Doing concrete stairs themselves: 6 benefits
Concrete staircase is almost indispensable element of private domaLestnitsa classified as architectural structure that meets the specific requirements of durability, reliability and safety standards. Also, the ladder should fit into the interior of the house. For ladder is best to choose high-quality materials, which ensure long life product. Builders with long experience argue that the most reliable and durable material for stairs is concrete. Concrete staircase has improved strength characteristics and properties.
Advantages of concrete stairs to a house or cottage
Reinforced concrete structures characterized by high strength, as well as easy to manufacture any formation. Stair construction of concrete perfectly endure all the hardships of operation. Such designs have the ability to install in inside homes and on the streets, even near water off the coast. Also, concrete stairs are considered the most ideal option when constructed central entrance. And good for the movement in the basement or attic. Also you can use for landscape design.
Many people prefer to choose the concrete stairs, as they are durable and beautiful
The main advantages of concrete ladders:
- No assembly concrete stairs not shaken under load due to the monolithic structure;
- Concrete steps relieve owners from unpleasant sounds of the violin;
- Concrete staircase structure can be formed in any style and form, ranging from simple to complex configurations propulsion;
- Easy and quick production;
- Fire properties;
- Concrete stairs make it possible to use different lining material to create a unique look and design.
Concrete ladders can be monolithic or undivided. Also available are options where stringers are installed with mounting zabezhnymi steps.
Design concrete staircase you can design your own, or seek help from a specialist. Modern designers are ready universal projects that fit in any living room.
Types of concrete stairs and the requirements of GOST
All ladders are divided into categories and types. Reinforced concrete stairs are different in type and design of the marches. Called flight of stairs attached to the load-bearing beams stairs. Marches located between platforms that perform the function of the compound marches and icing them in a ladder structure.
Platform - this alloy elements in bulk or frame structure, which are made separately from marches or may be with them in one piece, are usually made for stairs with rotation.
Before installing a staircase made of concrete, you need to properly perform all the calculations for its manufacture
Stair-concrete marches divided into 2 types:
- Monolithic type used in typical buildings and constitutes an integral unit.
- Prefabricated use to make stairways whose size is far from the standard (for example - 1300h350h50). Such structures fall into odnomarshevye, half-pace and mnogomarshevye types. Also, they can be straight, circular and rotary.
Basically, staircases may differ decorating, which has the function and aesthetic appearance. Also, concrete stair construction must meet certain technical requirements that must be considered in the production.
First of all, it's safety standards and aging heavy loads, in accordance with EU standards:
- The number of steps can be in the range 3-18 pcs .;
- march width should be no less than 900 mm;
- The height of the steps may be from 150-160 mm;
- Landings may be 2000 mm in length.
- The angle of inclination of concrete stairways shall be 25-40 degrees.
Manufacturers that produce ladders, first of all, take care about the convenience and security, for this reason, regulatory compliance - a prerequisite.
The main elements of a concrete reinforcement ladders and
Any ladders are the main elements of which are, in fact, is the whole structure.
Internal propulsion concrete stairs include the following elements:
- Reinforced concrete marches;
- The staging area;
- Floor area;
- Tread for a decorative finish.
If you have decided to independently produce and install the concrete stairs, then you need to prepare in advance for materials
All concrete elements for the manufacture of ladder are reinforcing process.
Reinforcement is carried out using:
- Rod-hot-rolled steel;
- Special wire;
- Wire reinforced thermo-mechanical way.
Each component is a very important part, which performs its function. Construction site combine together and provide a safe and convenient travel. sites length is double the average pitch of the adult person. In centimeters, this parameter corresponds to approximately 62 cm. The width equal to the width of the march. Guards must be installed securely and conveniently for travel. Protections can be made from any fabric that meets established standards.
The height of the guard should be at least 90 cm. Fencing material is best to choose for strength criteria.
The necessary calculation in terms of concrete stairs
To the ladder was comfortable and meet all safety standards before its manufacturer, should be carefully make a whole volume of payment transactions. Today, software developers offer an online calculator that, with the introduction of parameters, can make the necessary calculations. Experience and practice of construction workers shows that the best way to make payments on the already-proven technique.
Get a secure and modern staircase made of concrete can, if properly calculate all its parameters
In order to properly calculate the parameters of the staircase, you must know some indicators:
- span height;
- The basic design configuration;
- The width of the opening.
The formula for calculating the sum of these data:
- The number of steps;
- The angle of inclination of the march;
- The width of the march;
- The depth of the tread;
- The height of the riser.
When calculating the worth remembering that the most secure and comfortable stairs are considered a tread of 300 mm. To calculate the number of steps necessary to the difference in height between the floor is divided into the riser height indicators.
To determine the correct angle, you should use the model of a rectangular box. The legs of the triangle are considered conditional, as the treads and risers. Further it is necessary to divide the step height on its width, and determine the data values of Table tangent angle. The calculation must be carried out in accordance with the requirements, otherwise the staircase structure will uncomfortable, and quickly may fail.
Put the formwork for the concrete stairs of the home
Formwork is a form for casting concrete mortar for the production steps. For the stairs of concrete formwork is chosen, the frame is made of wood. Wood material is lightweight and durable, making the work in creating the formwork passes easily. If the shape of the staircase unusual, it is best to cut the formwork of durable materials, such as plywood. For fixing screws are used to advance to facilitate dismantling.
To enhance the formwork used metal bars or power in the form of angle.
Construction of concrete staircase, as a rule, begins with the installation of the formwork
Together with the form of mounted steel reinforcement for reinforcement. Porch can be made to its simplicity of construction. Formwork is mounted on a strictly engineered plan. The plan is constructed from pre-prepared calculations and carrying out the correct removal of the required size. Experts to help provide step by step instructions that will help the novice builder.
Instructions on the device casing:
- First of all, you need a pencil on plywood apply borders of the side walls of the porch.
- According to the drawing cut out parts of the walls.
- The walls are interconnected by transverse bars.
- Under the porch should dig a small hole where you want to pour gravel or sand and seal the roofing material.
- The next step should be the installation box, which must be attached to the vertical supports.
- Inside opalubnoy slab structures stacked metal mesh reinforcement.
When the formwork is securely fastened and secured, you can start pouring concrete.
We do steps Concrete stairs themselves
For the manufacture of concrete steps with his hands need a solution and specific knowledge and skills. manufacturing scheme is quite simple. After installation, the wooden formwork, concrete works are carried out on the steps of the production.
In order to manufacture the concrete steps for stairs, it is necessary to prepare in advance sand, cement and iron bar
To do this, prepare:
- Cement, which corresponds to the brand standards;
- The sand is coarse-grained;
- Crushed small size;
- Rod of iron fittings.
To create steps, it should be remembered that the formwork must be whole, without any cracks and gaps can be removable.
Fill should be careful to not collapsed under the pressure of the formwork construction.
To begin creating the future steps to be from the lower stage. When concrete work should not forget about the alignment of the solution, and you need to give it time to dry. When the concrete hardens, you can begin to dismantle the formwork. Dismounting is carried out using a hammer or screwdriver, depending on the mounting material.
The following process finishes. Concrete steps you can decorate a variety of materials, it all depends on the location of the stairs and owners preferences. Many designers trim level tiles, using beautiful carpets or special overhead wooden steps.
Independent repair of concrete steps of the staircase and the types of damage
Repairs to the concrete stairs required in rare cases. Most often, it is necessary to repair the very old stage where primarily damaged corners and edges. Restoration of steps carried out in several stages, depending on the damage.
The main damage to the concrete steps:
Cope with simple concrete staircase repair quite possibly yourself
After careful examination tested stage at which the damage detected and their causes, determines the type of repairs.
The works are as follows:
- Recovery corners;
- Removal of cracks and chips;
- Facing work.
Quite often, in order to re-set in concrete or the landing stage is selected marble chips. This new generation material, which allows you to recover ladders. This material has a plate form whose section is 3 mm.
Cantilever plate has different properties that enhance the wear resistance and durability of the concrete steps. Works of this material reminiscent of facing works.
Coatings marble chips give a beautiful view of the steps. Before restoration work should be prepared step. Help prepare resurfacing.

Any construction work requires specific knowledge, for this reason, you should not ignore the advice of experts. For making or repairing concrete stairs, carry out all the preparatory work - to prepare the base to calculate the correct weight and proportions also consider what options will have future articles. The estimate is also a very important part of the work. It is not necessary when it is drawing to save on quality materials. The estimate is needed to determine exactly how much you need the solution and additional materials. For easy creation of ladder should adhere to the basic rules and parameters, which are set by GOST.
