How to make a spiral staircase to the second floor with their hands - on manufacturing instruction

are several engineering solutions that are used in the regeneration of such "non-standard" staircase, hence the difference in their titles - spiral, radial, round.Regardless of the performance, they are very popular with homeowners.Someone wants to make a way into the interior of the dwelling elegance element and in front of someone faced the problem of lift to the second floor after the building renovation (for example, construction of the attic space), if it was not provided for in the original draft.

There is no point in this article give any exact dimensions of all the elements of such structures.Although, if only because all the houses are different from each other - and the materials used in the construction and layout, and size of premises.If desired, you can find appropriate drawings, but the owner, who decided on their own to take the job (without the involvement of specialists) on the Internet, is able to calculate all himself.Suffice it to know all the features of this "design" and to remember the basics of geometry.

therefore stopped on the specifics of the construction of a spiral staircase, what needs to know any master.A specific size of its competent owner can identify himself.

design variant with a central pillar - the most budget.The construction of the stairs in the other versions (for example, mounting the steps to the handrail system) will cost much more.But given the complexity of installation, self mount such a structure that meets all the requirements of the operation and security, is unlikely to succeed.

Purpose

If the ladder to be used as an auxiliary, a spare or emergency, in order to save the useful area, you can choose a circular version.The radius must not be less than 1 m, or to use it would be extremely inconvenient.

If this is the only way to the top floor, it is desirable to mount a broad and shallow design, features which will not create any difficulties when moving on it of people of all ages (if you want to build a conventional wooden staircase - read).

place

arrangement There are 2 options - adjacently to the wall or "independent" installation in any part of the room, with a stand as a support (supporting member).

Ease of use and safety

On the one hand, excessive railing impede transport by a spiral staircase dimensional things (furniture items, bulky household appliances).At the same time handrails that are too low (especially the lack thereof), represent a danger for the kids, and for older people.If the old man suddenly dizzy, he should be able to immediately find a reliable and comfortable support for themselves.It is these factors should be given priority in the selection of a design solution.

to content

• requirements used almost all of what is used in the construction industry.But for private homes is hardly suitable, for example, concrete or marble staircase.Most commonly it is made from metal or wood.Many designs are carried out in the "complex" version, providing for the combination of different materials.For example, metal + plastic or wood.Often you can find and exclusive performance when the individual elements are made even from a glass (naturally durable).
• Given the specificity of construction wood should be well dried (humidity less than 10%).It is easy to imagine how the "lead" a ladder, if the demand is not met.By the way, not everyone knows that, and Sellers "modestly" silent.According to the rules, the wood moisture content of more than 20% in the construction of general use prohibited.

As for the metal, it is better if it will or "stainless steel", or steel with a surface coating.For example, chromium or zinc.

• material should optimally combine the qualities of strength and "compliance", since the individual structural elements in the process will have to bend.For the construction of spiral staircases recommended such woods as beech, oak, from the budget - larch, pine, ash, maple.

Features calculations

If ladder option involves the construction of the central support, it must ensure maximum stability of the whole structure.For her, used a variety of materials, but in homes, usually a wooden pole or metal pipe.It is necessary to correctly determine the place of its location, especially if you have a basement, since it must be securely fixed above and below.In addition, she has to "hold" a significant burden.Consequently, all of the features overlap (floor and ceiling in the room) should be considered.

Since we are talking about is a spiral staircase, then it means that it is carried out in a spiral ascent.Consequently, over our heads will always be an upper step.When designing the need to focus on the growth of a tall man, so he did not have to go up (down), discomfort (the need to bend your head).Therefore, the distance between the stages (vertical) is selected approximately 2 m width

By flown requirements for all types of ladders are approximately the same -. About 1 m Regardless of their construction, is the optimum value, providing the convenience of displacement..

For manufacturing steps using a solid material.But railings (railings) can be made from metal, wood (plywood) or combinations thereof.

optimum tread depth (the h1) - 25 to 35 cm, but in the part where the step is fixed on a support (central pillar or wall.) - Not less than 10 cm, in the central part - the order of 25. In this case, the riser height (h2) selected in the range of 15 - 20 cm

often possible to meet the following recommendation on the relationship of these parameters:

h1 + 2h2 = 65 cm

Although some experts recommend to spiral staircases risers, as such, do not install...It is believed that their absence makes lifting more comfortable, and the overall weight of the structure is reduced significantly.Plus - saving on materials.

When manufacturing curved elements (handrails, string) of solid wood is pre-soaked in boiling water.Once the material becomes malleable, it is bent in shape and is fixed in a position prior to final drying.

Notes calculations

• The optimum height of the railing so when they are a little above the waist man of medium height.
• Determination of the number of steps performed by dividing the height of the structure (from the floor to the top) on the riser option.Thus it is necessary to take into account the thickness of the material used.As a rule, it never obtained quotient as an integer.Therefore, the fraction will be rounded up.In this case, the distance from the lower level to the floor is somewhat reduced, but on the convenience of using a ladder is not reflected.

main recommendations for the production of a spiral staircase in the article stated.But her choice of a particular model, the reader, for you.
