[0001] This utility model belongs to the field of ultra-low energy consumption sound insulation, sound absorption, heat insulation and thermal insulation modular composite shear wall system, specifically involving an ultra-low energy consumption sound insulation, sound absorption, heat insulation and thermal insulation steel mesh reinforced modular composite shear wall system. Background Technology

[0002] Current shear wall construction techniques all use double-sided formwork (inner and outer formwork) for support and reinforcement. After the concrete has reached its strength, the inner and outer formwork and support system are removed, and insulation construction is carried out subsequently. This wastes resources and does not meet the current requirements for energy conservation, environmental protection, green and low-carbon construction. Moreover, the secondary construction has a long construction period and high costs. To address this, we propose an ultra-low energy consumption sound insulation, sound absorption, heat insulation and steel mesh reinforced modular composite shear wall system.
