How to make sure that the ladder, the calculation of which you did, did not fail you?

The staircase is always a decorative element that allows you to give your home a unique design. Visit any museum or building that has preserved its interior since the time of the kings. The main staircases of the Hermitage have long blessed our eyes with their beauty and royalty. But we hardly need a ladder, the calculation of which is associated with such requirements for splendor and pomposity. Now it's more important to fit it into the interior.

When you start building a house, try to locate the future beauty at the project stage. The calculation of the steps, their height, width and quantity can be done a little later, when the line of the clean floor is designated. There are two ways to determine all missing staircase parameters. The first option allows you to calculate the required data by formulas, the second one is based on a graphical approach.

Making a calculation of the staircase in a house that has already been built is usually somewhat more complicated than at the design stage. Here it is necessary to take into account the situation. So, it can turn out not quite such a project as you would like to see. Lack of space can change the appearance of the stairs, you will have to choose from what can be installed on this site. So that it does not work out, give her enough space in advance.

Knowing where your ladder will stand, start calculating with the definition of its kind. If this is a single-ladder ladder, then the angle of inclination and the size of the future Kosourah are important here. The number of steps is considered from the main indicators. The height of the riser, based on the recommendations of various building codes, should not exceed 20 cm. The minimum size, less than 14 cm, is also undesirable.

Usually, the length of the step of a person of medium height is between 60 cm and 64 cm. The width of the step should completely place the foot. Doing it less than 20 cm is not recommended, it will create inconvenience when walking. The step height is determined by the convenience of lifting the leg, usually this value does not exceed half the length of the step. For the final calculation, you can take your sizes directly. Then you will get a ladder, the calculation of which will fully meet your optimal figures.

Having determined the location of the ladder and the height to which it should be lifted, we begin to calculate the remaining parameters. We measure by roulette the length of the platform, which you took under the stairs, then to use ordinary mathematics. Knowing the length of the march, we determine the number of steps, using the height of the riser 16 cm. We specify this figure using the available information. So that the ladder, the calculation of which we will produce, was convenient, we take as a basis the averaged quantities. The height of the finished product is 320 cm. The length of the opening, which we can take into account in the formula, is assumed equal to 350 cm. Now determine the number of steps: K = 320/16 = 20.

The first step is considered the floor line on the first floor, so we do not take it into account in these calculations. We get 19 steps. Now determine the length of Kosovra. For this we use the school formula of Pythagoras. We have two digits, it remains to determine the inclined. Having done a number of arithmetic operations, we get the estimated length equal to 472.4 cm. We take the length of the march equal to 475 cm.

The following action helps to calculate the width of the steps. According to our data, we have 25 cm. We check the results by formulas that provide safety and convenience. The results obtained do not fit into these formulas, so it is necessary to change them to meet all the requirements. This is the size of the riser, equal to 18 cm.

K = 320/18 = 18 - 1 = 17 steps.

L = 475/17 = 28 cm.

28 + 18 = 46 cm.

28 -18 = 10 cm.

Got a perfectly acceptable option, but you can still play, considering all the external factors.
