Qujing Prefabricated Assembly Houses
Prefabricated assembly houses in Qujing mainly include types such as light steel villas, movable plank houses, and prefabricated steel structure near-zero energy consumption demonstration buildings.
Light steel villas are a relatively common type of prefabricated assembly house in Qujing. They use high-strength galvanized and aluminum-zinc coated steel materials like S550Az150, which endow light steel villas with many excellent characteristics. They have sound insulation and warmth retention, fire and moisture resistance, earthquake and wind resistance, effectively withstanding the impact of external environmental changes on the house. At the same time, light steel villas do not crack or hollow out, are easy to construct, have an aesthetically pleasing appearance, offer a large usable floor area, can support heavy hanging objects, and have a long service life. In terms of applications, they are mainly used in scenarios such as rural self-built houses, rural villas, and tourist homestays. Prices vary depending on material selection and area, with quotes ranging from 450 yuan to 1460 yuan per square meter.
Movable plank houses adopt standardized and modular designs, using lightweight steel as the framework and composite sandwich panels and other materials for walls and roofs. After prefabrication in the factory, they can be quickly assembled on-site. Their construction speed is extremely fast, meeting usage needs in a short time; they are highly economical with relatively low costs; they offer high flexibility, allowing layout adjustments according to different needs; their quality is relatively stable, and they have a small environmental impact. Movable plank houses are suitable for short-term projects, temporary events, emergency shelter, and other scenarios. For example, on some construction sites, movable plank houses can serve as temporary dormitories and office spaces for workers.
The 200-square-meter prefabricated steel structure near-zero energy consumption demonstration building constructed by Qujing Langying Metal Components Co., Ltd. is an innovative practice in the field of energy conservation for prefabricated assembly houses in Qujing. This demonstration building adopts active energy-saving technologies such as high-performance doors and windows and wall panels, efficient heat recovery fresh air systems, and building-integrated photovoltaics, achieving the goal of energy-saving and low-carbon green buildings. During the construction process, key technical aspects such as thermal bridge-free, highly airtight thermal insulation systems and prefabricated construction were studied, providing valuable exploration and reference for the future development of green buildings.
