Shandong Prefabricated House Design Plan
The design plan for prefabricated houses in Shandong needs to comprehensively consider multiple factors, with the following key points:
General Requirements and Building Scale The design plan should align with the regional characteristics, living customs, and production needs of rural areas, ensuring complete functionality, reasonable layout, and meeting requirements for sunlight, ventilation, and lighting. The building area of houses is divided into three categories: basic type (50㎡ - 90㎡), improved type (120㎡ - 180㎡), and upgraded type (> 200㎡). The area of the homestead should be determined based on local conditions.
Structural Safety and Material Selection The structure should meet requirements for earthquake resistance (with a seismic fortification intensity of no less than 7 degrees), fire prevention, and disaster prevention. It is recommended to adopt structural systems such as prefabricated concrete shear walls, EPS module cast-in-place concrete, and light steel frames. In Jinan, high-strength cold-formed thin-walled steel frames combined with rock wool or polyurethane sandwich panels are commonly used, which offer thermal insulation, fire prevention, and sound insulation properties. The foundation uses prefabricated concrete strip foundations or screw steel piles, along with adjustable brackets to prevent uneven settlement.
Age-Friendly and Barrier-Free Design The floors should be slip-resistant, and the bathrooms should have provisions for installing handrails to promote the installation of flush toilets indoors. Barrier-free ramps should be set up at entrances and exits to meet the needs of the elderly and those with mobility impairments.
Architectural Style and Energy Efficiency Requirements The architectural style should reflect the regional characteristics of central Shandong, northwest Shandong, southwest Shandong, and the Jiaodong Peninsula, harmonizing with the surrounding environment and emphasizing the inheritance of traditional culture. The promotion of green building materials and the application of new energy sources, such as solar thermal and photovoltaic systems, is encouraged. Priority should be given to using local economical materials, and the use of high-energy-consuming and polluting materials that exceed standards is prohibited.
Construction and Cost Control The cost should be controlled at around 1,400 yuan per square meter, based on local sourcing and recycling. Construction should be carried out by professional teams or trained rural craftsmen, and a detailed construction plan should be formulated. The modular quick-assembly houses in Jinan use double-sided color-coated steel sandwich rock wool panel walls, with waterproof tape and metal pressure strips covering the panel seams and expansion joints reserved. The roof has a three-layer waterproof structure with a slope greater than 15 degrees. The interior is equipped with a moisture-proof elevated floor, the walls are finished with water-resistant putty and latex paint, and the baseboards are designed with stainless steel mold resistance. Some projects integrate intelligent ventilation, lighting, and fire protection systems to improve operational efficiency.
