In recent years, the problem of color steel tile houses in China has attracted more and more attention, and some places have even directly announced the decision to "demolish" color steel tile houses. In fact, there are many safety hazards in this kind of house, so it is necessary to order the demolition of the color steel tile house. The following will be from three aspects of the hazards of color steel tile houses, and why "must be demolished".
Structural problems of color steel tile houses. The structural design of the color steel tile house is generally composed of steel and other lightweight materials, which has certain advantages such as lightweight, high strength and corrosion resistance, but the seismic performance of this kind of house is relatively weak, and it is easy to be affected by the first grade, which poses a potential threat to personal safety. In addition, there are material problems in color steel tile houses, and these steel and other lightweight materials may contain harmful substances such as PTFE, which are flammable and release harmful substances, and in the event of a fire, it is easy to cause serious personnel and property losses.
The fire performance of the color steel tile house is poor. The metal sandwich panels used in the color steel tile house are usually non-combustible materials, but if the fire prevention measures are not in place, it is prone to fire. According to the national "Code for Fire Protection Design of Buildings", the metal sandwich panels used in the building should be non-combustible materials, and fire prevention measures should be taken, such as the use of rock wool boards and fireproof cotton as fillers, equipped with simple fire extinguishing equipment, fire alarms should be installed if possible, and a safety distance of 6 meters should be maintained from the surrounding color steel plate houses. Therefore, in the event of a fire, the escape passage and fire extinguishing and rescue conditions of the color steel tile house are very unfavorable, and there are great potential safety hazards.
The environmental protection problem of color steel tile houses is also quite serious. During the manufacturing and use of steel and other lightweight materials used in the color steel tile house, a large number of harmful substances and pollutants, such as carbon dioxide, hydrocarbons, dust, etc., will be produced, causing serious pollution and damage to the environment. The raw materials for the production of color steel tiles are steel and other lightweight materials, which contain harmful substances such as PTFE, and the long-term accumulation and emission of these harmful substances will not only damage people's health, but also lead to problems such as global warming.
To sum up, there are many hazards in the structure, fire prevention, environmental protection and other aspects of the color steel tile house. In order to ensure the safety of people's lives and property and improve the quality of construction, it is necessary to order the demolition of color steel tile houses. In addition, the state has also carried out a comprehensive inventory and rectification of the problem of rural color steel tile houses, and some areas have issued notices requiring the demolition of the prohibition of occupying cultivated land to build houses and burning straw in rural areas since March, and the rectification of the problem of multiple houses in one household is also being promoted, hoping that farmers and brothers will pay attention to policy requirements and avoid stepping on the red line. In the future development of buildings, we should explore new and environmentally friendly building materials and technologies to reduce the damage to the environment and the waste of resources.
Can the color steel tile house be renovated to make it more safe and reliable? Are there more environmentally friendly color steel tile house manufacturing technologies and materials? What will be the future development of color steel tile houses? These questions deserve further study and study.
