Reinforced concrete slabs: technical characteristics

Reinforced concrete hollow-core slabs were probably seen by anyone who passed at least once past a city building site or entered a “bare” apartment. And even if you still did not see them, you probably walked on them, as this is the most common building material used in the construction of multi-storey buildings. About him and will be discussed in this article.

Description

Slabs of reinforced concrete coverings of floors and bottoms are monolithic reinforced rectangular structures with through circular holes, perfectly suitable for separating floors, creating their bases and roofs.

Virtues

• Affordable price. Acquisition and installation of finished slabs is much cheaper than suspended concreting or other ways of creating an intermediate surface between the floors of a residential or industrial building.
• High bearing capacity and strength. Only cutting reinforced concrete with diamond circles will be able to cause any damage. And the presence of a reinforced frame ensures resistance to pressure exerted from above.

• Convenient weight of reinforced concrete slab. Due to the presence of voids inside the product does not require additional strengthening of the foundation.

You should know: pipe through holes in addition to reducing the weight of concrete structures also serve to increase the resistance to deformation at fracture.

• Soundproofing. Allows you to isolate yourself from the noise of the lower and upper neighbors.
• Ease of installation work. Of course, you can't do it yourself with your own hands, you will need to use a special technique. But the process itself is more like picking up a designer than the usual construction work related to concreting or masonry.

• Water resistance. Perfectly withstand damp and even direct exposure to water.
• Long service life. Decades.
• Fire resistance. Fire safety in any room is of extreme importance, and reinforced concrete fully complies with its requirements.
• Seismic Resistance. Can withstand an earthquake of up to nine points without cracking.
• Resistance to various atmospheric conditions. Frost, heat, torrential rains and thick layers of snow will not be able to destroy the structure of the reinforced concrete section.
• Low thermal conductivity. The air accumulating in the internal voids is an excellent heat insulator. (See also the article Heater for concrete: features.)

Options

Plates of reinforced concrete coverings of floors and bottoms according to GOST have the following characteristics:

• The dimensions of reinforced concrete slabs in width can be 1 m, 1.2 m or 1.5 m. The length varies from 238 cm to 898 cm.
• The thickness of the reinforced concrete slab, regardless of the other linear parameters, is usually 22 cm.

• The load capacity is 800 kg per square meter.

Due to the accuracy and variety of sizes, it is easy to calculate the reinforced concrete slab specifically for your case.

Tip: if you have difficulty calculating the required amount of building materials, you can always use one of the many online calculators offered on the Internet. In this case, it will be enough for you to enter the parameters of your building, and the program will give you a detailed answer, which also contains the final cost of the reinforced concrete floor slabs.

Additional views

Reinforced concrete hollow core slabs can also have some other forms, which, although less often, are still used in construction:

• Ribbed. They have excellent resistance to mechanical stress, but because of the uneven surface they are not used for the construction of residential buildings, only for industrial ones.

• Full bodied. These products do not have internal voids and related advantages. But they have the highest concrete strength and are used in places of high load.

Spheres of application

The instruction assumes operation above the described products in the following areas:

• As a carrier base for buildings of various kinds: multi-storey buildings, private houses, premises of industrial and public importance.

• Creating a ceiling between the floors of a high-rise building. Almost all the high-rise buildings in which you have been are built according to this principle.

• Construction of tunnels and heating mains. Their strength properties allow them to easily keep the soil from shedding.

Conclusion

Few significant construction today can afford to do without the use of reinforced concrete floor slabs.

1. They make it possible to optimally solve many design problems efficiently and economically.
2. They have high strength, moisture resistance, fire resistance, thermal insulation, durability and simple operating instructions.
