Mobile Cement Prefabricated Housing Structure

The mobile cement prefabricated housing structure mainly includes three types: flat-panel type, box type, and row house type (combined villa), each with distinct structural design and material characteristics.

I. Structural Types Classified by Function

1. Flat-Panel Type: Focused on simplicity and practicality, it adopts a single-layer flat-panel structure with modules quickly connected via bolts or welding. Its advantages include convenient transportation (stackable to reduce space occupation), high assembly efficiency (usually completing basic construction in a few hours), and suitability for temporary residences and commercial rentals. Structurally, it primarily uses reinforced concrete with relatively thin walls, meeting basic living needs through optimized layouts, offering low costs and reusable disassembly and assembly.
2. Box Type: Drawing on the standardized design of containers, it features a closed rectangular structure with high-strength connection nodes at the corners. It is characterized by strong sealing (withstanding wind, rain, and sand), excellent thermal insulation (walls filled with rock wool or polystyrene boards), and internal spaces divisible into functional areas like bedrooms and offices as needed. Structurally, it employs a reinforced concrete frame with composite walls of fiber cement boards, providing high overall rigidity and suitability for construction site dormitories, field research stations, and other scenarios demanding high environmental adaptability.
3. Row House Type (Combined Villa): Formed by horizontally or vertically splicing modular units into multi-unit buildings, it uses shared load-bearing walls to reduce material waste. For example, semi-detached villas can share water and electricity through central connection modules, while triple villas can be equipped with communal courtyards. Its core advantage lies in high land utilization (saving 30%-50% of land compared to traditional villas) and adaptability to different family sizes by adjusting module quantities, commonly used in resort areas and retirement communities.

II. Structural Design and Material Characteristics

1. Integrated Design: Utilizing a reinforced concrete integrated pouring process, beams, columns, and floor slabs form a continuous load-bearing system, achieving an earthquake resistance of over 8 degrees (compliant with GB 50011-2010 standard) and a fire rating of Class A (fire endurance ≥ 2 hours).
2. Modular Concept: The house is divided into standard 2m×6m modules, each containing complete water and electricity pipelines, door and window systems, and interior wall finishes. With a factory prefabrication rate of over 90%, only module对接 (connection) and minor decoration work are required on-site, shortening the construction period by 50%-70% compared to traditional buildings.
3. Composite Wall Structure: The outer layer uses 150mm thick reinforced concrete panels for structural strength, the middle layer is filled with 50mm thick rock wool panels (thermal conductivity ≤ 0.04W/(m·K)) for efficient thermal insulation, and the inner layer is covered with 12mm thick fiber cement boards as decorative substrates, forming a "load-bearing-thermal insulation-decoration" three-in-one system.
