본 발명은 송풍관 연결장치에 관한 것으로서, 더욱 더 상세하게 설명하면 터널공사나 지하철공사등 공사중에 매연 또는 가스가 발생되어 환기를 요하는 장소에 공기를 주입할 때 사용되는 공기주입용 호스(PAN DUCT)의 연결부위에 사용되는 것으로, 내측면에 양측으로 단턱이 형성되고, 이 단턱의 내측 모시리부에 안착부가 형성된 커프링에, 체결링이 공기주입용 호스의 일단에 봉합되어 서로 교차되게 상기 커프링의 안착부에 안착되게 설치함으로서, 체결이 견고하게 이루어지고, 조립이 간단하며, 운반이 용이함과 동시에 제작비 또한 절감되는 송풍관 연결장치에 관한 것이다.The present invention relates to a blower pipe connecting device, and in more detail, when a soot or gas is generated during construction such as a tunnel construction or subway construction, an air injection hose used to inject air into a place requiring ventilation (PAN DUCT) Cuff is formed at both sides of the inner surface, and the cuff ring formed with a seating portion at the inner side of the stepped portion is fastened to one end of the air injection hose and crosses the cuff. By installing to be seated on the seating portion of the ring, the fastening is made, the assembly is simple, easy to transport and at the same time the manufacturing cost is also related to a blow pipe connection device.
일반적으로, 터널공사현장이나 지하철공사현장등 밀폐된 작업현장에서 작업을 하는 작업자는 작업현장에서 발생되는 먼지나 매연 또는 가스등을 직접 흡입하면서 작업을 해야하기 때문에 작업의 능률저하 및 인체에 유해한 공기를 흡입하는 관계로 여러 질병의 원인이 되어 많은 작업자들이 꺼려하는 현장이 되어야만 했다.In general, workers who work in enclosed workplaces such as tunnel construction sites or subway construction sites must work by directly inhaling dust, smoke, or gas generated at the work sites, which reduces work efficiency and harmful air. Inhalation had to be the cause of many diseases and a lot of workers are reluctant.
이러한 문제점을 해소 하고자 공기주입용 호스를 사용하여 작업현장에 신선한 공기를 주입하는 방법이 채택되어 사용되었는데, 작업현장의 길이가 길다보니 상기 공기주입용 호스를 상호 연결하여 사용하여야만 했다.In order to solve this problem, a method of injecting fresh air into the work site using an air injection hose was adopted and used. Since the length of the work site was long, the air injection hose had to be interconnected.
상기와 같이 공기주입용 호스를 상호 연결할 수 있는 종래의 송풍관 연결장치는 제3도 및 제4도에 도시된 바와 같이 내측면에 안치부(32)가 형성되고, 이 안치부(32)의 양단을 절곡하여 가이드(34)를 형성하며, 일측이 개방되어 있는 몸체(36)에, 이 몸체(36)의 개방된 끝단으로 나선공(37)이 형성되어 체결되게 체결브라켓(38)이 용접되거나 나사결합되어 체결핀(39)으로 체결할 수 있는 커프링(40)을 사용하여, 먼저 하나의 체결링(50)에 공기주입용 호스(30)의 일측을 감싸고, 다른 공기주입용 호스(30a)의 일단을 올려 놓은 다음 상기 커프링(40)의 안치부(32)에 삽입한 후, 양측에 나선공(37)이 형성되어 결합된 체결브라켓(38)의 나선공(37)으로 체결핀(39)을 사용하여 결합하여 사용하였다.In the conventional blower pipe connecting device capable of interconnecting the air injection hose as described above, as shown in FIG. 3 and FIG. 4, a settling part 32 is formed on the inner side, and both ends of the settling part 32 are formed. To form the guide 34 by bending, one side is open, the fastening bracket 38 is welded or welded to form a spiral hole 37 is fastened to the open end of the body 36, Using a cuff ring 40 that can be screwed and fastened with fastening pins 39, first wrap one side of the air injection hose 30 in one fastening ring 50, and the other air injection hose 30a. 1) put one end of the cuff ring 40, and then inserted into the settled portion 32 of the cuff ring 40, the spiral hole 37 is formed on both sides of the fastening pin with the spiral hole 37 of the fastening bracket 38 is coupled (39) was used in combination.
그러나, 종래의 송풍관 연결장치는 작업자가 작업을 하는 과정에서 조립이 불편할 뿐만 아니라 재질 자체도 금속재로 되어 있어, 사용도중에 찌그러지거나 체결브라켓(38)의 결합이 제대로 이루어지지 않았을 경우에는 체결이 불량하였으며, 커프링(40)으로 공기주입용 호스(30, 30a)가 체결된 상태에서는 공기주입용 호스(30, 30a)내로 주입된 공기의 압력에 의해 상기 공기주입용 호스(30a)가 커프링(40)에서 빠지는 문제점이 발생하였다.However, the conventional blower pipe connecting device is not only inconvenient to assemble in the process of the operator work, but also the material itself is made of a metal material, if the crushed during use or when the coupling of the fastening bracket 38 is not properly made, the fastening was poor. In the state in which the air injection hoses 30 and 30a are fastened by the cuff ring 40, the air injection hose 30a is cuffed by the pressure of the air injected into the air injection hoses 30 and 30a. There was a problem of missing in 40).
또한, 재질이 금속재로 되어있어 송풍관 커질 경우에는 그에 따라 커프링(40)의 사이즈가 커져 운반을 하는데는 많은 어려움이 발생하였으며, 제작비도 많이 소요되는 문제점등이 초래되었다.In addition, when the material is made of a metal material and the air blower tube is enlarged accordingly, the size of the cuff ring 40 is increased, which causes a lot of difficulties in carrying, and also causes a lot of manufacturing costs.
본 발명은 상기와 같은 제반 문제점을 해소 하고자 안출된 것으로서, 터널공사나 지하철공사등 공사중에 매연 또는 가스가 발생되어 환기를 요하는 장소에 공기를 주입할 때 사용되는 공기주입용 호스의 연결부위에 사용되는 것으로, 체결이 견고하게 이루어지고, 조립이 간단하며, 운반이 용이함과 동시에 제작비 또한 절감되도록 하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, to the connection part of the air injection hose used when injecting air to a place requiring ventilation by the generation of smoke or gas during construction such as tunnel construction or subway construction It is to be used, the fastening is made, the assembly is simple, easy to transport and at the same time the production cost is to be reduced.
상기와 같은 목적을 달성하기 위한 본 발명은 내측면에 양측으로 단턱이 형성되고, 이 단턱의 내측 모서리부에 안착부가 형성된 커프링에, 체결링이 공기주입용 호스의 일단에 봉합되어 서로 교차되게 상기 커프링의 안착부에 안착되게 설치되는 것이 특징이다.In order to achieve the above object, the present invention has a stepped jaw formed at both sides on the inner side, and a cuff ring formed with a seating portion at the inner edge of the stepped jaw, the fastening ring is sewn at one end of the air injection hose to cross each other. It is characterized in that it is installed to be seated in the seating portion of the cuff ring.
이하, 첨부된 도면에 의해 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, the preferred embodiment of the present invention with reference to the accompanying drawings as follows.
제1도는 본 발명 설치상태의 분해사시도를, 제2도는 본 발명 체결상태의 요부단면도를 도시한 것으로서, 내측면에 양측으로 단턱(2)이 형성되고, 이 단턱(2)의 내측 모서리부에 안착부(4, 4a)가 형성된 커프링(10)에, 체결링(50, 50a)이 공기주입용 호스(30, 30a)의 일단으로 봉합되어 서로 교차되어 상기 커프링(10)의 안착부(4, 4a)에 안착되게 설치되는 것을 도시한 것이다.1 is an exploded perspective view of the installation state of the present invention, Figure 2 is a main cross-sectional view of the fastening state of the present invention, the stepped portion 2 is formed on both sides on the inner side, the inner edge of the stepped portion 2 In the cuff ring 10 in which the seating portions 4 and 4a are formed, the fastening rings 50 and 50a are sealed with one end of the air injection hoses 30 and 30a and cross each other so that the seating portion of the cuff ring 10 can be crossed. (4, 4a) is shown to be installed to be seated.
상기와 같이 설치된 본 발명의 작용효과를 첨부된 도면 제1도 및 제2도에 의해 설명하면 다음과 같다.Referring to the effects of the present invention installed as described above with reference to Figures 1 and 2 as follows.
일단에 체결링(50, 50a)이 봉합되어 있는 공기주입용 호스(30, 30a)를 서로 교차되게 즉, 하나의 체결링(50)을 다른 하나의 체결링(50a)으로 삽입하여 교차시킨 후에, 상기 커프링(10)의 일측 안착부(4)에 체결링(50)을 타측 안착부(4a)에 체결링(50a)을 안착시키면 체결이 완료되는 것이다.After interlocking the air injection hoses 30 and 30a having the fastening rings 50 and 50a sealed at one end thereof, that is, inserting one fastening ring 50 into the other fastening ring 50a and When the fastening ring 50 is seated on one seating part 4 of the cuff ring 10, the fastening ring 50a is seated on the other seating part 4a to complete the fastening.
이와같이 체결이 완료되어 공기주입용 호스(30, 30a) 내로 공기가 주입되면 탄성재로된 커프링(10)의 일측 안착부(4)에 안착된 체결링(50)이 공기의 압력으로 안착부(4)측으로 밀착되고, 타측의 안착부(4a)에 안착되어 있는 체결링(50a)은 안착부(4a)측으로 밀착되어 더욱 더 견고하게 체결링(50, 50a)이 커프링(10)이 체결되는 것이다.When the fastening is completed and air is injected into the air injection hoses 30 and 30a, the fastening ring 50 seated on one seating part 4 of the cuff ring 10 made of elastic material is seated by the pressure of air. The fastening ring 50a which is in close contact with the (4) side and is seated at the seating part 4a on the other side is in close contact with the seating part 4a, and the fastening rings 50 and 50a are more firmly connected to the cuff ring 10. It is fastened.
또한, 탄성재로된 커프링(10)은 사이즈가 커지더라도 접어서 운반할 수 있는 장점이 있다.In addition, the cuff ring 10 made of an elastic material has an advantage that can be folded and carried even if the size is increased.
상술한 바와 같이 커버링의 내측으로 체결링의 체결이 견고하게 이루어지고, 조립이 간단하며, 운반이 용이함과 동시에 제작비 또한 절감할 수 있는 유용한 발명인 것이다.As described above, the fastening of the fastening ring is made to the inner side of the covering, it is a useful invention that is easy to assemble, easy to carry and reduce the production cost at the same time.
