Finished construction before finishing
It is better to plan the construction of the stairs in advance. Then, after arranging the room on the mezzanine, you will not face a problem
Oak, larch, pine wood is suitable as a material for this design and its decoration. The lower end of the kosour is attached to the floor, and
You will need:
- A set of tools for woodworking.
- A circular saw.
- Bar section 340
190 mm (kosour)
- Planed boards 600
250 fifty mm (number see drawing).
board 600 350 fifty mm (lower step).
- Beam 140
140 mm (base of the landing).
- Beam 110
110 mm (parapet post).
- Beam 90
0 mm (parapet handrails).
- Board 120
thirty mm (horizontal parapet rails and mounting brackets).
- Round timber with a diameter of 40
- Bolts diameter 10
mm with washers.
- Clear nail polish.
Before starting work, draw a projection of a staircase with a platform on the floor of the room. This life-size drawing will allow you to determine the dimensions and location of the stairs, as well as the number of steps. When calculating, take into account the length of the stairs, its slope and the most convenient interval between the steps
The elements shown in the drawing are transferred from paper to the appropriate lumber from which this structure will be built. Spikes and grooves, designed for attaching horizontal rails and railing posts, are drawn on a tree and sawn out.
To check and correct any inaccuracies, carry out a preliminary control assembly of the entire structure. After you assemble the landing, secure the joints with pins or bolts.
In the support beam that supports the platform, installed in place, cut the grooves, taking into account the level of the floor. Then lift the platform and attach it to the beam with bolts crossing the spikes of the platform parts. Attention: for the assembly and installation of this structure, scaffolding or scaffolding and the help of a second person are required.
The only support of the stairs is the central kosour, made of timber with a section of 340
An inclined beam with triangular grooves should rest against the floor and landing. First, these places are marked.
In our case, the central stringer is made from a single bar. You can make a similar detail yourself by gluing two boards and putting them under a press. Then it is necessary to strengthen the connections with transverse wooden dowels or bolts. When joining the boards, make sure to alternate the direction of the wood fibers.
Then, with an electric saw or a hand saw, triangular fragments are very carefully cut out so as to maintain the parallelism of the floor surface and the kosour platforms on which the steps will be installed. Preliminarily, in the corner of each cut, it is necessary to drill holes with a diameter of 25
The landing parapet consists of three pillars reinforced with spikes and grooves. On the racks, handrails and lower horizontal bars are installed in the same way. Along the edge of the mezzanine are removable horizontal strips, held on pins inserted into the holes of wooden supports. The latter are mounted on vertical posts and thus are mounting brackets.
All parts are sanded with medium emery, and the corners are smoothed with fine sandpaper. Chamfers with recessed bolt heads are covered with synthetic mastic or wood putty of the same color as the main structure, and then the entire structure is covered with a layer of colorless varnish.
Under the three horizontal rungs of the landing, auxiliary decorative beams are bolted, the ends of which are cut at an angle of 45 degrees.
The railing necessary for safety is a round bar with a diameter of 40
In order for the structure to comply with safety standards, the distance between the handrail and the lower horizontal bar of the parapet should be no more than 18
