However, since the existing "V" type connection band is formed by bending the bracket integrally or fixing it by spot welding and fastening it using bolts and nuts, it is possible to insert the bolts if both brackets are not horizontal during assembly. There is a difficulty, and there is inconvenience of continuing the repetitive tightening work in order to narrow the gap between the brackets.

In addition, in the case of the existing "V"-type connection band, as shown in FIG. 3, the bending stress due to the communication self-weight is applied to the band of the communication connection part because it is in a form that supports the bending stress at the end of the flange 120. When concentrated, a phenomenon in which the lower fastening part is separated from the band due to a bending moment occurs, and as a result, in the V-groove 130 of the connection band 100, an opening phenomenon due to pressure, shock, and weight occurs, and the connection band ( 100), as well as leakage, condensation, and leakage.

In other words, when the existing "V" type connection band is installed in a horizontal main pipe (horizontal flue), flexural stress is concentrated at the lower end of the fastening part due to the self-weight of the communication, the number of condensation, shock, and vibration, so that the communication flange forming part and the band are frequently separated. There is a problem that there is always the risk of an accident.

In addition, since the sealing silicone is filled inside the connection band, there is a problem in that the silicone leaks to the outside due to internal pressure during tightening.

First, as shown in FIGS. 4 to 7, the band 100 for bundling different diameter pipes of the present invention closely connects a plurality of pipes having different diameters.

To this end, the band 100 is composed of a first binding means 101 and a second binding means 102 having a length made of a metal material.

That is, the band 100 is composed of a first binding means 101 and a second binding means 102, and maintains a state of being connected to each other by the connecting means 150.

The configurations of the first binding means 101 and the second binding means 102 are as follows.

It is made of 110 free-bending and lengthy bands.

Here, the belt 110 can be plastically deformed so that its shape is maintained when it is bent or bent.

Further, a bent portion 130 and a locking portion 140 are formed on both sides of the belt 110, so that the bent portion 130 passes through the locking portion 140 and then bends to compress and bundle the outer periphery of the pipe pipe.

The first binding means 101 and the second binding means 102 configured as described above are arranged on a horizontal line, and the first binding means 101 and the second binding means 102 are connected to each other through the connecting means 150.

It is possible to change the diameter for the bundle of the first binding means 101 and the second binding means 102 through the connecting means 150.

To this end, the coupling means 150 is provided in plural, and one side of the coupling means 150 is integrally formed with the first coupling means 101 to be connected.

In addition, the other side of the coupling means 150 is coupled to the through portion 152 formed by bending the plurality of guide members 151 alternately so that the second fastening means 102 penetrates.

The band 100 configured as described above is installed to be bundled with the joints of pipes having different diameters.

That is, according to the diameter of the pipe, the first binding means 101 and the second binding means 102 are bundled, respectively, and the tip 131 is bent to regulate the bundled state.

In addition, the first binding means 101 and the second binding means 102 can maintain a connected state through the connection means 150 to maintain the connection state of the pipes to be connected.

A specific configuration of the first binding means 101 and the second binding means 102 includes a belt 110, a bent portion 130, a locking portion 140, and a binding portion 170.

The band 110 is made of a metal material, can be freely bent, and has a length.

The bent part 130 is formed on one side of the band 110, and the tip 131 is sharply formed.

The locking part 140 is formed on the other side of the belt 110 and forms a coupling hole 141 through which the bent part 130 passes.

The binding part 170 is formed behind the bent part 130 and penetrates through the locking part 140 to press the bent part 130.

Through the configuration as described above, the belt 110 surrounds the outer periphery of the pipe and penetrates the bent part 130 formed on one side of the belt 110 through the coupling hole 141 of the locking part 140.

Through this, the belt 110 is bound to the outer periphery of the pipe once, and when the bent part 130 that has passed through the coupling hole 141 is bent, the bundled state of the belt 110 is regulated.

Finally, the bent part 130 bent through the coupling hole 141 is inserted into the binding part 170 installed on the belt 110 to closely maintain the bending state of the bent part 130.

In addition, it is possible to closely bundle the first fastening means 101 and the second fastening means 102 to the pipe pipe through the fixing means 160 formed as projections or grooves at the rear of the locking part 140 and the bent part 130, respectively.

In other words, if the bent part 130 penetrates the coupling hole 141 of the locking part 140 and then presses the fixing means 160 close to each other using a tool or hand, the belt 110 further presses the outer periphery of the pipe and at the same time bends the bent part 130, the belt 110 can tie the outer periphery of the pipe more tightly.

A detailed function of the band 100 configured as described above will be described below.

Pipes with different diameters are connected in a straight line.

Here, each pair of pipes has a different diameter. The reason is that the outer periphery of one pipe is fitted to the inner periphery of the pipe for the connection.

Through this, the diameters of the pipes to be connected are different.

That is, if the two pipes to be connected are referred to as the first pipe 10 and the second pipe 12, the first binding means 101 is bound to the outer periphery of the first pipe 10, and the second binding means 102 is connected to the second pipe 12. It should be tied to the outer periphery.

Here, an O-ring is installed between the first pipe and the second pipe to prevent gas from leaking to the outside.

To this end, the bent portions 130 of each of the first fastening means 101 and the second fastening means 102 pass through the engaging holes 141 of the locking parts 140.

In addition, when the fixing means 160 is pressed close to each other using a tool or a hand, the belt 110 further presses the outer periphery of the pipe, and at the same time, when the bent portion 130 is bent, the belt 110 can more closely tie the outer periphery of the pipe.

Next, the belt 110 is bundled around the outer periphery of the pipe, and the bent part 130 that has passed through the coupling hole 141 is bent to regulate the bundled state of the belt 110.

Finally, the bent part 130 bent through the coupling hole 141 is inserted into the binding part 170 installed on the belt 110 to closely maintain the bending state of the bent part 130.

As described above, pipes of different diameters are tightly bundled through the band 100, so that the connection state of the pipes can be firmly maintained.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and various substitutions, modifications and changes are possible within the scope of the technical spirit of the present invention. It will be obvious to those who have the knowledge of.
