What are the disadvantages of prefabricated buildings?
2. Increased freight: As the components are directly transported from the factory to the construction site, if the distance between the factory and the construction site is too far, the transportation cost of transporting components will increase;
3. Size limitation: As the sizes of components are inconsistent, it is easy to limit the production equipment, so it will be difficult to reproduce larger components;
4. Small application field: Although the country vigorously promotes prefabricated buildings, the total height and story height of prefabricated buildings are greatly limited at present;
5. Poor seismic capacity: Due to the weak integrity and rigidity of prefabricated buildings, the seismic capacity of prefabricated buildings is poor.
Extended data:
Advantages of prefabricated buildings:
1, good quality: components are not affected by weather changes, can be standardized and mass produced, and the quality is more reliable;
2. Energy conservation and environmental protection: prefabricated buildings can reduce the harmless loss of materials in the construction process and reduce the construction waste at the construction site;
3. Shorten the construction period: due to the reduction of some working procedures, the components are directly transported to the site for assembly after being completed by the production workshop, which also speeds up the construction progress;
4. Save manpower: the construction is directly produced by the factory, which reduces the manpower demand and reduces the labor intensity of the construction personnel.
