The top of the support rod 21 is fixedly welded to the insertion block 22; the sound insulation layer assembly 4 includes a first sound insulation plate 41, a second sound insulation plate 42 and an insertion block 43. The outer end faces of the first sound insulation plate 41 and the second sound insulation plate 42 are respectively provided with protruding locking rods 403, which penetrate through the interior of the sound absorption layer plate 5. The inner end faces of the first sound insulation plate 41 and the second sound insulation plate 42 are respectively fixedly connected to the insertion block 43, which is inserted into the interior of the insertion block 22 and the insertion block 301 with corresponding heights.

[0031] As attached Figure 4 As shown, the sound-absorbing layer 5 has sound-absorbing holes 501 inside, and the sound-absorbing holes 501 are penetrated by protruding clips 403. The sound-absorbing layer 5 is made of polyester fiber sound-absorbing board. After the sound insulation layer assembly 4 and the support structure rod assembly 2 are installed inside the outer connecting frame 3, the sound-absorbing layer 5 is finally bonded by sealing the perimeter with cement. Alternatively, it can be bonded by using high-strength sealant in conjunction with nailing. The choice can be made flexibly according to the environmental protection requirements of construction.

[0032] As attached Figure 1 As shown, an adhesive layer 101 is laid on the exterior surface of the base wall 1. The adhesive layer 101 is made of cement mortar. Under the same conditions, the adhesive layer 101 can be laid with a high-adhesion adhesive, which can also meet the bonding effect.
