Concrete stairs with his hands
Stairs - a complex architectural structure, inthe list of requirements which include reliability, safety, aesthetics and comfort. The owners of the houses we would like to serve it as long as possible and did not require the endless repairs. Because, among other materials used in the manufacture of staircases, the most commonly used artificial stone - concrete. According to the parameters of strength, according to artistic expression, in operational longevity it is no rivals, and just a concrete staircase is being built with their own hands without any problems.

Why stairs of concrete better?
Used in the manufacture of the material excellently transfers all rigors of intensive use, the concrete stairs in private homes arrange outdoor and indoor.
They are considered the best option for the construction of the central entrance group and to provide movement to the basement or attic, used in landscape design. Besides:
- monolithic construction has not become loose from the dynamic load elements;
- users will not get any negative creaking sounds, even if the finishing was made of concrete stairs tree;
- possible embodiment of any ideas of architects from elementary propulsion, more complex designs to screw hard-component configurations;
- minimal risk of fires;
- weight cladding options, compatibility and compatibility with any finishing and building materials.
Construction can be entirely monolithic orOnly one piece can be stringers, which are put up after setting the data frame elements concrete stair treads with no risers. In the latter case the lighter construction is obtained, both technically and in terms of ornamental, but installing it over the seating area is not desirable because of the gaps.
There is also a technical detail: Concrete stairs to the second floorIn the basement, the attic, on the porch can beproduced only at the object. Work carried out during the construction process and, unlike wooden counterparts can not be set after the completion of the interior design.
Choosing the optimal design
The entire process of concrete stairs construction is divided into three phases, are:
- assembling formwork - standard for creating any concrete and w / b construction work;
- assembly and mating fitting;
- directly to pouring the concrete stairs.
The most difficult and time-consuming step recognize assemblyformwork. If you intend to build a florid configuration, without the slightest doubt, it will need to instruct professionals. Formwork for staircases custom geometry without significant experience in this business can not be done.
The easiest way to fill odnomarshevuyu ladderplacing it between two walls. Then do not need the side formwork elements, it is sufficient to draw on the walls of the circuit. The design of the unit odnomarshevoy stairs can be a variety of interesting rounded shape of the bottom step.
More difficult will be performed odnomarshevyvariant adjacent the one side wall only, as it will be necessary to make an end shuttering element and set to support it supports. Much more difficult to fill in the design with two non-contiguous to the walls of the parties, to build a half-pace option zabezhnymi steps or landing. However, in general, with a simple geometry, if desired, it is possible to handle and original finish concrete staircase ceramics, wood, nickel-plated, wrought-iron details will make it unique.
Make a plan for future work
As with any architectural and functional structure staircase requires a preliminary design and analysis. A simple project to do at least a sketch format, the drawn by hand.
Those wishing to find out how to make a concrete staircase, you should know that:
- width dictated by DIN 18065 and domestic SNIP, shall be 0.8-0.9 m;
- standard step height of 17 cm;
- construction height must take into account the thickness of the upper floors, including the height of the floor pan with cover;
- the width of the stage, providing a comfortable pace, 29-30 cm;
- convenient to move the angle of 30 ?, but consider, if necessary, to reduce the area of the construction angle may reach 45 ?.
Too steep stairs will increase the likelihoodinjury. Technological limit of 45? also undesirable due to migration inconvenience. If desired, reduce the area in terms of better production of concrete stairs prefer to span two or more set or screw structure.
Important. The project should take into account the presence of fences, installation of embedded parts for it shall be provided for in the design.
The basis for design
Depending on the complexity and size of the widthflight of stairs the weight of the concrete will be from 1.5 to 2.5 tons. Because you need to consider prior to the erection of the base unit issues, the most common form of which is w / w beams and foundations. If the base will serve as the screed on the ground, the ground underneath must be sealed and calculate the weight of the monolithic structures are not put pressure on her with a force greater than 1 kg / cm ?. It should be remembered that the finishing stages of the concrete stairs, for example, natural stone will significantly increase its weight. If the load exceeds the allowable value, it is better to sheathe timber.
Important. Precast concrete stairs concrete is not recommended to rely on screed made with foam insulation. Planning ladder will have to disassemble, then pour a special foundation.
Phased construction of concrete stairs
At the initial stage the formwork assembly is used:
- waterproof plywood (18-20 mm in the slice) and / or edging board (3 cm);
- lumber with a cross section up to 10 to 10 cm for the struts or supports?;
- to form curved surfaces of plywood 9 mm or narrow edging board.
The formwork should be no cracks or gaps. Connections are made using phosphated screws can be installed at the ends of the steel corners. After pour concrete all formwork elements are removed without problems.
In the finished formwork stacked along the marchsteel rods and valves are connected reinforcing cross-linked. Then establish wooden stoppers for the installation of a planned fence inserts. Then concrete is poured, which stamp must not be lower in strength than the B-15. Pour need entirely march, starting from the lowest level.
How can decorate the concrete stairs?
In order to reduce the burden on base oftenpreferred lining of concrete stairs with wood. Because wood can be carried out stage, balustrades and handrails. Appropriate nickel details fences, wrought iron grilles, the specific decoration on the supporting pillars.
Concrete wonderfully blends with any material, because in the aspect of finishing almost no restrictions.
All elements can be completely covered with wood or tiled with risers or partially cover only the upper part.
Valid range of special effects, for example,original LED lighting device, the use of plastic and glass. Moreover, concrete staircase lined tree can be combined perfectly with any of the options.
Of course, for the construction of monolithic concretedesigns need to proceed carefully prepare for work. For beginners in the field of construction, you must first figure out all the nuances of designing and correctly calculate all. After getting acquainted with the technological rules of filling and finishing of concrete stairs will not scare too much difficulty, but requires thoroughness and accuracy. Not too confident in their abilities performers can be pre-trained on the device stairs to the station. Surely this valuable experience will help them in the future.
