Comprehensive Wall Partition System Details
This technical drawing presents a detailed legend of interior wall partition types for a commercial construction project, with specific focus on steel stud assemblies and their acoustic/fire ratings. The plan primarily illustrates seven different wall partition configurations (1a through 1g) with varying compositions of materials.
Key Partition Types:
– Type 1a: 5/8″ gypsum board + 3-5/8″ metal studs + 3-1/2″ insulation + 5/8″ gypsum board
– Type 1b: 5/8″ gypsum board + 2-1/2″ metal studs
– Type 1c: 5/8″ gypsum board + 3-5/8″ metal studs + 3-1/2″ insulation + 5/8″ plywood + 5/8″ gypsum board
– Type 1d: Multi-layer assembly with soundproofing (includes Sonopan panels)
– Type 1e: Double-layer fire-rated assembly with resilient bars
– Type 1f: 5/8″ gypsum board + 6″ metal studs + 6″ insulation + 5/8″ gypsum board
– Type 1g: Fire-rated assembly with complex layering
The drawing includes a comprehensive material legend that defines abbreviations such as CM (metal studs), G (gypsum board), L (sound insulation), BR (resilient bars), and PS (Sonopan acoustic panels). Additionally, it provides important construction notes regarding fire ratings (45 min and 1 hour), installation requirements, and plumbing considerations.
Notable specifications include:
1. Metal studs typically spaced at 16″ on center
2. Sound insulation requirements for plumbing conduits
3. Vertical expansion joints required every 9 meters
4. All partitions must extend from slab to slab or slab to deck
The document serves as a critical reference for contractors to ensure proper wall assembly installation that meets both acoustic isolation and fire protection requirements.
