Description

Double-layer wall

Technical Field

The utility model relates to the field of buildings, in particular to a double-layer wall.

Background

Double walls are layered walls with a cavity inside. Both theory and practice have shown that the sound insulation can be improved by 10dB or more, although the density is not changed when the single-layer wall is made into a divided double-layer wall. But the increase in the amount of sound insulation is slight for very low frequency sounds. In addition, in order to make the double-wall play its advantage, a porous sound-absorbing material should be added in the separated cavity between the two walls to suppress the cavity resonance that may occur. It is of interest to engineering practice that one of the layers of double wall can be made of light board (such as corrugated cardboard) with little increase in weight, but the sound insulation improvement provided by the cavity is still present.

However, the existing double-layer wall is inconvenient to construct, influences the use and brings inconvenience to people.
