Answer:

Hello Larisa. 20-36 belongs to a series of houses - The project of the house was designed using gas silicate blocks . The house project you are considering, in which as a material bearing walls used ceramic block Cayman30, is listed in our catalog under the number . ceramic blocks Cayman30 outnumber gas silicate / aerated concrete blocks according to all the main characteristics: strength, heat saving. At the same time, the final costs will be lower when choosing ceramics.. For more details, see the cost comparison below. Cayman30 allows you to build country houses that meet all applicable standards, and in particular, those that meet SNiP "Thermal protection of buildings" for cities such as: Yekaterinburg, Novosibirsk, Permian, Krasnoyarsk, without weak link- layer insulation. House project for free . Cayman30

Let's compare the materials under consideration - gas silicate blocks and ceramic blocks in terms of characteristics and construction costs.

Looking ahead, I inform you that the construction of the house you are considering from ceramic block Kerakam Kaiman30, superior in all respects gas silicate block D500 , will be less expensive, the savings will be 114 052 rubles.

You can see the calculation in numbers at the end of this answer.

1. Strength.

The strength of wall materials is determined by the limiting pressure of the distributed load on the test sample and is characterized by the number of kilograms of force (kgf) applied to one square centimeter of the material surface.

So ceramic block Cayman30 has a strength grade M75, which means that one square centimeter is able to withstand a load equal to 75 kg.

The value of the strength grade of a gas silicate block with a density of 500 kg / m 3, y different manufacturers, ranges from M35 to M50. As a result, according to the instructions of the manufacturers of gas silicate blocks, every third row of masonry should be reinforced, as shown in the photo below.

Ceramic block masonry Kaiman 30 reinforced only at the corners of the building, per meter in each direction. For reinforcement, a basalt-plastic mesh is used, which is laid in the masonry joint. Labor-intensive chasing and subsequent covering of the reinforcement in the strobe with glue is not required.

Masonry mortar during the installation of ceramic blocks is applied only along the horizontal masonry seam. The bricklayer applies the solution immediately to one and a half to two meters of masonry and starts each next block along the groove-ridge. The laying is very fast.

When installing gas silicate blocks, the solution must also be applied to side surface blocks. It is obvious that the speed and laboriousness of masonry with this method of installation will only increase.

Also, for professional masons, sawing ceramic blocks is not a problem. For this purpose, it is used reciprocating saw, with the help of the same saw, they are sawn and gas silicate blocks. In each row of the wall, only one block is required to be cut.

2. The ability of the structures under consideration to resist heat transfer, i.e. keep the house warm in winter, cool in summer.

Below is a heat engineering calculation performed according to the methodology described in SNiP "Thermal protection of buildings".As well as the economic justification for the use of the Kaiman30 ceramic block when comparing the costs of building the house in question from gas silicate blocks.

To begin with, we determine the required thermal resistance for external walls residential buildings for the city of Dmitrov, as well as the thermal resistance created by the structures under consideration.

The ability of a structure to retain heat is determined by physical parameter as the thermal resistance of the structure ( R, m 2 *S/W).

Let us determine the degree-day of the heating period, °С ∙ day/year, according to the formula (SNiP "Thermal protection of buildings") for the city Dmitrov.

GSOP = (t in - t out)z out,

where,
t in- the design temperature of the internal air of the building, ° С, taken in the calculation of the enclosing structures of the groups of buildings indicated in table 3 (SNiP "Thermal protection of buildings"): according to pos. 1 - by minimum values optimum temperature corresponding buildings in accordance with GOST 30494 (in the range 20 - 22 °С);
t from- average outdoor temperature, °C in cold period, for Mr. Dmitrov meaning -3,1 °C;
z from- duration, days / year, of the heating period, adopted according to the set of rules for the period from average daily temperature outdoor air not more than 8 °C, for the city Dmitrov meaning 216 days.

GSOP \u003d (20- (-3.1)) * 216 \u003d 4,989.6 ° C * day.

The value of the required thermal resistance for the external walls of residential buildings is determined by the formula (SNiP "Thermal protection of buildings)

R tr 0 \u003d a * GSOP + b

where,
R tr 0- required thermal resistance;
a and b- coefficients, the values ​​of which should be taken according to table No. 3 of SNiP "Thermal protection of buildings" for the corresponding groups of buildings, for residential buildings the value a should be taken equal to 0.00035, the value b - 1,4

R tr 0 \u003d 0.00035 * 4 989.6 + 1.4 \u003d 3.1464 m 2 * C / W

The formula for calculating the conditional thermal resistance of the structure under consideration:

R0 = Σ δ n /λ n + 0,158

Where,
Σ – symbol of summation of layers for multilayer structures;
δ - layer thickness in meters;
λ - coefficient of thermal conductivity of the layer material under the condition of operational humidity;
n- layer number (for multilayer structures);
0.158 is a correction factor, which can be taken as a constant for simplicity.

Formula for calculating the reduced thermal resistance.

R r 0 \u003d R 0 x r

Where,
r- coefficient of thermal engineering homogeneity of structures with heterogeneous sections (joints, heat-conducting inclusions, vestibules, etc.)

according to standard STO 00044807-001-2006 according to Table No. 8, the value of the coefficient of thermal uniformity r for masonry of large-format hollow porous ceramic stones and gas silicate blocks should be taken equal to 0,98 .

At the same time, I draw your attention to the fact that this coefficient does not take into account the fact that

1. we recommend laying with warm masonry mortar(this significantly levels the heterogeneity at the joints);
2. as connections between the bearing wall and the front masonry, we use not metal, but basalt-plastic connections, which conduct heat literally 100 times less than steel connections (this significantly eliminates the inhomogeneities formed due to heat-conducting inclusions);
3. window slopes and doorways, according to our project documentation they are additionally insulated with extruded polystyrene foam (which eliminates heterogeneity in places of window and door openings, vestibules).

From which we can conclude - when fulfilling the requirements of our working documentation, the masonry uniformity coefficient tends to unity. But in the calculation of the reduced thermal resistance R r 0 we will still use the tabular value of 0.98.

R r 0 must be greater than or equal to R 0 required.

We determine the operating mode of the building in order to understand what thermal conductivity coefficient λ a or λ in taken when calculating the conditional thermal resistance.

The procedure for determining the operating mode is described in detail in SNiP "Thermal protection of buildings" . Based on the specified normative document Let's follow the step by step instructions. 1st step. Let's define hmoisture content of the building region - Dmitrov using Appendix B of SNiP "Thermal protection of buildings".

According to the city table Dmitrov located in zone 2 (normal climate). We accept the value 2 - normal climate. 2nd step. According to Table No. 1 of SNiP "Thermal protection of buildings" we determine the humidity regime in the room. At the same time, I would like to draw your attention to heating season humidity in the room drops to 15-20%. During the heating season, air humidity must be raised to at least 35-40%. Humidity of 40-50% is considered comfortable for a person. In order to raise the level of humidity, it is necessary to ventilate the room, you can use humidifiers, installation of an aquarium will help.

According to Table 1, the humidity regime in the room during the heating period at an air temperature of 12 to 24 degrees and a relative humidity of up to 50% - dry. 3rd step. According to Table No. 2 of SNiP "Thermal protection of buildings" we determine the operating conditions. To do this, we find the intersection of the line with the value of the humidity regime in the room, in our case it is dry, with humidity column for city Dmitrov, as explained earlier, is the value normal.

Summary. According to the methodology of SNiP "Thermal protection of buildings" in the calculation of conditional thermal resistance ( R0) should apply the value under operating conditions BUT, i.e. it is necessary to use the coefficient of thermal conductivity λ a.

Answer:

In the project documentation for the house 95-25 ceramic block laid Kerakam Cayman30.

The total cost will be lower when choosing a more technologically advanced ceramic block Kerakam Cayman30. More details below.

Application of ceramic blocks Cayman30 allows you to build country houses that meet all applicable standards, and in particular, those that meet SNiP "Thermal protection of buildings" for cities such as Yekaterinburg, Novosibirsk, Perm, Krasnoyarsk, without inclusion in the design of the external wall weak link- layer insulation.

At the same time, the cost of building one square meter of housing will be one of the lowest when compared with any stone block, including in comparison with gas silicate blocks.

Projects of houses from ceramic blocks are included in the action House project for free .

Under the terms of the promotion when buying ceramic blocks Cayman30 in our company we will refund you the cost of the project documentation paid by you.

What is the difference between modern Caiman30 heat-efficient ceramic blocks and conventional ceramic blocks:

1. The large format block is a honeycomb structure where the air is in bound state, in closed chambers. Air, without the possibility of movement, acts as an excellent heat insulator. As a result, when determining the heat-saving capacity of a particular block, it is not the overall size that is decisive, but the length of the ceramic track. Heat from the house will go through the maze ceramic tracks each of the considered blocks. Pay attention to the lattices of the two blocks in question, in a more modern block Cayman30, the path that the heat flow will have to overcome is longer;
2. Pay attention to the fact that the track at the block Cayman30 has a smaller thickness than the block Rauf38 Therme. Obviously, this also contributes to the preservation of heat in the house;
3. At Cayman30 compressive strength grade is lower than that of Rauf38 Therme, this is due to the fact that Cayman30 the porization of the clay itself is higher, and this also contributes to the preservation of heat in the house in winter and comfortable coolness in summer, while for 2 storey building strength grades M75 more than enough. Blocks Cayman30 can be used in the construction of a house with up to 5 storeys;
4. And finally, the last, patented know-how, in the block design Cayman30, this is a heat-efficient lock of side docking of blocks. At the blocks Cayman30 the castle is a long sawtooth path for heat to escape from the house. In an outdated model of a ceramic block, one of the samples of which is Rauf38 Therme, the heat in the castle flows away along a straight and thick path.

All projects included in the action Project of a house for free are presented on the page

Projects of houses with a bay window are often found on the Alfaplan website. Such developments are always a success with customers, which is not difficult to understand. A house with a bay window looks romantic and original, small extensions give it a unique charm. And inside the room looks even better - it has more space, more light, more comfort and style.

A bay window is a small (and sometimes quite large) external ledge in a wall. The bay window can be located both on the first and on the second or third floor of the cottage. It can be round, square, triangular or polyhedral.

House with a bay window - additional features and unusual solutions

Original projects of houses with a round or square bay window are in constant demand from our customers. This architectural element is a part of the building - a columnar or polygonal ledge that extends beyond the boundaries of the facade and is glazed on all sides. He gives anyone, even himself simple building, elegant look.

Stylish modern facade

The prototype of the bay window can be called watchtowers that vaguely resemble it, which were built in medieval castles. Niches open on three sides made it possible to notice the approaching enemy from afar. Over time, they lost their combat value, and became an element of decor. AT gothic architecture it was called a "lantern", in Russian architecture hexagonal "drums" were common.

AT modern projects cottages with one or two bay windows in front, columns, they are assigned not only a decorative, but also a functional role. They improve the insolation of the building, especially with north side where the sun enters the side windows from the east in the morning and from the west in the evening. They are often built several stories high - this technique is used in buildings with a second light.

Our architectural solutions

Our catalog contains photos of cottages with full documentation different area, with attic, balcony and others interesting elements. They are built from different building materials.

• Projects of wooden houses with a bay window made of logs, glued beams. As an example, we can cite a building stylized as a “Russian Estate” - photo No. 10-33 with a protruding part of the building in the form of an elongated rectangle. No less interesting is option No. 10-25 with a triangular ledge in a modern style.
• Cottages with brick and combined walls. The plasticity of this material allows you to create facades complex shape. The catalog includes many such buildings, for example: No. 48-21 with a semicircular and No. 48-24K with a square ledge.
• Projects 2 storey houses with an oval or rectangular bay window made of aerated concrete, foam blocks, gas silicate blocks. These economical materials are widely used in modern construction. A sample of such a cottage is shown under No. 48-31G.

Facades with a porch in the form of a bay window, or with its location in the corner part, look very stylish and modern. They focus attention on themselves, forming the compositional center of the architectural ensemble.
