Beijing Rural Prefabricated House Assembly

The assembly of prefabricated houses in rural Beijing adopts prefabricated integrated housing construction technology, belonging to the prefabricated building industry. Components are standardizedly produced in factories and then assembled on-site, offering advantages such as efficiency, environmental protection, and earthquake resistance, and receiving policy support.

Construction Method and Efficiency

The walls, floor slabs, stairs, and other components of prefabricated houses are prefabricated in factories and assembled on-site through bolting or welding, with construction errors controlled within 2 millimeters. Compared to traditional methods, the construction speed of assembled houses is significantly improved: Traditional methods take 7-10 days to build one floor, while assembled houses take only 3-5 days, halving the overall construction period. For example, a farmer in Hebei once completed the construction of a three-story building with an assembled house in two days, and no cracks have appeared in three years.

Core Advantages

1. Reliable Quality:
   Sleeve grouting technology is used to treat joints, achieving an earthquake resistance of over 7 degrees and better crack prevention than traditional cement pouring. Integrated design enables the synchronous embedding of water and electricity pipelines with the structural body, improving installation accuracy and simplifying later maintenance.

2. Environmental Protection and Energy Efficiency:
   Construction waste is reduced by over 60%, with some projects achieving a 30% reduction. The houses come with built-in insulation layers, reducing air conditioning energy consumption and meeting Beijing's requirements for green construction and sustainable development. For example, a pilot project in Fangshan District used environmentally friendly building materials processed from waste plastics, wood chips, and straw, achieving zero formaldehyde, moisture resistance, and heat insulation, with a service life superior to that of ordinary color steel plate houses.

3. Environmental Adaptability:
   Effectively addressing traditional construction challenges such as low temperatures in winter and smog-related work restrictions in Beijing, extending the annual construction period and reducing the impact of weather on project progress.

Policy and Economic Support

Beijing provides a financial reward of 20,000 yuan per household to farmers who adopt assembled houses that meet earthquake resistance and energy efficiency standards, along with a subsidy of 400 yuan per square meter. Market prices vary by brand and specification, such as the custom price of 300 yuan per square meter for cement mobile houses from the Xinwei Hongtu brand, with overall costs lower than those of traditional self-built houses. The construction cost per square meter in the Fangshan District pilot project is approximately 1,800 yuan, further verifying its economic efficiency.

Market and Brands

The Beijing prefabricated panel house market features a variety of brands, including Xinwei Hongtu, Jingweida, and Xinxiang, with assembly methods covering hoisting and assembling types. Brand competition drives technological optimization and cost control, offering farmers diverse choices.
