Description
본 고안은 덕트 연결용 클램프에 관한 것으로, 더욱 상세하게는 반원형으로 된 한쌍의 체결밴드로 구성하여 덕트의 이음새를 양측에서 감싼 상태에서 일단을 먼저 결합시키고 타단을 체결구에 의해 나사체결할 수 있도록 하여 협소한 공간에서도 조립 및 분해의 작업성이 편리하도록 된 한쌍의 체결밴드로 된 덕트연결용 클램프에 관한 것이다.The present invention relates to a clamp for connecting the duct, more specifically, consisting of a pair of fastening bands of semi-circular shape, so that one end can be joined first and the other end can be screwed by the fastener while the seam of the duct is wrapped on both sides. Therefore, the present invention relates to a duct connection clamp consisting of a pair of fastening bands, which facilitates assembly and disassembly even in a narrow space.
공기조화 장치에 있어서 덕트는 공기나 기타 유체가 흐르는 통로 및 구조물로서 주로 건물 등의 실내와 외부를 연통시켜 공기를 순환 정화시키는 역할을 하며 환풍기나 냉난방장치의 공기 이동통로로 사용된다.In the air conditioning system, the duct is a passage and structure through which air or other fluids flow, and mainly serves to circulate and purify the air by communicating with the inside and outside of a building, and is used as an air moving passage of a fan or an air conditioner.
상기 덕트를 상호 연결할 때나 덕트에 다른 피고정물을 연결할 때 연결이음새 부분을 조여 안정되게 결합시키는 것이 덕트연결용 클램프이다.When the ducts are interconnected or when other fixtures are connected to the ducts, the clamps for duct connection are tightened to stably connect the joints.
상기 덕트는 단면이 직사각형이나 타원형인 것이 있으나 특히 원형으로 된 원통형의 관으로 된 것이 많이 사용되고 있고, 덕트 속을 흐르는 공기의 온도가 그 주위의 온도와 차이가 있기 때문에 일어나는 열의 이동을 막고자 할 때는 덕트의 둘레에 단열재 등을 감아 사용하기도 한다. 재질로서는 보통 아연철판재가 많이 쓰이지만 때로는 염화비닐 또는 유리섬유도 사용된다.The duct is rectangular or elliptical in cross section, but is particularly used in the form of a circular cylindrical tube, and in order to prevent the heat transfer caused by the temperature of the air flowing in the duct is different from the temperature around it. It is also possible to wind insulation around the duct. Galvanized sheet is usually used as a material, but sometimes vinyl chloride or glass fiber is also used.
상기 덕트를 이용하여 공기 순환 통로를 형성하기 위해서는 다수의 덕트를조합 연결하는데, 이때 덕트 양단이 억지끼움되어 연결되는 것은 끼움부 외주를 클램프로 조여 결속시키게 되며 덕트의 양단에 결합플랜지가 형성된 것을 연결하기 위하여는 결합플랜지를 상호 맞댄 후 이를 수용하는 홈을 가진 클램프로 그 외주를 깜싸 결속할 수 있도록 되어 있다.In order to form an air circulation passage using the duct, a plurality of ducts are combined and connected, where both ends of the duct are connected to each other by being clamped by clamping the outer periphery of the fitting and connecting the coupling flanges formed at both ends of the duct. In order to achieve this, the coupling flanges can be joined to each other, and then a clamp having a groove for accommodating them can be used to bind the outer periphery.
도 7은 양단에 결합플랜지가 형성된 덕트를 결합시키기 위한 종래 덕트 연결용 클램프의 사시도를 도시한 것으로, 종래 클램프는 덕트의 결합플랜지를 내측에 수용할 수 있는 보강테(1)를 가진 원형의 띠형상으로 일측을 절단한 후 절단면을 외측으로 소정길이 절곡하고 그 절곡부(2)에 체결구멍(3)을 형성하여 볼트 및 너트로 된 체결구(4)에 의해 체결 조임되도록 되어 있다.Figure 7 shows a perspective view of a conventional duct connecting clamp for joining the duct formed in the coupling flange at both ends, the conventional clamp is a circular strip having a reinforcing frame (1) that can accommodate the coupling flange of the duct inside After cutting one side into a shape, the cut surface is bent outward by a predetermined length, and a fastening hole 3 is formed in the bent portion 2 to be fastened and tightened by a fastener 4 made of a bolt and a nut.
상기 구조의 클램프는 절곡부(2)가 얇은 금속판을 절곡시킨 1겹으로 되어 있어 체결시 강성이 약해 쉽게 휘어지게 되며 이로인한 체결력이 약해지는 문제가 발생된다. 또 하나의 원형으로 되어 있기 때문에 일측 절단부(2)의 벌림이 한정되어 덕트의 외측에서 억지끼움을 할시에는 외형의 비틀림 등 손상이 가게 되며 절곡부(2)가 외측으로 돌출되어 있어 도 8과 같이 벽체에 근접되게 설치시에는 클램프를 미리 어느 한쪽의 덕트에 끼운채로 덕트를 벽체에 근접시켜 조립하여야 하기 때문에 클램프가 작업과정에서 걸리게 되어 작업효율이 떨어지는 문제가 발생된다.The clamp of the above structure is a bending part 2 is made of one layer of bending a thin metal plate, the rigidity at the time of fastening is easy to bend, thereby causing a problem of weakening the fastening force. Since the circular shape of the one side cutout part 2 is limited because the circular shape of the cutout part 2 is limited, twisting or the like of the external shape may be damaged, and the bent part 2 protrudes outward as shown in FIG. 8. When installed in close proximity to the wall, while the clamp must be assembled in close proximity to the duct with one of the ducts in advance, the clamp is caught in the work process, the problem of work efficiency is reduced.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 고안된 것으로서그 목적으로 하는 것은, 2개로 분리되어 반원형으로 된 한쌍의 체결밴드로 구성하여 덕트를 벽에 근접시켜 뒤측 공간이 협소한 상태에서도 양측부에서 상호 용이하게 결속시켜 덕트 이음새를 감싸 체결할 수 있음은 물론 펀칭의 방법으로 고정판부를 2겹으로 형성하여 강성을 보완함으로써 체결구 조임시 휨이 없이 덕트를 단단하고 안정되게 연결할 수 있는 한쌍의 체결밴드로 된 덕트연결용 클램프를 제공하고자 하는 것에 있다.The present invention is designed to solve the conventional problems as described above, and its purpose is to consist of a pair of fastening bands separated into two semi-circular shape to close the duct to the wall, even in the state where the rear space is narrow In addition, it is possible to fasten the duct seam by fastening each other at the same time, as well as to fix the stiffness by forming two layers of fixing plate by punching method, and to connect the duct tightly and stably without bending when tightening the fastener. An object of the present invention is to provide a clamp for connecting a duct in a band.

이하 본 고안의 구체적인 일 실시 예를 도면에 따라서 상세히 설명한다.Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the drawings.
도 1은 본 고안에 따른 덕트 연결용 클램프의 사시도이고, 도 2는 도 1의 분리사시도를 각각 도시하고 있다.1 is a perspective view of a clamp for duct connection according to the present invention, Figure 2 shows an exploded perspective view of Figure 1 respectively.
도시한 바와 같이, 본 고안의 덕트연결용 클램프는 소정폭을 가진 띠형상이며 그 외주면은 중심외측으로 돌출되어 내측오목홈(12a)을 가지도록 보강테(12)가 형성된 2개로 분리되어 반원형으로 된 한쌍의 체결밴드(10,11)로 구성된다.As shown, the duct connection clamp of the present invention is a band shape having a predetermined width and its outer peripheral surface is separated into two semi-circular shape formed by two reinforcing frames 12 are formed so as to have an inner concave groove 12a. It consists of a pair of fastening bands (10, 11).
상기 2개의 체결밴드(10,11)는 상호 마주보는 형태로 결합되어 덕트의 이음새 외주면을 감싸조일 수 있게 되며 이때 결합을 위한 체결밴드(10,11)의 마주보는 각 단은 결합부와 체결부를 이루게 된다.The two fastening bands 10 and 11 are coupled to face each other to be wrapped around the outer circumferential surface of the duct, and the opposite ends of the fastening bands 10 and 11 for the coupling are combined and fastening portions. Is achieved.
이를 위해, 상기 2개의 체결밴드(10,11) 중 하나의 체결밴드(10)는 그 길이방향 일단부 가까이에 삽입판(10a)이 형성되고 길이방향 타단부에는 직경방향 외측으로 돌출되게 고정구멍(10c)을 갖는 2겹의 고정판부(10b)가 형성된다. 여기서 상기 삽입판(10a)은 도 3과 같이 보강테(12)의 상,하면에 외측에서 내측으로 펀칭작업을 하는 것에 의해 "┗"형의 돌기를 형성하게 되며, 고정판부(10b)는 내측에서 외측으로 펀칭작업을 실시하여 2겹으로 접힘과 동시에 펀칭된 돌부 외면은 보강테(12)의 돌출외면과 동일면이 되도록 펀칭한다. 이때 삽입판(10a)은 길이방향으로 상,하 2쌍을 펀칭하여 후술하는 수용판(11a)에 견고하게 결합될 수 있도록 하는 것이 바람직하다. 그리고 2겹으로 된 고정판부(10b)는 장력에도 휘지 않는 보강력을 갖게 되며 펀칭시 약간 벌어진 상태지만 고정구멍(10c)의 천공을 위한 펀칭과정에서 2겹이 서로 포개진 상태가 된다.To this end, one of the fastening bands 10 of the two fastening bands 10 and 11 has an insertion plate 10a formed near its one end in the longitudinal direction and a fixing hole protruding outward in the radial direction at the other end of the longitudinal direction. The two-ply fixing plate part 10b which has 10c is formed. Here, the insertion plate 10a forms a “┗” shaped protrusion by punching from the outside to the inside on the upper and lower surfaces of the reinforcing frame 12 as shown in FIG. 3, and the fixing plate portion 10b has an inner side. Punching work is carried out in the outer side to be folded in two layers and punched at the same time the outer surface punched to be the same surface as the protruding outer surface of the reinforcing frame (12). At this time, the insertion plate 10a is preferably punched up and down two pairs in the longitudinal direction to be firmly coupled to the receiving plate (11a) to be described later. The two-ply fixed plate part 10b has a reinforcement force that does not bend even in tension and is slightly opened during punching, but the two-ply fixed plate part 10b overlaps each other in the punching process for the drilling of the fixing hole 10c.
다른 하나의 체결밴드(11)는 상기와 동일한 과정을 거쳐 이루어지며 그 길이방향 일단부 가까이에 상기 삽입판(10a)이 결합될 수 있는 수용판(11a)을 형성하고 길이방향 타단부에는 직경방향 외측으로 돌출되게 고정구멍(11c)을 갖는 2겹의 고정판부(11b)를 형성한다. 여기서 수용판(11a)은 도 3과 같이 내측에서 외측으로 펀칭을 실시하여 상기 삽입판(10a)을 삽입시킬 수 있는 대응된 위치에 "┓"형의 홈형태로 펀칭되며, 고정판부(11b)는 위와 마찬가지로 내측에서 외측으로 펀칭작업을 실시하여 2겹으로 접힘과 동시에 펀칭된 돌부 외면은 보강테(12)의 돌출외면과 동일면이 되도록 펀칭된다.The other fastening band 11 is formed through the same process as described above, and forms a receiving plate 11a to which the insertion plate 10a can be coupled near one end in the longitudinal direction thereof, and the other end in the longitudinal direction thereof in the radial direction. Two layers of fixing plate portions 11b having fixing holes 11c are formed to protrude outward. Here, the receiving plate 11a is punched in the form of a groove of a “┓” type at a corresponding position where the insertion plate 10a can be inserted by punching from the inside to the outside as shown in FIG. 3, and the fixed plate portion 11b is provided.
