 사이의 제1단턱부에 대한 강도를 보강시키게 되었으며, 또한 지지편과 지지대로써 2중으로 클 램프 자체의 강도를 보강시켜 제1,2관의 연결부위를 안정되게 고정시킴에 따라 클램프 자체 변형이 방지되고, 제1,2관의 이탈이 방지되어 원활한 물공급을 할 수 있는 효과가 제공된다. According to the clamp for connecting the water pipe of the present invention, the clamp constituting the clamp to sufficiently endure the high pressure of the water pressure applied to the expansion pipe formed to connect the first and second pipes made of synthetic resin pipe to configure the expansion pipe weakened in strength The strength of the first step between the 1st and 2nd expansion parts is reinforced, and as the support piece and the support bar are doubled, the strength of the clamp itself is strengthened, thereby stably fixing the connection part of the 1st and 2nd pipes. The clamp itself is prevented from deformation and the separation of the first and second tubes is prevented, thereby providing an effect of smooth water supply.

또한, 클램프가 지지편으로 상호 연결되어 있어 제1,2관의 연결부위에 대한 시공이 간편하여 편의성이 제공되는 것이다. In addition, since the clamps are interconnected with the support pieces, the construction of the connecting portions of the first and second pipes is simple, thereby providing convenience.

이하, 첨부된 도면을 참조로 본 발명의 실시를 위한 구체적인 내용을 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described a specific content for the practice of the present invention.

Figure 9 is a block diagram showing an expansion portion coupled to the manual connection clamp according to the present invention.

도 3 내지 도 9에 도시된 바와 같이, 본 발명에 따른 수도관 연결용 클램프는 내충격성을 갖는 합성수지관으로 이루어진 제1,2관(10)(11)의 연결부위에 대한 이탈을 방지하고자 하는 구조물이다.As shown in Figures 3 to 9, the clamp for connecting the water pipes according to the present invention is a structure to prevent the separation of the connection portion of the first and second pipes (10) (11) made of a synthetic resin pipe having an impact resistance to be.

상기한 클램프는 적절한 두께의 철판을 이용하여 대응되게 원형으로 이루어지고, 지지편(40)으로써 상호 연결된 제1,2압륜(20)(30)과; 제1,2압륜(20)(30)에 체결되어 제1,2관(10)(11)의 연결부위를 지지하기 위한 체결부재(50)로 이루어진 다.The clamp is made of a correspondingly circular using an iron plate of a suitable thickness, and the first and second pressure wheels (20, 30) interconnected by a support piece (40); The fastening member 50 is fastened to the first and second pressure wheels 20 and 30 to support the connection portion of the first and second pipes 10 and 11.

이때, 합성수지관으로 이루어진 제1,2관(10)(11)은 용도에 따라 다소 차이가 있으나, 동일한 직경으로 이루어지고, 제1,2관(10)(11)을 상호 연결하기 위해서는 제1,2관(10)(11)중 어느 하나 관의 일측 영역에 열을 가하여 확관부(14)를 형성한 다음, 이에 확관을 하지 않은 다른 평관을 삽입한 후, 이 연결부위를 클램프의 체결력으로써 지지하게 되는 것이다.At this time, the first and second pipes (10, 11) made of a synthetic resin pipe is slightly different depending on the use, but made of the same diameter, in order to interconnect the first, second pipes (10) (11) After heat is applied to an area of one of the two pipes 10 and 11 to form an expansion pipe 14, another flat pipe which is not expanded is inserted into the pipe, and then the connection portion is used as a clamping force of the clamp. Will be supported.

이러한 확관부(14)는 제1,2,3확관부(a)(b)(c)로 이루어지고, 제1,2확관부(a)(b)와 제2,3확관부(b)(c)의 경계부위에는 제1,2단턱(a-1)(b-1)이 형성되며, 제1,3확관부(a)(c)의 내주연에는 평관의 외주연이 삽입되고, 제2확관부(b)는 평관에 대하여 공간부가 마련되도록 외향으로 돌출되게 형성된다.The expansion unit 14 is composed of first, second and third expansion units (a) (b) (c), and the first and second expansion units (a) (b) and the second and third expansion units (b). First and second step (a-1) (b-1) is formed at the boundary of (c), the outer periphery of the flat tube is inserted into the inner circumference of the first, third expansion (a) (c), The second expansion portion (b) is formed to protrude outward so that the space portion is provided with respect to the flat pipe.

이와 같이 확관부(14)가 형성된 관은 상대적으로 그 강도가 약하게 되는데, 약해진 강도를 보강하기 위하여 상기한 클램프를 사용하게 되는 것이다.Thus, the pipe in which the expansion pipe portion 14 is formed is relatively weak in strength, and the above-mentioned clamp is used to reinforce the weakened strength.

이러한 상기한 클램프의 제1압륜(20)은 반원형을 유지하여 대응되게 형성된 제1,2압륜부(22)(24)와; 제2압륜(30)은 반원형을 유지하여 대응되게 형성된 제3,4압륜부(32)(34)로 이루어지고, 제1압륜부(22)와 제3압륜부(32) 및 제2압륜부(24)와 제4압륜부(34)는 중앙역을 지지편(40)으로 상호 연결하여 강도를 보강시키게 된다.The first pressure wheel 20 of the clamp may include first and second pressure wheel parts 22 and 24 formed correspondingly by maintaining a semicircular shape; The second pressing wheel 30 is composed of third and fourth pressing parts 32 and 34 formed correspondingly by maintaining a semicircular shape, and the first pressing part 22, the third pressing part 32, and the second pressing part. The 24 and the fourth pressure bearing portion 34 reinforce the strength by interconnecting the central station to the support piece 40.

상기 제1,2압륜부(22)(24) 내주연에는 제2관(11)에 형성된 확관부(14)를 구성하는 제1확관부(a)의 중앙 영역과 제2확관부(b)가 삽입되어 지지되고, 제3,4압륜부(32)(34) 내주연에는 제1관(10)의 외주연, 즉 평관이 삽입되어 연결부위를 지지하게 된다. 이때, 제1,2압륜부(22)(24)의 상단은 제1확관부(a)의 중앙 영역에 위치 되고, 하단은 제2,3확관부(b)(c)의 경계부위에 형성된 제2단턱(b-1)에 위치되어 제1,2확관부(a)(b)를 지지하게 된다.At the inner circumference of the first and second pressure bearing parts 22 and 24, the central region and the second expanding part b of the first expanding part a constituting the expanding part 14 formed in the second pipe 11. Is inserted and supported, the outer periphery of the first tube 10, that is, the flat tube is inserted into the inner circumference of the third and fourth pressure-reducing parts 32 and 34 to support the connection portion. At this time, the upper end of the first and second pressure bearing parts 22 and 24 is located in the center region of the first expanding part a, and the lower end is formed at the boundary of the second and third expanding parts b and c. It is positioned on the second step b-1 to support the first and second expansion parts a and b.

한편, 제1,2압륜부(22)(24) 내주연에는 제1확관부(a)의 중앙 영역과 제2확관부(b) 외주면이 밀착되도록 밀착지지부(26)가 연장 형성된다. On the other hand, at the inner circumference of the first and second pressure bearing parts 22 and 24, the close support part 26 is formed to be in close contact with the central region of the first expanding part a and the outer peripheral surface of the second expanding part b.

즉, 제2관(11)의 제1,2확관부(a)(b)의 외주면의 형상과 대응되게 밀착지지부(26)가 연장 형성되어 제1,2확관부(a)(b)와 밀착력을 향상시키고, 자체 강도가 약해진 확관부(14)에 대한 강도를 보강시키게 된다That is, the close support part 26 is extended to correspond to the shape of the outer circumferential surface of the first and second expansion parts (a) and (b) of the second pipe (11), so that the first and second expansion parts (a) and (b) It improves adhesion and reinforces the strength of the expansion portion 14 whose strength is weakened.

이때, 지지편(40)은 그 내측면에 확관부(14)의 제3확관부(c) 외주면과 밀착되도록 밀착면(40a)이 형성되어 확관부(14)의 제3확관부(c)의 강도를 보강시키게 된다. 즉, 상기 밀착지지부(26)에 연결되는 지지편(40)의 내측면에는 제3확관부(c) 외측으로 돌출된 외주면에 밀착되게 밀착면(40a)을 형성하게 된다.At this time, the support piece 40 has a close contact surface 40a formed on the inner side thereof so as to be in close contact with the outer circumferential surface of the third expansion unit c of the expansion unit 14, and thus the third expansion unit c of the expansion unit 14 is formed. The strength of the will be reinforced.
