Prefabricated Concrete Integrated House

Prefabricated concrete integrated house is a new type of construction method that adopts factory production and modular assembly, featuring high efficiency, cost-effectiveness, reliability, and environmental friendliness, suitable for various scenarios.

Technical Principles

The full name of the prefabricated concrete integrated house is "prefabricated reinforced concrete full-frame shear wall structure house," with the core process being factory prefabrication and on-site assembly. At specialized production bases, core components such as walls, floors, beams, and columns are cast in one piece using high-precision molds. Each module integrates multiple structures, including steel reinforcement skeletons, insulation layers, waterproof layers, and pre-embedded pipelines, allowing for flexible combination into a complete building.

Core Advantages

1. High Efficiency: Core components are produced in factories and assembled on-site through hoisting, significantly shortening the construction period. For example, the main structure of a 200㎡ villa can be hoisted and completed in 4 hours, saving 90% of the time compared to traditional construction. A single 30㎡ module can be prefabricated in the factory in just 7 days, and three workers on-site can complete the installation of a single module in 4 hours with the assistance of a crane, with the entire 100㎡ house taking only 2 days to build.
2. Low Cost: Compared to traditional construction methods, costs are reduced by approximately 30%. For example, the main structure of a 100㎡ house can be built for 100,000-120,000 yuan, which is 30% cheaper than a brick-and-mortar structure. For a 120㎡ rural self-built house, the traditional brick-and-mortar construction cost is approximately 180,000-220,000 yuan (including labor), while the cost of the main modules of a concrete house is only 120,000-150,000 yuan, with the total cost, including interior and exterior decoration, controlled within 200,000 yuan.
3. Reliable Quality: C30-C40 grade concrete is used, with built-in Φ8-Φ12 steel reinforcement meshes, achieving a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. Modules are connected through prestressed bolts and welded steel plates to form an overall frame, with a wind resistance rating of up to Level 10 and a seismic fortification intensity of Level 7 (equivalent to the destructive force of the Wenchuan earthquake), and have been tested to withstand typhoons of up to Level 12.
4. Green and Environmentally Friendly: The factory production process achieves a 95% recycling rate of offcuts, with no dust or sewage discharge on-site, and construction waste accounting for only 10% of that from traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, far below the national standard (0.1mg/m³), enabling "immediate occupancy" upon completion.
5. Thermal Insulation and Energy Efficiency: The walls are designed with reserved slots for EPS insulation layers, which, when inserted on-site, improve thermal insulation performance by 40%, providing significant warmth in winter and coolness in summer, and reducing winter heating costs by half.

Application Scenarios

Suitable for rural self-built houses, commercial spaces, cultural and tourism projects, etc. For example, the Moganshan area has used them to build homestays, increasing annual income by threefold.

Precautions

1. Design Limitations: The design is relatively fixed, and personalized modifications require additional customization fees.
2. Brand Selection: It is essential to choose reputable and qualified brands to ensure quality and after-sales service.
