History of Steel-Concrete Prefabricated Houses

The history of steel-concrete prefabricated houses (prefabricated concrete houses) can be traced back to the 1950s, with its development integrating international experience and local practices, serving as a microcosm of the evolution of industrialized construction technology.

Origin and Early Applications: Technology Introduction Influenced by the Soviet Model

In the 1950s, China began to introduce prefabricated concrete technology. Influenced by the Soviet architectural model, prefabricated components were gradually applied in industrial plants, residential buildings, and office buildings. During this period, prefabricated houses mainly consisted of simple components such as prefabricated floor slabs and wall panels, primarily addressing the need for rapid construction. The technological characteristics included low standardization and a single type of component, but they laid the foundation for subsequent development.

Industrialization-Driven Technological Deepening: Structural Support from International Experience

The technological foundation of prefabricated construction can be traced back to earlier international practices. In the 1890s, German builder F. Hennebigue constructed a complete house using reinforced concrete for the first time. The Saut-Jean de Montmartre Church, built in France in 1894, demonstrated the artistic potential of reinforced concrete structures. These practices provided structural theoretical support for prefabricated concrete technology. The Crystal Palace in London, built in 1851 through factory-prefabricated components and on-site assembly, pioneered the prefabricated construction technology model. In 1921, French architectural master Le Corbusier proposed the concept of "building houses like making cars," driving the construction industry towards standardization and industrialization, and further clarifying the development direction of prefabricated construction.

Large-Scale Application Phase: Breakthrough from Components to Overall Assembly

From the late 1970s to the mid-1980s, prefabricated concrete construction was widely adopted for single-story industrial plants in China, with the main structural form being assembled large-panel structures. During this period, prefabrication technology evolved from simple components to overall assembly, significantly improving construction efficiency. For example, through on-site assembly of prefabricated wall panels, floor slabs, and roof trusses, the construction period was greatly shortened. Meanwhile, the accuracy and quality control systems for prefabricated components were gradually improved, promoting the process of building industrialization.

Evolution of Materials and Structures: Competition and Coexistence of Steel and Concrete

After the 1960s, steel-structured buildings gradually dominated due to their advantages in seismic performance and short construction periods. However, prefabricated concrete continued to be applied in residential and industrial plants due to its low cost and good durability. For example, in earthquake-prone areas, steel structures became the preferred choice, while in cost-sensitive residential projects, prefabricated concrete remained competitive. This competition drove continuous innovation in prefabrication technology, such as the emergence of composite structural systems that combined the advantages of steel and concrete.
