They are mainly based on factory-produced reinforced concrete prefabricated components, and are designed and constructed through on-site assembly. They are generally divided into two categories: fully assembled buildings and partially assembled buildings. Fully assembled buildings are generally low-rise or multi-story buildings with low seismic fortification requirements; the main components of partially assembled buildings are generally prefabricated components, which are connected on-site through cast-in-place concrete to form assembled integral structures. The characteristics of this building are fast construction speed, which is conducive to winter construction, high production efficiency, good product quality, and reduced material loss.
