Do-it-yourself attic staircase for a private house

do-it-yourself attic staircase An attic staircase is a fairly simple structure that is easy to make on your own. This element can be of a solid type made of wood or metal, and it can also be lightweight and have a folding mechanism. In this case, the main thing is to draw up a drawing correctly, calculate important parameters, choose a staircase option for the attic and make it with your own hands..

What is an attic staircase

foldable loft ladder Before purchasing tools and materials for making an attic staircase, it is important to decide on the main types of this structure..

Today, the following types of stairs are produced on an industrial scale:

  • stationary;
  • portable;
  • foldable.

Each type of this product has its own advantages and disadvantages. It is necessary to make a choice, taking into account the area of ​​free space, as well as the possibility of self-creation of an attic staircase.

To create this structure, you will need the following set of tools:

  • roulette;
  • chisel;
  • hacksaw;
  • square;
  • screwdriver;
  • joiner’s glue;
  • polyurethane foam.

In addition, for work you will need a set of materials:

  • wooden blocks;
  • boards for racks (bowstrings) and steps;
  • plywood sheets;
  • articulated joints;
  • screws and bolts;
  • powerful hinges or piano designs;
  • shock absorbers.

The main parameters of the future design

parameters of a wooden staircaseThe main parameter that you need to pay attention to is the operating load that the staircase to the attic can withstand. In addition to the main weight of a person, an additional load is also taken into account. The optimal parameter is 150 kg. Also, to select the type of structure, it is necessary to take into account the parameters of the room in which the hatch will be equipped. For this, the height of the ceiling, its area and the place that the staircase will occupy is taken into account..

optimal dimensions of the attic staircaseIn addition, it is important to correctly determine the slope of the product, otherwise it will be inconvenient and even dangerous to climb along it. A suitable angle of inclination for an attic staircase is 45 degrees. This parameter directly depends on the height of the structure. Next, the parameters of the opening in the ceiling are calculated. It is not recommended to make the hatch too large. The width of the opening should be no more than 800 mm, and the length should be about 1200 mm.drawing and dimensions of the attic staircase made of metal

The dimensions of the attic staircase should be within 300 cm – exceeding this parameter will make the structure unsafe.

Manufacturing and installation of attic stairs

The foldable loft ladder is made of three separate sections. It is recommended to equip this structure with a special element that prevents slipping. Wooden products should have a corrugated surface, and metal products should have a notch. It is also extremely important to consider that it is necessary to provide a special mechanism that will allow the stairs to open and close smoothly. For this purpose, hinge joints are installed or conventional door hinges are used..

The process of phased manufacturing and installation of an attic staircase with a hatch is as follows.

Manufacturing of a box and a hatch

box makingFirst, a box is made in which the ladder will be placed when folded. The box is installed in the ceiling opening. To make it, you need a board equal in width to the attic floor. It needs to be processed and cut into elements. Next, the elements are glued with wood glue, and then twisted with self-tapping screws (diameter – 5).

hatch assemblyNow the hatch itself is being made. Take five bars (two shortened and three longer) for the frame. The size of the elements is 50×50 mm. One of the long ones is attached to the center of the frame for added rigidity. The junction points are treated with wood glue.

fastening plywoodNext, a sheet of plywood (approximately 8×10 mm) is placed on a frame made of bars. The plywood sheet is screwed to the parts using 50 mm self-tapping screws.

How the attic staircase is assembled

hole in the boards for fasteningTo assemble the stairs, boards are used that are designed for racks or bowstrings. The two boards must be fastened together with tape to accurately mark the length of the sections, holes for fasteners and grooves for steps. In two boards at the same time make a through hole in the form of a semicircle. Pivot joints are inserted into this hole..

sawing a boardThen a board with a hole is sawn in the center – these are the future racks (bowstrings) for the stairs. They are fastened with a mechanism that allows you to unfold the structure..

The next step is the markings for installing the steps. At this stage, they use malka.

In order for the markup to be symmetrical, it is better to make it on two boards bonded at once..

cuts in the boardsNow they make cuts, and then remove unnecessary parts with a chisel. Next, the boards for the steps are cut, mounted in grooves and fastened with wood glue.fastening steps with self-tapping screws

All steps must be secured with self-tapping screws. The remaining sections for the stairs are made in a similar way..

Proceed to fasten the hinge joints. You can buy a similar mechanism in any hardware or furniture store. But you can also make them yourself. The parts are installed on sections of the folding ladder that have been drilled in advance. The connecting bolt of the hinge mechanism is installed in the sawn groove. Hinges are installed in the same way in other sections of the ladder..

fastening of hingesNext, they move on to the fasteners that will hold and open the hatch. To do this, use the piano loops. They are installed on the edge of the box with a thin drill..piano hinge attachment

At this stage, the box must be securely “mounted” into the ceiling opening. It is attached to the walls of the fortified opening with nails or self-tapping screws. The resulting gaps are filled with polyurethane foam. Then hinges for the hatch are attached to the box and temporary diagonal bars are additionally installed.hatch hinges

A frame is installed on temporary stands, hinged hinges are mounted on its edge and screwed on. For the purpose of thermal insulation, any material is used for insulation and is sheathed inside the hatch. Then the frame must be additionally covered with a plywood sheet..

assembly processNow the hinge mechanism is installed, which will fix the lower part of the hatch. This may be the simplest option – two metal hinges fastened together.

Installation of an attic staircase

installation of an attic staircaseNext, proceed to the installation of the attic staircase and securing the upper section. To do this, use brackets that are screwed to the inner or outer side of the structure..

In conclusion, it is necessary to think over a mechanism that will reliably close the hatch and hold the attic staircase. As a temporary option, you can use a latch bar, which is screwed on with an ordinary self-tapping screw. If you choose a more complex option, in which this mechanism will be automated and the hatch will be held on the box. Additionally, the attic staircase is supplemented with shock absorbers (springs).

Mineral wool, foam rubber or expanded polystyrene can be used as an insulating material. And the hatch itself is sheathed with a sealed rubber sealant tape.
