Advantages of Tongliang Cement Prefabricated Houses
The advantages of Tongliang cement prefabricated houses are mainly reflected in aspects such as short construction periods, effective cost control, significant energy conservation and environmental protection, strong structural stability and durability, excellent earthquake and wind resistance, and flexible adaptability.
Short Construction Period: The components of cement prefabricated houses are rapidly manufactured and assembled in factories, significantly reducing the overall construction time. For example, for buildings of the same size, the prefabrication method can shorten the construction period by 50%-70%. A single module (30㎡) takes only 7 days from rebar tying to concrete pouring, unaffected by weather conditions. A 100㎡ house (composed of three modules) can be fully installed in just 1 day, reducing the construction period by 90% compared to traditional methods.
Effective Cost Control: Factory production reduces labor costs, minimizes material waste, and shortens the construction period. The number of on-site construction personnel is reduced by 60%, the turnover frequency of formwork increases to over 50 times (compared to only 5-8 times for traditional wooden formwork), and the rental period for machinery is reduced by 40%. Although the cost per cubic meter of concrete is slightly higher, when considering hidden costs such as mold transportation, the overall lifecycle cost remains economically advantageous.
Significant Energy Conservation and Environmental Protection: Industrial production reduces on-site noise pollution and waste emissions, with construction waste reduced by 90%. Environmentally friendly concrete incorporating 30% waste materials is used. Its thermal insulation properties reduce energy consumption, aligning with the energy-saving and emission-reduction goals of sustainable development.
Strong Structural Stability and Durability: The components are of reliable quality, precise in size, and firmly connected, ensuring the stability of the building. For example, using C35 concrete for integral pouring, a single module weighs over 20 tons, forming a rigid structural system. Its earthquake resistance is 6.8 times that of brick-concrete structures, capable of withstanding magnitude 8 earthquakes. Its wind resistance meets the standard for typhoons of magnitude 12, with a roof waterproofing grade of II and a fire resistance limit of 3 hours.
Excellent Earthquake and Wind Resistance: Integral joint connection technology enhances earthquake resistance. The prefabricated concrete frame can withstand magnitude 8 earthquakes, with full hysteresis loops at joints and a 35% increase in energy dissipation capacity. The "full-frame shear wall" design can withstand magnitude 8 earthquakes (with a designed seismic fortification intensity of magnitude 7), controlling wall crack widths within 0.2mm and ensuring no damage to the main structure. Under magnitude 12 typhoons, the prestressed bolt connections between modules remain tight, and the roof waterproofing membrane is not at risk of being blown off.
Flexible Adaptability: Modular design supports horizontal splicing, vertical stacking, and functional conversion, meeting the diverse needs of scenarios such as homestays.
