Structural engineering drawing for a residential roof formwork system at elevation 75284. Features a combination of precast concrete slabs (LT/LP 12+4cm and 20+5cm thickness) with detailed reinforcement specifications. This plan shows beam layouts with varying dimensions (14x25cm to 19x80cm), column positions, and slab distribution (L1-L11). Includes comprehensive technical notes on installation requirements, loading calculations, and concrete specifications (C35 grade with <0.6 water/cement ratio). Notable details include:
Key Specifications:
– Permanent load: 100 kgf/m²
– Accidental load: 100 kgf/m²
– Total design load: 200-745 kgf/m² (varies by area)
– Concrete class: C35 with minimum elasticity modulus >33GPa
– Environmental aggressiveness class: II
The drawing provides sectional details of slab reinforcement (positive and negative), wall concrete forms, and installation methodology for precast panels. Includes specific spacer requirements for maintaining proper concrete cover and reinforcement positioning.
