Types Of Reinforced Concrete Molds Structures

Without them, it is impossible to build offices, high-rise buildings and industrial buildings. Reinforced concrete molds structures allow you to quickly. And with minimal financial costs to build houses of degrees of complexity.

REINFORCED CONCRETE

Concrete has great strength. This allows you to build buildings with a long service life. In addition, it can withstand temperature changes well. Other useful parametrs of this material include: frost resistance, high density, water resistance, fire resistance. The compressive strength of concrete is 10-20 times greater than the tensile strength. This parameter largely depends on the sand and gravel used. It is the cement that how strong the composition will be. Filling with concrete allows you to protect the corrosion.

Porosity, namely the ratio of pores to the total volume, greatly affects the quality of the material.

Density is the ratio of the mass of concrete to its volume. The higher this characteristic, the stronger the reinforced concrete structure will be. Due to its high density, concrete resists compression well. Regardless of the reinforced concrete structure. It can effectively transfer heat flow. The thermal conductivity of concrete is 50 times less than that of steel, but much higher than that of brick. The result of low thermal conductivity of reinforced concrete structures is their fire resistance. Due to this, this material is also used in the arrangement of industrial workshops, where it is necessary to work with high temperatures.

Important! There are pores in any design. They appear as a result of evaporation of water that has not reacted with cement. Very often, a large porosity is evidence of the use of an insufficient amount of cement in the mixture.

An important characteristic of concrete is its frost resistance. This material, when saturated with water, can withstand multiple temperature changes without any consequences. The percentage of strength reduction is minimal. Nevertheless, concrete has one significant drawback. Its tensile strength is extremely low. Therefore, reinforced elements are added to the structure. For example, steel wire or rods. The single reinforced concrete structure has high strength and good tensile strength. In addition, the technology of creating these products has changed a lot over the past 150 years and continues to improve every day.

WHAT IS REINFORCEMENT

Reinforcement allows you to create reinforced concrete structures for the ages. The best example in this context is the construction of a strong and durable floor. In the process of work, a screed on a metal base is carried out.

Concrete floor can be of the following types:

  • self-leveling;
  • based on the ground or slabs;
  • screed with a layer of thermal insulation;
  • screed based on floor slabs.

In addition to increasing the strength of the reinforced concrete structure. And reinforcement reduces the cost of concrete. In the process of work, materials such as: reinforcement frame, fiberglass mesh, wire rod mesh, welded mesh with cells, polymer mesh, fiber fiber can be used. A wide selection makes it possible to choose the best option for creating a high-quality and durable reinforced concrete structure.

MONOLITHIC REINFORCED CONCRETE STRUCTURES

The developer himself determines the validity of the use of a certain amount of materials, depending on the degree of complexity of the object and its purpose. This allows you to create a more flexible estimate, really assessing the needs of production. The main advantage of monolithic reinforced concrete structures is their spatial integrity. If we take professional terminology, then this is a high static uncertainty.

Due to this, monolithic structures have a low material consumption. These products allow you to build objects using different types of formwork, including: fixed, mobile, panel, block.

Also, this technology allows you to establish a mechanized supply and laying of concrete. There are a number of structures that are created only with the help of MZHK, they include: swimming pools, foundations, structures with powerful dynamic loads. In each of the above options, the use of monolithic reinforced concrete structures is economically advantageous.

Despite the serious advantages, this technology has its drawbacks, including:

  • seasonality of work;
  • construction time largely depends on the rate of the mixture.

Work with concrete structures is carried out only in the warm season. To speed up the process, special grades of cement are used, which harden extremely quickly.

PRECAST-MONOLITHIC REINFORCED CONCRETE STRUCTURES

Are a whole complex of elements. To achieve the desired result, prefabricated structures can have different shapes and sizes. In complexes of this kind, tensioned and non-tensioned fittings can be used. It all depends on the specific situation and the purpose of the object.

If the surface of precast-monolithic reinforced concrete structures has a high level of roughness, then you can do without dowels. In places where the prefabricated elements come into contact with the concrete. The release of transverse reinforcement is provided. The anchorage is laid in monolithic concrete additionally. Important! Precast concrete in these structures is the formwork for the monolithic component. Precast-monolithic reinforced concrete structures combine the advantages of both previous types. They are very economical and allow you to build buildings using modern methods quickly and efficiently.

Important! Monolithic reinforced concrete guarantees high spatial rigidity. This reduces the material consumption. Lightweight and cellular concretes are widely used in monolithic elements. The use of artificial porous aggregates is allowed. Because of this, the specific weight of the structure is significantly reduced.

 

RULES FOR CREATING RELIABLE REINFORCED CONCRETE STRUCTURES

In the process of work and construction standards must be observed. Some organizations additionally rely on international standards to gain an important competitive advantage.

It is necessary to avoid getting into the reinforced concrete structure of oil substances. They prevent the formation of a strong bond between the concrete and the frame. To protect the reinforced concrete from corrosion, the concrete must completely hide the reinforcement elements.

Concrete fence posts

One of the options for installing fences are concrete pillars – monolithic supports of various configurations and cross-sections, reinforced with a reinforced frame. Such products have both their advantages and some minor disadvantages. For the arrangement of light fences (profiled flooring, picket fence, euro-picket fence, polycarbonate). Their use is also quite justified precisely due to their positive properties.

Varieties and advantages of concrete pillars

The main criterion by which concrete fence posts differ is their cross-section, that is, the shape of the contour in the section.

There are several of them, but the following are particularly popular:

  • square ones;
  • rectangular;
  • trapezoidal;
  • round;
  • semicircular.

Lovers of originality and prestige often prefer combined concrete pillars. An example is the option when casting supports using formwork with a complex. But symmetrical configuration-combined and round areas, and square, and others.

In addition to the shape of the fence posts differ in the way they are attached to the fence sections. There are options with longitudinal landing slots. With embedded wooden bars or metal hinges. Which of the options to use depends mainly on what type of fence is planned to be installed.

For example, the configuration of concrete monolithic posts with longitudinal grooves is most often used for the installation of cast fences. If the sections for the spans are wooden, then the best option will be embedded bars made of the same material.

Another criterion by which monolithic fence posts differ is the method of their installation.

Of the advantages of concrete fence posts, the following advantages deserve attention:

  • firstly endurance;
  • secondly solid appearance;
  • durability;
  • compatibility with many types of fencing.

If you compare them with metal supports, the price tag can be significantly higher. But if you take into account the brick, concrete will be much more attractive on a budget.

The second significant, in the direct sense of the word, is a lot of weight. What to make concrete pillars, what to install ready – made-it is quite difficult, and it is not always possible to do it yourself.
