Can a Single-Story House Have Prefabricated Panels?

Single-story houses can use prefabricated panels. Prefabricated panels are building components that are prefabricated in a factory and then transported to the construction site for installation. Under specific circumstances, using prefabricated panels for single-story houses is feasible. The following provides an introduction from two aspects: applicable scenarios and key considerations.

Applicable Scenarios

• Temporary Buildings: For some temporarily constructed single-story houses, such as temporary dormitories on construction sites and temporary warehouses, using prefabricated panels enables rapid construction to meet short-term usage needs. Since prefabricated panels are made in the factory, on-site installation is convenient, which can significantly shorten the construction period and reduce time costs.
• Limited Budget Situations: The production of prefabricated panels can be carried out on a large scale, resulting in relatively low costs. For single-story house construction with a limited budget, such as when economically disadvantaged families in rural areas build small bungalows, choosing prefabricated panels can effectively control construction costs while ensuring a certain level of structural performance.
• Areas with Poor Geological Conditions: In areas with poor geological conditions, such as soft soil foundations, prefabricated panels are relatively light, exerting less pressure on the foundation. This can to some extent reduce the workload and cost of foundation treatment and lower the risk of house settlement caused by foundation problems.

Key Considerations

• Load-Bearing Limitations: Prefabricated panels have clear load-bearing limitations, with the load-bearing capacity of a single panel generally not exceeding 200 kg/㎡. When designing a single-story house, it is necessary to reasonably plan the usage functions and load distribution of the house to avoid concentrating overly heavy items on the prefabricated panels, which could exceed their load-bearing capacity, cause the panels to crack or even break, and affect the structural safety of the house.
• Joint Treatment: The treatment of joints between prefabricated panels is crucial. The joints should be filled with C20 fine aggregate concrete to ensure tight and firm connections, preventing rainwater leakage and air infiltration, and improving the waterproofing and thermal insulation performance of the house. At the same time, good joint treatment can also enhance the overall integrity of the prefabricated panels and improve the structural stability of the house.
• Seismic Performance: In areas with a seismic fortification intensity of 7 degrees or above, the seismic performance of prefabricated panels is relatively weak and requires reinforcement. This can be achieved by adding seismic structural measures such as structural columns and ring beams to improve the overall seismic capacity of the house and ensure its safety in the event of an earthquake.
