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

• Airborne noise insulation index PK-160 (52 dB), SKTs 1R-1pg (54 dB) and SKTs 2R-19 (45 dB) meet the highest requirements of SNiP 23-03 "Noise protection";
• PK-160, SKTs 1R-1pg and SKTs 2R-19 are made of concrete of strength M 200, which ensures vandal resistance of partitions and protection from accidental damage;
• The high strength of the partitions allows you to fearlessly attach any hinged 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 pleasantly pleased with the small weight of the stones and the thoughtfulness of the design: the stones are laid down with a void, which prevents the solution from falling through; the vertical seam is made dry (without mortar) and has a groove-ridge connection system.

Interroom PK-160

3. INSTALLATION OF CONCRETE INTERIOR PARTITIONS

EMPTY 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 walls is a multiple of the whole and / or half-stone. The stone can be cut to the required dimensions, provided that the ribs of rigidity are preserved. The calculation of the maximum wall height is carried out in accordance with paragraphs. 6.16 - 6.20 SNiP II-22-81.

Regulatory requirements for airborne sound insulation index (Rw) are achieved with the correct performance of the following work:

Stones joining (p.- 3.3-3.14, p. 8-10)

Adjacency contours (p. - 3.18, p. 13)

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

Installation of sockets (p. -3.20, p. 14-15)

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

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

- & nbsp– & nbsp–

TECHNOLOGICAL CARD FOR INSTALLATION OF PARTITIONS

The stones are joined by combining the groove and ridge from top to bottom. The ingress of the mortar mixture into the vertical seam is unacceptable.

- & nbsp– & nbsp–

3.4 The stones are laid in a spaced way by joining the groove and the ridge of the stones to be laid with the voids down. The laying of stones with voids upwards with filling the voids with a mortar mixture is allowed to be used only in places previously indicated in the project, for fastening the dowel structure.

3.5 The distance in the order between the vertical seams should be at least 90 mm and not more than 310 mm. - for SKTs 2R-19. Distances in the order between vertical seams of one row for additional stones are not standardized. The strength of the masonry is achieved by following the ordering rules. In the corners and places of intersection of walls with each other, stones must be laid so that they alternately overlap the joints of the lower rows, providing a dressing.

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

3.7 The masonry of the floor partitions is divided into 3 tiers, the height of each of which is no more than 1.2 m. The masonry of the walls of the first tier is carried out from the floor overlap, the second and third tiers - from the scaffold.

3.8 The thickness of the 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 The vertical connection of whole stones is carried out without mortar, by joining the groove and the ridge of the stones to be laid with grouting on both sides with a mortar mixture.

- & nbsp– & nbsp–

TECHNOLOGICAL CARD FOR INSTALLATION OF PARTITIONS

3.10 The vertical joint is made with mortar only in the case of joining:

Two sawn stones.

One sawn and one whole stone.

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

3.11 Nodes of abutment of partitions to the main frame of the building are performed according to the working drawings of the project. The vertical seam in the places where the masonry adjoins the walls or columns is filled with masonry mortar up to 30 mm thick.

In the absence of design solutions, the stones are fixed rigidly to the 3.12 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 Fastening of partitions to walls should be carried out evenly in height in at least four places for each abutment.

3.14 If necessary, the fastening of partitions to the ceilings is carried out through a mortgage (galvanized punched tape), which is inserted into the groove to the entire height of the whole stone and clamped with the ridge of the next whole stone with a mandatory mortar vertical seam. The fastening step 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 each fourth row of masonry. In this case, the reinforcement is laid in such a way that when laying the upper row of stones, the rods fall into special grooves on the lower surface of the stone.

- & nbsp– & nbsp–

TECHNOLOGICAL CARD FOR INSTALLATION OF PARTITIONS

3.16 When reinforcement for anchoring to walls and longitudinal reinforcement intersects in one row, they must be overlapped by at least 100 mm.

3.17 For the door lintel:

Operation PK-1200dp is performed only on whole stones of at least 100 mm. (Figure 9). Installation of PK-1200dp is carried out with a recess (groove) down.

TECHNOLOGICAL CARD FOR INSTALLATION OF PARTITIONS

with a width of up to 1600mm, it is recommended to use two PK-1200dp stones clamped in the masonry as a console with an operation of at least 400 mm with a lower reinforcement with metal reinforcement of class A-III with the introduction of the end parts of the reinforcing bar by at least 250 mm into the masonry structure. ( Fig. 10.11).

Operation PK-1200dp is performed only on whole stones.

Installation of PK-1200dp is carried out with a recess (groove) down.

3.18 To prevent the occurrence of stresses in the masonry and ensure the sound-insulating properties of the partition, a horizontal expansion joint with a thickness of 30 mm is provided. The gap formed after the completion of the work and the drying of the masonry, between the last row of stones and the above floor slab, is filled with an elastic material with further grouting. For example, with a polyethylene foam bundle 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:

Slitting on the wall. Performed by an electric circular saw. A round recess for a rosette is drilled with a crown on concrete of the corresponding diameter.

- & nbsp– & nbsp–

TECHNOLOGICAL CARD FOR INSTALLATION OF PARTITIONS

No gouging. The construction of the stone allows you to lay utility networks (preparation) through the voids during masonry.

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

Chipping with a percussion tool (perforator, chipper) is not allowed.

With a large number of vertical strobes, it is imperative to fasten the partition structure to the base wall and ceiling, ensuring the stability of the masonry.

To restore the soundproof properties of the stone, it is necessary to wipe the strobe with a mortar mixture of at least M100 to a thickness not less than the thickness of the stone wall.

3.20 The output of sockets, switches, etc. is not allowed. on both sides of one stone at the same time (opposite each other), at the request of SNiP 23-03-2003 "Noise protection". For such holes, use adjacent stones.

Block marking and designation

The conventional designation of wall stones according to GOST 6133-99 should consist of an abbreviated designation of a stone - K, its scope and purpose (C - for laying walls or P - for partitions; L - front or P - ordinary), the type of stone from the point of view of its use in masonry (PR - ordinal, UG - angular, 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 symbolic designation of a wall stone ordinary ordinal hollow with a length of 390 mm, a grade for strength 100, grade for frost resistance F75 and an average density of 1400 kg / m3: KSR-PR-PS-39-100-F75-1400

Analysis of the properties of wall blocks:

Thermal conductivity - the property to transfer heat from warmer areas to colder ones. Quantitatively, thermal conductivity is determined by the coefficient of thermal conductivity (λ), which expresses the amount of heat passing through a sample of material with a thickness of 1 m and an area of \u200b\u200b1 square meter at a temperature difference on opposite surfaces of 1 ° C per hour. The value of thermal conductivity is influenced by the density of the material, the type, size and location of the 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 the enclosing structures of buildings - walls, ceilings, floors, roofs. Lightweight and porous materials have little heat conduction. The higher the density of the material, the higher its thermal conductivity.

Knowing the coefficient of thermal conductivity (λ) of the material, it is not difficult to calculate the thickness of the walls of your object.

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

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

In the marking of the wall block, according to GOST 6133-99, the strength grade M must be indicated, which shows what maximum pressure (kg / cm2) it can withstand.

Example: The wall block has a strength grade M50. This means that it can withstand a pressure of 50 kg / cm2 or per block: 39cm x 19cm * 50 kg / cm2 \u003d 37050 kg or 37.05 tons.

Frost resistance - the ability of a material in a state saturated with water 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% during freezing. Testing of building materials for frost resistance consists in cyclic alternating freezing and thawing in a state saturated with water and subsequent determination of the loss of mass and strength by the material. Freezing and subsequent thawing of the sample is one cycle; the cycle time 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 state saturated with water, its strength has decreased by no more than 15-25%, and weight loss has not exceeded 5%.

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

Dear customers, we would like to clarify the following about this parameter, in practice there is often an erroneous understanding of this parameter, that is, many understand this as 1 cycle \u003d 1 year, this is not the case, for example, frost resistance F100 or F35 means that 100 or 35 freezing cycles have been carried out / thawing. According to the norms for blocks and our climatic region, it is enough to have an indicator at the level of 35-50 cycles, and most manufacturers stop their tests at this figure. This does not mean that these blocks will collapse during further tests, and the F100 characteristic is a rather high indicator, it meets the requirements for facing bricks, since the brick is in direct contact with the environment and is not protected from rain and snow in any way.

Density - called the mass of a unit volume of 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, i.e. in their volume, in addition to solid matter, there are air cells (pores) filled with air, the density of which is incomparably lower than the density of solid matter. Therefore, for building materials, two characteristics are determined: true and average density.

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

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

The true density is the density of the substance of 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 essential difference between the true density and the average. To calculate the true density of a material, it must be obtained in an absolutely dense state (without pores).
