Are There Prefabricated Houses in Pengshan?

There are prefabricated houses in Pengshan, mainly old-style prefabricated panel buildings. Here is a detailed introduction:

Existence

A large number of old-style prefabricated panel buildings remain in the core urban area of Pengshan District. Prefabricated panel buildings are a common type of early architecture, using prefabricated panels as the main components of the floor. These prefabricated panels are usually pre-made in factories and then transported to the construction site for installation and assembly, enabling the rapid construction of the building's floor structure. These old-style prefabricated panel buildings in the core urban area of Pengshan have witnessed the local urban development process and are a manifestation of architectural styles from a specific historical period.

Structural Characteristics

Old-style prefabricated panel buildings have many roof assembly seams. Since the prefabricated panels are assembled piece by piece, seams are inevitable at the assembly points. Over long-term use, these seams may be affected by factors such as wind and rain erosion and temperature changes, gradually showing signs of aging and cracking. At the same time, their gutter drainage systems are relatively old. Gutters are an important part of a building's roof drainage. Old gutter drainage systems may have issues such as poor drainage and blockages. In the event of heavy rain, they cannot effectively and promptly drain roof rainwater, easily leading to water accumulation on the roof.

Performance Issues

These old-style prefabricated panel buildings have weak resistance to temperature differences and heavy rain. In the case of large temperature differences, the prefabricated panels will generate stress due to thermal expansion and contraction, and the presence of assembly seams affects the release of this stress, easily leading to cracks and deformation in the prefabricated panels, affecting the structural safety and service life of the building. During heavy rain, the old drainage system cannot drain water in a timely manner, and a large amount of water accumulation on the roof will increase the load on the building. At the same time, rainwater may seep into the interior through the assembly seams, causing damage to the building's decoration and internal facilities.
