Prefabricated House Production Cases
Prefabricated house production cases include the Guangdong Shenzhen affordable housing project, the VDC (vale de cambra) project, and the prefabricated assembled light-steel house project.
Guangdong Shenzhen Affordable Housing Project: This project employs concrete module assembly technology, with five residential buildings nearly 100 meters high assembled from 6,028 concrete modules. Taking a two-bedroom unit of 70 square meters as an example, it can be assembled with just two and a half modules. Compared to traditional construction methods, this project excels in terms of construction duration, labor usage, and environmental protection. The completion and delivery time has been shortened from the traditional 2.5 to 3 years to just 1 year, and on-site labor usage has been reduced by approximately 50%. Additionally, since most construction processes are completed in the factory, noise, dust, construction waste, and traffic congestion at the construction site are significantly reduced, minimizing disturbances to the surrounding community.
VDC (vale de cambra) Project: Portuguese construction company SUMMARY utilized the 'Gomos system' to build this 10,743-square-foot mixed-use development project in the Serra da Estrela mountains. The project features a floating desk covering a multi-service open space and includes six tubular housing units. This innovative design not only demonstrates the flexibility of prefabricated houses but also showcases their adaptability in complex terrain conditions.
Prefabricated Assembled Light-Steel House Project: These houses use light-steel frames as the load-bearing structure, with walls, floors, roof trusses, and other components prefabricated in the factory and then transported to the site for rapid assembly. Taking a 200-square-meter light-steel villa as an example, the main structure installation can typically be completed within 15 to 30 days. Its advantages are significant, including high dimensional accuracy from factory prefabrication, short construction periods (a 300-square-meter two-story villa can be completed from foundation to roof sealing in just 30 to 45 days, much shorter than the 3 to 6 months required for traditional brick-and-mortar structures), minimal climate impact, excellent thermal insulation (with a heat transfer coefficient as low as 0.3 to 0.5 W/(m²·K)), outstanding seismic performance (under a 7-degree seismic design intensity, the main structure typically only undergoes elastic deformation), flexible spatial layout, and environmental health (using dry construction methods, with 100% recyclable steel and mostly green building materials for interior and exterior walls).
