Atlas of Concrete Prefabricated Building Components
Currently, there are two representative works in the atlas of concrete prefabricated building components:
National Building Standard Design Atlas (13SG364): Prefabricated Fair-faced Concrete Bleacher Panels This atlas is jointly edited by the China Institute of Building Standard Design and Research and Beijing Prefabricated Building Engineering Research Institute Co., Ltd., and was published by China Planning Press in 2013. Its core content focuses on the design and construction of prefabricated fair-faced concrete bleacher panels, with a clear scope of application for sports venues and similar buildings with a seismic fortification intensity of no more than 8 degrees. The atlas systematically presents the design details of various component types, including KTA bleacher panels, KTB bleacher panels, KTC flat panels, and steps, through template drawings, reinforcement drawings, and connection detail drawings. Among them, the reinforcement selection table provides standardized references for the reinforcement configuration of different components, while the connection detail drawings clarify the connection methods and node treatments between components, ensuring structural safety and construction convenience. Additionally, the atlas includes instructions on manufacturing and construction processes, covering key aspects such as material selection, pouring techniques, and curing requirements, providing comprehensive technical guidance for engineering practice. The design is strictly based on technical standards such as the Code for Design of Concrete Structures, ensuring the scientificity and authority of the atlas.
Chongqing Engineering Construction Standard Design djbt50-xxx Atlas of Standardized Prefabricated Components for Prefabricated Concrete Public Buildings: Design Dimensions and Connection Details This atlas was approved by the Chongqing Housing and Urban-Rural Development Commission and officially came into effect in 2025. Its content focuses on the design of standardized prefabricated components for prefabricated concrete public buildings, covering public building primary and secondary beam schemes (truss reinforcement composite slabs, steel tube truss composite slabs), non-secondary beam schemes (steel tube truss composite slabs, prestressed hollow slabs), and standardized nodes. The atlas provides standardized solutions for the prefabricated construction of public buildings through systematic design dimensions and connection detail drawings. Among them, the primary and secondary beam schemes achieve a balance between structural loading and construction efficiency through the combination of truss reinforcement or steel tube trusses with composite slabs; the non-secondary beam schemes further simplify the structural system through components such as prestressed hollow slabs. The design of standardized nodes unifies the connection methods between components, reducing construction difficulty and improving project quality. The release of this atlas marks a significant step forward for Chongqing in the field of prefabricated building standardization, providing strong support for the development of regional building industrialization.
