Cranes, lifting mechanisms and auxiliary devices used during installation work must meet the established requirements of the inspection rules of the Gosgortekhnadzor. Before starting installation work and periodically during work, all used rigging and installation devices (slings, traverses, etc.) must be subject to survey and inspection in accordance with the Rules for the Construction and Safe Operation of Cranes. Workers at least 18 years of age who have undergone a medical examination and safety training and have the appropriate certificates are allowed to perform installation work. Fitters, welders and other workers involved in the installation of the main structures of the house must be provided with tested safety belts. On the site (grip) where installation work is being carried out, other work and the presence of unauthorized persons are not allowed. During breaks in work, it is not allowed to leave the raised structural elements on weight. Unslinging parts during unloading or loading is allowed only after checking their stability. On ceilings, scaffolding and scaffolding, only assembly, installation and fitting are allowed. Work on the manufacture of missing parts on scaffolding and scaffolding is not allowed. Before performing installation work, it is necessary to establish the procedure for the exchange of conditional signals between the person in charge of the installation and the driver (minder). All signals are given by only one person (the foreman of the installation team, the team leader, the rigger-slinger), except for the “Stop” signal, which can be given by any employee who has noticed a clear danger. Installation of structures of each subsequent tier (section) of a building or structure should be carried out only after all elements of the previous tier (section) are securely fastened in accordance with the project. Hinged metal ladders with a height of more than 5 m must be fenced with metal arcs with vertical ties and securely attached to the structure or equipment. Climbing workers on hinged ladders to a height of more than 10 m is allowed if the stairs are equipped with rest areas at least every 10 m in height. 7. Technical and economic indicators The composition of the link for the installation of partitions from tongue-and-groove plates is given in the table Bricklayer

Partitions made of tongue-and-groove slabs (hereinafter referred to as GWP) are a prefabricated large-block structure. Blocks are made by molding. They are distinguished by increased accuracy - the deviation of the working surfaces is not more than 1.5 mm from the specified one. Depending on the raw materials used, they are divided into two types:

• silicate. Produced by silicification quartz sand and lime in an autoclave under the influence high temperatures. This technology makes it possible to obtain a durable, moisture-resistant, non-combustible material.
• Gypsum. The main raw material is gypsum. To achieve the desired characteristics, plasticizers and other chemical additives are introduced into it. This makes it possible to obtain the necessary strength and moisture resistance. Depending on this product are divided into types. The environmental safety of raw materials makes it possible to use it without restrictions even in children's rooms.

The sizes of tongue-and-groove blocks for partitions from different manufacturers may vary. We list the most common options:

• 667x500;
• 250x500;
• 300x900;
• 599x199.

Partition plates of all standard sizes are produced with a thickness of 70, 80 and 100 mm. Depending on the design, they are divided into two types:

• Full bodied. They are solid monolithic elements. They are used if you need to provide high strength, for example, hang heavy shelves or cabinets.
• Hollow. They have round perforations. This makes them lighter and therefore easier to install. Due to the voids, the products have increased sound insulation. They can also be used as conduits for electrical wiring.

Depending on the purpose of the premises, inner wall can be made single or double. If you place a mineral wool insulation between the gypsum panels, you can achieve one hundred percent sound insulation between adjacent apartments.

Pros and cons of using tongue-and-groove blocks for partitions

Advantages:

• Availability. The use of the material is economically justified. Prefabricated gypsum structures are lighter than ceramic bricks, stronger than drywall and gas silicate foam. At the same time, their cost is lower by 10-30%.
• Safety. Raw materials for the production of GWP do not contain impurities harmful to health. The products themselves are highly fire resistant.
• Soundproofing. Subject to the installation technology, the wall prevents the penetration of loud sounds into adjacent rooms.
• Ease of installation. Thanks to the connection of individual elements according to the tongue-and-groove principle, even a person without experience in carrying out such work can cope with the construction of the PGP. The main thing is to correctly mark up and constantly control the straightness of the rule.
• Ease. The material is almost twice as light as brick, which reduces the load on the interfloor ceiling. At the same time, you get thinner interior partitions, which gives additional usable space.

Flaws:

• Hygroscopicity. Standard tongue-and-groove slabs absorb moisture well, and during the drying process they can be deformed. Therefore, it is important to mount them after the completion of all wet processes in the room.
• Fragility. At high loads, the material bursts at the point of greatest stress. Therefore, before the device of the wall along wooden floor, it needs to be well reinforced. In new buildings, which can shrink, it is imperative to use damping tapes.
• Foundation requirement. The large-block structure does not allow the adjoining surfaces to be leveled during the construction of walls, as can be done, for example, with a brick. This means that you first have to carefully align all the planes.

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

The construction of the GWP is started after the completion plastering works, laying electrical and plumbing communications, but before the installation of subfloors. Humidity should not exceed 60%, and the air temperature should be above 5 degrees.

Foundation preparation

All adjoining surfaces must be flat, strictly horizontal or vertical. If the planes do not correspond to the level, we level them with concrete or cement-sand mortar. The hardened base is dedusted and primed.

We apply markings on the floor in accordance with the project and mark the location doorways. With the help of a level or a laser line builder, we transfer the lines to the walls and ceiling.

You can quickly and perfectly evenly draw marking lines with a construction chopping cord. It's better to do it together.

To increase sound insulation, we glue a cork elastic gasket with a mounting solution to all surfaces adjacent to the GWP. We press it with a building level, controlling the correspondence of the vertical and horizontal.

For novice craftsmen, the contour of the cork gasket helps to achieve the perfect geometry of the walls. It serves as a guide when checking planes with a rule.

Partition wall fastening

Regular fasteners for PGP are brackets C3 (with a thickness of 1 cm) and C2 (with a thickness of 0.8 cm). They are screwed with screws to the walls, ceiling and wooden floor at the junction. On concrete floor the necessary strength creates an adhesive solution.

But more often for fastening they use mounting equal-shelf corners 100x100 mm or drywall hangers.

With a ceiling height of 2800 mm, it is enough to fix the vertical in three places. Horizontally, fasteners are installed every 600 - 1000 mm.

Gypsum panels remain stable when erecting straight structures up to 3600 mm high and 6000 mm long. The distance is measured between the corners of the intersection.

Corner plates must be fastened to each other with perforated tape or a suspension for plasterboard.

The construction of the first row of tongue-and-groove blocks

After delivery of the material to the object, it must be laid down for a day. During this time, the temperature and humidity levels out.

Gypsum panels can be laid with the groove up or down. In the first variant, the mortar mixture is more evenly distributed over the plane of contact between the elements. Therefore, before arranging the first row with a hacksaw with a large tooth, we cut off the comb from the bottom side. Installation is carried out in the following sequence:

1. Knead a small portion of the adhesive solution. Particular attention should be paid to the time of its viability. Usually it is 30-60 minutes.
2. We apply glue according to the markings on the floor and wall.
3. We install the first tongue-and-groove block. We apply the level from above and, tapping with a rubber mallet, align the horizontal. Each time, with a small level or a long marking rule, we control the vertical.
4. Immediately remove the excess mortar mixture. When hardened, it will spoil the finish coating.
5. If necessary, we fix the plate to the enclosing structures.

We repeat the steps for the remaining elements of the first row. We pay special attention to the conformity of dimensions, straightness and verticality. For control, we use the level, roulette and the rule.

The construction of subsequent rows

General principles installation remain the same, but there are some peculiarities. Do not allow the vertical seams of adjacent rows to coincide. It is necessary to perform them with a run of at least 1 cm. To do this, cut the block in half. We install one part of it on the whole panel, which started the first row. The second one is used as a supplement.

It is important to observe the dressing in the corners and intersections of the walls. If the block has a groove and a ridge along its entire length, we cut them at the corner joints. Otherwise, the comb will not go into the groove.

Due to the low viability of the adhesive solution, we first cut the parts and adjust their size to dry. Only after that we fill the groove with glue, and install the element. Be sure to remove the squeezed out excess mortar mixture.

Formation of doorways

When arranging an opening up to 900 mm wide, you can do without additional load-bearing structures. At the same time, it is important to arrange it so that there are no freely hanging plates above the door. Therefore, for such places, we first draw a laying scheme on paper. We start with a row above the doorway. We place the vertical seam in the middle of the span. Only then do we paint the rest of the elements, adhering to the rule of spacing the seams.

At the stage of erecting the wall, we fasten a temporary jumper made of wood or a drywall profile (supports are allowed). After the adhesive mixture has hardened, remove the temporary mounting parts.

Above openings wider than 900 mm, we must install a jumper: wooden block, metal corner or channel. The support should be in the range of 100-150 mm. The top of the door does not have to be aligned with the horizontal mounting joint. It is enough to cut the groove for the jumper at the right level.

It is important to think in advance about the finishing of embedded elements. Metal parts are covered with paint in three layers. We impregnate the wooden ones with an antiseptic, and for better adhesion we sheathe the front parts with strips of drywall.

The construction of the last row of tongue-and-groove blocks

It is inconvenient to finish laying with narrow trimmings. Therefore, for ease of installation, it is allowed to install the plates of the upper row vertically. The tongue-and-groove system does not allow joining the elements right up to the ceiling. A clearance is required for their installation. To facilitate the sealing of the seam, we cut the upper plane diagonally. On the side closest to the installer, a gap of 2-3 millimeters is sufficient. The cutting line of the far part should be at a distance of 2-5 cm from the overlap.

If in the future it is planned to install a stretch ceiling, we foam the gap mounting foam. When it is important to make a smooth abutment, we fill the hole gypsum plaster. We do this in several stages, observing the layer thickness recommended by the manufacturer.

It is important to fix the GWP to the ceiling with mounting brackets or corners. Otherwise, the top edge may become loose.

Electrical installation

If necessary, we lay wiring in the tongue-and-groove partitions, install sockets and switches. IN hollow blocks using internal channels. If you know the places for laying communications in advance, you can pre-drill the holes in the ridge to the desired diameter. This will make wiring easier.

In full-bodied panels, we cut the strobes with a manual or mechanical strobe cutter. Holes for socket boxes are drilled with crowns on wood.

It is not allowed to use impact tools: hammer drill or impact drill.

Prepared channels are dedusted and primed. After installing the cables, we seal the strobes with a gypsum adhesive solution.

For clarity, and to simplify the installation of partitions from tongue-and-groove plates with our own hands, we provide a video instruction.

This video shows the process of erecting a partition from hollow Volma tongue-and-groove slabs.

(GWP) is one of the most optimal building materials for creating walls and partitions.

GWP is a gypsum block with a groove and a ridge along its ends, thanks to which they are assembled like a Lego constructor. Using this material, you can easily build a partition up to 6m long and up to 3.6m high.

The tongue-and-groove comb can be used in both dry and wet rooms. For the installation of partitions in rooms with high humidity, special moisture-resistant tongue-and-groove plates are made.

Tools and materials for the installation of a partition wall made of HGP

To mount a partition from tongue-and-groove plates, you will need the following materials and tools:

• GWP conventional or moisture resistant
• primer
• mounting adhesive
• gypsum putty
• mounting brackets (straight hangers can be used)
• dowel nails and screws
• spatulas: wide, for external and internal corners
• polyurethane foam
• level
• mallet

You can buy everything necessary for the installation of partitions made of PGP from our company.

Stages of installation of a partition from tongue-and-groove plates

1. Ground preparation

One of the most important conditions for creating a HWP partition is a reliable and stable base. If the base has strong irregularities, it is necessary to perform a leveling layer using a self-leveling floor.

Before starting the installation, clean the floor from dust and dirt. After that, you can proceed to the installation of the partition.

2. Mounting the partition

To increase the adhesion of materials, it is necessary to process all surfaces that will be adjacent to the future partition primer. After the primer dries, mark and prepare the mixture - can be used any gypsum mounting mix.

To improve sound insulation and prevent other negative consequences, it is better to fix the partition to the base through an elastic porous material, such as cork. This step is advisory.

Tongue-and-groove plates are mounted rows. GWP first row mounted from the wall placement on a layer of mounting mixture. The plate can be installed with the groove up or down. To obtain a high-quality design, it is necessary to check using the level of the vertical and horizontal of the future partition.

Before installing the next slab, apply a layer of adhesive to the already installed tongue-and-groove slab and base. After installing the second and subsequent plates, trim them with a mallet to obtain an even structure.

As a rule, to complete the partition it is necessary to use a non-whole GWP slab. There is nothing to worry about, because thanks to the voids, the material is very easily sawn with a hacksaw.

When laying the second and subsequent rows, it is necessary to observe the vertical joints at least 10 cm This makes the structure more durable.

Constantly control the width of the horizontal and vertical joints to avoid additional leveling steps when finishing the pgp partition, it should be minimal.

Plates necessary fasten to walls and bases: they are performed using mounting corners, dowel nails and self-tapping screws.

The last row must be mounted with a gap not less than 1.5 cm from the floor slab, the remaining gap is filled with mounting foam, after stripping the excess, it is necessary to putty the seam with gypsum putty.

3.Finishing the GWP partition

First of all, it is necessary to protect the outer corners of the resulting partition from mechanical damage; for this, corner perforated profile 31*31. Internal corners are reinforced with reinforcing tape.

A leveling layer of gypsum putty must be applied to all corners.

For laying electrical wires or electrical installation products, structural cavities can be used, which must be further expanded with a drill with a crown. With the same tool, it is necessary to prepare external holes for wiring accessories and wiring output.

Before application decorative coating: wallpaper or paint, it is necessary to clean the seams and process them and all irregularities with gypsum putty and prime the surface.

The video also reflects the moments of soundproofing partitions and installation attachments: shelves, plumbing.

Advantages of tongue-and-groove plates:

• ease of assembly
• simplicity of openings
• minimum finishing
• does not require plastering
• low price
• high fire resistance

PGP partitions are used for redevelopment of premises or for delimiting apartments in new buildings. They are distinguished by a smooth surface, ease of installation and budget cost. The blocks are connected using a tongue-and-groove system, the seams on the finished structure are minimal. This makes it possible not to putty, but immediately cover the wall with a primer and decorate it.

Tongue-and-groove slabs for partitions are rectangular elements with longitudinal grooves and protrusions (ridges) at the joints, necessary for a strong and seamless bond. Their standard sizes- 667x500x80 mm, the thickness can be 100 mm.

There are tongue-and-groove-type slabs for partitions of large sizes, floor-to-ceiling high.

Their installation is very fast, but you can’t cope with it on your own - due to heavy weight building elements are assembled by a whole team.

Types of tongue-and-groove blocks for interior partitions depending on the material of manufacture:

View	Preparation method	Positive traits
Gypsum boards	From gypsum with plasticizing additives. Gypsum blocks for partitions are divided into moisture resistant (green) and those whose moisture transmission capacity is high.	Approved for installation in children's rooms. Another plus of gypsum blocks is ease of processing. Gypsum blocks are sawn at any angle - gypsum elements can be used to create structures of various shapes and configurations.
silicate blocks	From quicklime and water with the addition of quartz sand using an autoclave.	They have significant soundproofing qualities. Resistant, compared with gypsum, to the action of moisture, have greater strength and durability.

PGP-partitions can be corpulent and hollow. The latter weigh less (22 kg compared to 28 for monolithic ones), but do not withstand the suspension of massive household items.

Advantages of GWP partitions

The general advantages of a partition made of gypsum or silicone tongue-and-groove plates are:

The use of hollow slabs reduces the load on the supporting base.

The main advantage of such building elements: the installation of tongue-and-groove partitions is not difficult. Finished construction does not require special finishing works. It is not necessary to plaster the wall, it is enough to cover with a primer and decorate.

Installation of partitions from PGP

The installation of partition elements made of gypsum or silicate in an apartment begins after the construction of the load-bearing parts, but before laying the subfloor and starting the painting and plastering work.

Installation of a partition from standard-sized tongue-and-groove plates takes only two to three days. This is due to the convenient tongue-and-groove system and the absence of the need for additional reinforcement.

When docking, any deviations along the planes are excluded, which allows you to assemble a smooth wall in a short time without even a millimeter error.

If you need to hide communications, special strobes are made in full-bodied blocks. In hollow wires and pipes can be laid in the inner cavity. If the construction of partitions from PGP does not involve gating, the double wall method is used. But they "eat up" twice as much space.

Materials and tools

To build a partition from tongue-and-groove slabs, you will need the following set of tools:

• roulette;
• electric drill;
• mallet;
• construction level;
• putty knife;
• hand saw;
• ruler, pencil;
• screwdriver;
• glue mixer.

From the materials you will need the blocks themselves, a sealant made of cork or felt, an edge tape, a rope, glue, a primer. Fasteners are also needed: screws, dowel-nails, fixing brackets - straight hangers or corners.

Preparatory work

The construction of a partition created from tongue-and-groove blocks requires some preparation. First of all, you need to check the correspondence of the floor and ceiling horizontal levels, and make sure that the tongue-and-groove slabs closely adjoin them: grind outstanding irregularities, fill cracked areas and recesses with a solution of cement and sand.

The blocks are brought into the room no later than 24 hours before installation, so that the material "adapts", that is, it has the necessary humidity and temperature.

Gypsum-based acrylic adhesive is used to build the wall.

But it is very expensive, so many people replace it with ordinary tile adhesive or a 1: 3 cement-sand mortar with the addition of polyvinyl acetate adhesive. If everything is thoroughly mixed, a rather plastic and finely dispersed mixture comes out, easily applied with a spatula. Laying with a mortar is easier, since its setting time is longer than that of gypsum glue.

Before the construction of interior partitions, all areas of surfaces in contact with them are primed and marked according to a previously created drawing.

Laying tongue-and-groove blocks

It is not difficult to assemble a partition from tongue-and-groove plates with your own hands. The main thing is not to violate the technology during the construction of bulkheads from GWP.

Installation guide for partitions made of tongue-and-groove plates - step by step instructions:

If an opening for a door is required in the design of a false wall, it is necessary to fix the blocks located on top. When mounting one row of blocks over an opening up to 0.8 m wide, we can mount them on a door frame or a non-permanent wooden lintel.

If the width is more than 0.8 m or it is necessary to lay several rows, it will be necessary to install a jumper for tongue-and-groove plates made of wooden blocks or a metal channel.

It is mounted on glue in specially made cuts about 5 cm deep in the corner blocks. After the solution has dried, the upper rows of plates are installed.

After completion of work, the tongue-and-groove partitions must be primed. Especially if tongue-and-groove gypsum boards were used. The primer ensures the adhesion of the decorative layer and will avoid the appearance of surface defects.

For decoration, any type of wallpaper and coloring are suitable. Kitchen and bathroom needs to be redone tiles or plastic panels. For the living room, nursery, bedroom, wallpaper or decorative plaster is more often chosen.

Interior wall partitions, in most cases, are not load-bearing structures in the house. They must have sufficient strength and good soundproofing properties. The design of the partition should easily withstand intra-house communications and hanging furniture.

In this article we will talk about tongue-and-groove gypsum (gypsum) slabs (GWP). This material is used to create interroom and interroom partitions. With a competent approach to the construction, partitions made of tongue-and-groove gypsum boards (GWP) will meet the requirements listed above. But you need to focus on the fact that the installation of tongue-and-groove plates is competent!

If you neglect the observance of construction technology, then the installation of tongue-and-groove partitions will end up with the builder getting a shaky and uneven wall, ready to collapse at any moment, instead of a solid monolith.

Kruchenkov FORUMHOUSE user, Moscow.

At home I have a partition in the bathroom made of tongue-and-groove slabs. Apparently, when a hole was made in it under sewer pipe, Something went wrong. Now, if you shake this structure by the edge with your hand, you can hear the blocks knocking against each other.

On FORUMHOUSE you can find a lot of similar examples. And if the partition was originally folded contrary to existing technology, then defects can be corrected only by completely destroying the structure.

But do not be afraid, because the technology for building wall partitions from PGP is quite simple. And if it is treated with due attention, then the impression of the work done will be very positive.

AlexDo FORUMHOUSE user

I've worked in construction. The buildings of the old fund were reconstructed. So, all partitions were made of gypsum tongue-and-groove plates, work is a pleasure. As a partition - that's it. Easily and quickly fit. The walls are even. After puttying, they are ready even for painting, even for wallpaper. The fasteners in the plate hold well. Noise isolation is also normal. But if anything, you can make a crate, lay mineral wool and trim with a trailer or panels.

A little about the practicality of GWP

Gypsum board manufacturers ensure that this material provides secure fastening of standard elements modern interior. This means that GKL partitions can withstand loads comparable to those on walls made of other standard materials. wall cabinets, Appliances, stretch ceiling- all this is mounted without problems on a tongue-and-groove gypsum partition. It is possible to expand the functionality of a wall partition made of PGP by installing metal-plastic water pipes(with a diameter of not more than 16 mm) and elements of electrical wiring.

Grachev68 FORUMHOUSE user

And you can also put doors without extensions in the tongue-and-groove, lay the electrician without problems, hang shelves and TV more reliably.

Tongue-and-groove slabs - what is it

Standard GWPs are of two types: full-bodied and hollow. The construction of solid slabs is more durable, but this material is significantly heavier than its hollow counterpart. For this reason it is not recommended
use as part of partitions mounted on the floor with
wooden joists.

Hollow GWP provide high sound insulation (43 dB) without overloading the floor structure. Some people believe that all kinds of pests can live and multiply intensively in the internal space of hollow slabs. But such an opinion has not yet been seriously confirmed.

Ordinary (solid and hollow) tongue-and-groove slabs are used for partition walls or wall cladding in rooms with dry and normal humidity levels. If the partition is planned to be installed in a room with high level humidity, then preference should be given to moisture-resistant plates that have a peculiar greenish tint. Keep in mind that such GWPs are slightly heavier than regular full-bodied products.

Preparatory work

List of tools for working with tongue-and-groove plates:

• Marking cord:
• Hacksaw with a wide blade and a large tooth;
• Roulette;
• Putty knife;
• Drill with a nozzle for stirring mixtures;
• Bucket;
• Building level and plumb;
• Rubber mallet;
• Square;
• Screwdriver.

In accordance with the manufacturers' recommendations, the length of the wall partition made of PGP should not exceed 6 m. The maximum height of the structure is 3.5 m. It is possible to increase these parameters, but the maximum strength of the partition is ensured only if the specified dimensions are observed.

The base for the wall of the tongue-and-groove slab must be even, stable and completely free of dust. If the floor is concrete, and there are differences on it exceeding 3 mm, then it must be leveled before starting installation work; create a leveling layer. For this, a mortar based on sand and cement is suitable (the mortar grade is not lower than M50).

Alignment of the wall from the GWP.

The solution is applied to a clean dampened floor. To obtain an ideal surface, you can create a kind of formwork and fill it with mortar clearly at a horizontal level. After complete drying, the base must be coated with a primer for concrete.

If you can do without a leveling layer, then the base for the future partition, as well as the junction of the partition to the enclosing walls in 2 layers, are covered with a primer.

If the partition is mounted on a wooden floor, then the base must be reinforced with a strong, even beam.

Kirill147 FORUMHOUSE user

According to the technology, gypsum tongue-and-groove panels require an even base - a screed or a separate non-flexible beam under the partition.

When the base is ready, you can mark the location of the partitions and doorways. This is done with the help of lacing, a plumb line and a level.

Installation of HGP can be carried out at temperatures from -10 to +30°C. Construction material must be brought into the room in advance. This will help him "get used" to the right temperature regime and insures the partition against deformation (when the temperature changes, the plates may slightly change their volume).

Installation of an elastic gasket

To ensure that temperature fluctuations and deformation of the bearing elements of the building do not lead to the destruction of the partition over time, the HGP structure should be isolated from the base and adjacent walls with a special elastic (damping) tape. The damper tape for PGP protects the wall from mechanical damage and increases the soundproofing qualities of the partition. Elastic tape is a special cork backing (at least 75 mm wide), which we will glue to the base and walls in accordance with the markings. Plates and tape are fixed with the same mounting adhesive.

Consumables intended for installation work (building mixtures, gaskets, dowels, suspensions, etc.) should be selected based on the recommendations of the manufacturer of the PWP. At negative temperatures installation of PGP is carried out using a frost-resistant adhesive gypsum mixture.

Glue with a spatula in a thin layer is applied to the prepared surface. The tape is rolled out from above and pressed lightly with your hands. The adhesive sets within one hour. After this period, you can start building the partition.

PGP installation

The damper gasket under the tongue-and-groove slabs is covered with a layer of assembly adhesive, on which the lower, first row of the GWP is laid. The plate can be positioned with a groove up or a groove down - it does not matter. But if the groove is at the bottom, then the comb will not have to be sawn off so that the plate becomes even. It is allowed to install the upper row of plates vertically (if necessary, due to material savings).

During the laying of the first row, the vertical groove of the tongue-and-groove plate and the base of the floor are smeared with glue. Particular attention should be paid to the observance of vertical and horizontal levels. The plates should be planted with a mallet.

The thickness of vertical and horizontal joints should not exceed 2 mm. After installing the next plate in its place, use a spatula to remove excess glue at its joints.

Additional elements for filling the gaps between solid slabs, walls and openings are easily cut from the GWP using a hacksaw.

The relative displacement of the vertical joints in the laying of the PGT must be at least 10 cm. This is a prerequisite for ensuring the strength of the structure.

At the intersection of two partitions made of gypsum tongue-and-groove slabs, as well as at the corners, the slabs are laid in such a way that their joints overlap each other. The tongue-and-groove elements that interfere with the correct dressing device should be cut with a hacksaw.

After the partition is ready, its outer corners must be reinforced with a perforated metal profile and puttied.

It is often asked whether it is necessary to glue tongue-and-groove partitions with a sickle. Yes, the inner corners are glued with a sickle and smeared with putty.

Fastening the partition to the wall

The strength of the junction of the partition from the tongue-and-groove to the walls and the base is ensured by the installation additional elements: mounting angles, fittings or hangers. It is more convenient to use mounting corners or suspensions. After all, they are attached to the plate with the help of ordinary self-tapping screws, and to the walls - with the help of dowels. Plates of the 1st, 3rd, and 5th rows are attached to the side walls. It is possible more often, but there should be several (at least three) mounts. A strong abutment of the base is created for every second slab.

Direct hangers during installation can be installed directly into the groove of the plate, having previously cut them to the required dimensions.

Between the top row of masonry and the ceiling of the room, you will need a technological gap of at least 1.5 cm. It must be left and foamed with mounting foam. After drying, the excess foam must be cut off, and the seam must be puttied. Between the top row and the ceiling, additional fasteners are installed at the same frequency as below.

Creating doorways

For the device of door or window openings, the width of which does not exceed 90 cm, masonry can be done without additional reinforcement. In this case, an auxiliary structure made of wooden beam, which is removed after the slabs of the top row have been laid and the mounting adhesive has set.

If the width of the opening exceeds 90 cm, then a wooden or metal jumper should be installed above it. The ends of the jumper should protrude beyond the opening by 50 cm on each side. This will ensure an even distribution of the load on the partition.

The door (window) frame is attached to the partition using frame dowels and mounting foam.

Interroom partitions from PGP

Inter-apartment partitions made of PGP, unlike interior partitions, are made double. A technological gap of 4 cm is left between the plates. First, one partition is erected, then the second. In order to enhance sound insulation, the space between the plates is filled soundproof material, mineral wool, etc..

Installation of communications

The design of partitions made of PGP allows you to install hidden wiring. Gypsum boards are strong enough to allow vertical grooving and are thick enough to accommodate junction boxes. Technological cavities inside hollow GWP can be used as horizontal strobes.

If the channel selected for laying the wire is expanded with a crown with a diameter of 45 mm, then the cable will pass through it without difficulty. The main thing is not to clog the side hole of the plate with glue during installation work.

In order to make it more convenient to pass the wire through horizontal channels, non-through mounting holes can be made in the side surface of the partition.

Some doubt the safety of vertical chasing of plaster walls. But, according to the manufacturers (and the builders themselves), there is nothing to be afraid of.
