In recent years, with the rapid development of China’s social and economic construction, the situation of load, three-dimensional, large area, large space modern fire and mine collapse, super typhoon, leakage of dangerous chemicals and other major disasters and accidents is increasingly severe, and the development of China’s fire protection industry has been severely challenged.
       In the process of industrial production, due to improper management, technical defects and other reasons, there are often fire and explosion accidents, resulting in serious property losses or casualties. With the development of modern industry, the production process is more and more complex, and the risk and harmfulness of industrial medium fire and explosion are also increasing. Therefore, the problem of fire and explosion prevention has become a social concern and the top priority in production safety.
        Fire accident is very destructive. Once a fire accident happens, it will cause serious consequences. Therefore, it is of great significance to study the basic knowledge of fire and explosion, master the general rules of such accidents, and take effective fire and explosion prevention measures for the development of national economy. It is hoped that through this course, students can understand the hazards of fire and explosion disasters, be familiar with and master the basic theory and technical methods of preventing and controlling fire and explosion disasters, so as to effectively prevent the occurrence of fire and explosion accidents, ensure the life safety of operators and reduce property losses.
      If there is a fire, it will cause great harm to the building residents. In order to strengthen the residential fire prevention management effect, we need to consider the existing problems in the field of building fire prevention, innovate the management content, do a good job in fire prevention supervision and management, and ensure the property safety and personal safety of the public.

随着社会经济各方面的快速发展，我国的现代建筑技术的发展速度也越来越快，建筑工程也必须走向绿色节能的发展道路以适应现代社会的发展。在全国经济建设的热潮下，早期的建筑行业一直是粗放式的发展模式，污染大、资源消耗多和施工混乱是这一时期的典型特征。装配式建筑是以精细化设计、智能化生产、机械化总装和信息化集成的绿色建筑，可以助推住宅业供给侧改革，以高科技制造业模式引领传统住宅业的转型升级。
       当前，我国住宅产业主要朝着装配式住宅建设技术的方向发展，并且将其和绿色建筑的发展理念相结合，也就是在保证建筑的使用寿命、实用性的基础之上，尽可能地做到节能减排，即节约能源、土地、材料等，尽量减少污染排放，给人们创造安全健康、实用美观的住宅环境。在住宅建设中，特别是在保障性住宅建设中一定要将绿色建筑的原则融，人设计中，努力实现住宅建设的标准化和装配化。

Prefabricated building refers to the construction of prefabricated parts assembled in the construction site, which has six characteristics: standardized design, fine design, factory production, prefabricated construction, integrated decoration and information management. Prefabricated steel structure building originated from Europe and America in the form of prefabricated steel structure residential system. In recent decades, it has formed a set of very mature technology, and has been further researched and developed in Japan, making it an ideal product to improve human living environment in the 21st century.
  Construction industry is one of the pillar industries in China, and it is an important industry serving the national economy and social development. In recent years, with the implementation of the national comprehensive deepening reform and the acceleration of the new urbanization construction process, new requirements for the transformation and development of the construction industry have been put forward. The transformation and upgrading of the construction industry should focus on changing the traditional high consumption production mode, that is, developing the construction industrialization. Steel structure building is a kind of green building. It is easy to realize the standardization of design, factory production of components and fittings, and assembly of on-site construction. It is the most suitable building structure for prefabricated industrial construction. Prefabricated steel structure in the construction and installation process can effectively reduce the manual operation error, reduce the labor intensity, reduce the energy consumption and environmental pollution caused by on-site construction, improve the construction speed and construction quality, and improve the building quality. Its popularization and application can promote the development of the construction industry in the direction of green, energy saving and sustainable, truly realize the fundamental transformation of construction technology, and promote the international development of China’s economy
