Dongying Cement Prefabricated House

The Dongying cement prefabricated house is a building model centered around the production of prefabricated components in factories and on-site assembly. It features high efficiency, environmental protection, and controllable quality, and is widely used in residential, commercial, and public facility construction.

Basic Structure and Principle

The Dongying cement prefabricated house mainly consists of three parts: prefabricated components, foundations, and connectors. Prefabricated components (such as walls, roofs, and floors) are produced in factories using standardized molds to ensure dimensional accuracy and quality stability. The foundation needs to be designed according to geological conditions to bear the load of the house. Connectors (such as bolts and welded parts) fix the components into an integral structure. This model of "factory production + on-site assembly" reduces the wet operation links in traditional cast-in-place operations and significantly improves construction efficiency.

Core Advantages

1. High Construction Efficiency: Factory-prefabricated components can be produced in parallel, and on-site assembly only takes a few days to a few weeks, shortening the construction period by more than 50% compared to traditional buildings.
2. Energy Saving and Environmental Protection: Construction waste is reduced by about 60%, material utilization is increased by 30%, and energy-saving processes are adopted in factory production to reduce energy consumption.
3. Controllable Quality: Components undergo strict testing (such as compressive strength tests), and mechanized production reduces human errors, resulting in higher overall structural safety.
4. Flexible Design: Supports modular combination and can be customized in terms of floor height, house type, and appearance style to meet personalized needs.

Application Areas and Brand Selection

• Residential Buildings: Suitable for rapidly constructed affordable housing and temporary resettlement housing.
• Commercial Buildings: Projects such as shopping malls and office buildings that require shortened construction periods.
• Public Facilities: Places like schools and hospitals that have high requirements for construction speed.

Brand References:

• Yingchuang: Offers various specifications at 350 yuan per unit (such as a 3.75*7.5 double-story house), with a 50-year warranty and support for new Chinese-style structural design.
• Zhuoli Construction: A 3.573 cement house at 360 yuan per unit, using national standard threaded steel, with a self-weight of 25 tons and concrete integral casting.
• Wangjin Group: Reinforced concrete panel houses at 270 yuan per square meter, supporting rectangular customization and suitable for large-scale projects.

Construction and Maintenance Points

• Site Selection: Avoid areas prone to geological disasters (such as earthquake zones and landslide areas) to ensure foundation bearing capacity.
• Design: Structural calculations are required to verify safety, taking into account both functionality and aesthetics.
• Construction: Assemble strictly according to the drawings, ensure that the tightening torque of connectors meets the standards, and avoid misalignment of components.
• Maintenance: Regularly inspect for cracks and water leakage, conduct structural safety assessments every 5 years; keep the interior dry to prevent steel bar corrosion.

Cement Material Selection

Preferably use low-alkali, high-early-strength cement (such as P.O 42.5 ordinary Portland cement), with a mix ratio that meets the designed strength grade (such as C30 concrete). Strictly control the water-cement ratio (≤0.5) during construction to avoid defects such as honeycombing and ensure durability.
