At present, most construction industries in China still use on-site construction for engineering operations. Different from the traditional construction method, fabricated Architectural research It has obvious advantages such as controllable construction period, low cost, green environmental protection and excellent project quality. Mastering the application of new assembly technology has become the future development and research direction of China's construction industry. The information model of new prefabricated buildings is built by BIM technology. From product design to production process to final on-site installation, we can make a good budget, understand the time cycle more comprehensively and intuitively, and all parts can be traced back to the factory.
1. Overview of relevant theories
1.1 Prefabricated buildings
Since the beginning of the 21st century, with the rapid development and transformation of science and technology, the national productivity has also been growing. The construction industry has been regarded as the pillar industry of the national economy and socio-economic development. Today, with the progress of science and technology, the construction industry will usher in a new spring. With the development of modern building technology and the arrival of information industrialization, developed countries have taken the lead in the development of prefabricated buildings. With the acceleration of industrialization, China should also take corresponding measures. Information construction is an inevitable trend of economic and social development today. At the same time, it is also an effective way to maintain China's socio-economic development and reduce urban housing shortage. It is the most favorable decision for national social and economic development to vigorously develop prefabricated buildings and new prefabricated building technologies and increase investment in the development of prefabricated building technologies. The building form and structural system of prefabricated buildings are as follows: the building form is multi-storey, including high-rise, multi-storey, single storey, etc. The structural system is mainly large rooms, but also traditional building steel structures and new prefabricated assembly structures; By changing the wall material from the original reinforced concrete to the composite wall, and changing the masonry method to the on-site assembly model, the weight of the material is greatly reduced.
1.2 Advantages and characteristics of prefabricated green buildings
Different from the traditional construction method, prefabricated buildings have unique charm, which is reflected in design, production and construction. Unique components can be designed according to different functions of the building. These components can be produced locally and transported to the site for installation. Different from the traditional cast-in-place concrete, the setting of concrete does not need to waste a lot of time and space, nor will it cause damage to the surrounding environment. In addition, prefabricated buildings have the characteristics of overall decoration. During construction, decoration is carried out at the same time, which saves a lot of construction period and reduces environmental pollution and noise pollution caused by decoration. It is a new mode of current green environmental protection construction. In the process of prefabrication, the most important thing is the planning and production of relevant components. Its development trend is to carry out detailed division of labor and product outsourcing for each part, process it in different regions, and finally deliver it to the main workshop for installation. The whole process includes parts design, raw material selection, parts production, installation, storage, distribution, after-sales maintenance and other links. The construction process of new prefabricated buildings is similar to that of the construction industry, including planning, production, transportation, storage, construction and maintenance.
conclusion
It can be seen that prefabrication Architectural research The 3D modeling function of BIM can accelerate the construction cycle and reduce the cost from design to production and installation. The whole project completion process from design to construction of the assembly building is more closely integrated. Respond to the national call, pursue the concept of low-carbon environmental protection, achieve energy conservation and emission reduction, and realize the role of industrial transformation. However, to find a balance between BIM and prefabricated parts, many people still need to work hard.
