Arch in the doorway with your own hands. Do-it-yourself step-by-step instructions for installing a drywall arch with your own hands

Often, the builder faces the task of building an arched ceiling, arranging a domed roof or an original "humped" bridge over a pond, which is becoming an increasingly popular small architectural form. At the same time, in most cases, masters do not bother themselves with complex calculations, using two quantities that are known even to a seventh grader. Such values are the width of the span, subsequently covered by the arch, and the height of the rise of the arch, which is calculated by determining the distance between an imaginary horizontal line drawn between the points on which the arch rests, and highest point arches. According to experts, these values \u200b\u200bare not enough to equip a reliable arch with high performance. The main role in the design of the arched ceiling is given to the choice of materials from which the arch will be built, and the associated calculation of the arch, the correctness of which determines its subsequent performance characteristics. Following these recommendations, you can design a reliable arched ceiling that will become great solution and not only diversifies the design of the apartment, but also becomes an excellent decoration landscape design garden. Specialists in this field will easily make all the necessary calculations, but what if it is not possible to use their services, and you have to do all the work yourself? In this case, use our recommendations that will help you cope with the task as efficiently as possible.

Arched systems from a professional point of view

From the point of view of specialist engineers, arched structures are called systems of a broken or curvilinear nature, on the supporting elements of which vertical loads act, leading to inclined reactions directed inside the opening. The horizontal component of such a support reaction is the spacer, which indicates that the arched systems are spacer structures. This is their main difference from beams, which experience only normal mechanical stress. In modern construction, arches are used as the main load-bearing structures facilities for various purposes, whether it is economic, industrial or agricultural buildings, with a span of 12 to 70 m. As for foreign construction, in this industry the design of arched spans is even more developed, which allows the construction of arches up to 100 m and more high.

Arch classification: main varieties

According to static circuit , distinguish hingeless , two-hinged and tri-hinged arches ;

Also, the supporting ends of the arch can be connected by a horizontally located rod that perceives a horizontal load and is called puff . The calculation of an arch with a puff is somewhat different from the calculation of a two-hinged arch or a three-hinged arch without a puff.

Each of these types has its own advantages and disadvantages, and therefore, the choice of design is carried out by a design engineer who will calculate a three-hinged arch, taking into account the strength requirements for it, the materials used to construct it, and the architectural tasks that are assigned for one structure or another.

In accordance with the scheme of support, allocate drawstring arches and arches without tightening . If the former perceive the thrust, then the thrust of the latter is transmitted to the supports. Puffs are made from profile steel or fittings. If the operation of the arch will be carried out in aggressive environments that promote metal corrosion, the use of wooden glued puffs is allowed.

The form is distinguished:

Triangular arches, consisting of straight semi-arches. Calculation triangular arch is not difficult, and you can make it yourself;

Pentagonal arches;
Segmental arches, the axes of the semi-arches of which are located on a common circle;
Lancet arches, consisting of several semi-arches, the axes of which are located on two circles;

How to calculate a three-hinged arch with a puff: recommendations from experts

If you plan to install a small arch, the calculation and design will not give you any particular difficulties, since it is preferable to use sheets of building material of huge sizes, such as plywood, drywall or OSB boards, for their production. The largest indicators of their length and width are 250 and 120 cm, respectively, which allows you to simply draw an arch on a sheet of material and cut out at least two component parts bearing beams. In conclusion, such arches are sheathed with sheet material, after which we can assume that the arch is ready. Despite the speed and ease of installation of arches by this method, it is also characterized by its drawbacks, among which a large number of the material spent on waste, the decorativeness of the finished arch and the inability of the structure to bear the load.

The arrangement of arched structures becomes much more complicated if the master is faced with the task of mounting an arch over a large gap (up to several meters) or an arch that can withstand the highest loads. Due to the fact that it is difficult to find materials on the construction market, the dimensions of which allow the installation of such an arch, it is designed as a stacked structure consisting of several parts. In this regard, the master faces the task of accurately calculating the arch and determining the dimensions of its parts.

As mentioned earlier, arches are distinguished according to parameters such as shape, size and height, and before implementing a wooden arch calculation project, it is necessary to have a clear idea of \u200b\u200bthe design and approximate dimensions of the desired arch. Given these parameters, it is easier to decide on the choice of materials for its installation and subsequent calculations.

Amateurs, having heard the phrase “arch calculation”, are often frightened, however, the calculations in this case are simple and are based on the use of school formulas from geometry. In addition, in order to facilitate the calculations, it is necessary to draw the contour of the arch on a graph paper on a somewhat reduced scale. After that, an arch template is made in real size, having which you can most effectively carry out further calculations, since you can attach the so-called copy of the arch to the place of its installation and evaluate the correctness of the calculations. To make a template, you can use thick cardboard, plywood or a sheet of fiberboard.

Arched structures occupy a vast niche in architecture, and their use is the broadest topic that cannot be covered in one article. In this material, we will consider the manufacture of an arch in an apartment or a private house, since a traditional rectangular opening, designed in the form of an arch, will become an exclusive interior detail of an apartment that distinguishes it from other apartments.

Consider an example of calculating a three-hinged arch:

In most cases, regardless of the experience of the master, he knows three parameters of the arch, including the width of the span covered by the arch, the height of the arch, and the depth (width) of the wall. At the same time, the master is faced with the task of calculating the parameters of the details of the arch, assembling them into a single arched structure and firmly fixing it.

Method number 1 - empirical

Although any calculation of an arch begins with the calculation of the radius of its circumference, the arch does not always represent a circular arc. There are situations when the arch consists of two arcs (this applies to arches made in the Gothic style) or are characterized by asymmetrical outlines. In this case, the calculation of each arc of the arch is performed separately. But, back to the calculation of the circumference of the arch. It is more convenient to produce it on paper, while reducing the size, on a scale, for example, 1: 50. Having prepared paper and compasses, we draw a doorway on the sheet, taking into account the scale and draw an axis of symmetry dividing the opening in half. After that, the axis of the compass must be changed by placing the leg with the needle directly on the axis of symmetry. Next, you need to draw several arcs and, choosing the most optimal one, remove the rest with an eraser.

To better demonstrate this example, let's draw an arc of an arch:

where R is the radius of the circumference of the arch, and L is half the chord of the arch, while the chord size corresponds to the length of the arch opening. As for H, this indicator displays the height of the arch.

Method number 2 - mathematical

To carry out a mathematical calculation of the radius of the circle of the arch, use the Pythagorean theorem, according to which:

R= L2 + (R2 - H2)

R= L2 + (R - H)2

Having expanded the binomial, we transform the expression into the form:

R2 = L2 + R2 - 2HR + H2

Subtract R from both parts and get:

L2 + H2 - 2HR = 0

Let's move the term with R beyond the equal sign:

2RH = L2 + H2

And finally, we get the desired R:

R = (L2 + H2)/ 2H

Important! The formula for calculating the radius of the circle of the arch: R = (L2 + H2)/ 2H , where R is the radius of the circle of the arch, H is the height of the rise of the arch, L is half of the chord of the arc (the length of the arched opening).

Due to the fact that the arch consists of several parts, for the manufacture of which it is necessary to use a board of a certain width, we will calculate the dimensions of the part that can be made from a board with specific dimensions. To do this, you need to solve the inverse problem. Taking into account the known radius of the arch and the height of its rise (in this case, this is the width of the board), we calculate the maximum possible length of the part that can be made from a board with a certain width, that is, we will calculate the length of the arch. Due to the fact that we already know certain ratios from previous calculations, we derive the following formula:

L2 = 2RH - H2

HR-H2

In order to properly make the arch, it is necessary to prepare a few more parts, taking into account the fact that they will have to be joined during the installation process. The docking method is selected depending on the purpose of the arch. The use of overhead parts along the "cheeks" of the arch and the joining of two arches is practiced, taking into account the shift by half the part.

In the process of calculating the details, it is necessary to take into account which side of the arch, depending on its location in relation to the details, we are most interested in (internal or external). Simply put, we need to understand how the supporting parts of the arch will be located in relation to the arch itself. For example, when arranging a domed roof, the supporting parts of the arched structure will be located below the arch, and when installing the arched vault - above. There are situations when it is necessary to equip a two-sided arch. In the latter case, the calculation of the details of the arch will be carried out according to the smallest rounding.

If during operation, the arch will carry high loads, it is necessary to strengthen it with the help of various beams and puffs installed between the arch nodes. Thus, you can equip a supporting truss that can withstand increased loads.

If you decide to equip the arch in the Gothic style, you need to determine the radius of the arch at the ends as accurately as possible. In this case, you will make it easier for yourself by using the empirical method of calculating the arch, with the help of which you will experimentally select the rounding point of the arch, then from this point draw a line down parallel to the wall, measure the resulting distance and draw a line of the same length on the other side. Then the leg of the compass is placed on this line, the distance (radius) is determined and, moving down or up parallel to the line, the point is determined where the wall line and the arc of the arch will close through the second (smaller) arc. On the second side of the drawing, you need to do the same.

To make it easier for yourself and calculate the arch as efficiently as possible, you can make several drawings and choose the most suitable one. As you already understood, the above examples of calculating the arch are far from the only ones, and there are other calculation methods, however, the empirical method clearly demonstrates to you how the arch will look after installation. In addition, in the process of making calculations, you can easily adjust the drawing until you achieve the desired result.

Having made a drawing and making sure that it is correct, it is necessary to make an arch template, using which you can easily mount any arched structure.

A few words about the choice of material for the arch

For the manufacture of the arch can be used various materials, including metal (the calculation of a metal arch is made a little differently), as well as brick and concrete, but the simplest and cheapest way is to make a drywall arch. Due to the fact that the arch made of brick and concrete will be very heavy, it is necessary to mount a reinforcing cage for it. The fittings are easy to bend, and you can easily weld a frame out of it. After that, using a puncher, it is necessary to drill holes in the walls, drive pins into them and weld an arched frame to them.

Making a drywall arch is much easier and faster, but the finished structure will be less durable than its brick or concrete counterparts. To do this, it is necessary to make a frame from tin profiles, sheathe them with drywall on the sides, and use segments for lining the internal opening (for their manufacture, drywall is cut on one side, bent and finally fixed with self-tapping screws). The resulting edges must be smoothed with putty.

Calculation of a brick arch: highlights

To carry out the calculation of a brick arch, it is also necessary to make a template from fiberboard, the quality of which largely determines the performance and appearance future brick arch. First of all, it is necessary to calculate the dimensions of the template, which will require knowledge of the width of the arched opening. For example, the width of the arched opening is 15000 mm.

Since the width of the template should be 5 mm less, then it will be 1495 mm. Even if the template swells from moisture, you can easily dismantle it in the final stages of work. The height of the template should correspond to the height of the arch, in our case, let it be 168 mm. Since the whole facing brick it is recommended to put in the upper part of the arch, it is necessary to calculate the number of bricks. Since the height of one row is about 72mm (brick height + joint height), and the total number of rows is 4, the arched height is 72*4 - 120 = 168mm. (120mm at the same time - the height of the brick laid on the edge).

In conclusion

Most often, the installation of arched structures is carried out for decorative design space, regardless of its purpose. It can be a house, an apartment, or an office.

Often, with the help of an arch, they make out a doorway between the kitchen and the living room. However, the installation of the arch can also be used in the process of larger types of construction. If you plan to decorate the interior of the room with the help of an arch, experts recommend making an arched structure from drywall, as it is much cheaper, easier and less labor-intensive. At the same time, the finished structure will not yield to arches made of brick or wood. In order not to be disappointed in the beauty and correctness of the arch, experts recommend approaching the installation of the arch structure with due care and calculating the arch, which can be done in several ways. In our article, we have offered you two of the most common and effective ways calculation of the arch, using which you can build a reliable and aesthetically attractive arch.

How to make an arch in a doorway? This question interests many owners of apartments and private houses.

It should be noted right away that the arched opening can ideally look only in rooms with high ceilings.

At low ceilings such a structure visually significantly reduces the opening. Therefore, you should think carefully before deciding to build an arch. If you accepted it, then you can find a lot of materials to implement the idea.

Methods for constructing arches

How to make an arch instead of doors? Today there are such ways to create arches:

For an arched opening, a wall is hollowed out according to a pre-made markup. This method is more suitable for rooms with not very high ceilings.
With a sufficient height of ceilings and doorways, their upper part is sealed with pieces of drywall or plywood to give them an arched shape.

When chiselling a wall, proceed as follows:

You need to remove all decorative trim including door frame.
From the floor itself, a vertical line is marked on both sides of the opening to the height of the future arch. For accurate marking, use a level or plumb line.
The width of the marked opening is measured and divided in half. It turns out the value of the radius of the arch.
The center of the arch is marked on the upper horizontal line. A screw, self-tapping screw or nail is fixed at this point.
A strong thread is tied to a self-tapping screw, the other end is attached to a pencil. The excess thread is wound around a pencil, leaving a length equal to the radius of the arch.
A mark is made on the vertical from the center point of the line down at a radius distance.
A semicircle of the upper part of the arch is outlined.
On the other side of the wall, the marking operations are repeated.

Now you can start swotting with a puncher or other tool. The choice of tool depends on the material of the wall. It is recommended to drill as many holes as possible along the outlined contour. They will help in the chiseling process. AT wooden wall the opening is cut with a jigsaw or a hacksaw with a narrow blade. The final stage of the preparatory work is the processing of the edges of the resulting opening and the design of it with prepared materials.

For high ceilings door arch You can, if you follow this sequence of actions:

In the opening, the frame of the future arch is assembled from wooden or metal profiles.
Plasterboard or other material is marked out from which rectangles need to be cut. Their width is equal to the radius of the arch, the length is equal to the width of the opening. Using a large compass or thread with a pencil, the upper arcs of the arch are marked and cut out with a jigsaw.
The resulting blanks are attached to the frame with hardened self-tapping screws. Their hats are recessed 0.5-1 mm into drywall.
The end of the opening is closed. You can do this with DVP. This material bends quite well. You can use a strip of drywall with a thickness of 8 mm. It is rolled several times with a spiked roller and sprinkled with water. Punctures are made to a depth of up to half the thickness of the drywall sheet.
If there is no needle roller, punctures can be made with an ordinary awl. The distance between them is about 1 cm. They are made only on the side where the part will be bent. After some time (approximately after 1-1.5 hours), the gypsum soaks and the strip bends quite easily. It is better to bend it on a wooden or plasterboard template. After drying, it becomes hard again.
Plasterboard putty and make out the arch at its discretion.

arch configurations

The arch in the house gives the premises a certain personality. There are many configurations and forms of arched openings. Let's consider some of them:

The classic version is suitable for rooms with a height of 3 m or more. The arch of the correct form has a bending radius of 45 cm or more. If you add it to the height of the doorway, then the total height of the room simply may not be enough.
The Art Nouveau arch is often erected in typical apartments. Its radius exceeds the width of the doorway, so there are corners between the vertical elements and the arc. They can be made sharp or rounded.
Romantic style - a variant of the arch for openings of large width. Between the corners with roundings, a horizontal insert can be placed, you can install it at an angle.

The configuration of the arch depends on the desire and aesthetic taste of the owner of the home. The arched opening can be wavy, polygonal, illuminated, with various niches and shelves, with stained-glass windows, and so on.

Materials for equipment arches

Arched opening can be made from monolithic concrete, plastic, brick, metal, wood, chipboard, fiberboard, plywood, plasterboard and other materials. When using brick, concrete or stone, their weight must be taken into account. For such structures, a special foundation and reinforcing elements for bonding with walls may be required.

Metal is a material that fits into any style. But not every metal is suitable for these purposes. The stainless steel option is very expensive. Galvanized iron in the interior does not look. It is quite difficult to make complex figures out of metal.

Wood is a beautiful material of natural origin. It practically does not require additional finishing.

The best processed and allow you to perform arches of any shape drywall, fiberboard and particle board. These Construction Materials can be trimmed with plaster, painted, covered with a layer of decorative or ordinary plaster, wallpapered, lined with decorative stone.

Plastic is a material that is easy to process. Plastic structures do not require additional processing and finishing.

For the design of arches, ready-made structures from different materials are also sold.

The appearance of the arch should match the overall design of the room. Each side of the opening can be decorated in different ways.
Any work on the construction of arched openings begins with the dismantling of the door frame.
For convenience and speed up the marking process, it is recommended to use a full-size template. It can be made from cardboard.
During construction curved elements frame made of metal profiles, slots are made on them that allow you to bend the workpiece. The cuts are made in increments of about 5 cm.
For work, a drill or a puncher, a hammer, scissors for iron and a hacksaw are usually used. Sometimes other tools may be needed.
The frame is attached 10-12 mm deep into the doorway so that the drywall attached to it is flush with the wall after puttying.
The assembled structure is treated with sandpaper and putty. Surfaces and corners can be covered with fiberglass mesh.

Do you want to functionally and visually zone the space of the apartment, but there is no desire to install standard interior doors? Then your choice is drywall arches. They not only divide rooms, but also effectively decorate doorways, making them more original. In addition, these beautiful designs do not require large expenses - they can even be made by hand. How? To get started, find out the features of different types of arches and evaluate the photos of finished products in the interior to decide on the design of the model. Then read the step-by-step instructions and watch the video explaining all stages of installation. And then you can confidently proceed with the installation of the arch. Further about all this in more detail.

Choose the type of arch

home distinguishing feature each arch is the form of a vault. It is she who serves as a criterion for the classification of products. So, the following types of arches are distinguished:

classic - a traditional version with a semicircular arch, the center of the section of which runs exactly in the middle of the doorway;
portal - laconic arches with a rectangular vault;

segmental - an asymmetric arch, the vault of which consists of two elements: one repeats the shape of the portal, and the second - the classical model;
modern - semicircular arches with a non-standard radius of curvature of the arch - more or less than the classic radius of half the width of the doorway;
romantic - a kind of portal arch with neatly rounded corners.

Advice. When choosing the shape of the arch, you should consider the size of the rooms. If the ceilings in your apartment or house are low, it is better to refuse classic variations - they somewhat hide the space. And for very low rooms, it is better to choose arches without pronounced rounding at all - segment or portals.

Getting ready for installation

Before proceeding with the direct construction of the arch, you need to perform several preparatory work. The first is the preparation of the necessary tools and materials. In particular, you will need:

drywall sheets: two canvases 12 mm thick and one for the arch - 6.5 mm thick;
metal profiles - at least 6 pieces;
two arched corners;
dowels and screws;
hacksaw for metal;
drywall knife;
perforator, screwdriver and drill;

Drywall arch installation tool

building level;
pliers;
roller;
gypsum putty and spatula;
primer;
sandpaper;
pencil and tape measure.

Next, you need to prepare the opening for installation new design. First of all, you need to eliminate the door frame - this will help to significantly increase the area of \u200b\u200bthe opening. After dismantling, it is necessary to carefully clean the surface from various exfoliating materials, dirt and dust.

After completing the preparatory stage, proceed with the installation of the arch. Start by assembling and installing the frame structure.

We construct the frame of the arch

The construction of the arched frame consists of the following steps:

We mount drywall on an arched frame

After the arch frame is installed, it must be sheathed with drywall. Start from the side parts: screw the prepared canvases to the metal guides with screws in increments of 15-20 cm.

Advice. Screw the self-tapping screws in such a way that their hats “sink” into the drywall - so they do not interfere with the finishing work and subsequently will not spoil the appearance of the arch.

Next, you need to fix the drywall on the curved top profile. This is the most difficult procedure, since the material, on the one hand, does not bend well, and on the other hand, it can quickly deform under force. The best way out of the situation is to wet the drywall a little and, carefully bending, fit it under the frame. When the desired arch radius is reached, attach the drywall elements to the curved profile using self-tapping screws. Then the finished upper part of the arch must be connected with the same self-tapping screws to the side walls of the structure.

We process and decorate the arch

The last step in creating a drywall arch is finishing and designing the structure. The first procedure is performed in several stages:

Walk along the surface of the arch with sandpaper to eliminate all roughness and irregularities.
Fasten the arched corners to the putty - they will keep the shape of the upper part of the structure.
Treat all mounting seams with putty.
After the putty is completely dry, smooth out all the bumps again.
Cover the surface of the arch with a primer, and after it dries, apply a finishing putty on top and sand the structure again.

wallpapering is a simple option with great possibilities: thanks to the variety of textures, colors and patterns, you can choose a lining for absolutely any style. It is best to use non-woven - they are not only aesthetic, but also durable.
painting - this decoration option is good for its practicality: the painted structure can be washed an unlimited number of times. Choose water-based paint- its colors are more saturated.

sheathing with fabrics is a non-standard finish that will give your arch a more noble look. The choice of fabrics is unlimited - from laconic cotton to exquisite jacquard.
decorative patterns are a very easy decorating idea to implement: you only need template stencils, spray paint, a protective film and your own imagination.

A drywall arch is a spectacular and relatively simple way to transform the interior of a home. with my own hands. All you need to do is follow the instructions and do all the work step by step. And the result will not keep you waiting long - you will get an original and original doorway instead of the usual interior door.

How to make an arch with your own hands: video

Drywall arch: photo

Starting to repair an apartment or house, people strive to make their home as comfortable, stylish and elegant as possible. One of the most popular design ideas is clearance doorway in the form of a semicircular arch. Having studied the technology, it is quite possible to make an arch from GKL with your own hands.

Using an arched structure, you can influence the design of the entire environment and set the tone for the arrangement of the entire interior.

Arched structures are used not only for decorating doorways, but also for zoning the corridor. In this article, you will learn how to make an arch from GKL with your own hands.

Necessary tools and material

From the tools you will need a screwdriver, tape measure, construction square, pencil, spatula, grater, container, knife, sponge, drill, jigsaw, metal shears.

Draw the outline of the arch on the drywall. To draw the upper part of the arched structure, use a home-made compass from a self-tapping screw screwed into drywall and a thread tied to it with a pencil

The greater the length of the thread, the greater the radius of the arc. Here you have the opportunity to experiment until you get the shape of the arch you need.

The blade of the tool must cut through the material strictly according to the markup - the quality of the arch directly depends on this. Next, start creating the arched frame. It can be metal or wood. Both options have their merits: aluminum profile characterized by evenness and lightness, and the tree is distinguished by great strength.

If you have a concrete wall, then you first need to make holes with a drill, insert dowels into them and only then screw in the screws.

Then, after attaching all the profiles to the wall, start the installation of the plasterboard. Sheets are installed using a screwdriver. The size of the screws depends on the thickness of the drywall.

Fasten the curved aluminum profile along the edge of the drywall. This will increase the rigidity of the structure. First, attach both ends of the curved track to the metal frame, and then screw the drywall sheets to it. You need to screw in the screws in increments of 0.1-0.15 m.

Mount perpendicular pieces of the profile to connect the side walls of the arched structure to each other.

Fix the lower arched arch section. Using a tape measure, measure the length and width of the arc. Cut out the appropriate piece from the gypsum board. Attach it to the bottom of the arch, gently bending to give the desired shape.

The edges of the drywall rectangle should be flush with the walls of the arch. Fix the section with self-tapping screws on both sides of the arc. Read from the center of the arch.

Inspect the resulting design and eliminate minor defects. Proceed to finishing. Tape the edges of the drywall with fiberglass mesh or paper tape.

Apply putty (minimum 3 coats). Sand thoroughly with a grater. The arch is ready. It remains only to paint it.

Varieties of arches

Exist different types drywall arches. They usually differ in the configuration of the top, and in some cases in the way they are connected to the vertical segments.

The photo of drywall arches shows that they are usually divided into six types:

Classic.
Modern.
Romance.
Ellipse.
Trapeze.
Portal.

Also, a semi-arch is separately distinguished.

It is not so difficult to make and mount an arched structure yourself. You just need to study the technology and choose the appropriate design of the drywall arch. We wish you success.

Photo of drywall arches

Arches in openings have been used for a long time, as it was believed that this architectural opening is very aesthetic. Today, the arrangement of arches in doorways has become popular due to the fact that they are easy to mount from drywall. With the advent of drywall arches, it became possible to separate rooms without making any special efforts. Such arched vaults will help to give individuality to each room.

Thanks to the arch, you can visually expand the small space of the corridor, kitchen or room.

As for the forms of the arch, there are a lot of them. By making drywall arches, you can recreate almost any historical copy. The main convenience is that drywall is a very flexible material. We make an arch in the doorway according to the following scheme:

All necessary measurements are taken and the required amount of material is calculated.
Next, prepare everything necessary tools required for work.
The front parts of the arches are cut out, a frame is made of a profile or wood.
Next, the front elements of the arches are attached.
The lower parts of the arches are cut out and also fastened.
Arched corners are attached and all surfaces are puttyed.

What materials will be needed?

To work, you will need the following materials and tools:

Types of arches.

drywall 9.5 mm thick;
guide profiles - 27x28 mm;
rack profiles - 60x27 mm;
self-tapping screws for fastening GKL (gypsum plasterboard) - 3.5x25 mm;

What kind of arch can be?

The opening of a door or window can be decorated by creating an arch. There are a large number of arches that can be made in your home. When choosing, you need to be guided not only by taste preferences, but also by the following parameters: first of all, the height of the ceiling and the width of the doorway. So, some designs look good with high ceilings, while others, on the contrary, with low ones. Kinds:

Scheme of the arch device.

Portal - this arch is performed as a standard in the form of the letter P. The device of the arch can be different: polygonal or wavy. It all depends on the materials available and the imagination of the owner of the house.
Classic arch - otherwise called "classic". This type of arch is only suitable for ceilings that are over 3m high. On average, with an opening width of 90 cm, about 45 cm of height will be occupied by the bend of the arch, so a height of 2.5 m may not be enough.
Romance. This option great for wide openings, relatively small in height. Between rounded corners, a straight insertion is made, either at an angle or horizontally.
Modern. This type is great for making a doorway inside standard apartment. In this case, the corners can be both rounded and sharp.
Semiarka. This option is able to perfectly perform zoning of the room.
A straight arch is a great option for high-tech and modern rooms.

In addition, the arches differ in their design:

Radius (asymmetric) is the simplest and at the same time the cheapest technology that will suit absolutely any interior.
Multilevel. This design is used mainly in cases where the interior is made in one particular style.
Openwork is suitable for all cases, except for those when the walls are made in a non-standard form.
Domed and symmetrical are suitable for classic arches, the opening of which is at least 1 m.

Doorway: taking the necessary measurements

Drywall sheet bending methods: dry and wet.

Before making an arch in the doorway, you need to make all the necessary measurements. Naturally, you need to start with measurements of the opening. You need to know the height and width of the opening.

GKL preparation for the arch

First of all, you need a regular pencil and a tight rope. The pencil is tied to a rope and an excellent large-scale compass is obtained.
Further, the middle is marked on the GKL - that is, the radius of the future arch. To do this, remember the size of the width of the opening.
Where the top of the arch will be, there is a mark of 60-65 cm. This figure was taken at the rate of 50 cm in radius and 10-15 cm in height above the arch.
Next, the drywall sheet is cut exactly along the width of the doorway.
After that, a point is marked, which will be the center of the radius.
A rope with a pencil is taken, its length should be equal to the radius. A semicircle is drawn along a pre-marked point. While doing correct measurements you should get a perfect circle, which will be the arch of the opening.
After that, a clerical knife or a jigsaw is taken, with which you need to cut a semicircle along the drawn line. In our case, its width should be 100 cm, and its height 60-65 cm.

Do-it-yourself installation of the frame for the arch

Both the aesthetics and the strength of the structure will depend on a well-executed frame.

The stages of manufacturing and installation of the frame are as follows:

First of all, a guide made of metal profile with dowels. Next, the guides are attached to the wall in 2 places.
After that, an already arcuate profile is made, also made of metal. For its manufacture, with the help of scissors for metal, identical cuts are made in the profile, each of which then needs to be bent to form a right angle. As a template, you can use already made parts from GKL. The profile is fastened with dowels, and drywall is already with self-tapping screws. For the arch you will need 2 arcuate profiles.
To strengthen the frame between 2 arcs, you need to attach profile segments.
Further, the arcuate parts are attached to the frame using self-tapping screws.
