- materials used
is well known that modern spiral staircases, differing special originality,It has also a number of practical advantages and significantly stand out from the traditional (marching) designs.First, 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 ladder.
the other hand are considered much more difficult to design in performance.That's why during the construction of the spiral staircase with your hands you have to consider a number of specific parameters such as:
- -pillar structure;
- mounting method steps;
- configuration and the height of the handrail and balusters restrictive and more.
note that the construction of a spiral staircase made of wood or metal, are quite capable of even novice.It is only necessary to take into account all the nuances, which often have to deal in the manufacture of this original design
helical structures operating experience suggests that the most suitable are the stairs with a span of about one meter.As a result, the diameter of all helical structure (including its location around the central pillar) should be around 2.3 - 2.4 meters.
particular interest are economical ladders, steps which are fixed on the center rack and is equipped with a helical rails mounted on balusters.In comparison with this embodiment, other types of stairs with the supporting part (without central pillar) are more difficult to implement and will cost you much more expensive.
Regarding the form helical structure in the cross section, it does not necessarily have to be circular.You can select a polygon with the parties, immediately adjacent to the walls.Steps such ladders can be mounted in the thickness of the wall using special fasteners mounted (overlays).
as a central pillar of the metal structure using conventional tubular billet with a diameter of 50 mm with wall thickness of not less than 4 mm.The "wooden" performance playing the role of the central rack column, made of a variety of solid wood.In addition, for the resettlement of the central rack can be used popular materials such as concrete, brick or natural stone.
rails for the rail can be manufactured as a laminated hardwood and from ordinary metal.In some ladders all the above materials may be present in combination.Like the gangway can be made railing both wood and metal (even possible embodiment of manufacturing of thick tempered glass).In general, for the manufacture of a spiral staircase you can use any building materials, are characterized by high strength values.
order of arrangement of the helical structure
procedure of works on the arrangement of the spiral staircase in the general case might look like this:
- primarily made installation of centralrack, which subsequently fixed intermediate sleeve, together with the tread.
- After that the entire circumference of the structure being built evenly distributed level.
- Then you can go to the installation of support brackets installed consecutively on each of the rising stages.This last stage is rigidly fixed directly to the intermediate floor.
- At the final stage of installation of a spiral staircase, installing balusters and handrails rigid fixation.
Upon completion of all these operations, you get ready for use ladders.
For safety, durability and user-friendly design to take into account the following recommendations:
- recommend that you exclude from the design ladder optional item such as a substep.In this case, the foot will not slip down the stairs even in the most confined spaces.
- Lifting height ladder must allow free movement on it.
- rack should be placed on a support platform, capable of withstanding the total weight of structural elements and at least two people.At the same time fixing it in place should be as rigid.
- presence of overlap between adjacent steps will further strengthen the construction of facility under construction;to this end, it uses special brackets mounted between the front and rear edges of adjacent stages.
