In recent years, with the increase in the number of construction projects in China and the expansion of construction scale, people's requirements for architectural design have become higher and higher. If traditional design concepts and methods continue to be used, the development of the construction industry will not be able to keep up with the development of the times. The construction of prefabricated buildings needs to be processed in the factory first, and then transported to the construction site for assembly. Such a construction mode can not only reduce the impact of the construction process on the surrounding environment, but also speed up the construction progress.
It shows the following four characteristics: first, the design of the prefabricated steel structure adds two design tasks on the basis of the traditional design process; 1. the design task of the processing drawing of the prefabricated components; 2. the preliminary technical planning and design task. The addition of these two design tasks significantly improves the comprehensiveness and refinement of the prefabricated building design process. Second, the design of prefabricated steel structure adopts a modular design approach. In this way, buildings, parts and components can be unified and improved the standardization of prefabricated buildings. Third, the design of prefabricated steel structure needs to be effectively coordinated with various component manufacturers to ensure the integration effect of construction organizations such as the main structure of the building and prefabricated components. Finally, the prefabricated design is the basis for the production of corresponding structural fittings, which can enrich the construction scheme of prefabricated assemblies without changing the assembly conditions, thereby reducing the investment cost of construction units.
Prefabricated steel structure building design should abide by the following two principles;
Principle of universality
Prefabricated steel structure building design needs to follow the principle of universality. First of all, all prefabricated steel structure building design needs to pay great attention to the preliminary planning work, strengthen the control of the types of prefabricated steel structure components, and ensure the characteristics of prefabricated steel structure buildings. Secondly, all prefabricated steel structure building design needs to strengthen the fire protection and waterproof design to ensure the practical function of the building structure.
Sustainability principle
Prefabricated steel structure building design needs to follow the principle of sustainability. First of all, it is necessary to reform the traditional extensive development mode, strengthen the effective use of various resources, and conform to the development trend of green building. Secondly, repeated use of steel, reduce energy consumption and cost consumption of enterprises, improve the economic benefits of enterprises.
This production mode has formed the characteristics of modeling simplicity, rapid ordering, production process, operation flow, rapid processing, prefabricated quality, etc., and is suitable for the prefabrication of tower steel structure, steel structure plant, warehouse, office building, equipment frame complete set of manufacturing and other deep processing prefabrication of most steel structures, which is the development trend and progress of prefabrication of steel structures in China.
