Two-Story Prefabricated Concrete House
The two-story prefabricated concrete house is a building form that utilizes factory-prefabricated components for rapid on-site assembly, characterized by efficient construction, excellent performance, and controllable costs.
Construction Features
The core construction process of the two-story prefabricated concrete house involves 'factory prefabrication + on-site assembly.' Major components such as load-bearing columns and beams are pre-made in the factory using standardized molds to ensure dimensional accuracy. During on-site construction, workers direct cranes to precisely assemble multi-ton prefabricated components, using protrusions and recesses in a mortise-and-tenon structure for initial positioning, followed by fastening with nuts. The second-floor frame can be assembled within half a day, after which a 5-centimeter-thick prefabricated floor slab is laid, and all gaps are sealed with expanding foam to enhance airtightness. Secondary grouting is required at the connections of load-bearing columns, followed by covering with steel mesh and pouring concrete to form a rigid connection throughout the structure, enhancing seismic performance.
Pricing Information
Prices vary by brand and region. For example, the product price quoted by Shandong Jining Xiangyun Prefabricated Building Co., Ltd. is 1280 yuan per square meter, while Hebei Langfang Hebei Zhongzhu Housing Technology Co., Ltd. quotes 1000 yuan per square meter. Actual costs may be influenced by factors such as component materials, design complexity, and transportation distance, requiring negotiation with suppliers based on specific needs.
Product Advantages
- Excellent Performance: The structure adopts a reinforced concrete composite system, offering multiple properties such as seismic and compressive resistance, fire and flame retardancy, thermal insulation and energy efficiency, wind and moisture resistance, and corrosion and weathering resistance, adaptable to various climatic conditions.
- Efficient Construction: The factory prefabrication and on-site assembly model significantly shortens the construction period and is not limited by seasons or weather, allowing for year-round construction.
- Long Service Life: Designed for a lifespan of over 70 years, it requires simple maintenance and has low long-term usage costs.
- Reusability: Components support overall relocation or secondary disassembly and assembly, with recycling significantly reducing investment costs.
Scope of Application
This building form is suitable for scenarios such as office buildings, small hotels, staff dormitories, canteens and restaurants, private garages, and storage warehouses. It is particularly well-suited for needs such as rural dilapidated house renovations, rural self-built housing, farm ancillary buildings, temporary office and accommodation buildings on construction sites, and temporary engineering support buildings, balancing functionality and economy.
