Noise-reducing insulation fireproof wall

Abstract

The invention relates to a noise-reducing insulation fireproof wall comprising a stainless steel support. Gaps of the stainless steel support are filled with insulation material. A layer of acoustic absorbing material and a layer of soundproof material cover two sides of the stainless steel support which is meshed, respectively. A glass magnesium board covers the outer side of the layer of acoustic absorbing material. The outer side of the layer of soundproof layer is coated with a layer of sulphoaluminate quick-setting high-strength cement. The noise-reducing insulation fireproof wall has the advantages of good sound proofing effect, high acoustical absorption coefficient, good thermal insulating and fire proofing effects, convenience of manufacture, simplicity of construction, long service life and the like.

Description

technical field [0001] The invention belongs to the field of construction engineering, in particular to a noise reduction and heat preservation firewall. Background technique [0002] In industrial construction, civil construction, etc., the importance of walls is self-evident. While the wall meets the main functions of load-bearing and division, other aspects of performance cannot be ignored, such as earthquake resistance, heat preservation, fire prevention, etc. [0003] At present, the construction industry generally uses building materials such as clay bricks, cement bricks, and ceramsite concrete blocks for filling as interior and exterior wall materials. Due to their heavy weight, these building materials are inconvenient for construction, and have poor sound insulation, heat insulation and thermal insulation performance. The materials applied on the inner and outer sides of the wall are cement mortar or lime sand, which will cause cracks in the wall, and in severe c...

AI Technical Summary

Problems solved by technology

Due to their heavy weight, these building materials are inconvenient for construction, and have poor sound insulation, heat insulation and thermal insulation performance.

The material applied on the inner and outer sides of the wall is cement sand slurry or lime sand slurry, which will cause cracks on the wall surface, and in severe cases, the wall surface will fall off. This kind of wall surface material also has the disadvantages of poor heat insulation and thermal insulation performance.
