Define Staircase. Draft or Sketch to a suitable scale; plan and section of a Dog-Legged staircase for a floor height of 3000mm. The width of the flight is 1000mm. Having a riser of 120 mm & tread of 350 mm. 2. Different types of staircases and its components, with neat sketches. 3. Sketch the sectional view of the staircase. Indicate following elements in the sketch & define them: Baluster, handrail, newel post, soffit, tread, riser, nosing, waist slab, run, landing, headroom. 4. PVC as a building material with its advantages and disadvantages. 5. Define Door and Window. Enlist with schematic sketches of at least four types of each. 6. Materials used for manufacturing doors and windows. State advantages and disadvantages of each material. 7. Factors to be carried out while constructing a staircase. 8. Steel as a construction material. Explain its uses. Differentiate between Hard & Mild Steel. 9. Draw/ Sketch the Section and Elevation with detail, labeling of Double shutter adjustable louvered window. 10. Write down different factors to be considered for providing a window in a room? 11. Sketch & label following elements of door & door frame. Top Rail, Bottom Rail, Locks rail, Panels, Mullions, Hinges, jam, and threshold, lock stile & hinge stile.
Understand the Problem
The question consists of multiple parts asking for definitions, sketches, explanations, and comparisons related to architectural elements such as staircases, doors, and windows. Each part addresses specific attributes, types, and materials associated with these architectural features, requiring a blend of technical knowledge and visual representation.
Answer
A staircase bridges vertical distances using steps. A dog-legged staircase has two flights with a landing. For a 3000mm floor, use 25 risers (120mm each) and 24 treads (350mm each) totaling 8400mm run. Consider balusters, handrails, and clearance for safety.
A staircase is a structure designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps. A dog-legged staircase consists of two parallel flights of stairs with a landing in the middle, making a 180-degree turn. For a floor height of 3000mm, the number of risers required can be calculated by dividing the total height by the riser height. In this case: 3000mm / 120mm = 25 risers. Each tread is 350mm wide, so the total run (horizontal distance covered by the staircase) would be 24 treads at 350mm each, resulting in 8400mm. The detailed design should consider additional elements like balusters, handrails, and nosing. Ensure proper headroom clearance for comfort and safety.

More Information
Dog-legged staircases are popular due to their space-saving design, making them ideal for linking floors in smaller buildings. Proper design ensures safe and comfortable use.
Tips
A common mistake is miscalculating the number of risers or treads, leading to uneven steps. Ensure accurate measurements and calculations to avoid this.
