What are the construction characteristics of prefabricated buildings?

The characteristics of prefabricated buildings are: 1. Diversified design. Prefabricated buildings have diversified designs and realize digital management, which will be more cost-effective.

2. Diversified functions. First of all, its exterior walls are designed with the function of thermal insulation; Secondly, the sealing function of the wall, doors and windows is better, and the sound insulation effect is good; Finally, it has good fire and seismic performance. 3. Prefabricated building construction technology.

The prefabricated building has the characteristics of redundant assembly, industrialization, standardization and integrated decoration. 4. Construction and assembly. A large number of prefabricated buildings are produced and processed by the factory, and the decoration can be completed in the factory with the main construction.

1. Diversified functions.

Through a large number of on-site assembly operations, the on-site cast-in-place operations are greatly reduced, which can significantly improve labor productivity. From a functional point of view, first of all, the exterior wall of the prefabricated building is designed with the function of thermal insulation, which can make residents feel warm in winter and cool in summer.

2. Construction and assembly.

A large number of components of the prefabricated building are produced and processed by the factory, and the integrated design and construction procedures of civil construction and decoration can be completed in the factory with the main construction, which not only ensures the quality of decoration, but also accelerates the overall progress of the project.

Because the weight of the prefabricated building is lighter than the traditional building, as long as the basic structural drawings are drawn, the construction can be carried out directly on the construction site, because its construction speed is very fast, so the work efficiency is also improved a lot.

3. Diversified design.

The prefabricated building is more in line with the requirements of green buildings, and the standardization of design and the degree of informatization of management are higher, and with the digital management of the factory, the cost performance of the entire prefabricated building will be higher and higher.

And the current building is designed to be based on the fixed pattern in the room, and the overall use of the house is not very flexible, but the prefabricated building can avoid such shortcomings, and its main residence can be divided into sizes, and configured according to the requirements of the residents.

4. Prefabricated building construction technology.

Prefabricated building is the main form, product and carrier of building industrialization, with the characteristics of industrialization, assembly, standardization and integrated decoration, and is assembled by building parts, building components, structural components and mechanical and electrical equipment and other parts in a reliable connection mode of industrial building. Prefabricated concrete structure is the most important structural form of prefabricated buildings in China.

2. The prefabricated building construction is assembled, which ensures the quality of decoration and accelerates the progress of the project;

3. The prefabricated building has a diversified design, realizes digital management, and is more cost-effective.

It is conducive to the development of China's construction industrialization, improve production efficiency and save energy, develop green buildings, and is conducive to improving and ensuring the quality of construction projects. Compared with the cast-in-place construction method, the prefabricated PC structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment, including reducing noise, preventing dust, reducing environmental pollution, clean transportation, reducing site interference, saving water, electricity, materials and other resources and energy, and following the principle of sustainable development.

1.The building parts are produced and processed by the workshop, and the types of components are: exterior wall panels, interior wall panels, laminated panels, balconies, air conditioning panels, stairs, prefabricated beams and columns, etc.

2.A large number of assembly operations on site are greatly reduced compared to the original cast-in-place operations.

3.The integrated design and construction of architecture and decoration are adopted, and the ideal state is that the decoration can be carried out simultaneously with the main construction.

4.The standardization of design and the informatization of management, the more standard the components, the higher the production efficiency, the corresponding component cost will decrease, and with the digital management of the factory, the cost performance of the entire prefabricated building will be higher and higher.

5.Comply with the requirements of green buildings.

Since 2015, the prefabricated building plan has been intensively introduced, and the "Evaluation Standards for Industrialized Buildings" was issued at the end of 2015, and it was decided to comprehensively promote prefabricated buildings in the country in 2016 and made breakthroughs;

On November 14, 2015, the Ministry of Housing and Urban-Rural Development issued the "Outline for the Modernization of the Construction Industry", which plans to account for more than 20% of new buildings by 2020 and more than 50% of new buildings by 2025;

On February 22, 2016, the "Guiding Opinions on Vigorously Developing Prefabricated Buildings" was promulgated, which requires the development of prefabricated concrete structures, steel structures and modern wood structures and other prefabricated buildings according to local conditions, and strives to use about 10 years to make prefabricated buildings account for 30% of the new construction area;

On March 5, 2016, the first work report proposed to vigorously develop steel structures and prefabricated buildings, and improve the standards and quality of construction projects;

On July 5, 2016, the Ministry of Housing and Urban-Rural Development issued the "List of Prefabricated Building Technology Demonstration Projects of the Ministry of Housing and Urban-Rural Development in 2016 Science and Technology Project Plan", and announced the list of prefabricated building technology demonstration projects for the construction of science and technology projects in 2016; On September 14, 2016, an executive meeting was held, proposing to vigorously develop prefabricated buildings and promote the adjustment and upgrading of industrial structure;

On September 27, 2016, the "Guiding Opinions of the General Office on Vigorously Developing Prefabricated Buildings" was promulgated, which clarified the key areas of vigorously developing prefabricated buildings and steel structures, the proportion of prefabricated buildings in the future, and the key development cities.

1.The construction speed is fast and the on-site operation is less; 2.The construction quality is stable, controllable and high-quality; 3.

Most of the components are produced in factories, and the construction environment has been greatly improved; 4.High degree of mechanization and automation, and improved working conditions; 5.It is easy to set up shock absorption and isolation devices, and the seismic resistance is improved; 6.

Energy conservation and environmental protection, save a lot of resources and energy, reduce construction waste, and save costs;

The amount of formwork on the construction site can be reduced by more than 85%; The amount of on-site scaffolding is reduced by more than 50%; The amount of plastering work is saved by more than 50%; Save more than 60% of water and reduce sewage by more than 50%; Save more than 30% of electricity, reduce the garbage on the construction site by more than 80%, and shorten the construction period by more than 50%; Labor is reduced by more than 40%;

1. Various design forms.

At present, there is a disconnect between residential design and housing demand, with many load-bearing walls, small studios, and dead separation, and the space in the house cannot be flexibly divided. And prefabricated houses"One of the core problems of flexible partitioning of large bays and flexible partitions is to have supporting lightweight partition walls, and light steel keels with gypsum board or other light boards are the best materials for partition walls and ceilings.

2. Functional modernization.

1) Energy saving: The exterior wall is equipped with an insulation layer, which can greatly reduce the energy consumption of heating in winter and air conditioning in summer;

2) Sound insulation: improve the sealing function of walls, doors and windows, and the insulation material has the function of sound absorption to make the room have a quiet environment and avoid the interference of external noise;

3) Fire prevention: use non-combustible or flame-retardant materials"prevent the spread or spread of fire;

4) Seismic resistance: a large number of lightweight materials are used to reduce the weight of the building and increase the flexible connection of the prefabricated type;

3. Unified manufacturing standards.

If the exterior surface of a traditional building relies on on-site construction to make a variety of beautiful patterns, it is very difficult to paint the color paint without color difference and without fading for a long time. But prefabricated building exterior wall panels can easily do this. In addition, the performance of materials can be precisely controlled at any time during the production process of the factory.

4. Time optimization.

The biggest advantage of prefabricated buildings is that they shorten the time of on-site construction and have higher feasibility of construction period. Prefabricated construction projects save time because factory fabrication and on-site construction can be carried out at the same time. Prefabricated foundations are rarely used in construction work, so the plant processes production structures, structural elements, service systems and interior integration modules at the same time as the foundation is built on site.

5. Technology sustainability.

Although the use of integrated components has long been on the agenda of designers and technologists in the construction process, there is no overlap between the theoretical system of prefabricated construction and the theoretical system of environmental protection. Today, people are aware of the serious environmental damage caused by construction waste. Cutting and mixing processes in processes such as woodworking, bricklaying, painting and decoration also generate excess waste due to the absence of an integrated assembly process, which is a significant share of waste generated during construction.
