Construction of houses from a gas-block by own hands: features, calculation and recommendations

Modern technologies are aimed at making building materials sufficiently firm and durable, durable and waterproof. In addition, they must have ideal indicators of thermal conductivity. With a decrease in the specific weight of the product, manufacturers are increasing their sizes, which contributes to a reduction in the time for building construction.

Which material to choose

As for aerated concrete, it has all of the above characteristics and has a perfectly flat surface from the outside. This indicates that it is very convenient to decorate the walls from the gas block, the work will be able to be carried out fairly simple and in a short time. If you are also interested in building houses from a gas block, then it's worth getting acquainted with technology, about which we will talk later.

Preparing the foundation

In order to choose the foundation for a gas-aerated building, several aspects need to be taken into account, the soil characteristics should be included here. From the constructive mass of the house will depend on the type of foundation. Aerated concrete - this is a fairly light material, so you can save on the device foundation, without worsening its load-bearing capacity. To do this, the type of foundation varies, and it is possible to use its plate variety, having abandoned a heavy tape or pile foundation.

Construction of houses from a gas block is most often carried out on a load-bearing plate, which has a high support area and is capable of undergoing structural loads. Deepen such a foundation too much will not have to. The amount of excavation and labor will be reduced, as will the total cost of construction. Begin work is necessary with excavation and site marking.

The process is not laborious. To do this, prepare a 30-cm trench, at the bottom of which is laid a pillow of sand. It should be well tampered with, the more qualitatively it can be carried out, the more ideal the masonry will be. It is better to use a vibrating plate, which can be rented.

At the next stage, the installation of communications is carried out, where the sewage system and the water supply system should be included. Then you can proceed to the formation of a strong and perfectly flat screed made of concrete, which will protect the pillow from damage. Construction of houses from the gas block at the next stage provides for the construction of the formwork. Side seams must be laid with polystyrene foam, which will ensure high-quality thermal insulation.

Once the cementitious screed has hardened, it can be covered with a waterproofing layer, paying particular attention to the seams between the insulating material. The top layer can be formed from dense polyethylene. Next, a framework of reinforcement is installed. The distance between the elements can be 40 cm. Now you can start pouring concrete, to withstand it until it is completely congealed and set strength. This will take about 2 weeks.

The construction of houses from the gas block provides for compliance with certain rules. They say that the moisture from the foundation should evaporate gradually. To do this, the plate is covered with a cloth, and the surface of the structure is moistened periodically. It is important to remember that aerated concrete requires waterproofing. Between the foundation and the main wall, it is necessary to lay a layer of the corresponding material.

Mounting blocks

Aerated concrete products must be laid in a row, fixing them among themselves not with cement mortar, but with special glue. The thickness of the joint should not be 2 cm, but 5 mm. The glue is applied by a notched trowel, however, professionals can use another tool.

Aerated concrete can also be laid on a cement-sand mortar, but it will be difficult to fit the products, providing even walls. Saw aerated concrete blocks in size can be using a grinder with a disc on a stone or an ordinary saw. In the room to work with an angle grinder is not recommended, because a large amount of dust will form. That's why the master should use a respirator.

Armo Pole Stacking

The construction of a house from a gas-block with its own hands provides for the formation of an armo-pile, since the material described does not have a sufficient level of rigidity and strength. Reinforcement can be done with brickwork on top of the block, which is true for small houses.

If we are talking about a spacious cottage, then armopoyas should contain reinforcing bars. The two-story building requires the construction of armopoyas before the second floor, this structure will rely on the slab or lag.

Formation of partitions and walls

Choosing the best gas block for building a house, you should pay attention to the one that has a thickness equal to 380 mm. It is such parameters that a bearing wall can possess. However, this does not indicate that all internal partitions should be built of the same aerated concrete blocks.

On sale, you can find 10-cm blocks, which are under great load. To reduce the cost of construction, it is not necessary to choose the density of D500. With a decrease in the block density, the heat insulating qualities increase. This is due to the size of the cells.

For the construction of walls, blocks with tongue and groove should be used. It is more convenient to carry them by hand. The dried foundation must be cleaned of dust and dirt, only after that it is possible to start laying the roofing material and forming the first row. To do this, you can use a conventional cement-sand mortar, which will dry somewhat longer than a special glue. This will allow you to adjust the masonry.

After you can find the highest angle, you should start building. With the help of the line, the upper edge of the blocks should be marked. The smoothness of the laying of each block should be checked with the help of a building level. Before you begin laying the second row, you need to grind the surface of the previous one. This treatment will ensure the highest possible level of applied adhesive. It is necessary to start from corners in this case. Types of each other are bandaged by the method of shifting the products by half. The minimum allowable shear value is 80 mm.

Window arrangement

If the sill is to have a height equal to four rows, then the openings should be formed after laying the third row. To do this, you need to use a shtoborez. In the place where the window opening is supposed to be located, two parallel lines must be cut. In length, they should extend 300 mm beyond the boundaries of the window. Strokes should be laid with rods and fixed with mortar. At this stage, we can assume that the wall for installing the window is strengthened.

Which aerated concrete block to choose

Quite often, consumers are wondering which gas block is best for building a house. First of all, it is important to pay attention to the thermal conductivity. The lower it is, the higher will be the thermal insulation characteristics. For example, if you have a D350 block in front of you, its thermal conductivity will be 0,075 W / (m · K), as for D700 blocks, they have a thermal conductivity of 0.25 W / (m · K).

In order to achieve the desired thermal insulation with the brand of the gas block within the D400-D500, it is necessary to form walls with a thickness of 35 to 45 cm. If you are faced with the question of what are the best parameters of the gas unit for building a house, it is important to pay attention also to the strength, As well as density. The lowest density of products in the D300. The higher the value, the more dense the block is in front of you.

Choosing products with low density, you acquire blocks that are subject to mechanical damage. They will easily be amenable to processing, which speeds up and facilitates clutching. One of the important parameters is the size. The optimum parameter for the bearing walls is 60 x 30 x 20 cm. The partition can have the same dimensions, but it will differ in thickness, this parameter will be 10 cm.

Price of houses

The construction of a house from a gas block, the price of which will be equal to 2,500,000 rubles, may suggest the creation of buildings of different sizes. In this case we are talking about 142 m ² , while the size of the base is 13 x 9 cm. The price is reduced to 1,070,000 rubles, if it is a house with an area of 70 m ² . The size of the base will be 7 x 6 m.

The construction of houses from gas blocks, projects whose prices are mentioned in the article, can be carried out by yourself. For example, a house in 155 m ² with a base size of 15 x 11 m will cost 2 000 000 rubles.

Self-calculation of material

Calculation of gas units for the construction of a house involves the use of the following formula: (L x H - S pr) x 1.05 x V = V. In it, L is the total length of the walls in meters. Under the letter H is understood the height of aerated concrete walls in meters. The total area of doorways and window openings in square meters is denoted by S pr. The coefficient that should be taken into account as a reserve for pruning is 1.05. The thickness of blocks in meters is denoted by the letter B, as for the calculated volume of aerated concrete in cubic meters, it is denoted by the letter V.

Conclusion

Aerated concrete house involves fixing the waterproofing on top of the rafters. This should be done with wooden rails. They will play the role of a rebound, to which the roofing material will be fixed at the next stage. Under the waterproofing between the slats should be laid insulation. For this, mineral wool is usually used. As an alternative solution, polystyrene foam or expanded polystyrene foam may be used.

Thermal insulation must be protected by a vapor barrier, which is fixed to the rafters with wooden slats. At the final stage, you can start laying the finish coat. In this case, you need to focus on the budget and personal preferences, and you can use slate, corrugated board or ceramic tiles.
