Concrete staircase manufacturing: work order

If the newly created private house has more than one floor, then he will definitely need a staircase. It can be built from various materials, but the most durable and durable among them is concrete. In this article we will look at how to create such a product.

The advantages of concrete structures

The manufacture of concrete stairs allows to obtain a structure that has the following advantages:

• high strength - these structures are able to withstand significant changes in temperature and humidity, while not losing its durability. On average, their service life is more than 30 years;
• versatility - due to the variety of options for exterior decoration, these products can fit into almost any interior;
• ease of operation - care for such stairs is quite simple and does not require special procedures. Special measures will be required only for the repair of these structures. So, in order to remove small potholes, diamond drilling of holes in concrete is applied. The hole formed after it is sealed with cement mortar.

Types of concrete stairs

According to the method of manufacture

Monolithic and prefabricated structures are distinguished by this parameter.

Their main differences are as follows:

• monolithic structure - is made directly at the construction site. For this purpose, a frame is created, which is subsequently filled with a cement mixture;
• prefabricated building - it consists of ready-made concrete parts. They are brought to the construction site and mounted in a pre-prepared place.

By type of construction

There are two main types of stairs:

• screw products - they have the highest price. In addition, it is difficult for them to climb an elderly or sick person. In addition, they are almost impossible to use for lifting large-sized furniture. They have one virtue - it is an elegant appearance;

• marching products - consist of one or several marches, that is, rows consisting of steps connected to each other. This type is more common, since the production of stairs of concrete is much easier and costs much less than the creation of a screw design.

Procedure for creating a concrete staircase

Training

В первую очередь следует определиться с тем, какой вид сооружения вам подходит. Это устанавливается исходя из особенностей помещения и ваших предпочтений (читайте также статью «Железобетонные сваи: разновидности и назначение»).

It is also necessary to carry out a series of calculations to determine the specific values ​​of the parameters of the future structure and make its drawing. In particular, you need to calculate the total length and width of the future product, calculate the dimensions of the steps and risers. The calculations will help you determine the cost of manufacturing concrete stairs.

Tip! To facilitate the work should take advantage of ready-made drawings. If necessary, you can make some adjustments to them.

In addition, you need to immediately purchase the entire volume of the required material. Since we will consider the process of creating a monolithic staircase, you will need to buy not only cement and sand, but also boards and sheets of moisture resistant plywood.

They will be needed for the construction of formwork. You also have to purchase and fasteners, namely screws.

Formwork assembly

The direct production of monolithic concrete stairs begins with the assembly of formwork. It must be very durable and tough so that the product molded with it will be smooth and beautiful.

To prevent the concrete solution from flowing out of the formwork, it is made from sheets of waterproof plywood to which planed boards are attached. This is done with screws and a screwdriver.

Installing the reinforcement cage

The next stage of work is the installation of the reinforcement cage. It will become the steel base of the ladder and will save it from destruction. This element consists of metal rods bonded to each other using wire or welding.

The assembly instructions for the framework establish that this process begins with the installation of metal elements along the surface of the flight of stairs. After that, put the transverse pins and attached to the longitudinal details.

Next, near the edge of the formwork you need to install metal plates or wooden blanks. Subsequently, a railing will be attached to them.

Concrete Pouring

To complete the manufacture of concrete stairs with their own hands, it is necessary to carry out another key stage - this is pouring cement mortar. It is not as complex as the first two processes, but, nevertheless, it should be taken very carefully. The final result of this construction largely depends on its quality.

It is necessary to mix cement and sand in a ratio of 1: 3, then add 4 parts of rubble, the fraction of which is 10 to 20 millimeters. Then it remains only to add water and bring the mixture to the consistency of sour cream. Now you can go directly to the fill.

Tip! In order for a concrete structure to have the same strength throughout its length, it must be poured at a time. If you can not at the same time prepare the required amount of concrete, then you should buy it from a specialized company.

After pouring the mixture, it should be sealed to remove the air that may be in its thickness. To do this, use a building vibrator or a pin made of metal.

After the final drying of the composition of the formwork is removed. If on the resulting surface will be protruding irregularities, they are removed. For this purpose, the cutting of reinforced concrete with diamond circles is used.

Conclusion

Бетонные лестницы прочны, универсальны и просты в использовании. Они бывают монолитными или сборными, а также винтовыми или маршевыми (см.также статью «Железобетонные лестницы: особенности конструкции»).
