Prefabricated Houses in Baise, Guangxi
The practice of prefabricated houses in Baise, Guangxi, primarily takes the forms of steel-structure residences and box-type houses, each with distinct characteristics in construction methods, application scenarios, and policy support.
Steel-Structure Residences: Combining Industrial Construction with Terrain Adaptability
The load-bearing framework of steel-structure residences is formed by connecting hot-rolled or welded steel members. Their core advantage lies in the separation of the main structure from the enclosure system. After the main structure is prefabricated in the factory, it is quickly installed on-site using bolts or welding, significantly reducing the time spent on outdoor wet operations. This is particularly suitable for Baise's long rainy season, as it minimizes the impact of rain on construction schedules and quality. Additionally, steel-structure residences are highly adaptable to terrain, eliminating the need for extensive excavation of uneven mountainous sites. Stable construction can be achieved by adjusting the foundation type, reducing damage to the ecological environment.
At the policy level, a notice issued by nine departments, including the Housing and Urban-Rural Development Department of the autonomous region, explicitly requires the promotion of prefabricated components such as stair treads, floor slabs, and interior and exterior wall panels, providing technical specification support for the prefabricated development of steel-structure residences. For example, prefabricated stair treads and floor slabs can be produced in the factory in advance and directly installed on-site, shortening the construction period. Prefabricated interior and exterior wall panels enhance the overall performance of the building through standardized design, driving the upgrading of steel-structure residences towards industrialization and modularization.
Box-Type Houses: A Model of Modular Design and Efficient Construction
Box-type houses are centered around high modularity and prefabrication. Each room unit completes most of the processes for the main structure, insulation layer, water and electricity pipelines, and interior decoration in the factory, forming an independent 'box' before being transported to the site for assembly. Their standardized production model ensures controllable component quality, with on-site construction involving only foundation treatment, module lifting, and connection debugging, reducing the construction period to less than one-third of that of traditional buildings.
Box-type houses are particularly suitable for temporary and periodically migratory scenarios, such as post-disaster reconstruction and temporary construction site housing. Through anti-corrosion and fire-resistant treatments and the use of high-quality insulation materials, their service life far exceeds that of traditional temporary buildings, reaching 10-15 years. Furthermore, the modular design concept of box-type houses synergizes with the joint acceptance policy of 'efficiently accomplishing tasks' in urban renewal, optimizing the approval process and further shortening project implementation time.
Policy Synergy: Driving the Implementation of Prefabricated House Technology
The development of prefabricated houses in Baise, Guangxi, is inseparable from policy guidance. The autonomous region promotes the use of prefabricated components, providing technical specifications for steel-structure residences. Meanwhile, the modular design of box-type houses combines with joint acceptance policies to streamline approval processes. Together, they form a comprehensive support system from production to implementation, laying the foundation for the popularization of prefabricated houses in Baise.
