Rural Prefabricated Slab House Design
The design of rural prefabricated slab houses requires comprehensive consideration from multiple aspects such as structural safety, spatial layout, waterproofing and moisture resistance, detailed decoration, and the placement direction of prefabricated slabs to ensure that the houses are both practical and safe.

Structural Design and Safety
Prefabricated slabs have limited load-bearing capacity, so their limitations must be clearly defined during design to avoid overloading. For two-story and half-story structures, additional beams and columns should be added to enhance overall stability. In rural areas of Sichuan with different seismic fortification intensities, for areas with a seismic fortification intensity of six degrees, prefabricated slabs can be used for small spans below two stories, but reinforced concrete ring beams must be provided; for areas with a seismic fortification intensity of seven degrees or above, it is recommended to directly use cast-in-place slabs. The room span directly affects the choice of slab type: For ordinary bedrooms with a span of less than 3.6 meters, prefabricated slabs can be used, but cast-in-place slabs are more stable; for living rooms and master bedrooms with a span of 3.6 to 4.8 meters, it is recommended to use cast-in-place slabs or thickened prefabricated slabs with structural reinforcement; for large-span living rooms with a span of more than 4.8 meters, cast-in-place slabs must be used as prefabricated slabs cannot meet the deflection requirements.
Spatial Layout and Functional Division
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, kitchen, and bathroom, while the second floor and half-story can be set up as bedrooms, a study, and a small leisure area to meet the needs of living, storage, and leisure. The position of the stairs needs to be reasonably laid out to avoid occupying too much space or affecting the use of other functional areas, while ensuring convenient access up and down the stairs.
Waterproofing and Moisture Resistance Treatment
Prefabricated slab structures have high requirements for waterproofing and moisture resistance. For damp areas such as bathrooms, waterproof coatings or waterproof membranes should be used to ensure that the floors and walls do not leak water. Overall moisture resistance can be achieved by laying a moisture-proof layer and using building materials with good air permeability to reduce indoor moisture problems and extend the service life of the house.
Detailed Design and Decoration
Lighting and ventilation are crucial, so the positions and sizes of windows need to be reasonably designed to ensure sufficient indoor light and air circulation. The decoration style should be mainly simple, avoiding too many complex shapes and decorations to reduce the structural load and keep the space neat and beautiful.
Placement Direction of Prefabricated Slabs
When covering the floor slabs, they should be horizontally built in the direction with a smaller span. Horizontal floor slabs can withstand more pressure, and when the foundation settles, floor slabs with a smaller span are more stable and have higher safety.
