It relates to a communication connecting device for a gas combustion device for guiding the communication into a central portion of a connecting portion.

In general, since exhaust gas burned and discharged from a boiler contains toxic substances, a flue pipe is connected to an exhaust pipe of the boiler to discharge the exhaust gas to the outside so that the exhaust gas can be discharged to the outside.

At this time, since the length of the exhaust pipe is relatively short, a flue pipe is formed extending from the exhaust pipe, and the exhaust gas is discharged to the outdoors through the flue pipe.

Patent Document 1 relates to a connection structure between a conventional exhaust pipe and flue pipe. Referring to this, an exhaust pipe connected to discharge exhaust gas in a boiler to the outside of the boiler in a hollow tubular shape, and a hollow tubular body inserted into the exhaust pipe and coupled. , a flue pipe that guides the exhaust gas discharged through the exhaust pipe to move outdoors, an airtight band that is closely formed along the joint between the exhaust pipe and the flue pipe and closes the gap, and is formed to cover the airtight band so that the airtight band is formed to cover the exhaust pipe. It consists of a clamp that adheres closely to the joint between the flue pipe and the flue pipe.

At this time, the airtight band is bent to correspond to the height of the step between the exhaust pipe and the flue pipe, and adheres to the outer surfaces of the exhaust pipe and the flue pipe, and is press-fitted into the airtight band support part of the clamp in that state to form the airtight band to correspond to the height of the exhaust pipe and the flue pipe. tightly adhered to

Then, the gap between the exhaust pipe and the flue pipe is firmly sealed by the airtight band, and leakage of exhaust gas into the room through the gap between the exhaust pipe and the flue pipe is prevented.

However, in Patent Document 1 as described above, when the flue pipe enters the exhaust pipe, the lower end of the flue pipe is rubbed against the inner circumferential surface of the exhaust pipe as the flue pipe flows within the exhaust pipe, and the inner circumferential surface of the exhaust pipe on which the flue pipe is rubbed is damaged or cut due to excessive friction. There is a concern. At this time, thermal deformation occurs at the damaged part of the exhaust pipe due to the high-temperature exhaust gas discharged through the exhaust pipe and the flue pipe, causing a gap between the exhaust pipe and the flue pipe to widen or exhaust gas to the outside through the incision. There is a risk of leaking into the flue pipe, and in particular, the flue pipe moving downward in one direction in the exhaust pipe is caught in the packing groove, and the entry of the flue pipe may be restricted. Accordingly, it is difficult to stably enter the flue pipe into the exhaust pipe. There are difficulties, and there is a problem in that reliability of the product is lowered.
