Abstract

The 3D printing sound insulation curtain wall comprises a bottom plate, a middle layer and a surface layer, a plurality of sound insulation holes are formed in one side of the bottom plate, the surface layer is arranged on the other side of the bottom plate, and the cross sectional area of the ends, away from the surface layer, of the sound insulation holes is smaller than that of the other ends of the sound insulation holes; a sealed cavity is formed between the bottom plate and the surface layer, and the middle layer is arranged in the cavity; the surface layer and the bottom plate are formed by bonding powder materials through a binder, and the middle layer is formed by filling the powder materials. The 3D printing sound insulation curtain wall disclosed by the invention has a good sound insulation effect, three layers are integrally printed and formed, and the structural design is ingenious; by means of block printing and assembling, the curtain wall is suitable for various sizes and complex structures which cannot be manufactured through a conventional method, and meanwhile the requirements for sound insulation, environmental protection and decoration of curtain walls for decoration can be met.

Description

technical field [0001] The invention relates to the technical field of soundproof curtain walls, in particular to a 3D printed soundproof curtain wall and a manufacturing method thereof. Background technique [0002] In traditional house decoration, the sound insulation effect is to attenuate sound waves by fixing a layer of porous plates with sponge behind on the wall. The principle of this kind of porous plates to reduce sound waves is porous sound absorption and resonance sound absorption. This results in a larger surface area to absorb sound waves. Resonance sound absorption is Helmholtz resonance, that is, the external space and the internal space are connected by a narrow bottleneck. When the sound wave is incident, a severe resonance effect occurs between the air and the internal space of the neck at the resonance frequency and the sound energy is lost. This kind of perforated board is made of two materials and then bonded together. The production process is complica...
