Rapid Assembly Prefabricated Housing

Rapid assembly prefabricated housing is a construction mode that disassembles buildings into independent modules, prefabricates them in factories, and then transports them to the site for assembly.

Core Features

The construction process of prefabricated housing is highly industrialized. Its ceilings, floors, water and electricity pipelines, walls, and bathroom waterproof layers are all prefabricated on factory assembly lines. The modules are produced through standardized design. During on-site assembly, they are connected and fixed like building blocks using bolts, welding, or snap-fit methods. For example, the China State Construction Hailong Intelligent Construction Industrial Park in Shenzhen, Guangdong, adopts parallel operations, automated three-dimensional warehouses, and intelligent production lines, reducing the construction period by more than 60% compared to traditional buildings and delivering 20,000 to 30,000 modules annually.

Technical Advantages

1. Efficiency Improvement: Factory prefabrication and on-site construction are carried out simultaneously, significantly shortening the project duration. For instance, in a certain affordable housing project in Shenzhen, five nearly 100-meter residential buildings were assembled from 6,028 concrete modules. The completion and delivery time was reduced from 2.5 - 3 years to 1 year, and the on-site labor force was reduced by about 50%.
2. Quality Control: The factory environment is enclosed, so module production is less affected by the weather. Moreover, mechanized operations reduce human errors and ensure the accuracy of components.
3. Environmental Protection and Energy Conservation: On-site operations reduce noise, dust, and construction waste by more than 60%, alleviating traffic congestion. In a reinforced concrete prefabricated housing project in Henan, it takes only 4 hours to hoist and assemble a set of houses, and the material loss rate is lower than that of traditional construction.
4. Cost Optimization: The E - MIC prefabricated concrete box-type housing system reduces module usage by 30% - 40% through the spaced arrangement of module units, increasing the usable floor area ratio and reducing material costs. The cost per square meter of prefabricated housing in Henan is about 300 yuan, with a lifespan of 70 years.

Application Scenarios

Prefabricated housing is suitable for various construction needs:

• Residential Sector: The affordable housing project in Shenzhen adopts a modular design. A 70-square-meter unit is assembled from two half-modules, flexibly meeting residential requirements.
• Urban Renewal: The E - MIC system can be flexibly arranged in space, making it suitable for the renovation of old residential areas or the construction of new residential buildings.
• Public Buildings: Prefabricated housing in Henan can be used as dormitories and office buildings, with a maximum height of 5 floors, covering low-rise to medium- and high-rise scenarios.
• Emergency Construction: Modular housing can be quickly assembled and is suitable for post-disaster reconstruction or temporary medical facilities.

Typical Cases

• Shenzhen China State Construction Hailong Industrial Park: Through intelligent production, it achieves an annual module delivery volume of 20,000 - 30,000 and reduces the construction period by 60%.
• Reinforced Concrete Prefabricated Housing in Henan: Assembled based on homesteads, it has high hoisting efficiency, low cost, and wide applicability.
• Shanghai Real Estate Project: Tower cranes transport prefabricated modules with 'identity cards' to achieve precise installation and full life-cycle management.
