Vertical Ladder Stair CAD Detail with Roof Slab Section and Plan

This vertical ladder stair CAD drawing presents a detailed construction layout showing ladder connection with the roof slab structure and waterproofing layers. The drawing illustrates the vertical ladder made of industrial steel tubes sized approximately 2.5 by 5 centimeters with step spacing around 31 centimeters. The plan and sectional elevation clearly show how the ladder is fixed to the structural slab and the surrounding concrete block support. Architects and civil engineers can study the layout to understand the ladder anchoring system, handrail curvature, and the structural interface between ladder frame and concrete slab. Dimension markings help builders verify ladder height, slab thickness, and support alignment required for safe roof access.
