Collection of National Standard Atlases for Prefabricated Housing

Here are some introductions to national standard atlases related to prefabricated housing:

1. Atlas 14G443 'Prefabricated Ribbed Base Plate Concrete Composite Floor Slab'
This atlas is applicable to floor and roof slab projects with a seismic fortification intensity of 6 to 8 degrees and a concrete environmental category of Class I. Its core content revolves around the composite slab technology using prefabricated prestressed ribbed plates as base plates, including the formwork and reinforcement design of the prefabricated ribbed base plates, as well as the structural performance testing methods for the base plates. This technology enhances the overall performance and construction efficiency of the floor slabs through a combination of prefabrication and cast-in-place methods, making it particularly suitable for construction projects with high requirements for seismic resistance and durability.

2. Atlas 16G906 'Illustrated Construction Process for Prefabricated Concrete Shear Wall Structure Residential Buildings'
This atlas focuses on the construction of prefabricated concrete shear wall structure residential buildings where vertical reinforcement of prefabricated components is connected using grout sleeves. The content covers key aspects such as system composition, overall construction process, component stacking and finished product protection, lifting and installation processes, cast-in-place joint treatment, and waterproof joint design for exterior wall panels. Through a combination of illustrations and text, the atlas systematically explains the technical key points throughout the entire process from component production to on-site construction, providing detailed guidance for standardized construction of prefabricated residential buildings.

3. Atlas 13G440 'Large-Span Prestressed Hollow Slabs (Span Range: 4.2m to 18.0m)'
This atlas is applicable to concrete hollow slabs produced using the pre-tensioned long-line bed slow-release process, with environmental categories covering Class I and Class IIa industrial and civil buildings, and a seismic fortification intensity not exceeding 8 degrees or in non-seismic areas. The atlas provides detailed explanations of the span range, production process, and applicable scenarios of the hollow slabs, offering an economical and efficient prefabricated component solution for large-span building structures (such as factories, warehouses, and large public buildings).

4. Atlas 13SG905-1 'Illustrated Construction Process for Formwork Engineering in Building Construction Projects (2014 Combined Edition)'
This atlas targets multi-story and high-rise cast-in-place shear wall and tube structure projects constructed using all-steel large formwork. It introduces the terminology definitions, construction systems, and operational key points of all-steel large formwork. All-steel large formwork is characterized by high rigidity, a large number of turnover cycles, and high molding quality, making it suitable for high-rise building projects with high requirements for construction efficiency and concrete surface flatness. The atlas provides standardized references for the design and construction of formwork engineering.
