Aluminum stairs: layouts and support structures

Depending on the building, facade type and situation, JOMY offers aluminium stairs in many specific configurations. Different support structures are also available to answer the project's needs in the best manners.

Spiral stairs are less suitable for evacuation and are therefore not discussed here. A spiral staircase is less ergonomic, increasing the risk of falling during evacuation.

In-line stairs

These JOMY escape stairs have all flights in one line. This is the simplest form of fire escape stairs.

These stairs can be installed hanging from the wall or be self-supporting.

These stairs take a lot of groundspace and / or wall space.

For this reason they are only used for lower heights at maximum 12 à 18 feet. Every x number of steps there is a resting platform needed. The number is depending on the local legislations and habits.

Crossed stairs

Crossed stairs are offered in two positions.

In the parallel layout, all flights are parallel to the wall. The staircase is composed of two crossed flights per story, one access landing per exit and one intermediate landing in between two stories. The stairs are always located at least 1m from all openings.

In the perpendicular layout, flights are perpendicular to the wall. The staircase is composed of two crossed flights per story, one access landing per exit, and one intermediate landing in between two stories. The intermediate landings can be braced to the wall to improve stability.

There are two types of landing available: rectangular and polygonal.

Crossed stairs with rectangular landings

A crossed staircase is composed of two crossed flights per story, one access landing per exit and one intermediate landing in between two stories. Both these landings have a rectangular shape and are made of hight quality lightweight aluminum.

Crossed stairs with polygonal balconies

A crossed staircase is composed of two crossed flights per story, one access polygonal landing per exit and one intermediate polygonal landing in between two stories. These landings have a polygonal shape and are also made of hight-quality lightweight aluminum. This stair variant is also known as an "Escadesign".

Rectangular stair layout

The stair flights are mounted in an rectangular floor - plan.

In between two flights, a landing is placed at each corner of the square. Each story has one access landing, three intermediate landings, and four flights.

These evacuation stairs are installed with its own base structure also made from high end aluminum. For high stairs their are some anchors to the wall for more stability side ways.

Other layouts

Other staircase layouts are available on request: either the typical "American-style" configuration or a combination of all possible configurations.

Support structures

Depending on the building, JOMY offers several stair configurations, determined by stair layout and support structure. Different support structures are available:

  • classic self-supporting;
  • suspended;
  • combined.
Self-supporting stairs

The staircase can be classic self-supporting and mounted on columns. This support structure can be used with all different stair layouts.

This means that the stairs are independent of the walls and that it has its own supporting structure composed of vertical aluminium beams.

Even with a self-supporting set-up a lot of times there are some connections to the wall to take on stormwinds from the side.

This will be calculated by the engineers from JOMY so you will have a save and sturdy staircase.

Suspended stairs

The use of lightweight aluminum offers the possibility for a suspended support structure. If all stair elements remain relatively close to the façade, the stairs can be suspended from the façade by mounting on brackets.

In-line stairs and crossed stairs that are parallel to the façade can also have a suspended support structure.

A lot of times a mixture of selfsupporting and hanging structure will be used.
