Prefabricated Floor Slabs of Houses in Wuyuan County
The following is information about the prefabricated floor slabs of houses in Wuyuan County:
Existing Problems
The existing prefabricated slab houses in Wuyuan County have multiple issues. Weak earthquake resistance is a prominent problem. Due to the structural characteristics of prefabricated slab houses, their overall structural stability is poor when encountering natural disasters such as earthquakes. They are difficult to effectively resist the impact of seismic waves and are prone to damage or even collapse, posing a threat to the lives and property of residents. Poor sound insulation and thermal insulation performance is also a common issue. The splicing gaps between prefabricated slabs and the properties of the materials themselves allow external noise to easily enter the interior, while indoor heat is also easily lost, affecting the living comfort of residents. In addition, limited service life, generally around 30 - 50 years. As time goes by, the structure and performance of the houses will gradually decline, leading to various safety hazards.
Policy Situation
Since 2022, China has implemented the old-community renovation policy, with the main approach for dealing with prefabricated slab houses being repair and renovation. This means that for most prefabricated slab houses that have not yet reached the standard of dangerous buildings, their safety and living quality will be improved through methods such as repair, reinforcement, and renovation, rather than direct demolition and reconstruction. Only when the prefabricated slab houses reach the standard of dangerous buildings, that is, when there are serious safety hazards that may endanger the lives of residents, will they be demolished.
Inspection and Management
The County Housing and Urban-Rural Development Bureau has carried out quarterly inspections of prefabricated slab houses. The inspections follow the principle of "precise investigation, scientific assessment, and closed-loop handling". Experts and key personnel cover towns and townships in sections to conduct comprehensive and detailed inspections of prefabricated slab houses. They focus on checking the connection of prefabricated slabs, the condition of floor slabs and walls, and the foundation to ensure the structural safety of the houses. For key houses, they will also conduct "follow-up inspections" and establish electronic files of "one file per house" through instrument detection and other methods to record the safety status and inspection details of the houses in detail. At the same time, they popularize housing safety knowledge among residents to improve their safety awareness and self-protection ability. In the future, they will also solidify the inspection model, strengthen joint action and grid management, accelerate the elimination of hidden dangers, and improve emergency plans to ensure the living safety of residents in prefabricated slab houses.
