WOODEN STAIRS
At the outset, I will mention stairs with wooden steps, whose cleanliness is maintained by abrasion-white, clean sand, which also reduces the risk of slipping. It is currently fashionable in the West to keep wood clean and preserved. Wood is flexible and these stairs are pleasant to walk on. The steps follow each step you take (like floor surfaces in modern sports halls). Inside the building, the stairs are not exposed to the weather, therefore their long service life is guaranteed. There are two types of danger with wooden stairs: fire and biological (wood infestation by fungi and insects), which a good designer must of course remember, to secure an escape route in case of fire and that wooden stairs in single-family houses are best secured, as much as possible. Usually, single-family houses are built without practical fire protection. Who still wants to build up with living quarters (rooms) cottage attics, this one has to take into account, that it will be required to secure the installed stairs and their surroundings. This is what impregnation preparations are used for, fireproof, which protect stairs and other wooden elements and their surroundings from biological pests and fire flames. The desired type of stairs in cottages is single-flight stairs. Straight steps are provided between the parallel side logs, through the cheeks and steps they form a compact whole. This way is possible, that the stairs as a whole are made and embedded in the place designated for them. A special feature of single-flight stairs is the installation of risers. These are perpendicular planks seated to the plane of the steps (between the cheeks), which close the visibility between the steps and additionally ensure their stiffening and stability of the entire structure. The problem with this design is this, that after a few years the stairs begin to creak and creak, but at the same time they can be easily built by any amateur carpenter as standard construction – typical.
The railing of the stairs is required, that it is firmly attached to the structure of the stairs or the wall of the building and that the openings between its supports are so narrow, so that the child cannot slide between them. Railings can be built in various forms, determined according to our taste, e.g. from steel pipes with a square cross-section through round and flat cross-sections to various cross-sections of wooden elements. The style and form of the railing must correspond to the structure of the stairs.
