Concrete frame in low-rise construction - the main

In this article we will talk about what constitutes the concrete frame of the house, what are its operational and technical characteristics. In addition, we will try to find out whether it is possible to use monolithic structures in the construction of low-rise individual housing facilities.

We use effective methods in the construction of low-rise construction object

According to long-term statistics, monolithic construction is the most efficient and at the same time economical way of erecting multi-storey buildings.

The advantage of the method is the presence of reinforced concrete supporting columns and floors, which accept and evenly distribute the mechanical load, which favorably affects the durability of the building as a whole.

At the same time, the external walls made of thermosaving materials, laid between the columns, do not take any load on themselves. A typical example is the combination of building materials such as aerated concrete and a framework of reinforced concrete.

So, the advantages of monolithic construction are obvious and the question arises whether these properties can be applied when building a low-rise private house? It turns out that nothing is impossible, and concrete frames in individual construction are becoming widespread.

Main characteristics

There are many reasons that explain the permanently growing popularity of monolithic construction. But the main advantages of the technology are versatility, affordable price and short construction time. Speaking of universality, it should be noted that the combination of a concrete frame and aerated concrete blocks allows you to design and build buildings of any sizes and any architectural forms.

In addition, in such houses, you can use the free layout of the premises and, if necessary, change the configuration of the living space using diamond drilling holes in concrete without reconstructing the entire building.

Important: Buildings that are based on a monolithic reinforcing structure are distinguished by walls without through joints. As a result, the degree of thermal conductivity of a building significantly decreases and, as a result, its energy efficiency increases.

Monolithic technology, tested in the construction of high-rise apartment buildings, is gradually being introduced into the sphere of low-rise construction. And this is not surprising, since thanks to this technology it is possible to construct construction sites on virtually any soil and in adverse seismic conditions.

Consider the features of the construction of the frame with your own hands.

The technology of construction of monolithic concrete structures

If the question is, what to choose aerated concrete or frame, choose a monolithic frame, inside which we will lay aerated concrete blocks.

Important: The construction of a monolithic structure can be entrusted to specialists from specialized organizations. But the price of such a proposal is likely to be high, and therefore we will consider the main stages of the independent construction of the frame using available building materials.

Instructions for the construction of structures of monolithic concrete is as follows:

• Directly on the construction site is going to a special form - formwork. Formwork is a design that follows the contours of future structural elements (load-bearing walls, columns, etc.).
• Next in the formwork is set the frame of metal reinforcement.
• Then concrete is prepared and poured directly into the formwork.
• As the mixture dries, the formwork gets loose and you can proceed to the subsequent construction work.

So, we have listed the main stages of building a monolithic frame, now we will tell about them in more detail.

Features formwork manufacturing

Two things depend on how well the formwork is made:

• First, it determines how stable the structure will be to hold the slurry..
• Secondly, how exactly the formwork is knocked down depends on how the finished concrete structure will look and whether it will be necessary to spend time and effort on its subsequent refinement..

There is a perception that for the construction of formwork can apply the variegated croaker, because one way or another the material will be spoiled. In fact, this is the wrong decision, as loose joints between uneven boards guarantee the presence of gaps. In the end, after the formwork is broken, you will have to align the frame knocking multiple flows.

As an optimal solution for the construction of formwork, you can use inexpensive laminated plywood or waste one-dimensional lumber. Despite the fact that the price of such a solution will be higher than the cost of the construction of slab, after the concrete dries, the framework will immediately be suitable for subsequent construction.

In the manufacture of reinforcing cage, it is allowed to use a cold-deformed rebar with a diameter of 3-12 mm. You can familiarize yourself with the mating features of the frame in the corresponding articles presented on our portal.

Preparation and pouring of concrete

For the preparation of high-grade concrete with their own hands can not do without a concrete mixer.

From the materials required:

• cement brand M400 or M500;
• river seeded sand;
• filler.

The proportions for self-mixing are as follows: 2 parts of cement, 4 parts of sand and 3-4 parts of filler. As a filler, it is advisable to use medium-sized crushed stone for concrete, which is well mixed and allows you to achieve the optimum consistency of the solution.

After the concrete is ready, we pour it into the formwork. In order for the result to be of the highest quality, a special vibrator should be used which will compact the concrete mix. The formwork can be shot down not earlier than in 3-4 days.

Conclusion

So, now we know that the construction of a monolithic frame requires a special approach, since as a result of non-observance of technological prescriptions, it may be necessary to cut reinforced concrete with diamond circles in order to eliminate defects.

In addition, now you know how to cope with the construction of a concrete frame yourself. If you have any questions, watch the video in this article.
