Heilongjiang Prefabricated Panel Houses

Here is information about prefabricated panel houses in Heilongjiang:

Policy Regulations: Heilongjiang's policies for prefabricated panel buildings over 30 years old follow national guidelines, involving expropriation, compensation, old-building renovation, and dangerous building reconstruction. If a building's area is designated by the government for expropriation, such as for affordable housing construction or old urban area renovation, the government will make an expropriation decision in accordance with the law, and the expropriated will receive reasonable compensation, including the value of the house, relocation, and temporary accommodation expenses. For prefabricated panel buildings over 30 years old that still meet living conditions, Heilongjiang tends to carry out old-building renovations, such as painting exterior walls, repairing water and electricity circuits, and installing elevators. If a building is identified as a dangerous building with serious safety hazards, the government will require renovation or reconstruction, which may involve government subsidies, residents raising funds themselves, or cooperation between the government and enterprises.

Distribution: The proportion of prefabricated panel residential buildings in Harbin City is as high as 22.3%, ranking first in the country, and they are mostly found in old residential areas or residential areas built during specific periods.

Structural Characteristics: Prefabricated panel houses are built using prefabricated components, including prefabricated floor slabs, wall panels, and balcony panels, which are prefabricated in factories and then transported to the construction site for assembly. They have the advantages of high efficiency, speed, and relatively low cost.

Existing Problems:

• Poor Thermal Insulation: When built, thermal insulation design was not considered. The thickness of the wall panels is far below modern standards, with a high heat transfer coefficient, resulting in severe heat loss during winter heating.
• Poor Waterproofing: The sealant in the gaps between prefabricated panels has aged and failed, with about 83.6% of residential buildings experiencing water leakage problems, affecting living comfort and accelerating structural aging.
• Poor Sound Insulation: The joints and hollow parts of prefabricated panels reduce sound insulation performance.
• Safety Hazards: The long age of the buildings leads to material aging, and actions such as unauthorized wall removal during renovations can damage the structure, easily triggering collapse accidents.

Inquiry Methods: You can determine whether a house is a prefabricated panel structure by checking local building archives, conducting on-site inspections of the house's structural characteristics, or consulting real estate professionals or architects.
