Tongue-and-groove plates

Weight of tongue-and-groove plate

When erecting self-supporting interior walls, tongue-and-groove slabs can be used. They can be chosen for the construction of offices, apartments, industrial and other structures.

Specifications and weight of gypsum tongue-and-groove plates

The main technical characteristics include the following data:

• Dimensions. The standard version has dimensions of 667x500x80 mm; plates of other sizes can also be found.
• The weight. Overall dimensions and density index affect the weight of gypsum tongue-and-groove plates. A standard plate weighs about 27 kg.
• The density is 1000 kg / m3. A tongue-and-groove gypsum slab, the weight of which depends on this indicator, may have a higher density, which affects the surface hardness.
• The compressive strength is within 4.5 MPa. This indicator characterizes the possibility of using a slab as a load-bearing element of a building.
• Flexural strength 2.2 MPa.
• Fire resistance indicator is not less than 2.5 hours.

Plates are usually packed in packs of 15 pieces. Packages are stacked on pallets.

Weight of tongue-and-groove plate 667 500

On the construction market, you can find various options for the execution of plates. Density, fire resistance, flexural strength and compressive strength will be almost the same. In this case, the weight of the tongue-and-groove plate 667x500x80 is 28 kg. With the same dimensions, but increasing the thickness of the slab to 100 millimeters, the weight will already be 37 kg.

Manufacturers

Today, the production of tongue-and-groove slabs is carried out by dozens of companies. But until recently, this list barely consisted of 2-3 brands. With the growth of competition, the range of products has also increased. Among those brands whose products are worth considering for purchase today, the following can be distinguished.

Knauf. The company with German roots has long gained popularity in the Russian market. In this brand, PGPs are presented in a wide range of standard sizes, are distinguished by the stability of geometric parameters and excellent quality. Knauf produces both moisture resistant and conventional boards, giving preference to gypsum options.

Technology of erection of partitions from tongue-and-groove plates

As a rule, before proceeding directly with the installation, you need to perform the following preparatory work:

• assess the quality and horizontalness of the supporting surface, if necessary, eliminate defects and level the base;
• using a laser level or a plumb line, mark the future partition, taking into account door and window openings;
• at the points of contact of the GWP with the base and the bounding walls, it is necessary to glue a damping cork layer.

Laying the support row

The quality of installation of the entire future partition depends on the accuracy of the installation of the first row, therefore, special attention should be paid to the installation of the support row. Below is the sequence of works for laying the first row:

1. The thorns of the PGPs stacked in the bottom row are removed using a grinder or a hacksaw, after which the plane is processed with a special plane for plaster;
2. The selected adhesive is applied to the surface of the seal. Most often, special gypsum polymer glue is used for the installation of partitions;
3. Using a mounting angle or a curved perforated bracket installed in the grooves, using self-tapping screws and dowels, the block is fixed relative to the base and bounding walls;
4. All subsequent blocks of the first row are mounted in the same way, with the only difference that the panel is fixed with a corner or bracket only to the supporting surface.

Important! Installation of the next block should be carried out only after the glue has set. Otherwise, the integrity of the structure may be violated.

Laying the main part of the partition

Installation must be done with an offset (by analogy with ordinary brickwork).To do this, the slab adjacent to the wall is cut in half and installed in the groove of the previous row. After installation, as with the laying of the first row, it is attached to the bounding wall.

The glue is diluted a little less often than when laying the first row and is applied to the bottom and side edges of the blocks. To reduce moisture absorption, the end surfaces of the slabs can be treated with a deep penetration primer.

Important! After installing each block, it is necessary to control the vertical and horizontal level, as well as the location of the slab relative to the marking

Installation of the last row

After laying the last row, the distance from the upper edge of the block to the ceiling should be from 1 to 3 cm, if necessary, the slab is cut to the required size. After the adhesive has completely dried, the remaining gap is filled with polyurethane foam. After the foam has set, the excess is removed with a sharp knife.

Construction of partitions with a doorway

The technology of laying the first and subsequent rows in the presence of an opening practically does not change. The difference lies in the laying of the tongue-and-groove blocks directly above the opening.

Experience shows that if the width of the opening does not exceed 80 cm, and the distance from the ceiling to the upper part of the opening corresponds to one row, it is allowed to lay the panels directly on the door frame.

If the opening is wider than 80 cm, or there will be several rows of GWP above it, it is necessary to install a load-bearing lintel made of a channel or thick beam. The sequence of work on the device of the doorway is as follows:

1. Upon reaching the upper level of the opening in the slabs, using a hacksaw, grooves with a depth of 100 - 150 mm are cut out. The groove height depends on the lintel thickness;
2. The inner surface of the groove is abundantly lubricated with glue, after which the jumper is installed. Excess glue is removed with a spatula immediately, since after the adhesive has hardened, it will be much more difficult to do this.
3. After the glue has completely dried, the required number of blocks is placed on the lintel.

The outer corners are reinforced with a perforated aluminum corner. For the convenience of fastening, you can use a stapler, after which the corner is putty in such a way that a special protrusion remains visible. The inner corners are reinforced with a fiberglass mesh.

Before finishing finishing work (putty, wallpapering, painting, etc.), the partition is treated with a deep penetration primer.

Installation features

Installation of GWP partitions is performed after the completion of the installation of any supporting or enclosing structures. Work is carried out in dry or normal humidity conditions when the air in the room is heated at least + 5 degrees. When carrying out construction work in winter, a heating connection is required.

First you need to remove all dirt and construction dust from the base walls, as well as the surface of the ceiling and floor. After that, you need to mark the location of the future partition on the floor, and then, using a plumb line, carefully transfer this markup to the walls and ceiling, fix the areas for window and door openings. If the base is curved and has noticeable irregularities, then a leveling screed should be performed so that the horizontal surface becomes level.

Gypsum boards are laid using assembly glue, the most effective is "GIFAS Gypsum Glue" or "GIFAS Gypsum Putty". When working with moisture-resistant compounds, hydrophobic compounds give the best adhesion. In order to increase the sound insulation characteristics of tongue-and-groove slabs when fixing them to the enclosing structures, you can use an elastic gasket, most often it is a cork with a density of 50 kg / m³ or bitumen felt with a density of 250-300 kg / m³, as an alternative, you can fix low-density fiberboard.

Depending on the specifics of the production, gypsum boards can be placed either with a puzzle down or with a puzzle up. Experts recommend using the puzzle upwards, because then the glue will be better redistributed in the slab space. To do this, for all GWPs located in the first row, you need to remove the comb. The plates are fixed apart, due to this, the greatest rigidity of the structure is ensured. The slabs of the very last row should have slightly beveled edges in the area of ​​abutment to the floor. The space between the ceiling and the slab of the very last row (approximately 2-3 cm) is filled with gypsum glue throughout the entire volume.

Openings are inserted into the partitions for installing windows or doors in them. If the width of the opening is not more than 800 mm and only one row of panels is located on it, then there is no need to install a lintel beam, in this case, you can put a regular door frame. If the width of the opening exceeds 800 mm, then the installation of the lintel beam is necessary, it will relieve the load from the upper rows of blocks. The embedment size is approximately 500 mm on each side. Door frames are fixed with special dowels or screws. The vertical joints of the slabs located next to the openings must be at least 20 cm apart.

In the corners, as well as in the areas of intersection of partitions with each other, GWP should be laid in such a way that they in turn close the joints

At the same time, it is important to try not to allow vertical joints to turn out to be through. The upper corners are additionally fixed with a perforated metal profile

Reinforcement tape is used to process the inner corners. The internal joints of partitions made of hydro-resistant PHB must additionally be covered with a waterproofing tape, it plays the role of a sealant.

After the putty or glue dries, the surface of the walls is carefully sanded. The gypsum polymer partition is ready - all that remains is to complete the finishing, usually the GWP is painted with interior paint or pasted over with wallpaper. We hope our recommendations will help you make the right choice of tongue-and-groove gypsum board and perform all installation work on your own.

Walls: foam concrete

What is drywall? This is a building material, which is a sheet consisting of two layers of construction paper, and inside it is gypsum with a filler. It can be ordinary, moisture resistant and fire resistant.

Environmentally friendly.To work with drywall, you also need profiles, self-tapping screws, dowel-nails, a serpyanka for seams. All this is about 60 - 70% of the price of the sheet price. You may need sound insulation - Izover, TeploKnauf, Ursa, etc. Wall = 6 m * 3m * 0.2m = 3.6 m / cc. Hence 3.6 / 0.036 = 100 pcs.

Block cost: 100 pcs * 160 = 16000 rubles. The glue will take about 4-5 bags. Hence 5 * 200 rubles = 1000 rubles. Total 17,000 rubles Now we need to find out the square of the wall.

To do this, we multiply the length of the wall by the height: 6 m * 3 m = 18 m / sq. Since the wall is double, then 18 * 2 = 36 m / sq. To work with foam concrete, you will need glue.

For masonry, it is better to take glue specifically for foam concrete, and not ordinary tile glue, so that cold bridges do not arise (provided that the work is not carried out indoors). The price of a bag is on average 200 rubles / 25 kg. Glue consumption 15 kg per 1 m3 / cu.

Advantages and disadvantages

Builders love tongue-and-groove gypsum slabs for the standard of parameters, compliance with GOST, as well as the convenience of working with them. The main advantage of tongue-and-groove slabs is their affordable cost - the prices for this material are much more attractive than for any other wall materials, such as gas silicate blocks or sand concrete. In addition, the boards are easy and simple to install by gluing, which ensures a high speed of construction work.

Another advantage of gypsum board is the absence of any wet processes.Installation of GWP does not require plastering work, since initially this material is produced with a leveled smooth surface. Thanks to this, immediately after the installation of the partitions, you can paint them or paste over with wallpaper. The use of these blocks greatly increases the productivity of work and significantly reduces the time for the construction of any objects.

There are no drawbacks as such for the GWP. However, it should be borne in mind that after purchase, they must certainly undergo acclimatization indoors - before starting work, they must be kept at heating at least +5 degrees for 4–6 hours. In addition, load constraints should be considered. Some types of GWP cannot be used for the construction of partitions on which it is planned to mount heavy furniture blocks or other bulky structures.

Types and sizes

According to the interstate requirements of the standard, each tongue-and-groove plate must have clear dimensions:

• 667 × 500 mm;
• 660x500 mm;
• 900 × 300 mm.

The thickness of the blocks ranges from 80 to 100 mm. The most common dimensions are 667x500x80 mm. As for the density, this indicator depends entirely on the materials used in the manufacture. Thus, it turns out that the density level for gypsum blocks is 1050–1300 kg / m³, and for silicate blocks the minimum value is 1870 kg / m³.

With the stated requirements of the state standard, tongue-and-groove plates differ in several parameters. And first of all it is the composition.

• Gypsum boards are molded. They contain gypsum and plasticizer. According to the technical specifications, the level of thermal insulation of gypsum blocks is very high. An 8 cm slab is equivalent to a wall covered with a 4 cm thick layer of concrete.
• Silicate slabs are made from quartz sand, lime and water. Their technical characteristics are similar in almost all respects to gypsum blocks.

To date, the blocks produced by PGP are divided according to the type of fasteners. The groove / tongue can be rectangular or trapezoidal. There is no difference between the strength of the fasteners. The question of the choice assumes the convenience of installation for the master himself.

On the construction market, you can find several types of tongue-and-groove slabs.

• Standard. They are used in rooms with low humidity levels. But at the same time, the height of the walls of the room should not be more than 4.2 m.
• Hydrophobized. A more understandable name is moisture resistant. These boards contain special water-repellent additives. You can determine that these are hydrophobized slabs by their greenish tint.
• Shungite. These plates are supposed to be used in rooms where a lot of devices with electromagnetic radiation are installed. These slabs contain coal, which is why they have a black color.

Also, tongue-and-groove blocks are produced in the form of hollow and solid structures. Hollow core slabs are used to create partitions in a home environment.Solid blocks - for wall mounting in industrial and public buildings.

Installation features

There are certain requirements when working with
tongue-and-groove structures and should not be forgotten.

1. Work
   with PGP plates is needed before finishing work and the manufacture of a floor
   cover.
2. Air
   in the room planned for the construction of the partition should not be lower than five
   degrees Celcius.
3. Front
   how to start the installation of blocks, it is necessary to initially treat them with a primer,
   to improve the performance of the product.

As for the installation works themselves, they provide
certain milestone activities, which consist of:

• preparatory work;
• main;
• final.

At the preparation stage, it is necessary to clean the surfaces from
dirt and dust, and if necessary, you can make a screed on the floor. After drying
marking of the future partition is done

It is important to initially indicate in the markup where
there will be an entrance and an approximate place of passage of communications and wiring

@PGP

The main stage of work involves gluing the gasket
along the entire perimeter of the proposed partition. The gasket is glued to the ceiling,
wall and floor. Only after the glue has completely dried can you begin to install
blocks for glue.

Shrinkage of the slab is done with a rubber mallet to
the structure did not collapse from the impact. So that the plates lay down correctly and evenly when
building level assistance, measurements and exposures are made. Blocky
the structure must be flat both vertically and horizontally. If during
work, it is necessary to cut off part of the product for this you will need an ordinary manual
a hacksaw that easily copes with the task.

How much does the tongue-and-groove plate weigh?

The question is good and urgent for those wishing to carry out a global renovation in an apartment. Construction work can be carried out using a variety of products such as bricks, plasterboards, concrete blocks, and more. Each has certain pros and cons, big and small. The main point is the load resulting from the construction of wall structures. A problem arises: what material to choose for work? PGP, friends, only PGP!

What it is? It's that simple! Along with classic building materials, the consumer is offered a unique product designed specifically for the construction of unloaded walls and partitions. And his name is - full-bodied PGP Volma tongue-and-groove plate. To find out how much the tongue-and-groove plate weighs, our article will help.

The secret of popularity

This is what GWP looks like

Load-bearing, capital walls make up the "skeleton" of an apartment - you cannot touch them, but you can "play around" with partitions and partitions.

One of the important points is the need to calculate the load that the new wall will have on the load-bearing floor slab.

In all respects, a tongue-and-groove plate is suitable for such work.

There are two main brands on the construction market - imported Knauf and domestic Volma.

According to their technical characteristics, they are identical building materials, so each one will not be considered separately.Such slabs differ only in price.

According to experts, the Knauf corpulent tongue-and-groove slab occupies a leading place in the field of installation of partitions. And there are good reasons for this.

5 reasons for the PPP

Manufacturers produce products that meet all technical and construction requirements. Possesses a number of remarkable qualities.

• High-precision geometric dimensions. The standard size of the slabs is 0.667x0.5 m, with a thickness of 0.08 and 0.1 m. And this is all observed down to the millimeter. This precision guarantees a high quality installation and overall reliability of the entire structure.
• Ease of processing. You do not need a "grinder", an ordinary hacksaw for wood is enough and not a single plate will resist your onslaught.Simple and effective! There is practically no waste. Another plus in favor of tongue-and-groove plates.
• Economical installation. Exact size matching allows the use of adhesive mixtures, while the seam thickness is up to 10 mm. You can save a lot on the installation solution and at the same time reduce the total weight of the structure.

When installing brickwork, the mortar accounts for at least 20% of the total volume of the structure.

• You will definitely find your own in a wide range of PPEs!

  The main lineup. Modern tongue-and-groove slabs have three main modifications: solid or monolithic; the groove-ribbed slab PGP Volma is hollow - there are voids in the structure that reduce the total weight; moisture resistant - used for installation in high humidity conditions (bathroom).

• And the most important thing is its low specific weight. A standard solid board with a thickness of 80 mm weighs only 28 kg, and 100 mm - 32 kg. Compared with traditional bricks, the area of ​​the wall from the tongue-and-groove slab will be approximately 2-2.5 lighter. But that is not all. Technologists have developed a special type - a lightweight hollow model. The presence of voids in the structure made it possible to reduce the weight to 22 kg. The result is a win in favor of the GWP. Partitions of the same area of ​​tongue-and-groove slabs, in comparison with clay brick, are 3 times lighter. A very important indicator that plays a key role in the choice of material.

It is also worth noting that products from Volma and Knauf have the ability to maintain and regulate the level of humidity, are distinguished by a sufficient degree of sound insulation, and are not subject to changes in linear dimensions during temperature fluctuations. Ideal for finishing work.

We will answer all your questions about GWP!

Silicate or gypsum?

If we compare the sound insulation characteristics of gypsum blocks and silicate blocks, the latter, with equal parameters, conduct sounds worse (40-43 dB for gypsum blocks and 48-52 dB for silicate ones). So we choose silicate for better sound insulation.

Dimensions according to GOST and TU

But silicate blocks of the same size have more weight and higher thermal conductivity (they conduct heat better). The key in the choice is weight, since sound and thermal insulation can be improved with the help of additional layers of special materials, but there is no way to reduce the weight of the partition. And if its mass is critical for overlap, nothing good can be expected.

What it is?

Tongue slabs or, as they are called abbreviatedly, GWP is a wall material used in the installation of load-bearing partitions indoors. A distinctive feature of these slabs is the presence of protruding and falling parts, which serve as reliable fixing elements for partition plates.

In construction, special attention is paid to tongue-and-groove slabs, since this material has a number of significant advantages:

• quick installation;
• the minimum amount of consumable glue for fixing the plates;
• the surface of the GWP does not require the application of plaster;
• environmental friendliness;
• fire resistance;
• high level of thermal insulation;
• excellent sound insulation.

But despite the advantages presented, the GWP material has some disadvantages:

• a high level of hygroscopicity limits the use of GWP in rooms with high humidity;
• partitions installed by GWP have restrictions on the weight of the attached equipment;
• with building settlement and even minimal seismicity, there is a likelihood of cracks and deformation of blocks.

However, modern manufacturers, realizing that partitions are necessary in rooms with high levels of humidity, have developed waterproof tongue-and-groove blocks.
