Any owner of a two-story or higher private house is surely faced with the problem of installing a ladder. Temporary simple stairs have already been removed, it's time to start building a more perfect and convenient device for moving to the upper floors. Some order concrete structures, but many people like more aesthetic wooden products. They look more comfortable and natural. How difficult is a simple wooden staircase , can you do it yourself? Of course, you can use the services of a specialized firm, but you want to try to make it from the tree yourself. If you know how to use a carpenter's tool, then let's get down to business.
First it is necessary to determine the type of staircase:
- one-masted with a landing;
- two-marsh;
- spiral;
- staircase with staggered steps.
In addition, the following types of steps are distinguished:
- fixed in the supporting wall;
- attached to the wall with a crown;
- installed on the kosoura (special bearing beam);
- installed on two Kosoworks.
Types of stair flights:
- the easiest way is a direct march;
- if the height of the building is large, and the place does not allow for a direct march, then the L-shaped ladder with a turn of 90 ° is performed;
- The most difficult way is to build a U-shaped ladder with a platform and turn all 180 °.
The device of a wooden ladder and its assembly by own hands
- You will never build a ladder without preliminary calculations and a competent drawing. What dimensions do you need to know in order to start computing:
- height of the ceiling along with the thickness of the opening (H);
- clean ceiling height (h);
- width of the ceiling aperture (A);
- length of the ceiling aperture (B);
- the direction of climbing up the stairs.
The optimal inclination of the staircase is 30 ° -407deg; if you make it steeper, it will be hard for a person of old age to climb to the second floor, and it will be extremely inconvenient to drag out the furniture there. If you do not want to build a staircase, then use the pivoting steps. Best of all, when the ladder is not built in the middle of the room, but adjoins the wall - this greatly simplifies the fixing of the beams (Kosovars).
Step height take no more than 20 cm (the optimal size is from 16 to 18 cm), so that it corresponds to the step of the average person. By dividing the height of the march by this value and rounding it up to a larger integer, we get the required number of steps. The width of the board also plays a big role. The narrow step is inconvenient for walking, but the wide one also has a disadvantage - you will have to make big steps. Choose a size within 25-35 cm. The width of the march is no more than half a meter (starting from 1.2 m), usually it is a multiple of the width of the tread. The length of the ladder is easy to calculate, multiplying the width of the tread by the number of steps.
