Modern technologies are aimed at making materials as strong as possible and meeting all requirements for thermal conductivity, hardness, durability and moisture resistance. By reducing the specific weight of products, manufacturers increase the size of the block, which helps to reduce the time for building a house.
In this case, we are talking about aerated concrete, which has all of the above characteristics, as well as a perfectly flat surface on all sides. Finishing walls from this material is quite simple, even a novice master can cope with the work in the shortest possible time.
If you decide to build a private house, then the density of aerated concrete should be D 500, the wall thickness should be equivalent to 380 millimeters (if you do not intend to make insulation). However, it is necessary to carry out external finishing work.
Foundation construction
Before you begin to build a residential building, you should definitely consider the projects of houses made of aerated concrete. In them everything will be painted to the smallest detail, including a variety of foundations. The type of foundation to be selected depending on many factors and aspects, among them, soil can be distinguished.
Aerated concrete is a fairly lightweight material, so you can save on the construction of a heavy foundation. You can abandon the heavy buried strip foundation or pile foundation by applying a slab foundation, since the carrier plate has a huge bearing area and will be able to undergo structural loads. It will not have to be deepened, which will reduce the complexity and volume of earthwork.
Foundation technology
You can create projects of houses made of aerated concrete yourself, however, most often modern developers trust this business to professionals. In order to build a foundation, you need to dig a 30-centimeter trench, laying a pillow of sand at the bottom. The main condition is tamper preparation.
Ideally, it is worth using a vibrating plate, and at the next stage you can lay all the communications according to the type of water supply and sewage systems. After carrying out these manipulations, you can make a solid screed of concrete, which will protect the structure from damage. Next, formwork is built - the side seams must be protected with foam sheets for thermal insulation. After the cement screed hardens, it is covered with a waterproofing layer. It is important to strengthen the future foundation by laying the frame of the reinforcement. The distance between the elements of this system should not seem more than 40 centimeters. Only after this can you start pouring concrete.
Laying aerated concrete blocks
Projects of houses made of aerated concrete are presented in the article. You can borrow one of them for your own construction. After the foundation is ready, you can start laying walls using cement mortar. Seams should be formed so that their thickness is equal to the limit of 3 to 5 millimeters. The composition is applied with a notched trowel. For the reason that the blocks are perfectly even, fitting them will be quite simple. If you need to cut the product, you need to use a grinder or an ordinary saw. Aerated concrete is quite easy to process, it can not only be cut, but also cut and planed.
Armopoyas
Projects of houses made of aerated concrete quite often provide for a second floor. In this case, 2 armored belts need to be equipped, the last of which will be supported by floor slabs or logs. The formation of the first floor should be carried out with brickwork, as for not too heavy and small houses. If we are talking about a spacious cottage, then the armo-belt is laid out with reinforcing bars. It will be enough only two bricks in height.
The formation of partitions and walls
If you are not confident in your abilities, then you can order turnkey aerated concrete houses; projects will be prepared by specialists. With independent construction, the thickness of the bearing walls is best limited by an indicator that is equal to 380 millimeters. Internal partitions do not have to be made of aerated concrete blocks. On sale you can find special products whose thickness is 10 centimeters. It is important to remember that with a decrease in the density of the product, its heat-insulating qualities are higher.
The construction of the attic
Before starting the construction, you should definitely consider the projects, and the construction of houses from aerated concrete in this case guarantees to be successful. After completion of the formation of the walls, you can proceed with the construction of the rafter frame. Initially, you need to lay and fix the Mauerlat around the perimeter of the house - for this, a square beam with a side of 100 millimeters is used.
Then the frame for the room is installed, the racks will perform the function of supports for the rafter system. For this, a beam of not so significant cross section should be used. Initially, it will be necessary to install vertical racks, which are located at the end and beginning of construction. Their fastening is made to longitudinal beams by means of stamped steel corners and self-tapping screws. In order to facilitate fasteners, it is recommended to use a screwdriver. Further, a jumper is laid over the racks, which is then fixed.
The walls of the house from aerated concrete can be made as even and strong as possible, since the quality of the attic floor will depend on this. Between the two arches you should pull a cord that should indicate a horizontal line. Arches should be mounted along the tightened rope, the distance between which is dictated by the installation method of the rafters. Arches are interconnected by jumpers fixed with stamped corners. The latter can be replaced with nail plates.
Conclusion
If you are interested in inexpensive houses made of aerated concrete, the prices of which can vary from 10,000 to 13,000 rubles per square meter, then you can ask what firms in the modern market are constructing such buildings. If you decide to do the work yourself, then after assembling the frame, you need to start installing the rafters. The timber for this is cut to the required length, and at the base a groove is cut for installation on the Mauerlat. The next step will be fixing the upper rafters, the difficulty in this lies in the need to comply with a certain angle.
As you can see, you can easily build a house with an attic from aerated concrete yourself.
