Foundation plate: usually has a rectangular bottom, beveled with moderate slope, calculated to have a reasonable size. When designing the slab, the architects will balance it to best suit the overall construction.
Foundation bracing (ornamental momentum): has the effect of supporting the upper partition wall and reducing the settlement and deviation between the foundations in the building. The foundation bracing combined with the foundation beam to reduce the foundation eccentricity, it is necessary to calculate it as a beam in the frame structure.
Foundation neck: The size of the foundation neck can be the same as that of the ground floor column, but it is usually extended by 2.5cm on each side to increase the concrete layer to protect the reinforcement in the foundation neck.
Concrete lining layer: This layer is about 100 thick, 4×6 stone concrete or broken brick concrete, cement mortar grade 50÷100 has the effect of cleaning and flattening the foundation pit, preventing cement water loss and making formwork. concrete for pouring concrete foundation.
