Platform

Definition

A platform is a horizontal landing in a stairway either at the end of a flight or between flights, either at floor level or between floors.

Purpose

Platforms provide resting areas, directional changes, and access points in stairways. They improve safety by offering a place to pause, especially in long stair flights, and facilitate changes in stair direction, making the structure more functional and accessible.

Examples of Use

• Staircases: Platforms are used in residential and commercial buildings to break up long flights of stairs.
• Fire Escapes: Providing landings on emergency exit staircases.
• Public Buildings: Used in multi-level public buildings like schools, hospitals, and malls for accessibility and ease of navigation.

Related Terms

• Landing: Another term for a platform in a stairway.
• Flight: A series of steps between floors or platforms.
• Balustrade: A railing supported by balusters, often found around stair platforms for safety.

Notes

• Design: Platforms must be designed to accommodate the expected foot traffic and meet building code requirements for safety.
• Dimensions: The size and placement of platforms are crucial for ensuring accessibility and comfort.
