Staircase to the attic
When building the stairs to the attic, I was guided by the basic principles: safety, convenience, functionality, cost-effectiveness in manufacturing and external attractiveness. In advance when designing the house provided for the location of marches. For the stairs, I chose the end of the corridor, provided for two marches upward with a turn of 180 degrees. And he designed the basement downstairs, and this is another two marches.The best fit is classical ( access) rotary design of the staircase with two straight marches, as it occupies a smaller area and through it you can bring the necessary furniture.The walls of the corridor are made of wooden structures on three sides,so I decided to make a staircase without balusters and disguise it as a cupboard, using the compartment mechanism as the door.Made a sketch, scribed a future ladder on the walls with a marker. Podstudenek was 20 cm high, and the level itself was 28 centimeters. When designing, I took into account the following: - the slope of the stairs should be minimal, for which the length of the march should be increased; - steps should be at least 30 centimeters deep and strictly equal in height so that they are easy to use and not be injured; - ensuring the reliability of the structure, fastenings, sufficient lighting; - performing a 90-cm-wide ladder, according to the recommended standards. I performed the lower march kosour from a bar 60 millimeters thick and 30-35 centimeters wide. I made a bowstring for a kosour from a corner, having drilled holes in it every 10 centimeters from both sides beforehand, for attaching the kosour to the wall. This corner in conjunction with other metal structures served as the supporting frame of the staircase.I also made the whole base of the upper march from a corner, which I sawed in advance with an angle grinder and cooked on the street. I used three old beds with an armor-clad mesh as a corner donor.pad, securing to the walls 40 millimeter corners, putting on them the old wooden door. From above, in addition to level the surface and give greater strength to the platform, fastened a chipboard sheet 90 centimeters wide. Later, the surface was faced with laminated parquet, and the transitions were covered with a decorative corner.The number of steps in the march accordingly, its march length will depend on the height of the second floor. The risers will give the staircase not only additional strength,but they will not allow fallen things to fall down and walk the flow of air from the basement or storeroom.
