Luliang Concrete Prefabricated Houses
Luliang has achieved relatively comprehensive development in concrete prefabricated houses, covering multiple aspects such as materials, processes, and policy promotion, and possesses distinctive lightweight aggregate concrete materials.
At the material level, concrete prefabricated houses in Luliang have realized the transformation of building materials from on-site processed products to industrialized products. Basic materials such as concrete are pre-processed and compounded in factories according to precise drawings and proportions, ensuring that the dimensional errors of each manufactured component are controlled at the millimeter level. Their homogeneity and reliability far surpass the results of on-site manual operations, providing a solid guarantee for the quality of the houses.
In terms of processes, prefabrication processes demonstrate significant advantages. During the manufacturing stage of wall components, insulation layers, window embedded parts, pipeline channels, and even decorative surface layers can be compounded in one go, forming "sandwich insulation wall panels" or "decorative insulation integrated panels." This integrated process reduces the complexity and conflicts of cross-operations among multiple on-site work types, improves construction efficiency, lowers construction costs, and ensures the integrity and coordination of building functions.
In terms of policy promotion, the Luliang Housing and Urban-Rural Development Bureau has taken proactive actions. It requires that projects invested in by the government and state-owned enterprises, such as affordable housing and talent apartments, adopt prefabricated building technology for construction. For commercial housing development projects that acquire state-owned land use rights through bidding, auction, or listing, those with a floor area of 100,000 square meters (inclusive) or more on the ground should also adopt this technology. For concrete structure projects, components such as composite floor slabs and prefabricated stairs should be fully adopted, and the use of insulation, heat insulation, and decorative integrated panels should be promoted. The separation of pipelines and dry construction methods should be accelerated, and the full decoration of prefabricated buildings should be implemented, effectively promoting the popularization and development of concrete prefabricated houses.
In addition, Luliang lightweight aggregate concrete has unique advantages. It is made from lightweight aggregates and other materials, featuring characteristics such as light weight, thermal insulation, and sound insulation. It can reduce the self-weight of buildings, lower energy consumption, and is widely used in non-load-bearing structural parts of buildings, such as walls and roof slopes, providing high-quality material options for building energy efficiency and further promoting the development of Luliang concrete prefabricated houses towards green and energy-saving directions.
