Shandong Prefabricated House Construction Plan

The construction plan for prefabricated houses in Shandong should be systematically designed by integrating normative requirements, structural systems, construction techniques, and regional characteristics. The specific implementation points are as follows:

1. Compilation Basis and Principles The construction plan must strictly adhere to national standards such as the Unified Standard for Construction Quality Acceptance of Building Engineering (GB50300-2013) and the Code for Acceptance of Construction Quality of Concrete Structures (GB50204-2015), while also referencing local construction regulations in Shandong Province. During the design phase, the principles of 'modern functionality, structural safety, cost-effectiveness, environmental friendliness, and harmonious aesthetics' should be implemented, taking into account local climate, topography, and traditional architectural features to ensure that the houses meet modern living needs while integrating with regional culture. For example, the layout of traditional courtyard houses can be referenced in central Shandong, while sloped roofs can be incorporated in southwestern Shandong to reflect local characteristics.

2. Structural Systems and Material Selection The structural system of prefabricated houses should be flexibly selected based on project requirements:

• Prefabricated Concrete Shear Wall Structure: Suitable for high-rise buildings or those with high seismic requirements, improving construction efficiency through on-site assembly of prefabricated wall panels;
• EPS Module Cast-in-Place Concrete Structure: Utilizes insulation modules as formwork to achieve integrated structure and insulation, reducing energy consumption;
• Lightweight Steel Frame Structure: Ideal for low-rise residential buildings, characterized by light weight and fast construction. Material selection should prioritize green, economical, and recyclable materials such as recycled concrete and bamboo, while prohibiting the use of high-energy-consuming or excessively polluting materials to ensure environmental friendliness.

3. Construction Techniques and Deployment The construction plan should specify the lifting process, quality standards, and safety measures for prefabricated components:

• Laminated Steel Mesh House Construction System: Simplifies the construction process and reduces reliance on complex terrain by using factory-prefabricated components, small transport vehicles, and on-site assembly;
• Guangming Jiulongtai Project Case: Adopts an internal pouring and external hanging process, with prefabricated exterior wall panels lifted and assembled, combined with BIM technology to optimize the lifting sequence and reduce errors;
• Shandong Zhongshu Jiayuan Practice: Addresses construction challenges in mountainous terrain by simplifying foundation treatment (e.g., using strip foundations) and modular transportation. Construction deployment should involve reasonable planning of transportation routes, selection of lifting equipment, and on-site stacking areas to ensure tight sequence衔接 (sequential connection) of processes.

4. Quality and Safety Management Develop specialized plans for component installation and node construction, clarifying quality acceptance standards (e.g., verticality deviation of components ≤ 3mm). Construction teams should possess professional qualifications or be trained and qualified, with technical personnel providing on-site guidance for key processes (e.g., node connections). Safety measures include setting up temporary supports, wearing safety protective equipment, and regularly inspecting lifting equipment to prevent risks such as falls from heights or component overturning.

5. Regional Characteristics and Aging-Friendly Design Architectural styles should reflect regional differences: seaweed house elements can be adopted in Jiaodong, while flat roofs and thick walls can be incorporated in northwestern Shandong to adapt to arid climates. Aging-friendly design should include barrier-free ramps, non-slip floors, and low-positioned switches to enhance living convenience for the elderly.
