Prefabricated Baoshan Housing

Some houses in Baoshan are indeed built using prefabricated panels. Here is a detailed introduction to the use of prefabricated panels in Baoshan housing construction:

I. Old residential areas built with prefabricated panels There are some old residential areas in the Baoshan area that were built using prefabricated panels, with typical examples being Baoshan Village 1 and Baoshan Village 2. These areas were constructed relatively early. At that time, the technology of building with prefabricated panels was widely applied. Prefabricated panels had advantages such as fast construction speed and relatively low cost, which could meet the demand for large-scale housing construction. Therefore, they became the choice for building these residential areas.

II. The relationship between 'small-beam and thin-panel' buildings and prefabricated panels Residential areas such as those at 571, 581, 591, 601, and 611 Baoshan Road, and 490 Dongbaoxing Road belong to 'small-beam and thin-panel' buildings. These types of buildings emerged in large numbers in the 1950s. Their construction method involved using precast concrete thin panels and small-beam structures. Essentially, 'small-beam and thin-panel' buildings are a specific form of construction using prefabricated panels. They are formed by assembling pre-made thin panels and small beams to create the basic structure of the house. This form of construction played an important role in addressing the housing shortage under the specific historical conditions of that time.

III. Characteristics of houses built with prefabricated panels Houses built with prefabricated panels may have certain deficiencies in terms of sound insulation and heat insulation. Due to the presence of joints between the prefabricated panels, sound and heat can easily spread through these gaps, resulting in relatively poor indoor sound insulation and heat insulation effects. Moreover, as time goes by, the prefabricated panels may experience aging and cracking, which can affect the structural safety and service life of the house. However, for some old prefabricated panel houses that have been renovated and reinforced, their performance can be improved to a certain extent.
