It is prominent to have fireproof function concurrently simultaneously.
The utility model is further arranged to：Described Constrained Plates include damping layer, carbon fiber restraint layer.
By using above-mentioned technical proposal, Constrained Plates when being under pressure, carbon fiber restraint layer and wall it
Between produce Relative sliding, carbon fiber self-strength is higher to reduce the situation that Constrained Plates stress is broken, while damping layer
The deformation that Constrained Plates compression is produced can be reduced, is conducive to the structural integrity of Constrained Plates.
The utility model is further arranged to：Be provided with fireprotection layer on the outside of described Constrained Plates, the fireprotection layer with about
Screed-coat is provided between beam damping sheet.
By using above-mentioned technical proposal, wall has good fire protecting performance during use, reduces absorbent treatment
It is heated or is influenceed by fire, screed-coat is conducive to wall integrally-built smooth.
The utility model is further arranged to：Described fireprotection layer is light fire-proof wallboard.
By using above-mentioned technical proposal, light fire-proof wallboard is while ensure that wall fire resistance property to whole face wall body
Thickness effect it is smaller.
In summary, the utility model has the advantages that：
1st, the sound absorption performance of wall is enhanced；
2nd, the fire protecting performance of wall is also ensure that while sound absorption performance is reached.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment：A kind of sound absorption damping-constraining wall body structure, as shown in figure 1, including wall 1, noise is in diffusive transport
During in order to reduce the amount that noise passes through wall 1, the effect of the sound absorption of wall 1 can be improved through wall 1；In wall 1
Keel 2 are provided with, keel 2 are realized by steel nail 3 and wall 1 and fixed, while being provided with Constrained Plates 4, keel in the outside of keel 2
2 is provide effective support between Constrained Plates 4 and wall 1, in order to reach the effect of sound absorption, in constraint resistance
Absorbent treatment 5 is provided between Buddhist nun's plate 4 and wall 1, increased absorbent treatment 5 has certain sound absorption to noise on the surface of wall 1
Effect, the effective noise that reduces is propagated through wall 1, realizes the effect of sound insulation and noise reducing, Constrained Plates 4 by keel 2 and
Wall 1 realizes connection, effectively reduces the situation that absorbent treatment 5 drops from wall 1, is conducive to the sound absorption effect of wall 1.
When there is external force to be applied in Constrained Plates 4, Constrained Plates 4 can produce certain pressure, meeting to absorbent treatment 5
The phenomenon for causing the structure of absorbent treatment 5 to be damaged, in order to reduce influence of the Constrained Plates 4 to absorbent treatment 5, on wall 1
Some elastomeric support columns 6 are uniformly fixed with, elastomeric support column 6 is contradicted through absorbent treatment 5 with Constrained Plates 4, elastomeric support column 6
