Calculate the estimate for the construction of a house from foam blocks. Estimate for the construction of a gas-concrete house with siding, monolithic slab foundation, wooden-beam flooring, corrugated roofing

You need to be able to correctly determine your financial costs so that you do not have to overpay for unnecessary and additional services of construction organizations. You just use the calculator for building a house from foam blocks and get data that is close to real. In accordance with the results you invest in the construction of the facility.

The estimate for a standard house of foam blocks. Foundation

If you plan to build a house from a foam concrete block with dimensions of 6 by 8 meters, and there is a terrace and 3 residential premises. There is also a kitchen in the building. You need to build a box of, but before that, make a number of important calculations.

Suitable as a foundation for such a structure, but at the same time it is necessary to choose the depth of depth correctly, depending on the characteristics of the soil and the parameters of the building.

Since foam concrete blocks are a building material with a small weight, a depth of up to 0.5 meters is allowed, provided that we are dealing with sandy or clay soil. If you make a deeper strip foundation, then there is the opportunity for a basement or cellar.

By design, the foundation for an object of foam concrete blocks can be:

• Buried
• Shallow,
• Capless
• National team.

The most reliable design is a monolithic type, so you should choose it. And the cost of materials on the foundation must be included in the total cost of. Basically, a large amount of cement and sand, as well as crushed stone, will be required.

The overall dimensions of the strip foundation are 200x300x600 mm, it must be taken into account that the base part will be connected to the formwork to ensure the construction is monolithic. The height of the tape together with the base part is 1 meter. To calculate the length of the foundation, you need to add all the lengths of the dug trench.

Now it remains to summarize and calculate the volume of concrete mixture that will be poured into the formwork: 50 (trench length) × 1m (height) × 0.5 (deepening) \u003d 25 cubic meters. For such purposes, quality concrete is used. One cubic meter of foundation should contain:

• 385 kg of cement,
• 220 liters of water
• 700 kg of sand
• 1000 rubble.

Having these figures at hand, the total volume of materials and the cost of the entire foundation are easily calculated. It is only necessary to take into account the reinforcement and enter the data into the calculator for building a house from foam blocks about the reinforcement used.

Before the floor is poured, a similar calculation of the concrete mixture is performed, as in the case of the foundation.

Number of foam concrete blocks for walls

Almost any house has load-bearing walls and interior partitions, and they differ in design features. If it is recommended to use masonry in half a brick for bearing walls from a foam block, then a quarter is sufficient for partitions. The lateral part of the foam concrete block is 200 × 300 \u003d 0.06 meters, the bed 300 × 600 \u003d 0.18 meters.

Before using the calculator for building a house from foam blocks, you need to determine the height of the walls, which can be 2.8 meters or higher. For a height of 2.8 meters, foam blocks in the amount of 14 pieces will be required, with the seams being 0.5 cm. Therefore, given the fact that the laying of the bearing walls is done in half a brick, we get 2.87 m.

The room usually includes floor and ceiling coverings that take up usable area, so that the height may change in the direction of reduction. The area of \u200b\u200bthe bearing walls is calculated using the expression (8 + 8 + 7.3 + 6 + 4 + 1.3) × 2.8 \u003d 96.88 square meters. And if this value is multiplied by the area of \u200b\u200bthe foam concrete block, then the amount of 1615 stones is obtained.

Knowing the number of partitions and their height, the area is easily calculated: (8 + 3 + 3) × 2.8 \u003d 39.2 square meters. Now you need to multiply this result by a quarter of a brick and you get 218 stones.

In the calculator of building a house from foam blocks, data should be entered on the amount of special glue that will be required for both external walls and internal.

For these purposes, it is necessary to use the length of all the walls and find out how many joints will turn out, both in the horizontal and vertical directions. The thickness of the adhesive layer is usually 0.005 m.

Foam masonry with brick finish and internal thermal insulation

Foam masonry

Today, foam concrete is a fairly common, environmentally friendly and inexpensive building material, which is characterized by significant vapor permeability and porosity, in comparison with other brick blocks.

Due to the nuances of the manufacturing process, foam concrete blocks compared to aerated concreteAs a rule, they exhibit quite noticeable size errors, which is why they are laid out on a traditional sand-cement mortar. However, the presence of thick binder joints between the foam concrete blocks, in addition to overstating the installation cost, leads to the appearance of foci of heat loss and weakening of the insulating characteristics of the wall.

Plastering the foam block wall can be done only after 6-9 months (in some cases, and after a season), due to significant shrinkage of the foam blocks - up to 2-3 mm / m and the possible cracking of the plaster layer, taking this into account, for the fast finishing of the internal walls of foam concrete In homes it is generally recommended that gypsum or drywall panels be used.

According to existing standards, for the Central Russian climatic zone, a single-row outer wall of foam concrete blocks 40 cm thick with an outer glass wool thermal insulation, fifty millimeters thick, is enough.

In terms of fire protection, thermal insulation, acoustic protection, foam concrete is much superior to solid brick.

Exterior walls of foam concrete should not block the output of water vapor from the rooms to the outside. Therefore, it is unacceptable to paint foam-concrete walls with film-forming agents, plaster with cement mortar, and cover with polystyrene foam plates.

When installing foam block masonry, it is important to take into account a lot of requirements and construction features, otherwise, instead of reducing the cost of materials, it is really possible to find a bit too cool, damp, or completely cracked structures.

• To install the reinforcement rods, on the surface of the laid foam blocks, the strobes are cut with a shtroborez to a depth and width of 3 * 3 cm, which, when mounting the reinforcement, are filled with glue for foam concrete blocks.
• According to the installation instructions, it is necessary to reinforce with fiberglass nets every 4-5 rows of blocks, as well as places for supporting jumpers and places under window openings.
• The installation of the lower row of foam blocks should be treated as carefully as possible, checking the vertical and horizontal masonry along the level during installation.
• Foam concrete blocks are fairly easy to mill, saw with a hacksaw, planing, drilling, ditching directly at the construction site.
• A non-standard or slightly protruding block should be aligned with a plane to the required level at the place of its installation.
• Reinforced concrete blocks with a thickness of up to 20 cm are made on top of foam concrete blocks in wooden formwork preparation. The concrete screed is insulated with a 5 cm layer of extruded foam on the outside.

Facade brick cladding

Facade brick is perhaps the most famous wall material for building walls, which, in addition to its classic appearance, is characterized by large (up to a hundred periods of freezing-thawing) frost resistance and low (less than 6%) moisture absorption, which determines the long life of brick households. In addition to the usual, among the facing and facade clay brick materials there are clinker, glazed and figured bricks.

Nowadays, facade bricks of all kinds of profiles (beveled, rectangular, wedge-shaped, rounded) and reliefs (rough, smooth, chipped, corrugated), as well as colors (from light yellow to dark brown) are implemented, which allows for the implementation of various innovative architectural designs .

• The main wall of foam concrete, with an external heat-insulating coating, is insulated from the brick wall with a slit of 20-50 mm, over the entire height of the wall, to remove moisture, with the device of input / output openings at the bottom and top of the facade.
• The front wall is carried out in spoon rows on a sand-cement binder, with every 4 rows of spoons ligated with a row of pitches.
• From the outside, pieces of basalt thermal insulation (for example, Ursa, Izomin, Isover, Izorok, Rockwool, Knauf), 5 cm thick, are hung on the foam concrete using plastic anchor dowels, over which a vapor-permeable waterproofing film is stretched, such as Tyvek, Yutavek, Izospan.
• Since there is a risk of shrinkage cracks, it is impossible to bandage the brick and foam block parts of the wall with inflexible steel nets embedded in the seams of the walls.
• Since the foam-block and brick parts of the wall have an unequal degree of shrinkage, the bonding of the foam-block and facing wall structures is done by laying 2-3 rows of blocks using soft fiberglass mesh or non-rigid galvanized plates.

Foundation of reinforced concrete slab and monolithic tape

The slab foundation is arranged over the entire area of \u200b\u200bthe structure in the form of a monolithic reinforced concrete slab and can be in a buried or not buried design.

When deepening, the foundation slab serves as the basis on which the vertical parts of the foundation are erected, which form the underground floor. At the upper groundwater level, it is recommended to erect the vertical walls of the foundation by the method of inextricable concreting, with the use of waterproofing coatings: coating, impregnation, gluing.

An undecked slab base is used in private buildings, on unstable soils: bulk, peat bogs, reclaimed or heavily steep and wetland areas. Such a foundation is recommended when erecting utility structures that do not have a high above-ground part of the foundation and basement storage.

In practice, when the top of the foundation slab is used as a base for the floor construction of the dwelling, and therefore the foundation slab is placed above the freezing mark of the earth, there is a need for thermal insulation of the earth under the foundation slab and strip, 100 ... 150 cm wide around the perimeter.

It is considered appropriate to install sheets of extruded polystyrene foam (for example: Ursa XPS, Primaplex, Styrodur, Teplex, Penoplex, Polispen, Styrofoam, Technoplex), due to the fact that other heat-saving agents: glass wool, polystyrene foam, expanded clay - have significant moisture absorption, which leads to to a transient drop in their heat-insulating properties in water-saturated soil.

Approximate technology for a single-plate foundation with lateral parts in the form of an inextricable reinforced concrete perimeter:

• The first step is to remove the layer of earth to the design depth.
• crushed stone is poured, with a grain size of 40/60, a thickness of 15-20 cm, and carefully packed.
• A cement-sand layer is produced, up to 5 cm high.
• A moisture-proof film is applied with the release along the external line of 2000 mm, for vertical moisture insulation of the walls of the foundation base.
• To protect the waterproofing membrane from accidental cuts during the reinforcement process, the next layer of cement-sand mortar, up to 50 mm high, is made along the insulation coating along the perimeter of which formwork panels are placed along the height of the base plate.
• The manufactured plate is reinforced with two gratings from steel rods of diameter d14 of the А300-А400 grade with cells of 20x20 cm.
• In the case of a solid foundation, only high-quality concrete is suitable, grades no lower than M300, transported by a concrete truck.
• Indented 200 ... 250 mm from the edges of the foundation slab, formwork is placed along the height of the vertical parts in the form of a solid w / concrete tape,
• A reinforcing belt assembled from reinforcing bars of the AIII Ø12 grade is placed in the finished formwork form, and a concrete mortar is made.
• The hardening period of the concrete mass (when the formwork should be removed) takes, in practice, one month in the warm season.

Overlap from a monolithic reinforced concrete slab

The device of molded reinforced concrete interfloor overlapping, in the practice of individual housebuilding, is acceptable only in cases where it is difficult to use standard reinforced concrete products, for example: places that are too remote for trucks or complex building ensembles.

The technology for the construction of a reinforced concrete slab includes the following mandatory stages: installation of the formwork structure, placement of the reinforcing cage and pouring concrete mixture. At the same time, builders will be required to clearly carry out technological calculations in terms of cross sections of reinforcing steel and the composition of the concrete mixture, as well as the rental of special equipment and the availability of practical knowledge.

Because solid concrete floors have a very tangible weight, it is permissible to arrange them only in brick-block buildings with capital prefabricated-block, strip and slab foundation foundations.

The structural components of the reinforced concrete floor are specified by the design solution, while in most cases, the height of the slab is considered to be at least 3.3% of the length of the floor.

It should be noted the main points in the construction of a concrete floor panel (span length of not more than 600 cm, floor thickness - 200 mm):

• Since the formwork structure must withstand the load of the poured concrete mixture, about 1/2 ton per m & sup2, it is advisable to use painted plywood, about 2.0 cm thick, backed by supports from metal pipes, to fill the floor, d Ø45 ... 50 mm, or racks made of wood, the base of 100x100 mm.
• By means of a steel wire rod of type d2 Вр-1, with a gap from the edges of the casting form - at least 40 mm, two mesh tiers, lower and upper, are connected from reinforcing bars, type А400 (A-III), А500 D 12 mm. Reinforcing mesh ligaments are divided relative to each other according to level, within the panel thickness, using prefabricated standing ribs from reinforcement with bent end parts.
• In order to make closing concrete shells at the top and bottom, the reinforcing steel frame should be 5.0 ÷ 6.0 cm thinner than the formwork structure, i.e., be in the volume of the slab. for this purpose, the mesh below is installed on plastic linings with a height of 25 ... 30 mm, and the overlying mesh, when concreted, is poured with concrete mix, the same height layer.
• It is worth considering that concrete for laying must be performed on high-quality, fine particles, aggregates and have a strength class of M250 ... M400, so the best choice is the acquisition of concrete of industrial origin.
• It is necessary to make concreting in one shift, until the concrete mortar begins to harden.
• For the full hardening of a concreted monolithic panel, it is important to create an optimal heat-humidity environment. It is allowed to remove the formwork only after 30 calendar days.

Metal roof

Monterrey tiled format is considered to be the leader in sales today on the market: wave period - 0.35 m, wave depth - 2.3 cm, realized by different industries (Pelti ja Rauta, Poimukate, Finish Profiles, Interprofil, Grand Line, Metal Profile).

The roof is mounted on a supporting base, consisting of roof trusses and a pre-slab beam crate.

In the construction of individual buildings, a scheme of 2 and 3 spans with inclined rafter elements and internal supports is often used.

The distance between the rafters is set within 600 ... 900 mm with a frame size of rafters 50x150 ... 100x150 mm; the supporting ends of the rafter beams are lowered onto the Mauerlat with a section of 100x100 ... 150x150 mm.

In order to reliably weather the moisture arising from the dwelling and protect m / tiles from the possible occurrence of rust, the total cross-section of the channels for ventilation: ductile and exhaust, is calculated by the formula: 1: 100 to the roof area.

Important points of fastening of cloths m / tiles:

• Before assembling the battens, it is recommended to lay diffusion fabric on the rafters: TechnoNIKOL, Stroizol SD130, Tyvek, Izospan, Yutavek 115.135, for further insulation of the attic space. It is not allowed to use non-porous films for waterproofing, for example, on a bitumen basis.
• On trusses of trusses, on the fixed waterproofing material, bars of 3.0 x 5.0 cm are packed, and to them a battens of boards 10 x 3.0 cm, with an interval of 35 cm (for the Monterrey, Joker profile). At the same time, the first crate is placed in a larger section (2 cm), and the distance between the beginning of the very first board and the midpoint of the next should be 30 cm.
• When performing the crate preparation, in places of further installation of the snow-retaining structure, reinforcing crates should also be placed under the profile lift.
• Before the flooring of the strips of m / tile, the gutter holders are fixed to the cornice or truss beams.
• Stripes of steel tiles are attached to the profile deflection, in the areas of bearing on the crate.
• To the initial sheathing, which has the greatest thickness, the steel tile sheets are pressed with self-tapping screws above the steps of the wave.
• Extreme left and right roofs, strips are attached along the boundaries of the roof even more often, i.e. on all support bars.
• When installing metal tiles, the first sheet is exposed along the end and the bottom line of the roof and hung on one self-tapping screw to the ridge battens, they are also engaged with two or three next sheets in a row, linking them together and aligning along the eaves line, and only then firmly fixed, while spending about 6-8 pcs. tiled self-tapping screws with sealing washers per square meter of the roof.
• Laying of metal tile sheets is carried out, from bottom to top, in an arbitrary horizontal direction, taking into account the fact that each subsequent strip covers one period and the previous capillary drain.

Before calculating the cost of materials and making an estimate, it is reasonable to talk about the material itself from which construction is planned. The material in question is classified as lightweight concrete blocks.

Lightweight building blocks are divided into three types of building materials:

• Foam concrete   - the composition of this material includes two elements - this is a cement mixture with the addition of sand and a chemical reagent with which foam is formed. In order to give the resulting solution the desired shape, it is poured into special forms in which the process of heating it occurs. This material is easy to manufacture, so its production can occur during the construction process, directly on the construction site.
• Aerated concrete or cellular   - this material differs in its properties from foam concrete, for its hardening requires high humidity and high temperature. The advantages of this material include the fact that only environmentally friendly materials are used for its manufacture. The composition includes: water, sand, lime and cement. The structure of such a material will be durable and strong, as well as the material is not susceptible to combustion and lends itself well to machining. Aerated concrete stands on one step with a tree in terms of its environmental performance.
• Expanded clay   - The most common type of lightweight concrete.

This material is highly competitive in the modern construction market. The main advantage of the material is its low weight, less construction time is spent during construction due to the convenience of working with light material.

In addition, aerated concrete houses are also popular because of their efficiency during operation. Profitability lies in the fact that for heating such a house does not require a lot of energy, which can not be said about brick houses.

Also, a house from aerated concrete can be built independently, without the help of specialists. And the delivery of material will not cause great difficulties for buyers.

If we consider the material from an environmental point of view, we can say for sure that it is environmentally friendly. No toxic substances, gases and suspension are released from it. Thus, the material is completely safe for the environment.

When laying the material, there will also be no difficulties. Due to the fact that it is of the correct form, there will be no difficulties with the seams, and they will not be more than 4 mm. Aerated concrete retains heat well, so during the construction of it there is no need for thick walls.

Pricing policy for the construction of a house from aerated concrete

The price of the building will depend on two indicators - this is the density of the material and the thickness of the walls. Accordingly, with an increase in parameters, the price will increase, and, conversely, with a decrease, the price will be less.

On average in Russia, the project of such a house with an area of \u200b\u200b350 square meters is 30 thousand per square meter.   And since it is easy to work with the material, there is no need to hire qualified specialists for its installation, and this will significantly reduce construction costs.

The type of foundation used in the construction of foam blocks and aerated concrete

Before you begin construction, you must select a place for the building. Using official documents, it is necessary to find out the type of soil and the depth of groundwater, and from these data to determine what foundation is needed for the selected territory.

If the type of foundation is chosen correctly, then the structure will stand for a long time, and will not deform and collapse. The type of foundation will partly depend on the price of the building.

Construction stages

1. The first step in building a house   is laying the foundation.
2. The second step is the construction of walls. Before the construction of the walls, it is necessary to make waterproofing so that the house does not freeze.
3. The third step is reinforcing aerated concrete. The mesh is laid between the finishing layers to prevent deformation of the structure.
4. The following is the installation of floors.
5. Construction is nearing completion   interior and exterior decoration.

Foam concrete masonry

Recently, material such as foam concrete has become very popular. The reason for this was the fact that this material is hygienic and has a low cost. Unlike other concrete materials, it has good vapor conductivity and capillarity.

Foam concrete differs from aerated concrete in that size errors may occur during installation, this is due to the technology of its production. It is for this reason that foam concrete is laid on a sand-cement mixture.

In the middle lane during the construction of the house, it is necessary to erect one wall of foam concrete, which should be about forty centimeters and covered with a glass wool heat shield on the front side. The thickness of the heat shield should be five centimeters.

If we talk about foam concrete from a safety standpoint, then it is significantly ahead of brick materials in its qualities.

Finishing a structure erected from foam blocks can be done at least six months after the end of construction.

It is necessary to do this because the foam concrete is reduced in size and because of this the finishing layer is destroyed. For the finishing layer, it is best to use drywall.

When finishing a building from foam concrete outside, it is necessary to select a material that will allow the passage of fumes from the premises of the house.

Important! Exterior finish of the building from foam blocks cannot be made using a film-forming composition, as well as plastering.

Brick facade

A fairly optimal option for the design of the structure is the front brick. Brick is the oldest material used to build houses.

The use of brick was due to the fact that it is quite durable and has little water absorption. Brick is also suitable for the implementation of various design ideas. It is available in various shapes and textures.

The following brick forms are currently available:

• rectangular;
• rounded
• wedge-shaped;
• beveled.

If we consider the invoices, we can indicate the following:

• corrugated;
• rough
• smooth;
• pounded.

With such a variety of shapes and textures, it is possible to realize any design idea and imagination.

Slab concrete foundation with monolithic concrete strip

The slab foundation is a reinforced concrete slab, which is installed along the outer perimeter of the walls of the building.

There are two options for installing a slab foundation:

• Not deep
• In-depth.

If the slab foundation is placed according to the second option, then it also acts as the foundation for the structure. The foundation walls are placed on this base, and an underground floor is formed. The method of continuous concreting for vertical parts of the foundation is used for shallow groundwater. In this case, it is necessary to carry out waterproofing measures.

If the soil is unstable or near groundwater, then an undepaved slab base is used. Such buildings are advisable if you do not need a basement or cellar. Such a slab base is suitable for small buildings.

Important! There is a chance of freezing the foundation if the foundation slabs serve as the basis for the floor of the room and are above the freezing point of the ground.

To prevent freezing of the soil, it is necessary to make thermal insulation. Insulation is done under the base plate around the entire perimeter of the room. The strip of insulating material must be at least one hundred centimeters.

A good option for the insulating material is a heat shield, which is made of extruded polystyrene. Such a screen is better than other heaters in its properties, such as glass wool, expanded clay granules and granular polystyrene, as it absorbs moisture poorly and retains its heat-insulating properties for a long time.

Prefabricated reinforced concrete slabs

Reinforced concrete slabs are usually used to create interfloor ceilings in brick houses. Plates are hollow.

The use of such plates is due to their positive qualities. They soundproof well, unlike reinforced concrete floors.

Ceilings are made using a special technology in which the initial reinforcement of concrete is produced, and the ceilings become more load-lifting, unlike those that are immediately made at a construction site.

Plates manufactured by industrial technology, guarantee the specified operational properties and have a low price. Such overlappings are much faster to install.

Steel roof

Steel roof tiles are currently the most common material for the manufacture of roofs. For the buyer, its acquisition will not create any difficulties, since it is produced by a large number of manufacturers. To install the roof, a strong frame is constructed, which consists of a crate layer and rafter elements.

The roof of the tiles can be made with a different number of spans. For a private house, a two or three-span system is most often used. In such a system, internal load-bearing walls are erected, as well as rafters at an angle.

The base on which the rafters are mounted is called Mauerlat. Between the rafters, it is necessary to make an interval that varies in the range from 60 to 90 centimeters, if the thickness of the beam is 100 * 150 mm.

In the roof, it is necessary to make ventilation channels that will remove moisture from the premises of the building. The number of such channels depends on the area of \u200b\u200bthe roof and is 1/100.

Double-pane windows made of wood
