Atlas of Prefabricated Components for House Cover Plates

The following is information on the atlas related to prefabricated components for house cover plates:

16G116 - 1: Selection Catalog of Prefabricated Components for Prefabricated Concrete Structures (Part 1) This atlas primarily focuses on the component design for prefabricated concrete shear wall structure residential buildings. Among the prefabricated components related to house cover plates, it includes truss reinforced concrete composite slabs (with a 60mm thick base slab). These composite slabs consist of a prefabricated base slab and a post-poured concrete layer, suitable for floor or roof systems. Their design must consider the overall stress requirements of the shear wall structure to ensure the reliability of connection nodes. The atlas specifies the size specifications, reinforcement methods, and collaborative working mechanisms with the post-poured layer of the prefabricated base slabs, providing a technical basis for the standardized design of prefabricated residential buildings.

Xiang 2021G301: Atlas of Composite Floor Slabs with Prefabricated Ribbed Base Slabs and Concrete This atlas focuses on the application of prefabricated prestressed concrete ribbed base slabs, suitable for floor and roof slabs in areas with seismic fortification intensities ranging from 6 to 8 degrees. Its core features include:

• Slab rib forms: Rectangular, T-shaped, or wedge-shaped ribs are used, with prestress applied through the pre-tensioning process to enhance the stiffness and crack resistance of the base slabs;
• Span range: The composite slabs have spans ranging from 3 to 9 meters, meeting the needs of large spaces;
• Post-poured layer requirements: The thickness of the post-poured layer should be no less than 1.3 times that of the prefabricated base slab to ensure the bond strength at the composite interface;
• Node details: Structural node designs such as perforated reinforcement connections and support anchoring are provided to ensure overall stress performance. This atlas offers lightweight, high-load-bearing solutions for roof systems, particularly suitable for areas with high seismic performance requirements.

Series of Atlases for Standard Prefabricated Concrete Components in Sichuan Prefabricated Residential Buildings The four atlases approved by Sichuan Province cover a variety of prefabricated components for cover plates:

• Standard base slabs for prestressed concrete steel tube truss composite slabs: The stiffness of the prefabricated base slabs is enhanced through steel tube trusses, suitable for large-span roofs;
• Standard base slabs for composite concrete slabs in prefabricated residential buildings (Part 1 and Part 2): Standardize the size, reinforcement, and post-poured layer processes of the base slabs to improve modular design levels;
• Standard stair slabs for prefabricated concrete stairs in prefabricated residential buildings: Clarify the prefabrication process and connection nodes of the stair slabs to ensure safety in use. This series of atlases promotes the industrial development of prefabricated buildings through standardized design, providing unified technical standards for the production and installation of prefabricated components for house cover plates.
