Centre Spine Staircases
When looking to conserve space and not impact the walls of a structure, using a central column type of stairs can work well. The column can support a spiral staircase, a helix-type, a curved, a double helix, and any other form of rotational stairs. They all have one thing in common: moving about a central axis, and this is where the central column provides the support. If you have an older building, the walls may not have sufficient strength to carry the loads associated with stairs.
By using a central column, it takes the entire load. Now, this does mean that you need to have the column well designed, and it has to connect to the floor or foundation solidly. A further issue to consider is what is known as shear stress. The column is typically bolted to the floor; as people climb up and down the stairs, they will tend to shakes side to side. This motion will cause the column to do the same, and this will create the shearing affect on the bolts; if they’re not strong enough to resist it, the bolts will snap.
Don’t you worry about that; let us take the stress and you will have a professionally designed and built staircase around a central column.So, the design for any column stairs should be handled by a qualified architect or engineer. Also, they can evaluate the flooring, ceiling and/or foundation to insure all of them are capable of supporting the stairs. That is what you will get with us. Another plus to the central column form of stairs is that they are very decorative; so they tend to beautify a building, and add to its value.
