Layout of Rural Prefabricated Slab Houses

The layout of rural prefabricated slab houses should comprehensively consider structural safety, functional requirements, and construction specifications. The specific design points are as follows:

1. Structural Safety and Span Direction

The laying direction of prefabricated slabs directly affects the earthquake resistance and load-bearing capacity of the house. Rural houses are usually wider than they are long, and the north-south span of small internal rooms often exceeds the east-west span. Therefore, prefabricated slabs should be laid horizontally in the direction of the smaller span (e.g., east-west) to disperse pressure and enhance earthquake resistance. If the room span is extremely small (e.g., 2 meters long and 3 meters wide), the laying direction has a relatively minor impact on the structure and can be adjusted flexibly. Additionally, the quality of prefabricated slabs must meet national standards, and quality inspections should be carried out after construction to ensure that load-bearing capacity and durability meet the requirements.

2. Functional Zoning and Space Design

• Typical Layout: Taking a 60-square-meter two-and-a-half-story small building as an example, the first floor can be planned as a living room, a sitting room, a kitchen, a dining room, and a bedroom suite; the second-floor layout is similar to that of the first floor, with a suite on the east side and the rest as bedrooms, accommodating both living and activity needs.
• Kitchen and Bathroom Treatment: Due to the high waterproofing requirements in kitchens and bathrooms, it is recommended to use cast-in-place slabs instead of prefabricated slabs and construct them according to the waterproofing standards of high-rise buildings to avoid leakage problems.
• Partition Walls and Piping: If 12-inch walls (thin walls) are used, slots need to be cut to embed electrical wiring pipes. However, the depth of the slots must be strictly controlled to avoid damaging the structural stability of the walls.

3. Electrical and Lightning Protection Systems

• Electrical Embedding: During the wall-building stage, pipes and boxes for switches, sockets, and distribution boxes need to be embedded. The height of the boxes should be 2 millimeters above the wall surface; pipes for lighting fixtures need to bypass within the ring beams and be embedded from the seams of the prefabricated slabs to the designated positions to ensure circuit safety.
• Lightning Protection Measures: Rural areas are open environments with a high risk of lightning strikes, so it is recommended to install a lightning protection system. The grounding electrode should be made of galvanized steel pipes driven into the ground and connected to the column reinforcement. The roof lightning protection should follow the standards of high-rise buildings to reduce the risk of lightning strikes.

4. Decoration and Style Limitations

Due to the structural limitations of prefabricated slabs, interior decoration should mainly adopt a simple style, avoiding complex shapes or heavy decorative materials to reduce the structural load. For example, light-colored paints or wallpapers can be used for walls, and the ceiling design should be simplified to ensure overall safety.

5. Construction Specifications and Inspections

The construction process must strictly adhere to specifications, including the installation of prefabricated slabs, the embedding of pipes, and waterproofing treatment. After completion, quality inspections and electrical safety tests should be carried out to ensure that the house meets living standards and guarantees long-term safety in use.
