Specifications for Thickness Requirements of Prefabricated Houses

Quản trị 18 tháng 9, 2026

The thickness requirements and specifications for prefabricated houses vary depending on the type of component and the usage scenario. Specific specifications are as follows:

I. Thickness Specifications for Prefabricated Panels The thickness of prefabricated panels should be selected based on load requirements:

  • Light-load scenarios: For internal partition walls or decorative walls, common thicknesses are 60-90mm (lightweight partition walls) or 120mm (ordinary partition walls).
  • Load-bearing structures: For floors or exterior walls that need to bear significant loads, the standard thickness is 150mm. Floors in high-rise residential buildings may increase to 180-240mm, and ultra-high-rise buildings may even require 300mm. The minimum requirement for load-bearing walls is 120mm.

II. Thickness Specifications for Prefabricated Floor Slabs The thickness of floor slabs is related to materials, spans, and purposes:

  • Ordinary cement prefabricated floor slabs: Thickness ranges from 60-120mm, with a recommended thickness of 80-100mm for spans of 3 meters.
  • Steel-framed lightweight prefabricated panels: Thickness ranges from 80-150mm, suitable for lightweight structures.
  • Steel truss prefabricated floor slabs: Thickness ranges from 100-300mm, often used for large spans or high-rise buildings.
  • Standard prefabricated floor slabs: Common thicknesses are 100mm, 120mm, 150mm, and 180mm, with some projects adopting 200mm and 250mm.
  • Non-standard prefabricated floor slabs: Thickness can be customized, ranging from 100-300mm.
  • Thin-panel prefabricated floor slabs: Thickness ranges from 50-80mm, suitable only for light steel structure houses or temporary buildings.

III. Thickness Specifications for Walls of Prefabricated Houses Wall thickness should consider insulation, load-bearing capacity, and space requirements:

  • 75mm walls: Primarily used for interior partitions to save space.
  • 90mm walls: Suitable for exterior wall insulation layers, balancing insulation and cost.
  • 100mm walls: Commonly used for exterior wall insulation and lightweight house construction.
  • 120mm walls: Used for heavy industrial buildings to meet higher load-bearing requirements.

IV. Thickness Specifications for Special Scenarios

  • Livestock manure leakage boards: Thickness ranges from 50-80mm, requiring a balance between strength and breathability.
  • Cable well cover plates: Fixed thickness of 50mm to ensure safety and durability.
  • Prefabricated houses in rural Henan: Wall panel thickness is approximately 120mm, but some users consider it too thin and require evaluation based on actual loads.

Summary: The selection of thickness for prefabricated houses should consider material properties, load requirements, and usage scenarios. Strictly adhering to relevant specifications ensures structural safety and functional realization.
