Staircases

Staircases are seen as connectors between at least two different levels. Vertical risers and horizontal treads are connected to steps over a slope.

A staircase serves to provide horizontal and vertical access to buildings in order to negotiate height differences with the least possible exertion of force. Building law and safety matters, user concerns and identification, function and spatial experience, clarity and traffic flow as well as aesthetic concepts are determined very early in the course of a basic design brief.

Ramps with a lesser pitch (< 20°) could also be authorized in place of staircases (20 – 45°). Ramps are particularly suitable in buildings where the circulation routes need to be designed to be accessible for old people and those with disabilities. Other fixed access methods are stepladders (< 75°) und cat ladders (75 – 90°).

A staircase can normally be considered as a long-term investment. It needs to contribute to the aesthetic appearance of a space and of course be simultaneously functional and in accordance with the basic guide lines (DIN, GUV, requirements etc.). The surface treatments must at least meet the requirements at its installation location.

Staircases are divided into systems that are either necessary or unnecessary in accordance with building law, whereby a further subdivision differentiates between staircases and winding staircases. We plan, draw and realize your idea for an aesthetically pleasing and functional staircase together with you, our customer. Our comprehensive range of products extends from a fire escape on the outside of a building to various industrial staircases and elegant living room staircases.

 

Fire Escapes / Fire Exit Stairs

Physical structures must be built in such a way that outbreaks of fire and the spreading of fire and smoke are prevented and that it is possible, in the event of fire, to rescue people and animals and to carry out effective fire-fighting operations.

All usage units with habitable rooms on each level must be accessible via at least two escape routes that are independent from one another. The first escape route must lead via at least one required staircase in usage units that are not at ground level. The second escape route can be a place that is accessible by the fire brigade’s rescue equipment or a further, required staircase.

Fire exit stairs and fire ladders are alternative escape routes. They cannot be planned as necessary, vertical escape routes from the first. The ‘Working Paper on Escape Routes’ describes the individual requirements. Fire exit stairs in the form of an open, steel staircase can also serve as access routes for the fire brigade.

A second escape route via fire escapes and fire stairs is obligatory in many buildings to ensure that safe escape is possible in an emergency. The fire stairs could be the last resort in the event of fire. The second escape route should also enable access by the fire brigade.

Both clear legal provisions and the cooperation of customers and planners are responsible for compliance to these regulations. A steel staircase that is incorrectly installed or insufficiently maintained is just as insupportable as the complete failure to provide a required escape route.

With MEISER fire escapes you can be sure that you are well-equipped for any emergency.

 

 

Special Structures

By special structures we mean staircases that do not initially fit into one of our defined categories. In the end they are usually also spiral staircases or straight staircases but they do not always fulfil the purpose of a normal fire escape or industrial staircase.

Special structures, such as lookout towers for example, are always a special case, as with this project, where interaction is required between the staircase and the steel/wood structure. Close cooperation between the staircase manufacturer, third party trades and planners is essential for the success of the structure as a whole. Contact us with your specific requirements and place your trust in our strengths in the sectors of consultancy, planning and execution.

It is rare to use staircases that are supported only by the building and that take their inner stability from their own structure. This is, however, possible in the case of a reinforced concrete building because of its high load-bearing capacity.

Special structures can differ from the norm in widely varying ways. We are able to fulfil any kind of a special request thanks to our machinery and laser systems.

The method by which the spiral staircase is attached depends essentially on the diameter and the total height. The number of necessary connection points may vary, but the decisive point is whether it is possible to attach the staircase directly to the building. If the building type does not allow this, then brackets can be used to bridge the insulation and horizontal differences in height between the access height and the mounting point.

If an additional distance of 1.5 m between the staircase and the building is required for fire safety reasons, then this is solved by extending the landing in the access area and with pipe structures on the resting landings. The structural design of the necessary brackets is based on the transferred loads and the distance that needs to be covered.

We design the details as part of the construction documentation and submit it to you for approval.
