Prefabricated Super-High Building Finished Product

Prefabricated super-high building finished products typically adopt a modular construction approach, achieving efficient construction through a combination of factory prefabrication and on-site assembly.

Construction Methods and Typical Cases

The core of modular construction is to break down the building into independent modules. After completing processes such as wall, floor, plumbing, electrical, and decoration work in the factory, these modules are transported to the construction site for assembly. For example, a public housing project in Shenzhen, Guangdong, assembled five residential buildings nearly 100 meters high using 6,028 concrete modules, with over 2,000 households already moved in. The Anju Jingxin Yuan project took only 148 days from the first module hoisting to the completion of the 30th floor's fine decoration. This model significantly shortens the on-site construction period. For a 16-story building, for instance, it takes only 120 days from the first module hoisting to readiness for delivery, a 60% reduction compared to traditional construction timelines.

Core Advantages

1. Short Construction Period: Factory prefabrication and on-site assembly operate in parallel, reducing interference from weather and labor factors. For example, a project in Shenzhen compressed the construction period of high-rise buildings to 40% of traditional methods using modular technology.
2. Controllable Quality: Standardized production in a factory environment ensures millimeter-level precision in wall flatness, piping layout, and other aspects. Each module comes with an 'ID card' (including project name, model, production date, etc.) for easy quality traceability.
3. Energy Efficiency and Environmental Protection: Centralized factory production reduces material waste, while on-site assembly lowers dust and noise pollution. Modular structures use insulation and energy-saving materials to enhance building energy efficiency.
4. Strong Safety Performance: Modules are connected with high-strength bolts and combined with concrete or steel frames, offering earthquake and pressure resistance, fire and flame retardancy, wind and moisture resistance, and corrosion and weathering resistance, adapting to complex environmental needs.

Technical Characteristics

Modular construction ensures tight assembly through 'millimeter-level' precision control, avoiding error accumulation seen in traditional construction. For example, a 16-story building in Shenzhen achieved overall structural stability through the precise对接 (docking/connection) of 298 modules. Additionally, modular design supports flexible expansion, allowing adjustments in floor numbers or functional zoning based on needs, enhancing building adaptability.

In conclusion, prefabricated super-high building finished products have realized an efficient, precise, and sustainable construction model through modular technology, becoming an important development direction for modern high-rise buildings.
