Do-it-yourself concrete stairs and finishes

DIY concrete staircase

A staircase is a complex architectural structure, the list of requirements for which includes reliability, safety, aesthetics and comfort. The owners of the houses would like it to serve as long as possible and not require endless repairs. Therefore, among other materials used in the manufacture of stairs, most often use artificial stone – concrete. In terms of strength, artistic expressiveness, and operational longevity, there are no rivals for him yet, and the simplest concrete staircase is constructed with his own hands without any problems.

    DIY concrete staircase

    Concrete is a priority material for the construction of stairs, concrete stairs perfectly tolerate the entire range of external negative influences and intensive operation

    They are considered the best option for the construction of a central entrance group and to ensure movement to the basement or attic, they are used in landscape design. Besides:

    • monolithic design does not have elements shaky from dynamic loading;
    • users are not threatened with negative creaking sounds, even if the concrete stairs were finished with wood;
    • the embodiment of any ideas of architects is possible from elementary marching, more complex screw structures to complex composite configurations;
    • minimal risk of fire;
    • a lot of options for facing, compatibility and compatibility with any finishing and building materials.

    The construction can be entirely monolithic or solid can only be skewers, on which concrete steps for stairs without risers are hoisted after solidification of these frame elements. In the second case, the design is lighter, both in the technical and in the decorative sense, but installing it above the recreation area is not desirable due to the presence of gaps.

    Concrete stairs in private homes

    Only skewers intended for installation of steps on them can be poured out of concrete, so that the design is lighter, more elegant

    There is also a technical nuance: concrete stairs to the second floor, in the basement, in the attic, on the veranda can only be made at the facility. The work is carried out during the construction process and, unlike wooden counterparts, they cannot be installed after the completion of the interior decoration.

    Choosing the optimal design

    The whole process of erecting a staircase made of concrete is divided into three stages, these are:

    • formwork assembly – standard work for creating any concrete and reinforced concrete structures;
    • installation and knitting of fittings;
    • directly pouring concrete stairs.
    Spiral concrete stairs to the second floor

    The construction of a monolithic spiral staircase is best entrusted to professional builders

    The most difficult and time-consuming stage is the assembly of formwork. If it is planned to build a florid configuration, without the slightest doubt it will need to be entrusted to professionals. Formwork for stairs of non-standard geometry without significant experience in this matter is impossible to do.

    Concrete staircase casting: screw formwork

    Pouring a concrete staircase: the formwork for a screw structure is assembled from plywood elements or from a narrow edged board, the installation of numerous supports from a beam is mandatory

    The easiest way is to fill a single-flight staircase, placing it between two walls. Then the side elements of the formwork are not required, it is enough to draw a contour on the walls. The design of an elementary single-flight staircase can be varied with an interesting round shape of the lower step.

    More difficult to implement will be a single-march version with only one side resting on the wall, since it will be necessary to make the end element of the formwork and install supports to support it. It will be much more difficult to fill in the structure with two sides not adjacent to the walls, to build a two-marching version with downhill steps or with a landing. However, in general, simple geometry can be dealt with if desired, and the original finish of the concrete stairs with ceramics, wooden, nickel-plated, forged parts will make it unique.

    To fill the two-flight staircase, installation of the end elements of the formwork will be required

    Making a plan for future work

    Like any architectural and functional construction, a staircase requires preliminary design and calculations. A simple project must be done at least in the format of a sketch, hand-drawn.

    Standard sizes

    If you want to figure out how to make a concrete staircase, you should know that:

    • the width dictated by DIN 18065 and domestic SNiP should be 0.8-0.9 m;
    • step height standard 17 cm;
    • the height of the structure must take into account the power of the upper floor, including the height of the coated floor cake;
    • step width providing a comfortable step, 29-30 cm;
    • 30? is considered a convenient angle for tilting, but if necessary, reduce the area of ​​the structure, the angle can reach 45?.
    Concrete staircase to the second floor: calculation of the angle of inclination

    The optimal angle of inclination of the staircase is 30 degrees, with an increase in its size, the area of ​​the structure is reduced, at the same time, the risk of injuries increases, and the parameters of comfortable movement decrease

    Too steep stairs will increase the likelihood of injury. Technological limit of 45? also undesirable due to the inconvenience of moving. If you want to reduce the area in the plan, it is better to prefer the manufacture of concrete stairs with two or more spans or to install a screw structure.

    Important. The project must take into account the presence of fences, the installation of embedded parts for it should be provided for in the design.

    How to make a concrete staircase

    Calculation of the width and height of steps for the subsequent pouring of a concrete staircase with your own hands

    Base for construction

    Depending on the complexity, width and span, the weight of the concrete stairs will be from 1.5 to 2.5 tons. Therefore, before erection, it is necessary to think over the issues of the foundation device, the most common version of which are reinforced concrete beams and foundations. If the screed on the ground serves as the basis, the soil under it must be compacted and calculated so that the weight of the monolithic structure does not press on it with a force exceeding 1 kg / cm ?. It should be remembered that the decoration of the steps of a concrete staircase, for example, with natural stone, will significantly increase its weight. If the load exceeds the permissible value, it is better to sheathe wood.

    Important. A monolithic staircase made of concrete is not recommended to be supported on a screed with thermal insulation made of polystyrene. The section under the stairs will need to be dismantled, then fill in a special foundation.

    Phased construction of concrete stairs

    At the initial stage of formwork assembly, the following are used:

    • waterproof plywood (18-20 mm in a section) and / or edged board (3 cm);
    • building timber with a cross section up to 10 × 10 cm for racks and supports;
    • for forming curved surfaces plywood up to 9 mm or narrow edged board.

    Structural components of formwork for marching monolithic stairs

    There should be no gaps or gaps in the formwork. Connections are made using phosphated screws, you can install steel corners at the ends. After concrete hardening, all formwork elements can be removed without problems..

    Pouring concrete stairs with a width exceeding standard sizes

    If a concrete staircase is poured with a width exceeding the standard dimensions, the formwork is divided into distinctive segments

    In the finished formwork along the march, steel bars are laid and connected by reinforcing bars with transverse ties. Then, wooden plugs are installed under the embedded parts intended for the installation of the fence. Then pour concrete, the brand of which should be no lower in strength than B-15. You need to fill the whole march, starting from the lowest level.

    Pouring concrete stairs

    The concrete staircase begins to be poured from the bottom step; in one step, it is necessary to fill the entire march

    How can I finish a concrete staircase?

    In order to reduce the load on the base, the sheathing of a concrete staircase with wood is often preferred. Steps, balustrades and handrails can be made of wood. Nickel-plated fencing details, forged lattices, specific decor on the supporting posts are appropriate.

    Wood Concrete Stairs

    Concrete staircase in a private house: a spiral braid is cast from concrete, steps are lined with wood, handrails and balusters are made of wood

    Concrete is wonderfully in harmony with any material, therefore, in terms of finish, there are practically no restrictions.

    Porcelain stoneware

    Concrete staircase in a private house: steps made of porcelain stoneware, perfectly harmonizing with the main material of a monolithic design

    All elements can be completely lined with wood or tiled with risers or partially cover only the upper part.

    Wood concrete stairs

    Variant of finishing the monolithic staircase with wood: the steps and risers are completely sheathed, all the details of the fence are made of wood

    A variety of special effects are acceptable, for example, the device of the original LED lighting, the use of plastic and glass. Moreover, the facing of the concrete staircase with wood can be perfectly combined with any of the proposed options..

    Of course, the production of a monolithic concrete structure must be started, carefully prepared for work. For beginners in the field of construction, you first need to find out all the nuances of design and correctly calculate everything. After familiarizing yourself with the technological rules, pouring and finishing a staircase made of concrete will not be intimidating by excessive complexity, but it will require scrupulousness and accuracy. Performers who are not too confident in their abilities can be preliminarily trained on the device of the stairs on the site. Surely this valuable experience will help them in the future..
