We understand how important it is to live in silence: not to hear neighbors or street noise, to sleep peacefully when there is a holiday outside the window. Therefore, the Melikonpolar company has developed special stones for the construction of quiet interior and apartment partitions. When developing the design of the stones, we were guided not only by the requirements of the Building Code for sound insulation, but also by simple, everyday human needs. The stones we have developed for apartment and interior partitions meet the highest standards of quality and comfort of life:

• The airborne noise insulation index of PK-160 (52 dB), SKTs 1R-1pg (54 dB) and SKTs 2R-19 (45 dB) meets the highest requirements of SNiP 23-03 “Noise Protection”;
• PK-160, SKTs 1R-1pg and SKTs 2R-19 are made of concrete with strength M 200, which ensures vandal resistance of the partitions and protection from accidental damage;
• The high strength of the partitions allows you to fearlessly attach any hanging structures to them without special fasteners;
• The surface of the stones has good adhesion and is easy to plaster;
• If you install the partitions yourself, you will be pleased with the light weight of the stones and the thoughtfulness of the design: the stones are laid empty down, which prevents the mortar from falling through; the vertical seam is made dry (without mortar) and has a tongue-and-groove connection system.

Inter-apartment PC-160

• Concrete stone PK - 160 is intended for the construction of inter-apartment partitions in houses of all categories;
• The airborne noise insulation index of PC - 160 is 52 dB with a thickness of only 16 cm, which satisfies the main requirements for inter-apartment partitions;
• The thickness of the stone is 160 mm, allowing you to increase the area of ​​the interior (compared to thicker brick partitions);
• PC - 160 has a single module with the most common thickness of monolithic walls, which allows you to fill openings without creating additional protrusions on the wall;
• The double tongue-and-groove system significantly increases the reliability of the vertical connection of stones, which is performed dry, without mortar, reducing the time and labor intensity of construction;
• The stone is laid hollow down, the top surface is solid, which prevents the mortar from falling into the voids.

3. INSTALLATION OF INTERIOR PARTITIONS FROM CONCRETE

HOLLOW STONES

3.1 When designing, the dimensions of the stone should be taken into account so that the width and/or height of the walls and piers is a multiple of the whole and/or half stone. The stone can be sawn to the required dimensions, provided that the stiffening ribs are preserved. Calculation of the maximum wall height is carried out according to paragraphs. 6.16 – 6.20 SNiP II-22-81.

The regulatory requirements for the airborne noise insulation index (Rw) are achieved by correctly performing the following work:

Joining stones (clause 3.3-3.14, p. 8-10)

Connection contours (clause – 3.18, p. 13)

Grilling, installation of sockets (clause -3.19, p. 13-14)

Installation of sockets (clause -3.20, page 14-15)

3.2 Before starting work on laying partitions, it is necessary to clean the base of the adjacent structure from dust and dirt. The surface of the base is leveled or the levelness of the reinforced concrete floor is checked.

3.3 According to the project, it is necessary to mark the position of the structure being erected on the floor and, using a plumb line, transfer it to the walls and ceiling. For convenience, beacon strips can be installed along the walls.

–  –  –

TECHNOLOGICAL MAP FOR INSTALLATION OF PARTITIONS

The joining of stones is carried out by combining the groove and ridge from top to bottom. It is unacceptable for the mortar mixture to get into the vertical joint.

–  –  –

3.4 The laying of stones is carried out in a staggered manner by joining the groove and the ridge of the stones being laid with the voids facing down. Laying stones with the voids facing up and filling the voids with a mortar mixture may only be used in places pre-designated in the project for fastening the dowel structure.

3.5 The spacing between vertical joints must be at least 90 mm and no more than 310 mm - for SKTs 2R-19. Distances in order between vertical seams of one row for additional stones are not standardized. The strength of the masonry is achieved by observing the rules of order. In corners and places where walls intersect with each other, stones must be laid so that they alternately overlap the joints of the lower rows, ensuring ligation.

3.6 The stone is sawn with an electric circular saw with a diamond blade for concrete (dry cut), or additional stone is used to achieve the required dimensions. Halves can be obtained by splitting a special stone with a through void in the middle.

3.7 The masonry of floor partitions is divided into 3 tiers, the height of each of which is no more than 1.2 m. The walls of the first tier are laid from the floor slab, the second and third tiers - from the scaffolding.

3.8 The thickness of horizontal joints should be 10 (+/-2) mm. For the first row, the thickness of the leveling continuous mortar joint can vary from 6 to 30 mm depending on the surface of the base.

3.9 Vertical connection of whole stones is carried out without mortar, by joining the groove and ridge of the stones being laid and grouting the joints on both sides with a mortar mixture.

–  –  –

TECHNOLOGICAL MAP FOR INSTALLATION OF PARTITIONS

3.10 A vertical seam is made with a solution only in the case of joining:

Two sawn stones.

One sawn and whole stones.

In this case, the thickness of the vertical seam should not be more than 15 mm.

3.11 The junctions of the partitions with the main frame of the building are carried out in accordance with the working drawings of the project. The vertical seam at the junction of the masonry with walls or columns is filled with masonry mortar up to 30 mm thick.

In the absence of design solutions, stones are rigidly attached to load-bearing structures using pieces of metal or basalt-plastic reinforcement with a diameter of 8 - 10 mm and a length of 200-300 mm (Fig. 8).

Figure 8.

3.13 Attaching partitions to walls must be done evenly in height in at least four places for each connection.

3.14 If necessary, fastening the partitions to the floors is carried out through a mortgage (galvanized punched tape), which is inserted into the groove to the full height of a whole stone and clamped with the ridge of the next whole stone with a mandatory vertical mortar seam. The fastening pitch is set based on fastening through five stones.

3.15 If longitudinal reinforcement is required, reinforcement with a diameter of 6 mm is laid along the entire length of the partition in the mortar joint of every fourth row of masonry. In this case, the reinforcement is laid in such a way that when laying the top row of stones, the rods fall into special grooves on the lower surface of the stone.

3.18 To prevent the occurrence of stresses in the masonry and ensure the soundproofing properties of the partition, a horizontal expansion joint with a thickness of 30 mm is provided. The gap formed upon completion of the work and drying of the masonry, between the last row of stones and the upper floor slab, is filled with elastic material and then grouted with mortar. For example, a polyethylene foam rope with a diameter of 30-40 mm. or foamed with polyurethane foam.

3.19 Installation of electrical and low-current wiring is carried out hidden, in the voids of the stone, in two ways:

Scoring on the wall. Performed with an electric circular saw. A round recess for the socket is drilled with a concrete crown of the appropriate diameter.

TECHNOLOGICAL MAP FOR INSTALLATION OF PARTITIONS

No gating. The design of the stone allows utility networks (preparation) to be laid through the voids during laying.

To do this, you need to break through a thin membrane of stone voids with a hammer in the place where the electrical cable will pass, then pass the cable through the blocks that fall on it.

Gouging with impact tools (perforator, chipper) is not allowed.

At large quantities vertical grooves, it is necessary to fasten the partition structure to the base wall and ceiling, ensuring the stability of the masonry.

To restore the soundproofing properties of the stone, it is necessary to rub the groove with a mortar mixture of at least M100 to a thickness of at least the thickness of the stone wall.

3.20 Output of sockets, switches, etc. is not allowed. on both sides of one stone at the same time (opposite each other), as required by SNiP 23-03-2003 “Protection from noise”. For such holes it is necessary to use adjacent stones.

Physico-mechanical characteristics of expanded clay concrete blocks (expanded clay blocks).

In terms of their physical and mechanical properties, our products meet the requirements of GOST 6133-99 “Concrete wall stones. Technical conditions.

Depending on their purpose and the composition of the concrete, expanded clay concrete blocks (expanded clay blocks) are divided into wall and partition blocks and into three groups and are directly related to their density (the amount of expanded clay and its fraction included in the expanded clay concrete blocks:

1. Thermal insulating expanded clay concrete is the least dense (has better thermal insulation properties and low weight).

2. Structural and thermal insulating expanded clay concrete (has average density, average thermal insulation properties and average weight).

3. Structural expanded clay concrete (has the highest density, therefore this material is the most durable and its thermal conductivity is quite high).

Our company produces all three types of blocks, with specified physical and mechanical characteristics presented in this section, on which their scope of application directly depends.

You can find information on areas of application on our website in the sections "Scope of application" And "Application experience".

First type: Blocks based on thermal insulating expanded clay concrete - the density of blocks of this type is about 500-900 kg/m3, the compressive strength of such material is 7-50 kg/cm2. The thermal conductivity of such expanded clay concrete is approximately 0.14-0.25 W/(m*K).

Expanded clay concrete blocks (lightweight) containing at least 70% expanded clay.

Block marking and designation

The symbol for wall stones in accordance with GOST 6133-99 should consist of the abbreviated designation of the stone - K, its scope and purpose (S - for laying walls or P - for partitions; L - front or R - ordinary), the type of stone in terms of its use in masonry (PR - serial, UG - corner, PZ - dressing) and the presence of voids (PS - hollow), length in centimeters, strength grade, frost resistance grade, average density and state standard designation.

An example of a symbol for a standard row hollow wall stone, 390 mm long, strength grade 100, frost resistance grade F75 and average density 1400 kg/m3: KSR-PR-PS-39-100-F75-1400

Analysis of the properties of wall blocks:

Thermal conductivity - the ability to transfer heat from hotter areas to colder ones. Thermal conductivity is quantitatively determined by the thermal conductivity coefficient (λ), which expresses the amount of heat passing through a sample of material with a thickness of 1 m and an area of ​​1 sq.m with a temperature difference on opposite surfaces of 1 ° C in one hour. The value of thermal conductivity is influenced by the density of the material, the type, size and location of voids. The thermal conductivity of a material is directly dependent on its chemical composition, porosity, humidity and temperature at which heat transfer occurs. The thermal conductivity of the material is important when constructing building envelopes - walls, ceilings, floors, roofs. Light and porous materials have little thermal conductivity. The higher the density of the material, the higher its thermal conductivity.

Knowing the thermal conductivity coefficient (λ) of the material, it is easy to calculate the thickness of the walls of your facility.

In accordance with SNiP 23-02-2003 “Thermal protection of buildings”, there is a standardized value for the heat transfer resistance of enclosing structures, which depends on the climatic conditions of the area (degree-days of the heating season) and the type of building.

Strength - the ability of a material to resist destruction under loads. In buildings and structures, materials experience compression, tension, bending, shear, torsion, abrasion, and a combination of these loads. The strength of building materials is characterized by their tensile strength. Ultimate strength (MPa) is the stress corresponding to the load causing the destruction of the sample. The tensile strength of various building materials ranges from 0.5 to 1000 MPa or more. The tensile strength is determined experimentally using hydraulic presses or tensile testing machines and standard material samples. For some materials (concrete, brick), the tensile strength is determined by splitting cylinders or prisms.

The marking of the wall block in accordance with GOST 6133-99 must indicate the strength grade M, which shows what maximum pressure (kg/cm2) it can withstand.

Example: The wall block has a strength grade of M50. This means that it can withstand a pressure of 50 kg/cm2 or per block: 39cm x 19cm * 50 kg/cm2 = 37050 kg or 37.05 tons.

Frost resistance - the ability of a material in a water-saturated state to withstand repeated freezing and thawing without visible signs of destruction. Destruction occurs due to the fact that the water in the pores increases by about 9% when frozen. Testing building materials for frost resistance consists of cyclic alternating freezing and thawing in a water-saturated state and subsequent determination of the loss of mass and strength by the material. Freezing and then thawing the sample is one cycle; The cycle duration should not exceed 24 hours. The number of test cycles is taken in accordance with GOST for the material. A material is considered frost-resistant if, after establishing the number of freezing and thawing cycles in a water-saturated state, its strength has decreased by no more than 15-25%, and its weight loss has not exceeded 5%.

In terms of frost resistance, stones can be of the following grades and are indicated in cycles: F15; F25; F35; F50; F100; F150; F200.

Dear customers, regarding this parameter we would like to clarify the following, in practice there is often a misunderstanding of this parameter, that is, many people understand that 1 cycle = 1 year, this is not true, for example Frost resistance F100 or F35 means that 100 or 35 freezing cycles were carried out/ defrosting. According to the standards for blocks and our climatic region, it is enough to have an indicator of 35 - 50 cycles, and most manufacturers stop their tests at this figure. This does not mean that these blocks will collapse during further testing, and the F100 characteristic is a fairly high indicator; it meets the requirements for facing bricks, since the brick is in direct contact with the environment and is in no way protected from rain and snow.

Density - is called the mass of a unit volume of a material. To calculate the density r (kg/m3), you need to know the mass of the material m (kg) and its volume V (m3).

Most building materials are porous materials, i.e. in their volume, in addition to the solid substance, there are air cells (pores) filled with air, the density of which is incomparably lower than the density of the solid substance. Therefore, two characteristics are determined for building materials: true and average density.

The average density of a material is the density when the calculation takes its total volume, including pores and voids.

The average density of stones is not standardized, but is determined and indicated in the quality certificate.

True density is the density of the substance from which the material is composed. When calculating, the volume of the material is calculated without pores and voids. The true density of each substance is a constant characteristic that cannot be changed, like the average density of a material, without changing its chemical composition or molecular structure. This is the significant difference between true density and average density. To calculate the true density of a material, it must be obtained in an absolutely dense state (without pores).

IT DIRECTLY DEPENDS ON THE CHARACTERISTICS AND PROPERTIES OF THE BLOCKS SPHERE THEIR APPLICATIONS By ordering and purchasing blocks from us, you receive comprehensive advice and guaranteed quality confirmed by quality certificates from a certified laboratory.

In conclusion, we would like to add that our products comply with and satisfy the requirements of SNiP 21-01-97* "" Fire safety of buildings and structures "", satisfies the sound insulation indicators in accordance with SNiP 23-03-2003 "" Protection from noise ""

Soundproofing - Standardized indicators of sound insulation of building enclosing structures are determined for each of them depending on their purpose in accordance with SNiP 23-03-2003 “Noise Protection”.

For walls, these figures range from 50 to 62 dB, for partitions - from 41 to 50 dB.

Fire resistance - The fire resistance limit of building structures is established by the time (in minutes) when signs of limiting states occur:

Loss of bearing capacity (R);

Loss of integrity (E);

Loss of thermal insulation capacity (I).

The fire resistance limit of our expanded clay blocks is 180 minutes at a temperature of 1000 °C.
