Double helix spiral staircase

Types of double helix spiral staircase

A double helix spiral staircase is a type of staircase that consists of two separate, but interconnecting, helical flights. They are parallel to each other and ascend in a spiral formation around the same central column. This type of staircase is usually found in buildings where two separate staircases are required for reasons of safety, such as in the case of fire codes, or for reasons of structural integrity. The double helix staircase allows for this requirement to be fulfilled while simultaneously saving on space.

The two separate flights of stairs are often interlaced, meaning that the steps of each flight alternate with one another. This interlacing provides an additional benefit in the form of increased stability as well as strength. The double helix staircase is a visually captivating structure that can be found in many renowned buildings across the globe, for example, in the case of the famous “Louvre” museum in Paris, France.

Double helix spiral staircases are aesthetically pleasing and provide a space-efficient means of traversing vertical distances. Their strength, stability, and visual allure make them a preferred choice for architects and builders in various settings.

Double helix spiral staircases come in different types, including:

• Intertwined Double Helix Stairs:

  These stairs are closely linked, with each pair of steps alternating. This design provides enhanced stability and makes the stairs look more unified. Intertwined double helix stairs are often used when a strong and steady stair structure is needed, like in important public buildings and luxurious private homes.

• Separate Double Helix Stairs:

  In this design, the two sets of stairs are not interlaced but run next to each other. While they are separate, they still spiral around the same central support. This type is frequently seen in fire escape routes, allowing two groups of people to exit a building swiftly and safely during emergencies.

• Floating Double Helix Stairs:

  These stairs seem to hang in the air without any visible support beneath them. This striking appearance is achieved by cleverly using hidden supports and strong materials. Floating double helix stairs are often found in modern building designs where aesthetics play a crucial role, allowing the stairs to become a stunning focal point.
