Structural Slab Section Design with Polystyrene Block System

This structural section detail drawing presents a clear slab construction system prepared in AutoCAD format, focusing on a lightweight slab with polystyrene block infill. The section illustrates the arrangement of reinforced concrete ribs, polystyrene blocks, and the compression layer above. Accurate dimensions are shown for rib width, block spacing, slab depth, and overall section height, helping users understand load distribution and structural behavior. Welded wire mesh placement and concrete cover thickness are clearly indicated to support correct reinforcement positioning and construction accuracy. The drawing also explains material layering, including the compression layer, structural ribs, and void-forming polystyrene elements that reduce dead load while maintaining strength. Measurement references guide proper spacing and alignment across the slab span.
