How monolithic concrete stairs are made
Among the huge variety of stairs, concrete is in the lead due to its reliability and durability. They are most often found in civil and industrial construction. In the article we will consider the first option, after which you will be able to make them yourself.
General information
They have many advantages over other types of stairs:
- a variety of finishes;
- structural strength;
- resistance to fire;
- noiselessness;
- the possibility of creating an individual design.
The concrete staircase is absolutely not afraid of moisture, and also it is almost not affected by external factors due to steel reinforcement, which is used as the basis of the whole structure. Its installation can be made both outside and inside the building. It will perfectly fit into the interior of a private house, office space or cottage due to the variety of lining options and performance.
Tip: if you can not dismantle the reinforced concrete structure with conventional tools, you will be able to cut the concrete with diamond circles using professional equipment.
Choosing the right design
According to the method of manufacturing concrete stairs can be divided into several types.
Type of construction:
- screw, the price of which is more expensive;
- marching.
Monolithic конструкция (собрана из готовых элементов).
Depending on the installation location:
- outdoor;
- internal.
To choose the right structure, you first need to decide on the place of its installation:
| Screw | This is a common option in our time, due to its maximum compactness and convenience. Most often it is installed in rooms with limited space. It has a different design, due to which it will perfectly fit even into the most unusual interior. Perily for it are often made of solid wood or steel. However, there are exceptions when using metal fencing with durable glass inserts. |
| Monolithic | The ladder got its name due to the method of manufacturing, by pouring cement into specially prepared formwork. The finished product is installed directly at the place of operation. |
| March | It has many undeniable advantages over other stairs. The main thing is that it is easily manufactured and has a wide overview. And since the main staircase is considered one of the safest, it is installed in homes where children and the elderly live. Its only minus? these are big sizes. |
Outdoor staircase
The outer stairs are made from previously prepared reinforced concrete marches. In the installation process, the main role is played by the terrain on which the ladder is installed; it must have a certain slope.
The instruction recommends that before starting the laying of parts of the structure it is good to compact the soil with coarse rubble. To do this, you need to make a spade to the size of the tread plate and risers. It can have both a standard form and an individual one under the order.
Tip: first of all you need to pay attention to the quality of the materials from which the stairs are made. Since it will be installed on the street, it will naturally be exposed to many negative external factors.
Do it yourself
Unlike other types of ladders, which can be installed in finished form upon completion of construction, the technology of monolithic concrete stairs provides for the construction of the structure at the time of building construction.
To avoid unnecessary financial costs, self-manufacturing and installation must be approached with extreme caution, as this is a very laborious process. The technology itself has a huge number of nuances, with the strict observance of which many undesirable problems can be avoided.
Tip: Before the construction of the stairs, carry out a preliminary calculation that determines the appropriate height of the climb. It is especially important to take into account the thickness of the floor covering, which will increase their height during the sheathing of the steps.
Formwork creation
To create a beautiful and smooth design you need to create a solid formwork.
Use some recommendations:
- To prevent the cement from flowing out during production, use waterproof plywood for construction, which closely connect with planed boards.
- Make for the strength of the concrete product in the formwork frame. It consists of durable metal rods (reinforcement), welded to each other.
- Install special plates immediately before pouring the concrete, to which the rails will be further attached.
Advice: if it is necessary to make technological channels in reinforced concrete, diamond drilling of holes in concrete will help you with specially designed crowns.
Pouring concrete stairs
At first glance, after the complex assembly of the frame and formwork, the process of pouring may seem like a very trivial matter, however, everything is not so simple.
This stage is considered the most difficult to manufacture.
- The flight of stairs must be concreted all at once, starting from the bottom.. Before pouring, crushed stone for concrete must be poured, which will make the structure completely immovable and prevent the mortar from flowing out of the formwork.
- In the next step, compact the concrete mass.that is another important process, otherwise the strength and quality of the product can seriously suffer.
Tip: in order for concrete to have sufficient density it is recommended to use an electrical construction compactor.
In the absence of this tool, you can use any available tools. To fill a monolithic structure, you need concrete with a grade not lower than B15, and preferably B25 or B30.
- The last stage in the creation of a concrete staircase is facing. If the installation of the stairs is not in the room, it is desirable to sheathe tiles with a corrugated surface that prevents frost on the steps.
Conclusion
It is very difficult to imagine our life without stairs, so we are used to them. Of the various designs, stand alone are monolithic concrete, which can be screw and mid-flight. In this article, the stages of their creation were discussed in detail. The video in this article will help you find additional information on this topic.
