The construction of plasterboard structures begins with the design and calculation of the amount of purchased material. It’s easy to find out the number of profiles and gypsum boards, but determining how many fasteners will be required is more difficult. Let's find out how to count the number of screws per sheet of drywall.

What kind of screws are used when installing gypsum boards?

To fasten drywall to the frame, screws of different lengths are used:

• 25 mm – when installing plasterboard in one layer;
• 35 mm – with two layers of sheathing.

The type of screws is selected based on the frame material:

• the cladding is attached to the profile with metal screws;
• to the beam - on wood.

It is easy to distinguish them: hardware intended for working with metal have more frequent threads.

You should not use one type of screws instead of another: this will certainly affect the strength of the fastening.

The design of the fastener ensures convenience and quality of work:

• Hardware is protected from corrosion by a special coating that gives it a black color.
• The pointed spiral of the thread ensures easy penetration of the self-tapping screw into the metal profile and reliably holds it there in the future.
• The conical head is recessed into the material and does not interfere with subsequent finishing.
• The deep cross-shaped slot on it allows you to screw in a self-tapping screw with a regular screwdriver or screwdriver.

When using a screwdriver, you need to act carefully: there is a high risk of sinking the screw too deep and damaging the material. Makes work easier: due to its design, it limits the depth of screwing in the hardware.

Professionals use . They make the process of installing drywall sheets much easier and faster. But the cost of such a tool is high, so there is no point in purchasing it for a single repair.

Before calculating how many self-tapping screws will be needed for a structure, it is logical to familiarize yourself with the norms and rules for their placement. The following nuances are taken into account:

• The distance between adjacent screws must be more than 10 cm, otherwise the plaster of the sheet will begin to crumble when screwed in.
• When leveling walls or installing partitions, a step of 25–35 cm is taken between the fastening points. It is reduced to 15–20 cm if surface cladding is planned in the future heavy material, such as ceramic tiles.

• More hardware is used for the ceiling sheathing, since they are attached more often: the step is 15–20 cm. The rule works here: the thicker and heavier the drywall, the smaller the distance between the attachment points.
• When installing in two layers, the first one is attached less frequently - every 45–60 cm. The screws that secure the second layer are 10 cm longer. When screwed in, they additionally secure the first one. This reduces the consumption of hardware and eliminates unnecessary costs.
• The number of required attachment points increases when constructing curved structures. Here the pitch between the screws is chosen so as to fix the desired surface shape.

Calculation of the number of screws

It is produced according to the frame diagram drawn up. It is clear that the number and dimensions of the guides, as well as the jumpers between them, will be individual for each case. General recommendations the following:

• For walls, the distance between the guides is 40 or 60 cm. This step allows you to place the joints of the sheets on the surface of the profile.

• The number of horizontal jumpers depends on the dimensions of the room (one sheet of drywall is often not enough in height), as well as on the requirements for structural rigidity (mandatory when constructing partitions, but can be neglected when leveling walls).
• For ceiling structures frames are constructed in the form of cells with dimensions of 40 × 40, 40 × 60 or 60 × 60 cm. This structure ensures a minimum of trimming and joining of elements on the profile.

• 11 self-tapping screws for each rack (the sheet is positioned vertically, its length is 2,500 mm, the fastening pitch is 25 mm).
• For 4 racks – 44 screws.
• Plus 6 - for fastening to the upper and lower horizontal jumpers (three for each - just place one self-tapping screw between adjacent vertical posts).
• In total, 50 pieces will be needed per sheet.

If you decide to change the configuration of rooms, create an arch, or divide the space into several work areas with your own hands, most likely you will prefer to use drywall as a working material. But before you start construction, you need to know how much materials you will need for your purposes. As a rule, an accurate calculation is painstaking work and in order to carry it out correctly, you need to know and take into account many subtleties of the assembly process. To make this task easier, it was developed drywall calculator, which allows you to calculate exact amount Supplies even before purchasing and installing them and avoiding a situation where after repair there remains a large number of unused materials. Use the suggested calculator for calculating plasterboard for partitions very simple - you need to enter the height and width of the object. Based on this data, you will receive information about the number of plasterboard sheets required to complete your work. But besides this, the calculator will help you find out what other materials and in what quantities will be useful to you for constructing a structure when renovating an apartment. By calculating the area of ​​the wall, you will find out how many profiles, dowels, screws and other consumables you will need. Using a calculator not only saves time, but also takes into account all the little details so that your partition is made according to standards, and therefore is stable, reliable and durable.

Drywall consumption calculator for partition is a convenient and easy-to-use tool that allows you, without special knowledge, to calculate the volume of all necessary consumables, as well as their estimated cost.

Due to its high technical and operational parameters, plasterboard is a universal building material that is used for finishing walls and ceiling surfaces. Drywall is non-toxic and non-conductive electricity, suitable for implementing various design ideas. Having experience in carrying out repair and construction work, you can install GC sheets on the ceiling and walls on your own. When planning the finishing of the gypsum board ceiling surface, it is necessary to correctly calculate the amount of material used, calculate the optimal profile consumption per 1 m2, drywall. The gypsum board ceiling is fixed to load-bearing frame, can be “planted” on a wooden or metal frame.

Drywall classification

Given the popularity of drywall, construction market offers a wide range different kinds of this facing building material from domestic and foreign manufacturers. Professionals prefer products from two large, time-tested manufacturers - KNAUF (Knauf) and GYPROC.

Drywall is a material consisting of three layers, two of which are cardboard, connected by a gypsum mass (core), which has a number of useful characteristics. The core provides protection from moisture and fire. The sheet can be processed polymer compounds, due to which the strength of the structure increases.

Some types of gypsum boards have good flexibility and have soundproofing properties when correct organized frame and sealing seams with high-quality putty mixtures.

Important! Drywall is classified into categories depending on the place of application and technical characteristics building materials.

According to the place of application, the following types of Knauf plasterboard are distinguished:

1. Wall. The leaf has standard parameters– thickness – 12.5 mm, length – 2.5 m, width – 1.2 m. The large thickness allows the material to be used for partitions, ceiling structures, and for cladding wall surfaces.
2. Ceiling. It is permissible to use material for organizing ceiling structures of a standard thickness or a thickness reduced by 3-4 mm, since installation is much easier using more lightweight drywall. For lightweight gypsum plasterboards, a smaller amount of profile will be required.
3. Arched. GK sheets are flexible enough to create complex structures various forms, arches Using the arched Knauf in interior design, you can implement various design projects.

To choose the right plasterboard for finishing the ceiling, you need to take into account the classification of the material depending on its functions. This parameter will allow you to determine the technical, performance characteristics building materials, select gypsum boards depending on the functional characteristics of the premises. High quality drywall“Knauf” has a special marking indicating its type.

Classification of plasterboard "Knauf":

1. GKL. Drywall covered with cardboard on four sides.
2. GKLV. Moisture-resistant drywall is resistant to the formation of condensation, mold, and prevents the colonization of pathogenic flora on the surface of the material. GKL "Knauf" is used to create ceiling surfaces in rooms with high humidity. GKLV is painted green.
3. GKLO. Plasterboard sheets have increased resistance to high temperatures, fire resistant. They have quite heavy weight, therefore their installation is carried out in the most fire hazardous areas.
4. GKLVO. Fire-resistant material with increased resistance to moisture.
5. GVL. Gypsum fiber sheet made of fire-resistant non-combustible gypsum mixture, crushed paper.

GKL, GKLV, GKLO are used to create partitions and for cladding wall and ceiling surfaces. GKLV provides additional thermal insulation. Gypsum fiber "Knauf" - perfect solution for basements, attics, rooms where the humidity level exceeds 65%.

Design of a suspended ceiling structure made of gypsum plasterboard

From a constructive point of view, a suspended ceiling made of gypsum plasterboard includes:

1. Suspensions, profiles, fixed to load-bearing structure hardware.
2. Metal frame, less often wooden slats are used. Connected into a single frame couplings, brackets. Using metallic profile, you can build a cellular, rail frame. The metal frame can be one- or two-level.
3. Plasterboard panels fixed to the frame.

Important! Despite the fact that the cost wooden frame will be cheaper, professional craftsmen to create a reliable, robust construction It is recommended to use a metal frame.

When planning to install gypsum boards yourself, you must follow the technology, the sequence of work, prepare the necessary equipment, tools, purchase more than one type of profile, hardware (screws, screws, dowels), and reinforcing mesh.

Calculation of materials for HA ceilings

When calculating the materials needed for work, it is necessary to take into account the type, type of drywall used, area, functional features premises. As a rule, sheets are produced standard length. The material may differ in width, thickness, weight. The acceptable thickness for suspended ceiling structures made of gypsum plasterboard is 8-9.5 mm.

For correct calculations required quantity building materials per meter square area, take into account:

• type of drywall;
• type of supporting, supporting structure (frame, profile, hangers);
• materials for finishing cladding.

When performing calculations of civil code per square meter, the dimensions and footage of the premises are taken into account. It is best to make a preliminary plan future design, which will allow you to make correct calculations and find out how many materials are required to create the structure. Indicate the dimensions of the room and the placement of the profile.

Guide profile quantity

To find out the required number of profiles per square meter, divide the perimeter by the length of the segments. Guides can be purchased three to four meters long.

Important! The number of ceiling profiles is calculated based on the calculation of 3000 mm per square meter of area.

How to calculate connectors, hangers for a profile

The formula will help determine the number of connectors for the profile: K= S*2, where S is the area suspended ceiling, K – number of crab connectors. For example, for a room with an area of ​​6 m2, 12 connectors will be required.

If the area of ​​the room is more than eight square meters, the calculation of the material is carried out according to the formula: K = S * 1.7.

Consumption of hardware for drywall

Fixing drywall to load-bearing profiles carried out using self-tapping screws, screws, dowels. The screw is screwed in with a screwdriver or screwdriver. The sheets are fixed to the metal frame perpendicular to the built-in guides. The HA sheet should fit as tightly as possible to the frame. The screw and self-tapping screws are attached in increments of 30-35 cm. To enhance the strength of the structures, the spacing between the screws can be reduced to 15-10 cm. The screw is fixed so that its head is recessed by 1 mm.

Important! Self-tapping screws are placed at least 10-12 mm from the edge of the sheets, and 15 mm from the cut side. Otherwise, cracking of the building material may occur.

When calculating the number of screws, take into account:

• size of gypsum boards, slabs;
• hardware fastening step;
• number of layers of drywall.

If the HA sheets are installed in several layers, the fixation is carried out in different steps. For example: the first layer is attached in increments of 50-60 cm, the second - 35 cm. One sheet will require 65-70 pieces of hardware. In the case of a two-layer structure - 110-115 pcs.

While creating complex shapes plasterboard is attached to a metal frame the desired shape, using a pre-prepared template in which the sides can be made from plasterboard sheets.

Calculation of mass per square meter of partitions from HA

This parameter will allow you to calculate how much building material is required, the level of load on the floors created by the structure, which is especially important when arranging attic and attic spaces. Below is a calculation that can be used when standard sizes plasterboard sheets:

1. If the partition has a height of five meters, the mass of one “square”, sheathed on both sides with plasterboard, will be 25 kg. If the partition has a greater height, thicker material is used to organize it; accordingly, the weight per square meter will increase.
2. A two-layer 6.5-meter partition with a single frame will have a mass per 1 m2 of approximately 40-45 kg.
3. If the partition is built on a double frame, there is a gap for engineering communications, a square meter will weigh 48-50 kg.
4. When organizing structures with one layer of HA, one square meter will have a weight of 30 kg.

The weight increases if a metal frame was used for the structure. If the frame is made of wooden slats, the weight will be less, but the partition should not be higher than four meters.

Material consumption per 1 m2 for suspended ceiling

Let us give an approximate calculation of the consumption of building materials for a structure created on metal frame from gypsum plasterboard of standard thickness:

• guide profile – 0.8 m;
• rack, ceiling profile – 2.3 m;
• direct suspension – 2-3 pcs;
• reinforcing tape – 1 meter;
• self-tapping screw 9 mm – 4-5 pcs., 25 mm – for a suspended ceiling – 23-26 pcs.;
• dowel, corresponding screw – 5-6 pcs.

Video: calculation of materials for plasterboard ceiling structures

The main attribute of almost any renovation, especially European-quality renovation, is plasterboard structures. And this is not surprising. Indeed, from gypsum board (GVL) it is now possible to “blind” practically any partition or ceiling. For example, for a device multi-level ceiling Drywall is most often used.

In addition, these structures are quickly erected and are relatively inexpensive. True, there is one drawback here - a rather large range. So, if you decide to independently build partitions and a ceiling from gypsum plasterboard sheets in your apartment, and at the same time comply with all technology, then you will have to stock up on more than one type of profile and screws. You will also need dowels, reinforcing mesh, putty, primer, hangers and connecting elements.

All this must be purchased in the required quantity (or with a small margin) for a given design. And for this you need to calculate required amount plasterboard and profile for the ceiling or wall (partition). Therefore, for those who want to build similar structures, it was created this page, which shows an example material consumption for the most common plasterboard structures:

• ceiling;
• wall structures;
• partitions.
