At arrangement of the house having two floors and more it is necessary to establish ladder designs between levels. The metal spiral staircase made with own hands can become not only convenient functional element of the dwelling, but also will give the chance to decorate interior, having given it identity and originality.
It is required to you
- - scheme of spiral staircase;
- - metal pipes;
- - sheets of metal;
- - metal corners;
- - fastening elements;
- - hacksaw;
- - angular grinder;
- - welding machine;
- - electrodes;
- - primer;
- - paint;
- - brush.
Instruction
1. Choose ladder design, convenient for you. Its steps can have support on the walls located on perimeter or lean on the central supporting pole. Fastening of steps can be miscellaneous also. Most often they are jammed in supporting pole, opirat on protection or on bent bowstrings. It is the best of all not to use the vertical element connecting the end of the lower step to the beginning of top in design. It is convenient for those who have the big size of leg.
2. Draw the scheme of ladder in all projections. Put down the necessary sizes of all design and its separate elements. It will allow not only to provide future type of ladder, but also will give the chance to calculate the need for materials. Very conveniently volume image of spiral staircase executed in the special computer program. Such 3D model can be provided visually in room interior.
3. Carrying out the drawing of ladder, take into account to feature of screw designs. The middle of step has to have width not less than 200 mm. Reliability of ladder is guaranteed if diameter of supporting pole is not less than 50 mm. Separate ladder rounds it is necessary to have taking into account human growth. It is the best of all if the distance to the following round is not less than two meters. Otherwise tall persons at rise on ladder should bend. Provide for ladder bent handrail from the thin pipe leaning on vertical racks.
4. Make all elements of which the design will consist, and then consistently collect ladder in installation site, having reliably fixed it at the lower basis and in upper part. Height of the central column has to correspond to distance between house levels. To it strictly perpendicularly and densely metal sleeves fasten, directly which steps join. For cutting of metal parts it is convenient to use the angular grinder. Connection of elements is carried out by means of welding and also on bolts.
5. After the end of mounting of spiral staircase make sure of its reliability. Process places of connections by the grinder and file to remove the acting metal and hangnails. Cover framework with primer, and then paint the color which is in harmony with other elements of decor of the room. Such processing will allow to save ladder from corrosion and will prolong the term of its service.
