Prefabricated monolithic overlap with your own hands

Any construction of the horizontal position must have overlapping. It is necessary to separate adjacent rooms and perform some protective functions. At present, prefabricated-monolithic overlap can be completely erected on its own, without resorting to the help of professionals. All you need is time and desire, as well as some theoretical knowledge that you will get from this article.

About features of precast-monolithic technology

This type of overlapping appeared relatively recently. It is for this reason that not all of them are still using them, nevertheless, the future is behind them. Let's take a short look at what this technology represents.

Today you can buy blocks of 6, 4 and 3 meters long, of course, that they have different weights. In addition, there are two types of monolithic girders per bearing structure: 900 and 1300 kg / m ² . If you are going to do this kind of overlap, then the concrete is compacted by bayonet, which is necessary to ensure adhesion. In addition, manufacturers have achieved good structural characteristics through the use of porous concrete. If the prefabricated-monolithic overlap is made of polystyrene, then the structure has a relatively small weight with good load-bearing capacity. At the same time, the load on the walls of the building is also reduced, which, without a doubt, is a significant plus.

Prefabricated-monolithic ceilings with own hands

When performing the work, it is necessary to follow the technology and consistency. In addition, it is important to do everything slowly and qualitatively, only in this way you can get a really reliable design.

At the first stage, stacking beams are laid. The surface of the wall should already be cleaned and laid with a layer of concrete 1-1.5 cm. At the same time, the depth of support should not be less than 12 cm, and the deadbolt - 9 cm. Beams for the time of work should have an inventory support, remember this. It is desirable that the supports were every 1.5 meters. Transverse blocks are stacked in series, transverse rows. This is necessary in order to exclude the loading of runs. Pay attention to ensure that the gap between the blocks was as small as possible.

The reinforcing mesh lies on top of the structure , preferably overlapping, after which the surface is cleaned before concreting. In principle, to build prefabricated-monolithic ceilings with their own hands on this almost ends, there is only concreting.

A little about the advantages of systems

Of course, no one wants to buy what, in his opinion, is not good enough or effective. But in this case you can be sure of excellent performance. For example, prefabricated-monolithic overlap will cost much less than slabs or monolithic systems. With all this prefabricated structures are not inferior to them in strength, but on the contrary - they win. Of course, we can not say about the price of installation, which is much lower. This is due to the fact that there is less need for raw materials for the installation, so labor intensity is significantly reduced. All these advantages allow using prefabricated-monolithic overlapping not only in private construction, but also in the industrial sector. Such overlappings are capable of withstanding loads of up to 1.3 tons and are mounted even where seismicity reaches 7-8 points.

What will be interesting to everyone

We figured out the advantages of these overlaps, and now I would like to say about what else they will be useful for you. First, the need for a removable expensive formwork will disappear, and the amount of mounting equipment will be significantly reduced. You will have enough support for the longitudinal beams. There is no need to use such heavy equipment as cranes, and this is a significant saving. In addition, you do not need high qualification, and the speed of the work will be slightly higher.

For example, a team of 3 people and three working days will be required for 100 square meters. Of course, it makes sense to say that significant savings are achieved through the work itself. If the prefabricated reinforced concrete blocks (monolithic) are assembled by specialists, then it is not worth much hope for. But that is not all.

A few words about shortcomings

As practice shows, such designs have only one significant drawback - the need to mount the formwork throughout the area where construction work is being performed. Nevertheless, you can go an alternative way and find a way out of this situation. For example, the installation of separate, rather than integral formwork, will significantly reduce the complexity of the process. It can be collected in the course of the work, which is more convenient. In addition, prefabricated-monolithic slabs require a reinforcing cage with a cross-section of at least 8 mm. This requirement must be fulfilled to obtain a high-quality and, most importantly, strong and reliable design. In principle, there are no other drawbacks to this solution, so it is so popular and in demand. In the coming years, prefabricated structures will only become more popular.

Prefabricated-monolithic interfloor overlapping

Ordinary interfloor monolithic overlap is much more difficult to establish, which is due to their high mass. Today, such structures in multi-storey buildings are not used too often. Sometimes this is associated with a heavy load. However, they are installed as an overlap between the last floor and the roof. But often the installation is carried out between the first and second floors. The fact is that this design allows you to transfer the weight of the structure and furniture indoors to the bearing walls, which is very convenient and profitable. But you always need to have a project with you: if there is not one, then work should be left to professionals. Although in your house you are free to do anything, but remember the risk. If you know a little about this topic, it will not be a problem for you, especially if you use blocks of small length, since their mass is much smaller than long overlaps.

Finally

Today, a huge number of manufacturers are represented on the market. Which of them will you choose, your case. Domestic products are very popular prefabricated-monolithic floors "Marco". Consumers say not only about the affordable cost of products, but also about the quality, as well as the high strength of structures. In addition, if there is a desire, you can hire specialists who will do everything for you. In any case, prefabricated systems look profitable against the background of conventional monolithic ceilings, which have a significant weight and are installed by large forces and equipment. However, do not expect that all new buildings will be made of prefabricated structures, since a large stock of plates must be left somewhere. In principle, that's all.
