Introduction to the characteristics of prefabricated buildings

Release time:


In the past few decades, China's construction industry has developed vigorously, which has promoted the growth of the national economy. With the increasing cost of land transfer, the rising cost of labor and the gradual improvement of the consciousness of energy conservation and environmental protection requirements, the construction industry is facing more and more international competition pressure. In order to improve the core competitiveness, a new industrial model has emerged--prefabricated building.


  prefabricated buildingThe basic concept is to use prefabricated components to assemble the building on the site. As early as the beginning of the 20th century, assembled architecture attracted widespread attention, and early embryonic forms have been seen in attempts in countries such as Britain and France. The construction speed of prefabricated buildings is fast and the production cost is low, so it is rapidly popularized in the world. At present, with the development of science and technology in China and people gradually improve the awareness of energy conservation and environmental protection, prefabricated buildings have been paid attention to, by the influence of prefabricated buildings in developed countries, and gradually developed for China's construction technology, have good results.

  prefabricated buildingThe characteristics

(1) Multiple roles

A lot of assembly work was done on site, and the original field work was greatly reduced. The production efficiency is improved and the cost is saved. The main advantage of prefabricated buildings is energy saving. The exterior wall design has a thermal insulation effect, which can make the landlord feel warm in winter and cool in summer, save the number of air conditioners and reduce air pollution. The sound insulation is good, and the sealing effect of the walls and windows is strong enough to shield a lot of outside noise. Fire-proof, anti-seismic, anti-seismic, special materials for prefabricated buildings can provide a living environment and are not easy to ignite spontaneously in dry weather. The appearance is not particularly luxurious, but long-term use will not appear cracks and yellowing and other problems. When an earthquake occurs, the solidity of the building is not easy to make the house collapse.

2. Construction assembly

A large number of architectural works are completed by the factory production and processing. The main types of components are exterior wall panels, interior wall panels, laminated panels, balconies, air conditioners, stairs, prefabricated beams, prefabricated columns, etc. Its precision conforms to the national quality inspection standards. Prefabricated buildings adopt the integrated design and construction procedures of building and decoration, and the ideal state is that the decoration can be carried out at the same time as the main construction. In addition, because the weight of prefabricated buildings is lighter than ordinary buildings, drawing basic structural drawings can be directly constructed on the construction site. The construction speed of prefabricated buildings is very fast, it can be lived in a short time, the number of workers on the construction site is reduced, and the work efficiency is greatly improved. When carrying out various engineering processes, the prefabricated building should ensure the quality and operate in accordance with strict regulations. The on-site construction sound is small and does not affect the rest time of the surrounding residents.
