Reinforced concrete stairs: design features

Building

Ladders from concrete with the basis from metal fittings are very popular in modern construction. They are practical, have a long service life and, with proper maintenance, require almost no maintenance. At the same time there is a special GOST for reinforced concrete stairs, which allows you to create products of a certain quality and size.

Types of designs

Для начала стоит упомянуть о том, что подобные системы имеют очень много разновидностей и конфигураций. Они используются как в многоэтажных домах, так и в строениях с двумя ярусами. При этом железобетонные монолитные лестницы могут не только иметь различную форму, но даже отличаться по ширине и высоте ступеней (читайте также статью «Железобетонные шпалы: основные разновидности, характеристики и особенности применения»).

Factory products

These types of similar structures are created at special enterprises and have strictly defined parameters.

Therefore, when designing a building, it is very important to know the GOST for reinforced concrete staircases that are planned to be used in order to make their dimensions in advance.

A factory span made of reinforced concrete is only part of a flight of stairs and needs additional elements.

It should be noted that there are several specific types of such structures that are in great demand. However, if necessary, the manufacturer can always create other types of products, but only according to previously developed standards or in accordance with the individual project of the customer, who will be responsible for the operation of these systems.
Usually factory products resemble prefabricated sections. They are delivered at the facility and there, using welding and special fasteners, they are mounted into place.

Composite designs require the use of parts of only a specific marking and preferably from a single manufacturer.

It must be remembered that when installing such structures, diamond drilling of holes in concrete may be required in order to be fixed to the wall or floor. Seats for mounting the railing are usually done at the filling stage to simplify the work.
Special attention should be paid to the fact that for each specific product the manufacturer must issue the appropriate documentation that would confirm the proper quality. This is due to the fact that the stairs of monolithic reinforced concrete, even from one party can be very different from each other.

Tip! It is necessary to use such structures strictly according to the rules of their operation, following all the recommendations of installation. Otherwise, even the most reliable and proven product can create a defect in the entire system or collapse from the inside.

Self-made designs can have the most unusual shape and configuration that the customer wants to see.

Homemade systems

Quite often, staircases and reinforced concrete staircases are made directly on the object or in the building structure.

At the same time, this method allows you to make the whole system monolithic with floor slabs and other parts of the structure.

Independent production of a staircase requires the prior creation of formwork and the work of a bundle with the bearing elements of the building.

It should be noted that the independent production of reinforced concrete stairs makes it possible to make any changes and additions to the design. However, it is worth remembering that all of them should not reduce the strength of the final product and reduce its functionality.
Most professional craftsmen to create a solid and at the same time individual design first prefer to make a strong metal frame or put a metal corner or an I-beam as a guide for the stairs.. In this case, it may be necessary to cut the reinforced concrete with diamond circles in order to create seats in the floor slab.

Creating projects of flight of stairs, you should be guided by the existing GOST, since they take into account all the elements of safety and convenience, which at the same time will greatly facilitate the process of making calculations

The height and width of reinforced concrete steps of own production can be made by anyone, but the main thing is that all tenants, especially children and pensioners, can use the finished structure. Therefore, the masters try to adhere to generally accepted standards, since they were designed to meet all the needs, including fire safety.
It should be said that the price of such a construction with its installation will be significantly lower than the cost of the factory product, its delivery to the object and subsequent installation.

Tip! When creating such structures, professional craftsmen recommend tying them to walls and floor slabs at the reinforcement stage prior to casting. At the same time it is not bad to create a kind of lock using the casting form

If you create this item yourself, you can equip it with any necessary devices or additions that will have a functional or aesthetic component.

Recommendations

If the work is done by hand, then at first it is worthwhile to create a project not only for the entire building, but also the flight of stairs that is planned to be created.

It should be shown to a specialist to make his own amendments or additions.

Some of these products are based on a durable metal frame, which itself is actually a ladder, and only steps and decorative elements are poured from concrete

First of all, this design requires reliability and safety, and only then convenience and beauty. Otherwise, the use of the final product is not recommended.
It is worth noting that the installation instructions necessarily imply the presence of a railing, not only for the convenience of lifting or descending, but also for fencing the danger zone, preventing the fall.

Composite spiral staircases are also made of reinforced concrete by some enterprises, but they are supplied immediately as a result of the complexity of the structure.

Conclusion

Ознакомившись с видео в этой статье можно детально изучить подобного рода изделия и способы их изготовления. При этом на основе статьи, которая переведена выше, следует сделать вывод о том, что лестница является очень важным и ответственным элементом здания, которое требует повышенного внимания не только при создании, но и на стадии проектирования (см.также статью «Железобетонные сваи: разновидности и назначение»).
