Prefabricated House Thickness Requirements Standard

The thickness requirements standards for prefabricated houses vary depending on the component type and application scenario, as detailed below:

I. Thickness Standards for Prefabricated Walls The thickness specifications of prefabricated walls are mainly divided into two types: 120mm and 150mm. Among them, 120mm-thick prefabricated panels are mostly used in light-load scenarios, such as internal partition walls or decorative walls, which have lower requirements for structural strength but need to meet basic functions such as sound insulation and fire prevention. The 150mm-thick prefabricated panels are suitable for structures that need to bear larger loads, such as exterior walls or floor slabs, and their thickness can provide higher structural stability and load-bearing capacity. In special buildings, the floor slab thickness of high-rise residential buildings may reach 180mm to 240mm, while for super high-rise buildings, due to the need to cope with larger loads and complex mechanical environments, the floor slab thickness may even need to be increased to 300mm to ensure building safety.

II. Thickness Standards for Prefabricated Floor Slabs The thickness of prefabricated floor slabs varies according to the material type and span requirements:

1. Ordinary Cement Prefabricated Floor Slabs: The thickness ranges from 60mm to 120mm, with the specific value directly related to the span. For example, for a floor slab with a span of 3 meters, the recommended thickness is 80mm to 100mm. The larger the span, the thicker the slab needs to be to avoid deformation or fracture.
2. Steel-Frame Lightweight Prefabricated Panels: The thickness ranges from 80mm to 150mm. The internal steel-frame structure enhances the overall strength and is suitable for scenarios that require both self-weight and load-bearing capacity.
3. Steel Truss Prefabricated Floor Slabs: The thickness ranges from 100mm to 300mm. The addition of steel trusses significantly enhances the flexural resistance of the floor slabs and is commonly used in large-span or high-load buildings, such as commercial complexes or industrial plants.

III. Other Special Requirements Some prefabricated houses have uniform standards for wall thickness. For example, the wall thickness of prefabricated cement houses is usually fixed at 15 centimeters (150mm), while allowing the floor height to be customized between 3 meters and 3.6 meters according to needs to adapt to different functional spaces.

Summary: The thickness design of prefabricated houses needs to comprehensively consider material characteristics, load requirements, and usage scenarios. Reasonable selection of thickness specifications is the key to ensuring building safety and functionality.
