Technical characteristics of prefabricated stairs

Prefabricated stairs are a comprehensive structural solution in vertical communication systems of buildings. They are manufactured from structural concrete of class C35/45 or C40/50, ensuring adequate load-bearing capacity and durability. In addition, each prefabricated staircase is protected against corrosion by using appropriate reinforcement lagging of at least 35 mm.

The production process takes place under controlled factory conditions, where precast concrete stairs are formed in precision steel molds. Then intensive compaction of the concrete mixture by vibration is applied. At the same time, the surface of the steps is profiled to provide anti-slip properties.

Prefabricated stairs – advantages of the solution

Ready-made concrete stairs are characterized by a much higher quality of workmanship than elements poured on site. Production in hall conditions allows to obtain the ideal geometry of each step. In addition, prefabricated st airs are subjected to quality control, which includes checking dimensions and strength parameters.

The prefabrication system makes it possible to manufacture stairs of any configuration – single-run, double-run or staircase procedure. Standard widths of gears are from 1.0 to 1.5 meters, adapted to functional requirements. But at the same time, the construction of prefabricated stairs provides full stability and rigidity without additional support.

The precast concrete staircase exhibits excellent fire resistance at REI120 to REI240. The massive structure also provides effective sound insulation between floors. As a result, prefabricated stairs meet the highest requirements of building and fire regulations.

Reinforcement is made of A-IIIN class steel (RB500W) in an arrangement adapted to the imposed loads. The number and arrangement of reinforcing bars in each prefabricated staircase is determined on the basis of static calculations. Then the finished concrete stairs receive technical documentation with load-bearing parameters.

Advantages of prefabricated stairs

Speed of installation of prefabricated stairs

Prefabricated stairs are delivered as complete pieces ready for immediate installation. Installing an entire flight of stairs using a crane takes a few hours instead of the weeks needed for traditional construction. In addition, the elimination of formwork and reinforcement at the construction site significantly reduces labor. As a result, the installation of prefabricated stairs reduces construction time by 80%.

Precision of dimensions

Production in steel molds ensures dimensional accuracy of each step with a tolerance of +/- 3 mm. Identical height and depth of all steps in the run guarantees comfort and safety of use. In addition, the smooth surface of prefabricated concrete stairs does not require additional leveling. As a result, prefabricated concrete stairs are immediately ready for finishing.

Strength and load-bearing capacity of prefabricated stairs

The use of C35/45 grade concrete in prefabricated stairs ensures a load carrying capacity of 5.0 kN/m². Appropriate reinforcement with RB500W steel guarantees the transfer of dynamic loads without scratching. In addition, monolithic construction eliminates vibration and creaking during use. As a result, prefabricated stairs maintain their parameters for decades of use.

Fire resistance of the structure

Precast concrete stairs have a fire resistance class of REI120 as standard. The solid concrete structure provides an effective barrier to the spread of fire. Subsequently, the absence of combustible structural elements increases the safety of evacuation. Such resistance makes precast stairs ideal for escape routes.

Possibility of finishing prefabricated stairs

The smooth surface of finished concrete stairs provides an excellent base for various finishing materials. It is possible to cover with ceramic tiles, natural stone or carpet. In addition, precast outdoor stairs can have a textured anti-slip surface. Such versatility allows it to fit into any architectural concept.

Cost-effectiveness of the solution

The use of prefabricated stairs generates savings in the cost of labor and auxiliary materials. Elimination of system formwork, reinforcement and ready-mixed concrete reduces expenditures by 40-50%. In addition, the shorter execution time translates into faster commissioning of the building. As a result, the total cost of stair construction can be 30% lower.

Service life of prefabricated stairs

Precast concrete stairs are designed for a minimum of 100 years of use. The use of concrete with frost resistance class F150 guarantees resistance to weather conditions. In addition, the appropriate reinforcement cover of 40 mm protects the steel from corrosion. Thanks to these parameters, prefabricated stairs retain their properties throughout the life of the building.

Variety of types and configurations

The prefabrication system makes it possible to make stairs with any geometric parameters. There are single-run, double-run, interval or spiral stairs. Then it is possible to make prefabricated slope stairs for off-road applications. Such flexibility allows optimal adaptation to any architectural design.

Application of prefabricated stairs

Prefabricated stairs are universally used in all types of construction as elements of vertical communication. The primary use is for staircases in multi-family residential buildings and office buildings. In addition, prefabricated concrete stairs are an optimal solution for public buildings requiring high durability.

In residential construction, prefabricated concrete stairs are used as main walkways. They are especially often used in apartment blocks and development estates. Then, in single-family houses, prefabricated stairs are installed as stairs to the basement or utility attic.

Prefabricated outdoor stairs are perfect for building entrances. They are used at schools, offices, hospitals and shopping centers. In addition, they are used as terrain stairs in parks, on slopes or amphitheaters. Thanks to their resistance to weather conditions, prefabricated stairs maintain their aesthetics for years.

Special use is found for prefabricated stairs in industrial and storage facilities. External escape stairs made as prefabricated products meet fire safety requirements. At the same time, technical stairs for handling equipment are characterized by high load-bearing capacity. As a result, prefabricated concrete stairs provide safe communication in production facilities.

Prefabricated slope stairs are increasingly used in infrastructure construction. They are used for underpasses, pedestrian bridges or railroad platforms. In addition, the installation of prefabricated stairs at sports venues enables the rapid construction of grandstands. Thanks to their modularity, prefabricated stairs create coherent communication systems.

Technical parameters of prefabricated stairs

Prefabricated st airs are manufactured in accordance with the PN-EN 14843 standard for prefabricated stair elements. The standard class of concrete is C35/45 with a characteristic strength of 45 MPa. In addition, each precast concrete staircase has a declaration of performance and CE marking.

The strength parameters of prefabricated stairs include a load capacity of 5.0 kN/m² for residential buildings. Fire resistance is determined at REI120 to REI240, depending on the thickness of the running board. Subsequently, the friction coefficient of the tread surface is a minimum of μ = 0.6. The sound insulation of precast concrete stairs is Rw = 55-60 dB.

The reinforcement of prefabricated stairs is made of A-IIIN class steel (RB500W) with diameters from 12 to 20 mm. The spacing of main bars is 100-150 mm, depending on the imposed loads. In addition, distribution bars fi 8-10 mm are used every 200-250 mm. The lagging of the reinforcement is a minimum of 35 mm from the bottom and 25 mm from the top.

The standard dimensions of prefabricated stairs are the width of the flight 1000-1500 mm, step height 150-175 mm. The depth of the step is 250-300 mm according to ergonomic requirements. However, the thickness of the running board is 120-180 mm, the resting board is 150-200 mm. The unit weight of finished concrete stairs is about 350-450 kg/m² of projection area.

Installation of prefabricated stairs

Preparation of the support structure for prefabricated stairs requires making support sockets in the walls or beams. First, the height ordinates of the supports are checked with a tolerance of +/- 10 mm. Then a layer of leveling mortar or elastomeric pads is laid in the sockets. In addition, the installation axes that determine the exact position of the precast concrete stairs are determined.

Transportation of prefabricated stairs to the construction site is carried out using low-loader sets. Unloading is carried out with a crane with the appropriate lifting capacity using belt slings or assembly frames. In addition, the elements are stored in the assembly position on stable supports. Before installation, each prefabricated staircase is checked for compliance with the project.

Embedding of finished concrete stairs begins with the lower rest or support beam. The element is lifted at the points indicated by the manufacturer, maintaining balance. At the same time, the stair treads are lowered slowly into the support sockets with a minimum support of 100-150 mm. Correct alignment is controlled with a spirit level and plumb line.

Stabilization of prefabricated stairs is realized by concreting the joints in the support sockets. The connecting reinforcement is anchored in the mounting holes filled with low-shrinkage mortar. Then the fusion with the building structure is performed by concreting the rims. The assembly of prefabricated stairs is completed by filling the joints with elastic sealing compound.

Quality control of the installation includes verification of the stability of each run and rest. The usable dimensions – the width and height of the steps and the inclination of the run – are verified. In addition, the continuity of handrails and balustrades mounted to prefabricated stairs is checked. As-built documentation should include acceptance protocols and certificates of the connecting materials used.
