Simple Prefabricated House Design Specifications

Currently, there is no unified national standard for the design specifications of simple prefabricated houses, but they generally need to adhere to the following norms and requirements:

Structural Safety Standards

The main structure of a simple prefabricated house must comply with safety standards. Building materials should possess sufficient strength and stability to withstand expected loads, including the house's own weight, wind loads, snow loads, etc. During the design process, full consideration should be given to local climatic conditions and geological characteristics. For example, in windy areas, the structure's wind resistance should be enhanced, and in areas with soft soil, the foundation's stability should be ensured to maintain structural stability under various environmental conditions.

Building Material Requirements

The building materials used should have good durability and fire resistance to reduce safety risks. Construction materials such as panels and metal frames should undergo quality certification and comply with relevant industry standards. For instance, color-coated steel sheets should have an appropriate fire rating to delay the spread of fire in case of a fire incident.

Plumbing and Electrical Engineering Standards

The plumbing and electrical facilities inside simple houses should be designed and installed in accordance with relevant national standards. Electrical wires and cables must use materials that meet safety standards and be laid correctly to avoid issues such as wire aging and short circuits that could trigger electrical fires. The water supply and drainage systems should be reasonably planned to ensure normal water supply and smooth drainage while complying with hygiene standards to safeguard the health of occupants.

Fire Protection Engineering Standards

Qualified fire protection facilities, such as fire extinguishers and smoke detectors, should be installed in the building and regularly inspected and maintained to ensure they function properly in emergencies. Additionally, the layout and design of simple houses should facilitate rapid evacuation of personnel in emergencies, such as by providing sufficient width and number of evacuation routes.

Other Requirements

Simple houses have relatively simple structures, with frames typically made of light steel or aluminum alloy and walls and roofs using lightweight panels such as color-coated steel sheets and plastic sheets. They usually have no foundation or only a simple foundation. If temporary construction is carried out within urban or town planning areas, approval from the urban or county people's government's urban and rural planning authorities is required, and the temporary construction should be self-demolished within the approved usage period. As a type of simple prefabricated house, prefabricated rural houses should also adhere to the principles of modern functionality, structural safety, cost-effectiveness, environmental friendliness, and harmonious appearance, and be designed and constructed in combination with local actual conditions.
