Collection of Atlases for Prefabricated Floor Slabs in Buildings
The atlases related to prefabricated floor slabs in buildings mainly include the '14G443 High-Definition Atlas of Prefabricated Ribbed Base Plate Concrete Composite Floor Slabs' and the 'Xiang 2021G301 Atlas'. Here is a detailed introduction to these two atlases:
'14G443 High-Definition Atlas of Prefabricated Ribbed Base Plate Concrete Composite Floor Slabs': This atlas focuses on the specific type of prefabricated ribbed base plate concrete composite floor slabs, presented in a high-definition format. It provides clear and accurate graphical information for relevant engineering and technical personnel. The prefabricated ribbed base plate concrete composite floor slab combines the advantages of prefabricated components and cast-in-place concrete, offering high structural performance and construction efficiency. The atlas covers detailed information on the design, construction, and installation of this type of floor slab, helping to standardize and guide the design and construction of floor slabs in actual projects, ensuring that project quality meets relevant standards and requirements.
'Xiang 2021G301 Atlas': This atlas was approved and issued by the Hunan Provincial Department of Housing and Urban-Rural Development and officially implemented on April 1, 2021. It specifically standardizes and guides prefabricated ribbed base plate concrete composite floor slabs (including concrete ribs, steel bar ribs, and steel pipe ribs). This atlas is applicable to floor slabs and roof slabs in areas with seismic fortification intensities ranging from 6 to 8 degrees, fully considering the seismic fortification requirements of different regions to ensure the safety and reliability of floor slabs under earthquake action. The atlas details specifications for base plate materials, with different specifications meeting the needs and design requirements of various projects. It specifies the grades of perforated steel bars, as the reasonable selection of steel bars is crucial for ensuring the structural strength of floor slabs. Additionally, it provides technical content such as detailed drawings of structural joints, which are key connection points between floor slabs and surrounding components. These detailed drawings offer accurate construction references for workers, preventing improper joint handling from affecting the overall performance of the floor slab.
