Staircase is always a decorative element that allows you to give the house its own unique design. Visit any museum or building that has retained its interior from the time of the kings. The front staircases of the Hermitage have long delighted our eyes with their beauty and roy alty. But we hardly need a staircase, the calculation of which is associated with such requirements for pomp and pomp. Now it is more important to fit it into the interior.
When starting to build a house, try to determine the location of the future beauty at the project stage. The calculation of the steps, their height, width and number can be done a little later, when the clean floor line is indicated. There are two ways to determine all missing stair parameters. The first option allows you to calculate the necessary data using formulas, the second one relies on a graphical approach.
Calculation of stairs in a house that has already been built is usually somewhat more difficult than at the design stage. Here it is necessary to take into account the situation. So, it may not turn out quite the project that you would like to see. Lack of space can change the lookstairs, you will have to choose from what can be installed on this site. To prevent this from happening, set aside enough space for her in advance.
Knowing where your staircase will stand, start the calculation by determining its type. If this is a single-flight, no-frills staircase, then the angle of inclination and the size of the future kosour 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. A minimum size of less than 14 cm is also undesirable.
Typically, the stride length of a person of average height is between 60 cm and 64 cm. The width of the step should completely fit the foot. Making it less than 20 cm is not recommended, it will create inconvenience when walking. The height of the step 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 dimensions directly. Then you will get a ladder, the calculation of which will fully correspond to your optimal numbers.
Having determined the location of the ladder and the height to which it must be raised, we begin to calculate the remaining parameters. We measure with a tape measure the length of the platform that you took under the stairs, so that later you can use the usual mathematics. Knowing the length of the march, we determine the number of steps using the riser height of 16 cm. We specify this figure using the available information. So, in order for the ladder, the calculation of which we will produce, to be convenient, we take the average values as a basis. Heightthe finished product is 320 cm. The length of the opening, which we can take into account in the formula, we will take equal to 350 cm. Now we determine the number of steps: K=320 / 16=20.
The floor line on the first floor is considered the first step, so we do not take it into account in these calculations. We get 19 steps. Now we determine the length of the kosour. To do this, we use the school formula of Pythagoras. We have two numbers, it remains to determine the oblique. Having done a series of arithmetic operations, we obtain an estimated length equal to 472.4 cm. We take the length of the march equal to 475 cm.
The following step helps to calculate the width of the steps. According to our data, we have 25 cm. We check the results using formulas that provide safety and convenience. The results obtained do not fit into these formulas, which means that it is necessary to change them in order to meet all the requirements. This will be 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.
We got a completely acceptable option, but you can still play, taking into account all external factors.
