DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for fixing a supply / exhaust pipe of a combustor having supply / exhaust pipes arranged in parallel on a wall or the like.

[0002]

2. Description of the Related Art A conventional exhaust pipe fixing device of this type is shown in FIG.
As shown in FIG. 7, the air supply pipe 31 and the exhaust pipe 32 are
3 and is fixed by screws to the wall surface 34. The holding bracket 33 is formed by joining two brackets 33A and 33B with a circular recess 35 for fitting the supply / exhaust pipe into a tied state. Thus, the supply and exhaust pipes 31 and 32 are integrally held and fixed to the wall surface 34 by being integrated with the wall fixing screws 36.

[0003]

However, in the above-mentioned conventional supply / exhaust pipe fixing device, the two fittings 33A and 33B must be fitted to the supply pipe 31 and the exhaust pipe 32, respectively, and then joined together, and then integrated with the screw 36. In addition, the metal fitting 33B on the wall surface 34 side supplies the circular recess 35B in a narrow space between the supply / exhaust pipes 31, 32 and the wall surface 34A.
It had to be fitted to the exhaust pipe, and there was a problem that workability was very poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its first object to improve workability. It is also a second object of the present invention to enable the supply and exhaust pipes to be integrally held.

[0005]

In order to achieve the first object, the present invention provides an air supply pipe and an exhaust pipe which are arranged in parallel along a wall or the like, and these two pipes are connected and held to form the wall or the like. And a holding bracket for fixing the holding bracket.
The exhaust pipe includes two circular recesses to be fitted respectively, and a wall mounting portion formed continuously with the circular recesses, and each of the circular recesses surrounds the circumference of the supply / exhaust pipe by 180 degrees or more. In order to achieve the second object, the holding metal fitting is provided with a U-shaped metal fitting so as to straddle between wall mounting portions of the holding metal fitting. The structure is such that the space between the wall mounting portions of the holding fitting is prevented from widening.

[0006]

According to the present invention, when the circular recess of the holding fitting is strongly pushed into the supply / exhaust pipe, the circular recess fits into the supply / exhaust pipe to hold them integrally. If the part is fixed to a wall surface or the like, the supply / exhaust pipe can be firmly fixed and held, and the work can be performed from the front side, so that the workability is remarkably improved.

Also, in the case where the U-shaped metal fitting is set between the wall mounting parts of the holding metal, the spread between the wall mounting parts can be prevented, and when the wall is a sliding door or the like, the holding is performed. Even when the wall mounting portion of the fitting cannot be fixed, only the supply / exhaust pipe can be reliably held.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 5, reference numeral 1 denotes an air supply pipe, 2 denotes an exhaust pipe, and both pipes are arranged in parallel along the wall surface 3 to communicate a combustor (not shown) with the outside. It is.

Reference numeral 4 denotes a holding bracket for integrally holding the supply / exhaust pipes 1, 2; two holding parts 4A, 4B for fitting the supply / exhaust pipes 1, 2 respectively; It has continuously formed wall mounting portions 4C and 4D and spacer portions 4E located between the circular recesses 4A and 4B. Each of the circular recesses 4A and 4B of the holding fitting 4 has a circular shape surrounding the supply and exhaust pipes 1 and 2 by 180 degrees or more, and is configured to elastically hold the supply and exhaust pipes 1 and 2; In addition, a through hole (not shown) is formed in one wall mounting portion 4D, and a resin-made cord holder 5 is mounted.

Reference numeral 6 denotes a screw for fixing the wall mounting portions 4C and 4D of the holding fitting 4 to the wall 3. Reference numeral 7 denotes a U-shaped metal fitting which is attached so as to straddle between the wall mounting portions 4C and 4D of the holding metal member 4, and prevents an interval between the wall mounting portions 4C and 4D of the holding metal member 4 from expanding. Reference numeral 8 denotes an electric cord held by the cord holder 5 for passing a weak electric current for detecting exhaust pipe detachment. 9 is a cover cylinder for heat insulation.

In the above configuration, the holding metal fittings 4 are firstly arranged in parallel with each other along the wall surface 3,
The circular recesses 4A and 4B are pushed into the fitting 2 from the front side of the fitting 2 to be fitted therein, and the supply / exhaust pipes 1 and 2 are integrally held. Next, the wall mounting portions 4C and 4D are fixed to the wall surface 3 with screws 6 to complete the mounting. In this embodiment, the cord holder 5 is provided with an electric cord 8 for detecting exhaust pipe detachment.
Is fitted.

On the other hand, when the wall on which the supply / exhaust pipes 1 and 2 are arranged cannot be screwed to the wall mounting portions 4C and 4D like a sliding door or a glass window, as shown in FIGS. The U-shaped bracket 7 is attached between the wall mounting portions 4C and 4D. As a result, the holding bracket 4 is attached to the wall mounting portion 4 thereof.
Even if the C and 4D are not screwed, the space between the wall mounting portions 4C and 4D will not be widened, and even if an external force is applied to either of the supply / exhaust pipes 1 or 2, the holding fitting 4
From the circular recesses 4A and 4B. That is, the supply and exhaust pipes 1 and 2 can be reliably held. In this case, since the positions of the supply / exhaust pipes 1 and 2 are regulated by fixing them to the combustor (not shown) and the outside through the wall, there is a practical problem even if they are not fixed with screws or the like. Absent.

[0013]

As is apparent from the above description of the embodiment, the supply / exhaust pipe fixing device of the present invention can hold the supply / exhaust pipe integrally with one holding fitting, and the holding fitting has a circular concave portion. By simply pressing the gas supply and exhaust pipes into the supply and exhaust pipes, the circular recess fits in the supply and exhaust pipes and holds them together.If the wall mounting parts on both sides are fixed to the wall, etc., the supply and exhaust pipes will be strong In addition to being able to be fixed, the work can be performed from the front side, so that workability is significantly improved.

Further, in the case where the U-shaped metal fitting is set between the wall mounting parts of the holding metal, the spread between the wall mounting parts can be prevented. Even when it is impossible to fix the wall mounting portion of the holding fitting, only the supply / exhaust pipe can be reliably held, and can be used with confidence.

Further, in the case where the wall mounting portion is provided with a cord holder, there is an advantage that an electric cord or the like can be held by using the wall mounting portion.
