Yunnan Lijiang Cement Prefabricated Houses

Yunnan Lijiang cement prefabricated houses offer advantages such as strong earthquake resistance, low cost, and short construction periods, with government subsidies available in some regions.

1. Outstanding Earthquake Resistance
Cement prefabricated houses perform exceptionally well in earthquake-prone areas. Taking the prefabricated cement houses near the Ludian earthquake site in Yunnan as an example, their earthquake resistance is eight times that of traditional brick-and-mortar structures. The structure is poured with C35 concrete, with built-in φ12-18 threaded steel bars, and each column is reinforced with up to eight bars, forming a high-strength load-bearing system. Modules are welded together using E55 welding rods, with each joint capable of withstanding 20 tons of tensile force. The steel bar mesh acts like a 'building spring,' absorbing energy through elastic deformation during earthquakes, effectively reducing structural damage. The Ludian case shows that such houses remain stable after multiple aftershocks, with post-disaster repair costs of only 300 yuan/㎡, 62.5% lower than those of brick-and-mortar houses (800 yuan/㎡).

2. Significant Cost and Construction Period Advantages
The main construction cost of cement prefabricated houses is 880 yuan/㎡, 10% lower than that of brick-and-mortar structures (980 yuan/㎡). For a 100㎡ house, this directly saves 10,000 yuan. The construction period is only 15 days, 75% shorter than the 60 days required for brick-and-mortar structures, reducing labor costs from 15,000 yuan to 8,000 yuan. Additionally, earthquake-resistant design reduces post-disaster repair costs, offering better long-term economic efficiency.

3. Policy Support and Industrial Foundation
In high-intensity earthquake zones such as Sichuan, Yunnan, and Gansu, the government provides subsidies of up to 50,000 yuan per household to promote earthquake-resistant housing. Lijiang-based enterprise 'Lijiang Jianping Cement Products Co., Ltd.' has ventured into prefabricated building business, with its 'New Cement Prefabricated Product Production Line Upgrade and Expansion Project' located in the cultural area of Gucheng District, covering an area of 41.07 acres and possessing large-scale production capacity. The company promotes the transformation of house construction towards 'machine production' through the industrialized model of factory-based production of prefabricated components and on-site assembly, aligning with modern architectural development trends.

4. Technical Standards and Material Guarantees
Cement prefabricated houses adopt standardized design, with a concrete strength grade of C35, scientific steel bar configuration, and strict welding processes, ensuring structural safety. Modular production reduces on-site construction errors, offering higher quality controllability than traditional brick-and-mortar structures, making them particularly suitable for areas with complex geological conditions and high earthquake risks.
