Prefabricated Houses in Baise, Guangxi
In the Baise region of Guangxi, the architectural forms related to prefabricated houses mainly include steel-structure residential buildings and steel-structure panel houses. Details are as follows:
Steel-Structure Residential Buildings
Their load-bearing skeletons are connected by hot-rolled or welded steel structural members. The tensile and compressive strength of steel is significantly higher than that of concrete, and the cross-sections of the members are smaller, allowing for greater usable space. Steel has good ductility and can resist dynamic loads (such as earthquake forces), making it suitable for mountainous areas with complex geological conditions. The main structure is prefabricated in the factory and quickly installed on-site, reducing the time for open-air wet operations and minimizing the impact of rainy-season construction on the schedule and quality. The precise prefabrication characteristics enable it to better adapt to uneven terrain in mountainous areas and reduce extensive excavation of the original terrain. The system consists of the main structural system (steel columns, steel beams, supports, etc.), the floor system (composite floor slabs made of profiled steel sheets and concrete), the enclosure system (lightweight wall materials, such as autoclaved aerated concrete panels, etc.), and the equipment and pipeline system (pipelines separated from the structure for easy maintenance and replacement).
Steel-Structure Panel Houses
These use steel as the main load-bearing skeleton, combined with a panel enclosure structure. Steel has high strength and can withstand large loads, with good plasticity and toughness. The panels usually refer to colored galvanized steel sheets, sandwich panels, etc., with surface coatings providing corrosion resistance and some thermal insulation. The construction process includes foundation treatment, steel structure installation (precise connection of primary and secondary members such as columns, beams, and purlins, mostly using bolts or welding), and panel installation (connected to the steel structure with self-tapping screws and other fasteners, with proper sealing of the joints). Their performance characteristics include fast construction speed, as most components can be prefabricated in the factory, reducing on-site work and shortening the overall project duration. The main structure and enclosure panels can be separated, providing technical feasibility for future possible relocation or renovation. Regular anti-rust maintenance of the steel structure and inspection of the firmness of connection nodes are required to extend the service life. They are commonly used in temporary or semi-professional settings where the construction period is a concern, and the interior space can be flexibly divided with non-load-bearing partitions.
In addition, Baise City has integrated the concept of sponge city construction into the renovation of dilapidated houses (shantytowns), adhering to the synchronous planning, construction, and delivery of supporting facilities, thereby improving the quality of urban living.
