With the development of modern construction industry, the term “prefabricated building” is frequently mentioned from top to bottom. Prefabricated building, “building like building blocks”, has become a new trend in the international construction industry. This is not new. It started in Germany in the middle of the 19th century and was invented with the innovation of building materials. As early as the 1950s, during the first five-year plan period, China began the exploration of prefabricated buildings.
With the increase of labor cost, the improvement of environmental protection requirements, and the improvement of occupational health and operating environment of the labor force, it is an inevitable trend for the construction industry to develop toward the direction of building industrialization, and the prefab construction mode is bound to become the mainstream of the development of the construction industry.
The prefab way of production is different from the traditional way of construction, which often gives people the impression that the construction site is noisy, dusty and full of garbage. But compared with traditional buildings, prefabricated buildings behave very differently. “In addition to reducing environmental pollution during construction, it also significantly reduced the amount of dust and construction waste by 70 percent.
Compared with the traditional construction method, it can save water by 25%, reduce the amount of plastering mortar by about 55%, save the template by about 60%, reduce the energy consumption by 20%, greatly reduce the energy consumption in the construction process, improve the project quality and labor production efficiency, and shorten the comprehensive construction period by 25%-30%.
With the gradual improvement of prefabricated building technology research, the rise of labor cost and the increasing voice of green building, China is ushering in a new stage of prefabricated building development.
