Modern spiral staircases, distinguished by their special originality, also have a number of practical advantages and stand out noticeably against the background of traditional (marching) structures. Firstly, they take up much less space in the room, and secondly - for their construction you will need much less material than it consumes on an ordinary staircase.
When building a spiral staircase to the second floor, you will have to take into account a number of specific parameters such as:
Note that the construction of a ladder made of wood or metal is quite capable of even a beginner.
The operating experience of the screw structures suggests that the most convenient are the stairs with a span of about one meter. As a result, the diameter of the entire screw design (taking into account its placement around the central rack) should be about 2.3 - 2.4 meters.
Of particular interest are economical stair designs, the steps of which are fixed to the central rack and equipped spiral handrails mounted on balusters. In comparison with this option, the stairs with other types of support part (without a central pillar) are more complex in execution and will cost you much more.
As regards the shape of the screw structure, it does not have to be round in cross section. You can also select a polygon with sides adjacent directly to the walls. Steps can be mounted in the thickness of the wall with the help of special hinged fasteners (linings).
A conventional billet with a diameter of 50 millimeters with walls at least 4 mm thick is used as the central pillar of the metal structure. In the "wooden" version, the role of the central pillar is played by a column made of any kind of solid wood. In addition, popular materials such as concrete, brick, or natural stone can be used to equip the center pillar.
Handrails for handrails can be made of both glulam hardwood and ordinary metal. In the individual staircase structures all of the above materials may be present in combination. Like railings, gangways can be made of both wood and metal (even the option of making them from thick tempered glass is possible). For the manufacture of stairs suitable for any building materials, characterized by high strength.
