When building a house, we are often faced with the need to install the staircase leading to the upper floor.All measurements are calculated based on the altitude at which the necessary rise.This is the main value that affects all other characteristics.Counting stairs and landings at the stage of planning the house, you get a ladder, taking into account all your wishes.If the calculation started after the completion of construction of the house, it should be based on the available free space.So sometimes it happens when the new owners have decided to restructure the finished house.But the output can always be found, above all, to do all the calculations beforehand.You can invite professionals and explain to them your ideas.They estimate the situation and offer you possible solutions.
for two- or three-storey cottage, where the bedrooms are located on the upper floors, staircases and landings must be safe.The width of the stairs, the angle of ascent, railings - all chosen individually to the owners, and especially their children, there were no problems.If the size and layout of the house allow you to set odnomarshevuyu straight ladder, you must take this opportunity.
Calculate staircases whose dimensions are not yet known, can be taken on the basis of indicators.For example, the height of the march made up of the heights of risers, and its length is determined by adding the width of all levels.
Recommended dimensions set out in the SNIP, determine the height of the riser between 15 and 22 cm, and width comfortable level selected optimally in the range of 20 - 27 cm. Less than 15 cm step is not recommended.The only exceptions are winders, narrow edge of which can have a width of 100 mm.Tied to a height between floors, we expect stairs and landings based on pure sex.If the required value is 260 cm, height riser accept equal to 18 cm.
We count the number of steps:
By Art.= 260/18 = 14.4 pc.
receives approximately 15 pieces.Now play around with the figures.Accept stage width equal to 24 cm. As a result, we obtain the long march of 360 cm.
15 x 24 cm = 360 cm.
on the first indicator we see that the resulting figure is greater than our available space.Hence, it is necessary to make a new calculation using the other figures.
For example, we have an opening for the width of 180 cm, 200 cm in length. The recommended width of stairs - 90 cm, the size of the site is calculated from the width of the stairs.So, we have flights of stairs and landings with a width of 90 cm. The height of the staircase - 260 cm, the number of stages - 15, then we get two flights and a playground.To ease the task, marches do the same.Take them equal to 7 levels in each.
7 x 18 = 126 x 2 = 252 cm.
Missing height gets the first step or platform.With these dimensions we have a platform 90 cm x 90 cm when rotating the ladder 90 degrees and 90 cm x 180 cm, if the stairway is rotated 180 degrees.
If space is limited for the stairs, the device can be considered a spiral staircase or try to fit using winders.The device of wooden stairs in this case would be the most appropriate option.Winders allow to deploy the ladder to the desired degree, while not requiring large areas.The height of the riser remains the same, changing only the width of the stage, getting a trapezoidal shape.But thinking about the construction of his house, try to allocate the necessary space for future ladder to create a project that is convenient for all family members.
