Stairway between the floors: types, design features

Since ancient times, people have built houses on several floors. An integral part of them are interstorey staircases.

The staircase in the house now plays not only a functional role, as it was before. It still performs an important design function, being one of the main decorations of the room.

Modern staircases are distinguished by their design features, materials of manufacture, types.

Variety of species

Staircase interstorey can be of several types:

• Modular, which consists of various elements. This type is distinguished by a small consumption of building materials, increased strength, and a long service life. You can choose different shapes and colors, panels and decorative elements.

• Screw, suitable for small areas. The disadvantages of such ladders are the complexity of manufacturing, and also the fact that it is impossible to lift large items on it and at the same time only one person can move around it.

• Marching, which can consist of a different number of marches (one, two, three or more). It is recommended to make an intermediate platform every 10 steps. Performed along the wall or as an independent element. It occupies a large area. Can be swivel and straight.

• Combined, connecting elements of different types. Have a complex design, which requires serious calculations for manufacturing. As a rule, they require a large area.

Design features

By its design, the staircase is divided into the following types:

• Bolted, which is fixed to the wall with the help of metal rods. In addition, for the strength of the structure no additional supports are needed. Due to this, the interstorey staircase looks airy and light. Despite this, the design is very durable.
• On the Kosovar (beams). Kosowers are installed from the bottom in the shape of the entire structure. Steps are attached to them. The beams can be either straight or curved.
• On the strings. Steps are attached from both sides to the beams. The design is fixed to the wall or fixed to special supports. The bowstring is most often made of metal or wood.
• On the casing, characteristic of spiral staircases.
• Attic, which, if necessary, can be folded or pulled out.
• Combined, including elements of different types.

Choice of materials

For the manufacture of stairs are suitable for almost all types of building materials:

• Concrete.
• Metal.
• Tree.
• Particleboard.
• Marble.
• Glass.

In many cases the materials are combined, which makes each individual staircase unique.

Intermediate staircase with your own hands

You can not only buy a staircase, but also make it yourself. To do this, you need to take into account the size and height of the room, the maximum load, how often it will be used, what additional functions it will carry. All this needs to be considered at the design stage of the building.

In the absence of experience, you should not choose complex and intricate designs of stairs. From materials it is best to prefer a tree. In this case, shortcomings during work can be hidden or corrected without significant problems. Another plus in favor of wood is light weight.

Construction begins with design and calculations. Particular attention is given to safety and comfort. For safety requirements, the staircase must necessarily have handrails. And the distance between the balusters should be such that the head of the child does not pass between them. The recommended height of the handrail is 90 cm.

The width of the steps is recommended not less than 25-30 cm, so that the foot is completely placed on them. The desired height is 20 cm. To calculate the number of steps, the floor area is divided by their width.

The angle of the stairs is 30-40 degrees, which provides convenience and safety of movement.

After manufacturing and installation, the interstorey staircase is covered with decorative and protective means, which makes it more attractive.
