Study Notes

Stairs

Stairs provide vertical circulation, moving people between floors.
Essential for accessibility in residential and commercial buildings.
Contribute to a building's overall design and aesthetics.

Stair Technical Terms

Tread: The horizontal part of a stair, typically 10-12 inches wide.
Riser: The vertical part of a stair, defining the height between steps.
Flight: A series of stairs between landings.
Landing: A flat platform between flights, allowing for changes in direction.
Headroom: The vertical clearance from the tread to the ceiling or overhead structure.
Nosing: The protruding edge of a tread, preventing slipping.
Stringer: The structural support holding treads and risers in place.

Stair Location Criteria

Stairs should be centrally located for easy access between floors.
They should not be obstructed by other building structures.

Types of Staircases and Suitability

Straight Staircase: Simple, direct vertical connection, suitable for spaces with limited space.
L-shaped (Quarter-turn): One 90-degree turn, typically featuring a landing, useful for homes/offices with limited floor space.
U-shaped (Half-turn): Two 90-degree turns, often with a landing in the middle, suitable for buildings with wider floor plans.
Spiral Staircase: Winds around a central axis, compact footprint, suitable for smaller spaces, such as lofts, towers, or smaller residential buildings.
Helical Staircase: Variation of spiral, smooth curved design, without a central pole, suitable for high-end residential or commercial buildings.
Floating Staircase: Treads are directly attached to a wall or beam, creating a floating appearance, ideal for modern minimalist designs.
Suspended Scaffolding: Suspended from a building by ropes/cables. Suitable for tall buildings and cleaning tasks.
Cantilever Scaffolding: Supported at one end, extending over an edge, suitable for overhanging or high areas.
Mobile Scaffolding: Mounted on wheels, useful in smaller spaces that need frequent repositioning.
Steel Scaffolding: Entirely made of steel, offering strength and durability, suitable for large construction projects.
Sundec Scaffolding: A scaffold suspended from a building's roof or balcony.
Frame Scaffolding Pre-fabricated frames connected to form a scaffold.

Painting and Coloring

Aesthetic Appeal: Color and finish customization enhances the appearance of walls, doors, windows, and furniture.
Protection: Protects surfaces from environmental factors like moisture, dust, and pollution.
Durability: Improves the lifespan of the underlying surface, prevents wear and tear, and extends the life of the surface.
Hygiene/Maintenance: Cleaner to clean surfaces.

Painting Types

Oil-based: Durable, glossy finish, good for wood, metal, but longer drying time with a strong odor.
Water-based (latex): Fast-drying, low odor, easy cleanup, common for interior walls and ceilings, but less durable than oil-based for high-traffic areas.
Enamel: Hard, glossy finish, good for metal and wood surfaces.
Primer: A preparatory coating to improve paint adhesion, seals/prepares surfaces, and enhances final finish.
Processes for Painting and Coloring: Includes cleaning, priming (if needed), and applying coats of paint using brushes or rollers.

Scaffolding

Purpose: Temporary structures crucial for supporting workers, supplies, and tools during construction, maintenance, or repair.
Essential for ensuring worker safety at high places.
Types:
- Tube and fitting scaffolding: Made of tubes and fittings, highly adaptable.
- Frame scaffolding: Pre-fabricated frames for assembly.
