What is the thinking of prefabricated building design?

Prefabricated building refers to the transfer of a large number of on-site operations of traditional construction methods to the factory, where the building components and components (floors, wall panels, stairs, balconies, etc.) are processed in the factory, and transported to the construction site for reliable connection. way to assemble and install buildings on site. Prefabricated buildings mainly include prefabricated and assembled concrete structures, steel structures, and modern wooden structures. They adopt standardized design, factory production, assembly construction, information management, and intelligent applications. They are representatives of modern industrial production methods. In recent years, under the guidance of relevant policies, prefabricated buildings have ushered in a golden period of development.

According to statistics, in 2019, the new construction of prefabricated buildings nationwide was 420 million m2, an increase of 45% over 2018, accounting for about 13.4% of the new building area. In 2019, the newly constructed prefabricated buildings across the country increased by 45% compared with 2018 and 55% in the last four years. In general, prefabricated buildings have shown a good development trend in recent years, and play an important role in promoting the transformation and upgrading of the construction industry and promoting green development and high-quality development in the field of urban and rural construction.

The components of the prefabricated building arrive at the site after the completion of production and processing in the factory, which reduces some of the wet work on the site. Overlapping floors reduces the use of some formwork and supports.

The scaffolding used in traditional cast-in-place high-rise shear wall structure generally includes hanging scaffolding, climbing frame and so on. The suspended scaffolding must extend the steel beams from the floor, continue to install the scaffolding from the upper part of the steel beams, and fix it with the main body of the structure. The crawling project with holes in the shear wall is widely used in high-rise building projects, and the external crawling project depends on the structure. The exterior wall, with the improvement of the project progress, met the project requirements. Suspended scaffolding steel pipes and other components are used in a large amount, the shear wall opening size is large, and the climbing frame with high risk of blocking water leakage and seepage in the later stage is more economical to use in high-rise projects, and it is meaningless for structures with about ten floors.

The prefabricated building combined with the prefabricated exterior wall adopts the plug-in tripod construction, and the two-layer plug-in is reused, which minimizes the plug-in assembly and reduces the plug-in cost, and the reuse rate reaches more than 75%.
