Referring to the first to tenth drawings, when the creation is in the fabric, first, as shown in the first to third figures, the pillars 11 of the frame group 1 are welded and connected to the casing in a spaced manner. 7 the side surfaces, and the through holes 112 provided on the side surfaces of the pillars 11 are respectively located on opposite surfaces of the two adjacent pillars 11, and the pillars 11 are provided with a hole plate 113 having a hole 1131 in the inner wall of the inner space 111, the hole The plate 113 is directed to the through hole 112, and the vacuum noise suppression device 10 of the casing 7 disposed on the adjacent surfaces of the respective sides is provided. A reinforcing member 5 is disposed between the two sides of the reinforcing member 5, and the reinforcing members 5 are respectively connected to the pillars 11 of the two adjacent vacuum type noise suppression devices 10. Further, one of the plurality of pillars 11 of the frame group 1 is provided with a partition 14 in the internal space 111, and an air suction valve 15 is disposed on the partition plate 14, and the air suction valve 15 is connected to the inside. Space 111.

Referring to the third to eighth figures, after the pillars 11 of the frame group 1 are set, the main feature of the present invention is that a plurality of support rods 4 are taken, and one end of each support rod 4 is welded in a spaced arrangement.
