열수축관의 접착구조{connect structure of plastics pipe}Connect structure of plastics pipe

본 고안은 수지관의 연결부분에 열수축관을 수밀성있게 연결할 수 있는 수지관 연결용 열수축관의 연결주조에 관한 것으로, 더욱 상세하게는 수지관들(P.E 하수관, P.E 우수관, P.E오수관, 통신관, 파형관, 파형강관 등)의 연결부분의 양쪽 끝단을 맞대어 열수축관이 열수축되어 접착되도록 함에 있어서의 열수축관의 양쪽끝단이 겹쳐져 열융착되는 부분에 부가하여 등간격으로 리벳트가 리벳팅되어 결속력이 증대토록하여, 열수축관이 수지관의 연결부분에 열수축 성형된 후, 수지관내에 외부의 온도와 큰 차이가 있는 온, 냉의 유통물 또는 화공약품 등이 유통되더라고 열수축관의 열융착부분이 이완되는 일이 없이 유지할 수 있는 동시에, 열융착부분의 리벳트가 열융착부분의 결속력을 증대시키어 수밀 강도를 높임으로서, 결국 열수축관의 인장강도와 파열강도를 높여, 수지관의 연결부위가 누수되는 것을 방지하여 반영구적인 수명을 가질 수 있는 열수축관의 접착구조에 관한 것이다.The present invention relates to a connection casting of a heat shrink tube for connecting a resin tube that can be tightly connected to the heat shrink tube to the connection portion of the resin tube, more specifically, resin pipes (PE sewer pipe, PE storm pipe, PE sewage pipe, communication tube, corrugated pipe , Both ends of the heat-shrink tube to be heat-shrinked and bonded to each other by joining the ends of the corrugated steel pipe, etc.), and the rivets are riveted at equal intervals to increase the binding force. After the heat shrink tube is heat-shrink-molded at the connection portion of the resin tube, the hot-sealed portion of the heat-shrink tube is relaxed even though a hot or cold distribution or a chemical is distributed in the resin tube, which has a large difference from the outside temperature. At the same time, the riveting of the heat-sealed portion increases the binding force of the heat-sealed portion, thereby increasing the watertight strength, and thus, the tensile strength of the heat shrinkable tube The present invention relates to an adhesive structure of a heat shrinkable tube that can increase the bursting strength and prevent leakage of the connection portion of the resin tube and have a semi-permanent life.

본 출원인은 앞서 국내 실용신안등록출원 제 20-2004-0006830호를 제안합 바 있다. 상기 제안에서는 수지관들의 연결부분의 양쪽 끝단을 맞대어 열수축관이 열수축되어 접착되도록 함에 있어서의 상기 열수축관의 바깥쪽 단차 이음부에 접착시트가 접착되는 시임부에 결속부재가 결속고정되도록 하며, 결속부재로서는 리벳트가 시임부에 가로질러 등간격으로 리벳팅할 수 있고, 또한 상기 결속부재로 하여스테이플이 시임부에 가로질러 등간격으로 스테이핑되도록 할 수 있도록 하고 있다.The applicant has previously proposed the domestic utility model registration application No. 20-2004-0006830. In the proposal, the binding member is fastened to the seam to which the adhesive sheet is bonded to the outer step joint of the heat shrink tube in the heat shrink tube to be bonded to both ends of the connection portions of the resin tubes. As the member, the rivet can be riveted at equal intervals across the seam, and the binding member can be used to allow staples to be stapled at equal intervals across the seam.

상기 열수축관의 양쪽 끝단을 겹치게 유지하고, 이 겹쳐진 단차 이음부에 접착시트가 접착되도록 하여, 상기 접착시트가 고정된 단차 이음부에 열융착성형을 행한 후, 상기 열융착성형이 행하여진 시임부에 결속부재를 리벳팅 또는 스테이핑처리하여 수밀성과 결속성을 높일 수 있는데, 상기 열수축관의 소재가 가교화사의 면사, 폴리에스터 또는 그라스사가 경,위사로 직조된 직조물을 가교화 PE 또는 전자조사용PE로 이루어진 수지성형물이기 때문에 별도의 접착부재를 사용하지 않으면서도 열이 가하여지면 가교화사의 수축력과 더불어 열수축관을 수지관의 연결부분을 접착할 수 있다.The seam is formed by holding the both ends of the heat-shrink tube overlapping, and allowing the adhesive sheet to adhere to the overlapped step joint, and performing heat fusion molding on the step joint to which the adhesive sheet is fixed. In order to increase the watertightness and binding property by riveting or stapling the binding member, the material of the heat-shrinkable tube is a cross-linked PE or electron-weaving woven fabric of cotton yarn, polyester or glass yarn of cross-linked yarn. Since it is a resin molding made of PE, when heat is applied without using a separate adhesive member, the heat shrink tube together with the shrinkage force of the crosslinked yarn can be bonded to the connection portion of the resin tube.

따라서, 상기 열수축관의 양쪽 끝단을 겹치게 유지하고, 이어서 겹쳐진 단차 이음부에 접착시트를 별도로 접착하지 않고, 상기 열수축관의 양쪽 끝단을 겹치게 유지한 후, 바로 겹쳐진 부분에 열융착을 행하고 열융착부분에 리벳팅을 행하여도 단차 이음부의 결속력과 수밀강도를 높일 수 있다는 결과를 얻게 되었다. 수밀의 정도를 높이기 위하여 앞서 설명한 바와 같이 열수축관의 양쪽 끝 겹쳐지는 단차 이음부위에 접착시트를 올려놓고 열융착을 행한 후 이어서 열융착부분에 결속부재를 결속하여야 하나, 다소 정도가 요구되지 않는 수지관에서는 고가의 가교화사의 접착시트를 생략하고 보호부재 등으로 대체하여 원가를 낮출 수 있는 대체효과가 기대된다.Therefore, both ends of the heat-shrink tube are overlapped, and then the adhesive sheets are not separately adhered to the overlapped step joints, and both ends of the heat-shrink tube are overlapped, and then heat-sealed to the overlapped portion, The riveting on the steel plate also increased the cohesion and watertight strength of the step joint. In order to increase the degree of watertightness, as described above, the adhesive sheet should be placed on the stepped joints overlapped at both ends of the heat-shrink tube, and then heat-sealed, and then the binding member is bonded to the heat-sealed portion. The branch pipe is expected to reduce the cost by omitting expensive sheets of crosslinked yarn and replacing them with protective members.

In addition, the heat-shrinkable sheet is rolled in a circular shape, so that the heat-sealed portion is formed immediately by heat-sealing on the joint portion to be overlapped, and the purpose of the riveting the heat-sealed portion. In addition, an object of the present invention is to perform heat fusion molding on the joint portion without forming an adhesive sheet on the joint portion of the heat shrinkable sheet.

Fig. 4 is a plan view showing a longitudinal sectional view of the riveted state in which the heat shrinkable tube is bonded to the resin tubes, and FIG. 4 is a longitudinal sectional view showing a protection member adhered to the riveted riveted heat shrinkable tube of the present invention. In addition, Figure 5 is a longitudinal cross-sectional view of the protection member is bonded to the riveted riveted heat shrink tube of the present invention, the adhesive member is bonded to the inside, and also Figure 6a, b is a heat shrink tube of the present invention It is sectional drawing which showed the state bonded to the connection part of a resin pipe.

본 고안의 열수축관(100)은 도 1 에 나타낸 바와 같이 수지관(10,10)들의 양쪽 끝단 연결부분을 연결하기 위한 수단으로 사용되며, 도 6a,b에 나타낸 바와 같이 수지관(10,10)들의 연결부위에 열수축관(100)을 위치시킨 후, 열수축관(100)에 토오치 등의 열을 가하게 되면 수축되어 수지관(10,10)들의 연결부위를 수밀성있게 접착되게 된다.The heat shrink tube 100 of the present invention is used as a means for connecting both end connecting portions of the resin tubes 10 and 10 as shown in FIG. 1, and the resin tubes 10 and 10 as shown in FIGS. 6A and 6B. After placing the heat shrink tube 100 at the connection portion of the), when heat is applied to the heat shrink tube 100, such as torch is contracted to be tightly bonded to the connection portion of the resin tubes (10, 10).

우선, 열수축관(100)의 원단은 가교처리된 가교화 연신사로 구성되어진 경사와 면사 또는 그리스사로 구성되어진 위사를 직물화하여 양면이 가교된 폴리에틸렌 층사이에 적층 접착한 다음에 원단 그 자체를 연신 후 표면에 특수한 처리를 행하져 제작된다.First, the fabric of the heat-shrink tube 100 fabricates a warp yarn composed of crosslinked cross-linked stretched yarn and a weft yarn composed of cotton yarn or grease yarn, laminated on both sides of the crosslinked polyethylene layer, and then stretched the fabric itself. After that, the surface is made by special treatment.

그리고, 상기 열수축관용 원단은 가교화사는, 열이 가하여지면 수축되는 수축부재이고, 면사, 폴리에스터 또는 그라스사는 수축변형이 없는 재질로서 도 6a와 같이 열수축관(100)을 연결하고자 하는 수지관(10,10)의 연결부분에 위치시킨 후, 토오치 등의 가열수단에 의하여 면사, 폴리에스터 또는 그라스사쪽의 길이방향은 변형없이 수축부재인 가교화사가 수축되어 도 6b와 같이 수지관(10,10)들의 원주부분을 긴밀하게 압착하게 된다.And, the fabric for the heat shrink tube is a cross-linked yarn is a shrink member that is contracted when heat is applied, cotton yarn, polyester or glass yarn is a material that does not shrink shrink deformation, as shown in Figure 6a to the resin tube to connect the heat shrink tube ( 10, 10, the lengthwise direction of the cotton yarn, polyester or grass yarn by the heating means such as the torch shrinks without cross-linking cross-linked yarn is not deformed, as shown in Figure 6b 10) the circumferential portion of these is pressed closely.

본 고안의 열수축관의 접착구조는 도 2와 같이 열수축관(100)용 원단을 적당한 길이로 재단한 후, 양쪽 끝단을 겹쳐서 겹쳐진 부분에 열접착 수단에 의하여 열이 가하여지면서 누름력이 가하여지게 되면, 열성형 접착에 의하여 원단의 겹쳐진 부분에 열융착부분(110)이 성형되게 되며, 이로서 원형의 열수축관(100)을 구성하게 된다.When the adhesive structure of the heat shrinkable tube of the present invention is cut to a suitable length for the heat shrinkable tube 100 as shown in Figure 2, the pressing force is applied while heat is applied to the overlapped portions by heat bonding means By the thermoforming adhesion, the heat-sealed portion 110 is formed on the overlapped portions of the fabric, thereby forming a circular heat-shrink tube 100.

상기 열수축관(100)의 열융착부분(110)은 열이 가하여지면서 눌려져 겹쳐진 부분이 열융착되어 접촉되어 있기 때문에 어느 정도 접착 강성을 유지할 수 있으나, 앞서 설명한 바와 같이 열을 가하여 강제적으로 접착되어 있기 때문에 피로가 있고 또한 인장강도와 파열강도가 취약한 문제가 있다.Since the heat-sealed portion 110 of the heat-shrink tube 100 is pressed while being heated, the overlapped portions are in contact with each other by heat-sealing, but the adhesive rigidity can be maintained to a certain extent, but is forcibly bonded by applying heat as described above. Due to fatigue, there is also a problem in that tensile strength and bursting strength are weak.

본 고안은 상기 열수축관(100)의 양쪽 끝단이 겹쳐져 열융착되는 열융착부분(110)에 도 3a,b에 나타낸 바와 같이 리벳트(200)가 등간격으로 리벳팅되어 고정되도록 하여 위의 인장강도 및 파열강도의 문제를 해소할 수 있다.The present invention is such that both ends of the heat shrink tube 100 is overlapped and heat-sealed to the heat-sealed portion 110, as shown in Figure 3a, b as shown in Figure 3a, b riveted to be fixed at equal intervals above the tension The problem of strength and bursting strength can be solved.

상기 리벳트(200)처리 이전에 상기 열수축관(100)의 열융착부분(110)의 열융착되지 않은 잉여부분인 바깥끝단(120)은 절단하여도 된다.Before the rivet 200 treatment, the outer end 120, which is a non-heated excess portion of the heat-sealed portion 110 of the heat-shrink tube 100, may be cut.

즉, 상기 열수축관(100)의 열융착부분(110)에 리벳트(200)가 장착되어 있기 때문에, 도 6b와 같이 수지관(10,10)의 연결부위에 열수축관(100)이 접착되어 수지관(10,10)에 외압이 가하여져, 열수축관(100)에 인장력이 가하여지더라고 열융착부분(110)의 열융착력과 리벳트(200)의 결속력이 잡아주기 때문에, 열수축관(100)이 누수공간을 발생시키는 일이없게 된다.That is, since the rivet 200 is mounted on the heat-sealed portion 110 of the heat-shrink tube 100, the heat-shrink tube 100 is bonded to the connection portions of the resin tubes 10 and 10 as shown in FIG. Since the external pressure is applied to the resin tubes 10 and 10, and the tensile force is applied to the heat shrink tube 100, the heat fusion force of the heat fusion portion 110 and the binding force of the rivet 200 hold the heat shrink tube ( 100) does not generate a leak space.

또한, 본 고안은 도 4에 나타낸 바와 같이 열수축관(100)의 양쪽 끝단이 겹쳐져 열융착되는 열융착부분(110)에 리벳트(200)가 등간격으로 리벳팅되고, 상기 리벳팅된 부분의 위에 보호부재(300)가 고정되도록 하여 열융착부분(110)의 보호와 리벳트(200)부분을 보호할 수 있으며, 열수축관(100)안쪽의 끝단부위에 접착제(130)를 도포하여 열융착부분(110)의 접착력 및 누수의 공간을 보강할 수 있다. 상기 열융착부분(110)의 리벳트(200)의 장착으로 결속력이 유지되어 있기 때문에, 사실 상기 접착제(130)를 도포하지 않아도 된다.In addition, the present invention, as shown in Figure 4, the rivets 200 are riveted at equal intervals in the heat-sealed portion 110, both ends of the heat-shrink tube 100 is heat-sealed overlapping, the riveted portion of The protection member 300 is fixed thereon to protect the heat-sealed portion 110 and the rivet 200 portion, and heat-sealed by applying an adhesive 130 to the inner end portion of the heat-shrink tube 100. The adhesion of the portion 110 and the space of the leak can be reinforced. Since the binding force is maintained by the mounting of the rivet 200 of the heat-sealed portion 110, it is not necessary to apply the adhesive 130.

또한, 도 5에 나타낸 바와 같이 열수축관(100)의 열융착부분(110)의 내면에 점착부재(400)를 접착하면, 수지관(10,10)에 열수축관(100)의 접착시 상호 점착력을 증대시킬 수 있다.In addition, as shown in FIG. 5, when the adhesive member 400 is adhered to the inner surface of the heat-sealed portion 110 of the heat-shrinkable tube 100, the mutual adhesive force at the time of bonding the heat-shrinkable tube 100 to the resin tubes 10 and 10. Can be increased.

이상과 같이, 본 고안은 수지관들(P.E 하수관, P.E 우수관, P.E오수관, 통신관, 파형관, 파형강관 등)의 연결부분의 양쪽 끝단을 맞대어 열수축관이 열수축되어 접착되도록 함에 있어서의 열수축관의 양쪽끝단이 겹쳐져 열융착되는 부분에 부가하여 등간격으로 리벳트가 리벳팅되어 결속력이 증대토록하여, 열수축관이 수지관의 연결부분에 열수축 성형된 후, 수지관내에 외부의 온도와 큰 차이가 있는 온, 냉의 유통물 또는 화공약품 등이 유통되더라고 열수축관의 열융착부분이 이완되는 일이 없이 유지할 수 있는 동시에, 열융착부분의 리벳트가 열융착부분의 결속력을 증대시키어 수밀 강도를 높임으로서, 결국 열수축관의 인장강도와 파열강도를 높여, 수지관의 연결부위가 누수되는 것을 방지하여 반영구적인 수명을 가질 수 있다.As described above, the present invention is opposed to both ends of the connection portion of the resin pipes (PE sewer pipe, PE rain pipe, PE sewage pipe, communication pipe, corrugated pipe, corrugated steel pipe, etc.) so that the heat shrink pipe is heat-shrinked and bonded in both sides Rivets are riveted at equal intervals in addition to the parts where the ends overlap and heat-sealed to increase the binding force, and after the heat shrink tube is heat-shrink-molded at the connecting portion of the resin tube, there is a large difference with the outside temperature in the resin tube. Hot and cold distribution products or chemicals can be maintained without releasing the heat-sealed portion of the heat-shrinkable tube, and the rivets of the heat-sealed portion increase the binding force of the heat-sealed portion to increase the watertight strength. As a result, it is possible to increase the tensile strength and the bursting strength of the heat shrinkable tube, thereby preventing the connection portion of the resin tube from leaking and have a semi-permanent life.
