Detailed Description
In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention clearer and more obvious, the following description is made in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 3, the present embodiment includes a hollow brick wall skeleton, a shell aggregate layer 2 and a porous material layer 3.
The hollow brick wall skeleton is formed by overlapping hollow bricks 1 in staggered joints and building the hollow bricks by using a bonding material; the binding material adopts cement mortar; the staggered joint of the hollow bricks 1 can meet the mechanical performance indexes of wall surface such as load bearing and the like.
The shell aggregate layer 2 is provided with two layers, the two layers are respectively filled in the front side and the rear side of the cavity of the hollow brick 1, the shell aggregate is suitable for various shells and shells with different dimensions, and in the embodiment, the size of the shell aggregate is 20-150 mm, preferably 50 mm.
The porous material layer 3 is arranged between the two shell aggregate layers 2 and comprises glass wool, rock wool, mineral wool and the like; the thickness of the porous material layer 3 is 30-100 mm, preferably 50 mm. The porous material is beneficial to adjusting and improving the sound absorption spectrum characteristic of the double-sided shell aggregate sound absorption wall surface structure.
The utility model discloses can rely on the hollow brick of current different specifications, as long as the hollow brick can provide the cavity of filling the shell aggregate and can adopt, be suitable for batch production. The shell aggregate is filled without any mortar, and the sound absorption interface system is formed by filling the shell aggregate by a dry-masonry process according to the principle that the maximum gap is formed and the shell aggregate can be tightly connected.
