Prefabricated Panel Houses in Jiaocheng County
Jiaocheng County has not introduced a specific policy exclusively targeting prefabricated panel houses. Their management primarily relies on the urban and rural housing safety inspection and self-built housing rectification system, with specific measures as follows:
1. Inspection and rectification scope covers prefabricated panel houses According to the 'Urban and Rural Housing Safety Inspection and Rectification Plan' issued by Jiaocheng County in 2020, all urban and rural housing structures in the county are subject to comprehensive inspections, with a focus on six categories, including rural self-built houses used as business premises, crowded venues, and old residential areas. If prefabricated panel houses fall into these categories (such as old residential areas or commercial self-built houses), they must undergo safety hazard inspections, with identified issues addressed immediately. For example, if a prefabricated panel house has issues like wall cracks or loose connection joints, immediate reinforcement measures are required.
2. Self-built housing rectification involves prefabricated structures The 'Jiaocheng County Self-Built Housing Safety Rectification Implementation Plan' implemented in 2022 specifies a '地毯式' (地毯式 means 'comprehensive and thorough') inspection of all urban and rural self-built houses in the county, with a focus on commercial self-built houses. If prefabricated panel houses exist as self-built houses, they must complete safety hazard rectification between June 2022 and May 2024 and be included in the urban and rural self-built housing data management platform. During the rectification process, key parts such as the load-bearing structures and connection joints of prefabricated panel houses must be inspected to ensure compliance with safety standards.
3. Addressing common issues with prefabricated panel houses Prefabricated panel houses generally have issues such as weak earthquake resistance, poor sound and heat insulation, and a lifespan of approximately 30-50 years. During inspections and rectifications in Jiaocheng County, key parts such as the load-bearing structures and connection joints of these houses may be specifically checked based on their structural characteristics. For example, if a prefabricated panel house lacks sufficient earthquake-resistant structural measures, measures such as adding structural columns and ring beams may be taken to enhance earthquake resistance; if connection joints are corroded or loose, anti-corrosion treatment or re-reinforcement may be required.
4. Handling principles under the old housing renovation policy According to the old housing renovation policy implemented since 2022, prefabricated panel houses are primarily repaired and renovated, with only buildings that meet the criteria for dangerous houses being demolished. If there are prefabricated panel houses in Jiaocheng County that require renovation, priority may be given to enhancing safety through reinforcement and facility updates rather than large-scale demolition. For example, measures such as thermal insulation treatment for the exterior walls of prefabricated panel houses, replacement of aging doors and windows, and addition of fire safety facilities may be taken to extend the lifespan of the houses and improve living conditions.
