DIY garden ladder

If we talk about the attractiveness and bright element of the interior, then competitors of the spiral staircase can hardly be found. With the right construction, it will last for many years. It can be made both from wood and from metal with forging elements. There are 4 main types of spiral staircases:

A construction with wedge-shaped steps, which with the narrow side rest on the supporting central column, and the wide side against the wall or a fabricated frame. In this case, spiral bowstrings are constructed on stringers.
A freestanding structure, remote from the walls with cantilevered steps on a monolithic pillar placed in the center.
Design without central support pillar. The steps are supported by curved bowstrings or stringers, which smoothly merge into the railing. This option is very beautiful and sophisticated. However, it is very difficult to manufacture.
Construction with a central support bar (asbestos-cement or steel pipe Ø50 mm can act as a support). This type of ladder is the most common.

DESIGN AND CALCULATION

As practice shows, the most convenient spiral staircases with a span of 0.8–0.9 m. As a result, the diameter of the entire staircase will reach up to 2 m, taking into account the central support post and railing. If we talk about the shape of the stairs, then it can be round, square, rectangular or oval.

Pay attention!

If the traffic intensity in your house is low, then the total diameter of the stairs is enough to make up to 1.5 m. In this case, the treads will have a width of up to 0.6 m.

It is also necessary to consider the ergonomics of the spiral staircase. The principle of the size and height of the steps is the same as on ordinary straight stairs, we have already talked about such measurements above. But there are some features, namely a comfortable lifting height for a person. For example, we suggest that you consider the option of a spiral staircase with a height of 3 m and a march width of 0.8 m.

Calculations are presented below:

The total diameter of the staircase with such dimensions is equal to twice the width of the march, and the thickness of the support post is 20 cm.As a result, we get the following - D = 0.8 × 2 + 0.20 = 1, 8 m. / Li>
The lifting radius is equal to half the width of the flight of the stairs and the support: Rn = 0.4 + 0.1 = 0.5 cm. / Li>
Now, dividing the length of the trajectory of movement by the depth of the tread, you can determine the number of steps in one loop: L = 2 π: 200 = 2 × 3.14 × 500: 200 = 17.2. As a result, there can be 17 steps in one turn of the flight of stairs.
It is also necessary to calculate the ergonomic step height. This must be done from the account so that a person at full height can move freely. Take, for example, a height of 1.8 m, add operational 20 to this value and divide by the number of steps in one loop. As a result, it turns out like this: h = 2000: 17 = 120 mm.

Pay attention!

If the spiral staircase has a height of 3 m, then to determine the number of steps, perform the following actions n = 3000: 120 = 25. The result is 25 steps, 12 cm high.

It is better not to install risers on a spiral staircase. This will increase the safety of the structure, and the foot will rest well on the step and will not slide off the step in a narrow place.
If the height of the passage is 2 m, then even a tall person can comfortably move up the stairs.
To install the support leg, choose a location that will support the weight of the entire structure and 2-3 people.

STEPS MAKING

You can ask the professionals for help, but keep in mind that they may not attach importance to minor defects during construction, which can subsequently lead to serious breakdowns and subsequent repairs. A self-made staircase to the second floor will give you several advantages:

the result will meet expectations;
will help save money and nerves;
a ladder made by yourself will become your pride.

If you are limited in funds for the purchase of materials, you can buy cheaper analogs: instead of wood, use chipboard, which can be varnished or painted.

Pay attention!

In pursuit of economy, quality can be overlooked. While a cheap wooden staircase can also last a long time, it will start to creak very soon. In order not to face this nuisance, the ladder must be assembled using silicone sealant, which cannot be done without preliminary painting of the parts.

In this article we will talk about how to make a staircase to the second floor with our own hands from wood and metal, as well as show photos and video instructions.

MATERIAL SELECTION

For the manufacture of an interfloor staircase, concrete with facing from tiles or marble, metal (a welding machine is required), as well as wood can be used. The last option is the most practical and convenient. The wooden structure is lightweight, easy to install and beautiful in appearance.

CONSTRUCTION

If there is a room with a ceiling height of 2.8 m, it is worth giving preference to straight structures, or with a 25% turn of the staircase. The staircase is made with a length of 80 cm.This option allows you to use the space under the stairs for storing things. It should be noted that there is also a minus: free space on the upper and lower floors will be significantly reduced.

To save precious square meters, a spiral staircase is ideal, but it also has some drawbacks:
