What are the advantages and disadvantages of prefabricated buildings?

Traditional architecture, also known as cast-in-place integral structure, refers to pouring construction directly on the construction site. Prefabricated building refers to prefabricated components produced by the factory and then transported to the construction site for direct use, similar to building blocks. So, what are the advantages and disadvantages of prefabricated buildings? What are the problems in the construction of prefabricated buildings? Let's take a look with Bian Xiao. I hope it helps you!

First, the advantages and disadvantages of prefabricated buildings

1, advantages of prefabricated buildings

① Good quality: spare parts are not affected by weather changes, and can be standardized and mass-produced, with more reliable quality;

② Energy-saving and environmental protection: Assembled 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) saving manpower: the construction is directly produced by the factory, which reduces the manpower demand and reduces the labor intensity of the construction workers;

2. The disadvantages of prefabricated buildings

① Cost increase: the cost of traditional construction projects is much cheaper than that of assembled construction projects;

(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: It is easy to limit the production equipment due to inconsistent parts sizes, so it will be difficult to produce larger parts;

(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.

Second, what are the problems in the construction of prefabricated buildings?

1. Parts supply problems mainly include nonstandard methods in production, transportation, inspection, accumulation and maintenance. These problems have damaged components to some extent, affected the quality and quantity of components, and directly or indirectly affected the quality of prefabricated buildings.

2. The lack of foresight in prefabrication construction preparation, scientific quality plan and construction scheme, and inadequate preparation of personnel, materials and mechanical equipment during construction will all affect the overall quality control requirements in comprehensive construction.

3. The unqualified use of construction personnel and machinery, insufficient attention to the important parts of prefabricated buildings, easy to cause weak lap joint of components, weak concrete pouring strength, substandard lap joint of steel bars, and weak integrity of building structure, which has a negative impact on construction quality.

4. Imperfect acceptance standard of construction also leads to the loss of strict constraints on construction quality, which will affect the development of prefabricated buildings.

Editor's summary: I believe everyone will understand the advantages and disadvantages of prefabricated buildings and related problems in the construction of prefabricated buildings after reading the article. In a word, both traditional buildings and prefabricated buildings have their own advantages and disadvantages and problems in construction.
