Abstract

A structure is provided for installing a pipe fixing clamp installed in a sound absorber. A part of a curved pipe portion of an internal structural pipe of the sound absorber is cut to form an exhaust gas flow space. The pipe fixing clamp having multiple holes is connected to the exhaust gas flow space.

First claim

What is claimed is:

1. A structure for use with a sound absorber, the structure comprising:
a first pipe portion of an internal structural pipe of the sound absorber;
a second pipe portion of the internal structural pipe of the sound absorber, the second pipe portion spaced from the first pipe portion; and
a pipe fixing clamp installed at a space between the first pipe portion and the second pipe portion, the pipe fixing clamp having multiple holes through which an interior and an exterior of the internal structural pipe can communicate with each other.

2. The structure of claim 1 , wherein the space is formed by cutting the internal structural pipe to separate the first pipe portion from the second pipe portion.

3. The structure of claim 1 , wherein the pipe fixing clamp is installed at the space so that exhaust gas can pass therethrough.

4. The structure of claim 1 , wherein the first and second pipe portions are spaced apart from each other such that exhaust gas passes through the holes positioned in the pipe fixing clamp.

5. The structure of claim 1 , wherein the first pipe portion comprises a curved pipe portion.

6. The structure of claim 5 , wherein the second pipe portion comprises a curved pipe portion.

7. A structure for use with a sound absorber, the structure comprising:
a first pipe portion of an internal structural pipe of the sound absorber;
a second pipe portion of the internal structural pipe of the sound absorber, the second pipe portion spaced from the first pipe portion;
a pipe fixing clamp installed at a space between the first pipe portion and the second pipe portion, the pipe fixing clamp having multiple holes through which an interior and an exterior of the internal structural pipe can communicate with each other;
a first rubber attached to the first pipe portion adjacent the space; and
a second rubber attached to the second pipe portion adjacent the space.

8. The structure of claim 7 , wherein the space is formed by cutting the internal structural pipe to separate the first pipe portion from the second pipe portion.

9. The structure of claim 7 , wherein the pipe fixing clamp is installed at the space so that exhaust gas can pass therethrough.

10. The structure of claim 7 , wherein the first and second pipe portions are spaced apart from each other such that exhaust gas passes through the holes positioned in the pipe fixing clamp.

11. The structure of claim 7 , wherein the first pipe portion comprises a curved pipe portion.

12. The structure of claim 11 , wherein the second pipe portion comprises a curved pipe portion.

13. A structure for use with a sound absorber, the structure comprising:
a first pipe portion of an internal structural pipe of the sound absorber;
a second pipe portion of the internal structural pipe of the sound absorber, the second pipe portion spaced from the first pipe portion; and
a pipe fixing clamp made of metal and installed at a space between the first pipe portion and the second pipe portion, the pipe fixing clamp having multiple holes through which an interior and an exterior of the internal structural pipe can communicate with each other.

14. The structure of claim 13 , wherein the space is formed by cutting the internal structural pipe to separate the first pipe portion from the second pipe portion.

15. The structure of claim 13 , wherein the pipe fixing clamp is installed at the space so that exhaust gas can pass therethrough.

16. The structure of claim 13 , wherein the first and second pipe portions are spaced apart from each other such that exhaust gas passes through the holes positioned in the pipe fixing clamp.

17. The structure of claim 13 , wherein the pipe fixing clamp has a metal band shape.

18. The structure of claim 17 , wherein the pipe fixing clamp is fastened by a bolt and a nut.

19. The structure of claim 13 , wherein the first pipe portion comprises a curved pipe portion.

20. The structure of claim 19 , wherein the second pipe portion comprises a curved pipe portion.
