Assembly of Prefabricated Houses in Rural Qianxian

Currently, there are no publicly available specific processes or cases for the assembly of prefabricated houses in rural Qianxian, but it can be systematically implemented by combining supplier service models, technical specifications, and seismic technologies.

1. Supplier Selection and Full-Process Service Reference

Xi'an Hualong Housing Construction Co., Ltd., as a representative enterprise in the field of prefabricated assembled buildings, can provide a reference for projects in Qianxian with its service model. The company holds qualifications for general contracting of housing construction projects and specialized contracting of steel structure projects, covering the entire process from design, production, to construction. Its products have passed wind and seismic resistance tests. The construction process supports remote video monitoring, and the quotation is transparent with no additional charges, reducing project risks. If the project in Qianxian needs to be implemented quickly, it is recommended to prioritize selecting suppliers with complete qualifications and mature technologies and request them to provide customized design plans for rural scenarios.

2. Technical Specifications and Construction Precision Control

When traditional rural villas in Qianxian adopt brick-concrete structures, there are clear technical requirements for foundation construction, steel bar binding, and other aspects, such as:

• Foundation Construction: A strip foundation should be used to ensure uniform bearing capacity of the foundation;
• Material Standards: The yield strength of steel bars should be ≥400MPa, and the concrete strength grade should meet the design requirements;
• Construction Precision: The axis deviation should be ≤5mm, and the verticality deviation of the wall should be ≤0.3%.
  When assembling prefabricated houses, these specifications should be extended to the component connection环节. For example, high-precision molds should be used to ensure the consistency of component dimensions, bolts or welding processes should be adopted to ensure the strength of connection nodes, and temporary support systems should be set up to prevent deformation during the assembly process.

3. Integration and Application of Seismic Technologies

The seismic reinforcement projects for rural houses in Zhugan Town and Liangshan Town in Qianxian adopt high-ductility concrete reinforcement technology, significantly improving the structural seismic performance by setting vertical and horizontal concrete strips on the walls. **The assembly of prefabricated houses can draw on this technology by adding seismic structural measures at component connections, such as:

• Setting steel bar anchorage nodes at the connections between prefabricated wall panels and foundations and floor slabs;
• Using flexible connectors to absorb seismic energy;
• Wrapping and reinforcing key nodes with high-ductility concrete.**

4. Policy and Information Acquisition Channels

To further understand the special policies or implementation cases for the assembly of prefabricated houses in rural Qianxian, it is recommended to obtain authoritative information through the following channels:

• Contact the Qianxian Housing and Urban-Rural Development Bureau (Phone: 18089186234) to inquire about local subsidy policies, approval processes, and technical standards for assembled buildings;
• Search the Qianxian People's Government Website to keep an eye on the latest bidding announcements and demonstration project updates for practical case references.
