How to build a ladder on the attic

An attic staircase on cows (boards with cutouts for steps) is considered a simple product, make it a lover with a small carpenter experience.

The simplest design of the attic staircase looks like a single span located along the wall. The material used is wooden boards. The strength of the stairs and reliability is determined by weight it can withstand. Permissible load - 2 tons minimum.

On the floor of the attic, take a hatch contours, whose width will determine the width of the steps (80-100 cm). Luke is recommended to make square. Cut out the circular saw.

Stretch the twine parallel to the wall from the cutting in the floor to the floor. Measure the distance between the cord and the ceiling. The minimum distance for a convenient passage is 2 m. Measure the tilt angle of the twine and determine the number of steps, as well as the size of building materials for them. The number and size of elements are related to proportions.

The recommended angle for the attic staircase is from 30 to 45 degrees, the steps are made with a width of 30 to 40 cm, the distance between the steps (the approaches size) is from 120 to 200 mm. For the approacon there are its own conditions: at the angle of inclination of the stairs from 33 to 37 degrees, its height is 160 cm, from 38 to 42 degrees - 180 mm, at 45 degrees - 200 mm.

Change the position of the cord until the desired number of steps and dimensions are obtained. To withstand the characteristics of the elements of the stairs in the mansion is difficult, but the retreat threatens inconvenience when walking. Apply on the wall the location of the cuts on the cosos, with the width of your widths of the steps. When calculating, keep in mind that the step should hang over the underlying to 4 cm.

For the manufacture of Kosomrov, two boards with a thickness of 5 cm are needed. The boards width should be such that after cutting the seats under the stage remained less than 15 cm of the body. For wide stairs, 3 Kouryra are needed - 2 along the edges of the steps, 1 in the middle.

Leave the building material in the room where the construction of the staircase is scheduled for several days. The boards will take final dimensions and shapes will be accompanied to humidity and temperature in the room.

From the ends of the board, cut the corners, which will allow the KOOPER to lie tightly to the floor and the ceiling beam. For fixing to the ceiling beam in the board, spikes are cut off, and in the beam - deepening. Follow the position of the bar, which will serve as a support of the staircase. In size, drink in the lower part of the groove crouter. It will serve as a landing site of the stairs on Bruke.

Fix the board to the wall, combining the upper part with the cord on the wall. Transfer tags for steps from the wall to the board. Sizes cut the teeth in the board. Use custom spaces as a layout and cut the second sample. Cut from the boards with a thickness of 2.5 ... 5 cm Steps in size defined in advance. The top face of the end of the stage protruding over the bottom step, round by the planer to prevent the brightness. Boosters and steps Profselume and skill.

Secure the timber to the semi in marking. Install the boosters with the bottom of the bar, and the top - spikes into the ceiling beam. Warred down first. Board to Lower Bruus Break Self-Sales, Spikes Top Mix with carpentry glue. Second Kosur exhibit strictly parallel to the first, using the construction level. In places of attachment, the ladder can be reinforced with metal corners. In 2-3 places of the booster boards, connect with metal studs.

Installation of steps Start from the bottom of the stairs. Join the joints with glue, the steps will fasten with self-draws to the Kosomes. The gap between the steps vertically close the opposites. They can be made of plywood, dimensions determine the place.

Side side of the ladder squeeze plywood. If the width of the staircase is less than 120 cm, make a railing railing with a height of 90 cm and adjusted vertically to the Kouner. Fix racks. Under the handrails, lock some narrow boards to the racks. After the end of the joiner's work, the stairs are painted.

The advantage of the independently made staircase before purchasing is that it takes into account the deviations and inaccuracies of the construction of the house. The shopping staircase may simply not become a regular place.
